STUDY OF BOUND AND CONTINUUM STATE BETA DECAY RATES OF A FEW BARE NUCLEI
Beta decay is one of the most widely studied research problems in nuclear physics. There has been a growing interest in understanding the dynamics of beta decay transitions for many decades. Many research groups have invested a lot of time, money and effort in experiments as well as developing the theory for the same. Lot of work was done using Fermis theory and huge amount of data is available in that domain of nuclear physics. But recently, standard model has gained a lot of attention in the eyes of theoretical nuclear physicists and particle physicists to understand nuclear transitions with more importance to gluons mixing and quark mixing by incorporating CKM matrix and PMNS matrix elements. Subsequently, the standard model theory is applied to beta decay to gain a better insight with the application of standard weak interaction Hamiltonian to compute decay rates. The half life and stability of these nuclei depends on decay rates. Also, it gives us an idea about the kind of transitions which happen and which dont. Recent interest in comparison of two modes of beta decay namely, continuum and bound state for same mother and daughter set, paved way for a lot of interesting calculations by various research groups. It is exciting to understand as to how their differences are compared. The aim of this work is to predict continuum and bound state beta decay rates using approach incorporating standard weak theory for some new transitions, which has not been done so far and also compare few decay rates with existing experimental values done by various groups all over the globe. -

Preparation characterization and applications of mixed oxides ceria-samaria supported on rice husk ash as catalysts for organic synthesis
Catalysis is a well-established scientific discipline, dealing with fundamental principles involved in the preparation, properties, applications and mechanisms of catalytic reactions of various catalysts. The preparation of silica from agricultural waste rice husk is an economical and environmentally benign process. Mixed oxides of ceria and samaria are a multifunctional catalytic system that has attracted wide-range of research in different fields. These mixed oxide catalysts are generally used for redox reactions and acid-base reactions in organic synthesis. The catalytic activity of these materials can be enhanced by using silica as a support system. To achieve the best structural and morphological features, different synthetic protocols were tried out while incorporating CeO2 and Sm2O3 on SiO2 to maximize the catalytic efficacy. In the present study, bimetallic oxides of ceria and samaria supported on silica catalysts were prepared by ultra sonicator, rota vapour method, wet impregnation and incipient wet impregnation methods. Further modification of ceria-samaria-silica catalysts using MoO3, La2O3 and mixed forms of MoO3 and La2O3 led to the formation of tri or tetra metallic mixed oxides on silica system. A detailed physico chemical characterization of the prepared catalysts using different spectroscopic and non-spectroscopic methods was carried out to understand the nature, stability and the functional groups present in the system. The heterogeneous catalytic route for organic synthesis is of major interest as it is sustainable and eco-friendlier. Utilizing biowaste like rice husk and its modified forms to synthesize useful and industrially significant organic compounds has been attempted with success in the present work. Thus, the prepared catalysts were subsequently evaluated for their catalytic activity towards oxidation, esterification, transesterification and Friedel Crafts' benzylation reactions. To achieve maximum yield and good selectivity, the different reaction parameters were optimized for all the reactions that were studied. Oxidation of cyclohexanone with benzyl alcohol to caprolactone and benzaldehyde has been studied after optimizing the reaction parameters. Recycle and leaching studies were conducted to understand the stability and reusability of the catalytic system for the above-mentioned reactions. These catalysts were also found effective in the synthesis of caprolactone, which is an intermediate in the synthesis of biodegrading polymers. Selective oxidation of benzyl alcohol to benzaldehyde too has been achieved using these catalysts. Surface area and acidity have played major roles in these reactions. Finally, dibenzyl toluene was synthesized by benzylation of toluene using benzyl chloride. In all the studies, plausible mechanisms involving the catalyst have also been suggested. Thus, a comprehensive study of rice husk silica-supported ceria and samaria systems and the multi metal oxide silica systems has been conducted and it has proved to be an efficient, recoverable, stable and eco-friendly catalyst combined with simple workup for industrially important organic syntheses. -

Children's Well-Being in Traditional Vs. Montessori Schools. A test of Self-Determination Theory
The present study is a test of Self -Determination theory, which is well established in the field of education with a huge body of empirical evidence to support its assumptions that when the three universal psychological needs (Autonomy, Competence & Relatedness) of a child are met they will grow and function optimally leading to enhanced well-being. It is evident that Montessori philosophy is overlapping with the components of SDT. This study was conducted to examine the extent to which the three psychological needs are satisfied in Montessori schools in comparison to the Traditional schools. A purposive sample size of 80 children in elementary grades was selected from both Montessori and Traditional schools. Perceived support experienced by the children and their Well-Being was determined to establish the assumption of the SDT. The results showed that children in Montessori schools experienced greater satisfaction of needs when compared to traditional school children. However, the well-being of children from both school types didn???t vary much and the causes can be attributed to factors outside classroom. These findings have some strong implications for policy makers, educators and parents. -

A study on strategic use of language in newspapers headlines /
The language we use to communicate with one another is like a knife. In the hands of a careful and skilled surgeon, a knife can work to do great good. But in the hands of a careless or ignorant person, a knife can cause great harm. Exactly as it is with our words- Anonymous. For the news media, particularly the newspaper, the greatest weapon is the power of words. The success or failure of a newspaper depends largely on the way its headlines appear to the readers. A well thought out headline does half the job of conveying the message. And consequently, a poorly written one can lead to misinterpretation. This research is an effort to delve into a complete understanding of the structuring of headlines in English newspapers and analyzing it against the use of phrases and words that are misleading and ambiguous. -

Development of personalized diet and exercise recommender system based on clinical data
The present health scenario indicates that thyroid diseases are a common challenge experienced by most individuals. According to the statistics in India, one out of eight women suffer from thyroid-related conditions. Hyperthyroid, hypothyroid, or thyroid cancer are categories of thyroid disorder. It is imperative to maintain optimum levels of secretion of the thyroid hormones as the imbalance could lead to thyroid diseases. Therefore, thyroid patients must be vigilant regarding their iodine intake and follow a customized daily diet and exercise plan. The diet plan, along with balanced iodine levels, must also be able to meet the patient's nutritional needs. A personalized diet plan could help thyroid patients to be more aware and focused on their body metabolism. Existing recommender systems usually provide generic diet recommendations, and unfortunately, it may not be beneficial to patients suffering from a specific disease. Content-based Neighborhood-Conditional RBM (CB-NCRBM) model has posited to recommend Top-3 diet and exercise plans for thyroid patients. The proposed model considers the joint probability distribution of different scores using the user profile. Similarly, preference and health scores are estimated based on content features. The model feeds these scores as visible units to conditional RBM. The proposed model also integrates several content-based features such as users' physiological profiles, thyroid disease information, food, and exercise preferences. The proposed recommender model validates the experimental results using recommendation error and classification accuracy metrics. The proposed hybrid model outperforms several popularly used recommendation models, such as collaborative filtering, content-based, and pure RBM models. The system also provides a feedback loop to enhance the quality of the recommended diet and exercise plans based on user experience. -
