Buda Thermal Karst system, Hungary. The pilot area has high geothermal potential characterized by prominent thermal anomalies, such as springs and spas which tap the Triassic carbonate aquifers. Therefore, numerical simulations were carried out to examine temperature field flow pattern considering three successive heat transport mechanisms: conduction, forced mixed convection in order highlight...

The thermal conductivity of superconducting MgB 2 was studied in both the superconducting and normal state region. The latter is almost equally determined by the electronic-and the lattice thermal conductivity. In the superconducting state, however, the lattice thermal conductivity is larger. The electronic thermal conductivity below T c was derived from the experimental data considering the Ba...

The optical characterization is reported of a new fluid consisting of single wall carbon nanohorns and ethylene glycol for solar energy applications. Carbon nanohorns play a significant role in enhancing sunlight absorption with respect to the pure base fluid. The obtained results are compared with those obtained for fluids suspending more conventional carbon forms, i.e. carbon-black particles....

Two-photon excitation fluorescence microscopy allows in vivo high-resolution imaging of human skin structure and biochemistry with a penetration depth over 100 microm. The major damage mechanism during two-photon skin imaging is associated with the formation of cavitation at the epidermal-dermal junction, which results in thermal mechanical damage of the tissue. In this report, we verify that t...

BACKGROUND Percutaneous vertebroplasty by injecting PMMA bone cement into the fractured vertebrae has been widely accepted in treatment of spinal compression fracture. However, the exothermic polymerization of bone cement may cause osseous or neural tissue injury. This study is thus designed to evaluate the potential risk of thermal damage in percutaneous vertebroplasty. METHOD Twelve porcine...

Resurfacing arthroplasty of the hip is being used increasingly as an alternative to total hip replacement, especially for young active patients. There is concern about necrosis of the femoral head after resurfacing which can result in fracture and loosening. Most systems use a cemented femoral component, with the potential for thermal necrosis of the cancellous bone of the reamed femoral head. ...

We report melting points and other thermal properties of several semiconducting and metallic elements as they are modelled by different empirical interatomic potential models, including Stillinger-Weber (SW), embedded-atommethod (EAM), Finnis-Sinclair (FS) and modified-embedded-atom-method (MEAM). The state-of-the-art free energy methods are used to determine the melting points of these models ...
