Internalizing climate education, political and societal incentives are instrumental to reduce flying – new research finds. Air travel accounts for a major share of individual greenhouse gas emissions. A transatlantic round trip adds up to 1.6 tons of carbon dioxide equivalent emission, which is the entire annual carbon budget of a person to maintain a sustainable life. However, the air travel sector is rapidly growing and has almost doubled during the last decade.
A virtual paper-making machine makes it possible to test run and optimise operations without costly downtime in the industry. New research at Karlstad University saves money and spares the environment. ”It is now possible to run the paper-making process virtually, without expensive equipment, to identify the optimal settings for each machine,” says Björn Sjöstrand, who recently submitted his doctoral thesis in chemical engineering at Karlstad University.
Karlstad Business School has qualified for a final review by AACSB, a non-profit organisation that works with quality enhancement and accreditation of business schools around the world. The review will be performed in connection with a site visit late 2020 or early 2021. “I am incredibly proud of the quality development towards accreditation that we have achieved together over the last few years,” says Martin Löfgren, Head of Department at Karlstad Business School.
Ground breaking research co-authored by Avit Bhowmik published in the Proceedings of the National Academy of Sciences presents six interventions that can rapidly transform societies for climate action. Safely achieving the goals of the Paris Climate Agreement demands a worldwide radical transformation of societies to help bend the emission curve immediately and halve global emissions no later than 2030. But, this is not an easy task!
Javid Taheri, a professor of Computer Science at Karlstad University, has received the “Award for Excellence” by the IEEE Technical Committee on Scalable Computing (TCSC). He was presented with this award for his contributions on cloud computing and use of artificial intelligence to optimise highly distributed cloud-based scalable systems. “I’m very happy to receive this award.
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.
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.
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.
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.
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.
During the holidays there is a lot of focus on food. It is the time of the year when we consume in abundance and throw away more food than ever- at the same time as we know that food waste has a negative impact on our climate and what we choose to eat and how we handle the food matters. So, what can we do to reduce the food waste?
A new study evaluated the association between early pregnancy exposure to eight PFAS compounds respectively and birth weight in 1,533 mother child pairs in the Swedish Environmental Longitudinal, Mother and child, Asthma and allergy (SELMA) study, specifically focusing on differences according to sex of the child. Researchers found significant associations between higher prenatal exposures for five different PFAS (PFOS, PFOA, PFNA, PFDA och PFUnDA) and lower birth weight,
At Karlstad University, there is research on polymer solar cells and how these can be made more stable and effective. Recently, a doctoral thesis was presented on how solar cell materials and functions are affected by contact with air and light. ”By now, almost everybody agrees that climate change is real,” says Vanja Blazinic, PhD in physics. ”We need to phase out fossil fuels and transit to renewable energy sources like sun, wind and water.
