Improvement of both lipid and biomass productivities of Qatar Chlorocystis isolate for biodiesel production and food security by Saadaoui, Imen

“…QUCCCM14, which was not previously known as a promising strain. Indeed, culturing QUCCCM14 using f/2 medium with 10× NaH2PO4 (0.15 g L−1 NaNO3 and 5.6 mg L−1 NaH2PO4) resulted in an improvement of 3.178 folds the lipid productivity reaching 56.121 mg L−1 day−1 and enhanced the biomass productivity reaching 141.363 mg L−1 day−1, simultaneously. …”

Unraveling the future productivity burden of cardiovascular disease in Qatar: Investigating the modifiable risk factors control in type 2 diabetes by Abushanab, Dina

“…The financial value of PALYs was determined based on the gross domestic product (GDP) per full-time worker (i.e. US$80,573). The base-case model estimated the productivity burden of CVD, and interventional scenarios were simulated to assess potential gains resulting from improved control of modifiable risk factors, including reduced incidence of T2D, lower systolic blood pressure (SBP), decreased number of smokers, and reduced total cholesterol. …”

Design and analysis of PV fed high-voltage gain DC-DC converter using PI and NN controllers by Madisa V.G., Varaprasad

“…When the converter switch comes under active state two capacitors are discharged in series, similarly when the converter switch under inactive state those two capacitors are charged in parallel through the coupled inductor (CI) energy so, to get a high voltage at the converter output side. To reuse the leakage-inductor (LI) energy of the CI with the help of a passive clamp circuit for reducing the voltage stress across the switch, similarly switch has less resistance so conduction losses also decreased. …”

ASSOCIATION BETWEEN INSULIN RESISTANCE AND NITRIC OXIDE IN HUMAN RETINAL MICROVASCULAR ENDOTHELIAL CELLS IN VITRO by Bushra, Sumbul

“…This study demonstrated that Hyperglycemia causes an increase in ROS/oxidative stress and apoptosis, while insulin promotes a significant decrease in ROS and apoptosis, eNOS mediated NO production increases with hyperglycemia but remarkably reduced with insulin treatment after 1hour, 2 hours and 4 hours. …”

Conversion of Organic Municipal Wastes into Biochars and their Effect on Fertility Parameters of Normal and Sabkha Soils of Qatar by Ahmedna, Mohamed

“…To each pot, sufficient amount of 0.25-mm sieved biochar was mixed with soil to yield carbon to soil ratios of 0, 1, and 2% (wt/wt). Box-Behnken experimental design was used instead of the full factorial to decrease the number of treatments to a manageable level (126 treatments) with three replications at the center. …”

Recycled Polypropylene Fibres for Reinforcing Cement Mortar under Arid Conditions by Bendjillali, Khadra

“…It is also shown that under arid conditions, the presence of 1% of recycled polypropylene fibres in cement mortar leads to a considerable decrease in total shrinkage of about 46% and an increase in the flexural and compressive strength of about 24% and 26%, respectively, compared to control mortar (CM) at the age of 194 days. …”

Kv7 Channel Activators Flupirtine and ML213 Alleviate Neuropathic Pain Behavior in the Streptozotocin Rat Model of Diabetic Neuropathy by Ahmed, Ashraf Ibrahim

“…Single injections of flupirtine (10 mg/kg, i.p.) and ML213 (5 mg/kg, i.p.) to STZ rats (35-days after STZ treatment) caused significant increases in the mean PWT, but not PWL, indicating attenuation of mechanical, but not heat hypersensitivity. …”
