  1. 16. Cardiovascular effects of diesel exhaust : mechanistic and interventional studies

    Author : Magnus Lundbäck; Anders Blomberg; Benoit Nemery; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; air pollution; diesel exhaust; nitrogen dioxide; endothelin-1; cardiovascular effects; exhaust particle trap; Lung diseases; Lungsjukdomar; lungmedicin; Lung Medicine;

    Abstract : Background: Air pollution is associated with negative health effects. Exposure to combustion-derived particulate matter (PM) air pollution has been related to increased incidence of cardiovascular and respiratory morbidity and mortality, specifically in susceptible populations. Ambient particles, with a diameter of less than 2. READ MORE

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

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

    Abstract : 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. READ MORE

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

    Author : Jonas Westin; Lars-Göran Mattsson; Lars Hultkrantz; KTH; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; 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;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE
