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. ...
Methemoglobin formation in human erythrocytes by nitroaromatic explosives.
We have examined the structure-activity relationships in methemoglobin (MetHb) formation by high explosives 2,4,6-trinitrotoluene (TNT), 2,4,6-trinitrophenyl-N-nitramine (tetryl) and 2,4,6-trinitrophenyl-N-nitraminoethylnitrate (pentryl), and a number of model nitrobenzenes. In lysed human erythrocytes the rate constants of oxyhemoglobin (OxyHb) oxidation increased with an increase in single-el...
متن کاملThe role of catalase in protecting erythrocytes against methemoglobin formation.
Some mechanisms to reduce methemoglobin (metHb) formation for the maintenance of normal oxygen transport have been proposed. To study the role of catalase (EC 1.11.1.6), metHb formation in the hemolysate of normal and Japanese acatalasemic human subjects were examined spectrophotometrically. Significantly increased level of metHb was induced by potassium ferrocyanide in the hemolysate of acatal...
متن کاملRates of Progression in Diabetic Retinopathy During Different Time Periods
OBJECTIVE This meta-analysis reviews rates of progression of diabetic retinopathy to proliferative diabetic retinopathy (PDR) and/or severe visual loss (SVL) and temporal trends. RESEARCH DESIGN AND METHODS This systematic literature review and meta-analysis of prospective studies assesses progression of retinopathy among diabetic patients without treatment for retinopathy at baseline.

متن کاملTracheal Chondrosarcoma Excised With Extracorporeal Circulation
Introduction: Tracheal chondrosarcoma (TCS) is a rare malignancy, with only 19 cases described in the literature to date. Case presentation: Herein, we presented the third-largest TCS with such an airway compromise that neither orotracheal intubation nor jet ventilation or even tracheostomy was possible. So, extracorporeal circulation was needed to excise the tumor in a one-stage procedure. Th...
