In this experimental study, graphene oxide-blended glass-filled nylon (GO-GFN) hybrid nanopolymer composites were developed and characterized. Transmission electron microscopic studies performed to study the dispersion of oxide in composites. Dynamic mechanical analysis thermogravimetric analyses conducted on fabricated analyze thermal stability. Mechanical properties investigated by tensile te...

In this study, we identified and characterized the hydrographic attributes related to the success of recruitment of migratory fishes in the Upper Paraná River floodplain. To achieve our objectives, we analyzed inter-annual variations in the abundance of young-of-the-year (YOY; index of recruitment) of six migratory species and their relations with hydrographic attributes. Recruitment was relate...

Soil organic phosphorus (SOP) can greatly contribute to plantavailable P and P nutrition. The study was conducted to determine the effects of organic amendments on organic P fractions and microbiological activities in paddy soils. Samples were collected at the Changshu Agro-ecological Experiment Station in Tahu Lake Basin, China, from an experiment that has been performed from 1999 to 2004, on ...

Surfactant-based oil recovery processes are employed to lower the interfacial tension in immiscible displacement processes, change wettability of rock a more water-wet system and emulsify displace it subsurface porous media. Furthermore, these phenomena can reduce capillary pressure enhance spontaneous imbibition. The key factors affecting such process temperature, salinity pH fluids, surfactan...

In order to determine the matching relationship of polymer molecular weight and reservoir permeability in ASP (alkaline/surfactant/polymer) flooding, a number of core flooding experiments with different polymer molecular weights are performed. Two types of curves for the relationship between the pressure difference and the injection pore volume multiples are obtained. One describes the characte...
