The nonword repetition (NWR) test has been shown to be a good predictor of children's vocabulary size. NWR performance has been explained using phonological working memory, which is seen as a critical component in the learning of new words. However, no detailed specification of the link between phonological working memory and long-term memory (LTM) has been proposed. In this paper, we present a...

امروزه به دلایل مختلف رشد جمعیت از یک طرف و گسترش صنایع و کشاورزی از طرف دیگر، کنترل کیفیت منابع آب مورد توجه قرار گرفته است . مواد آلی موجود در آب میتواند از منابع گوناگونی چون فاضلابهای خانگی کاملا تصفیه نشده و فاضلابهای صنعتی یا کشاورزی ناشی شود. در حال حاضر گزارشات نشان میدهند کهدر بسیاری از نقاط دنیا ترکیبات آلی فرار (vocs) از جمله مواد آلی هستند که بعضا در آبهای سطحی و زیرزمینی مشاهده شده...

In the considered foundry emits offgas containing VOCs (especially ethanol). In order to reduce the VOC content, a compost based biofilter has been installed. In this approach, the polluted air stream enters a pre-conditioning chamber where temperature and humidity is adjusted for asphalt factories. Biofilteration has already been well established as an air pollutant control alternative. There ...

With a market share of over 50%, Deluxe Corporation was the largest printer of checks and related financial forms in the United States. The lithographic printing process the company had been employing at about 50 facilities in the U.S. resulted in significant volatile organic compound (VOC) emissions regulated by the Clean Air Act. Although conventional inks contained VOCs that contributed to t...

Up to now the limited knowledge about the exchange of volatile organic compounds (VOCs) between the biosphere and the atmosphere is one of the factors which hinders more accurate climate predictions. Complete long-term flux data sets of several VOCs to quantify the annual exchange and validate recent VOC models are basically not available. In combination with long-term VOC flux measurements the...
