Research ArticleOpen accessPhrase in the titleAlnus subcordata C.A.M. Cambium Cells Dynamics Along Transport Corridors in Hyrcanian ForestsAidin Parsakhoo, Hamid Jalilvand, Mehdi SheikhiProblem statement: In this study, we considered transport corridors and sampling aspects to be the major indicators of ecological effects on Alder (Alnus subcordata) cambium cells dynamics. Approach: Thus, 240 cores were taken from forest-facing and road-facing trunk of Alder trees along Amre, Neka and Darab Kola transport corridors in hyrcanian Forests of Iran. Results showed that the roads corridor … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 6,950 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSensitivity Analysis of an Optimal Access Road Location in HillyForest Area: A GIS ApproachMohd I. Hasmadi, J.C. TaylorThere are various models for establishing the efficient forest road allocation and evaluating optimum density of forest roads network for the transport of timber commodity. Most of them are based on the calculation of common timber transport costs and costs for forest roads. Today, forest road design from traditional method continues to be transformed by remote sensing technology and advancement … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,609 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCritical Retrospect on Conventional and Luminescent Solar Concentration DevicesHamzah Abdul-Rahman, Chen WangProblem statement: Conventional solar concentrators are only sensitive for the beam radiation and they function poorly in overcast sky conditions. Even under a clear sky condition, trackers are always needed for conventional solar concentrators. Static concentrators always come with a poor concentration rate without a tracker and the light concentrated by normal Luminescent Solar Concentrators (LSC) could not be transported … …American Journal of Environmental Sciences, Vol. 6, Issue 5 · 31 Oct 2010 · 6,924 accessesView PDF Cite
