Collimated Gamma Transmission Micro-Densitometry (GTMD) is a novel technique proposed to investigate local density variations of nuclear fuel in PIE, with a high spatial resolution. In this work, the first experimental tests of a gamma micro-densitometer are presented and the performance is characterized. The experimental procedures are described, including the aligning process and the calibration methodology. The results demonstrated that for the calibration samples with a thickness above 5 mm, a local density was obtained with a maximum discrepancy of about 2% and a spatial resolution of about 280 µm. The setup was used for the first test on an irradiated ADOPTTM fuel pellet slice. From the measurement, an average bulk density of about 9.58 g/cm3 was calculated and local density features were observed, possibly related to rim effects or the presence of local cracks. The information acquired also presented valuable information for possible improvements in the setup’s performance.

TiO2-II is a high pressure form of titania with a density about 2% larger than that of rutile. In contrast to the common polymorphs anatase, brookite and rutile its electronic structure and optical properties are poorly characterized. Here we report on a comparative electron-energy-loss-spectroscopy (EELS) study for which high resolution valence-loss and core-loss EELS data were acquired from nanocrystalline (<75 nm sized) titania particles with an energy resolution of about 0.2 eV. Electronic structure features revealed from titanium L3,2 and oxygen K electron energy loss near-edge structures show a strong similarity of TiO2-II with both rutile and brookite, which is attributed to similarities in the connectivity of octahedral TiO6 units with neighboring ones. From combined valence-loss EELS and UV-VIS diffuse reflectance spectroscopy data the band gap of TiO2-II was determined to be indirect and with a magnitude of ∼3.18 eV, which is very similar to anatase (indirect, ∼3.2 eV), and distinctly different from rutile (direct, ∼3.05 eV) and brookite (direct, ∼3.45 eV).

Background: Evidence abounds on the independent roles of social class and smoking in relation to obstructive airway diseases, but data are sparse on the impact of their interaction. We evaluated whether and to what extent social class and smoking interact in relation to risk of respiratory diseases in adults. Methods: Data from the population-based studies, West Sweden Asthma Study (WSAS, n = 23,753) and Obstructive Lung Disease in Northern Sweden studies (OLIN, n = 6519), were used, constituting randomly selected adults aged 20–75 years. Bayesian network analysis was used to estimate the probability for the interaction between smoking and socioeconomic status in relation to respiratory outcomes. Results: Occupational and educational SES modified the association between smoking and the probability of allergic and non-allergic asthma. Former smokers who were at intermediate non manual employees and manual workers in service had higher probability of allergic asthma compared to professionals and executives. Furthermore, former smokers with primary education had higher probability of non-allergic asthma than those with secondary and tertiary education. Similarly, former smokers among professionals and executives had higher probability of non-allergic asthma than manual and home workers and primary educated. Likewise, allergic asthma due to former smoking was higher among highly educated compared to low educated. Conclusions: Beyond their independent roles, socioeconomic status and smoking interact in defining the risk of respiratory diseases. Clearer understanding of this interaction can help to identify population subgroups at most need of public health interventions.

In the wake of the enthusiasm for green energy, previously contested energy and mining projects can be framed as part of a green transition. When state authorities decide to forego the standard procedural protections and the processes and forums for deliberation and local influence, it contributes to constructing green sacrifice zones. This paper compares two Swedish energy policy processes. The first is occurred during World War II and the hydropower expansion of the 1940s and 1950s. The second takes place today when wind power is expanding to increase renewable energy production. In Sweden, policymaking seems to be back to square one in the green transition, leaving out both important knowledge of the past and contemporary voices of the ongoing and probable consequences. In certain issues, such as how the recognition of the Indigenous status of the Sámi actually affects the legislative process and how to address the Indigenous rights of the Sámi, policymaking is particularly slow to adapt. The green transition industry is already affecting the Sámi, as the construction of the Nordic welfare society has done during the last century, and still does. It deepens an ongoing colonial wave that started in the 1300s. By showing how the Swedish legislative process, historically as well as currently, has neglected to involve Sámi representatives, this study points to the importance and obligation of Swedish policymaking to engage Sámi representatives in an early phase to avoid further sacrifice zones in Sápmi.

This paper revisits the Swedish banking crisis (1919–1926) that materialized as post-war deflation replaced wartime inflation (1914–1918). Inspired by Fisher’s “debt deflation theory,” we employ survival analysis to “predict” which banks would fail, given certain ex-ante bank characteristics. Our tests support the theory; maturity structures mattered most in a regime of falling prices, with vulnerable shorter-term customer loans and bank liabilities representing the most consistent cause of bank distress in the crisis. Similarly, stronger growth in (1) leverage, (2) weaker collateral loans, and (3) foreign borrowing during the boom were all associated with bank failure.

A common, yet poorly evaluated, advice to remove contaminants from urban vegetables is to wash the produce before consumption. This study is based on 63 samples of chard, kale, lettuce and parsley that have grown near a heavily trafficked road in the third largest city in Sweden, with one portion of each sample being analysed without first being washed, and the other portion being subjected to common household washing. Concentrations of 71 elements were analysed by ICP-SFMS after a sample digestion that dissolves both the plant tissues and all potentially adhering particles. The results show that the washing effect, or the fraction removed upon washing, varies significantly between elements: from approximately 0 % for K to 68 % for the ∑REEs. Considering traditional metal contaminants, the efficiency decreased from Pb (on average 56 % lost) to Co (56 %) > Cr (55 %) > As (45 %) > Sb (35 %) > Ni (33 %) > Cu (13 %) > Zn (7 %) > Cd (7 %), and Ba (5 %). A clear negative correlation between the washing effect and the different elements' bioconcentration factors shows that the elements' accessibility for plant uptake is a key controlling factor for the degree to which they are removed upon washing. Based on the average washing efficiencies seen in this study, the average daily intake of Pb would increase by 130 % if vegetables are not washed prior to consumption. For the other contaminant metals this increase corresponds to 126 % (Co), 121 % (Cr), 82 % (As), 55 % (Sb), 50 % (Ni), 16 % (Cu), 8 % (Zn), 7 % (Cd) and 5 % (Ba). The advice to wash vegetables is therefore, for many elements, highly motivated for reducing exposure and health risks. For elements which are only slightly reduced when the vegetables are washed, however, advising should rather focus on reducing levels of contamination in the soil itself.

This paper discusses the role of housing for the structural transformation of an economy away from the agricultural to the manufacturing sector in a general equilibrium model. The model explains evidence from China (1978-2015). Due to the urban-rural wage gap there is domestic migration from the rural to the urban areas. The resulting increase in urban house prices can constitute an endogenous barrier to further urbanization. Despite massive growth the inequality of income is not on the decline. Increasing housing prices increase within-urban inequality and also lock in urban-rural wage differences. The calibrated model explains current and projects future development in China.

Abstract While emigration and population displacements have long been a feature of Iraqi history, this article argues that the 2003 Anglo-American intervention in Iraq and its legacy has contributed to the gradual disappearance of many non-Muslim Iraqi minorities from Iraq. Though the legacy of 2003 can be attributed to a confluence of domestic and geopolitical factors, it is argued here that the 2003 intervention set in motion a process of nation-destroying instead of nation-building, as Iraqi nationhood was divided along primordial lines. Caught between competing ethnic and sectarian nationalisms, Iraqi non-Muslim minorities became targets in the quest for territorial gain and political power heralding an unprecedented and steady level of emigration. This has changed the ethnic and religious demographic of Iraq, the identity of the Iraqi nation-state, as well as fragmented Iraq's multiple ethnic and religious nations both inside and outside the country. Indeed, the effects of nation-destroying have also been transported to the diaspora, strengthening communal identities, altering attachments and creating distance between Iraqi communities abroad. This has led to distanced transnational ethnic and religious Iraqi nations in diaspora who must now also contend with assimilation, a loss of culture and language in the absence of physical links to Iraq. The article offers the first comprehensive and scholarly treatment of the effects of emigration of Iraq's non-Muslim minorities on Iraqi nationhood within the new Iraqi nation-state. It therefore contributes conceptually and empirically to advancing our understanding of the role of nation-destroying and emigration in nationalizing processes, a neglected area in current migration and nationalism scholarship.

We present an in-situ and real-time investigation of the formation of YHO and GdHO thin films grown by reactive e(-)-beam evaporation. Mass changes were continuously monitored during deposition, oxidation, and illumination using a highly sensitive quartz crystal microbalance, while changes in chemical composition and depth profiles were investigated simultaneously by ion beam analysis. Results highlight the strong reactivity of freshly deposited YHx and GdHx films, even under ultra-high vacuum conditions. Oxidation starts at the surfaces of the films and the oxidation rate is strongly dependent on the O-2 pressure. The response of the system under ion beam irradiation and in-situ illumination is also presented and discussed. For the measured mass changes, a quantitative agreement better than 2% was observed between both techniques and demonstrates the consistency and sensitivity of this approach.

Exam scores are often the main criteria of students’ priorities in college admissions. Depending on the timing of preference submissions relative to the knowledge of scores, students have various degrees of information about their own priorities. I study three widely used timings under the Boston mechanism. The results suggest first, timing that is associated with less information about priorities yields higher expected utility ex-ante; Second, timing with full information about priorities generates full sorting on scores, whereas timing with less information reduces the tension of such sorting.
