  3. 2. Tracing marine hypoxic conditions during warm periods using a microanalytical approach

    Författare :Sha Ni; Centrum för miljö- och klimatvetenskap (CEC); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; environmental changes; hypoxia; foraminifera; Eemian; Holocene; trace elements; stable isotopes; LA-ICP-MS; synchrotronbased μXRF;

    Sammanfattning : Deoxygenation, i.e. loss of oxygen from the oceans, often considerably influences the aquatic organisms and the wholeecosystem and changes biogeochemical cycles. It results in increasing bottom areas of hypoxia (. LÄS MER

  4. 3. When bioelectrochemical systems meet extremophiles, possibilities and challenges

    Författare :Gaofeng Ni; Mark Dopson; Bert Hamelers; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acidophiles; psychrophiles; haloalkaliphiles; bioelectrochemical systems; microbial sulfur metabolism; 16S rRNA gene amplicon sequencing; metagenomics; metatranscriptomics; Mikrobiologi; Microbiology;

    Sammanfattning : Extremophiles are microorganisms live and thrive in extreme environments that are harsh and hostile to most forms of life on earth (e.g. low pH, low temperature, high pH and high salinity). They have developed strategies to obtain nutrients and conserve energy to sustain life under these adverse conditions. LÄS MER

  5. 4. Nonlinearly Perturbed Renewal Equations : asymptotic Results and Applications

    Författare :Ying Ni; Dmitrii Silvestrov; Anatoliy Malyarenko; Mats Gyllenberg; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nonlinearly perturbed renewal equation; perturbed renewal equation; nonlinear perturbation; non-polynomial perturbation; perturbed risk process; perturbed storage process; Mathematical statistics; Matematisk statistik; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Sammanfattning : In this thesis we investigate a model of nonlinearly perturbed continuous-time renewal equation. Some characteristics of the renewal equation are assumed to have non-polynomial perturbations, more specifically they can be expanded with respect to a non-polynomial asymptotic scale. LÄS MER

  7. 5. A Study on Particle Motion and Deposition Rate : Application in Steel Flows

    Författare :Peiyuan Ni; Pär Jönsson; Lage Jonsson; Mikael Ersson; Stein Tore Johansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel flow; ladle teeming; continuous casting; non-metallic inclusion behavior; particle deposition; nozzle clogging; numerical simulation.;

    Sammanfattning : Non-metallic inclusions in molten steel have received worldwide attention due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the de-oxidation process, the re-oxidation by air and/or slag due to an entrainment during steel transfer, and so on. LÄS MER
