    Sammanfattning : Over the past decades, concerns for the environment have increased and efforts to achieve a sustainable society have intensified. One particular challenge is to replace fossil-based plastics with biodegradable materials produced from renewable resources. LÄS MER

  3. 22. Robust Low-Power Wide Area Networks for Sports and Health

    Författare :Charalampos Orfanidis; Martin Jacobsson; Dimitrios Zorbas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology and Health; Teknik och hälsa;

    Sammanfattning : Low-Power Wide Area Networks (LPWANs) has enriched the IoT ecosystem with new features and application scenarios. LPWANs offer long range communication and can be used to connect devices that are divided by long distances and offer connectivity to remote areas where cellular networks are not accessible. LÄS MER

  4. 23. Recovery of organic carbon from municipal waste streams

    Författare :Isaac Owusu-Agyeman; Elzbieta Plaza; Zeynep Cetecioglu; Irini Angelidaki; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; Volatile fatty acid; Anaerobic granules; Co-digestion; Municipal waste; Chemical Engineering; Kemiteknik;

    Sammanfattning : The focus of the current study was on the recovery of carbon from municipal bio-waste streams. Firstly, the relationship between methanogenic pathways and the properties of anaerobic granules was studied using two pilot-scale upflow anaerobic sludge blanket (UASB) reactors with different granule size distribution.

  5. 24. Towards understanding of complex disease etiology using sequence Capture Hi-C (HiCap) and associated high throughput functional assays

    Författare :Sailendra Pradhananga; Pelin Sahlén; Joakim Lundeberg; Benedicte Alexandra Lie; KTH; []
    Nyckelord :Capture Hi-C; RNA sequencing; Whole genome sequencing; ChIP sequencing; Chromatin loops; enhancers; promoters; Bioteknologi; Biotechnology;

    Sammanfattning : A human genome laid out in a straight line would measure 2m from end to end, but in living cells it is folded into a compact structure contained in a nuclear space with a diameter of 2µm. This compact genome is hierarchically organized and spatiotemporally regulates distinct cellular gene expression mechanisms via promoter - enhancer chromatin loops. LÄS MER

  7. 25. Structural and biochemical insights into biosynthesis and degradation of N-glycans

    Författare :Tom Reichenbach; Christina Divne; David Drew; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; N-glycan; biosynthesis; degradation; glycosyltransferase; glycoside hydrolase; biofuel; enzyme; membrane protein; Bioteknologi; Biotechnology;

    Sammanfattning : Carbohydrates are a primary energy source for all living organisms, but importantly, they also participate in a number of life-sustaining biological processes, e.g. cell signaling and cell-wall synthesis. The first part of the thesis examines glycosyltransferases that play a crucial role in the biosynthesis of N-glycans. LÄS MER
