Agriculture and Sustainability: a GIS Based Model to Appraise Incentive Policy
Agriculture is the major form of protection of local identities and sustainability and one of the most fragile Italian economic sectors, exposed to fluctuations of the financial/economic crisis. As a consequence, boosting agricultural policies should integrate conflicting objectives connected to preservation and innovation, effectiveness/efficiency, and landscape features and job opportunities. Referring to a large land area located in the central part of Sicily (Italy) the paper proposes an assessment/planning pattern aimed at providing some axiological items and a specific algorithm able to appraise each specific land parcel, generating different strategies and selecting the best format o…
A practical and transferable methodology for dose estimation in irradiated spices, based on thermoluminescence dosimetry
Abstract The thermoluminescence technique is recommended by the European Committee for Standardization for the detection of irradiated food containing silicates as contaminants. In this work, the applicability of the thermoluminescence technique as a quantitative method to assess the original dose in irradiated oregano was studied; the additive-dose method was used, with reirradiation doses up to 600 Gy. The proposed new procedure allows to clearly discriminate irradiated from unirradiated samples, even after one year storage, and it gives an acceptable estimation of the original dose; the overall modified procedure requires only one day to be completed.
The additive dose method for dose estimation in irradiated oregano by thermoluminescence technique
The ionizing radiation treatment of food is nowadays a worldwide recognized tool for food preservation, provided that proper and validated identification methods are available and used. The thermoluminescence (TL) technique is one of the physical methods recommended by the European Committee for Standardization to distinguish irradiated from not irradiated samples, for food containing silicate minerals as contaminants, such as spices and aromatic herbs, which are among the most frequently irradiated foods. The experimental results presented in this work show that, at least up to the highest tested doses (2 kGy), it is possible to set up a procedure to estimate the actual dose in the irradia…
The Urban Landscape and the Real Estate Market. Structures and Fragments of the Axiological Tessitura in a Wide Urban Area of Palermo
The proposed study deals with the urban landscape of Palermo and its possible representation from the perspective of the real estate market analysis. Real estate is one of the most significant types of capital asset and the wide range of its possible utilizations makes complex the interpretation of the market phenomena. The multi-layered reality of such a large city (represented through the sample of 500 properties) needs to be articulated into a significant set of sub-markets in order to outline the complexity and to map the distribution of homogeneous groups of properties within the whole city area. The comparison between quality and price within each cluster allows us to elicit the degre…
The gas chromatography/mass spectrometry can be used for dose estimation in irradiated pork
Abstract Food safety can be improved using ionizing radiation to reduce food spoilage and to extend its shelf life. The gas chromatography/mass spectrometry (GC/MS) has been validated by the European Community as a powerful method to identify irradiated food containing fat. The preliminary goals of our research were: (i) to set up this method, based on the detection of radiation induced 2-dodecylcyclobutanones (2-DCB) in pork muscle samples and (ii) to check the microbiological efficacy of the treatment. The main objective was to render the GC/MS a quantitative technique for dose estimation, through the measurement of the 2-DCB concentration in the irradiated sample. Our results show that t…
Proteins in Saccharides Matrices and the Trehalose Peculiarity: Biochemical and Biophysical Properties
Immobilization of proteins and other biomolecules in saccharide matrices leads to a series of peculiar properties that are relevant from the point of view of both biochemistry and biophysics, and have important implications on related fields such as food industry, pharmaceutics, and medicine. In the last years, the properties of biomolecules embedded into glassy matrices and/or highly concentrated solutions of saccharides have been thoroughly investigated, at the molecular level, through in vivo, in vitro, and in silico studies. These systems show an outstanding ability to protect biostructures against stress conditions; various mechanisms appear to be at the basis of such bioprotection, th…

Impact of universal vaccination against varicella in Italy: Experiences from eight Italian Regions.
In Italy, the introduction of Universal Varicella Vaccination (UVV) has been decided but postponed, as a national programme, until 2015, when data from Regions which have already implemented it will be available. Starting from 2003, eight Italian Regions (Basilicata, Calabria, Friuli Venezia Giulia, Apulia, Sardinia, Sicily, Tuscany and Veneto) have progressively introduced UVV, in their immunization programme, with different schedules in children aged 13-15 months and 5-6 years, currently a two-dose schedule is adopted by all Regions. In June 2013, an Interregional Group on Varicella Vaccination (IGVV) has been established in order to assess the effectiveness of varicella vaccination with …
Application of the ESR spectrometry to evaluate the original dose in irradiated dried fruit
The identification of irradiated dried fruit can be achieved by means of the electron spin resonance (ESR) spectrometry, as recommended by the European Community, since ionizing radiation induces free radicals in cellulose, a constituent of the shell. The aim of this work was to use the ESR spectrometry also as a quantitative procedure to evaluate the original dose in irradiated dried fruits, using the additive dose method. Little shell pieces, taken from nuts, chestnuts, peanuts and pistachios, were irradiated at original dose values in the range 1 to 8 kGy, and the ESR signal intensity was measured. Each specimen was then reirradiated with added doses of 1 kGy, and the ESR signal was me…
Gas chromatographic/mass spectrometric and microbiological analyses on irradiated chiken
Ionizing radiation is widely used as treatment technique for food preservation. It involves among others reduction of microbial contamination, disinfestations, sprout inhibition and extension of shelf life of food. However, the commercialization of irradiated food requires the availability of reliable methods to identify irradiated foodstuffs. In this paper, we present results on the application to irradiated chicken of this method, based on the detection, in muscle and skin samples, of the peaks of ions 98 Da and 112 Da, in a ratio approximately 4:1, typical of radiation induced 2-dodecylcyclobutanones (2-DCB). Aim of the work was also to study the time stability of the measured parameters…

Children with special health care needs attending emergency department in Italy: analysis of 3479 cases
Abstract Background Although children with special health care needs (CSHCN) represent a minority of the population, they go through more hospitalizations, more admissions to the Emergency Department (ED), and receive a major number of medical prescriptions, in comparison to general pediatric population. Objectives of the study were to determine the reasons for admission to the ED in Italian CSHCN, and to describe the association between patient’s demographic data, clinical history, and health services requirements. Methods Ad hoc web site was created to collect retrospective data of 3479 visits of CSHCN to the ED in 58 Italian Hospitals. Results Seventy-two percent of patients admitted to …
