Interpreting and using the dietary references intakes in dietary assessment of individuals and groups.

For individuals, a statistical approach is available to compare observed intakes to the EAR or AI (to assess adequacy), and the UL (to assess risk of excess). A more qualitative assessment of intakes involves comparison directly to the RDA to evaluate adequacy, but this is accurate only if long-term usual intake is known. For groups of people, the ...

Since natural factors cannot explain all of the decline symptoms, researchers have concluded that air pollution is probably involved. Ozone damage, acid deposition, and excess nitrogen deposition have been postulated as possible ...

Efficient SPECT scatter calculation in non-uniform media using correlated Monte Carlo simulation.
1999-08-01

Accurate simulation of scatter in projection data of single photon emission computed tomography (SPECT) is computationally extremely demanding for activity distribution in non-uniform dense media. This paper suggests how the computation time and memory requirements can be significantly reduced. First the scatter projection of a uniform dense object (P(SDSE)) is calculated ...

Heat Measurement during Plasma Electrolysis
2006-01-01

It is important to establish an accurate heat measurement system to confirm the excess heat from the cold fusion phenomenon. During plasma electrolysis, an accurate heat measurement is especially difficult, because the input power is large and it causes significant evaporation of electrolyte and heat loss to the environment from the ...

The determination of trace and ultratrace elements in biological fluids, including urine and serum, by inductively coupled plasma mass spectrometry (ICP-MS) is discussed. Nonspectral interferences and their corrections by external calibration and calibrator addition are discussed in detail. External calibration with internal calibration and dilution is mostly sufficient to correct for encountered ...

Estimates of the global (G), diffuse (D) and direct-beam (I) irradiances at the surface of the earth can be obtained with a single instrument, ''dial'' radiometer. The dial assembly intermittently shades a solid-state sensor on a continual automatic basis. This is a very simple instrument that does not require mechanical adjustments of the ...
