  1. 1. Perspektiv på Patron : Bruksägaren och statsministern Christian Lundeberg (1842–1911)

    Författare :Bo G Hall; Torkel Jansson; Christer Ericsson; Torbjörn Nilsson; Uppsala universitet; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Sweden 1870-1911; biography as scientific method; iron and steel industry; paternalistic concepts; Sweden-Norway union relations; homosocial factors; defense matters; universal suffrage; History subjects; Historieämnen; Historia; History;

    Sammanfattning : The dissertation is a biography of the industrialist and statesman Christian Lundeberg, a leading and stongly pronounced conservative actor in Swedish political life during the decades around1900, but nowadays almost forgotten. The purpose is to identify the main forces – convictions as well as external factors – behind his actions. LÄS MER

  2. 2. Active and Passive Unequally Spaced Reflect-Arrays and Elements of RF Integration Techniques

    Författare :Dhanesh G. Kurup; Anders Rydberg; Mohamed Himdi; Peter S Hall; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Electrical engineering; Active Antenna; Reflect-arrays; NRD guide; RF integration; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : Using an array synthesis tool based on a modified differential evolution algorithm, it is shown that the position-phase synthesis exhibits improved pattern characteristics compared to both the phase only and position only synthesis of uniform amplitude antenna arrays. The design of an unequally spaced planar reflect-array and an active power combining reflect-array are presented. LÄS MER

  3. 3. Transition metal-catalyzed allylic and vinylic functionalization : Method development and mechanistic investigations

    Författare :Johanna M. Larsson; Kálmán J. Szabó; Dennis G. Hall; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; palladium; copper; catalysis; Heck reaction; C-H functionalization; allylic substitution; silylation; borylation; trifluoromethylation; fluorination; mechanistic study; transition metal; alkene; allylic silane; allylic boronate; allylic fluoride; Organic Chemistry; organisk kemi;

    Sammanfattning : The use of small molecule building blocks in, for example, pharmaceutical research and new material development, creates a need for new and improved organic synthesis methods. The use of transition metals as mediators and catalysts opens up new reaction pathways that have made the synthesis of completely new compounds possible as well as greatly improved the synthetic routes to known compounds.

  4. 4. Bacteremia after oral surgical procedures and antibiotic prophylaxis

    Författare :Gunnar Hall; Karolinska Institutet; Karolinska Institutet; []

    Sammanfattning : The use of antibiotic prophylaxis in patients predisposed to infective endocarditis who are undergoing oral surgical procedures is widely accepted. Because no controlled clinical trials of antibiotic regimens for the prevention of endocarditis in humans have been done, recommendations are based on results of, e.g. LÄS MER

  5. 5. Studier i Härnösands bebyggelsehistoria : 1585-1800-talets mitt. D. 1, Samhällshistorisk bakgrund, planutveckling och offentlig bebyggelse
