A cost-effective numerical model has been developed which employs hp-adaptive finite elements to construct velocity fields and Lagrangian particles to predict contaminant dispersion patterns. The adaptive finite element method is based on both mesh enrichment (h-adaptation) and spectral order incensement (p-adaptation). The use of Lagrangian particles permits rapid visualization and assessment ...

Local meteorological conditions including wind speed and turbulence significantly influence the dispersion of pollutant plumes, introducing severe difficulties in predicting its trajectory, potential evacuation sites, ultimately containment efforts. Ongoing developments estimating rapid contaminant include combined use local data along with plume-source localization identification via autonomou...

background anthracyclines are important components of many chemotherapeutic protocols. the present study aimed to evaluate the repolarization changes in electrocardiography (ecg) which may predict drug induced arrhythmia. materials and methods in this cross-sectional study, the recorded ecgs were assessed for qt dispersion (qtd), qt corrected dispersion (qtcd), t peak to tend dispersion (tped),...

An analytical method of determining the ionic diffusion transverse to the direction of flow in granular media is presented. The basic assumption that the frontal zone created by longitudinal dispersion is fully developed and stationary before the transverse diffusion can cause spreading is made to simplify the mathematical analysis. Solutions were obtained in terms of both a series of Bessel's ...
