Due to this unbalanced sampling design, a homogeneous dispersion of the values in the groups defined by the levels of the independent variables is a precondition to test for differences in location of the groups [8, 9]. With the PERMDISP test (9999 permutations), the data were tested for ...
Vehicles that fail need to be repaired and retested within 60 calendar days from the date of the initial test. Click here for information on failing the Connecticut Emissions Test. Your vehicle may be turned away... Your vehicle can be turned away and not tested for various reasons; to ...
Ponds that do not receive fresh froth treatment tailings, but rather older tailings, tailings transferred from other ponds, CT and a higher percentage of coarser tailings are expected to contain less residual diluent and emit less fugitive VOCs. Lower VOC emissions may also be due to aerobic ...
WLTC: World Harmonized Light Vehicle Test Cycle; AK: adenylate kinase; LDH: lactate dehydrogenase. Prior to the exposure to complete emissions and control air (time point T0), we collected a medium and measured the TEER to obtain data from cells which were neither affected by handling nor ...
compared with lakes, wetlands and rice paddies1(P < 0.001, Wilcoxon rank-sum test; Fig.4b). We attribute these lowEMestimates to the fundamentally open nature of running waters, in which external inputs not only account for a large fraction of carbon gases evaded to the atmosphere8but...
Second, we took samples of organic matter aggregates (floating filamentous algal and/or organic matter debris) associated with dense stands of macroalgae (Supplementary Fig.2a,b) to test whether there were potential non-sedimentary CH4sources. Anaerobic microsites in dense stands of submerged macrophy...
The Friedman test \iaS performed on the mean slopes for each subject, and a significant difference was not found between any of the three PTC conditions. A difference did not exist between the bilateral and unilateral groups as determined by the Kolmogorov-Smirnov two-sample test. Repeatability ...
Most interventions to date have targeted anaesthesia or pathology test ordering in hospital settings. Due to the diverse study outcomes and consequent inability to pool the results, this review is descriptive only, limiting our ability to conclude the effectiveness of interventions. Multiple BCTs were ...

The p-value results from a statistical test that compares the performance of a machine learning model using all masses as input to the performance of a model using all but one mass as input. The difference between these two cases is tested using a corrected paired t-test46. The t-test ...
