(Mathematics) the exponent indicating the power to which a fixed number, the base, must be raised to obtain a given number or variable. It is used esp to simplify multiplication and division: ifax=M,then the logarithm ofMto the basea(written logaM) isx. Often shortened to:logSee alsocomm...
(SRC). Avobenzone is highly degraded by UV light and normal day light and it will be drastically reduced over time during the course of normal use(4); control degradation studies have shown that 1 hour of sunlight exposure reduces avobenzone absorbance by 36%(4). In buffered aqueous ...
(1). This corresponds to an atmospheric half-life of about 11.8 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). The UV spectrum for an aqueous solution of 2-phenoxyethanol does not show any absorbance above 290 nm(2) which indicates that 2-phenoxyethanol ...
PROBLEM TO BE SOLVED: To provide phosphor particles whose phosphor purity is more improved, and which improves absorbance of excitation light in a material such as a resin dispersed with the phosphor particles such as the encapsulating resin of a light emitting body used for a light-emitting ...
The measurement of optical density is done at maxima of the absorbance spectra as there is less chance of absorbance with the change in wavelength. The optical density measurement is an important method to quantify various parameters like cell concentration, production of biomass etc. ...

Read the absorbance at 340 nm in 5 min and 10 min, respectively. The results were expressed in units of disintegrations per minute per gram tissue. GPa activity was defined by the NADPH production. Assays of liver glycogen and muscle glycogen Liver and muscle glycogen were measured ...
added to stimulate the cells for 6 h. Captopril was used as a positive control. After incubation, the supernatants were removed, washed with PBS, and replaced with fresh medium. The cells were added with 10 µL CCK8 for 2 h in dark, and the absorbance was measured at 450 nm in a ...
The absorbance was detected at 450 nm using a Microplate reader (Tecan, Durham, NC, USA), and the inhibition rate was calculated by the formula:InhibitionRate(%)=(1−AbsorbanceofthetreatedgroupAbsorbanceofthecontrolgroup)×100 2.4. Cell proliferation curve assay, colony formation assay, and ...
One HUT unit is the amount of enzyme that produces a hydrolysate with the same absorbance at 275nm as a solution containing 1.10ug/ml tyrosine in 0.006N HCl. ***Contains a source of Papain which can hydrolyze proteins found in rabbit diets. One Papain unit is defined as that quantity of...
