1. 31. Multiscale Constitutive Modeling of Heterogeneous Engineering Materials

   Författare :Johan Jansson; Kent Salomonsson; Jakob Olofsson; Julian J. Rimoli; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This work deals with different methods used to determine heterogeneous constitutive model parameters for macro-scale finite element models, based on microstructural variations, caused by the manufacturing process. These methods could be applied to decrease modeling errors associated with the material behavior, improving the predictive capabilities of structural analyses in simulation-driven industrial product development.

3. 32. Cement-Poor Concrete and Grout for Use in Underground Constructions

   Författare :Mohammed Hatem; Leena Korkiala-Tanttu; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : This thesis deals with the composition and properties of cement-based materials, concrete and grout, for use as seals and for stabilizing fracture zones in underground facilities like mines and repositories for chemical and radioactive waste. It is of general character with respect to the composition and preparation of concretes and grouts but focuses on the sealing of boreholes for mineral prospection and site investigation for locating underground repositories of hazardous waste.

4. 33. Bio-based barriers from wood hydrolysates : A pilot-scale approach

   Författare :Soheil Saadatmand; Ulrica Edlund; Youssef Habibi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood hydrolysate; biorefinery; oxygen permeability; multilayer barriers; food packaging.; vedhydrolysat; syrgaspermeabilitet; barriärskikt; livsmedelsförpackning;

   Sammanfattning : Wood hydrolysates (WHs) are liquids extracted from the hydrothermal treatment of wood. They exist as the byproduct of forestry industries such as the dissolving pulp and fiberboard industries. WHs are hemicellulose-based with a large share of lignin in the chemical composition.

5. 34. The effects of valenced odors on facial perception

   Författare :Elmeri Syrjänen; Jonas Olofsson; Håkan Fischer; Thomas Hummel; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Valenced odors; Facial expressions; Disgust; Happiness; Olfaction; Emotion; Reaction Times; Evaluation; Ratings; EEG; ERP; N170; Psychology; psykologi;

   Sammanfattning : We use our senses to navigate in the world. An important property of olfaction, the sense of smell, is to enable us to approach beneficial things, and to avoid what might be toxic or otherwise harmful in our environment. Other peoples’ behaviors are also paramount for our survival. LÄS MER

7. 35. Synthesis and Characterization of MgA1ON-BN refractories

   Författare :Zuotai Zhang; Seshadri Seetharaman; Kazuhiro Nagata; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MgAlON-BN composites; Mechanical properties; Thermal shock durability; Thermal diffusivity conductivity; Corrosion resistance.; Metallurgical process engineering; Metallurgisk processteknik;

   Sammanfattning : In order to meet the need of metallurgical industry in the world, a new MgAlON-BN composite which can be used for example in special refractory nozzles, tubes and break rings for the continuous casting of steel was studied in the present thesis. The aim was to understand the mechanism of synthesis and their physicochemical properties during the application. LÄS MER
