Phonon Emission and Absorption Experiments in the Quantum-Hall Regime
The absorption and emission of phonons by a two-dimensional electron gas (2DEG) has been studied in a quantizing magnetic field. The 2DEG was formed at the interface of a GaAs/AlxGa1-x As heterojunction. Absorpti...

Phonon Absorption and Emission Experiments in Quantum-Hall-Effect Devices
A two-dimensional electon gas (2DEG) can be formed at the interface between two different semiconductors. This electronic system interacts with the bulk phonons of the substrate material. The matrix element of...

Basic Principles in Hyperthermic Tumor Therapy
The first report of heat being useful in cancer treatment is by Busch (1866), who noted the disappearance of a sarcoma after high fever caused by erysipelas. Bruns (1887) reviewed all cases of tumor regression...

Tierexperimentelle und klinische Anwendung der lokalen Hochfrequenz-Hyperthermie bei Karzinomen der Harnblase
Veröffentlichungen aus neuerer Zeit haben gezeigt, daß Gewebe mit hohen Zellteilungsraten, also insbesondere maligne Gewebe, eine im Vergleich zu normalen Geweben hohe Thermosensibilität besitzen [1]. Auf dies...

Diagnosis of Malignant Lymphoma with 67Gallium
67Gallium shows a tendency to be accumulated in malignant tumors. However, the incorporation of this radioactive nuclide occurs also in acute or chronically inflammable processes (silicosis, tube...
