Transfer agents keep records of who owns a company's stocks and bonds and how those stocks and bonds are held—whether by the owner in certificate form, by the company in book-entry form, or by the investor's brokerage firm in street name.
A message transfer agent receives mail from either another MTA, a mail submission agent (MSA), or a mail user agent (MUA). The transmission details are specified by the Simple Mail Transfer Protocol (SMTP).
Deposit and withdrawal Supporting deposits and withdrawals involves the relationship between the transfer agent and/or issuers and the CSD. It also covers the CSD's role within the underwriting process or listing of new issues in a market.
In chemistry, a phase-transfer catalyst or PTC is a catalyst that facilitates the transition of a reactant from one phase into another phase where reaction occurs.
In chemistry, transfer hydrogenation is a chemical reaction involving the addition of hydrogen to a compound from a source other than molecular H 2. It is applied in laboratory and industrial organic synthesis to saturate organic compounds and reduce ketones to alcohols, and imines to amines.
Chain transfer from polypropylene to backbone of another polypropylene. Transfer to solvent. In solution polymerization, the solvent can act as a chain transfer agent. Unless the solvent is chosen to be inert, very low molecular weight polymers can result.
It makes use of a chain-transfer agent (CTA) in the form of a thiocarbonylthio compound (or similar, from here on referred to as a RAFT agent, see Figure 1) to afford control over the generated molecular weight and polydispersity during a free-radical polymerization.
Transfer agents provide a variety of services to issuing companies, including: maintaining a registry of all shareholders, paying dividends and conducting proxy campaigns.
The general mechanism for methyl transfer is a S N 2-like nucleophilic attack where the methionine sulfur serves as the leaving group and the methyl group attached to it acts as the electrophile that transfers the methyl group to the enzyme substrate.
An e-mail agent is a program that is part of the e-mail infrastructure, from composition by sender, to transfer across the network, to viewing by recipient. The best-known are message user agents (MUAs, aka, e-mail clients) and message transfer agents (MTAs, programs that transfer e-mail between clients), but finer divisions exist.
