  1. 1. Modeling adsorption of organic compounds on activated carbon : a multivariate approach

    Författare :Jufang Wu; Anders Cedergren; Ingrid Fängmark; Ola Claesson; Lars-Gunnar Hammarström; Fritz Stoeckli; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; activated carbon; adsorption; adsorption capacity; adsorption rate; PCA; PLS; binary mixtures; Dubinin-Radushkevich; Wheeler-Jonas; Analytisk kemi; Analytical chemistry; Analytisk kemi; analytisk kemi; Analytical Chemistry;

    Sammanfattning : Activated carbon is an adsorbent that is commonly used for removing organic contaminants from air due to its abundant pores and large internal surface area. This thesis is concerned with the static adsorption capacity and adsorption kinetics for single and binary organic compounds on different types of activated carbon. LÄS MER

  2. 2. Mesoscopic superconductivity : quasiclassical approach

    Författare :Marek Ožana; Andrei Shelankov; Dierk Rainer; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; mesoscopic superconductivity; quasiclassical theory; boundary conditions; multi-layer structures; Gor kov equations; quasiclassical Green s function; Green s function on classical trajectories;

    Sammanfattning : This Thesis is concerned with the quasiclassical theory of meso-scopic superconductivity. The aim of the Thesis is to introduce the boundary conditions for a quasiclassical Green’s function on partially transparent interfaces in mesoscopic superconducting structures and to analyze the range of applicability of the quasiclassical theory.

  3. 3. From Cost Accounting to Customer Accounting in the HospitalityIndustry : a Constructive Approach

    Författare :Mats Carlbäck; Sweden Göteborg Handelshögskolan Göteborgs universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Restaurant Industry; Management Accounting Tools; Management Control; Experience Accounting; FAMM; Cost Allocation; Performance Measurement; Constructive Approach;

    Sammanfattning :  The objective of this research project is to analyse and identify the role of tools used in the restaurant industry to improve resource management efficiency and performance, to develop and test the Experience Accounting tool, and to test and evaluate if this particular system is the system that could fill a gap in the hospitality industry.The research is based on the notion that the hospitality business is part of the experience industry and is producing experiences rather than a plate of food and a bed to sleep in.

  4. 4. Modelling the dynamics of domestic low-temperature heat pump heating systems for improved performance and thermal comfort : a systems approach

    Författare :Dimitra Sakellari; Per Lundqvist; Savvas Tassou; KTH; []
    Nyckelord :Technology; heat pump; domestic heating and ventilation; low-temperature hydronic heat distribution; systems approach; integration; simulation; energy efficiency; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The present environmental concerns and the rising human requirement for solutions with better comfort and lower costs have resulted in an increased awareness for the energy use in the built environment. Technical advances in building structural systems and materials, heating and other comfort-providing systems and controlling strategies all lead to the integration of building technology with the function of buildings and the aesthetics.

  5. 5. Understanding Comorbid Pain and Emotions : A transdiagnostic approach

    Författare :Matilda Wurm; Katja Boersma; Maria Tillfors; Mark A. Lumley; Örebro universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Transdiagnostic approach; musculoskeletal pain; emotions; comorbidity; shared vulnerability model; social factors; gender;

    Sammanfattning : Experiencing pain, including an emotional reaction, is part of being hu­man. Emotional comorbidity is common in pain patients, and corre­lated to higher symptomatology and worse treatment outcome. The shared vulnerability model suggests that many vulnerability and main­taining factors may be involved in both pain and emotional problems. LÄS MER
