When the open section is to leeward, the transient solutions confirm that the gas dispersion from the covered section takes place through an intermittent "vortex and purging" release, governed by the interactions between the large structures in the vicinity of the open side.
It is determined that primary and secondary laminar-flame instabilities associated with the coupling between acoustic waves and the rate of chemical heat release govern the evolution of both the flame-speed and the upstream flow field in the TC combustor, as was found in earlier experiments and predicted theoretically for downward flame propagation in tubes.
Last month, a vote by the Screen Actors Guild let lapse an agreement dating back to 1939, when those films were released, governing the relationship between agents and actors.
The other set of rules released govern the program for states that are on board with the new regime.
Regulation of the colicin operon is likely to be essential in determining the outcome of colicin-mediated competition, as the conditions under which colicin is produced and released govern the community dynamics.
The F.A.A. is supposed to release rules governing the commercial use of drones by mid-2014.
The four-time overall champion is among the 65 racers who appear on the start list for training that was released by governing body FIS late Wednesday.
Although then-Attorney General Alberto Gonzales released guidelines governing the FBI's use of confidential informants in 2006, there is no congressional oversight of these activities.
With this interesting combination of tunable mechanical properties and degradation, the PEGDA-PEI hydrogel system display a dual-mode drug release kinetics in which the drug release was governed by swelling-controlled and degradation-controlled mechanisms in sequence, which demonstrates the potential for drug delivery applications.
More importantly, the Eu3+/Gd3+-doped HAp nanorods show a high drug adsorption capacity and sustained drug release using ibuprofen as a model drug, and the drug release is governed by a diffusion process.
It is well acknowledged that the Higuchi model (C = K·t 1/2) can well describe the kinetics of drug release from carrier materials [49 51], with a linear relationship between the cumulative amount of the released drug (C) and the square root of time (t 1/2), and that the drug release is governed by a diffusion process.
