7.1 Introduction

The earth's crust is made up of igneous, sedimentary and metamorphic rocks. Each variety of rocks exhibit some columnar joints in Igneous rock, characteristic structures like bedding in sedimentary rocks and fabrics like schistosity and gneissosity in metamorphic rocks.

As a result of tectonic activities in nature, rocks may suffer deformation, rupture, dislocation of beds (Fault) or other planar structures.. The whole study of such deformation is known as structural Geology. It has been observed that sedimentary rocks are most suitable for studying structures, because these rocks are deposited in quiet environment, and initially the beds arranged in horizontal position. As a result of stress due to kinematic movements/tectonism, the horizontal beds tend to deviate from their horizontal disposition to dipping position or get folded or faulted. Thus the rock develops various kinds of structures. There are following structures present in sedimentary rocks:

Application of the principal of geomorphology provides information, which will be of value in predicating the geometry of aquifers. On weathering and erosion, many geological formations develop landforms that are distinctive in respect of slope continuity of outcrops and symmetry of valley flanks. The surface topographic features of bedrocks can some times be extrapolated to reasonable depths to predict the thickness of alluvium or aeolian sands occurring as valley fill deposits, by treating slope profile as mathematical curves for which equations similar to regression equations can be found (Doornkamp and King, 1971).

The influence of tectonic movements and resultant structural features on landform is of paramount importance for hydrogeomorphologists. The control of structure on landforms and hydrogeological processes are being discussed here. The structural geology concerns with the features such as uniclinal or inclined beds, folds, faults and joints. Of these the structural features like faults, fractures, joints etc appear as linear feature.

Linear features on the surface of the earth have attracted the attention of geologists for over one hundred years. This interest has grown most rapidly since the introduction of aerial photographs into geological studies. Geologists have recently proven that various structural features perceived in remotely sensed images are reliable indicators of geologic resources (Caran et al, 1982). These structures have been used in many applications: petroleum and mineral exploration (Blanchet, 1957); nuclear energy facility siting (Seay, 1979); geothermal assessments (Woodruff et al, 1982); and water resource investigations (Lattman and Parizek, 1964). Lattman and Parizek (1964) established a relationship between the occurrence of groundwater and fracture traces for carbonate aquifers, and in particular zones of localized weathering and increased permeability and porosity underlying these structures.

Introduction

Bundelkhand is an important region of Central India which is often called as heartland of the nation. It is spread in the geographical area of 7.08 mha, includes 14 districts seven, each of Uttar Pradesh and Madhya Pradesh and supports 1.84 crore (as per 2011 census) of socio-economically and culturally diverse population. The present region of Bundelkhand lies between approximately 23°10’ and 26°27’ (north) latitude and 78°4’ and 810 34’ (east) longitude. It lies between the Indo-Gangetic Plain to the north and the Vindhya Range to the south. Bundelkhand is a hot and semi- humid climate with highly variable depending on the region and with gently sloping upland, distinguished by barren hilly terrain with sparse vegetation, although it was historically forested. As with the rest of the Indian sub-continent, Bundelkhand experiences two main seasons, monsoon and dry. The monsoon brings over 90 percent of the annual rainfall between the months of June and September with the highest precipitation occurring in July and August. On an average, the region receives 75 cm to 125 cm of rain each year. The dry plains in the north usually receive less rain compared to the south- eastern part of the region. Minimum temperature varies from around 6-12 ^?C and maximum temperature varies from 38- 48 ^?C.

The region is blessed with plenty of natural resources. It had truly been endowed by nature, with beautiful mountains, good perennial rivers, fast flowing seasonal rivulets, large rich forest areas with valuable timber, fruit trees, numerous medicinal plants / herbs in almost each district. The rainfall here had been on average much better than many parts of India. Bundelkhand is a part of the central zone of India with a group of north-bound perennial rivers flowing and paying tribute to river Yamuna. From west to east these are Sind, Pahuj, Betwa, Dhasan, Ken, Baghein Paisuni and Tons. Along with Chambal and Yamuna these are ten major rivers. Other water resources in Bundelkhand are in form of water stored / conserved on surface termed as ponds, tanks, lakes etc. Bundelkhand has, undoubtedly, been one of the regions in India very much known for its historical rain-water management through man-made ponds, tanks and lakes. Topography here helped to build such structures but more than anything it reflected fore-sight and positive attitude of those rulers towards conservation of nature.

Introduction

India is considered as one of the emerging superpowers of the world. This potential is attributed to several indicators, the primary one being its demographic trends and a rapidly expanding economy. In 2015, India became the world’s fastest growing economy with a 7.5% estimated GDP rate. But in the year 2020, the pandemic lockdown situation created adverse impact on the global economy. At this juncture, there is an urgent need to focus on native and indigenous resource mapping and judicious utilization of it to be a self-reliant. The COVID-19 pandemic has necessitated a new set of reforms to strengthen the economy. The first mention of this came in the form of the ‘Atmanirbhar Bharat Abhiyan’ or ‘Self-Reliant India Mission’ by the Government of India during the announcement of the coronavirus pandemic related economic package on 12^th May 2020. Almost 70% of India’s population depends directly and indirectly on agriculture for their survival. This means the country cannot have a development model that ignores agriculture.

It’s time to take a look at India’s agriculture economy. Over the last 10 years, (2008-19) India has been a net exporter of many farm produce. In fact, in 2018, the government has come up with a new agricultural export policy aimed at doubling farm income by 2022. However, in 2019-20, agri-exports were just $36 billion and the agri-trade surplus was $11.2 billion. The net agri-trade surplus has been falling over a period of time, making it difficult to achieve doubling of farmers’ income and doubling of agriculture exports by 2022as well.

India is not yet self-reliant in various essential agriculture commodities and depends heavily on imports. India imports around 15 million tonnes of edible oil every year — more than 9 million tonnes of palm oil and about 2.5 million tonnes each of soybean oil and sunflower oil. It buys palm oil from Indonesia and Malaysia, and soy and sunflower oil from Argentina, Brazil, Ukraine and Russia. There is a need to create self-reliance in theses commodities enhancing productivity of Indian farms to create competitive advantage for domestic producers. India can step up cultivation of sunflower, groundnuts, mustard and oil palms. Presently, India has about two million hectares of land that is suitable for oil palm cultivation.

Abstract

The tradition of growing of flowers is age old. The flowers have travelled from the bowl of prayers to gardens to commercial sector for revenue. The quality concerned world demands for round the year production and supply of quality produce which can only be possible under controlled environment production. A range of location specific and crop specific infrastructures are being commercially used for production of planting material and flowers. General and crop specific guidelines for trade of cut flowers are available which the producers and policy makers must know for successful promotion of export of cut flowers from the country. The producer can also use practical methods for vase life study of their produce which is of great relevance in cut flower trade.

Keywords: Protected floriculture, trade, crop specific guidelines, export, cut flower

Introduction

Indian floriculture industry is shifting from traditional flowers to cut flowers for export purpose. The liberalized economy has given an impetus to Indian entrepreneurs for establishing export oriented units (EOUs) under controlled climatic conditions. The wide variations in agro climatic conditions in India permit us to grow various types of tropical and subtropical flowers. Though such plants grow successfully in open conditions without cover, they fail to meet the quality requirements of being blemish free. High quality ornamental plants meant for export should be scientifically grown only in plastic, glass or fibre glass greenhouses or at least under partial cover. Though initial investment is high in protected cultivation, the products in them will obtain far more attractive prices.

Structure

Structural unit of edible portion of most fruits and vegetables is the parenchyma cells and makes up bulk of cells. A parenchyma cell is rather thin walled and may be polygonal or cubical in shape.  Walls of parenchyma cells in young plants are composed almost entirely of fibrils of cellulose. In parenchyma cells of plants actively metabolising protoplast portion represents only about 5% of total cell volume. This protoplast is rather film like and is pressed against cell wall by large water filled central vacuole.  Protoplast has inner and outer semi permeable membrane layers between which is confined cytoplasm and its nucleus. 

2.1. Structure of fruits and vegetables

2.1.1. Fruit

• Fruit is a part of a flowering plant that derives from specific tissues of the flower, mainly one or more ovaries (Fig. 1). Plant product with aromatic flavors, which are either naturally sweet or normally sweetened before eating.

2.1.2. Vegetables

• It exhibits wide verity of plant structure like edible seeds, roots, stems, leaves, bulbs (Fig. 2), tubers and non-sweet fruits of herbaceous plants.

• Vegetables are grouped into 3 main categories

? Seeds and pods-contain natural wax coating. Eg. Many legumes

? Bulbs, roots and tubers with no coating, but tuber has suberisation

? Flowers, buds, stems and leaves having low shelf life

The word meat comes from the old english word mete, which referred to food in general. Most often this means the skeletal muscle and associated fat but it may also describe other edible tissues such as organs, livers, skin, brains, bone marrow, kidneys and lungs etc. In other words we can say meat is those animal tissues which are suitable for use as food by the man. It is composed of numerous types of tissues like muscle tissues, epithelial tissues and nervous tissues but the major component of meat is muscle. Particularly skeletal muscle is the principal source of muscle tissue in meat while smooth muscle contributes little to meat. The muscle and connective tissues are the major compositional components and contributes towards qualitative and quantitative characteristics of meat. Broadly muscle can be classified into striated and smooth muscles. Striated muscles have transverse band pattern as seen in skeletal and cardiac muscle. However, smooth muscles do not show such pattern and mainly found as a component of blood vessels.

ABSTRACT

Homegarden is a least studied agroecosystem of the world. Present study, conducted in 430 homegardens before Tsunami in five island groups namely North Andaman, Middle Andaman, South Andaman, Car Nicobar and Noncowry (former three, Andaman group and later two, Nicobar group of islands), India, reports composition, species structure and its distribution and functioning of the system. The homegarden is comprised of 6 components i.e., garden, livestock, poultry, fishpond, homesteads, and rice fields. Coconut and arecanut trees predominate in the garden. Fruits, spices and agroforestry trees are other ligneous species, which together with the former trees form multistorey canopy structure. But, composition and dominance of the tree species vary across the islands. Arecanut to coconut ratio is greatest invariably in all the homegardens in the Andaman. Family members do maximum 70 per cent labour in the homegarden and consume 35-65 per cent fruits, poultry, livestock and fishpond products, however, surplus is sold. Free range grazing in nearby protected forests is an age old practice of animal feeding whereas poultry birds are fed among the garden trees and household refuge. Livestock includes cattle, buffaloes and goats in Andaman and pig and goat in Nicobar. Cattle are used for milk, he buffaloes as a draft animal and pig and goat for meat. Cattle, mostly local breed, yield a little amount of milk, an average, 1 liter cow-1. Plantation crops production is low: coconut 18-30 nuts palm^-1 and arecanut 0.75 kg palm^-1. The homegardens serve the subsistence as well as earn income, but low (US$ 2357) to the house. In Nicobar, Nicobarese huts interspersed in a big natural coconut plantation form the homegarden. Tribe Nicobarese do not know crop husbandry, rather they pursue round the year sea fishing and pig rearing. They relish most pork, unripe boiled wild banana, Nicobari tuber, fruits and seeds of Pendanus and fried fish.

The heart failure is an important cause of morbidity and mortality in animals and man. It is the end stage complex event of cardio-vascular diseases. For having a better understanding of heart failure in animals for adopting rational therapeutic management, it is utmost necessary to have thorough knowledge about heart, its structures, its nerve supplies, its vasculature, current generation and conduction as well as its functioning in the healthy subjects.

Kidney is one of the main excretory organs of the body. By secreting urine the kidney serves as the outstanding guardian of the milieu interieur. The main functions of the kidney in the maintenance of body homeostasis are listed below.

1. Maintenance of proper osmotic concentrations.
2. Maintenance of blood volume.
3. Maintenance of ion concentration.
4. Removal of nitrogenous end products of protein metabolism primarily urea, creatinine and ammonia.
5. Removal of foreign substances and/or their metabolic end products.

Thus, kidney control the concentration of most of the constituents of body fluids. In case of birds, the primary end product of protein metabolism is uric acid instead of urea. So, the major excretory product through urine in case of birds is uric acid.

Briefly, the kidney form urine in the following way. Endowed with a relatively huge blood supply, the renal glomeruli filter about 200 litres per 24 hours of protein free fluid from the blood in human being ( ie 50-60 times the plasma volume). This filtrate, which contains the soluble non protein components of the plasma, is submitted to extensive reabsorption by the renal tubules. The relative control on the reabsorption process by the kidney, is the key mechanism by which the kidney is able to maintain the composition of the milieu interieur.

Kidney also releases several hormones like renin, erythropoietin and prostaglandins, which have the capacity to influence cells and alter their physiological processes.

Substances which are in excess of the body and/or are harmful need to be removed constantly. This function is carried out by the excretory organs which include skin, gastrointestinal tract and kidney. Skin excretes water and salts in the form of sweat. Gastrointestinal tract removes undigested food material as well as some heavy metals in the form of faeces. Kidneys are the main excretory organs which together with a pair of ureters, a urinary bladder and urethra constitute the excretory system. Renal function is essential for homeostasis.

Structure of a business or legal framework

1. Sole proprietorship: A private company is a form where an individual is the exclusive proprietor of the business. It constitutes a straightforward setup where the owner is one person who manages the everyday operations of the company. In this case, the business is not regarded as an independent entity. Therefore, earnings and debts are merged into their personal accounts, which are assessed and taxed at the individual level.

Advantages of the sole proprietorship structure include

• Complete Control: As a sole proprietor, you have the right to make all business decisions and do not have to negotiate with other partners, managers or shareholders as in other structures.

• Easier Startup: The creation of a private company does not necessitate completing forms or remitting a state fee. This can ease the procedure and render it more affordable.

• Simple tax reporting: Because a business is not legally a separate entity, your income tax return includes the expenses and income of the business. As an added bonus, you can use business losses to offset your earned income, which can result in a higher taxable income.

• Privacy: Sole proprietors do not have to file annual reports with state or federal governments. Therefore, the company is not disclosed in the same way as in other structures.

Bacteria can be defined as a group of diverse and ubiquitous prokaryotic single cell microorganisms. The size of bacteria varies with genera/species. In cocci the diameter varies between 0.5-1 µm. The measurement of bacillus / rod shaped bacteria is 4-8 µm ? 1-1.25 µm. The surface area and volume ratio of bacteria is very high. The nutrients are absorbed through a large surface area and it is rapidly distributed into a small volume. So the growth rate and metabolism of bacteria is very high. The bacterial cell mass is packed near the surface and no circulatory system is required to distribute the nutrients. The growth and metabolism rate of bacilli are more than cocci because surface area and volume ratio of a sphere (cocci) is lowest among all the geometrical forms.

Shape of bacteria

The shape of bacteria is mostly regulated by the rigid cell wall covering the bacteria. Different shapes of bacteria are observed.

The information that drives the process of life is encoded in the genome of the organism. Structurally defined, a genome is an organization of genetic information consisting of nucleic acids (deoxyribonucleic acid or ribonucleic acid). Arrangement of nitrogenous bases in the nucleic acid codes the information for execution of cellular processes. Four types of bases (Adenine, Guanine, Cytosine and Thymine) are present in deoxyribonucleic acid (DNA) while in RNA Uracil replaces thymine group of any three bases on transcribed RNA represent a codon. With four types of bases, sixty four types of codons can be formed. Genetic information encrypted in these codons is released in the form of arrangement of polypeptides consisting proteins via mRNA intermediate. This universal process of flow of genetic information from DNA to RNA to protein is known as the central dogma of life. The whole set of information coded in 64 codons, out of which 61 codes for one or more amino acids (building block of polypeptides/proteins) and three indicating where to stop is called the book of life or genetic code.

X-ray diffraction (XRD) is an important experimental tool used in determining crustal structure of material system in bulk and nanoregimes. Therefore, it is important to understand the basic concepts of XRD.

3.1 Introduction

Eggs are composed of three main parts; the eggshell with the eggshell membrane, the albumen or white, and the yolk. The yolk is surrounded by albumen, which in turn is enveloped by eggshell membranes and finally a hard eggshell.

3.2 Eggshell

The eggshell is composed of a foamy layer of cuticle, a calcite or calcium carbonate layer, and two shell membranes. The ultrastructurally the eggshell includes shell membranes, mammillary zone, calcium reserve assembly, palisades, and cuticle, with 7,000 – 17,000 funnel shaped pore canals distributed unevenly on the shell surface for exchange for water and gases

Size shape and Appearance of Bacterial cells

Bacteria vary significantly in their morphology, that is in their appearance. They range in size from 0.2 μm to1 μm in diameter and 1 μm to 10 μm in length. There are three basic shapes of cells :

1. Spherical

2. Rod-shaped

3. Spiral.

Motives of joining SHG

Sensitization for joining SHG does not alone help to achieve immediate result. Motives when combined with inspiration, an individual is tempted to act so also the case with sample SHG who expressed motives for joining SHG as follows.

Even though we are now in the atomic age, the idea of the atom is not new. More than 2,000 years ago, the Greek philosopher Democritus suggested that any matter is composed of tiny indestructible particles called Atoms. The word atom is derived from the Greek word Atoms meaning something that can not be cut further. However not much attention was paid to this concept till 1808, when Dalton proposed the famous “Atomic theory”. According to this theory, “all matter is composed of tiny indivisible particles called ‘Atom’. Combining the ideas of Lavoisier, Boyle and his own, Dalton proposed that atoms of elements combine together to make molecules of a compound. This was a great step in the concept of the atom and compounds, since this gave a clear picture of how the supposedly smallest particles of matter called atoms could be put together to form the various familiar substances found in nature.

The chromosomes provide physical basis by which genetical stability and continuity of individuals and populations are maintained in each generation. Chromosomes also play an important role to generate variation which is an essential component of evolutionary process. Although crossing over during meiosis is responsible for generation of variability, but structural changes in chromosome too are important for causing variation and evolution, since genetic and cytological analysis of individuals of related species or isolated populations within the species have shown that they may differ by various kinds of changes in their chromosomal structure. The structural changes usually may result from spontaneous chromosome breakage. But under normal condition/s such breakage is an rare event and its frequency is dependent upon environmental conditions, i.e., temperature, various high energy radiations (e.g. X, λ and β-rays) and some chemicals. Chromosome breakage is reported to be higher in some hybrids and in presence of particular genes. Certain chromosomes and chromosomal segments (centromeric and other heterochromatic regions) are more likely to undergo breakage. But stability and continuity of structural changes in the chromosomes depend on the behavior of the broken ends. There is no change if broken end rejoins at the same chromosome but a change may occur if it rejoins with the end of other chromosome or if remains unattached. In case of a pair of homologous chromosomes if one chromosome has any structural change and other one is normal we customarily call it a structural hybrid.

Abstract

This review presents an idea on the botanical description, medicinal properties and traditional usage of wild, edible and aromatic plant (Nymphaea alba) in the human nutrition. Nymphaea alba Lin, also known as the White Water lily, White Lotus, or Nenuphar is an aquatic flowering plant of the family Nymphaeaceae. Nymphaea is a weed in India and its production pretty much as good as water chest nut and Nelumbo nucifera. Its rhizome is rich in tannic acid, gallic acid, alkaloids, sterols, flavonoids, glycosides, hydrolysable tannins and high-molecular-weight polyphenolic compounds. It is used as associate aphrodisiac, anodyne, antiscrophulatic, astringent, cardiotonic, demulcent, sedative and antiinflammatory. Further, it conjointly produces calming and sedative effects upon the nervous system, and is beneficial within the treatment of sleep disorder, anxiety and similar disorders. Moreover, the content of starch in the rhizome is said to be 40%. Extensive work has been carried out on agronomic and phenotypic properties for most plants, but relatively little study has been carried out on the properties which are of direct technical and economic interest to competitive food and nonfood industry. Non-conventional food resources and their value addition have attracted attention in the recent yearsfor their potential use as functional ingredients in food formulations, besides food they have also been used for non-food applications. Moreover, Plants provide the predominant ingredients of medicines in most medical traditions. So, there is tremendous potential for the profitable industrial use of these medicinal plants and exploring them for further use. Keywords: Non-conventional food resources, Nymphaea alba, Rhizome.

1. Introduction

The heritage of medicinal plants used in India has an ancient history. The epic of Ramayana witnessed Sanjivani Booti as life saving drug. Two important compendia on medicinal plants i.e., Charaka Samhita and Sushruta Samhita were published between 1000 BC and 600 BC. In these Ayurvedic literatures, uses of more than 1,200 plant drugs along with their action and specific therapeutic applications are mentioned. Charaka made 50 vargas (groups) of drugs while Sushruta made 38 ganas (groups) of drugs (Singh and Gautam, 1997). India, with its diverse agro-climate, harbors large plant-diversity. Eastern Himalayas comprising Darjeeling, Sikkim and adjacent Nepal as well as Bhutan hills are very rich in florastic diversity, several of which are endangered but economically useful medicinal plants with high demand in national as well as in international market (Manandhar, 1999). A great many of these wild Himalayan medicinal plants have found their way into modern bio-pharmaceuticals and bio-cosmetics in recent times (Rai et. al., 2000). One such species is Nepalese Kutki (Picrorhiza scrophulariiflora, Pennell) belongs to family Scrophulariaceae.

P. scrophulariiflora is better known by the name Nepali Kutki. The rhizome of this plant has been found to contain the chemicals like Kutkin, D-mannitol and vanillic acid (Yang, 1996). It is said to have effects on fever, malnutrition due to digestive disturbance, jaundice, diarrhoea and dysentery (Zhang et al., 1994). In India it is valued for their demonstrated value as an antibiotic. They are also used as an adulterant of, or as substitute for, Gentiana kurrooa. Properties that these two species share include the ability to stimulate appetite and gastric secretions (Jain, 1968). In Nepal rhizome of this species is also used as a cathartic, in case of dyspepsia, as a purgative as well as in the treatment of scorpion bites (Anon., 1993). Some of the important active photochemicals are listed in Table 1.

Abstract

In the present study, a novel work on comparison of physico-chemical characterization and bacterial diversity of wheat straw compost and vermicomposting has been initiated in the tropical region. Wheat straw compost shows lesser pH, EC, TDS, Organic Carbon, Total Nitrogen and Total Phosphorus than vermicompost whereas there was an increase in Total Nitrogen, Total Phosphorus and Electrical Conductivity and a drop in the pH, TDS and Organic Carbon of the vermicompost as the composting progressed from 0, 3, 10, 17, 24 and 31 days. Strains of Bacillus spp. and Thermoactinomycetes were screened from the wheat straw compost, which are ecologically important and have commercial potential for enzyme production. These strains were able to degrade cellulose, hemicellulose and lignin and exhibited cellulase activity. Enterobacter aerogenes, Micrococcus luteus and E.coli were isolated from the gut of Eudrilis eugeniae which help in the transformation of biodegradable waste materials into valuable compost.

Aim

To study the levelling instruments

To practice the simple leveling

Leveling

Leveling is a method of surveying used for determination of the difference of elevations or levels of various points on the surface of the earth. The elevation of a point is its vertical distance above or below a reference level, called datum. Most commonly used datum is the mean sea level (M.S.L). Leveling is required to determine the undulations of the earth’s surface for topographic mapping. Leveling is needed for the design of highways, railways, canals, sewers, etc. Leveling is essential for the layout of construction projects, locating the excavation levels and for the control of various elevations in buildings, bridges, dams etc. The results of the leveling can be used to determine the catchment area, volume of the reservoir and the area submerged by a reservoir.

ABSTRACT

The present experiment was conducted in order to develop a protocol for rapid in vitro propagation of pomegranate Cv. Mridula. Shoot tip and nodal segment explants selected from mature plant were cultured in MS medium supplemented with NAA and BAP in different concentration and combinations. To control phenolic browning, sub- culturing of cultures was under taken at an interval of first and third day after inoculation. The MS medium supplemented with NAA 0.4 mg/l + BAP 1.0 mg/l showed highest percentage of shoot differentiation with 77.77 per cent and 81.25 per cent response from shoot tip and nodal segment explant respectively. In the same media, earlier shoot initiation as well as more number of multiple shoots/culture were obtained. The shoots when elongated up to 2.5 - 3.0 cm length were transferred for rooting in the ½ strength MS media supplemented with auxins. There was no significant difference for root induction among the type of auxin used either NAA, IBA or both in combination. The concentration of auxins 0.5 mg/l was found to be optimum. Rooted plantlets after hardening in green house gave 49 per cent survival.

Abstract

Pollinators provide key services to both natural and agricultural ecosystems. Agricultural productivity depends, in part, on pollinator populations from adjacent semi natural habitats. Honey bees are the primary pollinators of mustard crop because it is highly attractive to bees and provides both nectar and pollen. Studies were conducted to assess the diversity and relative abundance of pollinators in mustard (Brassica juncea) of 2011-2012 at Apiary Garden, G.B Pant University of Agriculture & Technology, Pantnagar.A total of 19 insect visitors belonging to order Hymenoptera (15) and Diptera (4) were found to visit the mustard blossoms. Hymenopteran visitors belonged to six families namely Apidae (6), Scollidae (3), Xylocopidae (1), Halictidae (2), Magachilidae (1), Anthophoridae (1) and Sphecidae (1). Lepidopteran visitors belonged to families Pieridae (1). Besides this some Dipteran visitor belonged to families these were Syrphidae (3) and Muscidae (1) were observed on mustard flowers. From the family Apidae, honeybees (Apis mellifera, Apis dorsata, Apis cerana indica and Apis florea), Ceratina sexmaculata, Xylocopa iridipennis and stingless bee Tetragonula laeviceps family Apidae. Scolia (Discolia) binolata, Campsomeriella collaris and C. annulata of family Scollidae, the Alkali Bees (Nomiasp.) and Halictussp. of Halictidae, Leaf cutter bee (Megachile disjuncta) of Megachilidae, the digger bee (Anthophorasp.) of Anthophoridae and Sphex sp. of Sphecidae. Three species from family Syrphidae (Syrphus corollae, Episyrphus valtiatus and Eristalis tenax) and one species from Muscidae (Musca domestica) visited the mustard flowers. The abundance (percentage of insect/m2/2min.) of Hymenopterans were maximum (79.97 %) followed by the Dipterans (16.15 %) and others (3.73 %). In Hymenopterans, the honeybees (Apis bees) were observed maximum (57.55 %) followed by non Apis bees (21.06 %) and the scolid wasp (1.35 %).

Aim

To identify different parts of prismatic compass and to know their functions.

To practice of taking the angular measurement.

Compass survey principle

Compass surveying is a branch of surveying in which directions of survey lines are determined with a compass and the lengths of the lines are measured with a chain or tape. In practice, the compass is generally used to run a traverse. In compass surveying, a traverse consists of a series of straight lines connected together to form an open or closed polygon as shown in Fig.44.1. The points A, B, C, D and E defining the ends of the traverse lines are called traverse station or traverse points. The lengths of the traverse lines are measured with a chain or tape. At each traverse station, where the traverse lines meet, the angle is measured with a compass.

1. Introduction

Inflammation have been linked with pathogenesis of many diseases like Cancer, Atheriosclerosis, Neurodegenerative diseases, Diabetes Mellitus, Obesity, Arthritis, Cardiovascular diseases, Parkinson’s disease and other deadly diseases (Lee and Weinblatt, 2001). Inflammation can result to genetic defects and immunoregulation and mechanism defects which lead to tissue damage (Jones, 2006). Anti-inflammatory drug was serendipity discovered without thorough investigation and even not effective in term of controlling inflammation and now record several side effect just like other synthetic drugs, thus, safe biological sources are now been considered. Biological sources for active compounds that have medical importance are increase in recent time (Kaboli, 2001). Also, due to the residual side effects of synthetic compounds that form bulk of the materials used for the production of pharmaceutical products. Aspirin can cause stomach bleeding, acetaminophen can cause liver damage Cox-2 inhbitor Vioxx and Celebrex can cause heart problem and non-steroidal anti-inflammatory drugs (NSAID’s) was reported to contribute to numerous death (Clegg et al., 2006; Wolf et al., 1999; Sing, 1998).

Abstract

The experimental results indicated that the treatments, cultivars and root stocks had expressed significant influence on growth, fruiting, fruit quality and leaf nutrient status of apple. The highest trunk girth (21.22 cm), shoot extension growth (22.77 cm), tree height (223.60 cm) and tree spread (184.20 cm) were recorded under the 2/3 dose of NPK  fertigation during 2003 and 2004.  The maximum yield (12.82 kg/tree), productivity (14.24 MT/ha) and fruit set (64.84%) were recorded in fertigation treatment of 2/3 dose of NPK which was significantly higher than other treatments during 2004 and similar trend was observed in the year 2003.

ABSTRACT

Studies on the impact of bio-fertilizers with levels of NPK on bulb yield, dry matter production, nutrient uptake and cost: benefit ratio in onion (cv. Bellary Red) were conducted in medium black soils during kharif and rabi seasons of 1999 and 2000 both under irrigated and rainfed conditions at the Agricultural Research Station, Hiriyur located under Central Dry Zone of Karnataka. The treatments were; T₁-Control, T₂-Azotobacter, T₃-Azotobacter+75% N+PK, T₄-Azotobacter +100%N+PK, T₅-Azospirillum, T₆-Azospirillum+75% N+PK, T₇-Azospirillum+100%N+PK, T₈-VAM, T₉-VAM 75% P+NK, T₁₀- VAM+100%P+NK, T₁₁ ? recommended NPK(125:50:125 kgha-1) and T₁₂-75% recommended NPK. The experiments were laid out in RBD in three replications.

The bio-fertilizers Azospirillum brasilence (500g ha-1) and Azotobacter vinelandii(500g ha-1) were applied to seedlings at transplanting separately by dipping the roots in the slurry for 15 minutes. The VAM fungi - Glomus mossae was applied to soil @ 1 kilogram per square meter area of nursery bed. The recommended dose of FYM @ 25 t ha-1 was applied to all the treatments as basal dose.

The results of the investigations revealed that the plants provided with Azospirillum + 100% N+PK (T₇) produced highest bulb yield (250.29;339.02;232.98 q/ha), highest total dry matter production (7053.96;8992.78;6287.03 kg/ha), maximum uptake of N, P a nd K ( 1 5 7 . 8 8 : 7 3 . 5 6 ; 7 0 . 4 6 N PK k g / ha ) , ( 2 0 6 . 8 6 : 9 6 . 2 5 : 9 1 . 1 0 N PK k g / ha ) , (131.81:50.25:71.24 NPK kg/ha) and also the maximum cost:benefit ratio of 4.00 (1:400), 5.42 (1:5.42), 3.94 (1:3.94) under irrigated condition during kharif and rabi seasons and under rainfed situation during kharif season respectively.

Thus, among all the treatments, application of Azospirillum + 100% N + PK (Azospirillum + 125:50:125 NPK kg/ha) was found to be most remunerative considering the nutrient uptake, bulb yield and total dry matter production and cost:benefit ratio, which gave the highest returns. This level can be followed for Bellary Red onion irrespective of seasons both under irrigated and rainfed conditions in the Central Dry Zone of Karnataka.

ABSTRACT

Basic understanding of plant cell proliferation and differentiation is essential for applying modern techniques of genetic transformation. The lack of understanding about the physiological and molecular mechanisms underlying in vitro morphogenesis, together with the non-availability of reliable morphogenetic markers, is one of the most serious constraints for application of gene transfer technology to plant improvement. Plant tissue culture has therefore remained an empirical science. In recent years, concerted efforts are being made to understand the molecular control of cell differentiation. In light of this, present work was carried out to study the role of CKI1 (cytokinin independent 1) gene, one of the genes implicated in shoot regeneration, by transforming the tomato cotyledons through Agrobacterium mediated transformation with two different gene constructs one with CKI 1 gene and another without CKI1 gene. In both the constructs, nptII gene was used as a selectable marker. Transformation of tomato cotyledon explants with CKI 1 gene resulted in higher regeneration of putative transformant s (8.0%) as compared to transformation of explants without CKI1 gene (2.1%). The results show that CKI1 gene has a role in increasing the regeneration frequency in tomato.

1. INTRODUCTION

The medicinal plants have been used by humans from the pre-historical times. Traditional medicine based on herbal remedies has always played a key role in the health systems of many countries. In India, the native people are exploiting a variety of herbals for effective curing of various ailments. Medicinal plants are widely used by all sections of the population and country is richly endowed with a wide variety of plants of medicinal value, which represents the great national resource (Alok, 1991).

It is estimated that at least 70 percent of population relay on herbal medicines for primary health care in our country (Holley and Williams, 1996). In India, different classical medicinal systems such as Ayurveda, Siddha and Unani are being practiced in the country and in addition to innumerable local folk medicinal traditions exist. More than 8000 species of wild plants are known to be used in India for the treatment of various health problems (Ved et al., 2000). This rich medicinal wealth is mainly distributed in two biodiversity hotspots that are Eastern Himalayas and Western Ghats. Numerous studies have pointed out that many drugs that are used in commerce have come from folk-use and use of plants by indigenous cultures (Anon, 1994). Medicinal plants form a heterogeneous group in growth, habit, distribution, reproduction, phenology and their ecological requirements.

Seven different parents viz. July Elberta, Alton, J.H. Hale, Kanto-5, Saharanpuri, Quetta as female and Kateroo as male were used in the present crosses.  The crosses were made in the year 1997 and 76 hybrid seedlings under different crosses were raised  for these studies. The variability in respect of chemical characters, the mean values for titratable acidity for each cross varied between 0.50 to 0.75%, TSS 11.53 to 12.90oB,  reducing sugars from 2.33 to 2.88%, non-reducing sugars from 6.27 to 6.83%, total sugars from 9.24 to 10.05% and TSS/acid ratio between 14.47 to 23.90. The coefficient of variability varied 11.07 to 31.55% for titratable acidity, 0.00 to 23.02% for TSS, 5.24  to 18.53% for reducing sugars, 2.09 to 15.14% for non-reducing sugars, 0.00 to 6.80% for total sugars and 18.23 to 156.51% for TSS/acid ratio in these crosses.

Abstract

Microencapsulation has found great applications in food business. However, the technology remains aloof from being fully exploited. Microcapsules offer food processors a way to shield sensitive food ingredients, mask or preserve flavours and aromas and conversion of volatile food components into easy-handled solid ingredients (like powders, capsules etc). A number of naturally occurring and synthetic polymeric materials have been identified so far that possess the entrapping property and are categorised as GRAS materials. Numerous techniques have been developed for using these entrapping materials to encapsulate the sensitive food ingredients. Controlled release of the food ingredients at proper place and right time could be therefore a key practicality that may be provided by microencapsulation. With strictly fine-tuned and stabilized release characteristic, this method adds worth to the merchandise. The areas of interest in this field include the development of alternative and inexpensive polymers that may be considered natural or mimic the properties of natural polymeric materials, like Gum Arabic, Gellan Gum, Gum Karaya, Gaur Gum and Gum Acacia. Limitations in many of the encapsulation techniques have occurred due to high value of raw materials and production. This review is effectively committed to the, properties of encapsulating agents along with the emphasis on different techniques used for encapsulation in the varied fields like food technology, pharmaceutical, commercial engineering and biotechnology.

The concentration of a true solution refers to the amount of solute present in a given quantity of solvent or solution. It is an important property because it determines the solution’s behavior in chemical reactions, its physical proper ties (such as boiling and freezing points), and its utility in various applications. Concentration can be expressed in several ways, depending on the context and the precision required.

Methods to Express Concentration of a True Solution

1. Molarity (M)

• Definition: Molarity is the number of moles of solute dissolved in one liter (1,000 mL) of solution.

6.1. Data Interpretation and Visualization of West Bengal

Any kind of production management system or decision-making process is being organised in social ecology. No variable cannot behave discrete or free without having any kind of influence as well as impact from the vary operating ecosystem. That is how it is imperative to know and visualize the basic features in terms of its distributive characters. The distribution of features in variables through this networking and interactions ultimately contribute to a holistic visualization of social ecologization under study.

Table 6.1.1 represents the distribution of variables in terms of range i.e. maximum and minimum values, mean, standard deviation and coefficient of variation for Terai Zone, Old Alluvial Zone and New Alluvial Zone of West Bengal.

The average age (x1) of the respondent stands at 49.02. It denotes that so far as responsibility of agriculture and age base livelihood runs at the population so far as the respondent under study is peaks are at the hands of farmers approaching or passing through old ages. On the contrary the absence of young population or withdrawal of young age farmers from agriculture have got a serious implecation near and far. The cv value runs at 25.78 per cent to indicate that the distribution of variable is highly consistant.

The average of functional education (x2) of the respondent stands at 8.20.The variable education charecterization the social ecology speaks that the most of the respondents are having mid level school education.So, this has got spil over effect on the function and operation of other variables i.e. precisely the perception variables.The cv value stands at 43.69 per cent that’s good enough to infer that the distribution of the variable is highly consistent.

Objectives
• Understand the concept of antecedents in grammar and their role in sentence structure.
• Identify different types of antecedents and their functions in sentences.
• Recognize how antecedents relate to pronouns and other grammatical elements.
• Learn how to use antecedents correctly to avoid ambiguity and improve clarity in writing.
• Analyze examples of antecedents in various contexts to enhance comprehension and application.
Introduction
In grammar, an antecedent is a word or phrase that a pronoun refers back to in a sentence.
Antecedents are usually nouns or noun phrases that provide clarity about which person, place, thing, or idea is being discussed. The correct use of antecedents ensures that sentences are clear and that pronouns have specific references.

CHI- SQUARE TEST (χ₂ TEST)

The chi square test is used to determine if the two attributes are independent of each other. Chi square is a measure to evaluate the difference between observed frequencies and expected frequencies to examine whether the difference so obtained is due to a chance factor or due to sampling error.

In a contingency table if each attribute is divided into two classes it is known as 2×2 contingency table. When one attribute is divided into two classes and another into r or c resultant contingency table is known as r×2 or 2×c contingency table. Here, r denotes the number of rows and c the number of columns. For such data, the statistical hypothesis under test is that the two attribute are independent of one another. To test this hypothesis we use the test statistic

1. What are Agri-enterprises?
• Agri-enterprises encompass businesses involved in any stage of the agricultural value chain, beyond just primary production (farming). This includes:
• Input Suppliers: Companies that provide seeds, fertilizers, pesticides, machinery, animal feed, etc., to farmers.
• Processors: Businesses that transform raw agricultural products into more refined or consumer-ready goods (e.g., milling grains, processing meat, canning fruits and vegetables, dairy processing).
• Manufacturers: Companies that use agricultural products as ingredients in other manufactured goods (e.g., food and beverage companies, textile manufacturers using cotton).
• Distributors and Retailers: Businesses that move agricultural products from producers/processors to consumers (e.g., wholesalers, supermarkets, restaurants).
• Service Providers: Companies that provide services to support the agricultural sector (e.g., transportation, storage, marketing, finance, insurance, agricultural consulting, technology providers)
2. The Value Chain Concept
The value chain describes the full range of activities required to bring a product or service from conception through the different phases of production (involving a combination of physical transformation and the input of various producer services), delivery to final consumers, and final disposal after use..

Studying agri-enterprises involved in various industry sectors through Value Chain Models can provide insights into how agricultural products are grown, processed, marketed, and sold. Understanding these value chains is crucial for enhancing efficiency, increasing profitability, and improving sustainability in agricultural sectors. Below, we will discuss the concept of value chain models, how to analyzeagri-enterprises within these models, and provide examples.
Key Components of Value Chain Models
1. Primary Production: This involves the cultivation of crops or livestock production. It encompasses all activities related to planting, growing, harvesting, and maintaining the quality of the produce.
2. Processing: This stage includes transforming raw agricultural products into consumable goods or other forms suitable for market distribution. Processing can take many forms, from simple packaging to complex food manufacturing.
3. Distribution: This aspect covers the logistics of getting agricultural products from farms or processing plants to consumers. It includes transportation, warehousing, and inventory management.
4. Marketing and Sales: Effective marketing strategies are necessary for reaching consumers, which may involve branding, advertising, pricing strategies, and sales channels, including retail and online platforms.
5. Consumption: This is the final stage where consumers purchase and utilize the agricultural products. Understanding consumer behavior can influence the entire value chain.

The study of agri-enterprises involved in service sectors within the context of value chain models is a crucial area for understanding and improving the efficiency, profitability, and sustainability of agricultural systems. Here’s a breakdown of key aspects:
1. Understanding Agri-Enterprise in Service Sectors
• Definition: Agri-enterprises in service sectors are businesses that provide services that support and enhance agricultural production, processing, distribution, and marketing. These services are integral parts of the agricultural value chain.
• Examples of Service Sector Agri-Enterprises
º Input Suppliers: Seed companies, fertilizer distributors, pesticide applicators, irrigation equipment providers.
º Financial Services: Microfinance institutions providing agricultural loans, crop insurance providers.
º Extension Services: Agricultural consultants, agronomists offering advice on farming practices, soil testing labs.
º Logistics and Transportation: Trucking companies transporting produce, cold storage facilities, warehousing services.
º Processing and Packaging: Food processing plants, packaging material suppliers, labeling services.

Introduction

Environmental problems have come to the forefront as one of the most important issues in transport policy. For a number of pollutants the road transport sector is one of the most significant contributors to environmental pollution. Vehicular emissions have been identified as one of the major contributors in deteriorating air quality in the urban centers. The problem has further been compounded by the concentration of large number of vehicles and comparatively high motor vehicle/population ratios in these cities. Substantial SPM, RSPM CO₂ and No_x are emitted. The problem of air pollution has assumed serious proportion in some of the major metropolitan cities of India. Therefore, CPCB has 296 monitoring stations all over India covering major cities.

The air pollution situation in most of the cities is still far from satisfactory. In India the major air pollution reason is automotive smoke and smoke from industries. New channels are also publishing pollution levels in selected metropolitan cities. The most polluted city in Asia is Pune. The SPM and RSPM levels are displayed at various squares to create awareness among the masses.

Smaller cities like Nanded, Parbhani and Yavatmal are not covered under National Ambient Air Quality Monitoring (NAAQM) scheme of Central Pollution Control Board (CPCB). The National Ambient Air Quality Standards for suspended particulate matters (SPM) are based on gravimetric measurement. Standards for Respirable suspended particulate matters (RSPM) are also based on gravimetric measurement. The development in terms of number of vehicles and building construction has also reached at the doors of these cities and towns. Nanded city having population of 5.5 lakhs has total number of Auto rickshaws more than 5,000. In the present study, Nanded city has been selected to check particulate matters and gaseous pollutants. Since, the city is one of the important Pilgrimage and commercial centre.

Real time weather data at different time intervals is very important for the crop weather studies, but through the agro-meteorological observatories such real time weather data are generally not collected. The acquisition of agro-meteorological data through conventional observatories requires services of trained personnel to collect, compile and creation of weather data base. With the advances in technology, weather observations are automatically recorded, stored and can be transmitted to the remote place with the help of Automatic Weather Station (AWS).

Aim

To study the different materials used for chain survey

Theory

Chain surveying is the method of land surveying in which only linear measurements are made. This method of surveying quit simple and it requires only a chain, a tape, few ranging rods and few arrows. It is used for securing data for exact description, marking the boundaries of land and preparing the maps of the area to show various details. The term details mean a natural or man-made feature at the ground surface.

Check dams are small water control structures designed to slow down water flow and limit erosion, particularly in hilly or mountainous regions where other flow regulation methods may not be feasible. The suitability of a site for check dam construction depends on factors such as terrain gradient, soil characteristics, and the potential for enhancing groundwater recharge. Locations with flat or mildly sloped land and stable soil conditions for a solid foundation are generally ideal. These dams function as multi-purpose solutions, playing a vital role in water regulation and soil preservation. Their importance extends across hydrological, ecological, and social aspects, making them key components in sustainable infrastructure efforts.
WHAT ARE CHECK DAMS?
Check dams are small structures constructed across shallow rivers or streams to harvest water. These barriers help retain excess monsoon water in a small catchment behind them. The pressure buildup in this area pushes water into the ground, aiding groundwater recharge. This stored water, both on the surface and below, is primarily used for irrigation during and after the monsoon but can also serve domestic and livestock needs. They vary in size and are made from materials such as clay, stone, or cement. Earthen check dams can be easily built by farmers, whereas masonry and RCC (Reinforced Cement Concrete) dams require skilled labor and higher costs. Earthen structures typically do not allow overflow, unlike RCC and masonry dams which include spillways for excess water.
Construction of a Check Dam
Used as an engineering solution to prevent soil erosion in vulnerable areas, check dams reduce water speed, trap sediments, and sometimes only consist of an embankment. Initially, a water body forms behind the structure, which gradually fills with silt.
