Immobilized enzymatic reactors recently have drawn much attention because of the striking advantages, such as high substrate turnover rate and ease in coupling with the separation and detection systems. Carrier materials, which have great effects on the development of the immobilized enzymatic reactors, have always being the focus of study. In this paper, the contributions, mainly in the last 5...

The objective of this study was to characterize the morphology, size-distribution, concentration and genome size of virus-like particles (VLPs) in two acetate-fed Methanosaeta-dominated reactors to better understand the possible correlation between viruses and archaeal hosts. The study reactors were dominated by a single genus of acetoclastic methanogen, Methanosaeta, which was present at 6 to ...

The performance of an anaerobic digestion fed with waste activated sludge (WAS) pretreated with NaOH was examined. The sludge was periodically collected from a municipal wastewater-treatment plant. The laboratory work was run in four 1-1 semi-continuous anaerobic digestion reactors. Reactor A was fed with untreated WAS at 1% total solids (TS). The other three reactors, B, C and D, were respecti...

Aim: To determine the prevalence of tuberculosis among traditional milking cows in southern Zambia and isolation of Mycobacterium spp from the tuberculin positive cow's milk. Materials and Methods: A total of 1,025 cows originating from traditional cattle sector, in Mapepe, Magoye, Monze, Batoka, GARTBatoka, Kalomo areas of Zambia, supplying major quantity of milk to milk processors, were teste...

Catalytic membrane reactors which carry out separation and reaction in a single unit are expected to be a promising approach to achieve green and sustainable chemistry with less energy consumption and lower pollution. This article presents a review of the recent progress of dense ceramic catalytic membranes and membrane reactors, and their potential applications in energy and environmental area...

Monolithic fuels are the most promising candidate for a next generation of high-density research reactor fuels. If successfully developed, the remaining HEU-fueled reactors in the world could presumably be converted to low-enriched fuel — and the use of highly enriched uranium in the civilian nuclear fuel cycle eventually terminated. The most challenging type of reactors to convert are single e...

In the first and second stage nuclear program of Department of Atomic Energy (DAE), technologies are matured for Pressurised Heavy Water Reactors (PHWRs) and Sodium-Cooled Fast Breeder Reactors (FBRs). Pre-service-Inspection (PSI), In-Service-Inspection (ISI) and Post-Irradiation-Examination (PIE) procedures are carried out for mechanical components and structures/assemblies of these reactors, ...

A mathematical model for anaerobic digestion in plug-flow reactors is proposed on the basis of mass balance considerations. The consists a system parabolic partial differential equations variables representing concentrations bio-components constituting waste matrix and takes into account convective diffusive phenomena. reactor modelled as one-dimensional domain; moves direction axis undergoes p...

Nuclear reactors are one of the most intense, pure, controllable, cost-effective and well-understood sources of neutrinos. Reactors have played a major role in the study of neutrino oscillations, a phenomenon that indicates that neutrinos have mass and that neutrino flavours are quantum mechanical mixtures. Over the past several decades, reactors were used in the discovery of neutrinos, were cr...
