Santiniketan, India

Visva-Bharati University is one of India's major Central Govt. funded autonomous university located in Santiniketan, West Bengal. It was founded by Rabindranath Tagore who called it Visva Bharati, which means the communion of the world with India. In its initial years Tagore expressed his dissatisfaction with the word 'university', since university translates to Vishva-Vidyalaya, which is smaller in scope than Visva Bharati. Until independence it was a college. Soon after independence, in 1951, the institution was given the status of a university and was renamed Visva Bharati University.The English-daily, The Nation notes,"Using the money he received with his Nobel Prize for Literature in 1913, the school was expanded and renamed Visva-Bharati University. It grew to become one of India's most renowned places of higher learning, with a list of alumni that includes Nobel-winning economist Amartya Sen, globally renowned filmmaker Satyajit Ray and the country's leading art historian, R. Siva Kumar, to name just a few" Wikipedia.

The present study was aimed to find out the prevalence of overweight and obesity and its associated factors among Bengalee children and adolescents in the Kolkata, India. A total of 1061 Bengalee school children and adolescents (610 boys and 451 girls) participated and were divided into three age groups: Group I = 8-11 years; Group II = 12-15 years and Group III = 16-18 years. Overweight and obesity were defined as: Overweight (between ≥85 th and <95 th percentile) and obesity (≥95 th percentile). Multivariate regression analyses (adjusted for age and sex) of body mass index (BMI) revealed that about 18% (R2 = 0.185) of total variance of BMI could be explained by monthly family income, participants think obese, consumption of too much junk foodstuffs, breakfast skip, extra consumption of salt, and computer hours. Sedentary lifestyles, including increasing fast food preferences may be responsible for increasing occurrence of pediatric and adolescent obesity in this population.

A simple and energy-efficient green protocol for the synthesis of a series of biologically interesting functionalized bis-lawsone [i.e., 3,3′-(aryl/alkyl-methylene)bis(2-hydroxynaphthalene-1,4-dione)] scaffolds has been developed in the presence of sulfamic acid as an eco-friendly organocatalyst via one-pot pseudomulticomponent reaction at room temperature. The salient features of the present protocol are mild reaction conditions, good to excellent yields, operational simplicity, energy-efficiency, high atom-economy, eco-friendliness, easy isolation of products and no column chromatographic separation. © 2015 American Chemical Society.

Examples of non-Hermitian quantum systems admitting a topological insulator phase are presented in one, two and three space dimensions. All of these non-Hermitian Hamiltonians have entirely real bulk eigenvalues and unitarity is maintained with the introduction of appropriate inner products in the corresponding Hilbert spaces. The topological invariant characterizing a particular phase is shown to be identical for a non-Hermitian Hamiltonian and its Hermitian counterpart, to which it is related through a non-unitary similarity transformation. A classification scheme for topological insulator phases in pseudo-Hermitian quantum systems is suggested. © 2012 IOP Publishing Ltd.

The development in the study of supersymmetric many-particle quantum systems with inverse-square interactions is reviewed. The main emphasis is on quantum systems with dynamical OSp(2|2) supersymmetry. Several results related to the exactly solved supersymmetric rational Calogero model, including shape invariance, equivalence to a system of free superoscillators and non-uniqueness in the construction of the Hamiltonian, are presented in some detail. This review also includes a formulation of pseudo-Hermitian supersymmetric quantum systems with a special emphasis on the rational Calogero model. There are quite a few number of many-particle quantum systems with inverse-square interactions which are not exactly solved for a complete set of states in spite of the construction of infinitely many exact eigenfunctions and eigenvalues. The Calogero-Marchioro model with dynamical SU(1, 1|2) supersymmetry and a quantum system related to the short-range Dyson model belong to this class and certain aspects of these models are reviewed. Several other related and important developments are briefly summarized. © 2012 IOP Publishing Ltd.

Objectives. To study whether the prevalence of overweight and obesity in children and adolescents is restricted by habitat (urban vs rural). Methods. A total of 753 healthy children and adolescents, out of which 293 (159 boys and 134 girls) were collected Santiniketan (rural area) and 460 (241 boys and 219 girls) were from Calcutta and the suburbs (urban area), aged 8 to 18 years took part in the study. Participants were subsequently divided into 3 age groups: group I, 8 to 12 years; group II, 13 to 15 years, and group III, 16 to 18 years. Results. It was observed that the overall prevalence of overweight and obesity in the study was 9.6% and 5.7%, respectively. Urban residence and high level of parental education are associated with overweight and obesity in children and adolescents (R2 = 40.3%). Conclusion. Prevalence of overweight and obesity among children and adolescents is not restricted to any particular habitat and warrants early intervention if this global epidemic is to be checked. © 2011 Asia-Pacific Academic Consortium for Public Health.
