The present work aims at approximating the reduction of sulphate to sulphide caused by sulphate-reducing bacteria (SRB) inside Canadian deep geological repository in order calculate expected lifetime used nuclear fuel containers (UFCs). Previous studies have assumed a conservative constant concentration host rock interface. novelty this study resides use first-order kinetics explicitly account ...

We agree with the referee that this remains puzzling, however it is not our intention to determine why SRB fix nitrogen, but merely to provide more evidence that N2 fixation, possibly by SRB, exists in benthic systems. We have added in a citation (Knapp, 2012) that goes into great detail about the possible reasons for this occurrence and summarizes the many studies that have also documented ben...

We show that existence of positive Lyapounov exponents and/or SRB measures are undecidable (in the algorithmic sense) properties within some parametrized families of interesting dynamical systems: quadratic family and Hénon maps. Because the existence of positive exponents (or SRB measures) is, in a natural way, a manifestation of “chaos”, these results may be understood as saying that the chao...

We give geometric conditions that are necessary and sufficient for the existence of Sinai–Ruelle–Bowen (SRB) measures $$C^{1+\alpha }$$ surface diffeomorphisms, thus proving a version Viana conjecture. As part our argument we an original method constructing first return Young towers, every hyperbolic measure, in particular SRB can be lifted to such tower. This relies on new general result branc...

Frequent flooding can greatly jeopardize local people’s lives, properties, agriculture, economy, etc. The Swat River Basin (SRB), in the eastern Hindukush region of Pakistan, is a major flood-prone basin with long history devastating floods and substantial socioeconomic physical damages. Here we produced flood susceptibility map SRB, using frequency ratio (FR) bivariate statistical model. A dat...

At present, a variety of global remote sensing surface downwelling longwave radiation (SDL) products are used for atmospheric science research; however, there few studies on the quantitative evaluation differences among different SDL products. In order to evaluate quantitatively, we have selected three commonly products—Clouds and Earth’s Radiant Energy System-Synoptic Radiative Fluxes Clouds (...

Here, we describe a three-step nested-PCR-denaturing gradient gel electrophoresis (DGGE) strategy to detect sulfate-reducing bacteria (SRB) in complex microbial communities from industrial bioreactors. In the first step, the nearly complete 16S rRNA gene was amplified using bacterial primers. Subsequently, this product was used as a template in a second PCR with group-specific SRB primers. A th...
