Time-like Proton Form Factors with Initial State Radiation Technique

2022

Electromagnetic form factors are fundamental quantities describing the internal structure of hadrons. They can be measured with scattering processes in the space-like region and annihilation processes in the time-like region. The two regions are connected by crossing symmetry. The measurements of the proton electromagnetic form factors in the time-like region using the initial state radiation technique are reviewed. Recent experimental studies have shown that initial state radiation processes at high luminosity electron-positron colliders can be effectively used to probe the electromagnetic structure of hadrons. The BABAR experiment at the B-factory PEP-II in Stanford and the BESIII experim…

Les discours de Libanios (discours 33-64) et la topographie d’Antioche

2012

The work is preparatory to elaborating a Libanius' lexicon attentive to the different nuances that seemingly common words can take on in a specific context such as that of his speech.

I.2 L’area Nord-Occidentale, in Carra et alii, Le aree funerarie fra isola e terraferma: esempi dalla Sicilia e dalla Sardegna, pp. 135-179

2015

Christian funerary evidence of Sicily and Sardinia are among the 3rd-4th century and 7th-8th. They were defined “useful fossils” to determine the incidence of the new religion in urban areas and the importance of the settlement spread over vast areas. The burial areas recognized in Sardinia are about one hundred; in Sicily they are more and more numerous; they are distributed along the route of the ancient roads and fall within the areas of competence of the diocese known by some letters of Pope Gregory the Great. They were divided into three categories: burial areas sub divo, rural and urban; burial underground areas, urban and rural; burial areas connected with a rural church or with a ma…

LEAVES OFNERIUM OLEANDERL. AS BIOACCUMULATORS OF POLYCYCLIC AROMATIC HYDROCARBONS (PAH) IN THE AIR OF PALERMO (ITALY): EXTRACTION AND GC-MS ANALYSIS,…

2005

Polycyclic Aromatic Hydrocarbons (PAH) were determined in the leaves of Nerium oleander L. an evergreen plant that occurs widely in both urban and rural areas, to monitor the degree of pollution in the urban area of Palermo (Italy) compared to remote areas. Twenty sites (urban roadside, urban, urban park, suburban and rural) in and around Palermo city were investigated. The purpose of this research was to investigate concentration levels and distribution patterns and relate them to possible sources. Analysis of 19 PAH was performed by gas chromatography/mass spectrometry (GCMS) using selected ion monitoring (SIM). The total amount of PAH ranged from 10 to 166 μg/Kg d.w. Each source gives ri…

The Need to Approach the Management of the Tourist Destination by the Central and Local Public Authorities in Romania

2017

Abstract In the medium and long term, priorities in the development of tourism aim to develop a complex tourist offer, making the most of the natural and anthropogenic resources existing in connection with the preservation of the environment and the heritage. On the long run, it will contribute to raising the living standards of the population, especially social categories with lower chances of reintegration into the labour market (people made redundant in industry, elderly people etc.). Implementation of the strategy at regional level must be achieved through an active partnership between Romanian public authorities, economic agents and private investors, with the involvement of the federa…

The Ti-influence on the tourmaline color

2008

Titanium was examined in different black tourmalines by spectrophotometric analyses in the region between 12500 and 27000 cm-1 (800-370 nm) using a microscope spectrophotometer MPV-5P, Leitz (Germany), and chemically analyzed on an electron microprobe Camebax Microbeam, Cameca (France) in WDS Mode. Fourteen tourmaline samples with their face oriented parallel to the principal axis, cut and polished down to thin sections, showed polarized spectra of two broad absorption bands at approximately 14000 cm-1 (715 nm) and 24000 cm-1 (417 nm). Precision thickness measurements were used to calculate the absorption coefficients α. For the absorption around 24000 cm-1, a linear correlation was observe…

Evaluación de la presencia de micotoxinas en alimentos y piensos y su mitigación culinaria

2017

En la presente Tesis Doctoral se han desarrollado y validado diferentes procedimientos analíticos para determinar la presencia de micotoxinas clásicas y emergentes en alimentos de origen vegetal y animal. La metodología empleada varía según la matriz y las micotoxinas a determinar y ha sido validada de acuerdo a la normativa europea con resultados satisfactorios en cuanto a linealidad, exactitud, precisión y límites de detección y cuantificación. Por lo que respecta a la presencia de micotoxinas en alimentos de origen vegetal, destacan los elevados contenidos de eniatinas y beauvericina detectados en frutos secos y frutas desecadas. En las materias primas empleadas en la elaboración de pien…
