- The expected increase in precipitation and temperature in Scandinavia, and especially short-time heavy precipitation, will increase the frequency of flooding. Urban areas are the most vulnerable, and specifically, the road infrastructure. The accumulation of large volumes of water and sediments on road-stream intersections gets severe consequences for the road drainage structures. This study integrates the spatial and temporal soil moisture properties into the research about flood prediction methods by a case study of two areas in Sweden, Vastra Gotaland and Varmland, which was affected by severe flooding in August 2014. Soil moisture data are derived from remote-sensing techniques, with a focus on the soil moisture-specific satellites ASCAT and SMOS. Furthermore, several physical catchments descriptors (PCDs) are analyzed and the result shows that larger slopes and drainage density, in general, mean a higher risk of flooding. The precipitation is the same; however, it can be concluded that more precipitation in most cases gives higher soil moisture values. The lack, or the dimensioning, of road drainage structures seems to have a large impact on the flood risk as more sediment and water can be accumulated at the road-stream intersection. The results show that the method implementing soil moisture satellite data is promising for improving the reliability of flooding.

- An attractive solution to mitigate tars and also to decompose lighter hydrocarbons in biomass gasification is secondary catalytic reforming, converting hydrocarbons to useful permanent gases. Albeit that it has been in use for a long time in fossil feedstock catalytic steam reforming, understanding of the catalytic processes is still limited. Naphthalene is typically present in the biomass gasification gas and to further understand the elementary steps of naphthalene transformation, we investigated the temperature dependent naphthalene adsorption, dehydrogenation and passivation on Ni(111). TPD (temperature-programmed desorption) and STM (scanning tunneling microscopy) in ultrahigh vacuum environment from 110 K up to 780 K, combined with DFT (density functional theory) were used in the study. Room temperature adsorption results in a flat naphthalene monolayer. DFT favors the dibridge[7] geometry but the potential energy surface is rather smooth and other adsorption geometries may coexist. DFT also reveals a pronounced dearomatization and charge transfer from the adsorbed molecule into the nickel surface. Dehydrogenation occurs in two steps, with two desorption peaks at approximately 450 and 600 K. The first step is due to partial dehydrogenation generating active hydrocarbon species that at higher temperatures migrates over the surface forming graphene. The graphene formation is accompanied by desorption of hydrogen in the high temperature TPD peak. The formation of graphene effectively passivates the surface both for hydrogen adsorption and naphthalene dissociation. In conclusion, the obtained results on the model naphthalene and Ni(111) system, provides insight into elementary steps of naphthalene adsorption, dehydrogenation, and carbon passivation, which may serve as a good starting point for rational design, development and optimization of the Ni catalyst surface, as well as process conditions, for the aromatic hydrocarbon reforming process.

Synthetic paper
- 2017
-
Patent (populärvet., debatt m.m.)abstract
- A synthetic paper is manufactured with a method comprising the steps of: a) providing at least two types of pho to-polymerizable monomers, b) exposing the volume to a three-dimensional light pattern to induce a polymerization reaction, and c) removing uncured monomer to create an open microstructure. The volume comprises at least one monomer comprising at least two thiol groups and at least one monomer comprising at least two carbon-carbon double bonds, where the ratio (r1) between the number of thiol groups and the number of carbon-carbon double bonds fulfils one of: 0.5≦r1≦0.9 and 1.1≦r1≦2. One advantage is that off stoichiometry creates an edge effect giving better defined boundaries between exposed and unexposed parts in the volume and giving a possibility to create thinner micro pillars. Another advantage is that it is easy to bind molecules to the surface to obtain desired surface properties.

Bakom bilderna : Biskopsporträtt i Strängnäs
- 2019. - 1
-
Bok (populärvet., debatt m.m.)abstract
- Sedan reformationstiden finns en serie porträtt av Strängnäs stifts biskopar. De flesta hänger i domkapitelshuset, ett par i biskopsgården och de är inte lätta att få se. Men i denna bok visas de alla, från Petrus Jonæ till Hans-Erik Nordin. Vilka var då dessa män bakom bilderna? Alla biskopar sedan reformationen ges i denna bok en presentation; deras bakgrund, inriktning och biskopsgärning skildras. I en övergripande artikel sätts denna porträttkonst också in i sitt sammanhang. Stav, biskopsmössa och kors är tre av biskoparnas insignier. Strängnäsbiskoparnas kåpor, stavar och biskopsringar liksom biskopsstolen i domkyrkan skildras i text och bild, allt från biskop Rogges medeltida kåpa till dagens enkla resekåpor. Bakom bilderna har utarbetats inom Strängnäs stifts herdaminneskommitté och är författad av professor Ingun Montgomery, teol. dr. Jarl Jergmar, teol. dr. Fredrik Santell, prosten Karin Karlberg, fil. dr. Margareta Nisser Dalman och docent Klas Hansson, som också varit bokens redaktör.

Democracy and the Church of Sweden : An unresolved dilemma

Tidskriftsartikel (refereegranskat)abstract
- The Church of Sweden was democratized in the 1930s when party politics was introduced into church elections. Since then, party politics have more and more been part of the governing style of the Church of Sweden. In 2000 the church was disestablished and a new election system was introduced with direct elections to the General Synod. The system of political parties remained. This article questions the democracy of the church using criteria for democratic structures. It also focuses on the role of the ordained ministry in the governance of the church, as the bishops have not been full members of the Synod since 1982. The conclusions are that the Church of Sweden is not fully democratic since participation in elections is at about 10% and the electorate has few chances to understand what the elections are about. The bishops’ weak formal position in the Synod is not in accordance with the teachings of the church on episcopacy. The conflict between democratic principles, inherited from the Swedish constitution, and church teaching on the ordained ministry and its role has not been fully resolved so far.

Kyrkomöte och partipolitik : Politisk påverkan på Svenska kyrkans kyrkomöte 1930–2018
- 2019. - 1
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Kyrkomöte och partipolitik – går det ihop? Ibland sägs att Svenska kyrkan är politiserad utan närmare precision. Handlar det om hur den styrs, om dess budskap eller om prästernas inställning? Skilda uppfattningar om Svenska kyrkan speglas också i motsättningar om kyrkomötet ska vara direktvalt eller bygga på val från församlingarna. Är kyrkomötet medlemmarnas organ eller församlingarnas? Den här undersökningen tar sikte på Svenska kyrkans kyrkomöte och tecknar bilden av hur kyrkomötet förändrats sedan 1930-talet och vilken roll de politiska partierna spelar i kyrkomötet, främst sedan relationerna med staten förändrades. Undersökningen avslutas med en genomgång av ett tiotal ärenden från tiden efter relationsförändringen med staten för att se om det finns politiska agendor bakom olika förslag. Undersökningen är en del i en större studie om förhållandet mellan politik och kyrka.
