Mycobacterium parascrofulaceum was found in Norris Geyser Basin, Yellowstone National Park, in a system composed of two acidic (pH 3.0) springs with temperatures between 56 degrees C at the source and 40 degrees C at the confluence of both springs. Growth and survival assays at 56 degrees C for 60 days were performed, confirming the origin of the strain.

This article forms pan of an ongoing study of the coal and coalbed methane resource potential of northwestern British Columbia. Other areas under study include the Bower basin coalfield, Telkwa coalfield and Tertiary coalfields of the Bulkley Valley. Tertiary sediments survive in many major watersheds in British Columbia. The sediments are generally not well consolidated, poorly exposed and the...

The plankton fauna of the state of Piauí, Northeastern Brazil, especially in the Parnaíba basin, is still poorly known; the results of most studies of the subject have not been published and can only be found in grey literature (unpublished scientific works), such as course completion work and consulting reports. Thus, this paper presents data from samples taken recently from different water bo...

The Dom João de Castro seamount in the Hirondelle Basin (Azores) is a central volcano on ultraslow diverging Terceira Rift axis. combination of structural and geochemical data provides insights into evolution volcanoes oceanic rift systems above Azores melting anomaly. orientation fault scarps volcanic structures at D. adjacent fissure zone indicate that regional SW-NE extending stress field do...

The current practice of hydraulic engineering construction applies four methods for damping extra energy excess water discharge: throwing out the stream into tailwater; using twisting in passageway, a water-well, and on multistage drop; vertical shaft. cheapest method is by jet downstream reservoir. main disadvantages limiting use this include need appropriate topographic conditions tailrace ba...

supersonic separators have found extensive applications in dehumidification of natural gases since 2003. unlike previous studies, which have investigated the inlet conditions and nozzle geometry of supersonic separators for pure fluids, the present study employed a combination of momentum, heat, and mass transfer equations along with virial equation of state (eos) to inspect the effect of inlet...
