Watershed models are powerful tools for simulating the effect of watershed processes and management on soil and water resources. However, no comprehensive guidance is available to facilitate model evaluation in terms of the accuracy of simulated data compared to measured flow and constituent values. Thus, the objectives of this research were to: (1) determine recommended model evaluation techni...

Of the eight desirable attributes of a standardized method given in KSA-SM-3, three are the focus of this article: resemblance of the untreated control data, repeatability of the response of interest across multiple tests, and reproducibility of the response across multiple laboratories. These attributes can be assessed by considering three random effects on the response: among-carrier differen...

BACKGROUND Computerized mathematical models describing absolute and relative individual growth during puberty in both cm and standard deviation (SD)-scores are lacking. The present study aimed to fill this gap, by applying the QEPS-model that delineates mathematically the specific pubertal functions of the total growth curve. METHODS Study population used was the individual growth curves of t...
