ABSTRACT

Cultivation of mat grass (Cyperus pangorei Rottb.) is valuable and expensive products can plays an important role in rural areas such as Sabong and Pingla in Paschim Medinipur of West Bengal in India. Mat grass plays an act to fill the empty employment field to the resource of poor farming community to support and secured their livelihoods and maintain the economical balance of their area. This grass usually cultivated by the poor and marginal farmers. The mat sticks are used to make various household utility items, such as floor and bed mats and other attractive goods like bags, purse, TV covers. Now a days the products prepared from this grass is exported to different countries. Mat sticks are attractive durable and is eco-friendly substances which easily gets decomposed by organisms, does not create any environmental hazards and gets more profit as compared to growing rice per annum. Even an old man or woman in rural areas can earn a net income of about Rs.120 to Rs150 per day. Major focus of the study is to establish the scientific principles behind processing, separation of clum strand, texture and strength properties of the mat fibers and increase mat production which leads to improve the economic condition of rural people.

Since time immemorial India has been leader in respect to spice, area, production and consumption. India is known as ‘Land of spices. Out of 109 spices listed by the ISO, India produce as many as 63 owing to its varied agroclimatic regions. Almost all the state and union territory of the country grow one or the other spices. Spices are the sources of livelihood and employment for large number of people in the country. Seed spices are annual herbs, whose dried seeds or fruit are used as spices. Spices are the nature’s gift to mankind and since antiquity, spices have been considered indispensable in the culinary art, as they are used to flavour foods and beverages The important seed spices are coriander, cumin, fennel, fenugreek. ajwain, dill,, celery, anise, nigella and caraway. The other seed spices s are poppy seed, rai, yellow mustard, white mustard, parsley and sesame. In India, Rajasthan and Gujarat has emerged as “Seed spice bowl” and together contributes more than 80 percent of total seed spices.

Burgeoning population exerts pressure on limited precious natural resources for enhancing production of food, fodder and fuel. In order to meet out increasing demand for food, fruit, vegetables, oilseeds, fodder and timber wood for burgeoning population, it is necessary to utilize each unit of natural rsesource very efficiently. The productivity of the precious natural resources is to be enhanced per unit time per unit area by agronomic ally managing stresses soil and land ecosystem to harvest more benefit. The cropping system as well as intercropping system practised by using different trees, fruits, vegetables, crops are the very efficient enterprises for realising higher productivity of natural resources available with in specified ecosystem.

Strawberry (Fragaria vesca) is an important fruit crop in India and its commercial production is possible in temperate and sub-tropical areas of the country. According to the Ministry Agriculture, Government of India estimates, production of the fruit in India has dropped by 40% from 8,000 metric tonnes in 2014-15 to around 5,000 metric tonnes in both 2015-16 and 2016-17. Strawberries mainly consist of water (91%) and carbohydrates (7.7%). They contain only minor amounts of fat (0.3%) and protein (0.7%). The nutrients in 100 gm of raw strawberries are, calories 32, 91% water, 0.7gm protein, 7.7 gm carbohydrate, 4.9 gm sugar, 2 gm fiber and 0.3 gm fat. Strawberries should not lead to big spikes in blood sugar levels and are considered safe for people with diabetes. It is also useful for weight loss and can help prevent many diseases.The most abundant vitamins and minerals in strawberries are, vitamin C, vitamin B9, potassium and manganese. To a lesser extent, strawberries also provide iron, copper, magnesium, phosphorus and vitamins B6, K and E.

e-Governance can be defined as the application of information and communication technology (ICT) for providing government services, exchange of information, transactions and integration of previously existing services and information portals. The "e" in e-Governance stands for 'electronic'.

e-Governance refers to the use of Information and Communication Technology (ICT), particularly web-based applications, to provide access to and deliver information/service to the public, businesses, other agencies and governmental entities faster, cheaper, easier and more efficiently.

The Council of Europe referred to e-governance as: "The use of electronic technologies in three areas of public action

Introduction

Fish serves as a particularly significant source of protein and important micronutrients for all demographic groups in the population, and it is also a cheap and accessible food. A significant portion of the populace relies on f ish resources (both marine and inland) for sustenance, employment, and income. In India, thousands of people have relied on the fish trade as a source of income, with women making up the majority of fish vendors. Contrary to men, whose work is primarily restricted to the sea, river, or lake, fisher women vendors must travel with their goods to markets.

Introduction

Soil erosion is becoming a global challenge, causing various effects such as reducing crop yields, degradation of water quality, leading to inundation, degrading land by making it unsuitable for agriculture and others. Moreover, it is a significant problem that poses a devastating impact on food security, livelihoods, and the environment. It not only depletes the fertile soil needed for agriculture but also leads to reduced agricultural productivity, loss of biodiversity, and increased vulnerability to climate change.

Introduction

Financial markets play a critical role in the health and stability of a nation's economy. They act as a complex network where individuals, businesses and governments can exchange financial instruments, facilitating the flow of capital and fostering economic growth. According to the World Bank, the global stock market capitalization reached a staggering $93 trillion USD in 2022, highlighting the vast pool of resources circulating within these systems. At the heart of financial markets lies the ability to connect those who possess capital with those who require it (Karpova et al?, 2020). Companies seeking to expand their operations can raise funds by issuing stocks or bonds, essentially selling a piece of ownership or a promise to repay a loan with interest. Investors, on the other hand, can utilize these markets to put their money to work, seeking returns on their investments through dividends, interest payments, or capital appreciation. This efficient allocation of resources fuels economic growth by enabling businesses to invest, innovate and create jobs.

Introduction
Experimental physiology is a fundamental aspect of medical, veterinary and biological sciences that seeks to understand how living systems function through controlled experiments. It plays a crucial role in exploring the mechanisms behind normal and abnormal physiological processes. With roots in ancient medicine, experimental physiology was notably advanced by Claude Bernard in the 19th century, who introduced key concepts
like homeostasis and experimental methods that are still in use today. The interdisciplinary nature of this field connects it with disciplines such as biochemistry, pharmacology, and bioengineering, promoting a more comprehensive understanding of biological processes.
Investigating Physiological Processes
Experimental physiology aims to explore how organisms function at the cellular, molecular, organ, and systemic levels. This field investigates both normal physiology and the mechanisms behind diseases, offering insights into how organs and systems interact. Laboratory-based experiments are central to this learning process, allowing students and researchers to apply theoretical knowledge to practical scenarios. By observing how
tissues, organs, and entire systems respond to stimuli, experimental physiology enables the exploration of the relationship between structure and function in biological organisms. The practical experience gained in the lab is critical for medical and veterinary education, as theoretical knowledge alone is insufficient. In fields like physics and chemistry, materials can often be stored for future use. However, in biology, especially physiology, fresh
live tissue is often needed for fundamental experiments. For example, muscle and nerve tissues require careful handling and immediate use after isolation to study their responses to electrical stimuli. In in vivo experiments, live organisms are studied in their natural context, while in vitro studies use isolated cells, tissues, or organs to understand their behavior in a controlled environment.

Abstract
Environmental pollution, resulting from both human activities and naturalm factors, is escalating as a consequence of population growth, industrial expansion, and urban development. Bioremediation is a method used to clean up polluted soil and water by using natural helpers like microorganisms, fungi, and plants. Bioremediation is a biological technology which offers cost-effective and low-pollution methods that can be applied directly at contaminated sites for addressing specific types of contamination. This technique uses microbes to break down pollutants and plants to absorb or stabilize harmful substances, especially heavy metals. As pollution becomes a bigger issue, bioremediation offers a promising way to tackle it and help restore damaged ecosystems. Bioremediation can be a more cost-effective solution compared to other technologies for cleaning contaminants, while also minimizing potential risks to human health and the environment. This chapter provides an overview of the current status of bioremediation and highlights its potential areas of application.

ABSTRACT

The use of engineered nano-materials has been increased as a result of their positive impact on many sectors of the economy including agriculture. Silver nanoparticles (AgNPs) are now used to enhance seed germination, plant growth and as anti-microbial agents to control plant diseases. This study investigated the synthesis of silver nanoparticles using the aqueous solution of three medicinally important plants (such as Spondius mombin L., Stachytarpheta jamaicensis (L.) Vahl and Syzygium samarangense (Blume) Merr & Perry leaf extract in room temperature (350C). AgNPs present in the leaf confirmed by colour change, UV-VIS spectrum analysis, average size of AgNPs confirmed by PAS. FTIR measurement were carried out to identify the other possible biomolecule groups such as alkenes, esters, phenols, alcohols and aromatic. Leaf extract AgNPs were shown significantly higher antimicrobial activities against four species of bacteria. This findings suggest that the seed germination percentage, relative seed germination rate, relative shoot and root growth and germination index of the tested plant depends upon concentrate gradient of AgNPs.

Introduction

This chapter gives first hand information on PCR for beginners. PCR is used to amplify a short, well-defined part of a DNA strand. This can be a single gene, or just a part of a gene. As opposed to living organisms, the PCR process can copy only short DNA fragments; usually up to 10 kb (kb stands for kilo base pairs). Certain methods can copy fragments up to 40 kb in size, which is still much less than the chromosomal DNA of a eukaryotic cell-for example, a human cell contains about three billion base pairs (Kary Mullis, 1983).

Tamil Nadu has unique physiography with western and eastern Ghats on the west and northwest, Bay of Bengal in the east and Indian Ocean to the south. Tamil Nadu has high dependence on natural resources and hence faces the threat of climate change and its impacts. Available evidence shows that there is high probability of increase in the frequency and intensity of climate related natural hazards (Stephen, 2012). Out of 13 million hectares of geographical area, about 7 million hectares of land is under cultivation. Of this 55 per cent is irrigated and rest is under rain fed / dry lands. In Tamil Nadu, ground water has been harnessed fully and dry land productivity is found oscillating with ruling variability in seasonal monsoon rain and hence agricultural productivity is always under stake.

10.1 Introduction

Biomass fuels are a potential source of renewable energy. One of the major barriers to their widespread use is that biomass has a lower energy content than traditional fossils fuels, which means that more fuel is required to get the same amount of energy. When combined — low energy content with low density -the volume of biomass handled increases enormously. Compaction or densification is one way to increase the energy density and overcome handling difficulties.

Densification means compaction of loose material or to increase density of loose biomass so that its volumetric efficiency can be increased. Densification essentially involves two parts; the compaction under pressure of loose material to reduce its volume and to agglomerate the material so that the product remains in the compressed state. The resulting solid may be a briquette, a pellet and a cube. It will be briquettes if roughly, it has a diameter greater than 30 mm. Smaller sizes are normally termed pellets though the distinction is arbitrary. The process of producing pellets is also different from the typical briquetting processes. The densified product can be developed in the cubical shapes as well.

If the material is compacted with low to moderate pressure (0.2-5 MPa), then the space between particles is reduced. Further, increasing the pressure will, at a certain stage particular to each material, collapse the cell walls of the cellulose constituent, thus approaching the physical, or dry mass and more, density of the material. The pressure required to achieve such high densities are typically 100 MPa plus. This process of compaction is entirely depending on to the pressure exerted on the material and its physical characteristics including its moisture content.

Introduction

Indigenous Technological Knowledge (ITKs) refers to the knowledge that acceptable to all as absolute hearing and developed about the meticulous altitude by the people irrespective of gender that is women and men ancient to an a specific geographical area. This ancient technological knowledge that humans in an accustomed association accept developed over time and abide to advance it, is predicated on animal kingdom adventures on accumulation scale, activating and changing, activated throughout a lot of cases over centuries of use. Highest accessible knowledge to bounded knowledge and ambiance and put greater weightage on abbreviate risks instead of maximizing profit. The traditional technological knowledge (ITKs) covers a complicated sphere of subjects, viz. crop production, livestock rearing, accustomed knowledge management, ailment preparation, healthcare, insect administration, and others. The utilization of non-chemical methods for protecting lives and crop aegis is already accepting in several countries including India. The administration strategies developed and answer by the Governments is now supported the utilization of plant extracts. If an accomplishment is fabricated arise the cultivation of Indigenous Technological Knowledge (ITK) based articles on the small scale, it is often an economically applicable advantage for the appropriate development of eco-friendly chemicals.

Indian agriculture has been started over 10,000 years old, over millennia, farmers developed innumerable practices to auspiciously abound crops and accession animals within the awful adapted agro ecological regions of the Indian subcontinent. About 170 years of acceptance brought in new techniques, some advantageous in addition to a few harmful event of ancient Technological knowledge (ITK) systems, including administration of accustomed environment, has been a bulk of adaptation to the humans who generated these systems continued aback. Million of ITKs were supported to avail knowledge of actual and living assets to construct sure basal livelihoods for bounded people.

Although women work in household chores, agricultural activities, factories, and different workplaces in days of yore, their valuable work is still not recognized as a financial entity (Kathrivel and Sivakumar, 2003). The multiple roles performed by ‘Nari shakti share many working hours, but financial terms are off the records. Women’s power at construction work is greater utilization as labour and their daily routine employment. 

Introduction

Aquaculture production is mainly reliant on the availability of high-quality seed and achieving mass production of superior juveniles is impeded by limited knowledge regarding their nutritional needs. Moreover, understanding the physiological aspects of larval nutrition is imperative for effectively substituting live food with inert micro diets. In India, the hatchery survival rate of carp larvae remains relatively low at around 40% (Warnecke and Pluta, 2003). The primary cause of this early larval mortality can be attributed to insufficient knowledge of the larval nutrient requirements and challenges in managing the transition to exogenous feeding.

1.1 Introduction Rural women worldwide grapple with many challenges, ranging from restricted access to essential resources and limited educational opportunities to constrained pathways for economic advancement. Extensive research conducted by the World Bank has illuminated the persistent struggles faced by rural women, emphasizing disparities in education, healthcare, and economic opportunities (World Bank, 2019). Simultaneously, UN Women underscores the systemic hurdles perpetuating gender inequalities, necessitating urgent and comprehensive solutions (UN Women, 2020).

Amidst these challenges, emerging technologies stand as a transformative force with the potential to reshape the trajectories of rural women. Recognizing this potential, the International Telecommunication Union (ITU) emphasizes the capacity of technological interventions to ameliorate challenges faced by women in rural areas.

1.1 Introduction

The human population is growing rapidly at an alarming rate, disproportionately to the production of food supplies, which will necessitate production of more food in the near future. The human population has already crossed the 7 billion mark and is expected to rise over 8-10 billion by 21st century. More than 800 million people are reported to suffer from malnutrition (Matson et al., 1997).  Thereby necessitating the need for more food production. Presently, agriculture faces the double challenge of feeding a fast growing population and at the same time prevents the degradation of the agricultural resource base. There appear to be two options for developing countries; either to improve agriculture through modernization, by emphasizing pesticides, fertilizers, machinery and modern varieties of crops; or use sustainable agriculture, promoting improved traditional, small-scale techniques (Pretty, 1999).

Introduction  

Developing effective strategies for improving and stabilizing rainfed crop production continues to be a prime concern in the semi-arid region of western India. Rain water management is most crucial aspect in rainfed production systems. Growing uncertainties associated with rainfall pattern (Ali et al., 2007) add to the complexity of the challenge. The medium deep black soil region of Rajasthan is spread predominantly in Jhalawar, Kota, Baran, Bundi, and Sawai Madhopur districts of South-eastern Rajasthan (Fig. 1). This region is characterized by almost flat alluvial plains interspersed with hills of Arawali and Vindhyan ranges and rock outcrops.
