Grounds, grounds, and more grounds
SIMULATION, 1965This paper discusses the need for proper grounding of electrical equipment from the standpoint of safe ty and performance. Seventeen diagrams are em ployed to illustrate the most important points. The discussion follows a fundamental vein in illus trating the proper connections of electrical apparatus to specifically avoid ...

When dealing with multiple growth stages, estimates of above-ground biomass (AGB) based on optical vegetation indices (VIs) are difficult for two reasons: (i) optical VIs saturate at medium-to-high canopy cover, and (ii) organs that grow vertically (e.g.,

Ground Emu as a Replacement for Ground Turkey and Ground Beef
Journal of the American Dietetic Association, 1997Abstract LEARNING OUTCOME: To describe the consumer acceptability of ground emu as a low fat substitute for ground turkey and ground beef. A serving (3.5 oz.) of ground turkey or beef can have up to 13g. or 18g. of fat, respectively. To provide lower fat food choices for Americans, producers are developing or offering new products. Emu, a red meat,

Polarimetrie ground-to-ground and ground-to-air channel characterization in forest environment
2017 11th European Conference on Antennas and Propagation (EUCAP), 2017The precise localization of an injured person in a forest environment can be made owing to his cell phone by deploying a dedicated direction finding equipment in the search zone and placed onboard either a vehicle or a drone. The localization accuracy being strongly dependent on the propagation channel characteristics, measurements have been carried ...

The Journal of the Royal Aeronautical Society, 1954
The problems of noise on the ground coming from aircraft on the ground, while still not simple to resolve, are rather less difficult than those associated with noise coming from aircraft in flight. The source of noise—the aeroplane—is no longer travelling rapidly through the air with three degrees of freedom but is either stationary on the ground or ...

Trends in Immunology, 2015
The past ten years have seen great progress in our understanding of cancer in its many forms, the mechanisms that give rise to malignancy and foster its growth, and those that keep it in check. As the importance of the tumor microenvironment has become evident, so has the role of the immune cells that reside therein and those that migrate to the tumor ...
