Hazards to mental health include a range of circumstances that may affect a person’s mental health. A complex and multidimensional component of total health, mental health is impacted by biological, psychological, social and environmental variables. Promoting mental wellbeing and avoiding mental health difficulties need an understanding of these risks and taking appropriate action. Global initiatives to promote health continue to overlook mental health. People with mental health disorders frequently face serious human rights abuses, discrimination and stigma, regardless of advancements in certain nations. More than 80% of those with mental health issues, among them with neurological and drug use problems, lack access to any kind of high-quality, reasonably priced mental health treatment. Even though there are many effective, economical treatments for mental health issues, there is still a substantial disparity between those who require care and those who have access to it. Coverage of effective treatments is still incredibly low. Mental health conditions have a significant effect on happiness, productivity and overall health. Mental health issues have significant emotional, societal and financial implications. These consequences include those associated with the criminal justice system, medicinal and educational services, unemployment and sick leave.
Adolescent mental illness is more than just being miserable. It may affect a teen’s life in many ways. Young people who are mentally ill may have difficulties making decisions, managing their health and succeeding in school. One of the main causes of sickness and impairment in young people are mental health issues, which include childhood epilepsy, developmental disabilities, depression, anxiety, mood, attention and behavioural disorders. Neglecting children’s and teenagers’ mental health and psychosocial development has long-term effects that follow them into adulthood and reduce their chances of living happy, satisfying lives.

Education has continuously evolved in response to technological, economic, and social change. Education 5.0 represents a further transformation toward human-centered, personalized, inclusive, creative, sustainable, and collaborative learning environments supported by intelligent technologies. This chapter examines the evolution from Education 1.0 through Education 4.0 and explains how Generative Intelligence contributes to the emerging Education 5.0 paradigm. Earlier models progressed from teacher-centered knowledge transmission to standardized education, digitally connected learning, and technology-enabled competency development. Education 5.0 extends this evolution by emphasizing meaningful collaboration between humans and intelligent systems rather than simple technology adoption. Generative AI can support personalized content, automated assessment, intelligent tutoring, adaptive learning pathways, multimodal resources, and immersive educational experiences. The chapter also considers the role of AI, IoT, AR/VR, robotics, big data, cloud technologies, and other digital systems in shaping future learning ecosystems. Importantly, Education 5.0 must address data privacy, algorithmic fairness, academic integrity, digital inequality, sustainability, and human control. The chapter presents Education 5.0 as a human-centered transformation in which technology supports creativity, inclusivity, lifelong learning, social responsibility, and sustainable development.

Q.1.    According to Prof. RA Fisher “ANOVA” is the separation of variance assignable to one group of causes from the variance assignable to other group of causes.
Q.2.    The basic purpose of ANOVA technique is to test the equality (homogeneity) of several population means from the same 
experiment.

A Patent is a written document explaining an invention with exclusive right. It is used to protect an inventor/scientist and to prevent other from making profits without permission. It is also used as an authority paper permitting license holders to duplicate the results. A patent application requires a combination of legal documentation and technical papers. This issue makes patent writing a very different writing style.

In India, patent applications can be filed by a patent agent or an individual having some scientific and technical background to understand the invention. However, no one can understand the invention better than the inventors themselves. Document preparation requires healthy discussions between the inventor and agent. For inventors, a good understanding on patent writing style can greatly facilitate the documentation process. Before filing the patent application inventor must be sure about that the subject is eligible for patent protection, the invention has something new, the invention is not obvious and is not easily predictable from general consensus, and the invention has practical application.

Over the years synthetic pesticides like herbicides, insecticides nematicides etc. have been used to improve crop yield. Indiscriminate application of pesticides ultimately leads to their excess discharge into water bodies during rainfall and causes death of fish and other aquatic life. Also consumption of seafood/fishes may cause biomagnification of chemicals in human body and leads to several lethal diseases like cancer, diabetes, neurodegenerative disorders like Parkinson, Alzheimer, and amyotrophic lateral sclerosis (ALS), birth defects and reproductive disorders. Likewise synthetic pesticides also damage soil texture, soil microbes and soil fertility. Their residues enter into plants and animal systems and further move into animals or humans body through food chain.

With increasing fish culture activities several bacterial diseases causing morbidity and mortality in fish have been reported in tropical and subtropical aquaculture systems. Common and major diseases are due to motile aeromonads, Vibrios and Pseudomonas. However, bacterial diseases of minor nature have also been reported from aquacultural systems. In the last two decades several new diseases due to Streptococcus sp, Edwardsiella and Ricketsia have also emerged.

Bacteria can cause disease either as primary pathogens or as secondary opportunistic invaders. Bacterial diseases in fish can be broadly classified as surface ulcerative, acute systemic and chronic granulomatous types (Table 1, Plates 4 and 5). Surface ulcerative types of diseases are characterized by hemorrhagic surface ulcers and are caused by species of Aeromonas, Pseudomonas, Vibrios, Flexibacteria and Myxobacteria. Surface ulcerative disease conditions at times develop to acute systemic disease. Acute systemic disease are characterized by the presence and proliferation of bacteria in internal organs like kidney, heart, spleen, blood and other visceral organs. These diseases produce significant necrotic changes in all affected organs and can cause mortality in a short time scale. Bacterial hemorrhagic septicemia caused by Aeromonas hydrophila is a major problem in carp farms. Chronic granulomatous type of disease conditions are characterized by the formation of granulomas or nodules with the initiating bacteria in the centre. These conditions will not produce mass mortality but can produce chronic low levels of mortality and can significantly reduce growth.

Introduction 
Fossil fuel consumption is associated with a number of grave problems, including economic distress and increased greenhouse gas emissions that cause global warming. The world’s population and environment are deeply concerned about these issues, which are a result of rising greenhouse gas emissions and the depletion of fossil fuels. Furthermore, there has been much discussion about the effects of relying so heavily on petroleum-derived fuels on the environment, the economy, and energy efficiency [1]. According, high process costs, inadequate infrastructure, and other technological challenges impede the manufacturing of second- and third-generation biofuels [2]. The main role of enzymes and other microorganisms during fermentation is as a catalyst to speed up the process of turning saccharides into alcohol. In this kind of biofuel production, lignocellulosic and algal material make up the majority of the biomass used to produce ethanol. The biochemical variety of microalgae is employed in numerous biotechnological and commercial applications [3]. The use of non-usable biomass has been enhanced with each new generation, which lowers production costs and speeds up the manufacture of biofuels. A wide variety of biofuels, such as biogas, bioethanol, biohydrogen, and biodiesel, can now be produced thanks to the application of nanotechnology. In order to convert triglycerides into biofuels, two important chemical events must occur: trans-esterification and esterification [4]. The majority of the nano-catalysts needed to produce biofuel come from microbial fuel cells. Nanoparticles, nanosheets, and nanotubes are examples of these nanocatalysts [5]. The utilization of nanotechnology in the biofuel production process holds promise for enhancing the effectiveness of current procedures. Compared to the production of biofuels, the synthesis of nanoparticles is much more interesting due to the potential applications, challenges, and opportunities that it presents [6]. Here, we review the literature on the application of nanotechnology to improve bioenergy production from algae processing. The different kinds of nanoparticles, including metallic, magnetic, metal oxide-based, and carbon nanotubes that are utilised in the production of bioethanol and biodiesel are covered on this page. A focus is placed on the application of these nanomaterials and how they affect the extraction and transesterification of lipids [7]. This chapter makes the connection between the advancement of nanotechnology and its contribution to the creation of a more efficient and sustainable technique for processing algal biomass to produce bioenergy.

INTRODUCTION

The North-Eastern Himalayas comprise of eastern-Nepal, entire Bhutan, parts of North Bengal and the eight states of North-East India viz. Arunachal Pradesh, Assam, Meghalaya, Mizoram, Nagaland, Manipur, Sikkim and Tripura. The region is characterised by diverse agro-climatic and geographical situations. This has a predominantly humid sub-tropical climate with hot, humid summers, severe monsoons and mild winters. The total forest covering this part of India is 17.50 m ha (which includes 8 NE states and hills of West Bengal) which is about 65.94 per cent of the total geographical area (FSI 2013), and the rest either under crops or non-agricultural uses or un-cultivated land. The low area under agricultural crops is due to natural corollary of the physiographic features of the region, as major chunk of the land has more than 15 per cent slope, undulating topography, highly eroded and degraded soils, and inaccessible terrain. Continuous depletion of the forest cover in the region due to shifting cultivation, firewood, and timber collection is posing the most crucial problem resulting in poor soil health and the resultant environmental degradation. In order to overcome these problems the farmers of the Eastern Himalaya have evolved various types of crop rotations in consonance with the varied environmental conditions and agronomic requirements with tradition by practising different approaches since ages. These practices so developed through major and minor adjustments in land use strategies are mostly sustainable from ecological point of view (Dash and Mishra 2001). 
The practises of agroforestry in this region exhibit a great deal of variation in crop diversity which is influenced by the crop composition and crop rotation. Along an altitudinal gradient, diversity in agroforestry practices is influenced by variation in ecological factors and difference in agricultural practices. Agroforestry has the potential to improve livelihood as it offers multiple alternatives and opportunities to farmers to improve farm production and income and also provides productive and protective (biological diversity, healthy ecosystems, protection of soil and water resources, terrestrial carbon storage) forest functions to the ecosystems. It is accepted as the sustainable management system that encompasses the variety and variability of animals, plants and micro-organisms which can be combined together to derive key functions of the agro-ecosystem, its structure and processes for, and in support of food production and food security. It is promoted widely as a sustainability-enhancing practice that combines the best attributes of forestry and agriculture. This practice is now recognized widely as an applied science and is instrumental in assuring food security, reducing poverty and enhancing ecosystem resilience at the scale of thousands of smallholder farmers in the tropics (Sharma et al. 2007). Therefore, strengthening linkages between knowledge systems using “Community” participatory management approaches is now seen as critical for sustainable forestry and agroforestry systems (Adhikari et al. 2007; Dhakal et al. 2007; Ramakrishnan 2007). 
The mountain communities of eastern Himalayan regions have also adopted diverse agroforestry systems as their land use. Environmental, biological, socio-cultural and economic variation existing in the eastern Himalayas have led to the evolution of diverse and unique traditional agro-ecosystems, crop species and livestock, which facilitate the traditional mountain farming societies to sustain themselves. Appropriate agroforestry systems have the potential to check soil erosion, maintain soil organic matter and physical characteristics, augment nitrogen build-up through nitrogen fixing trees and promote efficient nutrient cycling (Patiram et al. 2003).These systems have today become an established approach of integrated land management system not only for renewable resource production but also for ecological consideration (Saha et al. 2012).

Abstract

In nature the roots of most of the plants are infected by fungi to form mycorrhizal associations, which play a central role in nutrient capture from the soil. These fungi are found in almost every terrestrial ecosystem; even in pioneer zones or very saline environments, and are reported to represent the second largest biomass component of many terrestrial ecosystems. Mycorrhizal associations are found in a broad range of habitats ranging from aquatic to deserts and alpine altitudes. In natural ecosystems mixed population of mycorrhizal fungi co-exist, with certain fungi becoming dominant in a particular patch and subsequently being replaced as environmental conditions change. Once this equilibrium is disturbed, the population dynamics is disrupted and a biomass may develop towards a few or even for one dominant fungus. Different species of mycorrhizae respond differently in response to the environmental conditions. In the present paper, all major types of mycorrhizal associations in different ecosystems are discussed.

9.1 Introduction

Garlic (Allium sativum L.) is one of the important bulb crops grown and used as a spice or condiment throughout India. It is derived from two words gar meaning spear and lic meaning herb. It is also important foreign exchange earner for the country. Garlic has higher nutritive value than other bulb crops. It is rich in proteins, phosphorous, potassium, calcium, magnesium and carbohydrates. Healthy garlic bulbs contain allicin, a colourless, odourless and water-soluble amino acid. On crushing the garlic bulbs, the enzyme allinase breaks down into allin to produce allicin of which the principal ingredient is odoriferous diallyl disulfide. Garlic contains about 0.1% volatile oil. 

Introduction

Market access and supply chain innovation are two critical pillars that underpin the success and sustainability of agricultural produce in today's interconnected world. As the global population continues to grow, along with increasing consumer demands and evolving market dynamics, ensuring efficient access to markets and implementing innovative supply chain practices have become burning imperatives for agricultural producers worldwide.

Disorders of Children and Youth
Although it is sometimes assumed that childhood and adolescence are times of carefree bliss, as many as 20% of children and adolescents have one or more diagnosable mental disorders. Most of these disorders may be viewed as exaggerations or distortions of normal behaviors and emotions. Childhood mental and developmental disorders encompass neurodevelopmental, emotional and behavioral disorders that have broad and serious adverse impacts on psychological and social wellbeing. Children with these disorders require significant additional support from families and educational systems. These children are more likely to experience a compromised developmental trajectory, with increased need for medical and disability services, as well as increased risk of contact with law enforcement agencies (Fergusson and others, 1993).
Like adults, children and adolescents vary in temperament. Some are shy and reticent; others are socially exuberant. Some are methodical and cautious and others are impulsive and careless. Whether a child is behaving like a typical child or has a disorder is determined by the presence of impairment and the degree of distress related to the symptoms. For example, a 12-yr-old girl may be frightened by the prospect of delivering a class report in front of her class. This fear would be viewed as social phobia only if her fears were severe enough to cause significant impairments and distress. The mental disorders that children can develop are commonly divided into two groups: disruptive or externalizing behavior disorders (e.g., attention-deficit hyperactivity disorder, conduct problems) and emotional or internalizing behavior disorders (e.g., anxiety, depression). In this unit we would focus on types of internalizing and externalizing disorders in children. We will also discuss in depth the etiology and treatment involved in these disorders.

Introduction

Geomorphology is the study of earth’s landscapes over time and space, and involves an analysis of both its surface features as well as the processes responsible. Historically, the subject evolved through monumental studies on supposed evolution of the landscape, based on intuitive knowledge of the researchers on landscape response to endogenic and exogenic forces, as well as visions of possible changes over a time scale of centuries to millennia or more. Too much emphasis on the study of possible landscape evolution in an era of little technological back-up facilities meant that the discourses were largely philosophical in nature, with fewer measurable parameters to substantiate the concepts or the reasoning, although reflecting deep understanding of the researchers involved. As older concepts began to be confronted with newer ones, and applied aspects started receiving greater attention, a need was felt for quantification of the features and processes. This was more so for an understanding of the fluvial landscape, although aeolian and other process-based studies also gradually incorporated quantitative analysis as a means of understanding the landscape. Despite the awareness, lack of adequate equipment hindered the progress of quantification in the pre-World War II period.

Analytical testing provides objective evidence of the composition, safety, physical structure, and sensory quality of ice cream. This chapter introduces the major analytical approaches used in industrial ice cream manufacturing, including chemical, physical, microbiological, and sensory evaluation. Important parameters such as fat, milk solids-not-fat, protein, sugars, ash, acidity, pH, overrun, meltdown, fat destabilization, texture, and product weight are discussed. The chapter explains how different tests support routine quality control, product development, troubleshooting, research, regulatory compliance, and shelf-life studies. It emphasizes that no single analytical parameter can define overall quality. Effective product evaluation requires integrated interpretation of chemical, physical, sensory, microbiological, and storage data.

Synonyms: Pearl's disease, scrofula

It is a chronic insidious contagious disease of man and animals caused by tubercle bacilli characterized by development of tubercles in lung tissue, lymph nodes or other organs resulting in caseation and calcification. The tubercles are frequently located in lungs and lymph nodes. But they may be formed in the liver, spleen, intestine, peritoneum, meninges and long bones. It is a zoonotic disease. Bovine tuberculosis, caused by Mycobacterium bovis (M. bovis) is considered as the serious epizootics of animals and humans. Bovine species are natural hosts to the disease, but a wide spectrum of domestic and wild animals, as well as man, can be infected. Animals reported as having been infected with M. bovis include North American bison (Bison bison), buffaloes (Syncerus caffer), elk (Cervus elaphus), domestic and wild pigs domestic (Sus scrofa), goats (Capra hircus), camels (Camelus bactrianus), dogs (Canis familiaris), cats (Fells catus), sheep (Ovis aries), possums (Trichosurus vulpecula), badgers (Meles meles), mink (Lutreola vison), ferrets (Putorius furo) and non-human primates. All species are not equally susceptible, and are often grouped into spill-over (end) hosts and maintenance hosts. Cattle and other bovine species are considered the primary and most well-known reservoirs or maintenance hosts. In countries where maintenance hosts are present endemically in the wild, infection from these populations to domestic cattle or other farm animals is difficult to avoid. In Africa, bovine TB primarily affects cattle; however, infection in other farm and domestic animals, such as sheep, goats, pigs, dogs and cats, is not uncommon. Wild ruminants and carnivores are also affected and are the natural reservoirs of the infectious agent in the wild. Man is also susceptible to the disease, the highest risk groups being individuals with concomitant HIV/AIDS infection. In Africa, human TB is widely known to be caused by M. tuberculosis; however, an unknown proportion of cases are due to M. bovis. This infection in humans is underreported as a result of the diagnostic limitations of many laboratories in distinguishing M. bovis from M. tuberculosis. TB is a neglected public health problem and accounts for about 25% of all avoidable adult deaths in developing countries. It is of socio-economic significance, as it can affect international trade in animals and animal products. Many factors account for the failure of developing countries to control and eradicate bovine TB, many of them politico-economic. Added to the high costs of a sustainable testing programme are problems of social unrest due to political instability and ethnic wars, resulting in the displacement of large numbers of human and animal populations; lack of veterinary expertise and communication networks; insufficient collaboration with bordering countries and hence a lack of quarantine; and smuggling of live animals across state boundaries. Scarce human and financial resources are often absorbed by action against the high incidence of other acute and fatal diseases, such as contagious bovine pleuropneumonia, foot and mouth disease, African and classical swine fever and parasitic diseases. The primary sources of infection for humans are consumption of unpasteurised milk and close association between humans and animals. Rural inhabitants and some urban dwellers in Africa still consume unpasteurised and soured milk potentially infected with M. bovis. Milk borne infection is the main cause of non-pulmonary TB in areas where bovine TB is common and uncontrolled.

Introduction

Okra (Abelmoschus esculentus (L).is a cross pollinated vegetable crop. Okra originated near about Ethiopia& its cultivation became widespread in North Africa and the Middle East (Lamont, 1999; Tindal, 1983). Okra is grown commercially in many nations, such as Ethiopia, Cyprus, India, Bangladesh, Afghanistan, Pakistan, Turkey, Iran, Western Africa, Yugoslavia, Myanmar, Japan, Malaysia, Thailand, Brazil, Southern United States, and Ethiopia (Purseglove, 1987; benjawan et al. 2007; Qhureshi, 2007). It is a widely used, high-valued vegetable crop that is commercially grown for its tender pods during the spring, summer, and kharif seasons. Okra has high moisture content, making it a good source of vitamins, minerals, and mucilage. Okra is cultivated and consumed commercially throughout the year in many different places of India. 

Resistance to diseases in plants may be enhanced by incorporating resistance genes in susceptible cultivars and this disease management strategy is considered to be the most desirable one. But unavailability of reliable sources of resistance and the requirement of long periods for development of cultivars with built-in resistance have limited the usefulness of this approach. Employing genetic engineering techniques for obtaining resistant cultivars appears to hold promise. However, in the light of expression of concern for the long term effects of genetically modified crops and plant products in several countries, the feasibility of exploiting the genetic engineering methods remains a question mark. In this context, the possibility of inducing natural disease resistance (NDR) mechanisms operating in existing cultivars with high yield potential to provide protection to crops and harvested produce against diseases, has attracted the attention of researchers in several countries. This approach does not involve the introduction of any foreign gene into the plant, but it regulates the expression of defense genes in the susceptible plants. Furthermore this approach is as safe as the use of genetically resistant cultivars for the preservation of environment, since the same mechanisms of resistance are activated in plants with either genetic resistance or induced resistance. Intensive research is being carried out to select effective agents that can be used as inducers of resistance in crop plants to contain various diseases, as alternatives to the development of resistant cultivars through conventional breeding and genetic engineering methods

1. Morphology of Bacteria
Structure of Bacteria
Bacteria are very small with a diameter of 0.5 – 1 μm in size. Due to this small size the surface area / volume ratio is very high compared to that of large organisms of similar shape. The large surface area compared to a small volume facilitates easy nourishment of all areas of the cell. So there is no circulatory mechanism to distribute the nutrients and there is little or no cytoplasmic movement within the cell.
i) Shape
Bacteria exhibit three types of morphology;
• Spherical - cocci (coccus) - Greek word kokkos, meaning a berry
• Straight rods - bacilli (bacillus) - Latin word bacillus, meaning a stick
• Helically curved rods -spirilla (spirillum)
Variations in these basic forms are also seen. Eg: cocobacillary, ovoid and filamentous.
