  3. 2. Female Employment and Fertility Change in South Korea

    Författare :Li Ma; Gunnar Andersson; Gerda Neyer; James Raymo; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Female employment; fertility change; South Korea; sociologisk demografi; Sociological Demography; Sociologi;

    Sammanfattning : A large amount of literature has addressed the relationship between women’s employment and fertility in the Western context. We have less relevant knowledge about the context of East Asia. This thesis addresses this situation by providing insight into how women’s employment is interrelated with their fertility in South Korea. LÄS MER

  4. 3. Studies of the Chinese Rectangular Array Algorithm in Nine Chapters

    Författare :Li Ma; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The rectangular array algorithm is a matrix approach for solving simultaneous linear equations. A systematic treatment of this algorithm is found in the classic "Mathematics in Nine Chapters". LÄS MER

  5. 4. CO2 electrochemical reduction: Techno-economic evaluation and experimental research for producing methanol

    Författare :Fangfang Li; Xiaoyan Ji; Joakim Lundgren; Klas Engvall; Hailong Li; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : Recently, CO2 electrochemical reduction (CO2R) has gained popularity, to cope with the strict environmental rules on greenhouse gas emissions, and to convert CO2 to value-added chemicals/fuels. Ionic liquids (ILs) have been considered as potential media for CO2R owing to their multi-functions in enhancing CO2R solubility and improving CO2R reaction rate and product selectivity. LÄS MER

  7. 5. Theoretical and Experimental Investigations of Nonlinear Flame Instability

    Författare :Li-Zheng Ma; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nonlinear hydrodynamic instability; flame propagation and stretch effects; shock induced flame instability; tulip flame formation; interface tracking; the Schlieren technique; level set approach;

    Sammanfattning : Flame instability is both important and difficult to understand. Mechanisms of instability are complex, because instability often involves an interaction between several different physical phenomena, such as an unsteady chemical reaction, unsteady flame propagation generating an unsteady flow, acoustic waves or shock waves.
