A stock transfer agent, transfer agent, share registry or transfer agency is an entity, usually a third-party firm unrelated to security transactions, that manages the change in ownership of company stock or investment fund shares, maintains a register of ownership and acts as paying agent for the payment of dividends and other distributions to investors.
Within the Internet email system, a message transfer agent ( MTA ), [1] mail transfer agent, [2] or mail relay is software that transfers electronic mail messages from one computer to another using the Simple Mail Transfer Protocol. [3] In some contexts, the alternative names mail server, mail exchanger, or MX host are used to describe an MTA.
Chain transfer. In polymer chemistry, chain transfer is a polymerization reaction by which the activity of a growing polymer chain is transferred to another molecule: [1] [2] where • is the active center, P is the initial polymer chain, X is the end group, and R is the substituent to which the active center is transferred.
Central securities depository. A central securities depository ( CSD) is a specialized financial market infrastructure organization holding securities like shares, either in certificated or uncertificated ( dematerialized) form, allowing ownership to be easily transferred through a book entry rather than by a transfer of physical certificates.
Reversible addition−fragmentation chain-transfer or RAFT polymerization is one of several kinds of reversible-deactivation radical polymerization. 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 ...
Transfer function. In engineering, a transfer function (also known as system function [1] or network function) of a system, sub-system, or component is a mathematical function that models the system's output for each possible input. [2] [3] [4] It is widely used in electronic engineering tools like circuit simulators and control systems.
Email agent (infrastructure) 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 ...
In chemistry, transfer hydrogenation is a chemical reaction involving the addition of hydrogen to a compound from a source other than molecular H2. It is applied in laboratory and industrial organic synthesis to saturate organic compounds and reduce ketones to alcohols, and imines to amines. It avoids the need for high-pressure molecular H2 ...
