Association of adiponectin gene polymorphism (+T45G) with acute coronary syndrome and circulating adiponectin levels
(
SAGE
, 2012 , Article)
We investigated the association of adiponectin gene polymorphisms (+T45G and +G276T) and adiponectin levels with acute coronary syndrome (ACS) among Arabs in Qatar. A case-control study was performed in 142 Arab patients ...
Unveiling Qatarization: a strategic HRM perspective on the context of implementing successful workforce nationalization
(
Taylor & Francis
, 2023 , Article)
This study is motivated by the infancy of literature on strategic HRM in regard to government policies and the lack of empirical research on the HRM policy of nationalization in the countries of the Gulf Cooperation Council ...
Enhancement of photovoltaic module performance by thermal management using shape-stabilized PCM composites
(
Elsevier
, 2024 , Article)
Thermal management of photovoltaic (PV) panels is crucial due to the deterioration of their electrical efficiency at elevated operating temperatures. Therefore, thermal protection of PV against overheating is highly required. ...
Genetic polymorphisms of ICAM 1 and IL28 as predictors of liver fibrosis severity and viral clearance in hepatitis C genotype 4
(
Elsevier
, 2013 , Article)
Background and objectivesIntercellular adhesion molecule-1 (ICAM-1) is located on chromosome 19p13.2, and this protein plays an important role in the pathogenesis of the hepatitis C virus (HCV). The rs12979860 polymorphism ...
Significant association of close homologue of L1 gene polymorphism rs2272522 with schizophrenia in Qatar
(
Wiley Online Library
, 2012 , Article)
Introduction: Previous reports have found that polymorphisms in the close homologue of L1 (CHL1) gene located on chromosome 3p26 are associated with schizophrenia among different ethnic populations. The aim of this study ...
Harmonic modeling of linear and nonlinear loads based on Kalman filtering algorithm
(
Elsevier
, 2004 , Article)
Most harmonic nonlinear load modeling techniques developed in the last two decades, assume that the load connected to the load bus has a constant admittance, inductive or capacitive, which depends on the mode of operation ...
Fuzzy linear parameter estimation algorithms: A new formulation
(
Elsevier
, 2002 , Article)
In this paper, we present a new formulation of a fuzzy linear estimation problem as one of the linear programming where the objective is to minimize the spread of the data points, subject to constraints on each measurement ...
Sensorless sliding mode observer for a five-phase permanent magnet synchronous motor drive
(
Elsevier
, 2015 , Article)
This paper deals with the sensorless vector controlled five-phase permanent magnet synchronous motor (PMSM) drive based on a sliding mode observer (SMO). The observer is designed considering the back electromotive force ...
Modelling and analysis of a three-phase to five-phase transformer
(
Walter de Gruyter GmbH
, 2014 , Article)
Multi-phase systems are the focus of research in recent times due to their inherent advantages compared to the three-phase counterpart. A lot of research effort has been put to develop commercially feasible multi-phase ...
Frequency and harmonics evaluation in power networks using fuzzy regression technique
(
Elsevier
, 2003 , Article)
A new technique for frequency and harmonic evaluation in power networks is proposed in this paper. This technique is based on fuzzy linear regression and uses the digitized voltage samples, which are fuzzy numbers, to ...
