- Objectives: Gastrointestinal graft-versus-host disease (GI-GVHD) is a potentially life-threatening complication after hematopoietic stem cell transplantation. Symptoms indicating GI-GVHD motivates endoscopy with biopsy sampling and histopathological confirmation. Optimal extent of endoscopy in children is, however, presently unknown. Therefore, we aimed to evaluate whether biopsies from the rectosigmoid area versus the rest of the colon/ileocolon with or without biopsies from simultaneous upper endoscopy, were equally reliable for detection of GI-GVHD and relevant differential diagnoses.Methods: Retrospective multicenter study based on histopathological re-evaluation of biopsies and hospital record data, collected from children with suspected GI-GVHD.Results: Forty-four children with 51 endoscopic occasions (81 procedures) were included. Thirty-nine of 51 (76.5%) were diagnosed as GI-GVHD, 14 (27.4%) received a differential diagnosis and 7 (13.7%) had normal histology findings. Comorbidity, that is, simultaneous detection of a differential diagnosis and GI-GVHD, was observed in 9 (23.1%) cases. Cytomegalovirus infection was the most frequent differential diagnosis, 6 of 7 were detected in biopsies from rectosigmoid and esophagogastroduodenal areas. Sensitivity for detection of GI-GVHD in biopsies collected from rectosigmoid-ileocolonic-, rectosigmoid-, or esophagogastroduodenal areas were 97.4%, 84.6%, 83.3%, respectively, and 97.4% when the latter 2 were merged. The difference, nondetected GI-GVHD in the rectosigmoid area versus detected elsewhere in the GI tract, was statistically significant (P = 0.03).Conclusions: Biopsies collected from the rectosigmoid area solely were not optimal for detection of pediatric GI-GVHD. When biopsy sampling from rectosigmoid and upper GI tract areas was combined, the sensitivity for GI-GVHD was, however, equally high as for ileocolonoscopy or full upper and lower endoscopy.

Development of an electro-chemical accelerated ageing method for leaching of calcium from cementitious materials

- To facilitate the long term durability predictions of nuclear waste repositories, acceleration methods enhancing calcium leaching process from cementitious materials are needed, even though mechanisms not necessarily comparable to those predominant in a natural leaching process may be developed. In the previously published acceleration methods the samples are very small, which limits further physical or mechanical tests. In this paper, a new acceleration method based on electro-chemical migration is presented. The method although not driven with the same kinetics as in natural leaching, was designed in such a way that unnecessarily destructive by-effects could be minimized while promoting a higher leaching rate for a sample size suitable for further testing the mechanical and physical properties. It is shown that approximately 1x10^6 C of electrical charge per paste specimen of size Ø50 x 75 mm (approximately 230 g) is required to leach out the total amount of Portlandite. The chemical and mineralogical properties of leached samples are characterized by various techniques. It is concluded that aged samples are comparable to those leached in a natural leaching process as both are characterized by a layered system comprising an unaltered core delineated by total dissolution of Portlandite followed by a progressive decalcification of the calcium silicate hydrate gel.

The EU’s Role in Fighting Global Imbalances
- 2015
-
Bok (refereegranskat)abstract
- The EU’s Role in Fighting Global Imbalances looks at the role of the European Union in addressing some of the greatest challenges of our time: poverty, protectionism, climate change, and human trafficking. Contributions from ten leading scholars in the fields of economics, law, and political science provide in-depth analyses of three key dimensions of EU foreign policy, namely: the internal challenges facing the EU, as its 28 member countries struggle to coordinate their actions; the external challenges facing the EU on the global arena, in areas where global imbalances are particularly pervasive, and where measures taken by the Union can have an important impact; and the EU´s performance on the global arena, in the eyes of other key actors. Based on a broad and interdisciplinary understanding of the concept of global imbalances, this book argues that these challenges follow from pervasive global imbalances, which at root are economic, political, and legal in character.

Performance of timing resistive plate chambers with relativistic neutrons from 300 to 1500 MeV

Tidskriftsartikel (refereegranskat)abstract
- A prototype composed of four resistive plate chamber layers has been exposed to quasi-monoenergetic neutrons produced from a deuteron beam of varying energy (300 to 1500 AMeV) in experiment S406 at GSI, Darmstad, Germany. Each layer, with an active area of about 2000 × 500 mm2, is made of modules containing the active gaps, all in multigap construction. Each gap is defined by 0.3 mm nylon mono-filaments positioned between 2.85 mm thick float glass electrodes. The modules are operated in avalanche mode with a non-flammable gas mixture composed of 90% C2H2F4 and 10% SF6. The signals are readout by a pick-up electrode formed by 15 copper strips (per layer), spaced at a pitch of 30 mm, connected at both sides to timing front end electronics. Measurements of the time of flight jitter of neutrons, in the mentioned energy range, point to a contribution of the resistive plate chamber in the order of 150 ps, independent of the neutron energy.

Bridging the Prosperity Gap in the EU : The Social Challenge Ahead
- 2018
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Bridging the Prosperity Gap in the EU addresses the great social challenge currently facing the European Union. Taking an interdisciplinary approach, the authors invaluably pinpoint both overarching problems and possibilities associated with the social dimension of European integration. Prominent researchers of economics, law and political science tackle this complex issue, providing new solutions within their respective fields of expertise. The chapters cover crucial policy challenges and analyse fundamental mechanisms that limit, or otherwise affect, the evolution of a European social dimension. These insights clarify the far-reaching measures that will be needed to gradually restore the balance between market integration and social protection across the European Union. Illustrating the importance of cohesion, this book is vital for those interested in comparative European studies, from backgrounds in public and social policy, law and economics.
