  1. 11. The operating cycle representation of road transport missions

    Författare :Luigi Romano; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating cycle; transport application; road mission; probability distributions; stochastic processes; energy estimation;

    Sammanfattning : The difficulties that conventionally road vehicles are facing in meeting regulation standards require ad-hoc solutions. Moreover, the impellent shift of paradigm towards full electrification and partial automation is posing great challenges to the automotive industry, which has set a zero-emissions target to be reached within a short time horizon.

  3. 12. Cell cycle regulation in cancer: A noncoding perspective

    Författare :Mohamad Ali; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long Noncoding RNA; lncRNA; Cell cycle; S phase; Mitosis; Checkpoint; Cancer; SCAT7; LY6K-AS;

    Sammanfattning : The cell cycle progression is tightly regulated to ensure error-free cell replication. The complexity of the transcriptional machinery aids to function in a spatiotemporal pattern across different phases and genomic loci. LÄS MER

  4. 13. Life Cycle Impacts of Road Infrastructure : Assessment of energy use and greenhouse gas emissions

    Författare :Sofiia Miliutenko; Anna Björklund; Robert Karlsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cumulative Energy Demand CED ; Global Warming Potential GWP ; Life Cycle Assessment LCA ; road infrastructure; strategic planning;

    Sammanfattning : Road infrastructure is essential in the development of human society, but has both negative and positive impacts. Large amounts of money and natural resources are spent each year on its construction, operation and maintenance. Obviously, there is potentially significantenvironmental impact associated with these activities. LÄS MER

    Sammanfattning : Carbon dioxide (CO2) emissions from human activities are driving climate change, but the pending crisis could be mitigated by a circular carbon economy where released CO2 is recycled into commodity chemicals. Autotrophic microbes can make a contribution by producing chemicals, such as biofuels, from CO2 and renewable energy. LÄS MER

  7. 15. Thermodynamic Cycles using Carbon Dioxide as Working Fluid : CO2 transcritical power cycle study

    Författare :Chen Yang; Lundqvist Per; Carlos Infante Ferreria; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The interest in utilizing the energy in low‐grade heat sources and waste heat is increasing. There is an abundance of such heat sources, but their utilization today is insufficient, mainly due to the limitations of the conventional power cycles in such applications, such as low efficiency, bulky size or moisture at the expansion outlet (e.g. LÄS MER
