2. 1. Sources of dioxins and other POPs to the marine environment : Identification and apportionment using pattern analysis and receptor modeling

   Author : Kristina Sundqvist; Karin Wiberg; Mats Tysklind; Paul Geladi; Miriam Diamond; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; air-water gas exchange; chiral; congener pattern; enantiomer; enantiomeric fraction; fugacity; HCH; hexachlorocyclohexane; homologue profile; indicator congener; isomer pattern; pattern analysis; PCA; PCB; PCDD F; PMF; polychlorinated dibenzofuran; polychlorinated dibenzo-p-dioxin; polychlorinated biphenyl; positive matrix factorization; principal component analysis; receptor modeling; source apportioning; source; source tracing; Environmental chemistry; Miljökemi; Persistent organic compounds; Persistenta organiska föreningar;

   Abstract : In the studies underlying this thesis, various source tracing techniques were applied to environmental samples from the Baltic region. Comprehensive sampling and analysis of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in surface sediments in Swedish coastal and offshore areas resulted in a unique data set for this region.

4. 2. Automated Tissue Image Analysis Using Pattern Recognition

   Author : Jimmy Azar; Anders Hast; Ewert Bengtsson; Martin Simonsson; Marco Loog; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tissue image analysis; pattern recognition; digital histopathology; immunohistochemistry; paired antibodies; histological stain evaluation; Computerized Image Processing; Datoriserad bildbehandling;

   Abstract : Automated tissue image analysis aims to develop algorithms for a variety of histological applications. This has important implications in the diagnostic grading of cancer such as in breast and prostate tissue, as well as in the quantification of prognostic and predictive biomarkers that may help assess the risk of recurrence and the responsiveness of tumors to endocrine therapy.

5. 3. From pattern to process : Studies on limestone grassland, with emphasis on the bryophyte-lichen layer and its effects on vascular plants

   Author : Manuela Zamfir; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Alvar; Bryophytes; Carousel model; Community structure; Competition; Dynanmics; Interactions; Lichens; PASFRAN; pattern analysis; Sweden; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

   Abstract : Patterns in space and time at different scales in the bryophyte-lichen layer, aud multi-species spatial patterns of bryophytes, lichens and vascular plants were studied in Avenetum limestone grassland on the Great Alvar of the Baltic Island of Öland, south-eastem Sweden.Spatiotemporal patterns of bryophytes and Iichens in grazed and ungrazed alvar grassland demonstrated that dominant species forming large patches were relatively stable in time, whereas less frequent species forming small patches were more mobile.

6. 4. Biomechanical methods and error analysis related to chronic musculoskeletal pain

   Author : Fredrik Öhberg; Mats Djupsjöbacka; Åke Öberg; Högskolan i Gävle; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cervical spine; ensemble theory; error analysis; helical axis; kinematics; movement analysis; neural coding; pattern recognition; spike sorting; whiplash; Medical technology; Medicinsk teknik;

   Abstract : Background Spinal pain is one of humanity’s most frequent complaints with high costs for the individual and society, and is commonly related to spinal disorders. There are many origins behind these disorders e.g., trauma, disc hernia or of other organic origins. READ MORE

7. 5. Prestress in Nature and Technics

   Author : Alexander Sehlström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Geometrical stiffness; Prestress; Form finding; Architecture; Structural design; Stress pattern; Engineering; Conceptual design;

   Abstract : To direct the forces of nature is a central task in the creation of spaces and load-carrying structures for architecture. This research investigates how prestress can be used as a design tool for the creation of material efficient and well-functioning structures, and in early design stages contribute to sustainable, functional and beautiful architecture.
