We consider open sets of maps in a manifold M exhibiting non-uniform expanding behaviour in some domain S ⊂ M . Assuming that there is a forward invariant region containing S where each map has a unique SRB measure, we prove that under general uniformity conditions, the SRB measure varies continuously in the L1-norm with the map. As a main application we show that the open class of maps introdu...
The influence of sulfate-reducing bacteria (SRB) on the corrosion behaviors X80 pipeline steel was investigated in a soil environment by electrochemical techniques and surface analysis. It found that SRB grew well acidic further attached to coupon surface, resulting microbiologically influenced (MIC) steel. process significantly affected biofilm surface. Steel inhibited highly bioactive at earl...
The community structure of sulfate-reducing bacteria (SRB) of a marine Arctic sediment (Smeerenburgfjorden, Svalbard) was characterized by both fluorescence in situ hybridization (FISH) and rRNA slot blot hybridization by using group- and genus-specific 16S rRNA-targeted oligonucleotide probes. The SRB community was dominated by members of the Desulfosarcina-Desulfococcus group. This group acco...
Students with School Refusal Behaviour (SRB) are a diverse group, often associated negative academic repercussions (e.g., low performance, learning difficulties or demotivation). The aims of this research were: 1) to identify school refusal behaviour profiles based on and high scores the four functional conditions assessed by Assessment Scale-Revised (SRAS-R) 2) examine relationship between SRB...
Childhood abuse is relatively prevalent among women and is an important risk factor for both criminal behavior and suicide-related behavior (SRB). Based on a sample of 266 female offenders, we address one theoretical and one practical issue. First, from a theoretical perspective, we assess whether internalizing (depression and anxiety) and externalizing (substance abuse and antisocial behavior)...
Sulfate-reducing bacteria (SRB) are traditionally considered as strict anaerobic microorganisms. But there are a lot of data up to date about survival and metabolic activity of SRB in biotopes periodically exposed to oxygen. The main factor of O2 toxicity is the action of products of oxygen incomplete reduction, so called the reactive oxygen species (superoxide anion radical, hydrogen peroxide ...
Sulfate-reducing bacteria (SRB) and sulfur-oxidizing bacteria (SOB) have been studied extensively in marine sediments because of their vital roles in both sulfur and carbon cycles, but the available information regarding the highly diverse SRB and SOB communities is not comprehensive. High-throughput sequencing of functional gene amplicons provides tremendous insight into the structure and func...
Microbial biofilm and corrosion in cooling systems are the most common problems that damage expensive equipment, cause loss of production, and increase maintenance costs. Sulfate reducing bacteria were considered the major bacterial group involved in microbiologically influenced corrosion (MIC). We investigated the survival and enumeration of biofilm-associated SRB on coupons of galvanized stee...
The evaluation of individual cognitive change has relied heavily upon the raw change score, defined simply as the difference between follow-up and baseline scores. However, raw changes scores are susceptible to the confounding effects of both regression-to-the-mean and practice effect. The clinical relevance of raw change scores for the older adult is also obscured by normal, age-related cognit...
