  1. 1. Topographic Control of Groundwater Flow

    Författare :Lars Marklund; Anders Wörman; Shulan Xu; Roy Haggerty; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Groundwater; Modeling; Topography; Spectral analysis; Fourier series; Exact solu-tions; Multi-scale; Grundvatten; Modellering; Topografi; Spektralanalys; Fourier serier; Analytisk lösning; Flerskalig; Hydrology; Hydrologi; Environmental engineering; Miljöteknik;

    Sammanfattning : Gravity is the main driving force for groundwater flow, and both landscape topography and geology distribute the effects of gravity on groundwater flow.  The groundwater table defines the distribution of the potential energy of the water. LÄS MER

  3. 2. Cross-functional brain imaging of attention, memory, and executive functions : Unity and diversity of neurocognitive component processes

    Författare :Petter Marklund; Lars Nyberg; Akira Miyake; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Human memory; executive functions; prefrontal cortex; sustained and transient neural activity; declarative long-term memory; attention; working memory; functional neuroimaging; cognitive control.; Psychology; Psykologi;

    Sammanfattning : The central theme of the present thesis revolves around the exploration of similarities and differences in brain activity patterns invoked by the component processes underlying mnemonic, executive and attentional functions. The primary aim was to identify and functionally characterize commonly recruited brain regions in terms of shared component processes, which has been a largely neglected area of research in cognitive neuroscience.

  5. 4. Implicit and explicit norm in contemporary Russian verbal stress

    Författare :Elisabeth Marklund Sharapova; Sven Gustavsson; Ludmila Ferm; Lars Steensland; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Slavic and Baltic languages - general; language norm; implicit norm; explicit norm; language normativisation; language normalisation; codification; Russian; stress; verbal stress; accentology; orthoepy; Slaviska och baltiska språk - allmänt; Slavic languages; Slaviska språk; Slaviska språk; Slavic Languages;

    Sammanfattning : The purpose of this thesis is to investigate norm in contemporary Russian verbal stress. In a first step the concept of norm is explored. It is shown that the criteria generally used in Russian for defining norm (correspondence to the language system, usage and authority/tradition/necessity) are not applied strictly. LÄS MER

  7. 5. Clinical Consequences of Axonal Injury in Traumatic Brain Injury

    Författare :Sami Abu Hamdeh; Niklas Marklund; Per Enblad; Lars Hillered; Andreas PhD Unterberg MD; Uppsala universitet; []
    Nyckelord :Traumatic brain injury; diffuse axonal injury; intracranial pressure; magnetic resonance imaging; amyloid-beta; tau; Neurokirurgi; Neurosurgery;

    Sammanfattning : Traumatic brain injury (TBI), mainly caused by road-traffic accidents and falls, is a leading cause of mortality. Survivors often display debilitating motor, sensory and cognitive symptoms, leading to reduced quality of life and a profound economic burden to society. LÄS MER
