    Författare :Andrii Grytsan; T. Christian Gasser; Martin Kroon; Frans N. van de Vosse; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aorta; Aneurysm; AAA; Blood Flow; Wall Shear Stress; Growth and Remodeling; Mixture Model; Growth Kinematics; Fluid-Solid-Growth; Aorta; Aneurysm; AAA; Blodflöde; Vägg Skjuvspänning; Tillväxt och Strukturförändring; Blandning Modell; Tillväxt Kinematik; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Abdominal aortic aneurysm (AAA) is characterized by a bulge in the abdominal aorta. AAA development is mostly asymptomatic, but such a bulge may suddenly rupture, which is associated with a high mortality rate. Unfortunately, there is no medication that can prevent AAA from expanding or rupturing. LÄS MER

  3. 2. Properties of multilayered and multicomponent nitride alloys from first principles

    Författare :Fei Wang; Ferenc Tasnadi; Igor Abrikosov; Frank Mücklich; Claudia Draxl; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis is a theoretical exploration of properties of multilayered and multicomponent nitride alloys, in particular their mixing thermodynamics and elastic behaviors. Systematic investigation of properties of a large class of materials, such as the multicomponent nitride solid solutions, is in line with the modern approach of high-throughput search of novel materials.

    Sammanfattning : Climate change is one of the biggest global threats of the 21st century. Fossil fuels constitute by far the most important energy source for transportation and the different governments are starting to take action to promote the use of cleaner fuels. LÄS MER

  5. 4. Gasification of biochars: Evolution of pore structure, effects of alkalis and alkali release

    Författare :Saiman Ding; Klas Engvall; Efthymios Kantarelis; Jukka Konttinen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gasification; alkali release; kinetic modelling; char reactivity; pore structure; alkalis effects; förgasning; frigörande av alkalier; kinetisk modellering; kolreaktivitet; porstruktur; alkalieffekter; Chemical Engineering; Kemiteknik;

    Sammanfattning : Renewable energy sources are indispensable to meet the rising demand of energy usage  while  reducing  the  negative  environmental  impact  of utilising fossil  fuels. Gasification  is  an  efficient  technology  to  convert  biogenic waste  into  valuable gaseous products. LÄS MER

  7. 5. Carrot Juice Processing - Effects on Various Quality Aspects

    Författare :Charlotte Alklint; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modified atmosphere; shelf-life; accelerated storage; isothermal calorimetry; pressing; expression method; colour; dietary fibre; carotene; composition; carrot pomace; carrot juice; carrot pulp; acidification; Food and drink technology; Livsmedelsteknik;

    Sammanfattning : Carrots are a cold-weather crop well suited for cultivation in the south of Sweden. Carrots are generally rather inexpensive, with a market price below € 1 /kg (Sweden, 2003), whereas fresh carrot juice has a price of around € 5 /kg. LÄS MER
