1. 1. Peripheral nerve function : metabolic features, clinical assessment, and heat shock protein 27

   Författare :Kaveh Pourhamidi; Olov Rolandsson; Lars B Dahlin; Svein-Ivar Mellgren; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Peripheral neuropathy is a common complication among patients with diabetes mellitus, but whether peripheral neuropathy is present in individuals with impaired glucose tolerance (IGT) is debatable. In order to identify and diagnose peripheral neuropathy correctly, it is important to evaluate diagnostic tools that can be implemented in routine health care to assess both large and small nerve fibre function.

3. 2. Physical activity, bone density, and fragility fractures in women

   Författare :Undis Englund; Ulrika Pettersson Kymmer; Peter Nordström; Gustaf Bucht; Karl Obrant; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; physical activity; bone density; neuromuscular function; fragility fractures; women; Geriatrics and medical gerontology; Geriatrik och medicinsk gerontologi; Geriatrics; geriatrik;

   Sammanfattning : Scandinavia has among the highest incidence of fragility fractures in the world. The reasons for this are unknown, but might involve differences in genetic and/or environmental factors, such as sunlight exposure and levels of physical activity. LÄS MER

4. 3. The Effect of Different Perturbations on the Stability Analysis of Light Water Reactors

   Författare :Victor Dykin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; BWR and PWR stability; stability indicators; propagating density perturbation; autocorrelation function; density wave oscillations; decay ratio; non-white driving force; damped harmonic oscillator; reduced order models; Green s function technique;

   Sammanfattning : Neutron noise analysis techniques are studied and developed, with primary useof determining the stability of Boiling Water Reactors (BWRs). In particular, the role ofa specific perturbation prevailing in Light Water Reactors, the propagating densityperturbation, in the stability of BWRs and on the noise field of LWRs in general, isinvestigated by considering three topics.

5. 4. Low-Density Lipoprotein Oxidation and Renal Dysfunction : New Markers of Poor Prognosis in Patients with Unstable Coronary Artery Disease

   Författare :Nina Johnston; Lars Wallentin; Tomas Jernberg; Agneta Siegbahn; Lena Jonasson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; myocardial infarction; unstable angina; oxidized low-density lipoprotein; renal function; prognosis; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

   Sammanfattning : In patients with unstable coronary artery disease (CAD) biochemical markers are emerging as useful tools in clinical management. In this thesis we studied the use of markers of low-density lipoprotein (LDL) oxidation and renal function. LÄS MER

7. 5. Sobolev-Type Spaces : Properties of Newtonian Functions Based on Quasi-Banach Function Lattices in Metric Spaces

   Författare :Lukáš Malý; Anders Björn; Jana Björn; Tomas Sjödin; Andrea Cianchi; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Newtonian space; Sobolev-type space; metric measure space; upper gradient; Sobolev capacity; Banach function lattice; quasi-normed space; rearrangement-invariant space; maximal operator; Lipschitz function; regularization; weak boundedness; density of Lipschitz functions; quasi-continuity; continuity; doubling measure; Poincaré inequality;

   Sammanfattning : This thesis consists of four papers and focuses on function spaces related to first-order analysis in abstract metric measure spaces. The classical (i.e., Sobolev) theory in Euclidean spaces makes use of summability of distributional gradients, whose definition depends on the linear structure of Rn. LÄS MER
