fBackground: Due to increasing of human knowledge conserning control, treatment, prevention and eradication of fungal diseases, people with fungal diseases such as dermatophytosis in humans and animals have shown that the disease is still one of the most important health issues in Iran and the world. Pollution of hot springs pools to dermatophyte and saprophytic fungi can increase the risk of n...
Springs are the important water resources, which thier study is necessary in terms of their management and exploitation. In northern Iran, the karst springs locate in the central Alborz highlands and alluvial springs on the Caspian southern coasts.The Karst and alluvial springs discharge is variable because of different conditions in terms of aquifer, topography and precipitation .This study ha...
introduction the aim of this study was to compare the characteristics of deflection load of three kinds of nickel titanium closed coil springs. methods and materials this research was an experimental study. research sample contains three kinds of niti closed coiled springs (heavy, medium, light) from gac, 3m, and rmo factories. 10 springs with 9 mm length for each group (totally 90 springs) wer...

1-Introduction Travertines are limestones that form where hot groundwaters rich in calcium and bicarbonate emerge at springs. Travertines cover a large area southwest of Azarshahr (East Azarbaijan province), in some parts of which active springs are currently settling travertine. One of the main questions about travertine springs is their origin, as well as the secondary processes that have ch...
In this research, due to the abundance of tectonic and karstic structures in the Prav Bisotun region, the relation between fault building and karstic springs was evaluated. To do this, we first prepare information layers including the location of the springs, the location of the closed holes, faults, the slope and the elevation floor layer, and then the graph of the grains of the faults is draw...
One hundred and nineteen karst springs, all with electrical conductivity of less than 500 gmhosfcm, discharging two carbonatic aquifers in Zagrosides of Iran are chosen and studied. The results indicate that the lithology of each unit is well reflected in the chemistry of the springs and the overall mineralogical composition of the aquifer can successfully be reconstructed from the hydroche...
Corrosion and scaling in drinking water sources can lead to economic and health damages. These processes produce by-products in distribution systems, reduce chemical water quality, and are the cause of health issues among consumers. The aim of this study was to evaluate the corrosion and scaling potential of water supply sources of Marivan villages, Iran. In total, 106 water samples were collec...
springs are the mechanical parts which have many application in industries. static and dynamic forces cause relaxation in these parts so that they lose some of their free length and reaction force. springs constant are very important in airplane and vailway industry since constant and variable forces are applied to them in period time, therefore it is necessary to avoid decreasing in spring co...
Background: Free-living amoebae, which are called as amphizoic amoebae, could live in various environmental sources such as water, soil, dust and also human and animal tissues. According to possible contamination of hot springs to free living amoebae and developing related disease such as keratitis and encephalitis in people at risk and the lack of knowledge regarding their distribution in hot ...
