Preparation and double-helix icosahedra structure of δ-Co2Zn15

The first known example of a regular face-sharing icosahedra helix is presented in the novel crystal structure of δCo2Zn15, solved and refined from single-crystal X-ray and neutron powder diffraction data. The compound δCo2Zn15 is also the first example of an intermetallic compound crystallizing in the acentric hexagonal space group P62. The parameters from the single crystal refinement are a = 11

Structure of Dy13Zn57 a binary quasicrystal approximant

The title compound Dy13Zn57, crystallizes in the orthorhombic space group Pnma (No. 62) with the cell parameters a = 14.060(5), b = 14.260(5) and c = 24.700(3) Å. The structure has formerly been described as Dy13Zn58 with the hexagonal type structure of Gd13Zn58. Single-crystal X-ray diffraction measurements however, show extra reflections breaking the C-centering of the corresponding orthorhombic

Skin exposure to the rubber accelerator diphenylguanidine in medical gloves—An experimental study

Background: Dermatitis caused by occupational contact allergy to rubber additives such as diphenylguanidine (DPG) in medical gloves is a hazard for healthcare workers. Both the duration of exposure to medical gloves and the number of gloves used per day vary. The use of alcoholic skin disinfectants before glove donning is mandatory. Objectives: To assess whether skin exposure to the rubber acceler

Dynamics in the Szegő class and polynomial asymptotics

We introduce the Szegő class, Sz(E), for an arbitrary Parreau–Widom set E ⊂ ℝ and study the dynamics of its elements under the left shift. When the direct Cauchy theorem holds on ℂ\E, we show that to each J ∈ Sz(E) there is a unique element J′ in the isospectral torus, T E , so that the left-shifts of J are asymptotic to the orbit {J′ m } on T E . Moreover, we show that the ratio of the associ

Estimating glomerular filtration rate at the transition from pediatric to adult care

The current Kidney Disease Improving Global Outcomes (KDIGO) guidelines recommend the use of the bedside creatinine-based Chronic Kidney Disease in Children (CKiD) equation to estimate glomerular filtration rate (GFR) in children and the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation in adults. However, this approach causes implausible changes in estimated GFR (eGFR) at the

On the molecular interactions in lipid bilayer-water assemblies of different curvatures

This work concerns the importance of intermolecular interactions present in aqueous lipid assembly systems depending on the type of aggregates they form. We have studied aqueous mixtures of diglycerol monooleate, Capmul glycerol monoleate (GMO-50) and polyoxyethylene (20) sorbitan monooleate (Polysorbate 80, P80) using small-angle X-ray scattering (SAXS) measurements to reveal the structure of liq

Learning from Okinawa’s geopolitical history: how easing the burden of the bases makes good geopolitical sense

This chapter examines the contemporary geopolitical challenges facing Okinawa by considering the geopolitical history of the islands. It pays particular attention to the events precipitating the Meiji Restoration, and of the subsequent Meiji Era. Meiji may have led to the modernization of Japan, but imperial policy relegated Okinawa to economic-backwater status, and of course eventually the island

Treatment following myocardial infarction in patients with schizophrenia

Background A correlation between excess mortality from myocardial infarctions (MI) and schizophrenia has already been established. What remains unclear is whether the initial communication between the treating doctor and the corresponding patient contributes to this excess mortality. Aim The aim of this study is to investigate whether a patient with schizophrenia receives the same offers for exami

Modeling of grain growth under fully anisotropic grain boundary energy

A level set formulation is proposed that can accurately trace the evolution of grain boundary networks in a polycrystalline aggregate while respecting grain boundary energy anisotropy. Commonly adopted simplifying assumptions related to the grain boundary energy variation with local microstructure conditions are avoided and the grain boundary energy dependence on both crystallographic misorientati

Vetenskap och beprövad erfarenhet - socialtjänst

Detta är den sjunde publikationen i en serie småskrifter som alla handlar om vetenskap och beprövad erfarenhet. Denna gång ligger fokus på socialtjänsten. I de tidigare skrifterna i denna serie har det framkommit hur viktigt be- greppet vetenskap och beprövad erfarenhet är för en rad verksamhetsområden, till exempel medicin, skola och poli- tik. Inte att förglömma begreppet eller begre

Strikes and Lockouts in Sweden : Reconsidering Raphael’s List of Work Stoppages 1859-1902

This paper presents and discusses a recently digitized, dataset of strikes and lockouts in Sweden for the period 1859-1902. The dataset, which originally was collected by Axel Raphael by retrospectively browsing through newspapers, pre-dates the Swedish official statistics on work stoppages that began in 1903. Whereas Raphael’s data have been used to illustrate the long-run development of strikes,

Effect of delayed vs early umbilical cord clamping on iron status and neurodevelopment at age 12 months a randomized clinical trial

IMPORTANCE Prevention of iron deficiency in infancymay promote neurodevelopment. Delayed cord clamping (DCC) can prevent iron deficiency during the first 6 months of life. However, no data are available on long-term effects on infant outcomes in relation to time for umbilical cord clamping. OBJECTIVE To investigate effects of DCC, as compared with early cord clamping (ECC), on infant iron status a

SMITE : A toolbox for creating Psychophysics Toolbox and PsychoPy experiments with SMI eye trackers

We present SMITE, a toolbox for the measurement of eye movements using eye trackers manufactured by SMI GmbH. The toolbox provides a wrapper around the iViewX SDK provided by SMI, allowing simple integration of SMI eye trackers into Psychophysics Toolbox and PsychoPy programs. The toolbox provides a graphical interface for participant setup and calibration that is implemented natively in Psychophy

Duplication assessments in Brassica vegetable accessions

There is extensive duplication of accessions among collection holders globally. To save costs, unwanted duplication should be avoided. This issue has been addressed internationally. In Europe, there are currently 35 Brassica collections located in 24 countries. Duplication may be identified not only by surveying passport data and seed transactions, but also by applying morphological or genetic cha
