I. MANDATE OF COPYRIGHT LAW

The importance of intellectual property rights has arisen in recent years to a great extent. The law of copyrights protects original forms of expression i.e. Novels, Movies, Musical compositions and computer software etc. Earlier it was mainly confined to the -published Work and owner of it could prevent others from getting it published in the form of books or articles in order to get benefit in terms of money or goodwill or reputation. In case of such undue enrichment, the owner had a valid cause of action. The owner of the copyright has a valid cause of action against the violator. At present even in case of its adoption and translation or abridgement, it is obligatory to have consent of author. The main purpose and object of copyright law is to protect the expression in any other form from unauthorized use. Since 1847, the copyrights law is in developing stage so, many legislations has been enacted.1 With the changing of times, the meaning of expression also changes and the style of exhibit the things also changed. The right of author who gives expression in any form is protected from unauthorized use.

Directing is concerned with telling subordinates what to do and ensuring that they do it as best as they can. It includes assigning tasks and duties, explaining procedures, issuing orders, providing on-the-job instructions, monitoring performance, and correcting deviations.

Directing must have two dimensions, namely, i) magnitude and ii) aim or direction.

The directing function includes the following:

1. Supervising
2. Guiding
3. Leading
4. Motivating, and
5. Communicating

Materials Management deals with purchasing and controlling of the materials used in the production process.

Materials (Goods) Planning and Control

Decisions to be taken in this are:

• Amount of materials needed for output desired
• Amount of inventory and its storage and reordering
• Vendor relations
• Quality materials and price per unit
• Quantity and time of order
• Methods of receiving and transporting
• Handling of defective materials and stock

Policies and procedures should be established so that most of these decisions become routine in nature. When exceptions occur, the concerned authority should correct them.

Livestock wealth is very precious for a developing country like India. In India, animal husbandry is no longer a subsidiary to agriculture or a backyard vocation. Animal husbandry has metamorphosed into an industry and the latest reports suggest that the contribution of animal husbandry sector to the GDP of the nation is substantially higher despite the meager input. Animal husbandry offers a better scope for marginal farmers whose income from agriculture is dwindling fast due to vagaries of monsoon, fragmentation of landholdings, pest problems, poor pricing etc. Though the growth of livestock industry is very promising, in order to make India a global leader in animal husbandry, it is imperative to integrate it with developments in other fields. The developments in Information Technology over the past few decades are tremendous and offer great potential in improving animal health through various measures like effective disease forecasting, rapid and accurate disease diagnosis, modern therapeutic measures etc.

Veterinary Informatics is the discipline concerned with the application of information science, engineering, and computer technology to support veterinary health care. Veterinary informatics and the larger field of medical informatics is often called health care informatics or biomedical informatics and forms part of the wider domain of e-health. Applications of Information Technology in different aspects of animal health are discussed below.

The most of the animal population of the world?s lies in regions where frequent seasonal stressors adversely influence the health and productivity. The adaptation of animals to thermal stress is a physiological; biochemical process under endocrine control opens new opportunities to use of endocrine regulation as means of improving thermal tolerance. The animals raised in the semi-arid tropics, usually exhibit low productivity because of shortages of feed and harsh climatic conditions (Maurya et al., 2004). Heat stress can impact animal production and profitability in dairy cattle by lowering feed intake, milk production and reproduction. The animal production is affected by elevated ambient temperature which intern affects the availability of quality feed fodder and water. The indirect effects of climate driven changes in animal performance result mainly from alterations in the nutritional environment of the grazing livestock (Topp and Doyle , 1996). In tropical region most of the time is being spent by animals in the search of feed and fodder. The excess walking stress in the livestock reduces their body condition score and oftenly animal exposed to negative energy balance (Maurya et al., 2010). Under present climate conditions, the lack of ability of animals to dissipate the environmental heat determines that, in many areas in the world, animals suffer heat stress during, at least, part of the year. Heat stress has a variety of detrimental effects on livestock (Fuquay, 1981), with significant effects on milk production and reproduction in dairy cows (Johnson, 1987). The severity of stress and milk production by a cow depends on THI, length of heat stress period, air flow, size of cow, dry matter intake, water availability and coat colour.

At the moment India is world leader in milk production, closely followed by the USA, with a production volume of 84 million tons. More than half of the milk is produced by buffaloes. India has about three times as many ?dairy? animals as the USA, the vast majority (over 80 percent) being kept in herds of 2 to 8 animals. Annual milk yield per dairy animal is about one tenth of that achieved in the USA and about one fifth of the yield of a New Zealand dairy cow. As per India?s National Dairy Development Board (NDDB), the country produced 121 mt of milk in 2010-11 fiscal, which comprised about 17% of global production.

Livestock are homeotherms and has to maintain their body temperature at a fairly constant level through various means of heat gain and heat loss mechanisms. In order to survive in an environment for longer period the energy gain must equal to energy loss. The remarkable interaction has occurred between climate, soil, plants and animals during course of evolution. The maintenance of high level of production in hot regions is difficult as the large amount of heat has to be dissipated besides heat imposed by the environment. Similarly in cold regions, the animal has to produce extra heat to meet the thermoregulatory demand. Considerable variations occur between different species, and between different individual within a species in their capacity to adjust to environmental stress. The farm animals prefer an internal body temperature range from 36-40°C. Normal body temperature of livestock species are:

Cattle: 101-102^oF, Buffalo: 100.5-102°F, Sheep: 102-103°F and Goat: 102.5-103^oF

All the metabolic reactions are under control of various enzymes. The optimum ranges of temperature for activities of these enzymes incidentally fall in the range of normal body temperature. The body keeps its core temperature constant at about 37°C by physiological adjustments controlled by the hypothalamus. A group of neurons, located in anterior hypothalamus, are sensitive to change in skin as well as blood temperature. This hypothalamic centre acts as a “thermostat”. When core body temperature deviated from the thermostat temperature, numerous thermoregulatory mechanisms are initiated to bring back the core body temperature normal. However, in certain instance eg. fever the set point temperature of thermoregulatory control centre is raised. The hypothalamic thermostat works in conjunction with other hypothalamic, autonomic and higher nervous thermoregulatory centers to keep the core temperature constant. Some of these thermoregulatory responses are involuntary, mediated by the autonomic nervous system, some are neurohormonal and others are semi-voluntary or voluntary behavioral responses.

The establishment and the longevity of the organisms from one to complex multiple cells are controlled both by climate and weather in a region. Climate(macro level physical factor) of a region permits a particular organism to initiate its establishment, while the prevailing weather (micro level of the climate factor) which is known to occur within that climate controls the growth and multiplication of the selected organisms and thus proving the immense need of both climate and weather to living organisms. Within this science, when the weather is favorable for a particular organism throughout the year in a region, which cause disease to higher organisms then that region is termed as endemic region to a particular disease, where the management is focused towards strategical(long term) and tactical(short term) approaches. When in a year, from few weeks to few months the weather may be highly favorable for the outbreak of a particular disease, then that region is named as epidemic region for that disease and by establishing scientific link between weather and disease causing organism, it is possible to forecast / predict disease initiation in time and practice tactical management. Among the weather factors, temperature(both maximum and minimum), rainfall (amount and its distribution), relative humidity(both maximum and minimum) wind speed, dew, fog and mist would influence the organisms causing disease in livestock both in positive and negative terms. This is the new emerging area in the field of animal climatology and an attempt has been made to integrate animal diseases with climate and weather factors based on the available literature. Scope for research is vast in this new area and is discussed in a sub-head of the conclusion.

In the existing planetary system, life was established and growing over millions of years on earth. If we track down to the history of evolution, beginning with a living unicellular organisms Amoeba, growing to a gigantic size of Dinosaur and stabilizing at well adaptable stage of an Elephant in animal kingdom or to reach the present status of the intelligent human being, throughout these developmental stages the climatic/meteorological factors play a crucial and supportive role. Further the Development of plant/Animal kingdom is making rapid strides in tropical climatic zones where the temperature ambient ranges between 20⁰C to 40⁰C and the rain fall/humidity factors are moderate. We are fortunate enough that India is geographically located in tropical zone. This classic location advantage of the country in the world geographical map helped the country in keeping India as number one milk producer in the world, no 3 producer in poultry egg production, number 5 in horticulture production i.e fruits and vegetables. Climate change affects livestock both directly and indirectly. Direct effects from temperature, humidity, rainfall, wind speed and other climate factors, aggravates the heat stress in dairy animals, and influences animal performance badly: in growth factors, milk production in Dairy animals, mutton production/ wool production in case of sheep. egg and meat production in poultry, and reproductive aspects in all the species. The indirect impact of these factors on livestock may result on economic, nutritional and health aspects of human society and also its contribution to the economy of the country.

Sheep and goats in temperate regions are seasonal breeders with breeding activity mostly restricted to short day seasons of the year (Maule 1962). Endocrine mechanisms regulated by the variations of the day length stimulate reproductive activity to have maximum conceptions during the period of shorter days and correspondingly maximum births during longer day periods after a 5 months gestation (Hafez, 1987). Thus, essence of seasonal breeding is to ensure maximum births during the period congenial for survival of young ones, including availability of feeding materials and favorable climate. In tropical regions with minimum variation of day length and less distinct seasons, feed availability is not much affected by seasons in particular. Hence most species of animals maintains reproductive activity throughout the year (Devendra and Burns 1983). However there found to have influence of various locally relevant factors affecting comfort of living such as feed availability, weather and other environmental factors. Accordingly, there occur seasonal peaks and periods of restricted reproductive activity and pattern of the same can vary according to the local situations prevailing year to year (Goel and Agarwal, 1988 and Wani et al. 1980).

Demand of livestock products is on the rise in India. India?s demand forecast for milk, mutton, egg production is more than the current supply of these products. To meet this demand entrepreneurship initiatives are need of the hour .Further, younger generation of India seems more interested in commercial dairy farming rather than subsistence based farming. Therefore, entrepreneurial training to farmers is essential. An average entrepreneur faces several barriers to start a new enterprise. Some of them are as under

Setting up livestock enterprise be it a small dairy unit, goat unit, milk and meat processing plant, selling parlor requires capital. Lack of access to credit to expand the herd is a critical problem for farmers. There is little access to formal credit through the cooperatives or banks. Informal credit is available from private traders and agents of private companies, but the interest rate is very high. Keeping this situation in mind and to provide financial support from banks few major dairy entrepreneurship schemes have been developed and implemented by banks with the support of state animal husbandry departments across different parts of the country. National Bank on Agriculture and Rural Development (NABARD) is the lead bank for financial support of such schemes.

Expectations from Veterinarian as Extension Officer to Promote Entrepreneurship

The veterinarian has to act as facilitators to exchange experiences, share knowledge and information and participate in joint problem-solving. This requires linking farmers with the right support institutions and individuals who have expertise to deal with their specific concerns. Therefore, extension workers need to understand the training needs of the farmers and to identify the best trainers or training institutions to meet those needs. Part of this involves creating awareness about the training programme and explaining the objectives and content to potential trainees.

Extension workers should also assess the impact of the training on the behaviour of the participants and on the farm business Impact assessment is essential because it is the true indicator of the relevance and effectiveness of the training programme.

Extension workers can also provide more general support in the form of study visits, study tours. Farmers observe ?good entrepreneurial practices?, and learn from the practices of others. Farmers are taken on a tour. See markets first-hand, visit input suppliers and buyers, and make contacts. Farmers also visit farmers in other areas to exchange experiences and see new techniques. Such visits can transform a farmer?s view on production and marketing. Visits should be followed up with periodic evaluations to assess the impact of the visit and the use of new practices and techniques. They can also arrange seminars with possible topics like entrepreneurship, farm business management, market possibilities, successful case studies, new technologies, price assessments and market-oriented production techniques. Extension workers can also facilitate farmers working with producer organizations. Producer organizations can make useful contributions to developing entrepreneurship among farmers.

Project Appraisal : Assessing Project Benefits

Project appraisal helps to determine which among various projects one is to accept and which to reject. This is however possible only when costs and benefits have been identified, priced, and valued. A number of techniques of project appraisal can be discussed under two heads :

Abstract

The article briefly narrates the initiatives taken by the Department of Science and Technology, Govt. of India, New Delhi in providing solutions to rapidly growing Landslide Disasters in India. Duly considering the importance of the issue, the DST has embarked on a National Landslide Programme more than two decades ago and brought voluminous information on Landslide Vulnerability Mapping, Site Specific Landslide Investigations, Landslide Kinematics, Instrument Based Forewarning etc. by funding large number of research projects to various Academic/Research institutions in the country. In addition, the bilateral collaborative programme launched on Geohazards between India & Norway, resulted in bilateral flow of knowledge and capacity building amongst various tiers of the Academic, Research and the Planning Hierarchy, yielding tangible benefits.

INTRODUCTION

Landslides cause extensive damages to roads, bridges, human dwellings, agricultural lands, forests and other establishments year after year resulting in immense losses of life and properties. The entire Himalayan region has been the target of intense development activities for the last few decades. Hence the instabilities along the natural slopes are accentuated by the human activities since the development schemes are often not properly planned and implemented (Valdiya 1980; Thakur 2001). This has become the case in most of the mountains in India. Keeping in view of the stability of the slopes, the need of the hour is to achieve sustainable development of the hilly regions while implementing various developmental schemes. So there has to be a major S&T role to play to minimize the landslide problems. This should include all possible corrective and preventive measures to minimize the losses due to this disaster.

Abstract

The Rawana landslide, located in Sirmuar district of the Shimla Himalayas, Himachal Pradesh is repeatedly active in the recent years. It is a NE-SW oriented slide with the crown in the southwest and the wider toe in the northeast resting in Giri River. During some of the sliding events emanations of heat and gases were also inferred. In order to understand the landslide phenomenon and the causative factors, and there from to evolve mitigation measures, detailed studies of the slides were under taken. The Landslide hazard zonation mapping carried out in Rawana landslide using LHEF rating based BIS method indicates that it is located in high hazard zone. The detailed studies show the complex geological, structural, morphotectonic and hydrological setting. From the studies it is surmised that the toe erosion by Giri river and the rainfall infiltration in the mid slope region are responsible for the slide. Remedial measures have been accordingly evolved.

Abstract

The landslides that swallowed the whole of Malin village, Maharashtra on the early morning hours of 30 July, 2014 is one of the major disasters, next only to Kedarnath episode in the recent years. Consequently, the Department of Science and Technology, New Delhi, constituted an expert committee comprising the authors of the article which made a visit and took the on the spot assessment of the disaster. Their observations show that the area is covered by the Deccan basalts, which are layered with compact and vesicular basalts; fractured and jointed basalts due to tectonics and the cooling of the basalts; and have also undergone extensive geomorphic evolution. Due to such geologic/geomorphic setting, the flow layered basaltic hillock in which Malin is located is naturally benched, which is further being leveled for the agriculture purposes. The deforestation, leveling of the hills, excessive usage of water for irrigation and the lack of drainages outlet in such benched and leveled slopes have assigned high degree of landslide vulnerability to the area. Over this, when torrential rainfall occurred in the last week of July, the landslide was triggered. On the basis such inferences, some mitigation measures have been evolved after the visit.

2.1 Introduction

Farm ponds are the most commonly used source of ex-situ water harvesting structures. It has wide adaptability in farmers’ fields and used as handy source for water supply to crop fields. It has been used since time immemorial not only as an assured source of water supply to crops but also to meet demands in other sectors. However, these ponds have wide variations in shape and size as per the method of construction and their suitability for different topographic conditions. Most of the ponds, initially constructed in fields have regular shape. However, as time progresses and because of the poor or no repair and maintenance, these ponds loose their regular shape and become irregular.

12.1 Introduction

Farm ponds are used for multipurpose including as a viable source for supplemental irrigation to rainfed crops, a good place of entertainment, a vital place for wild life habitats, livestock and fish and aquatic plants. Like any other structure, the farm pond needs regular repair and maintenance for effective operation. The purpose of construction of the pond will be fruitful and the life span of the pond will be enhanced if proper care and maintenance are taken. In this chapter some salient discussions on care and maintenance of the pond are mentioned.

12.2 Maintenance Against Silting

The farm ponds constructed in medium to deep black soils are subjected to getting silted up. Hence, periodic desilting to restore the original storage capacity is required. If the pond is used for supplemental irrigation to crops, then desilting may be done once in every 5 to 10 years depending on the amount of silt getting deposited in the pond.

The breaches and rill formed in the spoil bank and shoulder bunds should be immediately repaired. The inlet and outlet structures should be maintained periodically. The silt deposited in the silt trap should be removed periodically. In areas where silt carried by the runoff is more, a vegetative filter near the inlet structure may be used. The pond may be desilted manually if it is small in size otherwise mechanical measures may be used to desilt. It is easy to desilt the pond when it is dry. A Simple and inexpensive method to desilt the pond is to stir the water of the pond and then allow the desilted water move away from the pond through the outlet (Belgaumi, et. al., 1997). Fig. 12.1shows a badly maintained pond with excess silting and weed infestation causing severe reduction of its storage capacity.

4.1 Soil Moisture Tension

Soil moisture tension is a measure of the tenacity with which water is retained in the soil and shows the force per unit area that must be exerted to remove water from soil. The tenacity is measured in terms of the potential energy of water in the soil measured, usually with respect to free water. It is usually expressed in atmospheres, the average air pressure at sea level. Other pressure units like cm of water or cm or mm of mercury are also often used (1 atmosphere = 1036 cm of water or 76.39 cm of mercury). It is also sometimes expressed in bars (1 bar = 106 dynes / cm² = 1023 cm of water column. 1 millibar = 1/1000- bar).

Soil moisture tension is brought about at the smaller dimensions by surface tension (capillarity) and at the higher dimensions by adhesion. Buckingham (1907) introduced the concept of ‘capillary potential’ to define the energy with which water is held by soil. This term, however, does not apply over the entire moisture range. In a wet soil, as long as there is a continuous column of water, it might be called ‘hydrostatic potential’, in the intermediate range the term ‘capillary potential’ is appropriate. In the dry range the term ‘hygroscopic potential’ would be suitable. However, the term ‘soil moisture potential’, ‘soil moisture suction’ and ‘soil moisture tension’ are often used synonymously to cover the entire range of moisture (Khonke, 1968).

10.1 Evapotranspiration (ET = Evaporation + Transpiration)

Evaporation is a diffusive process by which water from natural surfaces, such as free water surface, bare soil, from live or dead vegetation foliage (intercepted water, dewfall, guttation etc) is lost in the form of vapour to the atmosphere. It is one of the basic components of hydrologic cycle.

Likewise transpiration is a process by which water is lost in the form of vapour through plant surfaces, particularly leaves. In this process water is essentially absorbed by the plant roots due to water potential gradients and it moves upward through the stem and is ultimately lost into the atmosphere through numerous minute stomata in the plant leaves. It is basically an evaporation process. However, unlike evaporation from a water or soil surface, plant structure and stomatal behaviour operating in conjunction with the physical principles governing evaporation modify transpiration.

Thus, evapotranspiration is a combined loss of water from the soil (evaporation) and plant (transpiration) surfaces to the atmosphere through vaporization of liquid water, and is expressed in depth per unit time (for example mm/ day). Quantification of evapotranspiration is required in the context of many issues:

The term growth for bacteria and other microorganism usually refers to changes in the total population rather than an increase in size or mass of an individual organism. As the mechanism of conservation and dissipation of heat generated during metabolism lacks in bacteria, the enzyme system in bacteria gets directly influenced by temperature. The purpose of studying the bacterial growth curve is a) to become familiar with the population growth dynamics of bacterial culture and b) to plot a growth curve and determine the generation time of bacterial culture.

A number of methods are now available for measuring bacterial growth. Some important ones are

1)By colony counting or cell counting

2)By weighing the cells

3)By cell activity (turbidity method)

Antibiotics are produced by some true bacteria, actinomycetes and fungi that destroy or inhibit the growth of other microorganisms. Some antibiotics are synthesized or modified in the laboratory; however, their origins are always in living cells.

9.1 Assay of Antibiotics

Soil serves as the major repository of microorganisms some of which produces antibiotics. Four groups of soil microorganisms viz; Streptomyces, Bacillus, Penicillium and Cephalosporium represent three microbial types, namely, actinomycetes, true bacteria and molds respectively.

Following procedure may be applied to isolate antibiotic-producing microorganisms from soil:

Fermentation

The term fermentation is loosely used to denote any process in which microorganisms are involved, regards of whether or not the organism is growing in the presence of molecular oxygen. Thus, it can be defined as 'an ATP generating metabolic process in which organic compounds serve both as electron donor (becoming oxidized) and electron acceptor(becoming reduced). Energetically, fermentations are poor energy yielding process and products have lower energy content then the substrates. Since there is no net oxidation in fermentation, the number of molecules of C, H and O remain the same in products as in the substrate.

Abstract

An intellectual property infringement is the violation of an intellectual property right of the owner. Infringement is established based on the law governing appropriate IPR in the concerned country. Both civil and criminal remedies are available under the concerned law. The present paper introduces the patent infringement as per Indian Patent Act, 1970. It discusses various modes and types of infringements which can take place. It further discusses a procedure to formulate opinion about product infringing a granted patent. In the end some usual defenses against patent infringements have been discussed. Some case studies have also been presented along with the damages awarded for the patent infringement.

Abstract

The paper discusses patentability aspect of subject matter. Patentable subject matter must satisfy three basic criteria i.e. novelty, inventiveness and industrial applicability, though few subject matter satisfying all the three basic criteria stated above may still be not patentable in specific jurisdiction based on certain circumstances or as stated in the patent act of the specified jurisdiction. Therefore grant of a patent is subject to certain limitations mentioned in the section 3 and 4 of the Indian Patent Act for Indian jurisdiction. The aim of this paper is to study such limitations in detail.

World Intellectual Property Organization

http://www.wipo.int,http://www.wipo.org

The World Intellectual Property Organization - referred to in abbreviated form as WIPO in English, and OMPI in French and Spanish - was established by a convention signed at Stockholm on July 14, 1967, and entitled “Convention Establishing the World Intellectual Property Organization.” The WIPO Convention entered into force in 1970. WIPO became a specialized agency in the United Nations system of organizations in 1974 and dedicated to the use of intellectual property (patents, copyright, trademarks, designs, etc.) as a means of stimulating innovation and creativity.

WIPO promote the development and use of the international IP system through Services, Law, Infrastructure and Development.

According to Futter (2001) it is very important the way we cook our food. If the cooking is inadequate it causes food poisoning. While cooking there can be cross contamination starting from raw foods. It includes hands or utensils which can cause food poisoning. Most foods, especially meat, poultry, fish and eggs should be cooked thoroughly to kill most types of food poisoning bacteria. Generally the food should be cooked to a temperature of 75 °C or hotter. When food is cooked, it should be eaten promptly, kept hotter than 60 °C or cooled, covered and stored in the fridge or freezer. Some people are more at risk from food poisoning than others. In order to buy safe food in the market like buying pre-cut produce as a half a watermelon or cut veggies from a salad bar, it is important to choose items that are refrigerated or surrounded by ice. They must be kept in separate bags. FDA (2019) has studied the contamination in lettuce. Shopping at a farmer’s market is a great way to get locally-grown, fresh fruit, vegetables, and other foods. However, safety of these produce needs to be checked. Many markets have their own food safety rules and vendors must comply with them along with the government regulations. Fruits and vegetables must be washed thoroughly under running water just before eating, cutting or cooking. Fruits and vegetables must never be washed with soap or detergent or using commercial produce washes. Even if it has to be peeled before eating, it is still important to wash it first. Any bacteria present on the outside of items like melons can be transferred to the inside when it is cut or peeled. They should be refrigerated within two hours after preparation. The juice or cider must be treated (pasteurized) to kill harmful bacteria. Pregnant women, children, older adults and people with weak immune systems should drink only pasteurized or treated juice. Raw milk can harbor dangerous microorganisms like Salmonella, E. coli, and Listeria. World India (2017) has looked into the food regulations. These can pose serious health risks. Pregnant women, older adults and people with weakened immune systems are at higher risk for illness caused by Listeria. One source for these bacteria is soft cheese made from unpasteurized milk. It is vital to check the label to make sure that it is made from pasteurized or treated milk. Make sure that eggs are properly chilled at the market. FDA requires that untreated shell eggs must be stored and displayed at 45°F. While buying eggs it needs to be ensured that the eggs are clean and the shells are not cracked. Meat should be properly chilled even in the market and kept in closed coolers with adequate amounts of ice to maintain cool temperatures. If it is brought in an insulated bag or cooler during transit it is very beneficial to keep the quality. It should be always kept separately from your other purchases, so that the juices from raw meat (which may contain harmful bacteria) do not come in contact with produce and other foods. Essays (2018) have written a very comprehensive overview of food safety.

A process control system that identifies the hazardous points in the food production process is known as HACCP (Hazard Analysis Critical Control Point). It puts into place many stringent actions to prevent any hazards from occurring. In any food process if there is strict monitoring and controlling steps, the chances for hazards are minimum. Today, HACCP is an integral part of modern food industry that identifies and controls the major food risks. These are like microbiological, chemical and physical contaminants. These can also be practiced at home scale by checking proper storage, handling, cooking and cleaning procedures. These steps have resulted in industries taking greater responsibility for and controlling the food safety risk factors. This helps in better consumer protection, agriculture, the food processing industries and promotes domestic and international food trade.

The temperature of food storage is important. Below 4⁰C the food pathogens do not grow. Above 60⁰C some colonies begin to die. However, almost all die at 71⁰C. How hot is the food served is important for food safety. The size of the piece is important to how quickly it will cook all the way through. The smaller the piece the faster it will cook. Large or thicker pieces take a longer time to be cooked. Otherwise cooking for a longer time is better so that pathogenic microorganisms do not grow. In case of a thicker piece the color must be checked inside to outside after cooking which should be consistent. If the meat has the bone, check the color/temperature closest to the bone in the thickest part. In case of meat the contamination usually gets introduced while butchering and the practices used. The street food on a cart is perhaps the most contaminated as it has some level of bacteria in it. The meat in the decorated malls also has pathogenic bacteria. The environment plays a very pivotal role which can recontaminate the food even after proper cooking. The amount of harmful pathogens keeps growing in number with the passage of time. Fresh from the grill is the best, an hour or two is not ideal, half a day or overnight could make a person sick. Due to the reason that consumers do not know the time and temperature of cooking it is important to eat food which is freshly prepared.

4.1 Formulating Marketing Strategy for Agribusiness

STP – SEGMENTATION, TARGETING & POSITIONING

STP is the core concept which is followed while building a brand. A marketer decides a product which he is about to market first, and then goes about building a brand by deciding upon the specifications.

SEG MENTATION

Segmentation is process of dividing customers into a set of homogenous groups customers in general can be divided into groups based on geographic (or) location.

The below given chart like the major segmentation variable considered for consumer and industry market.

Agri Business Market Segmentation

The below given charts illustrates lists of segmentation variable that is customized for Agribusiness market. The following variable were suggested by the quarter Mr. Dute and were published in his base on principles of management in agribusiness segmentation based on physical attributes

An overwhelming proportion of plant material used for compounding herbal medicines and nutraceuticals is currently collected from the wild. With traditional health care systems gaining increasing popularity, the enormous amount of plant material extracted from the limited plant populations available in natural stands is a cause of justifiable alarm. The unscrupulous plunder of plant populations growing in the wild is pushing increasing number of important species to the endangered category and many to the verge of extinction. Also, unethical practices like adulteration and storage of medicinal plants under unacceptable conditions are rampant. All this is happening, when the consumer is becoming increasingly quality conscious and is demanding traceability of source material used for formulations and adherence to good practices for the entire chain of manufacturing process for herbal drugs and plant-based nutraceuticals. Clearly, solution to this problem lies in replacing the ‘collection from the wild’ paradigm to ‘production by cultivation’. An essential prerequisite for meeting this objective is a well thought out research agenda which not only tackles productivity enhancement goals for the targeted plant species but also addresses the validity of the entrenched notion among healers who use the traditional medical systems, that only material collected from the wild produces the desired results. The reason advanced in support of this argument is that phytomedicines are derived from plant populations growing in the wild under organic conditions and under their natural rhizosphere and rhizoplane. The associated soil-microbial complexes, and a variety of endophytic microorganisms, may be the initiators or modifiers of the production and expression of medicinal properties.

Objective: To estimate qualitatively various chlorophyll fractions

Materials Required: Leaf material, acetone, petroleum ether, distilled water, methyl alcohol, potassium hydroxide, diethyl ether, separating funnels, stand beakers and conical flasks.

Principle: In biological systems the molecule absorbing radiant energy in the visible range is referred as a pigment. To the human eye these pigments are coloured: chlorophyll is green, carotenoids are red or yellow, xanthophylls is yellow and phytochrone is blue. These pigments are complex molecules. Chlorophylls are the most important pigments active in photosynthesis. At least nine different types of chlorophylls are known – chlorophyll a, b, c, d, e bacteriochlorophylls a and b and chlorobium chlorophylls 650 and 660. Chl a and chl b are best known pigments. In addition to chlorophyll, carotenoids, xanthophylls etc. Are also present as accessory pigments. The chlorophylls are directly involved in photosynthetic electron transport the other pigments serve as accessory pigments and they also serve the purpose of light harvesting.

There are different organic molecules are soluble in different organic solutions, however, their solubility is differential in different chemicals. Based on the nature the chlorophyll pigments can be separated and identified.

Tissue culture refers to the collection of techniques used to maintain or grow of cells, tissues and organs under controlled environment. The German botanist G. Haberlandt (1854-1945) originated the concept of cell culture in which he described his pioneering experiments with isolated plants cells and developed a concept of totipotency (potential of a cell to reproduce entire plant and all of its characteristics). He is considered as father of tissue culture.

Growth and Development are the most fundamental and conspicuous characteristics of all living organisms. According to dictionary, growth is the advancement towards maturity and development is a gradual increase in size. The plant physiological definition of growth is ‘an irreversible increase in mass, weight or volume of a living organism, organ or cell.

Plants are exposed to various stresses such as temperature, water, oxygen, salts, nutrition etc, during its growth under dry land condition. Various simple tests have been developed by plant scientist for evaluation of different cultivars against these stresses. These tests are simple to perform in the laboratory with fewer instruments that are commonly available in most of the laboratories in developing countries. These tests have significance in plant water relations and cultivars reliably screened for various stresses. The crops upon which these tests have been performed here are used by the proponents of the tests. These tests are not advised to be performed on crops other than those used by the authors. It probably needs standardization for other crops. The following test has been explained for the benefit of the readers.

The effects of global warming and/or climate change are of concern both for the environment and human life. Evidence of observed climate change includes the instrumental temperature record, rising sea levels, and decreased snow cover in the Northern Hemisphere. According to the IntergovernmentalPanel for Climate Change (IPCC) Fourth Assessment Report, “most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in [human greenhousegas] concentrations. It is predicted that futureclimate changes will include further globalwarming (i.e., an upward trendin global mean temperature), sea level rise, and a probable increase in the frequency of some extreme weather events. Ecosystems are seen as being particularly vulnerable to climate change. Human systems are seen as being variable in their capacity toadapt to future climate change. To reduce the risk of large changes in future climate, many countries have implemented policies designed to reducetheir emissions of greenhouse gas.

ABSTRACT

Using a hand auger of 2 m length, upper, middle and lower core sediment samples of seventy nine in number have been collected from the Vaippar river, its tributaries and Vaippar beach in order to understand the role of Vaippar river and its tributaries in making up the Vaippar beach placer deposits. The heavies are found to be concentrated abundantly in fine and very fine size grades of all the samples collected from both the environments. The average heavy mineral concentration varies from 3.13 to 17.40 % in river bed while it is 6.19 – 64.82 % in the beach. In river bed, the pattern of concentration of heavies in upper, middle and lower core samples does not show any characteristic uniform pattern and inferred that it is controlled by the grain size of the parent rock, supply of sediments from the source, geomorphological features of the river and hydrological characters of running water. In the beach, the concentration of heavies are effected mainly due to the winnowing action of waves. However, a phenomenal increase in the heavy mineral concentration of beach samples might be due to the supply of sediments from other source besides the Vaippar river.

ABSTRACT

Mapping and exploration of iron ore deposits in parts of Salem District is carried out based on the detailed field work and the interpretations of IRS-1C PAN data in the scale of 1:12,500 and aerial photographs (NRSA, Scale 1:4,000). The study results that the major rock types of the study area are banded magnetite quartzite, garnetiferous pyroxene granulite, amphibolite, garnetiferous pyroxenite, charnokite, talc tremolite, actionalite and dunite rocks. The Banded Magnetite Quartzite’s (BMQ) occur as enclaves within the hornblende gneisses at several parts of the study area. Topographically, the rocks constitute small low-lying linear ridges at some places it is found to be closely associated with garnet pyroxene granulites. A remarkable feature about the mode of occurrence of magnetite quartzite is its linear nature and the physical form, which could be described as a “Band”. All the bands possess an ENE-WSW strike and the dip is found to be steep (above 70 degrees) towards north. The rock in the hills of Godumalai, Vellalagundam, and Singipuram are highly deformed and contact with garnetiferous pyroxene granulite and hornblende gneisses. In hand specimen, the magnetite quartzite rock exhibits fine banding. In general no variation in grain size or thickness of banding could be seen megascopically. However, occasional increase in size of magnetite might be possible as seen from the coarser magnetite pebbles strewn in the channels of the area. There are two types of folds observed namely F1 and F2. The axial plane trace of the F1 varies in trend from WNW-ESE to WSW – ENE. The joints are traced in the directions of NNW-SSE to NNE – SSW and WNW – ESE to ENE-WSW. The interpretation of lineaments shows their trend directions of NNE-SSW, NE-SWand NNW-SSE. The above said work has carried out through detailed field work and interpretations using by IRS-1C PAN data in the scale of 1:12,500 and aerial photographs of NRSA, in the scale of 1:4,000 for the study area.

ABSTRACT

The upper Agniar and Vellar river basins principally consist of three major rock typesnamely pink granite, gneiss and charnockite. The major geochemical pattern of these igneous rocks when studied indicate that charnockites have a trend of low Mg2+ and high Ca2+ + Na O to high K+ end, whereas the same is vice – versa for hornblende biotite gneiss and also for granite gneiss. The pink granite has an intermediate trend between the charnockite and hornblende biotite gneiss. The value of SiO2 in all the rock types was found to increase with the increase of K2O, Na2O and Al2O3. Further, a decrease in the values of MgO, Fe2O3, TiO2 and CaO was noticed with an increase in SiO2. On the basis of the distribution pattern of these elements, the origin of the igneous suites in the above two basins was inferred.

ABSTRACT

The disposal of industrial effluents in rivers causes groundwater contamination. It is necessary to assess how these contaminants are likely to migrate in the groundwater system. In the present study, an attempt is made to study the migration of contaminants in the groundwater of Palar River basin in Tamil Nadu. Simulation of the contaminants was carried out by using numerical methods. The finite difference computer code MODFLOW (Modular 3-d finite difference flow) and MT3D (Mass transport 3-d) with Groundwater Modelling System (GMS) as pre and post processor was used to simulate the groundwater flow and transport in this study. The simulation was done in transient state for a time period of one year. It predicted the migration of plume of chlorides in groundwater. The changes in the distance and concentration rate of chlorides are identified for a particular period. Modelling provides a useful basis for contaminant transport studies, as well as in the evaluation of the hydrogeologic parameters relevant in the context of the transport problem.

ABSTRACT

Trace Elements were analysed from water samples collected from bore wells from block 2, 5, 14, 26 and 29 at Neyveli Township. Lead Concentration has crossed the limit of ISI standard prescribed for drinking which is 0.100 ppm. Lead concentration in the order of 0.082 ppm at block 5 and 0.11 ppm in block 29 were observed. Cadmium concentration has also crossed the limit of ISI (0.010 ppm) for drinking purpose, which is 0.02 ppm in block 26. Chromium concentration has also crossed the permissible limit of ISI standards (0.05 ppm) for drinking, which is 0.098 ppm in Block 14.

The above elements when compared with ISI standards for drinking water have shown a slight increase in concentration of lead, cadmium & chromium. Concentration of lead in Neyveli basin may be attributed to basement geochemical sources influenced by physical and chemical weathering. High concentration of chromium and cadmium in the aquifer may be due to anthropogenic activity probably from effluents of closed briqueting & carbonization plant, which is due south of block 14.

ABSTRACT

The study narrates the importance of occurrence of groundwater in the crystalline terrain and its yield in different lithologies. In general, yield of well in the crystalline terrain of the study area is low. Average or mean yields for groups of wells in various regions are most commonly between 7 to 20 gpm: The smallest yields are encountered in granulitic terrain and this may be due to fracture closing rapidly with depth. The jointed and weathered geneses yield small but steady supply of water at shallow depth. Chemical quality of the groundwater from this terrain is generally satisfactory for most purposes.

ABSTRACT

The chemical characteristics of the groundwater in and around the Valapadi taluk of Salem district have been studied to evaluate the suitability of water for domestic and irrigation uses. Twenty three groundwater samples representing the shallow and deep aquifer of the area were collected and analyzed for pH, TDS, Ca, Mg, Na, K, HCO3, CO3, SO4 and Cl. It is observed that the quality of the groundwater is suitable for domestic use with some exception. The observed high quantity of Cl, SO4 and Mg at some places require immediate attention and detailed study. The value of EC and SAR indicate good to medium q of water for irrigation.

ABSTRACT

Hydrogeochemistry of a region is a reflection of hydrodynamic process, composition of lithology and physical constraints. The water chemistry is the resultant of all biogeochemical processes and reactions, which have acted on water from the moment it has condensed in atmosphere till the time it is discharged. A case study has been carried out in a varied lithological terrain with Archean, Alluvium and Tertiary rocks to unravel the hydrogeochemical process. A geochemical model relays the distribution of mineral species in the groundwater. Geochemical modeling WATEQ4F has been carried out for pre-monsoon and monsoon period of various litho units in Gadilam river basin, Tamilnadu to find out the disequilibrium indices of carbonate (calcite, dolomite, magnesite and aragonite) and sulfate minerals (anhydrite and gypsum). The result of the model reveals that carbonate minerals show the over saturation state in monsoon period and the Sulfate minerals exhibit under saturation state in both the seasons.

ABSTRACT

The sources of fluoride in groundwater are minerals like fluorite, apatite, mica, amphiboles,cryolite and fluor.spar. The undue concentration of fluoride greater than 1 mg/l has befallen a major toxicological and geoenvironmental issue in India. Excess of fluoride in groundwater causes skeletal and dental fluorisis. The study area forms part of Salem district with records of endemic fluorisis. To decipher process and chemistry of fluoride, a total of 46 groundwater samples were collected from major litho units of the study area (Peninsular gneiss and Charnockite) and analyzed for fluoride using standard procedures for two seasons viz. pre and post monsoon. In pre-monsoon, maximum and minimum fluoride in Peninsular gneiss and charnockite were ranging from 2.85 to 0.4 mg/l and 4.02 to 0.37 mg/l respectively. The coresspnding figures in post monsoon ranges from 2.84 to 0.32 mg/l and 1.91to 0.37 mg/l respectively. Higher concentration was noted in charnockite folowed by peninsular gneiss in pre monsoon and the effect of dilution was well noted in post monsoon season. Statistical analysis undercovers the relationship of fluoride minerals with other ions. Modeling results represent the leaching of fluoride minerals and their variation along with seasons.

ABSTRACT

The present work relates to geological and commercial aspects of pyroxene syenite (Green Onyx) occuring in and around Sivamalai of Periyar District in Tamil Nadu. The alkaline complex of Sivamalai comprises syenites-, nepheline syenite and their variants. Pyroxene syenite is possibly the oldest within the syenite complex occurring as minor massifs, elongated linear bodies, -arcuate islands and enclaves within feldspar syenite are observed in the hillocks North East of Sivamalai, namely Chennimalai and its southern extensions. On the commercial point of view, the pyroxene syenite in the study area occupies nearly 30 square -kilometres area and can be categorised as Kalleri Block, Neykkarampalayam Block and Sivamalai Block. The observed petrographic and petrochemical characters of the alkaline rocks of the study area favours magmatic origin for these rocks. A detailed geological study and random market survey of individual syenite bodies proved the true worthiness of the material Green-Onyx as a dimensional stone with substantial resources and market potential.

Packaging is a tool that is used to contain the product, protect the product from environmental hazards and help in marketing the product. Examples of ideal natural packaging systems are that of a banana, orange, coconut and egg, where the packaging is provided by nature. The major step forward in the food processing arena has been the ability to protect and preserve products with packaging and hence ensuring the availability of fresh and processed products out of season and over long distances in various forms. Milk is a highly perishable product and is not uniformly available round the year to the whole country due to geographical and genetic variations. If dairy products are to be available all the year round the country, irrespective of the season and area, it must be presented in packages that are convenient to purchase and use.

Packaging has additional responsibilities of providing convenience, safety and facilitating, besides handling, storage and distribution of products. It should prevent spoilage of food by microbial or insect attack. It also preserves the quality and nutritive value of many foods by the exclusion of oxygen and the control of moisture loss or gain. It increases the shelf-life and ensures longer availability and contributes to the product image through structural and graphic design. Product information is also given out through the medium of labeling, which acts as a tool for marketing and advertising.

Insects, belonging to the phyllum-arthropoda, have an open circulatory system. An open circulatory system is that in which blood bathes the organs rather internal organs directly in the haemocoel, the coelom of the insects, which actually is not a true coelom. Almost entire haemocoel of insects is formed from the epineural sinus. The haemocoel is divided into the perineural sinus and perivisceral sinus by the dorsal and ventral diaphragm respectively. The characteristic of insects is the presence of dorsal vessel, which comprises of anterior aorta and a posterior heart and is the only conducting tube present in insects. The blood of insects mostly does not perform gaseous exchange, therefore it does not contain haemoglobin, and blood in insects is called the haemolymph, which is red-coloured. So in order to study the circulatory system of insects, the major focus must be on the dorsal vessel, which has been described as follows, along with its accessory structures.

The respiratory system or tracheal system is involved in gaseous exchange in the insect with the environment. In this system there is a system of internal tubes, the tracheae that directly transport the oxygen to the parts of the body. Therefore, it does not use the circulatory system as the vehicle for gaseous exchange. The trachae open outside through segmental pores called spiracles having some system of closing and opening. Except proturans and some collembolans all insects possess tracheal system for respiration. These insects live in moist habitats where gaseous exchange takes place directly with the environment via the integument.

Exocrine Glands Types: Exocrine glands are generally of ectodermal origin and are widely scattered over the insect. Exocrine glands release their secreations through ducts into the lumen of various internal organs. Example: Accessory reproductive glands, salivary gland, silk gland. Gland is mainly composed of secretory epithelial cells. These are simple unicellular, bicellular, multicellular, complex multicellular (compound glands). These glands are ectodermal in origin and are secreated over the insect body.

Examples. Wax glands, lac glands, cephalic glands, poison glands.

1. Glands pouring (secreting structural materials). Some insects secrete substances that are used in building their houses (beehive) as protecting them (lac or cocoon).

Agriculture is very intensely influenced by weather and climate. While farmers are often compliant in managing weather and annual variability, there is however a high degree of adaptation to the local climate. This may be in the form of conventional infrastructure, native agricultural practices or personal experience. Climate change an in this way be relied upon to affect the agriculture, possibly threatening established characteristics of farming systems and provide chances for improvements. The role of climate change in influencing human activities and the natural environment is all around acknowledged. This may go from an extreme event enduring just a couple of hours (i.e. hurricane, thunderstorm and showers) through to the multi-year dry spells (Maracchi et al., 2005). Increase in concentration of greenhouse gases in the atmosphere further contribute to climate change. This results in a strong impact on human activities and natural environments. Essential areas, for example agriculture and forestry, will be more susceptible than auxiliary and tertiary segments, for example manufacturing and retailing (Parry et al., 1998). Agriculture is the fundamental activity by which people live and survive on the earth. Evaluating the impacts of climate change on agriculture is a vital job. In developed as well as developing nations, the influence of climate on crops and domesticated animals regardless of water system, enhanced plant and creature cross breeds and the developing utilization of synthetic manures. The continuous dependency of agricultural production on light, heat, water and other climatic factors, the reliance of a great part of the total populace on farming exercises, and the noteworthy extent and quick rates of conceivable atmosphere changes all consolidate to make the requirement for an exhaustive thought of the potential effects of atmosphere on worldwide agriculture (Rosenzweig, and Liverman, 1992).
