a microporous bisphenol a diglycidyl ether (dgeba) epoxified-polyethersulfone (pes) blend membrane (epes membrane) was prepared through dry-wet phase inversion. this study attempts to correlate the changes in membrane physical and chemical properties when the epes membranes were exposed to different durations of dry-phase inversion, towards the separation efficiency of carcinogen chromium (vi)....

Wind energy is one of the renewable resources which clean and sustainable wind turbine used for harnessing from wind. The blades are key components a to convert into rotational energy. Recently, wingtip devices in horizontal axis (HAWT), decreases vortex drag, while increases lift thereby improve performance turbine. In present study, winglet at tip an NREL phase VI blade. Solidworks, Pointwise...

The NREL PVWatts R © calculator is a web application developed by the National Renewable Energy Laboratory (NREL) that estimates the electricity production of a gridconnected photovoltaic system based on a few simple inputs. PVWatts combines a number of sub-models to predict overall system performance, and includes several built-in parameters that are hidden from the user. This technical refere...

The idea of improving the energy output for small wind turbines without compromising remaining aspects technology, such as costs and structural integrity, is very appealing in context growing concern global warming goal providing electricity to remote isolated regions. This work aims contribute development distributed generation by exploring effects bend–twist coupling on performance a turbine ...

The IEA Wind Task 30 OC4 (Offshore Code Comparison Collaboration Continuation) project was a continuation of the OC3 project of IEA Wind Task 23 Subtask 2, and was initiated due to the strong interest in continuing the work of OC3. The purpose of the project was to perform a benchmarking exercise of offshore wind turbine dynamics codes. OC4 consisted of two phases that were not considered in OC...

artificial neural networks (anns) are computer techniques that attempt to simulate the functionality and decision-making processes of the human brain. in the past few decades, artificial neural networks (anns) have been extensively used in a wide range of engineering applications. there are only a few applications in liquid membrane process. the objective of this research was to develop artific...

the role of vi-capsular polysaccharide (vi-cps) in human immunity against infection caused by salmonella typhi is well known. the downstream process of purification generally causes depolymerization of vi-cps to a nonimmunogenic low molecular weight form. in the present study, a standard strain of sal. typhi ty6s was grown under submerge cultural conditions in a pilot-plant scale of 90 liter fe...
