difficult to quickly repair and also to construct A new type of solar distillation called a Tubular Solar Still (TSS) was designed by the authors’ group to overcome the disadvantages in the maintenance and management of the still The TSS consists of a transparent tubular cover made of vinyl chloride and a trough inside the cover

Cause, Cost, and Correction Analysis (C3) on 30 bad-actor pumps Over two years, repair costs have been cut by 75 percent, and emissions by 95 percent SWAT-team approach to resolving your bad-actor problem We assemble the appropriate instrumentation, personnel and expertise on a temporary
product refined from crude was lamp oil (kerosene) Because only a fraction of the crude made good lamp oil, refiners had to figure out what to do with the rest of the barrel Diesel, recognizing that the liquid petroleum byproducts might be better engine fuels than coal dust, began to experiment with one of them This fuel change, coupled
