  1. 1. Volatiles of Conifer Seedlings : Compositions and Resistance Markers

    Författare :Astrid Kännaste; Anna-Karin Borg-Karlson; Anders Backlund; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Conifers; Norway spruce; Scots pine; Nalepella; Oligonychus ununguis; green leaf volatiles; terpenes; aromatics; benzenoids; SPME; induced defense reaction; Organic chemistry; Organisk kemi;

    Sammanfattning : Pine weevils cause major damage to newly planted conifer seedlings in reforestation areas. However, recent findings indicate that small (“mini”) seedlings, planted at the age of 7-10 weeks, are gnawed less by pine weevils than the larger, conventionally planted seedlings. LÄS MER

  3. 2. Ecology and Evolution of Resistance to Herbivory : Trichome Production in Arabidopsis lyrata

    Författare :Geir Løe; Jon Ågren; Kari Lehtilä; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Plant-animal interactions; herbivory; trichomes; plant resistance; plant defense; divergent selection; local adaptation; GLABROUS1; evolution; matrix population models; LTRE; Biologi; Biology; Biologi;

    Sammanfattning : In this thesis, I examine variation in occurrence and performance of glabrous and trichome-producing plants of the perennial herb Arabidopsis lyrata. I combine field studies and genetic analysis to (1) examine the function of trichomes as a resistance character in natural populations, (2) compare the magnitude of population differentiation in trichome-production and at putatively neutral marker loci, (3) examine the molecular genetic basis of trichome-production, and (4) quantify the effects of herbivore removal on population growth and relative performance of glabrous and trichome-producing plants.

  4. 3. Study of Resistance in Hepatitis C Virus Prior to Treatment with Direct Acting Antivirals

    Författare :Midori Kjellin; Johan Lennerstrand; Nina Weis; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hepatitis C; HCV; DAA; RAS; resistance-associated substitution; baseline resistance; NS5A; NS3; SVR; Medical Virology; Medicinsk virologi; Mikrobiologi; Microbiology; Infektionssjukdomar; Infectious Diseases;

    Sammanfattning : The rapid advancement of Hepatitis C (HCV) treatment presents a great challenge to clinicians in optimising therapy for their patients. Genotype (GT), efficacy, side-effects, drug combinations and treatment durations must be tailored to individual patients, considering comorbidities, degree of fibrosis, adherence and antiviral resistance.

  5. 4. Political geographies of region work

    Författare :Kristin Smette Gulbrandsen; Institutionen för kulturgeografi och ekonomisk geografi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Regions; Regionalisation; Political geography; Norway; Regioner; Regionalisering; Politisk geografi; Norge;

    Sammanfattning : Regionalisation processes and regionalist contestation have been the subjects of long-standing debates on state rescaling and political geographies of discontent. Similar dynamics are also present in Norway, where a recent regional reform has faced opposition along centre-periphery lines. LÄS MER

  7. 5. Distributions Of Fiber Characteristics As A Tool To Evaluate Mechanical Pulps

    Författare :Sofia Reyier Österling; Per Engstrand; Hans Höglund; Olof Ferritsius; Rita Ferritsius; Hans Ersson; Per Gradin; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber; fibre; fiber characteristics; fiber dimension; fiber properties; mechanical pulp; FiberLab; raw data; distribution; fiber wall thickness; BIN; bonding ability influence; bonding indicator; bonding ability; fiber width; fibrillation; collapse resistance; laboratory sheet; fiber analyzer; optical analyzer; TMP; CTMP; SGW; sheet model; prediction; fiber characterization; hydrocyclone; fractionation; kernel density estimation; KDE; diffusion mixing; acoustic emission; F0.90; Norway spruce; Picea abies;

    Sammanfattning : Mechanical pulps are used in paper products such as magazine or news grade printing papers or paperboard. Mechanical pulping gives a high yield; nearly everything in the tree except the bark is used in the paper. This means that mechanical pulping consumes much less wood than chemical pulping, especially to produce a unit area of printing surface. LÄS MER
