Immunomodulation Induced by Host Pathogen Interaction
(
Hindawi
, 2019 , Article)
Controlling and preventing infections require deep understanding of the complex interplay that occurs between the host and pathogen following infection. In essence, immunomodulation is any process leading to an immune ...
A Model-driven Approach to the development of a PBL Script Editor
(
Global Chinese Conference on Computers in Education (GCCCE)
, 2013 , Article)
Designing a pedagogically sound and technically executable collaboration script is a highly complex,
time-consuming and error-prone task. This paper presents a model-driven approach to enable practitioners to design
online ...
Fixing the Kingdom: Political Evolution and Socio-Economic Challenges in Bahrain
(
Georgetown University School of Foreign Service in Qatar
, 2008 , Article)
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 ...
Systematic Review of the Respiratory Syncytial Virus (RSV) Prevalence, Genotype Distribution, and Seasonality in Children from the Middle East and North Africa (MENA) Region
(
MDPI
, 2020 , Article)
Respiratory syncytial virus (RSV) is one of the most common viruses to infect children worldwide and is the leading cause of lower respiratory tract illness (LRI) in infants. This study aimed to conduct a systematic review ...
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 ...
Conditions for student-centered teaching and learning in Qatari elementary math and science classrooms: Relationship between classroom processes and achievement of curriculum standards
(
Bloomsbury Qatar Foundation Journals
, 2013 , Article)
Qatar K-12 school reform emphasizes student-centered classrooms where students actively engage in
enquiry and use their critical thinking and problem solving skills. Classrooms characterized by these
elements should ...
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 ...
