1Innovative hybrid reinforcement constituting conventional longitudinal steel and FRP stirrups for improved seismic strength and ductility of RC structures显示文摘纤维的使用增强的聚合物(FRP ) 加强在新结构的建设正在变得逐渐地吸引人。然而,当重要材料无弹力被要求通过 hysteretic 周期浪费输入体力时,直到破裂的 FRP 材料的固有的线性有弹性的行为在地震攻击下面被看作一个主要缺点。而且,花去考虑,包括 FRP 材料和预制 FRP 的建设配置,特别为马镫,和环氧基树脂的可能的损坏涂的纤维什么时候搬运了到这块地,是显著问题。当前的研究为实现由 FRP 表组成的所在地的制作 FRP 马镫的基础结构的下一代建议了一个新奇节俭的混合加强计划。混合加强由常规纵的钢加强和 FRP 马镫组成。建议混合加强的特色由于 FRP 马镫提供给纵的钢加强和核心水泥的可观的限制压力是提高的力量和韧性。增强的具体横梁标本和 beamcolumn 关节标本被测试实现建议混合加强。,与常规钢马镫相比建议了混合加强,被发现有更高的力量,僵硬,和精力驱散。建议混合加强的设计方法,结构的行为,和适用性在这篇论文详细被讨论。Mostafa FAKHARIFAR Ahmad DALVAND Mohammad K.

2Analysis of factors affecting diagonal tension and compression capacity of corner joints in furniture frames fabricated with dovetail key显示文摘This study was conducted to analyze the effect of joint type, and numbers and types of dovetail keys on diagonal tension and compression performance of corner joints in a furniture frame. Joint members were cut from white fir lumber. Butted and mitered joints were constructed with one and two dovetail key(s) with butterfly and H shapes. Joints were glued by polyvinyl acetate (PVAc) and cynoacrylate (CA). Compression capacity of joints was higher than diagonal tension. Mitered joints were stronger than butted ones. Butterfly dovetail keys were superior to H shape keys. Double keys performed better than single key. Experimental joints glued with PVAc were stronger than those glued with CA glue and control specimens. In terms of strength, butterfly dovetailed joints were comparable with doweled joints.Mosayeb Dalvand Ghanbar Ebrahimi Akbar Rostampour Haftkhani Sadegh Maleki 2013Journal of Forestry Research2013,24,1:2
3机器人辅助微创手术系统的触诊功能实验显示文摘机器人辅助微创手术系统中的触诊功能的实现对提高手术效率,减少术中对非病变组织的创伤有重要意义。针对已研制的机器人辅助微创手术系统中的触诊模块进行性能测试,一是用于测量微器械在手术中夹持器官组织时产生的夹持力的夹持力测量系统,一是用于测量微器械与非夹持器官组织接触时产生的相互作用的接触力的接触力测量系统。通过实验分析了系统的精度和性能,为系统的进一步优化提供依据。李云峰 Bijan Shirinzadeh 沈惠平 Mohesn Moradi Dalvand 2018机械设计与研究2018,34,4:2
4Bending moment resistance of dowel corner joints in case-type furniture under diagonal compression load显示文摘We investigated bending moment resistance under diagonal compression load of corner doweled joints with plywood members. Joint members were made of 11-ply hardwood plywood of 19 mm thickness. Dowels were fabricated of Beech and Hornbeam species. Their diameters(6, 8 and 10 mm) and depths of penetration(9, 13 and 17 mm) in joint members were chosen variables in our experiment. By increasing the connector's diameter from 6 to 8 mm, the bending moment resistance under diagonal compressive load was increased, while it decreased when the diameter was increased from 8 to 10 mm. The bending moment resistance under diagonal compressive load was increased by increasing the dowel's depth of penetration. Joints made with dowels of Beech had higher resistance than dowels of Hornbeam. Highest resisting moment(45.18 N·m) was recorded for joints assembled with 8 mm Beech dowels penetrating 17 mm into joint members Lowest resisting moment(13.35 N·m) was recorded for joints assembled with 6 mm Hornbeam dowels and penetrating 9 mm into joint members.Mosayeb Dalvand Ghanbar Ebrahimi Mehdi Tajvidi Mohammad Layeghi 2014Journal of Forestry Research2014,25,4:1

20Relationship between using cell phone and the risk of accident with motor vehicles:An analytical cross-sectional study显示文摘Purpose Traffic accidents are one of the major health problems in the world,being the first cause of burden of illness and the second leading cause of death in Iran.The Sistan-Baluchestan province is one of the most accidental provinces of Iran with the highest rate of accidents-caused deaths.This study was conducted to determine the risk factors associated with traffic accidents in Zahedan through 2013 to 2016.Methods This analytical cross-sectional study was carried out on 223 drivers from Zahedan who were traumatized by traffic accident and sent to Zahedan hospitals.The data were obtained through interviews taken by the trained interviewers via refereeing to the medical records and collected in the researcher-made checklist.Census was obtained from the study subjects.For data analysis,independent t-test,one-way ANOVA,Chi-square and logistic regression were used with the Stata software version 11.0.Results In this study,223 male subjects with the mean age of(32.54±12.95)years,39.8%single and 60.2%married,entered for investigation.Most accidents(38.8%)occurred between 12:00 to 17:59.While driving,47.1%of the study subjects were using cell phones,89.1%had manual use of mobile phones,21.9%had a habit of sending short message service(SMS)and 23.4%had sent SMS within 10 min before the accident.The one way analysis of variance showed that the mean age of individuals with marital status,driving experience,education and accident with motorcycle were significantly different(p<0.05).Also,the multivariate logistic regression test indicated a significant relationship of smoking,ethnicity,insurance and SMS typing while driving with motorcycle accident(p<0.05).Conclusion In this study,SMS and smoking while driving had the highest risk among the variables studied in the motorcycle accidents.Therefore,effective education attempting to enhance people's awareness about the consequences of using cell phone and smoking during driving to reduce traffic accidents seems necessary.Mohammad Kogani Seyed Ahmad Almasi Alireza Ansari-Mogaddam Sahar Dalvand Hassan Okati-Aliabad Seyed Mehdi Tabatabaee Seyedeh Zeinab Almasi 2020Chinese Journal of Traumatology2020,23,6:0
