Chain Reaction is an American television game show created by Bob Stewart, in which players compete to form chains composed of two-word phrases. The show has been revived four times. Bill Cullen hosted the original series on NBC from January 14, 1980 to June 20, 1980.
TRiC, the eukaryotic chaperonin, is composed of two rings of eight different though related subunits, each thought to be represented once per eight-membered ring. TRiC was originally thought to fold only the cytoskeletal proteins actin and tubulin but is now known to fold dozens of substrates.
Initiation: The reaction is started by a free-radical source which may be a decomposing radical initiator such as AIBN. In the example in Figure 5, the initiator decomposes to form two fragments (I•) which react with a single monomer molecule to yield a propagating (i.e. growing) polymeric radical of length 1, denoted P 1 •.
The technique is so named because the second number in a pair of successive years becomes the first in the next pair. The result is a continuous "chain" of weights and averages. [3] The advantage of using the chained-dollar measure is that it is more closely related to any given period covered and is subject to less distortion over time.
This summer, Dollar Tree rolled out a new program enabling the discount retail chain to sell items costing as much as $5. Dollar Tree Plus, as it is called, follows an across-the-board price ...
The discount chain said over 300 items will see price points from $1.50 to $7 this year as part of its “multi-price expansion ... were offset by a 1.2% drop in sales at Family Dollar stores ...
Levinthal's paradox is a thought experiment in the field of computational protein structure prediction; protein folding seeks a stable energy configuration. An algorithmic search through all possible conformations to identify the minimum energy configuration (the native state) would take an immense duration; however in reality protein folding happens very quickly, even in the case of the most ...
The mechanism of homogeneous ring-opening metathesis polymerization is well-studied. It is similar to any olefin metathesis reaction. Initiation occurs by forming an open coordination site on the catalyst. Propagation happens via a metallacycle intermediate formed after a 2+2 cycloaddition. When using a G3 catalyst, 2+2 cycloaddition is the ...
