The actinobacterial diversity was investigated in the sediments of five cold springs in Wuli region on the Qinghai-Tibet Plateau using 16S rRNA gene phylogenetic analysis. The actinobacterial communities of the studied cold springs were diverse and the obtained actinobacterial operational taxonomic units were classified into 12 actinobacterial orders (e.g., Acidimicrobiales, Corynebacteriales, ...

the mikkes basin is located at the north center of morocco. it comprises three different zones which represent diversified geologies which shelter a phreatic and confined aquifer in the sais basin and a shallow aquifer in the tabular middle atlas. the springs in the sais phreatic aquifer have suffered a maximum depletion. the springs with a deep or mixed origin are known as low flow variation s...

Introduction: Radon-222 gas is a radioactive, colorless and odorless element that can cause lung cancer and stomach in humans with alpha-ray emissions. An important source of Radon-222 is the output water in springs, especially hot springs to emit ionision radiation. In this study, Rn-222 activity concentration and gamma dose rate levels in water sample of some selected hot spr...

UNLABELLED An assessment on quality and hygienic conditions of spring water was undertaken in Mongolia in 2004 with financial and technical support from the World Health Organization through AGFUND. METHODOLOGY A total of 127 springs, 99 from rural areas and 28 from Ulaanbaatar city were included in the study. The study included hygienic conditions, physical, microbiological and chemical para...

This research attempts to collect and interpret the soil salinization in the upper stream of the Tarim River on the basis of the multisource and multi-type remote sensing images and basis background data in the springs of 1999, 2002 and 2004 respectively, applying the information technologies of remote sensing (RS), global positioning system (GPS), geographic information system (GIS), and massi...

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 ...

We present the design, fabrication and test of a large-displacement electromagnetic actuator using the meander springs, exposed partially to magnetic field. We compare two prototypes including the conventional prototype F with the meander springs exposed fully to magnetic field and the present prototype P with the meander springs exposed partially to magnetic field. In the experimental study, t...
