Selective Oxidation of Hetrocyclic Alcohols Using Carbon Based Modified Electrodes
Electro-organic synthesis has achieved great significance over the conventional synthesis routes due to its diverse features which includes the in-situ generation of reagents, replacement of harmful redox reagents, rapid response, and low energy consumption. The choice of reactants (heterocyclic alcohols) for the electrochemical oxidation is solely based on the applications of its corresponding aldehydes. Furthermore, 2-thiophene methanol, piperonyl alcohol, 5-methyl furfuryl alcohol and Tetrahydro furfuryl alcohol have been chosen as reactants of interest as their corresponding aldehydes 2-thiophene carboxaldehyde, piperonal, 5-methyl furfural and Tetrahydro furfural possess various synthetic applications such as production of newlinedyestuffs, perfumes, veterinary products, agrochemicals and pharmaceutical drugs. newlineCarbon based electrodes provide a versatile platform for catalysis reactions. newlineElectrocatalysts for the selective oxidation of heterocyclic alcohols are designed on newlineemploying diverse modifications on the carbon fiber paper (CFP) electrode. Such newlinemodifications have attracted researchers due to their exceptional selectivity, stability, newlineelectrical conductivity and lower charge transfer resistance. The modifications newlineemployed in the current study include immobilized laccase-based materials and newlinegraphitic carbon nitride-based composites. newlineThe physico-chemical properties of the fabricated electrodes were studied using newlinedifferent characterization techniques like Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-ray Spectrometry (EDS), X-Ray Photoelectron spectroscopy (XPS), Optical Profilometry (OP) and Fourier Transform Infrared Spectroscopy (FTIR). Electrochemical investigations were performed using Cyclic Voltammetry (CV), Chronoamperometry (CA) and Electrochemical Impedance Spectroscopy (EIS).

Smart beta investing in India portfolio construction implementation and evaluation
The smart beta strategies, having marked their footprint in the developed markets in the last decades on the backdrop of the failure of active investing, are capturing emerging markets such as India recently. In this regard, the study attempts to examine the performance of smart beta strategies in long-only, multifactor, and alternative indexing frameworks in India. The study builds alternatively weighted (AW) univariate portfolios. Firstly, the cap-weighted (CW) single-factor portfolios are built. Subsequently, the portfolios are alternatively weighted and compared to the CW portfolio. Next, the CW multifactor portfolios are built and compared with singlefactor portfolios. Finally, the AW multifactor portfolios are built and newlinecompared with CW multifactor portfolios. All the portfolios are tested for their significant performance relative to the risk-free rate, market, and alpha under factor models. The portfolios were constructed from the constituents of NIFTY 500, adjusting for survivorship bias. The sample period spanned over 21 years from 01/10/2000 to 31/09/2021. The hypotheses were tested using the One-Sample T-test or Wilcoxon Signed Rank test for the difference in return, based on return distribution, and the Wald test for the difference in alpha and exposure using the Seemingly Unrelated Regression framework. The portfolios were constructed and analyzed using Python. We find mixed evidence of factor presence; the factor portfolios built on market data such as Illiquid, Winner, Stable, and Size offered better performance than those built on fundamental data such as Value, Strong, and Conservative. The Integrated portfolio does not differ from Mixed and single-factor portfolios, except for underperformance against the Illiquid portfolio. The alternative weighting offered mixed performance at single and multifactor levels. -

Isolation, Identification and Characterization of A Potential Probiotic Bacteria and its Application in Aquaculture
In the current study, Bacillus subtilis PKB1 was isolated from dried anchovies and identified using morphological and biochemical analysis followed by 16S rRNA sequencing and phylogenetic analysis. The antibacterial and anti- haemolytic properties of the bacteria were also examined. Probiotic qualities were assessed by measuring the isolated strain's tolerance to artificial gastric juice. To assess the isolated strain's capacity for stress tolerance, additional exposure to varied pH, temperature, and organic solvent concentrations was given. Bacillus subtilis in MRS medium produced exopolysaccharide (EPS) which was purified and a maximum yield of 1928mg/L was achieved. The novel exopolysaccharide was purified and characterized to be a heteropolysaccharide. The polysaccharide present had a molecular weight of about 20 kDa overall. FTIR spectroscopy revealed the presence of carboxyl, hydroxyl, and methylene groups in the EPS. The extremely cross-linked structure of the EPS with lumps that resembled spikes was revealed by atomic force microscopy. Scanning Electron Microscopy (SEM) revealed that it possessed rough, asymmetrical lumps. Emulsification activity was also observed in the EPS. The current study's findings suggested that this EPS might make a good candidate for further applications. Utilizing probiotics derived from unconventional sources may improve the variety of probiotics accessible for use in aquaculture procedures. Probiotics are used in the field of aquaculture in order to improve immunity and to protect against pathogenic microbes. Species such as Aeromonas hydrophila and Vibrio parahaemolyticus are responsible for increasing mortality, decreasing production efficiency and forcing antibiotic overuse. In this study, the role of the isolated probiotic in promoting growth performance in Nile tilapia was examined using growth and challenge studies. The experiment was conducted for a duration of 30 days. Weight gain, histology and mortality rates were studied in the presence and absence of pathogenic microbes. Bacillus subtillis PKB1 supplementation for Nile tilapia helped to maintain the integrity of gill filaments and improved survivability and weight gain when used at a concentration of 1x104 CFU/ml. The study showed that the isolate improved the survival rate of Nile Tilapia against Vibrio parahaemolyticus and Aeromonas hydrophila. -

Legal Aid Education in Karnataka: A Critical Analysis
Legal Education has witnessed major transformations since the last few decades. The Constitutional ideals of justice, have been the foundational philosophy of legal newlineeducation in India. Consequently, legal aid has been a crucial link in the entire gamut newlineof advancing the values of justice. However, these purposes and ideals have undergone newlinemutations over the years. Aligned to these ideals, the Bar Council of India, had newlineintroduced legal aid as an important pedagogic tool that can fulfil twin mandate of providing justice to the common man and at the same time, train the students of law in newlinethe necessary skills and imbibe values in their journey of professional and social newlinecommitments. The history of legal aid is not new, in India and in the global context, yet legal aid as an educational tool is undermined and least prioritized in institutions that impart legal education. This could be attributed to various reasons, priorities of the institutions, ambiguity in understanding and working towards these goals. With the emergence of National Law Universities and various types of institutions on one hand and the newlineproportional rise in the number of students pursuing legal education on the other hand, newlinecreates a vast arena for the institutions to augment the existing resources in contributing to the societal needs. There have been various studies that have been conducted which focus on certain newlineaspects of law school clinics, specifically in creating Access to Justice. But there have newlinebeen limited studies in considering legal aid as an educational tool in terms of Teaching, newlineLearning and Research. There has been lack of evidence based approach that are employed to understand impending issues that hamper the effective working of legal aid within an institutional set-up. Hence the current study focuses on how the internal and external pressures act on legal aid within four different types of institutions across the state of Karnataka. -
Attitude and perception of tourists in Karnataka towards Climate Change
Climate change has a strong relationship with the tourism industry. According to the United Nation's World Tourism Organization???s Davos Declaration (2007) tourism industry contributes on an average about 5% of the global Carbon di Oxide emission in terms of radioactive forcing. Studies pertaining to the state of Karnataka, India indicate that most parts of the state could experience 1.5oC to 2oC warming relative to the level during the pre-industrial period of the 1880s by as early as 2030s under the likely high emission scenario (Kelkar et al, 2004; Dwarakish et al, 2009'; Kumar et al, 2015). Travel decisions to a large extent are influenced by the destination???s images of Sun, Sand, Sea, availability of snow and perceptions of other such climatic variables such as temperature, precipitation and humidity (De Freitas, 2001). Therefore, studying tourist???s perceptions of these environmental changes are crucial for the survival of the tourism industry especially in these climate-sensitive regions (Gossling & Hall, 2006a). Besides, understanding the attitudes and perceptions of different segments of the tourists towards their role in climate change adaptation and mitigation is a fundamental step in designing educational and communication campaigns which could be successfully implemented in this industry (Becken, 2010; Gossling & Hall, 2006; Saarinen et al, 2006; Scott et al, 2008; Martin & Lopez, 2014). Therefore, this study aims to boost our understanding of the relationship between tourism and climate change issues among tourists in Karnataka, India. The study consists of five chapters, namely Introduction, Review of Literature, Report on present investigation, Results and Discussion, Summary and Conclusion. The first chapter Introduces the relationship between tourism and climate change issues and brings out the significance of the role of travel decisions the environment. The second chapter analyses earlier studies conducted on the area of climate change, environment and tourism to gain a better understanding of the existing knowledge and to identify research gaps. The third chapter focuses on the research design of this study. It covers sampling plans, questionnaire design, constructs measurement, plan of analysis and Pilot study. The fourth chapter deals with the analysis of data which were collected for the study followed by the discussion of results.

Paired curves on riemannian manifolds
The thesis examines certain curves in Riemannian manifolds, which exist in one-one correspondence with other curves. This correspondence is described by means of a rigid link between the frame vectors allied newlineto these quotpairedquot curves. The Combescure transformation is made use of to exhibit that one of the paired curves can be obtained as an infinitesimal deformation of the other. The correspondence between the paired curves is exploited to formulate expressions relating the curvature and torsion functions of one with the other. newlineThe primary setting for this study is the Euclidean space R3, with brief considerations of 3-dimensional Riemannian space forms(i.e. Riemannian manifolds of constant sectional curvature). The exponential map is the desired tool of analysis in the latter case. The major classes of curves treated are the Mannheim class of curves in R3 and their partner curves. Further, with the help of the newlinenotion of the osculating helix, a new class of curves called constantpitch curves are defined, which are seen to naturally arise in motion analysis studies in theoretical kinematics. Constant-pitch curves are newlinealso shown to be inherent counterparts of Mannheim curves by means of a deformation. newlinePivotal properties of Mannheim and constant-pitch curves are established and a few examples are put forth. Integral characterizations of both curves are derived in terms of their spherical indicatrices. A newlineconsequence of this to geometric modeling problems involving energy functionals and also to the study of elastic curves is discussed. newlineCertain ruled surfaces generated by Mannheim and constant-pitch curves which occur as axodes associated to a rigid body motion are newlinedetailed and their applications to kinematics are studied. Further, the nature of paired curves in connection with tubular neighbourhoods/surfaces are investigated. newline -

Relationship Between Industry-Associated Value Premium and Firm Risk Charaterstics on Stock Returns : Evidence From Indian Stock Market
The body of academic literature consistently debates that firms with low PB (price to book) outperform firms with high PB characteristics. This study examines whether the academic literature-promised value premium has any industry association in the Indian equity market and tests the existence of other anomalies: size, investment, profitability, and R&D, in explaining the cross-sectional variability of stock returns. The study considers all BSE-listed firms actively trading between 1999-2021, using time-series, multivariate, and cross-sectional models on each industry-level portfolio. Results indicated that a significant value premium exists in 18 out of 21 industry groups. Both industry and firm-level value premiums are identified; however, the firm-level premium seems more prominent. The value premium is most substantial in small-cap value stocks of value-and-growth-oriented industries, large-cap value stocks of value-oriented industry groups, then small-cap growth stocks of value-and growth-oriented industries and large-cap growth stocks of value- and growth-oriented industries. Interestingly, the sub-period analysis revealed variation in the value premium, indicating that the industry-associated value premium has been relatively low in the current decade. It is due to decreasing tendencies in industry returns and increasing PB in industries. The study explores R&D premium and compares existing factor premiums. Results showed that India's annualized average R&D premium is significantly higher than the current value, profitability, size, and investment premiums, particularly for highly R&D intensive firms. To check the robustness of the findings, the study used the multivariate GRS (Gibbons Ross Shanken) test and the regression models. It confirmed that size and value premiums are the most prominent determinants of industry-level equity returns. The profitability and investment premiums also influence industries' returns. Investors who seek to allocate assets within and across industries are likely to have predictable and stable returns. -
