1. 1. 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

3. 2. Stress, sleep disturbance, and related ill-health : from prevalence and risk-factors to indicated interventions

   Författare :Per Höglund; Steven Nordin; Camilla Hakelind; Steven Linton; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Stress-related ill-health; Prevalence; Risk factors; Burnout; Insomnia; Non-experts; Low intensity psychological interventions; Primary care; Scalability; Indicated prevention.; klinisk psykologi; Clinical Psychology; epidemiologi; Epidemiology;

   Sammanfattning : With focus on stress-related ill-health and insomnia/sleep disturbance, the overall aim of this thesis was to determine severity and prevalence, risk factors and effectiveness of low-intensity group sessions. This was accomplished by taking epidemiological and quasi-experimental approaches. LÄS MER

4. 3. InGaAs-based quantum dots for infrared imaging applications : growth and characterisation

   Författare :Linda Höglund; Per-Olof Holz; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : In this thesis, results are presented from the development of quantum dot (QD) based infrared photodetectors (IPs). This includes epitaxial growth of QDs, investigations of the structural, optical and electronic properties of the QD based material as well as characterisation of the resulting components. LÄS MER

5. 4. Quantitative genetics of gene expression and methylation in the chicken

   Författare :Andrey Höglund; Dominic Wright; Per Jensen; Rie Henriksen; Kees van Oers; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In quantitative genetics the relationship between genetic and phenotypic variation is investigated. The identification of these variants can bring improvements to selective breeding, allow for transgenic techniques to be applied in agricultural settings and assess the risk of polygenic diseases.

7. 5. Growth and characterisation of InGaAs-based quantum dots-in-a-well infrared photodetectors

   Författare :Linda Höglund; Per-Olof Holtz; Mattias Hammar; Stefan Johansson; Sanjay Krishna; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material physics with surface physics; Materialfysik med ytfysik;

   Sammanfattning : This thesis presents results from the development of quantum dot (QD) based infrared photodetectors (IPs). The studies include epitaxial growth of QDs, investigations of the structural, optical and electronic properties of QD-based material as well as characterisation of the resulting components. LÄS MER
