Neutralisation (leather Processing)
Neutralization may refer to: * Neutralization (chemistry), a chemical reaction where a base and an acid react to form a salt * Neutralisation (immunology), pathogen neutralization caused by antibodies * Neutralisation (sociology) * Neutralization (linguistics), the elimination of certain distinctive features of phonemes in certain environments * Insertion of a network in an amplifier to eliminate parasitic oscillation Parasitic oscillation is an undesirable electronic oscillation (cyclic variation in output voltage or current) in an electronic or digital device. It is often caused by feedback in an amplifying device. The problem occurs notably in RF, audio, and ... (electronics) * Neutralize the Threat (2011), title of a music album {{disambiguation ...

Neutralization (chemistry)
In chemistry, neutralization or neutralisation (see spelling differences) is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution. The pH of the neutralized solution depends on the acid strength of the reactants. Meaning of "neutralization" In the context of a chemical reaction the term neutralization is used for a reaction between an acid and a base or alkali. Historically, this reaction was represented as :acid + base (alkali) → salt + water For example: :HCl + NaOH → NaCl + H2O The statement is still valid as long as it is understood that in an aqueous solution the substances involved are subject to dissociation, which changes the ionization state of the substances. The arrow sign, →, is used because the reaction is complete, that is, neutralization is a quantitative reaction. A more general definition is base ...

Neutralisation (immunology)
A neutralizing antibody (NAb) is an antibody that defends a cell from a pathogen or infectious particle by neutralizing any effect it has biologically. Neutralization renders the particle no longer infectious or pathogenic. Neutralizing antibodies are part of the humoral response of the adaptive immune system against viruses, intracellular bacteria and microbial toxin. By binding specifically to surface structures (antigen) on an infectious particle, neutralizing antibodies prevent the particle from interacting with its host cells it might infect and destroy. Mechanism In order to enter cells, pathogens, such as circulating viral particles or extracellular bacteria, use molecules on their surfaces to interact with the cell surface receptors of their target cell which allows them to enter the cell and start their replication cycle. Neutralizing antibodies can inhibit infectivity by binding to the pathogen and blocking the molecules needed for cell entry. This can be due to the ...

Neutralisation (sociology)
Techniques of neutralization are a theoretical series of methods by which those who commit illegitimate acts temporarily neutralize certain values within themselves which would normally prohibit them from carrying out such acts, such as morality, obligation to abide by the law, and so on. In simpler terms, it is a psychological method for people to turn off "inner protests" when they do, or are about to do something they themselves perceive as wrong. The theory The idea of such techniques was first postulated by David Matza (born May 1, 1930) and Gresham Sykes (born 1922) during their work on Edwin Sutherland's Differential Association in the 1950s. While Matza and Sykes were at the time working on juvenile delinquency, they hypothocized that the same techniques could be found throughout society and published their ideas in ''Delinquency and Drift'' 1964. Matza and Sykes' hypothesis states that people are always aware of their moral obligation to abide by the law, and that they ha ...

Neutralization (linguistics)
In phonology and linguistics, a phoneme () is a unit of sound that can distinguish one word from another in a particular language. For example, in most dialects of English, with the notable exception of the West Midlands and the north-west of England, the sound patterns (''sin'') and (''sing'') are two separate words that are distinguished by the substitution of one phoneme, , for another phoneme, . Two words like this that differ in meaning through the contrast of a single phoneme form a ''minimal pair''. If, in another language, any two sequences differing only by pronunciation of the final sounds or are perceived as being the same in meaning, then these two sounds are interpreted as phonetic variants of a single phoneme in that language. Phonemes that are established by the use of minimal pairs, such as ''tap'' vs ''tab'' or ''pat'' vs ''bat'', are written between slashes: , . To show pronunciation, linguists use square brackets: (indicating an aspirated ''p'' in ''p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
