Small volume operation and rapid thermal cycling have been subjects of numerous reports in micro reactor chip development. Sensitivity aspects of the micro PCR reactor have not been studied in detail, however, despite the fact that detection of rare targets or trace genomic material from clinical and/or environmental samples has been a great challenge for microfluidic devices. In this study, a ...

A bench-scale up-flow anaerobic sludge blanket (UASB) reactor was applied to start-up the anaerobic ammonium oxidation (Anammox) process from conventional return activated sludge. The reactor was operated for approximately 170 days and was fed synthetic wastewater containing mainly nitrite ) (NO2 − and ammonium ) (NH 4 + as main substrates. After 106 days of operation, the first evidence of Ana...

The Nigeria Research Reactor-1 (NIRR-1) is the nation’s first nuclear reactor and it is sited at the Centre for Energy Research and Training, Ahmadu Bello University, Zaria, Nigeria. It is a Miniature Neutron Source Reactor (MNSR) that attained criticality on February 03, 2004 and was licensed to operate at a maximum power of 31 kW three days a week in June 01, 2004. This presentation enumerate...

X $EVWUDFW In this study the partial oxidation of Q-butane to maleic anhydride (MA) in a solid electrolyte membrane reactor (SEMR) was investigated experimentally. The electrical conductivity of solid electrolyte membrane materials and vanadium phosphorus oxide (VPO) catalyst was investigated with 2-probe impedance spectroscopy. 13% yttria stabilized zirconia was selected as the solid electroly...

A mesophilic unsaturated flow (trickle bed) reactor was designed and tested for H2 production via fermentation of glucose. The reactor consisted of a column packed with glass beads and inoculated with a pure culture (Clostridium acetobutylicum ATCC 824). A defined medium containing glucose was fed at a flow rate of 1.6 mL/min (0.096 L/h) into the capped reactor, producing a hydraulic retention ...

The Halden Virtual Reality Centre (HVRC) of the OECD Halden Reactor Project aims to provide expertise and an advanced facility for the development of VR-based tools to meet various industry needs. The primary areas of focus are control room design, decommissioning planning, and maintenance and operations training. Both research and development work is performed at the centre, with the ultimate ...

In Korea, the technology of a load fo nuclear power plant has been being developed. automatic controller which is able to control temperature and axial power distribution was automatic controller is functionally divided identification algorithm and a model predictive con former transforms the nuclear reactor status into numerically. And the latter uses them and ge manipulated values such as two...

The paper analyses possible types, shapes and locations of defects in a life cycle according to such factors of a urea reactor as material, structure, manufacture approach, work environment, operating medium and failure mode. Then suitable nondestructive testing methods are chosen to test a urea reactor on service on the basis of characteristics of various nondestructive testing methods. And te...

A short review of batch reactor theory and practice is the subject of this paper. Based on unsteady state mass and energy balances, the mathematical set of equations describing the time-dependent behaviour of a batch or semibatch reactor is reported. The attention is focused on some examples of batch reactor experiences (experimental studies, scale-up techniques, industrial operation and optimi...
