1. Effect of Lime Addition to CaSO 4 Oxygen Carrier in Chemical Looping Combustion
Abstract Chemical-looping combustion (CLC), which has the characteristic of greenhouse gas CO2 inherent separation, is a novel combustion technology. In this study, CLC experiments of methane using CaSO4 oxygen carrier with lime addition were carried out in a batched fluidized bed reactor, where the sample was exposed to alternate oxidizing and reducing cond

2. Avaliação de ensaios simulativos de corrosão e biocorrosão em sistemas estático e dinâmico de revestimentos aplicados em aço carbono
The global cost caused by the corrosion represents a high economical loss. Several are the attempts of to retard the corrosion process, standing out the use of metallic and organic coatings. In this work, the anticorrosive properties coatings applied on carbon steel used in the industrial areas as alternatives of anticorrosive protection were investigated, b

3. Oligomerization of the transcription termination factor TTF-I: implications for the structural organization of ribosomal transcription units.
Mammalian ribosomal genes are flanked at their 5'and 3'ends by terminator sequences which are recognized by the transcription termination factor TTF-I. The occurrence of the same binding site upstream and downstream of the gene raises the possibility that TTF-I can interact with both sequences simultaneously and thus brings the terminator in the vicinity of

4. Expression of yeast 5S RNA is independent of the rDNA enhancer region.
In the yeast Saccharomyces cerevisiae, each of the tandemly repeated ribosomal RNA genes carries a 5S gene within the 'non-transcribed' spacer region. These 5S RNA genes lie between the rDNA enhancer and the promoter of rRNA transcription. Since there is roughly equimolar synthesis of 5S RNA and the 35S rRNA precursor transcript we asked whether the enhancer
