The thesis examines the contemporary Bengali practice of worshipping clay images. By clay is understood 'unbaked' clay. The thesis makes a distinction between 'baked clay' (terracotta) images and 'unbaked' clay (terracruda) images and examines the preference for worshipping terracruda images. The worship of clay images is examined within the context of image worship in general in India, referring to the classical iconographical canons and other texts in which clay is mentioned as a suitable medium for the making of religious icons. The study is restricted to the Hindu religion. The thesis does not restrict itself to a purely iconographical approach. The thesis discusses the artistic tradition that gave rise to the clay images of Bengal,as well as attempting to understand the religious significance of the images. In tracing the tradition, the author has used vernacular sources as well as early records of travellers. In describing the contemporary technique of clay image making, the author has relied on recorded interviews and photo-documentation taken during a three month period of fieldwork in West Bengal. The thesis establishes that there has been a tradition of worshipping clay images in Bengal that is at least two centuries old and suggests that there are earlier precedents for the tradition. It also concludes that it is a strongly regional tradition that developed in Bengal and influenced the neighbouring states of Bihar, Assam and Orissa. The worship of terracruda images in Bengal is a regional practice that is the product of both classical and 'folk' influences.

Luminescence is the emission of light by an object. Living organisms including certain bacteria are capable of luminescence. Bacteria are the most abundant luminescent organisms in nature. Bacterial luminescence has been studied most extensively in several marine bacteria. Bacterial luminescence is due to the action of the enzyme called luciferase. The luminescent bacteria exist in nature either as free living bacteria or in symbiotic association ship with certain marine organisms. Research on luminescent bacteria has always been a fascinating one. In the present study, twenty free living luminescent bacteria were isolated from Bay of Bengal, India using soft agar overlay method in sea water complex agar (SWCA). All the 20 strains were characterized for certain biochemical tests and they were tentatively identified that they are all Photobacterium spp. The effect of salinity, pH glycerol concentration and heavy metals on the growth and luminescence of these 20 strains was also studied. In this part of experiment, visual scoring was done to categorize the luminescence. In case of salinity, it has been found that up to 6% of NaCl the intense of luminescence was good and thereafter it declined. Further, in some strains it was completely ceased beyond 9% of salinity. Luminescence was not greatly affected by pH in liquid medium however; the same was affected in solid medium. The intensity of luminescence has increased with increasing concentrations of glycerol ranging from 0.3 to 1.2%. All the 20 luminescent bacteria were characterized for their tolerance to heavy metals and antibiotics. Copper and zinc at 1 mg/ml concentration have inhibited the growth and luminescence of the all strains. Surprisingly, mercury at the same concentration has inhibited only two strains (AMET1913 and AMET1920). However, at 2 mg/ml concentration mercury has inhibited the growth and luminescence of all the 20 strains. Selected six luminescent bacterial strains were also characterized for their antibiotic susceptibility against six different antibiotics. It has been found that most of the strains were sensitive to all the six antibiotics tested. Since, the bioluminescence is regulated by quorum sensing, the effect of culture filtrate extracted with dichloromethane was also tested for its effect on luminescence. These DCM extracts haven‟t influenced the luminescence much.

Myanmar remained largely closed to the world through political instability for several years, when it continued to suffer terribly at the hands of nature that remained largely unknown. Of note is the period between 2008 and 2013, during which the country suffered at least eight major natural calamities that killed more than 141,000 people and affected 3.2 million. The worst of these was Cyclone Nargis in May 2008 that killed more than 130,000. With an estimated $4 billion in damages, Nargis remains the deadliest and most destructive named cyclone ever to have occurred in the North Indian Ocean. Recent studies have shown that, due to increased greenhouse gases and aerosol loading in the atmosphere, more and stronger tropical cyclones (TCs) in the last three decades are tracking eastwards toward the Indochina peninsula. Unfortunately, the Burmese lack the capacity to deal with the impacts of such storms. Myanmar was left behind as the world made significant technological and industrial advancement; but agriculture, which employs at least 65% of the active labor force, has remained the backbone of the Myanmar economy – an industry that is heavily reliant on monsoon rainfall. The pre-monsoon TC season in the Bay of Bengal (BoB) precedes the onset of the Myanmar monsoon but sometimes the two (i.e.TC formation and the monsoon onset) occur in unison. This work studied the mechanism by which the Madden Julian Oscillation (MJO) modulates the Myanmar monsoon onset and TC activity collectively (i.e. ISO-Onset-TC connection). Avoiding TC destruction at the beginning of the planting season is crucial, so is the monsoon onset date critical for planning. Additional understanding of the aforementioned ISO-Onset-TC connection could provide further insight into predicting the Myanmar monsoon onset and aid in disaster planning for TC impact. This research is part of a two-year NASA funded project to study extreme climate and weather events.

Among the extant examples of carved-stone deity mūrtis from Pāla-period Bengal, few express their subject matter in such dynamic and aesthetically refined visual terms as a sculpture now in the collection of the Metropolitan Museum of Art in New York. Entitled Mañjuvajra Mandala, the stele depicts a three-faced six-armed form of the bodhisattva of wisdom, Mañjuśrī. It dates from the latest phase of Vajrayāna Buddhism in India and likely reflects sādhana practices that entail mandala visualization rituals and union with a female consort. Although a superbly carved piece and an unusual form, it has not yet been fully studied. Surviving relevant texts locate Mañjuvajra primarily within a mandala diagram as the focus of sādhana visualization rituals. The purpose of this thesis is to explore aspects of the sculpture's execution that add to its meaning and, in turn, provide an enriched understanding of Vajrayāna practice. The innovative composition and metonymic forms of this Mañjuvajra sculpture demonstrate the congruency of religious content and artistic depiction in a powerful and multivalent manner. / text

This dissertation is an analysis of discursive productions of Kālīghāṭ, a Hindu temple dedicated to the goddess Kālī in Kolkata (formerly Calcutta), India. It is the most famous temple in what was once the capital of the British Empire in India and what is now India's third largest city. Kālīghāṭ has a reputation for being ancient, powerful, corrupt, and dirty. This dissertation aims to discover how and why these are the adjectives most often used to describe this temple. While there are many stories that can be told about a place, and many words that can be used to characterize it, these four dominate the public discourse on Kālīghāṭ. I demonstrate in these pages that these ideas about Kālīghāṭ are not discoveries made about the site, but are instead creations of it that have been produced at certain times, according to certain discursive practices, toward certain ends.

Natural attenuation of trichloroethene (TCE) and technetium (99Tc) was studied for five consecutive seasons (from January 2002 to January 2003) in Little Bayou Creek. The stream receives ground water discharge from an aquifer contaminated by past waste disposal activities at the Paducah Gaseous Diffusion Plant (PGDP), a uranium enrichment facility near Paducah, Kentucky. Results from stream gaging, contaminant monitoring, tracer tests (with bromide, nitrate, rhodamine WT and propane) and simulation modeling indicate the TCE is naturally attenuated by volatilization and dilution, with volatilization rates related to the ambient temperature and surface discharge rate. The only apparent mechanism of 99Tc attenuation is dilution. Travel times of non-gaseous tracers were found to be similar and have highest values in October and lowest in June. It was also estimated from modeling that the transport of the solutes in the stream was mostly one-dimensional with insignificant secondary storage.
