    Sammanfattning : Processes in the environment are often complex and the description and prediction of the behaviour of environmental pollutants requires sophisticated methodology including multidimensional technology. Multivariate statistical methods including principal component analysis (PCA) and partial least squares projection to latent structures (PLS) were used to characterise several nitroaromatic compounds according to a large number of chemical and physical properties.

    Sammanfattning : For teachers and students to be able to make informed decisions about how to best improve learning, it is important to compare learning strategies that are known to be effective. Both multimedia learning, based on the notion that individuals learn better from words and pictures presented together than from words alone, and retrieval practice, based on the idea that retrieving knowledge from the memory is an active process that has a beneficial impact on learning, have been found robust learning strategies in earlier research.
