  1. 16. Acute skeletal muscle ischemia and reperfusion in the rat : The role of leukocytes and the effect of hyperbaric oxygen on microcirculation and metabolism during reperfusion

    Författare :Allan Sirsjö; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Much experimental work in recent years seems to indicate that reperfusion after long periods of ischemia can damage tissue. Suggested factors of importance are accumulation of polymorphonuclear leukocytes (PMNs) and production of reactive oxygen metabolites (ROMs). LÄS MER

  3. 17. Titanium oxide nanoparticle production using high power pulsed plasmas

    Författare :Rickard Gunnarsson; Ulf Helmersson; Grzegorz Greczynski; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis covers fundamental aspects of process control when growing titanium oxide nanoparticles in a reactive sputtering process. It covers the influence of oxygen containing gas on the oxidation state of the cathode from which the growth material is ejected, as well as its influence on the particles oxidation state and their nucleation.

  4. 18. The process atmosphere as a parameter in the Laser-Powder Bed Fusion process

    Författare :Camille Nicole Géraldine Pauzon; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process stability; 316L stainless steel; Ti-6Al-4V; Laser-Powder Bed Fusion; processing atmosphere; process control; powder degradation; Additive Manufacturing;

    Sammanfattning : Laser-Powder Bed Fusion (L-PBF) is an Additive Manufacturing (AM) technique that allows to produce near-net shape components of complex design. Applied to metallic materials, L-PBF allows to consolidate subsequent layers of powder using the heat from laser radiation. LÄS MER

  5. 19. Controlling the growth of nanoparticles produced in a high power pulsed plasma

    Författare :Rickard Gunnarsson; Ulf Helmersson; Nils Brenning; Holger Kersten; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Nanotechnology can profoundly benefit our health, environment and everyday life. In order to make this a reality, both technological and theoretical advancements of the nanomaterial synthesis methods are needed. LÄS MER

  7. 20. Aspects of recovery following day care anaesthesia : A clinical and experimental study

    Författare :Anil Gupta; Kari Korttila; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : A new test for the assessment of psychomotor recovery - the perceptive accuracy test - was designed and tested in a group of volunteers. It was found to be reproducible and not associated with any significant learning. LÄS MER
