Desiccants for retrospective dosimetry using optically stimulated luminescence (OSL)

Optically stimulated luminescence (OSL) was used to test different kinds of desiccants for their potential use in retrospective dosimetry. Desiccants are used for the purpose of absorbing liquids and can be found in a number of items which may be found in the immediate environment of a person, including hand bags, drug packages, and the vehicles of rescue service teams. Any material exhibiting OSL

Required ozone doses for removing pharmaceuticals from wastewater effluents

The aim of the this study was to investigate the ozone dosage required to remove active pharmaceutical ingredients (APIs) from biologically treated wastewater of varying quality, originated from different raw wastewater and wastewater treatment processes. Secondary effluents from six Swedish wastewater treatment plants (WWTP) were spiked with 42 APIs (nominal concentration 1 mu g/L) and treated wi

Social interaction among people with psychiatric disabilities - Does attending a day centre matter?

Background:Engaging in social interaction has, for people with psychiatric disabilities, been shown to enhance well-being and the experience of meaning and to generally prevent the worsening of mental illness.Aim:The aim of the study was to investigate how day centre attendees differed from non-attendees regarding different aspects of social interaction and to investigate how occupational factors,

Management of bleeding in acquired hemophilia A: results from the European Acquired Haemophilia (EACH2) Registry

Acquired hemophilia A is a rare bleeding disorder caused by autoantibodies to coagulation FVIII. Bleeding episodes at presentation are spontaneous and severe in most cases. Optimal hemostatic therapy is controversial, and available data are from observational and retrospective studies only. The EACH2 registry, a multicenter, pan-European, Web-based database, reports current patient management. The

Risk of Complications with Energy-Based Surgical Devices in Thyroid Surgery: A National Multicenter Register Study.

Energy-based surgical devices (EBD) combining cutting and coagulation are increasingly used in thyroid surgery. However, there is a lack of information about potential benefits and risk of complications outside controlled trials. The aims of this national multicenter register study were to describe the use of EDB, their potential effect on complication rates, and on operation time.

Determining Short Chain Fatty Acids in Sewage Sludge Hydrolysate: A Comparison of Three Analytical Methods and Investigation of Sample Storage Effects

In anaerobic digestion (AD), the production of short-chain fatty acids (SCFAs) can be beneficial or harmful to the overall process, depending on the concentration of accumulated acids. Therefore, the accurate determination of the SCFA concentration in both fresh and stored sludge hydrolysates is important. To select a suitable method for monitoring SCFAs during the AD of sewage sludge, the accurac

Semantic Holism and Language Learning

Holistic theories of meaning have, at least since Dummett’s Frege: The Philosophy of language, been assumed to be problematic from the perspective of the incremental nature of natural language learning. In this essay I argue that the general relationship between holism and language learning is in fact the opposite of that claimed by Dummett. It is only given a particular form of language learning,

Forage collection, substrate preparation and diet composition in fungus-growing ants

1. Variation and control of nutritional input is an important selective force in the evolution of mutualistic interactions and may significantly affect coevolutionary modifications in partner species. 2. The attine fungus-growing ants are a tribe of more than 230 described species (12 genera) that use a variety of different substrates to manure the symbiotic fungus they cultivate inside the nest.

Measurement of the inclusive isolated prompt photons cross section in pp collisions at root s=7 TeV with the ATLAS detector using 4.6 fb(-1)

A measurement of the cross section for the production of isolated prompt photons in pp collisions at a center-of-mass energy root s = 7 TeV is presented. The results are based on an integrated luminosity of 4.6 fb(-1) collected with the ATLAS detector at the LHC. The cross section is measured as a function of photon pseudorapidity eta(gamma) and transverse energy E-T(gamma) in the kinematic range

Apolipoprotein B, the villain in the drama?

Low-density lipoprotein (LDL) is the major atherogenic lipoprotein and the primary target of lipid-lowering therapy for treating ischemic cardiovascular disease. Apolipoprotein B (apoB), an important structural component of LDL, plays a key role in cholesterol transport and removal in vascular wall. On the other hand, under pathological process, apoB interacts with the arterial wall to initiate th

Tourist Place-Making in Practice

Tourist attractions emerge in stakeholder negotiation processes, where a critical issue is how different notions of meaning and value are argued and expressed. This article investigates this process of meaning production in practice through four examples of tourist attraction developments in Southern Sweden. Instances where tourist attractiveness is defined by stakeholders are analyzed by showing

Construction and Characterization of Kilobasepair Densely Labeled Peptide-DNA

Directed assembly of biocompatible materials benefits from modular building blocks in which structural organization is independent of introduced functional modifications. For soft materials, such modifications have been limited. Here, long DNA is successfully functionalized with dense decoration by peptides. Following introduction of alkyne-modified nucleotides into kilobasepair DNA, measurements

The influence of stochastic and selective forces in the population divergence of female colour polymorphism in damselflies of the genus Ischnura

Disentangling the relative importance and potential interactions of selection and genetic drift in driving phenotypic divergence of species is a classical research topic in population genetics and evolutionary biology. Here, we evaluate the role of stochastic and selective forces on population divergence of a colour polymorphism in seven damselfly species of the genus Ischnura, with a particular f

Maintenance treatment with azacytidine for patients with high-risk myelodysplastic syndromes (MDS) or acute myeloid leukaemia following MDS in complete remission after induction chemotherapy

P>This prospective Phase II study is the first to assess the feasibility and efficacy of maintenance 5-azacytidine for older patients with high-risk myelodysplastic syndrome (MDS), chronic myelomonocytic leukaemia and MDS-acute myeloid leukaemia syndromes in complete remission (CR) after induction chemotherapy. Sixty patients were enrolled and treated by standard induction chemotherapy. Patients t

The Political Ecology of Land Degradation

Land degradation, as a threat to smallholders in the tropics, attracts less attention than other global challenges. In addition, gaps between scientific understandings of land degradation and international policy regimes are problematic. We identify the three most significant debates including their different policy implications: desertification in the Sahel, nutrient depletion in Africa, and rura

Pathophysiology of typical hemolytic uremic syndrome.

The typical form of hemolytic uremic syndrome (HUS) is associated with enterohemorrhagic ESCHERICHIA COLI (EHEC) infection. The disease process is initiated and perpetuated by interactions between the pathogen or its virulence factors and host cells, as well as the host response. During EHEC-associated HUS, alterations occurring at the intestinal mucosal barrier and in the circulation, as well as

The effects of experience on the development of sexual behaviour of males and females of the banded demoiselle (Calopteryx splendens).

Mate preferences can vary in the direction of the preference, as well as the strength of the preference, and both direction and strength of preference are known to be plastic in many species. Preferences might have a learned component, and current and past social context may influence an individual's choosiness. In the damselfly species Calopteryx splendens, females increase the strength of their

Dynamics of femoral bone remodelling in well fixed total hip arthroplasty. A 20-year follow-up of 20 hips.

The aim of our study was to investigate the dynamics of cortical thinning around well fixed cemented Muller straight stems without osteolysis at different time periods during long term follow-up. We investigated patients operated on for osteoarthritis with a cemented Muller straight stem, all with more than 15 years follow-up and no radiological signs of osteolysis. Cortical thinning in 20 THA hip
