Ionic radius, r ion, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice.
The tables below include tabular lists for selected basic foods, compiled from United States Dept. of Agriculture sources.Included for each food is its weight in grams, its calories, and (also in grams,) the amount of protein, carbohydrates, dietary fiber, fat, and saturated fat. [1]
[2] [3] Ion channels are one of the two classes of ionophoric proteins, the other being ion transporters. [ 4 ] The study of ion channels often involves biophysics , electrophysiology , and pharmacology , while using techniques including voltage clamp , patch clamp , immunohistochemistry , X-ray crystallography , fluoroscopy , and RT-PCR .
In information and communications technology, a media type, [1] [2] content type [2] [3] or MIME type [1] [4] [5] is a two-part identifier for file formats and content formats. Their purpose is comparable to filename extensions and uniform type identifiers , in that they identify the intended data format.
The only writer to comment in detail on the torture of the tablillas may be paraphrased as follows: "The torture of the tablillas is rarely given, the subject trussed up as for the torture of water and cords; having not obtained confession, four palm-sized tablillas are brought, each with five narrow finger-width or toe-width holes, and to give grave pain they hammer a wedge, bit by bit ...
The leaves are paper-thin and small, one measuring 40 by 31 mm (1.6 by 1.2 in) and the other 35 by 30 mm (1.4 by 1.2 in). They had been arranged symmetrically on the woman's chest, with her lips sealed by a gold danake , or " Charon's obol ", the coin that pays the ferryman of the dead for passage; this particular coin depicted the head of a ...
