1. 1. Intraocular pressure : clinical aspects and new measurement methods

   Författare :Gauti Jóhannesson; Christina Lindén; Per Hallberg; Anders Eklund; Boel Bengtsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intraocular pressure; glaucoma; tonometry; ISO; LASEK; CCT; curvature; Ophtalmiatrics; Oftalmiatrik; Ophtalmology; oftalmiatrik;

   Sammanfattning : Intraocular pressure (IOP) measurement is a routine procedure and a fundament in glaucoma care. Elevated IOP is the main risk factor for glaucoma, and to date, reduction of IOP is the only possible treatment. In a retrospective clinical material, the prevalence of open angle glaucoma was estimated on the west coast of Iceland. LÄS MER

3. 2. Putting the Singing Voice on the Map : Towards Improving the Quantitative Evaluation of Voice Status in Professional Female Singers

   Författare :Anick Lamarche; Sten Ternström; Thomas Cleveland; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Voice Range Profile-Phonetogram-Singing voice-Performance-Clinical assessment-health-voice disorder-self-perception-proprioceptive feedback; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Sammanfattning : Diagnostic and evaluative methods used in voice care are mostly designedfor the speaking voice, and are not necessarily directly applicable to thesinging voice. This thesis investigated the possibilities of fine tuning, improvingand quantifying the voice status assessment of the singer, focusingespecially on the Western operatic female voice. LÄS MER

4. 3. Head Injuries in Car-to-Pedestrian Accidents - Investigation of Head Impact Dynamics, Injury Mechanisms and Countermeasures

   Författare :Jianfeng Yao; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; accident analysis; head injury; head protection; mathematical simulation; accident reconstruction; injury mechanism; Pedestrian accident;

   Sammanfattning : The aim of this study was to investigate head impact dynamics and to establish risk functions for head injuries by mathematical reconstructions of real-world car-to-pedestrian accidents. Furthermore, an attempt was made to develop an approach for the design and evaluation of head-protective devices. LÄS MER

5. 4. Development of the pressure-time method: final integration point and head losses

   Författare :Mehrdad Kalantar Neyestanaki; Michel Cervantes; Jonathan Nicolle; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pressure-time method; head loss calculation; endpoint determination; Strömningslära; Fluid Mechanics;

   Sammanfattning : Hydropower is an efficient renewable energy source able to regulate electrical grid fluctuations. However, many hydropower plants were built decades ago, and now it is the time for a major refurbishment. The turbine's efficiency is essential and needs to be determined before and after refurbishment. LÄS MER

7. 5. Severe Head Injury. Evaluation of Acute Treatment and Rehabilitation

   Författare :Christer Eker; Neurokirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; neuropsykologi; neurofysiologi; cerebral blood flow; neuropsychological test; assessment of motor and process skills; rehabilitation; Neurology; neuropsychology; neurophysiology; intracranial pressure; Severe head injury; intensive care;

   Sammanfattning : Mortality after severe head injury can be considerably reduce with a therapy using physiological principles for brain volume regulation and preserved microcirculation, with the main purpose of restricting the rise in ICP to reasonable levels simultaneously with preservation of adequate blood supply. This study shows that the ?Lund Concept? can reduce mortality in patients with severe traumatic brain lesions from 47% to 8%. LÄS MER
