Followed by a review of previous studies of magnetohydrodynamic (MHD) duct flows in a non-uniform magnetic field at the entry into a magnet (fringing magnetic field), the associated MHD problem is revisited for a particular case of a nonconducting rectangular duct of a small aspect ratio ε = b/a (here, b is the duct half-width in the magnetic field direction, and a is the half-height). The sugg...

Six advanced reactor concepts have been selected for Generation-IV reactors and are being investigated worldwide to meet the challenging goals of effective resource utilization and waste minimization (sustainability), improved safety, enhanced proliferation resistance, and reduced system cost. [1] The six systems are very high temperature reactor (VHTR), sodium-cooled fast reactor (SFR), superc...

Gartner’s cyst accounts for 11% of all vaginal cysts. It results from total or partial occlusion duct, the mesonephric duct remainder. is often located in anterior lateral wall vagina cervix to introitus, however it has exceptionally been described posterior location also.It typically small and asymptomatic occurs along walls vagina, following course duct. Rarely can be congenital., ,

the down-flow hanging sponge (dhs) reactor, which was developed for post-treatment of effluent from up-flow anaerobic sludge blanket (uasb) process treating sewage, uses polyurethane sponge as media to retain biomass. wastewater is trickled from the top of the reactor and purified by microorganisms retained both inside and outside of the sponge media as the wastewater flows vertically down thr...

anaerobic digestion of organic solid waste (osw) from kitchen was conducted in completely stirred tank reactors (cstrs) under both mesophilic and thermophilic conditions. the lab-scale reactors were fed with the osw containing 10% of total solids (ts) at a hydraulic retention time (hrt) of 30 days (3.0-3.5 g-ts/l/d of volumetric loading rate). both mesophilic and thermophilic reactors exhibited...

India's nuclear power program is based on indigenous materials and technology, with the potential for providing energy security for many centuries. This paper examines the technical validity of this plan, specifically the role of breeder reactors for extending the domestic uranium supplies. Our study shows breeding is unlikely to occur at anywhere near the rates envisioned, leading to a slow gr...

The current regulations for nuclear power plants focus on light water reactors (LWRs), and as such they may not be properly applied to non-LWR reactors such as Generation IV Reactors. For instance, there is no plant state comparable to core damage in pebble bed reactors [1]. As a result, the surrogate safety goal based on core-damage frequency (CDF), as being applied to LWRs in many countries d...

We report a study of the continuous generation of polymer particles in parallel multiple modular microfluidic (M3) reactors. Each module consisted of sixteen parallel microfluidic reactors comprising emulsification and polymerization compartments. We identified and minimized the effects of the following factors that could result in the broadening of the distribution of sizes of the particles sy...

The performance of the ANAMMOX process was investigated in two identical laboratory-scale multi- and single-fed upflow anaerobic sludge blanket (UASB) reactors (denoted R1 and R0) at different hydraulic residence times (HRTs) varying from 2.06 to 1.52 h and NH4(+)-N inf concentrations ranging from 70 to 266 mg L(-1). The substrate removal efficiencies of both reactors decreased as HRT decreased...
