IMPROVING FOOD QUALITY FOR THE ORGANIC POULTRY MEAT SECTOR: A QUALITY FUNCTION DEPLOYMENT APPROACH

The paper presents results from an Italian study on the development of the food quality for poultry meat into the organic sector, using the Quality Function Deployment (QFD) technique. Results show that among the visual characteristics of poultry meat consumers assign greater importance to attributes strictly related to the animal welfare issue. Price and product appearance (colour and fat presence) come as second. To meet these needs, producers can effectively operate along the supply chain by acting on: housing type, genotype lines and stocking density (animal concentration/mq). Information about these issues (labelling) should also be provided to the consumers

Quality function deployment in the organic animal food sector: application to poultry meat

none3This study presents the results of an Italian investigation into the development of food quality for poultry meat in the organic sector, using the quality function deployment technique. The results show that among the characteristics of poultry, meat consumers assign greater importance to those that are strictly related to animal welfare issues. Price and product appearance (i.e., colour, presence of fat) come in second. To meet these needs, producers can effectively operate along the supply chain by acting on poultry housing type, genotype lines, and stocking density. Information about these issues should then be shared with the consumers (i.e., clear product labelling).Naspetti, Simona; Alberti, Francesca; Solfanelli, FrancescoNaspetti, Simona; Alberti, Francesca; Solfanelli, Francesc

La PET/TC con [18F]Fluorocolina nella valutazione del paziente con carcinoma prostatico

Nella maggior parte dei Registri Tumori si rileva un aumento dell'incidenza del carcinoma prostatico che attualmente nei paesi Occidentali rappresenta il tumore più frequente nel sesso maschile. In Italia il tumore della prostata è la neoplasia più frequente costituendo il 20% di tutti i tumori diagnosticati a partire dai 50 anni. La storia naturale del carcinoma prostatico è altamente imprevedibile: solo in una parte dei pazienti si sviluppa un carcinoma clinicamente manifesto e aggressivo, fortunatamente nella maggior parte dei pazienti il tumore rimane silente. Importante problematica in questi pazienti è la comparsa della recidiva biochimica che viene definita: - dopo PR come un innalzamento del PSA > 0,2 ng/mL in due determinazioni consecutive - dopo RT la presenza di un PSA superiore di 2 ng/mL rispetto al nadir post-RT (criterio di Houston) La PET/TC con [11C]colina ha dimostrato un importante ruolo nell’identificare la sede di ripresa della malattia nel paziente sottoposto a trattamento radicale per tumore prostatico che presenta un progressivo aumento del PSA

Unitarization and Inversion Formulae for the Radon Transform Between Dual Pairs

We consider the Radon transform associated to dual pairs (X,\u39e) in the sense of Helgason, with X = G/K and \u39e = G/H, where G is a locally compact group and K and H are closed subgroups of G. Under some technical assumptions, we prove that if the quasi-regular representations of G acting on L2(X) and L2(\u39e) are irreducible, then the Radon transform admits a unitarization intertwining the two representations. If, in addition, the representations are square- integrable, we provide an inversion formula for the Radon transform based on the voice transform associated to these representations

Application of the new electroanalytical technique AGNES for the determination of free Zn concentration in river water

Absence of gradients and Nernstian equilibrium stripping (AGNES) is a recently developed electroanalytical technique specifically designed for the direct determination of free concentrations of metal ions. AGNES is applied here to the determination of free Zn concentration in a river water sample. The method has been validated with synthetic solutions of low ionic strengths containing Zn and 2,6-pyridinedicarboxylic acid and then applied to synthetic river waters and to a natural sample collected from Besòs River in Montcada i Reixac (Catalonia, North-Eastern Spain). In the river sample, an average free Zn concentration of 12.8(4) nM was obtained, while the total dissolved Zn concentration was 0.51(8) μM. To control and maintain pH and pCO2 constant during AGNES measurements, a novel device for N2/CO2 mixed purging has been developed

Scale-Dependent Turbulent Dynamics and Phase-Space Behavior of the Stable Atmospheric Boundary Layer

The structure of turbulent dynamics in a stable atmospheric boundary layer was studied by means of a phase-space description. Data from the CASES-99 experiment, decomposed in local modes (with increasing time scale) using empirical mode decomposition, were analyzed in order to extract the proper time lag and the embedding dimension of the phase-space manifold, and subsequently to estimate their scale-dependent correlation dimension. Results show that the dynamics are low-dimensional and anisotropic for a large scale, where the flow is dominated by the bulk motion. Then, they become progressively more high-dimensional while transiting into the inertial sub-range. Finally, they reach three-dimensionality in the range of scales compatible with the center of the inertial sub-range, where the phase-space-filling turbulent fluctuations dominate the dynamics

Light-curing process for clear aligners’ attachment reproduction: comparison between two nanocomposites cured by the auxiliary of a new tool

BACKGROUND: Attachments’ configuration play an important role during Clear Aligner Treatment (CAT) for aligner retention and control of movements planned. The aims were to compare the macroscopic morphology of attachments reproduced with flowable (FNC) and conventional (CNC) composites and the effects on them of two light-guide tips with different dimensions. METHODS: 4 resin casts derived from the initial scan of the same patient were obtained. 10 vestibular attachments were replaced on both upper and lower arches of each model with CNC (Models A, B) and FNC (Models C, D). Each composite was cured by means of the same LED lamp with both regular light-guide (Models A, B) and push and light tool® (Models C, D). The 80 attachments were qualitative analyzed by means of a digital stereo microscope. Surface roughness and waviness measurements were assessed by contact probe surface profiler (TalySurf CLI 2000; Taylor Hobson, Leicester, United Kingdom). Statistical analysis was performed with independent samples t-tests. Significance was established at the P < 0.05 level. RESULTS: Model A showed lower values of surface roughness (Ra − 1.41 µm, Rt − 3.46 µm) and waviness (Wa − 2.36 µm, Wt − 10.95 µm) when compared with Model C. Significant reduction of waviness (Wa − 3.85 µm, Wt − 4.90 µm) was observed on Model B when compared with Model D. Significant increase of roughness and waviness parameters (Ra 3.88 µm, Rt 21.07, Wa 2.89 µm, Wt 14.74 µm) was found when CNC sample (Model A) was cured with regular light-guide tip. Higher values (Ra 2.33 µm, Rt 24.07 µm, Wa 1.67 µm, Wt 20.79 µm) were observed after regular light-guide tips curing on FNC sample (Model C). CONCLUSIONS: CNC resins determine more regular surfaces of attachments profiles. The additional use of a smaller light- guide of the LED push and light tool® allows to improve the macroscopic morphology of the attachments and to maximize light irradiance delivering by enhancing the polymerization process and the integrity of the features during the treatment
