Energy conversion of heat from abandoned oil wells to mechanical refrigeration - Transient analysis and optimization by Mohammed Al-Khawaja (17093017)

“…The system advantages lie in its simple, flexible, and low-cost design as well as in its ability to be driven by a low-temperature heat source (as low as 60 °C). …”

Phosphate-solubilizing bacteria-mediated rock phosphate utilization with poultry manure enhances soil nutrient dynamics and maize growth in semi-arid soil by Kashif Khan (2978691)

“…A factorial randomized complete block design with three replications was employed. Changes in soil properties, including pH, electrical conductivity (EC), soil organic matter (SOM), and nutrient dynamics, were assessed. …”

3D printing of circular materials: Comparative environmental analysis of materials and construction techniques by Shoukat Alim Khan (14778226)

“…The main environmental "hot spot" identified for the geopolymer-based 3D printed construction process was the amount of electrical energy required for the mechanical processing of waste materials, which was more than 61% of the total GWP impact. In addition to decreasing solid CDW, the developed approach has significant potential for improvement by using more sustainable energy sources and reducing the amount of solid CDW generated.…”

A Modification to Enhance the Survival of the Island FDMA Flap by Adding a Skin Bridge by Salim Al Lahham (16515333)

“…We combined Foucher and Holevich characteristics to design a flap that promises to solve the problem.</p><h3>Methods</h3><p dir="ltr">This is a case series that includes 9 patients where we describe a technique that has the potential to enhance the survival of the first dorsal metacarpal artery (FDMA) flap and decreases the rate of distal necrosis via addition of a 5-mm skin bridge to the pedicle and by avoiding tunneling. …”

Probing deposition temperature effects and computational analysis of DC-sputtered tungsten (W) thin films for CZTS based solar cells by M.I. Hossain (22303861)

“…Later, a novel heterojunction solar cell design incorporating a p-type CZTS absorber layer is analyzed in terms of absorber layer thickness with tungsten metal contact where the metal contact thickness was kept at 100 nm. …”

Trace element composition of size-fractionated suspended particulate matter samples from the Qatari Exclusive Economic Zone of the Arabian Gulf: the role of atmospheric dust by Oguz Yigiterhan (14151006)

“…For several other elements (Cd, Cu, Mo, Zn, and Ca) the excess concentrations present after lithogenic correction are most likely of biogenic/anthropogenic origin. The excess concentrations, relative to average dust, for most elements (except Cd) decreased with distance from the shore, which may be due to differences in biology, currents, proximity to the coast, or interannual processes.…”

Prevalence of polypharmacy and the association with non-communicable diseases in Qatari elderly patients attending primary healthcare centers: A cross-sectional study by Ayman Al-Dahshan (8962568)

“…Females were 1.18 times more likely to have polypharmacy compared to males (95% CI: 1.03–1.34). …”

Glycolytic overload-driven dysfunction of periodontal ligament fibroblasts in high glucose concentration, corrected by glyoxalase 1 inducer by Amal Ashour (6752957)

“…</p><h3>Results</h3><p dir="ltr">In high glucose concentration cultures, there was a ca. twofold increase in cellular MG, cellular protein MG-H1 content and decreased attachment of PDLFs to collagen-I. This was driven by increased hexokinase-2 linked glucose metabolism and related increased MG formation. …”

Correction: Prevalence of polypharmacy and the association with non-communicable diseases in Qatari elderly patients attending primary healthcare centers: A cross-sectional study by Ayman Al-Dahshan (8962568)

“…Females were 1.18 times more likely to have polypharmacy compared to males (95% CI: 1.03–1.34). …”

Understanding the phenomenon of saltwater intrusion sourced from desalination plants at coastal aquifers by Farhat Abbas (5480)

“…In order to design mitigation strategies for avoiding groundwater contamination, this study’s findings may help model groundwater pollution caused by the activities of desalination of seawater, which produces concentrated liquid that intrudes into the coastal aquifer through miscible displacement. …”

Insulin sensitivity variations in apparently healthy Arab male subjects: correlation with insulin and C peptide by Noor Suleiman (5245580)

“…<h3>Introduction</h3><p dir="ltr">Decreased insulin sensitivity occurs early in type 2 diabetes (T2D). …”

Exergames versus self-regulated exercises with instruction leaflets to improve adherence during geriatric rehabilitation: a randomized controlled trial by Peter Oesch (3572426)

“…</p><h3>Methods</h3><p dir="ltr">Design: single center parallel group non-blinded randomized controlled trial with central stratified randomization. …”

Assessment of treatment burden and its impact on quality of life in dialysis-dependent and pre-dialysis chronic kidney disease patients by Asmaa Al-mansouri (16931739)

“…Therefore, treatment-related burden should be considered in CKD management and factors that increase it should be considered when designing healthcare interventions directed to CKD patients.…”

Global fertility in 204 countries and territories, 1950–2021, with forecasts to 2100: a comprehensive demographic analysis for the Global Burden of Disease Study 2021 by Natalia V, Bhattacharjee

“…The reference forecast is our estimate of the most likely fertility future given the model, past fertility, forecasts of covariates, and historical relationships between covariates and fertility. …”
