Impact of oxygen content in powders on the morphology of the laser molten tracks in preparation for additive manufacturing of silicon
Patrik Willi Hoffmann, Lucas Güniat, Marc Leparoux
Powder additive pulsed Nd:YAG laser (wavelength 1064 nm), with the aim of preparing AM of such material. The influence of oxygen content in the initial silicon powders on the continuous tracks morphology was investigated. It was found that the initial oxyg ...
ELSEVIER2020Oxygen availability in a HAPE-positive and a HAPE-negative woman before and during a visit to 3480 meters
Background: Testing the hypoxic ventilatory response (HVR) at low-altitude helps to detect those who do not hyperventilate appropriately in hypoxia but might not necessarily predict the HVR and the risk to develop acute mountain sickness (AMS) at high alti ...
