Introduction
Temperature regulation is a critical physiological process that allows animals and birds to maintain homeostasis in varying environmental conditions. Thermoregulation involves a complex interplay of behavioral, physiological, and biochemical mechanisms that ensure the body temperature of these animals remains within a narrow, optimal range. This process is vital for maintaining metabolic functions, health, and productivity, particularly in agricultural settings where animals are often exposed to temperature extremes.In farm animals such as cattle, sheep, and pigs, thermoregulation is primarily managed through a combination of heat production, heat dissipation, and behavioral adaptations. Endothermic animals generate heat internally through metabolic processes, particularly in the muscles and liver. This heat is distributed throughout the body via the circulatory system. When ambient temperatures rise, farm animals activate various cooling mechanisms to prevent hyperthermia. These mechanisms include increased respiratory rates (panting), sweating (in species like cattle and horses), and vasodilation, where blood vessels near the skin surface expand to dissipate heat. Conversely, in cold environments, animals reduce heat loss by vasoconstriction, piloerection (raising of hair or fur), and seeking shelter or huddling together. Behavioral adaptations, such as seeking shade or water, also play a crucial role in temperature regulation.In poultry, thermoregulation is equally important but is managed differently due to their unique physiology. Birds lack sweat glands and have a higher metabolic rate compared to mammals, which means they rely more heavily on respiratory evaporative cooling and behavioral adaptations. Poultry regulate their body temperature by panting, which increases evaporative heat loss from the respiratory tract. Additionally, birds adjust their posture, such as spreading their wings or ruffling feathers, to enhance heat dissipation. During cold stress, poultry increase their metabolic rate, fluff their feathers to trap air for insulation, and reduce blood flow to peripheral areas to conserve heat. The thermal comfort zone, or thermoneutral zone, is narrower in poultry compared to larger mammals, making them more susceptible to temperature extremes.The ability of farm animals and poultry to regulate their body temperature is influenced by several factors, including age, breed, body condition, and acclimatization to the environment. Younger animals and certain breeds are more vulnerable to temperature stress due to their less developed thermoregulatory mechanisms or specific genetic traits. For instance, breeds with higher muscle mass or thicker coats may be more prone to heat stress, while those with lower body fat reserves may struggle in cold conditions. Acclimatization, or the gradual adaptation to a new thermal environment, plays a key role in enhancing the thermoregulatory capacity of these animals.

Abstract

Landslides have become a recurring phenomenon in most of the mountainous regions of the world. In Indian peninsular, the landslides which were mostly confined to the tectonically active Himalayan Mountains once, have started spreading over to the other mountain belts of the Peninsula. The Tirumala – Tirupati hills, which is drawing millions of pilgrims from all over the world is facing landslides especially along the newly built southern uphill ghat road. The geology of the area, studied using Geomatics tools like Remote Sensing, SRTM based Digital Elevation Models, GPS Survey, etc., showed that Tirumala hills is under the grip of upward tectonic movements as evidenced from the N-S and E-W oriented Pleistocene faults, intensely dissected Plateau top Cuddapah Quartzites, retreating escarpments, exhaustive debris slope, extensive valley fills along the slopes, colluvial fills in lower slopes, palaeo debris flows along the southern and western obsequent slopes of the Tirumala hills etc. All these indicate the inherent landslide vulnerability of the slopes. The E-W trending dykes which are piercing the slopes and protruding as ridges add further landslide vulnerability to such fragile slopes. So, the new ghat road laid along such southern slope is obviously facing landslides. However, the detailed Geomatics based studies show that the dykes, valley fills and steep slopes are particularly more vulnerable to landslides. Though remedial measures have been broadly evolved, abandoning the southern uphill new ghat road and widening the older northern downhill ghat road seems to be the better and long term feasible alternative to prevent Landslides in the area.

1. INTRODUCTION

Until the 1990s, the phrase Corporate Governance (CG) was relatively unknown but since then it has gained a huge importance when the corporate sector was surrounded with problems of unethical practicesand flagrant violations of rules and regulations in a number of countries. CG has received increased attention as multiple cases of risk of corporate failures both for public and private sectors. Multiple corporate failures worldwide, such as those of Maxwell, Enron, Global crossing, and Sunbeam forced the regulatory authorities to set up codes and standards on CG.The Indian market has also faced a number of scams since early nineties.Harshad Mehta Stock Scam in 1992 is one of the corporate frauds in the country which finally resulted in setting up of Kumar Mangalam Birla Committee in 1999. Based on their recommendations in 2000, Clause 49 on CG was inserted in the listing agreement of every stock exchange in India. The purpose was to promote and raise standards of CG of listed companies. CG has now become most common phrase in the business world of 21^st century. It is important for financial health of the corporations and relationshipwith the public at large; may it be an individual or community especially after the collapse of Satyam Software Services Ltd. in 2008.It has been made mandatory for the Indian companies to comply with CG norms, to give reports and disclosures as per the listing agreement and various provisions of the Companies Act in their annual reports. The importance ofCG in the 21^st century keeps on increasing as the economy is growing.

Introduction

The term "nano" is used to define one that has a size in the nanometer range. Nanotechnology is an interdisciplinary field of medicine, chemistry, physics, and biology that has emerged during the past few decades as a potential area of study. The goal of this interdisciplinary technology is to transform molecules into entities, then do the opposite. Nanobiotechnology is the term for the fusion of nanotechnology with biotechnology. In nanobiotechnology nanoscale principles and techniques are used to explore biosystems and generate novel biomaterials. Biosensing, cell labelling, and molecular imaging can all gain benefit from nanostructure materials in life science, health and biomedicine.

Introduction

A complete neurological examination is warranted whenever an equine patient displays signs consistent with neurological disorder or to establish that the horse is neurologically normal (e.g., pre-purchase examination). Neurological examination of equine patient is challenging due to their large size, which prevents veterinarian from using many of the tests used for small animals. The key to a successful neurologic examination is to do the examination in a consistent and organized fashion. It is important to develop a routine, then do it the same way each time. This approach ensures that some parts of the examination are not forgotten and it also increases the consistency of the exam as you examine more number of equine patients. A standardized examination form is a valuable aid in this and can be concise. The goals of the neurologic examination are to determine whether disease of the nervous system exists, to localize the lesion to a particular area of the nervous system, and to describe and record the responses as a baseline for future evaluations. In this paper, a complete neurological examination is described with special emphasis on field conditions.

A tumor is said to be an abnormal growth of cells to form a lump or mass of transformed cells. This growth occurs due to loss of regulatory control of cell division. The majority of cells and organs have a balance between cell renewal and cell death. A cell has a particular life span;when it dies a new cell is generated. In normal condition, this system is regulated through cell cycle and cell division but at the time of any abnormality this growth mechanism is totally disturbed and failed. These cells give rise to clone of the cells and eventually produce tumor.

Abstract

Northeastern part of the Indian subcontinent is seismically an active region, and is further prone to excessive rainfall and frequent landslides, which cause disruption of the road networks during the monsoonic months every year. The region owns a typical morphotectonic setup where many active thrusts and faults have carved out the landforms and physiography of the major part of the region. The creeping phenomenon of the N-S trending prominent strike-slip fault, namely the Churachandpur - Mao Fault (CMF), is one of the triggering factors for the frequent landslides and low magnitude earthquakes. The life line of Manipur, the national high way NH39, traverses along and in close proximity to this fault in Manipur, and hence the life is paralysed in the area during the monsoonic months. From the GPS campaign mode studies on the western and eastern sides of the CMF, it is observed that there is a change in the crustal velocities from 16 - 22 mm/yr in the east to 33 - 42 mm/yr in the west. Micro-deformations are also observed in the form of displacements respectively with the vertical, N-S and E-W components of–0.111 mm/yr (downward), 0.03 mm/yr (northward) and –0.011 mm/yr (westward). The net displacement is 0.126 mm/yr with an azimuth of N 85° and dipping of 13° towards west. Neotectonic movements along the CMF, as per the GPS measurements, suggest an aseismic nature of the fault with dextral component. Fault plane solutions of the earthquakes show northerly directed principal P-axis indicating the extension (T-axis) along east-west. The resultant creeping of micro-deformation towards the western slopes of the terrain is aligned with the principal T-axis. The creeping triggers the micro seismicity as well as the landslides along the CMF.

ABSTRACT

The present paper identifies new emerging areas of usage of computer application in Horticulture research and development.

INTRODUCTION

The horticultural sector is facing the challenges of dwindling land resources, increasing biotic and abiotic stresses, indications of factor productivity decline, threatened loss of bio-diversity, new IPR regime etc, (Adiguru and Mruthyunaja, 2004). Further, Indian agriculture has come under significant adjustment pressure from market liberalization and globalization. Farmers need reliable and timely information about best practices of production, processing, marketing, input and output prices, financial markets and risk-covering institutions. Existing public extension system has become outdated and ineffective in spite of the fact that it has been a catalyst in successfully heralding the Green Revolution in the country. This is partly due to an inadequate use of new means of information dissemination (Adhiguru et al., 2003). The public extension system follows a top-down approach and has become less interactive, more time-consuming and costly and fails to meet the expectations of those involved in the agricultural production and other involved in the value chain. Therefore, a new extension system re-oriented to meet the information needs of the farmers should be put in place across the country by using ICT.

Introduction

The “plant disease triangle” is a fundamental concept in plant pathology that illustrates the interaction between three essential components necessary for the development of a plant disease. Firstly, the host plant which refers to the plant species or cultivar that is susceptible to the pathogen. Host plants provide the necessary environment and resources for the pathogen to establish, grow, and reproduce. Secondly, the pathogen which is any organism (such as fungi, bacteria, viruses, nematodes, or other microorganisms) that can cause disease in plants. Pathogens can infect host plants through various means, including direct contact, airborne spores, soil-borne organisms, or vectors such as insects. And thirdly, the environment which encompasses all external factors that influence the interaction between the host plant and the pathogen. This includes abiotic factors such as temperature, humidity, soil moisture, light, and nutrient availability, as well as biotic factors such as the presence of other organisms (competitors, predators, symbionts) that may affect disease development.

The plant disease triangle illustrates that the occurrence of a disease requires the presence and interaction of all three components: a susceptible host, a virulent pathogen, and a conducive environment. If any of these components is missing or unfavourable, disease development may be inhibited or prevented. Any change in ecosystem can affect plant diseases, because plant disease is the result of interaction between a susceptible host, virulent pathogen and favourable environment. If any of the three factors are altered, the progress of any one disease can change. Although interactions among the three factors must be matched, weather is an important variable due to its dynamic behaviour.

Introduction

Biotechnology, in the recent years, has created unprecedented opportunities not only for the manipulation of biological systems for the benefit of mankind, but also to understand studies for better understanding of the fundamental life processes. Consequently, it has become the fastest and most rapidly growing technology in the world. As per US National Science Foundation, “Biotechnology is defined as any technique that uses living organisms or parts of organisms to make or modify products, to improve plants, amend animals or to develop microorganisms for specific uses”. Biotechnology offers new strategies that can be used to develop transgenic crop plants with improved growth, yield and quality and tolerance to biotic and abiotic stresses. By transgenic crop, we mean any plant containing a gene(s) which have been artificially inserted instead of the plant acquiring them through pollination. A plant in which a foreign gene has been transferred through genetic engineering is called transgenic plant and the gene so transferred is called transgenic. The inserted gene sequence known as transgene may come from another unrelated plant or from completely different species. Plants containing transgene are often called genetically modified or GM crops. Transgenic technologies have opened up many exciting possibilities to improve products with added value having application in food, agriculture, animal husbandry, environment, medicine and industry. It also offers uncommon opportunities for improvement in genetic potential of plants and animals by introduction or removal of gene(s) that regulate a specific trait.

The well-being of a person depends on his immune system. Any deficiency in any component of immune system may lead to defects in the normal functioning of his body and makes him more susceptible to diseases. The immunodeficiency may be either in specific components (B cells or T cells) or nonspecific component (phagocytes and complement) of the immune system.

An understanding of intellectual property rights for plant breeders has become increasingly important over the last few decades. It is also a confusing topic to many in the industry. Confusion is understandable when we are presented with various types of protection, many acronyms, terms used interchangeably and incorrectly, regulations that vary internationally and a lack of understanding or consistent interpretations of laws that govern these rights.

Plants are unique from other marketed products due to their complex nomenclature, ease of propagation and the many levels of distribution and promotion involved in their marketing. The protection is required for a plant cultivar needs to be considered in relation to all of these factors in order to be correctly implemented and maintained. Breeding and commercialization of new ornamental plant varieties is an economically important activity both for the industry and the well being of our society. Breeding or developing a new variety requires a long time. In horticultural crops, it takes 3-10 years from initial crossing of parent cultivars to develop a commercial variety. It is important to encourage development of new variety by providing incentives such as Plant Breeders’ Rights (PBR) over exclusive production and marketing of seed of an improved variety. When the new cultivar is introduced and commercialized, plant breeders finally begin to get paid for their years of hard work in the form of royalties. Legal protection for new plant varieties provides the means by which companies, institutions, and independent plant breeders can receive a return on their investments of time and money as well as justify their involvement in research and new plant development. In addition, legal protection enables plant breeders to be recognized for their craft and skill and encourages plant breeding as a profession. Plant variety protection provides an incentive for continued breeding and to ensure the availability of new varieties that meet future demands and keep the industry thriving.

Organic Fertilizers and Manures

Farmers have been using organic waste as fertilizers for a very long time. As previously mentioned, the application of O.M. to a soil can have number of beneficial effects on soil structure, C.E.C. and microbial activity. However, organic manures mainly originate from the waste products of animal and plant production and although rich in carbon compounds, they are usually relatively poor in available plant nutrients.

The nutrient content of organic manures varies widely depending on their source and moisture content. Farm yard manure (F.Y.M.) is one of the most common organic fertilizers used. Others are concentrated animal manures, and crop residues such as straw.

Introduction The world recently celebrated the birth of its eighth billionth baby, a major milestone in the development of the human race and the doubling of our numbers in 47 years. This tremendous growth has been driven by ambitious advances in technology and health care, soaring achievements of global prosperity and a longer life expectancy that has come to a staggering 72 years. However, the glory of these achievements is marred by how we are failing the lion’s share of the global population in meeting their basic requirements. Almost one in seven people on our planet do not have enough to eat. Food and nutritional insecurity are detrimental to human development and are a major brake on overall socio-economic development which downplays any major accomplishments we have made since not having enough to eat is an international security issue. Adequate food production, easy access and the capacity to buy food, relevance concerning nutrition and stability of these elements are all necessary for sustainable food security (Helland and Sorbo, 2014).

Introduction
Toxic inorganic and organic compounds are continuously contaminating our environment, endangering both human health and the planet’s ecosystems. This is a major worldwide problem. Because they persist in the environment, these pollutants which are caused by industrial processes, agricultural practices, urbanization, and over use of natural resources are very hard to control. While inorganic contaminants, including heavy metals, are difficult to break down naturally and need more complex remediation techniques, organic molecules may frequently be broken down into less dangerous components. Among these methods, bioremediation has become a viable, environmentally beneficial option that uses the inherent powers of fungus, bacteria, and plants to purify
and repair polluted soils and streams.
Phytoremediation, a specific form of bioremediation, harnesses the power of green plants to absorb, accumulate, degrade, or stabilize these harmful substances (Wang et al., 2021). This process not only mitigates pollution but also revitalizes ecosystems by improving soil structure, increasing biodiversity, and supporting sustainable land use. Phytoremediation provides a low-cost
and less intrusive substitute for conventional cleanup techniques, which frequently entail high-energy procedures, chemical treatments, or considerable excavation, as the globe struggles with the growing danger of environmental deterioration. Rapid industrialisation, urban waste, and natural activities can introduce large quantities of highly toxic organic pollutants, including
petroleum hydrocarbons, nitro and halogenated aromatic compounds, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), dibenzofurans and dibenzop-dioxins (PCDD/Fs), solvents, explosives, and pesticides, into both aquatic and soil ecosystems (Tanwir et al., 2021). One of the major challenges to reducing water pollution is the presence of heavy metals including cadmium (Cd), lead (Pb), and chromium (Cr) in industrial and agricultural runoff. Associated with other pollutants, these metals disrupt aquatic ecosystems at the species and community levels, which has an array of negative impacts on animal and human health. The World Health Organization (WHO) has emphasized how important it is to keep an eye on these chemicals in drinking water because of their link to serious health concerns including cancer, respiratory disorders, and cardiovascular illnesses.

CALIBRATION OF SEED DRILL
Calibration of a seed drill refers to the process of testing the seed drill to ensure it delivers the correct seed rate. Before using the seed drill in the field, calibration is essential to achieve the desired seed rate. This procedure is done to ensure that the machine delivers the predetermined seed rate accurately. The following steps are followed for the calibration of a seed drill.
Procedure for Calibration of a Seed Drill
• Determine the nominal width (W) of seed drill .
W = M x S,
Where, M = Number of furrow openers
S = Spacing between the openers, m
• Find the length of the strip (L) having nominal width (W) necessary to cover 1/25 ha (1 /25 x 10000 m2).
L = 400/W meter
• Determine the number of revolutions (N) of the ground wheel of the seed drill
required to cover the length of the strip (L).
L = P x D x N = 400/W
N = 400/P x D x W revolutions per minute
• Jack the seed drill so that the ground wheels turn freely. Make a mark on the drive wheel and a corresponding mark at a convenient place on the body of the drill to help in counting the revolutions of the ground wheel.
• Fill the selected seed in the seed hopper. Place a container under each boot for collecting the seeds dropped from the hopper.

One of the characteristics of the immune system is to recognize and discriminate self from the non-self antigens.  But, sometimes, there is a failure to discriminate between self and non-self antigens in the body and an autoimmune response occurs. Body starts producing antibodies against its own cells/antigens. These antibodies are called autoantibodies and this state is called autoimmunity.

1. INTRODUCTION

Science and Technology are vital for developing low-input and high-output agriculture and pharmaceutical. India needs frugal use of natural resources and diversification of agricultural activities. Transgenic technologies are highly misunderstood. Genetically modified crops are a result of them. In fact genetic modification of crops for human use is going on since their domestication. By introduction of Bt cotton in 2002, yields have doubled. American bollworm can no longer threaten Indian cotton crops. Insects can develop resistance to Bt gene or some virus attacking the crop needs more research. RNA-mediated gene suppression may aid the development of patent strategies that will support the next generation of genetically modified crops and enhance scope of patenting. Many fancy Organic farming, which will need 40 percent more agricultural land for present number of people on earth although it is ever increasing. Biotechnology has revolutionized agriculture, healthcare, industrial processing, environmental sustainability and is also a revenue generator. India is poised for a tremendous growth in BT sector. NanoBT has now entered into furthering the useful research on faster pace. It has scientific and technical pool of human resources, rich biodiversity, large agricultural and market base for new BT products and world recognition as a producer of low cost, high quality bulk drugs and formulations. Issues surrounding Intellectual Property Rights and BT inventions are varied but interrelated. Basic research has to be transferred to applied field and the resultant is to be commercialized. In some countries, plant varieties are protected by sui generis system. Post genome research has added fuel to the fire; new innovative fields, like ‘Bioinformatics’ with plenty of biology information and new processing methods have emerged. BT uses four tools of IPR, viz. Patents, Trademarks, Trade secrets and Copyright. At present, its contribution to the World’s patenting activity is less than three percent. As such there is a necessity to amend the IP laws to give better protection to R&D, and better enforcement of IP, technology transfer and licensing arrangements. Biotech industry in India is flourishing more in pharmaceuticals, particularly in healthcare. There is an urgent need for harmonization of administration and centralization of the patenting process in accordance with WIPO diktats.
