The latest long-term plan for science and technology reflects China’s determination both to overcome growing domestic social and environmental problems through technology and to become a world leader in innovation. This latest fifteen-year plan presents no radical departure from earlier strategies and continues to define policymaking by Beijing’s strong belief that innovation can be “decreed” top-

This thesis introduces a new deformation scheme for Lie algebras, which we refer to as ?quasi-deformations? to clearly distinguish it from the classical Grothendieck-Schlessinger and Gers-tenhaber deformation schemes. The main difference is that quasi-deformations are not in gene-ral category-preserving, i.e., quasi-deforming a Lie algebra gives an object in the larger catego-ry of ?quasi-Lie alge

Popular Abstract in Swedish Polymerer och tensider är molekyler som vi stöter på dagligen. Många produkter som vi använder, t.ex. tvål och tvättmedel, målarfärg eller olika läkemedel, innehåller dessa typer av molekyler. Din arvsmassa, ditt DNA, är en polymer och väggarna i dina celler är uppbyggda av s.k. lipider som är en sorts tensider. Dessa typer av molekyler har alltså väldigt stor betydelsePolyelectrolytes and oppositely charged surfactants interact through attractive electrostatic forces, which in many cases lead to phase separation already at low total concentrations. During the past 10-15 years investigations of these systems have been simplified through the use of complex salts that consist of surfactants with polymeric counterions in a 1:1 charge stoichiometry (no excess simple

This thesis is a summary of six papers which concern synthesis of optically active bicyclo[2.2.2]octane derivatives. The derivatives prepared are important building blocks in a study towards a possible replacement of the diterpenoidic part of taxol, (baccatin III), so as to construct a taxol mimic. Some of the derivatives have also been developed into new bidentate ligands. TitaniumIV complexes of

Popular Abstract in Swedish Arcanobacterium haemolyticum (A. haemolyticum) beskrevs för första gången under namnet Corynebacterim haemolyticum av MacLean och medarbetare 1946. Bakterien odlades fram från svalget hos patienter med halsont och från sår. Patienterna bestod av amerikanska soldater och infödda öbor i Stilla havet. Från olika delar av världen har senare beskrivits halsont och utslag hosIn an 18-month period all throat cultures in our laboratory were examined for Arcanobacterium haemolyticum and clinical information was obtained. The great majority of the patients suffered from pharyngitis or tonsillitis, accompanied by a rash in 46% of cases. One third of the patients had a history of recurrent tonsillitis. Three types of exanthema was described, scarlatiniform, urticarial and e
