  4. 4. Toughness of Tool Steel

    University dissertation from Uppsala : Institutionen för teknikvetenskaper

    Author : Henrik Jesperson; Uppsala universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Toughness; Tool Steel; Heat Treatment; Temperature; Energy absorption; Impact Testing; Fracture Toughness Testing; Non-metallic Inclusions; Carbides; Nitrides; Statistics; TECHNOLOGY; TEKNIKVETENSKAP; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : Toughness is the ability to resist tensile stresses in the presence of a notch or crack. Sometimes gross cracking of industrial tools, mould or dies, occurs due to insufficient toughness. As the economic consequences of the gross cracking are serious, the toughness of industrial tool material, generally tool steel, is of paramount importance. READ MORE

  5. 5. Significance of Human Papillomavirus (HPV) Analysis for the Detection of Precancerous Cervical Lesions Impact of Self Sampling

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Karin Sanner; Uppsala universitet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human papilloma virus; HPV; self-sampling; organized screening; cervical cancer screening; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Abstract : Cervical cancer is the second most common cancer, with about 500 000 new cases per year among women worldwide. With a well-organized screening programme the number of cases can be reduced by more than 50%. In spite of having such a screening programme there are still around 450 new cases yearly in Sweden.
