The Steam-Jet Aerosol Collector-long Pathlength Absorbance Spectroscopy (SJAC-LPAS), an on-line continuous instrument for mobile measurements of spatial distribution of water-soluble hexavalent and trivalent chromium in ambient aerosols, has been developed and is presented here.
As Rev. Williams' life unravels, education has become a continuous instrument of growth: from undergraduate studies at Eastern Michigan University and on to graduate studies.
Exploratory analyses were conducted comparing outcomes between the ED and UC groups using chi-square tests to compare categorical variables and t tests to compare continuous instrument scores.
In the hours surrounding these samples, group-level measurements of particle concentrations also were collected using several continuous instruments installed on two portable carts.
We measured PM2.5 and PM10 at specified locations along a fixed route of 25 stops using continuous instruments, during multiple weekday mornings and afternoons, in both seasons, at a range of elevations and distances from ETSW.
Second, concentrations are typically measured at short intervals using continuous instruments which, with good quality-control efforts, can provide information about short-term peak exposures associated with adverse acute health effects [ 23].
The Behavior and Sensory Interests Questionnaire (BSIQ) is a newly designed, continuous dimensional instrument that comprehensively assesses the type, frequency, intensity, age of onset, and duration of these behaviors.
Attached to the other head of the steam distillation continuous extraction instrument, diethyl ether (35 mL) was used as the solvent in a 500 mL round-bottom flask, and the flask was heated at 42°C by a water bath pot, HH-2 (Jiangsu, China).
The linearity standards were reanalyzed repeatedly during the analytical run to ensure continuous correct instrument response.
Electrical flow/pre-polarization conductance was measured with Motoyama's "single square voltage pulse" method using a continuous recording instrument kindly provided by California Institute for Human Science.
We recorded optical signals from the left prefrontal cortex in 10 right-handed participants with a continuous-wave instrument (DYNOT, NIRx, Brooklyn, NY).
