Tests of the capacity of shear connections consisting of nails in a row placed at distances 7, 10 and 14d, “d” being the cross-sectional dimension of the nail, versus single nail capacities, were executed. The performed tests do support the connotation that no reduction should be required for nails of diameter 2.8 mm or less in a row, provided that nails are spaced sufficiently far apart for wood cracking not to occur. At the ultimate capacity of the joint, all such thin nails in a row will be yielding, having developed plastic hinges, i.e. each single nail will have developed its ultimate capacity. Hence, the ultimate capacity of the connection will be each nail’s capacity times the number of nails in the row. The force pr. nail increases subsequent to the development of a plastic hinge. This is likely due to the axial pullout-force, i.e. the ultimate capacity of a shear connection is higher than the force required for developing plastic hinges in the nails. This additional capacity-reserve may also partly be attributed to the rotational resistance of nails. The number of nails in a row should make insignificant difference in the pr. nail capacity, as long as no wood cracking takes place. Thus, applying elastic theory to nails in a row does not seem relevant. This is in contrast to bolt-connections.

Observed weather and projected climate change suggest an increase in the transmission of vector-borne diseases(VBDs)in the Hindu Kush Himalayan(HKH)*** this study,we systematically explore the literature for empiric associations between the climate variables and specific VBDs and their vectors in the HKH *** conducted a systematic synthesis of the published literature on climate variables,VBDs and vectors in the HKH region until the 8th of December *** majority of studies show significant positive associations of VBDs with climatic factors,such as temperature,precipitation,relative humidity,*** systematic review allowed us to identify the most significant variables to be considered for evidence-based trend estimates of the effects of climate change on VBDs and their vectors in the HKH *** evidence-based trend was set into the context of climate change as well as the observed expansion of VBDs and disease vectors in the HKH *** geographic range of VBDs expanded into previously considered non-endemic areas of highlands(mountains)in the HKH region.B ased on scarce,but clear evidence of a positive relationship of most climate variables and VBDs and the observed climatic changes,we strongly recommend an expansion of vector control and surveillance programmes in areas of the HKH region that were previously considered to be non-endemic.

目的研究加味桃红四物汤对体外培养的人表皮黑素细胞(MC)可溶性总蛋白以及酪氨酸酶(Tyr)基因和酪氨酸激酶受体基因(c-kit)表达的作用。方法采用免疫印迹法检测了加味桃红四物汤对酪氨酸酶和酪氨酸激酶受体蛋白含量的影响;595nm比色标准曲线测定黑素细胞总蛋白含量;采用细胞数统计和显微镜观察的方法测定加味桃红四物汤对细胞毒性和对细胞增殖的影响。结果加味桃红四物汤对黑素细胞可溶性总蛋白和酪氨酸酶的合成有促进作用,分别为4.76%和1.79%;对酪氨酸激酶受体蛋白的合成具有显著促进作用,高达79.41%。结论加味桃红四物汤治疗白癜风的作用机制之一是与酪氨酸激酶受体蛋白含量的提高相关,而与黑素细胞增殖和酪氨酸酶相关蛋白的含量无明显关系。

Open Journal of Anesthesiology 2017年第4期7卷 69-82页

Background: Omission of patient information in perioperative communication is closely linked to adverse events. Use of checklists to standardize the handoff in the post anesthesia care unit (PACU) has been shown to effectively reduce medical errors. Objective: Our study investigates the use of a checklist to improve quantity of data transfer during handoffs in the PACU. Design: A cross-sectional observational study. Setting: PACU at Memorial Sloan Kettering Cancer Center (MSKCC);June 13, 2016 through July 15, 2016. Patients, other participants: We observed the handoff reports between the nurses, PACU midlevel providers, anesthesia staff, and surgical staff. Intervention: A physical checklist was provided to all anesthesia staff and recommended to adhere to the list at all observed PACU handoffs. Main outcome measure: Quantity of reported handoff items during 60 pre- and 60 post-implementation of a checklist. Results: Composite value from both surgical and anesthesia reports showed an increase in the mean report of 8.7 items from pre-implementation period to 10.9 post-implementation. Given that surgical staff reported the mean of 5.9 items pre-implementation and 5.5 items post-implementation without intervention, improvements in anesthesia staff report with intervention improved the overall handoff data transfer. Conclusions: Using a physical 12-item checklist for PACU handoff increased overall data transfer.
