Applications of an improved estimator of the constitutive relation error to plasticity problems
Gallimard, L.,Ladeveze, P.,Pelle, J.P. Techno-Press 2002 Structural Engineering and Mechanics, An Int'l Jou Vol.14 No.4
This paper presents several applications of an improved estimator of the constitutive relation error (CRE) for plasticity problems. The cumulative aspect of the CRE estimator with respect to time is analyzed and we propose a first analysis of the local effectivity indexes of the CRE estimator in plasticity.

Wound dressings are based on the creation of ideal environments for cell mobility, gas exchanges and to promote tissue healing and regeneration, besides controlling bacterial proliferation. Electrospinning is a simple, cheap and common technique used for such purposes and Ecovio®, a polymeric blend based on biocompatible polymers (poly(butylene adipate-co-terephthalate) (PBAT) and poly(lactic acid) (PLA)), is a good example of polymer with unique properties for wound dressing materials development. To ensure antimicrobial properties, Job’s tears (Coix lacrymajobi) extract was incorporated into the material. The obtained fiber mats were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), X-ray diffractometry (DRX), optical microscopy (OM), and microbiological analysis. The interaction among the compounds of the extract and the polymeric matrix was inferred by the increase in the crystallinity degree and thermal stability of the fibers/extract. Also, a decrease in the diameter, roughness, and fiber homogeneity was observed. It happened due to the presence of extract in the fibers. Microbiological analysis (antimicrobial activity against S. aureus) indicated the effectiveness of the fibers/extract in preventing this bacteria growth, demonstrating the potential of this material for wound dressing purposes.
Foreign Influences on American Culture in the 20Th Century
( Richard Pells ) 서울대학교 미국학연구소 2011 미국학 Vol.34 No.2
The Americanization of the world is a myth. America`s cultural relationships with other countries are not one-sided. Instead, the relationship is reciprocal. Americans have always depended on foreign ideas, talent, immigrants, and refugees to contribute to developments in American painting, architecture, music, and films. As a result, America`s culture as been globally popular not because it turned the world into a replica of the United States, but because the United States is a replica of the world.

Preconditioning of the myocardium rapidly induces a number of transcription factors, which are likely to be responsible for a cascade of transcriptional changes underlying the development of delayed adaptation. Identifying these changes provides in-sight into the molecular pathways elicited by delayed adaptation. Genes up-regulated in rabbit myocardium in vivo by ischaemic preconditioning following reperfusion for 2 h, 4 h and 6 h post- treatment were identified by representational dif-ference analysis of cDNA (cDNA. RDA). The area of the left ventricle rendered ischaemic by precon-ditioning or the equivalent area of sham-treated animals was isolated and cDNA.RDA performed. Three novel genes and six genes with known function where identified, including the TGFβ receptor interacting protein 1, the α isoform of the A subunit of PP2 and the cap binding protein NCBP1. To determine whether expression of these genes correlated with preconditioning per se, expression was measured in myocardium after both ischaemic as well as heat shock induced preconditioning following 2 h, 4 h, and 6 h reperfusion. These genes were induced in rabbit myocardium in vivo by both ischaemia and heat shock, consistent with a fundamental role in the development of delayed adaptation. The well described role of PP2 in modulating the mitogen-activated protein kinase pathway and promoting cell survival is consistent with our previous work, which identified the reper-fusion injury salvage kinase pathway in mediating the protective effects of ischaemic preconditioning. Expression of Trip1 and Ncbp1 also implicates TGFβ signalling pathways and RNA processing and transport in delayed adaptation to stress in the myocardium.
