Farmaci inibitori delle topoisomerasi
2020
Le DNA-topoisomerasi, identificate per la prima volta nel 1971, sono enzimi chiave nella regolazione della struttura topologica del DNA.

Cibo e banchetto rituale nella festa della Beata Vergine del Miracolo di Lula
2019
Sul consumo di alimenti nell’ambito delle feste campestri si tenta di ragionare nel contributo, assumendo a caso emblematico i festeggiamenti che annualmente si rinnovano a Lula, centro rurale in provincia di Nuoro, in onore della Madonna del Miracolo. La costruzione del santuario e l’istituzione della festa sono relativamente recenti (1899) e ciò consente di documentare più agevolmente sensi e funzioni di un tipo di occorrenze cerimoniali diffuse in tutta l’isola, che presentano un iter rituale pressoché analogo e che rimandano a un simbolismo rituale proprio di una società tradizionale di tipo agropastorale. L’esempio preso in esame consentirà di rilevare, inoltre, quando e in che misura …
Control of a PTZ camera in a hybrid vision system
2014
In this paper, we propose a new approach to steer a PTZ camera in the direction of a detected object visible from another fixed camera equipped with a fisheye lens. This heterogeneous association of two cameras having different characteristics is called a hybrid stereo-vision system. The presented method employs epipolar geometry in a smart way in order to reduce the range of search of the desired region of interest. Furthermore, we proposed a target recognition method designed to cope with the illumination problems, the distortion of the omnidirectional image and the inherent dissimilarity of resolution and color responses between both cameras. Experimental results with synthetic and real …

Smart camera design for intensive embedded computing
2005
Computer-assisted vision plays an important role in our society, in various fields such as personal and goods safety, industrial production, telecommunications, robotics, etc. However, technical developments are still rare and slowed down by various factors linked to sensor cost, lack of system flexibility, difficulty of rapidly developing complex and robust applications, and lack of interaction among these systems themselves, or with their environment. This paper describes our proposal for a smart camera with real-time video processing capabilities. A CMOS sensor, processor and, reconfigurable unit associated in the same chip will allow scalability, flexibility, and high performance.
Crassula campestris(Eckl. & Zeyh.) Endl.(Crassulaceae), a new record for the Italian flora
1998
Abstract Brullo, S., Campo, G., Marceno, C., Romano, S. & Siracusa, G.: Crassula campestris (Eckl. & Zeyh.) Endl. (Crassulaceae), a new record for the Italian flora. — Willdenowia 28: 53–58. 1998. — ISSN 0511-9618. Crassula campestris, a species widespread in S Africa, was discovered in Sicily near Palermo, which is a new record for the Italian flora. A description and illustration of C. campestris is provided and the species is compared with C. tillaea and C. basaltica, the two other Crassula species in Sicily.
A new method to measure the size distribution of insoluble submicron particles in water
1994
Abstract In the atmosphere, cloud and fog droplets usually contain insoluble material. The role of these insoluble particles is still unknown today, and is of interest to study. To determine the size distribution and number concentration of these particles in water, different techniques are available. The instrumentation, however, to measure nanometer-sized particles down to 50 nm diameter is not known. A new instrument, the Liquid Tandem Differential Mobility Analyser (LTDMA), was developed to measure size distributions of insoluble particles in water in the size range 50–300 nm in diameter. The new method is based on nebulising, e.g. cloud water and forming a residue aerosol consisting of…
Contribución de las Prácticas de Campo a la construcción del Conocimiento Profesional del Profesorado de Biología. Un estudio con futuros docentes de…
2018
En el ámbito de las Ciencias Naturales y la Biología, las Prácticas de Campo constituyen un eje fundamental de su enseñanza y aprendizaje, promoviendo especialmente la puesta en valor de la biodiversidad, la generación de actitudes en pro de la conservación de los seres vivos y el contacto directo con los entornos naturales. Sin embargo, son escasos los profesores de ciencias que las emplean en su práctica docente, en parte debido a la escasa formación sobre cómo enseñar Biología en la naturaleza. Concretamos nuestra investigación en la construcción del Conocimiento Profesional de los futuros profesores de Ciencias Naturales, contextualizándola en la Universidad Surcolombiana (Neiva-Colombi…
