Textural evidences indicate that pyrochlore and these minerals are produced by precipitation from hydrothermal fluids and the distribution of the different pyrochlore types suggests that the nature of the hydrothermal fluid controls their composition. Finally, the replacement of pyrochlore crystals by ...
The heat transfer fluid is initially heated by capturing solar thermal energy using the solar concentrator (PTC). The vaporized fluid then expands in the expander, generating work that is converted into electricity by an alternator (Alt). This electrical energy directly powers the hydraulic pump, ...
Given the above assumptions, the filtration coefficient can be expressed by the formula: k = Ql ∆hF (1) The filtration coefficient, which has a rate dimension, depends on both the properties of the filter medium and the physical properties of the filter fluid, such as density, temperature...
Cardiothoracic surgery then performed a redo sternotomy with an aortic valve replacement using a 27 mm Magna tissue valve four weeks after this third admission. The patient was treated post-operatively with aspirin and Plavix for 6 months, after which antiplatelet therapy may be discontinued ...
