The present invention relates to a pouch composition wherein the pouch is constructed from a water-soluble film and contains a composition comprising a C5-C20 polyol having at least two polar groups that are separated from each other by at least 5, carbon atoms. The method involves flowing growth media through a tube having adherent cells are adhered to the inner surface thereof and then contacting the growth media with an NO or O2 sensor to detect the concentration of NO or O2 in the growth media. The wireless communication device is configured to determine its location, to detect the arrival time of a first signal transmitted from the base station, and to calculate a line-of-sight delay corresponding to the LOS distance between the wireless communication device and the base station. The bracket and housing assembly enables the user to install the ceiling fan housing to the anchoring bracket without having to resort to using tools. Processing capacity may be thus calculated by mathematical analysis alone, based on a limited number of inputs regarding a real or theoretical computer system combination, in a fashion that replicates accurately, and can replace, actual physical testing or benchmarkings of systems.
