Sentence examples for initial abstraction from inspiring English sources

Intra-rater agreement was based on the re-abstraction of medical charts by abstractors from the same site at Time 2 (between July 2005 and February 2006) and comparing the re-abstracted data to data collected at the initial abstraction at Time 1 (between September 2003 and June 2005).

The natural resource conservation service curve number approach was used to estimate the initial abstraction of precipitation, infiltration, runoff, and estimate the threshold depth of precipitation.

The authors offer a model for the estimation of the runoff volume and the initial abstraction of each roof, and assess the physicochemical contamination of roof runoff.

Conversely, the flow temperature and initial abstraction ratio of rainfall have the lowest influence on tSHF (mean ˆTi is 0.11 and 0.12, respectively).

The tool enables the user to select among three antecedent moisture conditions and two values of the initial abstraction (Ia) parameter, and it has the option to include spatial variation in rainfall input.

We map out potential energy surfaces for large number of reactions, most notably, initial abstraction by O2 molecules, formation of peroxy- and hydroperoxyl adducts, unimolecular eliminations of HO2 and H2O as well as CC bond fissions.

Initial abstractions and average water losses during the rainfall runoff conversion processes were very important (runoff coefficients of 6% and runoff thresholds of 62 mm).

No correlation was found between initial abstractions (Ia) calculated from the basin characteristics and runoff thresholds (P0) empirically obtained, which create some doubts about the validity of Ia method for predicting floods in ephemeral streams.

Dry spells promoted crack formation in the expansive soil, which acted as preferential flow paths leading to high initial abstractions: average conditions for runoff to be generated included soil moisture content above 20%, rainfall above 70 mm, I30max above 60 mm h−1 and five continuous dry days at the most.

But, (I_{text{a}} = 0.2 times S) Q = frac{{(P - 0.2S ^{2} }}{P + 0.8S},{text{whenn }}P > 0. 2 {text{S}},{text{ otherwise }}Q (2) S = frac{25,400}{text{CN}} - 254, (3) where Q represents the run-off (mm), P stands for rainfall (mm), S stands for potential maximum retention (mm) and I a denotes the initial abstractions (due to infiltration, evaporation, interception).

To minimize the potential for recall and artificial inflation of observed agreement, all data abstracted during Time 1 (initial chart abstraction) were returned to the research centre upon their completion, and chart abstractors were not granted access to their original responses at Time 2 (chart re-abstraction).
