4. 2. Systemic sclerosis : vascular, pulmonary and immunological aspects

   Author : Grethe Neumann Andersen; Solbritt Rantapää Dahlqvist; Lucia Mincheva-Nilsson; Sören Jacobsen; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Systemic sclerosis; interstitial lung disease; MMP-9; Th1 Th2; transcription factors; NO; iNOS; E-selectin; endothelium-dependent dilation; endothelium-independent dilation.; Rheumatology; Reumatologi;

   Abstract : In systemic sclerosis (SSc), interstitial lung disease (ILD) and engagement of the vascular system lead to increased morbidity and mortality. The aim of this thesis was to elucidate, in a consecutively included cohort of SSc (limited and diffuse) patients (n = 33), the T cell cytokine profile driving the disease in ILD and to explore the role of matrix metalloproteinase 9 (MMP-9) and its inhibitor: tissue inhibitor of metalloproteinase 1 (TIMP-1) in the extracellular matrix (ECM) degrading process leading to fibrous scarring and honey combing.

5. 3. Thermal Crack Risk Estimation and Material Properties of Young Concrete

   Author : Anders Hösthagen; Jan-Erik Jonasson; Mårten Larson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal cracking risk; young concrete; Equivalent Restraint Method; strength development; heat of hydration; creep; shrinkage; thermal dilation; modeling; field observations; Structural Engineering; Konstruktionsteknik;

   Abstract : This thesis presents how to establish a theoretical model to predict risk of thermal cracking in young concrete when cast on ground or an arbitrary construction. The crack risk in young concrete is determined in two steps: 1) calculation of temperature distribution within newly cast concrete and adjacent structure; 2) calculation of stresses caused by thermal and moisture (due to self-desiccation, if drying shrinkage not included) changes in the analyzed structure.

6. 4. The perception of actions and interactions : And the importance of context

   Author : Joshua Juvrud; Gustaf Gredebäck; Denis Mareschal; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; action understanding; action perception; motion; perception; context; environment; eye-tracking; pupil dilation; Psychology; Psykologi;

   Abstract : The perception of actions and interactions is a dynamic process linked with perceptual processes, the internal and external states of the individual, prior experiences, and the immediate environment. Given these differential contexts, it is very likely there are differences in how infants perceive, interpret, and respond to actions. READ MORE

7. 5. Clinical Studies on Dark Adaptation: with Particular Reference to Carotid Artery Disease

   Author : Ulf Havelius; Oftalmologi (Malmö); []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; polycythemia; photoreceptors; phlebotomy; ocular blood flow; headache; dilation lag; dark adaptometry; dark adaptation; color Doppler imaging; carotid artery stenosis; carotid artery disease; carotid endarterectomy; pupil; pupillometry; retinal blood flow; Ophtalmology; Oftalmologi;

   Abstract : Purpose: To study dark adaptation in patients with symptomatic carotid artery disease or polycythemia before and after treatment. This necessitated determinations of pupillary changes as such may influence the findings. To determine whether changes in the retinal blood flow in light and darkness occur in healthy humans.
