The Personnel Protection System (PPS) at the Stanford Synchrotron Radiation Laboratory is summarized and reviewed from the radiation safety point of view. The PPS, which is designed to protect people from radiation exposure to beam operation, consists of the Access Control System (ACS) and the Beam Containment System (BCS). The ACS prevents people from being exposed to the very high radiation l...

The conditions of high hydraulic risk are mainly due to the interference between river network and bridges, their relative access ramps road embankments located in floodplain. Actually, bridges not always structurally adequate withstand severe flood waves. In restoration works, there is an objective difficulty implementing structural safety because historical, artistic economic issues. Thus, mi...

in this paper, we develop a ramsey-type endogenous growth model in which government spending on property rights protection is a major determinant of economic growth. this model includes equations for welfare, private and public sectors production. we introduce the legal efficiency into private production function, and x-inefficiency parameter into public production function. also, we consider t...

A significant amount of research has examined what motivates people living in fire-prone areas to mitigate their wildfire risk (i.e. engage activities that reduce vulnerability and the effects a on an individual’s property). However, drawing overarching conclusions from this is difficult because myriad ways researchers have measured analysed mitigation. Although recommendations exist for measur...
