1. 6. The safety relevance of standardized tests for diving equipment

   Författare :Mårten Silvanius; Oskar Frånberg; Greg Murphy; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diving; rebreather; underwater breathing apparatus; unmanned testing; hyperbaric; scuba; oxygen sensor; composite gas cylinder; carbon dioxide monitoring;

   Sammanfattning : Vital components are more or less prone to fail in a diving apparatus. This thesis examines the performance of oxygen sensors, carbon dioxide scrubber monitoring and composite gas cylinders. LÄS MER

3. 7. Hypoxic Blackout in Serial Freediving – Protective Mechanisms and Risk Factors

   Författare :Frank Pernett; Erika Schagatay; Glenn Björklund; Anton Westman; Mittuniversitetet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; breath-hold diving; diving response; hyperventilation; hypoxia; oxygen saturation; oxygen stores; pulse oximetry; sonography; splenic contraction.;

   Sammanfattning : Breath-hold diving or freediving exposes the body to stressors such as low oxygen and high carbon dioxide levels in the blood, increased hydrostatic pressure, and cold. The reduction in blood oxygen levels is considered a primary factor for loss of consciousness while diving. This is known as hypoxic blackout. LÄS MER

4. 8. Reactive Sputter Deposition of Functional Thin Films

7. 10. Chemical Vapour Deposition of Undoped and Oxygen Doped Copper (I) Nitride

   Författare :Anna Fallberg; Jan-Otto Carlsson; Mikael Ottosson; Kwang-Leong Choy; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemical vapour deposition; copper hexafluoroacetylacetonate; copper I nitride; copper I oxide; multilayers; oxygen doping; Organic chemistry; Organisk kemi; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : In science and technology there is a steadily increased demand of new materials and new materials production processes since they create new application areas as well as improved production technology and economy. This thesis includes development and studies of a chemical vapour deposition (CVD) process for growth of thin films of the metastable material copper nitride, Cu3N, which is a semiconductor and decomposes at around 300 oC.
