    Sammanfattning : Carcinoma of the cervix is a global problem. Brachytherapy (BT) is one of the mainradiation therapy components used in the management of cervical cancer. LÄS MER

  3. 2. Pathophysiology of subarachnoid hemorrhage in the rat

    Författare :Giselle F Prunell dos Santos; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Apoptosis; cell death; cerebral blood flow; cerebral metabolism; inflammation; NMDA receptor subunits; subarachnoid hemorrhage.;

    Sammanfattning : Subarachnoid hemorrhage (SAH) causes brain damage, but the underlying mechanisms are poorly understood. An obstacle in SAH research is the lack of an adequate animal model. In this thesis, we developed a new approach to simulate SAH that involves the injection of blood into the prechiasmatic cistern of the rat. LÄS MER

  4. 3. Continuous Finding Problems and Implementing Solutions in Health Care-Associated Infections : The Role of Infection Preventionists

    Författare :Luís Fernando Irgang dos Santos; Magnus Holmén; Gerson Tontini; Fábio Gama; James Barlow; Högskolan i Halmstad; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Health Care-Associated Infections; Infection Prevention and Control; Infection Preventionists; Problem-Finding and Problem-Solving Perspective; Implementation of Changes;

    Sammanfattning : This licentiate thesis aims to understand how infection preventionists (IPs) continuously find problems and implement solutions related to health care-associated infections (HAIs) in hospital settings.HAIs are infections acquired by patients during the process of care and are among the main causes of deaths worldwide.

  5. 4. Feedback Control of Robotic Friction Stir Welding

    Författare :Jeroen De Backer; Gunnar Bolmsjö; Anna-Karin Christiansson; Jorge Dos Santos; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction stir welding; Process automation; Temperature control; Force control; Deflection model; Robotics; Svetsning; FSW; processtyrning; temperaturstyrning; robot; utböjning; kraftstyrning; Industriell arbetsvetenskap; Industrial engineering; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : The Friction Stir Welding (FSW) process has been under constant developmentsince its invention, more than 20 years ago. Whereas most industrial applicationsuse a gantry machine to weld linear joints, there are applications which consistof complex three-dimensional joints, requiring more degrees of freedom fromthe machines.
