Isospin dependence of electromagnetic transition strengths among an isobaric triplet

Electric quadrupole matrix elements, Mp, for the Jπ=2+→0+, ΔT=0, T=1 transitions across the A=46 isobaric multiplet 46Cr-46V-46Ti have been measured at GSI with the FRS-LYCCA-AGATA setup. This allows direct insight into the isospin purity of the states of interest by testing the linearity of Mp with respect to Tz. Pairs of nuclei in the T=1 triplet were studied using identical reaction mechanisms

Peel testing of a packaging material laminate studied by in-situ X-ray tomography and cohesive zone modeling

Peel testing is used to study adhesive fracture in packaging material laminates. The focus is on improved understanding of the mechanisms that provide a laminate's adhesive properties, as measured by standard macroscopic tests. Using a specially-designed peel test load rig, peel tests are performed in-situ in a laboratory X-ray tomograph. The peel test results are analyzed using a combination of tPeel testing is used to study adhesive fracture in packaging material laminates.

Analysis of Age of Information threshold violations

We study a scenario where a monitor is interested in the freshest possible update from a remote sensor. The monitor also seeks to minimize the number of updates that exceed a certain freshness threshold, beyond which, the information is deemed to be too old. Previous work has presented results for First Come First Served (FCFS) systems. However, it has been shown that Last Come First Served (LCFS)We study a scenario where a monitor is interested in the freshest possible update from a remote sensor.

It's Part of Me, Not All of Me : Young Women's Experiences of Receiving a Diagnosis Related to Diverse Sex Development

Study Objective: To understand young women's experiences of receiving a diagnosis related to diverse sex development.Design: A qualitative narrative analysis of interviews.Setting: Karolinska University Hospital.Participants: Nine women (aged 20-26 years) with complete androgen insensitivity syndrome, XY or XX gonadal dysgenesis.Interventions: Semistructured interviews.Main Outcome Measures: A nar

From knowing nothing to knowing what, how and now : Parents' experiences of caring for their children with Congenital Adrenal Hyperplasia.

Objective This study investigates various kinds of knowing that European parents use when caring for their children with congenital adrenal hyperplasia (CAH). Methods Semi-structured qualitative interviews with 20 parents of 22 children with CAH. Results Parents emphasized the importance of knowing what CAH is and what support their child needs, but also knowing how to cope and make sense of the n

Subdividing the Holocene Series/Epoch : formalization of stages/ages and subseries/subepochs, and designation of GSSPs and auxiliary stratotypes

The Holocene, which currently spans ~11 700 years, is the shortest series/epoch within the geological time scale (GTS), yet it contains a rich archive of evidence in stratigraphical contexts that are frequently continuous and often preserved at high levels of resolution. On 14 June 2018, the Executive Committee of the International Union of Geological Sciences formally ratified a proposal to subdi

Land-use planning for sustainable urban development in africa : A spatial and multi-objective optimization approach

Land-use planning, which requires finding a balance among different conflicting social, economic and environment factors, is a complex task needed everywhere, including Africa. One example is the city of Zanzibar in Tanzania, which is under special consideration for land-use revision. From one side, the city has high potentials for tourist industry and at the other side there are major challenges

Quantitative determination of islet cell surface antibodies using 125I-protein A

A quantitative method to measure islet cell surface antibodies in human patients has been developed using 125I-protein A. Isolated, dispersed, viable rat islet cells prepared by collagenase digestion were fixed in 4% paraformaldehyde to allow storage for up to 7 wk at 4°C. Human sera, heat inactivated and adsorbed with rat liver and kidney powder (100 mg/ml), were incubated with the fixed cells (5

Measurement of jet radial profiles in Pb–Pb collisions at sNN=2.76 TeV

The jet radial structure and particle transverse momentum (pT) composition within jets are presented in centrality-selected Pb–Pb collisions at sNN=2.76 TeV. Track-based jets, which are also called charged jets, were reconstructed with a resolution parameter of R=0.3 at midrapidity |ηch jet|

Real time MRI to elucidate the functionality of coating films intended for modified release

Polymer films based on mixtures of ethyl cellulose (EC) and hydroxypropyl cellulose (HPC) have been widely used to coat pellets and tablets to modify the release profile of drugs. For three different EC/HPC films we used 1H and 19F MRI in combination with a designed release cell to monitor the drug, polymer and water in 5 dimensional (5D) datasets; three spatial, one diffusion or relaxation and a

Measurement of prompt photon production in sNN=8.16 TeV p + Pb collisions with ATLAS

The inclusive production rates of isolated, prompt photons in p+Pb collisions at sNN=8.16 TeV are studied with the ATLAS detector at the Large Hadron Collider using a dataset with an integrated luminosity of 165 nb−1 recorded in 2016. The cross-section and nuclear modification factor RpPb are measured as a function of photon transverse energy from 20 GeV to 550 GeV and in three nucleon–nucleon cen

Radiographers’ perspectives’ on Visual Grading Analysis as a scientific method to evaluate image quality

Introduction: Radiographers routinely undertake many initiatives to balance image quality with radiation dose (optimisation). For optimisation studies to be successful image quality needs to be carefully evaluated. Purpose was to 1) discuss the strengths and limitations of a Visual Grading Analysis (VGA) method for image quality evaluation and 2) to outline the method from a radiographer's perspec

Investigation of autofluorescence in zooplankton for use in classification of larval salmon lice

We present autofluorescence of six zooplankton species, including salmon lice (Lepeophtheirus salmonis), for the purpose of classification in marine environments. Using a 410 nm excitation wavelength, we find that all measured zooplankton species exhibit broad cyan fluorescence centered around 510–520 nm. Furthermore, salmon lice show an absence of red fluorescence from undigested chlorophyll, whi

Animal Signals : Dirty Dancing in the Dark?

The use of highly visible body colours as signals during courtship is well known from animals active in brighter light. Now a sexually dimorphic colouration signal has been discovered in a nocturnal moth, suggesting that visual courtship rituals might even occur at night.
