This species is named in honour of Dr D. C. F. Rentz, Australia. Discussion. The new species is completely differs from P. spinosa, P. myllocerca, P. falcata and P. gracilis on the structure of subgenital plate, supra anal plate, pronotum and fastigium vertices. P. rentzi, sp. nov. is entirely differ from the P. spinosa, P. myllocerca and P. falcata by the shape of cerci and subgenital plate. P. gracilis and P. rentzi, sp. nov. are look-alike however, the subgenital plate is entirely different (Fig. 1j, m).

Folk Literature in Nalayira Divya Prabandham
No full textFolk literature is the mirror of society. Folk literature reflects the experiences and feelings of the rural people. The customs, rituals, ceremonies and traditions of the country people are expressed in folk literature. The nature of folk literature is seen in many ways. One of them is Nalayira Divya Prabandham, the Vaishnava literatry work. The Alwars composed hymns describing the virtues of Tirumal's marriage and incarnations and showed it up in folk literature. Alwars also sung many lullabies. They have sung a folk song called "Pallandu Vaalththu”. The nature of a woman who is in love with God can be known through the proverbs. Alwars have shown that they celebrated festivals two thousand years ago itself. The repetition of a word in folk literature is one of its characteristics. The opinions of scholars related to folklore are explained in this article. This article reflects the nature of folk literature in Nalayira Divya Prabandham

Merchants of Virtue
No full textMerchants of Virtue explores the question of what it meant to be Hindu in precolonial South Asia. Divya Cherian presents a fine-grained study of everyday life and local politics in the kingdom of Marwar in eighteenth-century western India to uncover how merchants enforced their caste ideals of vegetarianism and bodily austerity as universal markers of Hindu identity. Using legal strategies and alliances with elites, these merchants successfully remade the category of “Hindu,” setting it in contrast to “Untouchable” in a process that reconfigured Hinduism in caste terms. In a history pertinent to understanding India today, Cherian establishes the centrality of caste to the early-modern Hindu self and to its imagination of inadmissible others.
“A refreshingly different perspective on the history of caste and untouchability in India, enlarging the field of scholarship from its focus on the colonial era by telling us how precolonial configurations of power in the locality shaped the everyday experience of caste.” — GOPAL GURU, coauthor of The Cracked Mirror and Experience, Caste, and the Everyday Social
“This provocative and empirically rich study offers a plenitude of fascinating insights into aspects of western Indian history ca. 1800, from kingship and caste hierarchy to abortion and alcohol consumption. Particularly innovative is its focus on the critical role played by merchants in articulating social identities that became widespread in modern times.” — CYNTHIA TALBOT, author of The Last Hindu Emperor
“A pathbreaking book that explodes essentialist views of the construction of Hindu and Muslim identities in precolonial India. Divya Cherian provocatively argues that the category of ‘Hindu’ was the primary locus for a system of radical othering that excluded Untouchables (and Muslims as Untouchables) through mechanisms of state, law, and everyday life.” — CHRISTIAN LEE NOVETZKE, Professor of South Asian and Religious Studies, University of Washingto

Improved collision detection in StarLogo Nova
No full textThesis: M. Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2015.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (page 65).StarLogo Nova is blocks-based educational software that allows students to write and play their own 3D games online. It is the online version of StarLogo TNG. This thesis explores the problem of needing more accurate collision detection in StarLogo Nova while maintaining reasonable performance. Three new collision detection systems for StarLogo Nova are developed and evaluated. Compared to the spheres used to perform collision checks in the current system, the first new system, called the TightestFitCollider, introduces a variety of bounding spheres, bounding boxes, and bounding capsules as bounding structures that may fit the models in StarLogo Nova more closely. The second system, called the HierarchicalCollider, uses hierarchies of bounding boxes to perform even more precise collision detection than the TightestFitCollider. Finally, the third system combines the first two systems, so that the advantages of each can be used as appropriate. The three systems are evaluated for their accuracy and performance within the StarLogo Nova framework.by Divya Bajekal.M. Eng

Antiepileptic drugs for the primary and secondary prevention of seizures after subarachnoid haemorrhage
No full textBackground: subarachnoid haemorrhage may result in seizures both acutely and in the longer term. The use of antiepileptic drugs (AEDs) in the primary and secondary prevention of seizures after subarachnoid haemorrhage is uncertain, and there is currently no consensus on treatment.Objectives: to assess the effects of AEDs for the primary and secondary prevention of seizures after subarachnoid haemorrhage.Search methods: we searched the Cochrane Epilepsy Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (2013, Issue 1) in The Cochrane Library, and MEDLINE (1946 to 12th March 2013). We checked the reference lists of articles retrieved from these searches.Selection criteria: we considered all randomised and quasi-randomised controlled trials in which patients were assigned to a treatment (one or more AEDs) or placebo.Data collection and analysis: two review authors (RM and JK) independently screened and assessed the methodological quality of the studies. If studies were included, one author extracted the data and the other checked it.Main results: no relevant studies were found.Authors' conclusions: there was no evidence to support or refute the use of antiepileptic drugs for the primary or secondary prevention of seizures related to subarachnoid haemorrhage. Well-designed randomised controlled trials are urgently needed to guide clinical practice
Enhanced Photocatalytic Degradation of Industrial Dye by g-C3N4/TiO2 Nanocomposite: Role of Shape of TiO2
No full textEnhanced photodegradation of RhB dye by using synthesized g-C3N4/TiO2 nanocomposite having different shapes of TiO2, showing role of shape of TiO2 in photodegradation has been demonstrated in this present work. As TiO2 has a wide band gap of 3.2 eV and utilize energy of radiations of only UV region of light, so has some limitations as a photocatalyst. To improve the photocatalytic efficiency of TiO2 we have incorporated g-C3N4, a visible light active photocatalyst. The TiO2 nanoparticles with different shapes (Nanorods, Nanospheres, and Nanotubes) were prepared by different methods. The g-C3N4 was prepared by pyrolysis of Urea. The g-C3N4/TiO2 composites were prepared by stirring g-C3N4and pre-synthesized TiO2 nanoparticles. The ratio of g-C3N4 and TiO2 nanoparticles is 1:1. On performing photocatalytic experiment we have found that the degradation of RhB dye under visible light irradiation has been increased remarkably upon incorporation of g-C3N4 with different shapes of TiO2. Also, shape of TiO2 has a remarkable effect in photodegradation. The best degradation performance of ∼97% was obtained from g-C3N4/TiO2 (Nanorods) composite. Although, degradation efficiency of composite of other shapes of TiO2 (Nanospheres and Nanotubes) with g-C3N4 were also found to be greater than that of g-C3N4/TiO2 (P25) composite. Results from UV–Vis absorption study, X-ray Diffraction studies, and X-ray photoelectron spectroscopy suggest that the improvement in photocatalytic activity of composite is due to decrease in band gap energy and increased light absorption in visible region. Also there is an increase in electron hole separation efficiency due to effectual interfacial transfer of electron between g-C3N4 and TiO2 (NR, NS, NT) of g-C3N4/TiO2 composites. The BET surface area analyzer, HRTEM, FESEM and Electron Diffraction studies with Color mapping indicate successful incorporation of g-C3N4 with TiO2 in the composites. Results from scavenger study indicate that electron and superoxide ions act as main reactive species in photodegradation of RhB dye by the composite
