in this study, the effect of chemical modification of wood flour on the mechanical properties of polypropylene based composites was investigated using by dynamic mechanic thermal analysis. to meet this objective, the wood flour treated with chemical components including alkaline, acetic acid and benzoyl chloride, and then the chemically treated fibers were compounded with polypropylene at 180 °...
Abstract. For earthquake-resistant design, structural degradation is considered using traditional strength modification factors, which are obtained via the ratio of nonlinear seismic response degrading and non-degrading single-degree-of-freedom (SDOF) systems. In this paper, with aim to avoid compute a methodology based on probabilistic hazard analyses (PSHAs), proposed in order obtain factors ...
We try to understand recent data on proton-proton and deuteron-gold collisions at RHIC, employing a modified parton model approach. 1 Interesting data from RHIC The nuclear modification factor R = (dNAA/d pt) / (Ncoll dNpp/d pt) shows interesting features: For AuAu, it is much smaller than one for central collisions, whereas for d-Au, it is bigger than one for central collisions. With decreasin...
BACKGROUND Diverse growth factors secreted from human adipocyte-derived stem cells (hASCs) that support or manage adjacent cells have been studied for therapeutic potentials to a variety of pathological models. However, senescent growth arrest in hASCs during in vitro culture and subsequent defective differentiation potential, have been technical barriers to further genetic modification of hASC...
