Background: The existence of a “minority tax,” defined as the burden of extra responsibilities placed on minorities relative to non-minorities of the same position, has been documented across various fields, including and beyond medicine. This study sought to quantify the types and extent of the minority tax faced by minority orthopaedic surgeons, as well as evaluate the degree to which this work

The Öresund – the strait between eastern Denmark and southwestern Sweden – is an ancient focal point for trade, conflict, and cooperation in Northern Europe. The control of the strait has been of utmost strategic importance in Northern Europe over the centuries, involving several wars between Denmark and Sweden. During the 19th and 20th centuries, a decidedly more peaceful relationship developed

Reglerna som möjliggör stängning av hemsidor på internet präglas av godtycke och otydlighet. Men det behöver inte vara särskilt svårt att skapa ett nytt och rättssäkert regelverk. Här har Sveriges EU-kommissionär Cecilia Malmström en viktig roll. Frågan är om hon tar sitt ansvar, skriver politiker och nätdebattörer.

A new approach to low-complexity channel estimation in orthogonal-frequency division multiplexing (OFDM) systems is proposed. A low-rank approximation is applied to a linear minimum mean-squared error (LMMSE) estimator that uses the frequency correlation of the channel. By using the singular value decomposition (SVD) an optimal low-rank estimator is derived, where performance is essentially preser

Civil Society Elites? Power, stratification and diversity in European civil societies Despite a long fascination with processes leading to the concentration of power and resources in different arenas of social, political, and financial life, social science scholars have not explored the possibility of a civil society elite or the implications for the roles that civil society can and is expected to

Hybrid zones present a unique framework to study the genetic basis of reproductive isolation and speciation. The European fire-bellied toad (Bombina bombina) and yellow-bellied toad (B. variegata) hybridize in a zone across several thousand kilometres in Central Europe. The Bombina system has been examined for more than a century and its scientific legacy comprises the development of the ultilocus

Purpose – This paper aims to develop a novel micro-ablation system to realise micrometric and well-defined hydrogel structures. To engineer a tissue it is necessary to evaluate several aspects, such as cell-cell and cell-substrate interactions, its micro-architecture and mechanical stimuli that act on it. For this reason, it is important to fabricate a substrate which presents a microtopology simi

Recent research suggests that multilingual students tend to use their complete language repertoires, particularly their L1, when writing in a non-native language (e.g. Cenoz & Gorter 2011; Wang 2003). While there is some international research on the L2 and L3 writing process among bilinguals, the L2/L3writing process of bilingual and multilingual individuals in the Swedish context remains une

High-resolution photoelectron spectra of the inner- shell levels of molecular oxygen have been measured using synchrotron radiation. The vibrational structure of the two magnetically-split core-shell components is analyzed based upon ab initio calculations. The ratio between the intensities of the two components was analyzed at several different ionization energies up to about 600 eV, and the same

Establishing an advanced European bioeconomy is an important step in achieving the transition towards sustainable development and away from fossil fuels. The bioeconomy can be defined as an economy based on the sustainable production and conversion of renewable biomass into a range of bio-based products, chemicals, and energy. Several strategies have been produced in Europe from different perspect

A hollow fiber supported liquid membrane module using one single fiber impregnated with a mixture of 1,10-dibenzyl-1,10-diaza-18-crown-6 and bis(2-ethylhexyl)phosphate dissolved in hexylbenzene was used for passive sampling of ppb levels of Pb(II), Cu(II), Zn(II), Mn(II), Ni(II), and Cd(II) in water. The target ions were simultaneously transported and preconcentrated into a citric acid acceptor so

The removal of particulate fine fractions by a proper high-temperature cleaning device is a very important issue in the development of the biorefinery concept. Therefore, in this investigation, particles from a 100 kW(th) steam-O-2 blown circulating fluidized-bed (CFB) gasifier were sampled and characterized. The sampling was performed with a specially designed heated dilution probe downstream of

Prenatal diagnosis in the third pregnancy of a mother who already had one healthy son and one son with Fanconi anaemia (FA), revealed that her fetus was also affected with FA. At 22 weeks a maternal complaint about excessive fetal kicking starting at 15 weeks, focused our attention on the behaviour of the fetus, which was observed by means of real-time ultrasound for 30 min. The differentiation of

A high excess mortality is well described after hip fracture. Deaths are in part related to comorbidity and in part due directly or indirectly to the hip fracture event itself (causally related deaths). The aim of this study was to examine the quantum and pattern of mortality following hip fracture. We studied 160,000 hip fractures in men and women aged 50 years or more, in 28.8 million person-yea

High-level quantum-chemical methods show that the binding in the inclusion complex of hexamethylbenzene (HMB) in 6-cycloparaphenitacetylene (6-CPPA) cannot be explained only in terms of electrostatic interactions-caused by the polarization associated to curved a-conjugated systems-and the inclusion of dispersion forces is definitely needed. The theoretical description of van der Wools interactions

Measurements of the adiabatic laminar burning velocities of n-heptane, iso-octane, ethanol and their binary and tertiary mixtures are reported. Non-stretched flames were stabilized on a perforated plate burner at 1 atm. The Heat Flux method was used to determine burning velocities under conditions when the net heat loss from the flame to the burner is zero. Initial temperatures of the gas mixtures

BACKGROUND: Female sex pheromones attracting mating partners over long distances are a major determinant of reproductive isolation and speciation in Lepidoptera. Males can also produce sex pheromones but their study, particularly in butterflies, has received little attention. A detailed comparison of sex pheromones in male butterflies with those of female moths would reveal patterns of conservatio

Fischer-Tropsch (FT) synthesis is an important process in the manufacturing of hydrocarbons and oxygenated hydrocarbons from mixtures of carbon monoxide and hydrogen (syngas). The reduced iron catalyst reacts with carbon monoxide and hydrogen to form bulk Fe5C2 Hagg carbide (chi-HC) during FT synthesis. Arguably, chi-HC is the predominant catalyst phase present in the working iron catalyst. Deacti
