  2. 2. Conifer Evolution, from Demography and Local Adaptation to Evolutionary Rates : Examples from the Picea genus

    Författare :Jun Chen; Martin Lascoux; Ulf Lagercrantz; Matt Olson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Speciation; Demographics; clinal variation; convergent evolution; transcriptome; small regulatory RNA; Biologi med inriktning mot evolutionär funktionsgenomik; Biology with specialization in Evolutionary Functional Genomics; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Evolutionary process can be inferred at three different levels: the species level, the population level and the molecular level. In this thesis, I applied approaches at these three levels and aimed to get a comprehensive picture of conifer evolution, from speciation and demography to geographic variation and local adaptation, and then to the molecular evolution of proteins and small regulatory RNAs.

  3. 3. Optimizing Ice-Resistant Surfaces: Unifying Self-Healing, Durability, and Functional Design for Superior Anti-/de-icing Performance

    Författare :Jun Chen; Yijun Shi; Pär Marklund; Marcus Björling; Jianying He; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anti- de-icing; Machine Elements; Maskinelement;

    Sammanfattning : Snow and ice accumulation on critical infrastructure such as wind power turbines and power lines cause significant challenges and safety hazards in cold climate regions during wintertime. Research into anti-/de-icing technologies has been divided into two main streams, i.e., active, and passive approaches. LÄS MER

  4. 4. Selenium Compounds and Antioxidant Capacity in Bovine Milk. Studies on Glutathione Peroxidase, Bioavailability and Electrochemical Techniques

    Författare :Jun Chen; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; General biomedical sciences; Biomedicinska vetenskaper allmänt ; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; amperometry; voltammetry; antioxidant capacity; ileostomy; bioavailability; glutathione peroxidase; bovine milk; selenium;

    Sammanfattning : The efficacy and function of antioxidants have been intensively studied in foods and other biological systems in recent decades. This thesis concerns different aspects of the antioxidant properties of bovine milk, with emphasis on measurement of the total antioxidant capacity (TAC), the activity of the selenium-containing glutathione peroxidase (GSHPx), and the bioavailability of selenium from bovine milk in humans.

  5. 5. Ultra-low latency communication for 5G transport networks

    Författare :Jun Li; Jiajia Chen; Chan Vincent; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : The fifth generation (5G) mobile communication system is envisioned to serve various mission-critical Internet of Thing (IoT) applications such as industrial automation, cloud robotics and safety-critical vehicular communications. The requirement of the end-to-end latency for these services is typically within the range between 0. LÄS MER
