Effects of covid-19 lockdown on physical activity, sedentary behavior, and satisfaction with life in Qatar: A preliminary study by Hermassi, Souhail

“…The largest reduction was detected for the sum parameter all physical activity (minutes per week, ηp2 = 0.67, p < 0.001; MET (metabolic equivalent of task)-minutes/week, ηp2 = 0.69, p < 0.001). Life satisfaction decreased, with the score for “I am satisfied with my life” (ηp2 = 0.76, p < 0.001) decreasing from 28.1 ± 4.81 to 14.2 ± 6.41 arbitrary units (AU). …”

Effects of Climate and Atmospheric Nitrogen Deposition on Early to Mid-Term Stage Litter Decomposition Across Biomes by Kwon, Taeoh

“…The expected changes in macroclimate and N deposition at the global scale by the end of this century are estimated to increase the 12-month mass loss of easily decomposable litter by 1.1-3.5% and of the more stable substrates by 3.8-10.6%, relative to current mass loss. In contrast, expected changes in atmospheric N deposition will decrease the mid-term mass loss of high-quality litter by 1.4-2.2% and that of low-quality litter by 0.9-1.5% in the temperate biome. …”

An experimental study on achieving even-frosting for an air source heat pump using a novel dual-fan outdoor coil by Bai, Xiaoxia

“…The experimental results demonstrated that when using the novel dual-fan outdoor coil in Cases 3, 4 and 7, the heating/frosting duration was lengthened by 23.6%, 34.5% and 46.4%, and the averaged output heating capacity () was increased by 5.5%, 9.5% and 9.6 %, and averaged COP () by 6.7%, 10.5% and 11.1% respectively, and the defrosting frequency was decreased by 33.3% in Case 7,when compared to using the traditional single-fan outdoor coil. …”

Mitigating Cardiotoxicity of Dendrimers: Angiotensin-(1-7) via Its Mas Receptor Ameliorates PAMAM-Induced Cardiac Dysfunction in the Isolated Mammalian Heart by Akhtar, Saghir

“…Herein, we investigated (a) the effect of polyamidoamine (PAMAM) dendrimer generation (G7, G6, G5, G4 and G3) and surface chemistry (-NH2, -COOH and -OH) on cardiac function in mammalian hearts following ischemia-reperfusion (I/R) injury, and (b) determined if any PAMAM-induced cardiotoxicity could be mitigated by Angiotensin-(1-7) (Ang-(1-7), a cardioprotective agent. …”

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. …”
