Key Points

• The most frequent physical damage in animals is an aural hematoma;

• Otitis externa is known to result in Zepp's operation, or drainboard from the lateral ear wall.

Introduction

An alternative name for the ear is the sensory organ of hearing. It could display both functional issues and structural abnormalities.

Anatomical abnormalities

Diseases of Pinna

The pinna is affected by several dermatological disorders. In rare cases, a disease only first affects the pinna or the pinna alone. A diagnosis is best determined based on the findings of a comprehensive history, a full physical and dermatologic examination, and the thoughtful selection and assessment of certain diagnostic tests, as with any dermatologic disorder.

Key Points

• Dystocia, uterine prolapse, obstetrics, and torsion of the uterus are among the common obstetrical issues in dairy animals.

• These reproductive abnormalities cause dairy farmers to suffer significant f inancial losses.

Introduction

Every instance of obstetrical complications needs to be handled right away. Along with taking the case history, a general clinical assessment and examination should be performed. Dystocia is one of the various obstetrical problems that is more common in cattle.

Key Points

• Electrolyte Imbalance: Regularly monitor and rectify imbalances in potassium, sodium, and other electrolytes dependent on the individual situation. Prompt management requires early detection of metabolic emergencies.

• Fluid Management: To restore intravascular volume and prevent dehydration in many metabolic emergencies, adequate fluid replacement is essential.

• Continuous monitoring of vital signs, laboratory values, and clinical status is essential for evaluating the efficacy of interventions and making necessary modifications.

Introduction

A class of disorders known as "metabolic emergencies" affect metabolism and physiology abnormally in both congenital and acquired forms. Among these ailments are endocrine disorders, thyrotoxicosis, inborn metabolic inefficiencies, and illnesses linked to electrolyte imbalances. Hypercalcemia, hyponatremia, hypoglycemia, hyperglycemia, and diabetic ketoacidosis, as well as hyperuricemia, hyperuremia, and hypercreatininemia due to renal failure, lactic acidosis, hyperammoniemia, and adrenal failure, are metabolic emergencies that pose a life-threatening risk.

Key Points

• Drug poisonings can be acute or chronic and result in the development of clinical signs and symptoms that may lead to animal disability or death, as well as extreme physiological and/or psychological changes.

• Drugs are substances that are used to prevent, treat, diagnose, and relive disease conditions by changing the physiology and/or psychology of the individual.

• Certain veterinary drugs have a specific antidote to counteract poisoning cases, while other veterinary drugs do not, and supportive therapy is required to counter these poisonings.

• Over-the-counter (OTC) medications, which are defined as human drugs or nutritional supplements that are available without a prescription, have potential risks for use in animals due to their increased toxicity.

Introduction

Many veterinary medications, which are used to treat both animals and birds, have the potential to poison the species to whom they are provided. These medications' toxic effects are mostly caused by giving them to the wrong species, at the wrong doses, or in the wrong combinations of medications. Certain medication poisonings can be identified due to patient individuality and eccentricities. As a result, there are many cases of these poisonings. This chapter discusses the poisoning caused by frequently and carelessly used veterinary medications, such as the toxicity of antibiotics and antibacterials, the toxicity of antiparasitic drugs, the toxicology of analgesics, the toxicity of cough treatments, the toxicity of the digestive system, the toxicity of vitamins, and the toxicity of topical preparations.

Key Points

• It might be necessary to administer oxygen or perform artificial respiration. Giving tranquilizers is not a good idea.

• Precaution: It's crucial to always follow the label's instructions on how to use pesticides since they provide information on how to do so. Warnings against using on unapproved species or in testing conditions must also be included on labels. A maximum of care should be made to prevent drift or drainage to neighboring fields, pastures, ponds, streams, or other properties outside the treatment area. In no case should amounts larger than those specifically recommended be utilized.

Introduction

It has been determined that a number of plant species are poisonous to animals. These plants not only posed a health risk to humans and animals, but they also significantly reduced cattle productivity. Many plants contain chemicals that can be dangerous or even lethal to animals. The degree of toxicity varies based on the animal species, the quantity of plant material ingested, and the particular poisonous compounds in question. In general, there are two categories of dangerous plants: those that are known to be toxic and contain toxic compounds, and those that are normally non-toxic but can turn hazardous in certain circumstances. Here are some typical plant toxicities, along with information on managing toxicity and clinical signs.

Packaging is an essential tool to make products stand out from the competition. Beyond the shelf appeal, packaging also provides protection to the contents from physical, chemical and microbiological hazards. However, a lesser known fact is that the same packaging material could also be a source of chemical contaminants, and hence, may impact food safety as well as food quality. Among the different components of packaging material, packaging inks play a critical role as they might hamper product and consumer safety.

Each packaging ink is a mixture of different chemicals and some of these chemicals might be harmful with the potential to migrate to the foodstuff. In terms of risk, the chemicals could be toxic, carcinogenic, mutagenic, repro-toxic and even endocrine disruptors. The chemical contaminants from the packaging inks can get transferred to the foodstuff by a process called migration.

Over the last two decades, a number of scientific papers have been published, revealing the migration potential of substances from the printed matter. However, the first big scandal that brought the subject alive was about the f indings of isopropyl thioxanthone (ITX, a low molecular photo initiator used in UV inks) in baby milk and other liquid foodstuffs all over Europe, resulting in a product recall in the year 2005. The food scandal alerted the packaging chain about the linkage between packaging inks and food safety. Consequently, the authorities issued strict regulations for the application of printing inks as well as general food control measures.

The village of Khan Saheber Abad is located in the Sagar subdivision of South 24 Parganas district in West Bengal, India. It is situated 4.8 km away from the sub-district headquarter Rudranagar (the tehsildar office) and 99.6 km away from the district headquarter Alipore. A training programme was conducted for the empowerment of rural tribal communities through sustainable inland fisheries development and utilisation of open water bodies in the village.

Challenges and opportunities

The Khan Saheber Abad is primarily a tribal dominated village. These Tribal people belong to the Santhal community. They have a low level of literacy, declining or stagnant population, and are economically weak, but they are very close to nature.

The demand for nutrients is rising, along with the population, which is rapidly expanding. The sustainability of life on earth now places a high focus on protecting the sources of sustenance. In this regard, aquaculture has a crucial role to play. The regulated raising of fish and other breeds in a particular environment is known as aquaculture. The natural resources and other elements required for sustainable development can be preserved using this method. The promotion of the value of nutrients and the expansion of employment prospects in the future are both made possible by aquaculture. Biofloc fish farming, which has set trends in fish farming all over India, facilitates recycling and reusing of the nutrients in the culture medium by filtering the unwanted substances and metabolites and converting them into nutrients, which benefits the zero exchange of water.

It is clear that Odisha has significant potential for aquaculture due to its vast brackish water resources. However, as the aquaculture industry grows, it is important for farmers to be knowledgeable about the inputs and techniques they use to ensure the sustainability of the industry. A total of 2.98 lakh ha of estuaries, 0.081 lakh ha of backwater, 0.80 lakh ha of Chilika Lake, and 0.32 lakh ha of cultivable brackish water area make up the 4.18 lakh ha potential brackish water area for fish and shrimp production. Additionally, proper disease diagnosis and management are crucial for reducing the risk of disease outbreaks and ensuring the health of the aquatic animals being farmed. With appropriate training and support from organisations such as the Aqua One Centre, farmers can improve their practices and increase their yields, while also contributing to the economic growth of the region.

What is dispersion?

In statistics, dispersion (also called variability, scatter, or spread) is the extent to which a distribution is stretched or squeezed. Common examples of measures of statistical dispersion are the variance, standard deviation, and interquartile range. For instance, when the variance of data in a set is large, the data is widely scattered. On the other hand, when the variance is small, the data in the set is clustered.

Dispersion is contrasted with location or central tendency, and together they are the most used properties of distributions.

Measure of dispersion

(a) Range

The range is defined as the difference between the largest and smallest observations. Range(X)= Max(X)- Min (X)

Example

The range in statistics for a given data set is the difference between the highest and lowest values. For example, if the given data set is {2,5,8,10,3}, then the range will be 10 – 2 = 8. Thus, the range could also be defined as the difference between the highest observation and lowest observation.

We can categorize statistical theory into two general parts.

1. Firstly, there is descriptive statistics which uses the appropriate tools, typically tables, diagrams and/or numerical measures, to describe a data set and provide a summary of its distribution.

2. In addition, there is inferential statistics which is concerned with drawing conclusions about a population using information obtained from a representative sample selected from it.

(a) One aspect of statistical inference is the estimation of a population parameter by the appropriate sample statistic (e.g. the population mean by the sample mean).

(b) The second aspect of inferential statistics is hypothesis testing. In this case, we examine a hypothesis, framed in terms of the parameters in one or more populations.

Estimation is concerned with description whereas hypothesis testing is ultimately concerned with decision.

Basic concepts of hypothesis testing

Hypothesis testing is a process that is concerned with making conclusions about the population using the information obtained from its sample.

• In statistics, best linear unbiased prediction (BLUP) is used in linear mixed models for the estimation of random effects. BLUP was derived by Charles Roy Henderson in 1950 but the term “best linear unbiased predictor” (or “prediction”) seems not to have been used until 1962 (Henderson, 1975, 1985).

• “Best linear unbiased predictions” (BLUPs) of random effects are similar to best linear unbiased estimates (BLUEs) of fixed effects. The distinction arises because it is conventional to talk not about estimating fixed effects but rather about predicting random effects, but the two terms are otherwise equivalent.

BLUE and BLUP are both acronyms used in statistics

• BLUE stands for Best Linear Unbiased Estimates and refers to the solutions (or estimates) associated with the fixed effects of a model.

• BLUP stands for Best Linear Unbiased Predictions and refers to the solutions (but identified as predictions) associated with the random effects of a model.

• Both BLUEs and BLUPs are linear functions of the data and have the lowest variance.

• The expected value of a mean estimate for an individual equals its true value for BLUEs.

• BLUPs are similar to BLUEs, but it is conventional to talk about estimating fixed effects but predicting random effects.

• BLUP is the standard selection method in animal breeding where the breeding values of sires are estimated based on progeny performance to select superior genotypes and to breed superior families.

Introduction

Modern-day agriculture and civilization together demand increased production of food to feed the global population. New technologies and solutions are being applied in the agricultural domain to provide an optimal alternative to gathering and processing information while enhancing net productivity. At the same time, the alarming climate change and increasing water crisis demand new and improved methodologies for modern-age agricultural and farming f ields. Automation and intelligent decision-making are also becoming more important to accomplish this mission in flower production. In this regard, the Internet of Things (IoT) ubiquitous computing, wireless ad-hoc and sensor networks, radio frequency identifier, cloud computing, remote sensing, etc. technologies are becoming increasingly popular.

Most of the IoT-based applications are targeted for various applications. For example, IoT for environmental condition monitoring with information on soil nutrients are applied to predict crop health and production quality over time. Irrigation scheduling is predicted with IoTs by monitoring the soil moisture and weather conditions. The world’s first IoT device was invented in the early 1980s at Carnegie Melon University.

Introduction

Cranberry (Vaccinium macrocarpon Aiton) belongs to the Ericaceae family and is native to North America. Cranberries are also known by various other names, including American cranberry, bearberry, and lingonberry. The plant has a diploid chromosome number of 24 and grows in acidic, nutrient-poor soils in wetlands and bogs. It is an important commercial crop worldwide due to its high nutritional value, antioxidant properties, and health benefits. Cranberries are primarily consumed as juice, dried fruit, or in the form of sauces and jellies. They are a rich source of vitamins C and E, dietary fiber, anthocyanins and essential minerals such as potassium, manganese, and copper. The fruit is also used in the pharmaceutical industries due to its anti inflammatory, antimicrobial, and anti aging properties (Santos et al., 2017; Wang et al., 2017).

The composition of cranberries is quite remarkable, with high levels of antioxidants, including phenolic compounds such as flavonols, anthocyanins, and proanthocyanidins. These compounds are responsible for the fruit’s vibrant red color and are thought to provide many of the health benefits associated with cranberries. Cranberries are an important crop in the United States, Canada, and Chile, with significant economic value. They are primarily consumed as juice or in processed forms, such as sauces and jams. Cranberries are also used in the production of dietary supplements and cosmetics.

Introduction

This led to an extended debate and international co-operation in the recognition of plant-related intellectual property rights, resulting in a greater attention being paid to questions of ownership of genetic resources. At the same time concerns for sustainable use of biological diversity were also raised.

One of the major events was the Convention on Biological Diversity (CBD) which came into force in 1993, which was adopted during the Rio Earth Summit of the United Nations. It was the first legally binding institutional mechanism, providing for conservation and sustainable use of all biological diversity and intends to establish the process of the equitable sharing of benefits arising out of the use of biodiversity.

The Convention on Biological Diversity

The CBD was conceived in the 1980s and was negotiated under the leadership of the United Nations Environment Programme (UNEP). It was adapted in June 1992 at Rio de Janeiro, at the Earth Summit, and is effective since December 1993.

Crop Production

Crop production refers to the cultivation and management of plants for the purpose of generating agricultural yields. It encompasses a wide range of activities, starting from land preparation and seed selection to harvesting and post-harvest handling. Crop production involves the application of scientific principles, traditional knowledge, and modern technologies to optimize plant growth, minimize losses, and maximize yields. The goal of crop production is not only to meet the demands for food, fibre, and fuel but also to do so in a sustainable manner that preserves the health of the soil, water resources, and surrounding ecosystems. It is a fundamental component of agriculture, playing a pivotal role in sustaining human life and supporting economic development around the globe.

Principles of Crop Production and Management

The principles of crop production encapsulate the fundamental guidelines and practices that govern the cultivation and management of crops. These principles serve as a framework for farmers to optimize agricultural productivity, sustainability, and profitability. Here are some key principles:

1. Soil Health: Healthy soil forms the foundation of successful crop production. Principles related to soil health emphasize the importance of maintaining soil fertility, structure, and biological activity. Practices such as soil testing, organic matter incorporation, and conservation tillage are employed to enhance soil health and productivity. Soil health is a foundational principle in the realm of crop production, influencing every aspect of plant growth and agricultural sustainability. Healthy soil serves as a reservoir of essential nutrients, a habitat for beneficial microorganisms, and a medium for root development. The principles of soil health emphasize the importance of maintaining soil fertility, structure, and biological activity through practices such as organic matter incorporation, conservation tillage, and cover cropping. By replenishing organic matter, optimizing soil structure, and fostering a diverse microbial community, farmers can enhance soil health and productivity. Soil testing is another key principle, enabling farmers to assess nutrient levels, pH balance, and other soil properties, guiding the application of fertilizers and soil amendments. Moreover, conservation practices such as crop rotation, agroforestry, and erosion control help protect soil from degradation, preserving its long-term productivity and resilience. Embracing these principles of soil health not only promotes higher crop yields but also mitigates environmental impacts, enhances water retention, and fosters ecosystem biodiversity, laying the groundwork for sustainable agriculture now and in the future.

Introduction

The objec tive of genomic research in any species is to sequence the whole genome and to decipher functions of all the different coding and non-coding seq,uences. The technology for large-scale DNA sequencing has enabled the scientists to undertake genome sequencing project in a realistic time scale. Since the time of first ‘large’ genome sequencing in bacteriophage λ in 1983, the projects on different groups have been completed. Eg. Escherichia coli, Saccharomyces cerevisiae, Arabidopsis thaliana, Oryza sativa, Caenorhabditis elegans, Drosophila melanogaster, Mus musculus, Pan troglodytes, Homo sapiens.

There are certain species which have been chosen for genome projects as model organisms. A model organism is a non-human species that is used to understand biological phenomena with a thought of gaining insight into the working of other organisms. They are chosen on the basis of their small genome in size, diploid genetics with a few chromosomes, rapid life cycle, easily transformed, well positioned in plant phylogeny, small stature for plant growth in a small space, large number of seeds produced, convenient for discovery of gene-trait discovery at low cost and speed and well investigated. They include,

• Monocots – Oryza sativa

• Dicots – Arabidopsis thaliana

• Temperate grasses – Brachypodium

Genomics-driven approaches to Genebank management

• Pre-breeding can facilitate the characterization and utilization of PGRs.

• Allele mining involves searching useful alleles of genes from a wide germplasm collection.

• Transformation of germplasm collections into bio-digital resource centres like

• DNA Barcoding,

• DNA fingerprinting.

Pre-breeding

• Pre-breeding is the step before practical breeding.

• Aim - To introduce new desirable traits/genes into an adapted genetic background. This will broaden the genetic base in a breeding material in pace with environmental changes.”

• The main link between the germplasm conservation and its use in plant breeding

• A vital contribution of pre-breeding is increasing the total genetic diversity in crops and finding specific genes and traits.

• Main link between conservation of PGR in gene bank collections and utilisation of these resources in agriculture and horticulture.

• Essential for linking genetic diversity arising from wild relatives and other unimproved materials for utilization.

• These activities are a collaboration between germplasm curator and the plant breeder who need to work germplasm collections and how new traits from these collections can bred into new varieties.

Previous year questions

1. Introduction?

2. Role of private? Introduction

• The Indian seed industry used to be dominated by public sector seed companies. However, following the easing of government regulations and the implementation of a new seed policy in 1988, the private sector seed companies have started playing a major role in seed development and marketing.

• More recently, the government’s decision to embrace biotechnology as a means of achieving food security has attracted several leading biotechnology-focused multinational seed companies to India.

• The composition of the seed industry, by volume of turnover, has reportedly reached a ratio of 60:40 between the private and public sectors.

Arrangement of plants and animals into groups according to their close resemblance, naming and describing them is called classification. Classifying the plants into groups is called systematic botany. The main aim of classification is to name the plant to describe them and to bring out their resemblances in order to throw light on their relationship and common ancestor. It is to indicate primitive and advanced plants systematically.

Need for Classification

It is not possible for anyone to study all the organisms. But if they are grouped in some convenient way the study would become easier as the characters of a particular group or a family would apply to all the individuals of that group. Classification allows us to understand diversity better.

Classification of plants

Entire plant kingdom is divided into four main groups.

1. Thallophyta 2. Bryophyta 3. Pteridophyta 4. Spermatophyta or Phenerogams

Primary Dicot Stem

A stem with only primary permanent tissues is called primary stem. It represents a young stem. The different tissues present in dicot stem are arranged in concentric layers. e.g. Sunflower

I) Epidermis

Epidermis is the outermost layer of the stem. It is made up of compactly arranged parenchymatous cell, which look rectangular in transverse section. The cells are transparent and devoid of chloroplasts. The outer walls are convex, thickened and cutinized. On the outer side they possess a layer of cuticle. The internal walls of the epidermal cells are thin. The radial walls are thick towards the outer side and gradually become thin towards the inner side. Pits occur in the radial walls. The epidermis of sunflower bears several unbranched multicellular hair. At place the epidermis contains minute pores called stomata or stoma. Each stomata or stoma has a pair of specialized kidney shaped cells called guard cells. The guard cells have a few chloroplasts. By their swelling, the two guard cells can form a pore between them.

Secondary Growth in Dicot Stem

The formation of secondary tissue from the lateral meristem is called secondary growth. It increase in diameter of the stem. A stem with secondary tissues is called secondary stem. Secondary tissues are formed by two types of lateral meristem, vascular cambium and cork cambium or phellogen. Vascular cambium produces secondary vascular tissues while phellogen form periderm. Secondary growth occurs in perennial dicots such as trees and shrubs. It is also found in the woody stems of herbs. In such cases, the secondary growth is equivalent to one annual ring, e.g. sunflower.

Formation of secondary vascular tissues

They are formed by the vascular cambium. Vascular cambium is produces by two types of meristems: intrafascicular and interfascicular cambium.

1. Intrafascicular cambium is a primary meristem which occurs as strips in vascular bundles.

2. Interfascicular cambium arises secondarily from the cells of medullary rays which occur at the level of intrafascicular strips.

3. These two types of meristematic tissues get connected to form a ring of vascular cambium

Physical properties of wood

The versatility of wood is demonstrated by a wide variety of products. This variety is a result of a spectrum of desirable physical characteristics or proper ties among the many species of wood. In many cases, more than one property of wood is important to the end product. For example, to select a wood species for a product, the value of appearance-type properties, such as texture, grain pattern and color, may be evaluated against the influence of characteristics such as machinability, dimensional stability and decay resistance.

28.1. Aim

Estimation of reducing sugars in fresh fruits and processed products using Lane and Eynon method.

28.2. Theory

Sugars are inherently present in different fruits and vegetables or added during preparation of different products. They are added to the fruit products to improve the taste and also to act as a preservative. Glucose and fructose in the fruits represent reducing sugars while sucrose or cane sugar added represents the non-reducing sugar. They are estimated by using Lane and Eynon method which measures sugar as reducing sugar and total sugar as invert sugar.

Introduction

Over 250 million people are directly affected by land degradation worldwide. Each year 12 million hectares are lost to deserts. Only 11 % of the global land surface can be considered as prime or Class-I land.

India contains 2.4 % of world’s total land. Out of the total geographical area of 329 million ha of the country, land use statistics are available for about 93 % of the total area which comes around 306 million ha. The arable land (net area sown plus the current and other fallow lands) was estimated at 166.14 million ha (54.2%) while the area under forest was accounted at 69.02 million ha (22.6%). Land put to non-agricultural uses was estimated at 22.97 million ha (7.5%) and the barren and uncultivable land at 19.44 million ha (6.4%). Permanent pastures and other grazing lands where estimated 11.04 million ha. (3.6%), land under miscellaneous uses at 3.62 million ha. (1.2%) and the cultivable waste land at 13.08 million ha (4.5%). By summing up these figures, the reporting area comes out 306 million ha.

Introduction

Pedology:- Pedology word drive from Greek word pedon, means soil or earth and logos means to study. Pedology is concerned with origin of the soil, its classification, distribution and character (Physical, Chemical and Biological).

Definition:- Soils are natural bodies made from both mineral and organic materials and capable of supporting plants out-of-doors.

Composition of soil on volume basis (Soil components)

i. Mineral matter :- 45%

ii. Organic matter :- 5%

iii. Soil water :- 25%

iv. Soil air :- 25%

Soil formation is a long term process. It takes several million years to form a thin layer of soil. The soil is made up of broken down rock material of varying degree of fineness and changed in varying degrees from the parent rocks by the action of different agencies such that the growth of vegetation is made possible. As soil is a complex mixture of various components, its formation is also more complex. The Formation of a particular type of soil depends upon the physico-chemical properties of the parent rock, intensity and duration of weathering, climatic and other parameters.

Introduction

Calcareous soils are those that contain high levels of calcium carbonate (CaCO3 ) that affects soil properties related to plant growth, such as soil water relations and the availability of plant nutrients (Elgabaly, 1973), and give effervescence visibly releasing CO2 gas when treated with dilute 0.1 N hydrochloric acid. The pH of calcareous soil is > 7.0 and also regarded as an alkaline (basic) soil.

Calcareous soils have often more than 15% CaCO3 in the soil that may occur in various forms (powdery, nodules, crusts etc.). Soils with high CaCO3 belong to the Calcisols and related calcic subgroups of other soils. They are relatively widespread in the drier areas of the earth. They occupy >30% of the earth’s surface, and their CaCO3 content varies from just detectable up to 95% (Marschner, 1995).

Formation of calcareous soils

Calcareous soils occur naturally in arid and semi-arid regions because of relatively little leaching. They also occur in humid and semi-humid zones if their parent material is rich in CaCO3 , such as limestone, shells or calcareous glacial tills, and the parent material is relatively young and has undergone little weathering. Some soils that develop from calcareous parent material can be calcareous throughout their profile. This will generally occur in the arid regions where precipitation is scarce. It has been estimated that these soils comprise over one-third of the world’s land surface area (Taalab et al. 2019, Aboukila et al. 2018).

Introduction

The term multipurpose trees (MPT) refers to all woody perennials that are grown to provide more than one significant function (shelter shade, land sustainability) of the land use system they implement. More emphasis is given to trees which are indigenous in nature and have the capability to fix atmospheric nitrogen. All trees are said to be multipurpose. The term “multipurpose” as applied to trees for agroforestry refers to their use for more than one service or production function in an agroforestry system (Burley and Wood, 1991).

Multipurpose trees species (MPT) are grown to provide more than one significant crop of function or form. These may include fuel wood, fiber, fodder, flower, fruit, fertilizer (6F) timber, industrial purpose, nitrogen f ixing, soil conservation, soil protection and rehabilitation, shade and nurse trees, medicine, windbreak, shelterbelts, live fences, aesthetic or recreational purpose, shown in Table 16.1.

The historical origins of diffusion research can be traced back over 200 years. In the early 18th century, French judge and sociologist Tarde wrote "The Laws of Imitation" (1903). He viewed the diffusion of innovation as arising from conscious and unconscious social imitations among individuals. Tarde introduced seminal diffusion concepts such as the S-curve, opinion leaders, and perceived compatibility.

Following Tarde, German political philosopher and sociologist Simmel published "Conflict and the Web of Group Affiliations" (1922). In this work, Simmel explored how the relationships in which individuals are embedded influence their responses to innovations. He also suggested that individuals outside a social system can introduce new ideas into that system.

In the 1920s, American cultural anthropologist Kroeber studied both the spread of innovations and how cultures recursively shape innovations. These early works contributed to the development of diffusion research in sociology during the 1920s and 1930s.

Aristotle (384 to 322 BC), an ancient Greek philosopher and scientist (Fig. 1.1) developed the concept of meteorology as a study of the lower atmosphere. Over the years meteorology developed as a science of atmosphere which deals with the physics, dynamics and chemistry of the atmosphere and their effect upon the earth’s surface, oceans and thereby life in general either directly or indirectly.

As the atmospheric conditions change from time to time in a given area and from place to place in a given time, climatology was developed as a science which studies the average conditions of the weather and its variability over a long period of time.

All most all the human activities are greatly influenced by the weather and climate to a greater extent. Therefore, the scope of meteorology encompasses various activities which are of considerable economic significance as detailed here below;

1.1 Housing

The design and construction of houses, buildings, industrial structures etc. depends upon the weather and climate of the region. Orientation of doors, windows roofs of the buildings are usually designed to provide maximum comfort and convenience to the people.

Clouds play very important role on weather and climate. The formation of clouds takes place when water condenses in the sky. Clouds are visible accumulation of tiny water droplets and ice crystals in the Earth’s atmosphere. The moisture is always present in the atmosphere though it may not be visible. Clouds form when air becomes cooler until the water vapour present in it condenses to liquid form. The condensation over oceans occurs around solid particles like salt, dust, smoke etc. suspended in the atmosphere. The type of clouds depends upon temperature and wind. The clouds are classified based on physical appearance and the height at which clouds are formed (Fig. 7.1).

A scientific evaluation of the physical characteristics of the land, the properties of the soil, and the management techniques is called land capacity categorization. Understanding potentiality, capacity, and appropriateness for the best possible use of land is the primary goal of land capability categorization. Measuring land capacity provides an objective assessment for land preservation in certain ecological scenarios.

On the one hand, land capacity aids in determining if a piece of land is efficient for a certain use, and on the other, it aids in preventing inappropriate use of the land, which poses a risk of erosion and degrades the quality of the land. Therefore, in order to maximise production, each piece of land’s potential should be assessed taking into account both its pedo-geomorphic characteristics and any constraints resulting from environmental threats. Additionally, under the necessary management practices, capacity categorization allows farmers to use the land appropriately for sustainable output.

French bean (Phaseolus vulgaris L.) is a nutritious protein-rich legume vegetable crop cultivated in all parts of the world except Antarctica. Immature pods are consumed as vegetables, and matured pods are used as grain legumes (Allem, 2013). French bean is cultivated in 1.65 million hectares of area with a production of 26.98 million tonnes and productivity of 16.36 tonnes per hectare for vegetable purposes. As a grain legume, French bean was cultivated in 33.02 million hectares with a production of 28.90 million tonnes and productivity of 874.1 kg/ha during 2019 globally. In India, French bean is grown in 2.56 lakh hectares for vegetable purposes and 126.91 lakh hectares for grain legume purposes with a production of 7.26 lakh tonnes as immature pods and 53.10 lakh tonnes of grain legumes with a productivity of 2.83 t/ha of green pods and 418.4 kg/ha as grain legumes (area, production and productivity of livestock, Food and Agriculture Organization of United Nations, 2020). However, the area, production and productivity statistics of beans in FAO statistics may also include other beans such as mung bean and others (Sharma et al., 2013). French bean is also known by other names such as common bean, kidney bean, dwarf bean, haricot bean, string bean and garden bean. In India, French bean is also known by different names as Frash bean and Rajmah in Hindi, Shravanghevada in Marathi, Thingalaware in Kannada and Fras bean in Punjab.

1. Introduction

The term "sustainable development" was originally used in a 1953 article by Joseph L. that was published in Land Economics. The notion was employed to depict the degree or pace at which an environmentally friendly resource is employed for a particular objective while guaranteeing its long term availability. Organizational dynamics, social interactions, and cultural norms all change with the times. These changes are making environmental problems worse and bringing up questions about pollution and the requirement for a safe natural environment. They are being caused by changing human behavior and population expansion (Kami?ska, 2021; Gaffar et al., 2021). Organizations have been forced to review their approaches to dealing with these urgent environmental issues as a result of the increased awareness. Academic libraries have been particularly well-positioned to implement eco friendly practices because they are service-oriented establishments to adopt eco-friendly practices in their operations (Pangail, 2017).

No doubt Village library is a part of public library. Village library plays an important role for creation knowledge in different field. As we know that maximum people in the village area not aware about their right, even they not know reading and writing. so the rate of literacy is poor. Therefore it can be mentioned that the illiteracy is the main barrier for their development and it will harm their day to day life. Many people in the villages is involve themselves in farming. Agriculture is the main of earning sources. Villagers do not have adequate knowledge in farming and fertilizer that they used for better result even they not know the bad affect of fertilizer that they used. Their life style is not hygienic because of illiteracy.

1. Introduction

Libraries and information services have traditionally been seen as quiet sanctuaries of knowledge and learning. However, in today’s rapidly evolving digital age, libraries must actively market their services to ensure they remain relevant and accessible to diverse user groups. Marketing these services involves not only promoting the library’s offerings but also effectively communicating its value to the community. Marketing in case of libraries is necessary to offer benefits to users’ want, reduce barriers to use and access, persuade and inform the users, and carefully plan to satisfy users’ needs effectively. “Marketing is so basic that it cannot be considered a separate function within the library. Marketing is a central dimension of the entire library. It is the entirety of the library’s operations and services seen from a point of view of its final result, that is, from the customer’s point of view” (Gupta and Savard, 2010). Marketing library and information service is an established sub-set of management practices which identifies customer wants and needs and meets those needs within the resources of the organization (Gupta, Koontz & Massisimo, 2013).

1. Introduction

Higher educational institutions especially the agricultural universities and institutes have multifaceted mandate which includes teaching, research and extension. Scientific information is generated at rapid pace in the form of research papers, project reports, conference/Seminar proceedings, Theses/ Dissertations, books and so on. It is necessary to manage, preserve and share the intellectual output to the academic community for innovations and betterment of the society. Technological developments, open access and open archive movements have facilitated easy access to information. Open access literature available in public domain removes access as well as price barriers. Realizing the importance of preserving valuable digital and print material of an institution idea of developing institutional repositories was invigorated. It is online digital content free of cost and mostly free from restrictions of copyright and licensing. In other words, it is royalty free literature which can be applied to any digital content that are born digital or the older works digitized later in life. Researchers are not well aware of the various channels to enhance the visibility of their work such as scholarly journals and conferences. Further they don’t identify existing library provisions that could help them to share their work on different platforms due to lack of awareness about it. So there is need to create awareness among masses about the institutional repositories and its role in disseminating scientific output of an institution. Institutional repositories are the need of hour for to showcase the research output of an institution.

Today, all the organisations rely on assessments of data provided by their users, consumers, internal procedures, and day to day operations to find new avenues for betterment and expansion of the product and services. These insights provide a large and intricate set of professionally generated, maintained, analyzed, and modified facts. "Big Data" refers to the vast amount of data (Bansal, 2022, April 6). For instance, social media platforms facilitate human contact every day and millions of people connect and share a vast array of diverse types of information through these platforms. Big Data is viewed as "incredibly significant" in academic research. In the Big Data context, data visualization tools and technologies are essential for analyzing large amounts of data and making decisions based on facts (Adilin Beatrice, 2021, March 2). Information and data are represented graphically in data visualization. By using visual components like charts, graphs, and maps, data visualization tools provide an intuitive way to observe and understand trends, outliers, and patterns in data. The process is called Big Data Analytics that describes the process of uncovering trends, patterns, and correlations in large amounts of raw data to help make data-informed decisions in various research works.

1. Introduction

The idea of Green Libraries transcends mere energy conservation or waste reduction. It encapsulates a broader commitment to sustainability, encompassing green building practices, sustainable operations, environmentally friendly collections, and programs that educate and engage communities on sustainability issues. This essay explores the multifaceted nature of Green Libraries, examining their significance, the principles that guide them, and their impact on communities and the environment.

2. The Emergence of Green Libraries

The Green Library movement is relatively recent, gaining momentum in the late 20th and early 21st centuries. This movement arose from a growing recognition of the library's role in society as a community hub and educational institution. Libraries, traditionally seen as repositories of knowledge and culture, began to evolve in response to societal shifts towards environmental consciousness.

1. Introduction

Organizing and disseminating the amount of information being generated in the age of information explosion is the challenge for library staff. According to Ranganathan’s fourth law of library science it is very important factor today, that how quickly library provides its information to the users. So, in this modern era to do this work beautifully, it needs the help of advance technology. Not only that, but also requires staff training.Even the library continuously changes its concepts to keeping the modernity, like library known as ‘Knowledge Resource Centre’, the books and non-book materials known as information and so on.Now a day the library has made its services better and better by using several technologies. From this point of view, the use of RFID technology is very important. RFID consists of four components vis Tags, Antenna, RFID Reader and Software. Though its use, we make the work of circulation easier, we can identify any missing documents very easily. After all, we can say that no document can be taken out of the library without a proper way. So there is acceptance of stock verification work.

Homeopathic Prescription

A basis for homeopathic prescription involves identifying all the aspects of the case (detailed questioning to get the history in respect to animal, its behavior, its nutrition and management, vaccination and deworming status, past and present illness etc.), objective investigations (instrumental and laboratory), coupled with an overview of the picture and dynamics of the patient (it is more philosophical and subjective).

In recording symptoms (both present and past), special attention is to be paid to peculiar symptoms, mental state and generalities. Then appropriate remedy is selected through a process called “reportization”. After selecting an appropriate remedy, its correct potency is determined. Selection of the potency depends on the strength of vital force of the ailing individual, degree and extent of physical pathology and disease chronicity (Hahnemann,1994). Higher potency is selected if vital force is strong. For example higher potency are more suitable for young and growing animals. If tissue pathology is more, lower potency drug is advisable. The effect of higher potency drugs is for greater period of time. Effect of 1M potency may last for a month while that of 30C potency may last for a week. If pathology is not severe, 200C potency may be selected. In case pathology is significant, potency below 200C may be chosen. For weak and emaciated animals, potency 30C or below is advisable. Clear cut cases with strong mental symptoms are right candidates for high potency. Unclear case should be given low potency drug (Pitcairn, 1992). As soon as relief is observed, the drug administration should be stopped. Overmedication is the great error in homeopathic prescribing. In homeopathic prescribing, number of pillules taken in a single dose is less important. What matters is its potency and frequency.

Constitution

The word ‘constitution’ is derived from a Latin word “Constituere” that means to set up or to make up or to establish. Therefore, it is the structure, composition, physical make up or nature of something consisting inherited qualities modified by environment. Constitution in homeopathy is defined as the physical and mental makeup which is expressed through physical built, characteristics, desires, aversions, reaction including emotional and intellectual attributes. In other words constitution incorporates the individual’s combined physical body type (including nervous system and metabolism), mental thinking, style, emotional reactivity and temperament.

Classification of constitution

Human constitution has been classified in different ways in different systems of health care.

Mastitis

Mastitis is an economically important disease of dairy animals (cows and buffaloes) caused by a wide variety of pathogens (bacteria, some viruses, fungi).Major pathogens are Streptococcus agalactiae, Staphylococcus aureus, E. coli, Streptococcus uberis, Str. Dysagalactiae, Campylobactor, Corynebacterium pyogenes, Klebsiella spp. Pasteurella, Pseudomonas, Mycoplasma, Enterobactor, Trichosporon spp., Aspergillus fumigatus, Candida spp., Leptospira spp. and many more. Mastitis is also seen in lactating goats and sheep. As compared to ruminants mastitis is less common in bitches. Mastitis is an inflammatory disease of the udder parenchyma irrespective of its etiology. The disease occurs in clinical and subclinical forms. Clinical mastitis is of two types viz. acute mastitis and chronic mastitis. Subclinical mastitis is characterized by an increased number of somatic cells (>100,000 cells/ml) and/or pathogens in the milk with no apparent clinical change in the udder and milk. While clinical mastitis is associated with local (hot, pain full swelling of the udder) and general symptoms along with change in milk (increased cell count, increased pathogens, physical and chemical changes in the milk).

Definition

• Aetiology is defined as study of causation of disease.

Classification of Causes

• There are several agents or factors that can produce diseases in animals and can originate from within the body (intrinsic) or outside the body. (extrinsic).

Causes are classified into two categories

1. Predisposing causes (Intrinsic/Endogenous factors)

2. Definitive causes (Extrinsic/Exogenous factors)

Predisposing Causes

• Make the animal susceptible to definitive causes.

Nearly 19.9% of India's GDP (Statistics Times.com, 2021) and 54.6% (According to the 2011 census of India) of the people are employed in agriculture, which is important for the country's economy. Despite making up the majority of landowners, small and marginal farmers confront a number of obstacles including restricted access to government services, contemporary technologies, and financial choices. In addition, they frequently experience crop failures and are heavily dependent on shady middlemen and local loan sharks. Following the Y.K. Alagh Committee's recommendations, the Indian government introduced the idea of Farmer Producer Organisation (FPO) in 2001. These organisations are designed to empower small-scale farmers by giving them the ability to communicate directly with consumers and strengthen their negotiating position.

Small-scale farmer groups known as FPOs band together to promote their shared products and pool resources. In India, there are already over 7,300 FPOs registered, with over 1.5 million farmers joining. The Indian government wants to bring together over a million farmers under the FPO umbrella by setting an ambitious objective of 10,000 new FPOs being established by 2024–25.
