Epstein-Barr virus binding to virus-carrying cell lines is enhanced in the presence of C3 and C3d

The relationship between the receptors for the Epstein-Barr virus (EBV) and the C3d fragment of complement was investigated at the molecular level. In the presence of cell-bound C3, virus binding was enhanced in EBV genome-carrying lines. An identical effect could be elicited by C3d at one-quarter the weight amount; C3b and methylamine-treated C3 had no effect on virus binding. The minimum concent

Dymola and Modelica_EmbeddedSystems in Teaching-Experiences from a Project Course

This contribution presents experiences from a master level project course where a Modelica-based tool, Dymola, supporting embedded control system design has been used. In a recent initiative, the Modelica language has been enhanced to support modeling of embedded systems and code generation targeted at micro processors. Then new specification is sup-ported by, e.g., Dymola and enables wide range o

Hazard Analysis of Collision Avoidance System using STPA

As our society becomes more and more dependent on IT systems, failures of these systems can harm more and more people and organizations both public and private. Diligently performing risk and hazard analysis helps to minimize the societal harms of IT system failures. In this paper we present experiences gained by applying the System Theoretic Process Analysis (STPA) method for hazard analysis on a

Radiation dose optimization in CT planning of corrective scoliosis surgery. A phantom study.

The aim of the study was to explore the possibility of obtaining a helical CT scan of a long segment of vertebral column, optimally reduce the radiation dose, compare the radiation dose of the low dose helical CT with that of some of the CT protocols used in clinical practice and finally assess the impact of such a dose reduction on the image quality. A chest phantom was examined with a 16-slice C
