Children’s conceptions of coronavirus
No full textThe present study aimed to examine children’s conceptions of coronavirus as denoted in their verbal descriptions and drawings and whether these vary as a function of children’s age and the mode of expression. Data were collected in Greece during spring 2020 and 344 children aged 4 to 10 years were first asked to verbally describe coronavirus and then to produce a drawing of it. Content analysis of data revealed the following main themes: (a) Coronavirus, (b) Medical, (c) Psychological, and (d) Social. Results showed that children from an early age present a remarkable level of understanding of coronavirus and the COVID-19 disease as a multidimensional construct, which can be designated not only through characteristics of the Sars-Cov-2 but also through its medical, social, and psychological consequences on people’s lives. Moreover, children were found to emphasize different aspects of this construct depending on their age and the mode of expression. © The Author(s) 2021

Measurement of D∗±, D± and D±s meson production cross sections in pp collisions at √s= 7 TeV with the ATLAS detector
No full textThe production of D∗±, D± and D±s charmed mesons has been measured with the ATLAS detector in pp collisions at √s= 7 TeV at the LHC, using data corresponding to an integrated luminosity of 280 nb−1. The charmed mesons have been reconstructed in the range of transverse momentum 3.5 <pT(D) <100 GeV and pseudorapidity |η(D)| <2.1. The differential cross sections as a function of transverse momentum and pseudorapidity were measured for D∗± and D± production. The next-to-leading-order QCD predictions are consistent with the data in the visible kinematic region within the large theoretical uncertainties. Using the visible D cross sections and an extrapolation to the full kinematic phase space, the strangeness-suppression factor in charm fragmentation, the fraction of charged non-strange D mesons produced in a vector state, and the total cross section of charm production at √s= 7 TeV were derived
Measurement of inclusive and dijet D ∗ meson cross sections in photoproduction at HERA
No full textThe inclusive photoproduction of D * mesons and of D *-tagged dijets is investigated with the H1 detector at the ep collider HERA. The kinematic region covers small photon virtualities Q 21. 8 GeV. The heavy quark production process is further investigated in events with at least two jets with transverse momentum p T(jet)>3. 5 GeV each, one containing the D * meson. Differential cross sections for D *-tagged dijet production and for correlations between the jets are measured in the range {pipe}η(D *){pipe}<1. 5 and p T(D *)<2. 1 GeV. The results are compared with predictions from Monte Carlo simulations and next-to-leading order perturbative QCD calculations. © 2012 The Author(s).0SCOPUS: ar.jinfo:eu-repo/semantics/publishe
Measurement of |V(cb)| using the semileptonic decay anti-B/d0 ! D*+1- anti-nu/1.
No full textData from Z decays in DELPHI have been searched for [(B- d(o))over bar] � D<sup>star</sup>+ l(-) (ν) over bar (l) with the D<sup>star</sup>+ decaying to D(0)pi(+) and D-0 � K(-)pi(+), K(-)pi(+)pi(+)pi(- ) or K- pi(+)(pi(0)). These events are used to measure the CKM matrix element \V-cb\ and the form factor slope, rho(A1)(2): F- D<sup>star</sup>(1) \V-cb\ = 0.0392 +/- 0.0018 +/- 0.0023; rho(A1)(2) = 1.32 +/- 0.15 +/- 0.33 corresponding to a branching fraction: BR([(B-d(0))over bar] � D(<sup>star</sup>+)l(-)(ν) over bar (l)) = (5.90 +/- 0.22 +/- 0.50)%. Combining these and previous DELPHI measurements gives: FD<sup>star</sup>(1)\V-cb\ = 0.0377 +/- 0.0011 +/- 0.0019, rho(A1)(2) = 1.39 +/- 0.10 +/- 0.33 and BR([(B- d(0))over bar] � D(<sup>star</sup>+)l(-)(ν) over bar (l)) = (5.39 +/- 0.11 +/- 0.34)% Using F-D<sup>star</sup>(1) = 0.91 +/- 0.04, yields: \V-cb\ = 0.0414 +/- 0.0012(stat.) +/- 0.0021(syst.) +/- 0.0018 (theory). The b-quark semileptonic branching fraction into a D<sup>star</sup>+ emitted from higher mass charmed excited states has also been measured to be: BR(b � D<sup>star</sup>+ Xl(-)(ν) over bar (l)) = (0.67 +/- 0.08 +/- 0.10)%
USING GIS AND EARTHQUAKE SCENARIOS FOR THE ASSESSMENT OF EMERGENCY RESPONSE IN CASE OF A STRONG EARTHQUAKE. AN APPLICATION IN THE URBAN AREA OF THESSALONIKI, GREECE
No full textThe aim of this paper, which is part of the M.Sc Thesis of the first author, is an initial attempt for the assessment of the emergency response through the road network of the Urban Area of Thessaloniki (UAT) after a strong earthquake. The areas of the road network that are to become inaccessible either due to partial collapse of buildings or due to destruction of the road axes by rupture zones, are detected. The inaccessible parts are determined for the cases of three earthquake scenarios using the values of the Peak Ground Acceleration (PGA), which were calculated for about 6000 points over the UAT, as well as spatial overlay tools of a GIS. In the end, by applying network analysis and according to the situation of the network after the earthquake, the possibility of movement of the fire engines and ambulances was studied and least cost routes from ambulance stations to UAT hospitals were tracked

Dispersal versus vicariance in the Aegean: Combining molecular and morphological phylogenies of eastern Mediterranean Dendarus (Coleoptera: Tenebrionidae) sheds new light on the phylogeography of the Aegean area
No full textThe Aegean archipelago, as an 'evolutionary laboratory of nature', is an ideal model for research in phylogeography. In this area, the darkling beetles of the genus Dendarus (distributed from Morocco to the Caucasus) exhibit a high level of diversity with 36 species, 27 of which are island endemics. However, their taxonomy is complex and unstable, having undergone continuous revision to address extensive morphological and ecological plasticity. Here, we examine the phylogenetic relationships of 23 species from Greece and Turkey, using mitochondrial and nuclear DNA sequences and 61 morphological characters, to unveil their phylogeny in the Aegean. This helps to clarify phylogeographic scenarios and historical processes that shaped the observed patterns. The analyses reveal 13 distinct lineages with several para- and polyphyletic cases that correspond to three major phylogroups [south/south-east Aegean (D. foraminosus complex, D. rhodius, D. sporadicus, D. wettsteini); central to north Aegean, Turkey and mainland Greece (D. crenulatus, D. moesiacus group, D. sinuatus complex, D. stygius) and mainland Greece (D. messenius, D. paganettii)], indicating the need for further taxonomic re-evaluation. Lineage topology and phylogeography suggest a spatial and temporal sequence of geographic isolation, following either a vicariant or a dispersal model coincident with major palaeogeographic separations in the Aegean. © 2020 The Linnean Society of London.Seventh Framework Programme, FP7: HU-TAF 1942; University of Crete, UoC; Hungarian Natural History Museum, HNHMWe express our gratitude to Manolis Nikolakakis and Katerina Vardinoyannis (Natural History Museum of Crete, University of Crete) for helping in map drawing, Ljubica Kardaki (Natural History Museum of Crete, University of Crete) for the preparation and assistance with the samples, Nikos Tsirigotakis, Christophoros Pavlou (School of Medicine, University of Crete) and Odysseas Piperagas (Biology Department, University of Crete) for their help with the morphological measurements of the samples and Sandra Siakouli- Galanopoulou (Electron Microscope 'Vassilis Galanopoulos', University of Crete) for assistance with SEM microscopy.
