Designing novel antibacterials: application of omics science
(© 2013 AVES Ibrahim Kara, 2013)Antibacterials are agents that act against pernicious bacterial pathogens by killing or inactivating them. At present, designing antibacterials have been assisted greatly by omics sciences-genomics, proteomics, metabolomics ... -
Kaposi's sarcoma: a computational approach through protein-protein interaction and gene regulatory networks analysis
(© 2012 Springer Science+Business Media New York, 2013)Interactomic data for Kaposi's Sarcoma Associated Herpes virus (KSHV) - the causative agent of vascular origin tumor called Kaposi's sarcoma - is relatively modest to date. The objective of this study was to assign functions ... -
Combination of community-based vulnerability and adaptation to storm surges in coastal regions of Bangladesh
(© 2014 World Scientific Publishing Co. Pte Ltd, 2014)Bangladesh has been identified as one of the countries most vulnerable to climate change and rising sea-level. This is because it is located at the northern end of the funnel-shaped Bay of Bengal, and as a consequence it ... -
Power allocation for the network coded cognitive cooperative network
(© 2011 IEEE, 2011)Demand for higher data rate wireless applications has led to scarcity in radio frequency spectrum. This article focuses the power allocation for the network coded cognitive cooperative network (NCCCN). Analog network coded ... -
Neuro-fuzzy-based hand-off and opportunistic spectrum access for cognitive cooperative network
(© 2012 Inderscience Enterprises, 2012-04)This paper investigates neuro-fuzzy (NF)-based opportunistic spectrum access and spectrum hand-off (HO) for a cognitive cooperative network (CCN). The main aim is to increase the average throughput of the CCN. Secondary ... -
Evaluation of three immunological tests for the diagnosis of pulmonary tuberculosis in a rural endemic area of Bangladesh
(© 2014 Elsevier Ltd, 2014-06)Objective: Bangladesh is a high tuberculosis burden country. It is always challenging to diagnose active pulmonary tuberculosis (PTB) cases in rural areas where the setting up of conventional microscopic and cultural ... -
Isolation of yeasts from raisins and Palm-juice and ethanol production in molasses medium
(© 2016 Indian Society for Education and Environment, 2016)The alternative fuels are expected to satisfy the progressive demand for energy on the wake of the negative effects of fossil fuel on the atmosphere and resultant universal warming. In this study two ethanol fermenting ... -
A class of relativistic anisotropic charged stellar models in isotropic coordinates
(© 2014, Springer Science+Business Media Dordrecht., 2014)In this present paper, we present a class of static, spherically symmetric charged anisotropic fluid models of super dense stars in isotropic coordinates by considering a particular type of metric potential, a specific ... -
A class of super dense stars models using charged analogues of Hajj-Boutros type relativistic fluid solutions
(© 2014, Springer Science+Business Media New York, 2014-10)We present a spherically symmetric solution of the general relativistic field equations in isotropic coordinates for perfect charged fluid, compatible with a super dense star modeling. The solution is well behaved for all ... -
Anisotropic charged stellar models in Generalized Tolman IV spacetime
(© 2015, Società Italiana di Fisica and Springer-Verlag Berlin Heidelberg, 2015)With the presence of electric charge and pressure anisotropy some anisotropic stellar models have been developed. An algorithm recently presented by Herrera et al. (Phys. Rev. D 77, 027502 (2008)) to generate static ... -
Growing electrostatic modes in the isothermal pair plasma of the pulsar magnetosphere
(© 2011 Springer Science+Business Media B.V., 2012)It is shown that a strongly magnetized isothermal pair plasma near the surface of a pulsar supports low-frequency (in comparison to electron cyclotron frequency) toroidal electrostatic plasma modes in the equatorial region. ... -
Optical solitons in negative-index meta-materials
(© 2013 IEEE, 2013)The nonlinear propagation of gigahertz electromagnetic wave propagation in the resonant region of a negative index meta-material is investigated. It is found that the negative refractive index is maintained within a narrow ... -
Langmuir dark solitons in dense ultrarelativistic electron-positron gravito-plasma in pulsar magnetosphere
(© 2013 Springer, 2013)Nonlinear propagation of electrostatic modes in ultrarelativistic dense elelectron-positron gravito-plasma at the polar cap region of pulsar magnetosphere is considered. A nonlinear Schrödinger equation is obtained from ... -
Development of sustain release matrix tablet of ranolazine based on methocel K4M CR: In vitro drug release and kinetic approach
(© 2011 Journal of Applied Pharmaceutical Science, 2011-10)In this study an attempt was made to design and evaluate oral sustained release matrix tablets of ranolazine using Methocel K4M CR as the retardant polymer. Tablets were prepared by conventional wet granulation technique. ... -
