The mass transport properties of the hollow fibre membrane modules were measured with single gases, CH4 and CO2, and their mixtures, referred to as molar ratio, CH4 CO2 = 50 50, CH4 CO2 = 70 30 and CH4 CO2 = 5 95.
An ideal experiment would be one where the retinotopic and orientation maps are measured with single cell resolution along with a reconstruction of the X retinal ganglion cell mosaic from the contra-lateral eye in a region representing the same location of visual space.
Pain and fatigue were measured with single items using VAS scales [ 25, 26].
At the time, mental health was measured with single item questions.
Both were measured with single items, on a five-point Likert scale.
Dental anxiety has often been measured with single questions in previous research and the DAQ has shown good validity [ 31].
Biomarkers were measured with single or multiplexed immunoassays using standard ELISA, Luminex 200 (Luminex, Austin, TX, USA), MSD SECTOR Imager 6000 (Meso Scale Discovery, Gaithersburg, MD, USA), or Astute140™ Meter (Astute Medical, San Diego, CA, USA) platforms.
Hepatic fat content was measured with single volume magnetic resonance spectroscopy (MRS) in an 8 ml volume in the posterior right lobe of the liver as described previously (16).
Third, the vast majority of studies used a standardized experimental protocol, namely the oral administration of dexamethasone to depressed participants and non-depressed controls at or around 11 p.m., and cortisol levels were measured with single or repeated blood draws at various times during the subsequent day.
The indoor and outdoor PM concentrations were measured with single-stage inertial HIs and 37-mm Teflon filters for PM10 and PM2.5.
