Since mouth pipetting of liquid reagents in a laboratory is not advisable, different tools are needed for safe, easier, and precise dispensing of liquid reagents. This chapter is devoted to make you aware of the tools like vacupette and micropipette which can be used for the handling of liquid reagents in a safe and precise way.

Vacupette

Glass pipettes have been traditionally used by sucking liquid solvent/solution directly using mouth. For safety reasons, mouth pipetting is no longer permitted in a laboratory. Hence, to fill a pipette vacupette is used by placing it on the top of glass or plastic pipette. It acts as a device to create vacuum for filling reagent in the pipette as well as for releasing the reagent with mechanical regulation on the flow out of the liquid. Vacupette can be of different types.

1. Rubber Bulb Vacupette

Rubber bulb vacupette is often used to transfer (pump up and discharge) liquid using a pipette when a larger quantity of chemicals is to be transferred. Small/tiny rubber bulb is attached to glass/plastic pipette for drawing little amount of reagents. Small vacupette is used to precisely discharge smaller volume/ drops.

Handling of Vacupette

• Insert the top of a pipette in the bottom of the rubber bulb vacupette (Figure 6.1).

• Remove air from the pipette by squeezing valve “A” at the top of the vacupette while simultaneously squeezing the rubber bulb. The amount of air released depends on the size of the rubber bulb.

Introduction

India is known to possess a significant demographic dividend due to its large and growing population where the female population is estimated to be 586.5 million or above currently. This population is characterized by vast regional and cultural differences that create difference in terms of region and culture due to which any kind of generalization is not possible. Women play a crucial role in the growth of the economy and over the years, they had made a substantial impact and achieved status across different sectors both within the country and overseas. Women is a part of workforce but still there is a large population of women both in rural and urban areas that has dreams, but lack the opportunities to realize those dreams and take up their roles other than the household ones. In this regard, it is essential for to promote skill development and women empowerment. In order to upgrade employability and other skills among women, there is need to reduce the unemployment, demographic dividend, cultural and regional barriers and bridge the gap between talent and industry by various innovative methods.

Proactive involvement of society is essential to attain the sustainable development and bring the desired change in the society. Women in economically disadvantaged areas lack opportunities for employment and for self-employment due to various causes and sometimes women in need are on the look-out for affordable vocational courses that is not only of interest to them but also enables them to enhance their employability. Women from these areas can be equipped with the skills they need to increase their employability so that they can access meaningful and sustainable employment, and self employment through entrepreneurship. UNICEF is also assisting women to build stronger links with the private sectors so that they have sustainable market access for their artisanal goods including those who are running home based business.

6.1 Scenario in precision farming

• India’s population is around 1366 million by 2020 which requires food grain production of 350 million tones.

• Considering the current food grain production levels, India needs to raise food grain production levels by not less than 4.00 per cent per year. As the availability of land has decreased, application of fertilizers and pesticides become necessary to increase food production.Indiscriminate use of inputs coupled with improper management practices over a long period has resulted in decline in soil productivity.

• Agriculture production system is outcome of interaction of various agro inputs. Therefore, judicious management of these inputs is necessary for the sustainability of these inputs.

• In our agriculture systems, spatial variability over the landscape is ignored and fertilizers, herbicide, pesticides, fungicides etc. are applied at uniform rate over the whole field.

• It has been recognized that crops and soils are not uniform within a given field. The management of in-field variability in soil fertility and crop conditions for improving crop production and minimizing the environmental impact is the crux of precision farming.

• Definitions • It is defined as the application of technologies and principles to manage spatial and temporal variability associated with all aspects of agricultural production (Pierce and Nowak, 1999).

• It is an integrated information and production-based farming system that is designed to increase long term, site specific and whole farm production efficiency, productivity and profitability while minimizing unintended impacts on environment.

Introduction

Energy is the major source required to maintain the structure and function of all living cells. This energy is derived from oxidation of carbohydrates, lipids and proteins that is taken in the form of diet. The energy liberated from the process of oxidation is generally captured in the form of ATP, which is known as energy currency of the living cells. Each gram of carbohydrate and protein gives about 4 Kcal on oxidation, while each gram of fat gives about 9 Kcal. Oxidation means addition of oxygen or removal of hydrogen from a compound or removal of electron from an ion or atom increasing its positive charge. Reduction means removal of oxygen or addition of hydrogen to a compound or addition of electron to an ion or atom decreasing its positive charge. Commonly the oxidation reactions are conjugated with reduction reactions and known as redox reactions. Redox reactions are often associated with release of energy. The redox chain constitutes chain of different compounds of increasing redox potentials between hydrogen and oxygen. The living cells depend on redox reactions for their energy requirements. The reactions start by removal of H2 from the substrate, which is then transferred to different components of redox chain, then finally to oxygen to form water. Components of redox chains have a redox potential higher than hydrogen and lower than oxygen.

Dairy: It is a room, building, or establishment where milk is kept and butter / cheese is made or it is the department of farming / farm that is concerned with the production of milk, butter, and cheese or an establishment for the sale / and distribution of milk and milk products.

Abstract

A field experiment was conducted at Central Arid Zone Research Institute, Jodhpur to assess the effect of weed management practices on production, resource use efficiency and monetary benefit in cumin. The experimental field was predominantly infested with weed species such as Chenopodium murale, C. album, Asphodelus tenuifolius and Heliotropium oralifolium.

Abstract

Three seepage tests were carried out for an earth canal at Rawakeeb Research Station (RRS)-west of Omdurman and an average seepage rate of 3.4 m/day was obtained. This value suggests that irrigation canal at RRS should be lined. In addition to that preliminary economic evaluation showed that canal lining is imperative in RRS. A concrete slab form was well designed for lining of RRS canal. Precasting technique and construction technique provided the required water tightness. Economic evaluation was done for RRS canal to investigate the extent of occurrence of supposed advantages, and to estimate costs and benefits and rate of return to lining. The capital expenditure (C), net present worth (NPW) and benefit/cost ratio were found to be 2600.4, 1961.9 and 1.3 respectively which offers a good indicator to adopt the technique.

Abstract

Women entrepreneurship means the process in which women initiate a business, gather all resources, undertake risks, face challenges, provides employment to others and manage the business independently. Where women population hovers around 50% of the total human population in the world so entrepreneurship by them plays a key role in the development of economy of both developed and developing nations. The problems faced by women entrepreneurs are heavy work load, irregular payment, lack of work guarantee and no maternity benefits, health problems, marketing, financial liberty and being away from home. A different culture is required to promote, motivate and develop sustainable infrastructure for fostering women entrepreneurship. Often, an entrepreneur has to go through a complex set of procedures and formalities to start a business, which not only create irritations and delays but frustrate her efforts until she is exhausted. An urgent need, therefore, is to simplify procedures and formalities. Part of the problem is one of attitudes, which are built on regulatory roles rather than developmental roles. All training and financial agencies need to be gender sensitive. The time has come for an effort to inculcate a spirit of enterprise, self-dependence, creativity, and high goals among women in developing nations. Hence, entrepreneurship must be made part and parcel of the education curriculum.

Agriculture Technology Management Agency (ATMA)

Extension Reforms were introduced during 2005-06 by the Department of Agriculture & Cooperation (DAC), Ministry of Agriculture, Government of India as a major intervention in addressing the constraints as observed in T & V and post T & V system by making the extension system farmer driven and farmer accountable through process and institutional reforms mechanism. The institutional mechanism in the form of Agricultural Technology Management Agency (ATMA) at district level was pilot tested under Innovations in Technology Dissemination (ITD) component of National Agricultural

Technology Project (NATP) in seven states viz. Andhra Pradesh, Bihar, Himachal Pradesh, Jharkhand, Maharashtra, Orissa and Punjab covering 4 districts in each State from 1998 to 2004. The key features of reforms are:

Food and nutrition are necessary for all living beings to maintain good health[1]. Thermal treatment is commonly used for preservation of food. Although application of thermal treatment can ensure food safety, it may cause undesirable changes in the nutritional, sensory and functional properties of food products[2]. Due to growing awareness of connection between the diet and the health, there is an increase in demands for fresh-like, palatable, additive-free and microbiologically safe food products with high nutritional value and quality[3].

About two-thirds of the developing world’s three billion rural people live in about 475 million small farm households, working on land plots smaller than two hectares. Many are poor and food insecure and have limited access to markets and services. Their choices are constrained, but they cultivate their land and produce food for a substantial proportion of the world’s population. Besides farming, they have multiple economic activities, often in the informal economy, to contribute towards their small incomes. These small farms depend predominantly on family labour. In China, nearly 98 percent of farmers cultivate farms smaller than 2 hectares – the country alone accounts for almost half the world’s small farms. In India about 80 to 85 percent of farmers are small. In Ethiopia and Egypt, farms smaller than 2 hectares constitute nearly 90 percent of the total number of farms. In Mexico, 50 percent of the farmers are small; in Brazil smallholders make up for 20 percent of the total number of farmers (Rapsomanikis, 2019).

Plant Pathogen

Pathogen is an inducer of disease.

A pathogen can therefore be defined as any factor that induces unresolved impairment or disruption of one or more important plant functions.

Some plant functions such as nutrient uptake, are highly localized. Others, such as respiration, occur in all living tissues. Still others, such as photosynthesis and photorespiration, are extensively coordinated. Pathogen effects therefore range from very local to very general.

Editing

Editing is the process of refining the content, structure, grammar, and presentation of a written work. Editing is done to make sure that your thoughts are communicated to the reader as clearly as possible.

It takes more than just changing a word, adding a comma here and there, and fixing spelling errors to edit a tale. The procedures below must be followed in order to edit effectively.

1. Read the story from beginning to end first. The writer’s intent will become clearer to you at this point. Then check to see if it addresses the following queries: what? Why? Where? When? Who? and how - regarding the topic.

2. Make your notes in the margin while keeping these inquiries in mind.

3. Next, consider the general level of education and comprehension of your magazine or letter’s readers. Make a note of every word you believe they won’t comprehend.

4. Next, determine how long the story should be. What room in your magazine can you offer it? It is preferable to rewrite the story rather than attempt to condense it by omitting some details if you need a very brief copy.

5. Verify that the information is logically ordered and, if a process story, that the directions are comprehensive and given in the right sequence.

Introduction
Social media has turned into an essential element of individuals’ lives students in today’s world of communication. Its use is growing significantly more than ever before especially in the post – pandemic era, marked by a great revolution happening to the recent investigations of using social media show that approximately 3 billion individuals worldwide are now communicating via social media (Iwamoto and Chun, 2020). This growing population of social media users is spending more and more time on social network groupings, as facts and figures show that individuals spend 2 hours a day, on average, on a variety of social media applications, exchanging pictures and messages, updating status, tweeting, favouring and commenting on many updated socially shared information (Abbott, 2017). In the digital age, social media have emerged as a powerful tool for disseminating agricultural technologies and knowledge. ICAR-Krishi Vigyan Kendra (KVK), Bengaluru Rural has effectively leveraged various platforms to bridge the gap between research and farmers, ensuring timely and relevant information reach the farming community. This article explores how KVK Bengaluru Rural strategically utilizes YouTube, Facebook, Instagram, and X (formerly Twitter) for technology dissemination.
I. Facebook
Facebook’s interactive nature allows KVK Bengaluru Rural to engage with farmers and build a strong online community. The fact that KVK’s Facebook channel has 5080 followers is a significant indicator of its reach and engagement within the farming community. The followers represent a substantial audience actively interested in the KVK’s activities and information, this indicates that, the KVK has successfully established a relevant online community. With this follower base, the KVK can effectively disseminate critical information, such as weather updates, market prices, and technological advancements, to a large segment of the local farming population. A significant follower count suggests that the KVK is perceived as a reliable and trustworthy source of agricultural information, farmers are more likely to follow and engage with organizations they trust.

Abstract

The protein classification prediction is an important Problem in molecular biology, and one that has attracted a lot of attention, because there is a gap between sequence and structure of proteins from various resources. The proteins can be usually classified into one of the four structural classes; they are all-a, all-b, a/b and a+b. To address the problem of protein classification, many different algorithms and efforts have been made so far. In this paper, a new rule based data mining method for the prediction of protein structural classes is constructed using Rough Sets algorithm. Rough Sets Theory (RST) is a new mathematical approach to study the realistic information (Z. Pawlak, 1982). It focuses on knowledge reasoning by the whole set directly approximating to the incomplete and uncertain information. There are studies on the knowledge reduction and features selection of mass data. To apply rough sets algorithm, a decision table is constructed using Amino acid compositions and eight physicochemical properties data as conditional attributes. The generated decision rules after reducing the decision system can be used to classify new objects.The classification results of Rough Sets is verified by using self-consistency and jackknife tests on the datasets constructed by G.P. Zhou and comparison is made with some of the previous works.

Introduction

Tree improvement through the application of genetic principles is directed towards modifying the heredity of tree populations so that they are able to meet the needs of the forester and the wood based industry. The breeder of annual crop plants resorts to hybridisation, selection, testing of the improved strains, multiplication of improved seeds and finally their release for commercial planting in that logical sequence. But the tree breeder, whose career may be shorter than the life cycle of the tree species taken up for improvement, tends to carry out the above operations in a modified form and often some of the operations are carried out concurrently.

Many of our tree species are wild unselected populations. They are, therefore, expected to exhibit considerable natural variability for many characters and also to respond well to selection for further improvement. Further, altitudinal and latitudinal variation in many characters between populations are expected for those tree species which have a wide geographical distribution. So, the selection of desirable seed sources or provenances is an essential step that is basic to all tree improvement programmes. The right provenance is identified through well laid out provenance trials at a number of locations in the area where the improved selection is to be grown. Further improvement is then planned and executed for exploiting the naturally available intrapopulation variation. The variation normally measured is the phenotypic variation which is the result of interaction of the genotype of the individual with the environment. However, what is essential for selection to be effective is genetic variation for the character under consideration. Genetic variation is assessed by appropriate progeny trials. Since many of the economically valuable characters of tree species are polygenically controlled and exbibit continuous variation, measurements have to be in metric units. The use of biometrical techniques for assessing and analysing this variation, therefore, becomes an essential requirement.

India is primarily an agriculture based economy, which implies, agriculture dominates the nation’s economic landscape. In the course of socioeconomic growth, agriculture is crucial. Around 58 per cent of the population in India relies only on agriculture for their livelihood. India is enriched with various agricultural and horticultural crops with diversified agro-climatic conditions and different soil types. India is one of the leading producing countries of cereals, pulses, oilseeds, fruits, vegetables etc. India is also have a prominent scope in allied sectors of agriculture includes livestock, poultry, forestry, sericulture etc. Among such crops, Moringa is the selected crop for this research study. Moringa (Moringa oleifera), which is popularly known as ‘Drumstick’ belongs to the family Moringaceae. Moringa is basically a native crop of India. This crop has its own therapeutic properties with greater nutritional content. Especially in South Indian cuisine, moringa pod is a highly regarded vegetable because of its distinctive flavour and fragrance.

Introduction

In a research laboratory, we frequently need weigh chemicals and prepare different solutions of varying strength, as per the requirements. Accuracy in weighing and preparation of solution, with respect to weight/volume and strength, determines the success of experiment. In turn, the accuracy depends on weighing of solid chemical and/or measuring the volume of liquid chemical/making up the volume. In this Chapter, weighing of chemicals using appropriate weighing balance, preparation of solutions of different strength, their dilution, and precautions while preparing will be discuss in brief.

Weighing of Chemical

The primary method to determine the amount of chemicals to be used is weighing the chemical by using a balance.

In general, there are two types of balances to weigh chemicals in a laboratory:

1. Standard laboratory balance

2. Analytical balance

Standard Laboratory Balance

Generally, a standard laboratory balance is used for weighing a chemical when an error of ±0.02 g is acceptable. It is also used for pre-weighing, where approximate mass needs to be determined. Precise mass of the chemical is then determined using an analytical balance. Following are the steps in using a weighing balance in a laboratory.

8.1 What is stress?

• Physics:Mechanical force per unit area applied to an object.

• Biology:Stress is any adverse environmental factor or condition that affects normal metabolic or physiological processes. It may be :

• Biotic stress (living) • Abiotic stress (non-living) 8.2 Abiotic stress

• Abiotic stress is defined as:“The negative impact of non-living factors on the living organisms in a specific environment”

• Only 10% of the world arable land may be categorized as free from stress.

8.2.1 Type of abiotic stress

8.2.1.1 Temperature stress

• Temperature is one of the most important components of climate. It plays vital role in the production of horticultural crops.

• The different activities of plant like growth and development, respiration, photosynthesis, transpiration, uptake of nutrients and water and reproduction (Such as pollen viability, blossom fertilization fruit set etc.), carbohydrate and growth regulators balance, rate of maturation and senescence, and quality, yield and shelf life of the edible products.

• The above function of the plant should be well when the temperature at the optimum range.During high temperature plant does not perform proper functions of growth, where in low temperature physiological activities of the plant are stopped.
