Interventistica eco-guidata per l’articolazione d’anca

2013

Lo scopo di questo lavoro è di rivedere le principali applicazioni della interventistica eco-guidata d’anca, descrivendone le indicazioni e la metodologia. L’ecografia è una metodica considerata sicura per i pazienti, in quanto non è stato dimostrato un possibile danno dovuto all’energia trasmessa dagli ultrasuoni ai tessuti del paziente, contrariamente alle metodiche che fanno uso di radiazioni ionizzanti, come la radiografia convenzionale e la tomografia computerizzata. Inoltre, l’ecografia risulta rapida ed efficace nel guidare l’ago verso la sede voluta evitando di intercettare strutture vascolari e/o nervose, consentendo quindi una maggiore sicurezza, rispetto alle tecniche interventis…

Volume scanning in the evaluation of fetal malformations: a new dimension in prenatal diagnosis

1995

Three-dimensional ultrasound examination was performed in 204 patients with a fetal malformation detected by conventional ultrasound. The patients were examined between 13 and 40 weeks of gestation. The ultrasound equipment used was a Combison 330 and a Combison 530 (Kretztechnik, Austria) with an abdominal Voluson sector transducer (3.5/5 MHz) (Kretztechnik, Austria). This ultrasound system can provide a high-quality three-dimensional surface or translucency image of fetal structures similar to that of a photograph or an X-ray image within seconds without an additional expensive work-station. Of the 204 patients examined with three-dimensional ultrasound, this technique proved advantageous…

Estimating hydraulic conductivity of a crusted loamy soil from beerkan experiments in a Mediterranean vineyard

2017

In bare soils of semi-arid areas, surface crusting is a rather common phenomenon due to the impact of raindrops. Water infiltration measurements under ponding conditions constitute a common way for an approximate characterization of crusted soils. In this study, the impact of crusting on soil hydraulic conductivity was assessed in a Mediterranean vineyard (western Sicily, Italy) under conventional tillage. The BEST (Beerkan Estimation of Soil Transfer parameters) algorithm was applied to the infiltration data to obtain the hydraulic conductivity of crusted and uncrusted soils. Soil hydraulic conductivity was found to vary during the year and also spatially (i.e., rows vs. inter-rows) due to…

Reducing Air Pollutants through Road Innovative Intersections

2013

Road pollutant emissions are correlated mainly to infrastructural capacity and to traffic intensity and typology. With the aim to improve road intersections performances in the last years was designed many new geometric layouts, like turbo roundabouts and flower roundabouts. The main objective of this paper is carried out a comparative analysis between conventional and innovative roundabouts in terms of CO, CO2, NO and PM2,5 vehicular emissions, evaluated by means of COPERT Software which is developed as a European tool for the calculation of emissions from the road transport sector.

"Naissance, consécration et disparition (?) d'une convention de la constitution: l'exemple de la réserve parlementaire"

2020

This study illustrates the relevance of the concept of « political law » to understand the constitutional law of the French Fifth Republic. Its purpose is to highlight, through the example of the « réserve parlementaire », the normativity of some facts (the existence of the « réserve parlementaire » preceded its consecration by written law), and the inability of written law to fully seize political practices. The prohibition of the « reserve parlementaire » by written law (in 2017) will be legally effective only as long it is politically accepted.

Soil erosion assessment on tillage and alternative soil managements in a Sicilian vineyard

2011

Mediterranean crops favour high erosion rates. Vineyards use to reach the highest soil and water losses due to the lack of vegetation cover. A topographical approach by means of the use of vineyards poles as fixed reference point as erosion markers allowed to quantify high and non-sustainable soil erosion rates on the Sicilian vineyards during 9 years. In order to develop strategies to control the soil losses, seven land management were selected and applied in a typical blanc wine grape vineyard located in southwestern Sicily. Comparable plots were managed traditionally using conventional tillage and alternatively using various cover crops: 1) Vicia faba; 2) Vicia faba and Vicia sativa; 3) …

Logic, Computing and Biology

2015

Logic and Computing are appropriate formal languages for Biology, and we may well be surprised by the strong analogy between software and DNA, and between hardware and the protein machinery of the cell. This chapter examines to what extent any biological entity can be described by an algorithm and, therefore, whether the Turing machine and the halting problem concepts apply. Last of all, I introduce the concepts of recursion and algorithmic complexity, both from the field of computer science, which can help us understand and conceptualise biological complexity.
