Development of an immunochromatographic assay based on carbon nanoparticles for the determination of the phytoregulator forchlorfenuron
2013
Rapid analytical methods enabling the determination of diverse targets are essential in a number of research areas, from clinical diagnostics to feed and food quality and safety. Herein, the development of a quantitative immunochromatographic assay for the detection of the synthetic phytoregulator forchlorfenuron (CPPU) is described. The competitive lateral flow immunoassay (LFIA) was based on the immobilization onto a nitrocellulose membrane of an ovalbumin-CPPU conjugate (test line) and on the use of an immunodetection ligand consisting of carbon nanoparticles labeled with an anti-CPPU monoclonal antibody through interaction with a secondary antibody. The presence of CPPU in horticultural…
A Comparative Eye Tracking Study of Usability—Towards Sustainable Web Design
2021
Websites are one of the most frequently used communication environments, and creating sustainable web designs should be an objective for all companies. Ensuring high usability is proving to be one of the main contributors to sustainable web design, reducing usage time, eliminating frustration and increasing satisfaction and retention. The present paper studies the usability of different website landing pages, seeking to identify the elements, structures and designs that increase usability. The study analyzed the behavior of 22 participants during their interaction with five different landing pages while they performed three tasks on the webpage and freely viewed each page for one minute. Th…
Webcam based display calibration
2012
International audience; We present an automatic method for measuring the tone response curve of display devices based on visual methods, where the eye is replaced by an end-user, uncalibrated camera, such as a webcam. Our approach compares a series of halftoned patches of known covering ratio with a continuous series of tone patches for each ratio. Both patches are shot by a camera that is used as a virtual eye to evaluate the luminance difference. By an iterative process, the continuous tone value is adjusted while compared with the perceived level of the halftoned patch. When the camera does not see any difference between the patches or a minimal difference, the luminance level of the con…
Ginger and Turmeric Essential Oils for Weed Control and Food Crop Protection
2019
Ginger and turmeric are two food ingredients that are in high demand due to their flavor and positive effects on health. The biological properties of these spices are closely related to the aromatic compounds they contain. The chemical compositions of their essential oils and their in vitro phytotoxic activity against weeds (Portulaca oleracea, Lolium multiflorum, Echinochloa crus-galli, Cortaderia selloana, and Nicotiana glauca) and food crops (tomato, cucumber, and rice) were studied. Forty-one compounds, accounting for a relative peak area of 87.7% and 94.6% of turmeric and ginger essential oils, respectively, were identified by Gas Chromatography&ndash

Essential oil crops for sustainable agriculture - A review
2009
Multifunctionality and diversification of farming systems, integration of agricultural practices both inter se and with the non-agricultural productive systems operating on the territory, biodiversity safeguards, and reduction in off-farm inputs, are key factors for all modern development strategies in agricultural areas. Such issues are valid worldwide, but are especially true in areas in which the cultivation of the more widespread and “classical” crops is constrained by factors of varying degree and importance. In Mediterranean areas, where many environmental and economic factors often reduce rural areas to marginal conditions, the search for new crop opportunities has become one of the …
Representations of the Life-giving Spring feast in Romanian iconography
2021
This article explores the development of the theme of the Life-giving Spring in Byzantine iconography. The path towards its establishment was initiated at the moment when a representation rule, an original convention was set. Thereafter, because of its diffusion in time and space, the theme became enriched by particular mentalities and sensibilities of the epochs and the communities that adopted it as a form of devotion for the Virgin Theotokos. As a result, the representations we have known so far are extremely varied. Contribution: The final purpose of this approach, as well as its contribution, is to highlight the diverse unity of the iconographic tradition and illustrate both the evolut…
Due sculture lignee del Settecento tra Napoli e Palermo: l’Immacolata Concezione di Piazza Armerina e il San Michele Arcangelo di Cerami
2022
Oggetto del contributo sono l'Immacolata Concezione e il San Michele Arcangelo custoditi rispettivamente nella Cattedrale di Piazza Armerina e nella Chiesa Madre di Cerami, centri dell'entroterra siciliano. La prima opera è ricondotta per la prima volta ad ignoto scultore napoletano del primo quarto del Settecento, la seconda, invece, è attribuita a Filippo Quattrocchi. I manufatti lignei, restaurati di recente, vengono indagati in riferimento alla pertinente temperie culturale e, pertanto, raffrontati con altri simulacri coevi Subject of the contribution are the Immaculate Conception and the Archangel Michael kept respectively in the Cathedral of Piazza Armerina and in the Mother Church of…
Legni mediterranei Simulacri intagliati nella Sicilia del Settecento
2023
Il volume esamina, per la prima volta, i simulacri lignei del Settecento custoditi nelle chiese, nei Musei Diocesani e nelle collezioni private dell’Isola. Sono opere che, a grandezza naturale e di forte impatto emotivo, furono commissionate da prelati, confraternite, devoti e nobili. Le sculture, alcune restaurate altre in cattivo stato di conservazione, sono state approntate, secondo la pertinente temperie culturale, da artisti siciliani e napoletani, talora su prototipi di manufatti presenti a Roma. Divulgatori della produzione artistica capitolina in Sicilia furono l’architetto Giacomo Amato, il pittore Vito D’Anna, gli scultori Giovan Battista Ragusa e Ignazio Marabitti, non a caso doc…
La scultura lignea del Settecento nella Sicilia occidentale tra importazioni da Napoli e scuole locali
2022
Dopo una premessa sui committenti, si indagano i più rappresentativi simulacri lignei del XVIII secolo della Sicilia occidentale. Le statue sono state eseguite, secondo la pertinente temperie culturale, da scultori locali, talvolta ignari dei tratti innovativi del tempo, che hanno reiterato stilemi dei secoli precedenti. Tra gli artisti con bottega a Palermo, aggiornati alle più moderne istanze, si annoverano Barcellona, Quattrocchi e Valenza. Altri manufatti, perlopiù ubicati nelle chiese degli ordini religiosi, sono stati approntati da autori napoletani su esplicita richiesta di attenti committenti. Alle opere partenopee va il merito di aver contribuito all’aggiornamento del linguaggio ar…
