  1. 1. Learning control for flex-fuel CI engine and fuel cell

    Författare :Xiufei Li; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flex-fuel CI Engine; Fuel Cell; Model Predictive Control; Learning Control; Adaptive Control; Gas System Model; Ignition Delay Model; Data-based Modeling; Gaussian process;

    Sammanfattning : This thesis investigated the modeling and control problems in the context of the flex-fuel compression-ignition (CI) engine and fuel cell, which shows great potential in the transition from fossil fuel to renewable energy sources.The modeling parts included the flex-fuel engine combustion process and intake system, and the system scale fuel cell model.

  3. 2. Mechanisms and regulations of priming effects in soil

    Författare :Jian Li; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Soil organic matter (SOM) plays a significant role in the global carbon (C) and nutrients cycles, not only since SOM is a major storage reservoir of C and plant nutrients, but also since microbial decomposition of SOM releases large quantities of CO2 to the atmosphere. The accelerated or reduced turnover rate of SOM after the input of labile C compounds is a phenomenon known as the priming effect (PE). LÄS MER

  4. 3. Quality of muscle foods : effects of feed and storage time

    Författare :Shengjie Li; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The overall aim of this thesis was to investigate the effects of feed and storage time on meat quality. To study the effect of feed, chicken were fed seven steam-pelleted or nonpelleted rapeseed (RS) diets with different RS inclusion levels (0, 80, 160, and 240 g/kg) for 34 days, and the dietary effects on meat yield, fatty acid composition in meat, and the expression of lipid metabolism-related genes in liver were determined.

  5. 4. Na,K-ATPase as signaling transducer

    Författare :Juan Li; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : It is now generally agreed that Na,K-ATPase (NKA), in addition to its role in the maintenance of Na+ and K+ gradients across the cell membrane, is a signal transducer. Our group has identified a novel signaling pathway where NKA interact with IP3R to form a signaling microdomain. LÄS MER

  7. 5. Processing, stability and interactions of lung surfactant protein C

    Författare :Jing Li; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Mature SP-C is a 4.2 kDa transmembrane protein which is uniquely expressed in the alveolar type II cell. Human SP-C is generated via multistep proteolytic cleavage of both the C-terminal and Nterminal regions of proSP-C. LÄS MER
