  1. 31. A study of mold flux entrapment and gas entrainment in an ingot casting process

    Författare :Jun Yin; Mikael Ersson; Pär Jönsson; Yogeshwar Sahai; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mold flux entrapments; CFD; Gas entrainment; Ingot casting process; Uphill teeming process; Side teeming process; Numerical simulation; Non-metallic inclusions; Metallurgical process science; Metallurgisk processvetenskap; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : The focus of this work is to study the gas entrainment and mold flux entrapments during the ingot filling process based on physical and numerical modelling.The formation of the free surface was investigated in the uphill teeming method, which illustrates a dynamic change at a quasi-steady state.

  3. 32. Development Towards Sustainable Ironmaking : The IronArc Process

    Författare :Jonas Svantesson; Mikael Ersson; Robert Eriksson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IronArc; Refractory wear; plasma generator; freeze-lining; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The IronArc process is a novel process for a more sustainable production of liquid pig iron using electricity for heating and hydrocarbons for reduction. This thesis aims to facilitate its use by investigating possible refractory solutions and the gas blowing in the process which is done by a plasma generator. LÄS MER

  4. 33. The unemployment process : studies of search, selection, and social mobility in the labor market

    Författare :Tomas Korpi; Aage Sørensen; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociology; Sociologi; Sociology; sociologi;

    Sammanfattning : The purpose of this thesis is to examine some particular aspects of the unemployment process, the process by which the risk of unemployment is distributed within a population. This process can be partitioned into five distinct stages; the initiation of a "negative work career", entry into unemployment, the situation during unemployment, exit from unemployment, and finally the long-term consequences of unemployment for the employment situation of the individual.

  5. 34. Implementation of coordinated healthy lifestyle promotion in primary care : Process and outcomes

    Författare :Kristin Thomas; Preben Bendtsen; Barbro Krevers; Henna Hasson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background: Implementation of healthy lifestyle promotion in routine primary has been suboptimal. There is emerging evidence that coordinating care can improve the efficiency and quality of care. LÄS MER

  7. 35. Neighbors at Risk : A Quantitative Study of Civil War Contagion

    Författare :Erika Forsberg; Mats Hammarström; Håvard Hegre; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; conflict contagion; internationalization of conflict; civil war; ethnic conflict; transnational ethnic groups; ethnic polarization; refugee flows; domino effects; Peace and conflict research; Freds- och konfliktforskning; Peace and Conflict Research; freds- och konfliktforskning;

    Sammanfattning : While previous research shows that civil wars can spread to neighboring states, we do not know why certain neighbors are more at risk than others. To address this research gap, this dissertation proposes a contagion process approach that can identify the most likely targets of contagion effects from an ongoing conflict. LÄS MER
