Desensitization (telecommunications)
In telecommunications, desensitization (also known as receiver blocking) is a form of electromagnetic interference where a radio receiver is unable to receive a weak radio signal that it might otherwise be able to receive when there is no interference. This is caused by a nearby transmitter with a strong signal on a close frequency, which overloads the receiver and makes it unable to fully receive the desired signal. Typical receiver operation is such that the Minimum Detectable Signal (MDS) level is determined by the thermal noise of its electronic components. When a signal is received, additional spurious signals are produced within the receiver because it is not truly a linear device. When these spurious signals have a power level that is less than the thermal noise power level, then the receiver is operating normally. When these spurious signals have a power level that is higher than the thermal noise floor, then the receiver is desensitized. This is because the MDS has risen d ...

Desensitization (medicine)
In medicine, desensitization is a method to reduce or eliminate an organism's negative reaction to a substance or stimulus. In pharmacology, ''drug desensitization'' refers to two related concepts. First, desensitization may be equivalent to drug tolerance and refers to subjects' reactions (positive or negative) to a drug reducing following its repeated use. This is a macroscopic, organism-level effect and differs from the second meaning of desensitization, which refers to a biochemical effect where individual receptor (biochemistry), receptors become less responsive after repeated application of an agonist. This may be mediated by phosphorylation, for instance by beta adrenoceptor kinase at the beta adrenoceptor. Application to allergies For example, if a person with diabetes mellitus has a bad allergy, allergic reaction to taking a full Dose (biochemistry), dose of beef insulin, the person is given a very small amount of the insulin at first, so small that the person has no adve ...

Desensitization (psychology)
Desensitization (from Latin ''"de-"'' meaning "removal" and ''"sensus"'' meaning "feeling" or "perception") is a psychology term related to a treatment or process that diminishes emotional responsiveness to a negative or aversive stimulus after repeated exposure. This process typically occurs when an emotional response is repeatedly triggered, but the action tendency associated with the emotion proves irrelevant or unnecessary. Psychologist Mary Cover Jones pioneered early desensitization techniques to help individuals "unlearn" (disassociate from) phobias and anxieties. Her work laid the foundation for later structured approaches to desensitization therapy, aimed at gradually reducing emotional reactions to previously distressing situations. In 1958, Joseph Wolpe developed a ranked list of anxiety-evoking stimuli ordered by intensity to help individuals gradually adapt to their fears. Wolpe's "reciprocal inhibition" desensitization process is based on established psycholog ...

Phlegmatized
A phlegmatized explosive is an explosive that has had an agent (a phlegmatizer) added to stabilize or desensitize it. Phlegmatizing usually improves the handling properties of an explosive (e.g. when munitions are filled in factories.) Trinitrotoluene can itself be used to phlegmatize more sensitive explosives such as RDX (to form Cyclotol), HMX (to form Octol), or PETN (to form Pentolite). Other typical phlegmatizing agents include paraffin wax (5% used in OKFOL and Composition H6), paper, or even water Water is an inorganic compound with the chemical formula . It is a transparent, tasteless, odorless, and Color of water, nearly colorless chemical substance. It is the main constituent of Earth's hydrosphere and the fluids of all known liv ... (used in water gel explosives). Such agents are nearly always flammable themselves (therefore adding fuel to the blast) or will at least boil off easily. Typically, a small amount of phlegmatizing agent is used, such ...

Allergen Immunotherapy
Allergen immunotherapy, also known as desensitization or hypo-sensitization, is a medical treatment for environmental allergies (such as insect bites) and asthma. Immunotherapy involves exposing people to larger and larger amounts of allergens in an attempt to change the immune system's response. Meta-analyses have found that injections of allergens under the skin are effective in the treatment of allergic rhinitis in children and in asthma. The benefits may last for years after treatment is stopped. It is generally safe and effective for allergic rhinitis, allergic conjunctivitis, allergic forms of asthma, and stinging insects. The evidence also supports the use of sublingual immunotherapy against rhinitis and asthma, but it is less strong. In this form the allergen is given under the tongue and people often prefer it to injections. Immunotherapy is not recommended as a stand-alone treatment for asthma. Side effects during sublingual immunotherapy treatment are usually lo ...
