1. 16. Compression analysis as a tool for technical characterization and classification of pharmaceutical powders

   Författare :Josefina Nordström; Göran Alderborn; Maria Strömme; Katharina Picker-Freyer; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; compaction; compression; granules; Kawakita; mechanical properties; particles; PAT; pharmaceutical powders; tablets; Pharmaceutics; Galenisk farmaci;

   Sammanfattning : There are today strong incentives for an increased understanding of material properties and manufacturing processes to facilitate the development of new technologies in the pharmaceutical industry. The purpose of this thesis was to suggest methods requiring a low sample amount for characterization of technical properties of powders. LÄS MER

3. 17. Left Ventricular Systolic Dysfunction in 75-year-old Men and Women : A Community-based Study of Prevalence, Screening and Mitral Annulus Motion for Diagnosis and Prognostics

   Författare :Pär Hedberg; Tommy Jonason; Ivar Ringqvist; Eva Nylander; Uppsala universitet; []
   Nyckelord :Medical sciences; Aged; Heart Failure; Ventricular Function; Prevalence; Echocardiography; Electrocardiography; Natriuretic Peptide; Mortality; MEDICIN OCH VÅRD; MEDICINE; MEDICIN;

   Sammanfattning : Reduced performance of the left ventricle to eject blood – left ventricular systolic dysfunction (LVSD) – is a common predecessor of the heart failure syndrome. With or without symptoms, LVSD is associated with a poor prognosis. LÄS MER

4. 18. Cervical influence on dizziness and orientation

   Författare :Eva-Maj Malmström; Människan i rörelse: hälsa och rehabilitering; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neck pain; Muscle fatigue; Vestibular diseases; Cervical range of motion; Cervical spine; 3-D movement analysis; Dizziness; Proprioception; Primary and coupled movements; Physiotherapy;

   Sammanfattning : The overall aim of the work was to examine the influence of cervical biomechanical conditions on movement performance, to study musculoskeletal findings accompanying possible cervicogenic dizziness and to evaluate the influence of cervical proprioception on head orientation. Two devices, measuring cervical range of motion, were compared: Myrin, an inclinometer/compass method and Zebris®, a 3-dimensional ultrasound movement analyser. LÄS MER

5. 19. Optical parametric amplification with periodically poled KTiOPO4

   Författare :Anna Fragemann; Fredrik Laurell; Ebrahim-Zadeh Majid; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nonlinear optics; optical parametric amplification; optical parametric generation; optical parametric oscillation; Optical physics; Optisk fysik;

   Sammanfattning : This thesis explores the use of engineered nonlinear crystals from the KTiOPO4 (KTP) family as the gain material in optical parametric amplifiers (OPAs), with the aim to achieve more knowledge about the benefits and limitations of these devices. The work aims further at extending the possible applications of OPAs by constructing and investigating several efficient and well performing amplifiers. LÄS MER

7. 20. Pulp strength enhancement by oxygen delignification

   Författare :Claudia Esteves; Elisabet Brännvall; Olena Sevastyanova; Sören Östlund; Christine Chirat; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber charge; morphology; oxygen delignification; swellability; tensile properties; dragegenskaper; fiberladdningar; morfologi; svällningsförmåga; syrgasdelignifiering; Chemical Engineering; Kemiteknik;

   Sammanfattning : Oxygen delignification is widely used in the pulp and paper industry as a part of delignification process between the kraft cook and bleaching. However, its potential has not been fully utilized. LÄS MER
