  1. 6. Effects of confinement and initiation delay on fragmentation and waste rock compaction : Results from small scale tests

    Författare :Daniel Johansson; Gideon Chitombo; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Sammanfattning : Sub-level caving (SLC) is classified as a mass mining method and there is an increasing interest in its application worldwide and in a very wide range of geotechnical environments. Design of sub-level blasting rounds and optimization has become more important now when the sizes of the blasting rings have become larger. LÄS MER

  3. 7. Fragmentation and waste rock compaction in small-scale confined blasting

    Författare :Daniel Johansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : Sub-level caving (SLC) is an important mass mining method, used at LKAB e.g. The caved rock or debris at the SLC interface reduces the fragmentation and the swelling of the blasted ring and it dissipates the explosive energy. These phenomena may immobilize the blasted ring, causing ore losses. LÄS MER

  4. 8. Impact of cereal food structures on metabolic effects and satiety : the role of processing and product formulation

    Författare :Daniel Johansson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Insulin resistance, high blood glucose and raised total blood cholesterol are major risk factors for cardiovascular disease and type 2 diabetes. Partly they are caused by overweight and obesity. Diet is an important modifiable determinant for these risk factors and understanding how food characteristics, e.g. LÄS MER

  7. 10. Convergence in mixed reality-virtuality environments : facilitating natural user behavior

    Författare :Daniel Johansson; Leo J. de Vin; Morten Fjeld; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mixed reality. augmented reality; augmented virtuality; head mounted display; omnidirectional floor; natural interface; telepresence; Datalogi; Computer and Systems Science;

    Sammanfattning : This thesis addresses the subject of converging real and virtual environments to a combined entity that can facilitate physiologically complying interfaces for the purpose of training. Based on the mobility and physiological demands of dismounted soldiers, the base assumption is that greater immersion means better learning and potentially higher training transfer. LÄS MER
