* Event-driven process chain, a concept in Business Process Modeling

Event-driven Process Chain is a business process modelling technique, mainly used for analysing processes for the purpose of an ERP implementation.

An Event-driven Process Chain ( EPC ) is a type of flowchart used for business process modelling.

# Event-driven process automation-where background processes cannot be simply run at a defined time, either because the nature of the business demands that workload is based on the occurrence of external events ( such as the arrival of an order from a customer or a stock update from a store branch ) or because there is no / insufficient batch window.

ARIS uses a modeling language known as Event-driven Process Chains ( EPC ), which is an important aspect of the ARIS-model.

In the new process impurities present in the solvent ( benzene ), the monomer, and in the reaction system which would cause deactivation of propagation centers, are rendered inactive prior to polymerization by gradual addition of initiator, a mixture of butyl-lithium and telomeric styryl-lithium, at a temperature low enough to suppress chain growth.

The process of making proteins is called translation and involves the step-by-step addition of amino acids to a growing protein chain by a ribozyme that is called a ribosome.

Antibody genes also re-organize in a process called class switching that changes the base of the heavy chain to another, creating a different isotype of the antibody that retains the antigen specific variable region.

In this process, the superoxide anion is produced as a by-product of several steps in the electron transport chain.

At high temperatures, organobromine compounds are easily converted to free bromine atoms, a process which acts to terminate free radical chemical chain reactions.

This process usually takes the form of a chain reaction, for example in the reaction of alkanes with halogens.

In the process of oxidative phosphorylation, which is the principal energy-generating process undertaken by organisms, which need oxygen to survive, other membrane-bound and-soluble complexes and cofactors are involved in the chain of redox reactions, with the additional net effect that protons ( H < sup >+</ sup >) are transported across the mitochondrial inner membrane.

Crocheted fabric is begun by placing a slip-knot loop on the hook ( though other methods, such as a magic ring or simple folding over of the yarn may be used ), pulling another loop through the first loop, and repeating this process to create a chain of a suitable length.

The citric acid cycle oxidizes the acetyl-CoA to carbon dioxide, and, in the process, produces reduced cofactors ( three molecules of NADH and one molecule of FADH < sub > 2 </ sub >) that are a source of electrons for the electron transport chain, and a molecule of GTP ( that is readily converted to an ATP ).

Some fraction of elements beyond helium were created in the Big Bang, as the protons and neutrons collided with each other ( lithium, beryllium, and perhaps some boron ), but all of the " heavier elements " ( heavier than carbon, element number 6 ) that we see today, were created inside of stars during a series of fusion stages, such as the proton-proton chain, the CNO cycle and the triple-alpha process.

During part of this process, the assembly is supercritical, but not yet in an optimal state for a chain reaction.

Modern scientific instruments can extensively process " observations " before they are presented to the human senses, and particularly with computerized instruments, there is sometimes a question as to where in the data processing chain " observing " ends and " drawing conclusions " begins.

The energy released by electrons flowing through this electron transport chain is used to transport protons across the inner mitochondrial membrane, in a process called chemiosmosis.

The flow of electrons through the electron transport chain, from electron donors such as NADH to electron acceptors such as oxygen, is an exergonic process – it releases energy, whereas the synthesis of ATP is an endergonic process, which requires an input of energy.

Both the electron transport chain and the ATP synthase are embedded in a membrane, and energy is transferred from electron transport chain to the ATP synthase by movements of protons across this membrane, in a process called chemiosmosis.

Polymerization is the process of combining many small molecules known as monomers into a covalently bonded chain or network.

In animal cells, the very long fatty acids are converted to medium chain fatty acids, which are subsequently shuttled to mitochondria where they are eventually broken down to carbon dioxide and water. In yeast and plant cells, this process is exclusive for the peroxisomes.

Likening human life to the life of other animals, he saw the reproductive cycle as indeed a cyclical process that continues pointlessly and indefinitely, unless the chain is broken by too limited resources to make continued life possible, in which case it is terminated by extinction.

The huge luminosity of quasars results from the accretion discs of central supermassive black holes, which can convert on the order of 10 % of the mass of an object into energy as compared to 0. 7 % for the p-p chain nuclear fusion process that dominates the energy production in sun-like stars.

* In supply chain management, standardization refers to approaches for increasing commonality of either part, process, product or procurement.

Information shared between supply chain partners can only be fully leveraged through process integration.

Supply chain business process integration involves collaborative work between buyers and suppliers, joint product development, common systems and shared information.

Unique pressure classes for piping can also be developed for a process plant or power generating station ; these may be specific to the corporation, engineering procurement and construction ( EPC ) contractor, or the process plant owner.

Businesses use EPC diagrams to lay out business process work flows, originally in conjunction with SAP R / 3 modeling, but now more widely.

EPC diagrams use symbols of several kinds to show the control flow structure ( sequence of decisions, functions, events, and other elements ) of a business process.

EPC is the center of the House of ARIS and connects all other views, as well as describes the dynamics of the business process.

The international standards organization EPCglobal under GS1 has ratified the EPCglobal Network standards ( especially the EPC Information Services EPCIS standard ) which codify the syntax and semantics for supply chain events and the secure method for selectively sharing supply chain events with trading partners.

The federation was established in 1999 ; the network they have developed is at the heart of a proposal sponsored by EPCglobal and supported by GS1, GS1 US, Wal-Mart, Hewlett-Packard, and others to use RFID and the Electronic Product Code ( EPC ) in the identification of items in the supply chain for companies.
