Al Qadi, Mahmoud B.A. Alhasanat, Madhar HaddadThis research has used crumb rubber in asphalt mixture as a part of the coarse and fine aggregate. Three sieve sizes of crumb rubbers were used in asphalt mixture No. 4, No. 8 and No. 50, with five percent of asphalt cements (4, 4.5, 5, 5.5 and 6%) by weight and four percent of crumb rubbers (10, 20, 30 and … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 24 Jun 2016 · 9,525 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImpact of the Use of Object Request Broker Middleware for Inter-Component Communications in C6416 Digital Signal Processor Based Software Communications Architecture Radio SystemsWael A. Murtada, Mohamed M. Zahra, Magdi Fikri et al.Problem statement: This study presents an in-depth analysis of the performance of Software Communications Architecture (SCA) component-based waveform applications in terms of inter-component communications. The main limitation with SCA, in the context of embedded systems, is the additional cost introduced by the use of Object Request Broker (ORB) middleware. The ORB middleware handles the interaction between components and objects in … …Journal of Computer Science, Vol. 8, Issue 6 · 3 Apr 2012 · 7,239 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIrrationality in the Neoclassical Definition of RationalitySteve KeenIn this study we are not arguing that competition as it actually occurs in practice is not socially beneficial. Our criticism is directed instead at the false belief that rational profit-maximizing behavior and competition as defined by neoclassical economic theory will lead to a welfare-maximizing outcome-again, as defined by neoclassical theory. …American Journal of Applied Sciences, Vol. 2, Issue 13 · 18 Dec 2005 · 8,302 accessesView PDFCite

Forty eight (48) "Spanish" kids and 28 Brangus calves were randomly divided into four treatment groups; goats grazing alone (GOA, control), Goats Followed by Cattle (GFC), … …American Journal of Animal and Veterinary Sciences, Vol. 10, Issue 3 · 8 Jun 2015 · 7,537 accessesView PDFCite
Research ArticleOpen accessIn the author namesEffects of Short Term in vitro Stress Hormone Exposure on Regulatory T Cell Number and Function in AsthmaKristina E. Rehm, Gailen D. Marshall, Jr.Asthma is characterized by alterations in the immune system, including regulatory T cells (Treg). Further alterations in Treg numbers and/or function caused by stress hormones may be a contributing factor in asthma pathogenesis. We compared Treg populations and the effects of Dexamethasone (DEX, a laboratory analog of cortisol) on Treg cell number and function in patients with asthma and a … …American Journal of Immunology, Vol. 11, Issue 1 · 24 Apr 2015 · 6,608 accessesView PDFCite
