The Chemistry And Literature Of Beryllium - PDF
نویسندگان: خلاصه: All normal compounds of beryllium which are soluble in water are strongly acid in reaction to litmus, dissolve notable quantities of their own hydroxide which increases in amount with the concentration of the solution, set free carbon dioxide from carbonates and attack certain metals. In short, they act in many respects like the acids themselves would act from which they are derived. In spite of these facts they show less hydrolysis, and consequent smaller concentration of hydrogen ions, at least in the case of the chloride, nitrate and sulphate, (iveys, 1899; 10 and Brunner, 1900; 1) when treated by the well-known method of sugar inversion, than the corresponding salts of iron and aluminum. By the same method of determination, the hydrogen ions are thrown back into the undissociated condition when but a small fraction of the beryllium hydroxide has been dissolved which the normal salt is capable of holding in solution, (Parsons, 1904; 10). The reasons for these phenomena are not at present understood. The sulphate has been recently studied with a view to a solution of this problem, (1907; 10) and it has been shown that the addition of beryllium hydroxide to a solution of the sulphate, raises the freezing point and diminishes the conductivity; that no beryllium enters into the formation of a complex anion and that while the hydroxide can be partially removed by dialysis if dialyzed into pure water, there is little evidence of a colloid being present. It has been suggested that we may have here a new instance of solution, wherein the solid, when once dissolved, acts as a true solvent for its own oxide or hydroxide, and there are some analogies which point strongly to this view, (1907; n).
Cultures of Mass Tourism - Original PDF
نویسندگان: خلاصه: With more than 230 million international tourists a year, the Mediterranean region is the largest tourist destination in the world. Indeed, it is now less united by olive, grain and vine cultivation than the fortnightly pulse of the package tour, the circulation of resort types and the shared culture of sun-seeking tourism. This book argues that its economic importance is matched by its significance as cultural and aesthetic phenomena. Mass tourism has brought about new social and cultural formations that mix global, national and local influences. There has, as yet, been little analysis of these new cultural formations. This book offers a series of insights into some of the key sites of mass Mediterranean tourism, including the beach, the island, the tourist resort and the coastal hotel. It also focuses on the 'mass' element and reflects on the 'banal' experiences of the package tourist, as well as the serial and depthless spaces that are mushrooming along the coast and the enchantments, dissolutions and dreams that saturate them. Moving away from the notion of authentic places corrupted by mass tourism, it examines new forms and spaces created, co-produced by locals and tourists, seeing them as postmodern with reworked meanings such as the recoding the ancient with irony and kitsch. It also develops an approach which is sensitive to social practices and embodied performances such as photography, hotel activities and nightlife. Finally, the book looks at the complex materilities of mass tourism, as well as the many networks that make it possible. All in all, this volume provides an up-to the minute key reference on the cultures of mass tourism.
