  1. 1. Drivers of evolutionary change in Podospora anserina

    Författare :Sandra Lorena Ament-Velásquez; Hanna Johannesson; Bengt Olle Bengtsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Podospora; Meiotic drive; Spore killing; vegetative incompatibility; heterokaryon incompatibility; allorecognition; speciation; Transposable elements; selfish genetic elements; fungi; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Genomic diversity is shaped by a myriad of forces acting in different directions. Some genes work in concert with the interests of the organism, often shaped by natural selection, while others follow their own interests. The latter genes are considered “selfish”, behaving either neutrally to the host, or causing it harm. LÄS MER

  3. 2. Reverse Engineering of Legacy Real-Time Systems : An Automated Approach Based on Execution-Time Recording

    Författare :Joel Huselius; Hans Hansson; Henrik Thane; Antonia Bertolino; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap; Datavetenskap;

    Sammanfattning : Many real-time systems have significant value in terms of legacy, since large efforts have been spent over many years to ensure their proper functionality. Examples can be found in, e.g., telecom and automation-industries. LÄS MER

  4. 3. A Tomographic Measurement Technique for Irradiated Nuclear Fuel Assemblies

    Författare :Staffan Jacobsson Svärd; Anders Bäcklin; Ane Håkansson; Klaas van der Meer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; tomography; nuclear fuel; SPECT; core physics; validation; pin power; safeguards; partial-defect verification; Kärnfysik; Nuclear physics; Kärnfysik;

    Sammanfattning : The fuel assemblies used at the Swedish nuclear power plants contain typically between 100 and 300 fuel rods. An experimental technique has been demanded for determining the relative activities of specific isotopes in individual fuel rods without dismantling the assemblies. LÄS MER

  5. 4. Situation-aware vehicles : supporting the next generation of cooperative traffic systems

    Författare :Kristoffer Lidström; Tony Larsson; Steven E. Shladover; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datavetenskap;

    Sammanfattning : Wireless communication between road vehicles enables a range of cooperative traffic applications including safety, efficiency and comfort functions. A common characteristic of the envisioned applications is that they act on environmental information to intepret traffic situations in order to provide the driver with warnings or recommendations.

  7. 5. Molecular-level Simulations of Cellulose Dissolution by Steam and SC-CO2 Explosion

    Författare :Faranak Bazooyar; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; molecular modelling; cellulose; steam explosion; SC-CO2 explosion; Resource Recovery; Resource Recovery; Resursåtervinning;

    Sammanfattning : Dissolution of cellulose is an important but complicated step in biofuel production from lignocellulosic materials. Steam and supercritical carbon dioxide (SC-CO2) explosion are two effective methods for dissolution of some lignocellulosic materials. Loading and explosion are the major processes of these methods.
