1. 6. Magnetic Ordering in Layered Magnets

   Författare :Moreno Marcellini; Björgvin Hjörvarsson; Roger C.C Ward; Uppsala universitet; []
   Nyckelord :Physics; Magnetic thin films and superlattices; Magnetic phase transitions; Polarized neutron reflectometry; Fysik;

   Sammanfattning : The preparation of layered magnets needs the knowledge of growth techniques which are focused on the growth of Fe/V(001) superlattices. Such films have been structurally investigated by X-rays reflectivity and diffraction. LÄS MER

3. 7. Electrical Transport in Nanoparticle Thin Films of Gold and Indium Tin Oxide

   Författare :Jesper Ederth; Knut Deppert; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Electrical transport; Nanoparticle; Nanocrystalline; Materialvetenskap; Materials science; Teknisk materialvetenskap; English; engelska;

   Sammanfattning : Electrical transport properties of nanoparticle gold films made by the gas evaporation method were analysed using resistivity measurements. Low temperature electrical transport measurements showed a cross-over from a temperature range dominated by inelastic scattering to a temperature range dominated by elastic scattering, presumably by grain boundaries.

4. 8. Effects of cigarettes, e-cigarettes and Swedish snus on vascular function

   Författare :Lukasz Antoniewicz; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Cigarette smoking is considered one of the leading causes of preventable morbidity and premature death worldwide. A large portion of this is attributable to cardiovascular disease such as ischemic heart disease and stroke. LÄS MER

5. 9. Pain in pediatric oncology : Diagnostics and treatment

   Författare :Gustaf Ljungman; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics and gynaecology; adolescence; child; pain; neoplasms; cancer; educational needs; pediatric procedure sedation; anxiety procedure; administration intranasal; conscious sedation; general anesthesia; lumbarpuncture; Obstetrik och kvinnosjukdomar; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; pediatrik; Pediatrics;

   Sammanfattning : Pain treatment is a crucial aspect in the care of children with cancer and several studies demonstrate inefficient pain treatment. The general aims of the thesis were to identify the current pain problems in pediatric oncology, and to see whether specific interventions could improve the situation. LÄS MER

7. 10. The role of the CdS buffer layer in the Cu(In,Ga)Se2 thin film solar cell

   Författare :Angela Kylner; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Materialvetenskap; Materials Science;

   Sammanfattning : The Cu(In,Ga)Se2 thin film solar cell is one of the most promising candidates for low-costand high-efficiency solar cells. To date efficiencies approaching 18% have been achieved whenincluding a thin CdS layer prepared by chemical bath deposition (CBD) between theCu(In,Ga)Se2 and ZnO layers. LÄS MER
