Wyspa w krajobrazie jako problem regionalizacji fizyczno-geograficznej na przykładzie Garbu Opola
2016
W regionalizacji fizyczno-geograficznej Polski obszar Garbu Opolskiego zaliczony został do makrore-gionu Nizina Śląska i mezoregionu Pradolina Wrocławska. Kwalifikacja ta nie jest zgodna z kryteria-mi wyróżniania mezoregionów i makroregionów. Garb Opolski pod względem budowy geologicznej może być identyfikowany jako część nieodległej Wyżyny Śląskiej, choć położony jest na znacząco mniejszej wysokości niż granica hipsometryczna między nizinami a wyżynami. Przykład Garbu Opolskiego pokazuje problem określenia przynależności wyspowych jednostek fizyczno-geograficznych na pograniczu wyżyn i nizin Polski. Na podstawie przeprowadzonych badań wska-zano na dwie możliwości rozwiązania podobnych prob…
Brevi considerazioni su piogge intense e potenzialità di produzione del deflusso superficiale in Sicilia
2013
Vengono presentati i metodi aggiornati per la stima delle precipitazioni intense massime annue di fissato tempo di ritorno in Sicilia. Dall‟osservazione della distribuzione spaziale dei parametri assunti nei modelli di stima emergono aree a maggior rischio riguardo l‟intensità di pioggia, qui commentate. Il richiamo a recenti studi che riguardano la produzione del deflusso superficiale a scala media annua o a scala di evento, consente di avanzare alcune considerazioni di tipo spaziale, con particolare attenzione all‟area del messinese, su questa importante propensione idrologica notoriamente fonte di dissesto idrogeologico e di pericolo alluvionale. The updated methods for the estimation of…
Role of en and novel interactions between msh, ind, and vnd in dorsoventral patterning of the Drosophila brain and ventral nerve cord
2010
AbstractSubdivision of the neuroectoderm into discrete gene expression domains is essential for the correct specification of neural stem cells (neuroblasts) during central nervous system development. Here, we extend our knowledge on dorsoventral (DV) patterning of the Drosophila brain and uncover novel genetic interactions that control expression of the evolutionary conserved homeobox genes ventral nervous system defective (vnd), intermediate neuroblasts defective (ind), and muscle segment homeobox (msh). We show that cross-repression between Ind and Msh stabilizes the border between intermediate and dorsal tritocerebrum and deutocerebrum, and that both transcription factors are competent t…

Generation of Natural Runoff Monthly Series at Ungauged Sites Using a Regional Regressive Model
2016
Many hydrologic applications require reliable estimates of runoff in river basins to face the widespread lack of data, both in time and in space. A regional method for the reconstruction of monthly runoff series is here developed and applied to Sicily (Italy). A simple modeling structure is adopted, consisting of a regression-based rainfall–runoff model with four model parameters, calibrated through a two-step procedure. Monthly runoff estimates are based on precipitation, temperature, and exploiting the autocorrelation with runoff at the previous month. Model parameters are assessed by specific regional equations as a function of easily measurable physical and climate basin descriptors. Th…
Annual runoff regional frequency analysis in Sicily
2009
Abstract This paper performs annual runoff frequency analysis in Sicily, Italy using the index runoff method. Homogeneous regions, not necessarily defined by geographical boundaries but sharing common features from a morphologic and climatic standpoint, have been identified. For each region a single probability distribution function can be fitted to the available annual runoff data scaled by the index runoff. Starting from an initial dataset of 105 hydrometric stations, 57 stations have been selected using heuristic criteria associated with the Hosking and Wallis’s discordancy measure. The Mantel tests have been then applied to find out the physical and morphological parameters best correla…

Propozycja regionalizacji fizycznogeograficznej Sudetów Wschodnich
2018
Artykuł przedstawia propozycję wyznaczenia granic Sudetów Wschodnich oraz podziału fizycznogeograficznego makroregionu na mezoregiony. Przy wyznaczaniu granic uwzględniono w większym stopniu genetyczno-geologiczny podział Sudetów związany z orogenezą waryscyjską. W podziale na mezoregiony w większym stopniu uwzględniono kryteria litostratygraficzne.
Key-indicators for maternity hospitals and newborn readmission in Sicily
2017
This paper proposes a composite indicator for the classification of maternity units, which takes into account for the different dimensions of service delivery, as potential predictors of health outcomes. As a measure of outcome, infant readmissions is considered, being a proxy of morbidity. The results highlight that after controlling for risk factors of the newborn, and for the presence of neonatal intensive unit, infants born in lower level hospitals show readmission rates higher than infants born in higher level hospitals.
Regional-scale modeling of reference evapotranspiration: Intercomparison of two simplified temperature- and radiation-based approaches
2015
Two regionalized models for the distributed estimation of daily reference evapotranspiration, the temperature-based Hargreaves (HE) and the radiation-based Makkink (MK) equations, are applied in Southern Italy during the years 2007 and 2008. Spatially distributed meteorological inputs, such as air temperature and incoming solar radiation, were derived from geostatistical interpolation of ground data and from the Land Surface Analysis Satellite Application Facility (LSA-SAF) surface radiation product, respectively. Comparison of the latter with 83,394 daily measurements provided by 128 weather stations shows a not negligible seasonal error in daily solar radiation that is corrected by means …
