  1. 1. Phylogenetic and taxonomic studies within Arthonia Ach. (Ascomycetes, Arthoniales)

    Detta är en avhandling från Stockholm : Botaniska institutionen

    Författare :Rikard Sundin; Stockholms universitet.; [1999]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology Organism biology Systematics and phylogenetics; NATURVETENSKAP Biologi Organismbiologi Systematik och fylogeni; Plant Systematics; växtsystematik;

    Sammanfattning : The taxonomy and phylogeny of the genus Arthonia was analysed. As a first step, a phylogenetic analysis was performed to test the monophyly of some of the infrageneric groups suggested by earlier authors. The results strongly support that Arthonia, Arthothelium and Arthoniaceae are paraphyletic. LÄS MER

  2. 2. Treatment of domestic wastewater using microbiological processes and hydroponics in Sweden

    Detta är en avhandling från Stockholm : KTH

    Författare :Anna Norström; KTH.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; biological; hydroponics; microbial composition; nitrogen; organic matter; phosphorus; small scale; theoretical energy requirements; wastewater treatment.; Mikrobiologi; NATURAL SCIENCES Biology Organism biology Microbiology; NATURVETENSKAP Biologi Organismbiologi Mikrobiologi;

    Sammanfattning : Conventional end-of-pipe solutions for wastewater treatment have been criticized from a sustainable view-point, in particular regarding recycling of nutrients. The integration of hydroponic cultivation into a wastewater treatment system has been proposed as an ecological alternative, where nutrients can be removed from the wastewater through plant uptake; however, cultivation of plants in a temperate climate, such as Sweden, implies that additional energy is needed during the colder and darker period.

  3. 3. Microalgae - future bioresource of the sea?

    Detta är en avhandling från Växjö : Linnaeus University Press

    Författare :Martin Olofsson; Linnéuniversitetet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microalgae; algal cultivation; bioresource; bioenergy; CO2 mitigation; multi-species community approach; seasonal variation; Akvatisk ekologi; Aquatic Ecology; Bioteknik; Biotechnology; Environmental technology; Miljöteknik;

    Sammanfattning : Unicellular microalgae are a renewable bioresource that can meet the challenge forfood and energy in a growing world population. Using sunlight, CO2, nutrients,and water, algal cells produce biomass in the form of sugars, proteins and oils, allof which carry commercial value as food, feed and bioenergy. LÄS MER

    Sammanfattning : Environmental factors influence species and habitats on multiple scales creating a mosaic of distribution patterns. Studying factors shaping these patterns are central to our understanding of population dynamics and ultimately ecosystem functioning. LÄS MER

  5. 5. Nutritional Properties of Liquid Oats as Affected by Processing and Storage

    Detta är en avhandling från Lund University

    Författare :Huanmei Zhang; Lunds universitet.; Lund University.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biotechnology; Antioxidants; Avenanthramides; Biological value; Iron absorption; Fatty acids; Processing; Minerals; Vitamins; Storage; Stability; Nutritional properties; Oats; Beverage; Bioteknik;

    Sammanfattning : The cholesterol-lowering effects of oats have led to an increasing interest in them on the food market. Liquid oats has emerged as a new way of consuming oats and has become a commercial product. LÄS MER
