  2. 1. Game of crops : genetic composition and adaptation of seed orchard crops

    Author : Alisa Heuchel; Xiao-Ru Wang; David Hall; Ulfstand Wennström; Jaroslaw Burczyk; Umeå universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; seed orchards; GBS; linear deployment; tree improvement; genetic diversity; adapation; topgrafting; Scots pine; Norway spruce; improved reforestation material; field performance; flowering stimulation; fertility variation; Genetics; genetik; environmental science; miljövetenskap;

    Abstract : Orchard populations are artificial and intensively managed populations of elite, best-performing trees that are established for mass production of genetically improved seeds. Seed orchards connect cycles of selection, breeding, and testing of plus-trees with the deployment of the improved seeds at the operational plantations. READ MORE

  4. 2. Detecting, Identifying and Managing Sources of Variation in Production and Product Development

    Author : Alexander Chakhunashvili; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robust Design Methodology; Variation Mode and Effect Analysis VMEA .; Key Product Characteristics; Statistical Process Control SPC ; sources of variation;

    Abstract : It is well known that customers have varying needs and wants and thus expect to have a broad spectrum of products to choose from. However, they hardly tolerate variation in products produced to the same specifications. READ MORE

  5. 3. Tracing and apportioning sources of dioxins using multivariate pattern recognition techniques

    Author : Anteneh Assefa; Mats Professor; Karin Professor; Paul Professor; Patrik Andersson; Shigeki Masunaga; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polychlorinated dibenzo-p-dioxin; polychlorinated dibenzofuran; positive matrix fac- torization; PMF; principal component analysis; PCA; Baltic Sea; sediment core; PCDD F; sources; marine; fish; environmental half-live; peak year; peak level; temporal trend; spatial variation; coastal; offshore; chemical fingerprint; Environmental Science; miljövetenskap;

    Abstract : High levels of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) in edible fish in the Baltic Sea have raised health concerns in the Baltic region and the rest of Europe. Thus, there are urgent needs to characterize sources in order to formulate effective mitigation strategies. READ MORE
