Numerical Simulation of Anchorage Performance of GFRP Bolt and Concrete
Buildings, 2023 We conducted anchoring performance, stress distribution, and full-scale indoor pulling tests on glass-fiber-reinforced polymer (GFRP) bolts. The tests were conducted using finite element software while considering the multi-interface contact and BK ...

Social Bonds and Posttraumatic Stress Disorder [PDF]
Annual Review of Psychology, 2008 Retrospective and prospective studies consistently show that individuals exposed to human-generated traumatic events carry a higher risk of developing Posttraumatic Stress Disorder (PTSD) than those exposed to other kinds of events. These studies also consistently identify perceptions of social support both before and after a traumatic event as an ...
