Risk management of technological accidents triggered by natural-hazards (Natech): A review of relevant indian legislation
subject: Climate Change; Disaster Management; Indian Legislation; Natech Risk; Risk Reduction Measures; Safety of Hazardous Industry
description: The ill-effects of technological sites on the environment have been researched substantially across the world with particular reference to pollution. However, the threats posed by the environment to technological sites have rarely been studied. Such events, where natural forces trigger technological accidents, are called Natech accidents. It has been observed that developed countries are aware of this emerging hazard and they have responded to it by creating various legislative frameworks for managing Natech risk. In contrast, in developing countries, it has not yet received due attention. The present study has been done to understand the Indian perspective of the legal framework for Natech risk reduction. The study revealed that India has an elaborate legislative framework for disaster risk identification and management. Though there is attention to routine disaster risk, the risk from natural forces to the technological sites is rarely considered. Apart from recognizing natural forces as a threat, no specific legislation is available for Natech risk reduction. A developing country like India must manage the risk posed by natural forces to its technological infrastructure. There is a need for specific legislation to manage Natech risk, which will be an initiating force for the state of the art Natech risk management. 2021, World Research Association.

Reproductive health vs overall well-being: systematic review of studies on women migration and health care utilization
subject: Health care Utilization; Health service delivery; Reproductive health; Women migrant
description: Purpose: Sustainable development goals (SDGs) recognize the importance and interrelation between health and migration. Women migration and health is well researched, yet less attention is paid to their healthcare utilization, especially with regard to overall health and well-being. This paper aims to highlight the gap in the existing literature on health care utilization by women migrants. Design/methodology/approach: A systematic review was carried out following the PRISMA guideline. For the review, the literature was taken from three electronic databases, which were Springer Link, Taylor and Francis and PubMed. From a total of 1,575 studies, seven studies cleared the eligibility screening. Findings: Of seven studies, five were found to focus on the sexual and reproductive health of the women migrants than their general health and well-being, and less attention is paid to health promotion and illness prevention beyond reproductive and sexual health. While, studies on general health have focused on the influence of health status on health care utilization and the influence of health insurance in health care utilization. The review has revealed the disparities faced by migrant women in different countries while seeking health care. Originality/value: Studies on women migration and health care utilization have largely focused on the reproductive and sexual health needs of women, and this overemphasis often undermines their accessibility and affordability to overall health and well-being. Therefore, the present study has moved away from the concept of sexual and reproductive health tot that of overall health and well-being of women migrants. 2021, Emerald Publishing Limited.

subject: Abusive relationship; Dating violence; Intergenerational continuity; Trauma; Violence against women
description: Dating is hushed within the Indian society and this silences the trauma Indian women face in their pre-marital romantic relationships. This study delves into the nature and cyclic patterns that influence an abusive dating relationship. Are abusive behaviours passed down generations and learned in early childhood? What is characterised as an abusive relationship? This article discusses the experience of 11 Indian women in the age range of 20- 25 years who were subjected to abuse within their dating relationship. Thematic analysis was used to arrive at the organizing themes including factors related to perpetrators and victims, characteristics of abuse, families of victims and other psycho-social factors. 2021 Tata Institute of Social Sciences.

Application of Epoxy-Asphalt Composite in Asphalt Paving Industry: A Review with Emphasis on Physicochemical Properties and Pavement Performances
description: One of the failure mechanisms associated with asphalt paving layers, especially on steel deck bridges, is large permanent deformation, which adversely affects its long-term performance in service. Thus, epoxy resin was introduced in asphalt paving industry to tackle permanent deformation of asphalt mixtures due to its thermosetting nature. In this review, epoxy resin as a dominant component of the epoxy-asphalt composite system was first considered, followed by a discussion on its curing methods and curing mechanism. Furthermore, the physicochemical property and mechanical performance of epoxy asphalt and epoxy asphalt mixture were thoroughly examined. Crosslink density of epoxy asphalt dictates its viscosity and thus the allowable construction time. Phase separation and dispersion of asphalt particles in the epoxy matrix was observed for epoxy-asphalt composite, and it showed superior elastic behavior and deformation resistance capability when compared with conventional asphalt materials. Furthermore, epoxy asphalt mixture exhibited significantly higher compressive strength, much better rutting resistance, and superior durability and water resistance properties. However, its low-temperature cracking resistance was slightly compromised. 2021 Yu Chen et al.

Critical review on arsenic: Its occurrence, contamination and remediation from water and soil
subject: Arsenate [As(V)]; Arsenite [As (III)]; Contamination; Phytoremediation; Toxicity
description: With the increasing pollution in todays world, importance is being given to solve a problem and do it in a sustainable, eco-friendly manner. Arsenic is a class-1 carcinogen and also causes many other side effects to humans, plants and animals. The utilization of arsenic as wood preservatives, pesticides, or its historical overuse by some military units for rice killing operations has led to the increase in the toxic effects of arsenic like its carcinogenicity, decreased immune response etc. Although conventional methods like coagulation, lime softening, adsorption, membrane technology are effective, they have their disadvantages like additional waste generation, causing increased pollution and are expensive. The better alternative is phytoremediation. Appropriate plants like Brassica juncea, Hydrilla verticilata, Pteris vittata L., Vallisneria natans, can be chosen based on the method of the remediation like phytoextraction, phytostabilization and phytofiltration or phytovoltalization. This review provides the list of a few plants which can be likely chosen for the purpose of both water and soil remediation. Advancements are occurring in bioremediation studies with the development of transgenic plants like transgenic tobacco, transgenic Arabidopsis thali-ana for better phytoremediation. Understanding the mechanism employed by the plant for its uptake/detoxification can aid in the enhancement of the process of remediation with the external supply of phosphorus. Along with this, the proper and safe disposal of plants is crucial for the remediation process. In addition, awareness of this solution to the general public is to be made for its effectiveness. : Author (s). Publishing rights @ ANSF.

A review of hierarchical nanostructures of TiO2: Advances and applications
subject: Hierarchical architecture; Morphology; Nanostructures; Titanium dioxide
description: In the past few decades, extensive studies have been carried out on TiO2 nanostructures having hierarchical morphologies and their applications in diverse fields. By controlling the size and composition of the different TiO2 morphologies, new and improved properties have been realized, leading to significant advancements in materials chemistry, in the broad areas of energy and environment. The improved efficiency and wide applications of these materials are attributed to their physicochemical properties such as stability, efficient electronic and ionic charge transfer, higher specific surface area, etc. In this review, we discuss the different morphologies of hierarchical TiO2 nanoparticles and the properties that have been influenced by these morphologies, enabling their diverse applications. Several composites using the different TiO2 hierarchical forms have been synthesized which too find wide applications. The excellent physical properties of zero, one, two, and three-dimensional TiO2 nanostructures, the relationship between the morphologies of TiO2 nanostructures, and their activities in energy and environment applications have been discussed. 2021 The Author(s)

Advances in Carbon-Element Bond Construction under Chan-Lam Cross-Coupling Conditions: A Second Decade
subject: C-N bond formation; C-O bond formation; Chan-Lam coupling; copper mediated; copper-catalyzed; N-arylation
description: Copper-mediated carbon-heteroatom bond-forming reactions involving a wide range of substrates have been in the spotlight for many organic chemists. This review highlights developments between 2010 and 2019 in both stoichiometric and catalytic copper-mediated reactions, and also examples of nickel-mediated reactions, under modified Chan-Lam cross-coupling conditions using various nucleophiles; examples include chemo- and regioselective N-arylations or O-arylations. The utilization of various nucleophiles as coupling partners together with reaction optimization (including the choice of copper source, ligands, base, and other additives), limitations, scope, and mechanisms are examined; these have benefitted the development of efficient and milder methods. The synthesis of medicinally valuable or pharmaceutically important nitrogen heterocycles, including isotope-labeled compounds, is also included. Chan-Lam coupling reaction can now form twelve different C-element bonds, making it one of the most diverse and mild reactions known in organic chemistry. 1 Introduction 2 Construction of C-N and C-O Bonds 2.1 C-N Bond Formation 2.1.1 Original Discovery via Stoichiometric Copper-Mediated C-N Bond Formation 2.1.2 Copper-Catalyzed C-N Bond Formation 2.1.3 Coupling with Azides, Sulfoximines, and Sulfonediimines as Nitrogen Nucleophiles 2.1.4 Coupling with N, N -Dialkylhydroxylamines 2.1.5 Enolate Coupling with sp 3-Carbon Nucleophiles 2.1.6 Nickel-Catalyzed Chan-Lam Coupling 2.1.7 Coupling with Amino Acids 2.1.8 Coupling with Alkylboron Reagents 2.1.9 Coupling with Electron-Deficient Heteroarylamines 2.1.10 Selective C-N Bond Formation for the Synthesis of Heterocycle-Containing Compounds 2.1.11 Using Sulfonato-imino Copper(II) Complexes 2.2 C-O Bond Formation 2.2.1 Coupling with (Hetero)arylboron Reagents 2.2.2 Coupling with Alkyl- and Alkenylboron Reagents 3 C-Element (Element = S, P, C, F, Cl, Br, I, Se, Te, At) Bond Forma tion under Modified Chan-Lam Conditions 4 Conclusion…

Medicinal plants, phytochemicals, and herbs to combat viral pathogens including sars-cov-2
subject: Antiviral agents; COVID-19; Herbs; Medicinal plants; Phytochemicals; SARS-CoV-2
description: The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome corona virus-2 (SARS-CoV-2), is the most important health issue, internationally. With no specific and effective antiviral therapy for COVID-19, new or repurposed antiviral are urgently needed. Phytochemicals pose a ray of hope for human health during this pandemic, and a great deal of research is concentrated on it. Phytochemicals have been used as antiviral agents against several viruses since they could inhibit several viruses via different mechanisms of direct inhibition either at the viral entry point or the replication stages and via immunomodulation potentials. Recent evidence also suggests that some plants and its components have shown promising antiviral properties against SARS-CoV-2. This review summarizes certain phytochemical agents along with their mode of actions and potential antiviral activities against important viral pathogens. A special focus has been given on medicinal plants and their extracts as well as herbs which have shown promising results to combat SARS-CoV-2 infection and can be useful in treating patients with COVID-19 as alternatives for treatment under phytotherapy approaches during this devastating pandemic situation. 2021 by the authors.

title: Evaluation of a gamified learning experience: Analysis of factors that impact the effectiveness of a gamified experience; [Avaliao de uma expericia de aprendizagem gamificada: Anise dos fatores que afetam a eficia de uma expericia gamificada]
subject: Academics; Gamification; Learning; Reaction
description: Gamification has gone through a faddish cycle. It first gained prominence around 2012 and was quickly abandoned, as practitioners did not achieve the outcomes they expected. According to Gartner's Hype Cycle, Gamification is at a point at which one might expect wide scale adoption. However, if history is not to repeat itself and results are to be achieved as theoretically predicted, a deeper understanding of the concept is essential. In the current study, the researchers attempt to evaluate a gamified learning experience. The participants were students of a Master in Business Administration course. The students were asked to participate in a gamified module and relevant data was collected, before and after the intervention. Based on a review of literature, the researchers identified the exogenous variables of Valence, Attitude towards use of Technology and Experience with Technology. The endogenous variables identified included Reaction and Learning. The findings of the study suggest that the gamified module resulted in increase in knowledge and that Attitude, Experience and Valence significantly predicted the Learner's reaction to the experience. The findings of the study provide support to key theories in the area of gamification and insights for practitioners, on the factors to be considered before using a gamifiedlearning intervention. 2021 UNIVERSIDADE FEEVALE All rights reserved.

Review on persistent challenges of perovskite solar cells stability
subject: Commercialization; Pb-toxicity; Perovskite solar cells; Photovoltaics; Stability
description: Today Perovskite solar cell (PSC) has achieved efficiency close to 26%, surpassing the efficiencies of well- known Dye-Sensitized Solar cells (DSSC), CdTe-based solar cells, etc. Ease of preparing perovskite solutions and convenient deposition technique has given them added advantage over other contemporary competitors. This has also made them an economically feasible option. Since the inception of PSCs in 2009, a lot of improvements have been done in various aspects like composition, synthesis technique, fabrication method, and interface study. However, today it is crucial to think about the commercialization of PSCs. In this direction, the stability of PSCs has been a long-standing question. This review focuses on the key aspects of perovskite stability. Challenges posed by environmental factors like moisture, oxygen, temperature, and light are still unanswered. The lead toxicity of PSCs demands a potential substitute of lead with no compromise in their efficiency. The lead-free approach of PSCs and their commercialization has been discussed separately. A suitable emphasis has been given to the encapsulation of solar cells, as we find it a necessary part of the future commercialization process. This review has been addressed with an ideology to provide overall knowledge on the stability issues and challenges concerned with the PSCs, to attract young research community towards this emerging field. 2021 International Solar Energy Society

Influence of career re-entry enablers on job search outcomes: COVID strengthening the disparity virus?
subject: Career nreak; Career re-entry; COVID-19; Female workforce; SCCT model; Search outcome
description: Women in India when faced with the predicament of managing their homes and work, many a times are forced to take a break from their job. On completion of their personal responsibilities when they contemplate re-entering work, they face numerous hindrances. Covid has only raised additional concerns in their career landscape. In this context based on the social cognitive career theory that adopts human agency perspective we theorize that women are not mere bystanders but themselves contribute to their life outcomes through their self-efficacy and resultant job search efforts. Using the components in the SCCT model (Social cognitive career theory) of career self-management (CSM), data from 385 respondents was analysed using Exploratory Factor Analysis, Confirmatory Factor Analysis and Structure Equation Modeling. The study confirmed the direct and indirect relationship between self-efficacy in job search behaviour, outcome expectations, search goals, search actions and the final job search outcome measured through the number of offers received. Implications of this study to the managers, family and society are also discussed. 2021 Ecological Society of India. All rights reserved.

description: Withania somnifera is a herb of immense ethnopharmacological importance in Ayurvedic, Siddha and Unani systems of medicine. Due to its immense therapeutic potential and being an important source of novel withanolides, it has been a subject of immense intrigue among researchers. Apart from its anti-inflammatory, antitumor, anti-stress, antioxidant, immunomodulatory, antidiabetic, sedative and hemopoetic properties, there is mounting evidence for its antimicrobial and antiviral properties too. Various withanolides and steroidal lactones isolated so far are known to have high therapeutic value, but works pertaining to their antimicrobial potential have largely been at the synergistic level. No single withanolide has been characterized as a sole antimicrobial and thus, work in this regard is still in the stage of infancy, except for withanone which has recently shown in silico activity against SARS-COV-2. This review summarizes the elaborate antibacterial, antifungal, antiprotozoal and anti-viral work that has been done so far and casts focus on the limitations, in terms of mechanistic aspects of each. 2021 Society for Biology and Biotechnology.

The odd one is Out: Voices from virtual classrooms
description: This article is a response to the online classrooms initiated from April 2020 onwards in schools across the country after the declaration of the lockdown. As classes went live in some parts of the country and several schools prepped towards the new medium, voices and experiences emerged from the field to throw light on the odds. The article collects the voices of students, educators and parents largely from the cities of Delhi and Bengaluru. The narratives are to be seen against the background of the critique of auto-modernism and emergent technology-intensive social institutions in the wake of COVID-19. This perspective pieces together the issues of infrastructure inadequacy in technology and the exclusiveness of pedagogy, and charts the inability of the marginalised sections in exercising the fundamental right to education. This article also highlights that internet classrooms are temporary make-shift arrangements. 2021 Economic and Political Weekly. All rights reserved.

Recent advances in bimetallic based nanostructures: Synthesis and electrochemical sensing applications
subject: Bimetallic nanoparticles; Biomolecules; Detection limit; Electrochemical sensors; Sensitivity
description: Detection of biomolecules is paramount for the diagnosis of various health conditions in humans for improving the quality as well as the standard of living. Many of the existing analytical detection methods being used have one or the other drawbacks. This has led to revolutionary paradigms in research and development in the electrochemical sensing of biomolecules. Nanoparticles have enhanced surface area to volume ratio and are highly effective as sensors due to their improved electrocatalytic properties. Bimetallic nanoparticles such as platinum, nickel, iron, palladium, and gold-based nanoparticles in combination with other metals are being extensively used for electrode modification owing to their unique electrocatalytic characteristics. The synergistic effect of two metals provides us with highly sensitive electrodes. Over a while, there has been a significant increase in research carried out in this field, which encouraged us to carry out a thorough survey of the development of bimetallic nanoparticle-based electrochemical sensors for the sensing of glucose, hydrogen peroxide, ascorbic acid, dopamine, and uric acid. We have also mentioned the different types of electrode modifications for developing electrochemical sensors. This review provides readers a comparative study of the analytical parameters of the various electrochemical sensors for linear range, detection limit, and sensitivity. 2020 Elsevier B.V.

A critical review of anticancer properties of Withania somnifera (L.) Dunal with respect to the biochemical mechanisms of its phytochemical constituents
subject: Anti-cancer activity; Phytochemistry; Withaferin-A; Withania somnifera; Withanolide-A; Withanolides
description: Cancer is a leading cause of mortality worldwide, the conventional chemotherapeutic drugs have been known for their toxicity and numerous side effects. A new approach to treat cancer involves phytochemical drugs. In the present review, anti-cancer activity of a class of steroidal lactones called withanolides obtained from Withania somnifera (L.) Dunal is discussed. The commonly studied bioactive compounds namely withaferin-A, withanoside IV, withanoside VI and withanolide-A among others obtained from methanolic and chloroform extract of the leaves and various alcoholic, aqueous and chloroform extract of roots have shown inhibition to various human cancer cell lines including skin, breast, colon, prostate, liver, ovary, cervical and lung. Prominent mechanisms of action include induction of apoptosis by NOS upregulation, ROS production and NBS2 or COX-2 inhibition; cytotoxicity by humoral and cell mediated immune response, activation of p53 and pRB and inhibition of various viral oncoproteins; cell cycle arrest by Cdc2 facilitated mitotic catastrophe, cyclin-D1 down-regulation and inhibition of transcription factors. Cancers are also controlled by inhibition of angiogenesis and metastasis of the tumor cells. In addition to anti-tumorogenic properties, W. somnifera also holds properties that make it a potential adjuvant in integrated cancer therapeutics and in enhancing the effectiveness of ongoing radiation therapy.
