A Path Analysis of Student Interest in STEM, with Specific Reference to Qatari Students
(
Modestum
, 2017 , Article)
ABSTRACT
This study sought to explore the factors that help predict students’ interest in Science, Technology, Engineering and Mathematics (STEM) in Qatar. Drawing on recent work in the field, the present paper examines ...
Potential psychosocial influences on gender differences in physical activity among Qatari adolescents: a first insight through descriptive observation
(
Taylor & Francis Open
, 2018 , Article)
Adolescents in Qatar have some of the highest levels of inactivity and gender inequality in physical activity (PA) among all adolescents in the world. Contextual psychosocial influences remain unknown to date. The current ...
Association between Genetic Variants of GC Gene at 4q13.3 and Vitamin D Concentrations in Adult Females
(
Longdom
, 2019 , Article)
Background: Vitamin D binding protein, encoded by the GC gene (on 4q13.3), plays an important role in
transporting vitamin D. Several Genome-Wide Association Studies (GWASs) have established a significant
association ...
K-shell photoionization of O4 + and O5 + ions: Experiment and theory
(
Oxford University Press
, 2017 , Article)
Absolute cross-sections for the K-shell photoionization of Be-like (O4 +) and Li-like (O5 +) atomic oxygen ions were measured for the first time (in their respective K-shell regions) by employing the ion-photon merged-beam ...
K-Shell Photoionization of the Oxygen Isonuclear Sequence
(
Institute of Physics Publishing
, 2015 , Conference Paper)
K-shell photoionization cross-section measurements for the oxygen isonuclear sequence from N-like to Li-like made at the SOLEIL Light Source are compared with SUNC, MCDF and R-matrix calculations.
Impacts of urbanization on the distribution of heavy metals in soils along the Huangpu River, the drinking water source for Shanghai
(
Springer Berlin Heidelberg
, 2015 , Article)
We investigated the horizontal and vertical distribution of heavy metals (Hg, Pb, Zn, Cu, Cd, As, Ni, and Cr) in soils in the water source protection zone for Shanghai to study the origins of these metals, their connections ...
Overcome of carbon catabolite repression of bioinsecticides production by sporeless Bacillus thuringiensis through adequate fermentation technology
(
Hindawi Publishing Corporation
, 2014 , Article)
The overcoming of catabolite repression, in bioinsecticides production by sporeless Bacillus thuringiensisstrain S22 was investigated
into fully controlled 3 L fermenter, using glucose based medium. When applying adequate ...
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 ...
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 ...
Experimental Diabetes Mellitus in Different Animal Models
(
Hindawi
, 2016 , Article)
Animal models have historically played a critical role in the exploration and characterization of disease pathophysiology and target identification and in the evaluation of novel therapeutic agents and treatments in vivo. ...
