Significance of radiation models in investigating the flow phenomena around a Jovian entry body

Formulation is presented to demonstrate the significance of a simplified radiation model in investigating the flow phenomena in the viscous radiating shock layer of a Jovian entry body. The body configurations used are a 55 degree sphere cone and 50 degree hyperboloid. A nongray absorption model for hydrogen-helium gas is developed which consists of 30 steps over the spectral range of 0 to 20 eV. By employing this model, results were obtained for temperature, pressure, density, the shock layer and along the body surface. These are compared with results of two sophisticated radiative transport models available in the literature

Nucleophilicity/Electrophilicity Excess in Analyzing Molecular Electronics

Intramolecular electron transfer capability of all metal aromatic and anti-aromatic aluminum cluster compounds is studied in terms of density functional theory based global and local reactivity descriptors. This study will provide important inputs towards the fabrication of the material required for molecular electronics.Comment: 21 pages, 6 figures, 13 table

Short and long-term relationship between physician density on infant mortality: a longitudinal econometric analysis

While countries with higher levels of human resources for health typically have better population health, the evidence that increases in the level of human resources for health leads to improvements in population health is limited. We provide estimates of short-run and long-term effects of physician density on infant mortality. We use a dynamic regression model that allows an estimation of both short- and long-run effects of physician density on infant mortality. We also used instrumental variables analysis to identify the causal effect of physician density on health. We estimate that increasing the number of physicians by one per 1,000 population decreases the infant mortality rate by 15% within five years and by 45% in the long-run. We find all countries are moving towards their own steady state at around 3% a year and are only half way there after 15 years. We conclude that the long-run effects of human resources for health are substantially larger than previously estimated. Our results suggest that health sector inputs can play a role in reducing infant mortality. However, meeting the Millennium Development Goal of reducing child mortality rate by two thirds from 1990 to 2015 would have required much earlier action.Physician density, infant mortality, longitudinal, eocnometric

Sugars of pearl millet [Pennisetum americanum (L.) Leeke] grains

The sugars in the grains of nine pearl millet cultivars were fractionated through a Biogel column. Five different sugars‘(stachyose, raffinose, sucrose, glucose, and fructose) were identified. Sucrose was predominant in all the cultivars. Raffinose content was high as compared to other cereals, and maltose was absen

A small concentration of Penaeus japonicus off the north Tamil nadu coast

The Kuruma prawn, Penaeus Japonicus, which is endemic to northwest and western central Pacific regions around Japan, Korea and Papua-Guinea has been reported to occur in small concentrations off the Indian coasts in isolated areas. It forms a small fishery off Mumbal. Its Juvenile abundance has been reported from the backwaters adjoining Chennai. Being a larger species fetching better price, its availability in the Cuddalore region arouses considerable commercial interes
