Introduction

Indian forests are being denuded at an appalling rate of 1.5 million ha per year but only a tenth of this is being renewed. This has resulted in the accelerated dwindling of forest resources to a meager level of 23.55 per cent of the total geographical area against the mandated requirement of 33 per cent. This low forest cover coupled with poor productivity (0.5 -0.7 m³ ha-1 yr^-1) in comparative global statistics (2.1 m³ ha-1 yr^-1) of Indian forest has ushered in a total mismatch between supply and demand of both domestic and industrial wood besides creating environmental de- stability and disequilibrium. The National Forest Policy of 1988 has resolved to phase out the supply of raw material to wood based industries and ultimately totally stopped the raw material supply from the forest (Anon., 1988). The policy also indicated that wood based industries have to become self reliance in meeting the raw material demand by establishing direct linkages with the farmers by providing lending facilitates and other input needs. This is going to pave the way for a strong industry-farmer nexus, with many farmers attracted towards tree husbandry due to assured marketability and income. As the activity gets intensified, location specific problems warranting solution are also found to be in the ascendancy.

Contracted Leg in Calves

Definition

A shortening or contraction of the deep and superficial digital flexor tendons and associated muscles, sometimes also the carpal flexors, leading to abnormal flexion of the fetlock, possibly also of the pastern and carpal joint.

Contrast radiography: The radiographic technique which employ the use of contrast media to identify a soft tissue structure or an organ and pathological findings which may be difficult or even impossible to visualize clearly in plain films due to lack of contrast with surrounding tissue is known as contrast radiography. This is a special radiographic techniques/procedures may be required to supplement or confirm the information obtained from plain or survey radiography. 
The substances used for this purpose is called contrast agents/medium/materials.

Abstract

Amongst various oilseed crops grown across the world, soybean (Glycine max L. Merrill) is globally important as a high source of protein and oil for human consumption and is also being used as potential feed for animals. Soybean is grown under rain-fed conditions in the tropics and subtropics in the marginal lands with less amount of external application of chemical fertilizers. The frequent climate variations have created a number of biotic and abiotic stresses, drought being a major abiotic stress which adversely affects the soybean productivity. Thus, to enhance the productivity of soybean, besides managing the nutrients, stress management is of utmost importance. There is a great opportunity of application of microbes especially arbuscular mycorrhizal fungi (AMF) where its application alone or in combination with plant growth promoting rhizobacteria (PGPR) can help in nutrient mobilization and remediation of plant stresses.

SYNOPSIS

Food security is a complex issue, linked to availability and access to food, malnutrition in the population, economic development, environment, and local and global trade. Malnutrition hinders healthy growth and proper development of the human immune system affecting neurological and cognitive development especially in children.

Livestock sector may be considered as a driving force for nutritional security and an important component of sustainable agriculture in India. Livestock sector besides providing milk and meat also provides a diverse range of output for agriculture (manure, draught power and transport) and for manufacturing sector (fiber and leather). According to estimates of the Central Statistics Office (CSO), the value of output from livestock sector at current prices was about 4,59,051 crore during 2011-12 which is about 24.8% of the value of output from total agricultural and allied sector at current price and 25.6% at constant prices (2004-05). The value of output of milk is 3,05,484 crore in 2011-12, which is higher than the value of output of paddy and wheat. The value of output from eggs and wool group is 17,803 crore and 318 crore respectively for 2011-12. Livestock agriculture is the only way to produce food in many of the world’s harshest environments. Locally adapted breeds enable these vast areas to be used in a sustainable manner.

Abstract

Wild medicinal plants have been major source of therapeutic agents for alleviation or cure of human diseases since time immemorial. These are extensively utilized throughout the world in two distinct areas of health management i.e., modern medicine and or folk medicine. Some of the important medicinal plants grown and cultivated in India for medicine, phytochemicals, nutraceuticals, cosmetics and others are Abelmoschus moschatus, Aristolochia bracteata, Cassia alexandrina, Caralluma fimbriata, Gymnema sylvestre, Withania somnifera and other species. They have become important sectors of trade and commerce. However, in India, about 90% collection of medicinal plants is form wild source and since 70% of collections involve destructive harvesting, many plants have become endangered or vulnerable or threatened. The increasing demands of the pharmaceutical industry have created problem of supply and one of the major difficulties being experienced by the industry is that of obtaining sufficient quantities of medicinal plants for the manufacture of genuine medicine.

Introduction

Livestock sector plays a significant role in the Indian economy, particularly for the welfare of rural population of India. The importance of livestock in India's economy can be gauged from the fact that 90 million farming families rear over 90 million milch animals. Of the total household in the rural areas, about 73 percent own some form of livestock, three-quarter of which are reared by small and marginal farmers.

Today, the overall growth rate in livestock sector is steady and is around 4-5%, despite the fact that investment in this sector is not substantial. This is possible due to the egalitarian distribution of the livestock as compared to land among landless labourers, small and marginal farmers thus resulting in balanced development of the rural economy particularly in reducing the poverty especially among the weaker sections of the society. Livestock also plays an important source of employment in rural India, especially for women. The rural woman plays a significant role in most of the animal husbandry operations related to feeding, breeding, management and healthcare of the livestock.

Livestock plays an important and vital role in providing nutritive food to families both in rural and urban areas. Since the dawn of civilization, mankind has been utilizing different animal species for a variety of purposes, viz., production of milk, meat, wool, egg and leather, draught power, companionship, entertainment, research experimentation, sports, security, etc. Livestock wealth is deemed to be as the oldest wealth resource for mankind and was once a symbol of economic status in the society. This is one sector where poor contributes to the growth directly instead of getting benefit from growth generated elsewhere. The effect of livestock sector growth on poverty is anecdotal, yet scattered evidence on livestock's contribution to income indicates that growth in livestock production is pro-poor.

Abstract

Most dryers operate at low thermal efficiency. The development of models and control systems offers an opportunity to improve dryer operation and efficiency. Dryer control is very important and with deeper understanding of the drying concept, new “smart” dryers can be made more reliable and more cost-effective than classical dryers. This chapter will provide an overview of necessity of control and safety measure in food drying system, and terminology related with drying control system. Different control strategy includes conventional and advanced techniques implemented in drying operation are reviewed  here and simple outline of intelligence control system in drying technology are briefly described in succeeding section. Various hazards in drying process and risk and safety management will also be discussed.

Introduction

The strategic control process is an essential component of strategic management that helps organizations monitor and evaluate their strategic plans and initiatives. It involves a systematic approach to assess the progress performance, and effectiveness of strategic objectives and make necessary adjustments to ensure alignment with organizational goals. Here are some key points on the introduction to the strategic control process. Strategic control refers to the ongoing monitoring, evaluation, and adjustment of an organization's strategic activities to ensure they are in line with the desired outcomes and objectives. It The significance of strategic control lies in several key reasons. helps organizations track their progress, identify deviations from the intended course, and take corrective actions. It also enables managers to assess the effectiveness of strategies, make informed decisions, and enhance organizational performance.

The economic loss in livestock arising due to mycotoxicosis is enormous apart from being a health risk. Indian economy is heavily affected by mycotoxins. It was estimated that 10 million dollars were lost in India’s export within a decade due to groundnut contamination with mycotoxins (Vasanthi and Bhat, 1998). Many developing countries have realized that reducing mycotoxin contamination in foods will not only improve the health and production in animal, but also increase the raw material exports (international trade) to other countries. The following strategies are to be adhered strictly to reduce the mycotoxins contamination of crops in the field.

1. Early harvesting

Early harvesting reduces the fungal infection of crop in the field. Early harvesting and threshing of groundnuts results in lower aflatoxin levels and higher gross returns of 27% than in delayed harvesting (Rachaputi et al., 2002).

Sterilization refers the complete removal or elimination of microorganisms from an environment. Physical and chemical agents are available to remove the microorganisms from the environment. Heat, irradiation and filtration are the three physical agents and various chemicals are available for sterilization.

Terms related to control of microorganisms

Cide or cidal means to kill the microorganism (Ex. Bactericidal refers the killing of bacteria).

Static or stasis means inactivation or inhibition, but not killing. They prevent multiplication of the organism. (Ex. Fungistatic refers the inhibition of growth of fungi.).

Sepsis refers break down of a living tissue by organisms and is accompanied by inflammation and pus formation.

Antispetic is an agent applied externally on living tissues to kill or inhibit the growth of the organisms.

Disinfectant is an agent applied externally on inanimate objects (not living tissues) to destroy harmful pathogens in their vegetative stage.

(Antiseptics are milder than disinfectants because to avoid the side effects)

Sanitation refers removal of organisms from a location by cleaning but not by sterilization.

Plant diseases create challenging problems in commercialagriculture and pose real economic threats to bothconventional and organic farming systems. Plantpathogens are difficult to manage for several reasons.First of all, plant pathogens are hard to identify becausethey are so small. The positive identification of apathogen often requires specialized equipment andtraining, and in some cases accurate diagnosis in thefield is difficult.Plant pathogens are constantly changing and mutating,resulting in new strains and new challenges togrowers. Disease management is complicated by the presenceof multiple types of pathogens. For any crop thegrower must deal with a variety of fungi, bacteria, viruses,and nematodes. This situation is even more complicatedfor organic crop production because they usuallyproduce a wide array of crops and are prohibitedfrom applying conventional synthetic fungicides.The world market continues to be extremely competitiveand continues to require that growers supplyhigh-quality, disease-free produce with an acceptableshelf life.

Fruits are living commodities which continue to respire and transpire even after harvest. The storage life of fresh fruits is indirectly proportional to the rate of their respiration which in turn depends on the atmospheric gas composition in which they are stored. Normal air contains about 20.9% oxygen (O2), 78.0% Nitrogen (N₂) and 0.03% carbondioxide (CO₂). Lower levels of O₂ and higher levels of CO₂ in the storage environment result in reduced rate of respiration, delayed ripening and increased storage life. The reduction in O₂ concentration and increase in CO₂ concentration in the storage room with precise control and maintenance of these gases throughout the storage period is generally referred as controlled atmosphere (CA) storage.

CA storage is generally used for long term storage or long distance transportation of fruits in combination with low temperature storage. The use of CA storage for extending the post harvest life of fruits has increased steadily worldwide during the past 60 years. This trend is expected to continue with the advancement of technologies in attaining and maintaining CA during transport, storage and marketing of fresh fruits.

Introduction

Perishable nature of horticultural produce is a major factor contributing in high post-harvest losses. The metabolic processes such as respiration, transpiration, and ethylene production remain active after the harvesting of produce, which drive ripening and senescence Fig. 1. Thus, an effective post-harvest handling is crucial to delay these changes. The rate of these processes depends on the produce’s physiological characteristics, composition, and storage conditions like temperature and humidity. Low-temperature storage is the simplest and most efficient method to slow down deterioration Escobedo-Avellaneda and Welti-Chanes, 2016. Combining low temperatures with methods that limit oxygen exposure, which fuels many enzymatic reactions, further extends shelf life and maintains food quality. Reduced oxygen levels decrease respiration and the activity of enzymes like polyphenol oxidase and peroxidase.

Introduction

Nitrogen (N) fertilization assured centre stage for enhancing food production in developing countries especially after the introduction of high yielding and fertilizer responsive crop varieties. Almost half of the human population relies on N fertilizer for food production (Ladha et al., 2005), and about 56 percent of the N fertilizer is used for producing rice, maize, and wheat (IFA, 2002). It has contributed an estimated 40% to the increase in per capita food production over the past 50 years (Smil, 2002). However, excess use of chemical N fertilizer may negatively affect surface water, as well as groundwater, and the atmosphere (through leaching and runoff) through volatilization of N (Galloway et al., 2008).

Control means the power or authority to direct and order or restrain. In the context of an entrepreneurial function, control may be defined as “comparing operating results with the plans, and taking corrective action when results deviate from the plans”.

Control requires two things: first, there is a clear – cut and specific plan according to which any work is to proceed and second, it is possible to measure the results of operations with a view to detecting deviations.

Components of biodiversity are all the various forms of life on Earth including ecosystems, animals, plants, fungi, microorganisms, and genetic diversity. Ecosystems, species and genetic resources should be used for the benefit of humans, but in a way that does not lead to the decline of biodiversity. Substantial investments are required to conserve biodiversity, but it will bring significant environmental, economic and social benefits in return. To address these challenges various initiatives were taken in the past such as Ramsar Convention on Wetlands in 1971, Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) in 1973, 1979 Bonn Convention on Migratory Species (CMS) in 1979.

The ever mounting population in 21^st century is a great challenge for the researchers to provide ample food and that has to be achieved within the context of existing challenges such as deteriorated arable land along with increasing adverse affects of changing climate. There is demand to increase food production to the tune of 70% by 2050 (Wani and Sah, 2014). Although major crops have achieved good progress, vulneRability to climatic variability emerged as a serious concern in crop improvement which could be attributed to higher sowing densities that in turn lead to more competition for water and nutrients. Abiotic stresses can be considered as major yield restraining factors among different crops. The projected estimations for changes in abiotic stresses such as drought, water logging and heat reveals far serious concerns for crop productivity (Qin et al., 2011; Bailey-Serres et al., 2012). Therefore, the concern of global food security in the era of climate change has compelled plant scientists in different crops to shift to breeding for climate resilient genotypes. Maize, being a hardy crop has an inherent potential to perform well under sub-optimal environments with minimum crop management (Kole et al., 2015). Abiotic stresses such as drought, heat and water logging affects maize yield adversely.

Although, conventional breeding approaches have exploited its fullest potential for production of elite maize hybrids but still little success attained for breeding climate resilient genotypes or varieties owing to the fact that stress tolerance is multi-genic or quantitative in nature. Therefore, the best option is to utilize the molecular breeding along with the conventional approaches for development of climate smart varieties.

9.1 INTRODUCTION

When a new individual arises from a somatic cell without formation of a seed, it is called vegetative propagation. Vegetative propagation occurs naturally (i.e., natural vegetative propagation) in many crops, and profitably exploited in horticulture using either conventional or biotechnological artificial techniques. We shall discuss conventional artificial vegetative propagation in this chapter including cuttings, grafting, budding, layering, suckering, etc. They have been widely used for commercial propagation of fruit trees and ornamental shrubs.

Introduction

Vegetables are preferable host to many insects because of their succulence and suitable nutritional status. All vegetables are attacked but degree of damage and number of pests varies depending upon the crop, variety and climate. Pest infestation in vegetables has been the main bottleneck in their economical production. The problem has more socio-economic dimensions because of rapid expansion of area under vegetables, intensive cultivation, round the year cultivation, export enhancement and health consciousness among the people.

The diamondback moth (DBM), Plutella xylostella (L.), is a major pest of brassica crops worldwide. DBM has been estimated globally to cost US$ 1 billion in direct losses and control costs. (Grzywacz et al., 2010)

Disease diagnosis refers to the various procedures and techniques used to identify the nature of disease and to precisely pinpoint the primary and secondary pathogens involved. Disease diagnosis is an integral part of health management. Proper diagnosis helps to adopt accurate therapy and avoids indiscriminate use of chemotherapeutics. Information on case history and clinical signs should be carefully used while examining samples for diagnosis. By following rational and scientific sampling protocols, one can hope to arrive at accurate diagnosis. Sampling methodology is key to the success of proper disease diagnosis. Dead fish/shrimp should never be used for any diagnostic purpose. Autolytic post-mortem changes, saprophytic invaders, spoilage organisms, etc. mask the actual etiological agents and can lead to false diagnosis.

The three commonly used conventional diagnostic approaches are fresh examination using microscope, microbiological methods and histopathology. With little facilities and infrastructure, fresh microscopical diagnostic approach can be done at the farm/hatchery site itself. Gross examinations along with simple skin and gill preparations examined under microscope can many a times give very good information about the disease and the etiology. All fresh preparations should be made from live or moribund fish and the preparations should be wet and moist. The fish meant for examination should be kept wet and not allowed to dry. Many of the commonly occurring external disease problems can be easily diagnosed by this method.

Systemic bacterial diseases need to be positively diagnosed by adopting the microbiological approach. Samples for bacterial isolations should be taken from kidney, blood, body cavity, etc. from live or moribund fish following strict aseptic conditions. In shrimp, it is ideal to use hemolymph for bacterial isolations. Dominant bacterial isolates are identified following standard procedures and their antibacterial sensitivity tested before recommending any antibacterial therapy. This method requires a minimum of 4-5 days.

There is no better engineering than life.

What is life - is a perennial question. Life is defined in different ways depending upon who is defining it. Biologists define life using a list of characteristics, such as metabolism, evolution, homeostasis, constant transformation, genetic information, etc. Life has been defined as self-maintaining and self-producing systems. Physicist Erwin Schrödinger (1), argued that living organisms escape the destiny of disordered equilibrium because they are able to take up ‘orderliness’ from their environment. Philosophers have defined life from different angles. They say that life can only be understood fully from an ‘insider’ perspective.

Life is not a random collection of extinct molecules. It is a process of dynamic renewal; everything in life is constantly turning over and renewed. Life exists in diverse forms. Each form is specialised to survive and reproduce in its particular niche.

One understands life from one’s own perspective. For some, life is an ‘objects in flux’ that constantly exchanges matter with the environment. It is systematic material exchange into an organized body. Then there is a view that says that all living organisms deserve moral consideration. All living organisms, however, do not have equal moral significance; vertebrates, for various reasons, deserve more moral consideration than would bacteria or plants. Then there are myriad religious ways to define life. The simplest is “God created the world and all living organisms.” No further questions, accept or reject the hypothesis.

Abstract

This chapter highlights the importance of re-engineering the functional processes prevalent in organizations today and realigning organizational resources with policies, procedures and systems that foster innovation in the technological and managerial space and institutionalize long term sustainability of businesses in emerging market economies such as India. These economies can serve as an engine for growth in a globalized era, if the intellectual capital of these economies is utilized and enhanced with maximum possible efficiency. It is in this scenario where entrepreneurial and decision making techniques based on the knowledge management-organizational learning continuum can help in the confluence of open innovation practices and stable management expertise. Such a comprehensive strategic shift from being a financial economy to a knowledge economy needs to be supported by integration of practical actions with the untapped cognitive potential of emerging economies. This chapter shall also be useful in explaining the importance of coexistence of competition and cooperation for enhancing the viability of the organizational ecosystem in the emergent Indian economy.

Organic farming necessitates a shift from conventional to non-chemical agricultural methods and practices. For this, it needs creation of facilities for the production of organic inputs, adoption of crop rotation, green manuring and other best management practices for the organic production of crops and livestock. Further, the ‘towards organic approach’ in intensive agricultural areas and ‘scientific organic farming’ in niche areas have to be implemented for development of an organic farm. The synthesized information on how to convert an inorganic farm into an organic farm followed by its sustainable maintenance is the need of the hour. This chapter holistically deals with designing and maintaing the whole ecosystem organic.

1. Introduction

Nowadays, the growers, policymakers and consumers are talking about organic farming (OF) across the globe. For practitioners, it is still a confusion regarding what and how to practice OF. There is a wrong notion that simple addition of organic manures and the use of chemical pesticides for growing different crops is considered as organic farming. In sense real, organic farms are the cultivated fields without addition of chemical fertilizers, pesticides, livestock additives, etc., and only organic and (or) non-chemical methods are practiced, and the concept or practice is known as organic farming. A large number of farms have been converted from conventional into chemical farms during the last more than 50 years by using synthetic chemicals. In view of the increasing demand for organic products and spiraling soil and human health problems, there is need to transform them gradually into organic farms. So that, it can help enhance soil organic carbon status and fertility which in turn can support crop growth and produce healthy foods besides protecting the environment. However, the extent of chemical used might be varying from one farm to another depending on the crops cultivated, nutrient requirement, pest/ disease severity, availability and accessibility to chemical use, socio-economic condition of the farmers, geographical location, etc.

The Metric System

At present metric system is followed to calculate final results in analysis work. This system is quite simple in nature as well as in principle. The units of the metric system are: (1) the  metre (linear measure), (2) the litre (measure of capacity), and (3) the gram (measure of mass.)

One litre is the volume of pure water at 4ºC and 760 mm pressure which weigh 1 kilogram (kg). One litre equals 1000.027 cubic centimetres (Cm3) for most work, the units “millilitre”, “cubic centimetre” and used interchangeably.

At present there are three different temperature scales in common use. These are: the Fahrenheit (F), used chiefly in English-speaking countries. the centigrade (C), used universally in scientific work and the Absolute (T) or Kelvin (K) scale, differing from the centigrade only in the position of the zero point, its divisions being of the same size. its zero point is -273ºC. The kelvin scale is used especially in dealing with very high or very low temperature and in computations involving the laws of gases. The following formulae can be used for converting one scale to another:

Conversion of muscle to meat is a complex process in which several physical and chemical changes takes place over a period of several hours or even days. The major changes which take place during this process include fall in muscle pH and temperature as well as muscle shortening which further leads to proteolysis or ageing. These changes during conversion of muscles to meat are variable and have great effect on meat quality (tenderness, juiciness, flavour, colour etc.) and also on certain processing characteristics like emulsification, binding properties and yield of the products. To know this complex process it is necessary to understand the process of energy production and metabolic pathway shifting in live animals.

Pre Slaughter

In the living animal, aerobic metabolism is used to obtain energy. The source of energy at this stage is either free fatty acids or blood glucose or muscle glycogen. In this process total 38 ATP molecules are produced from single glucose or glycogen molecule by the complex processes known as glycolysis, oxidative decarboxylation and oxidative phosphorylation. However, under stressful situations, anaerobic metabolism may be used and lactic acid is produced. Lactic acid is usually transported from the muscles to the liver, where it is re-synthesized into glucose and glycogen, or to the heart, where it is metabolized to carbon dioxide and water.

Effective application of pesticides depends on many factors. One of the more important is to correctly calculate the amount of material needed. Unless you have the correct amount of pesticide in your tank mix, even a correctly calibrated sprayer can apply the wrong rate.

Manufacturers provide application rate instructions on every pesticide label. Due to the variety of ways in which these recommendations are stated (such as lbs. of active ingredient (a.i.) per acre, lbs. of formulation per 100 gal. of spray, or ozs, of a.i. per 1,000 sq. ft.) it is often necessary to adapt the recommendations to different areas and volumes, or even other units. Sometimes the amount of active ingredient must be converted to the amount of actual product. This process can be very confusing.

9.1 Introduction

In order to increase the production and productivity of crops, provision of irrigation system is highly essential. A project that makes use of weir or a barrage for providing irrigation to fields is called as direct irrigation system. On the other hand, a storage irrigation system makes use of storage reservoir by construction of dams. In order to provide irrigation by both the schemes, it is necessary to have a network of canal systems. A canal is an artificial channel, generally trapezoidal in shape constructed on the ground to carry water to the fields. The canal systems that provide water to the fields include main canals, branch canals, distributaries, minors and watercourses. It is imperative to design the canal systems properly for a certain realistic value of peak discharge that must pass through them so as to provide sufficient irrigation to the command areas. The flow irrigation that provides irrigation water to the fields may be of two types i.e. Inundation irrigation and Perennial irrigation.

Principle

The use of boric acid as an ammonia absorbent was first introduced by winkle  (1913-15). Conway and O’Malley (1942) used boric acid for ammonia absorption in their original micro diffusion technique.

The ammonia liberated in the outer chamber by alkali addition in the usual way is absorbed in boric acid mixture plus indicator in the central chamber (slightly reddish), the pH of this mixture being approximately 5 before absorption. During the ammonia absorption the pH of the mixture rises, and to upwards of 8.0 (the strength of the mixture being such as to prevent it rising further). After the required period, the fluid in the central chamber is titrated to a faint permanent reddish tint with standard acid. A mixture of methyl red and bromocresol green was found satisfactory  to work as an indicator to assist in titration job.

ABSTRACT

The improper disposal of food waste poses an environmental threat. The management of food waste in a sustainable way is always a challenge. Food waste is generated at various stages starting from food production till consumption. The cooked food waste generated due to various reasons leads not only to a loss of the food produced but also the water and energy used to cook it. This cooked food leftover can be served to the needy people or if not possible, can be processed further. This chapter focuses on various technological options for the management of cooked food waste in a sustainable way.

Coordinate Reference System (CRS) is a framework of coordinate based local, regional or global reference system used to represent the locations of geographic features. Coordinate Reference Systems (CRS) provide a standardized way to define the real-world geographic locations which further enable us to use common locations of geographic datasets for integration. The datasets from different sources and CRS are transformed to a common CRS in order to perform various integrated analytical operations like overlaying of data layers. Coordinate Reference Systems are mainly of two types:

1. Geographic Coordinate System: This is global or spherical coordinate system in which locations of features on earth are defined in terms of latitude and longitude values. Latitude and longitude are angles based on a point at the centre of the earth. In this system, locations are defined by degrees, therefore, distances cannot be measured accurately. The most common geographic coordinate system is the World Geodetic System 84 (WGS84).
2. Projected Coordinate System: In this system, locations of features are defined using cartesian x, y coordinates on a flat, two – dimensional surface. This system is based on sphere or ellipsoid projected on flat surface. Projected Coordinate System are generally referred as projec- tion. It is required for preparing maps on paper or computer screen. Un- like Geographic Coordinate System, projected coordinate system has ac- curate measurements of distance, angles and areas across the two dimen- sions. However, there is alwaystrade-offs between area, direction, shape, and distance in this system due to distortions created while representing ellipsoid or spheroid on a flat map. So, the projection type is selected based on its application. Most common projections are Universal Trans- verse Mercator (UTM), Lambert Conformal Conic and Albers Equal Area.

In the semi-arid tropics, where small farmers depend heavily on rain-fed agricultural systems, variability in precipitation has a dramatic impact on crop production and livelihoods. Because small-scale agriculture depends on rain-fed cultivation, it is vulnerable to factors such as flooding and drought. Unfortunately, the frequency of unexpected heavy rainfall or flood events has increased in many areas of Africa, including Southern Zambia. About 75% of farmers in Zambia engage in small-scale farming, with an average farm size of 2 ha (VAM Steering Committee Zambia, 1998). Most of these farmers cultivate maize, which is a staple food in Zambia, and stable maize production and increased productivity are important both for food security and to provide a livelihood to farmers.

In spite of its importance, little has been done to assess interactions of climatic variability with productivity performance of different livestock species, sustainability of livestock production systems, livestock based livelihoods and application of science of climate change on small holder and subsistence livelihoods. The climate and its change affect all productive traits and physiological functions of farm livestock and related livelihoods. Heat stress is the most detrimental constraint to livestock production, particularly in mountainous regions. Introduction and selection for highly productive animals and breeds has increased their susceptibility to adverse impacts of climate change. It is necessary to incorporate resilience through selection and breeding for thermo-tolerance and development of adaptable breeds. Modifications in shelter designs and management of production facilities will also be helpful in mitigating adverse climate impacts on animal production and health. Modern animal husbandry practices that target increased per animal productivity allow efficient utilization of feed nutrients and increase returns from fewer animals. Livestock need to be looked for their immense contribution to nutritional security and livelihoods. A well designed livestock production system is among the best ways for sustaining and improving livelihoods and this chapter details the possible options.

Abstract

Intellectual property right (IPR) is the most serious, new branch of law and a legal right conferred by federal government in accordance with International conventions and treaties. IPR protects some of the finer manifestations of human achievement. IPR safeguards the application of ideas and information that are of commercial value. The exploitable ideas become more sophisticated and hope for a successful economic future depends increasingly upon the superior corpus of new knowledge and fashionable conceits.  Copyright law is one of the effective tools of IPR. Copyright law provides an incentive to creative activity of author and permits the society to benefit from those inventions. However, the technological advancement has made violation of copyright very easy and regulation very difficult. This paper aims at familiarizing  copyright laws and the powers enshrined in copyright laws.

I. INTRODUCTION

The Websites are soaked in information, much of it with varying degrees of copyright protection. In fact, the reality is that almost everything on the Net is protected by copyright law. E-business Websites are a composition of materials, often consisting of words, graphics, audio, and video that are expressed to the consumer as information content. The owners and Website developers carefully select the content to sell the company’s product or service. The subject matter expressed in the site is an electronic publication of this content. Since, designing, producing, and maintaining a sophisticated Website is very expensive, protecting content ownership is extremely important. Electronic commerce will continue to be highly competitive. As Websites become more and more interactive with consumers, their creation, design, and maintenance place enormous demands on innovative marketing techniques that should be legally protected.

Never before has it been so easy to violate a copyright owner’s exclusive right to copy the material. Everyone with a computer and an Internet connection creates his own Web pages and thus become a publisher. Hence the rules that once applied to only a few companies bind million of people now. Imagine having paid a Website developer hundreds of thousands of rupees to launch a killer application and acquiring millions of Rupees from a venture capitalist firm, only to discover that another e—business is using your online material. Or consider a scenario where your Website is linked to an e-business that displayed copyrighted material without the owner’s consent. Could your company be liable under a theory of copyright infringement? This paper highlights the scenario when contents of your Website are exploited by others without your permission or knowledge. The discussion is centered on copyright issues involved in the practices of linking, inlining and framing technologies which are normally being used on the Internet.

Copyright is a legal entitlement granted to creators of literary, dramatic, musical, and artistic works, as well as producers of cinematographic films and sound recordings. This legal right encompasses various privileges, including the reproduction, adaptation, translation, and communication to the public of the work. The composition of these rights may vary slightly, depending on the nature of the work. Along with Intellectual Property (IP), Copyright is a legal concept that safeguards the rights of creators and inventors. Copyright confers upon creators the exclusive legal right to reproduce, distribute, and exhibit their work, while IP comprises other legal rights such as patents, trademarks, and trade secrets. Copyright applies to a diverse range of creative works, including literary, dramatic, musical, and artistic works, as well as sound recordings and cinematographic films. Piracy is a worldwide issue that adversely affects various content industries, such as software, television, recording, and movies.

Copyright and IP laws play a crucial role in promoting creativity and innovation by safeguarding the rights of creators and inventors. These laws grant exclusive rights to creators and inventors, allowing them to financially benefit from their work. This encourages investment in research and development, leading to the creation of new ideas, products, and services. Without copyright and IP protection, creators and inventors may be discouraged from investing their time and resources into creating new works, resulting in a decline in innovation and economic growth. These laws also protect consumers by ensuring that they receive original, high-quality products and services instead of counterfeit or low-quality imitations.

Introduction

Corals, those captivating creatures of the underwater world, belong to the enchanting realm of Cnidaria—a diverse group of invertebrate animals. Among its mesmerizing members are jellyfish and sea anemones, which might have caught your eye in tide pools or along the shoreline. These creatures come in an astonishing array of hues, forms, and sizes, yet they all share a unique trait: a simple stomach sporting a solitary mouth encircled by tentacles armed with stinging cells.

Arid regions lie under the category of wastelands which are not being used to their fullest potential therefore, it almost barren. Hot arid regions are sparsely populated with human and animal population and experiences various biotic exploitation of the already very poor resources base. The scarcity of water poses biggest hindrance in limits the crop productivity as climatic factor. Yet, nature has bestowed the arid region fruits with characteristic qualities. Some fruit crops can grow successfully in such type of regions. Among these crops, cardia most suitable crop for cultivation under such type of arid climate. Some regional names of cordia are Pidar, Ponugeri, Maruvilli, Geduri, Spistan, Bhakar, Borla, Kalo Bohori (Nepali) etc. It is growing not only all over Asia but also nearly whole of the globe especially in tropical environment. In Indian sub-continent, it is growing from east Myanmar to west Afghanistan. It is grown in arid region and having numerous utilities. It is found in a variety of the forest of Rajasthan to moist deciduous forests of the Western Ghats and Tidal forest of Myanmar. In Maharashtra, it grows in moist monsoon forests also. In Rajasthan, its commercial plantations are being done in Pali, Sirohi, Udaipur, Jodhpur and Jalore districts.

Now, it is becoming popular as monoculture cultivation as well as under agroforestry system in arid region. It does not grow gregariously but is found growing singly in moist shady ravines and valleys. In areas with annual rainfall less than 500mm, it thrives along streams and depressions where moisture is available. The hot arid zone stretch 32 M ha or 0.32 million square kilometer long covering Rajasthan (62%), Gujrat (20%), Andra Pradesh (7%), Punjab (5%), Haryana (4%), Karnataka (3%) and Maharastra (0.4%). In these area fruits selection for cultivation must be cope up that their maximal growth period coincides with the period of water availability in the soil. Few of the xerophytes characteristics are: deeper root system, deciduous nature, reduced foliage, sunken of covered stomata, waxy coating or hairiness on leaf surface which minimize the evapotranspiration and makes plant adaptive to the hostile climate. These qualities are found in cordia plant which can grow in this area without any problem after management of some agro-techniques.

“Small is beautiful”, today we know that small is not only beautiful but also powerful. With the range of applications that nanoparticles find in varied fields of engineering and science, nanoparticles seem a promising option when compared to the conventional materials used. Nanoparticles are particles that have at least one dimension in less than 100nm range. They have a high surface to volume ratio and thus mass transfer and heat transfer properties are better than bulk materials. Recently; core/shell nanoparticles are finding widespread application. There is a class of core/shell nanoparticle that has its entire constituent in the nanometer range. Core/shell nanoparticles are nanostructures that have core made of a material coated with another material. They are in the size range of 20nm-200nm. Also, composite structures with these core/shell particles embedded in a matrix material are in use. The necessity to shift to core/shell nanoparticles is the improvement in the properties. Taking into consideration the size of the nanoparticles, the shell material can be chosen such that the agglomeration of particle can be prevented. This implies that the monodispersity of the particles can be improved. The core/shell structure enhances the thermal and chemical stability of the nanoparticles, improves solubility, makes them less cytotoxic and allows conjugation of other molecules to these particles. The shell can also prevent the oxidation of the core material. “When a core nanoparticle is coated with a polymeric layer or an inorganic layer like silicabecausethe polymeric orinorganiclayerwould endow the hybrid structure with an additional function/property on top of the function/property of the core hence synergistically emerged functions can be envisioned”.
