  1. 16. Study of the Performance of Peat Moss Pyrolysis

    University essay from KTH/Materialens processteknologi

    Author : Yuming Wen; [2019]
    Keywords : peat moss; pyrolysis; bio-acids;

    Abstract : Peat moss, also called sphagnum, has become a big problem in many countries such as China and Sweden due to its high green-house gas emission from chemical and biological degradation. In this work, the performance of peat moss pyrolysis has been studied, to investigate the potential of application of peat moss pyrolysis on fuel and chemical production. READ MORE

  3. 17. Dose-response for predicting skin sensitization potency with the GARD®skin method

    University essay from Lunds universitet/Institutionen för immunteknologi

    Author : Olivia Eliasson; [2019]
    Keywords : Dose-response; In vitro assay; GARD; skin sensitization; allergic contact dermatitis; chemical sensitizers; hazard assessment; skin sensitization potency; immunotoxicology; Technology and Engineering; Biology and Life Sciences;

    Abstract : Allergic contacts dermatitis is a major health problem in the world and the disease is caused by a type IV hypersensitivity to a small chemical called a hapten. These substances are common in cosmetics, perfumes, pharmaceuticals and house-hold products, and risk factors include both inherent factors and frequent or high exposure. READ MORE

  5. 19. Trace element analysis based on neutron activation with coincident gamma ray detection

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Author : Jessica Delgado; [2017]
    Keywords : scintillator detectors; gamma ray; gamma radiation; spectrometer; neutron activation analysis; trace element; Physics and Astronomy;

    Abstract : In this work, six soil samples have been analyzed. The samples come from different sedimentary layers on Earth. They were previously studied with the objective to find the trace concentration of iridium, to correlate the increased concentrations of iridium with meteorite impacts that have occurred on Earth.
