many constants and coefficient effect on the modeling results. in many cases, it is possible these constants and coefficients differ from their real values in the environment, but the modeling results adapted with real boundary conditions due to other factors adjustment during modeling. uncertainty analysis is a tool for assessing the effect of uncertainty of various factors on the modeling res...
Improved magnetic characters of graphene oxides besides its unique biocompatibility make this compound as a theranostics agent could be so practical in the medicine fields. Oxygen functionalities with disturbing the symmetry of graphene sublattices could induce magnetic moments and improve magnetic properties in these structures. While that, vacancies and distortions, created by oxygen release...
introduction: diabetes mellitus is a global public health issue that has a prevalence of between 5-8% in different parts of iran. one of the most serious complications of diabetic foot ulcer and chronic complications of diabetes mellitus is one of the leading causes of morbidity and amputation in patients with diabetes. on the other hand, amputations in patients with diabetes are three-year sur...
the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
مقدمه و هدف : یکی از عوامل مهم و تاثیرگذارجهت دستیابی به انطباق بدون تنش در پروتزهای متکی بر ایمپلنت، انجام قالبگیری دقیق می باشد. دو روش قالبگیری مستقیم و غیرمستقیم برای انتقال موقعیت ایمپلنت از دهان به کست کار وجود دارد. هدف از انجام این مطالعه بررسی دقت وسایل رایج جهت قالبگیری به روش غیرمستقیم درسه نوع سیستم مختلف ایمپلنت دندانی و مقایسه آنها با روش مستقیم می باشد. مواد و روش ها : در...
the hybrid molten/solid in2o3 - 30-48 wt.% bi2o3 oxide materials were studied with respect to their transport properties. the conductivities, oxygen ion transport numbers and oxygen permeation fluxes have been measured by using the four-probe dc, volumetric measurements of the faradaic efficiency and gas flow techniques, respectively. we show that the oxygen permeability of the hybrid molten/so...
Introduction: The toxicity of gentamycin in the kidney seems to be related to the generation of reactive oxygen species (ROS). There is evidence that pretreatment with oxygen increases the rate and activity of antioxidant enzymes. Methods: In this experimental study, forty eight female rats (Sprague Dawlley) were divided into 6 groups randomly (8 in each) as follows: group 1 was the control an...
Background and purpose: Hypoxemia and hypotension are important complications of hemodialysis in patients with chronic renal failure that are linked to several factors, including the type of filters used. The aim of this study was to compare the effect of simple filtration hemodialysis and ultrafiltration hemodialysis on blood pressure and blood arterial oxygen level. Materials and methods: In...
Using a balloon-borne 60 cm telescope equipped with an SIS receiver we have searched for the 425 GHz molecular oxygen line in the NGC7538 and the W51 regions. The experiment was technically successful (confirmed by the detection of the 13 CO (4–3) line at 440 GHz), but we failed to detect emission from molecular oxygen. The inferred upper limits of the O 2 /CO ratio are 0.04 and 0.05 (3 σ) for ...
