1. 1. Gas Embolism in Laparoscopic Liver Surgery

   Författare :Diddi Fors; Sten Rubertsson; Dag Arvidsson; Tor Inge Tønnessen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gas embolism; laparoscopic liver; CVP; PEEP; high frequency jet ventilation; cardiopulmonary physiology; carbon dioxide; Anaesthesiology and Intensive Care; Anestesiologi och intensivvård;

   Sammanfattning : Laparoscopic liver surgery is complicated due to the structure of this organ with open sinusoids. A serious disadvantage is the risk of gas embolism (GE) due to CO2 pneumoperitoneum. CO2 can enter the vascular system through a wounded vein. A common opinion is that gas fluxes along a pressure gradient, e. LÄS MER

3. 2. Flow Measuring Techniques in Steady and Pulsating Compressible Flows

   Sammanfattning : This thesis deals with flow measuring techniques applied on steady and pulsatingflows. Specifically, it is focused on gas flows where density changes canbe significant, i.e. compressible flows. LÄS MER

4. 3. The chemistry of organic iodides under severe nuclear accident conditions in LWRs

   Författare :Sabrina Tietze; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic iodides; Wet-filter system scrubber ; Chlorine; Volatile iodine source term; Severe nuclear accident; Cables; Sorption; Containment; Paint; Iodine; LWR; Radiolysis;

   Sammanfattning : For many countries nuclear fission is an important part of their energy portfolio. However, a great concern is the occurrence of nuclear reactor accidents, which can result in the emission of radioactivity into the environment. LÄS MER
