  1. 1. Desert Plants and Deserted Islands : Systematics and Ethnobotany in Caryophyllaceae

    Författare :Anneleen Kool; Mats Thulin; Gudrun Kadereit; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; BEAST; Corrigiola; DNA barcoding; Morocco; Pollichia; Polycarpon; Polycarpaea; RAxML; Sanctambrosia; Spergula; Spergularia; Sphaerocoma;

    Sammanfattning : Background. Caryophyllaceae is a large and cosmopolitic flowering plant family, however the systematics of many of its basal groups has been unclear, due to a lack of unambiguous morphology. Some members of Caryophyllaceae are used medicinally, e.g. LÄS MER

  2. 2. Influence of electrode material and stochastic factors on the performance and microbial community assembly in microbial electrochemical systems

    Författare :Marie Abadikhah; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microbial community assembly; bioanode; biocathode; biochemical system;

    Sammanfattning : Microbial electrolysis cells (MECs) are systems with microbial communities in the form of biofilms on electrode surfaces. The electrogenic bacteria in the anode biofilm act as catalysts for the oxidization of organic compounds, leading to release of electrons, generation of electrical current, and production of hydrogen and methane at the cathode.

  3. 3. Botanical Repellents and Pesticides Traditionally Used Against Haematophagous Invertebrates in Lao PDR

    Författare :Chanda Vongsombath; Thomas Jaenson; Raimondas Mozuraitis; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ethnobotany; fly larvae; Lao PDR; medical entomology; mosquito repellents; myiasis; plant-based insecticides; terrestrial leeches; Haemadipsidae; Systematics and phylogenetics; Systematik och fylogeni; Organism biology; Organismbiologi; Biologi med inriktning mot systematik; Biology with specialization in Systematics;

    Sammanfattning : Haematophagous parasites and disease vectors such as leeches, ticks, mites, lice, bed bugs, mosquitoes, and myiasis-causing fly larvae are common health problems in Lao Peoples Democratic Republic (Lao PDR). A main aim of my field work in Lao PDR in 2006-2010 was to document traditional knowledge among different ethnic groups about plants that people use to repel or to kill blood-feeding invertebrates.

    Sammanfattning : The Laboulbeniales is an order of enigmatic ascomycete fungi that are obligate microscopic parasites of arthropods, which are usually non-detrimental. They typically display a high degree of host specificity, and the genus Coreomyces, which is the recurring theme of this thesis, is no exception. LÄS MER
