2. 1. Radiobiological end-points for the theoretical evaluation of the effectiveness of carbon ions and photons in treating tumours with dynamic hypoxia

   Author : Antonovic Laura; Iuliana Toma-Dasu; Tatsuaki Kanai; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; OER; hypoxia; LOC; RCR; hypofractionation; SBRT; carbon ion; fractionation; TCP; SF; RCE; RBE; Medical Radiation Physics; medicinsk strålningsfysik;

   Abstract : Tumours are characterised by unorganised vasculature, which often results in hypoxic regions. Hypoxia is a common cause for photon radiotherapy (RT) treatment failure, as hypoxic cells require up to 2-3 times higher doses compared to well-oxygenated cells for the same effect in terms of cell kill.

4. 2. InGaAs/AlGaAs Heterojunction Phototransistors for Optical Signal Processing Applications

   Author : Ola Sjölund; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis deals with InGaAs/AlGaAs heterojunction phototransistors (HPTs) operating in the wavelength region where the GaAs substrate is transparent. Vertical integration of such a current amplifying detector with emitters or modulators will facilitate the fabrication of two dimensional arrays of components for parallel optical signal processing and transmission applications.
