simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Partitioning and translation of mRNAs encoding soluble proteins on membrane-bound ribosomes.
In eukaryotic cells, it is generally accepted that protein synthesis is compartmentalized; soluble proteins are synthesized on free ribosomes, whereas secretory and membrane proteins are synthesized on endoplasmic reticulum (ER)-bound ribosomes. The partitioning of mRNAs that accompanies such compartmentalization arises early in protein synthesis, when ribosomes engaged in the translation of mR...
متن کاملMembrane Proteins Are Dramatically Less Conserved than Water-Soluble Proteins across the Tree of Life
Membrane proteins are crucial in transport, signaling, bioenergetics, catalysis, and as drug targets. Here, we show that membrane proteins have dramatically fewer detectable orthologs than water-soluble proteins, less than half in most species analyzed. This sparse distribution could reflect rapid divergence or gene loss. We find that both mechanisms operate. First, membrane proteins evolve fas...
متن کاملIdentification of genes encoding the folate- and thiamine-binding membrane proteins in Firmicutes.
Genes encoding high-affinity folate- and thiamine-binding proteins (FolT, ThiT) were identified in the Lactobacillus casei genome, expressed in Lactococcus lactis, and functionally characterized. Similar genes occur in many Firmicutes, sometimes next to folate or thiamine salvage genes. Most thiT genes are preceded by a thiamine riboswitch.
متن کاملGenetic Polymorphisms within The Intronless ACTL7A and ACTL7B Genes Encoding Spermatogenesis-Specific Actin-Like Proteins in Japanese Males
Actins play essential roles in cellular morphogenesis. In mice, the t-actin 1 and 2 genes, which encode actin-like proteins, are specifically expressed in haploid germ cells. Both T-ACTIN 1/ACTLB and T-ACTIN 2/ACTL7A have also been cloned as orthologous genes in humans; they are present on chromosome 9q31.3 as intronless genes. Defects of germ cell-specific genes can introduce infertility witho...
