  1. 1. Sharing Good Examples, Then What? Investigations of Contingency and Continuity in the Scaling-of-ESD-Activities-as-Learning

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Martin Mickelsson; David Kronlid; Anna Danielsson; Rob O’Donoghue; [2020]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sustainable development; environmental and sustainability education; scaling; scaling-up; implementation gap; learning; Curriculum Studies; Didaktik;

    Abstract : This thesis aims to contribute to a deepened and nuanced understanding of scaling in environmental and sustainability education (ESE) research, specifically, to develop a conceptual framework for engaging with issues of scaling in policy and practice regarding education for sustainable development (ESD). Three research objectives are formulated. READ MORE

  2. 2. Sodium Salt Scaling in Black Liquor Evaporators

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mathias Gourdon; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sodium carbonate; black liquor; falling film evaporation; fouling; scaling; heat transfer; sodium sulfate;

    Abstract : Sodium salt scaling has long been recognized as a problem in the recovery cycle of kraft pulp mills, especially in black liquor evaporators. In the black liquor evaporation, as the black liquor becomes more concentrated, the sodium salts, particularly sodium carbonate and sodium sulfate, will saturate and precipitate from the solution.

  3. 3. Topological and Scaling Analysis of Geospatial Big Data

    University dissertation from Gävle : Gävle University Press

    Author : Ding Ma; Högskolan i Gävle.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Third definition of fractal; scaling; topology; power law; head tail breaks; ht-index; complex network; geospatial big data; natural cities; natural streets;

    Abstract : Geographic information science and systems face challenges related to understanding the instinctive heterogeneity of geographic space, since conventional geospatial analysis is mainly founded on Euclidean geometry and Gaussian statistics. This thesis adopts a new paradigm, based on fractal geometry and Paretian statistics for geospatial analysis. READ MORE

  4. 4. Black Liquor Scaling Propensity - Experimental Investigation in a Pilot Evaporator

    University dissertation from Gävle : Gävle University Press

    Author : Mathias Gourdon; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sodium carbonate; fouling; sodium sulphate; black liquor; incrustation; scaling; evaporation; falling film; evaporator; encrustation; kraft black liquor;

    Abstract : Scaling in the recovery cycle of kraft pulp mills has long been recognised as a problem, especially in black liquor evaporators. Most problems are connected with the precipitation of sodium salts. READ MORE

  5. 5. Scaling techniques using CFD and wind tunnel measurements for use in aircraft design

    University dissertation from Stockholm : KTH

    Author : Karl Pettersson; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; wind tunnel; scaling; Reynolds number effect; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik;

    Abstract : This thesis deals with the problems of scaling aerodynamic data from wind tunnel conditions to free flight. The main challenges when this scaling should be performed is how the model support, wall interference and the potentially lower Reynolds number in the wind tunnel should be corrected. READ MORE
