A 4D spacetime embedded in a 5D pseudo-Euclidean space describing interior of compact stars

The present paper provides a new model of compact stars satisfying the Karmarkar condition. The model is obtained by assuming a new type of metric potential for gr r from the condition of embedding class I. The model ...

Abundant traveling wave solutions of the compound KdV-Burgers equation via the improved (G′/G)-expansion method

In this article, we investigate the compound KdV-Burgers equation involving parameters by applying the improved (G′/G)-expansion method for constructing some new exact traveling wave solutions including solitons and periodic ...

Accurate numerical simulation of the far-field tsunami caused by the 2011 Tohoku earthquake, including the effects of Boussinesq dispersion, seawater density stratification, elastic loading, and gravitational potential change

In this study, we considered the accurate calculation of far-field tsunami waveforms by using the shallow water equations and accounting for the effects of Boussinesq dispersion, seawater density stratification, elastic ...

Anisotropic charged stellar models in Generalized Tolman IV spacetime

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 ...

Antimicrobials resistance pattern of escherichia coli collected from various pathological specimens

Irrational use of antibiotics is common in Bangladesh. The purpose of the present study was to know the effectiveness of various commonly used antimicrobials against Escherichia coli. Antimicrobial susceptibility test was ...

Binding of desloratadine and atenolol with bovine serum albumin and their in-vitro interactions

Aims: The binding of atenolol a selective β1 receptor antagonist and desloratadine, an H1 receptor antagonist, to bovine serum albumin. Methods: The analysis of binding was studied by equilibrium dialysis method (ED) using ...

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 ...

Combination of community-based vulnerability and adaptation to storm surges in coastal regions of Bangladesh

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 ...

Comments on information erasure in black hole

We analyze the Kim, Lee and Lee model of information erasure by black holes and find contradictions with standard physical laws. We demonstrate that the erasure model leads to arbitrarily fast information erasure; the ...

Designing novel antibacterials: application of omics science

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 ...

Development of sustain release matrix tablet of ranolazine based on methocel K4M CR: In vitro drug release and kinetic approach

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. ...
