Research ArticleOpen accessIn the keywordsThe Wear of Tunnel Boring Machine Excavation Tools in RockClaudio Oggeri, Pierpaolo OresteSome of the most important aspects in the study of the fragmentation of rock due to the action of TBM disks concern the abrasiveness of the rock and the wear of the tools. The wear of the disks in fact means that they have to be substituted, with consequent effects on the efficiency of the excavation, on the speed of … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 16 Aug 2012 · 7,654 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsThe Determination of the Tunnel Structure Loads Through the Analysis of the Interaction between the Void and the Support Using the Convergence-Confinement MethodPierpaolo OresteThe evaluation of the load acting on a tunnel support is of fundamental importance for the correct dimensioning of the structure when analytical calculation methods are used. The load acting on the support depends on various factors and for this reason its evaluation can appear somewhat complex. One way of evaluating the load acting on a support is to use … …American Journal of Applied Sciences, Vol. 11, Issue 11 · 7 Jan 2015 · 6,808 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsMorphological Characterization and Variation in the Total Content of Reducing Sugars in Wild Populations of Agave angustifolia HawMartin Esqueda, Aldo Gutierrez, Guadalupe Palomino et al.Problem statement: Bacanora, a spirit, is distilled from wild populations of Agave angustifolia Haw. Loss of biodiversity must be taken into account when proposing sustainable management actions for this resource. In this study we identified the morphological variants of this species, as well as the weight and Total Content of Reducing Sugars (TRS) in the stem of the agave. Approach: … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 21 Oct 2011 · 8,553 accessesView PDF Cite
