Nature in malls: Effects of a natural environment on the cognitive image, emotional response, and behaviors of visitors
2019
This study aims to assess the role of a natural environment and its effects on the following components of attitudes: cognitive image, affective response, and behavioral intentions. Using a survey conducted among 292 mall visitors, this study also examines how the perception of the atmosphere in a mall can indirectly affect behavioral intentions. The findings confirm that the components of cognitive image, namely, appealingly design features, may positively influence affective responses at malls. Affective response also positively impacts the behavioral intention of a mall visitor. Affective response features were found to be more powerful than the cognitive image and natural atmosphere att…
Monitoring the Shelf-Life of Minimally Processed Fresh-Cut Apple Slices By Physical Chemical Analysis and Electronic Nose
2014
Fresh-cut apples, in slices or in cubes, are minimally processed products, which are currently collecting a great interest by fruit marketers for their promising diffusion. Their shelf life, from a microbiological point of view, has been fixed about 2 or 3 weeks under refrigeration. However in a few days they undergo biochemical degradations with production of off-flavors and texture breakdown. In this work, the change of aromatic fingerprint of apple slices packaged in air and in a modified atmosphere (with 100% N2) and stored at 4°C was measured, by using a commercial electronic nose. The obtained data were also compared with sensory evaluation of judge’s panel. Moreover, quality paramete…
Risk Assessment of a compound feed process based on HAZOP analysis and linguistic terms
2016
[EN] The size and complexity of industrial plants, along with the characteristics of the products used, require a study, analysis and control of the existing risks in every industrial process. In this paper, a methodology for risk assessment in industrial plants, based on the combination of risks identification through the Hazard and Operability (HAZOP) analysis and the risks evaluation through linguistic variables and fuzzy numbers is applied to a case study consisting on a compound feed plant located in the town of Silla (Valencia, Spain). The results from this study show that the main risk in the compound feed production process is the formation of explosive atmospheres (ATEX). Therefore…
Food: Ordinary Practice or Extraordinary Experience?
2021
Food and the practice of cooking hold a privileged place in contemporary aesthetics, as attested by the extensive literature that has been devoted to this topic. Food has been addressed in both Anglo-American and European studies from multiple points of view, including a cognitivist, pragmatist, phenomenological, everyday and somaesthetic perspective. In this essay I will try to identify a path that allows us to hold together these readings through the ordinary-extraordinary dichotomy. First, I shall analyze food through the lens of the extraordinary, taking into consideration some examples in which food is presented as a true work of art in museums or as an exceptional experience in increa…
Correcting the effect of stellar spots on ARIEL transmission spectra
2020
The goal of this study is to assess the impact of the stellar spots on the extraction of the planetary transmission spectra observed by ARIEL. We develop a method to model the stellar spectrum of a star in the presence of spots by using the out-of-transit observations. It is based on a chi squared minimization procedure of the out-of-transit spectrum on a grid of stellar spectra with different sizes and temperatures of the spots. The approach allows us also to study the temporal evolution of the spots when comparing stellar spectra observed at different epochs. We also present a method to correct the transit depth variations due to non-occulted stellar spots and estimate the error we introd…
Using the transit of Venus to probe the upper planetary atmosphere
2015
The atmosphere of a transiting planet shields the stellar radiation providing us with a powerful method to estimate its size and density. In particular, because of their high ionization energy, atoms with high atomic number (Z) absorb short-wavelength radiation in the upper atmosphere, undetectable with observations in visible light. One implication is that the planet should appear larger during a primary transit observed in high energy bands than in the optical band. The last Venus transit in 2012 offered a unique opportunity to study this effect. The transit has been monitored by solar space observations from Hinode and Solar Dynamics Observatory (SDO). We measure the radius of Venus duri…
Contro il dominio dell’Arte. L’estetica quotidiana dei Futuristi
2020
Uno degli aspetti più significativi del Futurismo è la violenta ribellione contro l’arte aulica del passato. Tale polemica si traduce nella proclamazione di una nuova estetica incentrata sul corpo in movimento e sulle sue relazioni polisensoriali con l’ambiente circostante. Per mettere a fuoco questa prospettiva estetica si prenderanno in considerazione le cosiddette “ambientazioni futuriste”. Esse segnano il momento cruciale in cui la creatività futurista si allarga dall’arte allo spazio quotidiano sia pubblico sia privato, sia domestico sia urbano. Inoltre le ambientazioni attestano il ruolo pionieristico che i futuristi hanno avuto nell’ avviare una riflessione sullo spazio vissuto che m…
ANTIOXIDANT COMPOUNDS AND QUALITATIVE TRAITS IN EUROPEAN (PRUNUS DOMESTICA L.) AND JAPANESE (P. TRIFLORA L.) PLUM FRUITS AS AFFECTED BY COLD STORAGE
2010
The Italian territory is rich in fruit trees germplasm and in the last years many research programs have been carried out to characterize local cultivars and accessions for deepenings about them and enhancing the market agreement too. The Sicilian plum cultivars 'Sanacore' and 'Ariddo di core' and the Piedmontese plum cultivar 'Ramassin' were studied to highlight their qualitative traits including the nutraceutical properties. Moreover, since it is important to know in which way the qualitative parameters change during the storage period one more study was carried out by storing the fruits under modified atmosphere in the Tectrol ® system. The results evidenced very interesting aspects abou…
Assessing the relationship between microwave vegetation optical depth and gross primary production
2018
At the global scale, the uptake of atmospheric carbon dioxide by terrestrial ecosystems through photosynthesis is commonly estimated through vegetation indices or biophysical properties derived from optical remote sensing data. Microwave observations of vegetated areas are sensitive to different components of the vegetation layer than observations in the optical domain and may therefore provide complementary information on the vegetation state, which may be used in the estimation of Gross Primary Production (GPP). However, the relation between GPP and Vegetation Optical Depth (VOD), a biophysical quantity derived from microwave observations, is not yet known. This study aims to explore the …
Effects of Argon-Based and Nitrogen-Based Modified Atmosphere Packaging Technology on the Quality of Pomegranate (Punica granatum L. cv. Wonderful) A…
2021
Ready-to-eat pomegranate arils are considered a “functional food” for their health benefits and have desirable sensory characteristics, which have caused an increasing interest by the consumers for this product. The preparation process of ready-to-eat fruit products can cause severe injuries and worsen their quality and shelf life significantly. Modified atmosphere packaging (MAP) has been used broadly in the last years to maintain the quality of processed fruits and showed optimal results, in spite of the possible problems caused by the depletion of O2 and corresponding accumulation of CO2 in the package. This study was conducted to evaluate the effects of different MAP treatments, based o…
