· Another is in processing plants, where our work suggests that many plant operators have blind spots in understanding the drivers of yield. By applying new mathematical techniques that look for hidden relationships between second and thirdorder variables, we have found that plant yields of gold, nickel, phosphate, and other processed minerals can often be improved by 3 to 10 percent within ...

The current brake thermal efficiency of advanced internal combustion engines is limited to 50%, and how to further improve the efficiency is a challenge. In this study, a theoretical investigation on engine thermal efficiency was carried out using onedimension simulations based on the first law of thermodynamics. The energy balance was evaluated by varying parameters such as compression .
Most hyperaccumulators are generally slow growers with low plant biomass; this reduces the efficiency of the remediation process . Thus, in order to increase the efficiency of phytoextraction, plants with high growth rate as well as high biomass (, maize, sorghum, and alfalfa) are sometimes used together with metal chelating substances for ...

Open Access journals are the major source of knowledge for young and aspiring generations who are keen in pursuing a career in sciences. This system provides easy access to networks of scientific that contribute their scholarly works to Open Access journals gain remarkable reputation as the research scholarly explore these works extensively.
Removal efficiency = ∑(5)i=3 to 7 / = % (< 99% ) Since the efficiency of removal of particles greater than 10 μm in size is less than the required efficiency of 99% we have to assume a greater inlet velocity so that we get a smaller inlet area and hence a smaller diameter and a higher efficiency. Case II: Assume inlet velocity= 15 m/s
