Monsterkroppar : Transformation, transmedialitet och makeoverkultur
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This study offers insights into the motif of monstrous corporality in a transmedia environment, through the vampire and zombie characters. Different narratives of corporeal transformation surround us constantly. On one hand, discourses of self-improvement in late modernity (Giddens 1991/2008) and ‘makeover culture’ (Johansson, 2006; 2012; Miller, 2008; Weber, 2009) demand a ‘creation of self’ through change and development, often in relation to physical appearance and bodily traits. On the other hand, numerous narratives of monstrosity and bodily change through destruction are also evident. This study takes on this double focus on corporality, against the backdrop of a late modern mediascape that has enabled people to imagine lives and possibilities different from their own through electronic mediation (Appadurai, 1996). As narratives now move between media platforms, new dimensions are brought to the imaginary, as different platforms interact differently with audiences.The aim of the study is to examine monstrous corporality in popular culture both in relation to media texts and audience practices through analyzes of representation, consumption and performance. The study examines medial and corporeal transformation through: concrete bodily change (the monstrous body), shifts between media platforms (transmedia) as well as the transmission of affect between media material and viewer (embodied spectatorship). These dimensions are explored in four empirical chapters, which examine two television series (True Blood and The Walking Dead) through textual analyses, the promotion of these series, audience participation (in online fora) and also participatory practices (Live action role play and zombie walks) through focus group interviews.The results indicate that the theme of monstrous corporeal change in TB and TWD reflects corporeal change in late modernity in several ways. Both transformations are focused on ‘before’ and ‘after’ and change of the monstrous body is connected to particular traits or parts of the body, which are also prominent in makeover culture narratives, such as skin, teeth and weight (appetite). The televisual narrative offers representations of bodily interiors and bodily harm that affect the viewers in a physical way, through an embodied spectatorship. The analyses of transmedia environments connected to the series indicate that the promotion of the programs use dimensions that emphasize the corporeal address, by bridging the gap between diegetic and actual reality. This is done through media environments (posters, websites and the like), and by introducing diegetic elements as actual, tangible objects in the actual reality of potential viewers. The analyses of posts on televisionwithoutpity.com show that participants use forum discussions as strategies to prolong and widen the media experience, and share it with others. Interviews with larpers and participants in zombie walks indicate that practices that stage the monstrous, also function as deepened embodied narrative experiences. Performances such as larps and zombie walks are interpreted as both conscious acts, and as strategies to handle unconscious performative (Butler, 1991/2006) dimensions of late modernity. Taken together, the zombie and vampire embody the pressures, risks and paradoxes connected to late modern makeover culture, and the mediated form they are presented through, tie them closer to those who engage in narratives about them.

- The presence of man-made gamma emitting radionuclides in the region within 32 km radius of the Ignalina NPP/Lithuania has been investigated during the period 2001-2004, prior to the closure of the first 4 the two operating RBMK 1500-type reactors. Gamma spectrometric measurements of various terrestrial and aquatic plants as well as of soil samples showed moderate environmental contamination with the fission product Cs-137 and with the neutron activation products Co-60 and Mn-54. Traces of the activation products Zn-65 and Ag-110m were found in the nearest vicinity of the NPP. Activity concentrations were inhomogeneously distributed in the area of interest. Moss and algae samples showed the highest uptake of radionuclides. In addition to the gamma spectrometric measurements, the levels of C-14 were determined in the same bio-indicator samples using accelerator mass spectrometry. (c) 2006 Elsevier Ltd.

Extending the scope of dispersive liquid–liquid microextraction for trace analysis of 3-methyl-1,2,3-butanetricarboxylic acid in atmospheric aerosols leading to the discovery of iron(III) complexes

- 3-Methyl-1,2,3-butanetricarboxylic acid (MBTCA) is a secondary organic aerosol and can be used as a unique emission marker of biogenic emissions of monoterpenes. Seasonal variations and differences in vegetation cover around the world may lead to low atmospheric MBTCA concentrations, in many cases too low to be measured. Hence, an important tool to quantify the contribution of terrestrial vegetation to the loading of secondary organic aerosol may be compromised. To meet this challenge, a dispersive liquid–liquid microextraction (DLLME) method, known for the extraction of hydrophobic compounds, was extended to the extraction of polar organic compounds like MBTCA without compromising the efficiency of the method. The extraction solvent was fine-tuned using tri-n-octyl phosphine oxide as additive. A multivariate experimental design was applied for deeper understanding of significant variables and interactions between them. The optimum extraction conditions included 1-octanol with 15% tri-n-octyl phosphine oxide (w/w) as extraction solvent, methanol as dispersive solvent, 25% NaCl dissolved in 5 mL sample (w/w) acidified to pH 2 using HNO 3 , and extraction time of 15 min. A limit of detection of 0.12 pg/m 3 in air was achieved. Furthermore, unique complexation behavior of MBTCA with iron(III) was found when analyzed with ultra-high-performance liquid chromatography coupled with electrospray ionization–quadrupole time-of-flight mass spectrometry (UHPLC–ESI–QToF). A comprehensive overview of this complexation behavior of MBTCA was examined with systematically designed experiments. This newly discovered behavior of MBTCA will be of interest for further research on organometallic photooxidation chemistry of atmospheric aerosols. [Figure not available: see fulltext.].

Towards the isolation and estimation of elemental carbon in atmospheric aerosols using supercritical fluid extraction and thermo-optical analysis
- 2017

- Air-starved combustion of biomass and fossil fuels releases aerosols, including airborne carbonaceous particles, causing negative climatic and health effects. Radiocarbon analysis of the elemental carbon (EC) fraction can help apportion sources of its emission, which is greatly constrained by the challenges in isolation of EC from organic compounds in atmospheric aerosols. The isolation of EC using thermo-optical analysis is however biased by the presence of interfering compounds that undergo pyrolysis during the analysis. EC is considered insoluble in all acidic, basic, and organic solvents. Based on the property of insolubility, a sample preparation method using supercritical CO2 and methanol as co-solvent was developed to remove interfering organic compounds. The efficiency of the method was studied by varying the density of supercritical carbon dioxide by means of temperature and pressure and by varying the methanol content. Supercritical CO2 with 10% methanol by volume at a temperature of 60 °C, a pressure of 350 bar and 20 min static mode extraction were found to be the most suitable conditions for the removal of 59 ± 3% organic carbon, including compounds responsible for pyrolysis with 78 ± 16% EC recovery. The results indicate that the method has potential for the estimation and isolation of EC from OC for subsequent analysis methods and source apportionment studies.

Tidskriftsartikel (refereegranskat)abstract
- The FLUKA code was applied to a simplified model of the tungsten target of the European Spallation Source (ESS) and shown to be suitable for modelling the radionuclide inventory of the ESS target. Two groups of radionuclides were selected based on dose factors and total predicted activities, one immediately after 5 years (designed lifetime of the target) of operation, and the other 10 years after shutdown. The predicted radionuclide production was higher than estimated by other authors for most of the radionuclides considered. The calculated 3H activity was close to the highest values obtained with other spallation models. Particular attention was paid to the evaluation of the production of one of the most toxic radionuclides, 148Gd. Differences in the predicted activities of 148Gd were mainly attributed to differences in the spallation and nuclear evaporation models used.
