This program has attempted to increase the effectiveness of learning experiences offered teachers in their continuing edu cation by making available to these learn ers the opportunity to assume responsi bility for thei...
اهمیت اندازه گیری قلع در ورقهای قلع اندود بدلیل استفاده از ورقهای فوق در سات ظروف کنسرو مواد غذایی امروزه مورد توجه زیادی قرار گرفته است. در این بررسی با توجه به اثر اعمال جریان در لایه برداری قلع، روشی جهت اندازه گیری ضخامت لایه قلع در ورقه های تولیدی ارائه شده است که مبتنی بر استفاده از روش کرنوپتانسیومتری میباشد. در این مطالعه زمان مورد نیاز جهت لایه برداری در جریان ثابت اعمال شده با ضخامت ق...
The application of a higher corrosion resistance coating modified with nano additions can effectively decrease or prevent from occurring. In the present work, novel method is successfully developed for modification carbon steel surfaces aiming high using Sn—4% Zn alloy/nanoparticle composite (NiO+ Al2O3) coating. coatings were deposed on direct tinning process that involved power mixture alloy ...

Intensive technological process of hop growing traditionally supposes withholding spaces between rows plantations free vegetation due to the interrow cultivating. It results in disruption natural reproduction soil fertility, and a decrease stability functioning productivity agrobiocenosis. In problem humulocenosis constancy home foreign scientists partly decide by green manure rows. makes it po...
The failure mechanism was determined to be tin whiskers emanating from the tin plating on the internal pins. The high conductivity, pure tin crystalline whiskers bridged the 10-mil spark gap to cause the test failures. The fusing current of the whiskers was in the range of the source current of the test equipment. This caused inconsistencies during problem identification and verification at the...
