Measurement of dielectron production in central Pb-Pb collisions at √sNN = 2.76 TeV

2019

Published by the American Physical Society under the terms of the Creative Commons Attribution 4.0 International license. Further distribution of this work must maintain attribution to the author(s) and the published article's title, journal citation, and DOI. The first measurement of dielectron (e + e −) production in central (0 – 10 %) Pb – Pb collisions at √sNN=2.76TeV at the LHC is presented. The dielectron invariant-mass spectrum is compared to the expected contributions from hadron decays in the invariant-mass range 0 < mee < 3.5 GeV / c2. The ratio of data and the cocktail of hadronic contributions without vacuum ρ0 is measured in the invariant-mass range 0.15 < mee < 0.7 GeV / c2, w…

Emission of Bromine and Iodine from Mt. Etna volcano

2005

Constraining fluxes of volcanic bromine and iodine to the atmosphere is important given the significant role these species play in ozone depletion. However, very few such measurements have been made hitherto, such that global volcanic fluxes are poorly constrained. Here we extend the data set of volcanic Br and I degassing by reporting the first measurements of bromine and iodine emissions from Mount Etna. These data were obtained using filter packs and contemporaneous ultraviolet spectroscopic SO2 flux measurements, resulting in time-averaged emission rates of 0.7 kt yr(-1) and 0.01 kt yr(-1) for Br and I, respectively, from April to October 2004, from which we estimate global Br and I flu…

Electrochemical sensor for phosphate ions based on laser scriber reduced graphene oxide

2022

This preliminary work shows a new and innovative way to produce laser scribed reduced graphene oxide (LSGO) electrodes using different porous substrates (ranging from paper to plastic and fabric). The obtained electrodes were also tested as electrochemical sensors towards the detection of phosphate ions in water. To obtain the electrodes, a water suspension of GO was filtered on top of substrate (such as Whatman® filter paper) and a complete sensor was obtained from its reduction using a CO2 laser. The electrode is composed of working and counter electrodes made of LSGO and a reference electrode of a Ag/AgCl obtained by using a commercial AgCl conductive paste. Phosphate ions were detected …

Czy "pułapka niskiej dzietności" w województwie opolskim? Perspektywa socjologiczna

2017

Badania społeczne prowadzone w krajach Unii Europejskiej, w tym w Polsce dowodzą, że rośnie popularność i znaczenie alternatywnych form życia rodzinnego i coraz mocniej ujawniają się niekorzystne zmiany demograficzne determinowane niechęcią młodych ludzi do posiadania większej liczby potomstwa lub w ogóle niechęcią do posiadania dzieci. W kraju ta sytuacja dotyczy przede wszystkim Opolszczyzny. Podtrzymuję zatem diagnozę dotyczącą przemian systemu wartości opolskiej młodzieży z 2007 r. i na podstawie wyników badań pilotażowych z 2014 r. formułuję uzupełniającą hipotezę, że być może mamy na Opolszczyźnie do czynienia z „pułapką niskiej dzietności” polegającą na ukształtowaniu nowych wzorców …
