Culture-independent investigations of the bacterial diversity and activity in district heating systems with and without corrosion did not make it possible to relate one group of microorganisms with the observed corrosion. Fluorescence in situ hybridization by oligonucleotide probes revealed the dominance of beta-proteobacteria, sulphate reducing prokaryotes and alpha-proteobacteria. Analysis of...

The genes encoding the desulforubidin type of dissimilatory sulfite reductase (Dsr) from the sulfate-reducing bacteria Desulfobacter vibrioformis and Desulfobulbus rhabdoformis were cloned and sequenced. Similar to the genes for dissimilatory sulfite reductase from the genera Archaeoglobus, Desulfovibrio and Desulfotomaculum the dsr genes were found to form an operon, dsrABD, where dsrA and dsr...

in this paper, rstly we have introduced to entropy of sequences of fuzzy sets and given sometheorems about it. secondly, the waves p and t which appears in electrocardiograms weretransferred to fuzzy sets, by using denition of entropy for sequences of fuzzy sets, and somenumerical values were obtained for sequences of waves p and t. thus any person can makea medical predictions for some cardiac...

This paper proposes a novel approach for predicting user satisfaction transitions during a dialogue only from the ratings given to entire dialogues, with the aim of reducing the cost of creating reference ratings for utterances/dialogue-acts that have been necessary in conventional approaches. In our approach, we first train hidden Markov models (HMMs) of dialogue-act sequences associated with ...

The diversity of microorganisms present in a sediment colonized by the phanerogam Zostera noltii has been analyzed. Microbial DNA was extracted and used for constructing two 16S rDNA clone libraries for Bacteria and Archaea. Bacterial diversity was very high in these samples, since 57 different sequences were found among the 60 clones analyzed. Eight major lineages of the Domain Bacteria were r...

Automatic assembly planning is recognized as an important tool for achieving concurrent product and process development thus reducing manufacturing costs. It plays an important role in designing and planning the assembly systems. In order to recommend a good sequence of assembly operations, the process planner needs to generate all such feasible sequences. In this paper, the representation of t...

Next-generation DNA sequencing has revolutionized the study of biology. However, the short read lengths of the dominant instruments complicate assembly of complex genomes and haplotype phasing of mixtures of similar sequences. Here we demonstrate a method to reconstruct the sequences of individual nucleic acid molecules up to 11.6 kilobases in length from short (150-bp) reads. We show that our ...

To the best of our knowledge, little information is available regarding the presence of Anaplasma species in camels in Iran. This study sought to investigate the presence of Anaplasma species by microscopy and polymerase chain reaction (PCR) assays in 100 healthy dromedaries (Camelus dromedarius) arriving for slaughter. The microscopic examination of Giemsa-stained blood films revealed that Ana...
