1. 16. Characterization of oxy-fuel flames - their composition, temperature and radiation

   Författare :Klas Andersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; O2 CO2; NO formation; Radiation; Oxy-fuel; Flame properties;

   Sammanfattning : Oxy-fuel combustion is receiving growing attention as one of the promising CO2 capture technologies in connection to power production. Yet, significant efforts are required in research and development of this combustion process in order to be able to design and optimize a full scale power plant. LÄS MER

3. 17. Developmental Neurotoxicity in Mice Neonatally Co-exposed to Environmental Agents : PCB, PBDE, Methyl Mercury and Ionized Radiation - Interactions and Effects

   Författare :Celia Fischer; Per Eriksson; Anders Fredriksson; Richard Seegal; Uppsala universitet; []
   Nyckelord :Biology; PCB; PBDE; MeHg; ionized radiation; neonatal; development; neurotoxicity; behavior; cholinergic system; Biologi;

   Sammanfattning : This thesis investigates the neurotoxic effects in mice neonatally co-exposed to different toxic environmental agents during a defined critical period of the brains's rapid growth and development. Environmental toxic agents are incorporated in our environment. LÄS MER

4. 18. Radiation Oncology Data and Modelling Side Effects after Radiation Therapy

   Författare :Caroline Olsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dose and side effect data; dose-volume response; fractionation effect; LQ model; sequential two-phase radiotherapy; head and neck cancer; parotid gland; xerostomia; pelvic radiotherapy; gynecological cancer; pubic bone; pain; data integration; xerostomia;

   Sammanfattning : Although modern radiation therapy techniques have the ability to conform the dose distribution of ionizing radiation tightly around the volume to be treated, unwanted irradiation to surrounding organs remains a problem. The probability of a side effect arising in the normal tissue of a patient after radiation therapy can be modelled by sigmoid mathematical functions known as normal tissue complication probability (NTCP) models.

5. 19. Radiation tests of semiconductor detectors

   Författare :Valery Chmill; Bengt Lund-Jensen; Richar Brenner; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; radiation physics; materials science; Nuclear physics; Kärnfysik;

   Sammanfattning : This thesis investigates the response of Gallium Arsenide (GaAs) detectors to ionizing irradiation. Detectors based on π-υ junction formed by deep level centers doping. LÄS MER

7. 20. Cellular effects after exposure to mixed beams of ionizing radiation

   Författare :Elina Staaf; Andrzej Wojcik; Siamak Haghdoost; Eva Forssell-Aronsson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ionizing radiation; high LET; low LET; mixed beams; combined exposure; molekylärgenetik; Molecular Genetics;

   Sammanfattning : Mixed beams of ionizing radiation in our environment originate from space, the bedrock and our own houses. Radiotherapy patients treated with boron neutron capture therapy or with high energy photons are also exposed to mixed beams of gamma radiation and neutrons. LÄS MER
