바라타나티얌(Bharatanatyam) : 한국·일본·인도 삼국의 무속과 의식무용의 세계
Venkataraman, Anuradha 한국예술종합학교 무용원 2001 무용원 이론과 연구자료집 Vol.3 No.-
India has a long and relationship to the esoteric arts of dance, drama and music. It is said that the cultural essence changes every 100 kms in India, so rich and versatile is this ancient country. The folk art forms are many and exotic in nature. The special hallmark of Indian dance forms are the seven classical dance forms namely Kathak from the north, Manipuri and Odissi from the south. All these dance forms have originated from the Natashastra or the science of dance forms have originated from the Natashastra or the science of dance which came into existence before 3000 years. Bharatanatyam is the most ancient among classical dance forms. It mention has been found in the literary works during the period form 500 B.C-500 A.D, proving its antiquity. During 10th century A.D it developed widely in the southern state of India Tamilnadu. This dance from was practised by the "devadasi" community as it was a temple dance and these dancers were servants to god - the "chola" and the "Pallava" dynasties patronized this art form to a great extent. Bharatanatyam at this stage was called Dasiattam. The name Bharatanatyam is more recent. This term Bharatanatyam means - a confluence of expressions, melody and rhythm flowing into stream of dance.
ON IRREDUCIBILITY OF INDUCED MODULES AND AN ADAPTATION OF THE WIGNER-MACKEY METHOD OF LITTLE GROUPS
Venkataraman, Geetha Korean Mathematical Society 2013 대한수학회지 Vol.50 No.6
This paper deals with sufficiency conditions for irreducibility of certain induced modules. We also construct irreducible representations for a group G over a field $\mathbb{K}$ where the group G is a semidirect product of a normal abelian subgroup N and a subgroup H. The main results are proved with the assumption that char $\mathbb{K}$ does not divide |G| but there is no assumption made of $\mathbb{K}$ being algebraically closed.

<P>Although Ocimum sanctum has been used extensively for its medicinal values in India and China, its antitumor activity against human nonsmall cell lung carcinoma (NSCLC) A549 cells has not been investigated until now. Therefore, the antitumor mechanism of ethanol extracts of Ocimum sanctum (EEOS) was elucidated in A549 cells in vitro and the Lewis lung carcinoma (LLC) animal model. EEOS exerted cytotoxicity against A549 cells, increased the sub-G1 population and exhibited apoptotic bodies in A549 cells. Furthermore, EEOS cleaved poly(ADP-ribose)polymerase (PARP), released cytochrome C into cytosol and simultaneously activated caspase-9 and -3 proteins. Also, EEOS increased the ratio of proapoptotic protein Bax/antiapoptotic protein Bcl-2 and inhibited the phosphorylation of Akt and extracellular signal regulated kinase (ERK) in A549 cancer cells. In addition, it was found that EEOS can suppress the growth of LLC inoculated onto C57BL/6 mice in a dose-dependent manner. Overall, these results demonstrate that EEOS induces apoptosis in A549 cells via a mitochondria caspase dependent pathway and inhibits the in vivo growth of LLC, suggesting that EEOS can be applied to lung carcinoma as a chemopreventive candidate.

Microbial biosurfactants surpass synthetic alternatives due to their biodegradability, minimal toxicity, selective properties, and efficacy across a wide range of environmental conditions. Owing to their remarkable advantages, biosurfactants employability as effective emulsifiers and stabilizers, antimicrobial and antioxidant attributes, rendering them for integration into food preservation, processing, formulations, and packaging. The biosurfactants can also be derived from various types of food wastes. Biosurfactants are harnessed across multiple sectors within the food industry, ranging from condiments (mayonnaise) to baked goods (bread, muffins, loaves, cookies, and dough), and extending into the dairy industry (cheese, yogurt, and fermented milk). Additionally, their impact reaches the beverage industry, poultry feed, seafood products like tuna, as well as meat processing and instant foods, collectively redefining each sector’s landscape. This review thoroughly explores the multifaceted utilization of biosurfactants within the food industry as emulsifiers, antimicrobial, antiadhesive, antibiofilm agents, shelf-life enhancers, texture modifiers, and foaming agents.
Characterisation of Tensile Deformation through Infrared Imaging Technique
Baldev Raj, B.Venkataraman,Mukhophadyay, C. K. 한국비파괴검사학회 2002 한국비파괴검사학회지 Vol.22 No.6
It is well known that during tensile testing, a part of the mechanical work done on the specimen is transformed into heat energy. However, the ultimate temperature rise and the rate of temperature rise is related to the nature of the material, conditions of the test and also to the deformation behaviour of the material during loading. The recent advances in infrared sensors and image/data processing techniques enable observation and quantitative analysis of the heat energy dissipated during such tensile tests. In this study, infrared imaging technique has been used to characterise the tensile deformation in AISI type 316 nuclear grade stainless steel. Apart from identifying the different stages during tensile deformation, the technique provided an accurate full-field temperature image by which the point and time of strain localization could be identified. The technique makes it possible to visualise the region of deformation and failure and also predict the exact region of fracture in advance. The effect of thermal gradients on plastic flow in the case of interrupted straining revealed that the interruption of strain and restraining at a lower strain rate not only delays the growth of the temperature gradient, but the temperature rise per unit strain decreases. The technique is a potential NDE tool that can be used for on-line detection of thermal gradients developed during extrusion and metal forming process which can be used for ensuring uniform distribution of plastic strain.

Dehydration of methanol to dimethylether (DME) is an acid catalysed reaction of a commercialimportance. Several solid acid catalysts have been studied (a) to minimize the formation of hydrocarbons during reaction; and (b) to have higher resistance against water when crude methanol containing water (~ 20 mol %) is used as a main feedstock. In our present investigation, a series of TiO2-ZrO2 binary oxides with molar ratios of TiO2 to ZrO2,has been synthesized, characterized and tested for the title reaction in a fixed-bed reactor under normal atmospheric pressure. The objective of the presentation is to bring out the novelty of this new solid acid system with respect to catalytic activity, selectivity for DME and resistance against water during dehydration reaction. Based on our results, a mechanism is proposed as a possible reaction pathway for DME synthesis.
