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...

In general, water cannot be economically pumped through raceways; it must flow through them by gravity. The need for large volumes of good quality water is the principal reason raceways have been limited to sites with large springs. Most raceway culture in the U.S. is with coldwater species such as trout and is based around locations with high volume, cold springs, or creeks. A few raceway syst...

Despite the close attention springs have received from a hydrologic perspective and as biodiversity hotspots, multiple dimensions of spring meiofaunal assemblage diversity are still poorly investigated. Knowledge beta patterns drivers can inform improve management decisions on conservation. Here, we analyzed copepod assemblages in karst Central Italy by focusing on: 1) relative contributions tu...

Malaysia has a great number of hot springs, especially along the flank of the Banjaran Titiwangsa mountain range. Biological studies of the Malaysian hot springs are rare because of the lack of comprehensive information on their microbial communities. In this study, we report a cultivation-independent census to describe microbial communities in six hot springs. The Ulu Slim (US), Sungai Klah (S...
