  2. 21. ST-elevation myocardial infarction : studies of outcome in relation to fibrinolysis and ischemia monitoring with on-line vectorcardiography

    Author : Johan Nilsson; Ulf Näslund; Kurt Boman; Kristian Thygesen; Umeå universitet; []
    Keywords : Medicine; Myocardial infarction; vectorcardiography; fibrinolysis; reperfusion; Medicin; kardiologi; Cardiology;

    Abstract : The treatment of acute myocardial infarction (AMI) has undergone a tremendous development during the last decades, and the most important factor is probably the introduction of reperfusion therapy aimed at preventing or limiting the myocardial injury. It is of vital importance that patients with AMI are adequately monitored regarding the development of ECG changes during and after treatment to identify successful or failed reperfusion and to detect episodes of recurrent ischemia.

  4. 22. Studies on Oxidative Couplings in H-Phosphonate Chemistry

    Author : Johan Nilsson; Jacek Stawinski; Esther Kuyl-Yeheskiely; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; oxidative coupling; H-phosphonate; H-phosphonothioate; organisk kemi; Organic chemistry; Organisk kemi;

    Abstract : In this thesis oxidative coupling of H-phosphonate and H phosphonothioate diesters with different alcohols and amines are presented. Since the reactions with alcohols previously have been particularly unfavourable due to competing side reactions, a modified protocol leading to high coupling yields of structurally diverse hydroxylic components was developed.

  5. 23. Spatial organization of retail activities

    Author : Helena Nilsson; Johan Klaesson; Sven-Olov Daunfeldt; Özge Öner; Daniel Arribas-Bel; Jönköping University; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : This thesis is a compilation of four independent papers that examine the spatial process of retail location. The central question I ask is how changes in access to consumer demand affects retail in terms of size and survival. READ MORE

  6. 24. ADHD and stress : Diurnal cortisol levels, early psychosocial adversity and perceived stress

    Author : Johan Isaksson; Frank Lindblad; Kent W Nilsson; Per Gustafsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ADHD; HPA-axis; cortisol; hypocortisolism; diurnal rhythm; trauma; adversity; medication; perceived stress; gender differences; Child and Youth Psychiatry; Barn- och ungdomspsykiatri;

    Abstract : The Hypothalamus-Pituitary-Adrenal axis (HPA-axis) with its end product cortisol mediates the physiological response to stress thereby promoting mobilization of energy. The cortisol levels follow a diurnal rhythm with a distinct awakening response. READ MORE

  7. 25. Fibre-Optic Displacement and Temperature Sensing Using Coupling Based Intensity Modulation and Polarisation Modulation Techniques

    Author : Johan Jason; Hans-Erik Nilsson; Bertil Arvidsson; Werner Daum; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical fibre sensor; displacement measurement; temperature measurement; fibre coupling; intensity modulation; birefringence; polarisation; OTDR; side-hole fibre;

    Abstract : Optical fibre sensors are employed in the measurements of a number of different physical properties or for event detection in safety and security systems. In those environments which suffer from electromagnetic disturbance, in harsh environments where electronics cannot survive and in applications in favour of distributed detection, fibre-optic sensors have found natural areas of use.
