Introduction

Society is dynamic. The requirement of society varies in course of time. During the life process human being faces lots of health hazards which are mostly due to intake of various foods. So people become cautious about the intake of food and think about the quality of foods which can protect the health of human being. In ancient times people made medicines from plant extracts to protect their health. In 1989, Dr. Stephen coined the term “Nutraceuticals” which is combination of nutrition and pharmaceutical. Nutrition is required for health and pharmaceuticals provide remedy for sickness. So it is a preventive approach. Nowadays, the definition of nutraceuticals has been expanded to include vitamins, minerals, herbs and other botanicals, amino acids, and dietary substance for human use as a supplement diet (Stauffer, 1999).

Nutraceuticals are dietary supplements made only from whole foods to augment health. Currently over 470 nutraceutical and functional food products are available with documented health benefits (Brower, 1999). The patients are much aware about the side effects of chemical agents in short and long term therapy. So to avoid medicine used for small diseases, new therapies came into trend with the help of nutritional approaches i.e. “Nutraceuticals”. The use of nutraceuticals becomes easier than pharmaceuticals since nutraceuticals does not require any animal verification for its use in human. Nutraceuticals,

Functional foods and Dietary Supplements are most important concept in food science. They have distinction amongst themselves.

Introduction

Our traditional knowledge of medicine has been one of the strongest areas of research because of our rich heritage in herbal plants & great biodiversity in our fauna & flora. Consumption of plant foods and the structurally diverse natural products provided by them have long been associated with health-protective and therapeutic effects. Natural products in plant foods have been shown to have pleiotropic therapeutic and chemopreventive properties. These bioactive products are known to potentiate the efficacy of other drugs and have synergistic effects too. Most of the prescription drugs discovered so far is from plant sources and 75% drugs had been claimed in folklore claims and traditional medicinal system (Reynold, 1991; Benowitz, 1996). The traditional Indian medicinal system utilizes multicomponent formulations of plant extracts which may either act synergistically or avoid many side effects and might have added up trace element through combination of different plant extracts which could have additive effects. However the effort to utilize traditional knowledge in the light of modern scientific findings is lacking in India. Accumulating evidences as well as in-vitro studies implicates inverse relationship between regular consumption of fruits vegetable and the risk of specific cancer. Diet derived nutritional compound mediated interventions in the process of tumorigenesis may be promising chemopreventive strategy with minimal toxicities to the physiological system.

Introduction

During the first 50 years of the 20th century, scientific focus was on the identification of essential elements and their role in the prevention of various dietary deficiency diseases. This emphasis on nutrient deficiencies or “undernutrition” shifted dramatically, however, during the 1970s when diseases linked to excess and “overnutrition” became a major public health concern. “Let food be thy medicine and medicine be thy food”, the age old quote by Hippocrates is the ideology of today’s health conscious population. Eli Metchnikoff, the Russian Nobel prize winner was the first one to recognize the beneficial role of selected bacteria on gastrointestinal tract of humans. Subsequently the “Theory of Longevity” by Metchnikoff was correlated with prolonged youth and a healthy old age, observed largely in Balkan peasants of those times, who used cultured milks in their diet (Kaufmann, 2008). Since then, the quest continues for understanding the role of wide range of food components and nutrients in enhancing health or preventing chronic diseases. The research in this field has resulted in a plethora of new labels for pro-, pre- and synbiotics.

ABSTRACT

With the advancement of mobile technology, the usage of mobile application has increased significantly which leads to change the life style of common people. Library is also not an exception in this context. Library and Information Science Professionals have started to incorporate the changes from the beginning of ICT advancement with an idea “library should be within thumb of people”. Mobile application plays vital role to fulfil the objective of library. Most of the library has started or planning to start the service to its user with various services effectively. But, the process to provide library service through mobile application is not satisfactory till date. No too much usage of libraries mobile apps can be seen; even which mobile applications are in use, most of them are almost inactive form.

But the various recent surveys show us the tremendous growth of the usage of mobile application among people. According to Google, (2017) the user survey shows that mobile can fast-track time to purchase by 20% through facilitating efficiencies in decision-making and enhanced team collaboration, particularly with more complex purchases.

ABSTRACT

The chapter focuses that information as an economic resources and the role of library to distributing information among the user’s communities. From the economic point of view-the most important properties of information are easy to access and limited money acquire more information i.e. cost benefit. Information economy makes people ware about their goal and library help people to provide resources on need base.

ABSTRACT

Academic libraries are unique, essential and strategic hubs inside our social cloth which are advanced primarily based totally at the requirements of the times, to help people in the purchase of good enough facts that could allow them to decorate their information, for the development in their wellness and that of the society at large. To attain their goal, they ought to generate, filter, control and diffuse correct and well timed human information which have been harvested and documented; for the purpose of enriching the highbrow needs in their clients. Like every other kind of library, academic libraries are growing organisms. Justification to the above statement has been captured aptly in the classic book of Ranganathan (1931) entitled ‘Five Laws of Library Science’; detailing the principles of the library profession. The philosophical postulation of Ranganathan’s fifth law is a classical position that offers much strength and support for the need to adequately plan for the best strategies to exhibit in academic library environments in order to provide effective services. In other words, the fore-stated law by Ranganathan has already signaled that academic librarians must be ready at all times to effectively satisfy the diverse, complex and ever-increasing information needs of their users from the explosive available information resources that spring on a daily basis. As such, addressing this issue would require a holistic management approach by academic libraries that must be internally efficient and externally effective.

ABSTRACT

It is very important for every library to have all the resources/materials necessary to fulfil its target. The working of a library can be classified into two forms: dealing with the users and behind the scene. There are numerous different sections in a library divided on the basis of their functions. Most important of these is the Acquisition section. A library’s success lies in a well organized acquisition section. Main aim of the library is the contentment of the users. However, collection development is the primary task of the acquisition section which further contributes to user satisfaction itself. It performs the process of selection, procurement and accessioning of reading materials as well as maintains records. It organizes the monetary as well as human resources in such a manner that collection is facilitated more and that too in an economic and less time consuming way. All this is the responsibility of the librarian. Before acquiring the reading materials, the librarian is supposed to decide that which items are actually required in the library and which are to be rejected. A librarian must study the requirements of the library and acquire materials as per the priorities of the institution to achieve its goal.

4.1 Introduction

Banana (Musa spp.) is one of the oldest fruits and second largest growing fruit crop in the world. It is also known as Adam’s Fig and Apple of Paradise. Important banana growing states are Maharashtra, Karnataka, Kerala, Tamil Nadu, Andhra Pradesh, Odisha, Bihar, West Bengal and Assam. In South India, banana is extensively used in all auspicious occasions such as wedding, festival and worship. Banana is a good table fruit. The cultivar Nendran is used for cooking; it is also used for preparation of halwa, sweet, chips etc. Main bud or heart of banana bunches is also used as vegetable in India, Thailand, Philippines, Malaysia and Indonesia. Musa textiles is known for strong fibre quality. Ripe banana contains about 20% sugar (but no starch) and about 4.7% protein. Further, it contains vitamins A, B, C, D and E and minerals such as K, P, Ca and Fe.

5.1 Introduction

Citrus is one of the most important fruit crops in the world. It is grown in the tropical and sub-tropical regions of the world. The top ten citrus producing countries are China, India, Nigeria, Brazil, Mexico, USA, Spain, Egypt, Italy and Argentina. The citrus industry in India is the third fruit industry after mango and banana. The important groups of crops in citrus are sweet orange, mandarins, limes, lemons, grape fruits and pummelo. The most important commercial Citrus species grown in India are mandarin (Citrus reticulata Blanco.), followed by sweet orange (Citrus sinensis (L.) Osbeck) and acid lime (Citrus aurantifolia Swingle). The major citrus producing states are Maharashtra, Karnataka, Andhra Pradesh and Punjab.

7.1 Introduction

Papaya is a fruit crop grown in kitchen garden, backyards of home and orchards. It is grown as a filler crop in orchard. India is the largest producer of papaya in the world. It is also cultivated in Brazil, Mexico, Australia, Hawaii, Malaysia, Taiwan, Peru, Florida, Gold Coast, South Africa and Bangladesh. In India, it is widely cultivated in Uttar Pradesh, Bihar, Karnataka, Jharkhand and Madhya Pradesh. The ripe fruits of papaya are consumed throughout the tropics and sub-tropics. Fruits are also used in the preparation of jam, soft drinks, ice cream flavour, crystallized fruits and syrups. Unripe fruits are commonly used as vegetables. Papain is prepared from the latex of immature fruits. It is a proteolytic enzyme used for tendering of meat, preparation of chewing gum and cosmetics. The ripe fresh fruit is rich source of vitamin A, carbohydrates and minerals. The fruits are prescribed for piles, dyspepsia, liver, spleen and digestive disorders. Roots are used as nerve tonic. The plants flower five months after planting and fruits are ready five months after flowering. So, it has attracted attention of fruit growers to cultivate on a large scale in the country.

8.1 Introduction

Guava is the fourth important fruit crop next to mango, banana and citrus. It is known as the ‘Apple of tropics’. It is very rich and cheap source of Vitamin C and also contains a fair amount of calcium. Important guava growing states are Uttar Pradesh, Bihar, Madhya Pradesh and Maharashtra. Allahabad district of Uttar Pradesh has the reputation of growing the best quality of guava fruits in the world. The importance of guava is due to the fact that it is the hardy fruit which can be grown in alkaline and poorly drained soil. Guava fruits are used for making jam, jelly and various culinary purposes. The fruit can be canned in sugar syrup.

Any commercial plant breeding programme run by the private seed companies typically called as Research and Development (R & D) is carried out through various models operating. There is no fixed organizational set up and different companies adopt the working set up as per size of their programme, availability of manpower and resources, area of the breeding station and several other considerations. One thing is clear that any commercial plant breeding programme will have more numbers of crop breeders than the supporting scientists.

A significant development in the field of agricultural research in India is the formulation of All India Coordinated Research Projects (AICRPs), initially for the improvement of agricultural crops, but later extended to all aspects of crop husbandry.

3.1. Types of communication network

There are different situations in which different kind of communication is required for transfer of technology. An Extension expert works in an organization.

4.1 The non-verbal communication

The non-verbal communication is the use of human body as the medium of message. The non-verbal communication forms a vital part of the process of communication that an individual goes through daily.

A pH meter is very commonly used for the measurement of the reaction of a solution or a medium. The pH determination with the help of a pH meter is based on the measurement of the electromotive force (e.m.f) of a pH cell consisting of an electrode sensitive to W ions and a reference electrode.

The term biodiversity is used by Walter and Roses in 1985. Biodiversity means the existence of a large number of different kinds of animals and plants which make a balanced environment. According to “Convocation on biological diversity (1992)”-Biodiversity is present in terrestrial, ocean and aquatic ecosystem. This diversity present in between same species, different species and in different ecosystem.

Ultrasonographic examination of gastrointestinal tract is not very much rewarding in dogs because of gas in the tract but it is crucial for a correct diagnosis. Imaging of stomach plays a significant role in the diagnosis of gastric diseases such as gastric dilatation, gastric foreign bodies, pyloric outflow obstruction, or gastric tumours.

Ultrasound and survey radiography are two important diagnostic modalities regularly employed in the diagnosis of intestinal diseases. Both modalities are complementary to each other in investigating the problems related to intestines. It is always better to have plain survey radiograph of abdomen first and then ultrasound to rule out obstruction or radio-opaque foreign bodies. Wherever barium meal radiograph is indicated, it should be done after sonographic examination as barium may degrade image quality of the sonogram. Assessment of intestinal motility can be done in real time sonography.

Architecture of the organ is affected in the primary or secondary diseases of the organs. Ultrasonography plays a significant role in detecting the changes in the organs in various diseases.

During last two decades significant advances have been made in diagnostic ultrasound .These advances have positively impacted on diagnostic imaging across all species of animals and have made ultrasound as an indispensable diagnostic modality in veterinary medicine. Since equines have been more a sport and pack animals, the ultrasound technique has long been utilized in the diagnosis of equine musculo-skeletal disorders. Recent years have witnessed its utility in the management of equine reproduction beside its use in the diagnosis of colic and other diseases.

Biometrical genetics: This is a branches of genetics which uses the statistical concept and procedures for the study of genetic principles.

There are various methods available for isolation of high molecular weight genomic DNA from plants. The basic steps involved in all these methods are removal of cell wall, nuclear membrane, proteins, lipids, carbohydrates, cell debris, RNA without affecting the integrity of DNA. The two major factors that affect DNA integrity are action of endogenous nucleases and impact of mechanical shearing.

Polysomes consist of two or more ribosome traversing a strand of mRNA, translating the nucleotide sequence into the corresponding amino acid sequence. Usually at any time, many ribosomes are translating an mRNA simultaneously forming a structure called a polyribosome or polysomes. One reason for isolating polyribosomes is to resolve them on sucrose gradients to determine the extent of ribosome loading. The second main reason is to provide a source of mRNA for in vitro translation.

Exchange of genetic material rarely occurs between unreleated organisms and even similar species may not exchange chromosomal genes. A certain degree of DNA sequence homology is a prerequisite for genetic recombination in vivo. However, recombination between DNA molecules in vitro is not subject to such taxonomic restrictions.

Recombinant DNA is advancement in molecular technology which allows manipulation of genomes of higher organisms and dissection of their complex regulatory circuits. This new methodology is being used to understand the biochemistry of living organisms. The isolation of gene begins with the cloning of fragmented DNA of the organism into appropriate vector. 

M13 is a single stranded filamentous DNA phage. Vectors have been developed from M13 phase by Joachim Messing (1983), which are suitable for preparation of single stranded DNA required for sequencing by Sanger’s method. These are derivatives of M13 wild type (size 6.407 kb).

This research seeks to address some major concerns of communication through cyberspace and its socio-cultural implications. In particular, it seeks to address the use of cyberspace or Internet as a potential medium of communication for the people of Odisha and the relatively positive and negative outcomes of the use of this medium. It investigates the current Internet-mediated communication practice in the twin city (Bhubaneswar and Cuttack) of Odisha and explores the social and cultural implications of the new communication mode.

Introduction

In the last two decades, there has been a significant change in the Indian society, not only in the terms of economics following the post 1991 reforms but also in the dietary and health sectors. There is an increasing demand for livestock products, as a result the farming systems are becoming more and more intensive. With the high input intensive agricultural practices on the one hand, the limitations in terms of environmental degradation, loss of biodiversity, health hazards to consumers, etc. are also on the rise which are acting as limiting factors to continue on the same path of intensification. To achieve sustainable intensification of agriculture, mixed crop-livestock systems, combining livestock and cash crops at farm level, are considered to be a good alternative (Russelle et al, 2007; Wilkins, 2008; Ryschawy et al., 2012). These practices benefit the environment by improving nutrient cycling (Hendrickson et al., 2008). In the agriculture based states of India, about 50% of the income is from the crop-livestock systems (Deshingkar et al., 2008). Mixed crop-livestock systems also generate higher economic efficiency in saving production costs through complementaries between crop and livestock (Wilkins, 2008). Apart from direct income by diversifying production, there is an added advantage of reducing risks with regard to market fluctuations (Russelle et al., 2007).

Introduction

Advancement in agricultural research has increased productivity however, in recent years, poor linkage of research - extension services hampering the growth of agriculture sector. Firstly, the research problems are investigated without considering the priority of agricultural producers Secondly, knowledge generated at the agriculture research stations is not effectively transferred to the producers. Many studies have identified the weaknesses in the linkages between the research and extension institutions are the major reason for development of technology and its transfer. In most countries including our country, the communication between research and extension agencies is weak (USAID 1982, FAO 1984). Research-extension-farmer linkages are seen to be absent or weak in many instances. At the same time, there are duplications of efforts, with a multiplicity of agents attending to extension work without adequate coordination (Planning Commission, 2008). This ineffective linkage between research and extension has impeded the generation and transfer of technology appropriate for small-scale and resource poor farmers, particularly those who work in relatively low productive and heterogeneous agro-ecological areas (Ewell 1989). Problems in technology generation and transfer arise because these components are considered in isolation (World Bank 1985).

Introduction

The modern biotechnologies (animal cloning, stem cells, and transgenesis) have contributed immensely to increasing livestock productivity, particularly in developed countries, and could help to alleviate poverty and hunger, reduce the threats of diseases and ensure environmental sustainability in developing countries. A wide range of biotechnologies are available and have already been used in developing countries in the animal science disciplines, i.e., animal reproduction, genetics and breeding; animal nutrition and production; and animal health. In animal reproduction, genetics and breeding, artificial insemination (AI) has perhaps been the most widely applied animal biotechnology, particularly in combination with cryopreservation, allowing significant genetic improvement for productivity as well as the global dissemination of selected male germplasm. Complementary technologies such as monitoring reproductive hormones, oestrus synchronization and semen sexing can improve the efficiency of AI. Embryo transfer provides the same opportunities for females, albeit on a much smaller scale and at a much greater price. Biotechnologies in animal health are used to increase the precision of disease diagnosis as well as for disease control and treatment. The Biotechnology Industry Organization claims that the genetic engineering of animals in agriculture offers ''tremendous benefit to the animal by enhancing health, well-being and animal welfare'' (Gottlieb and Wheeler 2008). Further, improvements are still needed in product composition and production efficiency, especially in growth, disease resistance, and reproduction. In this regard, transgenic animals stem cells, cloning and other emerging biotechnologies will have important roles in producing more and higher quality animal food.

Introduction

During the last decade, there has been a dramatic increase in use of artificial insemination (AI) by commercial swine producers in many European countries. Till 1990, less than 7% of sows & gilt in the USA were bred by Artificial Insemination. Today, over 70% of the animals are bred by AI. Maybe in a couple of years all swine producers will probably utilize this technology.

In India, it is still in infant stage. Some research work has already been done in scattered ways in various Research Institutes but it is still in the four walls of the laboratory. Some Govt. farms have been doing AI in swine with liquid semen.

Pig is the most important livestock in all Northeastern Hill States and there is no superior indigenous germplasm available in this region. Productivity of local pigs is very low. All through, improvement programmes had undertaken in different state Govt. farms, Central Govt. farms through upgrading with the help of suitable exotic pig breeds like Hampshire, Large Black, and Large White Yorkshire etc. Superior germplasm was distributed to farmers for better productivity. But, improvement till date is not impressive due to lack of superior germless, high feed cost, lack of breeder farmers and lack of incentives to the poor farmers. Maintenance of breeding boar for small farmers is very expensive not only in individual capacity but also on community basis. So, AI is the only tool for quicker, safer, quicker and economic why out for swine improvement like cattle.

Introduction

The science of Biotechnology has been making every effort to create new opportunities for the welfare of humanity. Modern biotechnological tools are applied in India to boost fish production through aquaculture as well as conservation of the vast aquatic resources of the country for sustainable utilization. Transgenic technology is widely used in biotechnology, from the generation of genetically modified (GM) foods to the production of pharmaceutical proteins. This technology has been successfully used to develop fast growing super-fish stocks for aquaculture. The main reasons for genetic manipulation of species used in aquaculture are to enhance the growth and efficiency of food conservation, to increase tolerance to environmental variables like temperature and salinity, to produce new colour variants of ornamental fishes, to increase the resistance of species to pathogens, etc. Though the conventional selective breeding approach has proven to genetically upgrade rohu19, it is a rather time consuming process. Traditional selective breeding approaches in combination with transgenesis can bring about faster improvement of selected traits.

Introduction

Genetic programs in livestock have been extensively used to improve their productivity over the last 50 years. The traditional approach of breeding, based on quantitative genetics principle, has been very successful (Schaeffer, 2006), without knowledge of genes increasing or decreasing in herds. Effective progeny testing program and use of genetically proven bulls have made drastic genetic improvement in livestock populations. Further advances in computation for genetic merit have further added to improvement process. Livestock producers presently are focusing on overall development of livestock with improved health, production, reproduction and longevity and therefore, the traits are becoming the part of selection program (Decker et al., 2009). Advancement in molecular biology along with high-throughput genotyping has led to discovery of a number of single nucleotide polymorphisms (SNPs) in livestock (Van Tassell et al., 2008). SNP arrays covering the entire genome may explain most of the genetic variation in important traits of livestock (Meuwissen et al., 2001). These SNPs may act as molecular markers and be used as a substitute for phenotypic selection. This process, in a broad sense is known as molecular or marker-assisted breeding and describes selection strategies including marker-assisted selection (MAS) and genome wide selection (GWS) or genomic selection (GS).

Introduction

In developing countries, ruminants thrive mainly on poor quality feeds and pastures, whose nutritive value is poor. They are having a low content of nitrogen, energy, minerals and vitamins and high content of lignin and silica, which limit their efficient utilization by ruminants. Therefore, these poor quality feeds and fodder needs to be upgraded in terms of their nutritive value using various treatments like physical, chemical, physico chemical and biological methods to improve intake and utilization of nutrients from poor quality roughages. However, supplementation of critical nutrients like energy, protein, minerals, vitamins also improved the productivity and health of the ruminants (Dass et al., 2011). Availability of oil cakes as protein supplement in developing countries is very poor and at a very high price, This has led to use of non-protein nitrogen source as urea, to compensate for the nitrogen deficiency of fibrous feeds (Dutta et al., 2009). Thus, enhancing intake, digestibility and availability of nutrients from poor quality roughages are only possible through optimization of rumen fermentation. The use of solid multi-nutrient block supplementation /urea-molasses blocks/ multi nutrients blocks/ pashu chocolates to provide optimum levels of various nutrients primarily for better growth of rumen micro organisms. They need rich sources of fermentable nitrogen, minerals and vitamins, which are lacking in the fibrous feeds like cereal straws (Sahoo et al, 2009). This offer several advantages such as easy transport, storage and handling, and reduced risks of poisoning as compared with other approaches, such as giving a small amount of urea in drinking water, sprinkling of urea solution on fibrous feeds before feeding, or urea-ammonization of crop residues (Dutta et al ., 2009).

Introduction

Incidence of ectoparasitism is on rise in the livestock population, impeding its production and performance. Those areas which were free of ectoparasites are now under great parasite load because of changing climatic conditions and global warming. Global warming has resulted in vectors shifting their habitats to temperate regions also. Ectoparasites are not only causing irritation to livestock by blood sucking and associated pruritus, they are serving as vectors for a variety of haemoprotozoan and rickettsiae leading to far-flung complications. Major ectoparasites infesting ruminants are ticks, lice, fleas and flies. Though ticks and flies are proclaimed as notorious for transmission of haemoprotozoans, now a days evidences are on rise reporting the role of fleas and lice as vectors for various haemoprotozoan and viral diseases. The need of the hour is to explore more and more ectoparasites to identify their vector potential and their effective control measures. While addressing the ectoparasitism in livestock, another major problem arises with their control. Most ectoparasitism is of seasonal nature at least in temperate areas, while it is a round the year phenomenon in tropics. Only very few compounds are available as ectoparasiticides and used by clinicians, and has resulted in onset of resistance among ectoparasites. New compounds need to be developed and marketed to counter this and at the same time it should be environment friendly also. Lest their rising use can lead to eradication of friendly fauna which can be more detrimental to the ecosystem. Now a days researches are focusing on the development of integrated tick/vector control measures which are making use of minimal chemical compounds and utilizing the synergistic application of farming techniques/practices and cultivating plants of acaricidal properties. In this era of pandemic, zoonotic nature of various haemoprotozoan/rickettsiae affecting livestock is also of concern to the mankind. So, they need to be addressed at the earliest considering their impact. The susceptibility to ectoparasitism varies from animal to animal.

1.1 Introduction

Python is an interpreter, high level, general purpose programming language developed by Guido Van Rossum and its first version was released in 1991. There are two major Python versions: Python 2 and Python 3. Both are quite different.

1.2 Beginning with Python Programming

1.2.1 Finding an Interpreter

Before we start Python programming, we need to have an interpreter to interpret and run our programs.

Windows: There are many interpreters available freely to run Python scripts like IDLE (Integrated Development Environment) that comes bundled with the Python software downloaded from http://python.org/.

Linux: Python comes preinstalled with popular Linux distros such as Ubuntu and Fedora. To check which version of Python you’re running, type “python” in the terminal emulator. The interpreter should start and print the version number.

macOS: Generally, Python 2.7 comes bundled with macOS. You’ll have to manually install Python 3 from http://python.org/.

4.1 Introduction to Function in Python

Python Functions is a block of related statements designed to perform a computational, logical, or evaluative task. The idea is to put some commonly or repeatedly done tasks together and make a function so that instead of writing the same code again and again for different inputs, we can do the function calls to reuse code contained in it over and over again. Functions can be both built-in or user-defined.

Function means sub-program

1. Function definition

2. Function call

Example:

def message: #function definition

print(?hello python”)

message() #function call
