1. 1. Heterogeneity-Induced Channelling, Flow-Wetted Surface, and Modelling of Transport in Fractured Rock

   Författare :Martin Larsson; Auli Niemi; Chin-Fu Tsang; VLADIMIR CVETKOVIC; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; channelling; flow-wetted surface; fractured rock; solute transport; groundwater modelling; groundwater; Hydrology; Hydrologi;

   Sammanfattning : Heterogeneities in fractured rock are found at all scales; from the scale of individual fractures, to the scale of fracture networks, and to the largest regional scales. These heterogeneities cause challenges for modelling and parameter estimation of flow and solute transport. LÄS MER

3. 2. A kinetic study of metabolite transfer in coupled two-enzyme reactions

   Författare :Henrik Pettersson; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Free diffusion; Enzyme kinetics; Channelling; Dehydrogenase; Fusion protein; Biochemistry; Proximity effect; metabolism; Biokemi;

   Sammanfattning : There are two fundamentally different ways by which a metabolite can be transferred between enzymes in metabolic pathways. If the two sequential enzymes cannot form a complex with each other, the metabolite must first be released from the producing enzyme to the reaction medium and then be transported to the consuming enzyme, via the reaction medium, by free diffusion.

4. 3. Mechanism of Metabolite transfer between Enzymes in Glycolysis and Connected Pathways

   Författare :Wilma Martinez Arias; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Channelling; Free-diffusion; Glycolytic pathway; Dehydrogenases; Enzyme kinetics; Biochemistry; Metabolite transfer mechanism.; Biokemi; Metabolism;

   Sammanfattning : The metabolite produced by one enzyme in a metabolic pathway can be transferred to the next enzyme in the pathway by free diffusion via solution or by channelling in an enzyme-enzyme complex without prior release of the metabolite to solution. While metabolite channelling is known to occur in systems where stable multienzyme complexes form, conflicting views have been expressed as to its existence in pathways involving "soluble" enzymes.

5. 4. Disturbances in Fixed-Bed Combustion

   Författare :Sven Hermansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; modelling; packed bed; bed; combustion; channelling; grate furnace;

   Sammanfattning : Conversion of solid fuels in fixed beds is a common method for heat and power production. A frequent fixed-bed technique in small to medium scale is combustion in grate furnaces. Grate furnaces are widely used in the industrial energy branch and appreciated for their stability and simplicity of control. LÄS MER

7. 5. Mirakel, mysterier och moraliteter. Från puritanism till New Age - en religionshistorisk studie av Helen Shucman och A Course in Miracles

   Författare :Pernilla Gardeberg; Centrum för teologi och religionsvetenskap; []
   Nyckelord :HUMANIORA; HUMANITIES; Helen Shucman; American religion; Puritan; Protestant; metaphysical; spiritualism; channelling; New Thought; Christian Science; A Course in Miracles; New Age; spirituality; mentalities;

   Sammanfattning : A Course in Miracles (ACIM) is a spiritual teaching that was said to be channelled by Helen Shucman during 1965-1972. Shucman received what she described as an inner dictation, which she wrote down in shorthand. Her collegue and friend; William Thetford was then copy-typing the text. LÄS MER
