  1. 1. Exploiting reciprocal space : Electron diffraction, textures and precession

    Författare :Peter Oleynikov; Sven Hovmöller; Xiaodong Zou; Jean-Paul Morniroli; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; electron diffraction; texture patterns; precession electron diffraction; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : Electron crystallography emerges as a new tool for accurate structure determination of very small crystals. In order to exploit the full potential of electron diffraction, the methods for data acquisition and processing have to be developed towards the high standards of X-ray crystallography. LÄS MER

  2. 2. Efficient mineral liberation – Multidimensional investigation of mechanical stress and ore texture

    Författare :Parisa Semsari Parapari; Jan Rosenkranz; Mehdi Parian; Hakan Benzer; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Loading mechanism; Ore texture; Breakage mode; Fracture energy; Fragmentation; Breakage mechanism; Statistical analysis; 3D Deformation; Crack quantification; Mineral Processing; Mineralteknik;

    Sammanfattning : Within mineral comminution, the product properties (such as particle size distribution and mineral liberation characteristics) along with process efficiency are affected by material related and process environment factors. Understanding and optimizing these factors leads to designing and developing an energy-efficient process with a specified product. LÄS MER

  3. 3. Development of a geometallurgical testing framework for ore grinding and liberation properties

    Författare :Abdul-Rahaman Mwanga; Jan Rosenkranz; Hakan Benzer; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grindability test; mineral texture; breakage properties; mineral liberation; process modeling; geometallurgy; Mineral Processing; Mineralteknik;

    Sammanfattning : Efficient measurement methods for comminution properties are an important prerequisite for testing the variability of an ore deposit within the geometallurgical context. This involves the investigation of effects of mineralogy and mineral texture on the breakage of mineral particles. LÄS MER

  4. 4. Rye bread in Sweden : Health-related and sensory qualities, consumer perceptions and consumption patterns

    Författare :Pernilla Sandvik; Margaretha Nydahl; Iwona Kihlberg; Ingela Marklinder; Hely Tuorila; Uppsala universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; national dietary survey; sensory analysis; preference mapping; sourdough; whole grain; public health; health promotion; Kostvetenskap; Food; Nutrition and Dietetics;

    Sammanfattning : Rye bread has shown potential as a health-beneficial component in the diet, especially in relation to non-communicable diseases. To have a beneficial effect in reality, however, it also needs to be available, chosen and eaten. Less research has focused on rye bread from a consumer perspective. LÄS MER

  5. 5. On the bone response to different implant textures. A 3D analysis of roughness, wavelength and surface pattern of experimental implants

    Författare :Carin Hallgren Höstner; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surface modification; surface texture; roughness; surface evaluation; in vivo studies.;

    Sammanfattning : PurposeThe purpose of the present thesis was to investigate the bone response to different isotropic, anisotropic and organised surface patterns.Material and methodsImplant surfaces have been modified with different techniques (abrasive blasting, turning, milling, photolithography or laser ablation).
