The present work discusses the tribological performance of friction composites reinforced by natural fibers at continuous and starting - stopping tests aiming to provide specific relationship between the performances of the two tests. In the friction composites, asbestos is replaced by the tested natural fibers such as corn, palm and sugar bars. The proposed composites contain a mixture of phenolic resin (as matrix), metal powder (iron, copper, and aluminum), graphite, barium sulfate, and silica. Friction coefficient, wear, and temperature were accurately measured for the two tests...

Refining High Acid Olive Oil. The world production of olive oil reach 2,800,000 ton and 98% of this production is to be found in the Mediterranean Basin, where this agricultural system has been developing for thousands of years, characterized by its adaptation to the environment and its empiricism. Virgin olive oil is consumed unrefined, although a great proportion of the olive oil produced has to be refined to render it edible. Refining treatments are needed to remove or reduce the content of minor substances that may affect oil quality, such as phospholipids, FFA, pigments, peroxides,...

This is a concise well illustrated and easy to read book. It is written in a simple way and should be useful to consultant pediatric surgeons, general surgeons, fellows, specialists, residents and nurses as well as pediatricians and neonatologists. The book covers most areas in pediatric surgery and pediatric urology with emphasis on the most important points relevant to the patient's management including clinical, operative, radiological, histological and hand drawn illustrations.
