background: monte carlo simulations play a vital role in the calculation of the necessary shielding both for neutrons and photons. advanced and simple shielding materials against neutron and gamma rays were compared by simulation using the mcnb4b monte carlo code. the simulations were carried out for the three common neutron sources, namely the 252cf, the 241am/be and the dd neutron generator w...

Abstract Aim National reported mastectomy rate varies from 25% - 45%. Also, when a reduction therapeutic mammoplasty is needed, symmetrisation of the contralateral side will follow. Can “relative new” technique local perforator flaps, reduce volume mastectomies and surgery in District General Hospital? Method Retrospective review yearly breast cancer treatment operations Ipswich Hospital. Resul...

permanent magnet synchronous motors are efficient motors, which have widespread applications in electric industry due to their noticeable features. one of the interesting applications of such motors is in underwater vehicles. in these cases, reaching to minimum volume and high torque of the motor are the major concern. design optimization can enhance their merits considerably, thus reduce volum...

children, similar to adults, are required to fast before general anesthesia in order to reduce  the volume and acidity of stomach contents. it is thought that npo regulations reduce the risk of regurgitation and aspiration of gastric contents during surgery. recent developments have encouraged a shift from the standard 'nil by mouth from midnight' fasting policy to more relaxed regime...

economic and environmental logging is important for sustainable wood production in the caspian forests, north of iran. predetermination of the skid trail network and directional felling is a usual recommended method to reduce logging impact. the aim of this study was evaluation of directional felling and finding factors effective on felling error. totally 135 trees were selected randomly for di...

Philologists assure us that it’s worth learning ancient Greek just to read Homer. For any linguist, it’s definitely worth learning French, just to read Lucien Tesnière’s Elements de Syntaxe Structurale (Tesnière 1959). For any serious dependency parsing student or professional, it would have been worth learning Swedish, just to read Joakim Nivre’s Inductive Dependency Parsing if Nivre had not d...
