In this paper, we perform two-dimensional simulations of cross-flow forward osmosis (FO) membrane modules in the presence of draw and feed channel spacers. For this purpose, the equations corresponding to the conservation of mass, momentum, and convection-diffusion for the mass fraction of solute are solved using a commercial finite volume flow solver. We consider six configurations of channel ...

several novel composite membranes were prepared to separate and recycle amoxicillin from pharmaceutical wastewater via nanofiltration process. the synthesis of these membranes included three stages: 1- preparation of polysulfone ultrafiltration membranes as a support via phase separation process, 2- modification of its surface by interfacial polymerization as a selective layer (polyamide), and ...

In studying horizontal inhomogeneity in the upper ocean we have developed a technique to measure vertical water velocity and the turbulent fluxes of heat and salt with Autonomous Underwater Vehicles (AUV), and constructed the Autonomous Micro-conductivity and Temperature Vehicle (AMTV) to fully test and exploit the technique. AMTV data was gathered at the Surface Heat Balance of the Arctic (SHE...

TCP is the transport protocol used predominantly in the Internet as well as in peer-to-peer networks. However, peerto-peer networks exhibit very different characteristics from those of conventional client-server networks. In this paper, we argue that the unique characteristics of peer-to-peer networks render TCP inappropriate for effective data transport in such networks. Specifically, we motiv...
