OBJECTIVE This study examined whether the incidence of hospitalization for psychosis was reduced by a communitywide system of early identification and intervention to prevent onset of psychosis. METHODS The Portland Identification and Early Referral program (PIER) was initiated in 2001. Youths and young adults ages 12-35 were identified by professionals in a wide variety of educational, healt...

The experimental seismic testing of a 1/5-length scale model, slender bridge steel truss pier was conducted to investigate the use of a controlled rocking approach as a means of seismic protection. The controlled rocking approach allows the pier to uplift from its base, partially isolating the structure, while passive energy dissipation devices (steel yielding devices, fluid viscous dampers) ar...

Transported large wood (LW) in rivers may block at river infrastructures such as bridge piers and pose an additional flood hazard. An improved process understanding of LW accumulations is essential for a risk assessment. Therefore, we conducted field study the River Glatt Zurich (Switzerland) to analyze accumulation single logs circular pier evaluate results previous flume experiments with resp...

Mining activities can endanger the stability of hydraulic structures. Numerical modeling local scouring around hydrodynamic and circular bridge pile groups, due to action clear water conditions via non-cohesive sediment, was performed using a computational fluid dynamics (CFD) model, large eddy simulation (LES) turbulence van Rijn sedimentary model with FLOW-3D software. The groups were positio...

Base-level fall in river beds occurs due to varying natural or unnatural causes. Base-level fall causes the change in the behavior of flow at the location of drop in base-level. In such situations, most of scour occur at the foot of the slope, and slope wall retreats in the upstream direction. This phenomenon widens the wall of the river bank, thus leading to its destruction. The amount of bed ...

Identification of the nonlinear hysteretic behavior of a reinforced concrete (RC) bridge pier subjected to earthquake loads is carried out based on acceleration measurements of the earthquake motion and bridge responses. The modified Takeda model is employed to represent the hysteretic behavior of the RC pier with a small number of parameters, in which the nonlinear behavior is described by var...

Wilson The content of In the Clinic is drawn from the clinical information and education resources of the American College of Physicians (ACP), including PIER (Physicians’ Information and Education Resource) and MKSAP (Medical Knowledge and Self-Assessment Program). Annals of Internal Medicine editors develop In the Clinic from these primary sources in collaboration w...

Based on the high-pile and high-pier bridge of Qianhuang Expressway, eigenvalue buckling analysis is carried out by establishing three-dimensional finite element models three different types types, corresponding structural nonlinear loads under initial pier deviations are calculated. The calculation results show that less than elastic loads. stability column continuous better simple supported b...
