Effect of incineration, co‐incineration and combustion on TSE hazards in category 1 animal by‐products

EFSA Journal, Volume 23, Issue 5, May 2025.
Abstract The European Commission requested EFSA to assess the effect of incineration, co‐incineration and combustion of Category 1 animal by‐products (ABP) on the BSE/TSE hazards in ash resulting from these treatments. The presence of residual TSE hazards is assessed by detection of prion infectivity or seeding activity.

Experimental Research on an Afterburner System Fueled with Hydrogen–Methane Mixtures

Inventions
A new afterburner installation is proposed, fueled with pure hydrogen (100%H2) or hydrogen–methane mixtures (60% H2 + 40% CH4, 80% H2 + 20% CH4) for use in cogeneration applications.

The Heisenberg‐RIXS instrument at the European XFEL

Journal of Synchrotron Radiation, Volume 32, Issue 1, Page 29-45, January 2025.
The aim of this work is to present Heisenberg RIXS at the European XFEL, the first high‐resolution soft X‐ray instrument enabling time‐resolved resonant inelastic X‐ray scattering close to the transform limit from solid and liquid‐jet samples. The optical design, mechanical layout and performance are described in detail and discussed in a broader ...

Three-fluid Hydrodynamics-based Event Simulator Extended by UrQMD final State interactions (THESEUS) for FAIR-NICA-SPSBES/RHIC energies

EPJ Web of Conferences, 2018
We present a new event generator based on the three-fluid hydrodynamics (3FH) approach, followed by a particlization at the hydrodynamic decoupling surface and a subsequent UrQMD afterburner stage based on the microscopic UrQMD transport model that ...

Obtaining high degree of circular polarization at x-ray free electron lasers via a reverse undulator taper

Physical Review Special Topics. Accelerators and Beams, 2013
Baseline design of a typical x-ray free electron laser (FEL) undulator assumes a planar configuration which results in a linear polarization of the FEL radiation. However, many experiments at x-ray FEL user facilities would profit from using a circularly

Simulating Afterburn with LLNL Hydrocodes [PDF]

, 2004
Presented here is a working methodology for adapting a Lawrence Livermore National Laboratory (LLNL) developed hydrocode, ALE3D, to simulate weapon damage effects when afterburn is a consideration in the blast propagation. Experiments have shown that afterburn is of great consequence in enclosed environments (i.e.
