First evidence of multiple β-delayed neutron emission for isotopes with a > 100
2017
The β-delayed neutron emission probability, Pn, of very neutron-rich nuclei allows us to achieve a better understanding of the nuclear structure above the neutron separation energy, Sn. The emission of neutrons can become the dominant decay process in neutron-rich astrophysical phenomena such as the rapid neutron capture process (r-process). There are around 600 accessible isotopes for which β-delayed one-neutron emission (β1n) is energetically allowed, but the branching ratio has only been determined for about one third of them. β1n decays have been experimentally measured up to the mass A ∼ 150, plus a single measurement of 210Tl. Concerning two-neutron emitters (β2n), ∼ 300 isotopes are …
High-sensitivity study of levels in 30Al following β decay of 30Mg
2016
γ -ray and fast-timing spectroscopy were used to study levels in 30Al populated following the β− decay of 30Mg. Five new transitions and three new levels were located in 30Al. A search was made to identify the third 1+ state expected at an excitation energy of ∼2.5 MeV. Two new levels were found, at 3163.9 and 3362.5 keV, that are firm candidates for this state. Using the advanced time-delayed (ATD) βγγ (t) method we have measured the lifetime of the 243.8-keV state to be T1/2 = 15(4) ps, which implies that the 243.8-keV transition is mainly of M1 character. Its fast B(M1; 2+ → 3+) value of 0.10(3) W.u. is in very good agreement with the USD shell-model prediction of 0.090 W.u. The 1801.5-k…

Revision of New World Species of the Shore-fly Subgenus Allotrichoma Becker of the Genus Allotrichoma with Description of the Subgenus Neotrichoma (D…
2012
The New World species of the subgenera Allotrichoma Becker and Neotrichoma (new subgenus) are revised, including a phylogenetic analysis of the species groups and subgenera within the genus Allotrichoma. For phylogenetic perspective and to document the monophyly of the genus Allotrichoma and its included subgenera and species groups, we also provide a cladistic analysis of genera within the tribe Hecamedini. The ingroup included seven exemplar congeners from within Allotrichoma. Outgroup sampling included exemplars of other genera within Hecamedini and from the putative sister group, Lipochaetini, and to root the analysis, we used an exemplar of the tribe Discocerinini. Analyses with succes…

Validity and reliability of the checklist of non-verbal pain indicators in Albanian. First step
2018
Background: in Albania non ci sono strumenti affidabili per valutare la presenza di dolore nei pazienti non-verbalizzanti. L'obiettivo del nostro studio era di fornire una validazione linguistica della checklist in albanese per gli indicatori di dolore non verbale (CNPI). Metodi: dopo la traduzione inversa, abbiamo usato la versione albanese in uno studio trasversale per verificare sia l'affidabilità che la validità di questo strumento in contesti clinici. La Visual Analog Scale è stata adottata come gold standard. Sono stati usati anche il kappa di Cohen e il coefficiente di correlazione di Pearson. La validità costruttiva del CNPI è stata stabilita mediante l'analisi fattoriale esplorativ…
Triage protocol for allocation of critical health resources during the COVID-19 health emergency. A review
2020
Background and aim of the work:Triage during the Covid-19 pandemic can impose difficult allocation deci-sions when demand for mechanical ventilation or intensive care beds greatly exceeds available resources. Tri-age criteria should be objective, ethical, transparent, applied equitably and publically disclosed. The aim of this review is to describe the triage tools and process for critical care resources in a pandemic health emergency. Methods:A narrative review was conducted of the literature on five electronic databases, namely PubMed, CINHAL, Web of Science, Cochrane and Embase, searching for studies published from 2006 to June 2020. Results:The results describe different triage tools. A…
The Misdirection as Anxiety Reduction in Children from Venipuncture Procedure: A Randomized Study
2020
The current literature show several distraction approaches to reduce anxiety in children during the painful procedure, as the venipuncture. This work explored the magician intervention effects in anxiety and in pain reduction among children who underwent the venipuncture procedure. Our results showed that the magician approach among nurses could effectively influence the children compliance who underwent a venipuncture without any particular cost for the healthcare system.
Relationship between cladoceran (Crustacea) functional diversity and lake trophic gradients
2017
Functional diversity (FD) as a biodiversity measure has an explicit role in ecosystem functioning because the effects of environmental changes in ecosystems are determined by biological functions, such as feeding type and trophic position, of particular species. We evaluated the usability of functional characterization and FD of an aquatic keystone group (Crustacea: Cladocera) for enhancing the understanding of long-term lake functional responses to environmental changes. The aims were to separate ecologically significant functional groups, investigate succession of such functional groups during nutrient enrichment process and determine the relationship between FD and lake productivity usin…
