  1. 1. Lake bathymetry as driver of salmonid population size structure and biomass

    Författare :Sven Norman; Pär Byström; Karin A. Nilsson; Jan Karlsson; Per-Arne Amundsen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lake bathymetry; habitat-specific resource production; ontogenetic niche shifts; size structure; Arctic char; brown trout; populationsbiologi; Population Biology; Limnology; limnologi; zooekologi; Animal Ecology;

    Sammanfattning : Most fish species undergo ontogenetic niche shifts from feeding on pelagic zooplankton, to larger benthic invertebrates and in some cases also to fish. These ontogenetic niche shifts have strong impact on the interactions within and between species, with effects on individual growth, population abundance and food web dynamics. LÄS MER

  3. 2. Bäst i klassen? : Lärare och elever i svenska och europeiska policytexter

    Sammanfattning : This thesis takes its departure in the recent criticism directed to the Swedish school system and its schools, teachers and pupils, but especially the epidemic of policies produced in order to develop and improve Swedish schools, in particular after the change of government in 2006. The general aim of this thesis is to study how teachers and pupils are represented, and thus constructed, regulated and positioned in a number of current key policy texts. LÄS MER

    Sammanfattning : In March 1809, when Sweden was yet again at war, part of its Western Army staged a revolt against Gustav IV Adolf that spelled the end of royal absolutism. The thesis shows how, in a turbulent period in European history marked by revolution and the Napoleonic wars, an army of several thousand men could successfully revolt and march from their positions in the county of Värmland clean across their own country to Stockholm, where they instigated a change of regime.

  5. 4. Comorbidity and vascular risk factors  associated with idiopathic normal pressure hydrocephalus : the INPH-CRasH Study

    Författare :Hanna Israelsson Larsen; Jan Malm; Anders Eklund; Norman Relkin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hydrocephalus; normal pressure; vascular disease; vascular risk factors; elderly; depression; case control study; epidemiology; dementia; vascular dementia; small vessel disease; cerebrovascular disease; transient ischemic attack; Neurology; neurologi;

    Sammanfattning : Idiopathic normal pressure hydrocephalus (INPH) is a dementia treatable by insertion of a cerebrospinal fluid shunt. It has been suggested that INPH has similar pathophysiological mechanisms as cerebrovascular disease, but the vascular risk factor (VRF) profile of INPH patients has not been assessed using a modern epidemiological approach.
