  1. 11. Interactions between plant pathogens and their implications for crop protection

    Kandidat-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Ayano Tanaka; [2021]
    Nyckelord :disease complex; nteraction; antagonism; synergism; Fusarium spp;

    Sammanfattning : One plant may often be infected by more than one pathogen species. It is assumed that species which exploit the same resource have the potential to affect each other. Plant diseases where more than one pathogen is involved in the development of infection are usually termed as ¨disease complex¨. LÄS MER

  3. 12. Nitrogen Without Oxygen : The effect of ferroalloys added after vacuum treatment on cleanliness of nitrogen-alloyed tool steel

    Master-uppsats, KTH/Materialvetenskap

    Författare :Leo Nilsson Hultén; [2021]
    Nyckelord :Tool steel; Electro-Slag Remelting ESR; Nitrogen Alloying; Ferroalloys; Nonmetallic Inclusions NMI; Verktygsstål; Elektroslaggomsmältning ESR; Kvävelegering; Ferrolegeringar; Ickemetalliska Inneslutningar NMI;

    Sammanfattning : Nitrogen-alloyed tool steel is made at Uddeholms AB by adding high-nitrogen ferroalloy after vacuum degassing where introduced impurities are hard to remove. In this thesis two types of high-nitrogen ferrochromium are compared, a solid version and a powder cored wire. LÄS MER

  4. 13. Cardiovascular effects of exposure to biodiesel exhaust

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Youna Marc-Derrien; [2021]
    Nyckelord :photoplethysmography; electrocardiography; signal processing; pulse decomposition analysis; heart rate variability; pulse transit time; biodiesel; arterial stiffness; Technology and Engineering;

    Sammanfattning : Context: Urban air pollution is considered a significant factor contributing to increased respiratory and cardiovascular mortality in cities. Many studies focused on the relationship between exposure to diesel exhaust and human health effects, demonstrating the toxicity of such gases. LÄS MER

  5. 14. Exploring predictive capacity of preterm neonatal characteristics on long-term development of language

    Kandidat-uppsats, Uppsala universitet/Institutionen för psykologi; Uppsala universitet/Forskargrupper (Inst. för kvinnors och barns hälsa)

    Författare :Eric Andersson; [2021]
    Nyckelord :Prematurity; Antenatal steroids; Language development; Long-term; Mother’s education;

    Sammanfattning : To explore the predictive capacity of ante, neo and postnatal characteristics on long-term language development in the prematurely born a prospective cohort design was used. Utilizing a cohort of prematurely born children to be assessed on their 12th birth year and collecting data on the complications associated with their prematurity as well as their mother’s characteristics.

  7. 15. Partial denitrification as nitrite provider for mainstream anammox

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Felix Wallin Holmin; [2020]
    Nyckelord :Water engineering; Environmental engineering; Mainstream anammox; Partial denitrification; PDA; MBBR; Nitrogen removal; Vattenförsörjningsteknik; Avloppsteknik; Technology and Engineering;

    Sammanfattning : In traditional wastewater treatment, nitrogen is removed through the biological process combination of nitrification and denitrification. Although it is a well-established method, the need for aeration and possible addition of an external carbon source results in it being an energy-negative and costly process, thus making alternative methods for nitrogen removal compelling to examine.
