  1. 1. Exploring the Propanediol Utilization Pathway in Lactobacillus reuteri

    Författare :Lu Chen; Bioteknik; []
    Nyckelord :Lactobacillus reuteri; propanediol utilization pathway; microcompartment; shell proteins; glycerol; 3-hydroxypropionaldehyde; 3-hydroxypropionic acid; 1; 3-propanediol; glycerol dehydratase; 1; 3-propanediol oxidoreductase; propionaldehyde dehydrogenase; redox balance; substrate selectivity;

    Sammanfattning : Concerns regarding environmental issues have led to increasing efforts for investigating sustainable production routes for the future industry that is based on renewable resources. Among the biobased chemicals, the C3-chemicals 3-hydroxypropionaldehyde (3-HPA), 1,3-propanediol (1,3-PDO) and 3-hydroxypropionic acid (3-HP), have been identified as top candidates for the chemical industry.

    Författare :Jingjing Chen; Xiaoyan Ji; Bona Lu; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat-transfer enhancement; slurry; rheological properties; computational fluid dynamics; twisted tubes; biogas production; Energiteknik; Energy Engineering;

    Sammanfattning :  Biomethane production from renewable residues with anaerobic digestion gains increasing attention as a crucial alternative to petroleum fuels. It has been vigorously developed, but the large amounts of subsidy from the government indicate that the process efficiency needs to be further improved. LÄS MER

  4. 3. CO2 separation using ionic liquid-based absorbents : thermodynamics and kinetics

    Författare :Yifeng Chen; Xiaoyan Ji; Xiaohua Lu; Marcus Öhman; Congmin Wang; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ionic liquids; carbon dioxide; thermodynamics; kinetics; Energiteknik; Energy Engineering;

    Sammanfattning : Ionic liquids (ILs) have shown great potential to be used as absorbents for CO2 separation owing to their unique properties such as immeasurably low vapour pressure, high thermal stability, high CO2 affinity, and tunable structure. A huge amount of researches have been carried out, and most of them focused on developing novel ILs for CO2 separation. LÄS MER

  5. 4. Integrative Modeling of Epigenetic Regulation in Human Disease

    Författare :Xi Lu; Xingqi Chen; Chandrasekhar Kanduri; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioblastoma; Cross-species; Glioblastoma stem cell; Dravet syndrome; ATAC-seq; Single-cell multi-omics technology;

    Sammanfattning : Glioblastoma is the most common and aggressive primary brain tumor. Standard of treatment prove ineffective, leading to tumor recurrence and an average survival rate of 14 months. This treatment resistance is attributed to both inter-tumor and intra-tumor heterogeneity observed across diverse tumor samples and within individual cells. LÄS MER

  7. 5. Efficient Memory Access and Synchronization in NoC-based Many-core Processors

    Författare :Xiaowen Chen; Zhonghai Lu; Umit Ogras; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Many-core; Network-on-Chip; Distributed Shared Memory; Microcode; Virtual-to-physical Address Translation; Memory Access Fairness; Barrier Synchronization; Cooperative Communication; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : In NoC-based many-core processors, memory subsystem and synchronization mechanism are always the two important design aspects, since mining parallelism and pursuing higher performance require not only optimized memory management but also efficient synchronization mechanism. Therefore, we are motivated to research on efficient memory access and synchronization in three topics, namely, efficient on-chip memory organization, fair shared memory access, and efficient many-core synchronization.
