  2. 1. Modeling and experimental characterization of large biaxial strains and induced anisotropy in pearlitic rail steel

    Author : Knut Andreas Meyer; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pearlitic steel; yield criteria; distortional hardening; axial-torsion; kinematic hardening; biaxial loading; hyperelasto-plasticity;

    Abstract : Large shear strains accumulate in the near-surface region under the running band of railway rails. In this region, rolling contact fatigue cracks often initiate, causing major problems for the railway industry. READ MORE

  4. 2. Silicone Rubber Insulators: Impacts of Material Formulation in Coastal Environment

    Author : Tomas G Gustavsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface characterization; aging; filler level; outdoor insulation; leakage current measurements; material formulation; silicone rubber; polymeric insulators; coastal environment; polydimethylsiloxane PDMS ;

    Abstract : This thesis deals with influences of material formulation on the performance of silicone rubber high voltage insulators in a coastal environment. Samples and insulators with known differences in material compositions have been used in this task. In the first step, a screening test with cylindrical samples was initiated. READ MORE

  5. 3. Development and Tailoring of Low‐Density Cellulose‐Based Structures for Water Treatment

    Author : Zhaleh Atoufi Najafabadi; Lars Wågberg; Per A. Larsson; Julien Bras; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adsorption; Aerogels; Amyloid nanofibrils; Cellulose; Cellulose nanofibrils; β- lactoglobulin; water treatment; Adsorption; Aerogel; Amyloid nanofibriller; Cellulosa; Cellulosa nanofibriller; β- laktoglobulin; vattenbehandling; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The challenges posed by our limited clean water sources and the well-known global water pollution demand more efficient water purification technologies. Additionally, the increasing environmental awareness has inspired a shift towards eco-friendly and renewable materials and technologies. READ MORE

  6. 4. Methods for Preclinical Evaluation of Cytotoxic Drugs : With Special Reference to the Cyanoguanidine CHS 828 and Hollow Fiber Method

    Author : Saadia Bashir Hassan; Elin Lindhagen; Rolf Larsson; Mats O Karlsson; Mustapha Hassan; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; CHS 828; in vitro; in vivo; hollow fiber; models; NF-kB; Farmakologi; Pharmacological research; Farmakologisk forskning;

    Abstract : The novel cyanoguanidine CHS 828 has shown promising antitumor activity in many in vitro and in vivo studies. The long-term 14 days in vitro hollow fiber cultures, where tumor cells from different tumor cell lines were cultured inside semipermeable fibers, were more resistant to CHS 828 and other cytotoxic drugs than the shorter-term 3 days cultures.

  7. 5. Non-linear model applied on composites exhibiting inelastic behavior: development and validation

    Author : Liva Pupure; Maciej Wysocki; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : The polymeric composite materials are in high demand by industries where light and strong materials are required. Although manmade fiber (e.g. glass, carbon, aramid fibers) are most often used to reinforce polymers, natural fibers due to their environmental friendliness and sustainability have been also considered.
