We compared the electrophysiological correlates for the maintenance of non-musical tones sequences in auditory short-term memory (ASTM) to those for the short-term maintenance of sequences of coloured disks held in visual short-term memory (VSTM). The visual stimuli yielded a sustained posterior contralateral negativity (SPCN), suggesting that the maintenance of sequences of coloured stimuli en...

Health care provides many opportunities in which the sharing of data between independent sites is highly desirable. Several standards are required to produce the functional and semantic interoperability necessary to support the exchange of such data: a common reference information model, a common set of data elements, a common terminology, common data structures, and a common transport standard...

OBJECTIVES Extension of the standard model while retaining compliance with it is a challenging issue because there is currently no method for semantically or syntactically verifying an extended data model. A metadata-based extended model, named CCR+, was designed and implemented to achieve interoperability between standard and extended models. METHODS Furthermore, a multilayered validation me...

Since decades the evaluation of flaw indications on radiographs from welds or castings are based on well accepted reference film catalogues from organizations like IIW (weldments), ASTM (castings) or DGZfP (D5 recommendation on heavy steel castings). Today, the transformation of classical film radiography to the digital world is in full progress. Some ASTM standards do not permit the evaluation...

هدف از این پژوهش بررسی اثر نانوذرات اکسید روی بر خواص فیزیکوشیمیایی و ضد میکروبی فیلم‌های بایونانوکامپوزیت نشاسته سیب‌زمینی می‌باشد. در این تحقیق فیلم‌های نشاسته‌ای ساپورت شده با نانوذرات اکسید روی در غلظت‌های (0، 1، 3 و 5%) با استفاده از روش کاستینگ تهیه شد. کلیه خواص فیزیکوشیمیایی به روش استاندارد ملی آمریکا(ASTM)  و خواص ضد میکروبی به روش نفوذ بر سطح آگار و فلاسک چرخان انجام شد. خواص فیزیکوش...

In an on-going effort to increase the safety and efficiency of turbine engines, the National Aeronautics and Space Administration is exploring lightweight alternatives to the metal containment structures that currently encase commercial jet engines. Epoxy reinforced with braided carbon fibers is a candidate structural material which may be suitable for an engine case. This paper reports flat-co...

Grey cast iron of the grade ASTM 48 is in the use for manufacturing casting parts with low or middle duty or load, such as various stove parts, gas burners, boiler parts, protective cover, hand wheel, brackets, base plate, crane balls, counter weight, handle, machine base etc. The production volume rate is mainly lies with the material removal rate during machining process and this is essential...
