two-layer metallic sheets have wide applications in aerospace, marine, automotive and domestic industries due to their superlative characteristics. in this paper, the formability of two-layer sheet is investigated through analytical, experimental and numerical approaches. an analytical model is developed based on marciniak-kuczynski method associated hill’s non-quadratic yield criterion. formin...

Introduction: Some segments of the human genome exhibit polymorphism due to a variable number of tandem repeats (VNTR). The enzymatic amplification of VNTR loci can allow for rapid analysis and discrimination of closely sized alleles. We report a PCR-based method for analysis of the highly polymorphic Stl4 VNTR. Source and Description: The Stl4-1 probe is a 3 kb EcoRI fragment cloned from human...

Hepatocyte growth factor activator inhibitor-1 (HAI-1), encoded by the serine protease inhibitor Kunitz type 1 (SPINT1) gene, is a membrane-associated proteinase inhibitor that potently inhibits a variety of serine proteinases, including those that are membrane bound. Although HAI-1/SPINT1 is widely expressed by epithelial cells and cancer cells, its functional role is still unclear, particular...
