Assessment of the health impacts of recreational water quality is a useful tool in developing appropriate policies. Risk assessment approaches are increasingly being used as a scientific rationale for risk management. This chapter describes the various methods used for identification and quantification of hazards in recreational water risk assessment. It also looks at how different factors infl...

Cities in the developing world are facing increased risk of disasters and the potential of economic and human losses from natural hazards is being exacerbated by the rate of unplanned urban expansion and influenced by the quality of urban management. Risk assessment has come to be regarded by many analysts as a critical part of the development of sustainable communities. The risk assessment fun...

Seismic hazard analysis of vulnerable countries on the Alpine-Himalayan belt has great importance to be considered. Recently, Iran as one of the countries located on the stated belt has experienced a few number of severe earthquakes. A wellestablished index of how earthquakes affect buildings is by assessing probable Peak Ground Acceleration (PGA) which can be estimated by past events. For this...

risk assessment and management techniques are used in industrial activities to reduce accidents by applying preventive and protective methods. in this article a preventive approach called hazard and operability study (hazop) was used. the application of hazop, a process hazard identification and control method, has been demonstrated in the fatty acid unit of golnar oil company, northwest of teh...

A probabilistic seismic hazard assessment in terms of Arias intensity is presented for the city of Tehran. Tehran is the capital and the most populated city of Iran. From economical, political and social points of view, Tehran is the most significant city of Iran. Many destructive earthquakes happened in Iran in the last centuries. Historical references indicate that the old city of Rey and the...

Exploration of planets has significant chances of discoveries e.g. discovery of new substances, as well as finding keys to the origin of our planet. However, some terrains are poorly explored, especially the underground ones. Thus, we have developed underground explorers that use peristaltic crawling of an earthworm for a propulsion part and an earth auger (EA) for an excavation. In this paper,...
