High-precision Mass Measurements of 203-207Rn and 213Ra with SHIPTRAP
The masses of the nuclides Rn203-207 and Ra-213 were measured directly for the first time with the Penning-trap mass spectrometer SHIPTRAP at GSI Darmstadt. The results confirm the previously determined mass values. The mass uncertainties for Rn-205 and Ra-213 were significantly reduced. The results are relevant for the investigation of the nuclear shell structure between N = 82 and N = 126. As an
Deteriorated function of cutaneous microcirculation in chronic congestive heart failure
Background Chronic congestive heart failure is a complex condition that leads to dysfunction in the peripheral microcirculation. We have previously shown that vascular reactivity is reduced with increasing age. In this study, we examined a group of very old patients with severe chronic heart failure to test the hypothesis that vascular function is further compromised by a combination of heart fail
Feedback in the ERP Value-Chain: What Influence Has Thoughts about Competitive Advantage
Different opinions about whether an organization gains a competitiveadvantage (CA) from an enterprise resource planning (ERP) system exist. However, this paper describes another angle of the much reported competitive advantage discussion. The basic question in the paper concerns how thoughts about receiving competitive advantage from customizing ERPs influences feedback in ERP development. ERP dev
A study of the metal-rich, thick disk globular cluster NGC5927, A stellar inventory
We present a list of 72 radial velocity member stars in the metal-rich globular cluster NGC5927. The radial velocities are based on multiepoch, multifibre spectra. We identify 46 RGB/HB stars and 26 turn-off stars that are radial velocity members in the cluster. This cluster is situated quite close to the disk and hence fore-and/or background contamination, especially in the outskirts of the clust
Visualization of regulations to support design and quality control - a long-term study
The aim of the study was to visualize design regulations of furniture by means of interactive technology based on earlier studies and practical examples. The usage of the visualized regulations was evaluated on two occasions: at the start when the first set of regulations was presented, and after six years of usage of all regulations. The visualized regulations were the result of a design process
Calculation of the Molecular and Atomic Properties of Selected Anions in Water.
The polarizability and other properties have been studied for F(-), Cl(-), Br(-), and HCOO(-) in water using a combined quantum chemical statistical mechanics simulation model that explicitly takes into account the Pauli repulsion as well as the electrostatic coupling between the QM system and the classical surroundings. It is shown that the surrounding molecules significantly reduce both the pola
Diabetes Mellitus Glucose Prediction by Linear and Bayesian Ensemble Modeling
Diabetes Mellitus is a chronic disease of impaired blood glucose control due to degraded or absent bodily-specific insulin production, or utilization. To the affected, this in many cases implies relying on insulin injections and blood glucose measurements, in order to keep the blood glucose level within acceptable limits. Risks of developing short- and long-term complications, due to both too high
Det vardagliga och det vetenskapliga : Om sociologins begrepp
This dissertation concerns the relationship between sociology and everyday life and aims primarily to critically evaluate the positions taken in the theoretical discussion on sociological concept formation and its relation to everyday life and social sciences. The main theoretical positions in the debate are summarized in two ideal typological models: (1) The rationalist theory of an epistemologic
Collaborative Research: Examples from a Baltic Sea Project
Disability and health after replantation or revascularisation in the upper extremity in a population in southern Sweden - a retrospective long time follow up.
Replantation in the upper extremity is a well-established microsurgical procedure. Many have reported patients' satisfaction and functional measurements.The aim was to investigate the long time consequences as activity limitations in hand/arm, the general health and cold sensitivity after a replantation or revascularization in the upper extremity and to examine if sense of coherence (SOC) can be a
Patterns of functional enzyme activity in fungus farming ambrosia beetles
Introduction: In wood-dwelling fungus-farming weevils, the so-called ambrosia beetles (Curculionidae: Scolytinae and Platypodinae), wood in the excavated tunnels is used as a medium for cultivating fungi by the combined action of digging larvae (which create more space for the fungi to grow) and of adults sowing and pruning the fungus. The beetles are obligately dependent on the fungus that provid
Exposure to Polybrominated Diphenyl Ethers and Male Reproductive Function in Greenland, Poland and Ukraine.
Animal and a few human studies suggest that polybrominated diphenyl ethers (PBDEs) may affect male reproductive function. The aim of the present study was to evaluate if male reproductive function was associated with serum level of PBDEs. We evaluated, in a cross-sectional study, the effects of environmental exposure to BDE-47 and BDE-153 on reproductive hormones and semen quality, including marke
A framework for regularized non-negative matrix factorization, with application to the analysis of gene expression data.
Non-negative matrix factorization (NMF) condenses high-dimensional data into lower-dimensional models subject to the requirement that data can only be added, never subtracted. However, the NMF problem does not have a unique solution, creating a need for additional constraints (regularization constraints) to promote informative solutions. Regularized NMF problems are more complicated than conventio
Association of a hydrophobically modified polyelectrolyte and a block copolymer followed by fluorescence techniques
By using absorption and fluorescence (steady-state and time-resolved) techniques the interaction between a poly(acrylic acid) PAA, randomly grafted with pyrene (Py) units (PAAMePy55) and a triblock copolymer of poly(ethylene oxide) and poly(propylene oxide) (EO20PO68EO20, P123) was investigated. From the fluorescence data it is shown that upon addition of P123 a decrease of the (pyrene-pyrene, Py-
Predicting long-term carbon sequestration in response to CO2 enrichment: How and why do current ecosystem models differ?
Large uncertainty exists in model projections of the land carbon (C) sink response to increasing atmospheric CO2. Free-Air CO2 Enrichment (FACE) experiments lasting a decade or more have investigated ecosystem responses to a step change in atmospheric CO2 concentration. To interpret FACE results in the context of gradual increases in atmospheric CO2 over decades to centuries, we used a suite of se
Long-term benefits of progressive resistance training in chronic stroke: A 4-year follow-up.
OBJECTIVES: To evaluate the long-term benefits of progressive resistance training in chronic stroke. DESIGN: A 4-year follow-up of a randomized controlled trial of progressive resistance training. SUBJECTS: Eighteen women and men (mean age 66 (standard deviation 4) from the original group of 24 post-stroke participants. METHODS: The training group (n = 11) had participated in supervised progres

A note on the optimal level of monetary aggregation in the United Kingdom
Weak separability is a key admissibility property in the Divisia approach to monetary aggregation. We test groups of U.K. household sector monetary assets for weak separability using new data underlying the Bank of England's benchmark revision of its household sector Divisia index. Nonparametric tests are used to identify four monetary asset groupings, which are weakly separable over all or almost
Current knowledge and importance of dGEMRIC techniques in diagnosis of hip joint diseases
Accurate assessment of early hip joint cartilage alterations may help optimize patient selection and follow-up of hip joint preservation surgery. Delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) is sensitive to the glycosaminoglycan content in cartilage that is lost early in the development of osteoarthritis (OA). Hence, the dGEMRIC technique holds promise for the deve
