  1. 1. Redox Regulation and Stress Responses - Studies in Bacillus subtilis

    Författare :Jonas Larsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; redox sensor; oxygen sensor; reactive nitrogen species; RNS; Biology; Biologi; Microbiology; bacteriology; virology; mycology; bakteriologi; Mikrobiologi; virologi; mykologi; Bacillus subtilis; Rex; yjbI; ydiH; yjbH; redox regulation;

    Sammanfattning : Redox reactions are central to all organisms to sustain life. Both anabolic and catabolic metabolism depends on them. It is thus vital to sense and adjust the redox balance in the cell. One major factor affecting the redox status is the level of oxygen present. LÄS MER

  3. 2. Development and use of an optical pCO2 sensor in marine studies

    Författare :Dariia Atamanchuk; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pCO2; O2; sensor; optode; cross-sensitivity; carbonate system of seawater; biogeochemistry; Redfield ratio; the Koljo Fjord; cabled observatory; CCS; QICS; environmental engineering; leakage detection; MVDA; DoE;

    Sammanfattning : Partial pressure of CO2 (pCO2) is one of the most important parameters, which are measured in the global ocean in conjunction with ocean acidification studies. It is also a parameter of great interest to aquaculture and fish industries since CO2 in large amounts is highly toxic for animals. The requirements for pCO2 measuring systems, e.g. LÄS MER

  4. 3. Surviving under water : Physiological limitations and technical possibilities

    Författare :Mårten Silvanius; Oskar Frånberg; Rachel Lance; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diving; diving apparatus; unmanned testing; hyperbaric; scuba; oxygen sensor; composite gas cylinder; carbon dioxide monitoring; decompression; hyperbaric oxygen therapy; Systemteknik; Systems Engineering;

    Sammanfattning : The survival of humans in underwater environments necessitates a comprehensive understanding of both physiological factors and advanced technologies. Diving with self-contained underwater breathing apparatuses (SCUBA) remains one of the most common ways for human underwater activities. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aqueous chemical growth method; ZnO nanorods; Oxygen plasma treatment; Piezoelectric and mechanical properties; Atomic force microscope; Nanoindentation; Co3O4 nanostructures; Anions effect; pH sensor; NiCo2O4 nanostructures; Glucose sensor;

    Sammanfattning : The main objective of nanotechnology is to build self-powered nanosystems that are ultrasmall in size, exhibit super sensitivity, extraordinary multi functionality, and extremely low power consumption. As we all know that 21st century has brought two most important challenges for us. One is energy shortage and the other is global warming. LÄS MER

  7. 5. Improving the Performance of Gas Sensor Systems with Advanced Data Evaluation, Operation, and Calibration Methods

    Författare :Manuel Bastuck; Andreas Schütze; Mike Andersson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In order to facilitate the widespread use of gas sensors, some challenges must still be overcome. Many of those are related to the reliable quantification of ultra-low concentrations of specific compounds in a background of other gases. LÄS MER
