  1. 21. Modification of Oxide Surfaces with Functional Organic Molecules, Nanoparticles, and Hetero-Oxide Layers

    Författare :Shilpi Chaudhary; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2015:Chaudhary;

    Sammanfattning : The research work described in this thesis is concerned with the modification of oxide surfaces, as reflected by its title. The surfaces and their modification have been studied using a range of experimental surface characterization tools, in particular x-ray photoelectron spectroscopy (XPS), fluorescence microscopy, scanning electron microscopy, atomic force microscopy, and scanning tunneling microscopy.

  3. 22. The influence of abdominal surgery on energy expenditure and working capacity

    Författare :Margareta Öhrström; Människan i rörelse: hälsa och rehabilitering; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; maximum oxygen uptake; chemotherapy; walking; Energy expenditure; treatment outcome;

    Sammanfattning : The overall aim of this work was to study the influence of surgery on energy expenditure (EE) during working capacity measurements and during walking. In the first study the aim was to investigate whether two different devices were sensitive enough to reveal differences in energy expenditure during treadmill walking, and if the measurements were reproducible.

  4. 23. Diagnosis of acute and chronic enteric fever using metabolomics

    Författare :Elin Näsström; Henrik Antti; Anders Johansson; Peter Spégel; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Enteric fever; Salmonella; chronic carriers; metabolomics; diagnosis; biomarkers; multivariate data analysis; GCxGC-MS; GC-MS; LC-MS;

    Sammanfattning : Enteric (or typhoid) fever is a systemic infection mainly caused by Salmonella Typhi and Salmonella Paratyphi A. The disease is common in areas with poor water quality and insufficient sanitation. Humans are the only reservoir for transmission of the disease. LÄS MER

  5. 24. Data preparation, hydrodynamic and contaminant transport shallow-water simulations of Lake Victoria

    Författare :Seema Paul; Vladimir Cvetkovic; Jesper Oppelstrup; Roger Thunvik; Felix Mtalo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake bathymetry model; Steady-state analysis; Numerical model validation; Lake water balance; Correlation and seasonal variations; Solute transport; Vattendjupskarta; Validering av numerisk modell; Vattenbalans; Korrelationer och säsongs-variation; Transport av lösliga ämnen; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : This study explores shallow lake numerical hydrodynamic processes that support model development and validation, extreme events and effects of water circulation in Lake Victoria. Lake Victoria is the second largest freshwater lake in the world, and the largest in East Africa. LÄS MER

  7. 25. Molecular methods in malaria control in the era of pre-elimination

    Författare :Ulrika Morris; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Increased funding combined with effective malaria control methods for prevention, diagnosis, and treatment, has resulted in a 30% reduction of the global malaria burden over the last decade. As malaria prevalence declines in areas of successful malaria control, the proportion of subpatent infections that fall below the detection level of malaria rapid diagnostic tests (RDTs) and microscopy increases.
