One of the hazards faced by crews of spacecraft in space is exposure to ionizing radiation in the space environment. The main sources of these radiations are the trapped radiation in the Van Allen belts, consisting mainly of protons in the inner belt and electrons in the outer belt, the galactic cosmic ray (GCR) background, composed of all naturallyoccurring elements, and solar energetic partic...

Dark septate endophytes (DSE) occur widely in association with plants exposed to heavy metal stress. However, little is known about the response of DSE exposed to heavy metals. In this study, five DSE were isolated from the roots of Astragalus adsurgens Pall. seedlings growing on lead-zinc mine tailings in China. Based on morphological characteristics and DNA sequence analyses, the isolates wer...

To develop students' sensitivity toword medication hazards, we have introduced a behavioral approach, "Kiken-Yochi Training" (KYT) for hazard prediction training to pharmacy education. KYT was originally implemented in the field of occupational health and safety in Japan. Only recently it has been introduced in the medical arena. The process consists of four steps; identification of hazards, as...

Introduction: Uncontrolled and improper landfilling of solid waste increases the concentration of heavy metals in the soil. Therefore, this study aimed to investigate soil contamination with heavy metals in the landfill of municipal and hospital waste in Sabzevar city by compiling a map of the severity of heavy metal pollution in the soil. Materials and Methods: Concentrations of heavy metals ...

Previous studies indicate that oper­ ators of heavy construction equipment are aff icted by musculoskeletal injuries of the arms, shoulders, neck, and lower back. These injuries appear to be due to excessive periods of sitting (static posture), work intensity, whole-body vi­ bration, high resistance levers, repetitive motions, and awkward postures.2 5) Al­ though numerous studies have shown an ...

Typically, flash floods are studied ex post facto in response to a major impact event. A complement to field investigations is developing a detailed database of flash flood events, including minor events and null reports (i.e., where heavy rain occurred but there was no flash flooding), based on public survey questions conducted in near-real time. The Severe hazards analysis and verification ex...
