1 Inspiratory Oxygen Fraction (FiO2) and oxygen partial pressure (paO2) depending on the oxygen flow in different face masks - Efficiency and cost analysis of two different oxygen face masks. 2  Evaluation of two oxygen face masks with special regard to inspiratory oxygen fraction (FiO2) for emergency use in rescue helicopters.
The X-Files review â reboot gets off to a stuttering start then gains momentum. The first episode of the showâs return fails to drag it into the present â but the third episode is a spectacular deconstruction of not only the show but its genre. Brian Moylan.

More on that here. Note that if we want to delete all files older than X we would use-lt. ie, the timestamp of the file is older than 15 minutes ago. If we want to delete files newer than X we would use-gt. ie, the timestamp of the file is newer than 15 minutes ago.X, in our case, is the time now minus 15 minutes.owershell: delete files older than X. It really is that easy. Get-ChildItem $env:temp /myfiles | where { $_ .Lastwritetime-lt (date).addminutes(- 15)} | remove-item. E verybody has needed the 'delete files older than X' script.
