Soil conservation in hilly areas

Soil erosion is a major problem on hills because of steep slopes. It has been estimated that about 6 million ha of land requires intensive conservation measures in Himalayan and sub-Himalayan regions of Uttar Pradesh, Uttarakhand, Punjab and Himachal Pradesh. Anthropogenic activities like shifting cultivation, deforestation, over grazing accelerate soil erosion in hilly ecosystem.

Introduction

Climate change specifies long-term shifts in weather patterns, which are measured over decades to millions of years. In modern times, it predominantly concerns the increase in Earth’s average temperature due to human activities, particularly the burning of fossil fuels10. The rise in greenhouse gases such as carbon dioxide, methane, and nitrous oxide traps heat in the atmosphere, leading to global warming. In connection with animal health, climate change affects the ecosystems in which animals live, influencing the availability of water and food, the spread of diseases, and the physiological stress animals endure due to temperature extremes. Domestic animals, mostly livestock, are vulnerable to heat stress and reduced productivity, whereas wildlife faces altered habitats and increased exposure to pathogens. The connection between climate change and animal health is intricate, as changes in temperature, humidity, and weather patterns create new challenges for both domestic and wild species.

It is an inherent, distinctive and implicit human nature to preserve and care for objects that seem unique, rare and adorable. This instinctive desire of the human mind must have invented the concept of museum. The word museum derives from the Greek word “Mousein” which mean “Seat of the Muses”. The muses are the divine patron of arts in Greek Mythology.
A museum by definition is “An institution that houses and cares for a collection of artifacts and other objects of scientific, artistic or historical importance and makes them available for public viewing through exhibitions that may be permanent or temporary (Alexander and Alexander 2008; Kamath et al., 2014). The anatomy museum comes under the category of science museum. Anatomy museum define as a place where bones, models, charts wet specimen of permanent value are kept and displayed. It has to be designed to function as an institute where active leaning can take place (Kamath et al., 2016).
The museums now witnessed a transition from an institute housing a collection of models and artistic sketches to one housing formalin preserved specimens, corrosion casts and plastinates. The contemporary museums have sophisticated interiors, display, lightings and use computerized catalogues and audio-visual aids to teach anatomy.
History
The concept of anatomy museum was first conceived by the Edinburg Surgeons in 1763 A.D. A cabinet with anatomical picture books and few specimens was first prepared and named as cabinet of curiosities. Early museums housing a simple collection of wood, clay, wax or ivory models of anatomical specimens.
The discovery of formalin in 1859 by Alexander Mikhailovich Butlerov was a great milestone in anatomical history and changed the, manner of anatomical specimen presentation. Later on discovery of different methods significantly make transition in the nature of collection exhibited in anatomy museum.

Introduction

Weeds are unwanted plants in agricultural production causing huge losses in crop production system particularly rainfed agriculture. Of the total estimated losses caused in crop production by pests, diseases and weeds in the world, the weeds alone are responsible for one-third of it. Weeds interfere with crop growth and cause an yield loss to the tune of 10% of crop production which amounts to a total loss of about 20 million MT of food grains, valued at over Rs.10,000 crores, at current prices in India. Besides, losses of similar magnitude are experienced in vegetable, fruit and plantation crops. The losses inflicted on biodiversity, environment and health are considerable and have not been quantified scientifically.

In November 1992 a document entitled Warning to Humanity was released, signed by 1500 scientists from around the world, including 99 Nobel laureates, and the Director General of the United Nations Educational, Scientific and Cultural Organization (UNESCO). The document stated that “human beings and the natural world are on a collision course,” which “may so alter the living world that it will be unable to sustain life in the manner that we know.”

For maximization of productivity in any kind of poultry venture the knowledge on the behaviour of birds and its application play very significant role. Behaviour is the reaction of the whole organism to certain stimuli, or the manner in which it interacts to its environment. Behavioural patterns are not inherited as such, but develop through the process of growth and get differentiated under the influence of genetic and environmental factors. Primary function of behaviour is to enable the bird to adjust itself to some changes in condition, whether external or internal. Most animals have a behavioural pattern which can be tried out in a given situation and in this way they learn to apply one or the other according to that which produces the best adjustment.

The Aquatic Resources Research Institute (ARRI) was established to conduct research & answer important impending questions associated with the nation’s aquatic resources, like conservation of marine organisms, marine science, oceanography, aquaculture, biotechnology etc. It also works for transferring or sharing the knowledge to public, for guiding towards sustainable development.

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.
