Oxidative Stress Markers In Gestational Diabetes Mellitus
(
De Gruyter
, 2015 , Conference Paper)
Oxidative stress is typically the result of an imbalance between the reactive oxygen species (ROS) and the antioxidant. The increased production of ROS could lead into some serious physiological problems on the cell, such ...
A promising drug lead that inhibits HCV infectivity in a genotype-independent manner
(
OMICS
, 2015 , Conference Paper)
E2 glycoprotein plays a significant role in the HCV life cycle, but only crystal structures of short peptides, or epitopes were present until Kong et al. resolved the new HCV E2 core (E2c) crystal structure. We have created ...
Teaching writing in Qatari early years education: the perceptions of early childhood teachers
(
Hamad bin Khalifa University Press (HBKU Press)
, 2015 , Conference Paper)
The present study aimed at 1) exploring early childhood teachers' perceptions about teaching writing in Qatari early years settings, and 2) identifying the impact of several social-demographics variables on these views. ...
How to improve sustainability inside higher educational institutions: A strategic plan for Qatar University
(
Hamad bin Khalifa University Press (HBKU Press)
, 2015 , Conference Paper)
Designing and implementing sustainable solutions means to take responsibility for the welfare of future generations as well as for our environment and planet. Positive approach towards sustainability should be an essential ...
An asymmetrical six-phase induction motor drive based on nine-arm Modular Multilevel Converter (9AMMC) with circulating current suppression
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Asymmetrical six-phase (dual three-phase) induction motors have received significant attention in high power medium voltage drive applications. Normally, two three-phase voltage source converters are used to supply the ...
A cascaded boost inverter-based open-end winding three-phase induction motor drive for photovoltaic-powered pumping applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Although PWM inverter-fed drives are now a well-established technology in industrial applications, the generation of common mode voltage associated with these modulation techniques results in undesired bearing current and ...
High voltage pulse generator based on DC-to-DC boost converter with capacitor-diode voltage multipliers for bacterial decontamination
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
High voltage pulse generators can be used effectively in water treatment applications, as applying a pulsed electric field on the infected sample guarantees killing of harmful germs and bacteria. In this paper, a new high ...
A grid-connected cascaded H-bridge multilevel converter with quasi seven-level Selective Harmonic Elimination
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, a high power grid-connected cascaded H-bridge multilevel inverter (CHB-MLI) operating with Selective Harmonic Elimination (SHE) is presented complying with the low switching frequency operation limitation. ...
A directional protection technique for MTDC networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper suggests a new protection algorithm for a multi-terminal direct current (MTDC) networks. The current values and directions at each bus connecting more than one line are determined. The measured values of line ...
Performance assessment of inductive power transfer for railway applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Inductive power transfer (IPT) is used to transfer the power over relatively large air gap using the resonant phenomena. The use of IPT in the railway transportations enhances the system performance in terms of reducing ...
