This paper describes optimization techniques for translating out-of-core programs written in a data parallel language like HPF to message passing node programs with explicit parallel I/O. We rst discuss how an out-of-core program can be translated by extending the method used for translating in-core programs. We demonstrate that straightforward extension of in-core compilation techniques does n...
Objectives: The aim of this study was to compare the microtensile bond strengths (µ TBS) of three core materials with one lithium disilicate reinforced ceramic using two resin cements. Methods: Three core materials (Nulite F® (Biodental Technologies), Filtek Z250® (3M-ESPE), Prettau-Anterior® (Zirkonzhan, Germany)) were prepared as blocks (10×10×4 mm3) according...
کلون سازی، تعیین ترادف و بیان ژن core ویروس هپاتیت c جدا شده از یک بیمار ایرانی مبتلا به هپاتیت مزمن
مقدمه: ویروس هپاتیت c یکی از مهمترین عوامل ایجادکننده هپاتیت حاد ومزمن، سیروز و سرطان کبد در سطح جهان محسوب می شود. به دلیل روند رو به رشد ابتلا به hcv در سطح دنیا تحقیقات گسترد ه ای در نقاط مختلف جهان برای افزایش کیفیت روشهای تشخیصی و تعیین ژنوتیپ ویروس در حال انجام است. روشها: در این تحقیق ناحیه ژنی مربوط به پروتئین نوکلئوکپسید ویروس (ژن core) که یک ناحیه بسیار حفاظت شده درطول ژنوم ویروس است،...
T his empirical analysis endeavors to trace out the causal nexus between core inflation and economic growth from the perspective of twenty worlds’ leading economy with the help of the nonlinear Granger causality approach by using time series data from 1981 to 2016. Based on nonlinear Granger causality results, it has been found that there is unidirectional casualty running from core ...
Investigation of pore system properties of carbonate reservoirs has an important role in evaluating the reservoir quality and delineating high production intervals. The current study proposes a three-step approach for pore throat size characterization of these reservoirs, by integrating core data, well logs and 3D seismic volume. In this respect, first the pore throats size was calculated using...
previous studies have aimed at testing a hypothesis but the present study is data-first research in which researcher tries to form a theory from data rather than the use of data to test a hypothesis. this study aims at exploring teachers perceptions of the strengths and weaknesses of the current syllabus for college preparatory course. eight experienced teachers were selected to collect data du...
permeability is a property of porous medium that quantifies rock capacity to transmit fluids. frequently, core based permeability data are not available either because of the borehole conditions or due to the high cost of coring. for these reasons, over the years attempts have been made to estimate permeability by alternative ways. permeability is an elusive parameter in hydrocarbon reservoirs ...
the purpose of this study was to examine the english language needs of medical students at tehran university of medical sciences . analysis of the needs took place for three groups: 320 undergraduate students, 30 postgraduate students and 20 university instructors. a triangulation approach to collect data was used in which a combination of the quantitative (using the questionnaires) and qualita...
The behavior of OPECchr('39')s main exporter, Saudi Arabia and OPECchr('39')s core members (Kuwait, Qatar, and UAE) are of concern to Iran and other oil importing or exporting countries. Excess oil production capacity of OPECchr('39')s core countries lets them to have different behavior in normal and exceptional periods. In this paper, we apply a modified griffin’s model to seasonal data for th...
One of the Siberian high pressure system is the Earth climate system, atmospheric important. The purpose of this study, analysis of core changes Siberian high pressure system in the period mentioned. To identify the core spatial variations in the timeframe mentioned data, daily sea level pressure and temperature of the earth's surface with a resolution of 2.5 degrees within the space of 30 to 6...
