L’ineffabile terza mediana dell'Anvur per l’area 12
2012
L'articolo affronta lo spinoso problema del ranking delle riviste giuridiche nell'ambito della procedura di abilitazione scientifica nazionale per professori associati e ordinari. In particolare si sofferma sui problemi di legittimità che derivano della sopravvenuta pubblicazione delle riviste di classe A e dalla eventuale introduzione della terza mediana a cui la detta pubblicazione prelude, nel quadro della critica della classificazione Anvur in disaccordo con i pareri espressi dalla comunità accademica. The article discusses the thorny problem of legal journals ranking, focusing it in relation to national scientific qualification procedure. In particular, it stays on problems of low-…
Geomorphology of the urban area of Palermo (Italy)
2020
The results of a geomorphological study carried out in the urban area of Palermo are summarized in a thematic map. Field survey, analysis of aerial photographs and topographic maps, consultation of historical documents and maps, stratigraphic and topographic reconstruction from numerous wells and subsoil data, and bibliographic search were performed, in order to display the geomorphological changes produced by man over time in a densely populated area and to define the Anthropocene of the study area. Palermo town rises along large marine terrace surfaces cut by small river valleys and bordered by wide degraded and abandoned coastal cliffs. Over the last 2700 years, this area was affected by…

A Combined Multi-Cohort Approach Reveals Novel and Known Genome-Wide Selection Signatures for Wool Traits in Merino and Merino-Derived Sheep Breeds.
2019
Merino sheep represents a valuable genetic resource worldwide. In this study, we investigated selection signatures in Merino (and Merino-derived) sheep breeds using genome-wide SNP data and two different approaches: a classical F-ST-outlier method and an approach based on the analysis of local ancestry in admixed populations. In order to capture the most reliable signals, we adopted a combined, multi-cohort approach. In particular, scenarios involving four Merino breeds (Spanish Merino, Australian Merino, Chinese Merino, and Sopravissana) were tested via the local ancestry approach, while nine pair-wise breed comparisons contrasting the above breeds, as well as the Gentile di Puglia breed, …
The responsibilities of extra familial care institutions’ children as important personality characteristics development process
2014
The questions about how and in which living activity areas the responsibility of extra familial care institutions’ children as important personality characteristic is developed, in this paper are investigated. Responsibility category includes the problem of philosophy and sociology – the extent of which a person is able and can be the subject (the author) of his activity, as well as specific questions: the ability of the person knowingly (intentionally, voluntarily) to execute determined requirements and to perform specified tasks; to make certain choice; to achieve determined results, as well as to solve the issues. The concept of responsibility is described in various scientific papers. E…
The Synthesis, Characterization and Sintering of Nickel and Cobalt Ferrite Nanopowders
2012
The NiFe2O4 and CoFe2O4 ferrites were synthesized by two methods – chemical sol-gel self-combustion method and the high frequency plasma chemical synthesis and magnetic properties, crystallite size, specific surface area of synthesized products are characterized. Nanopowders synthesized in the high frequency plasma are with specific surface area in the range of (28 – 30) m2/g (the average particle size (38 – 40) nm, crystallite size ~40 nm). The ferrite nanopowders obtained by sol-gel self-combustion method have the specific surface area of (37 – 43) m2/g (average particle size (26 – 31) nm, crystallite size (10 – 20) nm). All synthesized nanopowders were sintered via pressure-less sinterin…
Investigations of Latvian Illite/Kaolinite Clays Irradiated Under Action of Accelerated Electrons
2019
Natural clay is a perspective material for application as sorbents for wastewater treatment as well as for sorption of radionuclides, where the properties of the clays can be changed under influence of ionizing radiation. For application of Latvian illite/kaolinite clays for isotope sorption it is important to characterize the physic-chemical properties of pre-prepared air dried clays. Two fractions of the illite clays were selected. A fraction with grain size 100 μm (SiO2 content 60.9 ± 1.5 wt.%, specific surface area 35 m2/g) and a sand free fraction – 2 μm (SiO2 47.7 ± 1.9 wt.%, specific surface area 38 m2/g). Selected fractions were irradiated with accelerated electrons (5 MeV, ELU-4, S…
Application of Tuning Fork Sensors for In-situ Studies of Dynamic Force Interactions Inside Scanning and Transmission Electron Microscopes
2012
Mechanical properties of nanoscale contacts have been probed in-situ by specially developed force sensor based on a quartz tuning fork resonator (TF). Additional control is provided by observation of process in scanning electron microscope (SEM) and transmission electron microscope (TEM). A piezoelectric manipulator allows precise positioning of atomic force microscope (AFM) probe in contact with another electrode and recording of the TF oscillation amplitude and phase while simultaneously visualizing the contact area in electron microscope. Electrostatic control of interaction between the electrodes is demonstrated during observation of the experiment in SEM. In the TEM system the TF senso…
Crop Nitrogen Retrieval Methods for Simulated Sentinel-2 Data Using In-Field Spectrometer Data.
2021
Nitrogen (N) is one of the key nutrients supplied in agricultural production worldwide. Over-fertilization can have negative influences on the field and the regional level (e.g., agro-ecosystems). Remote sensing of the plant N of field crops presents a valuable tool for the monitoring of N flows in agro-ecosystems. Available data for validation of satellite-based remote sensing of N is scarce. Therefore, in this study, field spectrometer measurements were used to simulate data of the Sentinel-2 (S2) satellites developed for vegetation monitoring by the ESA. The prediction performance of normalized ratio indices (NRIs), random forest regression (RFR) and Gaussian processes regression (GPR) f…
Eficacia de la retroalimentación formativa para mejorar estrategias de competencia lectora en enseñanza secundaria
2013
El objetivo general de la presente tesis doctoral es analizar la efectividad de la retroalimentación formativa para mejorar estrategias de competencia lectora en estudiantes de Enseñanza Secundaria. La investigación actual (Vidal-Abarca, Mañá y Gil, 2010) y los resultados de la evaluación del programa PISA (OECD, 2010), han mostrado que es necesario diseñar intervenciones para fomentar que los estudiantes españoles se conviertan en lectores competentes. La retroalimentación formativa constituiría un procedimiento instruccional apropiado para promover la adquisición de estrategias de auto-regulación dirigidas a mejorar la competencia lectora (Butler y Winne, 1995). Específicamente, el presen…
