Research ArticleOpen accessIn the abstractAnalysis of the Effect of Pile Skin Resistance Verses Pile Diameter Based on Experimental ResearchS. M. Marandi, M.A. KarimzadehIn spite of the many recent advances in pile design and execution methods, the quantitative effects of grouted pile skin resistance and form on subsequent pile behavior remains an area for research. There are many parameters involved in the analysis of the bearing capacity of piles and descriptive method theory of the loading effect for each parameter is very complex. … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,273 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDensification Behaviour of a Red Firing Tunisian Triassic ClayHajer Baccour, Mounir Medhioub, Fakher Jamoussi, Taher. MhiriInvestigations were undertaken to assess the thermal modification in clay products from Triassic sedimentary deposits. This study deals with the mineralogical, physico-chemical, thermal analysis and faience making attributes of representative Triassic clay in the south-Eastern Tunisia. The data collected from these techniques show that illite and kaolinite are the major clay phases. The accessory minerals detected in powdered rock are; … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 7,109 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordComparisons of Test Statistics for Noninferiority Test for the Difference between Two Independent Binominal ProportionsYouhei Kawasaki, Fanghong Zhang, Etsuo MiyaokaProblem statement: Noninferiority tests are frequently used in clinical trials to demonstrate that the response for study drugs is not much worse than the response for reference drugs. Several test statistics exist. However, a detailed comparison of those test statistics is not researched. Moreover, a little complex calculation might be necessary in some of those test statistics. Approach: In this … …Current Research in Biostatistics, Vol. 1, Issue 1 · 30 Jun 2010 · 14,098 accessesView PDF Cite
