Municipal solid waste (MSW) is a domestic energy resource with the potential to provide a significant amount of energy to meet US liquid fuel requirements. MSW is defined as household waste, commercial solid waste, nonhazardous sludge, conditionally exempt, small quantity hazardous waste, and industrial solid waste. It includes food waste, residential(More)
(U-Th)/He Dating of Single Zircon and Apatite Crystals — A New Tool for Dating Terrestrial Impact Structures [#2041] The low temperature (U-Th)/He technique has been utilized to date individual crystals from the Manicouagan, Lake Saint Martin, and Bosumtwi impact structures. New (U-Th)/He zircon ages are in agreement with ages obtained via other dating(More)
The effects of changes in stimulus interval and the infusion of isoprenaline upon myocardial depolarization and repolarization times have been determined using the unipolar ventricular evoked potential. An isolated perfused rabbit heart was the experimental vehicle and the stimulus-to-R wave (St-R) and R wave-to-end (R-E) of complex time intervals were used(More)
With the current interest in bipolar stimulation, there is a need for greater understanding of the electrical contributions of the two electrodes in this type of pacing. This has been investigated using a specially designed cell in which an electrode under test was immersed in a buffered saline solution (pH 7.42) at 37-38 degrees C. Four electrode types(More)
Investigation of the unipolar properties of the paced-evoked response requires special measures to eliminate the post-stimulus potential, and this in turn requires a knowledge of the properties of the electrode-tissue interface which is not supplied by any single source in the literature. We have therefore drawn together published information and some of(More)
