Teleradiologie nach Röntgenverordnung - beispielhafte Anwendung der Open-Source-Software SecTelMed
2005
Purpose: Establishing a teleradiology connection according to the Rontgenverordnung (RoV) between a peripheral hospital and a university clinic will contribute to improve the radiological emergency treatment on weekends, holidays and at night. It will also better the medical care for patients and help to lower the costs. Materials and Methods: By using the open source software SecTelMed, the radiological picture is transferred via an internet-linked SSH communication server. The integration of the teleradiological data transfer into the actual workflow is attained by using the already existing PACS infrastructure. While its installation is still under construction, it is actually employed f…
La scoperta, sistemazione e conservazione della grande Iscrizione di Gortina, nell'isola di Creta (1884-1921): la protezione delle testimonianze e le…
2013
La scoperta e la conservazione della Grande Iscrizione di Gortina a Creta, da parte degli studiosi italiani, fra la fine del XIX sec. e i primi decenni del XX sec., rappresentò un grande riconoscimento scientifico-culturale per la giovane nazione italiana. Nel passato, l’isola di Creta era stata legata alla Repubblica di Venezia e anche questo rapporto favorì l’invio a Creta del giovane epigrafista F. Halbherr, il quale fra notevoli peripezie rinvenne, assieme all’epigrafista tedesco E. Fabricius, la famosa l’iscrizione nell’antica città di Gortina. L’iscrizione, fra le più antiche e complete finora conosciute in tutta Europa, conteneva le norme sulla famiglia, l’eredità e in generale i dir…
Riflessioni comparatistiche sulla revoca della cittadinanza per reati di terrorismo
2023
l fenomeno dei cosiddetti “foreign fighters” e il verificarsi di attacchi terroristici in alcuni paesi dell’Unione europea hanno sollevato la questione relativa alla privazione della cittadinanza come misura di contrasto e tutela della sicurezza pubblica. Questo articolo intende contribuire al dibattito sulla legittimità giuridica di tale misura, esaminando i recenti sviluppi della legislazione in materia e le sue applicazioni in Belgio, Francia, Regno Unito e Italia.
Synthesis and characterisation of a ternary composite of polyaniline, reduced graphene-oxide and chitosan with reduced optical band gap and stable aq…
2019
A ternary composite comprising of p-toluene sulfonic acid doped polyaniline (PANI), chitosan and reduced graphene oxide (RGO) with stable aqueous dispersibility has been synthesised via oxidative polymerisation of aniline in chitosan/RGO dispersion. For comparison; PANI, PANI/chitosan and PANI/RGO composites were also synthesised using the same procedure. FTIR, Raman, XPS, XRD and UV-VIS confirmed the successful synthesis of the PANI and the composites. The aqueous dispersions of the PANI/chitosan and the ternary composites were found to be stable even after more than four months. The stability of the dispersion was attributed to the polycationic nature of the chitosan. The thermogravimetri…
The Preservation of Sicilian Forests with Poorly Mechanized Logging Processes
1997
Abstract In the province of Agrigento (Sicily), owing to lack of funds, machinery and permanently employed workers, it is necessary to forecast costs and time required for thinning out about 1500 ha of artificial forest using only chain saws and temporarily employed manpower. This study was made to find out how costs and labour productivity vary with tree species, age, size, forest density, land orography and ground uneveness, in order to decide in which areas the change from artificial to natural forest, by gradually thinning out the non-autochthonous trees, could be done at the least cost. Logging processes have been monitored at nine different test sites of about 1 ha each. The results s…
Analysis of tide measurements in a Sicilian harbour
2011
Designing of ports and coastal protection works as well as planning of coastal human activities require knowledge of tidal oscillations. The latter vary noticeably from site to site and present an “astronomic” component, which is roughly periodic, and a “meteorological” component which is usually considered as random. In this paper, the tidal oscillations observed in a Sicilian harbour in the period 1999-2009 are analysed statistically, in order to recognize a probability distribution which allows one to predict the highest tidal levels. First, the measurements are used to obtain, for each year, the astronomic tide by the harmonic analysis by the software package T_TIDE. The difference betw…
Tiesību normu laika aspekti tiesiskā un demokrātiskā valstī
2015
Promocijas darbā „Tiesību normu laika aspekti tiesiskā un demokrātiskā valstī” ir izpētīts, kuros gadījumos likumdevējs ir tiesīgs pieņemt tiesību normas ar iedarbību uz pagātnē izveidotām tiesiskajām attiecībām. Izveidotu tiesisko attiecību ietekmēšana ir izvērtējama, balstoties uz tiesiskās paļāvības principu. Lai noskaidrotu, vai tiesiskās paļāvības princips ir aizskarts, ir jākonstatē, vai tiesību normām ir atpakaļejošs spēks laikā. Atšķirībā no sodu tiesībām, kur atpakaļejošs spēka identificēšana per se padara tiesību normas par prettiesiskām, citās tiesību nozarēs pēc atpakaļejoša spēka konstatēšanas vēl būtu jāizvērtē, vai sabiedrības interešu aizsardzība nav iespējama ar mazāku ieja…
Unveiling distribution patterns of freshwater phytoplankton by a next generation sequencing based approach.
2012
The recognition and discrimination of phytoplankton species is one of the foundations of freshwater biodiversity research and environmental monitoring. This step is frequently a bottleneck in the analytical chain from sampling to data analysis and subsequent environmental status evaluation. Here we present phytoplankton diversity data from 49 lakes including three seasonal surveys assessed by next generation sequencing (NGS) of 16S ribosomal RNA chloroplast and cyanobacterial gene amplicons and also compare part of these datasets with identification based on morphology. Direct comparison of NGS to microscopic data from three time-series showed that NGS was able to capture the seasonality in…
Effect of environmental conditions on the durability of polycarbonate for the protection of cultural heritage sites.
2019
Polycarbonate is a good material for covering and protecting cultural heritage sites because of its durability, mechanical properties, and transparency. However, polycarbonate degrades under environmental weathering with a significant decrease of physical and mechanical properties and loss of transparency. In this work, the contemporary presence of ultraviolet irradiation and different temperature and moisture conditions have been taken into account to study the environmental degradation of this polymer with regard to its mechanical and optical properties. The photo-oxidation reactions cause a decrease in the molecular weight and the formation of many oxygenated species. The hydrolytic sci…
Cavitation corrosion and repassivation kinetics of titanium in a heavy brine LiBr solution evaluated by using electrochemical techniques and Confocal…
2011
The cavitation corrosion behaviour of commercially pure Grade 2 titanium in a 992 g/l LiBr solution has been investigated at 25 °C using an ultrasound device. Cavitation was found to have more influence on the anodic branch than on the cathodic branch, shifting the corrosion potential, Ecorr, and the OCP value towards more negative potentials, and increasing the corrosion current density, icorr, by six times. The repassivation kinetics of Grade 2 titanium have also been studied in the 992 g/l LiBr solution, at 25 °C and various applied potentials, using cavitation to damage the electrode surface. The repassivation kinetics have been analysed in terms of the current density flowing from the …
