Intriguing experimental results raised the question about the fundamental mechanisms governing the electron-hole coupling induced bipolar thermal conduction in semiconductors. Our combined theoretical analysis and experimental measurements show that in semiconductors bipolar thermal transport is in general a "conductivity-limiting" phenomenon, and it is thus controlled by the carrier mobility r...

Evidence is presented for neutrons emanating from partially deuterated titanium foils (TiDx) subjected to non-equilibrium conditions (charged particle results appear in a separate paper in this proceedings). Two types of deuteriding and varied currents were employed to produce the non-equilibrium conditions within the foils, and emissions lasted over long durations. Experiments were conducted i...

Miocene through Pleistocene sediments on the New Jersey continental slope (Ocean Drilling Program Site 1073) are undercompacted (porosity between 40 and 65%) to 640 meters below the sea floor, and this is interpreted to record fluid pressures that reach 95% of the lithostatic stress. A two-dimensional model, where rapid Pleistocene sedimentation loads permeable sandy silt of Miocene age, succes...

Site U1324 is the westernmost site drilled in the Ursa basin by Expedition 308. Of the three sites in the Ursa Basin, Site U1324 has the thickest sediment loading above the permeable Blue Unit. The principal objectives of drilling Site U1324 were to document rock physical properties at the location of maximal overburden in the Ursa Basin, measure in-situ formation temperature and pressure, docu...

complaint open to increasingly a.lert patients for which, or for whom, the onus of management in the code of practice is being placed on the nurse in charge of the ward and her record book. I estimate that there are already 11 or 12 channels of complaint open to the customers. By all means let us establish machinery that allows free conument and honest answer, but let it be a system that will b...

After excavation, insitu stress conditions are changed which lead deformation due to the concentration. For stability in excavated tunnel profile, appropriate support system is essential. To recommend system, site specific data used from Higher Himalayan Region of Nepal. Study focused on 3 m and 6 size inverted D Shaped with three different overburden thickness. analysis system: Empirical metho...
