4) calculating the resultant force of the active earth pressure according to the formula Ea=[a1(a-n1)x1/2+b1x1-cx1]/sin(alpha-delta); 5), calculating the pressure resultant force application point of the active earth pressure according to the formula which is defined as the specification. ...
Growth in fundamental drivers—energy use, economic productivity and population—can provide quantitative indications of the proposed boundary between the Holocene Epoch and the Anthropocene. Human energy expenditure in the Anthropocene, ~22 zetajoules (ZJ), exceeds that across the prior 11,700 years o...
Intermetallic particles exposed at the surface of the part serve as active corrosion site(s). The exemplary conversion coatings described herein contain a non-conductive phase and an electrically conductive phase. Generally, the non-conductive phase may by a typical metal oxide or metal oxide ...
