mahallat hot springs located in the northeast of mahallat, in central iran. there are 6 main hot springs namely shafa, abejoush, donbeh, soleimanie, hakim and soda. in this research, geology, physico-chemical characteristics and petrography of basement rocks of these hot springs have been investigated. the results show that hot springs have an average temperature of 45°c and acidic to neutral p...

conclusions the current report isolates, characterizes, and demonstrates the novel heat-adapted amylase-producing bacteria ss1, ss2 and ss3 from taptapani hot spring, indicating its potentiality and stability under acidic conditions. materials and methods bacterial strains were isolated by dilution plating method from the water samples collected from taptapani hot spring, odisha and screened fo...

Tourism in hot spring areas has been popular in Taiwan recently. However, hot spring resources are limited and scarce, so it is important to use hot spring resources effectively and appropriately, and study hot spring industrial symbiosis and industry chain. Therefore, the study constructs a hot spring industrial park model through ecological viewpoint. PDCA cycle is adopted to install the oper...

introduction natural and artificial radionuclides are the main sources of human radiation exposure. these radionuclides, which are present in the environment, can be dissolved into water. evidence suggests that radionuclides being entered the human body through drinking or hot spring water can be harmful for human health. materials and methods in this study,10 samples were collected from ground...

Hot spring or hot spa bathing (Onsen) is a traditional therapy for the treatment of certain ailments. There is a common belief that hot spring bathing has therapeutic effects for wound healing, yet the underlying molecular mechanisms remain unclear. To examine this hypothesis, we investigated the effects of Nagano hot spring water (rich in carbonate ion, 42°C) on the healing process of the skin...

introduction:  all of  the  people worldwide  are exposed  to  low levels  of  radiation. cancer induction  and  genetic disorders are among the hazards of low level exposure. in some cases, radiation close to hot springs is  higher than normal areas due to a high concentration and the decay products of ra-226. given the use of hot  springs by the general public  because  of their therapeutic p...

Hot springs have been investigated since the XIX century, but isolation and examination of their thermophilic microbial inhabitants did not start until the 1950s. Many thermophilic microorganisms and their viruses have since been discovered, although the real complexity of thermal communities was envisaged when research based on PCR amplification of the 16S rRNA genes arose. Thereafter, the pos...

Gaynarje spring is one of the hottest springs in the world and is located around Meshginshahr in northwestern Iran. Because of the water with a temperature of 82 ºC, it is not appropriate to use this mineral water for swimming and bathing. In this study, in addition to lowering the water temperature to the appropriate swimming temperature (29 ºC), the hot water is used for power and natural gas...

background: free-living amoebae (fla) are a group of ubiquitous protozoan, which are distrib­uted in the natural and artificial environment sources. the main aim of the current study was to identify the presence of fla in the recreational hot springs of sarein in ardebil province of iran. methods: seven recreational hot springs were selected in sarein city and 28 water samples (four from each h...
