Water vapour transmission rate of packaging material

Introduction

Moisture Vapor Transmission Rate (MVTR), also known as Water Vapor Transmission Rate (WVTR), measures the rate at which water vapor passes through a material. MVTR is crucial in various industries where moisture control is vital. For example, moisture-sensitive foods and pharmaceuticals are packaged using materials with controlled MVTR to ensure quality, safety, and shelf life. In the textile industry, MVTR serves as a measure of breathability, enhancing comfort for outdoor clothing. In the building materials industry, managing moisture barrier properties in architectural components helps maintain appropriate moisture levels in the internal spaces of buildings. Various techniques are used to measure MVTR, ranging from gravimetric methods that assess moisture gain or loss by mass to advanced instrumental techniques capable of measuring extremely low transmission rates. It's important to note that special care must be taken when measuring porous substances like fabrics, as some techniques may not be suitable.

Soil texture is the relative proportion of sand, silt and clay in soil by weight. As per the classification of the inorganic soil particle by the International Society of Soil Science, diameters of the sand, silt and clay particles vary from 2 to 0.02 mm, 0.02 to 0.002 mm and less than 0.002 mm, respectively. There are 3 broad textural groups i.e sand, loam and clay and each broad textural group is subdivided into different textural classes depending upon the proportion of sand, silt and clay.

Introduction

Corona viruses are a huge family of viruses that cause many chronic diseases. A novel corona virus is an advanced strain of virus that has not been formerly identified in humans. Accepted recommendations to avert the spread of disease include regular hand washing, covering of mouth and nose when coughing and sneezing, avoid close contact (social distancing) with anyone showing symptoms,etc. Since majority of the people, especially children are sitting inside their home the usage of digital platforms are also increased dramatically.

COVID-19 and the associated lockdown in the country, has made a significant impact on the life of the population, across boundaries. Roughly saying, it has been near to a year since the foremost case of corona virus was reported in India, which was reported on January 30th 2020. Today that is, on 10th December 2020, 69,383,534 corona cases were reported, 1,578,707 deaths and 48,155,526 cases were recovered globally. In India 9,768,643 corona cases were reported, Of which 141,817 deaths and 9,253,388 cases were recovered. Whereas in Kerala, 2562 deaths, 658633 confirmed cases and 596593 recovered cases were reported. The only fluctuations are in the statistics, but the conditions are the same in each day. Of this study, we aim to create awareness on COVID-19 through interactive and pleasure seeking games. This helps to make them aware about the severity of the pandemic and also improves their psychological health. Lack of awareness and the passive attitude of people is the major factor of this situation. Children and the older adults are the major two communities more convenient to disseminate the information and at the same time they are the most vulnerable groups to the corona virus. Children are more enthusiastic and older people are more precaution. By providing the same games for both age groups, the interaction between both becomes closer and thereby improves the mental well-being of both in a family. So that the games were most effective in all respects. Games are activities usually undertaken for fun and enjoyment, but it not only meant for fun but also gives edutainment. Games are an effective tool to disseminate information by entertaining way.

1. Introduction

With the advent of globalization and subsequent economic liberalization, the focus of Indian agriculture is shifting from “subsistence” to “commercial” mode, where farming is viewed as a “business” rather than “life-support” system of poor farmers. Enabling farmers “decision-making” capacity is a primary driver of success in the market-oriented agriculture. This “commercial focus” has brought tremendous changes in the “nature” and “mode” of extension work. On the other hand, extension work organizations in developing countries like India, are being impacted by sharp decline in public sector funding, rapid technological innovations especially in the Information and Communication Technologies (ICTs), and the shift to a knowledge-based workforce. These developments created new opportunities for the extension workers to perform the information dissemination, capacity building and technology application more effectively. 

Introduction

In view of the present Indian agriculture scenario, farmer producers organisations (FPOs) are emerged as a most appropriate institutional form to mobilize small and marginal farmers ,improved their access to technology, inputs and markets. As per the report of National Council on Farmers, these organisations are mainly promoted to combine the advantages of decentralized production and centralized services, post harvest management, value addition and marketing. (NCF,2004). In order to meet the dream of Atmanirbhar Bharat and to make farmers atmanirbhar, Farmer Producers’ Organizations (FPOs) is an appropriate form to mobilize them. Recently Government of India has announced a budgetary provision of 4496.00 crore for five years for promotion of 10,000 FPOs.(Cabinet Committee on Economic Affairs,CCEA2020)

Also to improve agricultural productivity and income of the farmers, it is necessary to develop an entrepreneurial culture among the member farmers of an organisation. To make this organisational approach more successful, member farmers need to develop planning ability, decision making abilitiy, managerial qualities ,scientific attitude, organisational skills, participatory skills etc. The member farmers as an agripreneur should possess knowledge about improved production techniques, markets, consumer preferences , schemes, credit availability, policy advocacy to enterprise effectively under FPO.

Introduction

Entrepreneurship is regarded as one of the most important factors that contribute to economic development of a country. The current epoch of development is marked by structural changes in developing economies to create new opportunities of entrepreneurship. This is largely made possible by liberal policy interventions that foster enhancement of enterprises of all hues. Unlike previously, in every country, an entrepreneur is looked upon as an invaluable contributor to economic growth and development. This is more important in developing economies, as ‘entrepreneurship development’ has multiplier effects as it invariably fulfils other important pre requisites of development, viz. innovation, technological development, new institutions and human resource development. To put it in other words, without enterprise and entrepreneurs, there would be little innovation, little productivity growth, and few new jobs. This is more relevant in the agricultural sector since the emphasis has now shifted from mere enhancement of productivity to value chain management, through a process of extensive entrepreneurship development. More so, this has been identified as a strategy for sustaining the livelihood options of small farmers who have found it difficult to thrive the perils of price fluctuations, increasing cost of production and several other uncertainties that have plagued the farm sector.

Scientific leadership is a cornerstone of progress in agricultural sciences, playing a pivotal role in driving innovation, fostering collaboration, and addressing global challenges such as food security, climate change, and sustainable resource management. Effective scientific leadership ensures that research efforts are strategically aligned with pressing societal needs and that knowledge generated in laboratories and fields translates into tangible benefits for farmers, policymakers, and communities. This chapter delves into the qualities of effective leaders in agricultural sciences, the challenges they face, and strategies to nurture and support scientific leadership in this critical domain. The G20 Chief Science Advisers Roundtable (G20-CSAR), initiated under India’s G20 Presidency, is a flagship program aimed at fostering collaboration and enhancing access to scholarly scientific knowledge. This effort emphasizes the synergy of scientific expertise, ensuring that innovations and advancements are not only accessible but also utilized effectively to address pressing global concerns, such as climate change, public health, sustainable development, and digital transformation. Through this platform, India seeks to promote open science, equitable knowledge-sharing, and stronger international cooperation in research and development.
7.1. Qualities of Effective Leaders in Agricultural Sciences
To excel in agricultural sciences, leaders must embody a diverse range of qualities that enable them to inspire teams, foster innovation, and drive impactful research. These qualities include:
7.1.1. Strong Communication Skills
Effective leaders in agricultural sciences must be adept at communicating complex scientific concepts to diverse audiences. Whether engaging with fellow researchers, policymakers, farmers, or the general public, they must tailor their messages to ensure clarity and relevance. Strong communication skills are also essential for securing research funding, building partnerships, and advocating for science-based policies.

ABSTRACT

Over the last three decades, SAC has been engaged in the development and dissemination of remote sensing and GIS technologies for national development. These developments have originated from various initiatives related to national projects, sensor related research and in-house research and development on applications. A large multidisciplinary team of scientists develop technologies in various fields of applications like agriculture, coastal zone management, urban planning, forest and environment, etc. In addition, significant efforts are directed towards technology development for generic applications like photogrammetry and applications involving synergistic usage of remote sensing, GIS, GPS and satellite communication. Some specific examples of recent technological developments pertain to simulation modeling of crop yields, horticultural crop management, site selections for aquaculture, location of cold storage plants, large area crop production forecasting, base map creation, telegeoprocessing, mobile satellite services for fleet management, automated procedures for linear infrastructure planning, urban land use allocation planning.

An overview of these technologies and the modalities for their effective utilization by government, industries and users are summarized. Dissemination of these technologies for public bodies and private sector has been taken in the form of promotion of consultancy services in different application areas. Some major areas where these sectors have benefited through consultancies are estimation of cash and other field crops, city development planning, site selection for industry, land use change detection studies for environmental impact assessment, coastal regulation zone compliances and land use scenario, forestry related applications like catchment area treatment, forest fires monitoring, etc. Examples of consultancy services for private sector are included.

9.1 General Description

Education can help farmers in impoverished nations move away from environmentally damaging slash-and-burn agriculture (Nganje et al. 2001). The goal of their study was to see how much extension education can help people embrace agricultural strategies other than slash and burn. In Cameroon, farmers' cropping patterns are modelled as a function of farm size, farmer educational level, and extension professional visits, whether slash and burn, varied crops, or monocropping. According to the data, higher extension visiting rates reduce not just the risk of farmers choosing slash and burn agriculture, but also encourage them to switch to monocropping. Because monocropping is a trend toward export-oriented agriculture in Cameroon, it may help to promote greater economic development in Western Africa (Nganje et al. 2001). Continued extension education activities are therefore vital in decreasing the environmental damage caused by slash and burn agriculture while also encouraging the adoption of more profitable cropping strategies.

The negative impacts of shifting cultivation on the environment as farmers strive to provide for higher populations and the associated decline of shifting cultivation into an unproductive system have led most governments in Southeast Asia to perceive it as a backward method of cultivation (Thanh and Vien 2017). Consequently, governments throughout the region have tried to ban shifting cultivation. In Malaysia, for example, huge development programmes have been implemented to improve shifting cultivators livelihoods when they abandon shifting cultivation (Majid, 1983). The government of Laos has enacted land-use and forestry policies aiming at expanding forest cover, eliminating shifting farming, and supporting intensive commercial agriculture (Castella et al., 2013). For many years, the Vietnamese government has implemented strict rules and procedures to combat shifting cultivation. These include a large-scale programme called 'Fixed Cultivation, Fixed Residence' (officially known as Resolution No. 38/CP), which aims to permanently settle 'shifting fields' and 'shifting people' (McElwee, 2004), as well as a forestlandallocation policy that ties people to specific plots of land, effectively making shifting cultivation impossible (Castella et al., 2005).

Insects generally reproduce by laying eggs or ‘ova’. The initiation of growth inside an egg, which in most cases is preceded by fertilization, leads to a long series of changes, finally attaining the adult stage and in due course to sexual maturity and finally to reproduction of a new generation. This chain of events from the egg stage to adult constitutes the ‘life history’ or ‘life cycle’ of an insect.

Insects generally reproduce by laying eggs or ‘ova’. The initiation of growth inside an egg, which in most cases is preceded by fertilization, leads to a long series of changes, finally attaining the adult stage and in due course to sexual maturity and finally to reproduction of a new generation. This chain of events from the egg stage to death constitutes the ‘life history’ or ‘life cycle’ of an insect.

Eggs are laid singly or in batches of only a few or up to hundreds or  even thousands. Generally eggs are laid under conditions, where food is available for the feeding of the future young ones.  The eggs are generally smooth, elliptical or oval, but some have diverse shapes such as, disc-like, hemispherical, conical, globular, spindle and many other forms. The egg surface may also have a variety of textures. In some aquatic insects, the eggs are covered with a gelatinous secretion, which swells in water forming a jelly-like spawn. In mosquitoes, the lateral sides of the eggs are expanded, which serve as floats. Eggs vary in size, from microscopic to about 3.0 mm. in diameter and 5.0 - 6.0 mm. or even more in length.

The development of an insect is a continuous process, but on the basis of external manifestations, it is divided into definite stages. The stage within the egg is termed ‘embryonic development’, that after hatching ‘post-embryonic development’ and the changes of form during the post-embryonic development constitute ‘metamorphosis’.

Developing a nutraceutical or functional food is becoming mandatory as looking at the current nutritional status of the population over the world. Nutraceutical foods are proven to cause several health benefits to people. Hence the basic aim behind developing the nutraceutical chocolate bar was to fulfill the nutritional demands and provide some additional benefits to people. The product mainly contains two key ingredients that are, Drumstick (Morings oleifera) which has the most qualities to call a Superfood” and Quinoa (Chenopodium quinoa) which is referred to as “Mother of all grains”.

1. VARIETY

Variety is a seed/crop which suit the prevailing agroclimatic conditions, high yielding and possessing desirable attributes such as disease resistance, earliness and grain quality. Similarly, the seed should be pure, appropriate classes, and obtained from an authorised official agency.

Introduction Sea food processing is one of the major contributors in food processing sector. The purpose of seafood processing is to prevent the wastage and prolong the shelf life of highly perishable commodity. It also increases the economy of the country through exports (Gopal et al., 2014). India produce 9.6 million MT of sea food during the every year and is one of the largest fish producers in the world. 23% of marine products are processed currently in India (Sathianandan, 2017). Pasteurized crab meat is one type of processed marine commodity exported from India. Globally, the pasteurized blue crab and swimming crabs are the major contributors to the economic wellbeing of the seafood industry. In India, pasteurized crab meat industries are significantly contributing to the export markets. Among the crab export, 70-80% is exported as pasteurized crab meat (Jebadurai17, 2014).

32.1 Introduction

Development or embryogenesis refers to the events that occur after fertilisation. Embryogenesis in fish includes the formation of stages up to fingerlings. The process is similar in all fishes, but there are some differences between teleosts and elasmobranchs. The development of telolecithal eggs in fish begins soon after sperm fertilisation.

ABSTRACT

Mandarin Orange (Citrus reticulata Blanco.), known as ‘Suntala’ to the local populace, is a major cash crop and was once a pride of Darjeeling hills. It is grown in approximately 930 ha with an annual production of 148.224 metric tones and annual turnover of Rs. 25 crores approximately. Since early 1970s, orange orchards in the Darjeeling hills started to be unproductive inflicting huge economic loss showing severe citrus decline. Gradually the malady assumed alarming proportions and threatening the cultivation of the crop. The major causes for the bottleneck of the citrus industry in Darjeeling hills  is  the heavy incidence of insect pests, diseases and nutritional deficiencies.

Post-traumatic bleeding, caused by accidents or battlefield injuries, is a major worldwide issue due to the associated high fatality rate. Significant efforts have been made to develop hemostatic medications that help reduce post-traumatic bleeding. The use of naturally abundant and highly biocompatible polymers, such as alginate, can have a substantial impact on the efficacy, safety and cost effectiveness of hemostatic medicines.We haveexaminedthe effectiveness of developed hemostatic hydrogel (SA-CZ) containing calcium (Ca2+) and zinc (Zn2+) in treating low-pressure bleeding wounds with the added benefit of promoting faster wound healing. The hydrogel nature of the hemostatic formulation poses limitation as hemostatic material due to its fluid absorption capability. Therefore, we converted the formulation in the form of dry formulation. Further, we explored the use of dry hemostatic particles (SA-CZ DHP) made from sodium alginate supplemented with Ca2+ and Zn2+ to manage excessive blood loss after post-traumatic hemorrhage.SA-CZ DHP showed substantial in-vitro efficacy, as observed by the significant reduction in coagulation time with better blood coagulation index (BCI) and no evident hemolysis in human blood. SA CZ also showed enhanced cellular migration (1.58-fold) in-vitroand improved wound closure (≈70%) as compared with betadine (≈38%) at the 7th-day post-wound creation in-vivo (p<0.005).The safe SA-CZ DHP showed high absorption and accelerated blood clotting kineticswith reduced coagulation time (≈70%, p<0.0001) in whole human blood. SA-CZ DHP significantlyreduced the mean blood loss (≈90% in SD rats tail incision), and bleeding time (≈60%in BALB/c mice tail incision) was at par with commercially available Celox™hemostatic granules.

Introduction

The globally growing demand for water has ushered the need for its efficient and judicial utilizations in all fields, and agriculture in particular being a single largest consumer of water. The majority of irrigation projects in India perform at a very low efficiency, which calls for application of efficient water management technologies for meeting the increasing water demands. Estimation of soil moisture or crop evapotranspiration from climatic parameters provides objective criteria for irrigation management. Methods to estimate evapotranspiration require huge climatic data, which are seldom available and not applied by common crop growers. Determining crop water requirement through soil moisture measurement at several locations is time consuming, destructive exercise, and may not give proper assessment of crop water need. The plant based indicator approach considers the plant water status for scheduling irrigation. This might be considered as the ideal criterion because the plant water is a good integrator of the soil, water and climatic parameters.

Introduction

Crops diseases are caused by bacteria, virus, fungi and phytoplasmas. The detection of pathogenic bacteria and viruses in plants, planting material, vectors or natural reservoirs is essential to ensure safe and sustainable agriculture. The molecular based techniques, have evolved significantly during recent past that  allows the rapid and reliable detection of pathogens. The detection and diagnosis of plant pathogens is essential to take control measures and subsequently for eradication of the disease that causes.  Molecular detection is largely based on PCR or RT-PCR amplification following purification of nucleic acids from the samples, with the extraction of the target DNA.

Introduction
Introduction: The digestive system, or gastrointestinal (GI) tract, plays a fundamental role in the overall health and well-being of animals. In veterinary anatomy, understanding the structure and function of the digestive system is essential for diagnosing and treating various disorders that affect food intake, digestion, and nutrient absorption. This complex system is responsible for the mechanical and chemical breakdown of food, the absorption of nutrients, and the elimination of waste, making it crucial for maintaining homeostasis in animal species. Structural Organization: The digestive system can be divided into two main categories: the gastrointestinal tract and the accessory digestive organs. The gastrointestinal tract is a continuous tube extending from the mouth to the anus and includes the oral cavity, esophagus, stomach, small intestine, large intestine, rectum, and anus. Each segment of the GI tract is specialized for specific functions, reflecting the dietary habits and evolutionary adaptations of different species. Mouth and Esophagus: The digestive process begins in the mouth, where food is mechanically broken down by teeth and mixed with saliva, which contains enzymes like amylase that initiate carbohydrate digestion. The esophagus serves as a conduit for food, transporting it to the stomach through peristaltic movements. Stomach: The stomach is a muscular organ that serves as a site for food storage and initial digestion. It secretes gastric juices, including hydrochloric acid and pepsin, to denature proteins and activate digestive enzymes. The morphology of the stomach can vary significantly across species. In ruminants—such as cattle, sheep, and goats—the stomach is uniquely adapted for processing fibrous plant material through a complex structure consisting of four compartments: the rumen, reticulum, omasum, and abomasum.
1. Rumen: The largest compartment, the rumen, acts as a fermentation chamber where microbial digestion occurs. It is lined with a stratified squamous epithelium and contains millions of microorganisms, including bacteria, protozoa, and fungi, that help break down cellulose and other complex carbohydrates. The rumen’s large surface area, facilitated by papillae, enhances absorption of volatile fatty acids (VFAs) produced during fermentation, which serve as a primary energy source for ruminants.

Most often, a plant gets diseased when it is harmed by an abiotic agents or attacked by a pathogen. As a result, in the first scenario, interaction and contact between the pathogen and the plant are required for the occurrence of a plant disease. No disease develops even though a pathogen and a plant come into contact if the weather is too extreme at the time of the pathogen’s contact with the plant and for a while afterwards. This could be because the plant is able to fend off the pathogen’s attack or because the pathogen is unable to attack at all. Therefore, it would appear that in order for disease to manifest, a third component—a set of environmental factors falling within a favorable range—must also exist. The degree of disease severity in both individual plants and plant populations is impacted by changes in any one of the three components, which can each show significant fluctuation. Plants can exhibit genetic uniformity over a wide area, be of a species or variety that may be more or less resistant to the pathogen, or they may be too young or too old for the pathogen to prefer. All of these factors can either accelerate or slow down the rate at which a particular pathogen causes disease. The way the three elements of disease interact has frequently been represented as a triangle (Fig. 2-1), which is commonly known as the “disease triangle.”

Introduction
The development of disease in plants is a complex process influenced by the interplay between the host plant, the pathogen, and the environment. Understanding the stages and mechanisms involved in disease development is crucial for effective disease management strategies. This chapter will explore the disease triangle, the disease cycle, and the role of environmental factors in disease epidemiology.
The Disease Triangle
The disease triangle is a fundamental concept in plant pathology that illustrates the three essential components for disease development: the host, the pathogen, and the environment. All three elements must be present for a disease to occur.
a) Host: The host is the plant species that can support the growth and reproduction of the pathogen. Different plants exhibit varying levels of susceptibility to diseases, influenced by factors such as genetic resistance, nutritional status, and overall health.

Introduction
The endocrine system consists of glands and cells that secrete hormones directly into surrounding tissues or into the bloodstream to regulate various physiological processes. These hormones help maintain homeostasis, working closely with the nervous system, especially through the hypothalamo-hypophyseal connection, where the endocrine and nervous systems integrate their functions.
Pituitary Gland (Hypophysis)
The pituitary gland, often considered the “master gland,” is formed from oral and neural ectoderm. It is divided into two main parts: the anterior pituitary (adenohypophysis) and the posterior pituitary (neurohypophysis). Adenohypophysis: This portion develops from the roof of the stomodeum (primitive mouth) and consists of three parts: the pars distalis, pars intermedia, and pars tuberalis. It contains several cell types, including acidophils, basophils, and chromophobes, which secrete various hormones. For instance, acidophils release growth hormone (GH) and prolactin, while basophils produce hormones like adrenocorticotropic hormone (ACTH), thyroid-stimulating hormone (TSH), and gonadotropins (LH and FSH). The secretion of these hormones is regulated by the hypothalamus through releasing and inhibitory factors delivered via the hypophyseal portal system. Neurohypophysis: Originating from the floor of the diencephalon, the neurohypophysis consists of the median eminence, infundibular stalk, and neural lobe. It stores and releases antidiuretic hormone (ADH) and oxytocin, both synthesized in the hypothalamus and transported to the posterior pituitary. ADH regulates water balance, while oxytocin controls uterine contractions and milk ejection during lactation.
Hypothalamo-Hypophyseal System
The hypothalamus and pituitary gland form a unified control system. The hypothalamoadenohypophyseal system is responsible for regulating the anterior pituitary’s hormonal

Introduction

Meaning of Entrepreneur

The term “entrepreneur” is derived from the French verb entreprendre, which means “to undertake.” Historically, its meaning has evolved. In the early 16th century, it referred to individuals involved in engineering tasks like construction. By the 18th century, the term came to describe those engaged in economic activities. Over time, the concept of an entrepreneur shifted from someone participating in military ventures to someone actively involved in business and economic pursuits. Today, an entrepreneur is defined as an individual who innovates, organizes resources, and takes on risks to create new ventures or products with the goal of generating profits.

Richard Cantillon was the first who proposed the term “entrepreneur is an agent who buys factors of production at certain prices in order to combine them into a product with a view to selling it at uncertain prices in future.”

Introduction
Development of eye
The eyeball is a complex structure having tunics i.e. fibrous tunic (sclera, cornea), vascular tunic (iris, ciliary body, choroid)and nervous tunic (retin a)and its adnexa i.e. eyelids, lacrimal apparatus, extraocular muscles, conjunctiva and other soft tissue are very important structure for proper functioning of eye. The embryonic tissue which contributes for development of eye and its adnexa are:
1. Surface ectoderm of the head: Lens, corneal epithelium, eyelids, Lacrimal gland and conjunctival epithelium
2. Neural ectoderm of the forebrain: Retina, Posterior epithelium of iris and ciliary body, optic nerve
3. Mesoderm: Cornea stroma, Descemet’s membrane, Choroid, Sclera, extra-ocular muscles
Development of eye begins simultaneously with the development of brain by the process of neurulation. Neural tube is lined by neuroectoderm and the exterior of embryo lined by surface ectoderm. Neural crest cells, population of specialized mesenchymal cells develop from the lateral border of the neural fold and do not participate in the formation of neural tube. These neural crest cells migrate under the surface ectoderm peripherally and populating the region around the optic vesicle and form the future all connective tissue of structure of eye.
Formation of optic vesicle and optic cup which develop the retina
The optic sulci are visible as paired evaginations of the forebrain neural ectoderm on day 13 of gestation in the dog. The outpouching on either side of optic field of diencephalon (caudal part of prosencephalon) called optic vesicle which attached to the diencephalon by optic stalk. In dog, it appears at the gestation age of day 15. Each optic vesicle grows laterally until it comes into contact with the surface ectoderm. The surface ectoderm become thickened to form the lens placode near the optic vesicle. This lens placode invaginates into the optic vesicles and form lens vesicle, which later on loses it contact with the surface ectoderm. Simultaneously, the optic vesicle invaginates to form double layered optic cups. The neuroepithelial cells of inner layer of the optic cups proliferate and

ABSTRACT

Future is the era of ICT (Information Communication Technology) which is equally applicable in the field of Agriculture. Farmers database will be an important part of ICT which is required for smooth functioning of various agricultural activities like Farmer’s Trainings, Demonstrations, Crop monitoring, Support to farmers, implementation of various government schemes etc.  This software records farmers Name, Phone number, Sex, Category (SC/ST/Gen),  Number of dependents, Annual agricultural income, whether fully or partially dependent, Land holding size,  Major crops, Village, Block, Sub-division, Land situation (Plains/ Low Hills/ Mid Hills/ High Hills), Soil Reaction, Soil type, (Highly Acidic/Moderately /acidic/Neutral/Alkaline/Highly Alkaline), NPK status, Irrigation facility and information regarding Cattle. From the above record various reports can be generated according to the needs of the scientific personnel. For example soil scientist will have record of soil pH & NPK status of different farmers across the district. Scientist can filter the database to get farmers of a particular soil type to conduct training;

Introduction
The mammalian embryos are subdivided into two groups namely domestic animals where extraembryonic membranes form by folding process, and primates where blastocyst implants very soon after it enters the uterus and extra embryonic membranes forms after implantations. The major function of fetal membranes is to provide nutrients to developing fetus, protection, synthesis of enzymes and hormones and caring of fetal waste products. It is consisted of yolk sac, amnion, allantoic and trophoblast or chorion. The trophoblast is the single most important tissue of fetal membranes which has potential role in absorbing, transmitting and handling nutritive and waste products.
Yolk sac
It is a primitive structure. Develops early in the embryonic period from the entoderm which disappears after short period of time in ruminants. The uterine milk, secreted by the endometrial glands, is absorbed by the blastocyst along with yolk sac to provide nutrition to early embryo. Before forming other embryonic membranes yolk sac performs limited functions whose role is limited during mid and late gestation.
Amnion
It is an ectodermic vesicle that arises from an out folding of the chorion which is a double walled sac that completely surrounds the fetus except at the umbilical ring. The inner layer of this double-walled sac is the “true amnion” and the outer layer is the “false amnion” amnion chorion. Like yolk sac, the amnion chorion also lasts for shorter period.The amniotic fluid is clear, colorless and mucous in nature. Source of amniotic fluid: In early to mid-gestation, it is probably from the amniotic epithelium and from fetal urine as the fluid is quite watery. As gestation advances, the allantoic fluid increase in volume while the amniotic fluid volume remains fairly static but

Fish forms an integral component of the Indian food basket and it is more so for the population living in the eastern and north eastern States of India. The eastern states of India include States such as West Bengal, Bihar, Jharkhand and Odisha. As per a current estimate of 2023 (https://www.indiacensus.net), approximately a population of 31.66 crore, i.e. 22.15% of the country’s total, live in these four States. Due to the suitable geographical terrain, these states have been bestowed upon a large number of riverine stretches, a large number of natural reservoirs of varied sizes, beels and floodplain wetlands, and a huge plain terrain supporting ponds and tank resources. Due to the very nature of the land and the popularity of fish among the populace, these eastern Indian states have also served as the main stage for the development of fisheries and aquaculture during the last centuries in the country. Further, many of the epoch making technologies for the development of fisheries in the inland waters as well as aquaculture in the ponds have originated from this region.

Principle
Jam: Jam is a product made by boiling the fruit pulp with a sufficient quantity of sugar to reasonable consistency, firm enough to hold fruit tissues in position. Apple, pear, sapota, apricot, carrot etc. are used for preparation of fruit jam. Jam contains 0.5-0.6 % acid and invert sugar should not be more than 40 %.
Total soluble solids (TSS)
The TSS value is defined as the amount of sugar and soluble minerals present in fruits and vegetables. A refractometer is based on the principle of total refraction. This is done by placing a few drops of distilled water on the prism in the specimen chamber of the back the cover. The distilled water reading should be zero. If it is not so, it should be set to zero with the scale correction knob. The specimen chamber is now cleaned with muslin cloth or tissue paper. For determining the TSS, a drop of sample (jam, juice and syrup, etc.) is placed on the prism and the percentage of dry substance in it read directly on scale in refractometer.

Principle
Jelly: Jelly is a semi-solid product prepared by boiling a clear, strained solution of pectin containing fruit extract, free from pulp, after the addition of sugar and acid. A perfect jelly should be transparent, well set, but not too stiff, and should have the original flavour of the fruit. It should be of attractive colour and keep its shape when removed from the mould. Pectin (0.5-1.0%), acid (0.5-0.75%), sugar (65%), and water are the four essential ingredients. Pectin test and determination of end-point of jelly formation are very important for the quality of the jelly. Some recipes for jelly making are given below:

Principle
Nectar: The term ‘fruit nectar’ is used to designate pulpy fruit juice blended with sugar syrup and citric acid to produce a ready-to-drink beverage. In this fruit beverage contains at least 20% juice/pulp and 15% total soluble solid and also 0.3% acid. It is not diluted before serving. Many fruit juices are either too acidic or strongly flavoured; these cannot be pleasant without dilution of blending or both. These strong, tart juices are delicious after dilution with thin syrup or blend juice e.g. apricot, guava and plum juice. Out of the tropical fruits, nectars made from banana, guava, mango and papaya are quite popular. The product is sealed in container or glass bottles and processed by heat to prevent spoilage. The fruit ingredients may be puree, pulp, juice or concentrated equivalent to 40 percent of the finished products. Apples, cherries and pineapples are used in combination with others fruits. The sweeteners are sugar, invert sugar syrup, dried corn syrup, glucose syrup and the optional ingredients are lemon juice, citric, malic and fumaric acids as acidifier and ascorbic acid as antioxidants (150 ppm) can be used.

Principle
Squash: A fruit juice squash essentially consists of juice containing moderate quantity of fruit pulp to which cane sugar is added for sweetening e.g. orange squash, plum squash. This is a type of fruit beverage containing at least 25 percent fruit juice/pulp and 40-50 percent total soluble solids, commercially. It also contains about 1.0 percent acid and 350 ppm SO2 or 600 ppm sodium benzoate. It is diluted before serving.
Mango, orange and pineapple are used for making squash commercially. It can also be prepared from lemon, lime, guava, pear, apricot, muskmelon, papaya etc., using potassium metabisulphate (KMS) as preservative, or from jamun, passion fruit, peach, phalsa, mulberry, raspberry, straw berry, grapefruit etc., with sodium benzoate as preservative.

2.1 Introduction

Greenhouses are used mainly for cultivating vegetables and fruits during the off-season to provide favorable growing conditions. Proper management of the greenhouse structure is necessary to create these off-seasonal favorable conditions for plants. Factors like site selection, location, atmospheric conditions, cropping pattern, and structure of the greenhouse are considered during the development of a greenhouse. The National Committee on the use of Plastics in Agriculture (NCPA-1982) suggests conducting site-specific greenhouse technology trials before implementation across the nation.

Introduction
Cardiovascular system consists of heart and blood vessels which include both arteries and veins. The formation of blood vessels occurs in two stages-vasculogenesis and angiogenesis. Blood islands are formed on the yolk sac by clusters of mesodermal cells. Vasculogenesis i.e., formation of blood vessels starts during third week of gestation in the blood islands. It starts first in the yolk sac and later in the allantois. Angiogenesis describes budding and sprouting of new vessels from the existing vessels. The adult heart is a modified blood vessel. The cardiogenic plate lies ventral to the pericardial coelom in the third week gestation. The position gets reversed with the forward growth of the head and folding of the embryo. Two endocardial tubes appear by the end of 6 to 7 somite stage which fuse to form the primitive heart in the 8 to 9 somite stage. The parts of the endocardial tube are- sinus venosus, atrium, ventricle, bulbus cordis and truncus arteriosus. The four chambered heart is formed by the formation of endocardial cushions, interatrial septum, interventricular septum and spiral septum. The interatrial septum includes the formation of septum primum and septum secundum. Oxygenated blood from the placenta enters the embryo by a large umbilical vein which enters the liver of the developing embryo. It is conveyed to the posterior vena cava through ductus venosus. The blood from the vena cava enters the right atrium which is sent to the left atrium through foramen ovale. Blood then enters the left ventricle and transmitted to all the parts through the aorta) The umbilical arteries arising from the aorta transport blood to placenta for oxygenation. After birth, lungs become functional as the placental circulation ceases. The formation of arterial system involves the modification of aortic arches, ventral aorta, dorsal aorta and its dorsal, ventral and lateral branches. Aortic arches appear sequentially and connect cranial portions of dorsal aorta with ventral aorta)The venous system is derived from the remnants of the cardinal system and vitelline veins and to a lesser extent the umbilical veins.

Initially, exploitation of heteosis was confined to corn and a few other open- pollinated crops but presently heterosis is being exploited practically in all species cutting across mode of reproduction. More and more evidences are emerging that heterotic expression in a cross is a function of genetic backgrounds and genes. Heterotic grouping would remain a key strategy in management of diverse genetic backgrounds and genes for full exploitation of heterosis. The commonly used methods in developing hybrids in self- pollinated crops are listed and explained as follows:

Manual emasculation and Pollination Method

In this method, female parent flower buds are emasculated manually and the emasculated buds are pollinated by the pollen grain collected from protected flowers of the male parent. This method is effective and successful where the crossed fruits produce plenty of seeds and the seed requirement for planting the commercial hybrid seed is much less. Consequently, this method is being used in a routine manner on a commercial scale in vegetable crops mostly by private sector seed companies in India and south-east Asian countries. The crops covered under this method of hybrid seed production are as follows:

Tomato, hot-pepper, sweet pepper, eggplant, okra, bottle gourd, bitter gourd, ridge gourd, smooth gourd, cucumber, pumpkin, water melon and muskmelon. Cucurbits are included here as although they are cross-pollinated but behave like self-pollinated crops in terms of almost no inbreeding depression.

Introduction
The integumentary system is a vital organ system in animals, encompassing the skin, hair, nails, and associated glands. This complex system is essential for protecting the body, regulating temperature, providing sensory information, and facilitating communication among individuals. The development of the integumentary system is a remarkable evolutionary adaptation that reflects the diverse environmental challenges faced by different species. The integumentary system has evolved to meet the specific needs of various species, playing a crucial role in survival. As organisms transitioned from aquatic to terrestrial environments, the integument had to adapt to prevent dehydration, protect against UV radiation, and manage temperature fluctuations. For example, the development of a thicker, keratinized epidermis in terrestrial animals minimizes water loss and provides a barrier against environmental stressors. In mammals, the integumentary system exhibits even greater complexity. The evolution of hair, fur, and other adaptations allows for enhanced thermoregulation, sensory perception, and social interaction. For instance, many mammals have evolved specialized hair types, such as the insulating undercoat found in Arctic species or the short, coarse hair of desertdwelling animals that aids in heat dissipation. Anatomical Structure The integumentary system is composed of several key components: the epidermis, dermis, hypodermis (subcutaneous layer), and associated appendages such as hair follicles, sebaceous glands, and sweat glands.
1. Epidermis: The outermost layer of the skin, the epidermis, is primarily composed of keratinocytes, which produce keratin, a protein that provides strength and waterproofing. Melanocytes, located within the epidermis, produce melanin, the pigment responsible for skin color. The thickness of the epidermis varies significantly among species, with adaptations reflecting the ecological niches of each animal.

1. Introduction

Jackfruit is a fruit crop that is under appreciated and neglected. The jackfruit (Artocarpus heterophyllus Lam.) is a member of the Moraceae family. India is the world’s greatest cultivator and producer of jackfruit, also known as the poor man’s fruit because it grows more in rural than metropolitan areas. It is a pretty huge tree that bears the world’s largest edible fruit. The jackfruit is a tropical fruit native to Southeast Asia. It is thought to have originated in India’s rainforests, in the Western Ghats, and is now widely farmed throughout the region’s lowlands. The leading jackfruit producers in the world include Bangladesh, India, Myanmar, Nepal, Thailand, Vietnam, China, the Philippines, Indonesia, Malaysia, and Sri Lanka. Jackfruit can be found in East Africa, Brazil, and Caribbean nations such as Jamaica. Bangladesh’s national fruits are the jackfruit, mango, and banana.

Introduction

A marketing plan is a strategic document that guides an organization in generating leads and engaging with target customers. It serves as a roadmap for how a company will approach the market, akin to a job description for the business. Every organization needs a well-crafted marketing plan that is tailored to its specific objectives, regularly updated, and aligned with customer demands. Companies with a solid marketing plan tend to be more successful and outperform their competitors compared to those without one.

The marketing plan outlines a strategy for growth by detailing how a company will attract and retain customers. It is an integral part of the overall business plan and lays the foundation for future market opportunities. A strong marketing plan focuses on customer needs and provides a clear roadmap for launching new products, expanding the customer base, and boosting the company’s profile. It includes essential elements such as business goals, mission, budget, and strategies. A well-designed marketing plan ensures effective promotion of products and services, helping businesses reach their target market and track success. Moreover, it should be flexible and adaptable to the evolving market landscape.

Principle
Pickle is an edible product preserved and flavoured in a solution of common salt and vinegar. Spices and oil are also added. They add to palatability of a meal, aid in digestion and are good appetizers too. Pickles are prepared from fruit and vegetables like cauliflower, reddish, carrot, green chili, turnip, cabbage, onion, mango, jackfruit, aonla and lemon etc. Commercial preservation of many pickle relied upon conversion of fermentable carbohydrates by lactic acid bacteria to organic acids during bulk storage and/or the addition of sufficient amount of sugar, vinegar and other ingredients to the fully cured and packed products to preclude any microbial growth. Organic acids, oil, salt and spices all have antimicrobial properties at suitable concentration especially in combination which preserves the pickles. Pickles in brine such as or after fermentation however, need some amount of preservative or pasteurization to prevent the spoilage.

Materials required
Material : Wheat Flour (550 g), Pearl millet Flour (50 g), Ragi Flour (50 g), Finger millet Flour (50 g), Barley Flour (50 g), Sorghum Flour (50 g), Foxtel Millet Flour (50 g), Maize Flour (50 g), Oat Flour (50 g), Besan (50 g) Shortening (350 g), Fine Sugar (400 g), Sodium bicarbonate (10 g), Distilled water (50 ml), salt (8 g). Equipments: Mixer, rolling pin, Tray, cookies cutter, baking oven etc. Principle: Cookies are made from soft wheat are having high sugar and fat content. They contain relatively low moisture content and have fairy high shelf life. Biscuits are similar name used in Europe and UK. Cookies are chemically leavened. Sugar and shortening are creamed to form dough with flour and leavening agents. When cookies dough enters the oven, the fat starts melting and sugar is dissolved which allow the cookies to spread as a function of gravity. The leavening agents expand it in all direction and structure is stabilized with high temperature prevailing in the oven.

Introduction
• Overview of the development of the musculoskeletal system, including bones, cartilage, joints, and muscle types within skeletal and cardiac systems.
Development of the Musculoskeletal System
Mesoderm Contributions
• Mesodermal Derivatives
• Gives rise to skeletal muscle, skin dermis, endochondral bones, and joints.
• Notochord and Somite Formation
• The notochord induces the paraxial mesoderm to form somites, with somitomeres developing rostrally to the notochord in the head)
• Somite Differentiation
• Each somite differentiates into three regions:
• Sclerotome (medial): Forms most of the axial skeleton (vertebrae, ribs, base of the skull).
• Dermatome (lateral): Migrates to form the dermis of the skin.
• Myotome (middle): Migrates to form skeletal muscles. Individual adult muscles arise from the merger of adjacent myotomes.
Muscle Development
• Origins of Muscle Tissue:
• All skeletal muscle derives from paraxial mesoderm forming somites and somitomeres, with the exception of iris musculature (derived from optic cup ectoderm).
• Cardiac and smooth muscles originate from splanchnic mesoderm.
