University of Kentucky Measurements of Wind, Temperature, Pressure and Humidity in Support of LAPSE-RATE Using Multisite Fixed-Wing and Rotorcraft Unmanned Aerial Systems
In July 2018, unmanned aerial systems (UASs) were deployed to measure the properties of the lower atmosphere within the San Luis Valley, an elevated valley in Colorado, USA, as part of the Lower Atmospheric Profiling Studies at Elevation – a Remotely-piloted Aircraft Team Experiment (LAPSE-RATE). Measurement objectives included detailing boundary layer transition, canyon cold-air drainage and convection initiation within the valley. Details of the contribution to LAPSE-RATE made by the University of Kentucky are provided here, which include measurements by seven different fixed-wing and rotorcraft UASs totaling over 178 flights with validated data. The data from these coordinated UAS flights consist of thermodynamic and kinematic variables (air temperature, humidity, pressure, wind speed and direction) and include vertical profiles up to 900 m above the ground level and horizontal transects up to 1500 m in length. These measurements have been quality controlled and are openly available in the Zenodo LAPSE-RATE community data repository (https://zenodo.org/communities/lapse-rate/, last access: 23 July 2020), with the University of Kentucky data available at https://doi.org/10.5281/zenodo.3701845 (Bailey et al., 2020)
Different kalemia in abdominal trauma
Unlike previous reports, in 123 patients with abdominal injury or surgery significant and persistent hypokalemia was observed only after traumatic or surgical injuries of the liver. On the contrary, in all other extrahepatic abdominal trauma or operations kalemia was normal. This discrepancy may be related to the much greater abundance, in comparison with other abdominal organs, of adrenergic endings present in the liver. Trauma to or surgery of the liver stimulates such fibers, which locally release proportionally large amounts of norepinephrine. The consequent stimulation of beta-adrenergic receptors enhances the transfer of potassium from the blood into the cells, even if the affinity of norepinephrine for such receptors is less than that of epinephrine. The frequent finding of kaliuria at the upper normal levels may suggest an accessory role of aldosterone in causing and maintaining this hypokalemia
