The spatial structure of the landscape and ecological system of nature protection in the Upper Oder Valley
2017
The study evaluates the spatial structure of the landscape in the Upper Oder valley along a section of about 100 km. It is a part of the valley with the strongest anthropopressure. According to the theory of ecosystem services, one of the functions of the Oder valley landscape is protection of its biodiversity. It is fulfilled by protecting valuable relicts of pristine ecosystems of the valley and by ensuring the function of an ecological corridor. The most important in it are riparian forests and oak-hornbeam forests, meadows, swamps, peatbogs and old river beds. The spatial structure of the landscape within the test section of the Oder valley is characterized by a considerable mosaic. The…
Il primo concorso per il Palazzo di Giustizia a Roma del 1884. Ricostruzione critica del progetto di Ernesto Basile
2019
1. Breve descrizione dell’oggetto di studio Il concorso del Palazzo di Giustizia di Roma si svolge in quattro fasi svolte tra il 1884 e il 1887. Il progetto per il primo concorso, del 1884, redatto dall’allora giovanissimo Ernesto Basile (Palermo 1857-1932), rivela una grande perizia progettuale che trasforma il complesso programma funzionale in un austero edificio in stile neofiorentino. I disegni originari dell’opera, non realizzata, conservati presso la Dotazione Basile del Dipartimento di Architettura dell’Università di Palermo, sono stati oggetto di studio propedeutico alle fasi di analisi, interpretazione e ricostruzione congetturale del modello digitale. 2. Stato dell’arte e riferime…
Theoretical predictions of wimp-nucleus and neutrino-nucleus scattering in context of dark matter direct detection
2018
The nature of dark matter is at present an open question. Assuming the main component of dark matter consists of weakly interacting massive particles (WIMPs), directly detecting such particle via a scattering process with an atomic nucleus would be a strong probe into properties of dark matter. So far direct detection experiments have not provided a conclusive signal of dark matter. Traditionally the experiments aim to detect a coherent, spin- independent, elastic scattering signal which is enhanced by the square of the nuclear mass number. If the coherent channel is for some reason suppressed for WIMP-nucleus interactions, then spin-dependent interactions become important. In this thesis w…
Applications and non-idealities of submicron Al–AlOx–Nb tunnel junctions
2016
We have developed a technique to fabricate sub-micron, 0.6µm×0.6µm Al-AlOx-Nb tunnel junctions using a standard e-beam resist, angle evaporation and double oxidation of the tunneling barrier, resulting in high quality niobium, as determined by the the high measured values of the critical temperature TC ∼ 7.5 K and the gap ∆ ∼ 1.3 meV. The devices show great promise for local nanoscale thermometry in the temperature range 1 - 7.5 K. Electrical characterization of the junctions was performed at sub-Kelvin temperatures both with and without an external magnetic field, which was used to suppress superconductivity in Al and thus bring the junction into a normal-metal-insulator-superconductor (NI…
Protein tyrosine nitration and thiol oxidation by peroxynitrite-strategies to prevent these oxidative modifications.
2013
The reaction product of nitric oxide and superoxide, peroxynitrite, is a potent biological oxidant. The most important oxidative protein modifications described for peroxynitrite are cysteine-thiol oxidation and tyrosine nitration. We have previously demonstrated that intrinsic heme-thiolate (P450)-dependent enzymatic catalysis increases the nitration of tyrosine 430 in prostacyclin synthase and results in loss of activity which contributes to endothelial dysfunction. We here report the sensitive peroxynitrite-dependent nitration of an over-expressed and partially purified human prostacyclin synthase (3.3 μM) with an EC50 value of 5 μM. Microsomal thiols in these preparations effectively co…
Verifying the predicted risk of extinction based on ecological characteristics
2021
Red List status of species should reflect species extinction risk. Because data are limited and species response has a time lag, species may be threatened by extinction even if they are not Red‐Listed. The ability to predict species risk of extinction from ecological characteristics holds promises for proactively targeting conservation measures to species at high risk. In 2005, the risk of extinction from ecological characteristics was predicted for 81 species of Finnish butterflies. Now, after 15 years and two additional national Red List assessments, these predictions are verified. Species with a higher risk of extinction according to the original ecological extinction risk rank (EERR) ha…
La casa-fábrica de obrar azulejos de Vicente Pedrón y Josefa María Casavall en València (1686-1778)
2023
Las fábricas de azulejos en la ciudad de València del último cuarto del siglo XVII y principio del XVIII elaboraron una producción singular. La continuidad técnica facilitó la evolución estética consiguiendo colores y diseños innovadores de alto nivel cromático. Las noticias sobre la actividad de estos obradores, sus creaciones, y sus autores, no son abundantes y más cuando muchos edificios de la época en estudio repletos de azulejos, han ido desapareciendo con el tiempo. En esta ocasión, recurrimos a la información que proporcionan algunos pleitos generados en el entorno de dichas fábricas con el objetivo de identificar las características de las obras realizadas y los productos que generó…
Characterization of a novel three-dimensional outgrowth model of human bronchial mucosa
2011
Recently it has been hypothesized that a reactivation of the epithelial-mesenchymal trophic unit (EMTU) of the respiratory mucosa, caused by extensive epithelial damage, may be responsible for the pathogenesis of asthma. However, most research on this subject so far has been limited by the unavailability of in vitro models correctly mimicking the three-dimensional architecture of the properly differentiated human bronchial mucosa. For this reason, we have developed a novel 3D outgrowth model, obtained from bronchial biopsies and composed of both human bronchial epithelial cells (goblet and columnar cells) and fibroblasts with their basement membrane. Here we present the preliminary data obt…
