Available in PDF, EPUB and Kindle. Book excerpt: If we possessed a true, well established and undoubted theory concerning the function of the nerves in the human body, the principles of smell would be much easier to understand. So far, we do not know for certain whether the action of nerves takes place by means of a subtle fluid, which is instantaneously conveyed from the beginning of the nerves to their ends, or whether, as some think, some sort of vibratory movements is produced in them, or whether the stimulation should be considered as the only sufficient cause, to say nothing of the new opinion concerning the electrical force. Linnaeus Although much has been learned since the time of Linnaeus, it is still true that we do not yet possess "a true, well established and undoubted" theory of olfaction. The literature of the subject, however, has long been rather voluminous - the frequent assertions to the contrary are simply untrue - and is now growing rapidly. Moreover, quite a number of symposia on olfaction (or olfaction and taste) have been held during recent years. For example, in the U. S. A.

Book excerpt: The Toxic Museum examines the use of pesticides in German museum collections at the end of the 19th and early 20th centuries. It reconstructs the research of substances against harmful insects in museum collections within the historical context of the formation of nation-states, colonialism, a strengthening chemical industry, the First World War, and the resulting broad-based hygiene movement through the lens of the Ethnologisches Museum (Ethnological Museum) in Berlin. Because of their persistence, the consequences of the use of pesticides in museum collections are now unmistakable and well documented in many places. Numerous objects are highly contaminated and are only accessible under difficult conditions regarding occupational health and safety. This creates obstacles for conservation and scientific processing, as well as for mediation in the context of exhibitions and external loans. The most precarious and difficult situations arise when contaminated museum objects are repatriated to their countries of origin. This monograph examines contemporary challenges in the 21st century museum landscape and contextualises the history of pesticide use at the turn of the 20th century. The Toxic Museum will be of great interest to students and scholars working in conservation, museology, monument preservation, art and cultural studies, ethnology, history, and economics.

This book was released on 2012-12-06 with total page 774 pages. Available in PDF, EPUB and Kindle. Book excerpt: If, following the solvent extraction of a hydrocarbon from a plant, it is not known whether it is one or the other, a method of distinguishing the two is described by HENDRICKS, WILDMAN and JONES (1946). The technique involves the infra-red absorption spectra of the two isomers. At about 12 mp. the relative absorption coefficient of rubber is 42% greater than for gutta. ScHLESINGER and LEPER (1951) describe two procedures for separation of the rubber and gutta hydrocarbons from large quantities of crude chicle. In one, the chicle is extracted with benzene which dissolves both isomers. An excess absolute ethyl acetate is added and the mixture stored at 5° C overnight. The gutta precipitates out and the rubber remains in solution. The other method is as follows: (1) Ten grams of chicle are extracted with acetone for 24 hours in a Soxhlet extraction apparatus. (2) The insoluble material in the thimble is allowed to .. it dry, then immersed in 150 ml. of cold Skellysolve B in a refrigerator at 10° C and· allowed to stand for 48 hours with occasional agitation. (3) The thimble is then removed from the solvent and the enclosed residue washed several times with fresh, cold Skellysolve B. (4) An excess of acetone and a few drops of a concentrated aqueous solution of sodium iodide are added to the combined Skellysolve B extract and washings and allowed to stand overnight in a refrigerator.
