  2. 1. Of Mice and MYC : Modelling Medulloblastoma

    Author : Oliver Mainwaring; Fredrik J. Swartling; Charles Eberhart; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medulloblastoma; MYC; Group 3; Cdkn2a; ARF; HSP90; Chromosome 17q; Medicinsk vetenskap; Medical Science; Oncology; Onkologi;

    Abstract : Brain tumours are the leading cause of cancer-related paediatric deaths, with medulloblastoma (MB) being the most common malignant paediatric brain tumour. MB is stratified into four major subgroups – WNT, SHH, Group 3, and Group 4, nomenclature defined by key pathways and drivers involved within each subgroup. READ MORE

  4. 2. Defects and Surfaces and their Impact on Fatigue Behaviour of Powder Bed Fused Ti-6Al-4V : Characteristics and Modelling

    Author : Viktor Sandell; Marta-Lena Antti; Pia Åkerfeldt; Thomas Hansson; Stefano Beretta; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Defects; Additive Manufacturing; Ti-6Al-4V; Probabilistic Modelling; Fatigue; Extreme Value Statistics; Materialteknik; Engineering Materials;

    Abstract : Additive manufacturing (AM), of metals is gaining popularity as an alternative to conventional manufacturing techniques such as casting and forging. Metal-AM allows for the production of complex part geometries with reduced material waste and shorter lead times. READ MORE

  5. 3. Design of Thermal Barrier Coatings : A modelling approach

    Author : Mohit Kumar Gupta; Per Nylén; Nicolaie Markocsan; Christer Persson; Lech Pawlowski; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal barrier coatings; Microstructure; Thermal conductivity; Young’s modulus; Interface roughness; Thermally grown oxide; Lifetime; Finite element modelling; Design; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Atmospheric plasma sprayed (APS) thermal barrier coatings (TBCs) are commonly used for thermal protection of components in modern gas turbine application such as power generation, marine and aero engines. TBC is a duplex material system consisting of an insulating ceramic topcoat layer and an intermetallic bondcoat layer. READ MORE

  6. 4. DEM Modelling of Vibratory Screens

    Author : Ali Davoodi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Validation; Modelling; Screen efficiency; DEM simulation;

    Abstract : In Sweden, about 100 million tons of aggregate is used for road, railway, and concrete every year. Crushing is the main process for producing aggregate material in different fractions. The production process is divided into two sub-processes: comminution or size reduction and classification. READ MORE

  7. 5. Searching for the optimal radiotherapy treatment time, dose and fractionation - the role of hypoxia and reoxygenation : A modelling study

    Author : Emely Lindblom; Iuliana Toma-Dasu; Ingmar Lax; Ludvig Paul Muren; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hypoxia; Reoxygenation; SBRT; Fractionation; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : The search for the optimal choice of treatment time, dose and fractionation regimen is one of the major challenges in radiation therapy. Several aspects of the radiation response of tumours and normal tissues give different indications of how the parameters defining a fractionation schedule should be altered relative to each other which often results in contradictory conclusions.
