    University essay from Umeå universitet/Tandläkarutbildning

    Author : Emma Påhlson; Alexander Bergdahl; [2020]
    Keywords : ;

    Abstract : ABSTRACT Aim: To understand endodontic infections and their prognosis knowledge of which bacteria are present, viable, and part of perpetuating the late stages of the infection. The aim of this study was to investigate three different methods for mapping the composition of the microbiota in infected root canals. READ MORE

  4. 3. Possible unexpected peaks from oil drop size measurements in milk

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Laura Schalkwijk; Rodrigo Olmedo Sotomayor; [2020]
    Keywords : laser diffraction; oil droplet size; milk; pasteurised milk; unexpected peaks; mastersizer; food engineering; livsmedelsteknik; Technology and Engineering;

    Abstract : The shelf life of milk is amongst others dependent on the size of the oil droplets. These droplets can be measured using the laser diffraction (LD) technique. LD is a popular technique to measure particle size distributions (PSD) that has an outstanding broad measuring range capability, is easy-to-use and has a high reproducibility. READ MORE

  5. 4. Selection bias when estimating average treatment effects in the M and butterfly structures

    University essay from Umeå universitet/Statistik

    Author : Joakim Wallmark; [2019]
    Keywords : ;

    Abstract : Due to a phenomenon known as selection bias, the estimator of the average treatmen teffect (ATE) of a treatment variable on some outcome may be biased. Selection bias, caused by exclusion of possible units from the studied data, is a major obstacle to valid statistical and causal inferences. READ MORE

  6. 5. Analyzing microplastics in soils : Evaluating canola oil extractions

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Anna Bottone; [2019]
    Keywords : Microplastics; extraction recovery; OEP method; organic-rich soils;

    Abstract : Small fragments of artificial polymers (microplastics, MPs) has been reported for multiple environmental matrices from our planet. The omnipresent existence of these microplastics even in remote polar areas have raised concern about their potential environmental impacts and created a need for effective and standardized analytical methods targeting their detection in environmental samples.
