  2. 1. Development of characterisation methods for the components of the polymer electrolyte fuel cell

    Author : Jari Ihonen; KTH; []
    Keywords : polymer electrolyte membrane fuel cell; contacct resistance; clamping pressure; stainless steel; membrane degradation;

    Abstract : In this work characterisation methods and fuel cell hardwarewere developed for studying the components of the polymerelectrolyte fuel cell (PEFC). Humidifiers and other componentswere tested in order to develop reproducible and reliableexperimental techniques. A set-up for testing larger cells andstacks was developed. READ MORE

  5. 3. Spinal cord oxygenation during thoracic aortic clamping in pigs

    Author : Anders Hellberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Thoracoabdominal aortic replacement; spinal cord ischaemia; cerebrospinal; intrathecal monitoring; oxygen tension; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Abstract : Despite a dramatic reduction in the mortality associated with thoracoabdominal aorticreplacement during the past 40 years, spinal cord ischaemia that results in paraplegia remainsa serious complication. Simple and reliable intraoperative monitoring techniques are neededto detect impending neurological deficit in time to prevent permanent damage. READ MORE

  6. 4. Carotid Artery Stenosis : Surgical Aspects

    Author : Björn Kragsterman; Håkan Pärsson; David Bergqvist; Thomas Mätzsch; Uppsala universitet; []
    Keywords : Surgery; carotid endarterectomy; carotid artery stenosis; carotid clamping; cerebral ischaemia; Kirurgi;

    Abstract : Randomised controlled trials (RCT) have demonstrated a net benefit of carotid endarterectomy (CEA) in stroke prevention for patients with severe carotid artery stenosis as compared to best medical treatment. Results in routine clinical practice must not be inferior to those in the RCTs. READ MORE

  7. 5. The Ovulatory Process. Studies in the human and the rabbit

    Author : Pernilla Dahm-Kähler; Göteborgs universitet; []
    Keywords : ovulation; ovary; rabbit; human; follicle; MCP-1; intrafollicular pressure;

    Abstract : Background and general summary: Ovulation is the cascade of events ending with follicular rupture and oocyte extrusion. This ovulatory process is triggered by the LH surge, which induces biochemical and biophysical alterations within the preovulatory follicle. READ MORE
