Unveiling and controlling the electronic structure of oxidized semiconductor surfaces: Crystalline oxidized InSb(100)(1 x 2)-O

The exothermic nature of oxidation causes nearly all semiconductor applications in various fields like electronics, medicine, photonics, and sensor technology to acquire an oxidized semiconductor surface part during the application manufacturing. The significance of understanding and controlling the atomic scale properties of oxidized semiconductor surfaces is expected to increase even further wit

NMD is essential for hematopoietic stem and progenitor cells and for eliminating by-products of programmed DNA rearrangements

Nonsense-mediated mRNA decay (NMD) is a post-transcriptional surveillance process that eliminates mRNAs containing premature termination codons (PTCs). NMD has been hypothesized to impact on several aspects of cellular function; however, its importance in the context of a mammalian organism has not been addressed in detail. Here we use mouse genetics to demonstrate that hematopoietic-specific dele

Trade Facilitation and the EU-ACP Economic Partnership Agreements

This paper assesses the potential effects from trade facilitation in terms of increased trade flows both on average and specifically for the six regional groups of ACP countries negotiating Economic Partnership Agreements (EPAs) with the EU. Data from the World Bank’s Doing Business Database on the time required to export or import are used as indicators of cross-border transaction costs, and a gr

When the dust has settled: A final note on replication

Honing and Samuelsson have in a two papers (2014, 2015) criticized the Delmar and Shane (2003) paper on several grounds: The data are difficult to replicate; conflicting results with another paper using the same data and similar independent variable; the inability to fully rule out reversed causality because of tied events; and what is the choice of relevant dependent variable. I also commented on

Medkänslans makt och gränser. Nya linjer i känslornas historia

Den här artikeln belyser hur långa linjer kan bedrivas också kring känslor som omsorg och medkänsla. Därigenom önskar vi nyansera en traditionell berättelse om västerlandets historia, som i hög grad förklarat historien som en förnuftslig och handgriplig triumf över tidigare dominerande känslor som ångest och rädsla. En sådan förklaringsmodell baseras på teorier om känslor som inte längre har stöd

Classification, incidence and survival analyses of children with CNS tumours diagnosed in Sweden 1984-2005

Aim: Primary tumours in the central nervous system (CNS) are the second most common malignancy in childhood after leukaemia. Sweden has a high incidence and a high-survival rate in international comparative studies. This has raised the question about the type of tumours included in the Swedish Cancer registry. We therefore compared international data to the Swedish Childhood Cancer registry. Metho

Kejsarens nya kläder - implementering av evidensbaserad praktik i socialt arbete

Stat och kommun träffade 2010 en grundöverenskommelse om att införa en evidensbaserad praktik inom socialtjänsten. Sedan dess har överenskommelsen preciserats, en process som analyseras i denna artikel. Som vi kommer att visa återstår betydande oklarheter som det sociala arbetets aktörer behöver klargöra via förhandlingar. Detta är ett numera vanligt sätt att söka implementera politik och vi disku

Diamonds or development? A structural assessment of Botswana's forty years of success

Due to its four decades of high long-term economic growth and democratic system, Botswana has been depicted as an exceptional success story in a region full of economic and political failures. In this article,,a structural analysis is applied, and it is argued that Botswana's success should be understood as one of pre-modern growth without development. It is claimed that although the country may b

Multiscale Modeling of the Active Site of [Fe] Hydrogenase: The H-2 Binding Site in Open and Closed Protein Conformations

A series of QM/MM optimizations of the full protein of [Fe] hydrogenase were performed. The FeGP cofactor has been optimized in the water-bound resting state (1), with a side-on bound dihydrogen (2), or as a hydride intermediate (3). For inclusion of H4MPT in the closed structure, advanced multiscale modeling appears to be necessary, especially to obtain reliable distances between CH-H4MPT+ and th

Zinc bioavailability in rats fed a plant-based diet : A study of fermentation and zinc supplementation

Background: Zinc deficiency is a significant problem, in developing countries and in vegetarians, which can be caused by plant-based diets. Thus, dietary strategies, such as fermentation, to improve zinc bioavailability of diets should be investigated. Objective: To improve zinc bioavailability in a plant-based diet by the inclusion of fermented food. Design: Cassava tubers were fermented and made

Crosslinked plastic scintillators: A new detection system for radioactivity measurement in organic and aggressive media

The measurement of radioactive solutions containing organic or aggressive media may cause stability problems in liquid and plastic scintillation (PS) techniques. In the case of PS, this can be overcome by adding a crosslinker to the polymer structure. The objectives of this study are to synthesise a suitable crosslinked plastic scintillator (C-PS) for radioactivity determination in organic and agg

A helium gas scintillator active target for photoreaction measurements

A multi-cell He gas scintillator active target, designed for the measurement of photoreaction cross sections, is described. The target has four main chambers, giving an overall thickness of 0.103 g/cm(3) at an operating pressure of 2MPa. Scintillations are read out by photomultiplier tubes and the addition of small amounts of N-2 to the He, to shift the scintillation emission from UV to visible, i

Platelet activation and tissue factor release in hemolytic uremic syndrome

Hemolytic uremic syndrome (HUS) is a clinical syndrome characterized by microangiopathic hemolytic anemia, thrombocytopenia and acute renal failure. There are two subtypes: typical HUS associated with enterohemorrhagic E. coli (EHEC) and atypical HUS associated with uninhibited activation of the alternative pathway of complement. EHEC produce virulence factors such as lipopolysaccharide (LPS) and

Graphene coatings for chemotherapy: avoiding silver-mediated degradation

Chemotherapy treatment usually involves the delivery of fluorouracil (5-Fu) together with other drugs through central venous catheters. Catheters and their connectors are increasingly treated with silver or argentic alloys/compounds. Complications arising from broken catheters are common, leading to additional suffering for patients and increased medical costs. Here, we uncover a likely cause of s
