Introduction

In poultry, the intestine is home to trillions of microorganisms, with bacterial concentrations reaching up to 10¹² bacteria per gram of digesta. In a healthy digestive system, this microbial community is highly diverse and metabolically active, supporting crucial functions in digestion, immune defense, and overall health. The gastrointestinal tract (GIT) of a newly hatched chick begins as a sterile environment but quickly develops a complex microbiota as the bird matures. The composition of gut microbiota is highly variable, shaped by environmental factors, diet, the genetic makeup of the host, and other influences. This dynamic microbiome plays a pivotal role in nutrient absorption, disease resistance, and growth efficiency, making it a central focus in poultry health management and productivity enhancement.The health and productivity of poultry are fundamentally influenced by the gut microbiome, which shapes digestion, immunity, and growth potential. Microbial diversity variesacross several poultry species, including broilers raised intensively, native chickens in free-range conditions, and unique species such as Guinea fowl, Kadaknath, and red jungle fowl. Using advanced metagenomicsanalysis of microbial diversity, structure, and function, highlighting the implications of microbiota composition on poultry health and productivity possible. The gut microbiota is increasingly recognized as a major determinant of health and productivity in poultry. It not only influences nutrient absorption and metabolism but also plays a critical role in immune response and pathogen resistance. Intensive farming practices have altered gut microbial ecosystems in commercial broilers, often reducing diversity compared to native breeds and heritage species raised in field conditions.

Description and Distribution
Under the Prevention of Food Adulteration Act (PFA) of the Government of India (amended upto 31 March 1996) both Caraway (Carum carvi Linn.) and Black caraway (Carum bulbocastanum W.Koch) have been described in Hindi (Indian language), as “Siah zira” or “Kala zir””. These two species have similar cultural requirements and are thus covered under one head
Caraway
About 2000 years ago, Roman soldiers dispersed Caraway seed from it’s home in Asia Minor to most of known countries of the world. North Europeans and central Europeans, especially the British and Germans, respectively, have been using it since centuries. In India, also, it is being used since long. Caraway or Caraway seed of commerce is the fruit of a biennial herb. It is a native of North and Central Europe, and is extensively cultivated in Holland, Poland, Russia, Bulgaria, Denmark, Syria, Morocco and to a small extent in England. It has been introduced into the USA, where it is grown as a garden crop. It (Black Caraway or Kala zira) grows wild in India in the north Himalayan regions. It is also cultivated in the Indian plains. It is also cultivated as a cold season crop in the hills of Kashmir and Kumaon at an altitude of 2740 – 3660 meter above mean sea level, as a summer crop. The Caraway plant usually has a fleshy root and a slender branched stem, that attains a height of 0.5-0.6 meter. The compound pinnate leaves are divided into very narrow segments, the small white flowers are borne in fleet, compound umbels; the fruit, when ripe, splits into narrow, elongated carpels. A fruit is 4-6.5mm long and curved, pointed at the ends, and with 5 longitudinal ridges

Introduction
Antimicrobial resistance (AMR) has emerged as a critical global health threat, diminishing the effectiveness of antibiotics against bacterial infections. Conventional strategies to counter AMR—including antibiotic stewardship programs and the development of new drugs—are often slow, expensive, and labor intensive. However, artificial intelligence (AI) and machine learning (ML) present ground breaking alternatives to address this challenge. By leveraging advanced computational techniques, AI can significantly speed up the discovery of novel antibiotics, enabling researchers to identify promising drug candidates more efficiently than traditional methods. Additionally, ML algorithms enhance treatment optimization by analyzing patient data to recommend personalized antibiotic regimens, reducing misuse and resistance risks. AI also strengthens surveillance systems by processing vast datasets— such as genomic sequences and electronic health records—to detect emerging resistance patterns in real time. These capabilities allow for proactive interventions, helping healthcare providers and policymakers stay ahead of AMR outbreaks. Together, AI and ML offer a transformative approach to mitigating AMR, combining speed, precision, and scalability to combat one of the most pressing medical challenges of our time.
AI in Antibiotic Discovery
One of the most promising applications of AI in AMR mitigation is in antibiotic discovery. Traditional drug development is costly and time-consuming, often taking over a decade [1]. Machine learning models can analyse vast datasets of chemical compounds to predict their antibacterial properties. For example, researchers at MIT used deep learning to identify halicin, a novel antibiotic effective against drug-resistant bacteria. AI-driven platforms can also repurpose existing drugs, reducing the time needed for clinical trials [2].

Predictive Analytics for Resistance Patterns AI-powered predictive analytics enables early detection of antimicrobial resistance (AMR) patterns by processing clinical, genomic, and epidemiological data. Machine learning models analyse electronic health records (EHRs) [3] and bacterial genome sequences to identify emerging resistance threats in real time. These predictive insights allow hospitals to take proactive measures— such as optimizing antibiotic prescriptions—before resistant strains spread. Beyond clinical settings [4], AI models assist public health agencies in forecasting outbreaks and strategically deploying resources. By integrating large-scale datasets, these systems enhance surveillance, enabling faster, datadriven decisions to curb AMR progression. This approach not only improves patient outcomes but also supports global efforts in combating antibiotic resistance through smarter, pre-emptive interventions [5].

In an orchard all the fruit trees do not bear equally or regularly and sometimes fail to flower and fruit under similar conditions where another fruit tree bears heavily. This failure to set fruits may be attributed to unfruitfulness. To understand the problem of unfruitfulness in orchards a familiarity with following terms is necessary.

1.    Fruit setting: It refers to initial growth of ovary and its associated parts after blossoming and taking it to maturity.

2.    Fruitfulness: It is the state of plant when it is not only capable of flowering and fruit setting but also takes these fruits to maturity and inability to do so is unfruitfulness or barrenness.

3.    Infertility: Ability of a plant not only to produce fruits but develop viable seeds and the inability to do so is referred as sterility or infertility. All fertile plants are fruitful but all fruitful plants are not fertile (Seedless fruits).

4.    Self fruitfulness: Ability of a plant to mature fruits after self pollination.

ABSTRACT

The carbonatites are genetically and geochemically distinct and contain several rare earth minerals that are unknown or are very rare in other types of rocks. A useful review of the REE’s in carbonatites is given by Cullers and Graf (1984), who point out that carbonatite contains the highest concentration of REE’s and highest LREE: HREE (La:Lu) ratio of any igneous rock. High REE abundances are considered as the diagnostic character of carbonatites to discriminate them against recrystallized limestone. Rare earth mineralization in carbonatities can be classified into three categories. The first is primary magmatic crystallization (bastnaesite). The second is hydrothermal mineralization and the third is supergene mineralization produced by weathering of carbonatitie bodies. The only economic Nb mineral in carbonatite is pyrochlore. Apatite deposits constitute the largest bulk mining in carbonatites and have higher phosphate content than marine phosphorites. Pyrochlore, cubic fergusonite, eschynite, Fe-Nb rutile, monazite apatite, bastnaesite and allanite are the rare earth minerals that are enriched in Tamil Nadu carbonatites. Such enrichment of above rare earths is typical of undersaturated alkaline complexes. The lanthanides are seen associated with these minerals, mainly the light lanthanides are predominant than heavier ones. Thus the carbonatite complexes provide the locus for several metal deposits that are presently of strategic importance, containing elements, which are otherwise largely dispersed in earth crust.

Introduction

Status of Tuberculosis : Tuberculosis is a complex and multispecies disease since the origin of human civilization. Evidence of tuberculosis (TB) exists in 3000 years old Egyptian mummies and about 17,000 year old fossilized bison (Fareed et al., 2024). Now, every year, 10 million people fall ill with tuberculosis. Out of 10 million people currently with new active TB, 1,40,000 (range, 69,800–235,000) are estimated to be new cases of zTB (1.4%) of which an approximately 11,400 (8.1%, range 4,470-21,600) died (WHO, 2020).Despite being a preventable and curable disease, 1.5 million people die from TB each year – making it the world’s top infectious killer (WHO, 2023). Disease is still in an increasing scenario as evident that in 2018, an estimated 10 million people fell ill with TB and 1.5 million died of the disease whereas in 2021 there were an estimated 10.6 million new cases of TB and 1.6 million TB deaths (Ayalew et al., 2023). COVID-19 has further increased the projection of TB and increased the expected case number. As it is predicted that between 2020-2050, 31.8 million will have died of TB, More than half million cases of TB annually are classified as drug resistant, as a result, TB is becoming more difficult to diagnose and treat.

Seed rearing for exotic carps and catfish involves careful management of spawn (fertilized eggs) and larvae in nursery systems before they are transferred to grow-out ponds. This phase is essential to ensure the survival, health, and growth potential of the fish stock. Key factors in this process include maintaining optimal water quality, temperature, and the provision of appropriate food sources—either natural or supplemented. Proper stocking densities and regular monitoring play a vital role in ensuring success. The seed rearing of exotic carps such as Common Carp (Cyprinus carpio), Silver Carp (Hypophthalmichthys molitrix), and Grass Carp (Ctenopharyngodon idella), along with catfish like Magur (Clarias batrachus) and Pangasius (Pangasianodon hypophthalmus), is significant in enhancing aquaculture productivity in India. These species are favored due to their fast growth, adaptability to diverse environments, and strong commercial demand. Good seed rearing practices ensure a steady supply of healthy and vigorous fry and fingerlings for stocking in grow-out systems. These species are generally bred in hatcheries using induced breeding techniques. Once the hatchlings emerge, they progress through several developmental stages—from spawn to fry to fingerlings. This seed rearing period typically lasts 20 to 40 days, depending on the species and environmental conditions. Nursery systems such as earthen ponds, hapa enclosures, tanks, and cages are commonly used. Each system is managed carefully to ensure optimal conditions regarding temperature, dissolved oxygen levels, pH, and feeding.

Agribusiness: A Dynamic Concept
Agribusiness, an ever-evolving concept since its introduction in the 1950s, encompasses a broad spectrum of business and management activities linked to agriculture. Downey and Erickson defined agribusiness as encompassing all activities undertaken by firms that supply inputs to the farming sector, produce agricultural products, and process, transport, finance, or market these products. Chait extended the definition to include agriculturally related businesses such as warehouses, wholesalers, processors, and retailers.
In developed countries, agribusiness is broadly defined as the total output from farm production and processing at both pre- and post-farm gate stages. In contrast, in developing nations like India, agribusiness is categorized into four distinct sub-sectors:
1. Agricultural inputs
2. Agricultural production
3. Agro-processing
4. Marketing and trade
These sub-sectors contribute to adding value and utility to agricultural goods. Agribusiness has emerged as a specialized field within management sciences, focusing on activities and linkages, both backward and forward, related to production, processing, marketing, trade, and distribution of food, feed, and fiber, along with the supply of inputs and services.
Examples of Agribusiness Ventures
• Vermicompost
• Poultry Farming
• Mushroom Cultivation
• Beekeeping
• Livestock Feed Production

This chapter introduces the genetic, physiological, nutritional, environmental and management factors that determine wool quantity and quality. Breed establishes the genetic ceiling, while age, sex, pregnancy, lactation, nutrition, climate, stress, disease and parasites influence fibre growth. The chapter emphasizes the importance of steady nutrition, particularly sulphur-containing amino acids, for maintaining staple strength and fleece production. It also explains how breeding, husbandry, health management, shearing and preparation interact to determine the final commercial value of wool.

As mentioned above, all the present day Bougainvillea cultivars being grown in India are either exotics introduced from abroad (Africa, USA, U.K., South Africa, Australia, Philippines, Sri Lanka, Jamaica, Canary Island, Singapore, Java, West Indis etc) or developed by concentrated efforts of nurserymen, individuals or scientific institutions. Bougainvillea are widely grown in Indian gardens. There are numerous varieties and cultivars that are important from floriculture point of view. Most of the present day varieties have arisen through bud sports, chance crossing and induced mutation. India is one of the major repository of wide range of genotypes of Bougainvillea and is perhaps the foremost among nations which have done appreciable good work on Bougainvillea. The genetic variation in plants is considered to be an unlimited resource. The main aim of germplasm collections are assemblies of genotypes or populations representative of cultivars, genetic stocks, wild species etc. which are maintained in forms such as plants, seeds and tissue cultures. The primitive cultivars and wild relatives of crop plants constitute a pool of genetic diversity.  The  germplasm collection and conservation of plant genetic resources provide the diverse raw materials for immediate or future breeding programme. Activities that relate to the conservation and use of plant genetic resources include : exploration and collection; characterization and evaluation; conservation; assessment of variation and identification of useful genes; and exchange and genetic enhancement. Germplasm are the basic raw materials, which after proper screening can be utilized either for direct commercial exploitation or can be used in breeding programme for developing new and novel varieties.

Nanofibres are an exciting new class of material used for several value added applications in the field of such as medical, filtration as barrier in composites, garments, wipes, insulation, and energy storage. Special properties of nanofibres make them suitable for a wide range of applications from medicine to consumer products and industrial to high-tech applications. The US - National Science Foundation (NSF) defines nanofibres as having at least one dimension of 100 nm or less (Hegde, 2005). Amongst the various nanostructures that have recently been developed for use in practical applications, nanofibres produced from synthetic and natural polymershave received increased attention due to their ease of fabrication and the ability to control their compositional, structural and functional properties (Burgeretal.,2006).

INTRODUCTION

Jewellery has been a favorite form of adornment since time immemorial in all parts of the worlds and Indian is not an exception. The significance of jewellery in the country is evident from the fact that on many auspicious occasions, jewellery forms a part of gifts. Jewellery has not only been considered for the purpose of adoration, but it can also be sold to overcome the economic crisis. This way, jewellery also serves the purpose of insurance, which can be depended upon. To accentuate their feminine beauty, women use jewellery made of gold, silver and diamonds. Traditionally, jewellery has always been linked with wealth, power and status.

Abstract

This chapter will look at the major reasons why farmers in India are unable to take advantage of Agricultural profession as a mode of generating income and suggest ways to change this by employing new technologies. Agriculture has basic processes which require identifying the season for planting the seeds at the right time, watering the plants to the required level, undertaking maintenance for the different plants and then finally harvesting at the right time to ensure that the effort that has been put into the agricultural process results in useful output. In business terms the output when it is valued in terms of money, should enable the farming business to sell their output at a certain price that will enable them to pay off the money that has been used for setting up the crop for that cycle. This chapter will underscore the valuable contribution of remote sensing data in farming to enhance operational decisions. We will look at how low-cost technologies can be implemented into the existing agricultural extension activities and help farmers make better decisions that will enable them to be more business oriented. It is envisaged that incorporating high technology-based data into simple to understand terminology willhelp reduce the burden on farmers. This is due to the lack of knowledge but also due to the low volume of information that is possible to be fed to the farmers through the agriculture extension network in the country. However, due to the varied nature of farming in India it is difficult for extension officers to specialise but concentrate their efforts on widely utilised crops in an area. The following figure below explains in simple terms how the cycle of activities occur in a farmer’s world and where business decisions are taken that will have an impact on the profitability.

Our animal companions are our family members. We want the best for them and want them to be healthy and happy. However, just as it is with everyone else, our companion animals can also fall ill and suffer from emotions such as grief, fear, and anxiety. And while we follow all expert medical advice, sometimes we may wish for something more – something that will make life easier for them as well as us. This is where the concept of energy healing for animals comes in – to comfort and support our animal companions. With joy, we watch them relax with a sigh; we see our nervous dogs calm down, and those recovering from an acute illness get back on their paws in no time. Energy healing for animals involves a holistic approach to ensure the physical, emotional, and spiritual well-being of our animal friends. It is based on the fundamental concept that just like us, our animal companions too have a subtle energy layer, and they too have vital life-force energies or Prana or Qi. And just like us, they, too, have chakras and meridians through which the Qi flows. Energy healing is a set of powerful techniques practiced to calm and restore the balance of the body. This system is largely based on the removal of energetic blocks and helps restore the body’s energy levels. It is crucial for those living with companion animals to understand the importance of energy healing for their animal companions, as it encompasses a broad range of alternative and complementary therapies designed to support the natural healing process of animals. Here are some proven, popular, non-invasive energy healing techniques that bring relief and comfort to companion animals.
1. Animal Reiki: The word Reiki means “mystical energy.” The system of Reiki for healing was revealed by Japanese Buddhist practitioner Mikao Usui in the early 1900s. And while it was initially meant for humans, practitioners soon discovered that animals responded much more swiftly and effectively to this gentle, non-invasive energy work.
2. EFT Tapping: This involves tapping on specific points on the body to free up emotional blocks. EFT Tapping for animals brings powerful transformations when an animal is struggling with emotional distress, such as grief over the loss of a loved human or animal.
3. Scalar Wave Healing: Scalar Wave was discovered in the 1900s by James Maxwell and later Nicolas Tesla. Scalar Wave harnesses the healing power of high vibrational frequencies meeting to create a standing wave, and practitioners use this to bring about healing at a cellular level.
4. Shamanic Healing: In this ancient technique, practitioners work with the elements of nature, such as plants, trees, and stones, as well as beings in other dimensions, to bring about healing. Shamanic healing can reach beyond space and time and has been very effective in releasing old trauma or emotions that are often hidden beneath layers of survival mechanisms.
5. Healing Mantra: Ayurveda, the Indian system of medicine, advocates about different types of Chikitsa. Daivavyapashraya Chikitsa is one of the treatment approaches concerned with Spiritual way of treatment. It includes so many approaches, amongst all Mantra Chikitsa is described in Ayurveda at various places as a potent approach. It is discussed for both the healthy and unhealthy conditions. Mantra comes from Sanskrit word which means sacred message or text, spell. The word Mantra is derived from Man+Tra, man—mananaat---just by chanting and tra—trayate---- we can protect ourselves. Means, just by chanting one can save himself in the universe. i.e. it is saved from onset of disturbances. Mantras are the words loaded with power and sounds capable of penetrating our body into deep levels. Mantra chikitsa is the ancient science originated from Vedas, this is a parallel science to Ayurveda also called alternative medicine system.Mantra Chikitsa is one among the Daivavyapashraya Chikitsa highlights the importance of concept of Mantra. In Atharva Veda and Kaushikasutra, the two most ancient and authentic sources of Daivavyapashraya. Mantra Chikitsa is mainly used for both preventive and curative aspect. It is also used for the enhancement of the Gunas of Aushadhi. Effect of Mantra is described as Prabhavajanya action. Prabhava means the specific and characteristic action of substances, it is called as Acintya. Mantra Chikitsa cure the Karmaja Vyadhi and Agantuja Vyadhi. In the Vedic period, Daivavyapashraya Chikitsa was followed in various rituals.

13.1 Introduction and Physical Principles

A microscope is a tool that enables the user to see objects at a magnification greater than the actual specimen. Resolution and magnifying power are the two integral aspects of microscopy. Resolution is a measure of capability of an image forming system to separate images of adjacent objects. The resolving power (8) is numerically defined as d = 0.61l/n sin a, where,  l is the wavelength of the light, n is the index of refraction of the medium between the specimen and lens, a is half the angle of the cone of light from the specimen plane accepted by the front surface of lens and n sin a is the numerical aperture (NA). The NA represents the light gathering power of the lens aperture or in other words, the measure of obliquity of rays which the lens can accept and utlilize and is limited by blurring of image due to spherical aberration of the lens.
