Question: The Grands Magasins Dufayel was a huge department store with inexpensive prices built in 1890 in the northern part of Paris, where it reached a very large new customer base in the working class. In a neighborhood with few public spaces, it provided a consumer version of the public square. It educated workers to approach shopping as an exciting social activity not just a routine exercise in obtaining necessities, just as the bourgeoisie did at the famous department stores in the central city. Like the bourgeois stores, it helped transform consumption from a business transaction into a direct relationship between consumer and sought-after goods. Its advertisements promised the opportunity to participate in the newest, most fashionable consumerism at reasonable cost. The latest technology was featured, such as cinemas and exhibits of inventions like X-ray machines (that could be used to fit shoes) and the gramophone.
Is there an answer to this question: Where was The Grands Magasins Dufayel built?

Answer: the northern part of Paris

Question: There are many important organozinc compounds. Organozinc chemistry is the science of organozinc compounds describing their physical properties, synthesis and reactions. Among important applications is the Frankland-Duppa Reaction in which an oxalate ester(ROCOCOOR) reacts with an alkyl halide R'X, zinc and hydrochloric acid to the -hydroxycarboxylic esters RR'COHCOOR, the Reformatskii reaction which converts -halo-esters and aldehydes to -hydroxy-esters, the SimmonsSmith reaction in which the carbenoid (iodomethyl)zinc iodide reacts with alkene(or alkyne) and converts them to cyclopropane, the Addition reaction of organozinc compounds to carbonyl compounds. The Barbier reaction (1899) is the zinc equivalent of the magnesium Grignard reaction and is better of the two. In presence of just about any water the formation of the organomagnesium halide will fail, whereas the Barbier reaction can even take place in water. On the downside organozincs are much less nucleophilic than Grignards, are expensive and difficult to handle. Commercially available diorganozinc compounds are dimethylzinc, diethylzinc and diphenylzinc. In one study the active organozinc compound is obtained from much cheaper organobromine precursors:
Is there an answer to this question: What are dimethylzinc, dietylzinc and diphenylzinc?

Answer: Commercially available diorganozinc compounds

Question: According to R. J. Rummel, genocide has 3 different meanings. The ordinary meaning is murder by government of people due to their national, ethnic, racial, or religious group membership. The legal meaning of genocide refers to the international treaty, the Convention on the Prevention and Punishment of the Crime of Genocide. This also includes non-killings that in the end eliminate the group, such as preventing births or forcibly transferring children out of the group to another group. A generalized meaning of genocide is similar to the ordinary meaning but also includes government killings of political opponents or otherwise intentional murder. It is to avoid confusion regarding what meaning is intended that Rummel created the term democide for the third meaning.
Is there an answer to this question: In which international treaty is the legal meaning of opponents contained?

Answer: unanswerable

Question: Although dissertations on clothing and its function appear from the 19th century as colonising countries dealt with new environments, concerted scientific research into psycho-social, physiological and other functions of clothing (e.g. protective, cartage) occurred in the first half of the 20th century, with publications such as J. C. Flugel's Psychology of Clothes in 1930, and Newburgh's seminal Physiology of Heat Regulation and The Science of Clothing in 1949. By 1968, the field of environmental physiology had advanced and expanded significantly, but the science of clothing in relation to environmental physiology had changed little. While considerable research has since occurred and the knowledge-base has grown significantly, the main concepts remain unchanged, and indeed Newburgh's book is still cited by contemporary authors, including those attempting to develop thermoregulatory models of clothing development.
Is there an answer to this question: Whose book entitled Physiology of Heat Regulation and The Science of Clothing was published in 1949?

Answer:
Newburgh's
