unusual facts about reactive


Water-reactive

Water-reactive substances are classified as R2 under the UN classification system and as Hazard 4.3 by the United States Department of Transportation.


Advanced Silicon Etch

Advanced Silicon Etch (ASE) is a deep reactive ion etching (DRIE) technique to rapidly etch deep and high aspect ratio structures in silicon.

Allyl

Thus, CH2=CHCH2OH "has an allylic hydroxyl group." Allylic C-H bonds are about 15% weaker than the C-H bonds in ordinary Antigen

In order to keep the cytotoxic cells from killing cells just for presenting self-proteins, self-reactive T cells are deleted from the repertoire as a result of tolerance (also known as negative selection).

Autoimmunity

Clonal Anergy theory, proposed by Nossal, in which self-reactive T- or B-cells become inactivated in the normal individual and cannot amplify the immune response.

Ceruletide

Ceruletide also activates NADPH oxidase, a source of reactive oxygen species contributing to inflammation, as well as the Janus kinase/signal transducer, another inflammation inducer.

Drill string

When the vibrator tunes to the resonant frequency of the system, the reactive load impedance cancels out to zero by virtue of the inductance reactance (mass of the system) equalling the compliance or stiffness reactance (elasticity of the tubular).

Erythrulose

During UV irradiation free radicals, mainly superoxide/hydroperoxyl (ROS/RNS) are produced, that can react with the ketoamines (Amadori products) and other intermediates of the Maillard reaction.

Global optimization

HAZMAT Class 4 Flammable Solids

#Self-Reactive Materials: materials that are thermally unstable and that can undergo a strongly exothermic decomposition even without participation of oxygen (air).

HLA-DR5

HLA-DR5 reactive gene products are linked to serology of HLA-DRB3 (HLA-DR52).

Hydrothermal synthesis

George W. Morey at the Carnegie Institution and later, Percy W. Bridgman at Harvard University did much of the work to lay the foundations necessary to containment of reactive media in the temperature and pressure range where most of the hydrothermal work is conducted.

Hypochlorite

Part of the digestion mechanism involves an enzyme-mediated respiratory burst, which produces reactive oxygen-derived compounds, including superoxide (which is produced by NADPH oxidase).

Nitro blue tetrazolium chloride

When there is an NADPH oxidase defect, the phagocyte is unable to make reactive oxygen species or radicals required for bacterial killing.

PANDAS

To establish that a disorder is an autoimmune disorder, Witebsky criteria requires that there be (1) a self-reactive antibody, (2) that a particular target for the antibody is identified (autoantigen) (3) that the disorder can be caused in animals and (4) that transferring antibodies from one animal to another triggers the disorder (passive transfer).

Power quality compression algorithm

These parameters may include, for example, current and voltage RMS, phase relationship between waveforms of a multi-phase signal, power factor, frequency, THD, active power (KW), reactive power (Kvar), apparent power (KVA) and active energy (KWh), reactive energy (Kvarh) and apparent energy (KVAh) and many more.

Reactive flash volatilization

Reactive flash volatilization was demonstrated in 2006 in the journal Science by the high temperature (700–800 °C) conversion of soybean oil (triglycerides) and sugar (D-(+)-glucose) to synthesis gas (H2 + CO) and olefins (ethylene and propylene).

Reactive flash volatilization of solid particles composed of cellulose, starch, lignin, Quaking Aspen (Populus tremuloides) wood chips, and polyethylene was demonstrated in 2007 in the scientific journal Angewandte Chemie.

Reactive material

In the US military, reactive materials (RM) are a new class of materials currently being investigated by the Office of Naval Research and others as a means to increase the lethality of direct-hit or fragmentation warheads.

Reactive nitrogen species

Reactive nitrogen species (RNS) are a family of antimicrobial molecules derived from nitric oxide (·NO) and superoxide (O2·−) produced via the enzymatic activity of inducible nitric oxide synthase 2 (NOS2) and NADPH oxidase respectively.

Rebeca Modeling Language

Rebeca (acronym for Reactive Objects Language) is an actor-based modeling language with a formal foundation, designed in an effort to bridge the gap between formal verification approaches and real applications.

Resistojet rocket

A resistojet is a method of spacecraft propulsion (electric propulsion) that provides thrust by heating a (typically non-reactive) fluid.

Shigella dysenteriae

The most commonly observed signs associated with Shigella dysentery include colitis, malnutrition, rectal prolapse, tenesmus, reactive arthritis, and CNS problems.

Synchronous condenser

A PLC based controller with PF controller and regulator will allow the system to be set to meet a given power factor or can be set to produce a specified amount of reactive power.

Tetrathionate

Tetrathionate has also been found to serve as a terminal electron acceptor for Salmonella Typhimurium, whereas existing thiosulfate in the lumen of mammals is oxidized by reactive oxygen species released by the immune system (mainly NADPH oxidase produced superoxide) to form tetrathionate.

Typesafe Inc.

It provides an Open source platform for building Reactive applications for the JVM, consisting of the Play Framework, Akka middleware and Scala programming language—with additional supporting products and development tools such as the Scala IDE for Eclipse.

Vintilă Ciocâlteu

There, in collaboration with Otto Folin he co-developed the chemical reactive known as the Folin-Ciocalteu reagent (FCR).

Volt-ampere reactive

If the reactive power is too low, inductive loads such as transformers will be unable to maintain voltages necessary for the generation of electromagnetic fields, leading to a "Voltage collapses" that create blackouts .

The term var was proposed by the Romanian electrical engineer Constantin Budeanu and introduced in 1930 by the IEC in Stockholm, which has adopted it as the unit for reactive power.

Voltage compensation

Synchronous condensers—can be used to generate reactive power, when they are operated as a motor.
