Sorption of benzene and naphthalene on (semi)-arid coastal soil as a function of salinity and temperature حسب NgueleuS.K.

"…The sorption of naphthalene was not affected by the change in salinity but increased by 18% when the temperature decreased from 35 to 5 �C. A sorption kinetic model was also applied to define the sorption behavior of benzene and naphthalene for the coastal soil collected in Qatar and the best fits were achieved with the Langmuir sorption isotherm.…"

Development of a Mechanistic and Data-Driven Model for Multiphase Flow Leak Detection in Pipeline حسب Barooah, Abinash

"…The effect of different pressure constraints, pipe length, pipe diameter, two-phase fluid rheology, leak diameter, leak location, outlet liquid volume fraction, and flowing liquid hold-up on leak size, pressure, and flow rate is analyzed. Decreasing the liquid fraction in the outlet section of the leak leads to a slight increase (6% average) in the inlet mass flow rate and a significant decrease (50% average) in the outlet mass flow rate for fixed pressure constraints, resulting in an increased leak flow rate, pressure, and density. …"

A dynamic MOPSO algorithm for multiobjective optimal design of hybrid renewable energy systems حسب Sharafi, Masoud

"…Additionally, the set coverage metric value shows that at least 67% of Pareto solutions obtained by DMOPSO dominate the solutions resulted by other reported algorithms. By using a sensitivity analysis for the case study, it is found that if the PV panel and wind turbine capital cost are decreased by 50%, the total NPC of the system would be decreased by 18.8 and 3.7%, respectively.…"
