For any C expanding map f of the circle we study the equilibrium states for the potential ψ = − log |f ′|. We formulate a C generalization of Pesin’s Entropy Formula that holds for all the SRB measures if they exist, and for all the (necessarily existing) SRB-like measures. In the C-generic case Pesin’s Entropy Formula holds for a unique SRB measure which is not absolutely continuous with respe...

Biofilm formation is one of the major problems of recirculating cooling water systems which detriments the life of equipment, through biocorrosion or microbiologically influenced corrosion (MIC). Sulfate reducing bacteria (SRB) are considered to be the major bacterial group involved in MIC. In the present study, SRB cultures are isolated from aeration basin inlet water sample of cooling water s...

We review the basic steps leading to the construction of a Sinai-Ruelle-Bowen (SRB) measure for an innnite lattice of weakly coupled expanding circle maps, and we show that this measure has exponential decay of space-time correlations. First, using the Perron-Frobenius operator, one connects the dynamical system of coupled maps on a d-dimensional lattice to an equilibrium statistical mechanical...

BACKGROUND Arsenic (As) toxicity is primarily based on its chemical speciation. Although inorganic and methylated As species are well characterized in terms of metabolism and formation in the human body, the origin of thiolated methylarsenicals is still unclear. OBJECTIVES We sought to determine whether sulfate-reducing bacteria (SRB) from the human gut are actively involved in the thiolation...

In this article we give the detailed proof of the entropy formula for SRB-measures of coupled hyperbolic map lattices. We show that the topological pressure for the potential function of the SRB-measure is zero.

OBJECTIVE The accuracy of a population-based sex ratio at birth (SRB) in China has long been questioned. To depict a more accurate profile, the present study used data from a national surveillance system for health facility births to explore the characteristics of SRB in China. METHODS Data from China's National Maternal Near Miss Surveillance System between 2012 and 2015 were used. We restri...

Sulfate-reducing bacteria (SRB) in anoxic waters and sediments are the major producers of methylmercury in aquatic systems. Although a considerable amount of work has addressed the environmental factors that control methylmercury formation and the conditions that control bioavailability of inorganic mercury to SRB, little work has been undertaken analyzing the biochemical mechanism of methylmer...

Abstract The potential for crevice corrosion of UNS30400 stainless steel in the presence sulfate-reducing bacteria (SRB) was studied different media. Immersion studies found to occur test media supplemented with high chloride levels and SRB present gaps ~3 μm. Electrochemical measurements showed susceptibility this particular medium, demonstrated by a negative shift open circuit potential, incr...
