(Tıp) Katalizör: "Activation" sağlayan madde: Aktivatör: a) "Flotation" metodunda minerallerin ayrılmasını kolaylaştıran madde (mesela kurşun karbonat filizleri için sodyum sülfit: "Blende" Zn için bakır sülfat aktivatör rol oynar). b) "Zymogen", "proenzyms" ve "proferment"leri gerçek veya aktif mayalar haline geçirmek için kullanılan kimyasal maddeler (asitler, bazlar ve tuzlar gibi). c) Organizmada bir fonksiyonu kamçılamak için kullanılan madde (mesela kolestrin ve balık yağı paratiroid bezini, "enterokinase" pankreas özsuyunda bulunan "trypsinogen"i kamçılar)
Activators are additives to the compost pile which contain a nitrogen source or sugars Their purpose is to increase microbial activity Generally, adequate nitrogen organic waste is the only activator needed If you have insufficient nitrogen, a substance like cottonseed meal may be added to encourage decomposition
A form designed to enable NRC clients to transmit information about a debt to NRC to begin the collection process By using the activator to transmit debt information, the client does not need to submit (or copy) original debt information to begin the collection process With paper-based NRC systems, the activator resembles a check in a one-write accounting system With the electronic Tandem Online program, the activator is completed online and immediately transmitted to NRC for collection
A removable growth guidance orthodontic appliance,originally developed by Pierre Robin,Viggo Andresen and Karl Haupl,with later modifications by Schwarz,Bimler, Balters,Franker, Fleischer-Peters,etc Also called a functional appliance
A substance that is used in a dye bath to fix the dye It raises the alkalinity of the dye bath to enable the necessary chemical reaction An example is the use of Soda Ash with fiber reactive dyes
(1) a chemical used to accelerate a reaction or increase chemical activity in another material; (2) in photography, a high pH solution which allows diffusion of the developer into the film emulsion for development of the image
A substance added in small quantity to promote the activity of a majority ingredient Often, trace cupric materials are added to zinc sulfide reflective paints to enhance brilliance
(biology) any agency bringing about activation; a molecule that increases the activity of an enzyme or a protein that increases the production of a gene product in DNA transcription
Used in composting to stimulate biological activity Because they are usually high in nitrogen, activators feed microorganism; they might also contain other decay organisms which become introduced to the compost via the activator
