  4. 2. Advances in Microwave Hyperthermia Treatment using Time Reversal

    Author : Hana Dobsicek Trefna; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microwave hyperthermia; time reversal; microwave thermometry; annular phased array; amplifier system; treatment planning;

    Abstract : The last twenty years have seen many clinical studies showing the ability of hyperthermia to remarkably enhance response to radiation therapy and chemotherapy. The objective of hyperthermia treatment is to raise the temperature in tumors to therapeutic levels, for a sufficient period of time, in order to achieve cell death or render the cells more sensitive to ionizing radiation and/or chemotherapy.

  6. 4. Enhancing Tropospheric Humidity Data Records from Satellite Microwave and Radiosonde Sensors

    Author : Isaac Moradi; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CDR; climate; microwave; radiosonde; water vapor; remote sensing; antenna; homogenization; humidity; meteorology; troposphere; radio-frequency;

    Abstract : Water vapor is the most dominant greenhouse gas and plays a critical role in the climate by regulating the Earth's radiation budget and hydrological cycle. A comprehensive dataset is required to describe the temporal and spatial distribution of water vapor, evaluate the performance of climate and weather prediction models in terms of simulating tropospheric humidity, and understand the role of water vapor and its feedback in the climate system.
