Fresh-cut products from cactus species
2005
Various species of Cactaceae family can serve a source of delicious and healthy fresh foodstuffs. Marketing cacti as ready-to-eat (fresh-cut) products may significantly expand their consumption, on condition that their quality, safety and longevity would answer the market demands. The present work was aimed at studying the storability of fresh-cut products prepared from several edible cactus species and looking for ways to improve their keeping quality. The experiments included fruit of cactus pear Opuntia ficus-indica (L.) Miller, cactus apple (koubo) Cereus peruvianus (L.) Miller, and dragon fruit (pitaya) Hylocereus undatus (Haw.) Britton and Rose, as well as cladodes (pads) of nopal (ve…
Reference tracking control of hypersonic vehicles using switched linear parameter-varying approach
2013
This paper is concerned with the control problem of the air-breathing hypersonic vehicle using switched linear parameter-varying (LPV) systems approach. By linearizing the nonlinear model of the hypersonic vehicle at trim points and dividing the velocity scope into several partitions, a switched LPV model for the underlying systems is derived. With aid of multiple Lyapunov-like functions technique, the controllers ensuring the tracking of given commands of the closed-loop system are designed under the mode-independent and mode-dependent switching logics, respectively. Simulation results for the hypersonic vehicle show the effectiveness of the proposed method and the advantages of the mode-d…
Espungere e interpretare: a proposito dell’esodo di Ifigenia in Aulide
2014
L’articolo mostra che l’espunzione dell’esodo di Ifigenia in Aulide, su cui concordano quasi tutti gli editori, può comportare conseguenze decisive sul piano dell’interpretazione della tragedia. Infatti, in alcuni studi recenti, basati sull’edizione Kovacs (Loeb Classical Library, London 2002), che espunge la parte finale relativa al racconto del messaggero con la sostituzione animale, la morte di Ifigenia viene considerata la vera conclusione della tragedia. Da qui è derivata un’interpretazione in chiave politica del sacrificio, secondo la quale, conclusasi negativamente la guerra con Sparta e in assenza di una valida classe dirigente, la morte di un’innocente sarebbe necessaria alla reali…
Promuovere negli uomini la scelta di prepararsi all’esercizio della professione di maestro di scuola primaria
2022
The sixth principle of the Charte de la Ligue Internationale de l’Education Nouvelle of 1921 emphasizes the concept of coeducation. The definition of this concept provides interesting insights to launch a proactive debate on the need to increase the male presence in primary school teaching staff. First of all, some results of empir- ical research that support the request to increase the number of male teachers in the primary school are displayed. Secondly, the most significant measures adopted by some States to promote the figure of the male primary school teacher are described. Finally, a few proposals are made on what could be done in Italy.
Favoreggiamento dell’immigrazione irregolare: la Corte costituzionale dichiara illegittima l’aggravante per chi agevola l’immigrazione utilizzando se…
2022
La Corte costituzionale dichiara l'illegittimità costituzionale della fattispecie aggravata di favoreggiamento dell'immigrazione irregolare tipizzata dall'art. 12, 3° comma, lett. d), d.leg. 25 luglio 1998 n. 286 (t.u. immigrazione), limitatamente alle parole «utilizzando servizi internazionali di trasporto, ovvero documenti contraffatti o alterati o comunque illegalmente ottenuti», per contrasto con il principio di uguaglianza-ragionevolezza (art. 3 Cost.) e con il principio di proporzionalità della sanzione penale (art. 3, 27, 3° comma, Cost.). Eventuali altri interventi della Corte che dovessero muovere nella direzione di un'ulteriore valorizzazione del principio di proporzionalità e rag…
In situ Laser Induced Breakdown Spectroscopy as a tool to discriminate volcanic rocks and magmatic series, Iceland.
2015
7 pages; International audience; This study evaluates the potentialities of a lab-made pLIBS (portable Laser-Induced Breakdown Spectroscopy) to sort volcanic rocks belonging to various magmatic series. An in-situ chemical analysis of 19 atomic lines, including Al, Ba, Ca, Cr, Cu, Fe, Mg, Mn, Na, Si, Sr and Ti, from 21 sampled rocks was performed during a field exploration in Iceland. Iceland was chosen both for the various typologies of volcanic rocks and the rugged conditions in the field in order to test the sturdiness of the pLIPS. Elemental compositions were also measured using laboratory ICP-AES measurements on the same samples. Based on these latter results, which can be used to ident…
Study of the natural cactus extracts protective effects on oxidative stress and inflammation related to peroxisomal β-oxidation deficiencies
2023
The objective of my thesis work was to better understand the role of microglial cells in neuroinflammation initiated in several neurovegetative peroxisomal leukodystrophies and to explore the protective effects of substances from the cactus Opuntia ficus indica. To this end, we used as an in vitro model microglial cells deficient in ATP Binding Cassette D transporters (ABCD 1 and ABCD 2) or acyl-CoA oxidase 1 (ACOX1). These are two BV-2 murine cell lines, deficient in Abcd1/Abcd2-/- or deficient in Acox1-/-, obtained elsewhere by gene editing using the CRISPR/Cas9 methodology. Our results made it possible to: (i) characterize, by differential centrifugation and isopycnic ultracentrifugation…
Evaluation of antitumor and immunomodulatory properties of Indicaxanthin from Opuntia Ficus Indica (L. Mill) fruit
2020
Cancer is a growing health problem around the world and according to estimates from the International Agency for Research on Cancer (IARC), 14.1 million new cancer cases and 8.2 million cancer deaths worldwide have been reported in 2012 (Ferlay et al., 2015). By 2030, the global burden is expected to grow to 21.7 million new cancer cases and 13 million cancer deaths simply due to the growth and aging of the population. Indicaxanthin ((2S)-2,3-dihydro-4-[2-[(2S)-2a-carboxypyrrolidin-1- yl]ethenyl]pyridine-2a,6-dicarboxylic acid), a betalain pigment from cactus pear fruit, has been the object of sound experimental work over the latest years. As many phytochemicals, indicaxanthin is a redox-ac…
Virtual Space and the Contention over Representations of the City
2015
The European Capital of Culture (ECOC) is one of the longest running cultural initiatives of the European Union (EU). The EU annually designates one or more cities with this much-competed-for city brand. In various cities the ECOC designation has caused tensions and disagreements over the decision-making process, funding of cultural events, and the use of urban space. These disputes have also generated urban activism that uses various platforms to contest ECOC policies: public discussions in the local media, Internet sites and blogs, as well as alternative events and activities organised by the citizens themselves. This chapter investigates the conflict related to the ECOC designation of Tu…
Visibility in mediated borderscapes : The hunger strike of asylum seekers as an embodiment of border violence
2018
In 2012, two Afghan asylum seekers camped outside the Parliament building in Helsinki during a hunger strike that lasted for 72 days. Although the protest was very visible in the city space, the mainstream media and most politicians ignored it. This paper analyzes the protest and its mediation through the concepts of borderscape and visibility. Using methods of visual and discourse analysis, we examine the ways in which the hunger strike protest – and its mediation – negotiate the (in)visibility of borders. We show how the city can be a site for both policing and for politicizing asylum issues. In particular, we focus on the ways in which protesting asylum seekers embody borders and border …
