Power management in multiuser adaptive modulation transmission under QoS requirements by Althunibat, Saud

“…The obtained results are encouraging as they show a great decrease in the system power budget. The multiuser system capability is also exploited to achieve larger power saving values and smaller probability of power outage by scheduling the user with the best channel characteristics at each time instant. …”

Pilot-scale petroleum refinery wastewaters treatment systems: performance and microbial communities' analysis by Karray, Fatma

“…The reduction of the COD, BOD5, phenols, and the total petroleum hydrocarbon (TPH) reached 82.10%, 85.87%, 91.63%, and 81.11%, respectively at high hydraulic residence time (HRT = 10 days). Decreasing HRT to 5 and 2.5 days led to a decrease in the efficiency of the process and a decrease in biomass concentration was also observed (<1000 mg/l). …”

Investigation of the effect of polyelectrolyte structure and type on the electrokinetics and flocculation behavior of bentonite dispersions by Shaikh S.M.R.

“…The reduction in the dispersion turbidity and negative zeta potential is considerably greater in the presence of cationic PAMs than anionic and amphoteric PAMs, due to an increased adsorbed layer thickness of cationic PAMs. In addition, the adsorption studies showed a higher bentonite surface affinity for cationic PAMs than anionic and amphoteric PAMs. …”

SARS-CoV-2: An Analysis of the Vaccine Candidates Tested in Combatting and Eliminating the COVID-19 Virus by Elmancy, Laila

“…Even though research has progressed the understanding of the SARS-CoV-2 virus, the information gathered about the vaccine trials and their findings have been scarcely distributed to the public in a single study. The information available to scientists has therefore given researchers a pathway to building an efficacious vehicle to substantially decrease the spread of the virus. …”
