Bahrain has entered into a more ‘progressive’ phase of its history under King Hamad bin Isa Al Khalifa. Various parliamentary and legislative restructuring, in addition to discernable changes within civil society, have ...
On the numerical simulation of population dynamics with density-dependent migrations and the Allee effects
(
IOP Publishing
, 2008 , Article)
In this paper, the variational iteration method (VIM) and the Adomian decomposition method (ADM) are presented for the numerical simulation of the population dynamics model with density-dependent migrations and the Allee ...
The modified homotopy perturbation method for solving strongly nonlinear oscillators
(
Elsevier
, 2009 , Article)
In this paper we propose a reliable algorithm for the solution of nonlinear oscillators. Our algorithm is based upon the homotopy perturbation method (HPM), Laplace transforms, and Padé approximants. This modified homotopy ...
K-shell photoionization of O+ and O2+ ions: Experiment and theory
(
American Physical Society
, 2015 , Article)
Absolute cross sections for the single and double K-shell photoionization of carbon like O2+ and nitrogen like O+ ions were measured in the 526–620-eV photon energy range by employing the ion-photon merged-beam technique ...
Application of statistical experimental design for optimisation of bioinsecticides production by sporeless Bacillus thuringiensis strain on cheap medium
(
Sociedade Brasileira de Microbiologia - SBM
, 2014 , Article)
In order to overproduce bioinsecticides production by a sporeless Bacillus thuringiensis strain, an optimal composition of a cheap medium was defined using a response surface methodology. In a first step, a Plackett-Burman ...
TiO2 nanotubes with ultrathin walls for enhanced water splitting
(
Royal Society of Chemistry
, 2015 , Article)
We demonstrate, for the first time, the synthesis of titania nanotubes
with ultrathin (3–5 nm) wall thickness. As revealed by the incident
photon-to-current collection efficiency (IPCE) and electrochemical
impedance ...
Isolation of the Bacillus thuringiensis plasmid carrying Bacthuricin F4 coding genes and evidence of its conjugative transfer
(
The Journal of Infection in Developing Countries
, 2014 , Article)
INTRODUCTION:
Conjugation is an excellent natural mode of DNA transfer in vivo between bacteria, particularly when these conjugative elements carry technological traits such as bacteriocin encoding genes. In the present ...
