Revealing the effects of ill global eco-financial systems and their capsules

This paper examines the origins of the global crisis, the impact of the crisis and the different capsules taken to address the crisis. Using daily data from mid-July 2002 to mid-July 2012 for five groups of economies, our estimation is based on BEKK diagonal GARCH. We augmented two dummy variables to represent the U.S. financial crisis and the debt crisis of Greece. We find that the U.S crisis has insignificant impact on the mean returns of all the economies except the African economies. The U.S. financial crisis, however, has positive and significant impact on the stock volatilities of all the groups except the African economies. The debt crisis of Greece, on the other hand, has negative and significant impact on the mean returns of the European and Latin American economies. Its impact on the stock volatilities, however, is positive and significant in all the economies except the African economies. In examining the origins of the crisis, we identify that excessive reliance of the U.S. economy on the credit system and on the stock market together with historic negligence of the production sector and inadequate regulation are some causative factors

Influence of the Intensity of Irradiation on the New Light-Effect in Chlorine Under Electrical Discharge

General conditions for the production of a new light-effect, viz., a photo-diminution of the conductivity in chlorine subjected to electrical discharge, arc indicated. The effect increases by Increasing the frequency of irradiation, the violet being most active, which happens to be the region of absorption by chlorine. In agreement with Joshi's views, who regards this phenomenon as distinct from a negative photo-electric effect, the influence of the light-intensity on the effect is not linear

A Single-step Process to Convert Karanja Oil to Fatty Acid Methyl Esters Using Amberlyst15 as a Catalys

Karanja oil was successfully converted to fatty acid methyl esters (FAME) in a single-step process using Amberlyst15 as a catalyst. A methanol to oil ratio of 6 was required to retain the physical structure of the Amberlyst15 catalyst. At higher methanol to oil ratios, the Amberlyst15 catalyst disintegrated. Disintegration of Amberlyst15 caused an irreversible loss in catalytic activity. This loss in activity was due to a decrease in surface area of Amberlyst15, which was caused by a decrease in its mesoporous volume. It appeared that the chemical nature of Amberlyst15 was unaffected. Reuse of Amberlyst15 with a methanol to oil ratio of 6:1 also revealed a loss in FAME yield. However, this loss in activity was recovered by heating the used Amberlyst15 catalyst to 393 K. The kinetic parameters of a power law model were successfully determined for a methanol to oil ratio of 6:1. An activation energy of 54.9 kJ mol–1 was obtained.

Persistent currents in coupled mesoscopic rings

We have analysed the nature of persistent currents in open coupled mesoscopic rings. Our system is comprised of two ideal loops connected to an electron reservoir. We have obtained analytical expressions for the persistent current densities in two rings in the presence of a magnetic field. We show that the known even-odd parity effects in isolated single loops have to be generalised for the case of coupled rings. We also show that when the two rings have unequal circumferences, it is possible to observe opposite currents (diamagnetic or paramagnetic) in the two rings for a given Fermi level.Comment: Submitted to PRB. 9 figures availabel on reques

Influence of protein deficiency on 19S antibody-forming cells in rats and mice

Influence of protein deficiency on immune response to sheep red blood cells was investigated in rats and mice with Jerne's plaque-forming cell technique. Protein deficiency resulted in a reduction in the number of antibody-producing cells consequent upon a prolongation of cell generation time in rats. Injection of syngeneic thymocytes brings about better improvement in the immune response of the X-radiated protein-deficient mice as compared to the controls. It is suggested that depressed immunity in malnutrition may be partly due to a disturbance in thymic function
