Experimentally, the absorption coefficient (α) can be calculated from this simple relation: α = 1/t ln [ (1-R)2 / T] where t is the sample thickness, T and R are the transmission and reflection

Drug absorption is determined by the drug’s physicochemical properties, formulation, and route of administration. Dosage forms (eg, tablets, capsules, solutions), consisting of the drug plus other ingredients, are formulated to be given by various routes (eg, oral, buccal, sublingual, rectal, parenteral, topical, inhalational).

Preclinical CRO Absorption Systems partners with pharmaceutical & medical device companies to consistently deliver faster, better results at less cost. 說明 Absorption of the majority of nutrients takes place in the jejunum, with the following notable exceptions: Iron is absorbed in the duodenum. Vitamin B12 and bile salts are absorbed in the terminal ileum. Water and lipids are absorbed by passive diffusion throughout the small intestine. 5 synonyms of absorption from the Merriam-Webster Thesaurus, plus 17 related words, definitions, and antonyms.

Se hela listan på powerlisting.fandom.com Absorption spectroscopy is useful in chemical analysis because of its specificity and its quantitative nature. The specificity of absorption spectra allows compounds to be distinguished from one another in a mixture, making absorption spectroscopy useful in wide variety of applications. absorption the sharing of indirect costs or OVERHEADS to units of product by means of COST RATES.Provided that actual overheads do not exceed BUDGET and that actual output is the same as budgeted output, then the overhead cost rate should allow total product cost to be determined, and a selling price set which will recover the overhead costs involved in producing and selling the product.

Chemische Absorption beschreibt den Prozess der Aufnahme oder des „Lösens“ eines Atoms, Moleküls oder eines Ions in einer anderen Phase. Hierbei handelt es sich nicht um eine Anlagerung an der Oberfläche (), sondern um eine Aufnahme in das freie Volumen der absorbierenden Phase.

I intend to write some text explaining the general process of absorption of sound in air (viscous effects, thermal conduction effects, and molecular relaxation processes). 2020-12-18 Absorption, in wave motion, the transfer of the energy of a wave to matter as the wave passes through it. The energy of an acoustic, electromagnetic , or other wave is proportional to the square of its amplitude— i.e., the maximum displacement or movement of a point on the wave; and, as the wave passes through a substance, its amplitude steadily decreases. Absorption spectroscopy refers to spectroscopic techniques that measure the absorption of radiation, as a function of frequency or wavelength, due to its interaction with a sample.The sample absorbs energy, i.e., photons, from the radiating field.
