Most of the previous diagnostics research for vapor compression equipment has been performed for packaged air conditioners and chillers. This paper describes application of a decoupling-based diagnostic technique that was originally developed for air conditioners to equipment used in walk-in coolers and freezers. Testing was performed on a small, restaurant-style walk-in cooler and a small walk...
Abstract An experiment was conducted to compare the unsaturated hydraulic conductivity (K) calculated by Jackson equation and van Genuchten for soils different in gypsum content treated with some soil conditioners. Two were used, gypsiferous (410 gm kg-1gypsium) clayey (435 kg-1 clay), mixed three levels 0, 50, 100%. The peat moss 0 and1%, polymer,0,1.and 2% without addition. Then, packed into ...
In urban areas of low-income countries, treatment of faecal sludge (FS) is insufficient or non-existent. This results in large amounts of FS being dumped into the environment. Existing treatment technologies for FS, such as settling-thickening tanks and drying beds, are land intensive which is limiting in urban areas. Enhanced settling and dewatering by conditioning was evaluated in order to re...
A current debate exists as to whether locomotion on foot is guided by optic flow (the apparent motion of the world when the subject is moving) [1–4] or perceived direction [5]. Rushton et al. [5] have shown that the path taken by a participant wearing prism spectacles is described reasonably by a model predicting trajectory from visual direction. We repeated Rushton et al.’s [5] experiment but ...
