Sensitivity and uncertainty analysis for the tritium breeding ratio of a DEMO fusion reactor with a helium cooled pebble bed blanket

open access: yesEPJ Web of Conferences, 2017
An uncertainty analysis was performed for the tritium breeding ratio (TBR) of a fusion power plant of the European DEMO type using the MCSEN patch to the MCNP Monte Carlo code.

Design and simulation of a blanket module with high efficiency cooling system of tokamak focused on DEMO reactor

open access: yesNuclear Engineering and Technology, 2020
In this study, the neutronic calculation to obtain tritium breeding ratio (TBR) in a deuterium-tritium (D-T) fusion power reactor using Monte Carlo MCNPX is done. In addition, by using COMSOL software, an efficient cooling system is designed.

The effect of altered pH growth conditions on the production, composition, and proteomes of Helicobacter pylori outer membrane vesicles

open access: yesPROTEOMICS, Volume 24, Issue 11, June 2024.
Abstract Gram‐negative bacteria release outer membrane vesicles (OMVs) that contain cargo derived from their parent bacteria. Helicobacter pylori is a Gram‐negative human pathogen that produces urease to increase the pH of the surrounding environment to facilitate colonization of the gastric mucosa.

Entangling a nanomechanical resonator with a microwave field [PDF]

open access: yes, 2007
We show how the coherent oscillations of a nanomechanical resonator can be entangled with a microwave cavity in the form of a superconducting coplanar resonator.

Structural characterization of the Sel1‐like repeat protein LceB from Legionella pneumophila

open access: yesProtein Science, Volume 33, Issue 3, March 2024.
Abstract Legionella are freshwater Gram‐negative bacteria that in their normal environment infect protozoa. However, this adaptation also allows Legionella to infect human alveolar macrophages and cause pneumonia. Central to Legionella pathogenesis are more than 330 secreted effectors, of which there are nine core effectors that are conserved in all ...

Quantum switch for single-photon transport in a coupled superconducting transmission line resonator array

open access: yes, 2009
We propose and study an approach to realize quantum switch for single-photon transport in a coupled superconducting transmission line resonator (TLR) array with one controllable hopping interaction.

Effect of HIP at 1000–1200 °C on microstructure and properties of extruded Be-Ti composites

open access: yesNuclear Materials and Energy, 2022
Solid titanium beryllide blocks will be used for neutron multiplication in the helium-cooled pebble bed (HCPB) blanket concept of EU DEMO. A combination of hot extrusion of Be-Ti powders and subsequent hot isostatic pressing (HIP) of the obtained Be-Ti ...
