  1. 1. Drug Analysis : Bioanalytical Method Development and Validation

    Författare :Mikaela Malm; Yngve Bergqvist; Anders Colmsjö; Uppsala universitet; []
    Nyckelord :Analytical chemistry; African trypanosomiasis; calibration model; chiral chromatography; dried blood spots; eflornithine; evaporative light-scattering detection; HIV AIDS; lamivudine; liquid chromatography; malaria; nevirapine; piperaquine; pneumonia; solid-phase extraction; sulfadoxine; sulfamethoxazole; validation; zidovudine; Analytisk kemi;

    Sammanfattning : This thesis describes bioanalytical methods for drug determination in biological matrixes, with drugs in focus used against diseases largely affecting low-income countries. Solid-phase extraction is used for sample cleanup, and processed samples are analyzed by liquid chromatography. LÄS MER

  3. 2. The material distribution method : analysis and acoustics applications

    Författare :Fotios Kasolis; Martin Berggren; Volker Schulz; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material distribution method; fictitious domain method; finite element method; Helmholtz equation; linear elasticity; shape optimization; topology optimization;

    Sammanfattning : For the purpose of numerically simulating continuum mechanical structures, different types of material may be represented by the extreme values {,1}, where 0.... LÄS MER

  4. 3. A pseudoparabolic reaction-diffusion-mechanics system : Modeling, analysis and simulation

    Författare :Arthur Vromans; Adrian Muntean; Martin Lind; Mohammad Asadzadeh; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; reaction-diffusion-mechanics model; parameter delimitation; parabolic-pseudoparabolic equations; weak solvability; Rothe method; periodic homogenization; Matematik; Mathematics;

    Sammanfattning : In this thesis, parabolic-pseudoparabolic equations are derived coupling chemical reactions, diffusion, flow and mechanics in a heterogeneous medium using the framework of mixture theory. The weak solvability in 1-D of the obtained models is studied. LÄS MER

  5. 4. Impact Analysis : Organisational Views and Support Techniques

    Författare :Per Jönsson; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; impact analysis; roles; organisational levels; requirements engineering; imputation;

    Sammanfattning : Change is unavoidable in software development. During the entire lifecycle of a product, from concept to retirement, the environment changes; the needs of customers or the market change and grow, and with them the requirements on the system being developed. LÄS MER

  7. 5. Taxation of intermediate goods : a CGE analysis

    Författare :Lars Bohlin; Lars Hultkrantz; Mats Nilsson; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Optimal taxation; energy taxation; environmental taxes; emission trading; climate policy; carbon leakage; CGE-analysis; input-output tables; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Economics; Nationalekonomi; Economics; Nationalekonomi;

    Sammanfattning : This dissertation is concerned with tax rates for the use of commodities in general, and energy in particular. Computable General Equilibrium (CGE) models are used to analyze the normative question of whether the tax rate for intermediate use by firms should be the same as the tax rate for final consumption by households.
