- This work presents a comparison of the crystal packing of three eukaryotic membrane proteins: human aquaporin 1, human aquaporin 5 and a spinach plasma membrane aquaporin. All were purified from expression constructs both with and without affinity tags. With the exception of tagged aquaporin 1, all constructs yielded crystals. Two significant effects of the affinity tags were observed: crystals containing a tag typically diffracted to lower resolution than those from constructs encoding the protein sequence alone and constructs without a tag frequently produced crystals that suffered from merohedral twinning. Twinning is a challenging crystallographic problem that can seriously hinder solution of the structure. Thus, for integral membrane proteins, the addition of an affinity tag may help to disrupt the approximate symmetry of the protein and thereby reduce or avoid merohedral twinning.

Tidskriftsartikel (refereegranskat)abstract
- A large number of organic pollutants (OPs) emitted from vehicles and traffic-related activities exhibit environmental persistence and a tendency to bioaccumulate, and may have detrimental long-term effects on aquatic life. The aim of the study was to establish a list of significant sources of OPs occurring in road runoff, identify the OPs emitted from these sources, select a number of priority pollutants (PP), and estimate the quantity of PPs emitted in a road environment case study using substance flow analysis (SFA). The priority pollutants included in the SFA were selected from a list of approximately 1100 compounds found after comprehensive screening, including literature and database searches, expert judgments, the Ranking and Identification of Chemical Hazards method, and chemical analysis of sediments. The results showed the following priority order: polycyclic aromatic hydrocarbons (PAHs) > alkanes C20–C40 > alkylphenols > phthalates > aldehydes > phenolic antioxidants > bisphenol A > oxygenated-PAHs > naphtha C5–C12 > amides > amines. Among these, PAHs were chosen for a SFA, which was performed for a highway case study area in Gothenburg (Sweden). The SFA showed that the main sources of PAHs emitted in the area were vehicle exhaust gases, followed by tyre wear, motor lubricant oils, road surface wear, and brake linings. Only 2–6% of the total 5.8–29 kg annually emitted PAHs/ha ended up in the stormwater sewer system. The measured PAH loads were found in much smaller amounts than the calculated loads and the outflow to stormwater contained much more of the hazardous PAHs than the total loads emitted in the catchment area.

Global history or inter|nationalist discourse!? : Unsettling the 'comfort women' issue
- 2022
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Survivors of the ‘comfort’ system, the state-sponsored regime of military sexual exploitation and a core institution in the expansion of the empire of Japan from 1932 to 1945, continue to go unrecognised almost 80 years past 1945 and 30 years after the breakthrough by human rights activists in 1991. That such a brutal regime of sexual exploitation remains unrecognised by the state is remarkable and merits attention. In this thesis, I suggest that the ‘comfort women’ issue remains stuck in a deadlock that freezes it in the inter-state framing of a status quo. As a result the comfort women, the survivors and supposed protagonists, are rendered as mere tiles in a series of inter-state conflicts between the State of Japan and its neighbours in Northeast Asia as one of the fiercest battlegrounds in this region’s ‘history wars’. My purpose in the thesis is to offer possibilities to rethink the comfort women issue beyond this deadlock. To this end, I (1) identify the dynamics that sustain and reify the deadlock (Paper 1 and Paper 2) and (2) unsettle these dynamics (Paper 3 and Paper 4).

Representing the 'Comfort Women' : Omissions and Denials in Wartime Historiographies in Japan

Bokkapitel (refereegranskat)abstract
- This chapter scrutinizes the rationales for omissions and denials of the ‘comfort women’ in wartime historiographies in Japan. By demonstrating how the contracting argument reduces the comfort women’s subjugation to regular business transactions to privatize the responsibility for the ‘comfort women’ system and how the controversial Yasukuni Shrine and its adjacent Yūshūkan War Memorial Museum contextualize the war as a product of Japan’s pre-war history of humiliation to reframe the comfort women issue as a question about resisting international subjugation, the chapter suggests that the contracting argument’s denial of gender violence and the Yasukuni and the Yūshūkan’s omission of the comfort women establish the nation-state at the survivors’ expense and that human rights activism involuntarily ends up serving the populists’ ends no matter which actions they undertake.

Silencing speech and spoken silence in war memorialization in Japan

Bokkapitel (refereegranskat)abstract
- War memorialisation juxtaposes femininities against masculinities and silence against speech. In Tokyo, these relations are articulated in feminist herstories and revisionist historiographies. In Okinawa, the only 1931–1945 battleground in Japan, everyday silences instead connect representations of death to the martial everyday life around the military bases, where war is present as an everyday reality rather than a past event. This chapter complicates the affective connections of femininities to silence and masculinities to speech by scrutinising the juxtaposition of some against other war-dead at the Himeyuri Peace Museum (in Okinawa); the Women’s Active Museum on War and Peace; and the controversial Yasukuni Shrine with its adjacent Yūshūkan War Memorial Museum (in Tokyo). It concludes by suggesting that the spoken silences in the museum exhibitions unsettle the three narratives’ silencing work by illuminating the impossibility of telling one coherent story about life and death in this context.

Generation of nano- and micro-sized organic pollutant emulsions in simulated road runoff
- 2019

Tidskriftsartikel (refereegranskat)abstract
- A wide range of organic pollutants (OPs) are emitted from the road and traffic environment and transported with road runoff to receiving waters. To provide an understanding of the transport routes of OPs in the environment, an investigation was carried out with the aim to determine whether OPs are transported with nano- and microparticles in the form of emulsions. Tests were performed on simulated road runoff, using laboratory prepared mixtures of ultrapure water and specific polycyclic aromatic hydrocarbons (PAHs), alkylphenols (APs) and their ethoxylates (APEOs), phthalates, diesel oil (aliphatic hydrocarbons), with and without addition of humic acid (HA) and iron (Fe) colloids. The samples were analysed directly after mixing and after a few days of stabilisation for particle size distribution (PSD) and concentrations of particles in the size range 10 nm-100 mu m, and zeta potential> +/- 500 mV. Further, after long-term storage to achieve stabilisation, selected samples were investigated for the PSD and particle concentrations in the ranges 10 nm-2 mu m, to determine whether stable emulsions had formed. The following simulation mixtures, both mixed and stabilised, were identified as potential emulsions: diesel, APs and APEOs, diesel with APs and APEOS, phthalates, and a mixture of all OPs with and without colloids. Measurements with the Zetasizer and Nanosight instruments imply that the majority of particles in the samples were found in the nano-range of 30-660 nm respectively, and a smaller portion of particles < 28% also measured with Coulter Counter were found to be micro-sized. Higher concentrations of the smallest nanoparticles were found in the mixture of all OPs without colloids added, than in the OP mixture with colloids added. The results indicate that the addition of colloids favours the formation of larger micro-sized emulsions that may break down with time into nano-sized particles. In the mixed samples, the number of micro-sized particles decreased, while the number of nanoparticles increased; this process may also occur in road runoff transportation systems during heavy rain events. This is the first study to indicate that emulsions of OPs may be formed in road runoff, and that emulsions may act as carriers of OPs in urban stormwater.
