19.1 Introduction

Coconut is valued most for its nut. The other components are coconut water, kernel, shell and husk. Coconut water is one of the most refreshing drinks. It is also known for its medicinal value. It increases blood circulation in kidneys, causes profuse diuresis and eliminates mineral poisoning. It is a good substitute for saline glucose under gastroenteritis conditions. The coconut has been regarded as ‘Kalpavriksha’ because all the parts of the palm is useful to mankind in one way or other. The dried kernels commonly called as copra is the richest source of vegetable fat (60-67 % oil). Coconut is major source of edible oil. India is the largest producer of coir and its product. The major coconut growing areas of the world are found in Asia, Oceania, West Indies, Central South America, East and West Africa. In India, coconut is commercially grown in Kerala, Karnataka, Tamil Nadu, Andhra Pradesh, Gujarat, Odisha and West Bengal.

ABSTRACT

With the rapid innovation in Information and Communication Technologies (ICTs), the libraries and information centres have gone through tremendous changes or facing transformation. In this digital era, libraries are facing heavy technological pressure to serve their users on their satisfaction level. Library and information professionals are also struggling more to implement these cutting-edge technologies for learning, research, and information for their users. Therefore, the library and information centres have now been trying to adopt and implementing various emerging or cutting-edge technologies in housekeeping activities as well as in its services. In this paper, an effort has been made to evaluate some of the cutting-edge technologies in libraries’ point of view. An overview is also made to evaluate the concept, advantages and disadvantages of cutting-edge technologies.

1. Introduction

Dave Cormier devised the term Massive Open Online Course (MOOC) in 2008 to describe an open online course “Connectivism and Connective Knowledge” designed by Siemens and Downes. University of Manitoba offered MOOC for the first time in 2008 formally as a credit course to regular students and informally with enrolment open to anybody in the world free of cost. Since then, there is proliferation of MOOCs worldwide.

ABSTRACT

There is a tremendous growth in the open educational resources in the recent past and large number of universities and academic organisations are making their resources freely available over the internet which has become a significant source of open educational content. Open education movement are built on the belief that anyone can use, access, reuse and redistribute these educational resources without any constraints. These Open education movements are helping educational community worldwide in making education more accessible and in making it more effective. In this chapter effort has been made to provide an overview of the history and emergence of open educational resources’ movement. This chapter also explains the various characteristics and sources of open educational resources. This chapter will help the libraries and librarians to know about open educational resources initiatives and to incorporate them in their libraries for effective resource delivery and disseminations.

ABSTRACT

The hearing impaired Persons constitute a very small percentage of the total population. The article presents the information regarding the infrastructure, the library services to the special group of library users. All the public/academic libraries do not provide services to these groups of the users, hence the institutions specially meant for these persons are responsible for administering services to this group of users. Assistive technology can help to a great extent in providing library services to these groups of users.

Keywords: Physically challenged persons, Hearing impaired library users, Library infrastructure, Library services, Information Technology, Assistive devices.

1.1 Agricultural technologies and knowledge

Agricultural technologies and knowledge have, until recently, largely been created and disseminated by public institutions. But over the past two decades, biotechnology for agricultural production has developed rapidly, and the world economy has become more globalised and liberalised

a) Ethology b) Epidemiology

c) Ecology d) Etiology

Sustainable Development A social cause is a problem that influences a considerable number of individuals within a society. There are many environmental issues the India like pollution, waste management sustainable development, rain water harvesting etc.

A. Define/Explain the following

1. Heteroploidy: Any change in chromosome number from the diploid state.

2. Euploidy: Numerical change in the entire genome.

Plasmid is a double stranded, self replicating, circular extra chromosomal DNA of bacterium. It is used in recombinant DNA experiments to clone genes from other organisms and make large quantities of their DNA. Plasmid can be transferred between same species or between different species. The sizes of plasmids range from 1-1000 kbps. Plasmids are part of mobilomes (total of all mobile genetic elements in a genome) like transposons or prophages and are associated with conjugation.

RNA is transcriptional product of DNA. The total RNA includes three classes, rRNA, tRNA and mRNA. The ribonucleic acids exists as ribonucleo protein particles in intact cells. The ribonucleo protein complex is dissociated by SDS in to RNA and protein deproutinised by phenol and the free RNA left in the aqueous solution is precipitated in cold by adding alcohol. 

Nucleic acid hybridization requires denaturation i.e. the breakage of H-bridges between the complementary strands of the DNA either by heating at high temperatures or by treatment with denaturing chemicals like formamide. The restricted DNA, therefore, is denatured before transfer from the gel onto synthetic membrane since only single stranded DNA binds to nitrocellulose.

DNA can be sequenced in both double stranded and single stranded templates by cloning in plasmid or phage vectors. There are two sequencing methods.

Protoplasts are cells which have had their cell wall removed, usually by digestion with enzymes. Cellulase enzymes digest the cellulose in plant cell walls while pectinase enzymes break down the pectin holding cells together. Once the cell wall has been removed the resulting protoplast is spherical in shape. Digestion is usually carried out after incubation in an osmoticum (a solution of higher concentration than the cell contents which causes the cells to plasmolyse). This makes the cell walls easier to digest. Debris is filtered and/or centrifuged out of the suspension and the protoplasts are then centrifuged to form a pellet. On resuspension the protoplasts can be cultured on media which induce cell division and differentiation.

Developments in recombinant DNA technology have made it possible to transfer gene from any source across species barrier. In fact, transfer and expression of foreign genes in plant cells is now a routine procedure. Of the several methods tried so far, the system based on Ti plasmid of Aprobacterium tumefaciens appears to be most successful for transformation of plant cells.

This chapter outlines the design of Phase One and Phase Two of the research. It outlines the research approaches and methodology utilized in Phase One and Phase Two of the research. The chapter also provides details of the sampling strategies, data sources, collection and analysis of both the phases; and finally addresses ethical issues.

In the detection of soil organic carbon a known weight of soil is heated with an excess volume of standard K2 Cr2 O7 in the presence of Con. H2 SO4 . The soil is slowly digested at the low temperature by the heat of dilution of H2 SO4 and the organic carbon in the soil is thus oxidized to CO2 . The highest temperature attained by the heat of dilution reaction produced with the addition of Con. H2 SO4 is approximately 12o C which is sufficient to oxidize the active forms of the soil organic carbon but not the more inert forms of carbon that may be present.

Dactylis glomerata L (syn. Bromus glomeratus (L.) Scop. (Poaceae): Eng.- Orchard Grass; Kash.- Dramun [W]. Perennial bunch grass,usually in dense shaded forest areas. A very important pasture and hay grass of temperate grasslands. Culms glabrous, erect. Inflorescences are erect panicles bearing spikelets in dense one sided clusters.

Echeveria derenbergii DC (Crussulaceae): Eng.- Painted Lady [NI]. A succulent house plant and green house perennial grown for its succulent coloured leaves which are arranged in rosettes. The orange coloured flowers appear in July on raised stem branches

Halerpestes tricuspis (Maxim.) Hand maz. (Ranunculaceae): LadakhiChitaka [W] Annual herb of alpine zone of above 3500 m altitudes. Whole plant used as stomachic and for gastrointestinal problems.

Vaccaria hispanica (Mill.) Rauschert. (Syn. Saponaria vaccaria L.) (Caryophyllaceae): Eng.- Cow Soapwort/ Cow Basil [W]. Annual herb,as weed of orchards.Plant has blue-grey, waxy herbage and pale pink flowers. Used traditionally to relieve body swellings.

The Horticultural crops are majorly classified on the basis of its consumption and uses as fruits, vegetables, flowers, spices, medicinal, aromatic and plantation crops. Moreover, these crops have been further classified into various groups on the basis of their habitat, growth pattern, edapho-climatic requirements and uses

A seed (in some plants, referred to as a kernel) is a small embryonic plant enclosed in a covering called the seed coat, usually with some stored food. It is the product of the ripened ovule of gymnosperm and angiosperm plants which occurs after fertilization and some growth within the mother plant. 

Irrigation is one facet of the inputs which need to be carefully managed so that profits are maximized. Irrigation plays a major role in any agriculture crop production. One should be aware of different types of irrigation adapted in orchards or crop cultivation to become a successful grower. Irrigation is very important component of crop cultivation as sufficient moisture must be maintained in the soil for obtaining the optimum growth and good quality yield. The aim of irrigating a plant should be to wet the entire root zone without allowing any wastage of water beyond the root zone.

Q.1 Systematic random sampling or systematic sampling, both are different sampling schemes.

Q.2 The pattern usually followed in selecting a systematic sample is a simple pattern involving a constant spacing of units in the sample.

Q.1 In addition to the assumption of ANOVA, the other point which is given due consideration by the statistician is “The stability of variance.”

Q.2 In any investigation, if it is possible to incorporate the “randomisation procedure” then it is customary to rely on “ Randomisation” to break up any “correlation among experimental errors”

Q.1 The most fundamental assumption to be followed by random variable for using the standard method (parametric statistic) or parametric inference is that the random variable follows normal distribution.

Q.2 The standard parametric techniques are not useful for estimating parameters and testing hypothesis about them.

Extraction is a process whereby the desired constituents of a plant are removed using a solvent. The primary ways for extraction of organic molecules of interest to biologists and medical investigators involve breaking open the cells. Cell rupturing is carried out in a variety of ways. The method used depends on the type of tissue used. For plant cells grown in cell suspension culture or for plant callus tissue, a French press or a sonicator can be used to break open the cell.

Animal husbandry is the most important economic activity in rural areas as livestock plays a vital role in the economy. Over 90 per cent of the milk production comes from small farmers, who are located in rural areas. Growing human population, increasing urbanisation, rising domestic incomes and changing lifestyles in the country have led to increasing demand for dairy products (Anita and John, 2001).

2. The berries are separated from the spikes and dried in the sun for 7-10 days.
3. When dried, the berries retain the characteristic wrinkled appearance of black pepper of commerce.

HORTICULTURAL CLASSIFICATION OF PLANTS

The Horticultural crops are majorly classified on the basis of its consumption and uses as fruits, vegetables, flowers, spices, medicinal, aromatic and plantation crops. Moreover, these crops have been further classified into various groups on the basis of their habitat, growth pattern, edapho-climatic requirements and uses. All branches of horticulture classified specifically as hereunder:

A Classification of fruits

1. Based on Climatic adaptability
   1. Tropical fruits: These fruit crops are grown in tropical climatic regions which are geographically located between the parallels of 23° 27' South (Tropic of Capricorn) and 23° 27' North (Tropic of the Cancer) of the equator. They are generally evergreen and very sensitive to cold. Eg. Mango, Pineapple, Banana, Papaya, Citrus, Sapota, Avocado etc.
   2. Sub-tropical fruits: Fruit crops are grown in between temperate and tropical climatic regions. They may be either deciduous or evergreen nature. Eg. Mango, guava, citrus, durian, jackfruit, bread fruit etc.

A seed (in some plants, referred to as a kernel) is a small embryonic plant enclosed in a covering called the seed coat, usually with some stored food. It is the product of the ripened ovule of gymnosperm and angiosperm plants which occurs after fertilization and some growth within the mother plant. The formation of the seed completes the process of reproduction in seed plants (started with the development of flowers and pollination), with the embryo developed from the zygote and the seed coat from the integuments of the ovule. In broad sense, seed is a material which is used for planting or regeneration purpose. Seed technological point of view, seed may be sexually produced matured ovule consisting of an intact embryo, endosperm and or cotyledon with protective covering (seed coat). It also refers to propagating materials of healthy seedlings, tuber, bulbs, rhizome, roots, cuttings, sets, slips, all types of grafts and vegetatively propagating materials used for production purpose. Quality seed, therefore, can be defined as the seed which fulfills the minimum requirements of getentic and physical purity, seed germination and vigour freedom from weeds and other crop seeds and other relevant seed standards.

Irrigation is one facet of the inputs which need to be carefully managed so that profits are maximized. Irrigation plays a major role in any agriculture crop production. One should be aware of different types of irrigation adapted in orchards or crop cultivation to become a successful grower. Irrigation is very important component of crop cultivation as sufficient moisture must be maintained in the soil for obtaining the optimum growth and good quality yield. The aim of irrigating a plant should be to wet the entire root zone without allowing any wastage of water beyond the root zone. The irrigation systems have to be properly devised so that the water requirements of the trees are met at the minimum expenditure without any wastage of water. Irrigation practices can be improved if a range of important factors like crop type, crop water requirements, climatic conditions, soil type, water quality, method of irrigation are taken into account.

Crop type

The type of horticultural crops grown influences irrigation practices. Annual vegetable and melon crops have high water requirement, hence irrigation management is extremely critical to their productivity during their relatively short life span (10-20 weeks). Perennial fruit crops tend to require less water and management, although critical, is not generally as critical as for annual crops.

Introduction

India contributes about 5% to the world's eggs and 2.25% to chicken production (FAOSTAT, 2013). Indian Poultry Sector has been one of the fastest growing components of Indian economy with an annual compound growth rate of about 6% and 12% in egg broiler production, respectively. Poultry sector accounts for about 1% of the India's Gross Domestic Product (GDP) and 11.7% of the livestock GDP (National Account Statistics, 2013). With a turnover of over ?600 billion, the sector provides employment to over six million people. The annual per capita availability has increased from 7 eggs in 1961 to 58 eggs in 2012; and poultry meat from 0.16 kg to 2.21 kg during the same period. However, the present availability levels are still far below the ICMR recommendations of 180 eggs and 11 kg meat per capita per annum. Ironically, consumption of poultry products has been highly skewed in favour of urban population. In fact, only 31% of the population residing in urban areas consumes 65% eggs and 70% of poultry meat and in a typical Indian village the egg consumption is not more than 10 eggs per capita per year. Despite higher prices of poultry products in rural areas, the penetrability and reach of poultry products have remained limited in rural India owing to fragmented markets and infrastructural bottlenecks. Sekhon and Tejinder (2007) have estimated that under a moderate growth scenario of 6% per annum in the Country's GDP the demand for meat and eggs is likely to shoot up to 9.7 and 15.32 MMT by 2021 and 2030, respectively. India would be easily able to meet this demand provided, the poultry egg and meat production continue to grow at the current levels.

Introduction

Increasing public concern regarding the use of pharmaceuticals in livestock feeding due to the emergence of drug resistance has led to an enhanced interest to plant derived bioactive compounds as alternative means to improve livestock health and production. Plants bioactive compounds are the plant secondary metabolites having pharmacological or toxicological effects in animals. Secondary metabolites are formed within the plants as well the primary biosynthetic and metabolic routes for compounds associated with plant growth and development, and are considered as products of biochemical deviate in the plant cells and not required daily for the performance of the plant. Some of them are found to have various important functions such as protection, attraction or signaling in the plants. Most species of plants seem to be competent in synthesizing such compounds. Plants with potent bioactive compounds are often characterized as both poisonous and medicinal, and a beneficial or an adverse effect may depend on the quantity eaten by the animal. Some tropical tree leaves and typical food and feed plants with bioactive compounds with less prominent effects, their intakes are usually considered as advantageous.

Introduction

Global warming is chiefly due to combustion of fossil fuels for multifarious energy needs, causing emission of greenhouse gases which trap energy from the sun leading to warming. These climate changes bring in variation in patterns and emergence of new zoonotic diseases to newer areas. These changes sometimes create conducive conditions for the propagation of insect vectors. History shows that most of the diseases have a direct correlation with climatic changes. The survival and propagation of pathogens are directly related to temperature and humidity etc. Extreme shifts in weather patterns resulting from global warming and climate changes adversely affect the ecosystem resulting in new diseases, re-emergence of earlier diseases including emergence of zoonotic diseases. The emergence of the new cholera strain O: 139 and outbreaks of Dengue, West Nile virus and Rift Valley fever in newer and non-endemic areas have been linked with the El Nino effect. The spread of disease agents may be facilitated by factors including environmental conditions, the presence and availability of suitable hosts, the arthropod's feeding behavior and host preferences.

Pulses are seeds of leguminous plants used as food. They produce dal rich in protein. The important pulse crops are greengram, blackgram, redgram, bengal gram, soybean, cowpea, peas, lentil and lathyrus. The total area under pulses in India is 29.81 m ha with a production of 25.42 m t and the productivity is 853 kg / ha. Pulses can grow both in rainfed and irrigated conditions.

Cowpea is a quick growing leguminous forage crop. It is usually grown mixed with cereal fodders and grasses to improve the nutritive value of the herbage. It contains 20 – 24 % crude protein, 43 - 49 % neutral detergent fibre, 34 – 37 % acid detergent fibre, 23– 25 % cellulose and 5 – 6 % hemicelluloses on dry matter basis. The digestibility of cowpea fodder is above 70%. Cowpea can be grown under partial shaded conditions. It is an excellent cover crop, which suppresses weeds and enriches the soil. Cowpea requires warm climate with good atmospheric humidity. It can be grown in kharif as well as in zaid season.

Fruits are an essential component of a human’s healthy diet. Fruits are used as a supplement to primary foods. When compared to grains, many fruits have far greater nutritional potential. The common fig is one of the most important and widely consumed fruits (Ficus carica).
