Exploring Pathways Toward Psychobiological Safety through Mindful Body-centered Art Making with Sheltered Homeless Women
… a trauma-informed intervention on relaxation and body awareness in sheltered homeless women, where trauma history can be a pathway to homelessness, and the experience of homelessness itself can be traumatic. The study took place at three interim housing locations along the peninsula of the greater …

The diffusion of Co⠶溩 Zrâ â Tiâ â alloy /|nS. Kumar. -- 260 St Catharines [Ont.] : Dept. of Physics, Brock University,
The diffusion of Co60 in the body centered cubic beta phase of a ZrSOTi SO alloy has been studied at 900°, 1200°, and 1440°C. The results confirm earlier unpublished data obtained by Kidson17 • The temperature dependence of the diffusion coefficient is unusual and suggests that at least two and …
