Renewable Energy Consumption and Carbon Emissions: Evidence from an Oil-Rich Economy by Shahriyar Mukhtarov (19325662)

“…According to the findings, a 1% increase in renewable energy consumption leads to a 0.26% decrease in consumption-based CO₂ emissions, while a 1% rise in real GDP per capita leads to a 0.46% rise in consumption-based CO₂ emissions. …”

An atomistic molecular dynamic model to study the properties of LLDPE and wax by M. F. T. Mosoabisane (17725950)

“…The chain length of the wax showed no relationship to the solubility parameter in the solid state or in the melt. There was a decrease in the solubility parameter of the modelled LLDPE with an increase in temperature. …”

Formation of Trihalomethanes during Seawater Chlorination by Ahmed Abdel-Wahab (1748986)

“…Chlorination of seawater has shown significant increase in total THMs (TTHMs) and in bromoform concentrations. Rapid decrease of UV absorbance at 254 nm was also observed during seawater chlorination which is indicative of natural organic matter degradation into small organic molecules including THMs and other by-products. …”

Structural and physical properties of the dust particles in Qatar and their influence on the PV panel performance by Brahim Aïssa (14157243)

“…However, even when these characteristics have been addressed appropriately, there are other factors that adversely affect the performance of PV systems, namely the temperature-induced voltage decrease leading to a PV power loss and the dust accumulation (soiling). …”

Stability and thermophysical properties test of carbide-derived carbon thermal fluid; a comparison between functionalized and emulsified suspensions by Ismail W. Almanassra (14151321)

“…The results demonstrated that the thermal conductivity enhancement was independent of temperature, decreases with gum-Arabic concentration, and significantly enhanced with CDC loading with a maximum enhancement of 26.1% for 0.3 wt% functionalized CDC. …”

Solar hydrogen production via thermochemical magnesium oxide – Magnesium sulfate water splitting cycle by Rahul R. Bhosale (6467102)

“…Overall analysis confirms that although the rise in the molar flow rate of Ar from 1 to 50 mol/s results in a decrease in the thermal reduction temperature from 1490 K to 1282 K, the solar-to-fuel energy conversion efficiency is adversely affected and reduces from 47.7% to 18.1%. …”

Global pattern, trend, and cross-country inequality of early musculoskeletal disorders from 1990 to 2019, with projection from 2020 to 2050 by Yingzhao, Jin

“…MethodsThe global prevalence, years lived with disabilities (YLDs), disability-adjusted life years (DALYs), projection, and inequality were estimated for early MSK diseases, including rheumatoid arthritis (RA), osteoarthritis (OA), low back pain (LBP), neck pain (NP), gout, and other MSK diseases (OMSKDs). …”

Diabetes-related cardiovascular and economic burden in patients hospitalized for heart failure in the US: a recent temporal trend analysis from the National Inpatient Sample by Menatalla Mekhaimar (14103708)

“…In patients with HF and DM, mean (SD) age slightly decreased from 71 (13) to 70 (13) years, in which 47.5% were males in 2005 as compared with 52% in 2014 (p trend < 0.001 for both). …”

Maternal Body Mass Index and Recommended Gestational Weight Gain in a Middle Eastern Setting by Tawa Olukade (11619453)

“…In line with IOM recommendations, we found that higher BMI was correlated with decreased GWG and BMI was significantly associated with GWG even after adjusting for maternal age, parity, and infants’ gestational age at birth. …”

Fluid-Structure-Acoustic coupling analysis for external laminar and turbulent fluid flows by Tohid Adibi (17871551)
