Study of a high spatial resolution B-10-based thermal neutron detector for application in neutron reflectometry: the Multi-Blade prototype

Although for large area detectors it is crucial to find an alternative to detect thermal neutrons because of the He-3 shortage, this is not the case for small area detectors. Neutron scattering science is still growing its instruments' power and the neutron flux a detector must tolerate is increasing. For small area detectors the main effort is to expand the detectors' performances. At Institut La

Cluster headache associated with acute maxillary sinusitis.

Cluster headache is a primary headache by definition not caused by any known underlying structural pathology. However, symptomatic cases have been described, for example tumours, particularly pituitary adenomas, malformations, and infections/inflammations. The evaluation of cluster headache is an issue unresolved.

Systemic sclerosis. Novel molecular and epidemiological features of disease.

Popular Abstract in Swedish Systemisk skleros (SSc) är en relativt ovanlig reumatologisk sjukdom som kan engagera många av kroppens organ. Sjukdomen kallas ibland också för sklerodermi. Typiskt för sjukdomen är att huden omvandlas till fibros och blir hård och stram över olika delar av kroppen. Typiskt för sjukdomen är också att drabbade patienter har försämrad funktion i sina blodkärl, framförallSystemic sclerosis (SSc) is a systemic rheumatic disease with significant mortality and morbidity. Different estimations of disease prevalence and incidence have been presented from various parts of the world. While lung involvement is a common cause of SSc-related death, a majority of SSc patients suffer from symptoms originating in the gastrointestinal (GI) tract. By combining data from a popu

GAD Autoantibody Affinity in Adult Patients With Latent Autoimmune Diabetes, the Study Participants of a GAD65 Vaccination Trial

OBJECTIVE Patients with latent autoimmune diabetes in adults (LADA) express autoantibodies against the 65-kDa isoform of GAD (GADA). Intervention with recombinant human GAD65 formulated with aluminium hydroxide (GAD-alum) given twice subcutaneously to LADA patients at intervals of 4 weeks was safe and did not compromise beta-cell function in a Phase II clinical trial. GADA affinity has been shown

Premedication for intubation in newborn infants; pain assessment, pharmacokinetics and pharmacodynamics

Popular Abstract in Swedish För tidigt födda barn genomgår intensivvård under en period när de är väldigt sårbara pga instabil cirkulation och ett omoget centralt nervsystem under snabb utveckling. Tillräcklig behandling av smärta är av största betydelse eftersom stark smärtupplevelse kan medföra skadliga omedelbara kroppsreaktioner, men också neurologiska och neuropsykologiska seneffekter. Det fiPreterm infants undergo intensive care during a vulnerable period with hemodynamic instability and a rapidly developing and immature CNS. Adequate pain management is essential, since pain experience might lead to acute physiological reactions as well as neurological and neuropsychological sequels. There is no “golden standard” for objective pain assessment, and no evidence-based recommendations fo

Atomic data for VUV lines of astrophysical interest in singly ionized rhodium

The first theoretical transition probabilities and oscillator strengths are reported for Rh II lines of astrophysical interest in the VUV region (100-200 nm). They have been obtained through the use of a pseudo-relativistic Hartree-Fock model including core-polarization effects and the accuracy has been estimated to be about 10-15% through a comparison with new experimental lifetimes measured usin

MafA and MafB Regulate Genes Critical to beta-Cells in a Unique Temporal Manner

OBJECTIVE-Several transcription factors are essential to pancreatic islet beta-cell development, proliferation, and activity, including MafA and MafB. However, MafA and MafB are distinct from others in regard to temporal and islet cell expression pattern, with beta-cells affected by MafB only during development and exclusively by MafA in the adult. Our aim was to define the functional relationship

Wax production from renewable feedstock using biocatalysts instead of fossil feedstock and conventional methods

Background, aim, and scope Using renewable feedstock and introducing biocatalysts in the chemical industry have been suggested as the key strategies to reduce the environmental impact of chemicals. The Swedish interdisciplinary research program "Speciality Chemicals from Renewable Resources-Greenchem" is aiming to develop these strategies. One target group of chemicals for Greenchem are wax esters

The presence of lateral photophores correlates with increased speciation in deep-sea bioluminescent sharks.

The vast majority of species within the lanternshark genus Etmopterus harbour complex luminescent markings on their flanks, whose functional significance has long remained obscure. Recent studies, however, suggest these enigmatic photophore aggregations to play a role in intraspecific communication. Using visual modelling based on in vivo luminescence measurements from a common lanternshark specie

Radar Observations of Arctic Bird Migration in the Beringia Region

Bird migration was recorded by tracking radar and visual observations in the Beringia region. The data were subdivided into seven areas extending from north of Wrangel Island southeastward toward the Bering Strait and then northwestward off the coast of Alaska to Point Barrow. The studies, which took place during a ship-based expedition between 30 July and 19 August 2005, recorded a total of 557 t

Rapid changes in bird community composition at multiple temporal and spatial scales in response to recent climate change

Although climate change is acknowledged to affect population dynamics and species distribution, details of how community composition is affected are still lacking. We investigate whether ongoing changes in bird community composition can be explained by contemporary changes in summer temperatures, using four independent long-term bird census schemes from Sweden (up to 57 yr); two at the national sc

Representation of microphysical processes in cloud-resolving models: Spectral (bin) microphysics versus bulk parameterization

Most atmospheric motions of different spatial scales and precipitation are closely related to phase transitions in clouds. The continuously increasing resolution of large-scale and mesoscale atmospheric models makes it feasible to treat the evolution of individual clouds. The explicit treatment of clouds requires the simulation of cloud microphysics. Two main approaches describing cloud microphysi

Vibration and Acoustic Damping of Flexible Polyurethane Foams Modified with a Hyperbranched Polymer

The dynamic mechanical properties and acoustic damping of polyurethane (PU) foams loaded with a hyperbranched polymer (HBP) have been studied. The results show a significant modulus enhancement parallel to an increased vibration damping in the low frequency range of approximate to 1 Hz with increased amount of HBP. Furthermore, an increased acoustic damping in the frequency interval of 500-1600 Hz

Purchasing strategies in industrialised building - A comparison of Australian and Swedish companies

Companies adopt different rationales for purchasing in order to make production processes as efficient as possible. This paper presents the results of an investigation into how purchasing strategies can vary between companies and countries. Two industrialised building companies, one in Sweden and one in Australia, were the objects of study. The purpose was to compare and understand the rationale b

Soil structure and salinity effects of fish farming as compared to traditional farming in northeastern Egypt

Recently, fish farming instead of traditional agriculture has been seen as a way to increase agricultural profits from saline affected land. Concerns, however, have been raised that fish farming may increase the salinity problems. In the salinity affected soils of the El-Salam canal project area in Egypt, farmers are giving tip traditional farming for fish farming due to possibilities to increase
