    Sustainable pellet production saving lives

    The world needs more efficient energy systems based on renewable raw material, an equation not easily solved. At Karlstad University, research and education are in progress to find sustainable energy systems, for instance, through a project in which pellets replace charcoal in cooking solutions in Zambia, because cooking with charcoal as fuel leads to extensive deforestation as well as health hazards. Globally, more deaths are caused by air pollution at home than malaria, HIV and tuberculosis put together.

    “In this study we looked at twelve different available residual products for pellet production in Zambia and how these products interact in different combinations”, says Stefan Frodeson, lecturer in environmental and energy systems. “The study has led to the discovery of several different residual products from forestry and agriculture. Other important findings are also how the materials could be used to manufacture a product that meets the demands of production in Africa.”

    Archaeology of those who are invisible in history

    Landless crofters, the subaltern, and those who lost their land in inheritance cases. In the poor houses, in the city slums. What did it mean not to own land and the vital rights that were connected to it? How could crofters influence their lives or their financial situations? How do we find these “invisible” workers who rented rooms in the cities? These are the questions that researchers seek to answer through the research project “The Archaeology and Cultural Heritage of the Dispossessed.”

    The research project is a methods development project that will for instance suggest best practices for archaeological excavations, documentation and conservation. The goal is to contribute through knowledge of history, people and their material remains during the period of approximately 1700–1900.

    What happened to the hyped nanomaterials?

    Carbon based nano materials such as graphene and carbon nanotubes were predicted a brilliant future when they were discovered. But quality problems curb the development of new products. The problem is that it is difficult to analyse the crystal structure and there are no established standard methods for classifying the materials. But now, researchers at Karlstad University are close to a solution.

    ”Carbon atoms must sit perfectly in a well-organised crystal structure at precise distances, but they don’t in the commercially available materials on the market today,” says Krister Svensson, associate professor of physics.

    New project enhances cybersecurity in Europe

    Karlstad University is the only Swedish university participating in a new large European research and innovation project under Horizon 2020. The aim of the project is to enhance cybersecurity skills in Europe.

    “We have a high profile in security and integrity protection techniques. We see the fact that we were chosen as further proof of the excellence of our research,” says Simone Fischer-Hübner, professor of Computer Science at Karlstad University.

    New study programme in computer science

    From this autumn, Karlstad University is offering a new three-year study programme in computer science for those who like IT and programming, but who are not interested in studying physics, electronics or a lot of mathematics.

    “The programme is tailor-made for those who completed upper-secondary school programmes in Science and Technology,” says Tobias Pulls, coordinator of the new programme. “We want to take advantage of their existing knowledge of mathematics, so the programme only includes the most essential mathematics. This study programme is specifically for those interested in computer science.”

    Unique study on gaming and English vocabulary learning – time played matters more than the type of game played

    A large-scale study reveals that Swedish teenagers who spend a lot of time playing video games excel when it comes to knowing many words in English. Compared to their non-gaming peers, the gamers score significantly higher for particularly difficult words. The study also concludes that the time played is more important than the type of game played for predicting vocabulary scores. The fact that the study draws on multiple datasets collected from more than 1,000 students makes it unique in the field.

    Pia Sundqvist, associate professor in English at Karlstad University and the University of Oslo, is responsible for the study and somewhat surprised at its results.

    "I had expected gamers to know more words than non-gamers because we have seen this in previous small-scale studies from around the world, not only in Scandinavia. However, I was surprised to learn that the time they reported playing commercial-off-the-shelf games mattered more for their English vocabulary than what types of games they played", says Pia Sundqvist.
