Study of the efficiency of profile subjects taught to students of the dental faculty from the first semester of the first year

The purpose of the study is to find out the differences in knowledge and attitude to oral hygiene among the first and second–year students as well as fourth and fifth-year students of USMU Faculty of Dentistry to assess the effectiveness of teaching junior students the profile subjects.Цель исследования – выявление отличий в знаниях и отношении к гигиене полости рта между студентами 1–2 и 4–5 курсов стоматологического факультета УГМУ для оценки эффективности обучения студентов 1–2 курсов профильным предметам

Searching for gravitational waves from known pulsars

We present upper limits on the amplitude of gravitational waves from 28 isolated pulsars using data from the second science run of LIGO. The results are also expressed as a constraint on the pulsars' equatorial ellipticities. We discuss a new way of presenting such ellipticity upper limits that takes account of the uncertainties of the pulsar moment of inertia. We also extend our previous method to search for known pulsars in binary systems, of which there are about 80 in the sensitive frequency range of LIGO and GEO 600.Comment: Accepted by CQG for the proceeding of GWDAW9, 7 pages, 2 figure

Influence of host matrices on krypton electron binding energies and KLL Auger transition energies

The low-energy electron spectra emitted in the radioactive decay of the 83Rb and 83Sr isotopes were measured with a combined electrostatic electron spectrometer. Radioactive sources used were prepared by ion implantation of 83Sr into a high purity polycrystalline platinum foil at 30 keV and by vacuum-evaporation deposition of 83Rb on the same type of foil. From the measured conversion electron spectra, the electron binding energies (referenced to the Fermi level) for the K, L1, L2, L3, M1, M2, and M3 shell/subshells of krypton in the platinum host were determined to be 14316.4(12), 1914.3(9), 1720.3(9), 1667.6(9), 281.5(9), 209.6(13), and 201.2(15) eV, respectively, and those for the evaporated layer were observed to be lower by 0.7(1) eV. For both host matrices, values of 2.3(2), 4.6(2), 1.7(2), 1.3(2), and 3.2(3) eV were obtained for the krypton K, L1, L2, L3, and M1 natural atomic level widths, respectively. The absolute energies of 10838.5(9) and 10839.5(10) eV were measured for the KL2L3(1D2) Auger transition in krypton implanted in Pt and generated in the evaporated rubidium layer, respectively. A value of 601.0(8) eV was measured for the energy difference of the KL2L3(1D2) transitions in Rb and Kr in the Pt host. Multiconfiguration Dirac-Fock calculations of the krypton KLL transition energies and intensities were also performed

Search for double beta decay of 106^{106}Cd in the TGV-2 experiment

International audienceA new experimental run of searching for double beta decay of (106)Cd was performed at the Modane underground laboratory (LSM, France, 4800 m w.e.) using the TGV-2 spectrometer, consisting of 32 planar type HPGe detectors with a total sensitive volume of ~400 cm(3). 16 foils of (106)Cd with an enrichment of 99.57% and a total mass of ~ 23.2 g were inserted between the entrance windows of face-to-face detectors. The limit on 2vEC/EC decay of (106)Cd - T(1/2) > 3.7 × 10(20) y at 90% C.F was obtained from the preliminary calculation of experimental data accumulated for 8198 h of measurement. The limits on the resonance OvEC/EC decay of (106)Cd were obtained from the measurement of ~23.2 g of (106)Cd with the low-background HPGe spectrometer Obelix lasted 395 h -T(1/2) (KF, 2741 keV) > 0.9 × 10(20) y and T(1/2) (KK, 2718 keV) > 1.4 × 10(20) y at 90% C.L
