  1. 21. Monitoring gene level biodiversity - aspects and considerations in the context of conservation

    Författare :Johan Charlier; Linda Laikre; Nils Ryman; Kjetil Hindar; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; brown trout; conservation genetics; genetic drift; genetic monitoring; effective population size; moose; one-sample approach; spatial genetic structure; statistical power; temporal data; populationsgenetik; Population Genetics;

    Sammanfattning : The objectives of this thesis relate to questions needed to be addressed in the context of genetic monitoring for implementing the Convention on Biological Diversity for the gene level. Genetic monitoring is quantifying temporal changes in population genetic metrics. LÄS MER

  3. 22. Microfluidic blood sample preparation for rapid sepsis diagnostics

    Författare :Jonas Hansson; Hjalmar Brismar; Aman Russom; Fredrik Nikolajeff; KTH; []
    Nyckelord :3D fluidic networks; bacteria isolation; inertial microfluidics; lab-on-chip; microfluidics; particle filtration; PDMS membrane; selective cell lysis. sepsis;

    Sammanfattning : Sepsis, commonly referred to as blood poisoning, is a serious medical condition characterized by a whole-body inflammatory state caused by microbial infection. Rapid treatment is crucial, however, traditional culture-based diagnostics usually takes 2-5 days. LÄS MER

  4. 23. Classification of High Dimensional Signals with Small Training Sample Size with Applications towards Microwave Based Detection Systems

    Författare :Yinan Yu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Classification techniques attempt to resolve the problem of categorizing data into two or more classes. The data distribution is therefore the most critical fact to be aware of. LÄS MER

  5. 24. Proton Conducting Ceramics; Synthesis, Characterization and Sample Cell Environments

    Författare :FRANCIS GACHAO KINYANJUI; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perovskites; neutron diffraction; Rietveld refinements; BaSnO3; in-situ cell; deuteron position; proton conduction; BaZrO3;

    Sammanfattning : Acceptor doped Perovskite ceramics have been shown to exhibit high levels of protonic conduction in humid atmospheres. However significant grain boundary resistance and long sintering times required to achieve sufficient grain size growth has hindered their widespread application as electrolyzers, fuel cells and gas separation membranes.
