Journal article (peer-reviewed)abstract
- This paper provides an industrial-scale technical assessment of absorption of CO2 in water to react into bicarbonate (HCO3−), with the goal of storing HCO3− in the oceans as a carbon sequestration technology. A potential advantage of the process is that it will not require a CO2 transport and storage infrastructure that will be expensive for small-scale and remote emission sources. Process simulations are utilized to estimate absorber column length and for mass flow estimations of water and base required for a target capture rate of 90%. The results indicate that the process is technically feasible under specific conditions, with pH regulation being highly important, although the demand for base represents a limiting factor. Yet, a potential niche for the process is CO2 capture at smaller plants emitting small amounts of CO2.

Conference paper (peer-reviewed)abstract
- This work evaluates the fixed and running costs together with the CO2 avoidance cost of an O2/CO2 combustion process. The work is based on a comprehensive process study applied to commercial process data from an 865 MWe lignite fired reference power plant and large scale air separation units (ASU), in combination, with a detailed design study of the flue gas treatment and CO2 compression train (FGTCC) [1]. All costs for the process layout proposed in [1] are gathered from industry. Although an existing reference power plant forms the basis of the work, the study is directed towards a new state-of-the-art lignite-fired O2/CO2 power plant.

Living with life-saving technology : long-term follow-up of recipients with implantable cardioverter defibrillator
- 2010
-
Conference paper (peer-reviewed)abstract
- The evidence that treatment of life-threatening arrhythmia (LTA) with an Implantable Cardioverter Defibrillator (ICD) can prolong life is convincing. Living with a lifelong heart disease will gradually influence the everyday life and encompasses some or all aspects of life. In order to influence health outcomes, the impact of the ICD must be considered in a broader context including not only the physical, but also the psychological and social functioning of the individual.The general aim of this thesis was to describe everyday life in recipients living with an ICD in a longterm perspective. The aim in Paper I was to describe changes in the life situation of recipients’ with an ICD over a period of 1 year. The aim in Paper II was to describe quality of life (QOL) and uncertainty in recipients who have an ICD and to predict QOL at long-term follow-up. Fifty-six recipients participated (I) and 35 of these recipients, who had survived at least five years, were further included (II). The Quality of Life Index-Cardiac version (I, II), Mishel Uncertainty in Illness Scale-Community version (I, II), Patient ICD Questionnaire (I) and multiple regression analysis (II) were used. Higher scores indicate higher QOL and uncertainty. The questionnaires were completed before implantation, three and twelve months after implantation (I) and also five years after implantation i.e. long-term follow up (II). At the long-term follow up, the average ICD recipient had lived with an ICD for six years and nine months (6.9 years). The results showed the overall QOL and QOL in the health/functioning domain were unchanged over time. QOL in the socio-economic (p= .002) and psychological/spiritual domains (p= .012) decreased in the first year. From baseline to long-term follow up, the QOL in the family domain (p= .011) and overall uncertainty (p= .002) decreased. Uncertainty related to the information decreased at year 1 in relation to baseline (p= .001).The aim in Paper III was to illuminate the main concern of recipients living with an ICD and how they handle this in their daily life. Sixteen recipients who had lived with an ICD between six to twenty-four months were interviewed. Data was collected and analysed in a simultaneous process according to guidelines for classical grounded theory. In the analysis, a substantive theory was generated explaining the main concern of ICD recipients and how they handle this in their daily life. The core category, labelled “Striving to resume command”, illuminates the main concern of ICD recipients. To manage this main concern, the recipients used the following strategies: Economizing resources, Distracting oneself, Submitting to one’s fate and Re-evaluating life.The aim in Paper IV was to explore relationships between OQL, coping strategies, anxiety, depression and perceived control in recipients living with an ICD and to compare those having received an ICD less or more than one year ago and those with a primary or secondary preventive indication. A cross-sectional, correlational, multicenter design was used, and 147 recipients who had lived with an ICD between six to twenty-four months completed Quality of Life Index-Cardiac version, Jalowiec Coping Scale, Hospital Anxiety and Depression Scale and Control Attitude Scale. The results showed that anxiety, depression and perceived control were predictors of QOL. Anxiety was also a predictor of coping with optimistic coping being the most used coping strategy. There was no relationship between QOL and coping. No differences were found in QOL, coping, anxiety, depression and perceived control between recipients implanted either on a primary or secondary preventive indication or having the device less or more than one year.In this thesis, it was concluded that the ICD recipients strived to resume command over their life (III) and the more control the recipients perceived the more satisfied they were with their QOL (IV) and the more symptoms of anxiety, depression and uncertainty they experienced the less satisfied they were with their QOL (II, IV). Coping strategies were used more frequently by ICD recipient perceiving more anxiety (IV). QOL was fairly good 6,9 years after implantation and ICD recipients felt less uncertain once they had passed the first year of their illness.

Arbetarrörelsen, Folkets Hus och offentligheten i Bromölla 1905-1960
- 2009

Doctoral thesis (other academic/artistic)abstract
- The purpose of this dissertation is to analyze the People’s House in Bromölla as an arena for a plebeian public sphere. More specific, the analysis revolves around how the labour movement created a plebeian public sphere, the construction of the very arena and the activities there, including study circles, labour library, theatre plays, film showings, dance evenings and other amusements as parts of adult education among the working class people. It also comprises examinations of the labour movement’s acting in the local political arena, the labour movement’s connections with the local bourgeoisie on matters concerning politics and the People’s House. The main theoretical perspective is based on Jürgen Habermas’ theory of bourgeois public sphere, reformulated to a plebeian public sphere. The adult education in study circles mainly focused on subjects related to the work in the local politics and in the trade union, i.e. for the activities in the public sphere. These parts of the adult education were primarily a matter for the male part of the labour movement. This mirrors the situation in politics and in the trade union, where foremost men were engaged. Beside the trade union and political studies, subjects like Swedish, English, Esperanto, mathematics and literature were common. From time to time socialism and Marxism were studied. The women mainly studied humanistic subjects with individual development and hold thus the vision of the education ideologists within the labour movement. In the 1940’s the study circles decreased, and finally, in the end of the 1950’s almost ceased. Despite this the education did not cease, but were replaced by music, singing, dancing and machine sewing courses arranged by commercial companies and aesthetic associations. The People’s House was from the beginning open even for associations outside the labour movement. In the 1940’s and, in particularly, the 1950’s the People’s House became an assembly hall for a huge range of associations. Among the tenants were Free Church parishes, athletic associations, hobby associations, temperance societies, political parties from left to right, trade unions, authorities, companies, and the municipal of Bromölla. People’s house was also a place for wedding and birthday celebrations and other private parties. Among the more frequent tenants were Free Churches and music, singing and athletic associations, beside Bromölla municipal, which were a permanent tenant, for instance for the municipal library. The amount of associations from outside the labour movement among the tenants exceeded for some years in the end of 1950’s the labour movement’s meetings. This cross class policy was a conscious strategy by the People’s House association, in order to be a cultural institution for all inhabitants in Bromölla. The municipal council of Bromölla was even a part of this policy when subsidizing the People’s House association. It was in accordance with the cross class and consensus policy which the social democratic movement by this time was an exponent of. The People’s House in Bromölla was thus an arena not only for the labour movement, but also for the entire society.
