background: to increase safety of patients and staffs in hospitals, safety standards and regulations must be considered. this study was conducted to evaluate safety conditions in hospitals affiliated to kerman university of medical sciences.   methods: this cross-sectional descriptive study was conducted in various wards and units of four hospitals affiliated to kerman university of medical sci...

This paper aims at deriving and proving some Lipschitzian type error bounds for convex conic problems in a simple way First it is shown that if the recession directions satisfy Slater s condition then a global Lipschitzian type error bound holds Alternatively if the feasible region is bounded then the ordinary Slater condition guarantees a global Lipschitzian type error bound These can be consi...

background: there can be little doubt that the construction is the most hazardous industry in the worldwide. this study was designed to modeling the factors affecting unsafe behavior from the perspective of safety supervisors. methods: the qualitative research was conducted to extract a conceptual model. a structural model was then developed based on a questionnaire survey (n=266) by two stage ...

The article is the second in a series of articles, united by single theme improving organization country’s security management system. completely based on previous “Formalization safety assessment and management” continuation it. Accordingly, uses unified approach to system, same terminology notation. It has been determined that significantly depends operating conditions control object. formati...

introduction: since hospitals give their services to a huge number of people most of whom are sick and disabled and also because they have many expensive and modern equipment and facilities, any negligence regarding the standards of safety management leads to severe damages including financial ones. this may even result in irrecoverable consequences such as their clients’ death. so, this invest...

Weak gravitational lensing provides a means of testing the long-range properties of gravity. Current measurements are consistent with standard Newtonian gravity and inconsistent with substantial modifications on Mpc scales. The data allows long range gravity to deviate from a 1/r potential only on scales where standard cosmology would use normal gravity but be dominated by dark matter. Thus, ab...
