Abstract

The hazards that have cross-border consequences and represent a great problem for communities, become an obstacle to sustainable development and lead to disasters when combined with vulnerability and insufficient capacity to mitigate the risk. A short overview of research already implemented and in progress presents us a shift in systematic evaluation of the hazards and disasters at local and areal level. Hazard assessment of natural disasters (earthquakes, landslides and floods) on these scales can give results which can be directly used to take right decisions regarding preventive measures and plan effective actions of post-event management. The issue is widely recognized in the european union (eu) implicitly also in the black sea area, and a lot of efforts have already been made to mitigate the effects of disasters, obviously through the formation of numerous eu institution, established organizations and funded projects. The key elements for an effective mitigation of natural disasters are hazard identification and risk assessment, which must be based on scientifically grounded methodologies, reliable and accurate data. Successful resolution of the issues mentioned above will provide the ability to systematically assess natural disasters on regional and local scales, even in cross-border areas, by providing comparable hazard maps that will support the decision-making process in relation to mitigation measures required. The effective way of action against them is by providing applied research and technology transfer between partners in different countries by solving the problems such as lack of reliable information and lack of 'common ground' in the methodologies used to assess natural hazards and adopted procedures for mitigation.

Abstract

Atmosphere pollution is a complex and worldwide process carried out for a long period of time. Greenhouse effect, global warming and acid rain are only some examples generated by atmospheric pollution. Experts discovered a strong motivation on finding solutions for reducing pollutant emissions caused by atmospheric pollution. Transport activities and fossil fuels combustion are the main concern on environmental pollution, more than that, they are used in industrial processes, being the main cause of environmental pollution.

We have to understand that global pollution is causing the main effect on economic and social challenges of each country, a fact that will be hard to change in the future, and every small step will help for a better and healthy environment. Sebes and Zlanta city, from Alba regions, were the areas that draw our attention for studying the level of atmospheric pollution for a period of 5 years. We made periodic determinations on emission level for SO2, CO, CO2, NOx and writing down periodic reports. The measurements were made in industrial areas for Zlatna and Sebes city and in urban areas in Alba-Iulia city. Traffic environment was the main issue discovered after this research. The concerning was on industrial pollution for the cities of Sebes and Zlatna. The final part is offering solutions on reducing gaseous emissions in particular for economic operators and for the industries as well. This research is particularly aimed at emissions reduction like SO2, CO, CO2 and also for volatile organic compounds. Directive 2008/50/CE concerning ambient air quality were the main sources where we started on our research targeting on reducing atmospheric pollution.

Abstract

The use of magnesium alloys in the automotive industry increased in the last decade because of their low weight and relative good mechanical properties. However, the variable loading conditions require a good fatigue behavior. This paper summaries the fatigue properties of magnesium alloys and presents new fatigue curve results for die cast AM50 magnesium alloy.
