Gli Angiomi Primitivi Dei Muscoli Striati
1957
Starting from a personal observation of primary angioma of the left pectoralis major, investigations on muscle angiomas are resumed, with the purpose of completing the latest statistical analyses. 75 new cases are reviewed which, added to those from Shallow, Eger and Wagner, bring the number of angiomas referred in the literature up to 111. The etiopathogenesis, pathological anatomy and symptomatology of this affection are considererd and the differential diagnosis, still very difficult, is discussed. A diagnostical misunderstanding may be avoided or limited by thinking of this possible occurrence. The numerous means, currently available for an easier diagnosis are exposed, like direct roe…
Genome-Wide Analyses Identifies Known and New Markers Responsible of Chicken Plumage Color
2020
Simple Summary In order to assess sources of variation related to Polverara breed plumage color (black vs. white), we carried out genome-wide analyses to identify the genomic regions involved in this trait. The present work has revealed new candidate genes involved in the phenotypic variability in local chicken populations. These results also contribute insights into the genetic basis for plumage color in poultry, and confirm the great complexity of the mechanisms that control this trait. Abstract Through the development of the high-throughput genotyping arrays, molecular markers and genes related to phenotypic traits have been identified in livestock species. In poultry, plumage color is a…

Pulse rate variability measurement with camera-based photoplethysmography
2021
Electrocardiogram (ECG) has been used by doctors and biomedical researchers to measure cardiac parameters such as Heart Rate (HR) and Heart Rate Variability (HRV). HR is a medical index for health monitoring and the HRV is a sign to reflect the activities of Autonomic Nervous System (ANS) and can be used for emotion recognition applications. Recently, remote photoplethysmography (rPPG) has evolved as a non-contact technique for measuring vital cardiac signs. Compared with ECG, this technique is non-invasive, low-cost, comfortable and possibly utilized in long-term monitoring. It has great potential in remote health assessment and emotion detection. However, the rPPG is a video-based method,…
Monthly Bonaire coral Sr/Ca and oxygen isotope data from 118 kyr ago (coral BON-5-D)
2015
The end of the last interglacial period, ~118 kyr ago, was characterized by substantial ocean circulation and climate perturbations resulting from instabilities of polar ice sheets. These perturbations are crucial for a better understanding of future climate change. The seasonal temperature changes of the tropical ocean, however, which play an important role in seasonal climate extremes such as hurricanes, floods and droughts at the present day, are not well known for this period that led into the last glacial. Here we present a monthly resolved snapshot of reconstructed sea surface temperature in the tropical North Atlantic Ocean for 117.7±0.8 kyr ago, using coral Sr/Ca and d18O records. W…
Sedimentology of a Late Quaternary lacustrine record from the south-eastern Carpathian Basin
2021
The Upper Pleistocene geoarchives in the south‐eastern Carpathian Basin are represented predominantly by loess–palaeosol records. In 2015, a 10 m sediment core composed of clay‐rich lacustrine sediments was recovered by vibracoring a dry lake basin located between the Vršac Mountains (Serbia) and the Banat Sands in the south‐eastern Carpathian Basin; a location relevant for placing regional archaeological results in a palaeoenvironmental context. Here, we present results from geoelectrical prospection and a lithostratigraphic interpretation of this sequence supported by a detailed granulometric study supplemented by ostracod analysis. An age model based on luminescence dating is discussed a…
I ‘vasi di Centuripe’: per un approccio integrato
2017
Il contributo intende evidenziare le prospettive di un approccio interdisciplinare integrato allo studio della ceramica policroma “di Centuripe”. Dagli inizi del XX secolo, tale classe ha riscosso ampio apprezzamento per le sue delicate pitture e la ricchezza di ornamenti a rilievo applicati (dipinti e dorati) che abbelliscono i vasi, rendendoli pressoché inutilizzabili nella pratica per scopi funzionali, ma altamente efficaci come doni funerari in antico, e oggi come pezzi di grande impatto per commercianti di antichità e collezionisti moderni. Data la piaga, diffusa fino a tempi recenti, degli scavi clandestini, dei “restauri” arbitrari e delle falsificazioni, i vasi di Centuripe necessit…
The beginning of western greek amphorae production in western Sicily: archaeometric and archaeological studies on 6th–5th centuries BCE amphorae manu…
2020
About 560 western Greek amphorae (6th–5th centuries BCE) re-used in enchytrismos burials were unearthed in the necropolis of the Dorian-Chalcidian colony of Himera in northwestern Sicily. Among the most striking issues is the determination of their geographical provenance. For this purpose, ceramic samples chipped from freshly broken surfaces of all the amphorae were first subdivided into macrofabrics by the use of a hand lens. Thereon, the samples were studied in accordance with standardized methods by the use of reflected light microscopy. Due to the special focus of our project on the characterization of Sicilian productions, a selection of amphorae which showed visible, macroscopic affi…
Nanoelectron spectroscopy for chemical analysis: a novel energy filter for imaging x-ray photoemission spectroscopy
2005
An ovel instrument for imaging ESCA is described. It is based on a tandem arrangement of two hemispherical energy analysers used as an imaging energy filter. The main spherical aberration (α 2 -term) of the analyser is corrected by the antisymmetry of the tandem configuration. The kinetic energy range useable for imaging extends up to 1.6 keV; this is compatible with Mg and Al Kα laboratory x-ray sources. First experiments on the chemical surface composition of a Cu0.98Bi0.02 polycrystal, a GaAs/AlGaAs heterostructure and Ag crystallites on Si(111) have been performed using synchrotron radiation. The results reveal an energy resolutio no f190 meV and a lateral resolution (edge resolution) o…
The Training of Physical-Education Teachers in France and China: A Comparative Analysis of Curricula and Attitudes
2005
This study in comparative physical education examines the curricula followed by physical-education teachers in China and France. It explores how theories of physical education and sport in each country have developed out of specific political, cultural and educational contexts, yet resulted in strong similarities in terms of the priority given to training programs. Nonetheless, it can be seen that the two curricula reflect genuinely divergent concepts of physical education influencing both theory and practice. The attitudes of Chinese and French teacher-trainers towards physical education and sport are shown to display significant ideological differences with regard to the meaning and educa…
