1. 1. Dispersion of wood fuel in a stationary fluidized

   Författare :Fredrik Niklasson; Chalmers tekniska högskola; []

3. 2. Lateral mixing of solids in bubbling fluidized beds – experimental quantification

   Författare :Erik Sette; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solids cross-flow; lateral dispersion; Solids mixing; fluid-dynamic scaling;

   Sammanfattning : For solid fuels, thermochemical conversion processes such as combustion and gasification are especially suitable to be carried out in fluidized bed units because of the relatively high mixing rates, fuel flexibility and the possibility to use active bed material to enhance process efficiency. Fuels such as biomass and waste, which are commonly used in fluidized beds, are characterized by volatile contents much higher than what is found in fossil fuels such as coal. LÄS MER

4. 3. Transverse Chromatic Aberration and Vision: Quantification and Impact across the Visual Field

   Författare :Simon Winter; Linda Lundström; Stephen Burns; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transverse chromatic aberration; lateral chromatic aberration; visual optics; peripheral vision; central vision; dispersion; ophthalmic optics and devices; optical effects on vision; retinal imaging; myopia; human eye; Fysik; Physics;

   Sammanfattning : The eye is our window to the world. Human vision has therefore been extensively studied over the years. However, in-depth studies are often either limited to our central visual field, or, when extended to the periphery, only correct optical errors related to a narrow spectrum of light. LÄS MER

5. 4. SOLIDS MIXING IN BUBBLING FLUIDIZED BEDS

   Författare :Erik Sette; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid-dynamic scaling; Solids mixing; lateral dispersion; solids cross-flow;

   Sammanfattning : For solid fuels, thermochemical conversion processes such as combustion and gasification are especially suitable to be carried out in fluidized bed units because of the relatively high mixing rates, fuel flexibility and the possibility to use active bed material to enhance process efficiency. Mixing of fuel is important to ensure complete conversion and reduced emissions of unburnt material. LÄS MER

7. 5. Biophysical studies of cell membrane receptors for the growth factors PDGP and EGF : Aspects on lateral and aggregation

   Författare :Pia Ljungquist-Höddelius; Carl-Henrik Heldin; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : When extracellular growth factors bind to their specific cell surface receptors, they elicit a cascade of biochemical events, including tyrosine kinase-mediated phosphorylation and changes in intracellular free ca2+, leading to cell differentiation and proliferation. However, direct effects of ligand-binding on the receptors are poorly understood. LÄS MER
