Fibers on a graph with local load sharing

We study a random fiber bundle model with tips of the fibers placed on a graph having co-ordination number 3. These fibers follow local load sharing with uniformly distributed threshold strengths of the fibers. We have studied the critical behaviour of the model numerically using a finite size scaling method and the mean field critical behaviour is established. The avalanche size distribution is also found to exhibit a mean field nature in the asymptotic limit.Comment: 9 pages, 6 figures, To appear in International Journal of Modern Physics

Most Preferred Business Banking Product of HDFC Bank in Trichy City

Change is the only constant factor in this dynamic world and banking is not an exception. The changes staring in the face of bankers relates to the fundamental way of banking-which is undergoing rapid transformation in the world of today, in response to the forces of completion productivity and efficiency of operations, reduced operating margins better asset/liability management, risk management, any time and any where banking. The major challenge faced by banks today is to protect the falling margins due to the impact of competition. Another significant impact of banks today is the technology issue. In this study the business banking products of HDFC bank, that best suits the needs of the borrower were analysed. The Customer feels that loans to be obtained require a process that is extremely complicating and time consuming. This calls for an ombudsman setup separately for the domain. The observation and findings of the study have helped to give useful recommendation to bank. The implementation of the suggestion can help to improve strategies and build competencies over that of their competitors. This study has there by helped me by giving exposure into new concepts in today’s banking scenario as the interface shifts from service to products. There has also been some insight into competency recognition

Permeability studies and dehiscence of spermatophores

The mechanism of release of sperm from crustacean spermatophores has long been debated. Many factors such as external physical pressure, inbibition of water by substances within and an Qviducal secretion have been suggested to be responsible for the opening up of spermatophores (Mouchet/ 1931 ; Bloch, 1935 ; Subramoniam, 1977)

A morphological investigation on the spermatophores of selected crustaceans

In many decapod crustaceans, the male produces discrete aggregations of spermatozoa embedded in some form of protective covering, termed the spermatophores. They are transferred during mating to the oviduct or merely deposited on the sternum of the females

Biochemical analyses of seminal plasma and spermatophores of Scylla serrata

A volume of information is available on the nature, origin and role of seminal plasma in mammals (Mann, 1964 ; Hafez, 1976). Among invertebrates such information is limited to insects and echinoderms only

The People of Marutham Land: Their Lives and Culture

Social anthropologists have given various interpretations and definitions of culture. Culture is interwoven into the domestic as well as the public life of the people of the Sangam age. The culture of the people of Marutham land depended on agriculture. The people who lived in fertile agricultural lands lived by the disciplines that they could follow. Marriage is considered important and primary in Tamil culture. The Akananooru songs talk about the rituals of marriage. It is understood that "Silambu Kazhi Nonbu" (removal of anklets put on by the parents before the marriage of the girls) was the main ritual in the wedding rituals. The wedding rituals were simple. It is mentioned in the Kalitthokai that wearing new clothes at the time of the wedding, wearing new ornaments, adorning with garlands of flowers, and circumambulating the fire as guided by the Brahmin during the time of the wedding

Radial flow of kaon mesons in heavy ion reactions

This work investigates the collective motion of kaons in heavy ion reactions at SIS energies (about 1-2 GeV/nucleon). A radial collective flow of $K^+$ mesons is predicted to exist in central Au + Au collisions, which manifests in a characteristic "shoulder-arm" shape of the transverse mass spectrum of the midrapidity $K^+$ mesons. The $K^+$ radial flow arises from the repulsive $K^+$ mean field in nuclear matter. In spite of a strong reabsorption and rescattering the attractive $K^-$ mean field leads as well to a collective radial flow of $K^-$ mesons. The $K^-$ radial flow, however, is different from that of $K^+$ mesons and can be observed by a characteristic "concave" structure of the transverse mass spectrum of the $K^-$ mesons emitted at midrapidity. The kaon radial flows can therefore serve as a novel tool for the investigation of kaon properties in dense nuclear matter.Comment: 30 pages RevTex, 5 PS figures, accepted for publication in Phys.

Measuring visual cortical oxygenation in diabetes using functional near-infrared spectroscopy

Aims: Diabetes mellitus affects about 6% of the world’s population, and the chronic complications of the disease may result in macro- and micro-vascular changes. The purpose of the current study was to shed light on visual cortical oxygenation in diabetic individuals. We then aimed to compare the haemodynamic response (HDR) to visual stimulation with glycaemic control, given the likelihood of diabetic individuals suffering from such macro- and micro-vascular insult. Methodology: Thirty participants took part in this explorative study, fifteen of whom had diabetes and fifteen of whom were non-diabetic controls. The HDR, measured as concentrations of oxyhaemoglobin [HbO] and deoxyhaemoglobin [HbR], to visual stimulation was recorded over the primary visual cortex (V1) using a dual-channel oximeter. The stimulus comprised a pattern-reversal checkerboard presented in a block design. Participants’ mean glycated haemoglobin (HbA1c) level (±SD) was 7.2±0.6% in the diabetic group and 5.5±0.4% in the non-diabetic group. Raw haemodynamic data were normalised to baseline, and the last 15 s of data from each ‘stimulus on’ and ‘stimulus off’ condition were averaged over seven duty cycles for each participant. Results: There were statistically significant differences in ∆[HbO] and ∆[HbR] to visual stimulation between diabetic and non-diabetic groups (p<0.05). In the diabetic group, individuals with type 1 diabetes displayed an increased [HbO] (p<0.01) and decreased [HbR] (p<0.05) compared to their type 2 counterparts. There was also a linear relationship between both ∆[HbO] and ∆[HbR] as a function of HbA1c level (p<0.0005). Conclusions: Our findings suggest that fNIRS can be used as a quantitative measure of cortical oxygenation in diabetes. Diabetic individuals have a larger HDR to visual stimulation compared to non-diabetic individuals. This increase in ∆[HbO] and decrease in ∆[HbR] appears to be correlated with HbA1c level
