Following the severe attacks by the so-called ´Islamic State of Iraq and Syria' (ISIS) on the Yazidi population, which started in summer 2014, the state government of Baden-Württemberg, Germany, funded a Special-Quota Project to bring 1000 very ill or left-behind women and children who were being held hostage to 22 cities and towns in Baden-Württemberg to receive integrated care.

Patients and methods Secondary data from the statutory health insurance Gmnder Ersatzkasse (GEK) of the year 2009 were analyzed. Continuously insured children with psoriasis vulgaris were identified by ICD‐10 codes (L 40. X). Their treatment was determined on the basis of prescriptions according to ATC code. Results 1,313 of 293,181 children and adolescents had psoriasis (0.45%). Of these, n = 651 ( ...

The propagation of nuclear polaritons through a scattering system composed of two spatially separated targets was studied. The stainless-steel targets were highly enriched in resonant $^{57}\mathrm{Fe}$ nuclei and had different thicknesses, and, in addition, the resonance width of one target could be increased by cooling it to low temperatures. A nuclear polariton state was created in both targets almost instantly by a short flash of synchrotron radiation. The propagation of the polariton could be ...

The lattice parameters of α-Al 2 O 3 have been measured in a temperature range from 4.5 to 250 K with a relative accuracy of better than 6 × 10 −6 . The experimental method uses Bragg backscattering and the recently proposed Mössbauer wavelength standard, i.e. the wavelength λ M = 86.025474 (16) pm of the nuclear resonance radiation of 57 Fe (Shvyd'ko et al. , 2000), which has previously been applied successfully to measure the lattice parameters of α-Al 2 O 3 at temperatures between 286 and 374 K (Shvyd'ko ...

We demonstrate an interferometer for hard x rays with two back-reflecting sapphire crystal mirrors--a prototype x-ray Fabry-Pérot interferometer. A finesse of 15 and 0.76 mu eV broad Fabry-Pérot transmission resonances are measured by the time response of the interferometer. Interference patterns are observed directly in spectral dependences of reflectivity.

The nuclear forward scattering of synchrotron radiation (NFSSR) of two spatially separated but otherwise identical stainless-steel targets is strongly influenced by the application of approximately stepwise Doppler energy shifts to one of the targets in synchronization with the synchrotron radiation (SR) pulse. The decisive role of radiative coupling in NFSSR, i.e., the influence of the radiation field emitted by the upstream target on the oscillators of the downstream target, has been clarified in ...

The difference Delta(a)=a(30)-a(28) of the lattice parameter of 30Si and 28Si crystals is measured over a temperature range from 4.7 to 700 K. In disagreement with existing knowledge, the strongest isotopic effect is not detected at the lowest achieved temperature T=4.7 K. An anomalous behavior is observed: The relative difference |Delta(a)/a| attains its maximum value of 56.8(5) ppm at T=75(10) K. The anomalous behavior is attributed to the influence of phonon modes with negative Grüneisen parameters. ...

The newly proposed atomic-scale length standard, the wavelength of the 57Fe Mössbauer radiation [Shvyd'ko et al. (2000). Phys. Rev.

Nuclear resonant scattering of synchrotron radiation from the 25.6 keV level of 161Dy is studied with two techniques: nuclear forward scattering (NFS) and nuclear incoherent scattering (NIS). NFS time spectra of Dy metal are measured at temperatures ranging from 15 K to 80 K. They reveal electron spin relaxation in ferromagnetic dysprosium with long relaxation times of ≃ 10–30 ns. NIS energy spectra of Dy2O3 at room temperature are measured with meV resolution. Scattering accompanied by phonon excitation ...

The theory of an X-ray Fabry-Perot interferometer (FPI) is developed as a particular case of the dynamical theory of X-ray Bragg diffraction in layered crystalline systems. Mathematical expressions are derived for the transmissivity and reflectivity of the X-ray FPI built as a system of two perfect crystal plates parallel to each other. The performance of the X-ray FPI is similar to that of the optical FPI. Both show fine interference structure in the transmission and reflection dependences. However, ...

The wavelength of the 57Fe Mössbauer radiation is measured with a relative uncertainty of 0.19 ppm by using almost exact Bragg backscattering from a reference silicon crystal. Its value is determined as lambda(M) = 0.860 254 74(16)x10(-10) m. The corresponding Mössbauer photon energy is E(M) = 14 412.497(3) eV. The wavelength of the 57Fe Mössbauer radiation is easily reproducible with an accuracy of at least 10(-11)lambda(M) and could be used as a length standard of atomic dimensions.
