Optimizing [13N]N2 radiochemistry for nitrogen-fixation in root nodules of legumes
2010
Here we explored the conditions for synthesizing [ 13 N]N 2 in a state that is suitable for the administration to plant root nodules enabling studies of nitrogen fixation. [ 13 N]N 2 was prepared batchwise, starting with [ 13 N]NO ― 3 from the 16 O(p,α) 13 N nuclear reaction on a liquid water target. [ 13 N]NO ― 3 was first reduced to [ 13 N]NH 3 using Devarda's alloy, and then the [ 13 N]NH 3 was oxidized to [ 13 N]N 2 by hypobromite using carrier-added NH 4 CI. The amounts of carrier NH 4 CI and hypobromite were varied to determine the effects these parameters had on the radiochemical yield, and on the radiotracer specific activity. As expected, increasing the amount of carrier NH 4 CI im…
Analysis of metallic impurity content by means of VUV and SXR diagnostics in hybrid discharges with hot-spots on the JET-ITER-like wall poloidal limi…
2019
In preparation for the upcoming JET D-T campaign, great effort has been devoted during the 2015-2016 JET campaigns with the ITER-like wall (ILW) to the extension of the high performance H-mode phase in baseline and hybrid scenarios. Hybrid discharges were the only ones that have been stopped by the real-time vessel protection system due hot-spot formation on the outboard poloidal limiter. Generation of hot-spots was linked to the application of high neutral beams injection and ion cyclotron resonance heating (ICRH) power. In tokamaks with high-Z plasma components, the use of ICRH heating is also accompanied by an increased metallic impurity content. Simultaneous control of hot-spot temperat…
Efecto de la masoterapia sobre la ictericia neonatal: revisión sistemática
2019
espanolObjetivo: Identificar, evaluar y sintetizar la mayor evidencia disponible sobre el efecto del masaje en la ictericia en neonatos a termino tratados o no con fototerapia. Metodo: Se desarrollo una revision siguiendo la declaracion PRISMA. Para ello se realizouna exhaustiva busqueda sistematica en las bases de datos PubMed, Cuiden, Scopus, Scielo y Cnki de los articulos publicados entre enero del 2009 y junio del 2018. Los estudios seleccionados fueron sometidos a una evaluacion de la calidad metodologica mediante la escala PEDro. Resultados: Un total de 10 trabajos cumplian los criterios inclusion y fueron incorporados a la revision. Estos presentaban una calidad metodologica moderada…

THE VALIDATION OF A SELF-ASSESSMENT TOOL FOR THE TEACHER'S PRACTICES THAT EMBRACES THE NEURO-EDUCATIONAL APPROACH
2021
This contribution intends to present a study and research path that, starting from the theoretical framework of neuro-education, has led to the identification of five indicators (transversal area, socio-emotional-affective area, cognitive area, linguistic-communicative area, praxico-motor) on the basis of which a neuro-evaluation tool for teachers was built and validated: Self-assessment questionnaire of neuro-didactic and educational practices for teachers. Neuroscientific research is offering numerous points of reflection-action on the functioning of the brain and on how to modify the teaching and the educational proposal to improve the performance and growth of the person. However, the p…
Parking Pricing for a Sustainable Transport System
2014
Abstract The purpose of this study has been the develop of a model for designing an efficient parking pricing policy. The aim is an intelligent control and management system of parking pricing integrated with a redefinition of the circulation scheme for a limited traffic zone in the Central Business District (CBD) of Palermo. The transport demand over the entire area of the town has been studied in order to design various parking pricing scenarios with the application of an additional cost on parking inside the selected area of the CBD. This area attracts most of the private vehicular traffic and it is characterized by university faculties, schools, hospitals, offices and commercial areas. …
Studies on Reticulitermes lucifugus Rossi (Isoptera: Rhinotermitidae): a review of associated hindgut flagellates and investigations on protist speci…
2017
The present study was conducted on protist species from R. lucifugus “Sicily” subspecies in a field site of Palermo (Sicily, Italy) on June 2015. Since protist species associated with R. lucifugus in Europe are still confused and recent revisions are lacking, this work aims at achieving greater clarity on these symbiosis trough a review of the literature in light of new phylogenetic studies on this termite species. The purpose of this work was also to highlight and quantify protists associated with the Sicilian subspecies, R. l. “Sicily”. Results pointed out the real protist community attributable to R. lucifugus from the literature and showed 13 protist species detected in the subspecies R…
L’acarofauna utile (Parasitiformes, Phytoseiidae) associata alle specie forestali del sito Natura 2000 “Bosco di S. Adriano”
2008
Within the acarofauna present in ecosystems, the Phytoseiidae family has a relevant role as it includes species considered as the most important biocontrol agents of phytophagous mites. Their specific composition in various habitats is influenced by numerous factors both biotics and abiotics, while the number of species increases if the complexity of the ecosystem increases. In order to know the specific composition of phytoseiid mites in two natural habitats and to check possible changes in a near future, a survey of phytoseiid mites was carried out in a Natura 2000 location S. Adriano woods (Sicily). This research was done within the project ManagMED “Integrated development and management…
PALAZZO STERI DI PALERMO, SOFFITTO LIGNEO DELLA SALA MAGNA INDAGINE FITOSANITARIA
2012
ABSTRACf - Steri Palace of Palermo; Wooden Ceiling of the "Sala Magna ", Phytosanitary Survey. The Steri Palace (from Hosterium = fortified residence) of Palermo was built in the early fourteenth century, exactly from 1307 to 1320, it was Chiaramonte's family residence. Later, it became the seat of the viceroy of Sicily (from 1412 to 1577), of the Director of the Royal "Magna Curia", and Royal Customs (until 1698), of the Inquisition Tribunal (from 1701 to 1792), of the Judicial offices and Custom offices (from 1800 to 1958). Today it is the Centre of the Chancellor's offices of the University of Palermo. It contains several interesting cultural heritage artefacts, including the beautiful d…
