Research ArticleOpen accessIn the abstractLaboratory Investigation of the Biology of Bactericera tremblayi Wag. (Homoptera: Triozidae) a New Pest in Onion Fields of IranMohammad Hossein. Kazemi, Mohammad Mashhadi JafarlooProblem statement: Psyllids as a small group of insects with plant feeding adult and nymphal stages, not only could have direct feeding damages but they could also transmit plant diseases especially viruses. Bactericera tremblayi had recently increased to high densities in onion fields in East Azarbaijan province in Iran and the pest had become widespread. This was the first study … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 7,501 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Provenance of the Varzaneh Aeolian Sand Field Regarding to Lithology and Texture, SW Esfahan, IranH. Pakzad, R. AjalloeianThe main mineralogical/lithological composition of the Varzaneh aeolian sands is sedimentary and igneous lithics. The minor one is metamorphic lithics and mineral grains (such as quartz, feldspar and heavy mineral grains) respectively. The origin of the sedimentary lithics (mainly carbonates) mostly is from sedimentary rocks exposed in the west and the southwest of the study area. These rocks belong to … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,199 accessesView PDFCite
Research ArticleOpen accessIn the abstractThickness Analysis of Stone Mastic Asphalt (SMA) Slab Compacted Using a Newly Developed Roller CompactorR. Muniandy, F.M. Jakarni, S. Hassim, A.R. MahmudPavement mix design procedures and specifications are usually derived from laboratory experiments. Therefore, laboratory experiments should be able to simulate to a high degree the conditions in the field, especially in term of compaction procedures. Based on literature reviews and analysis of past studies, it can be concluded that there are no exact method for laboratory compaction that can simulate … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,476 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Application of Finite Element Modelling to Pneumatic Artificial MuscleR. Ramasamy, M. R. Juhari, M. R. Mamat et al.The purpose of this article was to introduce and to give an overview of the Pneumatic Artificial Muscles (PAMs) as a whole and to discuss its numerical modelling, using the Finite Element (FE) Method. Thus, more information to understand on its behaviour in generating force for actuation was obtained. The construction of PAMs was mainly consists of flexible, inflatable membranes … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 7,663 accessesView PDFCite
Research ArticleOpen accessIn the abstractCost Comparison between Stone Mastic Asphalt and Asphalt Concrete Wearing CourseSalihudin Hassim, Rohimah Khoiriyah Harahap, Ratnasamy Muniandy et al.Stone Mastic Asphalt (SMA) technology has been introduced to Malaysia since the 1990’s. Since then, several trials had lain projects had been initiated for the purpose of evaluating the mix on local road condition. However, the acceptability of SMA is still quite discouraging among the local road authorities. This setback is probably due to the misconception on the high initial … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 7,015 accessesView PDFCite
