For any software system upon which lives depend, the most important question one can ask about it is, ‘How do we know the system is safe?’ Despite the critical importance of this question, no widely accepted, generally applicable answer exists. Instead, debate continues to rage over the question, with theorists and practitioners quarrelling with each other and amongst themselves. This paper sug...

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...

in order to ensure the safety of parenterals, international pharmacopoeias and national standards have set up stringent guidelines and standards. particulate con- tamination is a potential health risk caused by intravenous injection of particles large enough to potentially clog the small arteries. particles could be produced through manufacturing and packaging or even dispensing of the pharmace...

INTRODUCTION Punching glass can cause severe and debilitating injuries. The literature is scant in regards to the injury patterns, optimal management, and preventative strategies. We have reviewed our experience of these injuries at a regional Australian hospital. METHODS A retrospective chart review of all patients who had punched glass and presented to Cairns Base Hospital between January 2...

Glass fabric reinforced thermoplastic (GFRT) constitutes a class of composite materials that are especially suited for automobile construction due to their combination low weight, ease production and mechanical properties. However, in the manufacturing process, during forming prefabricated laminates, defects glass as well polymer matrix can occur, which may compromise safety or lifetime compone...

Laminated glass is ever more frequently used nowadays. This applies to the automobile industry and construction industry. In cars, this refers mostly front rear windows, whereas in construction, technical safety for railings window glass. The task of type provide sufficient resistance against mechanical impact unpleasant weather conditions. At same time, if it damaged, has break into smallest p...

objective: the aim of this study was to investigate the translucency of resin-modified glass-ionomer cements (rmgic) and polyacid-modified composite resin (pcmr) over a period of one year. materials and methods: the study was done on three rmgic (fuji ii lc, photac-fil aplicap and vitremer) and one pcmr (dyract). a conventional gic (fuji cap ii) and two composite resins (tetric and z 100) were ...

background: the clinical success of sandwich technique depends on the strength of resin-modified glass ionomer cement (rmgic) bonding to both dentin and resin composite. therefore, the shear bond strength (sbs) of resin composite bonded to rmgic utilizing different resin adhesives versus a gic-based adhesive was compared. materials and methods: in this in vitro study, 84 holes (5×2 mm) were pre...
