  1. 11. BVOC emission variability for Norway spruce (Picea abies) in Hyltemossa, Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Alexandra Arnsteg; [2022]
    Keywords : BVOC; isoprene; monoterpenes; induced emission; light dependency; temperature; Norway spruce.; Earth and Environmental Sciences;

    Abstract : Biogenic volatile organic compounds (BVOC) are known as hydrocarbons emitted into the atmosphere from the biosphere. They have physiological and ecological functions such as communication within the plant and plant – plant, protection against environmental stress factors and defense against herbivores attack.

  3. 12. MICROCLIMATE FRAMES FOR PAINTINGS ON CANVAS A literature review with a case study from Nationalmuseum

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Sofia Lundsten; [2021-10-28]
    Keywords : Microclimate frames; preventive conservation; humidity buffering;

    Abstract : The use of microclimate frames for paintings has become more common in the past decades, and it is a good way of protecting climate sensitive paintings during transport, loans, and exhibitions. This study is a literature review that aims to describe the overall practice of mounting canvas paintings in microclimate frames, as well as describe practices at Nationalmuseum, Sweden’s largest art gallery, in more detail.

  4. 13. Anaerobic Co-digestion of steam pretreated wheat straw and sewage sludge

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Virginia Tosi; [2021]
    Keywords : Anaerobic co-digestion; wheat straw pretreatment; nutrients availability; OLR; VFA acumulation; Biotechnology; Technology and Engineering;

    Abstract : Anaerobic digestion (AD) of wastes and residues is a widely applied and explored process. However, when the process is not optimized, inadequate concentrations of nutrients and inhibitory compounds are common and can lead to low maximum organic loading rates and increased risk of process problems, low organic dry solids degradation rate and reduced methane yields.

  5. 14. Optimizing Sample Dissolution Methods of Low Water Soluble Intermediate Organic Compounds to Support Environmental Risk Assessment during Active Pharmaceutical Ingredient Manufacturing.

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Warda Mohammed; [2021]
    Keywords : Active pharmaceutical ingredient; API; total organic content; TOC; chemical oxygen demand COD; biological oxygen demand; BOD; Microtox; octanol-water partition coefficient; Kow; solubility.;

    Abstract : This project focus on investigating the dissolution of low water-soluble intermediate organic compounds called active pharmaceutical ingredients (API) and organic substances that are manufactured by a pharmaceutical company, Cambrex Karlskoga in Sweden. Several dissolution methods were used and evaluated using methods including total organic carbon (TOC), chemical oxygen demand (COD), biochemical oxygen demand (BOD) and Microtox toxicity test.

  6. 15. Växt-växtbaserad kommunikation : hur sortblandningar påverkade tillväxten hos vårkorn

    University essay from SLU/Dept. of Ecology

    Author : Alexander Pettersson; [2021]
    Keywords : allelobios; allelopati; flyktiga organiska substanser; vårkorn;

    Abstract : Växter utgör grunden för många ekosystem och näringskedjor. Som platsbundna organismer behöver växter kunna anpassa sig efter de rådande förutsättningarna kring växtplatsen. Växter anpassar sig inte bara efter abiotiska faktorer, utan även stress från skadegörare och andra växter spelar en stor roll för en växtens överlevnad. READ MORE
