Distributed Network Protocol 3 (DNP3) is a set of communications protocols used between components in process automation systems. Its main use is in utilities such as electric and water companies. Usage in other industries is not common. It was developed for communications between various types of data acquisition and control equipment.
Distributed Network Protocol , a protocol used in SCADA systems for communication with remote terminal units and intelligent electronic devices "Do not populate" or "do not place", a term used in printed circuit board design to denote the omitting of a component; Dynamic nuclear polarization, a technique used in NMR spectroscopy
It is commonly used as the hindered base in amide coupling reactions between a carboxylic acid (typically activated, for example, as an acid chloride, as illustrated below) and a nucleophilic amine. [5] As DIPEA is hindered and poorly nucleophilic, it does not compete with the nucleophilic amine in the coupling reaction.
The following diagram shows how the hindered base, lithium diisopropylamide, is used to deprotonate an ester to give the enolate in the Claisen ester condensation, instead of undergoing a nucleophilic substitution. This reaction (deprotonation with LDA) is commonly used to generate enolates.
The reaction mechanism of the Mitsunobu reaction is fairly complex. The identity of intermediates and the roles they play has been the subject of debate. Initially, the triphenyl phosphine (2) makes a nucleophilic attack upon diethyl azodicarboxylate (1) producing a betaine intermediate 3, which deprotonates the carboxylic acid (4) to form the ion pair 5.
Seasonal flu activity is elevated across most of the country, according to the latest reports from the Centers for Disease Control and Prevention, and experts say this is expected to continue for ...
The specific content regarding the security research related to DNP3 and opendnp3 was covered in well-respected industry blogs like Digitalbond in addition to the mainstream media like the New York Times and Wired Magazine. This is clearly of importance, but I welcome anyone else to make the language more neutral if they see anything out of sorts.
