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. ...
Heat capacity changes associated with DNA duplex formation: salt- and sequence-dependent effects.
Duplexes are the most fundamental elements of nucleic acid folding. Although it has become increasingly clear that duplex formation can be associated with a significant change in heat capacity (deltaC(p)), this parameter is typically overlooked in thermodynamic studies of nucleic acid folding. Analogy to protein folding suggests that base stacking events coupled to duplex formation should give ...
متن کاملReduced-stringency DNA reassociation: sequence specific duplex formation.
Reduced-stringency DNA reassociation conditions allow low stability duplexes to be detected in prokaryotic, plant, fish, avian, mammalian, and primate genomes. Highly diverged families of sequences can be detected in avian, mouse, and human unique sequence dNAs. Such a family has been described among twelve species of birds; based on species specific melting profiles and fractionation of sequen...
متن کاملSequence - dependent on formation of DNA Duplexes
The nonexchangeable base and sugar protons of the octanucleotide d(G-G-A-A-T-T-C-C) have been assigned by two-dimensional correlated (COSY) and nuclear Overhauser effect (NOESY) methods in aqueous solution. The assignments are based on distance connectivities of 4 . 5 A established from NOE effects between base and sugar protons on the same strand and occasionally between strands, aswell as,...
متن کاملX-ray conformational study of the DNA duplex in solution.
Earlier x-ray studies on dissolved linear DNA molecules were interpreted on the assumption that the molecules scattered as rigid rods. Improvement in equipment and advances in theory of the scattering from randomly oriented helices prompted us into a reinvestigation of this problem. Careful measurements were made on the scattering from both linear calf thymus DNA and from circular plasmid COP60...
