Toward morphological thoracic EIT: major signal sources correspond to respective organ locations in CT.

2012

Lung and cardiovascular monitoring applications of electrical impedance tomography (EIT) require localization of relevant functional structures or organs of interest within the reconstructed images. We describe an algorithm for automatic detection of heart and lung regions in a time series of EIT images. Using EIT reconstruction based on anatomical models, candidate regions are identified in the frequency domain and image-based classification techniques applied. The algorithm was validated on a set of simultaneously recorded EIT and CT data in pigs. In all cases, identified regions in EIT images corresponded to those manually segmented in the matched CT image. Results demonstrate the abilit…

Recovering coronavirus from large volumes of water

2021

The need for monitoring tools to better control the ongoing coronavirus disease (COVID-19) pandemic is extremely urgent and the contamination of water resources by excreted viral particles poses alarming questions to be answered. As a first step to overcome technical limitations in monitoring SARS-CoV-2 along the water cycle, we assessed the analytical performance of a dead end hollow fiber ultrafiltration coupled to different options for secondary concentrations to concentrate viral particles from large volume of spiked tap water, seawater and surface water together with two quantitative RT-qPCR detection kits. Spiking the porcine epidemic diarrhea virus (PEDV), an enveloped virus surrogat…

The importance of wine attributes for purchase decisions: A study of Italian consumers’ perception

2013

"The importance of extrinsic and intrinsic attributes of wine for purchase decisions is the object of a lively debate. As a matter of fact, in recent decades, the shift of consumption motivations from nutritional purposes to drinking for pleasure has caused a persistent decrease in the overall demand. However, the increasing number of product varieties and brands of domestic and imported wine, as well as the increased diversity in wine styles and prices, make the identification of wine purchase drivers difficult. This article investigates the importance of product attributes for Italian consumers when choosing wine. Specifically, a class of statistical models for ordinal data, namely CUB, i…

Geographical cues: evidences from New and Old World countries' wine consumers

2020

PurposeThis systematic review aims to investigate how geographical cues affect wine consumers' behaviors, with reference to the New and Old Worlds, and accordingly, how are recent consumption patterns and new consumer profiles modifying roles of geographical cues?Design/methodology/approachThis work employed a systematic literature review methodology on the extant literature published from 2009 to 2019.FindingsResults, summarized in a conceptual framework, emphasize five thematic areas on how geographical cues should be considered for future research and for new marketing strategies to capture consumers of New and Old World wines. Consumers' wine knowledge, socio-ethno-demographic factors, …

The willingness to pay of Sicilian consumers for a wine obtained with sustainable production method: An estimate through an ordered probit sample-sel…

2019

The growing presence of Sicilian sustainable wine has pushed the research group to investigate and analyse the consumers' behaviour and their potential willingness to pay a premium price for the wine obtained through sustainable production processes. The analysis of the consumer's behaviour towards the wine made with sustainable production methods is carried out in order to provide potentially useful indications to Italian and in particular Sicilian wine enterprises regarding the production and marketing strategies to undertake in a future perspective. This study shows the result of an empirical investigation on the consumption of sustainable wine in Sicily. Through the Ordered (demographic…

2013

Purpose: To describe the consumption of alcoholic beverages in a German wine area, with special attention to the number of people drinking more than the tolerable upper alcohol intake level (TUAL). Methods: A cross-sectional study was conducted using a mailed questionnaire, to investigate the weekly consumption of wine, beer, and spirits during the preceding 12 months in Mainz, the state capital of Rhineland-Palatinate, Germany. The analysis included 948 responders aged 20–69 years. Results: A total of 948 respondents, with a mean age of 43.7 years, were included in the analysis. About 85% of the respondents consumed alcoholic beverages, with an average of about 13.5 g alcohol/day. Men dran…

Wine and Women: A Focus on Feminine Consumption of Wine

2014

Continuous evolution of modern society provides changes in lifestyle and consumption habits, consequently reflecting on food consumption, where we can include the wine. In this context, even for wine there have been changes from the past to today, driving more and more consumers to think about this product less and less as a beverage and an more as a hedonistic and refined product. Relationship with wine changed also at generational and social level and women become interested and passionate consumers, aware of its quality; often also with a great role in the wine world choosing jobs like wine-sellers, producers, sommeliers or oenologist. Wine by the feminine side means the pleasure of enjo…

A influência do método de armazenamento na transparência do cristalino de porco

2019

Este artículo se ha publicado de forma definitiva en: http://www.scielo.br/pdf/abo/v82n1/0004-2749-abo-82-01-0056.pdf Purpose: The porcine eye is frequently used as a research model. This paper analyzes the effect of different storage methods on the transparency of pig crystalline lens. Methods: A spectral transmission curve (from 220 to 780 nm) for the crystalline lens was determined experimentally after storage in different conditions: saline solution, formalin, castor oil, and freezing at -80°C. The total transmission in the visible spectrum, which was used as an index of transparency, was calculated from these curves. For comparative purposes, fresh lenses were evaluated and used as con…

Vertical distribution of crop load and fruit quality within vase- and Y-shaped canopies of 'Elegant Lady' peach

2005

Canopy shape and depth may influence crop uniformity of peach trees at harvest. To test this hypothesis we examined yield distribution and fruit quality changes at different canopy levels of peach trees trained to delayed vase (DV) and perpendicular Y (Y). Trees of both training forms were divided vertically into six or seven 50-cm-deep layers and fruit was harvested at commercial ripening from each layer separately. Regardless of training form, number of fruit and yield per layer were highest in the central part of the canopy, but more evenly distributed among canopy layers in Y trees. In DV trees, fruit weight decreased linearly from top to bottom, whereas it remained constant along the t…

Use of NOAA-AVHRR NDVI data for environmental monitoring and crop forecasting in the Sahel. Preliminary results

1992

Abstract Several studies have shown that the NDVI calculated from NOAA-AVHRR data is related to annual rainfall and primary productivity in Sahelian areas. Such correlations, however, are affected by several environmental factors and have been tested only with data accumulated during rainy seasons, which is not ideal for the prediction of crop yield. In the present study a methodology of NOAA AVHRR data processing is presented which utilizes NDVI computed only in the first part of some rainy seasons and statistically takes into account the geographical variability in land resources and atmospheric conditions. From the first results of the application of the methodology in Niger, its potenti…
