2. 1. PHYSIOLOGICAL AND BIOMECHANICAL FACTORS DETERMINING CROSS-COUNTRY SKIING PERFORMANCE

   Author : Erik Andersson; Hans-Christer Holmberg; Glenn Björklund; Thomas Stöggl; Jos J. de Koning; Mittuniversitetet; []
   Keywords : cycle characteristics; energy cost; energy yield; incline; joint angles; kinematics; kinetics; mechanics; Nordic skiing; oxygen deficit; oxygen demand; technique transitions; total metabolic rate.;

   Abstract : Cross-country (c.c.) skiing is a complex sport discipline from both physiological and biomechanical perspectives, with varying course topographies that require different proportions of the involved sub-techniques to be utilised. A relatively new event in c. READ MORE

4. 2. Detection and haemodilutive treatment of cerebral arterial vasospasm and delayed ischaemia after Aneurysmal Subarachnoid Haemorrhage

   Author : Anders Ekelund; Neurokirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral oxygen delivery.; cerebral blood flow; hypervolaemic haemodilution; isovolaemic haemodilution; transcranial cerebral oximetry; transcranial Doppler ultrasound; delayed ischaemic deficit; Aneurysmal subarachnoid haemorrhage; cerebral arterial vasospasm; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

   Abstract : This thesis deals with cerebral arterial vasospasm and ischaemia, a serious complication after aneurysmal subarachnoid haemorrhage. Firstly is the noninvasive transcranial Doppler ultrasound and transcranial cerebral oximetry techniques evaluated in detecting cerebral arterial vasospasm in clinical practice. READ MORE

5. 3. Radiative transfer in the absorption bands of oxygen : Studies of their significance in ozone chemistry and potential for aerosol remote sensing

   Author : Gijs Koppers; Knut Stamnes; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Meteorology; Meteorologi; meteorologi; Meteorology;

   Abstract : Among the scientific topics of greatest public interest are the ozone question and climatic change. The discovery of the Antarctic ozone hole in 1985 and recognition of large scale ozone depletions in the northern hemisphere focused the world's attention on human induced changes in the atmosphere.

6. 4. 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

7. 5. On the pathophysiology of idiopathic adult hydrosephalus syndrome : energy metabolism, protein patterns, and intracranial pressure

   Author : Aina Ågren Wilsson; Per Enblad; Umeå universitet; []
   Keywords : hydrocephalus; biochemical markers; microdialysis; cerebrospinal fluid; B waves; brain tissue oxygen tension; Neurology; neurologi;

   Abstract : The symptoms in Idiopathic Adult Hydrocephalus Syndrome (IAHS) – gait disturbance, incontinence, and cognitive deficit – correlate anatomically to neuronal dysfunction in periventricular white matter. The pathophysiology is considered to include a cerebrospinal fluid (CSF) hydrodynamic disturbance, including pressure oscillations (“B waves”), in combination with cerebrovascular disease. READ MORE
