Tidskriftsartikel (refereegranskat)abstract
- This paper presents two new approaches for finding the homogenized coefficients of multiscale elliptic PDEs. Standard approaches for computing the homogenized coefficients suffer from the so-called resonance error, originating from a mismatch between the true and the computational boundary conditions. Our new methods, based on solutions of parabolic and elliptic cell problems, result in an exponential decay of the resonance error.

Att lära sig nya språk genom att sjunga

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Artikel har två syften. Å ena sidan, vill jag påminna om fördelarna med att aktivt arbeta med så väl lyssnande, som av läsning och sjungande av sånger. Å Andra sidan, vill jag förespråka möjligheterna att lära sig ett språk utifrån skapande av sångtexter. I båda fallen, presenterar jag några exempel på sånger och några förslag till lingvistisk och musikalisk exploatering.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Purpose: To determine the phenolic and flavonoid contents of R. sativus rhizome ethanol extract and the hepatoprotective effect of the extract in rats.Methods: Folin–Ciocalteau and aluminum chloride colorimetric tests were used to determine the contents of phenols and flavonoids in the R. sativus extract. Male Sprague-Dawley rats induced with CCl4 to develop hepatotoxicity were treated orally with R. sativus extract for 4 weeks. The antioxidant and anti-inflammatory effects of the extract on the liver were determined by evaluating the concentration of oxidative analytes, serum liver enzymes, and lipids, and hepatic histopathology and cytochrome P450 2E1 expression.Results: R. sativus extract significantly (p < 0.05) reduced the hepatotoxic effect of CCl4 via its antioxidant activities and protection of liver tissues from oxidative damage.Conclusion: The hepatoprotective effects of R. sativus rhizome ethanol extract are attributed to its high phenolic and flavonoid contents.

When the climate apocalypse comes I’ll make it : 16 yr old Hampus' survival month in the forest
- 2020

Annan publikation (film/video) (populärvet., debatt m.m.)abstract
- When the climate apocalypse comes I’ll make it: 16 year old Hampus Andersson’s survival month living off the lands and waters in the forests of Norrbotten, Sweden. There is a lot of talk of crisis and apocalypse, due to war, to climate change. Young people worried about their future go on school strike and manifest, around the world. But, when the climate or any other crisis happens, how are these young (and adult) protesters prepared to fend for themselves? How long can you survive without electricity and water in the tap, with access to food in the supermarket? Thinking about all of this, 16 year old Hampus Andersson decided to try to live off the lands and waters for a full month, on his own. If there is such a crisis, would he make it on his own? From mid July to mid August 2019, the experiment went on. He made sure to learn from more experienced and older reindeer herders and others with experience from the forests. Hampus is not completely unaware on how to get access to food in the forest. His father is a Sámi reindeer herder, and his mother’s family are an agriculture family. But until this day he had never done such an experiment. How would he find food, water, shelter? What would be the hardest? Some things that he had never even thought about turned out to be harder than expected. During the stay Hampus documented his everyday life with photos and short films, and posted on his Facebook page and Instagram. This is a film made from those photos and videos, along with an interview by film maker Petri Storlöpare, Slowfilm AB. Hampus speaks of his experiences, thoughts and ideas on how to continue this experiment. Will he try the same in the Arctic winter, with temperatures down to minus 40 Celsius? The film project is supported by Dálkke: Indigenous Climate Change Studies, led by Dr. May-Britt Öhman, Centre for Multidisciplinary Studies on Racism, CEMFOR, Uppsala University.

Working the Aisles: A Life in Consumption
- 2014
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Working the Aisles takes the reader on tumultuous driving trips across the United States and France, on phone sex escapades in San Francisco, on banking battles in Sweden, and many other adventures – including, of course, on trips to supermarkets, where the author has had to ‘work the aisles’. Moving back and forth through time, like a novelist, indeed in something of a memoirist tour de force, the book develops the story of struggle, of poverty and depression, but also of gaiety and desire, of a will to live in spite of it all, and to keep working the aisles. It moves the reader through highs and lows, through episodes of ecstasy and thoughts about suicide, and tells how this particular Everyman ended up sane but sorry.

Characterizations of ground flashes from tropic to northern region
- 2014
-
Konstnärligt arbete (övrigt vetenskapligt/konstnärligt)abstract
- This thesis portrays new information concerning the cloud-to-ground (CG) lightning flashes or ground flashes produced by thunderclouds. It emphasizes the importance of characterizing lightning studies as the relationship between lightning mechanisms, and of incorporating the influence of geographical location, latitude and storm type. Sweden, Malaysia and USA were chosen as the main locations for field experiments in 2009 to 2011 to gather a significant number of negative and positive CG flashes. This work provided data on a total of 1792 CG lightning flashes (1685 negative and 107 positive ones) from a total of 53 thunderstorms by monitoring both the slow and the fast electric field and the narrowband radiation field at 3 and 30 MHz signals simultaneously. This thesis is comprised of: (i) the relationship of the Low Positive Charge Region (LPCR) and Preliminary Breakdown Pulse (PBP) trains to the occurrence of negative CG, (ii) slow field changes generated by preliminary breakdown processes in positive and negative ground flashes, and (iii) the occurrence of positive and negative ground flashes. It was revealed that the PBP train appeared have a higher strength in the in Sweden. The strength of the PBP train was caused by the LPCR; in contrast, weak PBP trains were characteristic in tropical countries constituting insignificant LPCR and needing little energy to break the “blocking” agent to allow the flash to propagate downward to the ground. The second contribution concerns the characteristics of the PBP train mentioned; this includes novel information for Malaysia. Further, it is stated that there are some different characteristics in the PBP trains in Johor, Malaysia and Florida, USA. The studies of slow field changes generated by preliminary breakdown processes clarifies unclear features concerning the starting position of slow field changes generated by preliminary breakdown processes in positive and negative ground flashes. It was found that the slow field changes did not occur before the initial process of the commencement of preliminary breakdown. Single-station electric field measurements incorporating narrowband radiation field measurement and high resolution transient recording (12 bits) with an accuracy of several nanoseconds, allows one to distinguish between the intracloud activities and the preceding processes of ground flashes. The results for the interstroke intervals, amplitude distribution of subsequent return-stroke (SRS) and the number of strokes per flash in the tropics, subtropics and northern regions were similar. Finally, a significant number of positive return-stroke (RS) electric fields provided statistically significant information on the characteristics of these strokes.
