  2. 11. On pressure-driven Hele-Shaw flow

    Author : Salvador Manjate; Peter Wall; John Fabricius; Johan Byström; Niklas Lundström; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Mathematics; Tillämpad matematik;

    Abstract : The present licentiate thesis is devoted to the rigorous derivation of the equations governing thin-film flow of incompressible Newtonian and non-Newtonian fluids. More precisely, we consider flow in a generalized Hele-Shaw cell, which is a thin three-dimensional domain confined between two surfaces connected by cylindrical obstacles of various shapes.

  4. 12. Glutamate Turnover and Energy Metabolism in Brain Injury : Clinical and Experimental Studies

    Author : Carolina Samuelsson; Elisabeth Ronne-Engström; Lars Hillered; Eva Kumlien; Carl-Henrik Nordström; Uppsala universitet; []
    Keywords : Neurosciences; glutamate; glutamine; lactate; pyruvate; microdialysis; GLT-1; energy metabolism; intracranial pressure; cerebral perfusion pressure; subarachnoid hemorrhage; ischemia; epilepsy; Neurovetenskap;

    Abstract : During brain activity neurons release the major excitatory transmitter glutamate, which is taken up by astrocytes and converted to glutamine. Glutamine returns to neurons for re-conversion to glutamate. This glutamate-glutamine cycle is energy demanding. READ MORE

  5. 13. Form and Function of Coastal Areas

    Author : Dan Lindgren; Andreas Bryhn; Lars Håkanson; Lars Brydsten; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coastal areas; morphometry; geographic information systems; GIS; ecological value; wave exposure; sediment; bottom dynamic conditions; mass balance modeling; Other earth sciences; Övrig geovetenskap; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

    Abstract : Coastal waters have high biological productivity and provide goods and services with a high monetary value. Coasts are used by many different stakeholders and are often densely populated. READ MORE

  6. 14. A pressure coupled Representative Interactive Linear Eddy Model (RILEM) for heavy-duty truck engine combustion simulations

    Author : Nidal Doubiani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Representative interactive linear eddy model; multiple LEM lines; turbulent chemistry interaction; pressure coupling; pollutants formation.;

    Abstract : Internal combustion engines (ICE) are frequently debated due to their environmental consequences. Although the switch to electromobility is currently happening for light and medium-duty vessels, the transition for ships and heavy-duty trucks is more complex. The primary problem in the shift is the incapability of matching the range of ICE. READ MORE
