关键词： Coronary Heart Disease   Myocardial Contrast Echocardiography   Adenosine Load   Myocardial Blood Flow Perfusion and Reserve   Coronary Flow Reserve  

摘要： To apply adenosine load combined with myocardial contrast echocardiography (MCE) to evaluate myocardial blood flow perfusion and reserve function in patients with chronic coronary heart disease (CAD), and to compare it with Fractional Flow Reserve (FFR), in order to explore the potential of MCE in assessing myocardial blood flow reserve.

关键词： 异构CAD系统   模型重构   中间引用拓扑实体   映射  

摘要： 针对异构CAD系统间交换数据重构问题,提出基于引用拓扑实体方法,将建模历史节点引用永久拓扑命名转化可准确表征的中间拓扑实体,利用中间拓扑数据对当前重构节点实体进行完整记录和精确表征,以在目标CAD系统中实现该中间引用拓扑实体到永久拓扑命名的映射,达到异构CAD系统间数据模型重构的需求。最后,所提方法已在国内某国产工业软件中得到成功的测试案例,证明了该理论的可行性。

关键词： 新文科   美育   纺织品设计  

摘要： 在新文科视域下,美育教学的调整、改善和反思有重要意义。在国家各项政策文件的指导下,纺织品设计专业美育课程有必要探索新路径。文章主要分析了纺织品设计专业美育的现状和困境,在此基础上提出了“一个核心,五个层面”的教育模式和实践路径,以促进纺织品设计专业和美育的有机融合与全面发展。

摘要： Interstitial Cystitis/ Bladder Pain Syndrome (IC/BPS) is a chronic pain syndrome of unknown cause that carries a substantial psychosocial burden. IC/BPS is characterized by constant pain and discomfort around the bladder region and some lower urinary tract symptoms such as frequent voiding and pain during urination.

关键词： 深海管线钢   热影响区   M-A组元   晶界   韧性  

摘要： 采用热模拟机模拟深海管线钢的粗晶区,并通过光学显微镜、扫描电镜、电子背散射衍射和夏比冲击试验表征了其组织和韧性,研究了二次热循环中不同峰值温度对深海管线钢粗晶区组织和韧性的影响。结果表明:当二次热循环峰值温度为800℃时,管线钢粗晶区的组织主要为粒状贝氏体,块状M-A组元在原奥氏体晶界呈现断续的链状结构,大角度晶界比例较低,冲击吸收功为37.8 J,表现出明显的脆化现象。当峰值温度为900℃时,组织主要为多边形铁素体和准多边形铁素体,大角度晶界比例较高,韧性最优。

关键词： Cam β-NGF   Dromedary camel   Sperm motility   Sperm viability   Semen preservation   Artificial insemination  

摘要： The role of camel βeta-Nerve Growth Factor protein (Cam β-NGF), isolated from camel seminal plasma, in preserving sperm quality remains poorly defined. This study aimed to evaluate the impact of Cam β-NGF on mass motility, viability, and membrane integrity in dromedary (Camelus dromedarius) semen stored for 24 hours at 4 °C.

关键词： FME技术   CAD   GIS   数据   共享  

摘要： 为了促进CAD与GIS数据的高效共享与应用,本文介绍了利用FME技术进行数据转换的方法。首先,通过CAD数据预处理确保数据质量;随后,详细探讨了分层设色、要素符号与编码标准设计,为数据转换提供了标准依据。在此基础上,本文构建了GIS数据库,并通过语义映射技术实现了CAD与GIS数据的共享。最后,对共享数据进行了质量检查,确保了数据的准确性和可靠性。研究结果表明,利用FME技术可以有效实现CAD与GIS数据共享,为地理信息数据的集成与应用提供了有力支持。

摘要： Purpose / Aim: The aim of this study was to evaluate the quality of anterior crown margins made of experimental short fiber-reinforced composite (SFRC) computer-aided design/computer-aided manufacturing (CAD/CAM) block, and to compare it with othe...

关键词： Implant overdenture   Milled bar   Locator abutment   Drill and tap technique   Duplicate working cast   Denture stabiliy  

摘要： Completely edentulous patients with extensive residual ridge resorption usually suffer from reduced chewing ability, unstable dentures, and tenderness upon occlusal loading. This case report describes the clinical and laboratory steps to fabricate a milled implant bar with locator attachments to address the complaints of lower implant overdenture instability and pain associated with a knife-edge mandibular residual ridge.
