A pipe is connected to a tank or cistern. It is used to fill (inlet) or empty (outlet) the tank. Therefore, Inlet refers to a pipe which is connected to fill a tank is known as an inlet, while outlet refeRs to a pipe which is connected to empty a tank is known as an outlet. Generally the problems on pipes and cisterns are similar to problems on time and work. In pipes and cistern problems, the amount of work done is the part of the tank of filled or emptied. And, the time taken to do a piece of work is the time taken to fill or empty a tank completely or to a desired level. Following points should be remembered to solve the probles;

Multipurpose trees and shrubs are defined as all woody perennials that are purposefully grown to provide more than one significant contribution to the production and/or service functions of a land-use system that they occupy. In agroforestry systems, different species of trees and shrubs can be planted with many types of crops in a variety of patterns. Thus, it is required to know about the methods of propagation and nursery raising, planting and other silvicultural management practices along with the diverse uses of multipurpose trees and shrubs of tropical and subtropical areas before their selection for forestry and agroforestry activities. It is important to select the most suitable tree species since it is not easy to replace them once they have been planted.

MANGIUM (Acacia mangium)

Acacia mangium is a single-stemmed evergreen tree that grows to 25-35 m in height and up to 60 cm in diameter. The bole is usually straight, often fluted near the base, free of branches for up to half its height. Mangium is native to Australia, Indonesia and Papua New Guinea. However, it tolerates varied site conditions and has adaptability to different planting objectives. Mangium shows most vigorous growth on well-drained, fertile soils in high rainfall areas in the humid tropics. It is valued for its rapid growth and has been planted throughout the humid tropics and is a major plantation species in the Asia-Pacific. Provenances from Papua New Guinea consistently show better growth in height and diameter.

Introduction

Eradication of malnutrition and hunger (Sustainable Development Goal, SDG-2) are the major challenges to humanity. Availability of sufficient nutritionally balanced food is the prerequisite for ensuring global food security. Food security is also critical for achievement of SDG 1 (poverty eradication) and SDG 3 (health and well-being) (UNDP, 2019). Changing climatic conditions accompanied by global warming not only acts a major threat for achievement of SDGs but could actually lead to the reversal of the progress already made. The escalating global temperature has jeopardized the food security throughout the world. A great decrease in the global crop yield has been suspected even with a 2°C rise in temperature. On field, it is often associated with crop nutrient loss, less accumulation of micronutrients and low availability of micro-minerals like iron and zinc. Additionally, the effect of the rainfall and temperature has also been observed. The global food prices are projected to increase by 3–84% by 2050 due to the fluctuations in rainfall and temperature (Hoegh-Guldberg et al., 2018).

Millets are the small seeded grains which belong to family Grassacae/Poaceae. Traditionally, millets are used for the food and feed purpose and are among the oldest cultivated crops. The millet species of commercial importance are proso (Panicum miliaceum), foxtail (Setaria italica), barnyard (Echinochloa esculenta), finger (Eleusine coracana), little (Panicum sumatrense) and pearl (Pennisetum glaucum) in different regions of the world. In India, foxtail millet (priyangava), barnyard millet (aanava) and black finger millet (shyaamaka) have been mentioned even in the Yajurveda texts of 4500 BC (Morya et al., 2017). The records of consumption of foxtail and proso millet are as old as 2000 to 1000 BC in China. Cultivation of foxtail millet in Korean peninsula is documented around 3,500–2,000 BC. Foxtail millet is the oldest of all the cultivated millets and is believed to be originated in Southern Asia. From there, it was spread to Europian nations. In the west, cultivation of millets majorly started after 1850 (ICRISAT, 2019)

Plants are exposed to microbial pathogens at all growth stages from seeds to harvested produce. But they are resistant to numerous pathogens that are present in the environment and susceptible only to some of them. In other words, a plant species has built-in resistance mechanism to avoid or resist the invasion by many microbial pathogens. A pathogen may reach several plant species, but it can infect only a few plant species in the particular location or region. The process of pathogenesis or disease development is initiated when the pathogen reaches the plant surface that allows the initiation of infection. An organism is able to derive its nutrition from the susceptible host plant and becomes pathogenic. The physiological functions of such infected plants deviate from those of the healthy (normal) plants and suffer irreversibly to different magnitudes. The organism adversely affecting the plant growth and other functions to obtain nutrition is the pathogen. It develops rapidly or slowly in proportion to the levels of susceptibility / resistance of the host plant to the pathogen species concerned. Thus a plant species may be susceptible to some pathogens, while remains resistant / immune to other organisms that may be pathogenic to some other plant species. Depletion of compounds from the plants to meet the nutritional requirement of the pathogen leads to different kinds of external symptoms and internal changes due to derangement of normal metabolic functions of the host plant. The process of disease development in a susceptible host plant species is known as pathogenesis.

12.1 Assays for molecular diagnosis of Acute Myeloid Leukaemia (AML)

Acute Myeloid Leukaemia (AML), also known as Acute Myelogenous Leukaemia or Acute Myeloblastic Leukaemia or Acute Granulocytic Leukaemia or Acute non Lymphocytic Leukaemia is an aggressive type of cancer which affects blood and bone marrow. AML is a heterogeneous disorder if one considers its clinical status, therapeutic responses and overall prognosis.¹ This disease called acute because it progresses very fast and myeloid as it originates from myeloid cell line in the bone marrow.

In bone marrow blood cells are made in a controlled way. When AML occurs excess numbers of immature leukaemia cells are produced. Overproduction of leukaemia cells in bone marrow disables bone marrow to make mature white blood cells. These accumulated immature cells are unable to function properly (Inability to fight infection).

Diagnosis: Correct diagnosis is important for a successive treatment for AML. There are several tests available to diagnose AML but not all tests will be used for each person. The following tests may be used to diagnose AML.

ECONOMICS is the term derived from a Greek word ‘OIKOS’ means a HOUSE and NAMEN means TO MANAGE, i.e. to manage a household using limited funds available in most possible manners. The founders of Economics defined it as-‘The Science of Wealth’. In general, we may say that Economics is the social science that studies economic activities. Economists at different times have emphasized different aspects of Economic activities, and have arrived at different definitions of Economics.

Groundnut also known as peanut or monkey nut (Arachis hypogaea L. 2n = 4x = 40, allotetraploid, a species of the legume or bean family, Fabaceae, essentially self-pollinated, with genome 1C=2891 Mbp) is one of the five major oilseeds, namely, soybean, sunflower, groundnut, cottonseed and rapeseed. The global acreage, production and yield during 2018-19 have been 27.49 million hectares, 46.81 million tons and 1700 kg per hectare. The preliminary corresponding figures for 2019-20 have been 26.75 million ha, 45.87 million tons and 1710 kg per ha (USDA, 2000). India and China with more than 4.5 million ha each account for nearly one third of total global acreage and fifty percent of global production (China, 17 million tons and India, 6.69 million tons). Other countries in descending order in terms of area are Sudan, Nigeria, Senegal, Myanmar, Niger, Chad, Guinea, Uganda, Congo and Mozambique. Productivity-wise, USA tops the list (4480 kg/ha) followed by China (3750 kg/ ha). India with 1400 kg/ha is at the average position.

Biocompatible, biodegradable, intelligent and responsive materials are currently an emerging area of interest in the field of efficient, safe, and green pesticide formulation. Using nanotechnology to design and prepare targeted pesticides with environmentally responsive controlled release via compound and chemical modifications has also shown great potential in creating novel formulations. Special attention was paid to intelligent pesticides with precise controlled release modes that can respond to micro-ecological environment changes such as light-sensitivity, thermo-sensitivity, humidity sensitivity, soil pH and enzyme activity (Huang et al., 2018).

4.1. Introduction

Presently, in the world, there are 195 countries according to the United Nations, and the number would even go up to 247 if we consider the disputed territories like Isle of Man, Hong Kong, etc. (United Nations, 2016) (Kershner, 2020). But the majority of the countries are still struggling to provide basic life-supporting amenities like nutrition, shelter, and employment. Conjointly, termed as emerging and developing countries such as India, Vietnam, Venezuela, Utopia, etc. (Ahmed and Shimada, 2019). Most of the developing countries are situated mainly in the continent of Africa, Asia and South America. They have got independence for the European countries like England, France, Portugal and Spain in the mid and late 20th century.

Soil minerals are naturally formed inorganic compounds with definite chemical composition and characteristic geometric (crystalline) form. They are classified as primary and secondary minerals, silicates and non-silicates minerals, and crystalline and non-crystalline minerals. Primary minerals have not been significantly altered chemically since deposition or crystallization from molten magma and are usually found in the sand and coarse silt fractions. Secondary minerals form as a result of the alteration of primary minerals by weathering and are found in the clay and fine silt fractions.

There is no doubt that after independence, particularly during 1966-68, the use of hybrid and composite seeds of various crops, chemical fertilizers and pesticides resulted in an increase in the Indian agricultural output leading to ìGreen Revolutionî. But quite soon, the deleterious effects of farming based on chemical Organic Farming for Sustainable Agriculture 105 methods came to fore.

A system is a set of components that are interrelated and interact among themselves. A system may be natural, social or artificial. Natural systems consist
of all the materials both physical and biological and are independent of human beings. Our role in relation to natural systems is to try to understand these
systems and make use of them as per our needs. 

Integrated farming system is a multidisciplinary whole farm approach, which enables the farmers to identify opportunities and threats and act accordingly. It
is a dynamic approach which can be applied to any farming system around the world. It is very effective in solving the problems of small and marginal farmers.
The approach aims at increasing income and employment from small-holding by integrating various farm enterprises and recycling crop residues and by-products
within the farm itself.

Sampling for nematode communities has been the basis for the development of appropriate control strategy. The major purposes of sampling for nematodes include population estimation for general detection, advisory or predictive programme, disease diagnosis and also for research purposes.

Introduction to Energy Sources

Consumption of nonrenewable energy sources has caused more environmental harm than any other human activity during the last century. Electricity generated from fossil fuels like coal and crude oil has resulted in excessive levels of hazardous gases in the environment. As a result, several issues exist now, such as ozone depletion and global warming. Vehicle pollution has also been a significant issue.

As a result, alternative energy sources have become increasingly vital and relevant in today’s society. These sources, such as the sun and wind, can never be depleted and are hence referred to as renewable. They produce fewer emissions and are readily available locally. Their application has the potential to significantly reduce chemical, radioactive, and thermal pollution. They stand out as a promising source of infinite clean energy. These are also known as non-conventional energy sources.

Measurement of water used in irrigation ensures the application of required amount of water in crops. Knowing the rate of flow the adjustment to period of control at gates, etc. can be done to regulate the water at different branches of canals. To get the total control over the supply of water there should have the provision of water measurement at the critical points in irrigation systems.

Units of Measurement

Water is measured at rest or in motion. The water of reservoir, ponds, tanks, etc. at rest is measured in volumetric unit as liter, cubic meter, hectare-meter and hectare-centimeter. Water flowing in rivers, canals, channel, etc. is measured in litre/sec , liter per hour, meter per sec and hectare-meter per hour or day.

Introduction

There has been a steady increase in the poultry meat and egg production globally during the past few decades. Though the high biological value of eggs and poultry meat have resulted in an increasing demand for these two products, growing awareness for food quality and safety are becoming increasingly significant in determining the market value of such products. The importance of mycotoxins as one of the major detractor of poultry productivity and also of product quality, hence, becomes more relevant now than ever.

2.1 Rice

Rice is the staple food for the largest number of people on the Earth. According to an estimate, the global rice production must reach 800 million tonne from the present 91.04 million tonne in 2005-06 to meet the demand in 2025. It’s area is 37% of the total area under food grains as against 20% under wheat, another important food crop. But globally it stands next to wheat in harvested area. As the irrigated rice contributes more than 75 per cent of the total rice production, enhancing its yield potential would be key to meeting the global rice requirement for an additional 215 million tonne. To achieve the target yield, rice varieties with a yield advantage of about 20 per cent over popular and widely adapted rice varieties under tropical conditions must be developed. Experience in China, India, Vietnam, Philippines, Bangladesh and several other countries clearly indicates that hybrid rice technology offers readily available option to meet this challenge. 

Anatomy is the study of an internal structure of an organism, while morphology is the study of various external features of an organism Anatomy helps in knowing the structural peculiarities of different groups of plants, which help for adaptation to diverse environments. An angiosperm plant is characterized by the presence of roots, stems, leaves, flowers, and fruits

Plant cells: Plant cells are multicellular eukaryotic cells that make up a plant (a group of eukaryotes belonging to the Plantae kingdom, with the ability to synthesize their own food using water, sunlight and CO₂). Being eukaryotic cells, they have a defined nucleus with specialized structural organelles that enable it to function in an orderly manner.

There is no plant in this world which is uneconomical/not useful. Medicinal plants have been considered as important therapeutic aid for alleviating aliments of human kind. The WHO estimates that 80% of people living in developing countries rely almost exclusively on traditional medicines for their primary health care needs. Aromatic plants are used for essential oils - volatile material extracted from plants or plant parts usually by stream distillation and used in flavours and fragrances for food, soap, detergents, perfumes, lotions etc. Spices are the dry part of a plant such as roots, leaves and seeds which impart to food a certain flavour and pungent stimuli. Spices contain variable amount of fat, protein, carbohydrates, fibres, minerals and vitamins.

Mango (Mangifera indica Linn.) (Family-Anacardiaceae) is one of the most popular tropical and sub-tropical fruit crops in India and is well known as the “King of Fruits”. Mango is the national fruit of India and Pakistan as well as national tree of Bangladesh. It is cultivated worldwide in 49.46 lakh hectares with a production of 371.20 lakh tonnes. In India, the crop is cultivated in the largest area of 23.12 lakh hectares among all the countries in the world and production is around 150.30 lakh tonnes, contributing 40.48% of the total world production. India exports 59.22 thousand tonnes of mangoes to 40 different countries worldwide, valuing Rs. 162.92 crores (Anonymous, 2019).

Pheromones are neuronal signaling molecules synthesized by various organisms and then excreted into the environment, where they typically stimulate individuals of the same species to react to environmental changes (e.g., temperature shifts, biological stimuli, or nutritional changes) (Jun Young Park et al., 2019). It is thought that most organisms, from prokaryotes to higher animals such as humans, can produce and use pheromones for communication between nonspecific individuals. In most cases, pheromones trigger neuronal events that are linked to various behavioral responses. The outcome of such neuronal stimulation includes the modulation of developmental and/or physiological programs that can support adaptation to new environments. 

The insect body is made up of multicellular tissues. The body is bilaterally symmetrical and is covered by a hard, chitinous exoskeleton. The chitin at the junction of the segments is thinner and pliable and hence insects can bend their bodies. The exoskeleton is made up of several layers of non-living cells produced from the epidermis. Because of the hard chitin us exoskeleton of the body, the growth of the insect is affected beyond a certain extent. So, to facilitate further growth,, this exoskeleton is cast off a few times and this is known as ‘molting’. The number of moultings in a particular species is more or less constant.

3.1. Entrepreneurship and its allied concepts

3.1.1. Concept of entrepreneur

The word “entrepreneur” has its roots in the french verb “entreprendre,” which means “to undertake.” It means “to start a business” in a business environment. Entrepreneurs are self-employed individuals who not only create jobs for themselves but also generate jobs for many others. An entrepreneur is someone who can identify and seize opportunities to transform inventions or technologies into new products. They can also see an invention’s commercial potential and put together the funds, talent, and other resources needed to transform an idea into a product that can be distributed.

7.1 General Description

Shifting cultivation is a type of land use that dates back to the dawn of agriculture. It's done in places where forest resources are still plentiful. It usually refers to the gradual transformation of primary forests into a mosaic of secondary forests at varying stages of growth, rather than the complete abolition of forests. However, primary forest removal occurs gradually in order to preserve the same fallow time despite population development. As no primary forests remain (or as the remaining primary forests are entirely protected by local customs or conservation legislation), secondary forests fade away, and new techniques arise or are adopted, the fallow period shortens. Natural capital is gradually replaced by man-made productive capital, or the system approaches a state of crisis, depending on whether the limitations to these changes can be levered. In theory, the new land uses allow for more forest protection because they require less territory to provide the same output. In practice, they are triggered or triggered by a series of more radical changes, such as infrastructure development, migrations, financial investments, and new consumer habits, all of which frequently end in large-scale deforestation.

Solanaceae is a plant family that comprising of 2300 species and 85 genera of which, nearly one half of the species belongs to the genus Solanum. The genus Solanum includes both tuber bearing and tuber nonbearing forms. Among the tuber nonbearing forms, the major fruit vegetables growing throughout the world are tomato, brinjal and chilli. They prefer warm humid tropical climate for growth and development. Hence, the agroclimatic regions where this type of climate prevails is suitable for seed production of these vegetables. In addition to this, hybrid vigour has been widely commercially exploited in these crops because of easiness in emasculation and pollination and availability of large number of hybrid seeds per fruit.

Tomato (Solanum esculentum L.)

Tomato is the most important warm season vegetable growing throughout the world. The fruit is valued as salad vegetable and for cooking purpose. It is one of the vegetables from which, a wide variety of processed products are made. The crop is grown throughout the year in one part or other part of the country and it has become one of the indispensable fruit vegetables in our diet. It is rich in vitamin A, vitamin C, niacin, and minerals like calcium, phosphorus etc and it is rich in antioxidant, lycopene which is the carotenoid responsible for the red colour of tomato. Tomato is of recent origin, and it is the native of Peru in South America from where it spread to the entire part of the world.

Crop Water Requirements

In designing an irrigation system, the primary objective is to know the water requirement of crops. Water requirement of crops are determined either by f ield cultivation or by estimation through commonly used empirical formulae such as Blaney Criddle, radiation, Penman or pan evaporation method.

Definitions

Crop water requirement or evapotranspiration (ETcrop ): It may be defined as the rate of evapotranspiration of a disease free crop growing in a field of not less than one hectare under adequate fertility and water supply so that full productive potential can be achieved in prevailing environment. Evapotranspiration requirement of a crop refers the ETcrop and expressed in mm/day.

Reference crop evapotranspiration (ET0 ): It is the rate of evapotranspiration from an extended surface of 8 to 15cm tall green grass of uniform height, actively growing, completely shading the ground and not short of water. ET0 may be computed by using the empirical formulae and meteorological data for the specific period.

Introduction

A biopolymer is defined as a polymeric substance obtained from any living organism (plant or animal) [1]. These polymers are organic compounds where simpler molecules are covalently bonded with each other [2]. Although biopolymers are strictly synthesized naturally by living cells but some of them are also synthesized from non-biomaterial as well. Natural biopolymers are of different types based on their chemical nature like carbohydrate based, protein based or lipid based. Biopolymers can be broken down by the action of naturally-occurring organisms which leaves organic non-harming by-products like water and carbon dioxide in the environment[3].

Bio polymers are gaining importance in the field of food packaging, medical application, commodity packaging etc. because of their have specific physical, chemical, biological, biomechanical and degradation properties. Wide ranges of natural or synthetic biopolymers capable of undergoing degradation hydrolytically or enzymatically are being investigated for many applications[1]. Bio polymers are mainly based on two properties: a) Biological origin b) Biodegradability.

Earlier natural biopolymers such as cellulose, protein, starch have been used extensively for food applications. Recently, synthetic biopolymers such as polylactic acid (PLA), polycaprolactone (PCL), polyglycolic acid (PGA), polyvinyl alcohol (PVOH), and polybutylene succinate (PBS) are gaining more attention[4] for various applications. Natural biopolymers are more stereospecific and mostly hydrophilic having complex 3D structures as compared to the synthetic polymers[2]. Among the synthetic biopolymers some are microbiologically degradable in the environment whereas some are recyclable[1].

It is vital to categorise agroforestry and its many systems in accordance with certain contemporary standards in order to have a thorough grasp of them and to enable future progress. Since each agroforestry system refers to a different set of agroforestry practices involving agriculture (crops), forestry (trees), and pasture (animals), the various uses of land are combined either temporally or spatially. Each agroforestry system has its own unique arrangement of various components, such as crops, animals, perennial trees, etc., and degree of interaction between the components. In terms of structure, composition, age intensity, technology, inputs, etc., one system varies from the other.

Creating a useful framework for the synthesis and analysis of data on current systems as well as the creation of new, promising ones should be the primary goal of classification. For this reason, every categorization system needs to have the accompanying the following standards.

All agroforestry systems are characterized by three basic sets of attributes; productivity, sustainability, and adoptability (Nair, 2008).

Productivity: The majority of agroforestry systems, if not all of them, strive to maintain or raise both land productivity and output (of desired commodities). In several aspects, agroforestry may raise production. These include higher yields of related crops, less input use in the cropping system, enhanced labour efficiency, and higher production of tree products.

Sustainability: Agroforestry can achieve and indefinitely maintain conservation and fertility goals by conserving the production potential of the resource base, mainly through the beneficial effects of woody perennials on soils.

Adoptability: Improved or new agroforestry technologies that are introduced into new areas should fit the social as well as environmental characteristics of the land use system for which it is designed and should also confirm to local farming system.

Multipurpose trees and shrubs are defined as all woody perennials that are purposefully grown to provide more than one significant contribution to the production and/or service functions of a land-use system that they occupy. In agroforestry systems, different species of trees and shrubs can be planted with many types of crops in a variety of patterns. Thus, it is required to know about the methods of propagation and nursery raising, planting and other silvicultural management practices along with the diverse uses of multipurpose trees and shrubs of tropical and subtropical areas before their selection for forestry and agroforestry activities. It is important to select the most suitable tree species since it is not easy to replace them once they have been planted.

MANGIUM (Acacia mangium)

Acacia mangium is a single-stemmed evergreen tree that grows to 25-35 m in height and up to 60 cm in diameter. The bole is usually straight, often fluted near the base, free of branches for up to half its height. Mangium is native to Australia, Indonesia and Papua New Guinea. However, it tolerates varied site conditions and has adaptability to different planting objectives. Mangium shows most vigorous growth on well-drained, fertile soils in high rainfall areas in the humid tropics. It is valued for its rapid growth and has been planted throughout the humid tropics and is a major plantation species in the Asia Pacific. Provenances from Papua New Guinea consistently show better growth in height and diameter.

1. Introduction

The advent of computers, the Internet and other ICT technologies have enhanced the nature of tasks. No one is immune from technology. Technologies have paved the way for information transformation. Today every section of society is making full use of technologies to fulfil their needs. Electronic devices have affected human life to a great extent. These devices have changed the working styles of human beings. Working with electronic devices is much better than manual work. Therefore, every sector of human working society is updating itself by using or implementing electronic devices. The higher education department is no exception to this. Today every sector of higher education department is using these modern tools and technologies not only for official works but also for teaching. Library is the most important part of Higher Education Institutions and today the entire structure of the library has changed. Today computersare being used in every section of the library and the main work of the library- issue/return is also being done through the use of computers and the Internet. The resources available in the library have also become electronic. Every resource like books, magazines, research journals, dictionaries, glossaries, bibliographies, biographies, who’s who etc, is now being published in electronic form and the library has to purchase these resources for its users.

Soil colloidal substances are composed of very fine particles (< 0.002 mm diameter) that undergoes two phase system in a heterogenous manner, where, one phase (disperse phase) is disperse in a fine state of subdivision in another medium called dispersion medium. The soil colloidal properties are affected by the physico-chemical and biological parameters of soils. The availability of plant nutrients are governed mostly by the surface charge characteristics of clay colloids.

5.0 Soil Colloids

Soil colloids being one of the active constituents determine the physical and chemical properties of the soil with the diameter ranging from 1 μm to 2 μm. The origin of the particles may be organic and inorganic constituents.

Programming techniques are used the mathematical tools by the scientists, economists, and planners to specify the optimum combination of resources and enterprises in farms and firms, to identify the profit maximizing mixes of commodities to be produced, to specify the cost minimizing methods of production and transportation of goods, to identify the least cost locations from which raw materials can be purchased, to determine the locations of production at which a particular commodity should be produced and the consumption centres to which it should be shipped, and to specify the least cost ingredients of a feed or ration which must meet the specified nutritional requirements. Programming techniques can be either linear or non-linear. Although several non-linear programming techniques (like quadratic, integer, separable, dynamic programming, etc., which are very complex to work with) are available, we will largely deal with linear programming technique and to a certain extent will brief the theory of dynamic programming.

Project managers need to make sense on the many data that they have. Analytical tools are used in project management to achieve such need. Such tools are used to create a forecast of potential outcomes based on the variations present in the environmental and project variables. There are different types of analytical tools used and one of the most common tools is regression analysis.

14.1. Multiple Regression

Concept: Multiple regression is the most commonly utilized multivariate technique. It examines the relationship between a single metric dependent variable and two or more metric independent variables. Multiple regressions are often used as a forecasting tool. Goal is to use the linear composite of two or more continuous and/or categorical variables (predictors) to: 1) predict scores on a single continuous variable (criterion), or to 2) explain the nature of the single continuous criterion variable from what is known about the predictor variables. In prediction, the criterion is the main emphasis because decisions are made on its value, but often times, it is difficult to directly measure or obtain a subject’s actual score on the criterion; therefore, it is important to estimate or predict one’s criterion score based on the value of the predictor scores.

Project management involves the use of knowledge, skills, tools, and techniques to design activities to fulfill project requirements. In other words, project management encompasses the skills, tools and management processes needed to successfully implement a project.

Project Management comprises

• Skill. Expert knowledge, skills and experience are necessary to reduce the risk level of a project and thereby enhance the likelihood of its success.

• A set of tools. Project managers use a variety of tools to improve their chances of success. Examples include document templates, records, planning software, modeling software, inspection checklists and inspection forms.

• Sequence of processes. Various Management methods and procedures are necessary to oversee and regulate the time, cost, quality and scope of projects. For example, time management, quality management, cost management, change management, problem management and risk management.

Project Management is adequate when or when should you use project man agement techniques

Introduction

Vitamins are the organic derived accessory food factors apart from carbohydrate, lipid and proteins meant for specific biological functions, optimum growth and health of an organism. These factors are are required in minute amount in the diet for proper functioning of biological enzymes. The term accessory factors were given by Hopkins to the essential nutrients present in the natural foods. Funk (1913) coined the term vitamine to the active principal present in rice polishings. Vitamins are classified into two categories like fat soluble A and water-soluble b Vitamins A, D, E, K are fat soluble whereas Vitamins B and C are water soluble. The B group of vitamins include vitamin B1, B2, B6, biotin folic acid, B12 etcall the fat-soluble vitamins are isoprenoid in nature consisting of repeating isoprenoid units. And meant for diversified functions. The water-soluble vitamins are heterogenous group of compounds generally not stored in the body and readily excreted in urine. These are mostly act as coenzymes for the vital biological enzymes deficiency of which reflects in the form of various deceases.

Vitamin A, include retinoid group of compounds like retinol, retinal and retinoic acid Retinol is a primary alcohol containing β-ionone ring with isoprenoid units, double bonds and hydroxyl group. Naturally it exists as ester of long chain fatty acids. Retinal is the aldehyde form whereas Retinoic acid is the acid form. Carotene is provitamin A normally found in plant origin foods that in the intestine gives rise to two moles of retinal by enzyme carotene 15-15-dioxygenase. Diet contains retinol esters and p-carotene. Retinol esters are hydrolyzed into fatty acids and retinol that absorbed into intestinal mucosal cells. p-carotene Is absorbed and converted into retinal by p-carotene dioxygenase. Retinal then converted into retinol. In the intestinal mucosal cells, retinol re-esterifies with fatty acid to form retinol ester.

Introduction
India has a well-established fisheries and aquaculture industry that significantly impacts Gross Domestic Product (GDP), foreign exchange, and nutrition. The fisheries sector plays a crucial role in India’s economy, contributing approximately 1.07% to the national GDP and 6.72% to agricultural GDP in 2021-22 (Economic Survey, 2022). India is second-largest producer of fish in the world (after China), with an annual production of around 16.24 million metric tonnes (MMT) in 2022–23, comprising 12.2 MMT from Inland fisheries and 4.04 MMT from marine fisheries. The fisheries sector has experienced remarkable growth over the decades. Fish production surged from 0.75 MMT in 1950-51 to 12.59 MMT in 2018-19, marking a seventeen-fold increase. This growth has been accompanied by a rise in the sector’s contribution to agricultural GDP, which impressively increased from 0.84% in 1950 to 5.7% in 2017. India is one of the largest seafood exporters, with exports reaching INR 63,969 crores ($8.09 billion) in 2022-23 (Marine Products Export Development Authority - MPEDA). Frozen shrimp is the leading export commodity, followed by frozen fish and cephalopods. The USA, China, the EU, and Southeast Asian nations are key export markets. This robust performance underscores the sector’s role in bolstering India’s foreign exchange reserves. The sector supports direct employment to over 28 million people, mainly in coastal and rural communities (National Fisheries Development Board, 2023) and indirect employment, including processing, transportation, and allied workers.
Fish is an important source of protein, essential fatty acids, vitamins and minerals. The harvest, handling, processing and distribution of fish
provide livelihood for millions of people and also provide valuable foreign exchange earnings. In both the industrialized and developing countries, fish is an important and cheaper source of animal protein to local communities (Adewolu and Adeoti, 2010). Fish is also used as source of other nutrients such as micro nutrients, minerals, and essential fatty acids mainly in the Low Income Food Deficit Countries. However, the disadvantage with the fish is that it is highly perishable though it is an inexpensive protein source. Due to these characteristics, the fish suffers 50-60% higher post harvest losses compared to agricultural commodities.

Introduction
Aquaculture is rapidly outpacing all other sectors in agricultural development. The study of fish genetics gained traction in the 20th century, driven by advancements in the understanding of Inheritance and reproduction. During the 1960s, selective breeding programmes aimed at enhancing genetic qualities became more common (Gjedrem and Baranski, 2009). Currently, more than 60 fish and shellfish species are going through selective breeding (Gjedrem and Baranski, 2009). Despite this, many critical traits like resistance to disease, efficiency of feed conversion, fatty acid composition and quality of meat are challenging to assess in breeding prospects but significantly impact the yield and profitability of several aquaculture species. Genetic mapping refers to the process of creating a genetic map (Van Ooijen and Jansen, 2013). Making genetic linkage maps is still essential for carrying out genetic and genomic research and many aquaculture species have had such maps developed. Developments in genotyping and sequencing technologies have made it the creation of higher-density, high-resolution (HR) genetic linkage maps. However, there are now important tasks in linkage analysis due to the usage of a large number of molecular markers. High-density linkage maps are valuable tools for studying genomic biology and evolutionary genetics because they serve as the foundation for QTL (quantitative trait loci) mapping. They facilitate the quantification of recombination rates, linkage disequilibrium levels, and chromosomal rearrangements across chromosomes, between sexes, and among different populations. The development of marker-Assisted Selection (MAS) has gained significant consideration and has significantly accelerated genetic breeding efforts in numerous cultured aquatic organism (Li, 2019; Yu, 2019). Quantitative trait loci (QTL) linked to economically important variables are frequently mapped using genetic linkage maps, which are an invaluable tool for examining genomic regions. (Huang, 2020; Wan 2017; Zhou, 2021). Growth rate, flesh quality, and disease resistance are only a few of the important features that are regulated by several genes or loci. The use of genetic maps in QTL (quantitative trait loci) mapping is essential for determining the locations of genes linked to these traits. (Huang, 2020; Li, 2019; Wan, 2017; Wang, 2018). The mapping of trait-related quantitative trait loci has been greatly improved by recent developments in high-throughput next generation sequencing techniques (You, 2020). Research in this field has greatly advanced through the use of a variety of techniques, including restriction site-associated DNA sequencing (RAD-seq), genotyping-by-sequencing, specific-locus amplified fragment sequencing, and genome-wide association studies (GWAS). Of these, RAD-seq is thought to be an appropriate, robust, and economical approach that has demonstrated 172 Aquaculture Genetics: Breeding, Conservation, and Sustainable Production efficacy in detecting genotypes and single nucleotide polymorphisms (SNPs) (Andrews, 2016). Linkage mapping in aquaculture is a valuable tool that has revolutionized selective breeding. By revealing the genetic foundations of key traits, it allows for more efficient and sustainable aquaculture practices. The integration of linkage mapping with other genomic technologies is expected to enhance productivity, improve disease management, and ensure the long term sustainable growth of aquaculture industries worldwide.

1. Introduction
In the realm of modern agriculture, achieving sustainability is paramount. The judicious use of resources and the maintenance of soil and crop health are vital components of this endeavor. Remote sensing is a powerful technique used to gather information about the Earth’s atmosphere and surface without direct physical contact (Lillesand et al., 2015). It involves the acquisition, measurement, and analysis of data from sensors aboard platforms such as satellites, airplanes, drones, or ground-based instruments. These sensors record electromagnetic radiation, providing valuable insights into various aspects of the Earth’s environment. Remote sensing technology has emerged as an invaluable tool for achieving these objectives, offering a range of benefits for sustainable agriculture (Jensen, 2009). With the advent of modern technologies such as hyperspectral remote sensing (HRS) that collects information in narrow contiguous bands, many new avenues of applications have come up. This detailed spectral information enables the precise identification and classification of objects based on their unique spectral signatures. Further, the narrow spectral reflectance provides significant information regarding the biophysical, biochemical, and physiological parameters of crops. These characteristics of HRS provides opportunities for improved feature identification, anomaly detection, and quantification. Often HRS data also complement to the remote sensing data, such as LiDAR or SAR (Synthetic Aperture Radar), allowing for a more comprehensive understanding of the Earth’s surface and its features. All these features of HRS enables precision agriculture, allowing the management practices as per the specific needs of the fields. By assessing soil and crop conditions remotely, one can apply resources like water, fertilizers, and pesticides precisely where and when they are needed. This minimizes waste and reduces the environmental impact of agricultural operations. Hyperspectral remote sensing can also assess critical soil parameters such as moisture content, pH levels, and nutrient concentrations. Monitoring these factors over time helps farmers make informed decisions about soil management and the choice of suitable crops. It also aids in preventing soil degradation and erosion. Early detection of stressors like pests, diseases, and nutrient deficiencies is crucial for maintaining crop health and maximizing yields. Remote sensing provides a timely and accurate means of monitoring crop conditions across large areas, enabling rapid responses to threats and reducing yield losses. In regions with water scarcity, efficient water management is essential. Remote sensing can track soil moisture levels and assess irrigation needs. By optimizing irrigation practices, farmers can conserve water resources while maintaining crop productivity. Remote sensing, particularly hyperspectral remote sensing can detect changes in

Introduction
Currently, about 350,000 species of flowering plants have been described under global flora, but only a few of them have been rigorously screened for plant breeding parameters and systematic research accomplished in terms of varietal development. According to the Great Medical Encyclopaedia, medicinal plants are those used as a source of raw material for preparation of medicinal products of natural origin. Medicinal and aromatic plants occupy a pivotal position in the socio cultural, health care and spiritual arena of rural people of India. Medicinal plants contribute significantly to the rural livelihoods for their sustenance and income generation. Medicinal and aromatic plants are being used since ancient time for the treatment of many diseases in traditional and recognized systems of healthcare and for therapeutic, fragrance and flavoring products in pharmaceutical and cosmetic industries besides as sources of natural dye, fat, essential oil, biopesticide, resin, protein, vitamin, condiment, spice, timber, fiber and other useful substances. Medicinal and aromatic plants-based livelihood systems are often mediated by the market forces and/ related directly to employment and income of the poor people.
Based on the research work carried out by International Development Research Centre (IDRC) in South Asia, MAP and other biodiversity-based livelihoods can not only become poverty alleviating but also been made socially equitable and gender balanced. According to the World Health Organization, 80% of people from developing countries depend mainly on traditional medicine for primary health care. India is one of the worlds’ richest sources of medicinal plants comprising of nearly 45,000 species, of which nearly 100 species find major commercial use as per the statistics of National Medicinal Plant Board, New Delhi. In 2017, the estimated global market value of herbal medicine and herbal supplements was in the region of $107 billion (Yao et al, 2019), and not surprisingly, the substantial demand and consumption of these products have resulted in shortages, and in some cases even the exhaustion, of several medicinal plant resources, leading to habitat destruction and the loss of genetic diversity.
Plant secondary metabolites specific to each medicinal herb are derived from the precursors obtained from the primary metabolic processes related to one plant species or related group of species. These metabolites protect plants against plants being eaten by herbivores or being infected by microbial pathogens. They serve as attractants for pollinators and as agents of plant-plant competition and plant microbe symbioses. The rise of chemical taxa of medicinal and aromatic plants can be considered as consequence of biochemical and metabolic processes mostly under genetic control. It is assumed that differentiation of cell is mostly manifested in chemo-differentiation at a molecular level and the fundamental differences of protein present in an organism, between different enzyme systems. Moreover, the identity of a medicinal plant is attributed to the dissimilarities in their metabolic profiling intra specific chemical adaptations influenced by the ecological and geographical conditions. This discrete chemical difference is known as poly chemism that occur in autogamous species like medicinal and aromatic plants

The genetic blueprint contained in the nucleotide sequence can determine the phenotype of an individual. The hereditary units, which are transmitted from one generation to the next generation are called genes. A gene is a fundamental biological unit like atom which is the fundamental physical unit.
Mendel was the first scientist who proposed genes as particulate units and called them hereditary elements or factors. But the concept of gene has undergone a considerable change since Mendel’s time.
Modern Concept of Gene
A gene can be described as a polynucleotide chain, which is a segment of DNA. It is a functional unit controlling a particular trait such as eye colour. Beadle and Tatum concluded by various experiments that gene is a segment of DNA that codes for one enzyme. They proposed one gene-one enzyme hypothesis. But as some genes code for proteins that are not enzymes, the definition of gene was changed to one gene-one protein hypothesis.
Protein Hypothesis
The concept of gene has undergone further changes as the new facts came to light. Since proteins are polypeptide chains of amino acids translated by mRNA, gene was defined as one gene-one polypeptide relationship.
Some proteins have two or more different kinds of polypeptide chains, each with a different amino acid sequence. They are products of different genes. For example, hemoglobin has two kinds of chains a andß chains, which differ in amino acid sequence and length. They are encoded by different genes. Thus, gene is defined as one gene- one polypeptide relationship.

Clinical Pharmacy
Definition of Clinical Pharmacy
Clinical pharmacy is a health science discipline in which pharmacists provide direct patient care to optimize the use of medications, promoting overall health, wellness, and disease prevention. It focuses on the application of pharmacological knowledge to enhance patient outcomes through individualized medication therapy management. According to the American College of Clinical Pharmacy (ACCP), clinical pharmacy incorporates comprehensive medication management, ensuring that drug therapy is safe, effective, and tailored to each patient’s unique health needs. The practice bridges the gap between pharmacy and clinical medicine by incorporating aspects of pharmaceutical care, patient counseling, and collaborative practice with healthcare teams.

Scope of Clinical Pharmacy
The scope of clinical pharmacy extends beyond traditional roles of drug dispensing and includes various patient-centric activities aimed at improving healthcare delivery.

Key Components of Clinical Pharmacy Include
1. Medication Management
• Therapeutic Evaluation: Clinical pharmacists evaluate medication regimens, ensuring that patients receive the correct drug at the appropriate dosage, route, and frequency.
• Monitoring Outcomes: Regular assessment of the patient’s response to treatment, including efficacy and safety, allows for timely adjustments.
• Preventive Care: Pharmacists identify and mitigate potential medicationrelated problems before they arise, such as adverse drug reactions and interactions.
