Abstract We report the discovery of a one magnitude increase in optical brightness 59.63 minutes orbital period AM CVn binary SDSS J113732.32+405458.3. Public g , r and i band data from Zwicky Transient Facility exhibit subsequent decline over 300 days period, while few points commissioning show that peak was likely seen. Such an outburst is due to change state accretion disk, making this longe...

The issue of laboratory critical value (CV) reporting has gained importance in the recent times due to national focus on patient safety. Critical notification (CVN) become an essential part accreditation procedures for medical laboratories, including universally accepted International Organization Standardization (ISO) 15189: 2012. Our study aimedto analyze data hematology and biochemistry sect...

The Gurson–Tvergaard–Needleman (GTN) damage model is widely used to predict ductile failure initiation and propagation. However, the material-dependent parameters can show a significant spread when determined for same steel grade material. Different calibration procedures optimisation processes cause variation in obtained parameter values. Furthermore, there no clear consensus on which require ...

An analysis of a comprehensive survey of radio luminosities for RS CVn binary systems is given. A comparison is made between the rotation-activity correlations found using the usual semi-empirical Rossby number and a Rossby number deduced from detailed convection zone models. The use of a non-empirically derived Rossby number does not signiicantly improve the rotation-activity correlation. Alth...

Charpy V-notch impact testing is widely used in the toughness assessment of large forged components, e.g. the pressure vessel for pressurised water reactors m). At low temperature, A508 C1.3 nuclear pressure vessel steel fails by cleavage fracture. The results reported here are part of both an experimental program and numerical investigations which aim at the establishment of a non-empirical re...
