In recent years, electrical and I&C components in nuclear power plants (NPPs) were replaced by software-based components. Due to the increased number of software-based systems also the threat of malevolent interferences and cyber-attacks on NPPs has

In this paper we present an approach for the evaluation and assessment of the impact of software failures in software-based I&C systems of NPPs. The proposed two-step approach includes at the first step the identification of software failure modes on

The reliability of the auxiliary power supply of a nuclear power plant (NPP) is of high importance for safe operation. The loss of the electrical power supply is one of the major contributions to the calculated core damage frequency in probabilistic

This report deals with an enzootic due to Salmonella Typhimurium in two free living Eurasian siskins (Spinus spinus Linnaeus, 1758). Other birds in the vicinity of the siskins were not affected. Clinical signs consisted of non-specific symptoms such

Objective Plasticity of hematopoietic stem cells (HSC) has gained major interest in stem cell research. In order to investigate whether HSC may differentiate into mesenchymal stem cells (MSC), we assessed chimerism in peripheral blood (PB), mononucle
