  4. 3. Biodegradable Surfactants Containing Hydrolyzable Bonds

    Författare :Maria Stjerndahl; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amide; alkaline hydrolysis; cleavable surfactant; carbonate; ester; biodegradation; CMC; enzymatic hydrolysis; mixed micelle;

    Sammanfattning : Surfactants with built-in weak bonds, so-called cleavable surfactants, are interesting candidates in the search for more environmentally friendly alternatives to traditional surfactants. The objective of this thesis was to perform a systematic study in which cleavable surfactants with different hydrolyzable bonds were compared with regard to physicochemical properties, and chemical and biological stability.

  7. 5. Det klyvbara ämnet : Diskursiva ordningar i svensk kärnkraftspolitik 1972­-1980

    Författare :Per Lindquist; Sociologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; systems theory; social movements; risk; power; nuclear power; knowledge production; environmental policy; energy policy; discourse; communicative action; autopoiesis; communication; Sociology; Sociologi;

    Sammanfattning : This study applies a qualitative discourse theoretical method to analyse the central argumentation in the parliamentary debate on nuclear power in Sweden during 1972­1980, reconstructed from official documents such as governmental and parliamentary bills, committee reports, parliamentary debate protocols, and official commission reports. Particular concern is directed to the process in which various discursive orders emerging within the political debate tend to have a structuring influence on the political argumentation regarding what can be said, by whom this can be said, and how this can be said.
