Objective: This paper aims to explore the impact of optimizing details in the operating room on the level of knowledge, attitude, and practice of hospital infection prevention and control by surgeons, as well as the effectiveness of infection control. Methods: From January 2022 to June 2023, a total of 120 patients were screened and randomly divided into a control group (routine care and hospital infection management) and a study group (optimizing details in the operating room). Results: Significant differences were found between the two groups in the data of surgeons’ level of knowledge, attitude, and practice in hospital infection prevention and control, infection rates, and nursing satisfaction, with the study group showing better results (P Conclusion: The use of optimizing details in the operating room among surgeons can effectively improve surgeons’ level of knowledge, attitude, and practice in hospital infection prevention and control, reduce infection occurrence, and is worth promoting. 展开更多

An original reinforced concrete(RC) column and four strengthened specimens, two with RC jackets and two with wing walls, were tested in this study. The original column specimen was designed to comply with older(pre-1999) design standards so that the usual detailing defi ciencies in existing school buildings in Taiwan could be simulated. Two different structural details were chosen to fabricate the full-scale specimens for each retrofi tting technique. The study confi rmed that either RC jacketing or the installation of wing walls with two different structural details can effectively improve the stiffness and strength of an existing column. RC jacketing shows a better improvement in energy dissipation and ductility when compared to the columns with wing walls installed. This is because the two RC jacketed columns experienced a fl exural failure, while a shear failure was found in the two columns with the wing walls installed, and thus led to a drastic decrease of the maximum lateral strengths and ductility. Since many factors may affect the installation of a post-installed anchor, it is better to use standard hooks to replace post-installed anchors in some specifi c points when using RC jacketing or installing wing walls. 展开更多

To study the fatigue performance of welded details in the orthotropic steel decks,the steel box girder for Taizhou Yangtze River Bridge is taken as the research object.Based on the field monitoring data obtained from the load test,the stress response test of the orthotropic steel box girder under wheel loads is performed and the correctness of the vehicle test data obtained from the field monitoring data also have been verified by the numerical results of the finite element model.Based on the Miner linear cumulative damage theory,the S-N curve of the Eurocode3 specification is referenced,and the fatigue life calculation formula of the welded details is determined according to the actual structural features.The fatigue life evaluation of the four typical welded details is obtained.The results indicate that:The load test data is compared and verified by the numerical result of finite element model.The local effect of stress distribution is remarkable.The stress measurement points on the four typical welded details are mainly based on low amplitude stress cycles.Most of the stress ranges are 2-10 MPa,among which the stress range of the welded details at the U-rib butt joint is larger.The fatigue life of welded details in the 14 mm thick top plate is smaller than that of the 16 mm thick top plate corresponding to the fatigue life of the welded details.The rib-to-rib butt welded joints and the openings of the diaphragms were prone to fatigue failure.Among them,the welding details of the 14 mm thick U-rib butt joints first appeared fatigue failure.The arrangement of the diaphragm can effectively increase the fatigue life of the top-U rib weld and improve the fatigue performance at this detail. 展开更多

Four types of seismic design details were tested using 11 transfer column specimens and one comparison specimen of RC under low cyclic reversed loading. Test results show that diagonal cracks control the failure pattern and damage occurs mainly in the RC section with weak shear capacity in the transfer columns. There is a large difference in the bearing capacity and ductility of the transfer columns according to the test results, which indicates that the strengthening effect of diverse structural measures is quite different. The section ratio of I-section-encased steel and the axial compression ratio also have a great influence on the bearing capacity and ductility. Although the bearing capacity of transfer columns with additional longitudinal bars and additional X bars is relatively large, they have poor deformation capacity. Setting more stirrups along the columns is the best structural measure to enhance the seismic performance. The studs on the I-sectionencased steel by welding can help to complete the stress transfer between the steel and concrete, and avoid performance degradation of the two materials due to bonding failure. 展开更多

In order to study the fatigue properties of rib-to-deck welded connection and rib-to-rib welded connection in orthotropic steel bridge decks,a multi-scale finite element model was set up to analyze the stress distribution characteristics and the load test was conducted on the Taizhou Yangtze River Bridge.Comparing the vehicle test results with the muli-scale finite element model results to verify the accuracy of the finite element simulation for the stress response of two welded details.The results indicated that The stress at the rib-to-deck welded connection and the rib-to-rib welded connection are the bending stress and the membrane stress,respectively;the stress response of the two welded connection has strong local characteristics;the lateral stress influence line of the two welded connection is relatively short and the length of the lateral stress influence line is greatly affected by the longitudinal ribs;increasing the thickness of the roof and longitudinal ribs can reduce the stress response and improve the stress performance of the heavy lanes.For the two welded details,the fatigue damage increment of the ordinary lane is greater than the heavy lane.The thickened roof and longitudinal ribs at the position of the heavy lane still cannot balance the fatigue damage caused by the heavy truck.Therefore,it is necessary to strictly control the fatigue effect of overloaded vehicles on steel box girders. 展开更多

At present, the most important part of Chinas infrastructure is the road and bridge project, which has a significant impact on social traffic and has played a positive role in the development of the whole society. However, the road and bridge engineering is very complicated, and it is bound to encounter various problems. Relevant personnel must pay attention to the construction technology and improve the construction quality. Specifically, relevant personnel should strictly implement relevant codes and technical standards, strictly follow the construction principles, strengthen the quality monitoring of road and bridge construction, and effectively extend the service life of road and bridge. Before construction, relevant design work must be done first, and then the details of various construction technologies should be optimized. If the construction technology is not properly selected, it will involve many quality problems of road and bridge, and even shorten the service life. Therefore, in the process of road and bridge construction, technicians need to solve the details of existing construction techniques in time to improve traffic safety. 展开更多

Osteoblasts are essential in the maintenance of human bone homeostasis.1 The abnormal formation and impaired differentiation ability of osteoblasts are pivotal factors leading to bone-related diseases,suggesting that an indepth study of osteoblasts can provide novel treatment strategies for these diseases.2 Human primary osteoblasts are precious experimental models in bone-related research.3 However,the isolation and culture of human primary osteoblasts still have some difficulties and limitations.Here,we refined a method to isolate and culture human primary osteoblasts by taking cancellous bone through a bone tissue sampler and pre-digesting it with pancreatin,which makes the process easier,cheaper,and more efficient.Furthermore,we compared the effects of the subtle changes in isolation and culture methods on the phenotype of human primary osteoblasts and examined the differences in morphology,proliferation,and differentiation between micro-explants cultured osteoblasts(MECOBs)and explants cultured osteoblasts(EC-OBs). 展开更多
