Argon was used as a blowing gas to exclude any effects of dissociation or chemical reaction.

This subject, who has been undergoing psychoanalytic psychotherapy for five years, did not give a positive Kohnstamm reaction under any of the four standardized conditions used in this experiment while sober.

They used a calorimeter to estimate the heat evolved per unit of carbon dioxide produced, eventually finding the same ratio for a flame and animals, indicating that animals produced energy by a type of combustion reaction.

On Monday, 8 May 1972, ground service equipment being used to empty the residual toxic reaction control system fuel in the command module tanks exploded in a Naval Air Station hangar.

This reaction can be used to determine the position of a double bond in an unknown alkene.

Only a proper, artist-grade acrylic gesso should be used to prime canvas in preparation for painting with acrylic ( however acrylic paint can be applied to raw canvas if so desired without any negative effect or chemical reaction as would be the case with oils ).

More recent IUPAC recommendations now suggest the newer term " hydronium " be used in favor of the older accepted term " oxonium " to illustrate reaction mechanisms such as those defined in the Brønsted – Lowry and solvent system definitions more clearly, with the Arrhenius definition serving as a simple general outline of acid – base character.

The enzyme itself is not used up in the process, and is free to catalyze the same reaction with a new set of substrates.

This restriction was based on the possibility that a small number of people might develop an allergic reaction to the Bt protein used in StarLink that is less rapidly digested than the version used in other Bt varieties.

A simple example can be seen in the combustion of hydrogen and oxygen, which is a commonly used reaction in rocket engines:

* Computational studies can be used to predict the possibility of so far entirely unknown molecules or to explore reaction mechanisms that are not readily studied by experimental means.

Such a surface can be used for reaction dynamics.

Any of these reactions may be used in LPCVD, but the silane reaction is also done in APCVD.

Normally, two or more different monomers are used in the reaction.

Another approach used is the reaction of di-functional monomers, with one amine and one carboxylic acid group on the same molecule:

A catalyst is not destroyed or changed during a reaction, so it can be used again.

The reaction takes place in the active site, a small part of the enzyme which is usually found in a cleft or pocket lined by amino acid residues, and the rest of the enzyme is used mainly for stabilization.

For example, the thermite reaction is used to generate light and heat in pyrotechnics and welding.

A less accessible but rather efficient method is introduction of a radioactive isotope into the reaction and monitoring how it changes over time and where it moves to ; this method is often used to analyze redistribution of substances in the human body.

It is uncertain where it was first discovered that a combination of hydrated non-hydraulic lime and a pozzolan produces a hydraulic mixture ( see also: Pozzolanic reaction ), but concrete made from such mixtures was first used by the Ancient Macedonians and three centuries later on a large scale by Roman engineers.

Special cryogenic chemical reactors are used to remove reaction heat and provide a low temperature environment.

* Polymerase chain reaction, a technique used in molecular biology to amplify ( make many copies of ) a piece of DNA by in vitro enzymatic replication using a DNA polymerase.

* In chemistry, it is often used to represent the addition of heat in a reaction.

In a full-size nuclear power plant, the heat of a nuclear reaction is used to run a heat engine.

It was possible to make estimates of the quantum yield by observing the extent of reduction of a uranyl oxalate actinometer solution illuminated for a known time in a typical reaction cell and making appropriate conversions based on the differences in the absorption spectra of uranyl oxalate and of chlorine, and considering the spectral distribution of the light source.

Other manufacturers, in reaction to the challenges from using this business model, choose to make more money on printers and less on the ink, promoting the latter through their advertising campaigns.

* Reactant concentrations, which usually make the reaction happen at a faster rate if raised through increased collisions per unit time.

* Activation energy, which is defined as the amount of energy required to make the reaction start and carry on spontaneously.

It is essential to make the reaction as efficient as possible, maximizing the yield and minimizing the amount of reagents, energy inputs and waste.

Methods for dealing with them tend to fall into one of two categories – either make the ceramic in the desired shape, by reaction in situ, or by " forming " powders into the desired shape, and then sintering to form a solid body.

Shelly Kagan examines the philosophical background of whether fear of death make sense ( not about the actual kind of emotional reaction ).

Von Trier has stated he was inspired to make a trilogy about the United States as a reaction to Americans at the Cannes film festival who said he had no right to make the Dancer in the Dark, which was often viewed as being critical of a country he has never been to ( and has no intention of ever visiting, due to his phobia of travel ); however, von Trier himself has stated in interviews he did not intend it to be a criticism of America, saying the film takes place in a " fictional America ".

)</ ref >< ref name = Lackner2012 > Such carbon neutral and negative fuels can be produced by the electrolysis of water to make hydrogen used in the Sabatier reaction to produce methane which may then be stored to be burned later in power plants as synthetic natural gas, transported by pipeline, truck, or tanker ship, or be used in gas to liquids processes such as the Fischer – Tropsch process to make traditional transportation or heating fuels .< ref name = Pearson2012 > ( Review.

An ATP synthase enzyme uses the chemiosmotic potential to make ATP during photophosphorylation, whereas NADPH is a product of the terminal redox reaction in the Z-scheme.

Because silver readily absorbs free neutrons, it is commonly used to make control rods to regulate the fission chain reaction in pressurized water nuclear reactors, generally in the form of an alloy containing 80 % silver, 15 % indium, and 5 % cadmium.

As a reaction to this, Stallman initiated the GNU project to make a new community.

Both of these make the reaction faster.

In Great Britain and Ireland, it was a reaction to Cisalpinism, the stance of moderate lay Catholics who sought to make patriotic concessions to the Protestant state to achieve Catholic emancipation.

The protons and electrons which make up the solar wind are deflected by this magnetosphere and the reaction accelerates the spacecraft.

For simplicity we neglect the neutrino ( neutrino accounting requires an exact calculation of all stages of the reaction, and the loss of neutrino energy make up only about one percent ), and annihilate the positrons with 2 electrons from hydrogen atoms remaining after the removal of these protons.

Moore was famous for " corpsing " — the programmes often went on live, and Cook would deliberately make him laugh in order to get an even bigger reaction from the studio audience.

It received mixed critical reaction, and was unable to make a profit.

This hygroscopic property coupled with an inherent exothermic ( heat-producing ) reaction when transitioning from a dehydrated to a hydrated form make natural zeolites useful in harvesting waste heat and solar heat energy.

" Because of strong video sales, the studio continued to make these films in spite of negative critical reaction ; 2001's Cinderella II: Dreams Come True received a rare zero-percent rating from the review-aggregating website Rotten Tomatoes.
