    KaU students reach the semifinals in a national cyber security contest

    When the Swedish Defence University and The Swedish Civil Contingencies Agency (MSB) arranged the contest Cyber Challenge on Thursday, 6 February, 14 teams of university students vied to prove that they could act as the best experts on national security. The team from Karlstad called TrollControl performed well and reached the semifinals.

    “It was an enjoyable experience and we were really challenged to make important decisions quickly, says Michaela Padden,” a doctoral student in Political Science and one of the TrollControl team members. “However, I think we did a good job and our team communicated well.”

    Forest fertilisation with paper mill residues

    Research at Karlstad University shows that sludge and ashes as paper mill residues can be used as effective fertiliser. This involves biochar, that is, carbon from organic material returned to the forest and thus closing the cycle.

    "Biochar has many beneficial effects on the environment," says Maria Sandberg, senior lecturer in environment and energy systems and research leader for the project. "Our lab experiments show that by enriching biochar we can produce a very effective fertiliser for forest plants. If we bring biochar back to the forest, it will remain stable for a long time. In this way, carbon is bound up and there is less carbon dioxide in the atmosphere, which counteracts global warming."

    Continued research in weightless state

    Solar cell research at Karlstad University has been granted further funding from the Swedish National Space Agency. This means a new opportunity to carry out experiments in an aeroplane in which micro-gravitation is created for the purpose of better understanding how the structure of the active layer of the solar cell is formed.

    ”It’s extremely satisfying to get an extension of this high-risk project from the National Space Agency”, says Jan van Stam, professor of physical chemistry at Karlstad University. ”We have, moreover, once again successfully passed the vetting procedure and received permission from ESA, European Space Agency, to carry out our new experiments during parabolic flights in autumn 2020. This is tantamount to a confirmation that we are on the right track and have put Karlstad University on the map in regard to research with paramount importance internationally.”

    Karlstad University researchers have made the anonymity network Tor safer

    The anonymity network Tor, used daily by millions of users around the world, is important for people in vulnerable situations, for instance in order to avoid surveillance or control. Two Karlstad University researchers have now identified flaws in Tor’s anonymity function and contributed to technologies that make the network safer for users.

    The purpose of Tor is to allow users to surf the internet anonymously without information about visited webpages being registered. Despite this function, the flaws that the researchers have detected could make it possible in certain cases for attackers to see what webpages a user has visited.

    International collaboration gives new research ideas

    Working together with other researchers in a cross-country collaboration makes you more open to develop new ideas and look at things from another angle, says Swedish researcher Annika Fredén, currently working at the University of Montreal.

    Annika Fredén is a Senior Lecturer in Political Science at Karlstad University, and also Principal Investigator in the program WASP-HS. We asked her to give a view on international research collaboration.

    Could you tell a bit more about your stay in Montreal?

    Mathematicians helped the industry with previously unsolved problems

    On 10 December, the third Mathematics Meets Industry Day (MIMM®) was arranged at Karlstad University. Representatives from Kongsberg, Region Värmland, and Uddeholm participated, and together with upper secondary school students, university students, and researchers they tried to find mathematical solutions for previously unsolved problems.

    “The purpose of this day is to demonstrate to the industry the benefits of working with mathematicians. We also want to show upper secondary school students how much fun applied mathematics is and how many potential career paths it can offer,” says Elisabeth Mellroth, a PhD in Pedagogical Work and a teacher at the Sundsta-Älvkulle upper secondary school, who arranged the event together with Adrian Muntean, Professor of Mathematics at Karlstad University.
