  2. 11. Risk Factors for Diabetic Ketoacidosis in Children

    Author : Johan H Wersäll; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diabetic ketoacidosis; Type 1 diabetes; Continuous subcutaneous insulin infusion; Multiple daily injections; Cerebral edema; Socioeconomic status; Low economic standard; Level of education;

    Abstract : Background: Diabetic ketoacidosis (DKA) is a life-threatening acute complication of diabetes. It is preventable if timely administration of sufficient amounts of insulin is initiated. A large proportion of children are affected by DKA annually, especially at onset of type 1 diabetes (T1D). READ MORE

  4. 12. Multi-Dimensional Quantitative Laser-based Diagnostics - Development and Practial Applications

    Author : Rikard Wellander; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Post injection; Structured illumination; Mie scattering; Dense sprays; Extinction coefficient; Signal attenuation; Laser extinction; Multiple scattering; Scattering measurements; Planar laser induced fluorescence; Time resolved; Imaging through turbulent media; Three-dimensional image acquisition; Diesel particulate filter regeneration; Wall impingent; Biodiesel; LII; Large-bore gas Engine; Pre-chamber ignition; Fysicumarkivet A:2014:Wellander;

    Abstract : Laser based optical diagnostic methods are routinely used in combustion research. Many of the more common approaches are based on illuminating a cross-section of the sample with a thin laser sheet. For example, by targeting an electronic transition in a molecule, its concentration within the plane illuminated by the laser sheet can be deduced. READ MORE

  5. 13. Investigation of Partially Premixed Combustion in an Optical Engine : In-Cylinder Flow and Combustion Characterization

    Author : Slavey Tanov; Förbränningsmotorer; []
    Keywords : PPC; in-cylinder flow structures; Combustion diagnostics; Gasoline; Gasoline-Ethanol; Multiple Injection; Stratification Level;

    Abstract : The diesel engine is one of the most economic power sources and is therefore used in a range of technical solutions. The low fuel consumption combined with high engine performance makes it attractive for transportation vehicles. READ MORE

  6. 14. On the Combustion Characteristics of Closely-Coupled LD Diesel Injection Strategies

    Author : Michael Denny; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel combustion; Closely-Coupled Pilot; Closely-Spaced Pilot; Combustion Noise; Heat release rate shaping; Multiple-injection strategy; Formaldehyde PLIF;

    Abstract : Multiple-pilot injection strategies with both moderate and short time separations (dwells) are investigated in a light-duty diesel engine. Both conventional and optical engine experiments are performed. READ MORE

  7. 15. Optical Diagnostics for Engine Efficiency in Gasoline Compression Ignition

    Author : Miao Zhang; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PPC; Optical engine; Engine Eciency; Multiple-injection strategies; Thermodynamic analysis;

    Abstract : The internal combustion engine has played a significant role in a vast number of applications from small cars to giant tankers, setting people free from geographical barriers and heavy labor. However, it has also generated many tons of harmful emissions and CO2that damage to humans and the environment. READ MORE
