  2. 1. SiC-FET Gas Sensors Developed for Control of the Flue Gas Desulfurization System in Power Plants Experimental and Modeling : Experimental and Modeling

    Author : Zhafira Darmastuti; Anita Lloyd Spetz; Lars Ojamäe; Niclas Lindqvist; Mike Andersson; Bilge Saruhan-Brings; Linköpings universitet; []
    Keywords : SiC-FET sensors; temperature cycle operation; detection mechanism studies; SO2; H2S;

    Abstract : Electricity and power generation is an essential part of our life. However, powergeneration activities also create by-products (such as sulphur oxides, nitrogen oxides,carbon monoxide, etc), which can be dangerous when released to the atmosphere. READ MORE

  4. 2. H2S and dense gas in luminous infrared galaxies and their outflows

    Author : Mamiko Sato; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Keywords: Galaxies:ISM - ISM: molecules - ISM: outflows.;

    Abstract : Luminous infrared galaxies (LIRGs) are dusty galaxies that are going through an important and likely transient phase in their evolution. They experience rapid growth through bursts of star formation or an accreting supermassive black hole, an Active Galactic Nucleus (AGN). READ MORE

  5. 3. Importance of bacterial hydrogen sulfide in the pathogenesis of periodontal diseases

    Author : Amina Basic; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hydrogen sulfide; Periodontitis; Gingivitis; IL-1β; IL-18; NLRP3 inflammasome; Oral microbiota; Fusobacterium spp.; Bismuth test; L-cysteine;

    Abstract : Hydrogen sulfide (H2S) is one of many end-products of the proteolytic activities in the subgingival microbiota in patients with periodontal diseases, such as gingivitis and periodontitis. Although H2S is generally regarded as toxic, the mechanisms that underlie its production and its effects on human cells and tissues are poorly understood. READ MORE

  6. 4. A molecular exploration of sensory responses in c. elegans

    Author : Longjun Pu; Changchun Chen; Simon Tuck; Sara I Wilson; Zhiyong Shao; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; C. elegans; sensation; CRISPR Cas9; G protein-coupled receptors; neuropeptides; acute hypoxia; pathogen; chemosensation; hydrogen sulfide; HIF-1; iron;

    Abstract : Sensation provides a pivotal ability, allowing animals to survive in complex environments. The cues sensed by animals are represented by external stimuli and internal signals. However, the mechanisms mediating sensations in molecular and cellular level are still not well-studied. In this thesis, by using free-living nematodes C. READ MORE

  7. 5. Zeolite membranes for effective production of biofuels

    Author : Erik Sjöberg; Farid Akhtar; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Abstract : To deal with the increasing demand of renewable fuels, more efficient processes for the production of biofuels are needed. Zeolite membranes have the potential to improve many existing processes that could be used for production of biofuels. Methanol is a potential biofuel that may be produced from synthesis gas in an equilibrium limited reaction. READ MORE
