These guidelines provide clinically useful points to guide the management of UC in children. Taken together, the recommendations offer a standardized protocol that allows effective, timely management and monitoring of the disease course, while acknowledging that each patient is unique.

The paper presents the All-Russian consensus on the diagnosis and treatment of celiac disease in children and adults, which has been elaborated by leading experts, such as gastroenterologists and pediatricians of Russia on the basis of the existing Russian and international guidelines. The consensus approved at the 42nd Annual Scientific Session of the Central Research Institute of Gastroenterology on Principles of Evidence-Based Medicine into Clinical Practice (March 2-3, 2016). The consensus is intended for practitioners engaged in the management and treatment of patients with celiac disease. Evidence for the main provisions of the consensus was sought in electronic databases. In making recommendations, the main source was the publications included in the Cochrane Library, EMBASE, MEDLINE, and PubMed. The search depth was 10 years. Recommendations in the preliminary version were reviewed by independent experts. Voting was done by the Delphic polling system.

SrAl12O19:Pr phosphors have been investigated under ultraviolet/vacuum ultraviolet (5–20 eV) synchrotron radiation at room and near liquid He temperatures. The excitation of 1S 0 →1I 6 and 3P 0 →3H 4 emission of Pr3+ in SrAl12O19 occurs in a 1 eV wide region originating from the interconfiguration 4f2 → 4f5d transitions with threshold (onset of the transitions) at 6.0 eV at room temperature and at 6.15 eV at 14 K. A comparison of the excitation spectra of Pr3+ and known data for Ce3+ in SrAl12O19 reveals a shift of 1.52 eV between 5d states of the ions. The next threshold near 7.5 eV corresponds to the transitions from valence to conduction band. The luminescence from the 3P 0 level is excited efficiently at low temperature while 1S 0 luminescence is absent under band-to-band excitation. To explain this, a mechanism involving valence hole trapping and energy transfer from excitonic states to Pr3+ is proposed. At excitation near the maximum of 4f2 → 4f5d transitions (6.4 eV), the 1S 0 →1I 6 luminescence exhibits exponential decay with constant τ = 330 ± 10 ns at 300 K and τ ≈ 400 ns at 14 K. At pre-threshold excitation (E < 6.0 eV) a fast component τ ≈ 10 ns originating from excitonic emission prevails.

We have analyzed short-period geomagnetic pulsations measured by the north-south chain of pulsation magnetometers in Finland in association with the storm sudden commencement (SSC) recorded on September 22, 1999 at 12:22 UT. We observe that structured Pc 1 pulsations with amplitude modulation (modulation period is about 1000 seconds) were excited before the SSC whereas intense wave elements with rising frequency appear soon after SSC. It is concluded that the first effect is due to the interaction of the Earth's magnetosphere with the interplanetary foreshock region. The second one is likely the result of modification of Pc 1 waves due to interaction between the magnetosphere and the shock front structure leading to compression of the magnetosphere during the initial phase of the magnetic storm.
