Differential thermal analysis showed a very small endothermic reaction at 340-degrees-C and a large endothermic reaction at 470-degrees-C.

The small reaction occurring at 337-degrees-C is probably caused by decomposition of occluded nitrates, and perhaps by a small amount of some hydrous material other than Af.

The rate of the gas phase exchange reaction appears to be proportional to the first power of the absorbed light intensity indicating that the radical intermediates are removed at the walls or by reaction with an impurity rather than by bimolecular radical combination reactions.

The reaction rates observed at 200-degrees ranged from Af of the chlorine exchanged per hour to 0.7 exchanged per hour.

No detectable reaction was found at room temperature for reaction mixtures allowed to stand up to 5 hours.

In the new process impurities present in the solvent ( benzene ), the monomer, and in the reaction system which would cause deactivation of propagation centers, are rendered inactive prior to polymerization by gradual addition of initiator, a mixture of butyl-lithium and telomeric styryl-lithium, at a temperature low enough to suppress chain growth.

Upon completion of the purging step, additional initiator appropriate for the molecular weight of the sample desired is added, and the system is then warmed to the polymerization temperature, at which the reaction is allowed to go to completion.

Basically, this means that simpler processing equipment ( the mixture has good flowing characteristics ) and less external heat ( the foaming reaction is exothermic and develops internal heat ) are required in one-shot foaming, although, at the same time, the problems of controlling the conditions of one-shot foaming are critical ones.

While most everyone has an experience with anxiety at some point in their lives, as it is a common reaction to real or perceived threats of all kinds, most do not develop long-term problems with anxiety.

He showed that, although matter can change its state in a chemical reaction, the total mass of matter is the same at the end as at the beginning of every chemical change.

The reaction is carried out under pressure at a temperature of 200 ° C in the presence of a metallic catalyst.

The reaction works because the high electron density at the double bond causes a temporary shift of electrons in the Br-Br bond causing a temporary induced dipole.

Polymerization of alkenes is a reaction that yields polymers of high industrial value at great economy, such as the plastics polyethylene and polypropylene.

" However, when informed of this, author Saga's reaction was to feel honored and not abused at Dylan's use of lines from his work.

Reactions with chalcogens are highly exothermic ( release energy ); the reaction with oxygen or air occurs at room temperature, and therefore barium is stored under oil or inert gas atmosphere.

The first convincing synthesis was in 1981 by a German research team led by Peter Armbruster and Gottfried Münzenberg at the Gesellschaft für Schwerionenforschung ( Institute for Heavy Ion Research, GSI ) in Darmstadt using the Dubna reaction.

The synthesis of bohrium was first attempted in 1976 by scientists at the Joint Institute for Nuclear Research at Dubna using this cold fusion reaction.

The team at Dubna studied this reaction in 1976 in order to assist in their assignments of the SF activities from their experiments with a < sup > 54 </ sup > Cr beam.

The revelation that one senior Catholic bishop, Eamon Casey, fathered a child by a divorcée caused a major reaction, as did the discovery of child abuse by a large number of clerics, notably the infamous paedophile Father Brendan Smyth ( the incompetent handling of a request for the extradition of Smyth brought down an Irish government in 1994 ).

This presentation might reflect on Kádár's reaction to Rajk's execution and his revelation that he might become the next victim of government repression.

Several alternate-universe episodes address the public reaction to the revelation of the Stargate Program.

His reaction is eventually explained with the revelation that his brother David, who was recently diagnosed with terminal cancer, committed suicide rather than live what time he had left, " He could have had years.

Oddly, Spike treats this revelation with total equanimity ; Dawn's reaction, of course, is far more vivid.

Hanoverian agents assisted in promoting circulation, said to have reached 40,000, and if one may judge by the reaction of Swift and other government writers, the work must have had considerable impact.

Even before the century was out the tide of reaction had set in.

Andrei remembered that his own reaction had been one of indifference.

When typical reaction cells to which 0.3 of an atmosphere of oxygen had been added were illuminated, chlorine and phosgene were produced.

There were 49% ( 20 subjects ) who did not give a positive reaction even after they were informed of the normalcy of such a reaction and had been given a demonstration.

They felt that they too could counteract the upward arm movement by a voluntary effort after they had once experienced the reaction.

Initially the White House reaction was that the bitter exchanges with Moscow over Cuba and the conflict in Laos had dampened prospects for a meeting.

from reaction times ( the " personal equation ") and had developed

What they and many others of that generation in the Nordic countries had in common was that they started off from a classical education and were first designing in the so-called Nordic Classicism style – a style that had been a reaction to the previous dominant style of National Romanticism – before moving, in the late 1920s, towards Modernism.

The Soviet scientists had suggested this name be given to element 105 ( which was finally called dubnium ) and the German team wished to recognise both Bohr and the fact that the Dubna team had been the first to propose the cold fusion reaction.

Retrieved on 2008-02-29 </ ref > The team found that this reaction had a higher 1n cross section than the corresponding reaction with a < sup > 209 </ sup > Bi target, contrary to expectations.

This could have been meant as a reaction against death metal bands, who at that time had begun to use brightly-colored album artwork.

However, the law of mass action is valid only for concerted one-step reactions that proceed through a single transition state and is not valid in general because rate equations do not, in general, follow the stoichiometry of the reaction as Guldberg and Waage had proposed ( see, for example, nucleophilic aliphatic substitution by S < sub > N </ sub > 1 or reaction of hydrogen and bromine to form hydrogen bromide ).

" The four National Gendarmerie legions each had a general staff, detached companies that were deployed in and around the major towns and population centers in their respective prefectures, and a small number of mobile squads for rapid reaction and general support.

In reaction to this report, the UK government banned anyone who had received a blood transfusion since January 1980 from donating blood.

Public reaction was mixed ; some accepted the images as genuine, but others believed they had been faked.

Szilárd knew of chemical chain reactions, and he had been reading about an energy-producing nuclear reaction involving high-energy protons bombarding lithium, demonstrated by John Cockcroft and Ernest Walton, in 1932.

In part, it was conceived in reaction to the French Encyclopédie of Denis Diderot and Jean le Rond d ' Alembert ( published 1751 – 1772 ), which had been inspired by Chambers's Cyclopaedia ( first edition 1728 ).

In the late 19th century, Josiah Willard Gibbs had formulated a theory to predict whether a chemical reaction is spontaneous based on the free energy

" Indeed, ELIZA's code had not been designed to evoke this reaction in the first place.
