concrete is the most common material used to line irrigation canals and must maintain its durability for the lifetime of the canal. compressive strength has been used as an index to control the quality of concrete; concrete that remains durable under freeze-thaw conditions is that with high compressive strength. research has shown that concrete linings can show suitable compressive strength in ...
در دو دهه گذشته پردازنده ها (dsp processor) ، بازار تراشه های همه منظوره محاسبات dsp را در اختیار داشته اند . پیشرفت در ساخت مدارهای دیجیتال ، افزایش تعداد گیتهای منطقی قابل پیاده سازی در یک تراشه را در پی داشته است . به نظر می رسد پردازنده ها (programmable architecture) امکان حداکثر بهره برداری از این ظرفیتهای جدید را نداشته و نیاز به بازنگری دارند. معماری بازپیکرپذیر (reconfigur...
this paper seeks to investigate a new definition for architecture by unifying the three vitruvian principles of firmitas, utilities, and venustas via a phenomenological approach in the interpretation and analysis of their role in defining architecture. the paper is composed in two main sections. the first section investigates the nature of architecture based on the mentioned principles, where a...
In order to assess mineralogical composition influence on durability and strength of rocks, four samples of hornfelsic rocks were selected from southern and western parts of the city of Hamedan, west of Iran. These rock samples were subjected to mineralogical, physical and mechanical tests in the laboratory. Also, they were evaluated in 15 cycles of slake-durability testing in different pH of s...
Wound matrix materials are used to improve the regeneration of dermal and epidermal layers in both acute and chronic wounds. Contemporary wound matrices are primarily composed of biologic materials such as processed xenogeneic and allogeneic tissues. Unfortunately, existing biologic wound matrices possess multiple limitations including poor longevity, durability, strength, and enzymatic resista...
A review of several past studies clearly shows the effect of reduced air voids on improved fatigue and rutting performance of asphalt mixtures, both in the laboratory and field. Depending on mix type and experiment (which included constant-stress bending beam fatigue testing and field results from WesTrack), fatigue performance improved between 8.2 and 43.8% with a 1% decrease in air voids. Lik...
a research program was conducted on different clay-bearing rocks selected from the ilam, sarpol-e zahab and tajarak regions (iran) to predict their slaking characteristics. the new durability apparatus (nested mesh drums) separates disintegrated particles varying from > 25.4 to < 2 mm as the drums were rotated. on the basis of the particle size distribution, the disintegration ratio (dr) was us...
Background: The durability of physicians working in the family physician program is one of the most important factors in effective implementation of this program. This study aimed to investigate the individual, organizational, and environmental factors affecting the family physicians' durability in Rafsanjan University of Medical Sciences in 2019. Methods: This descriptive-analytical study was...
