To prevent oxygen contamination, additive manufacturing (AM) techniques normally operate in an inert gas chamber (GC). An alternative method, useful for large builds and components repair, is the application of localised shielding gas (LSG).

The Measurement of Neutron Contamination in High Energy X-Ray Radiotherapy Using a He-3 Gas Dosimeter [PDF]
Introduction: Neutron contamination is likely caused by the collision of high-energy photon interactions (γ, ṉ) with heavy metals used in the construction of the accelerator.

Advanced Head Disk Interface System Assisted by Gas PFPE Lubrication
An advanced head disk interface (HDI) system assisted by gas perfluoropolyether (PFPE) lubrication is discussed in this paper. It is known that lubricant spins off at a high rotation speed and high temperature.

Luminescence quenching of the triplet excimer state by air traces in gaseous argon [PDF]
While developing a liquid argon detector for dark matter searches we investigate the influence of air contamination on the VUV scintillation yield in gaseous argon at atmospheric pressure. We determine with a radioactive alpha-source the photon yield for

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Brazing retort manifold design concept may minimize air contamination and enhance uniform gas flow [PDF]
Brazing retort manifold minimizes air contamination, prevents gas entrapment during purging, and provides uniform gas flow into the retort bell. The manifold is easily cleaned and turbulence within the bell is minimized because all manifold construction ...

Systemic dysregulation of apolipoproteins in amyotrophic lateral sclerosis serum
Amyotrophic lateral sclerosis (ALS) is a fatal disease that damages motor neurons. This study found that people with ALS show significant changes in blood fats and the proteins that carry them. Several apolipoproteins were higher, lipid balances were altered, and normal protein–lipid relationships were disrupted.

Using radon-222 in soil gas as an indicator of subsurface contamination by non-aqueous phase-liquids (NAPLs) [PDF]
The dependence of the soil gas radon concentration on ground contamination by non-aqueous phase-liquids (NAPLs) was studied. Subsurface NAPL contamination is known as one of the major problems concerning the clean-up of polluted industrial sites.
