  1. 1. The Vertical Distribution of Roots, Mycorrhizal Mycelia and Nutrient Acquisition in Mature Forest Trees

    Författare :Hans Göransson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant ecology; Växtekologi; isotopes; Root bioassay; Mixed stands; Picea abies; Fagus sylvatica; Nutrient uptake; Quercus robur; PLFA; Root distribution; Ectomycorrhiza;

    Sammanfattning : The vertical distribution of the nutrient uptake of Norway spruce (Picea abies (L.) Karst.), European beech (Fagus sylvatica L.) and pedunculate oak (Quercus robur L. LÄS MER

  3. 2. Cervical Radiculopathy: A Study With Selective Nerve Root Blocks

    Författare :Leif Anderberg; Neurokirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; orthopaedics; Contrast distribution; Nerve root block; Cervical radiculopathy; Kirurgi; traumatology; Treatment; ortopedi; traumatologi;

    Sammanfattning : Cervical radiculopathy is diagnosed by history, clinical examination of the patient and magnetic resonance imaging (MRI) of the cervical spine. In many of the patients undergoing this diagnostic strategy, the nerve root/roots responsible for the radicular pain is difficult to define as clinical examination and MRI investigation does not provide information enough.

  4. 3. Distribution and regulation of auxin in Arabidopsis root cells

    Författare :Sara Petersson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The plant hormone auxin (IAA) coordinates many of the important processes in plant development. For example, IAA is critical for normal embryogenesis, root development, cell elongation, and the tropic responses such as gravitropism and phototropism. LÄS MER

  5. 4. Ecology of nematophagous fungi in agricultural soils

    Författare :Lotta Persmark; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic farming; Fungistasis; Competition; Bacteria; Conidial traps; Rhizosphere; Seasonal variation; Distribution; Endoparasitic; Nematode; Nematode-trapping; Ecology; Ekologi;

    Sammanfattning : Nematophagous fungi possess various mechanisms for infecting nematodes, and are either obligate parasites or facultative saprophytes. Nematophagous fungi have a potential as biological control agents against plant- and animal-parasitic nematodes. LÄS MER

  7. 5. Testing Homogeneity and Unit Root Restrictions in Panels

    Författare :Johan Blomquist; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Non-stationary panels; Panel unit root tests; Cross-sectional dependence; Homogeneity testing;

    Sammanfattning : This thesis is divided into two distinct parts. The first part contains three chapters, co-authored with Joakim Westerlund, that deal with the analysis of unit root testing, and the second part consists of two chapters on slope homogeneity testing. LÄS MER
