111Dual-energy X-ray absorptiometry — Not to be confused with Bone scan. Dual energy X ray absorptiometry Intervention A scanner used to measure bone density with dual energy X ray absorptiometry. ICD 9 CM …
112Spin density wave — (SDW) and charge density wave (CDW) are names for two similar low energy ordered states of solids. Both these states occur at low temperature in anisotropic, low dimensional materials or in metals that have high densities of states at the Fermi… …
113Nutrient density — The term nutrient density has several meanings. Most commonly, nutrient density is defined as a ratio of nutrient content (in grams) to the total energy content (in kilocalories or joules). Nutrient dense food is opposite to energy dense food… …
114Nuclear density gauge — A nuclear density gauge is a tool used in civil construction and the petroleum industry, as well as for mining and archaeology purposes. It consists of a radiation source that emits a directed beam of particles and a sensor that counts the… …
115Kinetic energy — The kinetic energy of an object is the extra energy which it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its current velocity . Having gained this energy during its acceleration …
116Dual energy X-ray absorptiometry — (DXA, previously DEXA) is a means of measuring bone mineral density (BMD). Two X ray beams with differing energy levels are aimed at the patient s bones. When soft tissue absorption is subtracted out, the BMD can be determined from the absorption …
117Wireless energy transfer — or wireless power is the transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient, hazardous,… …
118Urban density — is a term used in urban planning and urban design to refer to the number of people inhabiting a given urbanized area. As such it is to be distinguished from other measures of population density. Urban density is considered an important factor in… …
119Threshold displacement energy — The threshold displacement energy Td is the minimum kinetic energy that an atom in a solid needs to be permanently displaced from its lattice site to a defect position. It is also known as displacement threshold energy or just displacement energy …
120Low-energy ion scattering — LEIS redirects here; for the Hawaiian garland see Lei (Hawaii). Low energy ion scattering spectroscopy (LEIS), sometimes referred to simply as ion scattering spectroscopy (ISS), is a surface sensitive analytical technique used to characterize the …
