  1. 1. Electrical Characterization of Silicon Nanogaps

    Författare :Jonas Berg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic molecules; Molecular electronics; Surface leakage currents; Low-frequency noise; Soft breakdown; TSRAM; Resonant tunneling diodes; Selective etching; Silicon nanogaps; Nanocontacts;

    Sammanfattning : We have designed and manufactured silicon nanogaps aimed at electrically interfacing molecules, utilizing the precision thickness control in an oxidation process. An insulating layer was formed on a silicon wafer, and then polysilicon was deposited on top. LÄS MER

  3. 3. In-Plane Shear Modulus of Cross-Laminated Timber

    Författare :Jonas Sharifi; Sven Berg; Dick Sandberg; Mats Ekevad; Reinhard Brandner; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Science and Engineering;

    Sammanfattning : Cross-laminated timber (CLT) is a building component used in walls, floors, roofs, or beams in a building. The advantages of using CLT as a building component are, among others, its high load-carrying capability and the possibility of pre-fabrication. LÄS MER

  4. 4. Surviving the ratchet : Modelling deleterious mutations in asexual populations

    Författare :Jonas Söderberg; Otto Berg; Laurence Loewe; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Theoretical biology; Population genetics; Stochastic modelling; Genome evolution; Muller s Ratchet; Genetics; Genetik; Organism biology; Organismbiologi; Biology; Biologi; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : One of the most unforgiving processes in nature is that of Muller's ratchet, a seemingly irreversible accumulation of deleterious mutations that all organisms have to deal with or face extinction. The most obvious way to avoid fitness collapse is recombination, though asexual populations usually do not have the luxury of recombining freely. LÄS MER

  5. 5. Heparin-binding protein and organ failure in critical illness

    Författare :Jonas Tydén; Joakim Johansson; Magnus Hultin; Jakob Walldén; Sören Berg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heparin-binding protein; Critical care; Shock; Acute respiratory distress syndrome; Acute kidney injury; Ventilator induced lung injury; Renal clearance; Anaesthesiology; anestesiologi;

    Sammanfattning : Background: For patients severely ill enough to require care in an intensive care unit (ICU), both the disease itself (e.g. bacteria in the blood in sepsis or fractures after trauma) and effects of the immune system can cause circulatory, pulmonary, or renal dysfunction. Leukocytes play a dominant role in the immune system. LÄS MER
