Postural control was studied in 22 subjects with vestibular neruitis within 14 days after the onset of symptoms. Dynamic feed back control of posture were evaluated by analyzing the postural responses to vibration toward calf muscles applied according to a PRBS schedule. Properties of the dynamic control was normalized as swiftness, stiffness and damping of the responses. There was no prominent gr
The effects on wood of simultaneous mechanical and moisture loading are studied. In order to clarify the mechano-sorptive behaviour of wood, a review of different phenomena presented in the literature is included. Based on this review a constitutive model is proposed for the case of uniaxial stress in the longitudinal direction. The validity of the model is checked independently against test resul
Popular Abstract in Swedish Mekanisk ventilation kan medföra "ventilationsinducerad lungskada" (VILI), som kan öka sjuklighet och dödlighet i samband med akut lungskada (ALI). Flera ventilationssätt har föreslagits för att undvika VILI, men inte slutgiltigt utvärderats. En princip är att öka alveolär ventilation och CO2-elimination genom att minska ventilationen av de skadliga rummet, dead space. Ventilator-induced lung injury (VILI) may contribute to morbidity and mortality of acute lung injury (ALI). Lung protective ventilation (LPV), that reduces VILI, may involve low tidal volume (Vt). Particularly low Vt is possible if dead space ventilation is reduced e.g. by aspiration of dead space gas (ASPIDS). ASPIDS implies that gas rich in CO2 during expiration is aspirated through a separate c
The national QA system in Sweden does not any longer include assessment of the institutions’ internal QA procedures. The Experts Group on Quality at the Swedish Association for Higher Education (SHUF) has proposed and tested how voluntary audits can be performed by the institutions in collaboration, coordinated by SUHF. The audits have quality enhancement as its sole purpose. The audit method focu
The thesis discusses three morphosyntactic changes in Danish, Faroese, Norwegian, Swedish and English, namely the loss of morphological case, loss of V-to-I movement and the loss of stylistic fronting. The changes are observed on the basis of Icelandic which has kept all three characteristics. The hypothesis is that even though the loss of morphological case causes the loss of DAT-NOM constructio
