Brief History

Fondness of man for rabbits is well established by its appearance in the Aesop’s fables and Vishnu Sharma’s ‘Panchtantra, both of which date back to 2nd century B.C. However, domestic rabbits are descendents of wild species of Western Europe and North Western Africa where Oryctolagus still exists. Interestingly, it was the Romans who first raised rabbits in leporaria (enclosed warrens) as a game animal. Like Spaniards, Romans also ate fetuses of newborn young ones whom they called laurices. These leporaria ultimately paved the way for development of game parks in the Middle Ages. The monks ate laurices during Lent because they were an aquatic dish.

Computer Purchase

With so many factors to consider, deciding which omputer to buy can be a real challenge. From components to software to accessories, new PCs offer a bewildering array of choices. Sifting through the large number of options can be a daunting task. Almost any PC on the market today can more than adequately handle such standard office chores as word processing and spreadsheets, as well as basic Internet functions like e-mail and general browsing. If you want to edit digital video or manage a large database, however, you may need more than the basics.

The best way to pay only for what you need is to carefully consider what you want to do with your system now, and try to anticipate what might interest you next 2-3 years. Specific applications call for certain types of hardware, whether at home or in the office. When you’re ready to buy a computer, here are some recommendations for the average user’s basic requirements:

Abstract

The anomalies observed in the reverine systems have been demonstrated to be the potential tool in deciphering the tectonically active zones. Such various drainage anomalies viz: radial drainages, anomalous compressed meanders, eyed drainage and the youthful floodplains observed in Annamali – Palani - Varushanad hill ranges of the Western Ghats of Tamil Nadu show that the N-S and NE-SW trending faults are tectonically active in the recent years.

Healing of fracture is a consequence of cellular behaviour in a living organism and as such can be modified by almost all endogenous or exogenous factors that affect the metabolic function of cells. These factors include transforming growth factor-β, bone morphogenetic proteins, hormones, vitamins and prostaglandins. The anabolic hormones like thyroxine and insulin accelerate bone formation in experimental animal. Hence, this chapter is proposed to evaluate the effects of thyroxine and insulin therapy in the management of tibial metaphyseal fracture in dogs.

Clinically healthy, adult mongrel dogs (15) of either sex are randomly divided into three groups (A₁, A₂ and A₃) of 5 animals each. In all the animals, unilateral metaphyseal fracture is created in the proximal tibia and then immobilized with cross intramedullary pinning with interfragmentary wiring under thiopental (5%) anaesthesia. All the animals are administered broad-spectrum antibiotic (streptopenicillin @ 1 g intramuscularly /dog/day) and analgesic (5 ml I/M daily) and surgical wounds are dressed daily with Povidone iodine and Lorexane cream for 5 days postoperatively. In group A₂, thyroxine sodium tablets (0.013 mg/kg body wt, orally) and in A₃, insulin injection (2 IU/kg body wt, s/c) are given on day 7 and then on every alternate day till day 45 postoperatively, at one specific time. Group A₁, is remained as control, in this group no hormonal therapy is given.

Craniocaudal and mediolateral radiographs of the fracture site are taken immediately after surgery and subsequent on days 15, 30, 45 and 60 postoperatively. The radiographs are observed for status of fracture reduction and fixation immediately after surgery and subsequently for the maintenance of reduction, progress of fracture healing and complication, if any, at different intervals.

Iron Toxic Soils

Lowland rice is being cultivated on approximately 128 million hectares of either irrigated or rainfed land out of which 100 million hectares suffer due to nutrient deficiency or toxicities. Among the toxicities, iron toxicity is well recognized as a nutritional disorder in low land rice production. Iron toxicity is a syndrome of disorder associated with high concentration of Fe²⁺ in soil solution. A wide range of soil types show iron toxicity problem including acid sulphate soils, acid clay soils, peat soil and valley bottom soil. During monsoon rains in the wet season, soluble iron (Fe²⁺) migrate to the surface and its iron content increases to subtoxic or toxic levels.

In rolling topography and with heavy monsoon downpour there is considerable lateral flow of iron containing water from the adjacent uplands to mid – and low lands. This increases the iron content to toxic levels. Poorly drained sandy soils in valleys receiving interflow water from adjacent uplands with laterite horizon (Plinthudults) showed iron toxicity in Srilanka and Kerala and Odisha in India. These soil groups come under the taxonomic orders Alfisols, Ultisols and Oxisols occurring in association with Entisols and Inceptisols. The iron concentration (Fe²⁺) in soil solution that affect low land rice yield ranges from 10 to > 2000 mg L^-1 Iron toxicity induced yield reduction which is associated with poor nutrients . status (deficiency of P, K and Zn) and H₂S toxicities.

Introduction

Climate variability can have significant impacts on agricultural production, affecting both the demand and supply sides of farming. As climate change continues to negatively impact our ecosystem, food production, and human livelihood, this topic has gained widespread attention from researchers and academics worldwide. Given that agriculture is highly dependent on factors such as precipitation and temperature, it is considered one of the most climate sensitive sectors (Sagar et al., 2022).

Climatic data is complex and nonlinear, with significant fluctuation across time components, resulting in greater volatility. This means that stochastic climatic variables, including rainfall, temperature, relative humidity, and other weather parameters, often exhibit conditional heteroscedasticity, leading to irregular residual mean and variance across time series.

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.

Introduction
Antimicrobial resistance (AMR) is rapidly emerging as one of the most critical global health challenges of the 21st century. Antimicrobial resistance can be defined as a condition in which microbes develop resistance against the spectrum of conventional antibiotics, also known as multidrug resistance and these microbes are typically known as drug-resistant pathogens. The infections associated with antibiotic resistant pathogens are usually accompanied by substantial morbidity and mortality along with the massive economic burden on global healthcare, which causing approximately 4.95 million deaths globally each year. The prevalent issue is largely attributed to the repercussions of antimicrobial overuse or irresponsible utilization across diverse contexts, predominantly in clinical treatment, agricultural practices, animal healthcare, war crisis and the food system and a lack of regulation in their supply. Nature has long been a rich reservoir of biologically active compounds with diverse chemical structures and pharmacological properties, offering valuable resources for treating a wide array of diseases. In recent years, the rising threat of antimicrobial resistance has renewed global interest in natural products as promising sources for novel antimicrobial agents. Among these, plant-derived phytochemicals, microbial metabolites, marine bioactive compounds, and animal-based substances have shown significant potential in combating drug-resistant pathogens. These natural compounds exhibit unique mechanisms of action that can overcome existing resistance pathways, making them important candidates in the development of nextgeneration antibiotics. From alkaloids and flavonoids in medicinal plants to secondary metabolites produced by actinomycetes, antimicrobial peptides from animals, and complex molecules derived from marine organisms, nature offers a vast and largely untapped arsenal of antimicrobial agents. Exploring and harnessing these natural resources presents a sustainable and innovative strategy to address the growing global crisis of antimicrobial resistance. The enormous potential of natural products in the fight against antibiotic resistance is examined in this chapter. The different kinds of bioactive chemicals, their modes of action, and the creative approaches being used to maximize their medicinal potential are highlighted.
Challenges in Addressing AMR with Conventional Methods
1. Weak Implementation of National Action Plans: Only a small percentage of the more than 170 nations that have created AMR action plans have operationalized them with specialized financing and monitoring mechanisms. This leads to a gap between policy and practice, especially in low- and middle-income nations.
2. Restrictions in the Management of Antimicrobials: Lack of qualified staff, insufficient microbiological assistance, and shoddy governance frameworks are some of the common obstacles that antimicrobial stewardship initiatives must overcome. Due to the lack of quick diagnosis, broad-spectrum antibiotics are still empirically used in many hospitals.
3. Diagnostic Barriers: Rapid diagnostic methods are still few, and traditional culture-based susceptibility testing is sluggish. Resistance selection is accelerated by this diagnostic latency, which frequently forces physicians to use broad-spectrum empirical treatment.
4. Surveillance Gaps: Despite the growth of programs like the Global Antimicrobial Resistance and Use Surveillance System (GLASS), data quality and surveillance coverage are still uneven. The inability of many nations to track resistance in important diseases compromises prompt policy responses.
5. Limited Innovation in Drug Development: Only a few new types of antibiotics are now in advanced clinical development, making the pipeline still rather thin. Under the present traditional paradigm, pharmaceutical innovation is discouraged by market failure due to low return on investment.

The physical, social, or experimental context in which research is carried out is referred to as the research setting. This context must be accurately described in a study publication because it might significantlyaffect the outcomes and the interpretation. For instance, in a study that depicts chimpanzee’s social behaviour, the authors may need to give the description of the research environment, includingwherethe chimpanzees were seen whether they are in the wild or captivity, and whether they belonged to the same place,thesametime,the samestudyterm,thetimeof yearandweather, theaccessibility of resources like food, drink, and shelter, the presence of dangers from the environment and so forth. The environment in which studies are conducted, or the research setting, has asignificant impact on how the results are interpreted. Doing a study in an experimental setting, for instance in the lab, you might be able to control variables in ways that you can’t control in the field, and it could be argued that the results don’t accuratelyrepresent reality. It is frequently crucial to undertake complementary research in a variety of research context to strengthen the generalizability of the results.
4.1. Area of the study
The study was conducted at Bilkumari village of Bilkumari gram panchayat in Nakashipara block in Nadia district in West Bengal.
4.2. Profile of West Bengal
On August 15,1947, as a result of the division of the undivided, West Bengal was established as one of the constituent state or the Indian union among the 29 states in India. The location of the West Bengal is in India’s north- eastern region between 21°37'-27°10' north latitude and 85°51'-89°53'east longitude. It is located in the country’s eastern part and fourth most populous state. It has theseventh-highest population density among sub-national entities worldwide. The sixth largest contributor to country’s GDP is WB. It is surrounded bythe countries of Bhutan, Nepal, Bangladesh and the states of Bihar, Jharkhand, Orissa, Sikkim, Assam with an area of 34,267 sqm with Kolkata as its capital. The sub and Himalayan region in the north, and the Gangetic Plain in the south comprise the two principal natural areas that comprise West Bengal. Despite the factthat West Bengal is oneofthesmallerstates, it isoneof India’slargest states in terms of population with 91million people. Agriculture is the main economicsector, the state’s population is primarily agricultural workers andfarmers. Rice is regarded as the primary food crop. Maize, legumes, oilseeds, wheat, barley, and potatoes are some of the major food crops. Nearly 66% of India’s jute needs are met by the state. Tea is the key cash crop. Darjeeling’s tea plantations are one of its main draws. Being widely known for its artistic achievements, particularly its filmmaking.

Introduction

Marketing and promotion are important for any organization that provides services to consumers. Marketing and promotion allow an organization to inform, remind, or persuade the consumers by sharing information about goods or services, community involvement, or societal impact. Simply stated, these efforts encompass anything libraries do to let the community know who they are, what they do, and what they offer. The goal of marketing is to keep the product in the minds of the customer: in the case of libraries it is to keep the customer aware of the library, to provide them with knowledge about the library’s physical features, resources, services, programs, and events, and to let them know about the benefits libraries offer. Marketing and promotion benefit the library by increasing usage, educating users, and increasing or at least maintaining a positive perception of the library.

Basella (Basella alba syn Basella rubra) is also known as Poi, Ceylon spinach, Malabar spinach, Indian spinach or vine spinach. It is a popular leaf vegetable grown in almost all parts of India and widely grown in North-East and South India. Besides India, it is widely cultivated in tropical Asia and Africa. It is a climbing perennial plant, but is sometimes cultivated as an annual vegetable. The plant is succulent with tender leaves. It is a fast growing, productive leaf vegetable for home gardens and market growers. 

Composition
Young shoots and leaves of Basella are a rich source of calcium, iron, and Vitamins A and C.

Uses
Fresh tender leaves and stems are consumed as leaf vegetable after cooking. It is preferable to cook the leaves in soups and stews as half of soluble solids may be lost by boiling in water. Red cultivars contain a colouring matter in leaves, stems and ripe fruits reported as a dye for colouring food. Because of its mucilaginous nature of leaves and stems, it is used as poultice. Juice of leaves is prescribed against constipation, especially for children and pregnant women (Burkill, 1935).

A large number of insect pests are associated with stored grains which are directly related to geographical and climatic conditions. There are different estimates on post harvest losses in food. During storage both quantitative and qualitative losses occur due to insects, rodents, and microorganisms. Almost all the insect species may destroy 10.0 - 15.0 % of grain and contaminate with undesirable odour. These pests also helps in transportation of fungi. Some insect pests initiate damage at the ripening stage of crops and continue during storage. Major sources of infestations are old gunny bags, storage structure and old containers (Pruthi and Singh, 1950). The spread and distribution of stored product pests are facilitated by movement of grains from one area to another and by flight of insect pests as some of the adult insects are strong fliers. The cracks and crevices are probable sites for cross infestation. Nearly one thousand species of insects have been associated with stored products in different part of the world. Majority of insect pests belong to the orders Coleoptera and Lepidoptera (Khare, 1994).

Much has been talked about the mighty river systems and their migratory histories, since Purana and Vedic times. In Mahabharata the places where the Lord Krishna is said to have played with Gopis in the banks of River Yamuna are now forming flat lands many kilometers away from the present day Yamuna. In the same way, there is a mention in ancient literature about the ‘Indo-Brahm’ river which was originated from the Himalayas and flown through Brahmaputra valley, Indo-Gangetic plains, Rajasthan desert and met the Arabian Sea in Rann of Kutch. Such a mighty river is said to have fragmented into Brahmaputra, Ganges and the Indus rivers due to Tectonic activity in Himalayan regions. Similarly there are many evidences in the Tamil literature. For example in ‘Kalingathuparani’ it is mentioned that the river ‘Palar’ was flowing north of Kanchipuram but the same river is now flowing south of it.

All these facts show that the rivers have the tendency to frequently change their courses. The advent of modern Remote Sensing Technology has opened up new vistas in studying such migratory rhythms of the rivers, as such old and buried rivers exhibit spectacular ribbon like, linear, curvilinear and contorted features with typical darker tone in black and white images and reddish tone in false color composites (FCC) and other color coded images.

Rapid urbanization and industrialization has led to continuous deterioration of air quality, which is a major environmental problems in many urban areas in both developed and developing countries. Air pollution is characterized by high concentration of suspended particulate matter, oxides of sulphur and nitrogen resulting primarily from increased use of vehicles. Air pollution effects are not limited to the short term nor to the plant damaged or killed. Rather, air pollution has long term effects that affect plants including fruit trees. Horticultural crops are injured when exposed to higher of abnormal levels of various air pollutants. The injury symptoms range from visible marks on foliage, reduced growth and yield to premature death of the plant. The development and severity of injury depends not only on the concentration of the particular pollutant, but also on a number of other supporting factors. These include the duration of exposure to the pollutant, the plant species and development stage as well as conducive environmental factors.

There are several species in this cosmopolitan family that are of importance chiefly as pests of stored foods, flour, grain, seeds and bulbs, feeding on these products or the fungi that develop on them. These mites are mostly very minute, almost colourless, with the body bearing a few long setae, and with the legs terminating in one claw and usually a sucker. When very abundant the mites and their cast skins form a buff-colored dust and give rise to a characteristic odour. The living mites move slowly away from a source of light. An interesting characteristic of these mites is a nymphal resting stage (hypopus) during which they take no food but attach themselves to other mites, insects and humans by means of suckers and are thereby transported to other suitable places for development, where they drop off, moult, feed, and develop into adult stage. The hypopus may be resistant to fumigants. However, the cheese mites, Tyrophagus casei do not have a hypopial stage. Prolonged storage of products subject to infestation without cleaning of pantries and shelves where such materials are placed. These mites can subsist on organic debris in cracks, crevices and corners and are readily spread to other areas.

MOMENTS

The term moment in mechanics refers to the measure of a force with reference to its tendency to produce rotation. The strength of this tendency is depen- dent upon the amount of the force and the distance from the origin at which the force is applied. If on both the sides of the origin the force are equal than there will be a balance, at a balanced position the positive product equals the negative product.

Moment is used in Statistics in a quite analogous sense. The class frequencies are looked upon as the forces and the deviations of the different values from the mean are taken as the distances. In other words, moment is the mean of the first, second, third, fourth, etc. powers of deviations of the different values from the arithmetic mean. The first moment about the mean is always zero and second moment about the mean is variance.

If the moment calculated from arithmetic mean are called central moments and denoted by μ with a subscript which indicate the order of the moment. Moments are the mean values of powers of the deviations in any frequency distribution taken about three points

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.

India has a very wealthy tradition of herbal medicines for the treatment of many health discomforts.The tradional healing practicese are common and popular among all the tribes and communities.It is evident that many communities have so much belief in their ethnobotanical knowledge that they often prefer a traditional medicineal practicener over any certified medical personality. Among all the plant species which have been already reported by many researchers for their ethno medicinal properties are getting very rare in their original habitat.These plants are obviously of great medicinal importance and immediate need of conservation.Some medicinal plants which are exclusively found in forest are getting lost due to habitat fragmentation and enormous deforestation.
