Fireside corrosion of stainless and low alloyed steels in a waste-fired CFB boiler; The effect of adding sulphur to the fuel
- 2008
-
In: Materials Science Forum. ; 595-598, s. 289-297
-
Journal article (peer-reviewed)abstract
- Corrosion field tests have been carried out in the superheater region of a commercial waste-fired 75MW CFBC boiler using air cooled probes. Exposure time was 24 and 1000 hours. The effect of adding sulphur to the fuel on the corrosion of two high alloyed steels and a low alloyed steel was studied. The fuel consisted of 50% household waste and 50% industrial waste. The exposed samples were analyzed by ESEM/EDX and XRD. Metal loss was determined after 1000 hours. Both materials suffered significant corrosion in the absence of sulphur addition and the addition of sulphur to the fuel reduced corrosion significantly. The rapid corrosion of the high alloyed steel in the absence of sulphur addition is caused by the destruction of the chromium-containing protective oxide by formation of calcium chromate. Adding sulphur to the fuel inhibited chromate formation and increased the sulphate/chloride ratio in the deposit. Iron(II) chloride formed on the low alloyed steel regardless of whether sulphur was added or not.

Window dressing inequalities and constructing women farmers as problematic—gender in Rwanda’s agriculture policy
- 2022
-
In: Agriculture and Human Values. - : Springer Science and Business Media LLC. - 0889-048X .- 1572-8366. ; 39, s. 1245-1261
-
Journal article (peer-reviewed)abstract
- Rwanda is often depicted as a success story by policy makers when it comes to issues of gender. In this paper, we show how the problem of gendered inequality in agriculture nevertheless is both marginalized and instrumentalized in Rwanda’s agriculture policy. Our in-depth analysis of 12 national policies is informed by Bacchi’s What’s the problem represented to be? approach. It attests that gendered inequality is largely left unproblematized as well as reduced to a problem of women’s low agricultural productivity. The policy focuses on framing the symptoms and effects of gendered inequality and turns gender mainstreaming into an instrument for national economic growth. We argue that by insufficiently addressing the socio-political underlying causes of gendered inequality, Rwanda’s agriculture policy risks reproducing and exacerbating inequalities by reinforcing dominant gender relations and constructing women farmers as problematic and men as normative farmers. We call for the policy to approach gendered inequality in alternative ways. Drawing on perspectives in feminist political ecology, we discuss how such alternatives could allow policy to more profoundly challenge underlying structural constraints such as unequal gender relations of power, gender norms, and gender divisions of work. This would shift policy’s problematizing lens from economic growth to social justice, and from women’s shortcomings and disadvantages in agriculture to the practices and relations that perpetuate inequality. In the long term, this could lead to transformed gender norms and power relations, and a more just and equal future beyond what the dominant agricultural development discourse currently permits.

SYN-TES INTERDISCIPLINARY RESEARCH ON COLOUR AND LIGHT
- 2012
-
In: Proceedings for Interim Meeting of the International Colour Association (AIC); AIC 2012 “In Color We Live: Color and Environment”, 22 – 25 September 2012, Taipei, Taiwan. - : The International Colour Association. ; , s. 80-83, s. 80-83
-
Conference paper (peer-reviewed)abstract
- Colour and light have largely been considered as belonging to two different fields of knowledge, having disparate theoretical, terminological and methodological traditions. This creates a ground for misunderstandings and obstructs a fruitful interdisciplinary and interprofessional collaboration. A survey over international research literature from 2006 -2011 shows that there has been only little research on the spatial interaction between colour and light, but that the interest for this area has recently increased. The interdisciplinary Nordic research project SYN-TES: Human colour and light synthesis. Towards a coherent field of knowledge was carried out during 2010-11. Colour and light experts from Nordic universities and companies investigated different aspects of the spatial interaction between colour and light and its importance for human beings. This paper deals with the general learnings from the process. Specific results are presented in other papers at this conference.

Reception Policies, Practices and Responses : Sweden Country Report
- 2020
-
Reports (peer-reviewed)abstract
- This report explores reception policies, practices and humanitarian responses to the current refugee crisis in Sweden, focusing on the aftermath of 2015 unprecedented refugee migration, and also providing a brief historical perspective. Sweden has been known as one of the most generous countries in terms of welcoming refugees and providing an easy path to citizenship but its migration and reception policy has taken a ‘restrictive turn’ in recent years. The refugee crisis in 2015 has not only opened the window for ‘a major policy shift’ and ‘historical’ legislative changes to the Swedish migration and reception policy but also impacted the social, economic and political sphere instigating anti-immigrant sentiments.

In-situ studies of oxidation/reduction of copper in Cu-CHA SCR catalysts:comparison of fresh and SO2-poisoned catalysts
-
Journal article (other academic/artistic)abstract
- SO2-poisoning results in deactivation of Cu-CHA SCR under standard SCR conditions; however regeneration at 700 ◦C completely restores the SCR performance. To understand the nature of these effects, Cu-species in the fresh and poisoned catalystswere characterized by in-situ temperature-dependent time-resolved Cu K-edge X-ray absorption spectroscopy using the multivariate curve resolution alternating least squares (MCR-ALS) approach and continuous Cauchy wavelet transforms. The extracted chemically-meaningful reference spectra of Cu-species were analyzed by DFT-assisted XANES calculations. Cu-bisulfates werefound as the most energetically favorable poisoned Cu-species. The response of Cu-species to a reducing environment differs inthe fresh and SO2-poisoned catalysts. Differences in reducibility are related to the formation of quasi-linear Cu-complexes in the SO2-poisoned catalyst formed during heating in H2/He. Heating in H2/He leads to partial desulfurization of the poisoned catalyst. Cooling in H2/He after heating results in more facile formation of Cu-metal clusters in fresh catalyst than in SO2-poisoned.

The effect of high temperatures on seed germination of one native and two introduced conifers in Patagonia
- 2010
-
In: Nordic Journal of Botany. - Chichester : Wiley-Blackwell. - 0107-055X .- 1756-1051. ; 28:2, s. 231-239
-
Journal article (peer-reviewed)abstract
- We examined the effect of thermal shock on the germination of seeds of three conifers, two introduced (Pseudotsuga menziesii and Pinus ponderosa), and one native to Patagonia (Araucaria araucana). Previous research has suggested increased susceptibility to invasions in burnt areas, and therefore, the effect of simulated fire (heat) on seed germination in these native and introduced species was compared. Seeds were heated to two different heat intensities (50°C and 100°C) for 1 or 5 min, which is within the temperature range reached in the upper soil layers during forest fires. Germination tests were then carried out in a growth chamber. The heat treatments had a negative effect on the germination of P. menziesii at temperatures of 100°C, and a negative effect on the germination of P. ponderosa at the temperature of 100°C and the exposure of 5 min. The heat treatments had no affect at all on A. araucana. The species with larger seeds (A. araucana) had higher survival rates after the thermal shocks. Also intraspecific differences in seed sizes possibly point at larger seeds surviving thermal shocks better than smaller seeds. In addition, thermal shock caused a delay in the onset of germination in the two introduced species, while it did not change the time for germination in A. araucana. © The Authors.
