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known; the results of most studies of the subject have not been published and can only be found in grey literature (unpublished scientific works), such as course completion work and consulting reports.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

Geophysical surveys in the eastern slope of Gela Basin (Strait Sicily, central Mediterranean) contributed to identification several episodes sediment mass transport, recorded by scars and deposits various dimensions within Pleistocene succession. In addition a huge failure called Slide with volume exceeding 600 km 3 , most studied events show volumes estimated between 0.5 1.5 which is common ma...

Geologi suatu daerah sebagai model dapat mengalami perubahan secara konstruktif (refining), sejalan dengan munculnya gagasan-gagasan baru dalam sedimentasi, stratigrafi, tektonik dan evolusi cekungan, serta vulkanisme, didukung oleh berbagai jenis data yang lebih banyak akurat. Suatu kolase elemen-elemen dasar disusun lokal dihubungkan satu lain menurut kaidah dianut akan membentuk pengertian b...

putative calcium channel specific to sperm tails may be the best target yet for a male contraceptive. The protein, dubbed CatSper, was discovered in a homology search by David Clapham and colleagues of Harvard Medical School, Boston, MA. CatSper looks like a calcium channel, although Clapham could not detect a calcium current in transfected cells, probably because another component of the chann...
