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...

Geochemical investigations have permitted the refinement of the environmental interpretation of the f-Member of the Qum formation, Central Basin, Iran, which has been established through detailed microfacies (MF) analysis. The analysis revealed that the f-Member carbonates consist of eight distinct microfacies designated by the letters A through H. On the basis of petrographic characteristi...

The stratification of the equatorial thermocline is a key variable for tropical climate dynamics, through its influence on the temperature of the water that upwells in the eastern equatorial ocean. In this study, two types of ocean models are used, an ocean general circulation model (GCM) and a 11⁄2-layer model, to investigate processes by which changes in the midlatitude winds affect the equat...

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known; the results of most studies of the subject have not been published and can only be found in grey literature (unpublished scientific works), such as course completion work and consulting reports.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...

Three new species of the lampeye genus Hylopanchax are described from the central Congo basin: H. leki, new species, H. ndeko, new species, and H. moke, new species. These differ considerably in body shape from the two previously de- scribed species, H. stictopleuron and H. silvestris, with two deep bodied and one small and slender species. A redefinition of the diagnostic characters of the gen...

We study the earthquake response of the Zevulun Valley basin, underlying northern Israel‘s largest urban area with two-dimensional viscoelastic seismic modeling of a detailed geological section. We found that amplification of the horizontal vibrations, the ratio of basin to no-basin response spectra, correlates with basin depth. In the deepest portion of the basin (Qishon graben) long periods (...

The variation of river hydrologic process can reflect the impact not only natural factors, but also human activities. purpose this study is to reveal change in regime Yellow River and its response ecological protection. Based on daily water sediment observation data representative gauging stations River, we analyzed annual monthly runoff suspended load (SSL), as well mean runoff, transport rate...

the aim of this paper is to evaluate the effect of tectonic on the volume of alluvial fans around danehkhoshk anticline. to achieve the purpose of this study, at first, borders, sweep angle(s) and radius(r) of alluvial fans were obtained based on quick bird satellite image and then difference in the altitude between the apex and toe of alluvial fans (h) were calculated based on topographic map ...
