Bioremediation and Detoxification of Asbestos from Soil
Asbestos is referred to as magic mineral and used as excellent building material. It finds its application in wide range of products such as floor tiles, pipes, paper, rope, cloth, insulated partition board, etc. On average, India uses 3, 50, 000 tons of asbestos annually and asbestos fibers readily undergo weathering releasing them into soil, water and air. Occupational and environmental exposure to this asbestos is leading to asbestosis (asbestos-related disease), lung cancer, and heart failure. Considering the serious health risk, countries like Australia, Brazil, and Canada had banned the use of asbestos. As asbestos is extensively used in construction of buildings, the demolished materials are dumped in the soil and thus it finds its route in soil as pollutant. Soil borne microbes like bacteria, fungi and lichens are found to be best means to reduce the toxicity of asbestos. These microorganisms remove iron from asbestos and reduce its toxicity. Another most effective bioremediation approach is phytoremediation to clean up the soil wherein vegetative cover on contaminated soil can remove iron and breaks down asbestos as source of inorganic nutrient. The main advantage of phytoremediation is that it can be extended to any geographical area where plants can grow. This chapter emphasizes various means of use and disposal of asbestos, followed by various means of bioremediation using microbes and plants and as an alternate for the sustainable soil condition.

Bioremediation of Heavy Metal Contaminated Sites Using Phytogenic Nanoparticles
Heavy metals (HMs) accumulate in milieu due to various human activities that persist leading to biomagnification in food chains and cause unpleasant effects on human health and environment. Pollutants such as organic matter and HMs are reme-diated traditionally by chemical precipitation, electrochemical treatment, adsorption, reverse osmosis, ion exchange, coagulation, and photo-catalyzation, remained inef-fective. Use of nanomaterials conjugated with various compounds showed significant reduction in several contaminated sites. However, existing implication of nanotech-nology works with nanoparticles (NPs) synthesis majorly involved the use of chem-ical raw materials and physical methods which are relatively toxic and unstable. Aforesaid difficulties made researchers and entrepreneurs to reconnoitre effective, newer, and novel synthesis approaches for the replacement over older version. During the past decade, to overcome these issues plant-derived NPs are extensively used because of its less cost, efficiency, and eco-friendly in nature. Hence, advanced alternative technology like phytoremediation using nanomaterials with innovative techniques has been a boon for HM remediation. Efficiency of green synthesized NPs is based on redox reactions which makes metals stable facilitated by flavonoids and polyphenols responding to HM-stress. Several metal complexation processes are known to produce phytochelatins or other metal-chelating peptides helping the biore-mediation of HMs. Current chapter throws light on adaptive mechanism employed by NPs coupled with plant or microbial extracts in overcoming the HM stress. Further-more, here we also focus on the possible mechanism and interaction between NPs and HM in minimizing severity of polluted sites with many examples.

Child Mental Health in the Milieu of Online Education
The aim of this chapter is to examine the impact of online education on mental health of children, and explore methods to improve the same. With the advent of COVID-19 pandemic, major overhauls were made in day-to-day life including work, home, and education. Shift to online mode of instruction became the primary, if not the only, channel of education. This drastic shift has led to issues like limited social interaction, learning gaps due to insufficient in-person interaction, excessive screen time on devices, and decreased physical activity, which can impact mental health of children. This chapter will explore the impact of online learning on the mental health of children from both mental ill-health and well-being perspectives, the role of parents, teachers, and educational systems, and challenges and opportunities presented by the situation. Further to this, the ways to safeguard and improve mental health of children in the milieu of online education will be discussed.

Misuse of Internet Among School Children: Risk Factors and Preventative Measures
The Internet has been one of the most transformative and rapidly growing technologies. In recent years, it has improved the quality of life in areas such as communication, education, recreation. On the contrary, there are growing concerns about the use of the Internet that have created adverse consequences in the areas of social life, interpersonal relationships, family environment, and school activities. School-going children were vulnerable to such unhealthy outcomes due to readily available high-speed Internet and ease of access to different Internet platforms, which resulted in risky behaviours, decreased academic performance, poor nutrition, decreased sleep quality, and a high incidence of inter-social conflicts. While the majority of the research has focused on the adolescent population in terms of problematic Internet use, only a few studies have identified the vulnerabilities of school-going children in the same context. The research also confirmed that the risk factors for problematic Internet use start as early as middle childhood. Heightened risky use of the Internet was observed in children with neurodevelopmental concerns. This study explores risk factors associated with problematic Internet use among school-going children, identifying relevant warning signs followed with preventative measures.

Psychogenic Non-epileptic Seizures in Children: Prevention and Intervention Strategies
Psychogenic non-epileptic seizures (PNES) often get misdiagnosed to be epileptic seizures, and the price that is paid for the same by the patient and the family is huge. It is called by multiple names such as pseudoseizures non-epileptic attack disorder, dissociative seizures, and functional motor disorder. Not only is it difficult to identify the disorder, but it also poses an added difficulty with comorbid epilepsy. Adding on to these, it becomes difficult for both the healthcare provider to offer psychoeducation and the family to accept since no tangible evidence such as scans portrays any abnormality. Though in a simple manner it can be said this disorder presents itself like epileptic seizures but has no neurological base, explaining the same to the patients and their family is not as simple. However, surprisingly the prognosis for PNES is better for children. This chapter thus focuses on aspects that are essential for the treatment of the disorder and prevention. In particular, the manifestation of PNES in children is discussed by introducing the disorder with epidemiological information. Further clinical picture, etiology, diagnosis and prevention and intervention are discussed. Although there are limited studies that exist on the treatment of the disorder in the pediatric population, their outcomes to reduce PNES symptoms are significant. Hence, the chapter makes an attempt to review these studies in detail and mention highlights of these studies that contribute to a reduction in the symptoms. Finally, the chapter concludes with a biopsychosocial model that explains the relationship between these factors and PNES and how this can be used in prevention.

Negotiating Inclusion: Minority Institutions and Constitutional-Legal Dimensions in India
The chapter Negotiating Inclusion: Minority Institutions and Constitutional and Legal Dimensions in India is based on the premise that special provisions for inclusion of minority groups were one of the contested topics that have been negotiated in India since independence. The present chapter critically explores the two main sites of negotiation: Constituent Assembly Debates and the cases involving the question of minority rights to culture and education as adjudicated by the Indian courts. In doing so, the paper undertakes an examination of the logic of state recognition and reservations, voiced by nationalist leaders and members of the Constituent Assembly, who were apprehensive that the provisions on minority accommodation may not be compatible with Indias secular credentials. Constitutional provisions, specifically the fundamental rights embodied in Articles 29 and 30 were further debated and re-interpreted by the High Courts and Supreme Court. Further on, the issue of minority accommodation led to the establishment of institutional mechanisms in India, one such institution being the National Commission for Minority Educational Institutions (NCMEI)-a recent addition in the series of negotiating spaces of the religious and minority communities in India. A thorough examination of the functioning of the NCMEI, an institution which remains understudied, may inform new avenues into thinking about the sites of minority rights negotiations in India, given the shifting ideological positions at the national level.

Developments in Feeds in Aquaculture Sector: Contemporary Aspects
Aquaculture, one of the largest protein food generating sectors, greatly relies on nutrition. Up to the present time, the dependency of the aqua feed sector on fish meal and fish oil as protein and lipid sources, respectively, was too high, which led to its inadequacy and over-exploitation of marine resources. Recently, numerous researches with locally available feed ingredients have been accomplished. There is urgency for a move from fish meal to plant/terrestrial animal/microbial proteins within the aquaculture industry as over-exploitation of wild fishes has negative ecological consequences. Plant proteins cannot successfully replace fish meal due to poor protein digestibility and essential amino acids imbalance, urging feed concerns to search for cheaper and nutritious fish meal alternatives from animal origin. In order to overcome the indiscriminate use of antimicrobial drugs, the concept of probiotics in aquaculture has received firm encouragement in recent years due to their wise inhibitory mechanisms and safeness. Negative perception for synthetic antioxidants among fish farmers and their unreliable nature has resulted in the research for non-synthetic, food derived antioxidants that could encounter and neutralize the detrimental effects of free radicals. In line with this, there is a strong captivation to research on the individual or synergistic effects of protein hydrolysates, peptide fragments, and free amino acids that could innately exhibit antioxidative activity. Commercialization of economical feeds with antioxidative feed ingredients could strengthen the profits of feed processors. Recent development in the aquaculture sector propelled by the application of biotechnological methods has clearly highlighted the need for development of functional feeds through incorporation of bioactive molecules. In the last few decades, the global aqua feed industry has witnessed milestones in the development of feed ingredients from waste raw materials and sustainable alternatives to antibiotics and chemicals used to tackle the disease outbreak in aquaculture. As the health and immunity of fishes primarily depend on their nutritional pattern, a great research interest is extended on incorporation of biomolecules like single-cell proteins, animal proteins, plant metabolites, biopolymers, and enzymes as feed ingredients to enhance the nutritive quality and immune tolerance in fishes. Besides the focus on the feed ingredients, the modification and development of fermentation strategies for producing probioticbased feed and enzyme-assisted bioconversion into valuable feed ingredients is also gaining more importance. This chapter deals with the recent development in the aqua feed industry with specific reference to the incorporation of non-conventional feed ingredients like animal/microbial proteins, biopolymers, enzymes, and other immunostimulatory compounds in aqua feed and their impact analysis in improving the growth profile and pathogen tolerance in fishes.

Recent Progress on the Development of Chemosensors
Chemosensors are the chemical structures which convert chemical stimuli into responsive form that can be easily detected, such as change of colour, fluorescence, and other electronic signal. Recently, chemosensors development for detection and monitoring of gases has been growing interest due to the significant importance in environmental and biological systems. Subsequently, the development of chemosensors for detection of various gases is considered to be a significant goal in science and among the all gases, carbon dioxide (CO2) is a major public concern due to its role in global greenhouse warming with environmental pollution. Moreover, quite critical level of CO2 in the modern agricultural, food, environmental, oil and chemical industries is dangerous for living beings to survive such high concentration levels of CO2. Therefore, rapid and selective detection and monitoring of CO2 in the gaseous as well as in the liquid phases provides an incentive for development of new methods. The coverage of this book chapter is divided into different sections according to the use of different types of molecular backbones and the detection pathways.

In Vitro Production of Saponins
Plants have been utilized as food, feed, and fodder since the dawn of civilization. Plants are also thought to be a rich source of bioactive compounds with a variety of pharmacological actions. Saponins are one such group of molecules which are present in various plant species. As triterpenoid glycosides, they have a 30C oxidosqualene precursor aglycone moiety (sapogenin), which is then linked with glycosyl residues to form saponin. These saponins have a unique platform in the field of pharmaceutical and nutraceutical industries. Saponins are used for the treatment of various diseases which include cancer, diabetic, cardiac, hepatic, and nervous disorders. The production of saponins through conventional approaches is time-consuming and hard to extract pure compounds, and thus to achieve this, in vitro methods have been developed and enhanced the production and extraction of the metabolites. The present chapter focuses on the in vitro production of saponins through various tissue culture techniques such as shoot, callus, cell suspension, adventitious root, hairy root culture, and applications of bioreactors at commercial level. The chapter also focuses on biosynthetic pathway, extraction methods, and biological activities of saponins.

Environmental Applications of Green Engineered Copper Nanoparticles
Naturally engineered nanomaterials in recent times have myriad potential in different fields. Moreover, green derived nanoparticles (NPs) encourage broader implementation for wider applications. Amongst many metals, copper and its oxide-based nanoparticles (CuONPs) have increased utmost consideration owing to its specific characteristics, abundance, and cost-effectiveness. Major setback of chem-ical and physical methods of synthesising CuONPs involves high cost along with environmental hazards. Aforementioned challenge compelled researchers to explore green synthesised CuONPs that is much cheaper, efficient, economically beneficial, non-toxic, and eco-friendly. Existing plant-based CuONPs have potential efficiency to enhance the toxic effects against the plant pathogens and combating environmental pollution through bioremediation. Several extracts of plant derivatives have been used for the synthesis of CuONPs such as Azadirachta indica, Hibiscus rosa-sinensis, Murraya koenigii, Moringa oleifera, Tamarindus indica, Eclipta prostrate, Olea europaea, etc. Microbes as cell factories are more efficiently used as NPs compared to larger plants such as, green algae Botryococcus braunii, brown algae Macrocystis pyrifera, Bifurcaria bifurcate etc. Bio-based CuONPs have been applied in numerous fields such as pharmaceutical, molecular biology, bioremediation, cosmetics, textiles etc. Several of them also employed in dye degradation, water treatment, food preser-vation, Photovoltaic devices, solar energy conversions, and field emission emitters. However, as in clinical setup due to their efficacy these are exclusively used as anti-cancer, antimicrobial agents. Further, their high antioxidant potential renders them as an invaluable tool for biomedical devices.

Is Mindfulness a Key Characteristic of a Jugaad Leader?
The practice of mindfulness has its roots in Eastern religions. Both Hinduism and Buddhism emphasize the need to be calm and to focus on the present moment. This concentration is called mindfulness. In the Indian subcontinent, there is a specific tradition for innovation and creativity that produces the best possible results, even among resources that are often sparse. This approach is called Jugaad. It is increasingly being used as a management technique. Companies in South Asia are adopting Jugaad as a practice to reduce research and development costs and use unconventional approaches to maximize resources for a company and its stakeholders. Tang (The leaders guide to mindfulness. Pearson UK, Harlow, 2018) noted that mindfulness from a context of jugaad creativity or innovation allows individuals to enter a childlike state of creativity. Mindfulness promotes a directed awareness and allows one to look at problems or issues from different perspectives-not only from a clients or customers perspective, but also from that of a child-encouraging further reflection. A mindfulness approach calms the mind before a creative or brainstorming session, which can foster insight and clear the mind for an aha moment in the jugaad innovation process. Often, a successful jugaad creative process requires breaking down psychological barriers in a team-e.g., fear of doing something wrong, fear of ideas being stolen by others. A mindful approach to such issues helps team members meditate and relax, creating a safer space for creative exploration, as these exercises can teach listening and acknowledgement of each individual. Also, the associated creativity and innovation process helps to understand the problem to be solved and generate ideas from it. The mindfulness approach promotes the flexibility and clarity needed for a jugaad approach (Tang, The leaders guide to mindfulness. Pearson UK, Harlow, 2018). The following are the results of the Jugaad leadership survey conducted among managers in India. Managers felt that Jugaad leadership involves leading by example, appreciation and recognition. Also fundamental is leading with humility, openness to receiving feedback, and awareness of ones own thoughts and emotions. Mindfulness also includes language and behavior, the ability to recognize peoples needs, and an intuition in situations that require change. All of these characteristics make it clear that the Jugaad leader is a mindful person and also show that he or she practices mindfulness while guiding, interacting with, and motivating his or her team members.

Ramifications of Climate Change Induced by Anthropogenic Factors on Global Fish Population Scenario
One of the important consequences of climate change is its effect on the global fish population. Though not very highly pronounced each year, the effect of climate change is of cumulative nature. Global aquaculture is being affected by temperature changes of both water and air. Fluctuations in the ocean surface temperatures, ocean current patterns, wind speeds, and wave directions, all have its impact on aquaculture. Each year we see more and more incidences of extreme weather conditions in different parts of the world, be it in the form of hurricanes, heavy floods, etc. Fishes are subjected to various stress factors which in turn take a toll on its growth and development. This can lead to lower weight gain and increased mortality due to higher susceptibility to diseases. This, coupled with direct unsustainable anthropogenic activities in the oceans and rivers may lead to collapse of the marine and freshwater ecosystem. Recent studies have identified specific regions where marine aquaculture production will be positively and negatively affected. One of the sustainable ways of developing aquaculture in the coming decades would be by developing region-wise strategies to maintain or increase fish population levels and thus meet the global seafood demands even in 2050. The current review is an attempt to assess the effects of ocean warming, ocean acidification, and ocean deoxygenation on the growth, survival, and diversity of marine lifeforms and suggest ways to stop a complete collapse of marine fish population by 2050, the year for which the complete collapse is predicted based on projections.

Children Witnessing Violence in India: Nature, Risk Factors, Impact and Prevention Strategies
Children witness various degrees and intensities of violations and violence along with a hoard of environmental stressors. Such a spectrum of violence includes disturbing family environments, witnessing adults, including parents and family members, indulge in violence and abusive behaviours and direct or vicarious exposure to violence outside the home. The chapter aims to provide an overview of the nature and impact of witnessing violence. The frequency, type, intensity and the child's relationship with the people involved or impacted by the violence can determine the impact on a child's mental health and development. Children may witness distressing events in their daily lives like the loss of a loved one or watching adults take up challenging tasks, which may help them be resilient and learn coping skills with appropriate support. Long-term exposure to witnessing violence and trauma can lead to severe emotional and developmental difficulties. Such direct or vicarious exposure to varying degrees of violence may cultivate a culture of fear, repression and silence around the children. These difficulties may be similar to those of children who are direct victims of abuse. Witnessing violence has also been linked to anxiety and depression. Children growing up in such environments are at higher risk of normalizing violence and growing into abusive adults. Poverty, cultural factors, parenting, schooling, and policies can largely determine such risks for children. The paper discusses the preventive and promotive approaches at the school, family and community levels. Education and empowerment of adults in the child's environment can be the best preventative approach. Existing policies and programmes in India for children need to bring in more robust initiatives to identify, report, prevent and protect children witnessing violence. The needs and concerns of children witnessing violence and prevention approaches should be part of courses in helping professionals training and curriculum. The chapter calls for the necessity of individual and community-based interventions in terms of need-based models for addressing the mental health needs of children. The chapter strongly recommends the need for addressing mental health education for families and schools.

Perspectives and Implications of Probiotics as Beneficial Mediators in Aquaculture Industry
The diseases and nutrient deficiency in fish and other cultured aquatic species are of crucial concern as they cause severe economic loss in aquaculture sectors. The use of probiotics has proven to be an effective option to reduce the infections improve the overall health and enhance the productivity. This review comprehensively brought out significance of probiotics, their mode of administration via encapsulation methods and their mechanism of action reported by several research works. We have also highlighted the other beneficial aspects of probiotics as potent functional agents influencing gut microbiota, competence with pathogenic bacteria, release of antimicrobial secretions and maintain the water quality in environmental friendly manner which ensures sustainable aquaculture and fish farming. This review has also covered up the role of probiotics in wide spectrum of functions such as antiviral and antifungal properties, reducing stress and diseases, modifying the gut microbiota, improving the fecundity, survival and modulating the immune system of the host. We have discussed every aspect of probiotics and correlated with the existing research and review articles till date. However, most of the studies are reported based on the laboratory trials and experiments; commercial and large-scale demonstration has to be scaled up and utilization of them in natural environments like ponds and lakes will be effective way to broaden aquaculture industry.
