The effect of modifiers on the stability of a vinyl acetate/ethylene copolymer dispersion     

Jane L. Down 《文物保护研究》2016,61(1):26-45

This paper examines the effect of modifiers on the stability of a vinyl acetate/ethylene copolymer dispersion adhesive upon aging. Eighteen common modifiers were added to a well-characterized vinyl acetate/ethylene copolymer dispersion (Dur-O-Set^® E-150) in known concentrations and dry-film samples were subjected to 16–17 years of dark aging and seven to eight years of light aging. Yellowing, pH, gloss, swelling, cohesive strength, and flexibility were monitored for changes upon aging. Generally, the neat Dur-O-Set^® E-150 (no additives) was found to become acidic on aging, but was fairly resistant to yellowing. It also swelled substantially in toluene, was of high gloss, medium strength, and flexible, and remained so on aging. No modifier was found to improve these properties. Various solvents, wetting agents, and thickeners did not alter the properties by much, while plasticizers, freeze-thaw stabilizer, glycerin, and certain fillers had a more negative effect.  相似文献

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   

Age and sex influences on running mechanics and coordination variability     

Katherine A. Boyer  Julia Freedman Silvernail  Joseph Hamill 《Journal of sports sciences》2017,35(22):2225-2231

The purpose of this study was to examine the impact of age on running mechanics separately for male and female runners and to quantify sex differences in running mechanics and coordination variability for older runners. Kinematics and kinetics were captured for 20 younger (10 male) and 20 older (10 male) adults running overground at 3.5 m · s^?1. A modified vector coding technique was used to calculate segment coordination variability. Lower extremity joint angles, moments and segment coordination variability were compared between age and sex groups. Significant sex–age interaction effects were found for heel-strike hip flexion and ankle in/eversion angles and peak ankle dorsiflexion angle. In older adults, mid-stance knee flexion angle, ankle inversion and abduction moments and hip abduction and external rotation moments differed by sex. Older compared with younger females had reduced coordination variability in the thigh–shank transverse plane couple but greater coordination variability for the shank rotation–foot eversion couple in early stance. These results suggest there may be a non-equivalent aging process in the movement mechanics for males and females. The age and sex differences in running mechanics and coordination variability highlight the need for sex-based analyses for future studies examining injury risk with age.  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
