Analysis of energy requirements in stirred media mills
… a novel, rod shaped grinding media, significant energy savings in ultrafine wet grinding are seen. This is proven to be an effect attributable to the shape of the grinding media, rather than the density of the grinding media. After a comprehensive efficiency analysis of the performance of a range …

Growth and energy requirements of captive Great Blue Herons (Ardea Herodias)
The energy requirements of Great Blue Herons (Ardea herodias) during critical stages of their life-history when food is considered limiting were investigated. The metabolizable energy coefficients (MEC) of herring (Clupea harengus), mackerel (Scomber scombrus) and trout (Oncorhynchus mykiss) when …

Desalination of brackish groundwater in the United States : minimum energy requirements
… no national assessment has been conducted on the energy costs required to make brackish groundwater potable. Because the ionic composition of groundwater varies significantly from location to location, unlike seawater, conducting site-specific analyses of the resource across the U.S. is necessary. …

Energy requirements and productivity of machinery used to harvest herbaceous energy crops
Herbaceous energy crops (miscanthus, switchgrass, and tallgrass prairie) are promising biomass feedstocks, but are difficult to harvest with traditional machinery. Energy required for harvesting novel herbaceous crops was evaluated in both field and laboratory settings. Previous work on harvesting …
