3D MODELLING OF A TUNNEL RE-EXCAVATION IN SOFT GROUND

3D Modelling of a Tunnel Re-excavation in Soft Ground

The construction of the shallow tunnel at Brezno started using the Pre-Vault Method.The tunnel excavation, in complicated geological conditions, led to many difficulties which finally resulted in a collapse, when a significant part of the temporary tunnel lining collapsed.Various options for re-excavating the tunnel were evaluated prior to further

Flow Stress Behavior and Microstructure Evolution of Austenitic Stainless Steel with Low Copper Content during Hot Compression Deformation

In order to study the Famil-E microstructure evolution and flow stress behavior of as cast antibacterial austenitic stainless steel containing 1.52 wt.% copper, Gleeble 3800 was used for thermal compression simulation test.Through OM and EBSD analysis, it is found that the dynamic recrystallization mechanism of thermal deformation is mainly discont

Interaction of Arylidenechromanone/Flavanone Derivatives with Biological Macromolecules Studied as Human Serum Albumin Binding, Cytotoxic Effect, Biocompatibility Towards Red Blood Cells

The aim of this study was to determine the cytotoxic effect of 3-arylidenechromanone (1) and 3-arylideneflavanone (2) on HL-60 and NALM-6 cell lines (two human leukemia cell lines) and a WM-115 melanoma cell line.Both compounds exhibited high cytotoxic activity with higher cytotoxicity exerted by compound 2, for which IC50 values below Wrinkle Seru
