Taschenbuch. Zustand: Neu. Neuware -The aims of this study are to modify heat cured acrylic resin denture base material into a flexible heat cured acrylic resin material by using additives {Flavoring agents and Plasticizer and to study some of it''s physical and mechanical properties.One hundred sixty of heat cured samples and standard flexite have been prepared for studying some physical properties and tensile strength. The samples have been tested to measure (Tensile strength, Water sorption, Solubility, Color change, Dimensional accuracy). The results of this study have shown that the tensile strength of heat cured acrylic resin with additives was significantly lower than the standard heat cured acrylic resin while standard flexite group was significantly higher than standard heat cured acrylic resin. For dimensional accuracy, water sorption and solubility test, the group has shown significantly lower dimensional change,water sorption and solubility than other groups with additives but still higher than control group and flexite (valplast) one during seven days periods.For color change test there has been a change in color between groups that even cannot be considered.Books on Demand GmbH, Überseering 33, 22297 Hamburg 128 pp. Englisch.

Zustand: near fine. from the introduction, "Geological investigations by local prospectors and explorers (Russeger, 1937) were started very early in the Democratic Republic of Sudan. The first general geological map of the Sudan was produced by Dunn (1911). In 1947, the Geological Survey published the geological map of the Sudan at 1:4,000,000 scale which was followed by two editions in 1949 and 1963." brown mailing envelope, text 10.75" x 8.75", 63 pages, professional card of Ahmed Awadalla Yassin and signed on the back, Map folded.
