Research ArticleOpen accessEvery word in the titleLaboratory 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 accessEvery word in the titleManganese Uptake By Facultative and Obligate Wetland Plants Under Laboratory ConditionsA. E. Ghaly, A. Snow, M. KamalThe effect of initial concentrations of manganese on the overall removal efficiency of Mn by wool grass, soft rush, broad leaved cattail and soft stem bulrush plants was investigated under laboratory conditions. The translocation of Mn in the roots, stems, leaves and flowers of each plant species was determined and the fraction of Mn removed by precipitation was calculated. The … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 8,271 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparative Study by Electrochemical Impedance Spectroscopy (EIS) On The Corrosion Resistance of Industrial and Laboratory Zinc CoatingsY. Hamlaoui, F. Pedraza, L. TifoutiIn this work, corrosion monitoring of Zn-based coatings is investigated through potentiodynamic and electrochemical impedance spectroscopy (EIS) methods. The first part of the study is devoted to galvanised coatings conventionally manufactured in the industry. The second part focuses on the corrosion resistance of a laboratory-made electrolytic coating. For such purpose, the corrosion behaviour is studied in NaCl media under various … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,594 accessesView PDFCite
