objectives the overall goal of this study was to carry out a set of comparative analyses of arsr gene in plasmid r773 and bacterial chromosome from escherichia coli bl-21(de3). methods pdb and ncbi databases and chimera, mega4, clc main workbench software and 3d-jigsaw and embl-ebi servers were applied to perform this study. by using these software and servers, multiple analyses including deter...
Gas extraction in the pressure-relief area using depressurization effect of seam mining is an effective way to solve coal-mine gas problems. In this paper, we performed numerical modelling 204 working face via FLAC 3D, by which stress variation rock mass and associated permeability evolution during advancement were investigated. Furthermore, favorable zone for pressure relief was proposed based...
هایی است که در مورد روش های حفاری آن انجام گرفته است. روش های مختلفی به منظور حفر و احداث تونل ها اعم از تونل های شبکه مترو، راه آهن، انتقال آب، صنعتی، معدنی و غیره وجود دارد. این روش ها به دو دسته کلی حفاری سنتی و مکانیزه طبقه بندی می شوند. حفاری سنتی در نواحی شهری عمدتا شامل روش های کند و پوش (cut & cover)، پوش و کند (cover & cut) و روش جدید حفاری اتریشی (natm) می باشد. مورد مطالعاتی مورد نظر...
PRO3D tackles two important 3D technologies, that are Through Silicon Via (TSV) and liquid cooling, and investigates their consequences on stacked architectures and entire software development. In particular, memory hierarchies are being revisited and the thermal impact of software on the 3D stack is explored. As a key result, a software design flow based on the rigorous assembly of software co...
background: 3dcrt (three-dimensional conformal radiotherapy) and imrt (intensity-modulated radiotherapy) has provided us with tools to delineate the radiation dose distribution of tumor targets. however, the precision of radiation can be compromised by respiratory motion, which usually limits the geometric and dosimetric accuracy of radiotherapy. the purpose of this study is to evaluate the imp...
conclusions our study demonstrated that 3d tvs has a good efficacy and reliable agreement with hysteroscopy in diagnosis of uterine lesions among infertile women. therefore, it can decrease the number of diagnostic hysteroscopies. results totally, 153 women were recruited in the investigation. patients aged 30.78 ± 4.79 years in average and the duration of infertility was 4.2 ± 2.91 years among...
introduction: excessive temperature rise during drilling of the mandible for dental implant placement might damage adjacent osseous tissues. various factors affect temperature rise, including the geometrical parameters of surgical drills, one of which is the drill bit head angle. the aim of this research was to determine suitable drill bit head angle to induce minimum temperature rise during ma...
