Altitude-related cough [PDF]

open access: yesCough, 2013
Altitude-related cough is a troublesome condition of uncertain aetiology that affects many visitors to high altitude. The traditionally held belief that it was due solely to the inspiration of cold, dry air was refuted by observations and experiments in long duration hypobaric chamber studies.

Greek Protected Designation of Origin Xinomavro Wines: A Deep Dive into Their Chemical Composition and Geographical Origin by Using Ultra High Performance Liquid Chromatography–Trapped Ion Mobility Spectrometry–Quadrupole Time of Flight–Mass Spectrometry

open access: yesAnalysis &Sensing, EarlyView.
Greek protected designation of origin Xinomavro wines are analyzed with ultra high performance liquid chromatography–trapped ion mobility spectrometry–quadrupole time of flight‐mass spectrometry (UHPLC‐TIMS‐QTOF‐MS). Both target and not‐target screening approaches are employed, leading to the identification and quantification of several polyphenols and

NASA aviation safety reporting system [PDF]

open access: yes
An analytical study of reports relating to cockpit altitude alert systems was performed. A recent change in the Federal Air Regulation permits the system to be modified so that the alerting signal approaching altitude has only a visual component; the ...

System for indicating fuel-efficient aircraft altitude [PDF]

open access: yes, 1984
A method and apparatus are provided for indicating the altitude at which an aircraft should fly so the W/d ratio (weight of the aircraft divided by the density of air) more closely approaches the optimum W/d for the aircraft.
