هنگام استفاده از مصالح خرده آسفالت در بازیفات گرم لازم است این مصالح در فرایند تولید در کارخانه و همچنین در فرایند طرح اختلاط در آزمایشگاه حرارت داده شوند هدف از حرارت دهی مصالح خرد اسفالت تغییر حالت قیر موجود در خرده آسفالت از حالت سخت و جامد به حالت نرم و مایع و به تبع آن جدا نمودن مصالح سنگی از یکدیگر است بگونه ای که مصالح سنگی آزاده شده بتوانند در جریان عمل اختلاط بطور کامل در سرتاسط مخلوط ...
CoHErrelation between weldability and improvement in properties is a key issue in materials science research. The objective of this work is to optimize the process parameters viz., aging temperature, aging time, solutionizing time, to enhance the hardness of Al6061 alloy. Hence, the present paper deals with hardness study of Tungsten Inert Gas welded 6061 aluminium alloy after age hardening und...
Physical property comparison of 11 soft denture lining materials as a function of accelerated aging.
Soft denture-lining materials are an important treatment option for patients who have chronic soreness associated with dental prostheses. Three distinctly different types of materials are generally used. These are plasticized polymers or copolymers, silicones, or polyphosphazene fluoroelastomer. The acceptance of these materials by patients and dentists is variable. The objective of this study ...
BACKGROUND Globally, ageing impacts all countries, with a majority of older persons residing in lower- and middle-income countries now and into the future. An understanding of the health and well-being of these ageing populations is important for policy and planning; however, research on ageing and adult health that informs policy predominantly comes from higher-income countries. A collaboratio...
A critical issue concerning the deterioration of ageing road infrastructure all around the world is the need to rapidly and cost-effectively evaluate the present condition of pavement infrastructure. Non-Destructive Test (NDT) and evaluation methods are well-suited for characterizing materials and determining structural integrity of pavement systems. The Falling Weight Deflectometer (FWD) is a ...
PURPOSE The purpose of this study was to investigate the effect of different plasticizing aging solutions on wear resistance and hardness of selected universal resin-based dental composites. METHODS Three light cured (one nanofilled, two microhybride) and one hybride chemical cured composites were aged at 37 °C for 48 h in distillated water, ethyl alcohol solution or Listerine mouthwash. Afte...
specific variations in sarcoplasmic proteome influence beef color. Post-mortem aging is a common practice employed by beef industry for improving beef tenderness and palatability. However, the color attributes and sarcoplasmic proteome of beef muscles undergo changes during aging. The objective of this study was to examine the changes in the sarcoplasmic proteome profile of three differentially...
This article presents a series of experimental investigations on the viscoelastic behavior silica-filled and silver-filled silicone rubber unaged aged states. The study specific aging conditions relative to electronics industry is proposed in this work, namely hermetic, initially inert atmosphere, at high temperatures. Viscoelastic properties materials are measured through DMA tests. Strain swe...
