Oscillatory periodic pattern dynamics in hyperbolic reaction-advection-diffusion models
2022
In this work we consider a quite general class of two-species hyperbolic reaction-advection-diffusion system with the main aim of elucidating the role played by inertial effects in the dynamics of oscillatory periodic patterns. To this aim, first, we use linear stability analysis techniques to deduce the conditions under which wave (or oscillatory Turing) instability takes place. Then, we apply multiple-scale weakly nonlinear analysis to determine the equation which rules the spatiotemporal evolution of pattern amplitude close to criticality. This investigation leads to a cubic complex Ginzburg-Landau (CCGL) equation which, owing to the functional dependence of the coefficients here involve…

Ohjelmistoturvallisuuden parantaminen staattisella analyysillä
2018
Staattisella analyysillä tarkoitetaan ohjelmiston ominaisuuksien tarkastelemista kääntämättä tai ajamatta ohjelmistoa. Tämä tutkielma on pienimuotoinen kirjallisuuskatsaus, jonka tarkoituksena on lähdekirjallisuutta tutkimalla ja jäsentämällä tutkia, miten staattisella analyysillä voidaan parantaa nykyaikaisten web-applikaatioiden ohjelmistoturvallisuutta. Tutkitun kirjallisuuden perusteella staattista analyysiä hyödyntävillä työkaluilla on mahdollista havaita yleisiä, liiketoiminnan kannalta erittäin tuhoisia haavoittuvuuksia ja täten parantaa merkittävästi ohjelmistoturvallisuutta. Näiden työkalujen tehokas hyödyntäminen ohjelmistokehityksen kontekstissa vaatii kuitenkin suunnitelmallisuu…
Le categorie per la valutazione della produzione scritta degli studenti
2008
Il contributo presenta una proposta di analisi delle interazioni nei webforum per la costruzione della conoscenza condivisa. La costruzione di una comunicazione valorizzante l’apporto costruttivo di singoli studenti e di un’interazione congruente in rete può essere indagata secondo un aspetto contenutistico e uno di tipo relazionale. In riferimento a questi due aspetti, la produzione scritta di studenti universitari nei forum di discussione è stata analizzata con l’utilizzo di una lista di categorie predefinita (griglia di valutazione). La lista di categorie elaborata prospetta un quadro di possibili comportamenti linguistico-comunicativi messi in atto dagli allievi durante l’attività di in…
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
Vertically Aligned Nanowires and Quantum Dots: Promises and Results in Light Energy Harvesting
2023
The synthesis of crystals with a high surface-to-volume ratio is essential for innovative, high-performance electronic devices and sensors. The easiest way to achieve this in integrated devices with electronic circuits is through the synthesis of high-aspect-ratio nanowires aligned vertically to the substrate surface. Such surface structuring is widely employed for the fabrication of photoanodes for solar cells, either combined with semiconducting quantum dots or metal halide perovskites. In this review, we focus on wet chemistry recipes for the growth of vertically aligned nanowires and technologies for their surface functionalization with quantum dots, highlighting the procedures that yie…

Vinificazione in bianco in presenza di chips di quercia di origine e livello di tostatura diversi
2011
Some musts from Grillo grapes, a cultivar autochthonous of western Sicily, fermented with medium toasted American oak chips or with non toasted French oak chips (Classic Line – HTS enology) have been vinified. the wines were significantly different as regards the contents in volatile and non volatile compounds extracted from American and French oak chips. a slight increase in alcoholic fermentation rate and in some cases a higher content of ethyl esters and medium chain fatty acids, were observed in musts charged with chips, independently of their origin. In wines obtained from musts charged with french medium toasted oak chips, the content in furans was higher (5-methylfurfural, trans-meth…
Flexible and Efficient Computer-Aided Design Tool for Advanced Comb-Line Rectangular Waveguide Filters
2015
A very flexible and efficient computer-aided design (CAD) tool, specifically suited for advanced comb-line rectangular waveguide filters, is presented in this work. The developed software tool, which makes use of a full-wave analysis technique based on the Boundary Integral - Resonant Mode Expansion method, permits to load the considered comb-line resonators with any number of radially symmetrical partial-height metallic posts. The implemented CAD tool also allows for dealing with coupling windows of arbitrary cross-section, thus drastically enhancing the flexibility of the computer-aided design process. The excitation of the analyzed components, which is performed by using generalized coax…
