* Specific absorption rate

Specific absorption rate ( SAR ) is a measure of the rate at which energy is absorbed by the body when exposed to a radio frequency ( RF ) electromagnetic field ; although, it can also refer to absorption of other forms of energy by tissue, including ultrasound.

Since then, " many cases of seizures triggered by VGs were reported, not only in photosensitive, but also in nonphotosensitive children and adolescents with epilepsy ..... Specific preventive measures concerning the physical characteristics of images included in commercially available VGs ( flash rate, choice of colors, patterns, and contrast ) can lead in the future to a clear decrease of this problem.

The ELA can be used, along with the Specific Infiltration Rate ( s ) derived using the LBNL infiltration model, to determine airflow rate through the building envelope throughout the year.

The rate at which radiation is absorbed by the human body is measured by the Specific Absorption Rate ( SAR ), and its maximum levels for modern handsets have been set by governmental regulating agencies in many countries.

* Specific growth rate, a biology concept

Specific activity is equal to the rate of reaction multiplied by the volume of reaction divided by the mass of total protein.

Conversely, factors that favor plate columns are: presence of solids in feed, high liquid rates, large column diameters, complex columns, columns with wide feed composition variation, columns with a chemical reaction, absorption columns, columns limited by foundation weight tolerance, low liquid rate, large turn-down ratio and those processes subject to process surges.

The rate of skin absorption is also low for inorganic lead.

Therefore, when the numbers of atoms in the ground and excited states are equal, the rate of stimulated emission is equal to the rate of absorption for a given radiation density.

The rate of omeprazole absorption is decreased by concomitant food intake.

However when a population inversion is present the rate of stimulated emission exceeds that of absorption, and a net optical amplification can be achieved.

The rate of absorption is thus proportional to the number of atoms in the lower state, N < sub > 1 </ sub >.

Due to the Doppler effect, the rotation rate of a star affects the width of the absorption lines in the spectrum.

Ultramarine was only used for frescoes when it was applied " secco " because fresco's absorption rate made its use cost prohibitive.

The multiple physical phases in the intestinal tract slow the rate of absorption compared to that of the suspension solvent alone.

During absorption, water must be absorbed at a rate commensurate with the absorption of solutes.

Wheat and maize but not oats modify glucose absorption, the rate being dependent upon the particle size.

The reduction in absorption rate with guar gum may be due to the increased resistance by viscous solutions to the convective flows created by intestinal contractions.

If the rate of absorption is best in the large intestine or colon, then a coating that is acid resistant and dissolves slowly would be used to ensure it reached that point before dispersing.

Dosage is based on the size of the patch, since the transdermal absorption rate is generally constant at a constant skin temperature.

The 800 nm – 980 nm units have a high absorption rate for hemoglobin and thus make them ideal for soft tissue applications, where good hemostasis is necessary.

* The rate of electromagnetic radiation emitted at a given frequency is proportional to the amount of absorption that it would experience by the source.

* The Doppler rotation rate in the Sun ( measured from Doppler-shifted absorption lines ), can be approximated as:

Several factors affect the ability of a teratogen to contact a developing conceptus, such as the nature of the agent itself, route and degree of maternal exposure, rate of placental transfer and systemic absorption, and composition of the maternal and embryonic / fetal genotypes.

The surfactant must enable a fast rate of polymerization, minimize coagulum or fouling in the reactor and other process equipment, prevent an unacceptably high viscosity during polymerization ( which leads to poor heat transfer ), and maintain or even improve properties in the final product such as tensile strength, gloss, and water absorption.

Though not studied quantitatively, the physical properties of liquid elemental mercury limit its absorption through intact skin and in light of its very low absorption rate from the gastrointestinal tract, skin absorption would not be high.

The SAR value is then measured at the location that has the highest absorption rate in the entire head, which in the case of a mobile phone is often as close to the phone's antenna as possible.

Australian research conducted in 2009 by subjecting in vitro samples of human spermatozoa to radio-frequency radiation at 1. 8 GHz and specific absorption rates ( SAR ) of 0. 4 to 27. 5 W / kg showed a correlation between increasing SAR and decreased motility and vitality in sperm, increased oxidative stress and 8-Oxo-2 '- deoxyguanosine markers, stimulating DNA base adduct formation and increased DNA fragmentation.

One of the features promoted, was that the magnesium material used for the casing, as well as the form factor, resulted in an exceptionally low specific absorption rate ( SAR ) for the handset.

Another notable fact about this phone is its very low SAR ( specific absorption rate ) of 0. 33, making it # 10 on the CNET's list of ten lowest-radiation cell phones as of 2005.

The rate will then quicken to a point where the SAR converges towards the price.
