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. ...
A multiscale model of atomic layer deposition (ALD) inside a nanoporous material is developed in this paper. The overall model couples lattice Monte Carlo simulators describing molecular-scale growth of the ALD film to a continuum description of the precursor transport within the nanopore. The multiscale simulator is used to study how intra-pore precursor depletion leads to nonuniform ALD films...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
X-adrenoleukodystrophy (X-ALD) is an inherited fatty acid metabolic disorder with secondary manifestation of neuroinflammatory disease process. We report that compounds (forskolin, 8-bromo cAMP, and rolipram) that increase cAMP and activate protein kinase A (PKA) were found to stimulate the peroxisomal beta-oxidation of lignoceric acid (C24:0) whereas compounds (H-89 and myristoylated PKI) that...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
Thin film Cu(In,Ga)Se2 solar cells with ALD-deposited Zn1–xSnxOy buffer layers are fabricated and the solar cell properties are investigated for varying ALD deposition temperatures in the range from 90 °C up to 180 °C. It is found that a process window exists between 105 °C and 135 °C, where high solar cell efficiency can be achieved. At lower ALD deposition temperatures the solar cell performa...
BACKGROUND Though the type of alcohol consumed is not thought to be associated with alcoholic liver disease (ALD), some studies have shown a beverage-specific effect. In the present study, we aim to study the effects of locally brewed alcoholic beverages on the development of liver disease. PATIENTS AND METHODS This cross-sectional study was conducted at the internal medicine department of a ...
despite the different criticisms on contrastive analysis it has been proved that the results of it(when processed) can be useful in a tefl environment, specially at the level of phonology.this study is an attempt to compare and contrast the sound systems of kurdish and english for pedagogical aims.the consonants,vowels,stress and intonation of the two languages are described by the same model...
Previous research on the laser damage resistance of thin films deposited by atomic layer deposition (ALD) is rare. In this work, the ALD process for thin film generation was investigated using different process parameters such as various precursor types and pulse duration. The laser-induced damage threshold (LIDT) was measured as a key property for thin films used as laser system components. Re...
Convincing evidence links aberrant B-vitamin dependent hepatic methionine metabolism to the pathogenesis of alcoholic liver disease (ALD). This review focuses on the essential roles of folate and vitamins B6 and B12 in hepatic methionine metabolism, the causes of their deficiencies among chronic alcoholic persons, and how their deficiencies together with chronic alcohol exposure impact on aberr...
