  1. 1. Development of a geometallurgical framework for iron ores - A mineralogical approach to particle-based modeling

    Detta är en avhandling från Luleå University of Technology

    Författare :Mehdi Parian; Pertti Lamberg; Jan Rosenkranz; Hunt Julie; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometallurgy; process simulation; breakage characterization; ore texture; iron ore; modal mineralogy;

    Sammanfattning : The demands for efficient utilization of ore bodies and proper risk management in the mining industry have resulted in a new cross-disciplinary subject called geometallurgy. Geometallurgy connects geological, mineral processing and subsequent downstream processing information together to provide a comprehensive model to be used in production planning and management.

  2. 2. Characterization and densification of carbonized lignocellulosic biomass

    Detta är en avhandling från ; Department of Forest Biomaterials and Technology, Swedish University of Agricultural Sciences

    Författare :Magnus Rudolfsson; Sveriges lantbruksuniversitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis focuses on developing two main areas: characterization and densification of carbonized lignocellulosic biomass. Thermally treated biomass undergoes changes that enrich the content of carbon in the remaining solid fraction. LÄS MER

  3. 3. Identification and characterization of small molecules targeting MYC function

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Microbiology, Tumor and Cell Biology

    Författare :Qinzi Yan; Karolinska Institutet.; Karolinska Institutet.; [2019]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The MYC family genes (c-, N- and L-MYC) encode potent oncoproteins/transcription factors regulating fundamental cellular processes involved in cell proliferation, metabolism and survival, and they play an important role in tumor development. Overexpression of MYC often induce apoptosis as a failsafe mechanism to prevent tumor development and it is known to sensitize cells to genotoxic agents that induce DNA damage by triggered apoptosis.

  4. 4. Surface Integrity Characterization of Gears with respect to Running-in

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Microbiology, Tumor and Cell Biology

    Författare :Dinesh Mallipeddi; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; micropitting; surface asperities; running-in; surface roughness; residual stresses; Gears; surface chemistry;

    Sammanfattning : A gearbox with gears of different sizes is part of a vehicle transmission system that plays an important part in transmitting the engine power to the wheels. The efficient energy transmission highly relies on the performance of gears. Together, the mesh efficiency and durability determines the gear performance. LÄS MER

  5. 5. Characterization of nano-scale materials for interconnect and thermal dissipation application in electronics packaging

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Microbiology, Tumor and Cell Biology

    Författare :Xin Luo; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal conductivity; thermal interface material; thermal management; boron nitride fiber; electrospun nanofiber; lead-free solder; carbon fiber; nano-scale oxide layer; metal matrix composite;

    Sammanfattning : This thesis focuses on studies of nano-scale materials in electronic packaging applications with respect to following aspects: surface analysis of nano-scale oxide of lead-free solder particles, and thermal performance and mechanical property studies of nano-scale fiber and metal composite-based thermal interface materials. The composition and thickness of the solder oxide have a direct impact on the quality of interconnects and the reliability of a packaged system. LÄS MER
