9.1. ITKS for Seed Treatment and Sowing

• Yield of almost all the crops depends on seed quality.
• Even if it is a quality seed, it should be a dried one because well dried seeds will have higher longevity and keeping quality.
• It better to change the seeds at least once in two years.
• To maintain the seed viability and prevent it from outside damage, the outer shell is not separated.
• The seeds are generally stored along with the leaves of neem (Azadirachta indica), pungam (Pongamia pinnata), notchi (Vitex negundo) and thumbai (Leucas aspera).
• Six weeks nursery period is enough for six months duration of the crop.
• Shallow sowing is followed in dry lands.
• Severing the broadcasted seeds in dry lands with soil.
• Dragging, over the fields, the thorny branches with weight over them for covering seeds the sown on dry lands.
• It is better to start planting from ‘Sani moolai’ (north east) of the field to get higher yields.
• It is better to perform sowing and planting operations during evening hours.

In India, there are two accreditation systems for authorizing Certification and Inspection agencies for organic certification. National Programme on organic Production (NPOP) promoted by Ministry of Commerce is the core programme which governs and defines the standards and implementing procedures. National Accreditation Body (NAB) is the apex decision making body. Certification and Inspection agencies accredited by NAB are authorized to undertake certification process. The NPOP notified under FTDR act and controlled by Agricultural Processed Foods Export Development Authority (APEDA) looks after the requirement of export while NPOP notified under APGMC act and controlled by Agriculture Marketing Advisor, Directorate of Marketing and Inspection looks after domestic certification. Currently 20 certification agencies have been authorized to undertake certification process.

National Programme on Organic Production

National Program on Organic Production (NPOP) was launched during 2001 under the Foreign Trade & Development Act (FTDR Act). The document provides information on standards for organic production, systems criteria, and procedures for accreditation of Inspection and Certification bodies, the national organic logo and the regulations governing its use.

GENERAL CHARACTERS

• Deuteromycotina includes the fungi in which the ‘perfect stage’(zygote, ascus, basidium) is either lacking or has not been discovered so far. Because of the apparent absence of any perfect stage or sexual phase, these fungi are commonly called ‘imperfect fungi’ or technically ‘Fungi imperfecti’.
• The characteristic feature of Deuteromycotina is the absence of sexual reproduction. The members reproduce only be asexual methods, and that too also chiefly by conidia, which develop on conidiophores.
• The conidia are produced either directly on the conidiophores or in some special types of fruiting bodies such as synnemata, acervuli, sporodochia or pycnidia.
• Fungi possess branched, septate and multinucleate mycelium except the unicellular yeast like members of Blastomycetes.
• Sexual reproduction is completely absent.
• Parasexuality is shown by some Deuteromycotina. Under this phenomenon, the process of plasmogamy, karyogamy and haplodization take place, but not at specified time or specified points in the life cycle of the fungus.

Resistance to disease in a host plants is a condition in which the plant conquer the pathogen’s attack and thus suffers small or no injury. Resistant hosts prevent or slow the development and reproduction of the majority of pathogen propagules that they come into contact with. Different plants defend themselves in different ways. Each kind of plant, probably, employ different defense mechanism against each of the pathogens that attack it. The defense barriers erected by plants are a co-ordinated system of molecular, cellular and tissue-based responses to pathogen attack.

There are various mechanisms of defense used by plants. For convenience, such mechanisms can be considered under two broads heads;

1. Pre existing or passive defense (Defense present on or inside the plant since beginning)

a. Pre existing structural defense

b. Pre existing biochemical defense

2. Post infection or active defense (Defense in response to attack by the pathogen)

a. Post infection structural defense

b. Post infection biochemical defense

The most abundantly and commonly available compounds in the plant kingdom are carbohydrates. They comprise saccharides viz.

Monosaccharides - glucose, fructose etc.

Disaccharides - sucrose, lactose, maltose etc.; and

Polysaccharides - starch, cellulose etc.

Cellulose is the major component of plant cell wall.

The active groups in carbohydrates are aldehyde (-CHO) and ketone (=CO). In addition, they contain hydroxyl groups as well. The chemical properties of saccharides vary depending upon the number of hydroxyl groups and the presence or absence of (–CHO) or (=CO) groups.

Abstract

Consumer now-a-days relies on manufacturing and processing standards, particularly to know what ingredients are present, due to dietary, nutritional requirements, or medical conditions (e.g., diabetes orallergies). Modified PCR and combination of PCR with other analytical tools have been successfully used for analysis of various parameters related to functional foods such as detection and quantification of beneficial as well as food borne pathogenic microorganisms, food allergens, raw material source, bioactive compounds, genetically modified foods. Multiplex PCR method has been found to be an efficient tool for simple, rapid, and reliable identification of Lactobacillus and Bifidobacterium in probiotic products. Food allergens like gluten, peanut, hazelnut etc. could be easily detected in foods using PCR, even if present in small quantities. BOX-PCR and PCR-DGGE analysis have been used for identification of bacterial diversity of a naturally fermented functional food (Enzyme). HPLC combined with real time -PCR were successfully used to quantify and analyse compounds of secondary metabolites like phenylpropanoid amides, which represent an important class of nutraceutical having strong antioxidant and chemotherapeutic effects in various transgenic tomato tissues. Detection of active compounds in natural plant products were successfully achieved using PCR techniques. In general PCR have gained more importance as it has high sensitivity, improved precision, wide dynamic range for quantification, genotype based and is quick method of detection and quality control of foods than traditional culture based methods.

Abstract

Prebiotics are the non-digestible food ingredients that beneficially affect the host by selectively stimulating the growth and/or activity of one or limited number of bacteria in the colon. These are heat resistant components which remain intact during the baking process; this allows prebiotics to be incorporated into every day food choices. Consumption of non-digestible ingredients allows the growth ofbio cultures by reaching the intestine unaffected by the digestion process resulting in improvement of digestive health. Prebiotics reach the intestine in an unaltered form and shows the prebiotic effect when there is an increase in the activity of healthy bacteria in the human intestine. The prebiotics stimulate the growth of healthy bacteria such as bifidobacteria and lactobacilli in the gut and increase resistance to invading pathogens. Functional foods increase consumer choice by adding prebiotics to every day food items such as cereals, biscuits, breads, table spreads, drinks, and yoghurts. By continuing to eat and drink common foods, but choosing functional alternatives (such as bread containing prebiotics) dietary requirements can be met, without significant changes to foodpreferences. Some common example of cereal based products containing prebiotics are oat-based prebiotic drink, Breakstone's and Knudsen live active cottage cheese, prebiotic yogurt- Attune and Muller vitality, multi-fruit drink enrich and flavoured water enrich, prebiotic flavoured water, prebiotic capsules, dried fruit bars, prebiotic powder- Biocare fructo-oligosaccharides, Newtree purplaisir chocolate spread. The claims are constipation relief, suppression of diarrhea and reduction of the risks of osteoporosis, atherosclerotic cardiovascular disease associated with dyslipidemia and insulin resistance, obesity and possibly Type-2 diabetes. At present, claims about reduction of disease risk are only tentative and further research is needed.

Abstract

The use of biosensors is growing in the food industry as a means to ensure food safety and quality because of its versatility in determining biological compounds. It is defined as analytical technique used for detection of analyte that combines a biological component with a physico-chemical detector. The most important contribution of biosensors in the food sectors is to control production processes and ensure food quality and safety by reliable, fast and cost effective procedures. Biosensors have been useful for the evaluation of food composition, particularly in functional food products fortified with phytochemicals, vitamins and minerals.. Biosensors are replacing conventional analytical tools since they offer advantages in size, cost, specificity, rapid response, precision and sensitivity. Future progress in the biosensor technology involves the development of nutraceutical release technology within packaging material where it can be used to trigger the controllable release of bioactive components and targeted delivery of protective agents into the food product. The growing consumer demands for safe and quality food has led the food industries to search for quick and reliable methods for which the applications of the biosensor technique in the field of food processing and quality control are found to be promising.

ABSTRACT

Satellite-based hyperspectral imaging became areality in November 2000 with the successful launch and operation of the Hyperion system on board the EO-1 platform. Hyperion is a push broom imager with 220 spectral bands in the 400-2500 nm wavelength range, a 30 meter pixel size and a 7.5 km swath. Prelaunch characterization of Hyperion measured low signal to noise (SNR<40:1) for the geologically significant shortwave infrared (SWIR) wavelength region (2000- 2500 nm). The impact of this low SNR on Hyperion's capacity to resolve spectral detail is studied for the Musiri and Tattayyangarpettai regions of part of Namakkal and Tiruchirapalli districts of Tamil Nadu state, India which comprises a diverse range of minerals with narrow, diagnostic absorption bands in the SWIR. Following radiative transfer correction of the Hyperion radiance at sensor data to surface radiance (apparent reflectance), diagnostic spectral signatures were clearly apparent including: green vegetation; talc; dolomite; crystalline limestone, chlorite; white mica and sericite. Though the derived surface composition maps generated from these image endmembers were noisy (both random and column), the spatially coherent and correlated well with the known geology. The interpreted and processed mineral map is given below. In addition, the Hyperion data were used to measure and map spectral shifts of <10 nm in the SWIR related to white mica chemical variations.

ABSTRACT

The Remote Sensing data volume is vast, so high processing capacity is required. It is impossible to update spatial data without the support of high performance of RS image management, retrieval, and change detection and pattern discovery. After introducing some background information including significance of SDI updating, feasibility and advantages of satellite RS imagery used to update spatial data, the framework of updating spatial and attribute information based on RS image is proposed. In the process, the integrated processing of raster data and vector data is very important, so some functions of RS image processing and GIS software should be fused. In order to extract the anticipated images from vast image database, effective retrieval technique is vital. RS image data mining and knowledge discovery is the synergy of Spatial Data Mining (SDM) and Image Data Mining (IDM). Oriented to the demands of SDI updating to intelligent information processing, some primary issues on RSDM are analysed. It is pointed out that updating SDI by satellite RS imagery will be potential advantageous in the future. RS Data Mining and Knowledge Discovery are very important and will play important roles in the future.

ABSTRACT

This paper demonstrates the ability of FTIR for analyzing compositional structures of naturally occurring crystals namely gypsum and calcite. As these two crystals occur in a wide variety of geological environments and are susceptible to compositional and structural changes influenced by pressure, temperature, crystallization fluids and so many other factors, these are extensively studied by geoscientists for interpretation of paleoenvironment, modeling diagenesis of sediments and deducing sediment maturity for hydrocarbon exploration, study of these two crystals is important. Naturally occurring gypsum and calcite crystals collected from Cretaceous marine deposits of Ariyalur area were chosen for the present study as extensive occurrences of hydrocarbons are reported from offshore region of Cauvery basin and exploratory works are going on in the onland region. It is observed that the vibrational spectra of studied crystals show specific patterns in terms of stretching patterns of O-H, C-O, C=O, SO₄ and CO₂. As FTIR offers fast, cost-effective, non-destructive method of analyses of natural compounds, as it is proven useful, it can be utilized extensively in academic research and commercial exploration activities by geoscientists.

ABSTRACT

Mangrove wetlands are well known as the dominant feature of the intertidal areas of the tropical and subtropical regions. Ecologically mangrove forests are important for their inherent biological productivity in the habitat and also by exporting organic matter produced into coastal waters. Apart from that mangroves act as bioshield against natural coastal hazards like cyclones, storms and tsunamis. Remote sensing coupled with GIS is an important tool in monitoring the coastal areas such as mangroves, where the physical survey is difficult and time consuming. Remote sensing has a wide range of products with higher spatial, spectral and temporal resolutions, the combination of which can be applied in different themes based on the requirement. The present study used multispectral, multi-temporal and high-resolution remote sensing data to map and monitor the distribution of mangrove forest of Pichavaram, south India over a period of 30 years. The study shows that the mangrove area had decreased from 628 ha to 411 ha from 1977 to 1994 and increased to 858 ha in 2006. The high resolution remote sensing data with 4 m spatial resolution was used to prepare the mangrove wetland map in 1:5000 scale.

ABSTRACT

Remote sensing, especially high resolution satellite data has a major role to play in locating (localizing) mineral targets. The present study is carried out on exploration and discrimination of magnetite ore deposits of Tirthamalai region of part of Dharmapuri district, Tamil Nadu, India, using IRS P6 LISS IV high resolution satellite data. The applicable image processing techniques and associated put forth of field knowledge is used in the present study. The image processing classifications namely band rationing, principal component analysis and contrast enhancement are carried out in visualizing images using ERDAS Imagine 8.7 software. The visual interpretation of FCC of digital data shows that the raw pixel values of iron ore bands in the blue ranges 95 to 120, green ranges 85 to 125 and red ranges 55 to 75 and provided better delineation for iron formations.

The interpretation of satellite data shows that the iron ore band exhibits in dark color, linear shape, fine texture and sharp contact with associated rock types. To rectify and reduce misinterpretation all above image processing techniques are undertaken along with the detailed filed-check in the selected test sites using GPS 178 and delineated the in situ iron formations. The interpretations show that the occurrence of few more iron bands and weathered formations along with massive formations in the region traced on the imagery since the absorptions themselves are different. The availability spectral absorption of iron formation is inferred highly in visible and near infrared region (0.9-1 Ìm). Remote sensing high resolution satellite data proved that the satellite parameters are important criteria and play a vital role in mapping of low-grade iron ore deposits of the Tirthamalai region of Dharmapuri district of Tamil Nadu state.

ABSTRACT

Topsoil erosion, loss of fertile soil and subsequent deposition in the reservoir as well as in the low-lying region are one of the major problems in the tropical mountainous region. Knowledge of sediment yield from the river basin is a prerequisite to address such issues. Rivers from the Western Ghat region of Uttara Kannada district bring lot of sediments causing siltation in their mouth. In the present study, sediment yield from a Venkatapur river basin in Bhatkal Taluk of Uttara Kannada district is estimated by Universal Soil Loss equation (USLE). Morphometric characteristics of the river basins that reflect sediment yield potential of the river basin are used to constrain the data obtained. Various parameters for USLE is derived from the IRS 1D LISS III image and data are handled in GIS environment. Sediment yields in the basin 101 tons/yr. Morphometric characters of the basin such as drainage density, bifurcation ratio, basin circularity (0.6) and form factor (0.43) suggest its low potential of sediment yield.

All over the world, garden designing has a historical back ground. Every continent has a definite style based on cultural heritage, agro-climate and the rulers. There are influences of one style over the other and subsequent change in gardening style also. However, there are some recognized orthodox styles like ‘English Garden’, ‘French Garden’, ‘Japanese Garden’, ‘Italian Garden’, ‘Dutch Garden’, ‘Mughal Garden’ etc. These are unique and true to their specific characters. Modern gardens all over the world have been greatly influenced by all these styles.

History and characteristics of these gardens are given below in order to make one acquainted with these styles.

Dutch Garden

Initially, gardening in The Netherlands was started in the form of abbey and monastery gardens (middle ages 500-1500 A.D.). Design of the medieval gardens usually was elongated rectangle, sometimes square, also divided with cross paths. These gardens were mainly meant for production of vegetables, medicinal herbs and fruits besides flowers.

During the Dutch renaissance (1500-1650 A.D.) further gardening activities initiated. After independence in 1609, it gained momentum and the change of garden style also noticed. Gardens became more open without walls. However, the basic design was on the basis of geometrical patterns - rectangular divided into small separate square. Axis of the garden was not in relation to the building. Leafy walk path (berceaux) was main structural elements created between various sub-divisions. Bulbous plants specially tulip was most preferred in the garden besides marigold, carnation, poppy, rose etc.

Chrysanthemum (Chrysanthemum morifolium) is a popular flowering plant grown for its magnificent flowers in wide range of colour. There are various size of flowers like mini, small and large. Forms of the flowers also vary from ball shape to spider type. In ornamental gardening, Chrysanthemum is used as bedding as well as pot plant. Cut-flowers are also very popular for vase decoration and commercially important. Flowers of the small-flowered cultivars are also used as loose flowers for making garland and floral ornaments.

Classification

There is huge diversity in the form and types of Chrysanthemum. Therefore, one has to know the various types of flowers, growth habit and their use in the gardens.

Parks occupy a unique position in our social life and a common facility to the community for pleasure and utility. The importance of park in urban areas is much more than other areas as these are the only outing places for urban people. Designing park needs careful consideration regarding features, plants and facilities for utility purpose. Roads for public movement, sitting arrangements, flowering and shady trees, flower beds, children’s corner are some of the basic requirements. Free flowering ornamentals requiring less maintenance should be included in the design.

Purpose

Parks are very purposeful in our daily life especially in urban areas. At present provision of parks in a city is must as these provide an open space and an opportunity for outing. Relaxation of body and mind after stressful working or even daily routine work is a must. Parks are the ideal places for such activities, especially very useful for children and elderly people.

Classification

Parks are generally classified according to its type and fulfillment of purposes. Sometimes, a particular theme or type of plantation is followed. Parks are finally categoriesed and named accordingly. Various common classifications are as follows.

The newly synthesized autopolyploids, having few or more undesirable features, e. g; meiotic instability, low seed setting and late maturity etc, are usually not suitable for immediate commercial use, are known as raw polyploids. This is specifically more applicable for those sexually propogated polyploids which are developedfor seed. In early generations due to polyploid chromosome constitution and polysomic inheritance they predominanantly do not breed true. Further more, due to meiotic instability chromosome number in their progeny is not always constant or equal to as in synthesized autotetraploid which may vary from few more to few less than the standard autotetraploid. The raw polyploids usually reverts back to diploid parental constitution due chromosome elimination (Randolph and Fischer, 1939). The mechanism responsible for reverting back to diploid status is similar to that of which give rise haploids from diploids. Presently cases are known where either spontaneously or due to specific treatments the chromosome number was reduced to half in somatic tissues. The phenomenon causing such chromosomal reduction is termed as somatic reduction or reduced mitosis Earlier reports suggested it probably to be caused due to spindle organizer abnormalities or some other unknown mechanism/s. The treatment of seed or seedling by colchicine, chloramphenicol and paraflurophenylalanine are reported to have induced chromosome reduction and production of haploids.

2.1 Particle Size Distribution Analysis

Soil is composed of inorganic particles and organic molecules of varying size and shape. The expression of the proportion of the different size inorganic particles is termed as ‘soil texture’. It is one of the most important basic characters being little changed by cultivation or other practices. Particles are arbitrarily distinguished into following groups on the basis of their diameters.

25.1 Determination of Available Micronutrient cations (Zn, Cu, Fe and Mn) in Soil

The available micronutrient cations (Zn, Cu, Fe and Mn) can be estimated in a single extraction with diethylene triamine pentaacetic acid (DTPA) as proposed by Lindsay and Norvell (1978). DTPA has the excellent property to combine with free metal ions in the solution forming soluble complexes. The stability constants of metal-DTPA complexes make DTPA as a most suitable extractant for simultaneous complex formation with Zn, Cu, Fe and Mn. In calcareous soil DTPAextractant may result overestimation due to excess dissolution of CaCO₃, causingrelease of occluded micronutrient cations which are not plant available. To avoid this excessive dissolution of CaCO₃, DTPA is buffered at pH 7.3 using triethanol amine (TEA). At this pH major part (3/4^th) of TEA is present as HTEA⁺ (protonation) and exchanges for Ca and Mg ion from the soil exchange site. This increases concentration of Ca and Mg in the solution phase and suppresses dissolution of CaCO₃. The DTPA has the capacity to form complex with each of the micronutrient cations 10 times of its atomic weight and it ranges from 550 to 650 ppm depending on the micronutrient cation.

The amount of cation in the extract is determined on an atomic absorption spectrophotometer (AAS). The experimental condition such as shaking time, DTPA concentration, pH and temperature during shaking influence the amount of Zn, Cu, Fe and Mn extracted. Increase in shaking time and temperature markedly influence the extractability of these cations.

A forest is a large area dominated by trees. Many definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing and ecological function. Although a forest is usually defined by the presence of trees, under many definitions an area completely lacking trees may still be considered a forest if it grew trees in the past, will grow trees in the future, or was legally designated as a forest regardless of vegetation type. According to the Food and Agriculture Organization, forests covered 4 billion hectares or approximately 30% of the world’s land area in 2006. Forests are the dominant terrestrial ecosystem of earth, and are distributed around the globe. Forests account for 75% of the gross primary production of the earth’s biosphere, and contain 80% of the earth’s plant biomass

Classification Of Forest

Forests have been classified in different ways. Forests can be classified on the basis of method of regeneration, age, composition, object of management, ownership, canopy density, stand density or growing stock.

Trees have been used in cropping systems since the beginning of agriculture. Throughout the world, at one period or another in its history, it has been the practice to cultivate tree species and agricultural crops in intimate combination. In the tropics, human beings underwent a transition from hunting/gathering to the use of domesticated plants and livestock. As a part of the process they cut down trees, cleared the debris by burning and sowed crops in the ash- enriched soil. It was the ‘slash-and-burn’ agriculture, a primary forerunner of the present day agroforestry and a practice that might have originated in the Neolithic period, around 7000 BC.

There are innumerable examples of traditional land-use practices involving combined production of trees and agricultural species on the same piece of land in many parts of the world. Trees were an integral part of these farming systems and they were deliberately retained on farmlands to support agriculture. These practices are now known as agroforestry. However, the ultimate objective of these practices was not tree production but food production.

Weeds have been existing on the earth ever since the man started domesticating /cultivating plants and animals around 10,000 B.C. and recognized as a problem since then. The battle against weeds is a never ending one and often the costliest agronomic input for successful crop production. Weeds are most under estimated crop pests in tropical agriculture although they cause higher reductions in crop yields than other pests and diseases. Of the total annual loss of agricultural produce from various pests in India, weeds roughly account for 37%, insects for 29%, diseases for 22% and other pests for 12%. Weeds decrease quantity and quality of the produces [food, fibre, oil, forage/ fodder, animal products (meat and milk)] and cause health hazards for humans and animals. Therefore, weed control is very important for a successful crop production.

Indian agriculture, accounting for 25% of the nation’s Gross Domestic Product (GDP), 15% of exports and 60% of the employment continues to be the mainstay of economy. Having achieved laudable success in agricultural production in the last 50 years (50 Million ton to 210 Million ton) India has transformed herself from a food deficit country to a food surplus country. Still there are many challenges, which Indian agriculture is facing, in a fast changing technical and socio-economic scenario. Relating to the natural resources and production base, water has emerged as the most crucial factor for sustaining the agricultural sector. India accounts for 16 percent of the world’s human population and nearly 30% of the cattle with only 2.4% of the land and 4% of the water resources.Even if the full irrigation potential is exploited, about 50% of the country’s cultivated area will still remain unirrigated, particularly with the current level of irrigation efficiency. The share of water for agriculture would reduce further with increasing demand from other sectors. But the water demand for agricultural purposes is estimated to increase in order to produce more cereals, horticultural produce and raw material for a fast expanding food industry. Efficient management of water is, therefore, key to future growth of Indian agriculture. The requirement of water by all sectors in 2025 is estimated to be 105 M ha m (Water Resources Development in India, 2010). Share of water for agriculture is expected to get reduced from the present level of 85 % to 69 % by 2025. On the other hand, the actual agricultural water demand is estimated to increase from 470 Billion Cubic Meters (BCM) in 1985 to 740 BCM in 2025. During the same period, the demand for non-agricultural use of water will multiply fourfold from 70 BCM to 280 BCM. The water use efficiency (WUE) in Indian agriculture, at about 30-40%, is one of the lowest in the world, against 55% in China.

As early as in the 18^th century, the anaerobic process of decomposing organic waste was known. During 19^th century, it became clear that anaerobic bacteria are involved in the decomposition process (DST, 1981). Since that time, the applications of anaerobic digestion have grown steadily, in both its microbiological and chemical aspects. The process of anaerobic digestion possesses a double advantage i.e. the process in addition to providing good quality manure also supplies a large volume of combustible gas. Anaerobic digestion provides some exciting possibilities and solutions to such concerns as alternative energy production, handling of human, animal, municipal and Agro-industrial wastes safely, controlling environmental pollution and expanding food supplies. The technology of anaerobic digestion (Kumar et al., 2015) has not yet realized its full potential for manure and energy production even in developed and industrialized countries. In developing countries expansion of this technology has been hindered because of the need for better economic initiatives, organized supervision, proper training and education.

During twentieth century, the method of anaerobic fermentation or digestion was successfully applied by sewage chemists. A considerable amount of research work was carried out by sewage chemists on different aspects of the digestion process and sludge digestion plant, were installed. The gas produced was used for burning as domestic fuel, operating machinery and for tractors. In this context, the studies on anaerobic digestion of cattle dung and vegetable waste has been important. The work is particularly important ones in the Indian context as long as gas production and plant design efforts are concerned. For research on anaerobic digestion energy part (methane generation) received more attention since the early decades of this century when research into bio digestion had gradually begun to take shape. Fertilizer aspect received occasional attention a couple of decades later. The engineering and micro biological aspects of gas production remain a dominant preoccupation even up to 1990s. Emphasis on the energy aspect still dominates in many parts of the world today.

History of Social Networking Services

The notion that individual computers linked electronically could form the basis of computer mediated social interaction and networking was suggested early on. There were many early efforts to support social networks via computer-mediated communication, including Usenet, ARPANET, LISTSERV, bulletin board services (BBS) etc.

Early social networking websites included Classmates.com(1995), focusing on ties with former school mates, and SixDegrees.com(1997), focusing on indirect ties. User profiles could be created, messages sent to users held on a “friends list” and other members could be sought out who had similar interests to yours in their profiles. Whilst these features had existed in some form before SixDegrees.com came about, this would be the first time these functions were available in one package. Despite these new developments (that would later catch on and become immensely popular), the website simply wasn’t profitable and eventually shut down. It was even described by the website’s owner as “simply ahead of its time.” Two different models of social networking that came about in 1999 were trust-based, developed by Epinions.com, and friendship-based, such as those developed by Jonathan Bishop and used on some regional UK sites between 1999 and 2001. Innovations included not only showing who is “friends” with whom, but giving users more control over content and connectivity.

Introduction

Poultry farming is an emerging activity for enhancing nutrition and providing livelihood support to the farmers of this country. Since two decades, this component emerge as the fastest growing segment of agriculture where the broiler segment having a growth rate of more than 10% and the egg production 5-6% per year. As per the report by USDA’s Agricultural Marketing Service, India has one of the world’s largest and fastest growing poultry, ranked third in egg production (FAOSTAT) and sixth in broiler meat production. Poultry farming is lucrative because there is minimum investment to start, rapid return, high feed conversion ratio and provides continuous source of income for the farm.

Introduction

The animals which man has domesticated over the years to meet his own needs for food, clothing, power or companionship include cattle, buffalo, sheep, goats, horses, pigs, cats, dogs and poultry. Domestic animals like most other animal forms existing on earth including human beings, are the result of a long evolution and therefore each other and indeed to all living beings. Much has been learned or better understood about the physiology of these animals through comparative study on the other animal forms, though many a time these animals have served as experimental models for studies designed to gain knowledge about human physiology. Dog and goat for a long time yielded to such experimentation. The domestic animals have been used for obtaining information on their physiology per se only recently and most experiments have been designed to understand better the mechanisms related to production potential of these animals in terms of meat, milk and wool. Knowledge is also gained by the study of sick and abnormal individuals or through surgery. Animal ethology (study of behaviour) is a comparatively recent discipline which has contributed abundantly to our understanding of the behaviour of animals in relation to their productivity.

The place of domestic animals in nature is objectively described by placing them along with other living organisms in the accepted scheme of classification as formulated by the biologists. The domestic animals belong to the Animal Kingdom, which like the plant kingdom, is divided into a number of major categories, the Phyla. The animal Phyla range from the relatively simple protozoa mostly single celled forms, to the chordata which encompasses backboned animals, including domestic animals and human beings. This scheme of classification is based on the concept of evolution of life and the animals are classified on the basis of closeness or the distance of their relationship. The life cycle of the animal (Ontogeny) is said to repeat the evolutionary development of the animal (Phylogeny).

The domestic animals belong to the phylum Chordata, sub phylum Vertebrata, characterised by the presence of a back bone or vertebral column. They are further classified to belong to class Mammalia and sub class Eutheria. The cow, buffaloes, goat, sheep etc. belong to order Ungulata in sub class Eutheria. The horse and asses belong to order Perissodactyla. The cats and dogs belong to order Carnivora. The poultry belong to the order Galliformes in Class Aves.

I. PUBLIC POLICY CONCERNS

The working of the Trade Related Aspects of Intellectual Property Rights Agreement (TRIPS) Agreement, 1995 along with World Intellectual Property Organization (WIPO) and the jurisprudence developed for the last twenty years is a testimony to the fact that although TRIPS is geared to promote the protection of intellectual property rights internationally, yet some controversial public policy issues need to be addressed and solutions devised for addressing these public policy issues otherwise there is a possibility of seeing the demise of TRIPS Agreement or sidetracking it by some other methods which may not be conducive for maximizing the welfare of the international trading community. As all of us know that intellectual property and international trade are mutually inclusive and the minimum standards set forth in the TRIPS Agreement are economically value oriented. The trade offs among and between the members of the WTO need to be balanced on an even keel, otherwise the possibility of camaflouging the TRIPS Agreement and the attendant jurisprudence becomes real. The TRIPS Agreement addresses seven categories of IP rights such as; Copyright and related rights; Patents; Trademarks and Service marks; Geographical Indications; Undisclosed Information or Trade Secrets; Industrial Designs ; and Layout Designs of Integrated Circuits and read with other WIPO Treaties obligates the members of the World Trade Organization (WTO) to reduce distortions and impediments to international trade by taking into account the effective and adequate protection of intellectual property rights as well as the procedures for the enforcement should not become barriers to international trade. The TRIPS Agreement also recognizes the need to cater to the special needs of the developing and least developed countries.

I. INTRODUCTION & OVERVIEW

Intellectual property rights may be defined as the legal relationships that arise out of an individual’s creative gifts and the communication to society of his or her intellectual creations. Intellectual property is challenging as well as rapidly widening horizon of law. The purpose of law is to encourage and reward creativity and intellectual effort. The prominence of this branch of law in India is partly due to India’s economic structure and its geographical position in the world. Many international companies operate in India either directly or through licensees or agents. Numerous goods, services, and technological developments have overseas origins. Foreign companies often control their interests through contract but they invariably do so by means of copyright law, obtaining of patents or by registration of trade-marks and designs. It follows that in particular circumstances intellectual property remedies are most convenient method of maintaining control, or at least a useful adjunct to other remedies based on contract. Another important factor is the upsurge in “piracy” that is occurring not only in India but also in almost every other part of the world. Piracy may originate outside India, or, it may also originate in lndia. While devising legal apparatus for the welfare and protection of creative people, we must not lose sight of the public interest in the greatest measure of access to information and culture. Intellectual property rights are significant wealth- creating assets and their protection and commercialization are of increasing economic significance. In past the value of such rights was often overlooked and it is only in recent years that the economic potential of intellectual property has started receiving greater recognition. The dawn of the third millennium which has led to the emergence of knowledge capitalism with emphasis on intangible assets such as knowledge, competencies and intellectual property is a defining movement in the history of mankind. It is a defining moment in the history of mankind because the historical forces set in motion by the digital revolution has spawned a new civilization characterized by path breaking inventions and technological innovations and the opening up of the electronic frontier. It is an age of digital renaissance which combines the marvels of the Age of Discovery and the excellence of medieval Renaissance rolled into one. As a result of the information technology revolution there is a transition from industrial society to information society. Convergence of computer networks and communication technologies facilitated by the digital revolution has given birth to Cyberspace which in turn has ushered in knowledge economy. Hence, the intellectual property law faces challenges. In this background the concept, nature and development of intellectual property rights are proposed to be examined. The paper will be divided into V more parts. Part II of the paper will outline the meaning concept of intellectual property and range of subject matter protected by law, part III will examine the jurisprudential justifications of intellectual property protection, part-IV will explore the evolution and development of intellectual property rights under international law, part-V will demonstrate the evolution and development of intellectual property rights under Indian law. And part-VI will conclude the subject.

Marketing management refers to distribution of the firm’s product or service to the customers in order to satisfy their needs and to accomplish the firm’s objectives.

Marketing includes developing the product or service, pricing, distribution, advertisement, merchandising, doing personal selling, promoting and directing sales and service to customers.

Marketing is an essential function because unless the firm has a market, or can develop a market for its product or service, other functions of staffing, producing and financing are futile. Marketing functions are schematically given below :

The UNFCCC (United Nation Framework Convention on Climate Change) has defined climate change as “a change in climate which is attributed directly or indirectly to human activity that alters the composition of global atmosphere which is in addition to natural climate variability” (UNFCCC, 2008). Ruminant animals, such as cattle, sheep, buffalo, and goats, are unique due to their special digestive systems which can convert otherwise unusable plant materials into nutritious food and fiber. This same helpful digestive system, however, produces methane (CH₄), a potent green house gas (GHG) that can contribute to global climate change. Livestock production systems can also emit other greenhouse gases such as nitrous oxide (N₂O) and carbon dioxide (CO₂). The most important GHG?s are CO₂, CH₄ and N₂O, which have increased in the last 150 years and have different global warming potential. According to Sejian et al., (2011) and Solomon et al., (2007), the warming potential of CO₂, CH₄ and N₂O are 1, 25, and 310, respectively. Taking into account the entire livestock commodity chain – from land use and feed production, to livestock farming and waste management, to product processing and transportation –Livestock?s Long Shadow attributes about 18 percent of total anthropogenic GHG emissions to the livestock sector (FAO, 2006). The Intergovernmental Panel on Climate Change (IPCC), convened by the United Nations, has reported evidence that human activities over the past 50 years have influenced Global Climate through the production of GHG, which results in increased absorption in the atmosphere of infrared radiations emitted from the earth?s surface. The accumulation of GHG results in increased global temperature which in turn can increase annual precipitation in high rainfall regions and decrease precipitation in regions of low rainfall (Gerstengarbe and Werner, 2008). This will affect water supplies, distribution of deserts and wet areas, the range and number of pests that affect plants or diseases and biodiversity.

From very early times, humans were astonished, fascinated and frightened by the weather events and the dynamism of changes that weather brought around them. Human beings have attempted to predict the weather informally for millennia, and formally since the nineteenth century. He has tried to predict or forecast the weather mainly based on many indicators around. In the earliest record of weather forecast, the Babylonians have predicted the weather from cloud patterns as well as astrology in 650 BC. In 904 AD, Ibn Wahshiyya, an Iraqi alchemist and agriculturist in his work Nabatean Agriculture have discussed the behavior of plants and animals also along with atmospheric, planetary, solar and lunar signs in weather forecasting. This is perhaps the first work that have discussed about the animal and bird indicators for weather forecast. Though there are a variety of end uses to modern weather forecasts, indigenous knowledge and application of weather forecasts were mainly for agricultural operations. Farmers have to rely on weather forecasts to decide on what work has to be done on any particular day. They are astute weather watchers and are quick to recognize weather that is either favourable or unfavourable to their production systems. In traditional weather forecasting, the farmers has identified a set of indicators and developed a reliability factor for each of them. Predicting weather is also an important cultural component for farmers, as it is common for farmers to discuss weather indicators on the street, markets and with family members.

Farmers have used traditional knowledge to understand weather and climate patterns in order to make decisions about crop and irrigation cycles. This knowledge has been gained through many decades of experience, and has been passed on from previous generations, and the knowledge is also adapted to local conditions and needs. But the scientific forecasts are formulated at a much larger scale and so access to get location specific rainfall forecast to take proper decision at the farm level is very limited. Besides forecasting weather, the farmers has also evolved several coping strategies in rain-fed systems across the world and so today many international development agencies, universities and research institutions have started focusing on indigenous knowledge and have incorporated it in development perspectives.

Entrepreneur

The word “Entrepreneur” is derived from the French verb ?Entreprendre?. It means ?to begin something? or ?to undertake?. In the early 16th century the Frenchmen who organized and led military expeditions were referred as ?Entrepreneurs?. In the early 18th century French economist Richard Cantillon used the term entrepreneur to business. Since that time the word entrepreneur means one who takes the risk of starting a new organization or introducing a new idea, product or service to society. An entrepreneur is a person who starts an enterprise. He has right to own his business and to make a profit. Some economist says that entrepreneur is one who is willing to bear the risk of a new venture if there is a significant chance for profit. Others emphasize the entrepreneur?s role as an innovator who markets his innovation. Still other economists say that entrepreneurs develop new goods or processes that the market demands and are not currently being supplied. Different researchers have elaborated qualities of Entrepreneurs. Schumpeter said that entrepreneurs are innovators who use a process of creative destruction of the established ways of creating/doing existing products and services, to set up new products, new services. David McClelland proposed that an entrepreneur is a person with a high need for achievement. He is energetic and a moderate risk taker. Peter Drucker said that an entrepreneur searches for change, responds to it and exploits change as an opportunity. In the words of Albert Shapero, Entrepreneurs take initiative, accept risk of failure and have an internal locus of control. Entrepreneurship as explained by various scholars laid emphasis on a wide spectrum of activities such as self employment of any sort, creation of organizations and innovation.

Livestock rearing provides triple benefits of income, employment and nutritional security to the society and is important source of subsidiary income to small/marginal farmers and agricultural laborers. Finance is a prerequisite and of paramount importance for setting up of a livestock enterprise whether a dairy farming unit for milk production, sheep or goat unit, piggery unit, dairy/poultry processing unit etc. Provision of credit/loans for the purchase of livestock, feed, veterinary services and insurance against the loss of valuable productive assets play an important role in encouraging new investments in the sector and also in coping with difficult problems such as draught and diseases. Decisions about credit are often most important judgments that people in the livestock enterprise must make. These decisions often determine whether individuals operating in input, production, processing and services based livestock enterprise would succeed in making profit.

Abstract

The Himalayas of Himachal Pradesh is prone to landslides due to inherent geodynamic conditions, rainfall and anthropogeny. Besides multi-variate studies on the landslides of Himachal Pradesh, instrument based early warning system was attempted by taking Jhakri landslides as the test site. Various instruments viz; piezometer, vertical inclinometer, Rain gauge, etc. were installed and the paper discusses about the methodology adopted in the installation of the instruments and the observations made from the instruments. While Piezometer did not reveal much information, the Tiltmeter showed minor movements.

Abstract

The landslide is a disaster which causes rampant loss to life, property and ecosystems. With increased awareness and technological development, the number of monitoring stations near hazardous regions have increased. To give warning prior to the occurrence of a landslide, the soil/rock mechanics of the underlying bed needs to be studied and understood. This paper examines the current literature and elucidates some features of state-of- the-art landslide monitoring systems.

Keywords: Field based sensors, Wireless sensor network, Landslide monitoring

INTRODUCTION

Advancements in technology have helped us to understand nature better than before, yet the geotechnical parameters causing landslides could not be quantified accurately. The efforts taken in predicting landslides are clearly moving towards this objective and this can be seen by the number of monitoring stations that have been setup in landslide prone areas around the world. The data that is obtained at each location is important in understanding landslides. Each location is unique in terms of soil properties, groundwater, inclination of the slope and weather conditions and consequently, each deployment is unique.

The paper narrates the instrumentation based forewarning systems functioning around the world. The paper discusses these aspects hierarchically viz; Landslide prone areas in India, geotechnical instrumentations and their merits, influence of rainfall on landslides, correlation between rainfall and pore pressure, the relevance of different systems for different scenarios etc.
