1. 6. Spatial analysis and modeling of nerve fiber patterns

   Författare :Claes Andersson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hierarchical models; Bayesian estimation; epidermal nerve fibers; cluster processes; spatial point processes; diabetic neuropathy; Bayesian field theory; Diabetic neuropathies; Multilevel models Statistics ; Institutionen för matematiska vetenskaper.

   Sammanfattning : Diabetic neuropathy is a condition associated with diabetes affecting the epidermal nerve fibers (ENFs). This thesis presents analysis methods and models for ENF data, with two main puroposes: to find early signs of diabetic neuropathy and to characterize how this condition changes the nerve fiber structure.

3. 7. Statistical methods for early discovery of diabetic neuropathy using epidermal nerve fiber data

   Författare :Claes Andersson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diabetic neuropathy; Epidermal nerve fibers; Hierarchical models; Point processes; Reactive territory; Diabetic neuropathy;

   Sammanfattning : The main aim with the work in this thesis is to increase the understanding of the effects diabetic neuropathy has on the epidermal nerve fibers and thereby find methods to detect the disorder at an earlier stage. Epidermal nerve fibers (ENFs) are small sensory nerve fibers in the skin, sensing heat and pain. LÄS MER

4. 8. Urban Evolution

   Författare :Claes Andersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In nature, objects formed from a dynamics on one level often form yet new objects and new dynamics on a new level. This process generates a hierarchical organization of nature that is particularly tall for objects that are of biological or human origin. LÄS MER

5. 9. Chemistry of Carbon Nanostructures : Functionalization of Carbon Nanotubes and Synthesis of Organometallic Fullerene Derivatives

   Författare :Claes-Henrik Andersson; Helena Grennberg; Nazario Martín León; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbon nanotubes; Fullerenes; Purification; Functionalization; Organometallic complexes; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

   Sammanfattning : This thesis is based on two main parts. The first part concerns purification and functionalization of carbon nanotubes (papers I-III), and the second part is related to the synthesis of organometallic fullerene derivatives (papers IV-VII): Two oxidative methods involving aqueous nitric acid were compared with respect to their capability to introduce carboxylic groups into single walled carbon nanotubes, and several literature methods for esterification and amidation of these groups have been evaluated with focus on efficiency and reproducibility in forming covalently functionalized products soluble in organic media.

7. 10. Gränsdragningar i Vårdens Vardag : Hanteringen av arbetsrelaterad psykisk ohälsa i det svenska välfärdssystemet

   Författare :Réka Andersson; Per Gyberg; Claes-Fredrik Helgesson; Ulrika Winblad; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Healthcare practice; management; work-related mental ill health; responsibility; complex problems; knowledge infrastructure; boundary work; occupational health care; primary care; the Swedish welfare system; Vårdens vardag; hantering; arbetsrelaterad psykisk ohälsa; ansvar; komplexa problem; kunskapsinfrastruktur; gränsarbete; företagshälsovård; primärvård; det svenska välfärdssystemet;

   Sammanfattning : Psykisk ohälsa i arbetslivet är ett stort och växande problem i välfärdssamhället. Problemet har flera bottnar och väcker många frågor om vem som har ansvar, vad det egentligen är för ett slags fenomen och hur det bör hanteras. LÄS MER
