Social participation challenges and response strategies identified by adults aging with a disability
Journal of Elder Policy, Volume 3, Issue 2, Page 95-109, October 2024.Abstract Social participation is likely to decrease among older adults as disability levels increase. However, it is a modifiable determinant of health that can impact older adults' well‐being and quality of life. Thus, this secondary data analysis aimed to understand what challenges older adults aging with a mobility or vision disability face with ...

Gaoya dianqi, 1995 研究了CuCr和CuCrWC真空触头合金老炼过程中表层组织形成的特点。研究表明老炼过程主要造成合金表面熔化层组织细化和成分均匀化,从而使耐电压强度升高。在CuCr合金加入WC可以提高其耐电压强度。本文还讨论了电流大小对电压老炼过程的影响。

Reforming the Dutch pension system to ensure sustainability
International Social Security Review, Volume 77, Issue 3, Page 99-122, July/September 2024.Abstract The Netherlands is on the brink of reforming its system of occupational pensions as part of a more general reform of its three‐pillar pension system. This reform features important changes to first pillar pension benefits. The focus of this article is however on the coming reform of occupational pensions, the second pillar of the system, which

The use of health services by women living homeless in Madrid, Spain
Poverty &Public Policy, Volume 16, Issue 2, Page 172-181, June 2024.Abstract Women living homeless make up a particularly vulnerable and significantly invisible collective, about which there is little information regarding the use of health services. The purpose of this study is to examine the use of health services by a sample of women living homeless in Madrid, Spain (n = 138).

Gaoya dianqi, 2012 温度是油纸绝缘老化的主要因素。笔者设计了油浸式电力变压器常用的普通牛皮纸和环烷基矿物油复合绝缘在90℃下长达370 d的热单因子老化试验。利用XRD（X射线衍射）定期测量不同老化状态的绝缘样品,对比分析了绝缘纸的聚态结构的变化情况,并深入讨论绝缘纸聚合度下降的动力学过程。研究结果表明:绝缘纸在老化过程中,纤维素氢键和糖苷键发生断裂,引起聚合度下降,结晶区遭受破坏,晶粒尺寸减小,导致纤维素分子间作用力减弱,热裂解活化能降低;老化过程中,绝缘纸纤维素晶体类型不变,聚合度的下降规律符合二阶动力学模型 ...

Gaoya dianqi, 2004 向低密度聚乙烯中添加自由基清除剂能够有效地抑制电老化,因而改变了电老化过程中聚乙烯的空间电荷的分布。在直流预压和短路过程中,空间电荷量随老化时间呈线性增长。结合自由基清除剂在其它老化形式中的化学反应机理,详细讨论了自由基清除剂对聚乙烯电老化的抑制以及老化过程中空间电荷分布的影响。

, 2013 本研究探討利用離子交換法製備鈷觸媒，並研究製備配方不同時，對硼氫化鈉水解產氫之動力學參數研究。鈷觸媒製備過程分為兩步驟，以陽離子交換樹脂作為觸媒載體進行鈷離子交換，再以還原劑將鈷離子還原在樹脂載體上形成金屬態之觸媒。觸媒製備之參數為：陽離子交換樹脂種類、離子交換時間、還原劑濃度、還原劑添加速率、還原劑pH值。而離子交換時間以量測pH值來確定離子交換已達到飽和容量，在後離子交換10分鐘後pH值達0.5趨於穩定離子交換達飽和。使用硼氫化鈉作為還原劑，還原劑添加的濃度影響觸媒的附載量 ...
