  1. 1. Reaction Between Grignard reagents and Heterocyclic N-oxides : Synthesis of Substituted Pyridines, Piperidines and Piperazines

    Författare :Hans Andersson; Fredrik Almqvist; Hans Adolfsson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Grignard reagents; pyridine N-oxide; pyrazine N-oxide; dienal-oxime; pyridine; ortho- metalation; piperidine; piperazine; asymmetric; Organic synthesis; Organisk syntes; organisk kemi; Organic Chemistry;

    Sammanfattning : This thesis describes the development of new synthetic methodologies for preparation of bioactive interesting compounds, e.g. substituted pyridines, piperidines or piparazines. Thesecompounds are synthesized from commercially available, cheap and easily prepared reagents, videlicet the reaction between Grignard reagents and heterocyclic N-oxides. LÄS MER

  3. 2. On the Military Utility of Spectral Design in Signature Management : a Systems Approach

    Författare :Kent Andersson; Jouko Vankka; Gunnar Hult; Hans Kariis; Hans Liwång; Harold Lawson; Jari Hartikainen; Försvarshögskolan; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; military utility; survivability; signature management; systems engineering; camouflage; Low Observable Technology; spectral design; multi-spectral; Försvarssystem; Military Technology;

    Sammanfattning : There is an ongoing duel between military sensor development and developments in signature management. The last decade, with warfare characterized by joint expeditionary operations and asymmetry, has favored sensors. LÄS MER

  4. 3. Methods and Applications in Comparative Bacterial Genomics

    Författare :Hans-Henrik Fuxelius; Siv Andersson; Björn Andersson; Uppsala universitet; []
    Nyckelord :Biology; Biologi;

    Sammanfattning : Comparative studies of bacterial genomes, now counting in the hundreds, generate massive amounts of information. In order to support a systematic and efficient approach to genomic analyses, a database driven system with graphic visualization of genomic properties was developed - GenComp. LÄS MER
