Introduction: Auditory processing disorder (APD) is a type of abnormal perceptual processing of auditory information within the central auditory nervous system that could be influenced by cognitive factors, such as attention. Attention is one of most important cognitive functions in the development of learning in children, so it is important to recognize and evaluate a variety of attention defi...
Background and Aim: Microleakage has been always a major concern in restorative dentistry. The curing contraction of composites still presents a problem with controlling microleakage and postoperative sensitivity. The aim of this study was to investigate the effect of flowable and dual-cure resin composite liners on gingival microleakage of packable resin composite restorations. Materials and ...
در دهه اخیر، ساختار فراماده الکترومغناطیسی توجه زیادی را در فیزیک و جوامع مهندسی به خود جلب کرده است. فراماده ساختاری است الکترومغناطیسی با خصوصیات همگن ومصنوعی که دارای خواص غیر عادی می¬باشد. این ساختارضریب گذردهی الکتریکی منفی و ضریب نفوذپذیری مغناطیسی منفی دارد و تحت عنوان ساختار چپگرد شناخته می¬شود. ابعاد سلولی آنها از طول موج کوچکتر است. این ساختار در طبیعت یافت نمی شوند. انتشار امواج در ا...
we introduce the notions of t-dual rickart and strongly t-dual rickart modules. we provide several characterizations and investigate properties of each of these concepts. it is shown that every free (resp. finitely generated free) $r$-module is t-dual rickart if and only if $overline{z}^2(r)$ is a direct summand of $r$ and end$(overline{z}^2(r))$ is a semisimple (resp. regular) ring. it is sho...
The metabolic interrelationships between the growth of a rapidly proliferating tissue and of a transplanted tumor were investigated in the same animal. Liver regeneration and tumor growth were studied in C3H mice bearing a transplanted mam mary carcinoma. The rate of radioactive phosphorus incorporation in the DNA, RNA, and phospholipids of the liver and the tumor was deter mined at intervals o...
