  1. 1. Empirical Essays on Health and Human Capital

    Författare :Thomas Fast; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Labor Economics; Health Economics; Education; Retirement; Pharmaceuticals; Econometric Analysis;

    Sammanfattning : This thesis includes one introductory chapter and three independent papers. The first paper adds to the broad literature regarding the effect of alcohol consumption on educational attainment. LÄS MER

  3. 2. Fast Numerical Techniques for Electromagnetic Problems in Frequency Domain

    Författare :Martin Nilsson; Per Lötstedt; Abderrahmane Bendali; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fast Multipole Method; Minimal Residual Interpolation; Sparse Approximate Inverse preconditioning; Method of Moments; fast solvers; iterative methods; multiple right-hand sides; error analysis; Numerical Analysis; Numerisk analys;

    Sammanfattning : The Method of Moments is a numerical technique for solving electromagnetic problems with integral equations. The method discretizes a surface in three dimensions, which reduces the dimension of the problem with one. A drawback of the method is that it yields a dense system of linear equations. LÄS MER

  4. 3. Inductively Coupled Plasma Atomic Emission Spectrometry : Exploring the Limits of Different Sample Preparation Strategies

    Författare :Barbro Kollander; Jean Pettersson; Marit Andersson; Jonas Bergquist; Grethe Wibetoe; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multi element analysis; trace element; ICP-AES; inductively coupled plasma atomic emission spectromtery; water analysis; liver analysis; non digested samples; medical samples; biological samples; samples from biopsies and autopsies; mice organ; fast analysis; internal standard; preconcentration; matrix elimination; Cu; Zn; Mn; Co; Pb; Cd; Mg; Ca; Fe; Ni; Cr; S; P; K; Al; Analytical chemistry; Analytisk kemi; Analytical Chemistry; Analytisk kemi;

    Sammanfattning : This thesis describes two different sample preparation strategies for inductively coupled plasma atomic emission spectrometry (ICP-AES), and their ability regarding multi element quantification in complex samples. Sensitivity, repeatability, reproducibility and accuracy were investigated. LÄS MER

  5. 4. Mediated Europes : Discourse and Power in Ukraine, Russia and Poland During Euromaidan

    Författare :Roman Horbyk; Johan Fornäs; Patrik Åker; Sabina Mihelj; Södertörns högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; media; discourse; power; postcolonial theory; foreign policy; journalists; politicians; Europe; Ukraine; Russia; Poland; Euromaidan; медії; дискурс; влада; зовнішня політика; журналісти; політики; Европа; Україна; Росія; Евромайдан; medier; diskurs; makt; utrikespolitik; journalister; politiker; Europa; Ukraina; Ryssland; Polen; Euromajdan; Kritisk kulturteori; Critical and Cultural Theory; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : This study focuses on mediated representations of Europe during Euromaidan and the subsequent Ukraine–Russia crisis, analysing empirical material from Ukraine, Poland and Russia. The material includes articles from nine newspapers, diverse in terms of political and journalistic orientation, as well as interviews with journalists, foreign policymakers and experts, drawing also on relevant policy documents as well as online and historical sources.

  7. 5. Homogenization of reaction-diffusion problems with nonlinear drift in thin structures

    Författare :Vishnu Raveendran; Adrian Muntean; Emilio N.M. Cirillo; Claudia Timofte; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Thin layer; homogenization; dimension reduction; reaction-diffusion-convection problem; two-scale convergence; effective transmission condition; fast drift; weak solvability of quasi-linear parabolic systems in unbounded domains.; Matematik; Mathematics;

    Sammanfattning : We study the question of periodic homogenization of a variably scaled reaction-diffusion equation with non-linear drift of polynomial type. The non-linear drift was derived as hydrodynamic limit of a totally asymmetric simple exclusion process (TASEP) for a population of interacting particles crossing a domain with obstacle. LÄS MER
