2. 1. Pressure sores : risk assessment and prevention

   Author : Margareta Lindgren; Christina Lindholm; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : 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.

4. 2. Influence of total pressure on complete oxidation of methane over Pd/Al2O3 catalysts

   Author : Carl-Robert Florén; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pd Al2O3; methane oxidation; multiscale flow-reactor model; total pressure;

   Abstract : Natural gas and biogas, which have methane as their main component, are interesting choices of fuel to reduce the anthropogenic emissions of greenhouse gases. However, as methane is a greenhouse gas, uncombusted methane should be removed from the combustion gases. Emission control catalysts can preferably be used to completely oxidise methane. READ MORE

5. 3. Negative Pressure Wound Therapy - Effects on Sternotomy Wounds and the Intrathoracic Organs

   Author : Christian Torbrand; Lund Oftalmologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NPWT; negative pressure; vacuum-assisted closure; sternotomy wounds; deep sternal wound infection; mediastinitis; thoracic surgery; pressure transduction; neurohormones; neuropeptides; total heart volume variation; cardiac output; wound contraction; macrodeformation;

   Abstract : Negative pressure wound therapy (NPWT) has been widely adopted for the treatment of deep sternal wound infections due to its excellent clinical outcome. However, the mechanisms of action and effects on hemodynamics have not been thoroughly elucidated. READ MORE

6. 4. Miniaturized fluid system for high-pressure analytics

   Author : Simon Södergren; Klas Hjort; Sami Franssila; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-pressure; Microfluidics; Thermal regulation; Fluid mechanics; In-situ sensors; High-pressure analytics; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

   Abstract : High-pressure chemistry can be used to determine the contents of blood or water samples and to discover new chemistries. However, working with chemistry at pressures of many tens, or even hundreds, of bars often requires expensive and stationary equipment, such as autoclaves or chromatographic systems like high-performance liquid chromatography (HPLC).

7. 5. Myocardial Topical Negative Pressure

   Author : Sandra Lindstedt Ingemansson; Thoraxkirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; coronary blood flow; microvascular blood flow; topical negative pressure TNP ;

   Abstract : The aim of this research was to find out if it is possible to increase myocardial microvasular blood flow by applying a topical negative pressure source directly onto the myocardium. Topical negative pressure is a relatively new wound healing technique. READ MORE
