A rapid and precise standard-bracketing method has been developed for measuring femtogram quantity rare earth element (REE) levels in natural carbonate samples by inductively coupled plasma sector field mass spectrometry that does not require chemical separation steps. A desolvation nebulization system was used to effectively reduce polyatomic interference and enhance sensitivity. REE/Ca ratios...

Geothermal resource potential at Brady’s Hot Springs is well expressed by a series of active vents and fumaroles, readily seen at the surface. This potential is currently exploited for both power production and at-source use (garlic drying). At Brady’s Hot Springs the location of the Brady’s Fault is strongly expressed by a linear trend of fumaroles that extend a distance of approximately 4 km....

High hydrostatic pressure processing (HPP) is currently being used as a treatment for certain foods to control the presence of food-borne pathogens, such as Listeria monocytogenes. Genomic microarray analysis was performed to determine the effects of HPP on L. monocytogenes in order to understand how it responds to mechanical stress injury. Reverse transcriptase PCR analysis of tufA and rpoC in...

Chlamydia spp. are obligate intracellular bacterial pathogens that alternate between two metabolically and morphologically distinct developmental forms, and differentiation depends on transcriptional regulation. Genome sequencing of Chlamydia trachomatis revealed an ORF, CT630 (chxR), whose amino acid sequence contains a winged helix-turn-helix motif similar to the DNA-binding domain of respons...

A database consisting of 163 data on the uranium content and 234U/238U initial activity ratio 15 Italian travertine calcareous tufa sites was created using from relevant literature. Using a graphical method, were interpreted considering U geochemistry in natural environments as well geological, hydrogeological hydrogeochemical settings each site. The appear to be affected by different factors, ...
