Background: The purpose of this study was to assess the dose distribution and coverage of level Ⅰ-Ⅱ axillary lymph nodes during whole breast tangential field radiotherapy (RT) after breast-conserving surgery in patients with breast cancer. Materials and Methods: The level Ⅰ-Ⅱ axillary lymph node volumes were retrospectively contoured by a single radiation oncologist based on computed tomography...

The use of reverse transcription (RT) PCR for relative quantitation of gene transcripts relies on the reproducibility of the individual RT, PCR and product measurement steps. Semi-competitive RT-PCR (RT-cPCR) uses an internal competitor template in the PCR step to improve quantitation. We have surveyed the reproducibility of RT, PCR, RT-cPCR and measurement, amplifying the glyceraldehyde-3-phos...

Even though real-time systems have the stringent constraint of completing tasks before their deadlines, many existing real-time operating systems do not implement fault tolerance capabilities. In this paper we summarize fault tolerant real-time scheduling policy for dynamic tasks with ready times and deadlines. Our focus in this paper is the implementation, which includes fault-tolerant schedul...

Background and Aims: The causal agents of viral lettuce big vein disease are two viruse, Lettuce big vein associated virus (Varicosavirus) and Mirafiori lettuce virus (Ophiovirus). These viruses have coat proteins of similar size but have different morphologies and serologically unrelated.The purpose of this study was to distinguish and detect LBVaV and MiLV in lettuce fields in Tehran Province...

Background: The High Intensity Interval Training (HIIT) has had space in social networks that disseminate its practice and also among practitioners of physical exercises a global way. Objective: To verify if the stimuli order (HIIT-RT or RT-HIIT) changes acute hemodynamic response. Methods: 10 young adult male participants aged between 18 30 years (24.7 ± 2.2). For test protocols intensity inte...

the aim of this study was to evaluate the effect of long-term reduced tillage on yield and weeds of spring barley. treatments consisted of three tillage systems including: (a) conventional tillage (ct), (b) reduced tillage (rt), and (c) herbicide tillage (ht) as the main plot, and two cultivars of spring barley (tocada and rastik) as subplots. the results showed that the yield of both cultivars...
