The purpose of this study was to evaluate the large-scale structure, and hence available reserves, of the Lower Cretaceous Luscar Formation near Mountain Park, in the Foothills of Alberta. Coal resource evaluation clearly requires information on the mineable tonnages, as well as the grade, of the coal strata. In open pit mining, the volume of coal economically extracted from a seam is directly ...

in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
