  1. 1. Control of Wear-Resistance Properties in Ti-added Hypereutectic High Chromium Cast Iron

    Författare :Qiang Liu; Pär Jönsson; Keiji Nakajima; José Tinoco; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High Chromium Cast Iron; cooling rate; Ti addition; M7C3; TiC; carbides size distributions; volume fraction; heat treatment; microstructure; mechanical properties; wear resistance;

    Sammanfattning : High chromium cast iron (HCCI) is considered as one of the most useful wear resistance materials and their usage are widely spread in industry. The wear resistance and mechanical properties of HCCI mainly depend on type, size, number, morphology of hard carbides and the matrix structure (γ or α). LÄS MER

  3. 2. Drug resistance in mycobacterium tuberculosis

    Författare :Getahun Abate; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Multidrug-resistance; tuberculosis; cefepime; moxicillin-clavulanate; ethambutol; WIT; rifampicin; isoniazid; katG;

    Sammanfattning : Drug-resistant tuberculosis is a global public health problem. This investigation was performed to find ways of improving regimens that could be used for the treatment of drug- and multidrug-resistant TB and also to find a rapid method of diagnosis of drug resistant TB, particularly MDR-TB. Among 107 isolates of M. LÄS MER

  4. 3. Towards 6 Degrees of Freedom Seakeeping Simulations Using a Fully Nonlinear Potential Flow Method

    Författare :Francesco Coslovich; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ship Motions; Added Resistance; Boundary Element Method; Fully Nonlinear Potential Flow; Seakeeping;

    Sammanfattning : In recent years, the International Maritime Organization introduced a new set of rules in order to try to reduce emissions of ships by improving their efficiency. To assess the energy efficiency of a new ship, the regulations require to estimate the Energy Efficiency Design Index (EEDI), which represent the amount of Carbon Dioxide produced per mile in relation to the amount of cargo carried, and verify that it is smaller than a prescribed value.

  5. 4. Defence and signalling in Potato-Phytophthora infestans interactions

    Författare :Ashfaq Ali; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phytophthora infestans; Plant defence; hypersensitive response; resistance; susceptibility;

    Sammanfattning : Potato is one of the major food crops and its yield is severely affected by late blight disease caused by Phytophthora infestans. P. infestans has the ability to manipulate plant defence signalling by secreting effector molecules causing so called effector triggered susceptibility. LÄS MER

  7. 5. Insulin resistance and cardiovascular function - Observational, translational and interventional studies

    Författare :Helena Utkovic Westergren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Insulin resistance; microvascular function; peripheral vascular function; coronary flow reserve; prognosis; myocardial perfusion scintigram; animal model;

    Sammanfattning : Background: Microvascular disease is now recognized as an important driver for cardiovascular mortality and morbidity. Diabetic patients are known to suffer from this condition, leading to e.g. coronary ischemia as well as kidney dysfunction. LÄS MER
