Modeling of Continuous Dynamic Recrystallization in Aluminum

A constitutive model is presented, considering grain size refinement through continuous dynamic recrystallization together with an evolving dislocation density. The grain refinement is allowed to influence both the evolution of the dislocation density and the rate dependence of the material. The model is calibrated against experimental data on aluminum and numerical simulations of equal channel an

Prevention of Acute and Chronic Allograft Rejection by Combinations of Tolerogenic Dendritic Cells

It is well known that adoptive transfer of donor-derived tolerogenic dendritic cells (DC) helps to reduce acute allograft rejection. However, this method cannot effectively prevent grafts from infiltration of inflammatory cells and fibrosis, and thus has minimal effect on chronic allograft rejection. In this study, we used mitomycin C (MMC) to generate tolerogenic DC and demonstrated that donor (B

TASISpec - A Highly Efficient Multi-coincidence Spectrometer for Nuclear Structure Investigations of the Heaviest Nuclei

TASISpec (TASCA in Small Image mode Spectroscopy) combines composite Ge- and Si-detectors for a new detector setup aimed towards multi-coincidence gamma -ray, X-ray, conversion electron, fission fragment, and a-particle spectroscopy of the heaviest nuclei. It exploits the TASCA separator's unique small image focal mode, i.e. the fact that evaporation residues produced in fusion-evaporation reactio

Thou shalt not pass? Examining the existence of an immigrant glass ceiling in Sweden, 1970-1990

The paper studies a sample of natives and 18 immigrant nationalities in the Swedish labor market between 1970 and 1990. The purpose is examining the existence of an immigrant specific glass ceiling. Results suggest a considerable overall advantage in terms of the probability of experiencing upward occupational mobility for native Swedish males. Despite this, the pattern does not correspond to the

Timing of surgery for hip fracture and in-hospital mortality: a retrospective population-based cohort study in the Spanish National Health System

Background: While the benefits or otherwise of early hip fracture repair is a long-running controversy with studies showing contradictory results, this practice is being adopted as a quality indicator in several health care organizations. The aim of this study is to analyze the association between early hip fracture repair and in-hospital mortality in elderly people attending public hospitals in t

Does antenatal care facilitate utilization of emergency obstetric care? A case-referent study of near-miss morbidity in Bolivia

Objective. To determine whether lack of routine antenatal care (ANC) is associated with near-miss morbidity upon arrival at hospital. Design. Case-referent study. Setting. Four maternity hospitals in La Paz and El Alto, Bolivia, where free maternal health care is provided through a government subsidized program. Sample. Women with severe maternal morbidity upon arrival at hospital (n = 297). Facil

Search for WH production with a light Higgs boson decaying to prompt electron-jets in proton-proton collisions at root s=7 TeV with the ATLAS detector

A search is performed for WH production with a light Higgs boson decaying to hidden-sector particles resulting in clusters of collimated electrons, known as electron-jets. The search is performed with 2.04 fb(-1) of data collected in 2011 with the ATLAS detector at the Large Hadron Collider in proton-proton collisions at root s = 7 TeV. One event satisfying the signal selection criteria is observe

A model for drop size prediction during cross-flow emulsification

The formation of drops is a topic of great interest in a wide variety of engineering applications, such as membrane emulsification. In order to develop an improved force balance model that is capable of predicting the final size of the detached drop, the formation of drops into a cross-flowing continuous phase has been studied with computational fluid dynamics (CFD). The force balance developed ta

Preoccupied by the Past. The Case of Estonanian´s Mueum of Occupations

The article is an analysis of the Okupatsioonide Museum, The Museum of the Occupations, in Tallinn, Estonia. The analysis deals both with the content of the exhibition as well as well as the monuments of former Communists in its basement, It alse deals with "the power of place", the location of the museum and its importance in Tallinn´s "cityscape".

Ternary q-Virasoro-Witt Hom-Nambu-Lie algebras

In this paper we construct ternary q-Virasoro-Witt algebras which q-deform the ternary Virasoro-Witt algebras constructed by Curtright, Fairlie and Zachos using su(1, 1) enveloping algebra techniques. The ternary Virasoro-Witt algebras constructed by Curtright, Fairlie and Zachos depend on a parameter and are not Nambu-Lie algebras for all but finitely many values of this parameter. For the parame

Climatology of the Iberia coastal low-level wind jet: weather research forecasting model high-resolution results

Coastal low-level jets (CLLJ) are a low-tropospheric wind feature driven by the pressure gradient produced by a sharp contrast between high temperatures over land and lower temperatures over the sea. This contrast between the cold ocean and the warm land in the summer is intensified by the impact of the coastal parallel winds on the ocean generating upwelling currents, sharpening the temperature g

Search for long-lived, heavy particles in final states with a muon and multi-track displaced vertex in proton-proton collisions at root s=7 TeV with the ATLAS detector

Many extensions of the Standard Model posit the existence of heavy particles with long lifetimes. In this Letter, results are presented of a search for events containing one or more such particles, which decay at a significant distance from their production point, using a final state containing charged hadrons and an associated muon. This analysis uses a data sample of proton-proton collisions at

Terrestrial organic matter support of lake food webs : evidence from lake metabolism and stable hydrogen isotopes of consumers

We quantified the utilization of terrestrial organic matter (OM) in the food web of a humic lake by analyzing the metabolism and the consumers' stable isotopic (C, H, N) composition in benthic and pelagic habitats. Terrestrial OM inputs (3 g C m(-2) d(-1)) to the lake greatly exceeded autochthonous OM production (3 mg C m(-2) d(-1)) in the lake. Heterotrophic bacterial growth (19 mg C m(-2) d(-1))

One vs Three Years of Adjuvant Imatinib for Operable Gastrointestinal Stromal Tumor : A Randomized Trial

Context Adjuvant imatinib administered for 12 months after surgery has improved recurrence-free survival (RFS) of patients with operable gastrointestinal stromal tumor (GIST) compared with placebo. Objective To investigate the role of imatinib administration duration as adjuvant treatment of patients who have a high estimated risk for GIST recurrence after surgery. Design, Setting, and Patients Pa

Assessing atmospheric nitrogen deposition to natural and semi-natural ecosystems - Experience from Danish studies using the DAMOS

Local agricultural emissions contribute significantly to the atmospheric reactive nitrogen loads of Danish terrestrial ecosystems. In the vicinity of the sources this may be up to 6-8 kg N ha(-1) yr(-1) depending on location and ecosystem type. This contribution arises from dry deposition of gas phase ammonia derived from local livestock production. Long-range transport, however, often constitutes
