  1. 1. Investigating the parameters that influence the behaviour of natural iron ores during the iron production process

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Abraham Judah Bumalirivu Muwanguzi; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; natural iron ore; iron production; characterization; physical and metallurgical properties; sinter; pellet; direct reduction; low temperature degradation; sample weight; sample positioning; microstructure; reduction degree; solid conversion; Volumetric Model; Grain Model; Random Pore Model; Muko; Uganda;

    Abstract : In the iron production processes, sinters and pellets are mostly used as raw materials due to their consistency with respect to physical and chemical properties. However, natural iron ores, as mined, are rarely used directly as a feed material for iron processing. READ MORE

  2. 2. Acoustic Forces in Cytometry and Biomedical Applications: Multidimensional Acoustophoresis

    University dissertation from Department of Biomedical Engineering, Lund university

    Author : Carl Grenvall; Lund University.; Lunds universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustophoresis; Microfluidics; Ultrasound; Multinode; Cell Sorting; Particle Positioning; Cytometry; Lab-on-a-Chip; µTAS; Binary Separation; Acoustic Barriers; Acoustic Particle Manipulation; Acoustic Standing Waves; Blood Separation; Milk Analysis;

    Abstract : Over the last decades the ongoing work in the fields of Lab-on-a-Chip and Micro-Total-Analysis-Systems has led to the discovery of new or improved ways to handle and analyse small volumes of biofluids and complex biosuspensions. The benefits of working on the microscale include: miniaturization of the analysis systems with less need for large sample volumes; temporal and spatial control of suspended particle/cell positions; low volume sheath flow lamination or mixing; novel separation techniques by using forces inherent to the microscale domain; precise regulation of sample temperatures and rapid analysis with less volumes needed to be processed.

  3. 3. From Lab to Chip – and back Polymer microfluidic systems for sample handling in point-of-care diagnostics

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Jonas Hansson; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : This thesis contributes to the development of Lab-on-a-Chip systems that enables reliable, rapid medical diagnostics at the point-of-care. These contributions are focused on microfluidic Lab-on-a-Chip systems for sepsis diagnosis, autonomous sample-to-answer tests, and dried blood spot sampling. READ MORE

  4. 4. Detection and 3-D positioning of small defects using digital radiography, 3-D point reconstruction, and tracking

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Erik Lindgren; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pore Defects; Radiographic Testing; Nondestructive Evaluation; Laser Welded Titanium; Multiple Hypothesis Tracking; X-ray Testing;

    Abstract : The weight and quality concerned aero industry is constantly trying to decrease the excess material in their components. With decreased weight the fuel consumption can be lowered and the negative environmental effects from aviation decreased. READ MORE

  5. 5. Spleno-pancreatic development assessed by 3D molecular imaging

    University dissertation from Umeå : Umeå centrum för molekylär medicin (UCMM)

    Author : Amir Asayesh; Umeå universitet.; [2007]
    Keywords : Cell biology; Spleen; Pancreas; Imaging; Development; Cellbiologi; miljömedicinsk utvecklingsbiologi; Developmental Biology;

    Abstract : The development of different organs and tissues along the gastrointestinal tract, including the pancreas, depends on signalling between the endoderm and the adjacent mesenchyme. The Nkx gene Bapx1 is involved in spatial control of organ-positioning in the spleno-pancreatic region, and deficiency in this gene results in unacceptable proximity of the splenic mesenchyme to the pancreas.
