Networks – Introduction, origin and widely used networks
Network is a technique used for planning and scheduling of large projects in the fields of construction, maintenance, fabrication, purchasing, computer system instantiation, research and development planning etc. There is multitude of operations research situations that can be modelled and solved as network. Some recent surveys reports that as much as 70% of the real-world mathematical programming problems can be represented by network related models. Network analysis is known by many names PERT (Programme Evaluation and Review Technique), CPM (Critical Path Method), PEP (Programme Evaluation Procedure), LCES (Least Cost Estimating and Scheduling), SCANS (Scheduling and Control by Automated Network System), etc.
It is a graphical representation of logical and sequentially connected activities and events of a project. Network is also called arrow diagram. PERT (Programme Evolution Review Technique) and (Critical Path Method) are the two most widely applied techniques.

R - enamel can : The acid resistant, gold coloured enamel treated can are called R enamel cans. It is used for canning of acidic food which have soluble colouring pigments.
R factor : It is a group of genes present in some bacteria that provide a basis for resistance to antibiotics and can be transferred from cell to cell by conjugation.
R value : R value is a measure of resistance to the flow of heat through a given thickness of a material (insulation) with higher numbers indicating better insulating properties.

India over several millenniums has been the treasure land of biological wealth, intellectual knowledge and spiritual wisdom. During both pre and post Vedic periods, arts, science and technology had flourished well in various fields. Indian agriculture to some extent is much traditional and dates back to about 10,000 years. India with its traditional crop varieties and crop production technologies was able to feed its population and also exporting some selected produces to other continents. All the Indian villages had been the self sufficient, self sustained and self reliant units. The development of modern agricultural production was achieved by creating large scale specialized farm production units, increased mechanization and use of chemical inputs.

Introduction

Fisheries is a fast-growing and important sector for providing nutritional security and supporting livelihood in many countries. The global fish production currently stands at 179.9mt with a contribution of 112mt from marine and 65.43mt from inland sector (FAO, 2022). India is no exception to this; fisheries provide nutritious food and livelihood to millions. Our country ranks second in the world next to China in total fish production and aquaculture production. It contributes 14.7% to world fish production. Currently, fisheries is one of the fastest growing food production sectors in India with annual growth rate of 10.34% and annual production of 16.25mt. It contributes 1.1% to the national GDP, 6.7% to the agricultural GDP and provide livelihood to about 14 million. The inland fisheries and aquaculture contribute 12.12mt to the total fish production (DAHDF, 2023).

Fish production in India has gradually and definitively shifted from marine to inland fish production due to the rapid growth of the inland fisheries sector. Aquaculture development, including refinement of production protocols, introduction of new species and culture system, concomitant growth in input supply (seed, feed, medicine and chemicals), emphasis on education, training and skill development, intensive network of extension system and policy support has led to a notable increase of inland aquaculture, which currently contributes to more than 70% of inland fish production of the country. In addition, high profits in aquaculture coupled with limited water and land resources have led to system intensification using high rearing density and high protein feeds to boost productivity in closed or semi-closed systems (Zaki et al., 2020). In order to reduce mounting pressure on land resources, vis-a-vis to meet the country’s fish demand, the production must come from comparatively under-exploited fisheries resources through technological interventions. India has abundant and diverse inland aquatic resources with huge fisheries potential (Sharma et al., 2010). Reservoirs are the most important and potential inland water resources (3.5mha) that can play a major role in boosting fish production in the country. However, the recent scrutiny shows the average fish yield from this mega resource is 110kgha-1 (Sarkar et al., 2018).

Introduction

Water is a vital component of agricultural production. It is essential to maximise both yield and quality. Water has to be applied in the right amounts at the right time in order to achieve the right crop result. At the same time, the application of water should avoid waste of a valuable resource and be in sympathy with the environment as a whole. Understanding, measuring and assessing how water f lows around the farm, and recognising how farming practices affect f lows, will help farmers to manage water efficiently and reduce pollution risks. Land management and advanced technologies can help maximise the “crop per drop” that farmers produce worldwide. Water used in irrigation accounts for 90% of agricultural water demand. Improving irrigation systems is therefore crucial to making contributions to water savings in agriculture. In any agricultural production system the promotion of good agricultural practices and product stewardship is fundamental for sustainable agriculture. Industry is part of various multi stakeholder partnership initiatives that support efforts to protect water quality. These include reducing soil erosion, avoiding pesticide run-off and maintaining wildlife habitats as part of a holistic farm or land management approach.

1. Introduction

Present day botanic gardens have their origins from medicinal plant gardens established during the middle of the 16^th century meant for the cultivation of medicinal plants. Therefore, the roots of botany are traced from the medicine. The modern botanic gardens are considered as an ordered collection of plants, assembled primarily for scientific and educative purposes. They serve as the living repositories and offer excellent opportunities for ex-situ conservation, taxonomy, and studies on various other botanical aspects as mentioned below:

Measurement of soil moisture content is one of the most routinely done soil characterization. Knowledge of soil moisture is essential to understand the behaviour of soil as a medium for plant growth. Moreover, this property of soil helps to explain other processes of the soil. There are several methods of measuring soil moisture content. The most commonly used methods are gravimetric and tensiometric. The standard gravimetric method is quite accurate and simple but is time consuming, cumbersome and destructive. Furthermore, due to relatively small soil samples that are taken, the variability between replicates is great.

Gravimetric Method

Equipment needed includes zip-loc bags or aluminium moisture boxes and soil sampling tools. Soil sampling tools can be a soil probe, auger, or even a post-hole digger. Balance and scale should have accuracy to 0.1 gram. Proper sampling of the field is important to obtain a representative sample of the field. The soil sample should be collected from the field at a minimum of three locations, and the sample locations chosen should represent the entire field. Sampling from the small areas of low spots or ridges that do not represent majority of the field should be avoided. If there are major changes in soil classification within a field, the field should be divided into sub-sites and samples are collected accordingly.

Introduction
The richness of a country can be measured by its biological diversity. It is essential to both human existence and financial security. The most basic concept of biodiversity is expressed by the diversity of creatures. Biodiversity is represented by the supplies of food, clothing, shelter, and medicines provided by plants; by the sources of food, assistance, wild life, and human resource efficiency provided by animals; and by the patterns of variation seen in the microbiological world. More than 20,000 kinds of ants, 3,000,000 species of beetles, 28,000 species of fish, and almost 20,000 species of orchids would be hard for the average person to believe.
Definitions
• The collection and interplay of genes, species, and ecological diversity in a specific location and time is known as biodiversity. Different genes, species, habitats, and their relative abundance are all included in the phrase biodiversity.
• The portion of nature known as biodiversity comprises the genetic variations between individuals of the same species as well as the variety and richness of all plant and animal species at various spatial dimensions, such as a region, a nation, and the entire planet.
• “The diversity of life, which encompasses ecosystem or community diversity, species diversity, and genetic diversity, and includes the entire range of variety and variability within and among living organisms and the ecological complexes in which they occur,” is another definition for it.

Pulse production in NE states in still too low as compared to whole India. However, there is very good potentialfor enhancing pulse producity in the region and contribute to food grain production of the country. In view of these constraints, prospects for increasing pulse production from this region have been visualized.

Pulse production scenario

Despite immense importance of pulses in humanand animal nutrition, the share of north-easternregion inthe total pulse areofIndiaistoolow (0.76%)andthisregion contributesonly176.44 thousandtons(0.99%) in the all Indiapulse production (Table 1). WithinNE Region, mostof the pulsearea isoccupied by Assam and 47% of total N.E. Region’s pulse production is contributed by this state alone. After Assam, Nagaland and Tripura are major pulse growing states with 33.5 and 14.5 thousand hectares of area and 36.46and 24.20thousandtons ofproduction, respectively. In Meghalaya, pulseswere grownon4 thousandhaarea and4.2 thousand tonnesof pulses wereharvested in 2010-11. Thefactthat theaverage pulse productivity of NE region (883.0kg/ha)is much higher thanthatof whole India (689kg/ha) offers opportunityfor increasingarea and production of pulses in the region.

The production of premium fish feed involves using specialized equipment across various stages—grinding, mixing, conditioning, pelleting or extruding, drying, cooling, and packaging. Each machine contributes to achieving consistency, efficiency, and high-quality standards in aquafeed manufacturing. Equipment selection depends on production scale, feed type (floating or sinking), targeted aquatic species, and financial considerations. • Hammer Mill or Grinder: The grinding phase reduces raw materials into smaller particles using a hammer mill, which operates with rotating hammers to crush substances like grains and oil cakes. The screen size can be changed to control particle fineness, which is important for effective mixing and digestion. • Mixer :Mixers ensure even distribution of ingredients. Two types are common: • Horizontal Mixers: High mixing efficiency and ideal for large volumes. • Vertical Mixers: Cost-effective, better suited to small-scale operations. Micro-ingredient dispensers and dosing units may be attached for accurate inclusion of additives and micronutrients

Components of Project Finance
1. Capital Structure Determination: Deciding on the mix of debt, equity, and other sources of financing that will be used to fund the project. The goal is to structure the capital in a way that minimizes costs, maximizes returns, and balances risk. Here’s an elaborate breakdown of the steps involved in capital structure determination:
Understanding Financing Options
• Debt Financing: Borrowing funds that must be repaid with interest. Common sources include bank loans, bonds, and credit lines. Debt financing is often preferred for its tax benefits (interest payments are tax-deductible) and lower cost compared to equity. • Equity Financing: Raising capital by selling shares of the project to investors. This does not require repayment but dilutes ownership. Equity financing is useful for sharing risk and avoiding the burden of debt repayments.
• Hybrid Instruments: Combining features of both debt and equity, such as convertible bonds or preferred shares. These can provide flexibility and attract a broader range of investors.
• Other Sources: Grants, subsidies, and public-private partnerships (PPPs) can also contribute to project financing without adding to debt or diluting equity.

Among thirty major cropping systems in the country, which contribute significantly to the national food basket, the majority are cereal-based. In fact, continuous cropping of cereal-based systems during last three decades has resulted in second generation problems and the sustainability of these systems is under threat. The major challenge is to produce more from each unit of land on the one hand and to sustain soil health on the other. The depletion of soil fertility by the intensive cereal-cereal production systems is considered to be a major cause of the yield decline. For example, a rice-wheat cropping system (RWCS) yielding 7 t/ha of paddy and 4 t/ha of wheat removes 315 kg nitrogen (N)/ ha, 28 kg phosphorus (P)/ ha and 333 kg potassium (K)/ ha, and significant amounts of micro-nutrients (Hegde and Dwivedi, 1992). These off-takes often exceed fertiliser input in many Indian states. Refinement of nutrient management strategies would help maintain the crop productivity and soil fertility, but other rotational strategies could also help especially in situations where greater fertiliser use may be uneconomic or environmentally unacceptable. Legume crops fix atmospheric N and enrich soil fertility, and could help to sustain the long-term productivity of cereal-based cropping systems. Depending on the soil and ecological stresses, a cropping system can be diversified using legumes under different mode. Results from the All-India Coordinated Project on Integrated Farming Systems (AICRP-IFS) of Indian Council of Agricultural Research show consistently better productivity with inclusion of legumes in cropping systems. The benefits of legumes in rotation are not solely due to biological nitrogen fixation but also because it increased nutrient availability, improved soil structure, reduced disease incidence and increased mycorhyizal colonization (Wani et al., 1995). Inclusion of pulses as intercrops in sequential as well as intercropping systems would not only make the country self reliant but also help in improving the soil health. Series of experiments are being conducted under (AICRP-IFS) and elsewhere in the country to identify need based cropping systems for different agro-climatic zones of India. The pre-dominent cropping systems involving legumes as a strategy for nutrient management through different approaches are being discussed here for ready reference of researchers, planners and extension workers.

Greek scientist Theophrastus (300 BC) advocated legume rotation. As early as 1750 AD it was known that plants require Nitre. Louis Pasteure in 1860 AD stated the possibility of atmospheric nitrogen fixation by microorganisms. Hellriegel and Willfarth (1886) strengthened the views of Louis Pasteure by his observations on the irratic behaviour of legumes to nitrate nutrition. Beizerink (1890) isolated the organism involved in nitrogen fixation. The systematic field experiments conducted at Rothemstead experimental station showed that the plants respond to inorganic nitrogen.

ROLES OF NITROGEN IN CROPS

Plants contain 1-5 per cent nitrogen by weight. It is a structural component of chlorophyll, aminoacids and proteins. Plant proteins contain 16 per cent nitrogen (6.25 × %N = protein). Plants are dependent on protein for their propagation. Cereals possess a threshold protein level below which grain will not form.

ABSTRACT

This paper provides an overview on existing IP protection and registration systems of India and adds information culled from publicly available sources pertaining to modernization efforts of Government of India towards establishment of foolproof IP protection in accordance with international treaties, conventions and bilateral and multilateral agreements.

In the past, focus on implementing plant protection measures was given to cereals, largely because of their central role in food security, however, recent shortages in legumes has warranted an all out attention on edible pulses. For more than four decades, the concept of integrated pest management (IPM) - which combines a range of controls, including conserving natural predators, using pest resistant crop varieties, intercropping and rotation, with judicious use of pesticides -has struggled to gain ground against conventional agricultural ideology and practices. But it is now increasingly challenging the methods of high-input agriculture and policies arising with implementation of General Agreement forTrade andTariffs (GATT) & World Trade Organization (WTO) that cannot be ignored. In fact, a major factor responsible for sustaining soil productivity in this country has been the highly diversified nature of the cropping patterns which either include a pulse crop or a legume crop as one of the components. India is the largest producer of pulses in the world with 25% share in the global production. While chickpea is the topper among pulses occupying 39% of pulse area, pigeon pea is next with 21% area. The major pulse producing states are Maharashtra (20%), Madhya Pradesh (17%), Rajasthan (11%), Uttar Pradesh (11%) andAndhra Pradesh (11%) together accountingfor 70% of thetotal production of 14.76 m.t from an area of 23.63 m ha (www.agricoop.nic.in, 2007-08). In general, the pulse production is not keeping pace with the domestic requirements, hence, the country has to import 1.5-2.8 m.t per year, which is a matter of concern. Keeping this in view, the 1PM programme covers the two important pulse crops viz., chickpea and pigeon pea, across different cropping systems which will take care of changing scenario emerging out of climatic changes as well as cropping patterns. The present strategy, which is based on a holistic approach and changing ecosystem, will help in increasing production through reduction in pest infestation that would eventually reduce the need for the import of these two vital commodities.

We live in a knowledge economy, where ideas generated by talented people and the inventions they make are the new currency. Research and innovation are now seen as the key differentiating factors determining the market value of a product or service. The emphasis today has graduated from cost arbitrage and quality deliverables to Intellectual property (IP) creation and research and development. Intellectual or Intangible property is the creation of human mind. An intellectual property under protection by law is intellectual property right (IPR). Intellectual property is an important business asset giving significant competitive advantages. Intellectual properties are protected by giving time bound restriction to inventor, owner, author, originator, or plant breeder to use, sell, share, or distribute intellectual asset. These are exclusive rights to the owner and give ability for a lawsuit against others for infringement of IP owner. It is also a marketable asset, which can be licensed out to a third party bringing income to the business in the form of license payments and royalties. Intellectual property rights are legal rights, which result from intellectual activity in the industrial, scientific, literary and artistic fields. These rights give statutory expression to the moral and economic rights of creators in their creations. Intellectual property rights safeguard the creators and other producers of intellectual goods and services by granting them certain time-limited rights to control the use made of those productions. These rights also promote creativity, dissemination, application of their results and encourage fair-trading, which contributes to economic and social development.

Pulse legumes are considered to be the best choice for intensification of predominant cereal-based systems. The studies conducted in different agro-climatic zones under AICRP on cropping systems have revealed that the productivity of existing cropping-systems can be enhanced by the inclusion of legumes during summer or as catch crop, or in intercropping systems (Gangwar et al., 2009). Further, these food legumes also serve as a feed crop in many farming systems and fetch higher prices compared to cereals and are increasingly being grown to supplement farmers’ incomes (Gouda et al., 1999). Although pulse legumes have many desirable characteristics in terms of increasing system’s productivity, raising nutritional standards and environmental benefits, in most countries of the world they are considered secondary crops. Globally, the harvested area under pulse crops is about one-tenth of the harvested area under all cereal crops. In view of the important and diverse role played by pulses in the farming systems and in the diets of the poor population, this chapter presents the global trade scenario in pulses followed by pulses production and trade opportunities in India. An attempt is also made to highlight the major concerns and to meet the future challenges in production and trade of pulses in India.

1. pH Meter

pH meter/electrode systems are the most common method of measuring pH in the biology laboratory. Although more expensive and more complicated to use than chemical indicators, pH meters provide greater accuracy, sensitivity, and flexibility. When used properly, pH meters can measure the pH of a solution to the nearest 0.1 pH unit or better, and they can be used with a variety of samples.

2. UV Spectrophotometer

Perhaps there is no other technique except UV-visible spectroscopy, which has been so extensively employed and has such a profound impact on progress in biochemical investigations. UV-visible spectroscopy has undoubtedly become an indispensable tool and is routinely used for identification and quantitative estimation of most of the biomolecules. Besides other applications, most of the enzyme assays and the screening of biomolecules recovered in different fractions by separation processes such as column chromatography, density gradient centrifugation etc, rely heavily on spectrophotometer or colorimetric technique.
