  1. 36. Essays on Dynamic Political Economy

    Författare :Zheng Song; Fabrizio Zilibotti; Jose Rodriguez Mora; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Dynamic Political Economy; Economics; Nationalekonomi;

    Sammanfattning : This thesis consists of three papers in dynamic political economy:"Ideology and the Determination of Public Policy Over Time" investigates how public policy responds to persistent ideological shocks in dynamic politico-economic equilibrium. We develop a tractable model to analyse the dynamic interactions among ideology, public policy and individuals' intertemporal choice. LÄS MER

  3. 37. Differential maturation of Na+,K+-ATPase in the rat : transcriptional regulation by glucocorticoids

    Författare :Zheng-Ming Wang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :glucocorticoids; ontogeny; Na ; K -ATPase; H ; K -ATPase; iontransporter; kidney; lung; heart; stomach; colon.;

    Sammanfattning : Na+,K+-ATPase is a ubiquitous transmembrane enzyme that creates the electrochemical gradient across the cell membrane. Na+,K+-ATPase activity is low in many immature tissues. LÄS MER

  4. 38. Metal release from stainless steel and CoCrMo alloys in protein-rich environments – effects of protein aggregation, friction, and irradiation

    Författare :Zheng Wei; Yolanda Hedberg; Inger Odnevall Wallinder; Daniel Klint; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal release; stainless steel; CoCrMo; protein aggregation; friction; irradiation; Vroman effect; Kemi; Chemistry;

    Sammanfattning : Highly corrosion-resistant alloys are used in sensitive environments such as the human body and food environments. However, even tiny amounts of released metals from these surfaces could potentially cause adverse effects. It is hence important to study the biointerface between corrosion-resistant alloys and protein-rich environments. LÄS MER

  5. 39. Characterisation of the Clp Proteins in Arabidopsis thaliana

    Författare :Bo Zheng; Adrian K. Clarke; Vaughan Hurry; Cecilia Sundby-Emanuelsson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Arabidopsis; molecular chaperone; protein degradation; protease; Clp Hsp100; ClpP; stress response; antisense repression; chloroplast development; Växtfysiologi; Plant physiology; Växtfysiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Unlike in the greenhouse, plants need to cope with many environmental stresses under natural conditions. Among these conditions are drought, waterlogging, excessive or too little light, high or low temperatures, UV irradiation, high soil salinity, and nutrient deficiency. LÄS MER

  7. 40. Cellulose-fiber-based thermal insulation materials with fungal resistance, improved water resistance and reaction-to-fire properties

    Författare :Chao Zheng; Monica Ek; Dongfang Li; Lars Wågberg; Folke Björk; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; birch bark; cellulose; reaction-to-fire properties; fungal resistance; thermal insulation; water resistance; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Thermal insulation materials made from natural fibrous materials, such as cellulose fibers, have advantages over others from a sustainability point of view. However, cellulosic materials are generally prone to mold and absorb moisture, and these have negative effects on the insulation properties, the durability of insulation materials, and interior air quality.
