  1. 21. Developement of a portable β-­‐ spectrometer for in situ measurements of Sr-­‐90 and Y-­‐90 using a plastic scintillator and a silicon photomultipler (SiPM).

    University essay from Lunds universitet/Medicinsk strålningsfysik, Lund; Lunds universitet/Sjukhusfysikerutbildningen

    Author : Daniel Krona; [2015]
    Keywords : Medicine and Health Sciences;

    Abstract : In the event of a nuclear weapon detonation or a power plant accident radionuclides will deposit on the ground. It is then important to identify and quantify the radionuclides to obtain information necessary for radiation protection efforts like relocation and decontamination. READ MORE

  3. 22. Time of Flight Spectroscopy of Photon Migration in Turbid Media

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

    Author : Johanna Paulsson; [2014]
    Keywords : Physics and Astronomy;

    Abstract : Light interacting with biological matter is dominated by light scattering; biological matter is turbid. In order not to harm the natural structure of biological matter, visible light can be used to investigate it, and to avoid the light being absorbed from e.g. READ MORE

  4. 23. Quality analysis of raw milk along the value chain of the informal milk market in Kiambu County, Kenya

    University essay from SLU/Dept. of Microbiology

    Author : Mattias Orregård; [2013]
    Keywords : Informal market; Kenya; Milk handling; Raw milk; Value chain;

    Abstract : Farmers, agents and shops were interviewed to elucidate the postharvest handling practices of raw milk on the informal milk market in Kiambu County, Kenya. Interviews were also conducted to ascertain the knowledge and precautions taken by the farmers to prevent the presence of antibiotic residues in the milk. READ MORE

  5. 24. Feed improvement by energy efficient storage using Pichia anomala inoculated ensiled cereal grain

    University essay from SLU/Dept. of Microbiology

    Author : Jenny Borling; [2010]
    Keywords : Cereal grain storage; microbial population; Feed hygiene; Moulds; Pichia anomala;

    Abstract : Borling, J. 2010. Preservation of moist crimped cereal grain can be achieved as a result of fermentation by lactic acid bacteria. Climatic variations make it difficult under practical farm conditions to harvest the grain at a moisture content (30-45%), suitable to ensure fermentation. READ MORE

  6. 25. An investigation of friction graphs ranking ability regarding the galling phenomenon in dry SOFS contact : (Adhesive material transfere and friction)

    University essay from Karlstads universitet/Fakulteten för teknik- och naturvetenskap

    Author : Harald Wallin; [2008]
    Keywords : galling; friction; adhesive contact; mild adhesive; severe adhesive; abrasive; flattening; SOFS; TNO; slider on flat surface; tribology; dry; lubricated; frictional heating; acceleration; plastic zone; contact pressure; pressure; phase transformation; morphology; seizure; scoring; scuffing; cohesive forces; classification; characteristic patterns; lump; sheet damage; på kletning; friction; kontakt tryck; värme; plogning;

    Abstract : The main purpose of this project is to investigate different tool steels in terms of their ability to withstand material transfer buildup, so-called galling, occurring in SMF (sheet metal forming) operations. The ability to withstand galling is vital to optimize cost-effectiveness and increase the work tool’s effective operational time. READ MORE
