In this paper an inventory model for deteriorating items with time dependent quadratic demand and permissible delay in payments is developed. Shortages are allowed and are partially backlogged. An optimal policy that minimizes the total cost is developed. The objective of this study is to consider three different types of continuous probabilistic deterioration functions and to find the associated total cost. To illustrate the proposed model some numerical examples are given. Sensitivity analysis of the optimal solutions with respect to major parameters are carried out and comparison is made between the three models. Source

The Binding Energy of an exciton in a Near Triangular Quantum Well (NTQW) composed of Ga1-xAlxAs/GaAs/Ga1-xAlxAs with potential profile proportional to |z|2/3 is calculated as a function of the quantum wellwidth (L) and barrier height(V0) with uniform magnetic field applied along growth direction (i.e z-axis). In-plane electron-hole distance <ρ2>1/2, distance of the electron and hole respectively from the well center 1/2 and 1/2 are also calculated. The results are compared with those of quantum wells with other potential profiles and available experimental data. © 2015, Sphinx Knowledge House. All rights reserved. Source

Vermitechnology provides scope and opportunities in the field of Biotechnology. The sudden decline in earthworm biomass may mainly be due to the over use of chemicals. Steps had been taken to enhance the production of biomass of earthworms by providing organic wastes rich in major organic constituents such as cereals, pulses and skin of chick. Earthworms (Eudrilus eugienea) were fed with organic constituents individually, and in combination of organic rich diet. The biomass of the earthworm was steadily increasing in the individual treatment was found when fed with organic rich diet at 10, 20 and 30 days respectively 09.987, 13.569 and 18.212. The bacterial counts in the gut of earthworms were 543 x 105 CFU ml-1. The bacteria identified were Bacillus spp., Lactobacillus spp and Flavobacterium spp. Enzymes screened in the gut were amylase, endoglucanase, cellulase, sucrase and protease. From the present investigation, it was found that the organic rich diet is the ideal medium in which the biomass of earthworms are high, their enzymatic activity was also high with variety of microbes which will enhance the efficiency of the soil. © Triveni Enterprises, Lucknow (India).
