If a carpet is put under pressure during use or storage, its thickness decreases instantly and continues to decrease slowly as the pressure is not removed. Some part of this loss of thickness is not recoverable. This phenomenon is called creep and is influenced by parameters such as temperature and humidity, and it may cause breakage, burst, crease, bump, and folding line in the carpet. By stud...
the solutions of mathematical models for the estimation of the kinetic, and biokinetic parameters of naphthalene, anthracene and pyrene during degradation in surface and subsurface soils are presented in this work. the models were developed using the twin concepts of rate-determining step and steady-state approximation method. they described the biodegradation of single and a mixture of polycyc...
Creep behavior of the weldment a new type martensitic heat-resistant steel 12Cr10Co3W2MoNiVNbNB joined with vacuum electron beam welding is studied employing nano-indentation technique at room temperature. Different load-displacement curves are obtained for base metal, heat affected zone (HAZ) and weld metal welded joint. The creep displacement exhibits sharp rise first, then rate continuously ...
در مطالعه عمیق روی توزیع زاویه ای پاره های شکافت در واکنش یون سنگین ناهمسانگردی های زیادی دیده شده است. این ناهمسانگردی ها را می توان توسط نظریه استاندارد آماری (tsm)(transition statistical state model) توضیح داد.46علت وجود این ناهمسانگردی ها را می توان به اسپین بالا یا z2/a هسته شکافت پذیر نسبت داد1. برای ناهمسانگردیهای بیشترمی -توان از مدل آماری انقطاع (ssm)استفاده کرد. در این مدل توزیع تصویر...
