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).

The main objective of nanomedicine broadly defined as the comprehensive monitoring, repairing and improvement of all human biological systems, working from the molecular level using engineered devices and nanostructures to achieve medical benefit. Nanomedicine is the nanomachine of diagnosing, treating, and preventing disease and traumatic injury, relieving pain, and of preserving and improving human health, using molecular tools and molecular knowledge of the human body. Nanotechnology applications in medical science can be essential in achieving this goal. These applications involves extensive surveillance, control, creation, repair, and defence of all biological human systems, employing designed nanodevices and nanostructures which works in molecular level.

Genomics is the study of whole genomes of organisms, it uses a combination of DNA sequencing methods, bioinformatics to sequence, assemble, analyse the structure and function of genomes. In another words, it can be defined as it is the study of the structure, function, and inheritance of the genome of an organism. Moreover, genomics focuses on interactions between loci and alleles within the genome and other interactions such as epistasis, pleiotropy and heterosis. Genomics is divided into two basic areas: structural genomics, characterizing the physical nature of whole genomes; and functional genomics, characterizing the transcriptome (the entire range of transcripts produced by a given organism) and the proteome (the entire array of encoded proteins).

Most biological traits are controlled by a large number of genes, which, in addition to their additive effects, may interact with each other, and their expression might be altered based on a variety of environmental effects. Researchers who were among the first to use molecular genetics to the study of cattle began by employing DNA markers to locate genes or sections of the genome affecting features of interest. For instance, identifying a group of genes based on Genome wide association study (GWAS) provides evidence that a causal relationship between a phenotype and a single nucleotide polymorphisms (SNPs) may exist. These findings of GWAS, however, do not improve our understanding of complex traits in which many pathways may be involved. The growing use of genotyping technologies has generated a large quantity of genomic information on the dairy population. Since the draft sequence of the bovine genome was published in 2009 (Zimin et al., 2009), whole-genome sequence data of cattle have also become available.

Definition, Significance and Importance

Landscape design and gardening is the technique of design application to beautify our surroundings, our homes, office buildings and everywhere in open space with plants and garden features to give the soothing effect on the body, mind and soul. Rapid urbanization, industrialization with population explosion has been constantly depleting our natural resources through deforestation, ripping of hills and exposing them to erosion, pollution of rivers, streams and lakes with little understanding of the natural environment which supports human life. It is the application of the art and techniques of Landscape Gardening that can spell magic to our surroundings enhancing aesthetic beauty besides, improving and conserving environment. Besides, landscape beautification and ecological balance provision, other beneficial influence of gardens in human life have been researched and studied. Psychologists have found that access to plants and green spaces provides a sense of rest and allows workers to be more productive. Flowers convey our inner feelings sympathy, romance or celebration (pride and joy) or contrition in the most beautiful and delicate manner. Flowers are also used to express religious feelings. Interaction with gardens and natural spaces offers a variety of mental, physical and social beneficial influence for humans, ranging from stress reduction, quicker healing and mitigation of Attention Deficit Disorder in children to decreasing crime and air pollution. Studies throughout the world have proven the power of green spaces to improve human health. Recent studies in the Netherlands and Japan show that people with easy access to green space showed better health and lower mortality rates.

Entrepreneurship

Entrepreneurship is an activity which helps the entrepreneur to bring changes in the process of production, innovation in production, new usage of materials, creator of market etc. It is a mental attitude to foresee risk and uncertainty with a view to achieve certain strong motives.
The word entrepreneur derived from French verb ‘Enterprendre’ means “to undertake”.

An entrepreneur should have “creative and innovative ideas”. It refers to successful business men who strive hard not only for gain himself in his economic activities but also to grow in all spheres of life.

According to Joseph A. Schumpeter: Entrepreneur is one who innovates, raises money, assembles inputs, chooses managers and sets the commercial organizations going with his ability to identify them and opportunities which others are not able to identify and is able to fulfil such economic opportunities.

ABSTRACT

Cassava has developed importance mainly as an industrial crop due to its ability to store large quantities of starch (74% to 85% of dry weight) within secondary root structures. Cassava starch is exploited as a source of human food, feed for livestock and as raw material for the food processing and chemical industries. Research accomplishments during the last four decades helped India to have the top position among cassava growing countries with an average yield of 24 t ha-1. However several traits like starch quality, high protein , post harvest deterioration etc can be altered only through the development of transgenics. The present study summarizes the results of the experiments undertaken to optimize the protocol for the development of transgenic cassava through Agrobacterium mediated gene transfer. Friable Embryogenic Callus (FEC) was developed in the cassava var. TMS 60444 us ing Murashige and Skoog (MS) media with picloram (50μM). Experiments were conducted to study the efficiency of different Agrobacterium stains viz, AGL 8, GV3101, C58C1, LBA 4404 and EH105 in transforming FEC. The strains differed in their growth rate. The strains EH105 and AGL were slower in growth as compared to other strains and the protocol was modified accordingly. Among all the strains, EH105 resulted in maximum recovery of transgenic tissues. The paper also summarizes the present status of development of transgenic cassava along with future thrusts.

Introduction

Organic agriculture is defined by Food and Agricultural Organisation / World Health Organisation Codex Alimentarius Commission as “a holistic production management system which promotes and enhances agro-ecosystem health including biodiversity, biological cycles and soil biological activity. It emphasizes the use of management practices in preference to the use of off farm inputs. This is accomplished by using, where possible agronomic, biological and mechanical methods as opposed to using synthetic materials, to fulfill any specific function within the system”.

Abstract

Three-point bend test (three point bend ring-HDP/3PB) for five types (Good day, Butter bite, Marie, Krack Jack and Salted) of commercial biscuit brands (Britannia, Supreme, Parle, Lancer, Priya Gold and Dalmia) was developed using TA-XT2, texture analyzer and probable factors affecting the results were assessed. Maximum force to break the biscuits, number of fracture before break, thickness of biscuits and percent break point penetration were found in the range of 1006.5 to 3456.5g, up to 3, 4.2 to 6.3mm and 5.54 to 22.62%. The rupture of biscuits were observed on the basis of probe penetration into the biscuits and found that maximum resistance for penetration offered by Marie whereas minimum by salted biscuits, which was respectively the hard dough and fermented dough biscuit varieties. The analysis of variance for the results revealed that there is significant difference (P£0.01) in the maximum force of break for the biscuit types and brands individually or in combination. Difference in the thickness of biscuits was also found significant among types and commercial brands. The number of fractures was not consistent among the types as well as biscuit brands before reaching the maximum force of breaking the biscuit.

The financial and commercial book keeping that is generally practiced by dairies, the main purpose of which is to ascertain the total results of the business during a given period, does not answer the question whether the costs of processing of milk products and of the various operations involved in manufacturing, are reasonable. For this purpose, dairy plants have to keep detailed records of the expenditure incurred on different components and processes, for planning of production and controlling of costs. In large multi-product dairy plants, production is generally characterized by mixed and joint production and the different operating operations are interrelated. Thus, it becomes difficult to draw a distinction and allocate and apportion the consumption of various services and utilities to arrive at the cost of different operations of various products.
The Bureau of Indian Standards has developed three different sets of records on dairy accounts which may be used to record different information for cost and quality control. These records are:

A. Answer the following questions:

1.    What is NPN substances?

3.    Name few amides.

Ans. Urea (46.6% N) and Biuret (35%N)

4.    Name few amines:

Ans. Histamine from Histidine, Tryptamine from Tryptophan, Tyramine from Tyrosine, Betaine from Sugar beet pulp.

5.    Name few alkaloids.

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

The expanding number of people around the world necessitates an increase in the amount of food that is yielded. As stated by the Food and Agriculture Organization of the United Nations (FAO), global food production ought to be ramped up by a factor of two in the next few years in to meet the requirements of the growing global population in terms of consumption (FAO, 2006). This is because the global population is expected to continue growing at a rate of approximately one person every two seconds until the year 2050. It is possible that the predicted production disparity could be filled by making improvements in genetics, animal health, and the excellence of animal husbandry.

The production of animals has expanded significantly over the course of the last several decades as a direct result of the application of quantitative genetics in animal breeding. However, due to technological limitations, the use of genetic markers in breeding programmes has only been implemented to a relatively small extent (Deng et al., 2016). The concept of genomic prediction, which was first introduced approximately twenty years ago, has completely transformed the planning and execution of animal breeding operations.

Chikungunya has been emerged as an important public health problem in the Indian Ocean Islands and India recently. Epidemiological, geographical and demographic data suggested that 1.38 million people were affected by the disease in India in 2006. The actual incidence of the disease may have been higher but underreporting did not reveal the actual picture. A large proportion of those who became ill consulted private health care professional or sought alternative medical care such as Ayurveda or homeopathy not included in the data collected by Govt. officials.

During the epidemic, rural hospitals, private and public clinics flooded with victims of Chikungunya. The virus did not kill its victims but inflicted considerable pain and misery besides local, regional and national financial burden towards health care. Only National Institute of Virology (NIV) and National Institute of Communicable Disease (NICD) provided accurate diagnosis of the disease. The Chikungunya assumed epidemic proportions because viral agent mutated, the vectors discovered the new ways to spread and the host lacked immunity to fight the disease. Modern transport systems - cars, buses, trains and aircraft particularly the movement of humans played a key role in spreading the disease that helped to maintain man-mosquito man cycle.

Etiology: First isolated in Tanzania in 1953, Chikungunya is under genus Alphavirus and family Togaviridae. It contains a single stranded positive sense RNA with a length of 12 Kb coding 4 non-structural (nspl - nsp 4) and 3 structural proteins (E1-E3). Among the structural protein, El protein correlates with serological response in human hosts and also modulates penetration of the virus in the mosquito species. Genetic analyses and historical accounts suggest that the Chikungunya virus originated in tropical Africa and subsequently evolved into 3 distinct genotypes - the East African, the West African and the Asian genotypes. The Asian genotypes have a high degree of nucleic acid sequence homology among themselves but the African strains exhibit wider sequence diversity and have been shown to undergo genetic micro-evolutions even during the course of an epidemic. Prior to the 2006 epidemic in India, the 3 genotypes were restricted to the geographical areas only. Previous outbreaks in India (1963 and 1973) were caused by the Asian genotypes, but the 2005 epidemic in the Indian Ocean Islands and the 2006 epidemic in India have been attributed to the East African genotype which arrived in India 5 years ago.
