2. 1. Mass Loss of Evolved Stars : Improving Mass-Loss Rates and Distances

   Author : Miora Andriantsaralaza; Paul Barklem; Elvire De Beck; Susanne Höfner; Jacco van Loon; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; AGB stars; Mass loss; Distance; Circumstellar matter; Radio interferometry; Stellar evolution; Fysik med inriktning mot astrofysik; Physics with specialization in Astrophysics;

   Abstract : In the final stages of their lives, low to intermediate-mass stars enter the Asymptotic Giant Branch (AGB) phase, where they experience significant mass loss through dusty stellar winds. This mass loss is pivotal, not only for the chemical enrichment of the interstellar medium, setting the stage for new stars and planets to form, but also in dictating the evolution and the ultimate fate of the stars themselves.

4. 2. Molecules and Dust around AGB stars : Mass-loss rates and molecular abundances

   Author : Sofia Ramstedt; Hans Olofsson; Fredrik Schöier; José Cernicharo; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; AGB stars; mass-loss; circumstellar abundances; Formation and development of stars; Stjärnors bildning och utveckling; Astronomy; astronomi;

   Abstract : All stars with a stellar mass of about 0.8–8 MSun will end their lives as asymptotic giant branch (AGB) stars. Through their extensive mass loss the AGB stars constitutes an important source of nuclear processed material. READ MORE

5. 3. Rheumatoid Arthritis: Body Composition, Bone Loss, and Mortality

   Author : Christina Book; Malmö Institutionen för kliniska vetenskaper; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fat mass; bone mass; lean mass; body composition; mortality; rheumatoid arthritis; predictors;

   Abstract : Early rheumatoid arthritis (RA) patients (disease duration ≤1 year, n=165) were recruited 1995-2001 and followed systematically clinically and with dual energy X-ray absorptiometry (DXA) over 2 years and compared to age- and gender-matched controls. Baseline arm and leg lean mass were decreased in RA patients in both genders and body mass index and truncal fat distribution were increased in female RA patients. READ MORE

6. 4. Lumbar spinal stenosis : Body mass index and the patient's perspective

   Author : Björn Knutsson; Karl Michaëlsson; Bengt Sandén; Göran Sjödén; Paul Gerdhem; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antonovsky; back pain; BMI; body mass index; Bygghalsan; cohort study; coping; EQ-5D; excess weight; leg pain; LSS; lumbar spinal stenosis; obesity; ODI Oswestry disability index; overweight; patient-centered; patient-physician relationship; patient-perspective; patient-related-outcome-measure; PROMs; qualitative study; spinal stenosis; salutogenesis; salutogenic; sciatica; spine surgery; suffering; Swedish spine register; Swespine; VAS; weight loss; weight change; Orthopaedics; Ortopedi;

   Abstract : During recent decades, lumbar spinal stenosis (LSS) has become the most common indication for spine surgery, a change that coincides with a higher worldwide prevalence of overweight and obesity. Thus, surgical treatment of LSS in the overweight and obese population is common and increasing in scope. READ MORE

7. 5. Transmission loss of vehicle seals

   Author : Qi Li; Leping Feng; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle seals; reverberation room test; contact analysis; simple model; mass law; FEM analysis; distorted circular duct model; Acoustics; Akustik;

   Abstract : Sound transmission loss of vehicle seals was studied in this thesis. Reverberation room test and semi-anechoic chamber test were respectively studied. READ MORE
