This paper presents a novel 1-DOF (degree-of-freedom) single-loop reconfigurable 7R mechanism with multiple operation modes (SLR7RMMOM), composed of seven revolute (R) joints, via adding a revolute joint to the overconstrained Sarrus linkage. The SLR7RMMOM can switch from one operation mode to another without disconnection and reassembly, and is a non-overconstrained mechanism. The algorithm fo...

background craniosynostosis results from premature closure of one or more cranial sutures, leading to deformed calvaria and craniofacial skeleton at birth. postoperative complications and outcome in intensive care unit (icu) is related to surgical method and perioperative management. this study determined the perioperative risk factors, which affect outcome of patients after craniosynostosis su...

this research, in addition to survey the existing data on the quality of sahebgharanieh wastewater treatment plant's effluent in the previous years, by runing a three months monitoring stage, studies the conditions of the final settling and aeration basin and the variations of the influent and effluent quantity and quality in removing of major pollutants (bod, cod, tss), while scrutinizing the ...

The mechanism of message active transmission from WEBGIS server based on the N-layer architecture of Internet has been studied and realized in this paper. In the WEBGIS application of facing long business operation as well as showing server information in the client in real-time, Socket communication mechanism and the client combined with JAVA Applet technology are used to realize the message a...

Femtocell technique has become a radical approach to improve network capacity and coverage. To efficiently reduce interference between femto BS and other BSs, low duty operation mode (LDM) is deemed as a good method to mitigate the interference. In this work, we develop a mechanism that incorporates the power saving mechanism in both femto BS (LDM mode) and MSs (sleep mode). To correspond to th...

to determine the factors affecting the outcome of patients with traumatic acute subdural hematoma, we reviewed the records of7 4 consecutive comatose patients with a glascow coma scale score (gcs) of less than 8 who had been admitted to imam hosein medical center from 1990 to 1996 and had undergone a uniform treatment protocol. the overall mortality rate was 73% and 23% had functional recovery,...
