حفاظت از گروههای عاملی از مراحل اجتناب ناپذیر در سنتز آلی است، در این بین محافظت از گروههای آمینی بسیار حائز اهمیت است. روشهای متعددی از قبیل فرمیله کردن، استیله کردن، محافظت بصورت boc و موارد زیاد دیگری جهت محافظت از گروههای آمینی تاکنون گزارش شده است. از طرف دیگر توسعه و کاربرد کاتالیست ها و حلالهای دوستدار محیط زیست و مزایای واکنشهای بدون حلال همچون سرعت بالای واکنش، خالص سازی آسان، کاهش آلو...

Received: June 12, 2017 Revised: October 24, 2017 Accepted: November 03, 2017 Abstract: Background and Objective: Prestressed high strength concrete pipe pile (PHC) shows brittle fracture when subjected to more than its own bearing capacity. Therefore, the non-prestressed steel bar is added to the PHC pipe pile, that is, the mixed reinforced pipe pile (PRC). The mechanical behavior of PRC group...
Abstract Piled embankments have been extensively used for high-speed rail over soft soils because of their effectiveness in minimizing differential settlement and shortening the construction period. Stress concentration ratio, defined as ratio vertical stress carried by pile heads (or caps if applicable) to that adjacent soils, is a fundamental parameter design piled embankments. In view compli...
The total substitution of traditional reinforcement in the form steel bars by fibres can be mainly found elements with favourable boundary conditions and subjected to low-moderate load levels. However, rigorous study fibre reinforced concrete (FRC) its potential fields application over last decades permitted this material face structural greater responsibility terms integrity mechanical capacit...
Application of pile-raft foundations, which are known as “compound foundations”, is a suitable alternative in the case of heavy load structures. The interaction behavior of pile raft foundations makes these systems very complex to analyze. Different methods have been proposed to determine the bearing capacity of piled raft systems and distribution of loads between the components, i.e. pile grou...
