  1. 31. GC-MS based metabolomics – Development of a next generation GC-MS method and its application to nutrition and biomarker research

    Författare :Otto Savolainen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gas chromatography; nutrition; biomarkers; metabolomics; mass spectrometry; type 2 diabetes;

    Sammanfattning : Metabolomics, the measurement of a broad range of small molecules in a sample, is maturing as a field in analytical chemistry and becoming a standard research tool in biological sciences for helping to generate a wider understanding of the complex biological mechanisms behind, for example, development of disease and effects of diet on health. Metabolomics analysis is generally divided into either targeted or untargeted metabolomics. LÄS MER

  3. 32. Aspects on probabilistic approach to design : From uncertainties in pre-investigation to final design

    Författare :Anders Prästings; Stefan Larsson; Rasmus Müller; Jan Laue; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability-based design; Geotechnical design; Geotechnical structures; Sheet-pile wall; Characterization of uncertainties; Geotechnical investigations;

    Sammanfattning : Geotechnical engineering is strongly associated with large uncertainties. Exploring a medium (soil) that is almost entirely and completely hidden from us is no easy task. Investigations can be made only at discrete points, and the majority of a specific soil volume is never tested. LÄS MER

  4. 33. Drug utilization 90% : using aggregate drug statistics for the quality assessment of prescribing

    Författare :Björn Wettermark; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Drug sales statistics; drug utilization; feedback general practitioners; guidelines; indicators; intervention; prescribing; quality indicators;

    Sammanfattning : Introduction: There is room for improvement in prescribing. Although a range of indicators have been developed to assess the quality of prescribing, none of them focus on all drugs and there is a gap between what is credible for health care professionals and what can be achieved with the readily available data.

  5. 34. Factors Associated with Motorcylists' Safety at Access Points along Primary Roads in Malaysia

    Författare :Marizwan Manan; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; access point; primary road; motorcyclists’ behavior; Safety Performance function; Motorcycle accident fatality;

    Sammanfattning : More than 50% of road accident fatality victims in Malaysia are motorcyclists, numbering more than 4,000 fatalities per year. The aim of this thesis is to investigate motorcyclists’ road safety problems in general in Malaysia, and narrow down the focus to the most salient road infrastructure related risk factors. LÄS MER

  7. 35. Clinical and methodological aspects on perineal laceration diagnostics at childbirth

    Författare :Sofia Pihl; Marie Blomberg; Eva Uustal Fornell; Siw Carlfjord; Pepe Salvesen; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background: Obstetric perineal lacerations are common after vaginal birth. The degree of obstetric perineal laceration is defined by the extent of tissue involved in the laceration. When a perineal laceration has occurred after vaginal delivery, the examination for correct diagnostics is essential before primary suturing. LÄS MER
