1尿钠排泄、血压、心血管病与死亡率的关系:社区前瞻性流行病学队列研究显示文摘WHO建议人群钠摄人<2 g/d作为预防心血管病的措施之一,但这一目标在任何国家都没有实现。该建议主要基于短期血压试验的个体水平数据,没有来自随机试验或观察性研究的关于低钠摄入与降低心血管事件的数据。前瞻性城市农村流行病学研究目前正在21个国家进行。该文对其中18个国家的数据进行分析,其中包含了临床结果数据。Mente A O'Donnell M Rangarajan S McQueen M Dagenais G Wielgosz A Lear S Ah STL Wei L Diaz R Avezum A Lopez-Jaramillo P Lanas F Mony P Szuba A Iqbal R Yusuf R Mohammadifard N Khatib R Yusoff K Ismail N Gulec S Rosengren A Yusufali A Kruger L Tsolekile LP Chifamba J Dans A Alhabib KF Yeates K Teo K Yusuf S 刘莉 叶鹏 2018中华高血压杂志2018,26,12:29

3用于个人护理品的多功能、卓越高效的阳离子纤维素聚合物显示文摘聚季铵盐-10是阳离子纤维素聚合物的通用名称,应用于香波体系,提供头发调理性能。聚季铵盐-10与大部分表面活性剂相容提供极好的香波透明度。在洗涤、冲洗的香波稀释过程中,阳离子纤维素聚合物和阴离子、两性表面活性剂系统形成络合物,从体系溶液中相分离出来。这种相分离(或凝聚)通常被称为“Lockhead效应”。凝聚物为胶状相,含有大量阳离子电荷,将聚合物附着在负电荷头发表面,形成透明膜。同时,凝聚帮助不溶活性成分,如硅油的附着。近期的研究显示,阳离子纤维素聚合物的黏度和电荷密度是决定香波特性,如调理性能的重要因素。凝聚物的类型因配方中使用的阳离子聚合物和表面活性剂体系而不同。选择适当的聚合物和表面活性剂体系,配方者可预计和控制阳离子聚合物和不溶性活性成分的附着效果。李永健 苏珊 LP乔丹 2003日用化学品科学2003,26,3:14

14Design and dynamic analysis of integrated architecture for vibration energy harvesting including piezoelectric frame and mechanical amplifier显示文摘Vibration energy harvesters(VEHs) can transform ambient vibration energy to electricity and have been widely investigated as promising self-powered devices for wireless sensor networks, wearable sensors, and applications of a micro-electro-mechanical system(MEMS). However, the ambient vibration is always too weak to hinder the high energy conversion efficiency. In this paper, the integrated frame composed of piezoelectric beams and mechanical amplifiers is proposed to improve the energy conversion efficiency of a VEH. First, the initial structures of a piezoelectric frame(PF) and an amplification frame(AF) are designed. The dynamic model is then established to analyze the influence of key structural parameters on the mechanical amplification factor. Finite element simulation is conducted to study the energy harvesting performance, where the stiffness characteristics and power output in the cases of series and parallel load resistance are discussed in detail. Furthermore, piezoelectric beams with variable cross-sections are introduced to optimize and improve the energy harvesting efficiency. Advantages of the PF with the AF are illustrated by comparison with conventional piezoelectric cantilever beams. The results show that the proposed integrated VEH has a good mechanical amplification capability and is more suitable for low-frequency vibration conditions.Xiangjian DUAN Dongxing CAO Xiaoguang LP Yongjun SHEN 2021Applied Mathematics and Mechanics(English Edition)2021,42,6:2
