2. 1. Reticulate Evolution in Diphasiastrum (Lycopodiaceae)

   Author : Sunniva Margrethe Due Aagaard; Niklas Wikström; Tom A. Ranker; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; admixture analysis; Bayesian clustering; Diphasiastrum; Feulgen DNA image densitometry; homoploid hybridization; Lycopodiaceae; phylogenetic analysis; polyploidy; reticulate evolution; Systematics and phylogenetics; Systematik och fylogeni; systematisk botanik; Systematic Botany;

   Abstract : In this thesis relationships and the occurrence of reticulate evolutionary events in the club moss genus Diphasiastrum are investigated. Diphasiastrum is initially established as a monophyletic group within Lycopodiaceae using non recombinant chloroplast sequence data. READ MORE

4. 2. Copy Number Analysis of Cancer

   Author : Markus Mayrhofer; Anders Isaksson; Simon Tavaré; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chromosomes; oncology; bioinformatics; Bioinformatik; Bioinformatics; Oncology; Onkologi; Clinical Genetics; Klinisk genetik;

   Abstract : By accurately describing cancer genomes, we may link genomic mutations to phenotypic effects and eventually treat cancer patients based on the molecular cause of their disease, rather than generalizing treatment based on cell morphology or tissue of origin.Alteration of DNA copy number is a driving mutational process in the formation and progression of cancer.

5. 3. Gene transfer by interspecific hybridization in bryophytes

   Author : Weerachon Sawangproh; Biodiversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; homozygote; heterozygote; admixture; single nucleotide polymorphism; STRUCTURE; PCoA; hybrid index; inbreeding; outbreeding; hybrid depression; heterosis; phylogeny; purging selection; genetic purging; genotype; phenotype; sympatry; allopatry;

   Abstract : The role of hybridization in evolution has been debated for more than a century regarding bryophytes (mosses, liverworts, and hornworts) as well as most other organisms. Bryophytes have haplodiplontic life cycles with a dominant haploid generation. READ MORE

6. 4. Conservation genomics in inbred Scandinavian wolves using bioinformatic methods

   Author : Linnéa Smeds; Hans Ellegren; Giorgio Bertorelle; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; conservation genomics; Canis lupus; bioinformatics; Y chromosome; admixture; genetic load; structural variation; GWAS; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Abstract : With the recent and unprecedented progress in retrieving DNA sequence information from a large number of individuals of any species, conservation genetic research has entered a new phase. Specifically, it has become possible to study how genomes of endangered species respond to reductions in population size. READ MORE

7. 5. Leaching of Hazardous Substances from Concrete Constituents and Painted Wood Panels

   Author : Åse Togerö; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thiocyanate; biocides; leaching; runoff; admixture; coatings; resin acids; blast furnace slag; toxic; fly ash; cement; tall oil; diffusion paints; concrete;

   Abstract : At a time of increased concern about environmental issues in the building sector, it is essential to know the environmental performance of different building materials. Knowledge of the possible release of hazardous substances in building materials is scarce, and these aspects have often been neglected in environmental assessment methods. READ MORE
