  2. 1. Impact of Surface Structures onDeposition and Erosion in a Tokamak

    Author : Yushan Zhou; Henric Bergsåker; Ivancica Bogdanovic Radovic; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Deposition; erosion; JET; micro ion beam analysis; Deposition; erosion; JET; mikrojonstråleanalys; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Fusion is a potentially unlimited and environmentally friendly energy source for human society in the future. However, along the way towards the application of fusion energy there are still unresolved complications. Among them, deposition and erosion are two critical issues. READ MORE

  4. 2. Single Fibre Collection Efficiency : Infångningseffektiviteten för ett fiber

    Author : Orest Lastow; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air filtration; collection efficiency; aerosol technology; numerical modelling; fibrous filter; fiberfilter; aerosolteknik; luftrening;

    Abstract : A personal computer program, FiFi, that makes a real-time two-dimensional simulation of the dynamic deposition process of particles on one or two fibres, has been developed. The code has been used to numerically calculate the collection efficiencies of spherical particles on a clean single fibre. READ MORE

  5. 3. Tailoring fibre and paper properties using physical adsorption of polyelectrolytes

    Author : Andrew Marais; Lars Wågberg; Ulrica Edlund; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The adsorption of polyelectrolytes, both as monolayers and as multilayers, was investigated as an easy and non-expensive way of producing lignocellulosic fibrous materials with enhanced mechanical properties.In the first part of the work described in this thesis, the adsorption of a polyelectrolyte monolayer onto the surface of unbleached and unbeaten kraft pulp fibres with different kappa numbers was investigated.

  6. 4. Gut microbiota to counteract metabolic disorders and neuroinflammation : Impact of dietary factors and their potential to prevent Alzheimer’s disease

    Author : Nittaya Marungruang; Avdelningen för livsmedel och läkemedel; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer’s disease; gut microbiota; metabolic disorders; inflammation; neuroinflammation; lingonberries; dietary fibre; gut barrier; blood-brain barrier;

    Abstract : Alzheimer’s disease (AD) is the most common form of dementia. Increased accumulations of senile plaques and tangles are the known neuropathological hallmarks of AD. However, the exact triggers for such protein accumulations, leading to cognitive impairment and important morphological alteration in AD, are still elusive. READ MORE

  7. 5. Permeability modelling and particle deposition mechanisms related to advanced composites manufacturing

    Author : Markus Nordlund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Advanced composite materials reinforced by Non-Crimp Fabrics (NCFs) are becoming increasingly popular for high performance, light weight, complex structures, due to their high mechanical properties and relatively cheap production costs. These materials, not only improve the structural properties, but also induce great possibilities for reduced fuel consumptions for aircrafts and automotives, due to their high strength to weight ratio.
