  2. 11. Energy-Related Metabolites during and after Induced Myocardial Ischemia and Retroperfusion of the Coronary Sinus : An Experimental Study in the Pig with the Microdialysis Technique and Extracorporeal Circulation

    Author : Vitas Zemgulis; Rolf Ekroth; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Ischemia; myocardial infarction; reperfusion; energy metabolism; coronary sinus retroperfusion; microdialysis; taurine; nucleoside transport; adenosine; aerobic lactate production; Kirurgi; Surgery; Kirurgi; Thoracic and Cardivascular Suregery; kirurgi; särskilt thoraxkirurgi;

    Abstract : In the clinical setting great efforts have been made with contradictory results to operate upon acutely myocardial ischemic patients. The reasons for the absence of unambiguous results are not well understood nor are they scientifically explored. READ MORE

  4. 12. The ECJ's Adjudication of Fundamental Rights Conflicts : In Search of a Fair Balance

    Author : Lars Karlander; Thomas Bull; Tuomas Ojanen; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Fundamental rights; Rights conflicts; Constitutional EU law; ECJ; CJEU; Adjudication; Proportionality; Balancing; Konstitutionell rätt; Constitutional Law;

    Abstract : This dissertation examines how the European Court of Justice (ECJ) adjudicates conflicts between fundamental rights. It has the two-fold purpose of surveying and analysing the Court’s case law to identify the methods currently being employed, and to make suggestions on how the methodology can be improved.

  5. 13. To Bee or Not to Be : Critical Floral Resources of Wild-Bees

    Author : Magnus Larsson; Anders L Nilsson; Jon Ågren; Björn Cederberg; James H Cane; Uppsala universitet; []
    Keywords : Ecology; Andrena hattorfiana; Andrena marginata; Andrenidae; Knautia arvensis; limitation; oligolecty; pollen; pollination; solitary bee; specialist bee; Succisa pratensis; Ekologi;

    Abstract : In recent decades, the development of strategies to prevent or slow the loss of biodiversity has become an important task for ecologists. In most terrestrial ecosystems wild-bees play a key role as pollinators of herbs, shrubs and trees. The scope of this thesis was to study 1) pollinator effectiveness of specialist bees vs. READ MORE

  6. 14. Annealing of Cu2ZnSn(S,Se)4 Thin Films : A Study of Secondary Compounds and Their Effects on Solar Cells

    Author : Yi Ren; Charlotte Platzer-Björkman; Maarja Grossberg; Uppsala universitet; []
    Keywords : Annealing; sputtering; thin film; CZTS; secondary phases; solar cell; Engineering Science; Teknisk fysik;

    Abstract : Kesterite Cu2ZnSnS4 (CZTS) is interesting as a sustainable photovoltaic technology due to its earth-abundant elements and suitable semiconducting properties. To date, a record efficiency of 12.6% has been achieved but further improvements are required to reach high efficiency for industrial implementation. READ MORE

  7. 15. Development of analytical methods for the determination of the small molecule component of complex biological systems

    Author : Kristian Pirttilä; Mikael Hedeland; Curt Pettersson; Torbjörn Arvidsson; Thomas Moritz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metabolomics; data processing; peak characterization; algorithm; multivariate data analysis; chromatography; sequential columns; HILIC; RPLC; liquid chromatography; mass spectrometry; LC; MS; noise-induced hearing loss; NIHL; guinea pig; perilymph; method development; validation; R; C ; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

    Abstract : The research field of untargeted metabolomics aims to determine the relative abundance of all small metabolites in a biological system in order to find biomarkers or make biological inference with regards to the internal or external stimuli. This is no trivial aim, as the small metabolites are both vast in numbers and extremely diverse in their chemical properties. READ MORE
