1. 1. A Parametric Approach to Yeast Growth Curve Estimation and Standardization

   Författare :Ilona Pylvänäinen; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bioscreen; Chapman-Richards model; growth curve; growth rate; lag time; optical density OD ; Saccharomyces cerevisiae; standardized curve; stationary phase OD increment; summary curve; optical density OD ;

   Sammanfattning : The purpose of this thesis is to contribute to the understanding of yeast growth. It builds upon a dataset consisting of growth curves of 576 Saccharomyces cerevisiae mutants in eight different environments. The data will be a part of a publicly available phenotypic library, PROPHECY, containing growth curves and characteristics of viable S. LÄS MER

4. 3. Symphysis Fundus Measurements for Detection of Intrauterine Growth Retardation

   Författare :Eva Bergman; Ove Axelsson; Helle Kieler; Max Petzold; Reynir Tomas Geirsson; Uppsala universitet; []
   Nyckelord :symphysis-fundus measurements; small for gestational age; intrauterine growth retardation; fetal growth; self-administered; relative growth; screening method; statistical surveillance; fetal surveillance;

   Sammanfattning : A case-control study was performed to evaluate the Swedish population-based symphysis fundus (SF) reference curves. The study included 242 small for gestational age (SGA) neonates (169 term and 73 preterm infants) as cases and 296 non-SGA infants as controls. Two Swedish SF curves were evaluated. LÄS MER

5. 4. Born Globals : Rapid International Growth in New Ventures

   Författare :Ingemar Wictor; Svante Andersson; Tomas Müllern; Sören Sören Kock; Högskolan i Halmstad; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Born Global; internationalisation; entrepreneur; network; vision; value chain; growth; management; leadership; entrepreneurial teams;

   Sammanfattning : The traditional theories developed by Johanson and Vahlne (1977, 1990) and other researchers ofinternationalisation have long been questioned because of the fast-changing environment and deregulations. In particular, for Born Global firms, namely a company that has achieved a foreign sales volume of at least 25% within three years of its inception and that seeks to derive significant competitive advantage from the use of resources and the sales of outputs in multiple countries (Andersson and Wictor, 2003, p.

7. 5. Bioenergy, pollution, and economic growth

   Författare :Mattias Ankarhem; Runar Brännlund; David Stern; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Forest sector; Forest fuels; Dynamic factor demand; Adjustment costs; Economic growth; Pollution; Environmental Kuznets curve; Shadow price; Distance function; Nationalekonomi; Economics; Nationalekonomi; Economics; nationalekonomi;

   Sammanfattning : This thesis consists of four papers: two of them deal with the effects on the forest sector of an increase in the demand for forest fuels, and two of them concern the relation between economic growth and pollution. Paper [I] is a first, preliminary study of the potential effects on the Swedish forest sector of a continuing rise in the use of forest resources as a fuel in energy generation. LÄS MER
