Theoretical Estimation of Radon Emanation Coefficients for UO₂Particles Deposited on Surfaces of Uranium-bearing Wastes [PDF]

Journal of Nuclear Science and Technology, 2007
In nuclear fuel fabrication facilities, fine particles of UO2 deposit on the surfaces of walls, equipment, ventilation filters, etc. which may finally become uranium-bearing wastes when these items are removed or replaced. Radon is one progeny of uranium and emanates from those wastes.

Long term continuous radon monitoring in a seismically active area [PDF]

, 2015
We present the results of a long term, continuous radon monitoring experiment started in April 2010 in a seismically active area, affected during the 2010-2013 data acquisition time window by an intense micro seismic activity and by several small seismic

Construction and measurements of a vacuum-swing-adsorption radon-mitigation system [PDF]

, 2013
Long-lived alpha and beta emitters in the $^{222}$Rn decay chain on (and near) detector surfaces may be the limiting background in many experiments attempting to detect dark matter or neutrinoless double-beta decay, and in screening detectors.

Construction and Measurements of an Improved Vacuum-Swing-Adsorption Radon-Mitigation System

, 2015
In order to reduce backgrounds from radon-daughter plate-out onto detector surfaces, an ultra-low-radon cleanroom is being commissioned at the South Dakota School of Mines and Technology.

Fluid flow near reservoir lakes inferred from the spatial and temporal analysis of the electric potential [PDF]

, 2002
Electric self-potential (SP) variations have been monitored continuously from 1995 to 1998 at 14 points on a ridge separating the Roselend and La Gittaz reservoir lakes in the French Alps.

Identification of serum protein biomarkers for pre‐cancerous lesions associated with pancreatic ductal adenocarcinoma

Molecular Oncology, EarlyView.
This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...

A liquid xenon ionization chamber in an all-fluoropolymer vessel [PDF]

, 2006
A novel technique has been developed to build vessels for liquid xenon ionization detectors entirely out of ultra-clean fluoropolymer. We describe the advantages in terms of low radioactivity contamination, provide some details of the construction ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
