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 ...

Increasing the distance from which an antineutrino detector is capable of monitoring the operation of a registered reactor, or discovering a clandestine reactor, strengthens the Non-Proliferation of Nuclear Weapons Treaty. This report presents calculations of the reactor antineutrino interactions, from both quasi-elastic neutrino-proton scattering and elastic neutrino-electron scattering, in a ...

This article describes the use of biofilm reactors for the production of various chemicals by fermentation and wastewater treatment. Biofilm formation is a natural process where microbial cells attach to the support (adsorbent) or form flocs/aggregates (also called granules) without use of chemicals and form thick layers of cells known as "biofilms." As a result of biofilm formation, cell densi...

This work demonstrates an approach to determine probability of perturbation the axial profile thermal neutron flux in Advanced Test Reactor. The is expected follow a theoretical cosine shape, due minimal use vertically-withdrawn shims. Reactivity normally controlled by rotation Outer Shim Control Cylinders, uniformly affecting at all locations. Reactor routinely accepts for irradiation experime...

Blankets are a difficult problem for fusion engineering design. Because of the complex flow channels, design, production, processing, and accident maintenance blankets all huge challenges traditional water/gas-cooled blankets. bridge heat transfer tritium production. A high-performance blanket with simplified structure is obviously beneficial engineering, safety, economy. In this study, gravity...

I apply Barwise and Seligman’s theory of information flow to understand how sets of signals can carry information. More precisely I focus on the case where the information of interest is not present in any individual signal, but rather is carried by correlations between signals. This focus has the virtue of highlighting an oft-neglected process, viz., the different methods that apply categories...

The flow channel of the fluids in the nuclear reactor core and the heat exchanger is relatively small. In order to understand the two-phase flow phenomena in the narrow channel, many interesting studies have been carried out, for example, mini capillaries (Wong, et al., 1995, Han & Shikazono, 2009), rectangular channels with small gap (Mishima, et al., 1993, Xu, et al., 1999, Hibiki & Mishima, ...

In this study, the effectiveness of two conventional UV reactors in series for the online sterilization of cheese whey was compared to that of a single conventional reactor. The single reactor and the two reactor series were tested at eleven flow rates (5, 10, 15, 20, 25, 30, 35, 40, 50, 60 and 70 mL min ) and five flow rates, (35, 40, 50, 60, 70 mL min ), respectively. 100% destruction efficie...
