Five different time periods, namely 1982, 1992, 2002, 2013, and 2018, were analysed to determine ... -
Assessment of the Neutralizing Antibody Response of BNT162b2 and mRNA-1273 SARS-CoV-2 Vaccines in Naïve and Previously Infected Individuals: A Comparative Study
( MDPI , 2022 , Report)The currently authorized mRNA COVID-19 vaccines, Pfizer-BNT162b2 and Moderna-mRNA-1273, offer great promise for reducing the spread of the COVID-19 by generating protective immunity against SARS-CoV-2. Recently, it was ... -
Assessment of the Risk of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Reinfection in an Intense Reexposure Setting
( NLM (Medline) , 2021 , Article)BACKGROUND: Risk of reinfection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is unknown. We assessed the risk and incidence rate of documented SARS-CoV-2 reinfection in a cohort of laboratory-confirmed ... -
Assessment of water bodies of united arab emirates coastal sabkhas as potential sites for natural salinity gradient solar ponds
( ASCE - American Society of Civil Engineers , 2008 , Article)Increasing population and growing demands from both agriculture and industry in the United Arab Emirates (UAE) necessitate the need to provide inexpensive fresh water. The only feasible source of such water is desalination. ... -
The association between serum cortisol, thyroid profile, paraoxonase activity, arylesterase activity and anthropometric parameters of undergraduate students under examination stress
( SAGE , 2021 , Article)Stress caused due to examinations during any degree program and at any educational level has been observed at all levels so the present study was conducted to investigate the stress related to final examination in undergraduate ... -
Association between Soft Drink Consumption and Aggressive Behaviour among a Quarter Million Adolescents from 64 Countries Based on the Global School-Based Student Health Survey (GSHS)
( MDPI , 2020 , Article)Soft drink consumption has become a significant public health concern that is associated with various adverse health outcomes.We aim to examine the association between soft drink consumption and aggressive behavior among ... -
Association of Prior SARS-CoV-2 Infection With Risk of Breakthrough Infection Following mRNA Vaccination in Qatar.
( American Medical Association , 2021 , Article)The effect of prior SARS-CoV-2 infection on vaccine protection remains poorly understood. To assess protection from SARS-CoV-2 breakthrough infection after mRNA vaccination among persons with vs without prior SARS-CoV-2 ... -
Association of Serum Vitamin D level and COVID-19 infection: A Case-control Study
( HBKU Press , 2022 , Article)Background: Vitamin D is considered a potent modulator of the immune system, albeit its role in COVID-19 infection is a matter of debate. The present study aimed to estimate the association between serum vitamin D levels ... -
Association of single nucleotide polymorphisms with dyslipidemia and risk of metabolic disorders in the State of Qatar
( Wiley-Blackwell , 2023 , Article)Background: Dyslipidemia is recognized as one of the risk factors of cardiovascular diseases (CVDs), type 2 diabetes mellitus (T2DM), and non-alcoholic fatty liver disease (NAFLD). Objective: The study aimed to investigate ... -
Associations of plant functional diversity with carbon accumulation in a temperate forest ecosystem in the Indian Himalayas
( Elsevier B.V. , 2019 , Article)Carbon accumulation is the capacity of the forest to store carbon in trees, litter and soil, together contributing to climate regulation. Plants differ in their potential to capture, store and release carbon. Consequently, ... -
Asymptotic behaviour of contraction non-autonomous semi-flows in a Banach space: Application to first-order hyperbolic PDEs
( Elsevier Ltd , 2016 , Conference Paper)The asymptotic behaviour is studied for a class of non-autonomous infinite-dimensional non-linear dissipative systems. This is achieved by using the concept of contraction semi-flow, which is a generalization of contraction ... -
Asymptotic formulae for eigenvalues and eigenfunctions of q-Sturm-Liouville problems
( WILEY-VCH Verlag , 2011 , Article)We investigate the asymptotic behavior of the eigenvalues and the eigenfunctions of q-Sturm-Liouville eigenvalue problems. For this aim we study the asymptotic behavior of q-trigonometric functions as well as fundamental ... -
Asymptotic freedom, dimensional transmutation, and an infrared conformal fixed point for the ? -function potential in one-dimensional relativistic quantum mechanics
