  2. 1. Development and Applications of Detailed Kinetic Models for the Soot Particle Size Distribution Function

    Author : Karl Netzell; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; flamelet model; Physics; particle distribution; soot; moment method; sectional method; particle size distribution function;

    Abstract : Two different mathematical methods of implementing a detailed kinetic soot model have been employed in this work. The theoretical description of the soot modeling employed in this work is divided into three parts. Initially a detailed kinetic soot model is described from a chemistry and physics perspective.

  4. 2. A Detailed Kinetic Model for Calculation of the Soot Particle Size Distribution Function

    Author : Fikret Saric; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gaser; fluiddynamik; plasma; Motors and propulsion systems; Motorer; framdrivningssystem; plasmas; fluid dynamics; Gases; Fysik; Physics; Computational Fluid Dynamics; Sectional Method; Method of Moments; Diesel Like Engine Condition; Distribution Function; Detailed Kinetic Soot Model; Soot Particle Size;

    Abstract : The soot particle size distribution was studied via numerical simulation under diesel like engine conditions using a detailed kinetic soot model. Two different mathematical methods of the soot model description have been used in this work. In the first part of the work, the method of moments is presented. READ MORE

  5. 3. Happy with the method? : Sexual function changes in young women using contraception

    Author : Agota Malmborg; Mats Hammar; Jan Brynhildsen; Alkistis Skalkidou; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Background: Sexuality and contraception are closely linked topics. In theory, hormonal contraception use might affect female sexual function in both positive and negative directions. Some women experience and report adverse sexual function changes while they use hormonal contraception while others report no or positive changes. READ MORE

  6. 4. New Venture, Survival, Growth : Continuance, Termination and Growth of Business Firms and Business Populations in Sweden During the 20th Century

    Author : Marcus Box; Karl Gratzer; Johan Söderberg; Johan Wiklund; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; firm growth; firm death; firm survival; firm performance; firm populations; business dynamics; cohort method; longitudinal method; business demography; liability of newness; liability of smallness; entrepreneurship; small and medium enterprises; business history; size distribution; ownership; succession; Economic history; Ekonomisk historia; Business studies;

    Abstract : This dissertation focuses on the formation, growth and discontinuance of business populations and firms in Sweden during the 20th century. It addresses some key issues in the domain of economic and social sciences, and in particular entrepreneurship and small business research: if and when firms grow, stagnate and decline, as well as how long firms survive and when they are likely to disband.
