Conveyor belt slip on a driving drum belongs to dangerous accidents that may result in a fire and burning of the rubber belt cover and drum coating under not well described conditions. To prevent such situations temperature of the rubber coating is often monitored by optical methods. We argue that these optical measurements may not monitor the initial phase of belt slipping thoroughly enough and that they cannot predict the incoming danger. We propose to measure continuously the temperature gradient in the rubber ...

Turkey is on its way to becoming full member of European Union. Candidate countries should make some reforms on all sectors included health. The pay of the government budget for health establishments is limited. Eventhough it is central planning for healthcare it is mostly fail to be effective because of the economic reasons or practical delays. However health establishments and local administrations supports and adds it works out to deliver healthcare services for all layers of society. In this research it shows ...

The anthropic intervention is strongly felt in T\^argoviЕџte Plain. Here, man has turned most of the forest into land for agriculture, constructions, ways of communication, etc. In the past, in T\^argoviЕџte Plain, oak forests thrived because of the favorable conditions provided by the water-bearing structures situated near the surface and by the plain relief. Today, the forests of T\^argoviЕџte Plain represent nothing else but the remains of the old forest, where the wood vegetation finds however good recovery co...

This paper highlights the fact that environmental issues in the border regions are numerous. These problems in border regions are endemic to many countries. At global scale of the whole planet, the importance of transboundary pollution of the air, water, soil is far from negligible (according to reports submitted to the UN). Almost 50\% of our planet earth (excluding Antarctica) is located in international water collection tanks. In this area about 40\% of world’s population lives, stretching over more than 200 ...

As the water has a vital role in human life and economic development, its shortage can cause some economical, agricultural, industrial and environmental problems. These problems are more prominent in warm and dry regions. Therefore, in such areas the water resources management as well as the treatment and recycling of the mine drainage have the great importance. In the underground and open pit mines, we usually deal with the huge amounts of the contaminated water. In this research, by considering of the statistics...

Hydraulic impact hammers are one of the mechanical excavators that can be economically used in tunneling projects under favorable geologic conditions. However, there is relatively less published material in the literature directed to their performance prediction in terms of rock properties. In tunnel drivage projects, there is often the need for accurate means of performance prediction of related mechanical excavators. A poor prediction of machine performance can lead to very costly contractual claims. In this stu...
