  4. 8. Essays on Economic Modeling of Climate Change

    Författare :Gustav Engström; John Hassler; Michael Hoel; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; climate change; economic growth; energy balance models; sustainability; Economics; nationalekonomi;

    Sammanfattning : Structural change in a two-sector model of the climate and the economy introduces issues concerning substitutability among goods in a two-sector economic growth model where emissions from fossil fuels give rise to a climate externality. Substitution is modeled using a CES-production function where the intermediate inputs differ only in their technologies and the way they are affected by the climate externality. LÄS MER

  5. 9. Ethyl Cellulose Membranes used in Modified Release Formulations

    Författare :Johan Hjärtstam; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; osmotic pumping; water permeability; drug release; reflectivity; ethyl cellulose; degree of substitution; mechanical strength;

    Sammanfattning : Ethyl cellulose (EC) is a commonly used polymer in modified drug release formulations. The general aim of the present study was to investigate release mechanisms through non-porous EC membranes with hydroxypropyl methyl cellulose (HPMC) contents ranging from 0 to 30% by weight.

  7. 10. Essays on the Infestation of Lake Victoria by the Water Hyacinth

    Författare :Eseza Kateregga; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Water hyacinth; water hyacinth indicators; water hyacinth induced catchability coefficients; intrinsic growth rates for stocks; carrying capacity; elasticity of catch with respect to fishing effort; electricity outage costs.;

    Sammanfattning : This thesis consists of four essays that seek to estimate the abundance of the water hyacinth in Lake Victoria during the 1990s and analyse its effects on the catchability of fish, estimate the elasticities of catch with respect to the various components of effort in lake Victoria fisheries, and estimate the welfare costs of electricity outages. In the first essay, data on the extent of water hyacinth mat coverage collected from a number of reports and surveys is used to fit time trend water hyacinth mats growth curves for the three sections of Lake Victoria.
