Introduction

The tropical root and tuber crops are comprised of crops covering several genera. They are staple foods in many parts of the tropics, being the source of most of the daily carbohydrate intake for large populations. These carbohydrates are mostly starches found in storage organs, which may be enlarged roots, corms, rhizomes, or tubers. Many root and tuber crops are grown as traditional foods or are adapted to unique ecosystems and are of little importance to world food production. Others such as cassava (Manihot esculenta Crantz) and white-fleshed sweet potato (Ipomoea batatas L.) are known worldwide. Several of these crops have been termed under-exploited and deserving of considerably more research input

Potato and Banana chips: Potato chips are one of the popular snack foods consumed throughout the country. Chips are mostly prepared by small scale artisans / confectioners, and sold in plastic film or paper packs. Recently, however some of the companies have installed plants having relatively large capacities and have started marketing chips in attractive packs. The fat content generally ranges between 25-40% and moisture content between 2-4%. Potatoes having high total solids, low reducing sugars and low amylase activity are most suitable for chips manufacture.

Banana chips are prepared from varieties rich in starch having very low levels of soluble sugars and polyphenol - oxidase activity. These are mostly processed and marketed in Southern States especially in Kerala. Previously, the chips were fried in coconut oil, but now other vegetable oils are also used in their processing. Relatively, banana chips are harder in texture than potato chips.

Introduction

In terms of individual health and physical condition, the situation in modern society is rather giving rise to concern. The last decades have seen a tremendous increase in availability and variety of food products which has undoubtedly affected the food habits of the average individual. Despite the fact that food has become overall safer and increased accessibility allows for healthier diets, worrying we are nevertheless faced nowadays with diet- related diseases of proper epidemic proportions. We now encounter an epidemic of obesity that spreads not only to the majority of the adult population but also, more worryingly, to young people who have rarely the option of alternative diets. Moreover, as scientific proofs for the link between diet and disease (particularly cardiovascular diseases and some cancers) accumulate, action is urgently needed. There are an increasing number of calls for action. It is within this situation that functional foods have developed. They assume a highly targeted solution to the diet related diseases with effective reduction of risk and improved physical and mental well being. That represents a big step from the traditional food-for-nutrition but the scientific milieu is ready to take the chances. The emerging ‘functional food science’ is focusing research on the effects of functional foods on growth, development, metabolism, the cardiovascular system, intestinal physiology, and even on behavioural and psychological functions (FAIR, 2000, Vol. 1). In view of these facts, it should appear necessary to assess and evaluate the developments in food production in terms of their effect on the individual consumer and the society at large.

The relationship between man and plant resources of his surroundings is intimate. Of the 350 tribes inhabiting different parts of India, about 171 dwell in Himalayan region. The inhabitants of the mountain areas use native flora for food, fodder, fiber, fuel, timber and for health care of both human beings and their livestock. These plant resources, particularly medicinal and aromatic plants (MAPs), not only meet their health care needs but also support their livelihood. Recently the demand of MAPs has transformed from local and traditional needs to global needs. This has adversely affected availability and quality of raw material as also livelihood and health options of the local people. Most of the raw materials are gathered from the forests, and only a few plants are under cultivation. To avoid rampant exploitation of MAPs from nature, there is an urgent need to establish procedures for their cultivation and organized marketing. The present article deals with strategies and actions to protect livelihood options of the indigenous communities inhabiting mountain areas in western Himalaya as well as promote sustainable utilization of MAPs through scientific and technological interventions.

Introduction

India and China are two major Medicinal and Aromatic Plants (MAPs) producing countries, providing 40% of the global diversity and availability of rare species. The Ministry of Environment and Forests, Government of India has identified and documented over 9,000 species of medicinal plants that are significant for the pharmaceutical industry (AICRPE 1996). Of these, 2,000 to 2,300 species are used in traditional medicines while at least 150 species are used commercially on a large scale (EXIM Bank 1997).

Seed processing, drying, cleaning and upgrading

Seed processing refers to all the steps necessary for preparation of harvested seed for marketing namely handling, drying, shelling, preconditioning, cleaning, size grading testing, and packaging etc.

Layout for seed processing plant

Layout plan for construction of seed processing plant should be carefully planned to ensure that thorough seed cleaning, upgrading, seed treatment and other seed processing operations are carried out efficiently without mixing and damaging seed lots with minimum equipment, personnel, time and at minimum cost.

The following factors should be considered while planning and designing the processing unit:

• Database
• Data Model
• Database Software
• DBMS Facility 
• Architecture for a DBMS
• Data Modeling
• Components of a Data Mode
• RDBMS (Relational Database Management System)
• Client/Server Model of Computing
• Entity Relationship Diagram (E-R diagram)
• Entity Relationship Diagram Notations - Front-end and Back-end
• Codd’s Rules
• SQL - Structured Query Language
• Data Definition Language (DDL)
• Data Manipulation Language (DML)
• DCL
• Data Control Language
• Transaction Control (TCL)

Evolution is a self-occurring natural phenomenon by which new organisms develop gradually as a result of change in genetic pool of a population. It is a very widely and historically studied phenomenon which still surprises scientists due to its underlying complexity. The three processes which contribute most to evolution are genetic drift (also known as random drift or allelic drift), natural selection and mutations. Genetic drift and natural selection act at a population level, whereas mutations act at individual level. For evolution to occur, the changes these processes bring about must be heritable, which they are.
 
Genes are present on chromosomes inside nucleus of the cell and the collection of all the genes in a cell is known as the genome of that cell. Genome size and complexity varies from species to species. Simple organisms, such as bacteria and protozoans have a very simple genome, with very few genes, whereas complex higher organisms such as humans have a large genome, with thousands of genes. The position of a gene on a chromosome is known as a locus. Organisms may have more than one copy of a chromosome in the cell.

INTRODUCTION

The propagation of plants has been one of the fundamental occupations of mankind since beginning of civilization. Plant propagation involves the application of specific biological principles and concepts in the multiplication of plants for useful purposes. The present day plant propagation industry is large and complex and involves not only the group that multiplies the plants for sale and distribution, but also a large group of industries that provide services, sell the product, is involved in regulation, provides consultation carries on research or is involved in teaching. The key person with in this complex, however, is the plant propagator who possesses the knowledge and skill either to perform or to supervise the essential propagation tasks for specific plants.

INTRODUCTION

Custard apple (Annona squamosa L.) is considered as one of the delicious fruit meant for table purpose. In India, during the year 2014-15 the area under cultivation of custard apple was 29870 ha with production of 228370 tones and productivity of 7.65 tones ha-1 (Anon, 2015a). In Maharashtra, the area increased by 9 to 10 times recently i.e. since 1990 onward, after start of Economic Guarantee Scheme (EGS) of Government of Maharashtra. Hence, Maharashtra is the leading state in custard apple production, wherein during the year 2014-15, the area, production and productivity of custard apple was 8660 ha, 59330 tones and 6.85 tones, respectively. This accounts about 25.98 per cent share of the state in the national production. This is followed by Gujarat, Chattisgarh, Madhya Pradesh and Karnataka. (Anon, 2015a). The largest area of nearly one third of the Maharashtra State is in Purandar tahsil of Pune district. An average production of custard apple in Purandar area is about six tons ha–1. The farmers fetch high economic returns at very low input cost. Besides, export quality fruits get very high price ranging from Rs. 70 to 800 kg-1 (Anon, 1998) in foreign countries.

INTRODUCTION

Persian walnut (Juglans regia L.) is of great importance across worldwide where nuts are harvested from wild stands, backyard gardens and rarely from commercial orchards that vary considerably in their size and degree of management. Nuts are collected for home consumption, sale at local roadside stands and markets and for shipping to cities. Walnut trees are further utilized for their high quality timber to make a wide array of products. The leaves, bark and other plant parts are used for medicinal remedies and trees are grown and maintained for soil conservation purposes (Mamadjanov, 2006b). A diverse mix of seedlings, local selections, and advanced cultivars are grown for nut production, many with unknown origins, including some of which are the direct result of selection from the wild.

Key facts
    
•    Dioxins are the most dangerous and ‘super toxic’ chemicals so far known on the earth and three closely related families are collectively known as dioxins. These are Polychlorinated dibenzo-p-dioxin or dioxins (PCDDs), Polychlorinated dibenzofurans or furans (PCDFs) and polychlorinated biphenyls (PCBs).
    
•    2, 3, 7, 8-TCDD (or called TCDD) is the most potent of all the congeners. The toxicity equivalency factor or TEF of TCDD has been assigned as 1, while all other congeners assigned in order of toxicity ranking magnitude relative to TCDD.
    
•    There are 75 compounds/congeners in the dioxin family (PCDD), 135 compounds in the furan family (PCDF) and 209 possible compounds in the PCBs based on the possible number of chlorine atoms.
    
•    The toxicity of dioxins and dioxin-like compounds vary substantially among the different PCDDs, PCDFs and PCBs. It is generally accepted that only 29 out of the 419 congeners of dibenzo-p-dioxins, dibenzofurans and polychlorinated biphenyls are toxic to humans and other organisms. The TCDD is most toxic and registered by the WHO as carcinogenic for humans.

Abstract

We studied the mathematic model of “predator-prey” and„ pest-parasite”. Under the circumstances when these two specious coexist in particular conditions. In that case the components of the system continuously change. We describe the system by two differential equations which conclude into numeral equation by integrators and variables. According these equations we calculate some numeral formulations essential to these changeable populations.
  
We produce the prevalence of predator-prey systems by using analytic and quantitatic methods for massive rage of data. This process as usual is described by the differential equation consisting assembling point. The constructed phase portrait which we need to solve the problem is found by Runge-Kuta method. So the article speaks about the conformity with a law which we receive by permanent change of parameters’ menaings and temporal changes of biological systems’ conditions.

When there is no positive steady state both prey and predator can become extinct. In one particular case both species become extinct regardless on the initial data. In the second, both species will die out only if initial prey/predator ratio is too low. Otherwise, only the predator goes extinct, while prey tends to carrying capacity.

Participatory technology development (PTD) is an approach to learning and innovation that is used in international development as part of projects and programmes relating to sustainable agriculture. The approach involves collaboration between researchers and farmers in the analysis of agricultural problems and testing of alternative farming practices.

Origins of participatory technology development

The origins of Participatory Technology Development can be found in a number of approaches, concepts and techniques that became popular in the 1970s and 1980s:

Farming systems research and extension, an approach that introduced social-ecomomic issues into organisations previously dominated by biological and chemical scientists. FSR/E also promoted the idea on ‘on-farm’ trials:

Appropriate technology, a concept that recognises the importance of matching the design of technology to the resources and culture of the user.

Meaning, Concept & Definition of Education

1. “Education is the process of developing capabilities of the individuals so that they can adequately respond to their situations”.

2. The modern definition of Education- “It is the production of desirable changes in human behavior- in knowledge (things known), attitudes (things felt) and skills (things done), in all of them or in one or more of them”.

3. Education is the process of giving training and instruction to people to develop their knowledge, abilities, skills, character and mental powers.

Knowledge: It includes-facts, concepts, principles and relationship.

For example: Extension worker educates a farmer on cultivation practices in sweet corn. (Things known)

Attitude: An attitude can be loosely defined as a feeling towards some object, person, and situation or idea. For Example

Extension worker changes the negative attitude of a women farmer and makes them adopt Mushroom cultivation. (things felt)

Skills: Ability to do things.

For example: Extension worker improves skills of a cotton farmer on stem application of pesticide (things done)

Carbon assimilation or carbon fixation is the conversion of inorganic carbon (carbon dioxide) to organic compounds by living organisms. The most prominent example is photosynthesis, although chemosynthesis is another form of carbon fixation that can take place in the absence of sunlight. Organisms that grow by fixing carbon are called autotrophs. Autotrophs include photoautotrophs, which synthesize organic compounds using the energy of sunlight, and lithoautotrophs, which synthesize organic compounds using the energy of inorganic oxidation. Heterotrophs are organisms that grow using the carbon fixed by autotrophs. The organic compounds are used by heterotrophs to produce energy and to build body structures. “Fixed carbon”, “reduced carbon”, and “organic carbon” are equivalent terms for various organic compounds.

CONTRACEPTION DUE TO MISALLIANCE AND TERMINATION OF PREGNANCY IN BITCHES

It is obvious that breeders maintain varieties of breeds but mismating do occur within their own premises and sometimes by unwarranted stray animal.

Misalliance complicates too many other problems.

Incidence of mismating is 15 to 20 percent in canine breeding.

Q.1 A random variable (r.v) is a real number x connected with the outcomes of a random experiment.

Q.2 In tossing of a balanced die at one time, the number coming on the upper most face of the die is a random variable x which takes any one out of 6 values taken as 1, 2, 3, 4, 5, 6.

Q.3 Let s be the sample space associated with a given random experiment. A real valued function defned on s and taking values in R (-∞,∞) is called one dimensional random variable.

Q.4 In general a n dimensional random variable is simply a function whose domain is S and whose range is a collection of n-tuples of real members (vectors in n-space).

Access to information and improved communication is a crucial requirement for sustainable agricultural development. Modern communication technologies when applied to conditions in rural areas can help improve communication, increase participation, disseminate information and share knowledge and skills. It is being said that “Cyber Extension” would be the major form of technology dissemination in the near future. However it is observed that the rural population still have difficulty in accessing crucial information in order to make timely decisions. It is essential that information availability is demand driven rather than supply driven. The challenge is not only to improve the accessibility of communication technology to the rural population but also to improve its relevance to local development.

The advent of INTERNET on communication scenario offers enormous potential for two-way on-line communication between distant parties via the telecommunication and computer network spread over the entire globe. The world is rapidly shrinking to a ‘global village’ which some courageously even call a ‘global family’. The merger of communication (audio and video) and computer technology has suddenly made this combination so powerful that no sector of human activity can afford to ignore it. Right from high security defense systems, space research, engineering and educational applications the INTERNET has found users in petty shopkeepers and small service agencies. In countries like Singapore, you can book a taxi via e-mail and the concerned taxi driver is able to confirm your booking, while he is still driving.

Introduction

Over the last two decades the Land and Water Development Division (AGL) has been at the forefront of the development and application of computer-based systems to analyse data and generate information to support decisions on various land and water issues . Separate soil and land and water systems have been developed. The soil and land systems focus on methodologies and tools for the assessment of land resources potentials at global, regional and national and sub-national levels. The water systems concern irrigation water use and management at field level and water resources assessment at regional and national levels.

AGL has been cooperating with various units within FAO and numerous international agencies and national institutions in developing and applying the systems.

Initially, in the late seventies and early eighties, the systems were developed for mainframe and mini-computers. From the late eighties they were gradually adapted to microcomputers. At the same time computer tools for managing spatial data, including geographic information systems (GIS), remote sensing and global positioning systems (GPS) were introduced. Since the last few years the availability of networked PC workstations, rapid application development environment and multimedia tools have opened an era of completely new possibilities in the development and application of the systems.

Origin and Domestication of Sheep

The domesticated sheep belongs to phylum-Chordata, class-Mammalia, order- Artiodactyla, family - Bovidae, sub-family - Caprinae, genus - Ovis and species- aries. They are hollow horned, cloven-hoofed ruminants of relatively smaller size. Sheep plays an important role in Indian agrarian economy as it is having multi facet utilities like meat, wool, skin, manure and to some extent milk and transport also. Marginal and sub-marginal lands of arid and semi-arid tropics are well adapted by sheep. Among the different wild species, Asiatic (Ovis orientalis) species of mouflon is considered to be the ancestor of present day sheep. Sheep were domesticated by man at around 9000 BC. The reference of role of sheep in the economy of mankind is found in the history of civilization of Mesopotamia, Mohen-jo-Daro and Harappa in Northern India.

6.1 Introduction

There are a variety of intrinsic and extrinsic fiber-optic sensors which use absorption spectroscopy indirectly for the detection of various chemical species. These include pH, metal ions, oxygen in water etc. In such sensors a suitable reagent is immobilized on a solid support. The support can be the core of the fiber or some optical material attached at the end of the fiber. Further it is optically transparent to allow transmission of the light signal from the interface and should remain inert to the chemical reaction being analyzed. The analyte (or the chemical species) when comes in contact of the reagent affects the absorption properties of the reagent. In other words, in these sensors, the reagent acts as a chemical transducer for analytes that are not directly measurable by optical techniques. Following conditions for the use of reagents in sensors must be met:

7.1 Introduction

There are numerous wavelength dependent phenomena that may be used to modulate the wavelength of incident light source. These are wavelength dependent absorption, luminescence, dispersion, interference and scattering. Wavelength modulated sensors use a broadband source, a wavelength modulator or measurand (i.e. analyte), a form of spectrometer (using prisms, gratings or interference filters), a detector (single photodiode or array) and signal processing unit. Silicon photodiode is cheap and can be used for detection but it limits the detection wavelengths to the region 400 to 1050 nm. The sensitivity or the resolution of the wavelength modulated sensor depends on the characteristics of the detector, the inherent resolution of the spectrometer, mechanical stability of the modulation unit and the spectrometer, and the capability of the signal processing unit. However, wavelength modulated sensors do not require any form of referencing like intensity modulated sensors. In intensity modulated sensors, loss in intensity occurs due to connectors and splices, microbending, mechanical creep and misalignment of light sources and detectors due to environmental effect. Further the fluctuations in light source can affect the performance of the sensor. Thus, for intensity modulated sensors one needs referencing to cancel out these losses. In some intensity modulated sensors two wavelengths are used. One wavelength is used to cancel out all of the losses while the second is used to sense the measurand.

Wavelength detection is relatively easy if the spectral changes result from changes in chemical indicator dyes, fluorescence, phosphorescence, or black-body radiation. In these cases the incident and emitted wavelengths are far apart and therefore detection is easy. If the spectral change occurs due to mechanical movement, then the wavelength filtering mechanisms must have sufficient resolvable spectral points. The reasons for using fluorescence in the fiber optic sensors are well known. Fluorescence is intrinsically more sensitive than absorbance and is more flexible in that a great variety of analytes and physical parameters are known to change the emission of particular fluorophores. The fluorescence based sensors utilize the change in the intensity, lifetime or colour of fluorescence as the affected parameter by the measurand. That means, any interpretable observation of fluorescence can be made the basis of a sensor. In this chapter we shall first describe luminescence phenomenon and then various physical and chemical fiber optic sensors based on wavelength modulation and fluorescence phenomenon.

Abstract

Though India is second largest producer of fruits and vegetables but is far behind in per capita availability of this protective food as compared to many developed countries. Floriculture and allied horticulture crop production (spices, medicinal & aromatic crops, mushroom etc.) have great potential to generate high income, jobs and new careers. Hi-tech horticulture is the need of all the developing countries and it refers to “the precise production techniques for efficient use of inputs at appropriate time and quantity for maximization of yield and quality of crops”. Various ways to make horticulture hi-tech include modern nursery management including micro propagation, protected crop production, high density planting including canopy management, use of agrochemicals, rejuvenation technique, interated nutrient management, integrated water management, integrated pest and disease management. Inspite of this, in present context, major emphasis has been given on clean horticulture production with bio-derived, renewable energy sources for developing a profitable CEA (controlled environment agriculture) that would help in sustaining the system, improving socio-economic status of growers and of-course environment-friendly.

6.1 Introduction

The food industry produces large volumes of waste both solid and liquid, starting from the initial step of raw material to the final consumption of processed food. Apart from a loss of valuable biomass and nutrients, the generated waste poses increased disposal and potentially severe pollution problems. Meat and meat industry is no exception where slaughter houses, meat processors, wholesalers and rendering plant generates huge amount of waste [1, 2].

Meat and meat processing industry, is among the least profitable industries despite its immense size and large gross sales. Effective recovery and utilization of by-products and wastes is the lifeline of meat and poultry processing industry. Thus, it becomes imperative that an effort be made to reduce expenses by employing the use of new or modified processing methods and through in-plant treatment, where waste effluents and by-products could be recovered and often upgraded to useful products of higher value. Meat processing wastes have a potential for recycling raw materials or for conversion into useful products of higher value as by-product or even as raw material for other industries or for use as food or feed after biological treatment.

Key words : Glaciers, Glacial Lakes, Glacial Lake Outburst Floods (GLOF), Himachal Pradesh, Glacial Inventory, Glacier Recession.

Introduction

Glaciers are large masses of snow, re-crystallized ice and rock debris that accumulate in great quantities and begin to flow outwards and downwards under the pressure of their own weight. Glaciers form when yearly snowfall in a region far exceeds the amount of snow and ice that melts in a given summer. In this way, massive quantities of glacial material accumulate in relatively small periods of geologic time. The glaciers exist in environments of high and low precipitation and in many temperature regimes; they are found on all the continents except Australia and they span the globe from high altitudes in equatorial regions to the polar ice caps. Presently, 10% of the Earth’s land area (5.8 million square miles) is covered with glaciers storing about 75% of the world’s freshwater. However, during the last Ice Age, glaciers covered 32% of the total land area of the planet.

Key words : Integrated Watershed Management (IWM), GIS, DTM, Watershed Delination, Water Quality Modeling, RS, DSS, Ground Water Information System (GWIS).

Introduction

The availability of land and water resources has a major effect on the economic and ecological aspects of life everywhere around the world. As a result, the need to develop better tools for efficient land and water resources management has become very vital. For quicker, reliable and precise results, it is necessary to use the geospatial tools and techniques such as Global Positioning Systems (GPS), Geographic Information Systems (GIS) and Remote Sensing (RS) image interpretation and analysis techniques to manage the natural resources. The application of these tools and techniques not only facilitates timely and repetitive analysis of all the topological features, but also assists in development of Decision Support Systems (DSS) to generate alternative scenarios for optimal use of the natural resources in the long term. The optimal use of these resources through integrated management of land water and vegetation leads to enhanced production and productivity of food, fodder, fiber, fuel, fish, flower and forest resources. Moreover, the holistic management of the resources to produce these outputs is plausible and manageable within the watershed systems, which are hydro geological units from which the runoff resulting from precipitation flows past through a single outlet to downstream locations. The systematic management of land, water, vegetation and livestock resources within the watershed systems is termed as Integrated Watershed Management (IWM). Broadly, IWM can be defined as a multidisciplinary, holistic way of protecting and managing a watershed’s natural resources to enhance biomass production in an eco-friendly manner. The watershed is viewed as a hydro-geological complex and dynamic ecosystem in which natural and anthropogenic processes occur and interact resulting in generation of runoff at the watershed outlet.

It is well known that lowering the temperature of food stuffs reduces microbiological and biochemical spoilage and thus extending the shelf life of the product. In addition, it is generally agreed upon that the reaction rate is reduced by half by lowering the temperature by 10°C. Though low temperature preservation process has been recognized as a preservation technique for several hundred years, the major developments in its utilization have occurred only in the last century.

Annuals, commonly known as seasonals, constitute an amazing group of popular flowering ornamentals widely grown in all types of parks and gardens. Enchanting colours of the flowers in various shades, forms and fragrance have made them an obvious choice for all garden lovers. Perennial plants like trees, shrubs, climbers usually form the framework of garden. However, they produce flower in a particular season and the garden remain out of flowers for considerable period of time. On the other hand, annuals serve as toppings in every season with a colouful flower plate and complement the perennials. No other plants can influence the general landscape in such an incredible manner by splashing colours and quick performance.

Botanically annuals are the plants which normally complete life cycle within one year. However, horticulturally annuals refer ornamental herbaceous plants grown in different seasons of the year for flowers and aesthetic purpose. As the winter sets in and the annuals start blooming, face of the garden alters into a vivid beauty. Easy cultivation and availability in wide array of dazzling colours have made them most popular in Indian gardens. Annuals are like jewels of the garden which magnifies beauty of the other permanent plants and features by adding colour.

Whenever we get a cut, a red fluid comes out of the wound. This red fluid is called blood. Blood is very important for the body as is evident from the fact that the loss of blood from the body makes it weak and may even cause death. Physiologically the blood is a red tissue composed of cells suspended in a pale yellow fluid, plasma. Unicellular organisms that live in immediate contact with the external environment obtain nutrients directly from that environment and eliminate unused or unwanted materials. Blood and lymph are important connecting fluids among the diverse anatomical structures of the mammalian organisms. Thus blood is the liquid vehicle by which the major organic nutrients are transported from the intestine where they are absorbed, to the liver where they are processed and thence to other organs. Similarly blood is the liquid vehicle for the transport of waste materials from various organs to the kidney and gastrointestinal tract from where they are eliminated. Thus the blood is the major transport carrier of nutrients, metabolites, oxygen, hormones, waste products etc. inside the body. Blood is an important medium to maintain homeostasis of various electrolytes in the body. Besides blood provides the army against any external attack on the body by harmful microorganisms. This army is in the form of cells, called white blood or corpuscles or leucocytes.

In a normal adult human being, about 5 to 6 litre of blood is present which is about 8 percent of the body weight. In domestic animals generally 5 to 8 per cent of the body weight is blood (say 30-40 litre in a cow). The blood is composed of two parts, the cells and the fluid part or plasma. The cellular constituents of blood include erythrocytes or red blood corpuscles, leucocytes or white blood corpuscles and thrombocytes or platelets. The cellular constituents of blood varies with the species as well as with the age and physiological stage of the animal.

The extracellular constituents or plasma is composed of water, electrolytes, proteins, lipids, glucose, enzymes and hormones etc. The blood undergoes coagulation on exposure to air leaving clear watery fluid, called serum. The serum is nothing but plasma minus fibrinogen and other clotting factors. The serum is a clear yellowish fluid. The yellow colour is due to the presence of small quantities of bilirubin, a bile pigment and of carotenoids. The blood serum of cattle is yellow due to presence of more of carotenoids whereas that of buffalo is white due to the absence of carotenoids. The blood clot consists of a network of fibrous strands of fibrin in which are enmeshed the cellular elements of the blood. Blood clotting is a protective mechanism against excessive loss of blood from the body. The lymph also clots, although, somewhat more slowly than blood.

I. INTRODUCTION

Nations are growing with pace in technology and technological advancements. Till the end of 20th century development was the priority of entire planet earth but in the ending of the 20th century it was realized by almost all countries that development cannot go alone but it has to have the social, economic and environmental concerns. It was realized by the United Nations in Rio Conference on Environment and Development, 1992 that there is need of sustainable development. Now in 21st century the technological advancements are needed to be utilized for saving the planet earth from the curse of climate change and global warming reducing the carbon emissions across the entire planet earth. The argument in this paper is based on, how far technological advancements and technology transfer, by developed countries to developing countries can be facilitated in reduction of the carbon emission and greenhouse gases, through legally binding norms? How there should be synergy in between technologies reducing carbon emission and IPR issues?

Financing the Business

The capital of a business consists of those funds used to start and run the business. Capital may be of two types: fixed and working.

Fixed capital refers to items bought once and used for a long period of time. This includes such things as building, fixtures and equipment. Fixed Capital does not vary with the level of output.

Working capital is the type of funds, which is needed for carrying out day-to-day operations of the business smoothly. The management of working capital is no less important than the management of ‘long term‘ financial investment. Working Capital varies with the level of output.

In old days, Statistics is considered as a method for collected numerical information. In general, Statistics deals with concepts, principles and methods dealing with collection, summarization, analysis and interpretation of data. Data means a collection of numerical facts. Data is plural and singular is datum. Generally there are two classifications for data, quantitative and qualitative. In the case of quantitative character the individuals are measured. While in the case of qualitative character, the individuals are distinguished by some quality. Data collected by the investigator for the purpose of the investigation are known as primary data. E.g., data obtained in a population census. Data collected by others for some other purpose and is used by the investigator are known as secondary data. E.g., Annual Reports, Official publication etc. The aggregate of all the observations pertaining to a character is called a population. Sample is a part of the population selected according to some definite rule. Usually the sample is used to make an inference about the population. In other words sample is a miniature of the population. The methods by which we analyze the data are called statistical methods. At the end of the enquiry, the investigators will naturally left with a large number of filled up schedules and a very efficient statistician couldn?t interpret anything from it unless it is classified and extracted. When we classify based on the quality like colour, sex, religion etc. which can?t measure directly, the classification is qualitative. But characteristics such as height, weight, length, time etc. can be easily measured using a scale. Such are called quantitative characteristics. The quantitative characteristics may be discrete or continuous. In the case of numerical values like number of petals in a flower, number of days in which rain occurred in a month etc. are whole numbers and are called discrete variables. If there may occur many values with in an interval, we call it as continuous variables.

Abstract

Kaliasaur landslide located 18km from Srinagar on the NH-58 in Uttrakhand Himalayas has been repeatedly sliding for the last over 5 – 6 decades totally paralyzing the transport operations in the region and causing beeline of issues not only for the people living in the hilly state but also the tourists and the pilgrims. The study of Geosystems & geodynamics, large scale micro zonation and geotechnical studies using RMR and SMR techniques show that the slide is located in high hazard zone and follow the pattern of wedge and planar failures with vulnerable zone of factor of safety. The toe erosion by the acutely turning Alaknanda river and the mitigation measures in the form of slope disturbance in the upslope part rather protecting slide, has been responsible for the recurring slides. The study further revealed that excessive rainfall is also a triggering parameter and the crown part is widening. On the basis of the studies, mitigation measures have also been brought out.

Keywords: Kaliasaur landslides, Micro LSV zonation, Factors of landslides, Mitigation.

INTRODUCTION

The term ‘ginseng’ is applied to a range of plants from family Araliaceae involving genus Panax. Out of the many species available in nature, Himalayas are also home to a commercially lesser known variety called as Panax psuedoginseng Wall (Nayar and Shastry 1990). In the interior temperate areas of the eastern Himalayas, the species is distributed across Sikkim, Bhutan, Nepal, and extends into China. Keeping in view its high commercial international demand, CSIR-Institute of Himalayan Bioresource Technology (CSIR-IHBT) Palampur has recently taken an initiative to introduce and cultivate Chinese ginseng (Panax ginseng) in the Lahaul valley of Himachal Pradesh, in India. This chapter addresses the different biological, chemical, medicinal and cultivation aspects of both the indigenous Himalayan variety (P. psuedoginseng) and the introduced Chinese species (P. ginseng) in particular.

Introduction

Picrorhiza kurroa Royle ex Benth is an important alpine medicinal plant of the Himalayan region. The root and rhizome of P. kurroa are source of the crude drug, which is characteristically bitter in taste and is linked to the medicinal properties. In Indian system of medicine, the species popularly known as Kutki, is an important constituent of several drugs items. This plant also finds a place in Chinese system of medicine where it is known as Hun-hung lien. Chemically, compounds of interest in Picrorhiza are iridoid glycosides: picroside-I and picroside-II. Material for crude drug has traditionally been extracted from the wild. Natural stands have sharply dwindled due to over extraction and habitat degradation. The species was listed as “endangered” in 1997 by International Union for Conservation of Nature (IUCN). Commercial cultivation is not popular, but is urgently recommended.

10.1 Introduction

Food safety and quality are the two important factor which results in consumer food choices. Nowadays consumers are demanding food which is safe and of high quality in terms of nutrition due to a healthier life style. Food safety and quality are the terms used interchangeably. Food safety refers to all those hazards, that make food injurious to the health of the consumer and it is not negotiable. Food quality includes attributes that influences the product's value to the consumer. This includes both negative and positive attributes; negative attributes includes spoilage, contamination, discoloration, off-odours and positive attributes include colour, flavour, texture and processing method of the food. This distinction between safety and quality has implications for public policy and influences the nature of the food control system. Food control is defined as a mandatory regulatory activity which provides consumer protection and ensures food is safe, wholesome and fit for human consumption during production, handling, storage, processing, and distribution.

Despite the huge efforts made by the food safety authorities and industries, food safety still remains a critical issue. In food industries, producers have to satisfy both safety and quality criteria for their products to the consumer. Food processors have multiple options in terms of different quality and management systems, they have to choose the most appropriate one for its specific activity and should establish, document and implement effective systems in the processing area for managing quality and safety of the product. Over the past few decades, food-borne illnesses have raised great concern about the safety of food. Considerable steps are taken by the food processor for understanding and managing the risks of airborne diseases. Among various systems, Hazard Analysis and Critical Control Point (HACCP) is effective tool which focuses mainly on controlling hazards to ensure the production of safe and wholesome food. For maintaining the safety and increasing the shelf life of food, traditionally it has been preserved by thermal processing, freezing, salting and drying. But nowadays consumers are demanding convenient, innovative, fresh foods, including new "minimally processed" products. To meet consumers' expectations in the 21^st century, the food industries are implementing novel technologies whose purpose will be two fold: 1) to provide the new quality attributes demanded by consumers; and 2) to ensure the all important and often expected assurance of food safety. The novel technologies will include various minimally processed technologies like high pressure processing (HPP), pulsed electric field (PEF), ohmic heating, dielectric heating, microwave heating, ultrasound, modified atmosphere packaging (MAP) and cleanroom technology. Among these cleanroom technology have attracted great attention for maintaining the safety and quality of the food products as because it doesn't have any effect on the nutritional quality of the food being processed, it maintains the hygienic condition in the processing area, remove contaminants from the processing area and clean air in the processing area which in turn results in safe food product. The main objective of cleanroom technology is to eliminate airborne contaminants from the humans and/or from the environment. An air curtains and a positive air pressure is maintained in the processing unit using filtered air. Production personnel will use the special clothing which is preferred for cleanroom to reduce the contamination from both air- and human-borne microorganisms. In this chapter we will discuss about cleanroom technology, its historical background, its classification, layout of cleanroom, air handling, personnel and its clothing, regulations in cleanroom, and its application in food industries.

Milk is the secretion of the mammary glands of animals. For human consumption, milk is that liquid obtained from the cow or the buffalo during the period following at least 72 hours after calving or until the milk is colostrums-free. It is a complex biological fluid consisting of seven main components: water, fat, protein, sugar (lactose), minerals, vitamins and enzymes. Milk is a white opaque fluid in which fat is present as an emulsion, protein and some mineral matters in colloidal suspension and lactose together with some minerals and soluble proteins in true solution. The opacity of milk is due to its content of suspended particles of fat, proteins and certain minerals. The colour varies from white to yellow depending on the carotene content of the fat. Skimmed milk is more transparent with a slightly bluish tinge. Milk of a good flavour has a pleasant, slightly sweet taste, and no odour. It is an excellent source of calcium, phosphorous and riboflavin. Vitamin A and D are currently added to whole milk, partly skimmed and skimmed milk.

Cleaning and sanitisation are the two processes employed in dairy industry to ensure hygiene and product safety. The safety of milk and milk products is a very important aspect and every attempt should be made, during processing, to minimize contamination through handling and processing equipments. The accumulated dried milk solids (milk stones) consist largely of calcium phosphate, milk proteins (precipitated, coagulated and baked on by heat) and insoluble calcium salts from water and washing detergents. The surface can also contain biofilms, which are formed by the incorporation of bacteria into the accumulated inorganic and organic materials that attach to most surfaces. With time and in the presence of nutrients, a biofilm and the bacteria within the biofilm will grow and become strongly attached to the surface. The removal of dairy soil, milk stones as well biofilms is the prime objective of the cleaning process. International Dairy Federation (IDF) defines a clean surface as one which is free from residual film or soil that will not contaminate the food products coming in contact with it.

While cleaning refers to the removal of soil from the surface of the equipment, sanitisation implies destruction of all pathogenic and almost all non-pathogenic organisms. Cleaning and sanitisation are complimentary processes. Either of the processes alone will not achieve the desired result, which is to leave the surface as free as possible from soil and viable organisms. In actual practice cleaning and sanitisation overlap to some extent, as during cleaning a high proportion of bacteria are destroyed and others get removed in the detergent solution. Inadequate or faulty cleaning and sanitisation can have serious consequences, as milk is a prefect nutrient in which bacteria can multiply. A thorough understanding of the cleaning methods is, therefore, necessary for economic production of high quality food products.

Dietary constitution of Indian people is mostly cereal based. However, the cereals supply chiefly carbohydrates. Therefore, there is deficiency of protein, minerals and vitamins, especially vitamin A, riboflavin, vitamin C, etc. in the diet. The dieticians advocate the intake of 125 g leafy vegetables, 75 g other vegetables and 100 g root and tuber vegetables (total 300 g) everyday because vegetables provide all the nutrient components like carbohydrates, protein, fat, minerals, vitamins and water along with roughages, which are the essential constituents of a balanced diet.

India has attained food security by increased cereal production due to green revolution. In case of vegetables, although there has been increase in production from 15 million tonnes during 1950 to 94 million tonnes in 2005 but still more vegetables are needed to meet the minimum requirement of at least 250 g per day per capita. There has also been increasing demand for fresh export and for processing industries. Moreover, there is a pressure for increasing vegetable supply caused by constantly increasing population in a world of limited acres.

Addition of new agricultural land is of course not possible. In this situation, plant breeding can be expected to contribute substantially to greater vegetable productivity. This can be accomplished not only by the breeding of basically higher yielding varieties but also by the development of varieties that help to stabilize production through resistance to various biotic and abiotic stresses.

Organic agriculture or farming is very much native to India. Whosoever tries to write a history of organic farming will have to refer India and China. The farmers of these two countries are farmers of 40 centuries and it is organic farming that sustained them. This concept of organic farming is based on following principles:

• Nature is the best role model for farming, since it does not use any inputs nor demand unreasonable quantities of water.
• The entire system is based on intimate understanding of nature’s ways. The system does not believe in mining of the soil of its nutrients and do not degrade it in any way for today’s needs.
• The soil in this system is a living entity.
• The soil’s living population of microbes and other organisms are significant contributors to its fertility on a sustained basis and must be protected and nurtured at all cost.
• The total environment of the soil, from soil structure to soil cover is more important.

ABSTRACT

Dysoxylum binectariferum Hook.f. (Meliaceae) is phylogenetically related to the Ayurvedic plant D. malabaricum. D. binectariferum has been identified as an enriched source of rohitukine, an alkaloid. Two synthetic flavones, flavopiridol (Alvocidib; L868275; HMR-1275; NSC 649890 of Sanofi-Aventis + NCI) and P-276-00 (Piramal) are advanced in clinical trials for the treatment of cáncer. These two molecules are considered as potent Cdk inhibitors. Cdk has been discovered as a key regulator of cell cycle. Therefore, Cdk inhibitors or modulators are of great interest to explore as novel therapeutic agents. These two molecules can be considered as rohitukine inspired drugs since their stuructural novelity originated from a compaign to develop a route of total synthesis of rohitukine. Recently a semisynthetic derivative of rohitukine; IIIM-290 has been emerged as potential preclinical cyclin-dependent kinase (Cdk) inhibitor. Moreover, phytochemical investigation of D. binectariferum yielded dysoline a new region-isomer of rohitukine. Dysoline seems to be a potent inflammatory and cytotoxic compound. Similarly, camptothecine and 9-methoxycamptothecine were isolated from Dysoxylum binectariferum for the first time by bioassay-guided fractionation. Present chapter is reviewing some original work which were carried out at CSIR-Indian Institute of Integrative Medicine, Jammu, India. The present studies focused on the phytochemistry of Dysoxylum binectariferum; dysoline, camptothecin and 9-methoxycamptothecin and medcinal chemistry and preclinical evaluation of IIIM-290 a semi-sythestic derivative of rohitukine.

1. Introduction

Plant taxonomy and the cultivated plants have a close relationship of great antiquity. This ancient relationship can be traced back to the invention of incipient agriculture (neolithic revolution), about 10-13000 years BCE (Stearn 1965; Balter 2007). The early foundation of plant taxonomy was thus laid largely on humans’ knowledge on cultivated plants. This body of rudimentary knowledge on identifying the properties of different types of plants for food, medicine, clothing, shelter, and other uses led to the development of plant taxonomy- the first aspect of plant science to emerge as botany (Constance 1957). The fundamental principles of modern plant taxonomy with regard to the natural vegetation and flora were originally derived from cultivated plants (Li 1974).

The active process of cultivation of a plant, primarily through the intentional activity of humans has been considered the main criterion for categorising cultivated plants (Mansfeld 1959). According to Mansfeld’s approach, the number of cultivated plant species of the world was estimated to be about 7000 species, excluding partly the forestry plants, ornamentals, and plants used in amenity horticulture (Henelt and IPK 2001). Khoshbakht and Hammer (2008) expanded this list to include a total of 35000 species of cultivated plants, including 28000 ornamental plant species connected to gardening and landscaping. About 2500 plant species have undergone domestication worldwide, with over 160 families contributing one or more crop species (Zeven and de Wet 1982; Dirzo and Raven 2003).The growing numbers of cultivated plant species and the enormous diversity found in each of these species offer plenty of challenges as well as opportunities to the taxonomists to take up cultivated plant taxonomy as an active scientific pursuit. Despite this, there has been a lack of interest among taxonomists towards cultivated plant taxonomy.
