Research ArticleOpen accessIn the abstractInvestigating Effects of Water Conditioning on the Adhesion Properties of Crack SealantAhmed Lamarre, Elham H. Fini, Taher M. Abu-LebdehThis paper investigates the effect of water exposure on three different crack sealants commonly used in cold, moderate and hot climates. It is hypothesized that water penetrates into the interface between crack sealant and substrates causing progressive adhesion failure and that the rate of failure varies depending on the sealant’s surface chemistry as relates to its interaction with water molecules … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 14 Mar 2016 · 8,778 accessesView PDFCite

Research ArticleOpen accessIn the abstractEcological Studies of Epiphytic Microalgae and Epiphytic Zooplankton on Seaweeds of the Eastern Harbor, Alexandria, EgyptN. G. Shams El-Din, N. A. Shaltout, M. Z. Nassar, A. SolimanA qualitative and quantitative study on the epiphytic microalgae and epiphytic zooplankton were conducted in order to follow up their community structures on seaweeds in relation to some physico-chemical variables in the coastal waters of the Eastern Harbor of Alexandria. Water and macroalgal samples were collected seasonally during two years successively: Winter, summer, autumn (2012) and spring (2013).
