  1. 1. When bioelectrochemical systems meet extremophiles, possibilities and challenges

    University dissertation from Kalmar, Växjö : Linnaeus University Press

    Author : Gaofeng Ni; Linnéuniversitetet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acidophiles; psychrophiles; haloalkaliphiles; bioelectrochemical systems; microbial sulfur metabolism; 16S rRNA gene amplicon sequencing; metagenomics; metatranscriptomics; Mikrobiologi; Microbiology;

    Abstract : 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. READ MORE

  2. 2. A Study on Particle Motion and Deposition Rate Application in Steel Flows

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Peiyuan Ni; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel flow; ladle teeming; continuous casting; non-metallic inclusion behavior; particle deposition; nozzle clogging; numerical simulation.;

    Abstract : 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. READ MORE

  3. 3. Numerical Study on Steel Flow and Inclusion Behavior during a Ladle Teeming Process

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Peiyuan Ni; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel flow; ladle teeming; numerical simulation; inclusion behavior; CFD; clogging; deposition.;

    Abstract : Inclusions in molten steel have received worldwide concern due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the deoxidation process, reoxidation by air and/or slag due to an entrainment during steel transfer, and so on. READ MORE

  4. 4. Multiple amyloid binding sites in Alzheimer brain and their interaction with synaptic and inflammatory mechanisms

    University dissertation from Stockholm : Karolinska Institutet, Dept of Neurobiology, Care Sciences and Society

    Author : Ruiqing Ni; Karolinska Institutet.; Karolinska Institutet.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Alzheimer’s disease (AD) is the most common type of dementia. A series of pathophyslogical changes start many years prior to the emergence of clinical symptoms. READ MORE

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

    University dissertation from Västerås : Mälardalen University

    Author : Ying Ni; Mälardalens högskola.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nonlinearly perturbed renewal equation; perturbed renewal equation; nonlinear perturbation; non-polynomial perturbation; perturbed risk process; perturbed storage process; MATHEMATICS Applied mathematics Mathematical statistics; MATEMATIK Tillämpad matematik Matematisk statistik; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Abstract : 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. READ MORE
