EFFECT MODIFICATION OF THE ASSOCIATION BETWEEN DIETARY PATTERNS AND DEPRESSION BY DIABETES AMONG ADULTS IN QATAR: A POPULATIONBASED STUDY
(Health Sciences, 2022 , Master Thesis)
Background: Diabetes is a major public health problem in Qatar and significantly
increases the risk of depression. Dietary patterns are related to the incidence of
depression among patients with diabetes. However, no ...
Biodiversity of Ant Fauna (Hymenoptera: Formicidae) in Qatar
(Biological and Environmental Science, 2021 , Dissertation)
Information on Formicidae of Qatar as well as insect fauna is poorly documented. So
far only six species of Formicidae (ants) belonging to five genera have been recorded
from Qatar; Brachyponera sennaarensis, Cataglyphis ...
Goodness of Fit Testing for the Log-Logistic distribution Based on Type I Censored Data
(Applied Statistics, 2021 , Master Thesis)
The main aim of this thesis is to investigate the problem of the goodness of fit
test for Log-Logistic distribution based on empirical distribution function under Type
I censored data. The maximum likelihood estimation ...
Factors of the Asymmetric Non-Uniform DIF Detection Rate When Using the Alternative Mantel-Haenszel Procedure
(Applied Statistics, 2020 , Master Thesis)
Test-item bias has become an increasingly challenging investigation in statistics and education. A popular method, the Mantel-Haenszel (MH) Test, is used for detecting non-uniform differential item functioning (DIF) but ...
Diagnostic Checking For Linearity in Time Series Models
(Applied Statistics, 2020 , Master Thesis)
In this thesis, I studied the well-known portmanteau tests appearing in the time
series literature. In particular, I interest in reviewing the test statistics that can be used
to check the adequacy of the fitted ...
The Impact of Economic Transformations On the Development of the Status of Women in The Arabian Gulf - The Case of Qatar and Bahrain
(Gulf Studies, 2020 , Dissertation)
Neoliberal socio-economic paradigms have become a dominant force in modern societies, including those in the Arabian Gulf region. Their rise has resulted in drastic changes within the role of states towards a focus on the ...
THE EFFECT OF NIOBIUM ON THE PHASE STABILITY AND MECHANICAL PROPERTIES OF NICKEL-BASED HIGH ENTROPY ALLOYS
(Material Science and Technology, 2023 , Master Thesis)
A fundamental understanding of the mechanisms of phase stability of high entropy alloys (HEAs) and the influence of refractory elements is a recent topic of active research. This study investigates the effect of Niobium ...
Exponential model for breast cancer partly interval censored data via multiple imputation
(Applied Statistics, 2021 , Master Thesis)
The estimation problem for interval-censored data has been investigated by several
authors. The application of conventional methods to interval censored data that has been
considered by Lindsey and Ryan (1998) showed ...
Nip/Zno-Doped C3n4 Nanocapsules: A New Highly Corrosion-Resistant Electroless-Plated Coating with Superior Mechanical and Antibacterial Properties
(Material Science and Technology, 2021 , Master Thesis)
Carbon nitride (C3N4) nanomaterials has superior mechanical, thermal and
tribological properties, which make them attractive for various applications including
corrosion resistant coatings. In this research, newly ...
Development of Biosurfactants from Indigenous Hydrocarbon-Degrading Bacteria for Enhancing Remediation of Weathered Oily-Soils and Oil Recovery in Qatar
(Environmental Sciences, 2021 , Master Thesis)
Bacterial strains were isolated from highly weathered oil-contaminated sites,
identified, and differentiated based on their gene expression with the use of matrix assisted laser desorption ionization-time of flight mass ...
