Hypochlorite
In chemistry, hypochlorite is an anion with the chemical formula ClO−. It combines with a number of cations to form hypochlorite salts. Common examples include sodium hypochlorite (household bleach) and calcium hypochlorite (a component of bleaching powder, swimming pool "chlorine"). The Cl-O distance in ClO− is 1.69 Å. The name can also refer to esters of hypochlorous acid, namely organic compounds with a ClO– group covalently bound to the rest of the molecule. The principal example is tert-butyl hypochlorite, which is a useful chlorinating agent. Most hypochlorite salts are handled as aqueous solutions. Their primary applications are as bleaching, disinfection, and water treatment agents. They are also used in chemistry for chlorination and oxidation reactions. Reactions Acid reaction Acidification of hypochlorites generates hypochlorous acid, which exists in an equilibrium with chlorine. A high pH drives the reaction to the left: :2 + + + Stability ...

Object Constraint Language
The Object Constraint Language (OCL) is a declarative language describing rules applying to Unified Modeling Language (UML) models developed at IBM and is now part of the UML standard. Initially, OCL was merely a formal specification language extension for UML. OCL may now be used with any Meta-Object Facility (MOF) Object Management Group (OMG) meta-model, including UML. The Object Constraint Language is a precise text language that provides constraint and object query expressions on any MOF model or meta-model that cannot otherwise be expressed by diagrammatic notation. OCL is a key component of the new OMG standard recommendation for transforming models, the Queries/Views/Transformations ( QVT) specification. Description OCL is a descendant of Syntropy, a second-generation object-oriented analysis and design method. The OCL 1.4 definition specified a constraint language. In OCL 2.0, the definition has been extended to include general object query language definitions. O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM Open Class
IBM Open Class (IOC) is an IBM C++ product originally developed by Kevin Leong and originally known under several names in the C++ industry, including ICL (IBM Class Library), UICL (User Interface Class Library), and OCL (Open Class Library). IOC was an extensive set of C++ classes used to build CLI and GUI applications which could then be easily cross-compiled to OS/2, Microsoft Windows, and AIX. IOC also formed the basis for IBM's VisualAge for C++ graphical application builder. The non-GUI portions of IOC were available for z/OS and OS/400. History of IOC The IOC was included as part of IBM's C++ compiler environment. Applications developed with IOC could be distributed with a royalty-free runtime, or could be statically linked against the IOC libraries. Initially only available for OS/2, the IOC was eventually made available for Windows, AIX, z/OS, and OS/400. Support for the OS/2 and Windows VisualAge for C++ compiler—as well as the accompanying IOC—was officially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operational Control Language
{{Unreferenced, date=October 2017 Operational Control Language (OCL) is the control language of the IBM System/32, System/34 and System/36 minicomputer family. It is supported on IBM i's System/36 Environment for backwards compatibility purposes. It is similar to the older control languages JCL (System/370) and System/3, and unrelated to the later Control Language (System/38 and IBM AS/400), and REXX Rexx (Restructured Extended Executor) is a programming language that can be interpreted or compiled. It was developed at IBM by Mike Cowlishaw. It is a structured, high-level programming language designed for ease of learning and reading. ... (AS/400). Overview On the IBM S/32, S/34 and S/36, OCL statements are used to directly load user or system programs into memory, assign system resources to them, and transfer system control to them in a process called execution. The fact that a program is stored on a computer's disk drive does not in itself cause the computer to proces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overseas Containers Limited
Overseas Containers Limited (OCL) was a container shipping company formed by a consortium of British shipping companies in 1965. It was taken over by P&O in 1986. It is not to be confused with Orient Overseas Container Line (OOCL). History In the early days of containerisation considerable investment was still required in the necessary infrastructure to transport and handle shipping containers, and many shipping companies formed consortia to ease the financial burden. OCL was formed in 1965 by four British companies: British and Commonwealth Shipping, Furness Withy, P&O and the Ocean Steamship Company. Between 1969 and 1970 OCL took delivery of its first ships, a fleet of six vessels of and capacity for the UK/Europe to Australia route. Initially operating from a set of offices in Bevis Marks, London, OCL later moved to custom built offices on Braham Street, a few hundred yards away on a traffic island at the end of Commercial Road. The service was inaugurated on 6 March 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
