Utilizing Recycled Polypropylene Fibers as Reinforcement for Concrete Beams by Bendjillali, Khadra

“…The various fiber content ratios tested in this investigation are 0.25, 0.5 and 1%. Based on the results of this study, the presence of recycled PP fibers in concrete decreases its workability; the addition of an adequate superplasticizer to the concrete mix becomes then necessary. …”

Nanoclay compatibilization of phase separated polysulfone/polyimide films for oxygen barrier by Ammar, Ali

“…Thermal decomposition (TGA) measurements of PSF/PI films showed a decrease in thermal stability upon adding C30B due to its surfactant modification, while film mechanical tensile modulus properties improved slightly by adding low concentration of C30B (~ 1 mass%), but higher nanoclay loading decreased tensile strength and elongation at break. …”

Cultivating microalgae in desert conditions: Evaluation of the effect of light‐temperature summer conditions on the growth and metabolism of nannochloropsis qu130 by Jabri, Hareb Al

“…In the Qatar desert the temperature varies widely, typically between 10° and 45 °C There are also wide variations in light intensity, with values of over 1500 μmolhν.m−2s−1 in summer. A study of the effects of these thermal and light fluctuations is therefore essential for large‐scale outdoor production systems, especially during the summer when temperature and light fluctuations are at their highest. …”

CLINICAL AND ECONOMIC IMPACT OF GENETIC AND NON-GENETIC FACTORS ON INR NORMALIZATION IN PRE-OPERATIVE MANAGEMENT OF WARFARIN PATIENTS by ELJILANY, ISLAM AHMED SAYED AHMED

“…To optimize the period of preprocedural warfarin interruption to decrease the incidence of bleeding in case of bridging and the incidence of thromboembolism in case of non-bridging, a study was conducted to determine the influence of CYP2C9, VKORC1, CYP4F2, FII, and FVII genetic polymorphisms and non-genetic factors on INR decline in a cohort of Arabs undergoing a procedure that requires warfarin interruption and developing an algorithm to tailor the duration of warfarin interruption before the procedure. …”

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. …”
