Nuclear superdeformation is studied theoretically using both simple models and more realistic numerical calculations. From the simple models general rules are formulated about the shell structure of the nucleus at large deformation, its affinity for reflection asymmetric or necked-in distortions and its response to rotation. The numerical calculations are based on realistic single-particle schemes

Collective properties at low and high spin for nuclei with Z ≥ 64 and N ≥ 82 are calculated on the basis o f deformed single-particle potentials. The calculations are confronted with the available experimental data like low-lying octupole bands, rotational bands of transitional nuclei with N ≥ 90 and evidence for collectivity in high-spin single-particle spectra. In the latter collective triaxiali

The Nilsson-Strutinsky approach to the description of yrast properties at very high spins is reviewed. Some recent calculations are presented and discussed with regard to the available experimental data. A nice agreement in the Te-region is pointed out. The aim is however more to describe physical trends than to make detailed predictions for specific nuclei. The general variation of the shell effe

Potential-energy surfaces at high spin are calculated for nuclei in the superheavy region by use of the cranked Nilsson hamiltonian. It is found, that the maximum fission barrier is shifted from the doubly magic 298114 to nuclei with fewer protons and more neutrons, as the spin increases. We also estimate, by use of simple models, the half-lives associated with alpha-decay, gamma-decay and fission

Calculations with the cranking-plus-Strutinsky formalism indicate that some part of the yrast line in almost all the nuclei of the A ∼ 40-80 region may be of non-collective type, corresponding to rotation around a symmetry axis. A numerical study of many such single-particle spectra shows that even at very high spins there is a non-negligible probability for the occurrence of isomers. This conclus

The cranked modified oscillator potential is used to study the nuclei 172-18072Hf at very high angular momenta. All these isotopes are found to "rotate around the prolate symmetry axis" for spin values I= 15-40 h {combining short stroke overlay}. In this region of spin we then look for prolate yrast traps. The pairing interaction with an approximative particle number projection as well as the hexa

The strategic role of communication practitioners has been discussedsince the 1970s. While it might not be surprising that managers andcoworkers view their roles as unclear, it is more surprising that commu-nication practitioners themselves also struggle with explaining theirstrategic roles and the value of their work. To elucidate the strategicwork of communication practitioners, we conducted a s

Civilsamhälleseliter kan definieras som individer med en ledande position i civilsamhällesorganisationer som ansamlar och förfogar över en oproportionerlig stor mängd resurser. På så vis har de bäst förutsättningar att utöva makt och inflytande i samhället

In Sweden, the occurrence of fictional texts in various media formats, including TV series, films, and computer games, most of which are in English, is constantly growing. In an increasingly digitalised society, there is a need for teaching that understands and meets the demand for aesthetic values as well as multimodality and creativity. Highlighting the aesthetic dimension of literary studies, t

This study explores re-creation processes, through transmedia storytelling, that are made visible in the Swedish TV-programme Helt lyriskt (2018), where music artists transmediate Swedish poems into songs. The aim is to analyse, through a close-reading method, two episodes of Helt lyriskt in order to discuss how processes of transmedia storytelling make literary analyses visible and accessible to

The present study focuses on consuming and producing stories using various forms of expression in the third-grade classroom. The aim of the study is to examine pupils’ and teachers’ experiences of working with a teaching unit that encourages the use of various text and media forms through literary productions, re-presentations, of Ronia, the Robber’s Daughter in order to gain increased insight int

Inom svensk forskning om läsundervisning har det framhållits att elever redan på mellanstadiet (åk 4-6) behöver utveckla litterär kompetens och få vägledning i hur de kan angripa och bearbeta en text för att utveckla fördjupad läsförståelse. Syftet med föreliggande artikel är att ge ett kunskapsbidrag beträffande hur undervisning som syftar till att utveckla förmågan att dra slutsatser om en skönlIn Swedish research on reading instruction, it has been emphasized that students already in middle school (grades 4-6) need to develop literary competence and receive guidance on how they can process a text in order to develop in-depth reading comprehension. The aim of the article is to contribute with knowledge regarding how teaching that aims to develop the ability to draw conclusions about a fi

This article presents a study of how meaning is created when participating in a fictional text universe, and thereby provides insight into literacy aspects of recreational use of fictional stories. The analysed material consists of transcriptions of pen-and-paper role-playing sessions. The results show that the role-players transform fragments of information from different languages, modalities an

Food is a major concern in popular culture and in literary studies at present and there are numerous novels, movies, and TV-shows that focus on food and its various functions – literary, cultural, and social. Food, which is a highly politicised subject, is one way in which cultural translation takes place as it is used to create an understanding of cultural transfer processes and their implication

Denna artikel redovisar en enkätstudie utförd bland svenska tonåringar i åldern 17-18 år. Studien syftar till att kartlägga deras användning av fiktion i olika medieformer i kontexterna skola och fritid. Studien har en kvantitativ ansats och fokuserar på aspekterna medieringstyp, kön och studieinriktning. Resultaten visar att även om deltagarna läser skönlitteratur, tillbringar de mycket mer tid mThis article reports on a questionnaire study conducted among Swedish teenagers aged 17-18. The study aims to map out their use of fictional texts through various media forms in the two contexts school and recreational time. The study, which has a quantitative approach, focuses on mediation, gender, and study orientation, when exploring the media habits of Swedish teenagers. The results show that

Cystatin C was identified as a marker of glomerular filtration rate (GFR) in 1979, and the parallel analysis of cystatin C and creatinine led to the identification of shrunken pore syndrome (SPS) ? a new kidney disorder ? in 2015. Since then, it has been shown that cystatin C in many aspects is superior to creatinine as a marker of GFR and cardiovascular risk. SPS, an entity within the selective g

The present study aims to explore in what ways teachers at upper secondary level work in a diverse classroom with particular focus on the students’ heterogeneous knowledge of the English language. This heterogeneity, the participants experience, is primarily caused by the discrepancy between those students who use English to a great extent outside the classroom through, for example, frequently pla

In a society where multimodal stories (movies, TV series, and computer games) have a big influence on young people, reports show that young people demonstrate a decrease in reading habits, reading comprehension, and reading abilities. This article analyses to what extent and in what way(s) various text and media forms are used in literary studies at upper secondary level in Sweden through intervie

The aim of this study is to analyse how a taxonomy-based course design can support students’ qualitative learning processes in online university courses. The paper presents a case study based on two online courses in comparative literature in Swedish and English. A document analysis has been applied to analyse the empirical material, which includes the syllabuses, study guides, and examination ass

This article is based on a questionnaire study of the media habits of Swedish youth aged 17–18. It examines the time they spend on using fictional texts through various media forms as well as in relation to mode (production/consumption), context (spare time/school), and gender (male/female). It further analyses these media habits and, using media ecology theory, discusses their effects on the lear
