Paracetamol, [a] or acetaminophen, [b] is a non-opioid analgesic and antipyretic agent used to treat fever and mild to moderate pain. [13] [14] [15] It is a widely available over-the-counter drug sold under various brand names, including Tylenol and Panadol.
Ringelmann smoke charts, 1897. The Ringelmann scale is a scale for measuring the apparent density or opacity of smoke. [1] [2] It was developed by a French professor of agricultural engineering Maximilien Ringelmann of La Station d'Essais de Machines in Paris, who first specified the scale in 1888. [3] [4]
4-Hydroxyacetophenone monooxygenase is an enzyme that transforms piceol into O-acetylhydroquinone. This enzyme is found in Pseudomonas fluorescens. See also ...
The Carr index (Carr's index [1] or Carr's Compressibility Index [2]) is an indicator of the compressibility of a powder.It is named after the scientist Ralph J. Carr, Jr. The Carr index is calculated by the formula =, where is the freely settled bulk density of the powder, and is the tapped bulk density of the powder after "tapping down".
Measuring combination of an automatic refractometer and a density meter as widely used in the flavors and fragrances industry. Today's laboratories do not only want to measure the refractive index of samples, but several additional parameters like density or viscosity to perform efficient quality control.
Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle of this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as the relative ...
[4] [5] [6] It relies on the computation of a nutrient profiling system derived from the United Kingdom Food Standards Agency score. [ 6 ] A Nutri-Score for a particular food item is given one of five color-coded letters, with 'A' (enlarged letter, dark green) as a score indicating excellent nutrient composition, and 'E' (dark orange) as a low ...
A 0.5 McFarland standard is prepared by mixing 0.05 mL of 1.175% barium chloride dihydrate (BaCl 2 •2H 2 O), with 9.95 mL of 1% sulfuric acid (H 2 SO 4). [ 1 ] Now there are McFarland standards prepared from suspensions of latex particles, which lengthens the shelf life and stability of the suspensions.
