Modified Metal Organic Frameworks for Electrocatalytic Water Splitting and Energy Storage Applications
Metal-organic frameworks (MOFs) are a class of crystalline material formed by the newlinecombination of metal ions/clusters along with organic linkers. This work is mainly based on newlinesynthesizing MOFs and their application in electrocatalytic water splitting and newlinesupercapacitors. The MOFs synthesized in the present work are Ni-Cu, {Mn-NiNH2(h2fipbb)}, Mn-MOF/rGO, and Sm-MOF/rGO/PANI using different ditopic and tritopic linkers. Using various characterization techniques, the formation of the synthesized MOFs is confirmed. The increasing use of fossil fuels now contributes to a number of environmental problems, including climate change and global warming. High-performance electrochemical energy storage devices are essential for portable electronics, electric cars, newlineand renewable energy storage medium, driving demand. MOFs are emerged as a promising newlinecontender for energy storage applications owing to their novel microstructures, atomically dispersed metal centers, and earth-abundant metal components. Electrochemical water splitting is a crucial approach in the pursuit of producing environmentally friendly fuels such newlineas H2 and O2, reducing our dependence on traditional fossil fuels while promoting newlinesustainable and clean energy sources. In order to produce hydrogen with the best efficiency and lowest cost, these MOFs are used. Electrochemical studies like cyclic voltammetry, galvanostatic charge discharge, and electrochemical impedance spectroscopy reveal that the prepared MOFs can be used as supercapacitors. Linear sweep voltammetry and Tafel plot determine the performance of these MOFs towards water splitting studies. Supercapacitors, which are electrochemical capacitors, are popular energy storage devices with quick charge rate, high power density, excellent rate capability, and outstanding life expectancy.
Thinking Beyond Empowerment : Understanding Autonomy in the Context of Kudumbashree
The concepts empowerment, agency and autonomy have gained a wider range of attention in newlinethe developmental research regimes. Amidst the conceptual drift these concepts are used newlineinterchangeably leading to uncertainty and proliferated meanings. The process of newlineempowerment may not always lead to autonomy. Through an ethnography of Kudumbashree, newlinean SHG in the South Indian state of Kerala, the current research focuses on how these women exercise agency to trouble the conventional boundaries between empowerment and autonomy. The transition of agency from the economic to the political domain is a subtle enterprise and is mediated by a number of factors including economic independence, decision making capability, mobility and political participation. Social - economic - political and cultural implications of women empowerment could be the first step in challenging and overcoming the relations of oppression in any society. The stereotypical assumptions can be negotiated by solely apportioning responsibilities and re-engaging with the system through everyday practices. The nuances of empowered women s re-engagement with local power regimes lead newlineto changes at the conceptual level that cuts beyond the individual and group level material transformations. The study figures how autonomy is a mediated process that is both agentic and subversive to the local patriarchal structures.
A Critical Study in ADR Mechanism in India with Reference to Court Annexed Mediation in Family Disputes
Mediation has been in vogue in India since time immemorial. Sadly, it is yet to evolve into a major dispute resolution mechanism. Alternative dispute resolution (ADR) mechanisms like arbitration, mediation, conciliation, courtannexed ADR, and summary jury trial would help in resolving all types of disputes, including those of a civil, commercial, industrial and family nature. newlineGenerally, ADR mechanisms would use a neutral third party that help the parties to communicate, discuss their differences and resolve the dispute. With matrimonial dispute numbers rising and the significance attaching to matrimonial bond in our country, the researcher set out to examine the country s court-annexed mediation mechanism to ascertain how the flaws, if any, that obtain in the mechanism can be addressed. It should lead the researcher to recommend a strategy for a seamless and hassle-free implementation of the relevant regulatory provisions. The researcher embarked on descriptive research, employing the survey method, in the newlinecircumstances. She collected data from primary and secondary sources for the newlinepurpose. The ensure bias minimisation and accuracy of findings, she interviewed two categories of respondents, namely, litigants numbering 100 and mediators numbering 100. She used a 4-point Likert scale to elicit the newlinerespondents replies to the queries raised in the Interview Schedule. Since the two variables used in the study were categorical and nonordinal, she used the Chi-square test to examine the relationship. The researcher s analysis of the data led her to conclude that there obtains a certain degree of lack of clarity in terms of the enforceability of the outcomes of mediation. For example, in court-annexed mediation, a settlement reached newlineby the parties is not enforceable automatically. It is unfortunately assumed in newlineour country that mediation is resorted to by litigants who do not have a strong newlinecase. It is also assumed that the litigant that chooses mediation is the one that newlineblinks first.
Corporate Insolvency Resolution Process Under Insolvency and Bankruptcy : A Critical Study
A robust legal system is essential for corporations to carry on business smoothly. Previously in India, winding up and corporate rescue were dealt in multiple legislations for different entities. Provisions relating to winding up of companies were found in The Indian Companies Act 1913, Indian Companies Act, 1956 and further in the Companies Act, 2013. These provisions did not ensure expeditious winding up procedures and the same affected the interest of stakeholders. newlineThe increase in NPA compelled the need to bring an efficient framework to protect the rights of creditors and debtors. As a solution to this IBC was enacted in 2016, to facilitate timely resolution of insolvency and bankruptcy. This research aims to critically analyze the provisions of corporate insolvency resolution process, to examine whether IBC is facilitating newlinerehabilitation of insolvent corporations and protecting the interest of creditors, so as to balance their interests. It further aims to outline a draft policy for a better insolvency resolution process in India. Primary data for the study was collected through a structured interview of stakeholders and conclusion was drawn through a qualitative thematic analysis using NVivo software. The findings showed that, through CIRP there is debt recovery for financial creditors, but it is not expeditious. There are multiple reasons for the delay. The operational creditors are not able to newlinerecover from the process and as a result, many of them are turning insolvent. The rights of the corporate debtor are protected under the Code but they are not adequately protected under the Code as there is no value maximization under the Code. There are many delays in the process, resulting in more companies going into liquidation. IBC is a debtor friendly legislation. Both resolution and liquidation benefit the corporate debtor as it helps the company to resolve its newlineinsolvency.
School Counseling in India : School Counselor Roles, Policy and Implementation
With a lack of comprehensive policy and literature on stakeholders perspectives and the counseling program s implementation, there is much to be known about the present status of school counseling in India. Three research questions examined in two phases were the perception of actual and preferred roles of the school counselors from the perspective of school administrators, school counselors, teachers, students, and parents; awareness and implementation of school counseling policy from the perspective of administrator and counselors; and implementation of the school counseling program. Quantitative phase I met newlineobjectives one and two using cluster sampling to select 1029 participants. School newlineadministrators and counselors completed the Survey on Knowledge and Implementation of newlinePolicies Regarding School Counseling which was developed and validated by two experts in newlinethe study. All participants completed the International Survey of School Counselor Activities (ISSCA) (Fan et al., 2018). Statistical analysis included descriptive statistics, the KruskalWallis H test, and post-hoc Bonferroni-Dunn. Qualitative phase II met objective three using purposive sampling to recruit 14 participants for a semi-structured interview. Qualitative newlinecontent analysis indicated that school counseling in India is still developing, with newlineinconsistencies in understanding the counselor s role among stakeholders. There were differences in awareness and knowledge about the responsibility of implementing school counseling policies. School counseling programs were affected by role ambiguity, stigma about mental health issues, lack of comprehensive structure to the counseling program, and lack of research and evaluation. Implications of the study are discussed.
On the Maximization of Some Graph Coloring Problems
A graph coloring problem involves labeling the vertices or edges in a graph with newlinecolors or numbers subject to some constraints. The most frequently known graph newlinecoloring problems are the ones that usually minimize the number of colors used in newlinecoloring the vertices or edges. The chromatic number of a graph G, denoted by and#967;(G), is the least number of colors used in a proper coloring of G. The chromatic sum of a graph G, denoted as P(G), was introduced in [1], which is to and the smallest possible coloring sum in a proper coloring of the graph G using natural numbers. Lately, a few studies have endured in a distinct area of the literature where the number of colors used in a graph coloring problem is maximized under certain conditions. Some of these works have applications in network sciences. newlineThe concerned study focuses on the maximization of three dierent edge coloring newlineconcepts, viz., the vertex induced kand#8722;edge coloring, vertex incident kand#8722;edge coloring, newlineand edge incident 2and#8722;edge coloring of a simple connected graph G, where k and#8805; 2. The newlinenumber of colors assigned to the edges of the graph G has been maximized under certain conditions. The vertex induced kand#8722;edge coloring and the vertex incident newlinekand#8722;edge coloring concepts are the generalized version of the edge coloring approach newlineintroduced and studied in [2]. Furthermore, the concept of the achromatic sum of a graph G has also been introduced here. This concept is to and the greatest possible coloring sum of the graph G in an improper edge coloring using natural numbers. An extensive study newlineon three achromatic sums, namely the vertex induced 2and#8722;edge coloring sum, the vertex incident 2and#8722;edge coloring sum, and the edge incident 2and#8722;edge coloring sum are carried out. A few bounds for these parameters on a simple connected graph G and the exact values for some elementary graph classes have been investigated. A few comparative results between some of these parameters have also been obtained.
Synthesis, Process Parameter Control and Performance of Nano Ceramic Coatings for Diesel Engine Applications
Ceramics are non-metallic inorganic solids which are used in various forms (bulk and newlinecoatings) and environments (low and high temperature) to provide protection from newlinethermal, wear or chemical attack. Due to their high melting point, compressive newlinestrength, oxidation and corrosion resistant properties, ceramics are strong, hard, newlinebrittle and harsh environment resistant. Ceramic coatings are generally applied on newlinemetal components to either enhance their life or augment the performance of the devices they are mounted on. Furthermore, coatings being thin (few small units to hundreds of microns); they do not demand significant alteration in component design. Among the many types of coatings used in engineering applications, Thermal Barrier Coatings (TBC) and wear resistant coatings (WRC) are used to protect metallic components from thermal and mechanical damages respectively. 6 to 8%Yttria stabilized zirconia (6-8% Y2O3-ZrO2), generally designated as 8YSZ has been newlineextensively used as TBC and alpha alumina (and#945;-Al2O3) find applications as WRC. 250 to 300m thick micron grained TBC, with grain sizes typically up to 20 m or even higher are well known to thermally insulate diesel engine combustion chamber to provide enhanced fuel efficiency characteristics. 8YSZ and and#945;-Al2O3 coatings also find use in power plants, textiles, automotive and aero-space industries etc. to provide benefits like improved product quality and energy efficiency, extended wear life, reduced maintenance cycles and costs etc. Among ceramic coatings, nanostructured coatings have received further interest because of their extraordinary properties including enhanced hardness, strength, ductility, and toughness when compared with coatings with micron grained newlinemicrostructure. Nanostructured zirconia is also expected to serve as advanced TBC in newlineengine applications, although information on its feasibility and the technology is mostly classified.
Algorithmic and Non-Algorithmic Trading Activity in the BSE Using Limit Order Book of Select Stocks
With the existence of a heterogeneous market compounded by asymmetric information, technology has become one of the major newlineenablers in stock market development. Introduction of algorithms for trading gave a fillip to many stock market participants and allowed them to trade rapidly and profitably. In the present day in Indian stock market, newlinewe have two types of market players; algorithmic traders and nonalgorithmic traders. The algorithmic traders are playing a dominant role in order placement, order modification and order execution while the newlinenon-algorithmic traders still continue to use their intuition. This study aims to understand the trading activity of both the market participants. The study uses the Limit Order Book data from Bombay Stock Exchange. newlineThe LOB data of selected nine stocks is considered for the study whose variables namely Order Added, Order Updated and Order Deleted data along with the Bid Ask Quotes are considered for measurement. Based on newlinethe Limit Orders it is observed that there is a statistically significant difference in the trading behavior of algorithmic and non-algorithmic traders based on stock market session timings and market capitalization. newlineThe market making ability of the algorithmic traders was examined using Order-to trade Ratio and it is observed that large number of orders are not executed indicating that there is no significant Market Making happening. newlineThe algorithmic traders possess an edge over the non-algorithmic traders in Order Modification resulting in dominance in the Stock market. The Mann Kendal Trend test indicates upward and downward trend in newlinevolume adjusted spread indicating that market making is happening especially in the stocks where algorithmic activity is high. This study enables regulatory authorities to monitor stock market activity especially during pre- open session. This study provides sufficient scope for further research on future of algorithmic trading activity and its ramifications on non-algorithmic trading activity in the future.
Animal-Assisted Therapy : Effect on Neuropsychological Functioning, Depression and Emotion Regulation
The mere presence of a dog in a therapeutic setup is known to bring about positive newlineoutcomes, so when incorporated into therapy, dogs can bring multifarious benefits that are not entirely tapped upon. There also exist cultural differences in the perception towards and acceptance of animals which limits the generalisability of western literature. This research aimed to study the effect of animal-assisted therapy, with therapy dogs, on depression, emotional newlineregulation and neuropsychological functioning of individuals. A pretest-posttest experimental research design was used wherein 42 participants were matched and randomly divided into experimental and control groups. Both the groups received therapeutic interventions once a week, for 45 minutes, over a period of 2 months, however, only the experimental group received animal-assisted therapy. Beck Depression Inventory-II, Difficulties in Emotion Regulation Scale newlineand NIMHANS Neuropsychology Battery were used to gauge the level of depression, emotion newlineregulation and neuropsychological functioning before and after the intervention. The findings reveal that both the experimental and control group saw a significant improvement in their level of depression and emotion regulation, however, only the experimental group showed a significant improvement in all the measured domains of neuropsychological functioning. No newlinesignificant changes were observed in the domains of neuropsychological functioning of the control group. The results help validate the animal-assisted therapy interventions provided to improve the individuals neuropsychological functioning, and emotion regulation and alleviate depression. Further implications are identified and discussed as per the results.
A sum signed graph S = (G, f, and#963;) is a signed graph of the underlying graph G where f : V (G) and#8722;and#8594; {1, 2, . . . , | V (G) |} is a bijective function and and#963; : E(G) and#8722;and#8594; {+, and#8722;} is newlinea mapping such that and#963;(uv) = +, whenever f(u) + f(v) and#8804; n and and#963;(uv) = and#8722;, whenever f(u) + f(v) gt n. The minimum number of negative and positive edges among all the sum signed labelings of G is known as rna and rna complement number respectively. The maximum number of positive edges among all the sum signed labelings of G is known as adhika number. The set X and#8838; V (G) is said to be a s - dominating of a signed graph whenever X is a dominating set and there exists exactly s number of negative edges between X and its complement. The minimum cardinality of such a dominating set over all signed graphs of the graph G is called an s - domination number. newlineIn the present study, we initiate the study of a new labeling in signed graphs namely, newlinesum signed labeling. The characteristics of sum signed graphs and the bound of rna number of in terms of the number of vertices in the underlying graph are explored by examining the rna number of different graphs. The properties of signed graphs such as negating and balancing is analyzed. The relation between rna number and rna complement number is established. The connection of sum signed labeling with parity signed labeling and cordial labeling is discussed. The absolute cordial condition for graphs satisfying sum signed labeling is examined. The concept of s - domination was also introduced during this period of study. The s domination in both the positive and negative homogeneous signed graph is investigated for each value of s. The properties of s domination in sum signed graphs are also analyzed. The s - domination number for specifc values of s is investigated for various graphs. The maximum value of s for a graph for which the s - domination will exist is discussed.
Modification of Carbon Based Electrodes as Robust Scaffolds for Electrochemical Sensing of Vitamins and Hormones
Electrochemical sensors are for vitamins and hormones are constructed on employing various newlinemodifications (molecular imprinting technology, coating of 2D sheet like materials and also modifying using supramolecular complexing material) on the transducer host, carbon fiber paper electrode (CFP). From our observation, the electrochemical oxidation/reduction current newlineof the analytes studied, intensified significantly on the surface modifications employed over the CFP substrate. Surface morphology was characterized using Field Emission Scanning Electron Microscopy (FESEM), Electron Diffraction X-ray (EDX), X-Ray Photoelectron spectroscopy (XPS), Optical Profilometry and Fourier Transform Infrared Spectroscopy (FTIR). Nyquist plots revealed the least charge transfer resistance at the finally modified working electrodes compared to other control electrodes. Optimization of experimental conditions such as effect of pH, investigating the reaction mechanism via effect of scan rate, number of cycles for the electrodeposition of the film in order to achieve maximum current response and potential window were studied in detail by using cyclic voltammetry (CV). Quantification of the analytes was performed using Differential Pulse Voltammetry (DPV). newlineAnalytical corroboration for real samples were carried out using the finally modified newlineelectrode. Therefore, all the works carried out have established simplicity and selectivity in the principle of the novel approach in the development of an ultrasensitive voltammetric sensor for vitamins and hormones studied.
Antecedents of Psychological Capital and Its Consequences on Affective Commitment and Psychological Wellbeing
Jharkhand Education Board stakeholders face the problem of dealing with the educational environment, thereby escalating a teacher's morale. To address this situation, a positive mindset in education, particularly among teachers, is desirable. Hence, based on positive psychology discipline resource theory conservation, and broaden and build theory, the study was carried out using a sequential explanatory mixed-method study design. The research questions addressed in the study were as follows: To what extent can the categories of proactive personality, emotional intelligence, servant leadership, and perceived organizational support predict PsyCap of teachers? To what extent will PsyCap predict the categories of affective commitment and psychological wellbeing? We considered both quantitative and qualitative methods; hence, this study had two phases. In the first phase, the data was gathered from 900 teachers using the survey instruments. The statistical analyses performed were Confirmatory Factor Analysis and Structural Equation Modeling with the software SPSS 20.0 and AMOS 20.0. For teachers of rural Jharkhand, the study found that psychological capital has three dimensions. Besides proactive personality, emotional intelligence, and servant leadership also impact psychological capital. Further, psychological capital affects affective commitment and psychological wellbeing. In the second phase, this study examined the way and the reason behind the functioning of the antecedents of psychological capital using qualitative content analysis. The results offered a comprehensive understanding and identification of the antecedents that form rural teachers' psychological capital. Implications of the research include recommendations for recruiting teachers with higher levels of psychological capital and professional development through in-service teachers' training with a specific focus on psychological capital.
Admissibility of DNA Profiling Evidence in Criminal Trials in In India : A Comparative Study with Specific Reference to Legal Systems of United States of America and England
The use of Forensic technique of DNA profiling now constitutes a standard element of the system of Law Enforcement, and the findings of DNA testing are often acceptable in the proceedings of Legal cases. Despite newlinethe fact that they first relied on Expert Testimony based on DNA Evidence, the Courts in India have come to acknowledge DNA Evidence as both a fact that is significant to the case as well as proof that is conclusive. On the other hand, the scope of guilt that is capable of being concluded from a seeming match between samples is a topic of on-going debate. In most cases, it will newlinemerely be capable to locate the position of a suspect in relation to the site of the Crime. The uncritical acceptance of this Forensic Evidence as the objective answer to the challenge of determining the identity of a criminal raises the potential for scientific appropriation of the Criminal Justice system. newlineIn the vast majority of contested Legal proceedings involving Criminal offenses, the issue at hand is not one of identification but rather one of Intent or Mens-Rea, and DNA Evidence is irrelevant in this regard. Additionally, it is imperative to create a Regulatory framework which controls how the newlineForensic technique of DNA Profiling is used and applied with the objective to ensure its methodical and organized implementation. In light of this, it is very important to make rules about DNA Profiling that will only allow it to be used for Legal investigations. In an effort to regulate DNA profiling in the newlinecountry, the DNA Technology (Use and Application) Regulation Bill 2019 has been proposed. The emphasis of this study, is the particular difficulties experienced by the Indian Judicial system as a consequence of introducing this novel Forensic technique into the Criminal Proceedings, and the research aims to examine the evolution and use of DNA profiling in India.
Development of Family Intervention for Management of Psychogenic Seizures : A Qualitative Study
Background: In the somatoform and dissociative spectrum, family functioning has been poorly researched based on the search in PubMed, Google Scholar, Science Direct, PROQUEST, EBSCO and Cochrane Reviews. In Psychogenic Non-Epileptic Seizures (PNES) primarily, family functioning has been understood as a comparison between Epileptic Seizures (ES) and PNES. However, an attempt to study different aspects of family functioning and its ability to influence the newlinemanifestation of the disorder is yet to be made. Methods: This study attempted to understand different family functions qualitatively by interviewing both the patients and family members of these patients. Nine patients and seven families of these patients participated in the study. Braun and Clarke s thematic model was used. Latent thematic analysis was used to analyse the data. Based on the analysis, major and sub-themes were used to develop family intervention and a family psychoeducational model. Both were developed with the help of the GUIDED Checklist to report health interventions; the TIDieR format and Delphi newlinetechnique was used to collect the expert opinion of the developed intervention. newlineResults: Two sets of results and analyses were compiled with qualitative data, that is, for patients and families. Major themes and sub-themes were developed for both, including family interaction, attachment, poor communication, structural-systemic aspects, distressful family aspects, negative newlineexpressed emotions, cultural aspects, nature of the illness, family s views of the illness and coping mechanisms. These themes indicated the importance of family functioning and its impact on the manifestation of the disorder. newlineConclusion: The researcher concludes that family dysfunction can impact the manifestation of the disorder. Hence, an additional family intervention or psychoeducation is essential for holistic newlinetreatment.
Role of Green Human Resource Management Practices on Sustainable Performance of the Service Sector Organizations
The prominence revolution took place in the 1980s, and then the Green HRM practises movement blew over the sustainable development literature in the 1990s. This represents an excellent practice because it newlineincorporates sustainable development principles into the operational processes newlineof the human resources department. According to Mishra (2017), Green HRM is a tactical instrument for arranging human resource competences and promoting ideas that motivate businesses to embrace sustainable strategies. newlineThe term human resource management (HRM) is used to describe a set of practices, procedures, and methods that are focused on managing and optimizing the performance of personnel within a business, thereby providing the organization with a competitive advantage. Despite the fact that green human resource management has grown to be a major source of concern, India has only relatively handful of first-hand studies done in this area. While conventional HRM concentrates on functions to provide an organisation a competitive edge, green HRM places an emphasis on the capture and retention of green efforts to meet corporate objectives. newlineGreen HRM in India is plagued by a variety of issues. The study has chosen a few traits from the research at hand that may be utilised to create Green HRM practices for sustainable development. It stands to reason for contemporary businesses to take environmental responsibility seriously (Jackson, Renwick, Jabbour and Camen, 2011). Numerous studies show that environmental newlineinitiatives increase production and provide companies a competitive edge (Bombiak and Marciniuk-Kluska, 2018). Although organizational solutions quotmoved beyond pollution control and the mitigation of environmental degradationquot, Saeed, Jun, Nubuor, Priyankara and Jayasuriya (2018) have highlighted its significance in the New Millennium Era.
A topology on a set is a collection of its subsets, including the set itself and the empty set, which is closed under union and fnite intersections. This dissertation introduces the notions such as graph topology, spanning graph topology, generalised graph topology, and generalised spanning graph topology by considering subgraphs and spanning subgraphs of a graph. Analogous to the set-theoretic notion, a graph topology is a collection of subgraphs of a given graph, including the null graph K0 and the graph itself, that is closed under newlineany union and any intersection. At the same time, a spanning graph topology of a graph is a collection of spanning subgraphs, including the spanning empty graph Nn, where n is the order of the graph and the graph G, which is closed under any union and any intersection. The topological concepts such as open sets, closed sets, base, subbase, neighbourhood, interior, subspace, and connectedness of spaces are extended to graph topology and spanning graph topology. In order to study the closed graphs in the above-mentioned graph topologies, two new graph complements are introduced in these graph topologies, such as decomposition and neighbourhood complements, to defne decomposition closed newlineand neighbourhood closed graphs. The decomposition complement is defned with respect to the edge set and the neighbourhood complement with respect to the vertex set. Since all the members of a spanning graph topology have the same vertex set, the neighbourhood closed graphs are described in terms of the edge set. The notion and characteristics of subspaces of both these graph topologies are defned, and the properties of closed graphs in these subspaces are also studied. Connectedness in topology holds a prominent role and applications in various felds of mathematics. The idea of connectedness is extended newlineto these graph topologies, and the same is characterised in the context of graph newlinetopology.
Green Synthesis of Nanoparticles Leading to the Biocontrol of Aedes Aegypti
Mosquitoes are the potential vectors of many diseases such as malaria, dengue, brain newlinefever, etc. There is a need to check the proliferation of the population of vector newlinemosquitoes to reduce vector-borne diseases by appropriate control methods. Nanotechnology, a promising field of research, opens up in the present decade and is expected to give major impulses to technical innovations. Over the past few decades, nanoparticles of noble metals such as silver exhibited significantly distinct physical, chemical and biological properties. Presently, there is a need for increased efforts to develop newer and more effective methods to control mosquito vectors. Due to different technical and operational reasons, the existing chemical and biological methods are not as effective as in the earlier period. Therefore, this study is designed to extract silver newlinenanoparticles from plant, fungal and bacterial species and assess their impact on the third and fourth-instar mosquito larvae and the adult mosquito (Aedes spp). The study has formulated a gel material that is composed of nanomaterials that exhibited promising properties to develop a nano gel product. The study is designed in a way to have an impact on the control of mosquito larvae using biologically synthesized nanoparticle formulations. Green synthesis is expected to show a higher yield of nano products that can be formulated in various forms to standardize the biocontrol of mosquito species. Bioinformatic studies revealed the good binding potential of the extracted bio compounds against the juvenile hormone binding proteins in A. aegypti. The study deduced meaningful outcomes that can benefit the environment by controlling the mosquito population and thereby reducing disease transmission in many developing countries.
Topological Indices Based on Distance Labeling
This thesis explores the prospect of combining two prime branches of graph theory, newlineviz., topological indices and graph labeling, specifcally radio labeling. The majority newlineof the work includes the topological radio indices of graphs and their properties. Topological indices are numerical values associated with graphs and invariant with graph isomorphisms. Apart from Topological Radio Indices, it provides some additions to the eccentricity-based topological indices. newlineRadio labeling or radio coloring, c, is assigned to a graph G such that the label difference between any two vertices must be greater than diam(G)+ 1 and#8722; d(u,v). Optimum radio labeling is the foundation for defning Topological radio indices. Labeling whose span is the radio number of the graph and which leads to the minimum value of the index newlineis considered the optimum radio labeling. The topological radio indices and coindices newlineare defned and are found out for some special classes of graphs, including gear graphs, newlinewheel graphs, and star graphs. The bounds for the frst, second and third Zagreb radio indices have been established and characterized for the classes of graphs for which the bound is sharp. Furthermore, newlinespecifc relationships between Zagreb radio indices and coindices are established concerning different parameters of the graph. newlineThe idea of consecutive radio labeling is explicitly studied. We have characterized the newlinegraphs with diameter 2 admitting consecutive radio labeling. We have studied the properties of graphs admitting consecutive radio labeling and stated the necessary and suffcient conditions for a graph to follow consecutive radio labeling. The study extended to eccentricity-based topological indices, viz., the forgotten eccentricity indices. The maximum d(u,v) for all v in V(G) is the eccentricity of the vertex u in G. This work also investigates eccentricity-based coindices and some of their properties. newlineApart from this, some uniquely radio colorable graphs are examined and characterized.
Perceived Morbidity, Health Seeking Behaviour and Healthcare Utilisation among Inter-State Women Migrant Workers in Kerala
Internal migrants in India are estimated to be 37% of the total population with Kerala estimated to host over 25 lakhs of internal migrants. Migration, both internal and international can influence a country or region s socio-economic development. The interrelation between health and migration is highlighted in the Sustainable Development Goals where health is determined as an indicator of people-centred, rights-based, inclusive, and equitable development . Though migrants as such are a vulnerable population, the gender experience of migration differs, as women migrants often face triple discrimination of being a woman, unprotected worker and a migrant making them the most vulnerable within the migrant community. They are often overlooked while formulating schemes and policies depriving them of health and social security benefits. The present newlinestudy aims to understand the perceived morbidity, health seeking behaviours and healthcare utilization among Interstate Women Migrant Workers in Kerala. The sequential exploratory research design was employed to newlinecollect data from workers in the seafood processing and textile manufacturing sectors. The qualitative phase had two focus group discussions with 8 participants each and four in-depth interviews while the quantitative newlinephase had cross-sectional surveys with 300 respondents. The focus group discussion and in-depth interview paved the way for understanding the issues and concerns of the respondents regarding their health seeking newlinebehaviours and healthcare utilization as well as hinting at their attitude towards health in general. Themes were able to provide insight into the factors underlying healthcare utilization as well as provided suggestions from the respondents which could have policy implications. The quantitative data was elaborate and was able to address the various dimensions of health seeking and determine the factors influencing healthcare utilization among interstate women migrants in Kerala.
Prevention of Child Sexual Abuse : A Protection Motivation Theory-Based Intervention for Mothers of Preadolescents
Child sexual abuse (CSA) is a growing concern in the world. Prevention of CSA in India is challenging due to deep rooted traditional values and beliefs. Sex and related matters newlineare difficult topics for parents to discuss. Lack of parental awareness leads to increased newlinerisk for CSA. Maternal care is the most influential aspect of child rearing and they need information and skills to educate children on sexual abuse. The literature review was based on Bloom s taxonomy for academic writing. The need for systematic and evidencebased approach in primary prevention was identified. The aim of this study was to test the efficacy of Protection Motivation Theory (PMT)-based psycho education program in enhancing mothers knowledge, attitude and sense of parental competence among mothers. An interactive mixed-method design embedding quantitative and qualitative methods selected 72 mothers as participants from Kannur, Kerala. Mothers aged between 30-40 years who had preadolescent children (8-12 years) were assigned to control and experimental group. A facilitator s psycho education manual was developed embedding PMT constructs for the intervention. The quantitative results indicated significant differences between the groups for CSA knowledge and attitude. The impact of the intervention was moderate to high. The qualitative results indicated the benefits of intervention. Mothers have overcome communication blocks, misconceptions regarding CSA education are cleared, are aware of risks and warning signs and are confident to deal with CSA disclosure. The involvement of mothers in the prevention program was found to be effective in this study. The findings of this study have important implications for developing theory- based interventions for CSA prevention. The application of systematic evidence-based interventions promotes active engagement of participants for applying the learnt skills effectively. The culturally sensitive issues like CSA needs more contextual understanding of the problems to find effective solutions.
