The effect of the foam covered ocean surface on the passive microwave remote sensing measurements is studied based on the electromagnetic scattering theory. In fomulating an electromagnetic scattering model, we treat the foam as densely packed sticky air bubbles coated with thin seawater coating. The layer of foam covers the ocean surface that has air bubbles. We then use dense media radiative ...

Feasibility of drilling with supercritical carbon dioxide to serve the needs of deep underbalanced drilling operations has been analyzed. A case study involving underbalanced drilling to access a depleted gas reservoir is used to illustrate the need for such a research. For this well, nitrogen was initially considered as the drilling fluid. Dry nitrogen, due to its low density, was unable to ge...

The purpose of this study was to investigate the acute effects of foam rolling on quadriceps isokinetic and isometric force production as well as knee joint range of motion. Twelve healthy, light to moderately physically active college students volunteered for this study. They had different treatments on three separate days. Participants' non-dominant knee joint range of motion (ROM), quadricep...

Dynamic balance has frequently been evaluated by using center of pressure (COP) during stepping movement. COP sway may be greater during stepping on foam rubber, which is a kind of external load. This study aimed to examine the effect of leg-joint angles and COP sway during stepping on a spot in 13 young male adults (mean age 25.6 ± 4.8 years, mean height 170.6 ± 5.2 cm, mean mass 69.1 ± 8.2 kg...

The era of considering carbon dioxide (CO2) as a waste stream has passed. New methods utilising CO2 feedstock are currently the focus extensive research efforts. A fixed-bed reactor containing commercial Cu/ZnO/Al2O3 catalyst washcoated on Cu foam was used for synthesis methanol through direct hydrogenation. Catalytic activity tests in this were conducted at reaction pressures 30 and 50 bar, te...

In the Niger Delta, low oil recovery rates less than 30% results mainly due to production problems such as water coning, wax deposition and high gas/oil ratios. Meanwhile, remaining becomes a good candidate for EOR methods CO2 injection, polymer foam in-situ combustion steam injection. But it stands, practice of these known enhanced is scarce in Nigeria’s Oil Gas industry. However, this project...
