Nursing hospitals have a high probability of casualties during fire disaster because they many patients with impaired mobility. In this study, and egress simulations were conducted to evaluate the safety typical nursing hospital. The available safe time (ASET) prototype hospital was calculated using Fire Dynamics Simulator, required (RSET) estimated by Pathfinder, reflecting characteristics occ...

Abstract Introduction Shiftworkers experience altered sleeping patterns and eating habits compared to dayworkers. This leads long-term negative health outcomes. While characteristics of shiftwork, such as work hours food availability, impact habits, the on behaviour shiftworkers is unknown. The aim this study was explore how sleep through analysis Facebook comments. Methods search function used...

A retrospective cohort study was carried out on workers in a fertiliser plant to assess the risk of stomach and lung cancer. The cohort comprised 603 subjects and their death rates were compared with those of the general male population in Iceland. The study period was 1954 to 1985. The results do not provide evidence of an excess of deaths from stomach or lung cancer. Total mortality was lower...

Following the implementation of the European Working Time Directive Regulations, almost all junior doctors in the UK now work full night-shifts. An RCP 50-member working group was established to develop a practical guide to help junior doctors prepare, survive and recover from working night shifts. The guide, set out in this paper, examines the evidence concerning the hazards of shiftwork, and ...

The ability of melatonin to shift biological rhythms is well known. As a result, melatonin has been used in the treatment of various circadian rhythm sleep disorders, such as advanced and delayed sleep phase disorders, jet lag and shiftwork disorder. The current evidence for melatonin being efficacious in the treatment of primary insomnia is less compelling. The development of agents that are s...

this study was conducted to determine drought tolerance genotypes with superiority in different stressed environments. to screening quantitative indices of drought tolerance, genotypes of safflower (carthamus tinctorius l.) were tested in a complete randomized block design with three replications under two different water regimes (irrigated and rainfed). significant positive correlation was fou...

Human fatigue, caused by sleep loss, extended wakefulness, and/or circadian misalignment, is a major cause of workplace errors, incidents and accidents. In some industries, employees are required to undertake fitness for duty testing at the start of a shift to identify instances where their fatigue risk is elevated, so that minimisation and/or mitigation strategies can be implemented. Postural ...
