The Nile and the Grand Ethiopian Renaissance Dam: Is There a Meeting Point between Nationalism and Hydrosolidarity?
- 2015

In: Journal of Contemporary Water Research and Education. - 1936-704X. ; 155:1, s. 73-82

Journal article (peer-reviewed)abstract
- The soon-to-be completed Grand Ethiopian Renaissance Dam (GERD), which will be the largest hydroelectric power plant and among the largest reservoirs in Africa, has highlighted the need for expanding traditional integrated water resources management to better include the cultural, social, and political complexities of large water infrastructure in development projects. The GERD will store a maximum of 74 billion cubic meters of water corresponding to approximately the average annual outflow of the Nile from the Aswan high dam. Undoubtedly, the GERD will be vital for energy production and a key factor for food production, economic development, and poverty reduction in Ethiopia and the Nile Basin. However, the GERD is also a political statement that in one stroke has re-written the hydropolitical map of the Nile Basin. The GERD has become a symbol of Ethiopian nationalism or “renaissance” (hidase in Amharic). A contrasting concept to nationalism is hydrosolidarity. This concept has been put forward to better stress equitable use of water in international water management challenges that would lead to sustainable socioeconomic development. We use the opposing notions of nationalism and hydrosolidarity at three different scales, everyday politics, state policies, and interstate and global politics to analyse some aspects of the new hydropolitical map of the Nile Basin. We argue that nationalism and national interests are not necessarily negative standpoints but that there may instead be a meeting point where regional and national interests join with hydrosolidarity principles. We believe that this meeting point can maximize not only the common good, but also the good from a national interest point of view. For this, it is important not increase collaboration instead of being locked in to the historical narrative of nationalistic culture and historical discourse. This would benefit and improve future sustainability.

Effect of using conventional and controlled release fertiliser on nutrient runoff from various vegetated roof systems
- 2007
-
In: Ecological Engineering: the Journal of Ecotechnology. - : Elsevier BV. - 1872-6992. ; 29:3, s. 260-271

Journal article (peer-reviewed)abstract
- Extensive vegetated roofs are becoming popular as a way to improve the environmental quality of cities. As more vegetated roofs are installed, there is a need for knowledge pertaining to maintenance and impact vegetated roofs have on stormwater quality Our study investigated nutrient runoff, substrate nutrient storage and plant uptake following fertilisation of vegetation mats, shoot-established vegetation systems and unvegetated substrate using three levels of fertiliser applied as either controlled release fertiliser (CRF), or as a combination of CRF and conventional fertiliser. Conventional fertilisers caused high nutrient concentrations in the runoff water. Concentrations decreased during the duration of the experiment but at the end of the experiment they were still higher than after fertilisation with CRF. Conventional fertiliser also increased the total nutrient runoff. Vegetation system type influenced nutrient runoff and fertilisation of old vegetation mats reduced the risk for nutrient leaching compared to fertilisation of newly established surfaces. This can be attributed to temporary storage in substrate and increased uptake by vegetation. The temporary storage of nutrients following fertilisation indicated that there might be a risk for prolonged leaching. Thus, addition of conventional fertilisers or nutrient-rich material during production can reduce stormwater quality. (C) 2006 Elsevier B.V. All rights reserved.

Simulating river flow to the Baltic Sea from climate simulations over the past millennium
- 2009
-
In: Boreal Environment Research. - 1239-6095. ; 14:1, s. 173-182
-
Conference paper (peer-reviewed)abstract
- The aim of this study was to reconstruct river flow to the Baltic Sea using data from different periods during the past thousand years. A hydrological model coupled to simulations from climate models was used to estimate river flow. A "millennium" simulation of past climate from the ECHO-G coupled atmosphere-ocean global climate model provided climatological inputs. Results from this global model were downscaled with the RCA3 regional climate model over northern Europe. Temperature and precipitation from the downscaled simulation results were then used in the HBV hydrological model to simulate river flows to the Baltic Sea for the periods 1000-1199 and 1551-1929. These were compared with observations for the period 1921-2002. A general conclusion from this work is that although climate has varied during the past millennium, variability in annual river flow to the Baltic Sea does not appear more pronounced in recent years than during the previous millennium, or vice versa.

Sound psychometric properties of the Swedish version of the Spinal Cord Independence Measure Self-Report
- 2021
-
In: Journal of Rehabilitation Medicine. - : Medical Journals Sweden AB. - 1651-2081 .- 1650-1977. ; 53:5, s. 00197-00197

Journal article (peer-reviewed)abstract
- OBJECTIVE: To describe data completeness, targeting and reliability of the Swedish version of the Spinal Cord Independence Measure Self-Report (s-SCIM-SR). DESIGN: Translation and reliability study. SUBJECTS: Programme participants (n = 48) and peer mentors (n = 42) with spinal cord injury enrolled in the INTERnational Project for the Evaluation of "activE Rehabilitation" (inter-PEER). METHODS: The translation process was based on guidelines/recommendations, and involved expert competence, including consumers. The s-SCIM-SR was distributed online, once for programme participants and twice for peer mentors. RESULTS: Sixty-nine individuals (77%) obtained a total score. Most missing data were found in the items Respiration and Using the toilet. Cronbach's alpha for the full scale was 0.89, for Self-care 0.92, for Respiration and sphincter management 0.37 and for Mobility 0.86. The intraclass correlation coefficient was excellent for all subscales and the full scale. Measures of variability showed high sensitivity to changes and Bland Altman analyses revealed no systematic changes between evaluation points. CONCLUSION: These results support the data completeness, targeting and reliability of the Swedish version of the SCIM-SR. However, some problems were found in the subscale Respiration and sphincter management. The s-SCIM-SR can be considered psychometrically sound and suitable to assess physical independence among persons with spinal cord injury in Swedish community settings.

Correlation to FVIII : C in two thrombin generation tests: TGA-CAT and INNOVANCE ETP
- 2017
-
In: Mediterranean Journal of Hematology and Infectious Diseases. - : Institute of Hematology, Catholic University. - 2035-3006. ; 9:1
-
Journal article (peer-reviewed)abstract
- Introduction: Several thrombin-generation tests are available, but few have been directly compared. Our primary aim was to investigate the correlation of two thrombin generation tests, thrombin generation assay-calibrated automated thrombogram (TGA-CAT) and INNOVANCE ETP, to factor VIII levels (FVIII:C) in a group of patients with hemophilia A. The secondary aim was to investigate inter-laboratory variation for the TGA-CAT method. Methods: Blood samples were taken from 45 patients with mild, moderate and severe hemophilia A. The TGA-CAT method was performed at both centers while the INNOVANCE ETP was only performed at the Stockholm center. Correlation between parameters was evaluated using Spearman's rank correlation test. For determination of the TGA-CAT inter-laboratory variability, Bland-Altman plots were used. Results: The correlation for the INNOVANCE ETP and TGA-CAT methods with FVIII:C in persons with hemophilia (PWH) was r=0.701 and r=0.734 respectively. The correlation between the two methods was r=0.546. When dividing the study material into disease severity groups (mild, moderate and severe) based on FVIII levels, both methods fail to discriminate between them. The variability of the TGA-CAT results performed at the two centers was reduced after normalization; before normalization, 29% of values showed less than ±10% difference while after normalization the number increased to 41%. Conclusions: Both methods correlate in an equal manner to FVIII:C in PWH but show a poor correlation with each other. The level of agreement for the TGA-CAT method was poor though slightly improved after normalization of data. Further improvement of standardization of these methods is warranted.

Protein fractionation of broccoli (Brassica oleracea, var. Italica) and kale (Brassica oleracea, var. Sabellica) residual leaves — A pre-feasibility assessment and evaluation of fraction phenol and fibre content
- 2021

In: Food and Bioproducts Processing. - : Elsevier BV. - 0960-3085 .- 1744-3571. ; 130, s. 229-243

Journal article (peer-reviewed)abstract
- This pre-feasibility study evaluates the use of residual leafy green biomass from broccoli (Brassica oleracea, var. Italica) and kale (Brassica oleracea, var. Sabellica) as feedstock for protein fractionation and potential application of the fractions in food and feed products. The protein concentration, protein recovery potential and the content of phenols and dietary fibre in these biomass sources and fractions were investigated. Field produce and side-stream analysis showed that among broccoli and kale side-streams the potentially suitable leaves for protein fractionation constitute up to 16 and 1.9 t/ha (DM content), respectively. Fractionation demonstrated that between 34–42 and 25–34 kg total protein could be extracted per t DM of broccoli and kale residue leaves, respectively. The amount of protein was generally high in green protein fraction (GPF) and the white protein concentrate (WPC) of both crops, although significantly higher in broccoli compared to kale. The recovery of bound and free phenolic compounds was up to 18% in the GPF of both crops, while only 0.4% ended up in the WPC. The economic assessment showed that the feedstock and processing costs of producing GPF and WPC, as well as of the combined protein fraction (CPF) 1.9–6.0 and 1.3–3.9 times higher than expected revenues for broccoli and kale, respectively, indicating that the production of protein fractions is not economically feasible with the current production scheme. However, potentially higher revenues may be obtained if value-added products such as fractionated phenols and dietary fibre components are also included and investigated in future production schemes. The pathway investigated, that included a direct drying and milling of leaf biomass showed a low processing cost and thereby the most favourable economic alternative, with approx. 7–30% profit for kale, while for broccoli revenues covered only 44–47% of the costs due to the extra harvest cost of the broccoli leaves.
