Exploiting his androgynous appearance, the original cover of the UK version unveiled two months later would depict the singer wearing a dress: taking the garment with him, he wore it during interviews — to the approval of critics, including Rolling Stones John Mendelsohn who described him as " ravishing, almost disconcertingly reminiscent of Lauren Bacall "— and in the street, to mixed reaction including laughter and, in the case of one male pedestrian, producing a gun and telling Bowie to " kiss my ass ".

Boucher decided that instead of taking over David's tutelage, he would send David to his friend Joseph-Marie Vien ( 1716 – 1809 ), a painter who embraced the classical reaction to Rococo.

" The intended sense is that of a reaction that depends on taking in heat if it is to proceed.

The Maillard reaction will occur slowly at room temperature, taking from a few to several months to show visible darkening, but will speed-up dramatically with increasing temperatures.

The bond between the carbon and the bromine then undergoes heterolytic fission, with the bromine atom taking the donated electron and becoming the bromide ion ( Br < sup >−</ sup >), because a S < sub > N </ sub > 2 reaction occurs by backside attack.

The plan was to provoke a German reaction by laying mines in Norwegian waters, and once Germany showed signs of taking action UK troops would occupy Narvik, Trondheim and Bergen and launch a raid on Stavanger to destroy Sola airfield.

Interferons produce symptoms similar to influenza ; some people taking glatiramer experience a post-injection reaction manifested by flushing, chest tightness, heart palpitations, breathlessness, and anxiety, which usually lasts less than thirty minutes.

A thermite reaction taking place on a cast iron skillet

* Insulin allergy – This occurs when a person's body has an allergic or bad reaction to taking insulin made from non-human insulin ( e. g., from pork or beef or from bacteria ).

In contrast, historian Ben Rubin argues that because the American Revolution was a conflict that as often pitted neighbor against neighbor — Whigs ( advocates of Revolution ) against Tories ( loyalists to Britain )— as it pitted nascent Americans against the British, many people stayed neutral until goaded into taking a stand in reaction to military atrocities, such as those attributed to Tarleton, or individual atrocities, such as the death of Thomas Young's brother, or the burning of Thomas Sumter's house and the abuse of his wife, or the interrogation at knife point of William Bratton's wife, the beating of their young son, and the family's imprisonment in their own attic -- individual atrocities similar to those depicted in The Patriot.

A side reaction is an unwanted chemical reaction taking place that diminishes the yield of the desired product.

Machiavelli even encourages risk taking as a reaction to risk.

* drive the reaction to the right, by taking a reversible process and making it irreversible.

An inquest heard the suicide might have been a depressive reaction to the drug he was taking for severe acne.

The most notable reaction was the enactment of the Republikschutzgesetz ( Law for the Defense of the Republic ) taking effect on July 22nd, 1922.

The great statesman Pericles was closely associated with this new learning and a friend of Anaxagoras, however, and his political opponents struck at him by taking advantage of a conservative reaction against the philosophers ; it became a crime to investigate the things above the heavens or below the earth, subjects considered impious.

The number of reactions hinting at the actual process taking place is much smaller, for example the ene reaction or aldol reaction.

A parallel development taking shape in rural America was the American craft movement, which began as a reaction to the industrial revolution.

It is caused by a highly exothermic reaction taking place in a thin zone.

An example of a substitution reaction taking place by a so-called borderline mechanism as originally studied by Hughes and Ingold is the reaction of 1-phenylethyl chloride with sodium methoxide in methanol.

The reaction rate is found to the sum of S < sub > N </ sub > 1 and S < sub > N </ sub > 2 components with 61 % ( 3, 5 M, 70 ° C ) taking place by the latter.

Where this takes place, the catalytic velocity ( rate of reaction ) of the enzyme may be significantly faster than that of others.

The speed at which a reactions takes place is studied by reaction kinetics.

Catalysts are substances which change the pathway ( mechanism ) of a reaction which in turn increases the speed of a reaction by lowering the activation energy needed for the reaction to take place.

With a catalyst, a reaction which is kinetically inhibited by a high activation energy can take place in circumvention of this activation energy.

This reaction takes place almost exclusively in aromatic hydrocarbons, where it is called electrophilic aromatic substitution.

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.

It was found that the reaction of chymotrypsin with its substrate takes place in two stages, an initial “ burst ” phase at the beginning of the reaction and a steady-state phase following Michaelis-Menten kinetics.

A chain reaction is a sequence of reactions where a reactive product or by-product causes additional reactions to take place.

Oxidation and reduction describe the change of oxidation state that takes place in the atoms, ions or molecules involved in an electrochemical reaction.

Iron corrosion takes place on acid medium ; H < sup >+</ sup > ions come from reaction between carbon dioxide in the atmosphere and water, forming carbonic acid.

However, electrolysis requires an external source of electrical energy to induce a chemical reaction, and this process takes place in a compartment called an electrolytic cell.

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

The burning of gunpowder does not take place as a single reaction, however, and the byproducts are not easily predicted.

Although some form of reaction may take place, it is not necessary ; the method may work by attractive charges, for example, if the target particles are positively charged, use a negatively charged substrate.

When one reactant contains hydrogen atoms, a reaction can take place by exchanging protons in acid-base chemistry.

Volkov had insisted that all written communications about him take place by diplomatic bag rather than by telegraph, causing a delay in reaction that might plausibly have given the Soviets time to uncover his plans.

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 ".

The same reaction can take place between carbons 1 and 5 to form a molecule with a 6-membered ring, called glucopyranose.

It is an exothermic reaction which can release large amounts of energy both as electromagnetic radiation and as kinetic energy of the fragments ( heating the bulk material where fission takes place ).

If enough nuclear fuel is assembled in one place, or if the escaping neutrons are sufficiently contained, then these freshly emitted neutrons outnumber the neutrons that escape from the assembly, and a sustained nuclear chain reaction will take place.

Long before all possible fission has taken place, the buildup of long-lived neutron absorbing fission byproducts impedes the chain reaction.
