Plant breeding is the purposeful manipulation of characters in plants to create new genotype with a set of desired characters. Hence, it may basically be referred to as designed manipulation of the heritable variation for the character concerned. Living organisms possess the remarkable capacity to convert the non-living materials into living staff, which results in movement, growth, metabolism and reproduction, and thus continuity of living organisms from one generation to the next is accomplished. The continuity of life through transmission of characters is the subject of the study of heredity, while the resemblances and differences between individuals of the same or different generations is the concern of the study of variation. These two universal processes of continuity and of change, which are referred to as “Heredity” and “Variation” are primary consequences of all organisms. Organized study of these two biological processes is the science of Genetics.
Plant breeding, which may be termed as evolution of plant type directed by the will of mankind, is basically the process of selection of character(s) from heritable variation. Desirable heritable variations can also be induced through some genetic consequences like, hybridization, segregation, mutation, changing the number of chromosomes, etc. So frame of plant breeding lay on three basics:

Origin, domestication and adaptation in India
Tomato was classified under Lycopersicon for several years although, initially Linnaeus (1753) classified it in the genus Solanum. Recently, molecular studies provided new data on the relationships of tomato-potato and based on these results, tomato has been again assigned to the genus Solanum. Solanum section Lycopersicon includes the cultivated tomato (Solanum lycopersicum) and its wild relatives, Solanum lycopersicum being the only domesticated species. The wild cherry tomato, Solanum lycopersicum var cerasiforme, the ancestor of the modern cultivated tomato has been originated in Peru-Ecuador-Bolivia region of the Andes. The Veracruz-Puebla region of Mexico is the centre of domestication of the cultivated tomato. From Mexico, tomato was taken to Italy, Spain, Portugal and other European countries, Africa and Middle East by the explorers in the 16th century. It was taken to Philippines after its discovery by Magellan in 1521, and from there it was taken to other Asian countries. Tomatoes did not have an easy passage even in Europe. The fruit got tagged as the “poison apple” in Britain, France, Spain and other European countries. Tomato moved to the USA from northern Europe around 1781 where it was first grown by Thomas Jefferson in Virginia.

Introduction
Clinical physiology is the branch of medical science that focuses on understanding the functional processes within the body under both normal and disease conditions. It emphasizes how body systems respond to disease, injury, and therapeutic interventions, and, forms the foundation of many diagnostic and therapeutic practices in veterinary medicine.
Importance and scope of Clinical Physiology in Veterinary Medicine: Clinical physiology is indispensable and plays a pivotal role in veterinary medicine. The knowledge allows for early detection of diseases, select effective treatment plans, and improved outcomes for animal patients. It is used to monitor the effects of treatment interventions, adjusting medications or therapies based on the physiological responses observed in the patient. A solid understanding of cardiovascular physiology is essential to manage heart failure condition in dog, and, treating respiratory diseases in cats or gastrointestinal
disorders in horses, relies on the knowledge of respiratory and digestive physiology. Beyond treatment, clinical physiology also plays a significant role in preventive medicine. Knowing the normal range of heart rates, blood pressure, and respiratory rates in different species allows veterinarians to quickly assess whether an animal is in distress or experiencing a pathological condition, and allow for timely intervention. It is also critical in managing the health of populations of animals, such as in livestock farming, where maintaining optimal physiological function is essential for productivity and welfare. The major systems in the body - including the cardiovascular, respiratory, digestive, nervous, endocrine, renal, musculoskeletal, reproductive, and immune systems, can be affected by a variety of diseases, and clinical physiology provides the framework for understanding these effects. It encompasses the study of physiological processes across a wide range of species, including companion animals, livestock, wildlife, and exotic animals.

3.1 Introduction
Understanding the Earth’s atmosphere—its intricate dynamics, ever-changing weather patterns, and long-term climate trends—hinges critically on the quality and detail of the observations we collect. While remote sensing technologies offer broad perspectives from a distance, a fundamental and indispensable category of atmospheric data comes from in situ observations. The term “in situ,” meaning “in place” or “on-site,” precisely describes the nature of these measurements: they are direct, physical readings taken within the atmospheric volume itself.
These direct observations are the bedrock of meteorological science. They provide the ground truth for atmospheric conditions, offering unparalleled precision in measuring parameters such as temperature, humidity, atmospheric pressure, wind speed and direction, and the characteristics of precipitation. Unlike indirect sensing, in situ methods involve instruments physically interacting with the air, yielding highly accurate and localized data points. This granular detail is crucial for a multitude of applications: it allows for the precise calibration of remote sensing instruments, provides essential validation for complex numerical weather prediction models, and enables scientists to dissect and understand fine-scale atmospheric processes that influence local weather.

Fruits and vegetables are more perishable and generally have a higher value compared to cereals, making them very important in terms of minimizing waste and improving employability in the food industry. The losses in fruits and vegetables are significant, but through effective post-harvest processing, these losses can be reduced, and surplus produce can be better utilized. This processing involves a variety of techniques that prepare fruits and vegetables for conversion into processed foods. The food preservation and processing industry has evolved from being a luxury to an essential sector, playing a crucial role in conserving and enhancing the utilization of fruits and vegetables.
To prevent waste during peak seasons and ensure availability during off-seasons, modern methods of storage and processing are necessary. These techniques allow for both large-scale and small-scale processing, extending the shelf life of produce for better distribution. The ultimate goal of food processing is to apply systematic techniques to preserve, process, package, store, and distribute food in a way that ensures a steady supply of diverse and nutritious food options, thereby improving food intake and nutritional standards, particularly during periods of low availability.
For effective preservation and processing, key prerequisites include cleaning, grading, and sorting the produce based on its maturity level. This ensures that only the highest quality fruits and vegetables are used in the processing chain, maintaining food safety, nutritional value, and consumer acceptability throughout the year.

Weather, while often benign and essential for life, can also manifest in powerful and destructive forms, posing significant threats to human life, property, and the environment. This chapter, “Weather Hazards,” will delve into the detailed nature of these potentially dangerous atmospheric phenomena.
We will explore a range of significant weather hazards, including severe storms such as thunderstorms, tornadoes, and hailstorms, which can bring intense winds, torrential rainfall, and damaging projectiles. We will also examine the characteristics and impacts of tropical cyclones (hurricanes, typhoons), known for their devastating winds, storm surges, and widespread flooding. Furthermore, we will discuss the dangers associated with extreme temperature events, including heat waves, characterized by prolonged periods of excessively hot weather, and cold waves, marked by extended periods of dangerously cold temperatures. We will also cover the challenges posed by heavy snowfall, blizzards, and ice storms.
For each hazard, we will investigate the meteorological conditions that lead to its development, the typical characteristics and intensity scales  used to classifyit, and the primary impacts it can have on society and the natural world. Understanding the formation, behavior, and potential consequences of these weather hazards is crucial for effective forecasting, issuing timely warnings, and implementing mitigation strategies to enhance safety and resilience.
Join us as we embark on a detailed exploration of the forces of nature that can transform familiar weather into formidable hazards.

Hydrates carbons (saccharides) found in nature (animals and plants) are classified into three groups based on the number of monosaccharides found or released upon acid hydrolysis. Monosaccharides the groups of carbohydrates.
3.1 Formulation of Monosaccharides
The molecular formula of any monosaccharide (mono=one and saccharide=sugar) is Cn(H2O)n or (CH2O)n. Rhamnose and Deoxyribose are exceptions to the general formula of carbohydrates. Acetic acid (C2H4O2) and formaldehyde (CH2O) are not carbohydrates but have the formula Cn(H2O)n or (CH2O)n. Fitting and Baeyer proposed the formula CHO-(CHOH)4-CH2OH, which indicates the presence of aldehyde and five hydroxyl groups.
More than one monosaccharide molecule unites to form disaccharides, oligosaccharides, and polysaccharides. Monosaccharides, being simpler units, cannot be broken down further. Generally, they have two to ten carbon atoms per molecule (dioses to decoses). The monosaccharides may have either aldehyde or ketone groups. The one possible aldodiose (CH2OH.CHO) is glycolaldehyde (2-hydroxyethanal), but ketodiose is not possible since there are only two carbons. The glucose molecular formula C6H12O6 represents the number of C, H, and O atoms but not groups. However, the proposed formula, CHO-(CHOH)4-CH2OH, indicates the presence of an aldehyde and five hydroxyl groups. These simple sugars or monosaccharides have carbon backbones linked by single bonds with hydrogen and hydroxyl groups attached in an unbranched manner.

6.1 Metabolism
Dietary components like carbohydrates, lipids, and proteins are continuously broken down and synthesized through various chemical reactions (exergonic or endergonic) that are concerned with energy. These processes not only break them down but also interconvert them for their synthesis. Dietary components, when utilized, are known as nutrients the body. The number of reactions occurring in living cells maintains the body cells and fluid’s homeostasis and dynamic status. To keep the dynamic state of a cell, many reactions are going on to synthesize or break down the different types and sizes of molecules. The total of these reactions is known as metabolism.
The metabolism may be anabolic or catabolic. Further, it may be aerobic or anaerobic, depending on oxygen availability. These four terms are explained below:
I. Aerobic and Anaerobic Metabolism
• Aerobic metabolism-- In aerobic metabolism, the carbohydrates (substrate) in the presence of oxygen are metabolized to release energy, carbon dioxide, and water. The released energy is converted to ATP by two processes in the mitochondria (the Krebs cycle and oxidative phosphorylation). In oxidation, the electrons released from a glucose molecule are transferred to reduced NAD+ and FAD. The oxygen (electron acceptor) is reduced to water. Water formation [from H2(g) and O2(g)] is an exothermic reaction. The energy released from the chemical bond of glucose is captured as ATP, and heat is released.

I. INTRODUCTION
The fruits and vegetables we eat and flowers and ornamentals we enjoy are biological entities. They breath, produce heat, perspire, are easily damaged, get diseases and finally die. These carry on processes characteristics of all living things before or after harvest to perform the metabolic activities:
1. to maintain cellular organization
2. to transport metabolites around the tissue and
3. to maintain membrane permeability.
The job of postharvest technologist is to understand life in fruits, vegetables and flowers and prolong their life as much as possible. The post harvest life of produce depends on the rate at which they use up their stored food reserves and their rate of water loss. The sugar and starches (carbohydrate derivatives) are stored in various parts of plants through a process known as photosynthesis occurring in growing plants and are used later to provide energy for further growth, development and to prolong post-harvest life. The process of photosynthesis in growing plants and respiration in harvested produce can be seen in Fig. 2.1. The released energy through process known as respiration occurs in plants before and after harvest. Thus, principal normal physiological processes leading to aging are respiration and transpiration.

The present study sought to empirically examine the perceived effects of contract farming on employment generation and poverty reduction. This was achieved by operationalising the construct through its technical, economic and social dimensions. Furthermore, the study explored relational linkages between the perceived effects of contract farming and the socio-economic attributes of farmers in the Cooch Behar district of West Bengal.
Distribution of respondents according to Age (X01), n=100
Interpretation: The obtained results reveal that the overall age ranges from 23 to 54 years, with a mean of 40.63 years and a standard deviation of 08.05. The coefficient of variation (C.V.) was 19.81%, indicating a relatively high level of uniformity in the age profile. A majority of respondents (62.00%) were middle-aged (34-49 years), followed by young farmers (23.00%) and a smaller proportion of older farmers (15.00%).
This suggests that the study area is predominantly characterised by young and middle-aged farmers. the relevance of age in contract farming is noteworthy, as active participation requires physical involvement, frequent training on modern farming practices and regular interactions with company representatives and vendors for input supply and technical guidance. Consequently, older farmers, often accustomed to traditional practices, may display relatively lower interest in contractual arrangements.
Distribution of respondents according to education (X02), n=100
Interpretation: The educational status of respondents ranged from a score of 02 to 17, with a mean of 08.47 and a standard deviation of 03.18. The relatively high coefficient of variation (37.54%) indicates lower consistency in educational attainment. A vast majority (75.00%) fell within the medium educational category, while 21.00 % had low education and only 04.00% possessed higher education. This indicates that the farming population is largely dominated by low to moderately educated farmers. The negligible representation of highly educated individuals in contract farming may be attributed to their scepticism about

INTRODUCTION
The production of products from grains, pulses, and oilseeds entails a series of processes aimed at converting raw agricultural materials into products that are ready for use or consumption. These processes typically take place in dedicated facilities like grain mills, pulse processing units, and oilseed crushing plants, where various types of equipment are employed at different stages of production. Below is an introduction to the main processes and an overview of the equipment commonly used for these operations.
The preparation of grain, pulse, and oilseed-based products plays a vital role in transforming raw agricultural produce into consumable goods, contributing significantly to food security and nutrition. These products are integral to the daily diets of people around the world, and the processes involved in their production are designed to enhance quality, shelf life, and marketability. The procedures that go into preparing these products vary depending on the type of raw material, but all involve a series of specialized steps that are typically carried out in dedicated processing facilities.Grain mills, pulse processing units, and oilseed crushing plants are the primary settings where these transformations take place. Each of these facilities is equipped with specific machinery to perform tasks such as cleaning, milling, sorting, and packaging, with the aim of creating high-quality end products that are ready for distribution. The operation of these different pieces of equipment is crucial for ensuring consistency in quality, efficiency in production, and minimal wastage.
The processing of grains, pulses, and oilseeds involves several stages, such as cleaning to remove impurities, grinding or crushing to break down the raw materials, and packaging for storage or shipment. Each stage requires different equipment, such as mills for grains, crushers for oilseeds, and sorting machines for pulses. Understanding the operation of these machines is essential for anyone

Data pre-processing is a crucial step in data analysis and machine learning that involves preparing raw data for further processing and analysis. Proper preprocessing helps in improving the quality of the data, which in turn enhances the performance of machine learning models. Smoothening VIS-NIR spectra enhances signal quality by reducing noise, crucial for better spectral data interpretation. Key methods include Savitzky-Golay and moving average filters, wavelet transform (WT), and frational derivatives.
Savitzky-Golay Filter: The Savitzky-Golay filter is widely used for smoothing spectral data. It preserves the original shape and features of the signal better than simple averaging filters.Savitzky-Golay Filter fits low-degree polynomials to successive subsets of data points using linear least squares, effectively preserving the signal’s original shape and features, making it ideal for spectroscopy. Moving Average:Moving Average is a simple method that reduces random noise by averaging neighboring data points. While effective, it can sometimes blur sharp features.
Wavelet Transform: Wavelet transform is effective for denoising spectral data, especially when dealing with non-stationary signals.Wavelet Transform (WT) decomposes spectral data into multiple scales, providing both time and frequency information. It is particularly useful for identifying features like peaks and trends. WT includes Continuous Wavelet Transform (CWT), Discrete Wavelet Transform (DWT), and Maximal Overlap Discrete Wavelet Transform (MODWT). Fourier Transform Filtering: Fourier transform can be used to remove highfrequency noise components from the spectra.
Median Filter: Median filtering is useful for removing outliers and preserving edges in the spectral data.
Fractional derivative:Fractional derivative generalizes traditional derivatives to non-integer (fractional) orders, allowing for arbitrary order derivatives. This provides a flexible, nuanced approach to modeling and analyzing complex, nonlinear, or memory-dependent behaviors.

1. Introduction Plants naturally contain compounds called phytochemicals. Due to their numerous therapeutic applications, these phytochemicals are becoming more and more well-known these days. Phytochemicals are essential in the fight against a variety of illnesses, including cancer, arthritis, and asthma. These phytochemicals have no side effects like pharmaceutical compounds do. Because the phytochemicals treat illnesses without harming people, they can also be referred to as “man-friendly medicines.” The primary topics of this study are phytochemical collection, extraction, and qualitative and quantitative analysis. In order to protect themselves against herbivores, many plants secrete chemical substances. Examples of therapeutic plants that include the main groups of pharmacologically active phytochemicals are provided below. Weeds that contain phytochemicals, like chickweed, dandelion, and nettle, are frequently found surrounding human settlements. Many phytochemicals, including curcumin, epigallocatechin gallate, genistein, and resveratrol are pan-assay interference compounds and are not useful in drug discovery.

5.1. Introduction
The people of every nation would be healthier if they adopted healthier lifestyles. A Good nutrition, daily exercise and proper sleep are the base of healthy living. A healthy lifestyle denoted by fit, energetic and at minimize possibility for disease. According to WHO, Healthy living is a way of living that helps you enjoy more aspects of your life. It is a way of living that lowers the risk of being seriously ill or dying early. Health is not just about avoiding a disease or illness.
5.2. Concept of Health
According to WHO, Health is the state of complete physical, mental and social well being and not merely absence of disease or infirmity. The holistic approach of health is the individual’s health and lifestyle considering all four factors, physical, intellectual, emotional and social. It concern about the whole body and mind not just a part of the body and the symptoms of the problem. It will look at the lifestyle of the individual such as nutritional deficiencies, reason of stress and why there is a lack of good health and wellbeing. A holistic approach will engage the individual taking responsibility for their health and well-being. They do this by educating themselves and being active in maintaining and improving their health and well-being.
5.2.1. Positive Health
Positive Health is the scientific study of health assets. A “health asset” is a factor that construct stronger health, over and above risk factors for disease. Positive Health works to find which specific health assets produce longer, healthy life, and which health assets lower disease risk and health care costs. The aim is to strive for optimal health —beyond the mere absence of illness.

Introduction 
In the rapidly evolving landscape of agricultural sciences, the integration of artificial intelligence (AI) and digital technologies is heralding a new era of innovation, efficiency, and sustainability. As the global population continues to grow and the impacts of climate change become increasingly pronounced, the demand for sustainable food production systems has never been more critical. AI and digital technologies are emerging as powerful tools to address these challenges, offering unprecedented opportunities to enhance food security, improve resource management, and build resilience against climate-related disruptions. AI-driven solutions, such as predictive analytics, machine learning, and precision agriculture, are transforming the way farmers cultivate crops, manage livestock, and optimize supply chains. These technologies enable real-time decision-making, allowing for more efficient use of resources such as water, fertilizers, and pesticides, while also reducing the environmental footprint of agricultural practices. The application of AI extends beyond the farm level, influencing every aspect of the agricultural value chain, from seed selection to post-harvest processing, distribution, and market access. The advent of the Internet of Things (IoT), coupled with advanced sensors and robotics, has further revolutionized agriculture by enabling the continuous monitoring of environmental conditions, soil health, and crop performance. IoT devices collect vast amounts of data, which, when analyzed using AI algorithms, provide actionable insights that empower farmers to make informed decisions. This data-driven approach not only enhances productivity but also contributes to sustainable farming practices by minimizing waste and optimizing resource allocation. Moreover, digital platforms and mobile technologies are bridging the gap between farmers and critical information, making it easier to access weather forecasts, market trends, and expert advice. These technologies are particularly transformative in developing regions, where they can provide smallholder farmers with the tools and knowledge needed to improve their livelihoods and contribute to food security. Additionally, blockchain technology is emerging as a solution for enhancing transparency and traceability in the food supply chain, ensuring that consumers have access to safe and ethically produced food.

Rainfall in India, is a phenomenon that is not just a meteorological event but the very lifeline of the subcontinent, profoundly shaping its landscapes, agriculture, and, most importantly for our study, its diverse aquatic ecosystems and the fisheries they support. India experiences a unique and dominant rainfall regime driven primarily by the monsoon, a seasonal reversal of wind patterns. The arrival, intensity, duration, and spatial distribution of this rainfall have farreaching consequences for the availability of freshwater, the health of rivers, lakes, and wetlands, and the productivity of coastal and marine environments. For aspiring fisheries professionals in India, a thorough understanding of the patterns and vagaries of Indian rainfall is indispensable.
Consider the sheer diversity of aquatic habitats across India, from the snowfed rivers of the Himalayas to the monsoonal wetlands of the Gangetic plains, the brackish backwaters of Kerala, and the vast coastline. The characteristics and productivity of each of these systems are intricately linked to the patterns of rainfall they receive. The monsoon replenishes rivers and groundwater, sustains agricultural practices that can impact water quality, influences the nutrient flow into coastal waters, and can even trigger crucial life cycle events for many aquatic species (Fig. 7.1).

Introduction 
The evolution of digital governance in the 21st century has significantly redefined how public institutions function, deliver services, and interact with citizens. This transformation, enabled and accelerated by Information and Communication Technologies (ICTs), is not merely technical, but deeply institutional, cultural, and political. As states move toward more digitized, networked, and citizen-responsive systems, drawing upon theoretical frameworks that help explain, interpret, and evaluate these complex dynamics becomes essential. Theories provide the conceptual scaffolding necessary for analyzing the design, implementation, outcomes, and unintended consequences of digital governance practices. At its core, a theory systematically explains a phenomenon or set of phenomena. It involves a coherent set of interrelated concepts, assumptions, and propositions that define causal relationships and offer predictive insights (Kerlinger, 2000). According to Prasad et al. (2017), theory represents a systematic grouping of interdependent concepts that offer a framework to organize existing knowledge, explain observable events, and predict yet-unobserved outcomes. Hollander (1967) adds that theories contain one or more functional statements or propositions that articulate relationships between variables to account for empirical realities. Central to any theory are concepts, the building blocks that articulate the causal linkages and assumptions within a conceptual system. When structured together, these elements form a deductive framework for reasoning and explanation. In sum, theory allows us to understand what is happening in digital governance and why, how, and with what implications. Digital governance, distinct from narrower terms like e-government or e-governance, is a multi-layered process involving the reconfiguration of power, the redesign of institutions, the engagement of diverse stakeholders, and the transformation of public value creation in a digitally mediated environment. It encompasses dimensions of public administration, information systems,

Soil-Water-Plant Relationships and Irrigation Scheduling Concepts
A good understanding of soil-water-plant relationships is the foundation for understanding irrigation concepts.
Water reaches the soil through irrigation, precipitation, or from groundwater drawn up into the root zone through “capillary action”. To be available to plants, it must be held by the soil strongly enough so it is not lost to gravity before the plant gets it, but not so strongly that the plant cannot extract it from the soil. At the same time, the roots must have sufficient aeration to function properly.
Roots are responsible for obtaining almost all of the plant’s water and nutrients. These substances move through the soil during and after irrigation/fertigation and rainfall. In addition, root systems are continually growing and branching to seek out water and nutrients. Root hairs are very fine structures that extend at right angles to the roots. Water and nutrients predominantly enter the root system via specialized cells near the tips of root hairs.
The xylem is the cellular pathway through the plant that transports water from the roots to the leaves for use in photosynthesis and to cool the plant by evaporation. The process by which water vapour is released to the atmosphere by the leaves and other parts of a living plant, resulting in evaporative cooling, is called transpiration. The xylem also transports water and nutrients to other parts of the plant. In a living plant, the xylem is completely filled with water, just as the veins and arteries of the human circulatory system are filled with blood. The plant needs a continual replacement of water lost through transpiration to keep the xylem full of water, and of course, this has to be accomplished without an organ analogous to a human heart. Tomato plants

Saffron, the legendary crop of Kashmir, India, is an important food adjunct, that is, food flavorant and food colorant, and, is also reputed to possess several medicinal properties. The recorded accounts of saffron cultivation in Kashmir dates back to AD 550, nearly four centuries earlier than its recorded cultivation in Spain by the Arabs around AD 961. The saffron fields, from mid-October to early November, when saffron plants are in full bloom, on a moonlit night, present a wonderful sight and a good source of fascination to many tourists. But, surprisingly, it’s cultivation in Jammu and Kashmir in India does not seem to be based on scientific research and the growers have some superstitions, notions and methods of their own. Therefore, saffron-growing areas are those very localities where they have been since ancient times (550 AD), and is also their out-dated methods of curing, drying and packing, which can be improved considerably. Over 100 species of saffron genus Crocus are distributed worldwide, but, only Crocus sativus has received some attention and is cultivated in several countries. Saffron consists of dried tri-lobed stigmas of Crocus sativus, which is a bulbous perennial with globular corms. The plant is only 15-25cm tall, native of Southern Europe and cultivated in the Mediterranean countries, in particular, Spain, Austria, France, Greece, besides England, Turkey, India (in Jammu and Kashmir State, an Indian Union territory), and The People’s Republic of Iran. It is also grown in the Orient. True Saffron must not be confused with either meadow saffron (Colchicum autumnale Linn; Family: Liliaceae) or Safflower or Bastard Saffron (Carthamus tinctorium; Family: Compositae), which are

15.2 Hydro Forming
The word “hydroforming” describes the metal forming procedures where the material blank is deformed by hydraulic pressure. There are difficulties with sealing, pressurization schedule, anticontamination in the pressure system, and cleaning the workpiece and equipment after direct contact between the pressurized fluid and the blank material. In certain instances, the necessary hydroforming pressure may surpass 350 MPa, contingent upon the setup of the process and the thickness of the material. Hydroforming procedures are divided into two categories, viz. sheet metal hydroforming and tube hydroforming, depending on the geometry of the blank.
15.2.1 Sheet Metal Hydro forming
When it comes to tooling, sheet metal hydro forming is less complicated than typical sheet metal stamping. Only one side of the tooling, typically the lower side needs to be created for the sheet metal hydro forming process. The hydro forming

2.1 Introduction 
The world is encountering a severe power and environmental crisis. Adopting sustainable progress is the best means to protect our environment and maximise the use of available resources. The urgent issues, encompassing diverse types of pollution and carbon emissions, highlight the necessity to shift towards renewable energy sources. This shift is essential for diminishing our dependence on fossil fuels, addressing the on-going challenges regarding climate change, and confronting the exhaustion of current energy reserves. Furthermore, mitigating water pollution is an essential component of ensuring ecological sustainability [1,2]. Water supplies are rapidly being contaminated due to diverse contaminants including heavy metals, and harmful chemicals. While industrialization is critical for societal growth, it is critical to recognise the negative environmental consequences caused by numerous processes that emit hazardous substances. Improper disposal of untreated wastewater can negatively impact ecology and biodiversity [3]. As a result, it is critical to use environmentally friendly and sustainable treatment methods that adhere to green development principles. This will bolster industrialization efforts while upholding water pollution safeguards for recovery and reuse. Given the prevailing energy crisis, traditional wastewater treatment facilities have become financially unsustainable due to their high energy consumption. Traditional wastewater treatment is both costly and demands substantial energy resources. Furthermore, these approaches fall short of efficiently eradicating recalcitrant organic waste, heavy metals, and other persistent contaminants. Moreover, many of these treatment processes require regeneration. Microbial fuel cell (MFC) technology has emerged as an ecofriendly treatment option capable of effectively eliminating stubborn organic pollutants and heavy metals over the long term. Microbial fuel cells are chosen over other current treatment methods because to their reduced energy needs and lower chemical usage [4,5]. In addition to lowering energy usage, MFCs possess the ability to produce ample bioenergy, which can help alleviate the energy shortage. This provides a cleaner alternative for generating renewable energy in favour of sustainable development and environmental protection as depicted in Figure 2.1.

Introduction 
Augmented energy demand as well as impacts of employment of fossil coals on human health and environment, stresses and imposes the need to lessen the use of conventional fuels or replace them. Equally, global warming has stretched to a distressing level due to many diverse anthropogenic actions leading to increased pollution. The alternate energy sources are desirable that might be the conspicuous and sustainable approach of enabling environmental remediation, besides meeting the global energy call (Grosser et al 2016, Kanchanasutha et al 2016). A potential solution is generation of Biofuels, either conventional biofuels produced from agricultural crops or advanced biofuels produced from wastes, inedible crops or forestry products (Sreedevi Sarsan et al 2021). Advanced biofuels production especially by the utilization of agricultural and animal wastes using new technologies and processes are gaining increased interest among researchers and general public all over the world. Food waste, municipal trash, animal waste and other wastes can all be utilised as feedstocks to create biogas, a clean and sustainable energy source and thus may be the ideal replacement for traditional energy sources. The raw biomass may be converted into fuel products like biogas by briquetting, gasification, and anaerobic digestion, among other processes (Deepanraj et al 2015). In comparison to landfills, incinerations, and composting processes, anaerobic digestion (AD) is suggested as an inexpensive and environmentally benign technique for the generation of renewable energy (Van Forest et al 2012; Nishio et al 2007; Capson-Tojo et al 2016; Xu, F et al 2018; Cha, M et al 2020). The production of energy-rich biogas and alleviation of issues related to the removal of organic waste are all achieved by anaerobic digestion (AD) of organic solids (Sonakya et al 2001). This is since AD is a highly energy-efficient and ecologically benign technique. In an atmosphere devoid of oxygen, the AD system uses anaerobic microbes to transform the naturally occurring substances in the biomass into biogas. The primary byproduct of AD, biogas, has a methane content of roughly 50-70% by volume and 30- 40% atmospheric carbon dioxide (CO2) when feedstocks are digested under anaerobic circumstances, with small levels of hydrogen sulphide (H2S) (0.1-3% v/v), humidity, and other trace pollutants also present (Sahota et al. 2018). The generation of biogas is known to be influenced by factors such as waste types, pretreatment procedures, the microorganisms or enzymes added, operation circumstances and design of the digestors (Mao et al 2015).

Nano-bioinoculants are revolutionizing modern agriculture, empowering farmers with an innovative and environment-friendly approach to crop cultivation. This chapter delves into the fascinating world of these tiny technological breakthroughs that work seamlessly with nature to significantly enhance crop yields in a sustainable manner. Their remarkable ability to deliver essential nutrients directly to plants, fortify crops against drought and diseases, and minimize the reliance on harmful chemicals will be highlighted. By presenting real-world success stories, we will illustrate how farmers are harnessing these advancements to produce healthier food while conserving valuable resources. Nevertheless, the path to widespread adoption is not without its challenges; which will be confronted for critical issues such as costs, regulatory hurdles, and the transition of these solutions from laboratories to agricultural fields. Looking ahead, we will envision a future where nano-bioinoculants synergize with other cutting-edge farming technologies, paving the way for truly sustainable food systems that can meet the demands of our growing population.

Fruits and vegetables are more perishable and generally have a higher value compared to cereals, making them very important in terms of minimizing waste and improving employability in the food industry. The losses in fruits and vegetables are significant, but through effective post-harvest processing, these losses can be reduced, and surplus produce can be better utilized. This processing involves a variety of techniques that prepare fruits and vegetables for conversion into processed foods. The food preservation and processing industry has evolved from being a luxury to an essential sector, playing a crucial role in conserving and enhancing the utilization of fruits and vegetables. To prevent waste during peak seasons and ensure availability during off-seasons, modern methods of storage and processing are necessary. These techniques allow for both large-scale and small-scale processing, extending the shelf life of produce for better distribution. The ultimate goal of food processing is to apply systematic techniques to preserve, process, package, store, and distribute food in a way that ensures a steady supply of diverse and nutritious food options, thereby improving food intake and nutritional standards, particularly during periods of low availability.
For effective preservation and processing, key prerequisites include cleaning, grading, and sorting the produce based on its maturity level. This ensures that only the highest quality fruits and vegetables are used in the processing chain, maintaining food safety, nutritional value, and consumer acceptability throughout the year.
CLEANING OF AGRICULTURAL COMMODITIES
Blanching is a unit operation used in food processing to remove contaminating materials from food and prepare the surface for further processing. In vegetable processing, blanching serves the additional purpose of cleaning the product. This process involves briefly exposing the food to heat, typically by immersing it in hot water or steam, which helps to remove dirt, enzymes, and microbial contamination. By doing so, blanching not only improves the quality of the food but also prevents microbial growth during storage or delays in processing. This early removal of contaminants ensures that the remaining bulk of food is preserved and remains safe for consumption throughout its shelf life.

Dyes are compounds after addition to a substrate, for a moment give it a colorthrough a process that modifies the colored substance’s crystal structure (Bafanaet al., 2011). Such varieties of compounds with significant coloring capacityare widely employed in the textile, pharmaceutical, food, photographic, andpaper industries (Zollinger et al., 1987). Dyes can adhere to suitable surfacesthrough methods such as dissolving, forming covalent bonds, complexing withsalts or metals, physically adsorbing, or being mechanically retained (Kirkand Othmer, 2004). The chemical structure and application of dyes determine
their classification. The dye color is produced by a collection of atoms calledchromophores. Chromophore centres, which are responsible for color, consistof various functional groups like azo, anthraquinone,methine, nitro, arylmethane, carbonyl, and others. Additionally, substituents that either donateor withdraw electrons to enhance or create the color of these chromophoresare called auxochromes. Common examples of auxochromes include amine,carboxyl, sulfonate, and hydroxyl groups. There are three methods for dyingtextile materials: batch, continuous, and semi-continuous. Thekind of materialincluding yarn, fabric, fiber, clothing, and fabric structure as well as the generalfiber size of the dye lot, type, and quality standards of the dyed fabric, all playa role in determining the dyeing method used. Among these techniques, theprocess called the batch procedure is the most frequently employed for dyeingtextile materials. (Ogugbue et al., 2011).

Kudumbashree, is the flagship poverty eradication and women’s empowerment programme, of the Government of Kerala, and is one of India’s most successful community development missions. Launched in 1998 by the Government of Kerala in collaboration with NABARD and the Government of India, Kudumbashree operates through a unique three-tier community network that connects millions of women across the state. Its model- built on economic empowerment, social inclusion, and participatory governance- has become a benchmark for women-led development both nationally and internationally. At the foundation of Kudumbashree lies its grassroots structure: the Neighbourhood Group (NHG) of 10–20 women; the Area Development Society (ADS) at ward level; and the Community Development Society (CDS) at the panchayat level. This federated network enables women to mobilize

Entomopathogens are microorganisms that infect and kill insects, mites and other arthropods and are widely employed in biological control and integrated pest management. They include bacteria, fungi, viruses and entomopathogenic nematodes. Their effectiveness depends greatly on temperature, humidity, solar radiation, rainfall and interactions among the host, pathogen and environment. Climate change can alter pest populations as well as pathogen survival, infectivity, multiplication and field persistence. These effects may enhance some microbial-control agents while reducing the effectiveness of others. This chapter introduces major groups of entomopathogens and examines their performance under present and projected climatic conditions, emphasizing their importance in environmentally responsible pest management.

The increasing capabilities of Large Language Models have created strong demand for real-time AI services, but their computational complexity makes low-latency deployment difficult on conventional systems. Transformer models require substantial memory, high computational throughput and efficient data movement, creating challenges for mobile devices, embedded systems, edge platforms and latency-sensitive applications. This chapter introduces hardware–software co-design as an integrated strategy for addressing these challenges. Rather than optimizing hardware and software independently, co-design aligns model algorithms with the characteristics of processors, memory hierarchies, accelerators and communication systems. The chapter examines hardware platforms including GPUs, TPUs, FPGAs and ASICs, together with software techniques such as quantization, pruning, knowledge distillation, operator fusion and memory scheduling. Hybrid architectures are discussed for reducing latency, improving throughput, lowering energy consumption and increasing scalability. Applications in healthcare, finance, autonomous driving, robotics, industrial IoT and real-time translation illustrate the importance of efficient inference. The chapter demonstrates that coordinated optimization across the full computing stack can bridge the gap between LLM capability and practical real-time deployment while maintaining acceptable accuracy and reliability.

Digital technologies are transforming horticultural production by enabling data-driven crop management and precise decision-making. This chapter introduces agricultural informatics, sensors, Internet of Things, remote sensing, drones, artificial intelligence, machine learning, geographic information systems, robotics, and precision technologies. These tools can support crop monitoring, disease detection, irrigation scheduling, nutrient management, yield prediction, phenotyping, and resource optimization. AI-based image analysis can identify symptoms and assist in early crop diagnosis, while sensors provide continuous information about soil and plant conditions. The chapter emphasizes the integration of digital data with practical horticultural knowledge to improve productivity, profitability, sustainability, and resilience while reducing unnecessary inputs and improving decision-making.

Horticultural commodities are highly perishable because they remain physiologically active after harvest and are susceptible to moisture loss, respiration, microbial deterioration, mechanical injury, and physiological disorders. This chapter introduces principles of harvesting maturity, handling, grading, sorting, packaging, storage, transportation, and cold-chain management. Appropriate post-harvest practices help preserve freshness, nutritional quality, appearance, and market value while reducing losses. The chapter also examines value addition through processing, drying, preservation, packaging, and development of new horticultural products. Efficient post-harvest systems connect production with consumers and markets and are particularly important for high-value fruits, vegetables, flowers, spices, and other perishable commodities. Together, improved technology, quality management, and value addition can significantly increase farmer income and strengthen horticultural value chains.

INTRODUCTION

Resource, land use patterns and erosion of homrgardens biodiversity have been at the core of the debate on sustainable ecosystem management today. Homegardens are considered as a resource system of multiple functions and an important wheels of vehicle for biodiversity, environmental and ecological benefits, food security (either directly food grains, fruits, vegetables and root crops or indirectly improving soil conditions and there by promoting understory crop productivity especially on degraded sites), soil conservation potential, nutritional security, socio-cultural as well as mitigation of the impact of climate change and job creation in developing and under developed countries. While increasing human population, urbanization and pressure on the earth’s ecosystems, has resulted in the breakdown of these traditional agroforestry systems, accompanied by increasing economic, cultural, nutritional, and environmental problems, there is little awareness that homegardens are under similar threats.

C horizon: i) A horizon or layer, excluding hard bedrock, that is little affected by pedogenic processes and lacks properties of O, A, E, or B horizons —note the material of C horizons may be either like or unlike that from which the solum presumably formed. ii) A mineral horizon generally beneath the soil solum that is relatively unaffected by biological activity and pedogenesis and is lacking properties diagnostic of an a horizon or a b horizon. See also Soil horizon.

Abstract

Intensification of agriculture during the last few decades has resulted in considerable depletion of the productivity of Indian soils and the balance sheet of potassium (K) is highly negative due to very low level of K fertilization. Although the need for balanced fertilization is known for many years, it is not always observed in practice by farmers. Since the effects of nitrogen are easily seen and crops look more vigorous and yield better, excessive use of nitrogenous fertilizers, accompanied by an inadequate supply of other nutrients, is considered by farmers as a reasonable insurance against yield losses. Often, the lack of K restricts nitrogen uptake and utilization, and hence plant growth. When K is limiting, nitrogen fertilizers are used inefficiently by the plants. This nutrient imbalance is thus closely associated with low nitrogen-use-efficiency (NUE) of crop plants, which is detrimental to crop production and environment – because of the consequences of N unused by the crop.

Introduction

Drought is the most common adverse environmental factor which limits crop production in different parts of the world. Often drought is accompanied by relatively high temperatures, which promote evapotranspiration, and hence could accentuate the effects of drought and thereby further reduce crop yields. Since these events occur more frequently in tropical and semitropical regions where most of the developing countries are situated, droughts are often associated with food shortages and an overall setback to developmental activities. Therefore, raising of drought-resistant crops is common sense to achieve stability in production and to enhance the possibility of self-suficiency in food. Consequently, breeding for drought resistance is a major objective of many research programmes in the international and national institutions. This has been so for the past several decades. But, it is disappointing that, there has not been any measurable success in these programmes compared with the success achieved in breeding for yield; or breeding for disease resistance or breeding for quality attributes. In fact, this was amply expressed by Arnon (1980) when he stated “Breeding for drought resistance has been a consistent theme for as long as I remember and probably the greatest source of wasted breeding efforts in the whole field of plant breeding.” However, the fact remains that we do hear of drought resistant varieties in many crops. For example, C-306 in wheat, Lalnakanda in rice and M 35-1 in Sorghum are some of the better known examples in India. It is also claimed that a large number of cultures among the Assam Rice Collection exhibit a considerably high degree of drought tolerance. Many land races and wild relatives of several crop species are said to contain drought resistant traits, which could be profitably utilised in breeding programmes. This situation is not unique to India alone but is a common experience in different parts of the world. However, to afirm a conviction a short questionnaire to assess the current state-of-art on breeding for drought resistance was distributed to 75 distinguished plant breeders and plant physiologists all over the world. The questionnaire and a summary based on the responses is as follows:

Vegetables are cheaper source of carbohydrates, proteins, minerals, vitamins and dietary fibers, and hence, assume a place of very great importance in the diet of individuals. All kinds of vegetable are grown almost universally. India occupies the prime position in the production of vegetable crops and is the second largest producer of vegetables in the world. The area and production of vegetables in India have been increasing during the post-green revolution period, and the country is heading towards another revolution in the form of Golden Revolution. However, there is an utmost requirement for genetic improvement of vegetable crops in terms of productivity, qualitative characters and resistance to biotic and abiotic stresses. For any genetic improvement programme, the presence of genetic variation is pre-requisite and mutation is the ultimate source of this heritable variation.

Mutation technique that holds promise of generating a much wider desirable variability than classical breeding has been refined. Out of 2275 mutant varieties worldwide in all crops, as many as 66 mutants are in vegetables. In terms of percentage, China, India, USSR, The Netherlands, The United States of America and Japan account for 26.8, 11.5, 9.3, 7.8, 5.7 and 5.3%, respectively of mutagen varieties in all crops. Such varieties are 3% in case of vegetables. After mutation treatment by a mutagen to a specific plant, DNA alterations (deletion, duplication, inversion, translocation, or transposition of larger DNA fragments, or simple basic pair changes) occur and lead to the DNA sequence change. Hence, new characteristics of that plant are established. In fact, induced mutations supply us with many new plant lines, which may be used as primary materials for crop breeding. Hence, mutation breeding seems to be an effective and ultimate option to improve vegetable crops in the shortest possible time. A large number of new promising varieties in different crops, including vegetables, have successfully been developed worldwide using various mutagens (Chopra, 2005).

Mulching is a practice of covering the surface of soil with plastics, organic and non-organic materials like straw, grasses, sands, stones (boulders), synthetic plastics, etc. to reduce evaporation and to moderate wide fluctuations in diurnal soil temperature, especially in the root zone environment. It controls external evaporability and reduces energy supply to the evaporating site by cutting off solar radiation falling on the ground. Its main function is limited to control first stage of drying, which helps in improving moisture status and reducing soil temperature (Loy and Wells, 1975), besides checking seedling mortality and improving crop stand. It also suppresses weed-flora and reduces weed competition with crop for water and nutrients making them available in greater quantities for crop plants. Moreover, mulching helps in increasing downward movement of water, and its storage deep in the profiles escapes evaporation due to reduction in thermal gradients and exchange of vapours. The effectiveness of mulches in conserving moisture has generally been found to be higher under more frequency of rainfall, drought conditions and also during early period of plant growth when canopy cover remains scanty.

The beginning of the 20^th century was heralded by methodological revolution in geomorphological studies brought in by Davis (1899). His classical model of geographical cycle defined by him ‘ as a period of time during which and uplifted landmass undergoes its transformation by the process of land sculpture ending into a low featureless plain (peneplain)’ dominated the geomorphological investigations all over the world throughout 1^st half of the 20^th century.

The statistical techniques by Horton (1932 and 1945) brought quantitative revolution in the field of geomorphology when he presented quantitative analysis of morphometric characteristics of fluvially originated drainage basin. Post 1950 geomorphology has undergone vast change in the methods and approaches to the study of landforms, conceptual framework, paradigm and thrust areas of study. The most outstanding contribution to the advancement of geomorphological knowledge in this period is the adoption of quantitative approach based on deductive scientific method to the study of landforms and processes at short spatial and temporal scales (Strahler, 1956 and Schumm, 1956).

Several attempts have been made in the world in past to classify large territories and landforms into morpho-units. Valuable contributions pertaining to landform analysis have been summarized below: Joerg (1914) subdivided North America into natural regions, Fenneman (1914) established physiographic boundaries and gave physiographic divisions of the United States, whereas Anderson (1941) gave physiographic divisions of Columbia plateau. Howard and Spock (1940) and Weaver (1965) presented the excellent ways of classification of the landforms while Wood and Snell (1960) applied the quantitative systems for the classification of the landforms. However, Linton (1951) and Hammond (1954 and 1965) gave techniques for mapping delineating small scale and large-scale landforms.

ABSTRACT

Soil borne fungal pathogen causing root diseases of vegetables are difficult to control by chemical methods. The existing biocontrol bacteria are not very effective in control of soil borne fungal pathogens. As such very less number of bacterial biopesticide is available commercially to control the fungal pathogens. Increasing concerns in recent years about human health and environmental problems due to chemical pesticides, couple with increasing pest resistant to chemical, have led to a reappraisal of our approach to control pest and disease in crops. The trends now are towards a management concept in which the best combination of tools is used to manage plant diseases below economic thresholds with minimal risk to human health and environment. The modern management concept includes extensive use of biocontrol agents which are harmless to non-target organisms. Development of effective technology for control of pest and disease by using microbial resources of a region to enhance the quality of ecosystem is a potential alternative approach to chemical control of plant diseases. In such strategy, search for microorganisms and biological system is an important prerequisite prior to development and practical exploitation of biocontrol. Rhizosphere microorganisms are shown to be perspective candidate for biocontrol agent as they provide the front line of defense for plant roots against the attack by various plant pathogens causing the most diseases of vegetables and crops. Chemical control of soil-borne fungal pathogen had been the subject of growing concern because of their adverse effect on the environment and emergence of chemical pesticide resistant to plant pathogen, moreover, soil borne pathogens are very difficult to control. Crop rotation, breeding for resistant plant varieties and application of pesticides are insufficient to control root diseases of important plants because they survive as sclerotia and has got wide host range.

Fruits are very important in human diet, as they are chief sources of vitamins and micronutrients. Variable agro-climatic condition in India provides tremendous scope for cultivation of fruit crops. Among fruits, apple, pear, cherry, plum, peach, apricot, walnut and almond (temperate fruits); mango, grapes, banana, citrus, pineapple (tropical and subtropical fruits); pomegranate (arid zone fruit) are important fruit grown in India. Insect-pests are amongst one of the major constraint for the low productivity of fruit crops in India. Therefore, it is important to have some information of the important insect-pests of fruit tree and their management. Over 1000 species of insects found damaging fruit trees all over the world, of these as many as 800 insect species have been intercepted from India (Butani, 1979). The information on insect pests of apple and other temperate fruits in India have been reviewed by several workers (Pruthi and Batra, 1960; Butani, 1979; Bhalla and Gupta, 1993; Sharma and Thakur, 1996). In India, more than 200 insect species on apple trees (Bhalla and Pawar, 1977), 70 species on pear, 80 species on peach, 60 species on plum, 30 species on apricot (Butani, 1979), 85 species on grapevine (Tandon and Verghese, 1994), 175 species on mango, 182 species on banana (Dhaliwal et al., 2006) and 250 species of insect and mites on citrus (Pruthi and Mani, 1945; Wadhi and Batra, 1964; Rajput and Hari Babu, 1985; Tandon, 1993) have been reported. The important insect-pests of fruits are as follows:

In this chapter of machine learning algorithms we will cover the basic algorithms of machine learning with their implementation using dataset and discuss their pro’s and cons of algorithms for better understanding and how to use them in any project or with any dataset to get an correct result which can useful for research or study.

Key Component

We defined a data set composed of audio, images and binary labels that provided an understanding of how we could train a model from snippets to classifications. This sort of problem is one of many kinds of machine learning problems when we try and predict a specified unknown label given known inputs, provided that a dataset of examples for which labels are known is called supervised learning. Let’s discus what are the major key components we have to get there

Mole (mol)

1 mole of any substance contains 6.02 x 10²³ units. The number of moles in a given weight of substance can be calculated using following equation.

4.1 Introduction

India is a land of many rivers, lakes, ponds, coastal, marines and mountains. Its geographical area of about 329 million hectare is crises crossed by a large number of small and medium, large rivers, some of them figuring amongst the mighty rivers of the world. The rivers and mountains have a greater significance in the history of Indian civilizations, development, religious and spiritual life. It may not be an exaggeration to say that the rivers are the heart and soul of the Indian civilizations

India is a union of States with a federal set up. Politically, the country is divided into 26 States and 7 Union Territories. A major part of India’s population of 869 millions (1991 census) is rural and agriculturally oriented for whom the rivers are the source of their life. India is a land of many religions, diversity of cultures and languages. The different regions of the country have different cultural, linguistic and other ethnic groups. The land and people present a vast panorama of diversity in unity. Physiographically, India may be divided into seven well-defined regions.

Litchi (Litchi chinensis Sonn.) is a subtropical and evergreen tree belonging to the family Sapindaceae. This fruit has highly specific climatic adaptability due to chilling requirement for floral initiation on one hand and the damage caused due to high summer temperature along with low relative humidity during fruit growth period on the other hand. Some other factors influencing expansion in different regions of the world are difficulties in establishment of plants in nursery and orchards, bearing and further into harvesting and post-harvest management. Calcium rich soil with mycorrhizae is best suited for the luxuriant growth of litchi plants which are commercially propagated by air-layering or gootee.

There has been a substantial increase in the area and production of litchi in India during the past 50 years. The area has increased from 9400 ha (1949–1950) to 91,000 ha (2016–2017). The contribution of litchi to the total area under fruit cultivation has increased from 0.75% to 1.70%. Increase in area during 1991–1992 to 2016–2017 (22 years) has been more than 80%, whereas production increase during the same period is to the tune of more than 150% (NHB, 2016–17). Productivity also recorded an increase of about 50% during the same period. Evidently, production and productivity of litchi are constantly increasing in the country. On a global scale, the fresh fruit market dominates the trade, followed by dried and canned fruit. Low success rate of establishment, lesser fruiting span, low and irregular yields because of poor flowering and fruit set, fruit cracking, browning and rotting of fruits, fruit borers and mites, poor shelf life, and lack of suitable varieties with early and late maturity and good-quality fruits are some of the factors encountered

1.1 Introduction Among the C4 grasses known as panicoids (subfamily: panicoideae), which also includes nutrient-rich cereals like millets and sorghum as well as commercially valuable crops like switchgrass, napier grass, and guinea grass, are bioenergy feedstocks like sugarcane and miscanthus. Among all, millets overpowered others in terms of biotic/abiotic stress resilience, resource sustainability as well as nutritional benefits. Minor millets, often known as nutritional cereals, are a type of small-seeded grains that are members of the Poaceae family. Up to 35 kinds of grass from 20 genera are well-known for being minor millets. Finger millet, foxtail, proso millet, barnyard millet, kodo millet, and little millet are the most significant small millets that are grown worldwide. India is the leading producer and consumer of millet crops and their products. The total area of small millets in India is around 1.63 m ha, with a production of 1.82 m tones during the year 2016- 17 (Annual progress report 2018-19, ICAR-AICRP on small millets).

Apterygotes

The Apterygota, which formerly included the other primitively wingless insects currently placed in the class Entognatha, are now restricted to the two orders Archaeognatha and Zygentoma, which in turn were formerly united as the Thysanura. Despite the superficial similarity of the two groups, it is now clear that they are not closely related, mainly because of fundamental differences in the mouthparts. The Archaeognathous mandibles are monocondylic, having a single articulating point with the head so that the mandible can rotate. The Zygentomous mandibles are dicondylic, with two articulating points that restrict the motion to a single plane yet enable the development of a much stronger biting action; this is the type found in all the higher insects, and the Zygentoma may well be the sister group of the Pterygota, or winged insects. Clearly the ‘Apterygota’ is not a monophyletic group and is simply retained for convenience in grouping these two orders that superficially resemble each other and have similar life histories.

Population: The word population or universe in statistics means a set of observations relating to a phenomenon under investigation.

Sample: It is a fraction or a subset of population drawn through a valid statistical procedure so that it can be regarded as representative of the entire population.

Sampling: The statistical procedure of drawing a sample from the population is called Sampling.

Census enquiry or complete enumeration: When each and every unit of the population is investigated for the characteristic under study, known as census enquiry or complete enquiry.

Sample enquiry or sample enumeration: It is a part of the population is investigated for the characteristic under study, known as sample enquiry or sample enumeration.

Necessity of sampling: Since, the process of collecting information from all the elements of a large population may be, in general, expensive, time consuming and difficult. We help to sampling and generalise the properties of the sample to the entire population. The statistical procedures which are used for drawing inferences or conclusions about the population from sample data are covered under Inferential Statistics or Statistical inference. Thus, sampling theory is the basis of statistical inference in which we wish to obtain maximum information about the population with minimum effort and maximum precision.

Bovine leukocyte adhesion deficiency (BLAD) is a lethal autosomal recessive disease caused by a point mutation in CD 18 gene. Through Minimum Standard Protocol (MSP), Government of India made mandatory to screen all the breeding and newly introduced HF bulls for this BLAD. In this present study screening for mutation is carried out by polymerase chain reaction-restriction fragment length polymorphism technique (PCR-RFLP). Non availability of positive control made us to resort for synthesis of DNA probes with similar sequence of the gene with mutation and authenticity was verified by nucleotide sequencing. A total of 200 blood samples collected from phenotypically normal HF bulls from organized farms and subjected to PCR-RFLP technique. The results indicate that out of 200 bulls, 01 bull (0.5%) was found to be carrier for mutated gene CD18. Hence it is mandatory to screen each bull to prevent accidental transmission of mutant gene to a large number of future populations.

Introduction

Neuroanatomy research covers a wide range of topics including, gross anatomy of brain and spinal cord, imaging technologies for diagnosis, surgical anatomy, microscopic anatomy on nervous system, ultrastructural details on neurons and neuroglia, research on gene and protein expression patterns using in situ hybridization and immunocytochemistry. Despite many challenges, neuroanatomy in animals remains a crucial area of study for understanding the basic principles of structural organisation and its physiology. This review on the master glands i.e. hypothalamus and hypophysis cerebri, is mainly focused on the histomorphology and ultrastructural details reported in rat, rabbit, sheep, goat, buffalo and camel.

Mastering the Master gland

The hypothalamus (“hypo” meaning below, and “thalamos” meaning nuptial chamber / innermost room) is a major centre of the brain consists of regulatory circuits that controls internal body functions for survival. The hypothalamus is a small, central region of the brain composed of a conglomerate of hypothalamic nuclei and their nerve tracts. The hypothalamic neural connections to the pituitary glands in various mammals have been studied under light microscopic examination of sections of hypothalamus and pituitary gland together intact with infundibular stalk (Paramasivan et al., 2011). The nerve fibres of various hypothalamic nuclei coursed on as a distinct bundle into the infundibular stalk and then continued into the neurohypophysis. Through its connections with pituitary gland, the hypothalamus exerts an enormous influence over the endocrine system and thereby over the general metabolic functions and reproduction (Clemente, 1985). The pituitary gland (hypophysis cerebri) is considered as the master endocrine gland as it plays a critical role in influencing and controlling the activities of other endocrine glands viz. thyroid, adrenal, ovary, testis and pineal. However, the hypophysis itself is under the control of the hypothalamus which actually masters the endocrine function of various hormones released from the master gland i.e. hypophysis cerebri.
