  2. Electrocoagulation - Wikipedia

    en.wikipedia.org/wiki/Electrocoagulation

    Electrocoagulation (EC) is a technique used for wastewater treatment, wash water treatment, industrially processed water, and medical treatment. Electrocoagulation has become a rapidly growing area of wastewater treatment due to its ability to remove contaminants that are generally more difficult to remove by filtration or chemical treatment systems, such as emulsified oil, total petroleum ...

  3. Electrosurgery - Wikipedia

    en.wikipedia.org/wiki/Electrosurgery

    Electrosurgery. A surgeon using a monopolar RF electrosurgical instrument to coagulate (and desiccate) tissue in the excision of a lipoma. MeSH. D004598. [ edit on Wikidata] Electrosurgery is the application of a high-frequency (radio frequency) alternating polarity, electrical current to biological tissue as a means to cut, coagulate ...

  4. Decentralized wastewater system - Wikipedia

    en.wikipedia.org/.../Decentralized_wastewater_system

    A case study of a decentralized wastewater system at on-site level with treated effluent reuse was performed at the Botswana Technology Centre in Gaborone, Botswana. [22] It is an example of a decentralized wastewater system, which serves one institutional building, located in an area served by municipal sewerage.

  5. Variable electro-precipitator - Wikipedia

    en.wikipedia.org/wiki/Variable_electro-precipitator

    A variable electro-precipitator (VEP) is a waste water remediation unit using electrocoagulation. The differences between a standard electrocoagulation (EC) unit and a variable Electro-precipitation unit are in the enhanced flow path and the unit electrode connections. The variable electro-precipitator's flow path has been designed to maximize ...

  6. Anti-access/area denial - Wikipedia

    en.wikipedia.org/wiki/Anti-access/area_denial

    A2/AD strategy is a significant concern of US policy, viewing it as a weapon of weaker forces that could be used against the US military. [2] The US military considers that enemy adoption of anti-access/area denial strategies "may well be the most difficult operational challenge U.S. forces will face over the coming decades."

  7. History of electrochemistry - Wikipedia

    en.wikipedia.org/wiki/History_of_electrochemistry

    History of electrochemistry. Electrochemistry, a branch of chemistry, went through several changes during its evolution from early principles related to magnets in the early 16th and 17th centuries, to complex theories involving conductivity, electric charge and mathematical methods. The term electrochemistry was used to describe electrical ...

  8. List of unsolved problems in physics - Wikipedia

    en.wikipedia.org/wiki/List_of_unsolved_problems...

    The following is a list of notable unsolved problems grouped into broad areas of physics. [1]Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result.

  9. Arrow's impossibility theorem - Wikipedia

    en.wikipedia.org/wiki/Arrow's_impossibility_theorem

    Because of this example, some authors credit Condorcet with having given an intuitive argument that presents the core of Arrow's theorem. [36] However, Arrow's theorem is substantially more general and even applies to many "unfair" systems for making decisions, which give some voters more influence than others or favor some candidates over others.
