This gene encodes a protein that belongs to the microtubule-associated protein family. The proteins of this family were originally isolated since they copurify with tubulin in polymerization experiments: tubulin in cell extracts can be made to polymerize to produce microtubules (MT) under the influence of heat and the addition of GTP, and the MT can then be collected by centrifugation.
A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.
2,4,6-Tris(dimethylaminomethyl)phenol is an aromatic organic chemical that has tertiary amine and phenolic hydroxyl functionality in the same molecule. [1] The formula is C 15 H 27 N 3 O and the CAS Registry Number is 90-72-2. It is REACH registered and the European Community Number is 202-013-9. [2] [3] [4]
Transaction Capabilities Application Part, from ITU-T recommendations Q.771-Q.775 or ANSI T1.114 is a protocol for Signalling System 7 networks. Its primary purpose is to facilitate multiple concurrent dialogs between the same sub-systems on the same machines, using Transaction IDs to differentiate these, similar to the way TCP ports facilitate multiplexing connections between the same IP ...
As part of the Fit to Fight program, the Air Force adopted a more stringent physical fitness assessment in 2004 and replaced the annual ergo-cycle (stationary bike) test that the Air Force had used for several years. [1] [2] Results are stored in the Air Force Fitness Management System (AFFMS) and accessible via the AF Portal. [3]
Structure of the [Ti 4 F 18] 2-dianion. TiF 4 forms adducts with many ligands. One example is the complex cis-TiF 4 (CH 3 CN) 2, which is formed by treatment with acetonitrile. [6] It is also used as a reagent in the preparation of organofluorine compounds. [7] With fluoride, the cluster [Ti 4 F 18] 2-forms. It has an adamantane-like Ti 4 F 6 ...
Thus, the second partial derivative test indicates that f(x, y) has saddle points at (0, −1) and (1, −1) and has a local maximum at (,) since = <. At the remaining critical point (0, 0) the second derivative test is insufficient, and one must use higher order tests or other tools to determine the behavior of the function at this point.
2,2′-Dipyridyldisulfide, sometimes known as DPS, is used for preparing thiols [1] [2] and activating carboxylic acid for coupling reactions, as in the following ...
