background: this study describes the possibility of implementing three-dimensional printing technology to create a precise construction of a planned bolus, based on computed tomography information stored in the digital imaging and communications in medicine (dicom) format file. materials and methods:  to create the bolus with a 3d printer, we converted data in the dicom format to the stereolith...

انحراف در رهبری جامعه نوپای اسلامی منجر به انحراف در احکام و سیاست‏ها شد. مسلمانان که در عصر پیامبر طبق دستورات قرآن و آموزه‏های نبوی عمل می‏کردند، با رفتارهایی از سوی حاکمان مواجه شدند که در تناقض با کتاب و سنت نبوی بود و بتدریج عنوان سنت یافت و مقبولیت عامه را بدست آورد. این رفتارها در قالب احکام عبادی، سیاسی، اقتصادی و اجتماعی قابل بحث و بررسی است. در مقابل سنتهای غلط که بدعت نامیده می‏شوند،...

Globally, all activities and industries have been affected by the Fourth Industrial Revolution (IR4.0), which is ascribed to fusion of physical, digital, biological worlds. Whether they are in printed or digital form, media business must embrace new revolution not an exception. Since were already well-established electronic environment before introduction I.R. 4.0, online news portals presently...

The competitive academic atmosphere of the higher education worldwide along with the current trend in producing research-oriented knowledge by universities has made research publication the first priority for doctoral students. In this study, we addressed the conceptions of purpose, process, and product of publishing research articles among Iranian doctoral students of applied linguistics. To t...

In this paper, we propose a physically based model for the printing process in the virtual woodblock printing for improvement of printing quality. Virtual printing is a simulation of real printing using “woodblocks”, “a paper sheet”, “a BAREN (Japanese squeegee)”, and “inks” in a virtual 3D space. A print is synthesized by an interaction among them, and it is very important to study physical pr...

Electrohydrodynamic (EHD) jet printing is a direct-writing technique which ejects ink through a fine nozzle using an electric field, which has the advantages of high-resolution, rapid printing speed and a wide range of ink selectivity. In this article, the EHD jet printing system is utilized to print patterns of polystyrene (PS) nanofibers. The effect of parameters such as ink concentration, wo...

Interest in 3D printing has greatly increased since 2013. With 3D printing high part complexity at no additional costs can be achieved, beside of efficiently using the raw material. This article reviews recent developments in 3D printing, with respect to the use of wood. Three examples are given on how wood could come to 3D printing: development of bio-based filaments, printing wood-like 3D obj...

Abstract—The objectives of this research are to produce prototype coconut oil based solvent offset printing inks and to analyze a basic quality of printing work derived from coconut oil based solvent offset printing inks, by mean of bringing coconut oil for producing varnish and bringing such varnish to produce black offset printing inks. Then, analysis of qualities i.e. CIELAB value, density v...

Transfer printing is a nanofabrication technique that involves an assembly process by which a printable layer can be transferred from a transfer substrate to a device substrate. Future application of transfer printing toward a roll-to-roll printing process of flexible devices hinges upon the understanding on the mechanisms governing transfer printing quality, which is far from mature. So far, t...
