in this study multivariate statistical analysis are used to characterize relationships between hydrochemical properties ofthermal and non-thermal springs. four factors for thermal waters and two for non-thermal springs were extracted basedon factor analysis. in thermal springs, the first factor showed high loading on ca, mg, na and k and this factor wasinterpreted as leaching of cations in the ...

Introduction: Hydrochemical properties of waters used in balneotherapy are very important, as they play a key role in success or failure of this kind of treatment. There are 30 mineral and hot spas in Hormozgan Province, Southern Iran, which are traditionally used for treating diseases. In this study, hydrochemical properties of Fotoyeh and Sanguyeh Springs, in western Hormozgan Province, are d...

One of the largest karst springs in North China, the Jinci Springs, dried up and has remained dry since 1994. We develop a correlation analysis with time-lag and a regression analysis with time-lag to study the relation between spring flow and precipitation. This allows us to obtain a better understanding of karst hydrological processes by differentiating the contribution of variation in precip...

BACKGROUND Geothermal waters could be suitable niches for thermophilic free living amoebae including Naegleria and Hartmannella. Ardebil Province, northwest Iran is popular for having many hot springs for recreational and health purposes activity. The present research is the first molecular based investigation regarding the presence of Naegleria and Hartmannella in the hot springs of Ardebil Pr...

The growth range in nature of bacteria belonging to the genus Thermus was investigated by sampling 55 different hot springs in Iceland. The springs ranged in temperature from 32 to 99 degrees C, and in pH from 2.1 to 10.1. Viable counts of Thermus spp. ranging from 10 to 10 CFU/100 ml of spring water were found in 27 of the springs sampled. The temperature range for these bacteria was found to ...

This study was conducted to address the distribution of Acanthamoeba genotypes in therapeutic hot springs in Iran. Sixty water and sediment samples were collected from bicarbonate, sulphur, and sodium chloride thermal springs in the northwest. All hot springs examined are used mainly for health purposes in Iran. Acanthamoeba were identified by both morphology and PCR (polymerase chain reaction)...
