Evaluation of silver-infused polylactide films for inactivation of Salmonella and feline calicivirus in vitro and on fresh-cut vegetables
2012
There is a growing trend to develop packaging materials with an active role in guarantying that the quality and safety characteristics of packaged products will remain or improve from preparation throughout shelf-life. In the present study, 0.001-1.0 wt.% silver ions were satisfactorily incorporated into polylactide (PLA) films by a solvent casting technique. Silver migration from the films was measured by voltamperometry and then correlated with its antimicrobial efficacy against Salmonella enterica and feline calicivirus (FCV), a human norovirus surrogate, by using the Japanese industrial standard (JIS Z 2801). The PLA-silver films showed strong antibacterial and antiviral activity in vit…
A single method for recovery and concentration of enteric viruses and bacteria from fresh-cut vegetables
2011
Fresh-cut vegetables are prone to be contaminated with foodborne pathogens during growth, harvest, transport and further processing and handling. As most of these products are generally eaten raw or mildly treated, there is an increase in the number of outbreaks caused by viruses and bacteria associated with fresh vegetables. Foodborne pathogens are usually present at very low levels and have to be concentrated (i.e. viruses) or enriched (i.e. bacteria) to enhance their detection. With this aim, a rapid concentration method has been developed for the simultaneous recovery of hepatitis A virus (HAV), norovirus (NV), murine norovirus (MNV) as a surrogate for NV, Escherichia coli O157:H7, List…
Essai d'une analyse des rapports entre procédures fiscale et pénale
2016
Resume La possibilite de poursuivre un meme comportement en matiere fiscale et penale parait menacee. En tout etat de cause, des lors que sont mises en concurrence deux voies repressives distinctes pour sanctionner de memes faits, ne convient-il pas de s'assurer que selon que l'on optera pour l'une ou l'autre le mis en cause se trouvera dans une situation equivalente du point de vue des garanties qui lui sont octroyees ? L'article 8 de la DDHC soumet le droit repressif penal et administratif (des lors que la sanction a un caractere de punition) a un socle commun de garanties. En droit substantiel, ces standards font l'objet d'une interpretation variable a raison de la specificite des source…
(-)-Isosteviol as a Versatile Ex-Chiral-Pool Building Block for Organic Chemistry
2013
(–)-Isosteviol is readily available in large quantities by the acidic treatment of a common alternative sweetener. The two functional groups of (–)-isosteviol are presented on the same side of the ent-beyerane scaffold with a mutual C–C distance of about 7 A. Their unique concave arrangement experiences a strong asymmetric environment due to an adjacent methyl group. Consequently, this building block has found several applications in supramolecular chemistry and organocatalysis. These areas and the chemical modification of this scaffold as well as its biological activity are surveyed.
Carbon dynamics of soil organic matter in bulk soil and aggregate fraction during secondary succession in a Mediterranean environment.
2013
Clarifying which factors cause an increase or decrease in soil organic carbon (SOC) after agricultural abandonment requires integration of data on the temporal dynamics of the plant community and SOC. A chronosequence of abandoned vineyards was studied on a volcanic island (Pantelleria, Italy). Vegetation in the abandoned fields was initially dominated by annual and perennial herbs, then by Hyparrhenia hirta (L.) Stapf, and finally by woody communities. As a consequence, the dominant photosynthetic pathway changed from C3 to C4 and then back to C3. Conversion of a plant community dominated by one photosynthetic pathway to another changes the 13C/12C ratio of inputs to SOC. Using the time si…
Competent in Work and Love? Emerging Adults’ Trajectories in Dealing With Work–Partnership Conflicts and Links to Health Functioning
2013
In a 3-year longitudinal study on 989 emerging adults, we assessed self-efficacy in dealing with work–family conflicts and different indices of work and relationships characteristics (e.g., satisfaction, commitment, and stress). In addition, we assessed different indices of health functioning (e.g., sick days, body complaints, internalizing and externalizing symptoms, and well-being). Latent class growth analyses revealed three different trajectories of competence with work-to-partnership conflicts over time that were related to work, romantic relationships, and health. Emerging adults in the high stable group (characterized by high levels of self-efficacy in dealing with conflicts in work…

Let R be a complete discrete valuation ring of mixed characteristic (0, p) with fraction field K. The stable reduction theorem affirms that given a smooth, projective, geometrically connected curve over K, C/K, with genus \geq 2, there exists a unique finite Galois extension M/K minimal for the inclusion relation such that C_{M}:= C x M has stable reduction over M. A such extension is called monodromy extension of C/K and the Galois group Gal(M/K) is called the monodromy group of C/K. In this paper, the authors study stable models of p-cyclic covers of P^1_K. At first, they work with covers of arbitrarily high genus having potential good reduction. In particular, they determine for such cov…
Dal tavolo alla città (e ritorno)
2021
Restaurants transform themselves over time and at the same time they transform their relationship with the city, the practices of food consumption, and convivial rituals of everyday life. We will investigate these phenomena starting from the table, a key element of any restaurant activity. The table has to be considered here as a "political" device, an instrument for the prefiguration and shaping of convivial relations. Our exploration will start from the zero degree of the restaurant, in its most traditional manifestation, and then will be extended to the different forms of food consumption that we can experience today in our cities.
A Perspective on Aging in Rotifers
1980
Most research on aging in rotifers has been performed with populations, not with individuals. As a consequence, the dependent variable in these studies is usually either mean lifespan or rate of survivorship. After a brief consideration of the literature published since the last major review (King, 1969), the results of a series of experiments are presented. Males and females of three genetically distinct clones of Brachionus plicatilis were used for a factorial life table analysis at three different temperatures. The results of these experiments indicate several potential problems in using populations to study the aging process of individuals. These problems derive from the fact that lifes…
A voltammetric e-tongue tool for the emulation of the sensorial analysis and the discrimination of vegetal milks
2018
[EN] The relevance of plant-based food alternatives to dairy products, such as vegetable milks, has been growing in recent decades, and the development of systems capable of classifying and predicting the sensorial profile of such products is interesting. In this context, a methodology to perform the sensorial analysis of vegetable milks (oat, soya, rice, almond and tiger nut), based on 12 parameters, was validated. An electronic tongue based on the combination of eight metals with pulse voltammetry was also tested. The current intensity profiles are characteristic for each non-dairy milk type. Data were processed with qualitative (PCA, dendrogram) and quantitative (PLS) tools. The PCA stat…
