   Sammanfattning : The aim of this work was to study atmospheric aerosols, focusing on the chemical composition, the morphology and the origin of the aerosol in the upper troposphere and lowermost stratosphere. An aerosol sampler was developed for this purpose. A new method for quantitative analysis of the major components of the aerosol, i.e. LÄS MER

   Sammanfattning : Pork is the most popular and consumed meat in Vietnam, and the preference among consumers for fresh and “warm” pork makes the traditional pork value chain dominate the pork industry. This thesis assessed microbial contamination in pork, then evaluated the technical and economic aspects of light-touch interventions in improving the safety of pork in the small-scale value chain.
