A mass spectrometry approach to dairy science
No full textBovine milk is a source of an array of (un)known (bioactive) compounds from a variety of molecular and chemical classes. Because of a such complex food matrix, accurate and sensitive analytical approaches are needed to identify newly formed molecules (e.g. bioactive milk non-nutrients or xenobiotics), to recognize chemical and enzymatic modifications which known milk components undergo upon processing, storage and in vitro digestion. In this perspective, tailored sample preparation followed by liquid chromatography/high resolution mass spectrometry (LC/HR-MS) represents a powerful analytical tool to solve some scientific issues in dairy sector. In this presentation, some of the current applications of MS in dairy science will be discussed with special regard to characterization of novel functional/(bio)active milk compounds [1], reliable identification of dairy markers (e.g. studying post-translational modifications [2], proteolytic phenomena [3–6], identification of bioactive non-nutrients [7–9]), traceability and confirmation of authenticity [10] of dairy products.

Ricerca e progettazione territoriale per la mitigazione del rischio idraulico: l’indagine storico-geografica ed archeologica
No full textIl contributo presenta il tracciato metodologico che ha guidato la ricerca transdisciplinare di interesse comune intrapresa dall’Università di Verona e dalla Regione del Veneto in occasione della progettazione preliminare delle opere di invaso seguite al Piano delle azioni e degli interventi di mitigazione del rischio idraulico e geologico steso all’indomani dell’alluvione del 2010. L’interpretazione geografica dell’evoluzione del territorio, in particolare dei rapporti uomo-ambiente osservabili nel corso del tempo, in relazione alle regioni fluviali, viene praticata come spazio di un incontro possibile tra modelli previsionali e memoria, normativa e realtà territoriale, fruizione e rispetto delle aree perifluvialiResearch and Land Planning for the Mitigation of Hydraulic Risks: the Historical, Geographical and Archaeological Investigation This paper shows the methodological layout which drove the transdisciplinary investigation jointly performed by The University of Verona and Veneto Regional Administration for the preliminary design of the works to be implemented on the water basin which followed the Plan for hydraulic and geological risk mitigating actions and interventions, set down in the aftermath of the 2010 flood. The geographical interpretation of the evolution of this territory, and especially of the man/environment relationship that can be seen through the years in relation to the river regions, becomes the place for a possible encounter between forecasting models and memory, rules and territory, use and regard for areas around rivers

In the pathogenesis of feline infectious peritonitis (FIP) spread of the coronaviruses (FIPV) through the body is ensured by circulating monocytes. Feline enteric coronaviruses (FeCV) seem to be unable to pass through epithelial cells. If Feline Coronaviruses (FCoV) are found in circulating monocytes this would differentiate the FIPV from the other coronaviruses of the cats. Therefore, we examined 62 cats without FIP-related symptoms, most of which were positive for circulating anti-FCoV antibodies, measured by an indirect fluorescent antibody test (IFA), from 3 different catteries (10, 31 and 21 cats), in which their first cases of FIP were recently diagnosed following exposure to the infection by contact with infected cats. In a small sample of blood from each cat, after the haematological analysis, red blood cells were lysed hypotonically. On the blood leukocytes obtained by cytocentrifugation direct immunofluorescence anti-FCoV (DIF) was performed, and the results were analyzed statistically to calculate the prevalences of the positivity for the catteries and to exclude the influence of pathophysiological and methodological variables. No haematological abnormalities were observed in cats from any of the 3 catteries. The prevalence of the FCoV positivity in blood monocytes was 22%. The age and the sex of the cats, the charachteristics of the blood sample (amount of blood, total and differential number of leukocytes, number of erythrocytes) and of the isolated cell populations (purity and recovery), and the presence of aspecific symptoms (moderate rhinitis, enteritis) were unrelated to positivity, while a risk factor such as contact with other infected catteries was highly significant (P<0.01). All the DIF+ve cats were also IFA+ve for circulating anti-FCoV antibodies: anti-FCoV titers were found also in some of the DIF -ve cats maybe due to a cross-reactivity with FeCV. The detection of FCoV on blood monocytes should be considered an useful tool to complete the clinico-serological diagnosis of FIP. Our results also seem to confirm the possibility of using the DIF test to detect the spread of the FCoV into the monocytes
On-Silicon efficient integrated DRAs for millimeter-wave energy harvesting solutions
No full textThis paper presents the analysis and design of on-Silicon dielectric resonator antennas (DRAs) for energy harvesting applications. The proposed antennas, operating at 24 GHz and excited through a simple microstrip line, are built on a high-resistivity silicon substrate 0.525 mm-thick. The design of cylindrical and rectangular resonators using sapphire as dielectric material is first described, leading to 80% of maximum radiation efficiency and gain equal to 5.15 dBi. Given the increasing attention to system-on-a-chip (SoC) circuits, the second study proposed in this paper aims to a complete integrated solution, describing all-Silicon DRAs, both in cylindrical and rectangular shapes. Very promising performances are obtained in this case, too, from the twofold point of view of compactness and efficiency (75% radiation efficiency and gain equal to 4.72 dBi), if compared to standard solutions on Silicon. As regards the fully-silicon solution, a first hypothesis of rectifier is presented, obtaining a 33% RF-to-dc conversion efficiency at 8 dBm with about 3V as maximum dc-output voltage. As a last step of the proposed study, an investigation on the miniaturization of DRAs operating at millimeter waves is described, exploiting high permittivity materials. In particular, a dielectric resonator antenna with εr = 50 is studied

Dual-Purpose Metasurface for Background Insensitive UWB Tag : (Invited Paper)
No full textA circularly polarised metasurface is proposed in this paper. The design of the surface aims at improving the performance of a hybrid radiating structure made of one dipole and an Archimedean spiral antenna designed on the same surface. The antennas operate in UHF and lower European UWB bands, respectively, and realize a compact single-port antenna for future generation autonomous RFID tags. A High Impedance Surface (HIS) is employed as the ground plane to serve as a Perfect Magnetic Conductor (PMC), with the double purpose to maintain both the circular polarization in the UWB band and the low-profile stack-up, while assuring an insensitive behaviour to the background material
