2. 1. Radiation induced losses in Ytterbium doped laser materials

   Author : Sara Rydberg; Magnus Engholm; Hans-Erik Nilsson; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : In this work, two types of ytterbium (Yb) doped laser materials are studied, crys-talline Yb:YAG and amorphous Yb/Al silica in both preform and fiber. Yb is suitableas a laser ion because of its simple energy level structure and low quantum defect. READ MORE

4. 2. Satellite microwave measurements of cloud ice properties

   Author : Bengt Rydberg; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; sub-mm; cirrus; upper troposphere; Odin; remote sensing; CloudSat; data retrieval;

   Abstract : Upper tropospheric cloud ice and water vapour are two intimately connected components of the atmosphere, that influence the Earth's energy budget. The response of these components to a warming climate is not well understood. READ MORE

5. 3. Long QT syndrome in Sweden : founder effects and associated cardiac phenotypes

   Author : Annika Winbo; Annika Rydberg; Eric Schulze-Bahr; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long QT Syndrome; Jervell and Lange-Nielsen Syndrome; inherited arrhythmia; founder effects; clinical genetics; haplotype analysis; mutation age; founder mutation; clinical phenotype; life-threatening cardiac events; mutation-specific; KCNQ1 gene; modifier genes; sequence variants; risk stratification; risk factor; gender; pediatrik; Pediatrics;

   Abstract : Background: We aimed to increase the knowledge regarding the familial arrhythmogenic disorder Long QT Syndrome (LQTS) and its recessive variant Jervell and Lange-Nielsen Syndrome (JLNS) in Sweden, including prevalences and clinical phenotypes. A specific focus was directed towards two KCNQ1 mutations –p.Y111C and p. READ MORE

6. 4. Dental caries and background factors in children with heart disease

   Author : Linda Rosén; Christina Stecksén-Blicks; Annika Rydberg; Göran Dahllöf; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; attitudes; caries; children; dental care; heart disease; medication; saliva; Paedodontics; Pedodonti; odontologi; Odontology;

   Abstract : Congenital heart disease (CHD) is one of the most common congenital anomalies with an incidence of approximately 8–10 cases per 1000 live births. Technical development and continuing improvement in surgical methods have led to early interventions and an increased survival and consequently also a new group of patients in dentistry. READ MORE

7. 5. The effect of pressure afterload due to aortic coarctation on left ventricular function in children

   Author : Haki Jashari; Michael Henein; Annika Rydberg; Katarina Hanséus; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coarctation of the aorta; congenital aortic stenosis; left ventricle; myocardial deformation imaging; speckle tracking echocardiography; longitudinal strain; aorto-septal angle; children; kardiologi; Cardiology;

   Abstract : Background:Coarctation of the aorta (CoA) is a congenital heart disease which represents a narrowing of the proximal descending aorta, hence increasing pressure afterload to the left ventricle (LV). Conventional treatment of native CoA is surgical repair, however potential recurrence or other related complications e.g. READ MORE
