Research ArticleOpen accessIn the abstractKey Factors in the Face Stability Analysis of Shallow TunnelsDaniel Dias, Pierpaolo OresteStability of the excavation face in shallow tunnels and in poor ground is at present a relevant problem in tunnelling. A new calculation procedure is illustrated in this study for the analysis of the effect on the face stability in shallow tunnels of the following key factors: pre-support structures, presence of groundwater, free length of the tunnel (length of the … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 7,017 accessesView PDFCite
Research ArticleOpen accessIn the abstractDIFFERENT APPROACHES TO CRYSTALLIZATION OF MEMBRANE PROTEINSPrakash G. Doiphode, Vivek Pratap SinghCrystallography is more like an art than science. Crystallizing membrane proteins are a big challenge; membrane proteins are present in the cell membrane and serve as cell support. The most important feature of membrane protein is that it contains both hydrophobic and hydrophilic regions on its surface. They are generally much more difficult to study than soluble proteins. The problem … …OnLine Journal of Biological Sciences, Vol. 12, Issue 3 · 18 Dec 2012 · 7,288 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Model of Pulpit Conservation and Revitalization Using Community Participation of Phu-Thai People in Northeast ThailandBunkoet Laomi, Songkoon Chantachon, Niyom WongphongkhamProblem statement: This thesis aimed to examine the following issues of the pulpits: (1) background of the model and structure, (2) current conditions and problems of pulpit construction using participation of Phu-thai people in northeast Thailand and (3) model of conservation of revitalization of pulpits by participation of Phu-thai people. Approach: Data were collected from documents and field study in … …Journal of Social Sciences, Vol. 5, Issue 4 · 31 Dec 2009 · 7,917 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Convergence-Confinement Method: Roles and Limits in Modern Geomechanical Tunnel DesignPierpaolo OresteThe convergence-confinement method, based on the analysis of the stress and strain state that develops in the rock around a circular tunnel, has been presented in this study with the two analytical solutions that have been most frequently used in recent years. Problem statement: Thanks to the increased power of electronic processors and the spread of numerical methods, the role … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 10,151 accessesView PDFCite
EditorialOpen accessIn the abstractVolume 1: First Steps for SGAMRChiara Bedon, Mario D’Aniello, Flavio StochinoSummer 2017 is approaching when the International Journal of Structural Glass and Advanced Materials Research starts to walk and the “Volume 1” contains its first outcomes (Bedon et al., 2017). It is worth of interest that the attention of the contributors is on glass…. but not only,… and this represents a promising step for the journal growth and evolution. In … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 28 Aug 2020 · 6,331 accessesView PDFCite
HypothesisOpen accessIn the abstractCan Anthocyanins be Part of the Metal Homeostasis Network in Plant?Marco LandiAnthocyanins are a class of flavonoids with a high level of diversification and likely the most studied pathway of secondary metabolism in Plantae. Anthocyanins have raised a growing interest due to the huge variability of their chemical structures and the more new anthocyanins are isolated from plants, the more questions on their evolutionary and ecological meaning they raise. Antioxidant, photoprotection … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 4 · 9 Dec 2015 · 8,568 accessesView PDFCite
HypothesisOpen accessIn the abstractIncreased Tissue Pressure Induces Demyelinated Lesions and Necroses in the BrainHelmut Barz, Ulrich Barz, Almut SchreiberA general brain edema increases the size of the brain tissue and stretches the elastic neuronal and glial fibers. Myelinated fibers are more elastic than unmyelinated fibers. The stretching of the neuronal fibers leads particular in regions of the white matter or areas surrounded by myelinated fiber tracts to an increased tissue pressure. This physical principle can be the reason … …Neuroscience International, Vol. 6, Issue 1 · 30 Mar 2015 · 7,424 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermining Potential Sites for Runoff Water Harvesting using Remote Sensing and Geographic Information Systems-Based Modeling in SinaiHossam H. Elewa, Atef A. Qaddah, Ayman A. El-FeelProblem statement: Sinai is increasingly suffering from an overwhelming water crisis. Runoff Water Harvesting (RWH) could be a solution for this problem. The determined promising drainage basins for RWH could be used by the decision makers to propose appropriate controlling systems to overcome the problem of water scarcity and for implementing runoff farming and rain-fed agriculture. Approach: Remote sensing, geographic … …American Journal of Environmental Sciences, Vol. 8, Issue 1 · 15 Feb 2012 · 8,483 accessesView PDFCite
Research ArticleOpen accessIn the abstractCrystal Structure of 2-(4-Hydroxy-3-Methoxyphenyl)-6- (4-Hydroxy-3-Methoxystyryl)-1-Methyl-2, 3-Dihydropyridine-4 (1H)-One by X-Ray Powder DiffractionBahjat A. Saeed, Kawkab Y. Saour, Rita S. Elias, Deng XiaodiProblem statement: The studied dihydropyridone was synthesized for the first time via the microwave assisted reaction of curcumin and methylamine and it is important to support the mechanism by the crystal structure. Approach: The crystal structure of the title compound was determined using high resolution x-ray diffraction. PowderSolve program was used to solve the structure while the refinement was done … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 7,160 accessesView PDFCite
