1. 1. Pressure sores : risk assessment and prevention

   Författare :Margareta Lindgren; Christina Lindholm; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : The aims of this thesis were to study the prevalence, incidence, prevention and treatment of pressure sores, to further develop a risk assessment scale, and test the reliability and validity of this scale, to identify risk factors for pressure sore development, and to study skin blood flow in non-blanchable erythema areas as compared to undamaged skin.Criteria used for pressure sore assessment were persistent discoloration i.

3. 2. Advanced MEMS Pressure Sensors Operating in Fluids

   Författare :Emil Anderås; Ventsislav Yantchev; Ilia Katardjiev; Jörgen Olsson; Enrico Verona; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pressure sensor; piezoresistance; nanofilms; AlN; microacoustic; Lamb wave; thin film; resonator; sensitivity; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Sammanfattning : Today’s MEMS technology allows manufacturing of miniaturized, low power sensors that sometimes exceeds the performance of conventional sensors. The pressure sensor market today is dominated by MEMS pressure sensors.In this thesis two different pressure sensor techniques are studied. LÄS MER

4. 3. Clinical Electrocochleography in Menière´s disease

   Författare :Kornel Sass; Lund Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intrathoracic pressure; perilymphatic fistula; pressure exposure; endolymphatic hydrops; Menière´s disease; reproducibility; specificity; sensitivity; rarefaction click; condensation click; electrocochleography; summating potential; Otorhinolaryngology; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen;

   Sammanfattning : Electrocochleography (ECoG) is an objective method to evaluate cochlear electrophysiology. The recordings are considered to reflect the mechano-electric processes of the cochlea, and can indicate the presence of suspected endolymphatic hydrops. LÄS MER

5. 4. Pulse-Synchronous Intramuscular Pressure Oscillations

   Författare :Andreas Nilsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; compartment syndrome; chronic anterior compartment syndrome; intramuscular pressure; pulse-synchronous oscillations in intramuscular pressure; ; intramuscular arterial pulsations; fiber-optic technique;

   Sammanfattning : Background Intramuscular pressure (IMP) is measured in studies of tissue nutrition and in the diagnosis of compartment syndromes. Patients with compartment syndromes have an elevated IMP due to increased volume in a muscle compartment. LÄS MER

7. 5. A sensitivity analysis of the Winter-Kennedy method

   Författare :Binaya Baidar; Michel J. Cervantes; Mikael Sendelius; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydropower; discharge; Winter-Kennedy; CFD; Sensitivity; Strömningslära; Fluid Mechanics;

   Sammanfattning : Hydropower is among the lowest-cost electrical energy sources due to its long lifespan and lower operation and maintenance cost. The hydro-mechanical components of hydropower plants generally last about four to five decades, then they are either overhauled or replaced. LÄS MER
