Background Brucellosis is a severe zoonotic disease that is often overlooked, particularly in impoverished countries. Timely identification of focal complications in brucellosis is crucial for improving treatment outcomes. However, there is currently a lack of established indicators or biomarkers for diagnosing these complications. Therefore, this study aimed to investigate potential warning signs of focal complications in human brucellosis, with the goal of providing practical parameters for clinicians to aid in the diagnosis and management of *** A multi-center cross-sectional study was conducted in China from December 2019 to August 2021. The study aimed to investigate the clinical characteristics and complications of patients with brucellosis using a questionnaire survey and medical record system. The presence of warning signs for complications was assessed using univariate and multivariate logistic regression models. Receiver operating characteristic (ROC) curves and the area under the curve (AUC) were used for variable screening and model *** A total of 880 participants diagnosed with human brucellosis were enrolled. The median age of the patients was 50 years [interquartile range (IQR): 41.5-58.0], and 54.8% had complications. The most common organ system affected by complications was the osteoarticular system (43.1%), with peripheral arthritis (30.0%), spondylitis (16.6%), paravertebral abscess (5.0%), and sacroiliitis (2.7%) being the most prevalent. Complications in other organ systems included the genitourinary system (4.7%), respiratory system (4.7%), and hematologic system (4.6%). Several factors were found to be associated with focal brucellosis. These factors included a long delay in diagnosis [odds ratio (OR) = 3.963, 95% confidence interval(CI): 1.906-8.238 for > 90 days], the presence of underlying disease (OR = 1.675, 95%CI: 1.176-2.384), arthralgia (OR = 3.197, 95%CI: 1.986-5.148), eye bulging pain (OR = 3.482, 95%CI:

为了验证能量分布模式对异种铝合金焊接质量的影响,采用全域功率调制激光振镜焊接系统对6061和5052铝合金进行了对接焊试验.对比了传统激光焊(lW)和两种激光振镜焊接模式(恒功率-CP和梯度功率-GP)对焊缝成形、焊接气孔、显微组织和力学性能的影响.结果表明,光束振荡改善了焊缝成形,GP模式焊缝表面凹陷程度最小;振镜模式下焊缝等轴晶的比例比激光焊增多,其中GP模式焊缝等轴化程度最高,显示出最高的接头强度和熔合区硬度;GP模式焊接时降低了熔池温度梯度,使熔池产生了最大的过冷度和异质形核率,从而提高了焊缝中等轴晶的比例;振镜激光焊接改变了能量分布模式,降低了能量峰值;GP模式下焊缝中心的能量密度高于CP模式,使得焊缝熔合良好.

为揭示分流叶片对低比转速液力透平性能的影响,以一台低比转速离心泵(n_(s)=33)反转作液力透平为例,设计出4种不同分流叶片数的叶轮(复合叶轮),通过CFX软件对原始叶轮和4种复合叶轮进行数值模拟并对比分析。结果表明,4种新模型在最优工况下效率和水头均有所提高,其中当分流叶片数Z=6+6时液力透平的性能最佳,在最优工况下效率、水头分别提高了2.23%、6.83%;叶轮内压力分布更加均匀;叶轮进口漩涡区域减弱;内部各个监测点压力系数、脉动幅值均小于原始模型,说明分流叶片可以降低液力透平内部的压力脉动、提升透平机组运行的稳定性。研究结果可为低比转速液力透平性能提升提供参考。
