  2. 1. Theoretical modelling of tumour oxygenation and influences on treatment outcome

    Author : Iuliana Toma-Dasu; Mikael Karlsson; Svensson Hans; J F Fowler; Borivoj Vojnovic; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; Computer simulation; Electrode; Polarographic measurements; Tumour oxygenation; Hypoxia; Strålningsvetenskap; Radiation biology; Strålningsbiologi; radiofysik; radiation physics;

    Abstract : One of the main problems in curing cancer resides in the different microenvironment existing in tumours compared to the normal tissues. The mechanisms of failure are different for radiotherapy and chemotherapy, but they all relate to the poor blood supply known to exist in tumours. READ MORE

  4. 2. Optical Studies For Synchrotron Radiation Beamlines

    Author : Walan Grizolli; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Synchrotron Radiation; Optics; X-ray Optics; Beamline; Polarimetry; Coherence; Storage Rings; Diffraction Limited Storage Rings;

    Abstract : Synchrotron radiation sources have greatly contributed to the progress in many fields of science. The development of the storage ring technologies has made possible to obtain very low emittance electron beams, which together with the use of undulators allow guiding a very high photon flux into a very small spot required by the experiments.

  6. 4. Biological growth on rendered façades

    Author : Sanne Johansson; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temperature; render; radiation; photosynthesis; moulds; mosses; mortar; moisture; lichens; Imaging-PAM; humidity; heat capacity; heat; ETICS; algae; biological growth; calorimetry; desiccation tolerance;

    Abstract : Biological organisms have an incredible ability to adapt to almost any environment and the humans activities on earth have created many new habitats for different kinds of organisms. For example can certain organisms grow on rocks and vertical cliffs, and when humans started building houses with mineral based façades, some organisms found that these were new habitats to live on.
