Diamagnetic susceptibility and binding energy of an exciton in a near triangular quantum well, with potential profile proportional to |z|2/3 composed of GaAs/Ga1−xAlxAs and ZnO/Zn1−xMgxO are calculated as a function of the wellwidth and concentration of Al and Mg respectively varying the magnetic field applied along growth direction (i.e. z-axis). Diamagnetic susceptibility of light hole exciton and heavy hole exciton, shows inverse behaviors in the two materials below 20 nm wellwidth and the binding energy of both excitons increases, as the magnetic field increases. The results obtained, are compared with those of quantum wells with varied potential profiles and the experimental results reported in the literature. © 2016, Indian Association for the Cultivation of Science.

Binding energies of the heavy hole and light hole exciton in a quantum well with Pöschl–Teller (PT) potential composed of GaAs have been studied variationally within effective mass approximation. The effects of pressure and temperature on exciton binding energy are analyzed individually and also simultaneously for symmetric and asymmetric configuration of the well. The results show that exciton binding energy (i) decreases as the well width increases, (ii) increases with pressure and (iii) decreases with temperature. Simultaneous effects of these perturbations lead to more binding of the exciton. The results are compared with the existing literature. © 2017 World Scientific Publishing Company

We have presented a theoretical study on ground state binding energy of the hydrogenic donor in the Surface Quantum Well composed of vacuum/GaAs/Ga1-xAlxAs. The effects of image charges and dielectric screening function on the hydrogenic donor binding energy are analysed. The results indicate that both of them have inverse effects. These results are compared with the results of other potential profiles previously reported. © Penerbit Universiti Sains Malaysia, 2017.

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).

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.

In this paper a new computing model called Hybrid P System is introduced and examined. The aim is to elaborate the power of hybrid P system with prescribed teams and context-free puzzle grammar rules in generating characters. Various non-context free sets of arrays that can be generated in a simple way by hybrid context-free puzzle grammar system with prescribed teams working in different modes are presented in [12]. We show the power of the mechanism of hybridity for picture description on P system. © Springer International Publishing Switzerland 2016.

A new computing model Fuzzy abstract rewriting system on multisets is designed that is closer to reality by introducing fuzziness on computation. The mechanism of Artificial Cell System with hierarchically structurable membrane on chemical reaction is developed with fuzzy multiset evolution rules and fuzzy data. Significance of a parameter on the Fuzzy Artificial Cell System which describes the behaviour of the membrane structure is studied. © Springer International Publishing Switzerland 2016.

Exciton binding energies with temperature in a quantum well with Poschl-Teller Potential formed by ZnSe/Zn1-xMgxSe are calculated theoretically. Using the temperature dependent value of the effective mass and barrier height, the sub-band energies of the electron, heavy hole and light hole are calculated by variational method. Binding Energy of light hole exciton and heavy hole exciton are calculated as a function of the wellwidth for different temperatures. We have obtained the result that the binding energy of exciton decreases with enhancing the temperature and increases with reducing the wellwidth upto 12 nm for heavy hole exciton and 10 nm for light hole exciton, beyond this wellwidth the exciton binding energy decreases. © 2016, Sphinx Knowledge House.

Binding energies of excitons in a Surface Quantum Well (SQW) composed of vacuum/GaAs/AlxGa1-xAs as a function of wellwidth are calculated. The effect of non-parabolicity is considered by using an energy dependent effective mass. The effect of mass anisotropy and the effect of image charges which arise due to the large dielectric discontinuity at the vacuum/GaAs interface are also considered. The average distances of the electron 〈ze〉and the hole 〈zh〉from the vacuum/GaAs interface, with and without image charges and the integrated probability of finding an electron and a hole inside the well are also calculated. The results agree well with the available experimental data. © 2014 Elsevier Ltd. All rights reserved.

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.
