1. 1. Irradiation of members of the general public from radioactive caesium following the Chernobyl reactor accident. Field studies in a highly contaminated area in the Bryansk region, Russia

   Författare :Charlotte Thornberg; Malmö Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi; body burden; Effective dose; Cs-137; urinary excretion; Cs-134; biological half-time; Chernobyl; breast milk; Medicine human and vertebrates ; internal irradiation; external irradiation; TLD; Clinical physics; radiology; medical instrumentation; tomography; Medicin människa och djur ; Physics; Fysik;

   Sammanfattning : From 1990 to 1998, estimations of the effective dose from external as well as internal irradiation from 137Cs and 134Cs were carried out for inhabitants in rural villages in the Bryansk region, Russia, highly contaminated due to the Chernobyl accident in 1986. The villages were situated about 180 km from the Chernobyl power plant and the deposition of 137Cs was in the range 0. LÄS MER

3. 2. Internal dosimetry. Macroscopic, small-scale and microscopic perspectives

   Författare :Cecilia Hindorf; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiobiologi; Nukleärmedicin; radiobiology; Nuclear medicine; B-cell lymphoma; Radioimmunotherapy; Radionuclide therapy; Internal dosimetry; Radiopharmaceutical technology; Radiofarmaceutisk teknik;

   Sammanfattning : Internal dosimetry deals with the assessment of absorbed dose for radionuclides distributed inside the body. The absorbed dose is in its turn used for correlation with the biological effect caused by the irradiation. LÄS MER

4. 3. Carbohydrate-Functionalized Nanomaterials : Synthesis, Characterization and Biorecognition Studies

   Författare :Na Kong; Mingdi Yan; Joseph J. Barchi Jr; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbohydrate; glyconanomaterials; perfluorophenyl azide PFPA ; CuAAC; AAAC; coupling chemistry; 19 F q NMR; lectin; carbon nanomaterials; microwave irradiation; Kemi; Chemistry; Bioteknologi; Biotechnology;

   Sammanfattning : This thesis focuses on the development of carbohydrate coupling chemistry on nanomaterials and their biological activity studies. It is divided into two parts:In part one, two carbohydrate immobilization approaches, based on perfluorophenyl azide (PFPA)-functionalized silica nanoparticles (SNPs), are presented, where the binding affinity of the glyconanoparticles was evaluated through carbohydrate-lectin interaction.

5. 4. Free cooling in commercial buildings. Application with evaporative cooling tower and chilled beams

   Författare :Bengt Bergsten; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooling tower; commercial buildings; simulation; low energy cooling; evaporative cooling; hydronic cooling system; internal heat gain; free cooling; chilled beams; methodology;

   Sammanfattning : The use of electricity in commercial buildings has increased over the last decades. One major cause is the rapid escalation of air conditioning equipment together with a growth of internal heat gains originating mainly from an increased amount of office equipment, which also use electric energy, and high levels of solar irradiation.

7. 5. The Importance of Dosimetry and Radiobiology in Nuclear Medicine : Quantitative methods and modelling

   Författare :Anna Stenvall; Lund Medicinsk strålningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear medicine; radionuclide therapy; radiopharmaceutical therapy; dosimetry; Monte Carlo modelling; radiobiology; ; γH2AX; DOTA-TATE; PET; SPECT;

   Sammanfattning : Nuclear medicine uses radioactive pharmaceuticals for diagnostic or therapeutic purposes. The ionizing radiation emitted from the radiopharmaceutical is partially absorbed within the patient's body and internal dosimetry is the method to estimate the absorbed dose to a tumour or risk organ.
