2. 11. Elastohydrodynamically lubricated finite line contacts operating under transient conditions

   Author : Tobias Hultqvist; Roland Larsson; Lars-Erik Stacke; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

   Abstract : The effect of greenhouse gas emissions contributing to the global warming is today becoming an increasingly important problem worldwide and has led to increased efforts being made on improving tribological performance of interacting surfaces in mechanical systems. Due to increasingly stringent CO2regulations, a reduced fuel consumption has become a key area of interest for the automotive industry where low cost, low emission solutions are continuously developed and where low friction alternatives to machine elements currently in use are evaluated.

4. 12. Quantitative diffuse reflectance spectroscopy : myocardial oxygen transport from vessel to mitochondria

   Author : Tobias Lindbergh; Tomas Strömberg; Henrik Ahn; Marcus Larsson; Lise Lyngsnes Randeberg; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : In the field of biomedical optics, diffuse reflectance spectroscopy (DRS) is a frequently used technique for obtaining information about the optical properties of the medium under investigation. The method utilizes spectral difference between incident and backscattered light intensity for quantifying the underlying absorption and scattering processes that affects the light-medium interaction.

5. 13. The Role of Fibroblast Growth Factor 23 in Phosphate Homeostasis

   Author : Tobias Erik Martin Larsson; Kenneth Jonsson; Östen Ljunggren; Suzanne Jan De Beur; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Fibroblast Growth Factor 23; FGF-23; phosphate homeostasis; vitamin D metabolism; sodium phosphate cotransporters; autosomal dominant hypophosphatemic rickets; ADHR; X-linked hypophosphatemic rickets; XLH; oncogenic osteomalacia; OOM; PHEX; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

   Abstract : The regulation of serum phosphate (Pi) concentrations is a complex process and our current models are far from complete. Due to major advancements in biotechnology and the development of more powerful research tools, recent advances in the field of genetics has led to the identification of several candidates for the long sought-after phosphatonin(s), or Pi regulating hormones.

6. 14. Transient elastohydrodynamic lubrication : Effects of geometry, surface roughness, temperature, and plastic deformation

   Author : Tobias Hultqvist; Roland Larsson; Pär Marklund; Wassim Habchi; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

   Abstract : The urgent need to reduce greenhouse gas emissions in combination with an increased use of sustainable energy resources have led to immense efforts on improving energy efficiency of mechanical systems. Consequently, modern machine elements are typically lubricated with low viscosity oils and designed to endure an increasingly high power density. READ MORE

7. 15. Decision Analysis in Situations with Conflicting Interests

   Author : Tobias Fasth; Aron Larsson; Love Ekenberg; Lisa Brouwers; Valentina Ferretti; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Multiple Criteria Decision Analysis; Portfolio Decision Analysis; Conflict Analysis; Decision Tools; Land Use Planning; Computer and Systems Sciences; data- och systemvetenskap;

   Abstract : Decision problems in participatory decision making involve multiple stakeholders, who often have conflicting preferences concerning the actions under consideration. Decision problems such as these can be structured as multi-criteria problems, which enables the actions to be evaluated in terms of more than one single criterion. READ MORE
