Awareness of oral health prophylaxis in pregnant women
Introduction: During pregnancy, changes in the oral cavity occur due to fluctuations in
hormone levels and changes in eating habits and hygiene. Objectives: To evaluate pregnant women’s awareness of oral health prophylaxis. Material and Methods: An anonymous questionnaire was completed by 341 pregnant women from
Malopolskie Voivodeship. The statistical analysis was carried out in the R program (v. 3.4.3); a p-value <0.05 was considered significant. Results: Over half of the respondents did not receive oral hygiene instruction and did not take part in any prophylactic program. The main sources of oral health knowledge were the internet (66.3%), dentist (43.1%) and gynaecologist (17.9%). Respondents willingly followed the advice of healthcare workers. Approximately 32% of the surveyed women were aware of the most appropriate period for dental treatment (second trimester). Over half of the women admitted that they would receive dental care more often if more procedures were reimbursed. Approximately 71% of the women were aware of the increased susceptibility to tooth decay during pregnancy. The relationship between the presence of caries in parents
and that in children was known by 42.1% of respondents, but 45% admitted they did not know how to take care of their child’s teeth properly. Conclusions: Women with a higher education level had better knowledge in the area of oral health. However, most of the respondents need to increase their knowledge in this area. Prophylactic programs
should be broadly propagated, and healthcare workers should deliver essential information in daily practice
NA61/SHINE facility at the CERN SPS: beams and detector system
NA61/SHINE (SPS Heavy Ion and Neutrino Experiment) is a multi-purpose
experimental facility to study hadron production in hadron-proton,
hadron-nucleus and nucleus-nucleus collisions at the CERN Super Proton
Synchrotron. It recorded the first physics data with hadron beams in 2009 and
with ion beams (secondary 7Be beams) in 2011.
NA61/SHINE has greatly profited from the long development of the CERN proton
and ion sources and the accelerator chain as well as the H2 beamline of the
CERN North Area. The latter has recently been modified to also serve as a
fragment separator as needed to produce the Be beams for NA61/SHINE. Numerous
components of the NA61/SHINE set-up were inherited from its predecessors, in
particular, the last one, the NA49 experiment. Important new detectors and
upgrades of the legacy equipment were introduced by the NA61/SHINE
Collaboration.
This paper describes the state of the NA61/SHINE facility - the beams and the
detector system - before the CERN Long Shutdown I, which started in March 2013
Two-particle correlations in azimuthal angle and pseudorapidity in inelastic p + p interactions at the CERN Super Proton Synchrotron
Results on two-particle ΔηΔϕ correlations in inelastic p + p interactions at 20, 31, 40, 80, and 158 GeV/c are presented. The measurements were performed using the large acceptance NA61/SHINE hadron spectrometer at the CERN Super Proton Synchrotron. The data show structures which can be attributed mainly to effects of resonance decays, momentum conservation, and quantum statistics. The results are compared with the Epos and UrQMD models.ISSN:1434-6044ISSN:1434-605
NA61/SHINE measurements of anisotropic flow relative to the spectator plane in Pb+Pb collisions at 30A GeV/c
We present an analysis of the anisotropic flow harmonics in Pb+Pb collisions at beam momenta of 30A GeV/c
collected by the NA61/SHINE experiment in the year 2016. Directed and elliptic flow coefficients are measured relative to the spectator plane estimated with the Projectile Spectators Detector (PSD). The flow coefficients are reported as a function of transverse momentum in different classes of collision centrality. The results are compared with a new analysis of the NA49 data for Pb+Pb collisions at 40A GeV using forward calorimeters (VCal and RCal) for event plane estimation
Search for the critical point by the NA61/SHINE experiment
NA61/SHINE is a fixed target experiment operating at CERN SPS. Its main goals are to search for the critical point of stronglyinteractingmatterandtostudytheonsetofdeconfinement. Forthesegoalsascanofthetwodimensionalphase diagram (T-μB) is being performed at the SPS by measurements of hadron production in proton-proton, proton-nucleus and nucleus-nucleus interactions as a function of collision energy. In this paper the status of the search for the critical point of strongly interacting matter by the NA61/SHINE Collaboration is presented including recent results on proton intermittency, strongly intensive fluctuation observables of multiplicity and transverse momentum fluctuations. These measurements are expected to be sensitive to the correlation length and, therefore, have the ability to reveal the existence of the critical point via possible non-monotonic behavior. The new NA61/SHINE results are compared to the model predictions
Hidden strangeness shines in NA61/SHINE
Preliminary results on the ϕ (1020) meson production in inelastic proton-proton collisions measured by the NA61/SHINE experiment at the CERN SPS are presented in these proceedings. The results include the first ever differential pT and y measurements at beam momenta of 40 and 80 GeV and the most ever detailed experimental data at 158GeV. The comparison of p + p to Pb + Pb results shows a non-trivial system size dependence of the widths of the rapidity distributions for ϕ mesons, contrasting with that of other hadrons. The results are furthermore compared to the world data on ϕ meson production, demonstrating the better accuracy achieved by the NA61/SHINE experiment, and to several models. None of the models is found to be able to describe simultaneously the shape of transverse momentum spectra, the shape of rapidity distribution and the total yield
New approach in forensic studies of trace evidences
Przedstawiono możliwości wykorzystania nowoczesnych technik analitycznych ToF-SIMS (time-of-flight secondary ion mass spectrometry) i LA-ICP-ToF-MS (inductively coupled plasma time-of-flight mass spectrometry with laser ablation) w rozwiązywaniu aktualnych problemów z zakresu chemii sądowej. Przedstawiono przykładowe wyniki badań otrzymanych za pomocą metody ToF-SIMS, dotyczących m.in. analizy zanieczyszczeń znajdujących się na odcisku palca, które naturalnie na nim nie występują, natomiast mogą mieć związek z miejscem zdarzenia. Do badanych zanieczyszczeń należały: amfetamina (AF), metylenodioksymetamfetamina (MDMA, ecstasy) oraz cząstki powystrzałowe (GSR). Za pomocą tej techniki dokonano również próby określenia kolejności powstawania podpisów względem siebie. Metodę LA-ICP-ToF-MS zastosowano do bada-nia czarnych tonerów w postaci tabletek oraz wydruków, materiałów pisarskich (past długopisowych), podłoży papierowych, cząstek GSR oraz ludzkich kości. Na podstawie otrzymanych wyników pokazano duże możliwości wykorzystania wymienionych technik w badaniach kryminalistycznych
