Turtles on the trash track: loggerhead turtles exposed to floating plastic in the Mediterranean Sea
2019
Loggerhead turtles (Caretta caretta) spend most of their life in large marine areas occupying a variety of habitats where they are exposed to different types of threats. Among these, marine litter is known to pose a risk of entanglement or ingestion. Areas of risk exposure can be identified where the species overlap with litter accumulations, but gathering data on this highly mobile species and marine litter, especially in high sea areas, is challenging. Here we analysed five years of sea turtle and marine litter data collected by a network of research bodies along fixed trans-border transects in the Mediterranean Sea. Ferries were used as observation platforms to gather systematic data on …
El monogramista F.D.V. ¿Frans de Vriendt? A propósito de una Susana y los viejos firmada y fechada en 1543
2017
En este artículo analizamos una pintura flamenca inédita, que representa la escena de Susana y los viejos. Se conserva en una colección particular de Cartagena (Murcia). Está fechada en 1543 y firmada por F.D.V., monograma que plantea la principal incógnita de nuestra investigación. Tales siglas hacen pensar de inmediato en el pintor Frans Floris de Vriendt. En este sentido, los rasgos estilísticos de la obra están próximos al espíritu de este maestro. Sin embargo, diversas cuestiones nos impiden confirmar por el momento tal autoría. En el texto desarrollamos estas hipótesis y definimos la personalidad artística del que denominamos Monogramista F.D.V. In this paper, we analyze an unpublishe…
Network Physiology of Cortico–Muscular Interactions
2020
Skeletal muscle activity is continuously modulated across physiologic states to provide coordination, flexibility and responsiveness to body tasks and external inputs. Despite the central role the muscular system plays in facilitating vital body functions, the network of brain-muscle interactions required to control hundreds of muscles and synchronize their activation in relation to distinct physiologic states has not been investigated. Recent approaches have focused on general associations between individual brain rhythms and muscle activation during movement tasks. However, the specific forms of coupling, the functional network of cortico-muscular coordination, and how network structure a…
Contribución al conocimiento de la flora alóctona abulense (Ávila, España)
2012
Se aportan datos corológicos de catorce plantas vasculares presentes en la provincia de Ávila (España). De ellas, cinco son primeras citas provinciales: Chamaesyce prostrata (Aiton) Small, Conyza sumatrensis (Retz.) E. Walker, Helianthus tuberosus L., Melia azedarach L. y Panicum miliaceum L. El resto de plantas vasculares no son muy conocidas en la zona. Para cada una de ellas se aporta información florística y bibliográfica.SUMMARY: Chorological data concerning fourteen species of invasive vascular plants in Ávila province (Spain) are shown. Among them, we must highlight Chamaesyce prostrata (Aiton) Small, Conyza sumatrensis (Retz.) E. Walker, Helianthus tuberosus L., Melia azedarach L. a…

Notulae to the Italian native vascular flora: 12
2021
In this contribution, new data concerning the distribution of native vascular flora in Italy are presented. It includes new records, confirmations, exclusions, and status changes to the Italian administrative regions. Nomenclatural and distribution updates, published elsewhere, and corrigenda are provided as Suppl. material 1.
Additions to the vascular flora of central Italy. Second contribution
2018
In this paper, new floristic records for 55 taxa for central Italy are reported. In particular, 39 taxa are native and 16 aliens, 9 are new or confirmed to Abruzzo, 1 to Marche, 21 to Molise, 16 to Umbria, 1 is excluded from the flora of Abruzzo, 1 from Molise and 1 from Lazio. Furthermore, new distribution data for 2 rare species in Abruzzo and Molise are reported.
A New Systematic Series of Foil Sections with Parallel Sides
2020
Parallel-sided foil sections are used for centerboards and rudders in sailing dinghy classes and also for struts placed in a fluid flow. The objective of this work is to create a systematic series of parallel-sided sections to be used under different conditions, with an emphasis on the sailing dinghies 470, 420 and Optimist. The loss, and surprisingly the gain, in performance relative to 4-digit NACA sections are also investigated. A 2D Reynolds-averaged Navier&ndash
Monitoring Human Neutrophil Differentiation by Digital Holographic Microscopy
2021
We report on the usefulness of digital holographic microscopy (DHM) for the assessment of human neutrophil differentiation from myeloid cells. The cell and nuclear regions have been designated by image segmentation of the optical phase function, and the changes of the cell nucleus morphology in relation to the whole cell morphology have been examined during the process of granulocytic differentiation into mature neutrophils in PLB-985 cell line. Nucleus phase volume and circularity and the ratios between the nucleus and the cell projected area and volume provide a reliable set of parameters to characterize the maturation process. As control, cell differentiation has been monitored in parall…
La censura nella Francia settecentesca e la figura del colporteur tra realtà e finzione
2015
La censura assume un’importanza fondamentale nella Francia settecentesca se si considera il vistoso aumento dei censori che passa da quarantuno all’inizio del secolo a settantotto alla vigilia della Rivoluzione. Cercando di raggirare i divieti imposti dalla censura, i colporteur ossia i venditori francesi ambulanti di libri eludano la sorveglianza nascondendo sotto il loro mantello sia scritti libertini che libelli politici, vale a dire i libri più amati e contestati dell’epoca, per poi venderli ai clienti piùabbienti. Censorship is of fundamental importance in eighteenth-century France, a fact corroborated by the increase in the number of censors throughout the century: from forty-one in t…
