The Gaia-ESO Survey: membership and initial mass function of the. Velorum cluster
2016
Understanding the properties of young open clusters, such as the Initial Mass Function (IMF), star formation history and dynamic evolution, is crucial to obtain reliable theoretical predictions of the mechanisms involved in the star formation process. We want to obtain a list, as complete as possible, of confirmed members of the young open cluster Gamma Velorum, with the aim of deriving general cluster properties such as the IMF. We used all available spectroscopic membership indicators within the Gaia-ESO public archive together with literature photometry and X-ray data and, for each method, we derived the most complete list of candidate cluster members. Then, we considered photometry, gra…
One‐Pot Synthesis of a New High‐Aluminium‐Content Super‐Microporous Aluminosilicate
2006
A new super-microporous aluminosilicate having a high aluminium content (Si/Al ca. 1) has been prepared through a surfactant-assisted procedure with the use of a commercially available binary precursor (di-sec-butoxyaluminooxytriethoxysilane) as a single source of both Al and Si. The formation of super-micropores is a result of a significant network shrinkage associated with the thermal elimination of the surfactant. This solid has been studied by X-ray powder diffraction, electron microscopy, nuclear magnetic resonance spectroscopy and porosimetry. A preliminary analysis of the acidity and the catalytic activity of the super-microporous solid for the selective catalytic reduction of NOx is…
Precision luminosity measurements at LHCb
2014
Measuring cross-sections at the LHC requires the luminosity to be determined accurately at each centre-of-mass energy $\sqrt{s}$. In this paper results are reported from the luminosity calibrations carried out at the LHC interaction point 8 with the LHCb detector for $\sqrt{s}$ = 2.76, 7 and 8 TeV (proton-proton collisions) and for $\sqrt{s_{NN}}$ = 5 TeV (proton-lead collisions). Both the "van der Meer scan" and "beam-gas imaging" luminosity calibration methods were employed. It is observed that the beam density profile cannot always be described by a function that is factorizable in the two transverse coordinates. The introduction of a two-dimensional description of the beams improves sig…
The THESEUS space mission concept: science case, design and expected performances
2018
THESEUS is a space mission concept aimed at exploiting Gamma-Ray Bursts for investigating the early Universe and at providing a substantial advancement of multi-messenger and time-domain astrophysics. These goals will be achieved through a unique combination of instruments allowing GRB and X-ray transient detection over a broad field of view (more than 1sr) with 0.5¿1 arcmin localization, an energy band extending from several MeV down to 0.3¿keV and high sensitivity to transient sources in the soft X-ray domain, as well as on-board prompt (few minutes) follow-up with a 0.7¿m class IR telescope with both imaging and spectroscopic capabilities. THESEUS will be perfectly suited for addressing …

Prospects for quarkonium studies at the high-luminosity LHC
2020
Prospects for quarkonium-production studies accessible during the upcoming high-luminosity phases of the CERN Large Hadron Collider operation after 2021 are reviewed. Current experimental and theoretical open issues in the field are assessed together with the potential for future studies in quarkonium-related physics. This will be possible through the exploitation of the huge data samples to be collected in proton-proton, proton-nucleus and nucleus-nucleus collisions, both in the collider and fixed-target modes. Such investigations include, among others, those of: (i) J/psi and Upsilon produced in association with other hard particles; (ii) chi(c,b) and eta(c,b) down to small transverse mom…
Differential branching fraction and angular analysis of the decay $B^{0} \to K^{*0} \mu^{+}\mu^{-}$
2013
The angular distribution and differential branching fraction of the decay B-0 -> K*(0)mu(+)mu(-) are studied using a data sample, collected by the LHCb experiment in pp collisions at root s = 7 TeV, corresponding to an integrated luminosity of 1.0 fb(-1). Several angular observables are measured in bins of the dimuon invariant mass squared, q(2). A first measurement of the zero-crossing point of the forward-backward asymmetry of the dimuon system is also presented. The zero-crossing point is measured to be q(0)(2) = 4.9 +/- 0.9 GeV2/c(4), where the uncertainty is the sum of statistical and systematic uncertainties. The results are consistent with the Standard Model predictions.
Proteīnus saturošu uztura bagātinātāju un medicīniskās pārtikas produktu klāsta un sastāva izvērtējums Latvijas aptiekās
2022
Mūsdienās uztura bagātinātāji un specializētā pārtika ar paaugstinātu proteīnu daudzumu ir aktuālas sakarā ar pacientiem, kas nespēj uzņemt parasto uzturu (onkoloģijas pacienti, pēcoperāciju stāvokļi, geriatrija utt.), kā arī ir aktuāla veciem, mazkustīgiem cilvēkiem, piem., saslimšanas gadījumā, kad proteīnus saturoši uztura bagātinātāji tiek izmantoti kā papildinājums ikdienas uzturam. Paaugstināts proteīnu uzņemšanas daudzums ir ļoti svarīgs profesionāliem sportistiem vai cilvēkiem ar paaugstinātu fizisko slodzi. Iegūtie rezultāti liecina, ka no pētāmās enterālās barošanas pārtikas, vislielākais proteīnu daudzums bija pulverveida produktos, bet, savukārt, vitamīnu, mikroelementu un …
Experimental investigations of the hypernucleus $_Λ^4$H
2015
International audience; Negatively charged pions from two-body decays of stopped _Lambda^4H hypernuclei were studied in 2012 at the Mainz Microtron MAMI, Germany. The momenta of the decay-pions were measured with unprecedented precision by using high-resolution magnetic spectrometers. A challenge of the experiment was the tagging of kaons from associated K^+∧ production off a Be target at very forward angles. In the year 2014, this experiment was continued with a better control of the systematic uncertainties, with better suppression of coincident and random background, improved particle identification, and with higher luminosities. Another key point of the progress was the improvemen…
Nota a Cass. 12 dicembre 2019, n. 50340, S., in materia di lancio di materiale pericoloso in occasione di manifestazioni sportive, concorso morale e …
2020
La sentenza in epigrafe si segnala all'attenzione per aver precisato i criteri che consentono di distinguere le fattispecie di attentato alla sicurezza pubblica di cui all'art. 6 l. n. 895 del 1967, così come novellata dall'art. 13 l. n. 497 del 1974, e quella di «lancio di materiale pericoloso, scavalcamento ed invasione di campo in occasione di manifestazioni sportive», disciplinata dall'art. 6 bis l. n. 401 del 1989. Con essa, inoltre, la Suprema Corte torna a fare il punto, rispettivamente, sul tema del concorso morale e sui presupposti della continuazione.
