2. 1. Homogeneous Ignition - Chemical Kinetic Studies for IC-Engine Applications

   Author : Per Amnéus; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Skeletal mechanism; Mechanism reduction; n-heptane; iso-octane; formaldehyde; methane; Motors and propulsion systems; Motorer; framdrivningssystem; Physics; Fysik; Detailed chemistry; Kinetic calculations; Engine knock; Homogeneous charge compression ignition; HCCI; Fysicumarkivet A:2002:Amnéus;

   Abstract : Calculations on a Homogeneous Charge Compression Ignition (HCCI) engine have been performed. Zero-dimensional models were used. The simplest model compressed the gas to auto-ignition, using temperature and pressure at a certain crank angle position obtained from engine experiments. READ MORE

4. 2. Systems Biology of Type 2 Diabetes in Skeletal Muscle

   Author : Leif Väremo; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; genome-scale metabolic model; metabolism; skeletal muscle; myocyte; type 2 diabetes; network analysis; gene-set analysis; transcriptomics; gene expression; obesity;

   Abstract : Type 2 diabetes (T2D) is a heterogeneous and complex disease that currently affects more than 350 million people worldwide. A wide range of risk factors influence the pathogenesis of T2D, including genetic and epigenetic components, as well as controllable factors such as diet, obesity, and sedentary lifestyle. READ MORE

5. 3. Clinical and genetic studies of three inherited skeletal disorders

   Author : Eva-Lena Stattin; Göran Roos; Niklas Dahl; Jaakko Ignatius; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; skeletal disorders; osteochondritis dissecans; ACAN-gene; multiple epiphyseal dysplasia; brachydactyly type A1; IHH-gene; Medical genetics; Medicinsk genetik; klinisk genetik; Clinical Genetics;

   Abstract : Mutations in genes of importance for cartilage development may lead to skeletal malformations, chondroskeletal dysfunction and increased susceptibility to degenerative joint disease. Characterization of these mutations and identification of molecular pathways for the corresponding gene products have contributed to our understanding of mechanisms regulating skeletal patterning, endochondral ossification and joint formation.

6. 4. Automatic Analysis and Reduction of Reaction Mechanisms for Complex Fuel Combustion

   Author : Daniel Nilsson; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydraulik; Complex fuel combustion; Reduced kinetic models; skeletal mechanism; QSSA; hydraulics; Mechanical engineering; vacuum technology; Maskinteknik; vibration and acoustic engineering; vakuumteknik; vibrationer; akustik; Physics; Fysik; Chemistry; Kemi; Fysicumarkivet A:2001:Nilsson;

   Abstract : This work concentrates on automatic procedures for simplifying chemical models for realistic fuels using skeletal mechanism construction and Quasi Steady-State Approximation (QSSA) applied to detailed reaction mechanisms. To automate the selection of species for removal or approximation, different indices for species ranking have thus been proposed. READ MORE

7. 5. Pharmacological Modulation of Skeletal Homeostasis

   Author : Niklas U. Andersson; Institutionen för experimentell medicinsk vetenskap; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Farmakologi; toxicology; farmakognosi; farmaci; toxikologi; pharmacy; pharmacognosy; Pharmacological sciences; peripheral quantitative computed tomography.; dual energy X-ray absorptiomenty; estrogen; parathyroid hormone; gastrectomy; alendronate; ovariectomy; Bone;

   Abstract : Both ovariectomy (OVX) and gastrectomy (GX) cause osteopenia in several animal species including humans. While the effect of OVX has been ascribed to estrogen deficiency, the underlying mechanism behind GX-induced osteopenia is poorly understood. READ MORE
