Y对挤压Mg-6Gd-xY合金组织及性能的影响     

李晓航  陈琪  王海瑞  单聪 《环球赛鸽科技》2015,(13)

本文研究了钇对挤压Mg-6Gd-xY合金的显微组织、时效析出以及常温拉伸性能的影响。结果表明,添加稀土元素Y之后,合金的挤压态组织得到细化,但时效态组织细化不明显,时效后形成镁的稀土相Mg(Gd,Y)的强化相,使抗拉强度提高34~81MPa;合金的显微硬度随Y含量增加提高20HV,时效峰值的出现时间因Y的添加提前35h。  相似文献

Tai Ji Quan for the aging cancer survivor: Mitigating the accelerated development of disability,falls, and cardiovascular disease from cancer treatment     

《运动与健康科学(英文)》2014,3(1):52-57

Currently there are more than 13.7 million cancer survivors living in the U.S., and that figure is projected to increase by 31% in the next decade, adding another 4 million cancer survivors into the healthcare system. Cancer is largely a disease of aging, and the aging of the population will sharply raise the proportion of older cancer survivors, many of whom will be long-term survivors (5+ years post diagnosis). This review will address the potential utility of exercise to address three health problems that are of particular concern for the aging cancer survivor and the healthcare system, i.e., disability, falls, and cardiovascular disease, because the development of these age-related problems may be accelerated by cancer treatment. While there are many different modes of exercise that each produce specific adaptations, Tai Ji Quan may be a particularly suitable strategy to mitigate the development of age- and cancer-treatment-related problems. Based on studies in older adults without cancer, Tai Ji Quan produces musculoskeletal and cardiometabolic adaptations and is more easily performed by older adults due to its low energy cost and slower movement patterns. Since cancer survivors are mostly older, inactive, and often physically limited by the lingering side effects of treatment, they need to engage in safe, practical, and effective modes of exercise. The dearth of published controlled trials examining the efficacy of Tai Ji Quan to mitigate cancer-treatment-related musculoskeletal and cardiovascular side effects points to ample research opportunities to explore the application of this non-Western exercise modality to improve long-term outcomes for aging cancer survivors.  相似文献   

A Time of Transition     

《Journal of Teaching in Social Work》2013,33(1-2):211-219

Abstract

This narrative describes, from a personal perspective, the aging and dying processes of a social worker's parents, and the impact that this process had on her teaching in the area of social work practice and gerontology. The impact of a personal crisis on one's professional role is dramatic. Issues related to social support, the conflict inherent in multiple roles, and the burdens and joys of caretaking are explored in an effort to offer readers the opportunity to understand the complexities of the aging process. Furthermore, the dilemmas inherent in teaching about a topic that has such important and personal implications for teachers and learners are examined.  相似文献

Innovative Experiential Learning Activities in Aging: The Experiences of Four BEL Projects     

Kristina M. Hash  Jay Poole  Melissa Floyd  Crystal Dea Moore  Anissa T. Rogers  Leslie E. Tower 《Journal of Teaching in Social Work》2017,37(2):156-170

The BSW Experiential Learning (BEL) Program aims to infuse intergenerational content into the curriculum and recruit students to the field of social work by implementing face-to-face learning opportunities with older adults. This article discusses and compares the experiences of 4 diverse BEL projects that implemented gero-experiential learning activities into 1 or more of the BSW curriculum areas: introduction/social work practice, social welfare policy, human behavior in the social environment, social work research, and field practicum. “Three keys to success” are offered as ways in which gero-experiential activities may be successfully implemented by other programs.  相似文献

板茗荷在三疣梭子蟹和锯缘青蟹体上的附着及种群特征     

薛俊增  邵晓阳  吴惠仙 《科技通报》2003,19(2):87-89

研究舟山海域三疣梭子蟹和香港海域锯缘青蟹、三疣梭子蟹体上附着的板茗荷,发现舟山海域三疣梭子蟹体上只有蟹板茗荷附着,而香港海域三疣梭子蟹体上附着的板茗荷有心板茗荷、角板茗荷和蟹板茗荷,锯缘青蟹体上仅附着有心板茗荷.板茗荷主要附着于蟹步足的侧鳃、螯肢的关节鳃及第三颚足的关节鳃上,且全附着于鳃的腹面,第三颚足关节鳃上的板茗荷附着量最大.附着于三疣梭子蟹的角板茗荷种群年龄组成以春季最简单,秋季最为复杂;体长1～2mm的个体是春、夏、秋三个季度的优势群体,冬季的种群年龄大于其它季度.  相似文献
