On July 25, 2012, SBV infection was identified in a cow in Jura Canton in the northwestern, French-speaking region of Switzerland (Romandie) (7). A serologic study conducted in the United Kingdom showed that several cattle and sheep seroconverted for SBV in 2012 (8). However, our data show that SBV survived the winter, when midge numbers decreased. The precise mechanisms of SBV overwintering ar...

There is an increasing need to operate power plants at low load for longer periods of time. When a once-through boiler operates at a sufficiently low load, recirculation is introduced, significantly altering the control structure. This paper illustrates the possibilities for using constrained control to obtain optimal load gradients in the recirculation mode. A model predictive controller is de...

Recovery of brain mitochondrial function was studied following forebrain ischemia induced in rats by common carotid artery occlusion in combination with hypotension caused by bleeding. A reversible insult was induced by 15-min ischemia in fasted animals (hypoglycemic ischemia), and an irreversible one by 30-min ischemia in fed animals (normoglycemic ischemia), the latter procedure causing exagg...

This study considers water use by Canadian manufacturing firms. The estimation of water demands is based on a detailed crosssectional survey of establishment-level observations on water prices, quantities, and expenditures. Industrial water use is modeled as having four components: intake, treatment prior to use, recirculation, and discharge. Average values for the estimated own-price elasticit...

Two landfill bioreactors were operated under aerobic and anaerobic conditions in a thermo-insulated room at a constant temperature of 32 degrees C. Reactors were filled with 19.5 kg of shredded synthetic solid waste prepared according to the average municipal solid waste compositions determined in Istanbul and operated under wet-tomb management strategy by using leachate recirculation. Aerobic ...

Introduction Dynamic susceptibility contrast (DSC) MR perfusion is based on the indicator dilution theorem for non-diffusible tracers.[1,2] A common misconception is that tracer recirculation cannot occur in order to make use of the underlying theory (i.e., analysis of the tracer kinetics must be “firstpass”).[3-13] As a result, there have been a number of approaches suggested for removing trac...

The main objective of this investigation was to design and investigate a radiant panel cooling system on small scale building type (office) under the central Sudan climatic conditions so as to explore the benefits of radiant cooling systems over conventional air conditioning systems (Variable air volume systems). Transient heat conduction of building (finite difference method) was used to evalu...

–The main thrust of the paper is the evaluation of the aero thermodynamic analysis of reentry trajectory. Computational fluid-dynamics results are presented to show the flow field around a blunted cone-flare in hypersonic flow. This is of particularly interest since it features the hypersonic flow around planetary re entry vehicles, the reason between the cone and the flare is particularly crit...

Gallium nitride (GaN) high-electron-mobility transistors (HEMTs) dissipate high power densities which generate hotspots and cause thermomechanical problems. Here, we propose and simulate GaN-based HEMT technologies that can remove power densities exceeding 30 kW/cm at relatively low mass flow rate and pressure drop. Thermal performance of the microcooler module is investigated by modeling both ...

run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
