Energy recovery and nutrients recycling from municipal sewage sludge
Published 2020“…The maximum energy recovery (i.e., 59%) and maximum energy return on investment (i.e., 3.5) were obtained at 350 °C and 60 min of holding time. With the increase in HTL reaction time, the concentration of nitrogen in the APL increased (5.1 to 6.8 mg/L) while the concentration of phosphorus decreased (0.89 to 0.22 mg/L); the opposite was observed for the biochar. …”

CLINICAL AND ECONOMIC IMPACT OF GENETIC AND NON-GENETIC FACTORS ON INR NORMALIZATION IN PRE-OPERATIVE MANAGEMENT OF WARFARIN PATIENTS
Published 2021“…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. …”

Structural performance and moment redistribution of basalt FRC continuous beams reinforced with basalt FRP bars
Published 2021“…Seven beams were longitudinally reinforced with BFRP bars, while the remaining three beams were reinforced with conventional steel bars and served as a control. Test results showed that BFRC-RC beams had higher crack widths, mid-span deflections, and strains than steel-RC beams. …”
