This paper introduces an effective production optimization and a water injection allocation method for oil reservoirs with water injection. In this method, a two-stage adaptive simulated annealing (ASA) is used. A coarse-grid model is made based on average horizon permeability at the beginning iterations of the optimization to search quickly. In the second stage, the fine-grid model is used to ...

introductionchildren with severe asthma attack are a challenging group of patients who could be difficult to treat and leading to significant morbidity and mortality. asthma attack severity is qualitatively estimated as mild, moderate and severe attacks and respiratory failure based on conditions such as respiration status, feeling of dyspnea, and the degree of unconsciousness. part of which ar...

Docolorization of Methylene Blue was investigating using a Ultrasonic/Fenton like reactor in batch mode. The effects of pH, reaction time, initial concentration of dye, H2O2 and Fe on the dye removal was studied. It was found that the increase of initial dye and H2O2 concentration and the increase of initial pH, are not beneficial for improving the dye removal efficiency. Increasing the dye con...

background: in medicine, especially in pediatrics, it is necessary to perform regular epidemiologic studies in different geographic regions. this study was performed in nemazee hospital, shiraz, southern iran to determine the gastrointestinal (gi) disease spectrum, the mortality and also the rate of matching final diagnosis with the initial impression in pediatric gi ward. â  methods: of all th...

photoreactor using solar radiation. The effect of various parameters such as pH, initial concentration of pollutant, catalyst dose, oxidant, and time variation were studied. The determination of the best catalyst was studied amongst the four catalysts (TiO2, ZnO, PSA and SSA) .The kinetics of degradation of isooctane was also studied. The results showed that TiO2 was the best catalyst with a de...

Background: This study compared the outcomes between patients with proximal humerus fractures (PHF) whounderwent acute reverse total shoulder arthroplasty (RSA) to those who underwent an alternative initial treatmentbefore requiring (secondary) RSA.Methods: Patients who underwent RSA after suffering a PHF were identified. Two year clinical follow-up was requiredfor inclusion. Patients were divi...

The aim of this work was to investigate effect of operational parameters on the photocatalytic degradation efficiency of a solution containing C. I. Basic Blue 41 BB41 in a recirculated rectangular photoreactor irradiated with a UV light. TiO_2 nano composite film was prepared via sol-gel dip coating method. The films were characterized by X-ray diffraction XRD, transmission electron microscopy...
