Algal-algal bioflocculation enhances the recovery efficiency of Picochlorum sp. QUCCCM130 with low auto-settling capacity by Saadaoui, I.

“…Results showed that self-settlement capacity increased with cell size and can be indirectly related to a decreased zeta potential of larger cells which enhances the Van der Waals attractive forces. …”

Molecular dynamics of CH4/CO2 on calcite for enhancing gas recovery by Carchini, Giuliano

“…In fact, from pure methane to 20/80 CO2/CH4, methane adsorption increases linearly with pressure. For gas mixtures with a CO2 concentration higher than 40%, higher pressure has less impact on methane adsorption. …”

Mobile Epifauna Associated To Artificial Substrates In Offshore Qatari Waters by Abdulaziz Aziz, Naeem

“…Multivariate analysis for abundance and biomass showed that both Site and Depth, as well as their interaction, had significant effects on the mobile macrofaunal community. A general trend of total abundance and average number of taxa decreasing with depth was observed, although with some notable exceptions. …”

Experimental results and modelling of corrosion-damaged concrete beams strengthened with externally-bonded composites by Elghazy M.

“…The FE models were able to capture the non-linear behavior of the strengthened beams. The interfacial bond stress-slip models at the fabric/matrix and composite/concrete interfaces and the number of composite layers had the most significant impact on the predicted response of the strengthened beams whereas the corrosion level, modeled as a reduction in the steel reinforcement cross-section, showed a slight effect on their performance. …”

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). …”

High temperature thermal stability of innovative nanostructured thin coatings for advanced tooling by Cabibbo, Marcello

“…The main problem with steel, isthat itexhibits a relatively low hardness (below 10 GPa) which strongly decreases upon annealing above about 600 K.Thus, the majority of modern tools are nowadays coated with hard coatings that increase the hardness, decrease the coefficient of friction and protect the tools against oxidation. …”
