2. 1. Development of sensitive EPR dosimetry methods

   Author : Håkan Gustafsson; Eva Lund; Anders Lund; Dag Rune Olsen; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electron paramagnetic resonance EPR ; Formic acids; pharmacology; Lithium; Nickel; Radiometry; Rhodium; Pharmaceutical chemistry; Farmaceutisk kemi;

   Abstract : Electron paramagnetic resonance (EPR) dosimetry using the well established dosimeter material alanine is a generally accepted dosimetric method for measurements of high absorbed doses. Alanine EPR dosimetry is however not sensitive enough for high precision measurements of low (< 5 Gy) absorbed doses using reasonably measurement times and small dosimeters. READ MORE

5. 3. Measuring quality of occupational performance based on self-report and observation : development and validation of instruments to evaluate ADL task performance

   Author : Eva Ejlersen Waehrens; Anne G Fisher; Hans Lund; Bente Danneskiold-Samsöe; Lena von Koch; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; activities of daily living; acquired brain injury; ADL evaluation; ADL task performance; chronic disease; chronic widespread pain; interview; observation; occupational therapy; observation-based evaluation; questionnaire; Rasch measurement; rheumatic diseases; Occupational therapy; Arbetsterapi; Occupational therapy; arbetsterapi;

   Abstract : Background People with rheumatic or neurologic conditions are commonly referred for occupational therapy because of decreased ability to perform ADL tasks. Upon referral, occupational therapists use a client-centred, occupationfocused approach when evaluating a person's perceived and observed quality of ADL task performance to clarify the nature and extent of the person’s problems, plan interventions and determine effectiveness of interventions.

6. 4. Lithium formate EPR dosimetry for accurate measurements of absorbed dose in radiotherapy

   Author : Emelie Adolfsson; Åsa Carlsson Tedgren; Eva Lund; Håkan Gustafsson; Sara Olsson; Gudrun Alm Carlsson; Peter Sharpe; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Lithium formate has shown to be a material with properties suitable for electron paramagnetic resonance (EPR) dosimetry, among them up to 7 times higher sensitivity compared to alanine, which is a well-established EPR detector material for dose determinations in radiotherapy.The aim of this thesis was to further investigate the properties of lithium formate and develop the dosimetry system towards applications in radiotherapy.

7. 5. From Particle-Production Cross Sections to KERMA and Absorbed Dose for the Case 96 MeV n-12C Interactions

   Author : Bel E. Bergenwall; Ayşe Ataç; Eva Lund; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Fast neutrons; En = 96 MeV; charged-particle production; 12C n; px ; 12C n; dx ; 12C n; tx ; 12C n; 3Hex ; 12C n; ax reactions; cross sections; KERMA; microscopic measurements; absorbed dose; Kärnfysik; Nuclear physics; Kärnfysik;

   Abstract : Neutron-carbon interactions have been studied with a focus on charged-particle production of relevance to radiation protection and medical applications, such as cancer therapy. The measurements have been performed using the particle-detection setup, MEDLEY, and the 96 MeV neutron beam at the The Svedberg Laboratory in Uppsala. READ MORE
