background: fire and explosion hazards are extremely important in processing units. this study was performed to identify the risk centers, the potential damage caused by fire and explosion, and the days of production cessation in the processing company. materials and methods: the present qualitative case study was conducted using dow’s index in 2015. the fire and explosion hazard index and leve...

The objective of this study was to evaluate non-genetic factors affecting longevity and survival of Guilan sheep from birth to yearling. Longevity and survival records of 41037 lambs born from 496 rams and 10256 ewes of Guilan sheep were analyzed using linear and Weibull models. Results indicated that the overall mean of longevity was 1260.84 days. The fixed effects of flock, dam age, sex, year...

there are enormous quantities of unknown composition of hazardous wastes in tehran without any control, safe disposal and treatment. this study was done to identify hazardous wastes and to control this wastes by establishing a treatment, storage and disposal facility. according to available statistics there are 4461 different industries in tehran, out of which sample were chosen each having ove...

This Study aims to determine the effect of application Good Manucturing Practices (GMP) and preparation Sanitation Standard Operational Procedure (SSOP) on processing frozen squid, Hazard Analysis Critical Control Point (HACCP) system as a moderating variable. The results research that love been carried out show influence implementation Manufacturing (GMP), Sanitasi squid. However, is not able ...

Operating robotic space missions via time-based command sequences has become a limiting factor in the exploration, defense, and commercial sectors. Command sequencing was originally designed for comparatively simple and predictable missions, with safe-mode responses for most faults. This approach has been increasingly strained to accommodate today’s more complex missions, which require advanced...

Several requirements analysis techniques widely used in safety-critical systems are being adapted to support the analysis of secure systems. Perhaps the most relevant system safety technique for Intrusion Detection Systems is hazard analysis. Hazard analysis identi es and analyzes hazards (states that can lead to an accident) in terms of their severity of e ects and likelihood of occurrence. As...

Increasingly, user generated content (UGC) in social media postings and their associated metadata such as time and location stamps are being used to provide useful operational information during natural hazard events such as hurricanes, storms and floods. The main advantage of these new sources of data are twofold. First, in a purely additive sense, they can provide much denser geographical cov...
