  1. 21. Genomic selection and genome-wide association studies to dissect quantitative traits in forest trees

    Författare :Biyue Tan; Pär K. Ingvarsson; Björn Sundberg; Harry X. Wu; Dario Grattapaglia; Xiao-Ru Wang; Leopoldo Sanchez; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Genomic prediction; genome-wide association study; additive effects; dominance effects; epistasis effects; realized relationship matrix; Eucalyptus grandis; Eucalyptus urophylla;

    Sammanfattning : The convergence of quantitative genetics of complex traits with genomic technologies is quickly becoming an innovative approach to explore fundamental genetic questions and also have practical consequences for implementations in tree breeding. In this thesis, I used genomic selection and genome-wide association studies (GWAS) to dissect the genetic basis of quantitative traits, i. LÄS MER

  3. 22. Welfare Effects of Transport Policies : an analysis of congestion pricing and infrastructure investments

    Författare :Jonas Westin; Lars-Göran Mattsson; Lars Hultkrantz; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; congestion charge; cost-benefit analysis; tax distortions; transport investment; transport policies; welfare effects; Economics; Nationalekonomi; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; SRA - Transport; SRA - Transport;

    Sammanfattning : Interactions between the transport market and other distorted markets, such as the labor market, can have a large impact on the overall welfare effect of a road pricing policy or a congestion charge. Many road pricing studies therefore try to incorporate effects from other distorted markets in the analysis. LÄS MER

  4. 23. Experimental Evolution : and Fitness Effects of Mutations

    Författare :Anna Knöppel; Dan I Andersson; Stanley Maloy; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Experimental evolution; Fitness effects; mutations; S20; fis; ribosome; horizontal gene transfer; adaptation; synonymous mutations; Mikrobiologi; Microbiology;

    Sammanfattning : Bacteria have small, streamlined genomes and evolve rapidly. Their large population sizes allow selection to be the main driver of evolution. With advances in sequencing technologies and precise methods for genetic engineering, many bacteria are excellent models for studying elementary questions in evolutionary biology. LÄS MER

  5. 24. Congestion Charging in Urban Networks : Modelling Issues and Simulated Effects

    Författare :Ida Kristoffersson; Leonid Engelson; Otto Anker Nielsen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport Modelling; Congestion Charging; Departure Time Choice; Dynamic Traffic Simulation; Welfare Effects; Equity;

    Sammanfattning : One of the major challenges cities face today, in their development towards sustainable urban areas, is the need for an efficient and environmentally friendly transport system. This transport system should manage to tie together the city without strong adverse impact on urban environment, air-quality and climate change. LÄS MER

  7. 25. Obsessive-compulsive disorder, serotonin and oxytocin : treatment response and side effects

    Författare :Mats B. Humble; Ingemar Engström; Lars von Knorring; Lars Kjellin; Lil Träskman-Bendz; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adverse effects; Obsessive-compulsive disorder; Orgasm; Oxytocin; Randomised controlled trial; Rating scale; Response prediction; Serotonin; Serotonin uptake inhibitors; Sexual function; Psychiatry; Psykiatri;

    Sammanfattning : Obsessive-compulsive disorder (OCD), with a prevalence of 1-2 %, frequently leads a chronic course. Persons with OCD are often reluctant to seek help and, if they do, their OCD is often missed. This is unfortunate, since active treatment may substantially improve social function and quality of life. LÄS MER
