Introduction
• Cytogenetics is essentially a branch of genetics, but is also a part of cell biology/ cytology (a subdivision of human anatomy), that is concerned with how the chromosomes relate to cell behavior, particularly to their behaviour during mitosis and meiosis. Techniques used include karyotyping analysis of G-band chromosomes, as well as molecular cytogenetics such as fluorescent in situ hybridization (CGH). Cytogenetic approaches to studying chromosomes and their relationship to human disease have improved greatly over the past several decades.
As a mature enterprise, cytogenetics now inform genomics, disease and cancer genetics, chromosomes evolution and the relationship of nuclear structure to function. Cytogenetics involves testing samples of tissue, blood or bone marrow in a laboratory to look for changes in chromosomes including broken, missing, rearranged or extra chromosome. Cytogenetics may used to help diagnose a disease or condition, plan treatment or find out how well treatment is working.
Chromosomes
Chromosomes are the rod shaped; dark-stained bodies seen during metaphase stage of mitosis. The chromosomes are the nuclear components of special organization, individuality and function. They are capable of self-reproduction and play a vital role in heredity, mutation, variation and evolutionary development of the species. Chromosomes are thread-like structure located inside the nucleus. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. The number of chromosomes is constant for a particular species. Therefore, these are of great importance in the determination of the phylogeny and taxonomy of the species. The number of chromosomes varies from species to species but the number remains constant in a species. But sometime, due to certain accidents or irregularities at the time of cell division, crossing over or fertilization some alteration in morphology and number of chromosomes takes place. Humans have 23 pairs of chromosomes-22 pairs of numbered chromosomes, called autosomes, and one pair of sex chromosome, X and Y. Each parent contributes one chromosome to each pair so that offspring get half of their chromosomes from mother and half from their father.

This book, “Meteorology and Geography” is designed to equip aspiring fisheries professionals with a foundational understanding of the atmospheric and terrestrial processes that profoundly influence aquatic ecosystems and, consequently, the distribution, abundance, and health of fish and other commercially important species. For too long, the study of fisheries has sometimes been perceived as largely focused on the biology and ecology within the water itself. While these aspects are undeniably vital, the reality is that aquatic environments are not isolated entities. They are inextricably linked to the atmosphere above and the land surrounding them. The weather patterns we experience daily – from sunshine and rainfall to storms and temperature fluctuations – directly impact the physical and chemical characteristics of our oceans, lakes, and rivers. Similarly, the geographical landscape, including topography, soil composition, and coastal features, plays a critical role in shaping these aquatic habitats. Consider for a moment the seemingly simple act of rain. Rainfall over land influences river discharge, bringing nutrients and sediments into freshwater and coastal systems. Changes in salinity, turbidity, and nutrient levels can dramatically alter the suitability of these waters for different fish species. Strong winds can drive ocean currents, upwelling events that bring nutrientrich deep waters to the surface, and the dispersal of fish larvae. Extreme weather events like cyclones and floods can cause devastating impacts on both wild and aquaculture-based fisheries. Furthermore, the broader geographical context dictates the regional climate, influencing long-term patterns of water temperature, precipitation, and wind. These climatic conditions, in turn, determine the types of aquatic ecosystems that can thrive in a particular area and the species that inhabit them.5 Understanding these geographical controls is essential for predicting the potential and limitations of fisheries in different regions.

Precipitation is a vital component of the Earth’s water cycle, playing a crucial role in shaping our climate, weather, and ecosystems. It occurs when water vapor in the atmosphere condenses and falls to the ground as rain, snow, sleet, or hail. Precipitation is a key driver of weather patterns, influencing everything from local weather events to global climate trends.
In this chapter, we will explore the various forms of precipitation, including rain, snow, sleet, and hail, and examine the factors that influence their formation and distribution. We will also discuss the importance of precipitation in sustaining life on Earth, from supporting plant growth and agriculture to shaping landscapes and ecosystems. The key topics are:
• Forms of precipitation (rain, snow, sleet, hail)
• Precipitation processes (formation, distribution, intensity)
• Factors influencing precipitation (temperature, humidity, wind patterns)
• Importance of precipitation (ecosystems, agriculture, water resources)
• Precipitation measurement and prediction (methods, challenges, applications)
By understanding precipitation, we can better appreciate the complex interactions between the atmosphere, oceans, and land surfaces that shape our planet’s climate and weather patterns.

14.1.2 How it Works
• Temperature Rise: When the temperature rises, the alcohol in the bulb expands, pushing the mercury up the arm on the maximum temperature side. The mercury pushes the index upwards, and this index stays at the highest point reached as the mercury falls back down with decreasing temperature.
• Temperature Fall: When the temperature falls, the alcohol in the bulb contracts, pulling the mercury down on the minimum temperature side (and thus up on the maximum side). The mercury on the minimum side pushes its index upwards. As the temperature rises again, the mercury retreats, leaving the minimum temperature index at the lowest point reached.
• Reading the Thermometer: To read the maximum temperature, you look at the lower end of the index on the maximum temperature scale. To read the minimum temperature, you look at the lower end of the index on the minimum temperature scale. The current temperature can be read from either side by noting the position of the top of the mercury column.
• Resetting the Thermometer: After taking the readings, the indices need to be reset. This is typically done using a small magnet to pull the steel indices back down to the current level of the mercury.

In an era defined by rapid technological advancements and an ever-changing climate, the need for precise, adaptive, and actionable weather intelligence has never been greater. As global weather patterns become more erratic and extreme events increasingly disrupt lives and livelihoods, the integration of real-time field response into weather intelligence systems represents a transformative opportunity. Just as companies like Google and Tesla leverage real-time user inputs to continuously update their software, refine artificial intelligence (AI) models, and provide timely road-and-traffic guidance, weather intelligence systems that are continuously refined by feedback from farmers, fishermen, and other local stakeholders offer the promise of dynamic, “live” insights that can revolutionize agricultural practices and community resilience (Fig.10.1). This chapter delves into the critical importance of collecting and synthesizing feedback from those who are on the frontlines of weather impacts. It explores the methodologies and benefits of integrating real-time field data into weather intelligence systems, drawing parallels to the iterative processes observed in hightech industries. In doing so, we highlight how these innovations can maximize

1. Introduction
With commercial uses ranging from the production of high-quality substances to the manufacture of pharmaceuticals, hydrogenation is an essential step in the formation of organic compounds (Cerveny et al., 1986). There are two main approaches to hydrogenation: direct hydrogenation, which employs pressurized hydrogen gas, and transfer hydrogenation (TH). A versatile and effective approach for producing a large variety of hydrogenated molecules, the TH method entails adding H2 to molecules via an origin other than H2 gas. This approach is increasingly preferred over direct hydrogenation and has recently attracted considerable interest in hydrogenation research. The benefits of the TH method include (i) the elimination of potentially dangerous pressurized hydrogen gas and the complexity of experimental setups, (ii) the accessibility, cost-effectiveness, and ease of use of hydrogen donors, (iii) the potential to recycle the main byproduct, and (iv) the availability and stability of the catalysts employed (Brieger et al., 1974).
1.1. The Historical Context, Core Principles, and Groundbreaking Research on TH (transfer hydrogenation)
With a history spanning more than a century, the TH reaction has a rich past. In order to enable hydrogen transfer between equivalent donor and acceptor units, Knoevenagel showed in 1903 that palladium black could efficiently aid in the disproportionation of dimethyl 1,4-dihydro terephthalate into dimethyl terephthalate and cis-hexahydroterephthalate. Three primary types of hydrogen transfer reactions were distinguished by Braude and Linstead: (i) the hydrogen movement within a single molecule; (ii) hydrogen disproportionation, which entails transfer among identical donor and acceptor units; and (iii) TH-dehydrogenation, which takes place between distinct donor and acceptor units. Of them, THdehydrogenation— often just called TH—is the most well-known and often applied sector. Meerwein-Ponndorf-Verley (MPV) reductions, early transition metal-catalyzed reactions, organocatalytic processes, enzyme-catalyzed reactions, heat techniques, and base-catalyzed reactions are among the types of TH reactions that are classified according to the type of catalyst used. The historical context, important research, and underlying ideas of each category will be covered in detail in this section.In 1925, Meerwein et al. independently reported the significant MPV reduction, which were the first TH process involving carbonyl groups. After earning his Ph.D. under Richard Anschütz in Bonn, where he was appointed a professor in 1914, Hans Meerwein (1879–1965) moved to Königsberg in 1922 and then to Marburg. His name is associated with a number of processes and reagents,

1. Introduction
Palladium (Pd), which has the atomic number 46, was discovered in 1803 by the English chemist William Hyde Wollaston. It is a well-known transition metal recognized for its versatile catalytic properties in chemical reactions, material sciences, and various industries. The palladium-catalyzed coupling reactions extend beyond the formation of biaryls. Many carbon–carbon, carbon–nitrogen, and carbon–oxygen bond-forming reactions in organic chemistry are facilitated by palladium salts and catalytic systems derived from palladium. Some notable organic reactions that involve palladium include the Mizoroki-Heck reaction, (Biffis et al., 2018, Koranne et al., 2023, Lee et al., 2021) Suzuki-Miyaura coupling, (Zhang et al., 2023) Negishi reaction, (Haas et al., 2016). Stille coupling, (Cordovilla et al., 2015). Sonogashira coupling, (Chinchilla & Najera, 2007) Tsuji-Trost reactions, (Kvasovs et al., 2023). and Wacker catalytic processes. (Zhang et al., 2023) In this chapter, we will focus on the applications of palladium and its salts in C-N bond-forming reactions.
2. Palladium (Pd)-Catalyzed C–N Bond Formation
Besides copper, palladium metal is considered as the most widely used metal in organic synthesis. The discovery of cross-coupling reactions catalyzed by palladium(0) complexes in the 1970s was a highly important achievement that substantially changed the strategy of organic chemistry. Best applications of the palladium salts are in enantiolective and new C-N bond forming reactions. Stephen L. Buchwald and John F. Hartwig opened up the catalytic scope of palladium in newer methodologies on C–N bond forming reactions during 1990s, (Ruiz- Castillo & Buchwald, 2016) and henceforth, new methodologies of carbocycles, heterocycles, and simple organic compounds have been created in large scales (Rayadurgam et al., 2021). The mechanisms of palladium-catalyzed C-N cross-coupling reactions are critically discussed in numerous high-quality research journals with different theoretical and experimentally proven methods (Beletskaya & Averin, 2021). However, the most acceptable mechanistic pathway to reaction products in these Pd-catalyzed reactions involving palladium is illustrated in Scheme 1. The process begins with the formation of a palladium complex through the reaction of an aryl halide (which can be aliphatic, heteroaryl, or functionalized alkenes/alkynes), a palladium salt, and amino nucleophiles. In the presence of a suitable base, the loosely bonded halide or any leaving groups are eliminated, leading to the formation of a palladium (IV) complex. This complex then undergoes reductive elimination, resulting in stable aminated aryl, heteroaryl, alkyl, or functionalized alkenes/ alkynes. Additionally, a more generalized reaction mechanism is presented in a circular pathway format, highlighting the bonding approaches, rearrangements, intermediate formations, and the final release of target compounds, as depicted in Scheme 1. The involvement of higher valence organo-palladium complexes in such catalytic transformations have been well established (Hickman & Sanford, 2012).

Introduction
1.1. Definition and Significance of Natural Products
Natural products are chemical compounds or substances derived from living organisms in nature. These diverse sources, including plants, animals, fungi, and microorganisms, produce a wide range of chemical structures and functions. The significance of natural products lies in their diverse biological activities and potential applications in therapeutics, agriculture, and various industries. Natural products have been used for centuries in traditional medicine and continue to serve as the foundation for many modern pharmaceuticals, providing templates for the development of synthetic analogues and novel drugs. Their complexity and unique structural features often translate into high biological activity, making them valuable in the discovery of new therapeutic agents. Furthermore, natural products are generally perceived as safer and more environmentally friendly compared to synthetic chemicals, contributing to their appeal in numerous applications.
1.2. Historical Perspective on the Use of Natural Products
The use of natural substances has a long history, with evidence of their application in ancient civilizations such as Egypt, China, India, and Greece. Traditional medical systems, including Ayurveda, Traditional Chinese Medicine, and Indigenous practices, have utilized plants, animals, and minerals to treat various ailments. These early practices laid the foundation for the systematic investigation of natural products and their medicinal potential. One of the earliest documented uses of natural products in medicine is the Ebers Papyrus, an ancient Egyptian text from around 1550 BCE (Packard, 1931). Similarly, ancient Indian texts, such as the Charaka Samhita and the Sushruta Samhita, describe the use of plant-based medicines in Ayurvedic tradition. The scientific investigation of natural products gained momentum in the 19th century, with the isolation of pure compounds, including morphine, quinine, and penicillin.
1.3. Current Trends and Applications
Natural products are invaluable in various industries, serving as a rich source of bioactive compounds for drug development, sustainable agriculture, and functional food products. Many modern medicines, such as the anticancer drug paclitaxel and the antimalarial artemisinin, are derived from natural sources. These naturally-derived compounds often possess unique structures and mechanisms of action that are difficult to replicate synthetically.

The climate crisis has emerged as one of the most pressing issues of our time, threatening the very foundations of our planet and its inhabitants. The scientific consensus is clear: human activities, particularly the emission of greenhouse gases, are significantly contributing to the rising global temperatures, devastating natural disasters, and unpredictable weather patterns. As the world grapples with the challenges posed by climate change, a critical question arises: is it a compromise or a compulsion to act? The climate crisis is a complex and multifaceted issue, requiring a comprehensive and collective response. On one hand, there are those who advocate for a compromise, suggesting that economic growth and development can be balanced with environmental concerns (Fig. 2.1). This approach emphasizes the need for gradual and incremental changes, allowing countries and industries to adapt to new regulations and technologies. Proponents of this view argue that a compromise is necessary to avoid economic disruption, ensure energy security, and promote international cooperation. Fig. 2.1. Eco-evolutionary feedback by carbon cycling traits, in response to climate change On the other hand, there are those who insist that the climate crisis demands a compulsion to act, requiring immediate, drastic, and collective action. This perspective emphasizes the urgent need to reduce greenhouse gas emissions, transition to renewable energy sources, and protect vulnerable communities from the impacts of climate change. Advocates of this view argue that the window for action is rapidly closing, and that anything less than a concerted and emergency response will condemn future generations to a catastrophic and unlivable world. The science unequivocally supports the latter perspective. The Intergovernmental Panel on Climate Change (IPCC) has warned that in order to limit global warming to 1.5°C above pre-industrial levels, global carbon emissions must reach net-zero by 2050. This requires a 45% reduction in emissions by 2030, and a complete phase-out of fossil fuels by 2050. The consequences of inaction are stark: more frequent and intense natural disasters, sea-level rise, water scarcity, food insecurity, and mass migration (Fig. 2.1).

Introduction 
Fossil fuel consumption is associated with a number of grave problems, including economic distress and increased greenhouse gas emissions that cause global warming. The world’s population and environment are deeply concerned about these issues, which are a result of rising greenhouse gas emissions and the depletion of fossil fuels. Furthermore, there has been much discussion about the effects of relying so heavily on petroleum-derived fuels on the environment, the economy, and energy efficiency [1]. According, high process costs, inadequate infrastructure, and other technological challenges impede the manufacturing of second- and third-generation biofuels [2]. The main role of enzymes and other microorganisms during fermentation is as a catalyst to speed up the process of turning saccharides into alcohol. In this kind of biofuel production, lignocellulosic and algal material make up the majority of the biomass used to produce ethanol. The biochemical variety of microalgae is employed in numerous biotechnological and commercial applications [3]. The use of non-usable biomass has been enhanced with each new generation, which lowers production costs and speeds up the manufacture of biofuels. A wide variety of biofuels, such as biogas, bioethanol, biohydrogen, and biodiesel, can now be produced thanks to the application of nanotechnology. In order to convert triglycerides into biofuels, two important chemical events must occur: trans-esterification and esterification [4]. The majority of the nano-catalysts needed to produce biofuel come from microbial fuel cells. Nanoparticles, nanosheets, and nanotubes are examples of these nanocatalysts [5]. The utilization of nanotechnology in the biofuel production process holds promise for enhancing the effectiveness of current procedures. Compared to the production of biofuels, the synthesis of nanoparticles is much more interesting due to the potential applications, challenges, and opportunities that it presents [6]. Here, we review the literature on the application of nanotechnology to improve bioenergy production from algae processing. The different kinds of nanoparticles, including metallic, magnetic, metal oxide-based, and carbon nanotubes that are utilised in the production of bioethanol and biodiesel are covered on this page. A focus is placed on the application of these nanomaterials and how they affect the extraction and transesterification of lipids [7]. This chapter makes the connection between the advancement of nanotechnology and its contribution to the creation of a more efficient and sustainable technique for processing algal biomass to produce bioenergy.

Drug distribution
Drug distribution refers to the process of ensuring that pharmaceutical products, including controlled substances like narcotics, reach healthcare providers, pharmacies, and patients efficiently, safely, and legally. A well-organized drug distribution system ensures product quality, timely availability, and compliance with regulatory standards. Given the sensitivity around narcotics, their distribution requires enhanced monitoring to prevent diversion and misuse.
Definitions
In-Patient Distribution
This refers to the process of delivering medications to patients who are admitted to a hospital or healthcare facility. Medications are typically managed by pharmacists who ensure that patients receive the correct drugs based on their treatment plans.
Out-Patient Distribution
This involves dispensing medications to patients who are not admitted to a healthcare facility. Patients receive their prescriptions from outpatient pharmacies or clinics.
Individual Prescription Order Method
The individual prescription order method involves preparing medications separately for each patient based on a physician’s prescription. The pharmacy receives the prescription and dispenses a specific amount of medicine for the prescribed duration. This method is used in both in-patient and out-patient settings, though it is more common in the latter.

Water Quality Parameters
Irrigation water contains impurities in varying concentration. The suitability of irrigation water mainly depends up on the amount and type of salts present in the water. The main soluble constituents are calcium, magnesium, sodium as cations and chloride, sulphate, bicarbonates as anions. The other ions present in minute quantities are boron, selenium, molybdenum and fluorine which are harmful to animals fed on plants grown with excess of these ions.
Quality of irrigation water is judged with three parameters
1. Total salt concentration
2. Sodium absorption
3. Bicarbonate and boron content.
Total Salt Concentration
Salt content of irrigation water is measured as electrical conductivity (EC). Conventionally, water containing total dissolved salts to the extent of more than 1.5m mhos /cm has been classified as saline. Saline waters are those which have sodium chloride as predominant salt. Brackish water is one that is contaminated with acid, bases, salts or organic matter, whereas saline water contains mainly dissolved salts, Based on EC irrigation water is classified as below.

Importance of virtual water in agriculture
Virtual water is with the meaning of the concept when water embedded in goods and services and is exchangeable from one country to a different. The country is under water-scarce; the water that’s ‘saved’ is often used towards other ends. Water-scarce countries (like Israel) discourage the export of relatively water-intensive crops (like orange, water melon) precisely to stop large quantities of water from being exported to different parts of the earth. In recent years, the concept of virtual water on trade has gained weight both within the scientific also as restricted by the political debate. The notion of the concept is ambiguous. It changes between an analytical, descriptive concept and a political induced strategy. As an analytical concept, virtual water trade represents an instrument that permits the identification and assessment of policy options not only within the scientific but also within the political discourse. As a politically induced strategy, the question of virtual water trade are often implemented during a sustainable way, whether the implementation are often managed during a social, economical, and ecological fashion, and that countries the concept offers a meaningful option. the info that underlie the concept of virtual water can readily be wont to construct water satellite accounts and brought into economic models of international trade like the Computable General Equilibrium of Global Trade Analysis Project such a model are frequently wont to study the economic implications of changes within the water system or water policy, also because the water resource implications of economic development and trade liberalization. The data pertaining to virtual water is product of GTAP.
Keywords: Virtual water; foodstuff and food; water content in different food materials; water deficit areas;

Introduction 
The increase in the concern over the climatic changes as well as the dwindling fossil fuels reserves have intensified the search for the sustainable energy sources. The algal biofuels garnered the attention because of their fastest growth rates, as well as their capability to grow in a non-arable land, higher lipid content, as well as the capability to absorb the CO2. Therefore, the larger scale implementation of the algal biofuels can face a lot of environmental, economic, as well as the technological challenges which needs further investigations (1). One of the current green energy and renewable alternative answers to the world’s current energy problems is the development of algal biofuel (2). Because algae biofuels are environmentally beneficial, they have been seen as a clean energy source (3). An integrated biorefinery strategy could be applied to bio transform algal biomass into many biofuels, including bioethanol, biobutanol, biogas, biohydrogen, and biodiesel, in order to fulfil the energy requirement. Nonetheless, a lot of an obstacles stand in the way of the development, manufacturing, as well as use of microalgal biomass technology. (4). These problems include the creation of affordable microalgal production systems, efficient microalgal growth systems, effective microalgal harvesting techniques that save energy, effective microalgal extraction methods, and economical and environmentally friendly microalgal conversion procedures. Many microalgal technologies are examined in this chapter, along with their applications, difficulties, case studies, and prospects. (5). Algae are appealing feedstock sources for the manufacturing of biofuels. Algae may be applicable to produce important goods like as nutraceuticals, biodiesel, biogas, as well as bioethanol (6). Biofuels are benign to the environment, renewable, and biodegradable. Algae are very valuable because of their higher lipid content as well as fast development. The largest class of algae, known as chlorophytes, includes both macro- and microalgae and is used in bioremediation, the water treatment, the food production, the medicine, as well as the energy production. We discussed many techniques for planting, harvesting, and processing in this chapter. The selection of high lipidcontaining algae strains, commercial harvesting, high infrastructure, operation, and maintenance expenses, and water evaporation problems seem to be the main obstacles. It will take creative and effective methods to make the manufacturing of algae-based biofuels desirable. Increasing the production of biofuels will contribute to the preservation of natural resources, which will protect the environment (7).

1. Introduction:- Ensuring Quality and Success in Assisted Reproductive
Technology through Good Laboratory Practices Assisted Reproductive Technology (ART) in animals has become an increasingly vital set of techniques with wide-ranging applications across agriculture, wildlife conservation, and biomedical research. These technologies, encompassing procedures such as in-vitro fertilization (IVF), embryo transfer, and cryopreservation of gametes and embryos, offer solutions to infertility, enable genetic improvement in livestock, and play a crucial role in preserving endangered species. As the application of ART expands throughout the globe, the need for stringent quality control and standardization becomes paramount to ensure the reliability and reproducibility of outcomes. Good Laboratory Practices (GLP) represent a well-established quality system that provides a framework for the organizational processes and conditions under which non-clinical studies are planned, performed, monitored, recorded, reported, and archived. Originally developed to ensure the integrity of safety data for pharmaceuticals and other regulated products, the fundamental principles of GLP are highly relevant to the field of animal ART. This report aims to explore the application of GLP in ART and to thoroughly investigate its contribution to achieving successful outcomes in various ART procedures and across different animal species. By examining the core principles of GLP and their practical implementation in animal ART laboratories, this analysis will highlight the critical role of standardized practices in enhancing the reliability, ethical conduct, and overall success of animal reproductive technologies.
2. Good Laboratory Practices (GLP) in Reference to ART
Good Laboratory Practices are broadly defined as a quality system that governs the organization and conditions under which non-clinical health and environmental safety studies are planned, performed, monitored, recorded, reported, and archived. This system is designed to ensure the quality and

Introduction
India with a population of 1.30 billion people is highly focusing on “Development”i.e. good food, better health & living conditions for everyone. With the increase in the incomes, people can now afford better nutrition in the form of poultry egg and meat, now poultry industry has transformed from a mere backyard activity into a major commercial activity in just four decades. India is now the world’s 3rd largest egg producer and the 5thlargest producer of broilers. The Indian poultry market witnessed an increasing trend over the past five years, growing at a Compound Annual Growth Rate (CAGR) of 8.6% (DAHD, 2023). Poultry sector in India is valued at about Rs. 1,50,000 crore (2022-23) broadly divided into two sub-sectors – one with a highly organized commercial sector with about 80% of the total market share (say, Rs. 1,20,000 crore) and the other being unorganized with about 20% of the total market share of Rs. 30,000 Crore. (DAHD, 2023). Poultry production in India has become a profitable and most popular income generating sector for the educated unemployed youth. Most of the poultry farmers are interested in broiler production due to its quick returns, less space requirement and higher weight gains. The productive potential of poultry in India has not been fully exploited due to deficit feed resources and unutilization of available improved technologies for getting high productivity from the poultry at economical rate. Hence, it is essential to further enhance the feeding value of available feed resources so as to improve the efficiency of feed utilization and minimize the cost of feed per kilogram live weight gain. The use of antibioticas growth promoters in poultry has been banned due to concern about their residues in tissue and induction of bacterial resistance. Due to these concerns, recently many feed additives has been investigated for alternatives tofeed antibiotics. The international feed industry is facing the challenge of the awareness among the consumers of meat on the risk of bringing about antibiotic resistance in pathogenic microbiota through antibiotics used in animal and poultry feeds. It has directed them towards the non-antibiotic feed additives. Among them, the feed additives of plant origin, called as Phyto-additives or Phytogenic Feed Additives (PFA) or Phytobiotics are considered to be a better alternative as non-antibiotic growth promoters, even though there are well established non antibiotic growth promoters such as organic acids and probiotics. The Phytogenic feed additives also vary widely in their botanical origin, processing and composition. They have been used in solid, dried and ground forms or as extracts or essential oils.It is reported that aromatic plants may increase feed intake and may improve secretion of endogenous digestive enzymes. It has been shown thatthe dietary incorporation of herbs may provide beneficial effect on poultry performance and health due to the antimicrobial activity of their phytochemical components. Phytobiotics have gained increasing interest as natural growth promoting feed additives in broiler production in recent years. These have wide range of medicinal properties with no residual side effects and are best alternatives to antibiotic growth promoters (Chaudhary et al., 2018, 2019, Rahman et al., 2014). Beneficial effects of these substances in poultry nutrition are due to their high content of pharmacologically active compounds stimulating appetite and feed intake, improving endogenous digestive secretion and activating immune responses (Nouzarian et al., 2011 and Toghyani et al., 2010).

Chapter 6 delves into the critical role of monsoon rainfall in shaping the economies and lives of numerous countries across the globe. While the concept of a country being only dependent on monsoons is a simplification, this chapter focuses on regions where the seasonal monsoon rains are the paramount source of freshwater for agriculture, industry, and daily life. These monsoon-dependent nations, predominantly located in South Asia, Southeast Asia, Australia, parts of Africa, and even areas of South America, experience a dramatic annual cycle of wet and dry periods dictated by the shifting monsoon winds. The arrival and intensity of the monsoon rains are not merely meteorological events; they are pivotal determinants of agricultural yields, food security, economic stability, and the overall well-being of billions of people. Given this profound dependence, accurate and timely forecasting of monsoon rainfall is of paramount importance. The second part of this chapter explores the current state of the art in monsoon forecasting. We will examine the sophisticated methodologies and technologies employed by meteorological agencies and research institutions worldwide to predict the onset, duration, intensity, and spatial distribution of monsoon rains. This includes an overview of empirical models leveraging historical climate data, the increasing reliance on complex dynamical models that simulate atmospheric and oceanic processes, and the integration of advanced statistical techniques like Bayesian methods and downscaling to enhance forecast accuracy and regional specificity. Understanding the strengths and limitations of these cutting-edge forecasting techniques is crucial for effective water resource management, agricultural planning, disaster preparedness, and ultimately, for building resilience in monsoon-dependent regions.

Real-time crop monitoring for efficient climate guidance extends beyond monsoon-dependent regions and holds significant importance in a global agricultural context. While the fundamental technologies and principles remain similar, the specific applications and benefits are tailored to the diverse agricultural systems and climates worldwide.
10.1. Global Applicability Across Diverse Agricultural Systems
• Rain-fed Agriculture (Beyond Monsoons): In semi-arid and arid regions globally, where rainfall is scarce and unpredictable, real-time monitoring of soil moisture and plant stress through remote sensing and ground sensors is crucial for optimizing the limited water resources and implementing drought management strategies (Fig.10.1).
• Irrigated Agriculture: Even in systems relying on irrigation, real-time monitoring helps optimize water usage based on actual crop needs and prevailing weather conditions, preventing over-irrigation and conserving water, a critical resource globally.
• Temperate and High-Latitude Agriculture: In these regions, real-time monitoring can track temperature fluctuations, frost risks (as you researched previously), and the impact of shorter growing seasons on crop development, allowing for timely interventions like frost protection or adjustments to planting schedules.
• Tropical Agriculture: Beyond monsoons, tropical regions often face challenges like high humidity and pest/disease pressure. Real-time monitoring of leaf wetness and other microclimate factors aids in targeted pest and disease management, reducing the need for broad-spectrum applications.

As global climate change becomes an increasingly urgent concern, the search for sustainable and renewable energy sources has intensified. Among the alternatives to fossil fuels, biofuels have emerged as a promising solution due to their potential to reduce greenhouse gas emissions and dependence on petroleum. Biofuels are derived from organic matter, such as crops, agricultural residues and other biomass, which can be converted into energy sources like ethanol, biodiesel, and biogas. For instance, crops like corn and soybeans contain oil extracts that can be processed into biofuels, offering a renewable and environmentally friendly alternative to traditional fossil fuels (Demirbas, 2009). However, the potential of biofuels extends beyond these conventional sources, as researchers explore a wide range of organic materials that can be sustainably regrown and harvested, minimizing ecological impacts (Naik et al., 2010). Biofuels have gained significant importance in both developed and developing economies, driven by their potential to enhance energy security and reduce carbon footprints. In 2023, the United States led global biofuel production with 15,550 million gallons, followed by Brazil with 8,260 million gallons. India ranked third, producing 1,430 million gallons of bioethanol and achieving an E11.7 blend rate during the 2022–2023 period. This blend was sourced from various feedstocks, including sugarcane juice (5%), cane molasses (5%), and damaged food grains (DFG) (1.7%). Historically, India’s ethanol production has relied heavily on sugarcane molasses, but the National Biofuel Policy (NBP) of 2018 has been instrumental in promoting the use of biofuels to reduce fossil fuel dependence, mitigate greenhouse gas emissions, and strengthen energy security (Ministry of Petroleum and Natural Gas, 2018). India, the third-largest energy-consuming nation globally, faces considerable challenges due to its heavy dependence on imported oil, posing risks to both economic stability and strategic security. With its share of global energy consumption projected to double by 2050, the country is actively seeking domestic alternatives to curb this reliance. Ethanol, produced within India, has emerged as a viable substitute. Since its initial pilot in 2001, ethanol-blended petrol has demonstrated notable environmental advantages, with every 10 million liters reducing CO2 emissions by 8,000–17,000 tonnes compared to conventional

Introduction 
Maize (Zea mays L.) which belongs to the Poaceae family, has its roots in the American continent where it was once grown by ancient cultures like the Indians, Magyars, and Aztecs. Today, maize is one of the most widely cultivated crops globally, with the largest productions in countries such as the US, China, India, and Brazil. As a monocotyledonous and cross-pollinated annual plant, maize is an angiosperm with seeds enclosed in a fruit or shell. The root system of maize is fibrous, reaching up to 60 cm. in soil depth. Maize is a warm-season crop with specific agro climatic requirements for successful cultivation. It thrives in warm temperatures and requires a minimum temperature of around 10°C (50°F) for germination. The ideal temperature range for its growth is between 20°C and 30°C (68°F to 86°F). However, maize is sensitive to frost, and exposure to freezing temperatures can damage or kill the crop. Adequate and well-distributed rainfall is crucial during its growing season, as maize needs about 500 to 1000 mm. (20 to 40 inches) of rainfall to support its development, with higher water requirements during flowering and grain-filling stages. While the crop is moderately droughttolerant, moisture stress at critical growth stages can significantly impact yield. Maize is a sun-loving crop and requires long daylight hours with ample sunshine for efficient photosynthesis and plant growth. The soil should be well-drained, loamy or sandy, rich in organic matter, and have a pH ranging from 5.8 to 7.0 (Greaves et al., 1996). Avoiding waterlogged or compacted soils is crucial, as they can impede root development and nutrient uptake. Maize can be cultivated at varying altitudes, but its suitability is generally limited to elevations below 2,500 meters (8,200 feet) above sea level. The crop typically requires 90 to 120 days from planting to maturity, although some varieties with shorter growing seasons are available for regions with limited frost-free periods. High salinity can result in decreased plant leaves, green weight, fresh weight, shorter shoots, and root length but salt-tolerant varieties have been developed.

Introduction 
Sorghum bicolor L. Moench, commonly known as sorghum, has emerged as a significant and promising candidate for both sugar and lignocellulosic biofuel production. Cultivated sorghum varieties exhibit a wide range of phenotypic and morphological characteristics, and based on their intended use, they have been categorized into four distinct groups: grain, forage, energy, and sweet sorghum. Grain sorghum varieties typically stand between three to six feet in height, featuring large ear heads. Their primary role is to serve as a source of food for humans or livestock feed. These varieties play a crucial role in providing sustenance and nutrition to both people and animals. Sweet sorghum, also known as sweet stalk sorghum, represents a unique group of genotypes that accumulate soluble sugars within their stalks. These varieties can grow impressively tall, reaching up to twenty feet, and produce significantly higher biomass yields compared to grain sorghum (Murray et al., 2009). Sweet sorghum’s stems are characterized by their thickness and fleshiness, although they do tend to have relatively lower seed yields. Despite this, sweet sorghum offers substantial advantages in terms of bioethanol production due to the high sucrose content present in its stalks (Srinivasa Rao et al. 2009). It has garnered recognition as an ideal candidate for bioenergy crop cultivation in tropical and temperate regions around the world, particularly in the southern United States. When compared to other bioenergy crops such as corn, wheat, sugarcane, sugar beet, cassava, and sweet potatoes, sweet sorghum presents several noteworthy benefits (Disasa et al., 2016). It is notably drought-tolerant and requires significantly less water than many other crops, such as one-third of the water needed for sugarcane and half of that required for corn. Furthermore, it exhibits tolerance to salinity, enabling its cultivation in marginal regions that are not traditionally suitable for crop production. Additionally, sweet sorghum boasts lower greenhouse gas emissions on a life-cycle basis, contributing to a more sustainable and environmentally friendly biofuel production process. The applications of sweet sorghum are diverse, with its stalks being used for various purposes. In Brazil and India, the stalk is chewed fresh or processed for the production of food-grade syrup and alcohol. Its high sucrose content makes it an excellent candidate for bioethanol production, with the potential to yield up to 8,000 liters per hectare, surpassing the ethanol yield of corn by approximately twofold and outperforming

Fourth-generation biofuels, also known as advanced liquid biofuels, represent a progression of biofuel production leveraging advanced technologies (Chiaramonti & Maniatis, 2020). They incorporate the concept of “carbon capture and storage (CCS)” at both the feedstock and processing levels. Utilizing non-competitive feedstocks like algal biomass, cellulosic materials, and genetically engineered microorganisms, 4G biofuels ensure renewable and sustainable production without relying on arable land or food crops. The feedstock is designed not only to enhance processing efficiency but also to capture more carbon dioxide as the crop grows. Thermochemical processing methods are coupled with CCS technologies, which direct the generated carbon dioxide into geological formations or storage areas such as depleted oil fields or mineral storage as carbonates (International Renewable Energy Agency [IRENA], 2021). Fourth-generation biofuels have the potential to significantly reduce greenhouse gas (GHG) emissions and can even achieve carbon neutrality or negativity compared to previous generations of biofuels. This concept aligns with the idea of “Bioenergy with Carbon Storage (BECS)” (Demirbas, 2010). These advanced biofuels are currently in the development and experimental stages, encompassing various applications related to technology, processing, and feedstock. The primary feedstock for fourth-generation biofuels production consists of genetically engineered high-yielding biomass with low lignin and cellulose contents, addressing the challenges encountered in second-generation biofuels production. Alternatively, metabolically engineered crop plants with lower lignin, high oil contents facilitate enhanced carbon capture capabilities, and improved cultivation, harvesting, and fermentation processes and can significantly enhance biofuels production (Dutta et al., 2014).

Microalgae have long been recognized as good potential sources for biofuel production due to their relatively high oil content and rapid biomass production (Schenk et al., 2008; Hu et al., 2008). These photosynthetic organisms thrive in a variety of aquatic habitats, including lakes, rivers, oceans, and even sewage, demonstrating their adaptability to diverse environmental conditions. They can tolerate a wide range of temperatures, salinities, and pH levels, as well as varying light intensities and aquatic or desert conditions. Additionally, microalgae can grow independently or in symbiosis with other organisms, making them highly versatile for various cultivation systems (Mutanda et al., 2011). Algae are generally grouped into three major categories: Rhodophyta (red algae), Phaeophyta (brown algae), and Chlorophyta (green algae), and are further classified by size into macroalgae and microalgae. Macroalgae are large, multicellular organisms visible to the naked eye, while microalgae consist of microscopic single cells that can be either prokaryotic, similar to cyanobacteria, or eukaryotic, similar to green algae (Fields et al., 2014; Maltsev & Maltseva, 2021). Microalgae are capable of producing a wide array of valuable bioproducts, including polysaccharides, lipids, pigments, proteins, vitamins, bioactive compounds, and antioxidants. They grow at a much faster rate compared to terrestrial crops and can be cultivated on non-agricultural land using non-potable saltwater or wastewater, reducing competition with food crops and ensuring sustainability (Lee et al., 2014). This has made microalgae an increasingly attractive alternative feedstock for biodiesel production, which relies heavily on the high lipid content of microalgae. The majority of these lipids are stored in the form of triacylglycerols, a type of oil that is ideal for biodiesel production. Beyond biodiesel, microalgae can also be utilized in various other energy production pathways. Some microalgal strains can produce hydrogen gas under specific growth conditions, while algal biomass can be combusted like wood or digested anaerobically to produce methane biogas, which can be used for heat and power generation. Additionally, algal biomass can be processed into crude bio-oil through pyrolysis, further expanding its applications as a renewable energy source (Mumtaz et al., 2019).

14.1 Introduction
The other topics of the metal forming are as listed below.
a. Stretch forming operation
b. Formability of sheet metal
c. Test methods
These topics are presented in this chapter.
14.2 Stretch Forming Operation
A sheet metal is simultaneously stretched and curved over a die during the stretch forming process to create big shaped parts. Stretch forming is done using a stretch press, where jaws are gripped firmly to fix a sheet metal along its edges. To stretch the sheet, the grasping jaws are individually coupled to a carriage that is drawn by a hydraulic or pneumatic force. A stretch form block, also known as a form die, is the tooling utilized in this procedure. It is a solid contoured piece that the sheet metal will be pressed against. The most common type of stretch press is vertically orientated with the form die situated on a press table , which will be elevated by a hydraulic ram into the sheet. Tensile stresses build and the sheet plastically deforms into a new shape when the form die is pressed into the firmly gripped sheet. The sheet is pulled horizontally around the form die by the gripping jaws of a horizontal stretch press, which mounts the form die sideways on a stationary press table

Introduction 
Sustainable development is one of the most important concepts in a business organization. In order to satisfy all the needs of the present without compromising the ability of future generations to meet their own requirements, sustainable development is a comprehensive strategy to growth. In order to build a stable and equitable future, it incorporates social inclusion, economic progress, and environmental conservation. The “three pillars” or “three dimensions” of sustainability—economic, social, and environmental—are frequently used to frame the idea of sustainable development. The North East Indian state of Assam’s cultural and economical legacy has an intricate connection to the long and prosperous past of the Assam Silk Industry. From the very ancient times, the production of silk from silkworm and weaving into beautiful garments can be seen in this part of the region.Evidence indicates that the cultivation of silk and weaving were well established in the region by the first millennium BCE, incorporating thousands of years to the cultural heritage of silk weaving in Assam.The indigenous communities of Assam, particularly the Bodo-Kacharis, have been identified for spreading sericulture to the area. Assam produces three types of silk, namely Muga Silk which is also termed as Golden Muga, Pat Silk and Eri or Endi Silk. Also known as the “Golden Silk”, Muga Silk is unique only to Assam and hugely popular because of its natural sheen which increases with each wash. The silk is produced by a special silkworm Antheraea assamensiswhich is endemic to Assam. The town of Sualkuchi, in the Kamrup district of Assam, India, is home to the well-known traditional silk-weaving industry. Sualkuchi, dubbed the “Manchester of Assam,” is well-known for its superior silk goods, especially those crafted from Assamese-only Muga, Eri, and Pat silk(Ghosh, 2021; (Rajesh et al., 2020) The Assam Silk is considered as one of the finest in regional, national and international market because of its superior quality, bright colors and attractive designs. It has a good amount of potential to boost the economic development of Assam. Despite having such importance, it has been observed that the silk industry is facing a lot of problems which is causing a major setback in its growth. The Silk Industry of Assam is highly unorganized because there are less or no educated laborers which results in shortage of agricultural laborers ultimately leading to production shortage. The Assam silk industry, known for producing exquisite silk varieties like Muga, Eri, and Pat silk, faces several marketing challenges that hinder its growth and global competitiveness. Despite being geographically unique particularly Muga Silk, its brand identity is not widely recognized in outside the market. Its reach is restricted to premium and high-end fashion markets due to this lack of worldwide awareness. The majority of Assam’s silk output is limited to local and regional markets. The industry’s minimal web presence and inadequate marketing infrastructure make it difficult for it to penetrate larger domestic and international markets. Silk from Assam is not sufficiently promoted in international forums. There are government initiatives; however, there is a lack of consistency and broad audience reach in marketing activities. In marketplaces where there is competition, this causes the silk to be less visible.Producing Assam silk, particularly Muga silk, requires a lot of work and money. The final product’s high cost of manufacture restricts its customer base to a premium market niche. This lowers total sales and narrows the target market.

Performance metrics and indicators
Traditionally, in the past, TTOs’ performance was measured in monetary terms, such as universities’ revenues derived through commercialization. The methodology, however, is prone to shortcomings, in light of the fact that various TTOs do not receive significant amounts of financial proceeds through their technology transfers. In addition, relying on income does not depict a TTO’s true potential, in light of the fact that it does not account for the total range of outputs of research and commercialization opportunities. Recognizing these limitations, academics have found innovative ways to measure TTO efficiency, such as monetary and non-monetary indicators. Financial indicators typically entail measurable outcomes such as number of signed licenses, income from licenses, royalties collected, equity income, and number of spin-offs or startups created. These are actual gauges of the economic returns from commercialization efforts, and in the majority of instances are used in the context of benchmarking the performance of a TTO in a comparative context, perhaps against peer institutions or industry averages. Non-financial indicators consist of royalty distributions to academics, having an integral role in encouraging academics to participate in commercialisation activity. By incorporating monetary and non-financial metrics, universities might have an enhanced, comprehensive evaluation system for their TTOs. Such evaluation is sure to ensure assessment extends beyond short-run monetary metrics and looks to incorporate several organization, institutional, and research-oriented determinants in driving successful technology transfer.

Introduction
In India acid soils occur in the high rainfall areas covering about 25 million hectares of land with a pH below 5.5 and 23 million hectares of land with a pH between 5.6 and 6.5. In India, acid soils occur in Assam, Meghalaya, Arunachal Pradesh, Mizoram, Nagaland, NEFA, Manipur, Tripura, West Bengal, Bihar, Uttar Pradesh, Himachal Pradesh, Jammu and Kashmir, MP, Maharashtra, Kerala, Karnataka, Tamil Nadu and Andhra Pradesh. Punjab, Haryana, Rajasthan and Gujarat are the only states in India where acid soils do not occur. Soil acidity is a limiting factor affecting the growth and yield of many crops all over the world. The basic problems concerning chemical properties of more acid soils are, besides acidity itself, the presence of toxic compounds and elements, such as soluble forms of Al, Fe and Mn, nitrites and various toxic organic acids. Aluminium (Al) toxicity is one of the major constraints on crop productivity on acid soils, which occur on up to 40% of the arable lands of the world. Al is the third most abundant element in the earth’s crust and is toxic to plants when solubilised into soil solution at acidic pH values. Very few plants can grow well in strong acid soils. Soil acidity below pH value 5.5 is generally injurious to plants. Plant roots are badly affected if the pH value exceeds limits of tolerance for particular crops. High degree of soil acidity (pH 5.0 to 6.5) decreases the availability of plant nutrients particularly phosphorus, calcium, magnesium, molybdenum, iron, manganese, potassium sulphur nitrogen, boron, copper and zinc. It also affects adversely the important microbiological processes, such as nitrogen fixation by Azotobacter, Clostridium and nodule inhabiting bacteria (Rhizobia) of leguminous plants

Irrigation status at the national level
Out of the 140 m ha of net sown area in the country, 50 m ha ia under irrigation working out to a percentage of about 35. In the different states, the net irrigation per cent varies from 12 in Mizoram to as high as 90 in Punjab. Though at national level the contribution from canal and under ground water are almost equal, yet in Assam, Himachal Pradesh, Orissa and the other North eastern states, it is predominantly canal system, while in Gujarat , Punjab, Rajasthan and Uttar Pradesh and ground water predominates as the source. In Tamil Nadu, tank irrigation is an important irrigation source with almost Quarter of the irrigated area under this system. In the other southern states as well as in Orissa also tank system is in vogue to a considerable extent. The unscientific water use in both canal and lift irrigated commands has resulted in raising water table in the first case and fast receding ground water table in the second case. Thus, there is an imminent need for reducing the irrigation water application in agriculture with out affecting the yield and there by increasing the Water Use Efficiency (WUE) The options for increasing the water productivity/improve the WUE are discussed here.
Prevention of water losses in transportation system
Huge quantity of water is lost during the transportation of water from the source (reservoir/main canal! tank/ wells) to the field and till it reaches the root zone. Hardly 20 to 40 per cent of the water released reaches the root zone. The irrigation efficiency can be increased by the selection of proper method of irrigation along with proper design. Apart from the high evaporative and seepage losses occurring at the reservoirs and main canal, considerable amount of water is lost as seepage and evaporation in minors, distributaries, field channel etc. The losses occurring in a typical project in the alluvial plains as reported by the Second Irrigation Commission is given in table 2.

Introduction
Wide range of industrially important products such as antibiotics, vitamins, enzymes, polymers, amino acids, biofuels are produced by microbes in extremely small quantities. Using microbial strains that generate an elevated amount of the intended product is a prerequisite for effective biotechnological procedures at the industrial scale. But since this isn’t an intrinsic feature of the chosen microorganism, changes to their genetic makeup may help to navigate this. Therefore, in order to overproduce the target metabolite and increase process efficiency, industrially relevant microorganisms are exposed to a range of treatments employing physical, chemical, or genetic methods. Thus, microbial strain improvement is the process of improving the biosynthetic capacities of microorganisms to generate the desired product in greater quantities.
Recycling resources and promoting sustainable development have grown in importance in recent years. Cosmetics, food, fuels, lubricants, plastics, drinks, fibres, and medications are just a few of the goods that are being biosynthesised due to the growing popularity of biological production of commercially significant metabolites (Kaur et al., 2012). The rising bioeconomy’s success hinges on our capacity to produce high-performing strains efficiently and economically. One successful strain engineering strategy is the Design–Build– Test–Learn (DBTL) framework. The strain engineering process must be viewed from the perspective of optimising the entire cycle rather than just increasing productivity at each stage, if strain development time and cost is to drastically cut down. We suggest a strategy that incorporates all four phases of the DBTL cycle and leverages the latest developments in phenotyping techniques, high-throughput genome engineering, computational design, and machine learning tools to forecast strain scale-up efficiency. By substituting sustainable alternatives made from renewable feedstock for petroleum-based products and ingredients derived from animals or wild-harvested plants, microbial biomanufacturing of chemicals, materials and biomolecules promises to lower greenhouse gas emissions, enhance land use and promote sustainability. But doing so necessitates creating reliable and effective industrial strains that can generate a variety of goods at reasonable costs. Enhancing the effectiveness of the strain engineering process is necessary to lower development cost, time in order to take advantage of market potential in all bioeconomy industries.
Over the past few decades, technical advancements in genome engineering have significantly boosted our capacity to engineer biological systems. The strain engineering process has been significantly sped and enhanced by synthetic biology methods like as genome editing using CRISPR (clustered

Introduction
The eco-friendly and commercially sustainable production has been a crucial aspect of modern commercial development. The ecologically sustainable microbial production of value-added products has seen rapid growth across multiple sectors, such as food, pharmaceuticals, and energy, resulting in notable economic benefits and social advancements on a global scale (Shi et al., 2022). The development of “omics” technologies has aided the improvement of microbial production processes through diverse omics procedures, such as genomics, transcriptomics, metabolomics, and systems biology (Amer and Baidoo, 2021). These omics approaches give important understandings into the widespread metabolic variations, thereby identifying the factors that affect microbial production efficiency and improving the understanding of targeted optimization strategies. The integration of omics approaches is considered essential for any strategies that aim to be industrially sustainable. Industrial activities depend on the cultivation and accessibility of significantly competent microbial species to optimize bioproduct yields (Keasling, 2012). Recent progress in the industrial generation of value-added products heavily depends on strategies rooted in omics. Typically, the industry can achieve cost-effective production of limited quantities of biopharmaceuticals (Harris et al., 2015). Nevertheless, to sustainably scale up production capacities, economically feasible alternatives must be planned, standardised, and developed. Over the past few decades, microbes with enhanced abilities for superior product generation have been identified (Babar et al., 2018; Kim et al., 2015). Latest improvements in metabolic engineering have aided the manipulation of various genetic components, including coding and regulatory regions, to maximize commercial benefits (Babar et al., 2018). Genomic methodologies aim to investigate the variations among individuals at both the germline and somatic levels by sequencing specific genomes. The transition from DNA microarray technology to DNA sequencing has enabled the thorough sequencing of entire genomes, providing a detailed characterization of an organism’s genomic landscape (Dai and Shen, 2022) whereas, transcriptomics involves the analysis of mRNA, microRNAs, long non-coding RNAs, and circular RNAs. The methods used in transcriptomics are designed to identify and enumerate RNA molecules transcribed from a specific genome at a particular time. Proteomics on the other hand focuses on understanding the functional significance of all proteins expressed within a cell, tissue, or organism by examining the flow of information via protein signalling and metabolomics contributed a vital part in the development of bioprocesses by providing a comprehensive overview of metabolic activities (Horgan and Kenny, 2011; Petricoin et al., 2002). Synthetic biology contributes a vital part in the production of high-performance strains for microbial manufacturing. A variety of microorganisms including bacteria, fungi, and microalgae can be employed in microbial production. However, synthetic biology methods primarily emphasis on the balanced blueprint of biosynthetic metabolisms for target outcome, as well as the creation and standardisation of these pathways and the heterologous production of the biosynthetic components (Wan et al., 2023). These approaches include the optimisation of fermentation process, optimisation of medium composition, scale up of fermentation, optimization of cell growth for manufacture of desired product, and strategies to decrease feedback inhibition and product toxicity (Figure 3.1) (Wan et al., 2023; Zhang et al., 2022).

6.1 Introduction 
Lignocellulosic Biomass (LCB) generated from the global consumption of fruit and vegetables rapidly generates approximately 140 billion metric tons of agricultural waste. Environmental pollution associated with these wastes, like land pollution, and increased greenhouse gas emissions, can be reduced through the bioconversion of wastes (renewable biomass resources) into value-added products in biorefineries (Babu et al., 2022). These value-added products synthesized for utilization in industries such as biofuels, biomaterials, or biochemicals are effective, reuseable, and enhance sustainability. These bioproducts are recuperated into useful biomolecules and oils for the food industries and dyes for the textile industries. The sustainability of these products can be acquired efficiently through costeffective pretreatments and bioprocess optimization methods (Haldar et al., 2020). The initial stage of value product chain development is the process modelling and optimizing, which, due to its complex nature and large scale, faces challenges in raw material availability, cost competitiveness, upscaling, and lack of technological maturity (Gerassimidou et al., 2021). Optimization of production processes like fermentation and chemical synthesis for manufacturing value-added products has become a focal point in research enhancement of biorefineries. There has been a revolution in the technology used in process designing and manufacturing practices in biorefineries. Advanced Artificial Intelligence (AI)-based approaches like Genetic Algorithm (GA), Fuzzy Inference System (FIS), and Artificial Neural Network (ANN) are being utilized along with conventional tools to optimize variables interacting in production processes. These techniques increase overall efficiency and enhance prediction accuracy and output of value-added products (Banerjee et al., 2025). Optimization of the bio processes enables higher productivity in parallel with lower environmental burdens. AI-based approaches integrated with conventional approaches need a large amount of experimental historical data to be successfully carried out (Arias et al., 2023). Advancement of biorefineries due to the rapid demand of value-added products as well as a solution to the greenhouse emissions, the integrated application of AI for process analysis needs to be understood. This chapter is a contribution towards upscaling the current knowledge base related to different approaches for the enhancement of production for value-added products. The chapter discusses the conventional techniques for value-added production and various optimization models. There is further discussion of advancements in the traditional approach using AI-based approaches and their features and benefits in biorefinery. Apart from different AI-based models, AI integrated with life cycle analysis for sustainability is also briefed. Finally, the chapter addresses current limitations in the field and outlines potential future directions for research and development.

The relentless march of urbanization, coupled with the growing uncertainties of a changing climate, casts a long shadow over the water security of our cities. Unlike their rural counterparts, urban areas face a distinct and often amplified set of challenges when drought strikes. The intricate web of municipal water supply, the concentrated demands of industry and commerce, and the sheer density of population render urban centers particularly vulnerable to the cascading impacts of water scarcity. When the taps run dry or restrictions tighten, the repercussions extend far beyond parched lawns and wilted gardens, impacting public health, economic stability, and the very fabric of urban life This chapter serves as an entry point into the critical field of urban drought management. We will delve into the unique characteristics that distinguish urban droughts from their rural counterparts, highlighting the interconnectedness of water systems and the amplified socioeconomic consequences within city limits. We will explore the increasing frequency and intensity of these events, driven by both natural climate variability and

The diffusion and adoption process represents a fundamental mechanism through which innovations, practices, and ideas spread through communities and social systems, making it essential for understanding how community mobilization initiatives can expand their reach and impact while building sustainable social change that extends beyond initial implementation sites. This process encompasses the complex social, psychological, and institutional factors that influence how individuals and communities learn about new approaches, evaluate their potential benefits and risks, and ultimately decide whether to adopt and integrate these innovations into their existing practices and belief systems. Understanding diffusion and adoption processes provides community mobilization practitioners with crucial insights into how successful interventions can be scaled up and replicated across different contexts while identifying the factors that facilitate or hinder

Traditional media channels have served as the backbone of agricultural communication in India for decades, playing a crucial role in disseminating information about farming practices, government schemes, and technological innovations to rural communities. These conventional platforms, including radio, television, print media, and community-based communication methods, continue to remain relevant and effective for promoting natural farming practices, despite the emergence of digital technologies. Understanding the strengths, limitations, and optimal utilization strategies for traditional media is essential for developing comprehensive communication programs that can reach diverse farming populations across various geographical and socio economic contexts. Radio broadcasting represents one of the most successful and enduring traditional media platforms for agricultural extension in India. All India Radio (AIR) has been actively playing a unique role in bridging the digital divide and supporting agricultural extension programmes in India since the experiment in 1952-53 with ‘An Indian Experiment in Farm Radio Forums’ at Poona (now Pune). The effectiveness of radio stems from its accessibility, affordability, and ability to reach illiterate farmers who may face barriers with text-based information sources. Radio programs dedicated to agriculture have evolved significantly from simple one-way

The Government of India has established a comprehensive institutional framework to promote natural farming through various schemes and initiatives that provide financial support, technical assistance, and policy backing to farmers transitioning from conventional to sustainable agricultural practices. These government interventions represent a strategic shift toward recognizing natural farming as a viable solution to address environmental degradation, input cost escalation, and farmer distress while enhancing agricultural sustainability and food security. The National Mission on Natural Farming (NMNF) represents the flagship government initiative specifically designed to promote chemical-free and climate-smart agriculture across the country. The Union Cabinet approved the National Mission on Natural Farming (NMNF) on 25th November 2024 as a standalone Centrally Sponsored Scheme under the Ministry of Agriculture & Farmers’ Welfare, with a target to initiate one crore farmers into natural farming over the next two years. The mission builds upon the earlier Bhartiya Prakritik Krishi Paddhati (BPKP)

The integration of bioinoculants and nanoparticles presents a promising strategy for enhancing sustainable agricultural practices, yet significant challenges impede their widespread adoption. Limited awareness among farmers regarding the benefits and applications of these technologies is a critical barrier, emphasizing the need for targeted educational initiatives. Additionally, the high cost of nanoparticle and bioinoculant formulations restricts accessibility, particularly for small-scale farmers. Standardization and quality control protocols are crucial to ensure consistent efficacy, as variability in bioinoculant formulations can compromise their effectiveness. Regulatory frameworks remain complex, further hindering commercialization and large-scale implementation. Environmental concerns are also prevalent, given the potential toxicity of nanoparticles like zinc oxide and silver nanoparticles, which may disrupt soil microbial communities. Despite these challenges, future prospects for bioinoculants and nanoparticles are promising. Integrating these technologies into sustainable farming practices can reduce the reliance on synthetic fertilizers and pesticides, as seen in the use of Azospirillum brasilense encapsulated in chitosan nanoparticles to enhance drought tolerance in maize. Furthermore, the application of Pseudomonas putida encapsulated in alginate nanoparticles has effectively mitigated heavy metal stress in tomato plants. Precision agriculture, employing data analytics and remote sensing, can optimize the targeted delivery of bioinoculants and nanoparticles, maximizing crop productivity and nutrient uptake. However, comprehensive in vivo studies are essential to assess long-term efficacy and environmental impact under field conditions. Future research should focus on developing ecofriendly nanomaterials, refining controlled-release systems, and conducting

Packaging machinery is a critical component in the food industry, enabling the efficient and consistent packaging of food products while maintaining safety, quality, and freshness. From automated filling and sealing systems to advanced inspection and labeling machines, packaging machinery plays a pivotal role in delivering food products to consumers in optimal condition. The machinery used in food packaging is designed to handle various product types, from solid and liquid foods to powders and granular items, each requiring specific handling, filling, and sealing techniques. In an industry where speed, hygiene, and precision are paramount, packaging machinery has evolved to include sophisticated features such as robotics, computer-controlled systems, and sensors that monitor critical parameters like weight, temperature, and fill levels. These innovations help manufacturers improve productivity, reduce waste, and ensure that food products meet regulatory standards and consumer expectations.

Global Packaging Regulations: FDA, EU, FSSAI, and Others FDA (U.S. Food and Drug Administration): The FDA ensures that food packaging materials are safe for contact with food in the United States. Under the Food, Drug, and Cosmetic Act (FDCA), the FDA provides guidelines through the Code of Federal Regulations (CFR), Title 21. Key points include: • Food Contact Substances (FCS): Materials in contact with food must be either pre-approved or recognized as safe (GRAS). Packaging materials, including plastics, paper, and adhesives, must undergo tests to ensure they do not release harmful substances into food. • Migration Limits: The FDA sets allowable limits on the migration of substances from packaging into food, including chemicals from inks, coatings, and polymers. • Food Packaging Certification: Packaging manufacturers must confirm that their materials meet FDA standards for safety in food contact

Introduction
Veterinary embryology is a fundamental branch of veterinary science that focuses on the study of the development of embryos in animals, tracing the journey from the moment of fertilization to the point where a fully developed fetus is formed. This field is not just an academic endeavor but a critical component of veterinary practice, research, and animal husbandry. It offers profound insights into the origins of life, the complex processes that drive the formation of tissues and organs, and the ways in which genetic and environmental factors interact to shape the development of an organism. The field of veterinary embryology is vast and encompasses several stages of development. The process begins with gametogenesis, where the reproductive cells—sperm in males and ova in females—are produced through a process of meiosis. These gametes are haploid, meaning they contain half the number of chromosomes found in somatic cells. The union of these gametes during fertilization restores the diploid number of chromosomes, marking the beginning of a new individual organism. The fertilized egg, or zygote, is the starting point of embryonic development. Following fertilization, the zygote undergoes a series of rapid cell divisions known as cleavage. During cleavage, the single-celled zygote divides without growing, resulting in a cluster of smaller cells called blastomeres. This process continues until the formation of a structure known as the blastocyst, which consists of an inner cell mass that will eventually develop into the embryo, and an outer layer of cells called the trophoblast, which will form the placenta. The blastocyst is a critical stage in development as it is involved in implantation into the uterine wall, a necessary step for establishing a successful pregnancy. The next major phase in embryonic development is gastrulation, a highly orchestrated process that results in the formation of three primary germ layers: the ectoderm, mesoderm, and endoderm. These layers are the foundation for all the tissues and organs in the body. The ectoderm gives rise to the nervous system, skin, and sensory organs; the mesoderm

Introduction
At the end of gastrulation, the mesoderm of the developing embryo differentiates into three regions: paraxial, intermediate, and lateral mesoderm. These regions play crucial roles in the formation of various body structures. As development proceeds, clefts form in the lateral mesoderm, which later coalesce to form a cavity. This cavity splits the lateral mesoderm into two layers: the somatic (outer) layer and the splanchnic (inner) layer. The space between these layers on each side of the midline becomes known as the coelomic cavity. These left and right coelomic cavities extend cranially, meet in front of the developing neural and cardiogenic plates, and fuse to form a horseshoe-shaped coelomic cavity. The walls of the developing coelomic cavity have two layers. The outer layer consists of somatic mesoderm, which fuses with ectoderm to form the somatopleure. The inner layer consists of splanchnic mesoderm, which fuses with endoderm to form the splanchnopleure. The mesodermal cells lining the coelomic cavity differentiate into a simple squamous epithelium called mesothelium. As cranial, caudal, and lateral folding occurs during embryonic development, the convex region of the horseshoe-shaped coelom eventually takes a ventral position to the foregut and developing heart, forming the primordium of the pericardial cavity. The developing coelomic cavities, initially continuous with one another at the umbilicus, become separated into intra-embryonic and extra-embryonic regions. The intra-embryonic coelom gives rise to the pericardial, pleural, and peritoneal cavities, while the extraembryonic coelom is associated with the developing fetal membranes. As the embryo folds laterally, the coelomic cavity divides into two separate components. The pleural cavities, which surround the developing lungs, are initially part of the pleuropericardial cavity, alongside the developing heart. As mesodermal folds, known as pleuropericardial folds, grow medially, they enclose the common cardinal veins and the phrenic nerves. These folds eventually separate the pleuro-pericardial cavity into two parts: the pleural cavities dorsally, and the pericardial cavities ventrally. The developing lungs grow

The increasing global emphasis on sustainable and environmentally friendly energy alternatives has placed biofuels at the forefront of green energy innovation. Derived from agricultural biomass and organic waste, biofuels represent a promising substitute for conventional fossil fuels, particularly in agrarian economies where such feedstocks are abundantly available. Agricultural biomass includes crop residues such as rice straw, wheat husk, corn stover, sugarcane bagasse, and oilseed cakes. Meanwhile, organic waste comprises food waste, animal manure, municipal solid waste, and industrial organic residues. Converting these materials into biofuels not only reduces landfill burden and environmental pollution but also cuts down greenhouse gas emissions and promotes the development of rural and circular economies. A variety of biofuels—including biogas, bioethanol, biodiesel, biohydrogen, and syngas—can be produced through two major conversion pathways:
• Biochemical conversion, which involves microbial and enzymatic processes such as fermentation and anaerobic digestion.
• Thermochemical conversion, which includes pyrolysis, gasification, and combustion processes to transform biomass into energy-dense fuels.
Types of Liquid Biofuels
The term biofuel commonly refers to liquid fuels produced from recently living plant material, unlike fossil fuels derived from ancient biomass. Among these, ethanol and biodiesel are the most prevalent forms:
• Ethanol: A type of alcohol produced through fermentation, usually from sugar- or starch-based crops like corn, sugarcane, or cassava. Ethanol is used either as a fuel substitute or blended with gasoline to reduce carbon emissions in vehicles.
• Biodiesel: Produced through the transesterification of oils extracted from plants and seeds (such as soybean, sunflower, or palm), biodiesel is a renewable fuel that can be used in standard diesel engines. It offers a biodegradable, less polluting alternative to petroleum-based diesel.

1. Introduction
Bioremediation is a process that utilizes biological agents, such asmicroorganisms, to eliminate pollutants, making it a natural and efficientmethod for environmental cleanup. This approach is considered cost-effectiveas it transforms harmful pollutants into less toxic substances through microbialdegradation or detoxification. Currently, many developing nations areprioritizing industrial growth, urbanization, and the use of agrochemicals inagriculture, which has heightened the importance of bioremediation and drawnsignificant attention to this practice. As a sustainable solution, bioremediationoffers a way to restore healthier ecosystems by removing pollutants from theenvironment (Fig. 1).

1. Introduction
The world’s ecosystem is facing significant challenges because of risingpopulations, more urbanization, and industrialization (Juwarkar et al.,2014). Significant environmental contamination has been caused by moderncivilizations, industrialization, population increase, intensive agriculturalpractices, human activities, and technological advancement (Lalevic et al.,2016).

Oil spills are defined as the unintentional release of liquid petroleum hydrocarbons into the environment, predominantly impacting marine ecosystems. This form of pollution, often caused by human activities, can also occur onterrestrial landscapes. Spills typically result from the discharge of crude oilfrom sources such as tankers, offshore platforms, drilling rigs, and wells, aswell as from refined petroleum products like gasoline and diesel (Smith etal., 2019). While such incidents are primarily accidental, they may arise fromvarious circumstances, including inadequate storage or poor maintenance,leading tocontainerleaks. Historically, one of the earliest documented oil spillsoccurred in 1907 in Batum, a region then part of the Russian Empire (moderndayBatumi, Georgia). This incident, involving a collision between an oil-ladenship and another vessel in the Black Sea, marked the beginning of recorded oilspill events, though historical records from that time remain limited (Johnsonet al., 2021). The consequences of oil spills are profound, affecting both theenvironment and the economy. On the ocean’s surface, oil disrupts aquaticecosystems by blocking sunlight penetration and depleting dissolved oxygenlevels, which are vital for marine life. Crude oil compromises the insulating andwaterproofing properties of fur and feathers, leading to hypothermia and deathin oil-coated birds and marine mammals. Additionally, ingesting oil can causeseveretoxicity, while damage to habitats and reproductive systems often delaysthe long-term recovery of affected species. Coastal vegetation, particularly inecosystems such as saltwater marshes and mangroves, is also highly vulnerable

It is the need of the hour that disposal of radioactive wastes be taken seriouslyand given appropriate attention. We house around one million gallons of liquidradioactive waste awaiting remediation at U.S. Department of Energy’s HanfordReservation alone (Parshley & McDermott, 2021). Not only the numbers are
but the increasing demand of nuclear energy paves the way forgeneration of even more radioactive waste in future. The conventional methodshave certain limitations. Ion-exchange resins have reported to bedegradedunder high radiation and chemical precipitation has proven to be ineffectivein treating low concentration of radionuclides found in groundwater, posingrisk for centuries (Zhang & Liu, 2020). Remediation methods including soil

Business efficiency refers to the ability of an organization to use its resources— such as time, money, labor, technology, and materials—in the most effective way to achieve maximum output with minimum waste. In simple terms, business efficiency means doing work in the best possible way with the least amount of effort, cost, and time while maintaining high quality. Efficiency is not only about working faster; it is about working smarter. A business is considered efficient when it produces more results with fewer resources. For example, if a company can produce 100 products in 5 hours instead of 8 hours by using better machines or automation, then the company has improved its efficiency.

SQL, or Structured Query Language, is a fundamental component in the domains of Machine Learning and Artificial Intelligence, serving as a powerful tool for managing, retrieving, and manipulating data stored in relational databases. In an era where data drives intelligent systems, SQL plays a crucial role in preparing and organizing datasets that form the backbone of machine learning models and AI applications. Its ability to efficiently handle large volumes of structured data makes it indispensable for data scientists, analysts, and engineers working in these fields. Originally developed in the 1970s at IBM by researchers Donald D. Chamberlin and Raymond F. Boyce, SQL was designed to provide a standardized way to interact with relational databases. Over time,

Data cleaning is one of the most important parts of machine learning. It plays an important role in building a machine learning model. Data quality is a significant aspect to train the ML model. Inaccurate data can have an impact on results. Data quality problems can occur anywhere in information systems. A technique that helps to convert improper data into meaningful data. Machine Learning is datadriven. With the data cleaning techniques, your Machine Learning model will perform better. So, it is important to process data before use. Without quality data, it is unwise to expect a correct output. Data cleaning refers to identifying and correcting errors in the dataset that may negatively impact a predictive model. It is used to refer to all kinds of tasks and activities to detect and repair errors in the data. These problems can be solved by using various data cleaning techniques. The process of fixing or removing incorrect, corrupted, incorrectly formatted, duplicate, or incomplete data within a dataset. When combining multiple data

Financial data visualization is the process of turning financial information into visual formats like charts, graphs, and dashboards. It helps finance teams interpret large datasets quickly, spot patterns or anomalies, and make betterinformed business decisions. Data visualization in finance is a craft of transforming complex financial numbers into accessible visual forms. Visual formats such as charts, graphs, dashboards, maps, and interactive displays serve as lenses through which data becomes visible and understandable. Finance practitioners navigate risk profiles, asset performance, expense trends, cash flows, and portfolio behavior more effectively when raw inputs become visual stories. Creation of visual representations hinges on careful selection of chart types, scaling, color, and annotation. Communicating precise meanings through visuals demands an understanding of data relationships, temporal changes, distributions, and comparisons.

Neurological examination in farm animals requires systematic assessment of behaviour, mental status, posture, gait, cranial nerve function, spinal reflexes and sensory responses. This chapter presents practical methods for localizing neurological lesions and characterizing abnormalities. Examination includes assessment of head position, coordination, proprioception, skin sensation, panniculus response, deep pain and various spinal reflexes. Cranial nerve tests such as menace response, pupillary light reflex and corneal reflex are also described. Abnormalities including head tilt, circling, ataxia, paresis and paralysis can provide valuable clues to lesion localization. The chapter emphasizes a structured neurological examination for accurate clinical assessment.
