1. Agner Krarup Erlang. (The other senses werenamed after him).2. A concurrent functional language for largeindustrial real-time systems by Armstrong, Williams andVirding of Ellemtel, Sweden.Erlang is untyped. It has pattern matching syntax,recursion equations, explicit concurrency, asynchronousmessage passing and is relatively free from side-effects.It supports transparent cross-platform distribution. It hasprimitives for detecting run-time errors, real-time garbagecollection, modules, dynamic code replacement (changecode in a continuously running real-time system) and aforeign language interface.An unsupported free version is available (subject to anon-commercial licence). Commercial versions with support areavailable from Erlang Systems AB. An interpreter inSICStus Prolog and compilers in C and Erlang are availablefor several Unix platforms.Open Telecom Platform (OTP) is a set of libraries andtools.Commercial version (http://erlang.se/) - sales, support,training, consultants. Open-source version(http://erlang.org/) - downloads, user-contributedsoftware, mailing lists.Training and consulting (http://erlang-consulting.com/).E-mail: .[Erlang - "Concurrent Programming in Erlang", J. Armstrong, M.& Williams R. Virding, Prentice Hall, 1993. ISBN 13-285792-8.]3. 36 CCS per hour, or 1 call-second per second.Erlang is a unit without dimension, accepted internationallyfor measuring the traffic intensity. This unit is defined asthe aggregate of continuous occupation of a channel for onehour (3600 seconds). An intensity of one Erlang means thechannel is continuously occupied.

Platidiam
- An inorganic water-soluble platinum complex. After undergoing hydrolysis, it reacts DNA produce both intra interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity cisplatin correlates with cellular arrest in G2 phase cell cycle.
