  1. 6. Renewable Composites Prepared from Biobased Thermoset Resins

    Författare :Dan Åkesson; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Renewable; natural fibre; composite; biobased thermoset resin;

    Sammanfattning : In our efforts to create a more sustainable society, several researchers have tried to prepare composites from renewable materials in recent years. The use of natural fibres for reinforcement of composites has been relatively well studied. LÄS MER

  3. 7. Plant-Derived Chemicals as Tick Repellents

    Författare :Samira Sadek Garboui; Thomas Jaenson; Katinka Pålsson; Raimondas Mozuraitis; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ixodes ricinus; plants; essential oils; tick repellent; Sweden; Biology; Biologi;

    Sammanfattning : Ixodes ricinus is the main vector of Lyme borreliosis and Tick-borne encephalitis in Europe. Repellents provide a practical means of protection against tick bites and can therefore reduce transmission of tick-borne diseases. LÄS MER

  4. 8. Allergenic Oxidation Products from Fragrance Terpenes. Chemical Analysis and Determination of Sensitizing Potency

    Författare :Johanna Rudbäck; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Autoxidation; Contact allergy; Essential oils; Fragrances; Hydroperoxides; Ionization techniques; Mass spectrometry; Prehapten; Sensitization; Skin; Structure-activity relationships; Terpenes;

    Sammanfattning : The ubiquitous presence of fragrance compounds in consumer products has resulted in a high frequency of contact allergy to fragrances in the population. For prevention purposes and according to EU regulations, cosmetics must be labeled when containing the most prominent fragrance allergens in concentrations exceeding 0. LÄS MER

  5. 9. Targets and strategies for drug development against human African sleeping sickness

    Författare :Farahnaz Ranjbarian; Anders Hofer; Staffan G. Svärd; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; T. brucei thymidine kinase; T. brucei methylthioadenosine phosphorylase; FANA-A purine nucleoside analogues; essential oils;

    Sammanfattning : Trypanosoma brucei is a causative agent of African sleeping sickness. It is an extracellular parasite which circulates in the blood, lymph and eventually invades the central nervous system. LÄS MER

  7. 10. Light-Induced Routes to Sustainable Biocrudes for Fuels and Lubricant Oils

    Författare :Leandro Cid Gomes; Henrik Ottosson; Norbert Hoffmann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aviation fuels; triplet sensitization; photoacid; renewable energy; photochemistry; Kemi; Chemistry;

    Sammanfattning : Fossil-based hydrocarbons are at present the ideal compounds for jet fuels and lubricant oils, so their replacement by novel technologies is not easy. Instead, sustainable routes to hydrocarbons, such as sunlight-driven processes, are desired to reduce the environmental impact by the transport sector. LÄS MER
