The role of partial incubation and egg repositioning within the clutch in hatching asynchrony and subsequent effects on breeding success
2019
The main mechanism to achieve hatching asynchrony (HA) for incubating birds is to start heating the eggs before clutch completion. This might be achieved through partial incubation and/or early incubation. Even in the absence of incubation behaviour during the laying phase, clutches still experience a certain degree of asynchrony. Recent studies have shown that eggs located in the centre of the nest receive more heat than peripheral ones during incubation. As eggs receiving more heat would develop faster, we hypothesized that HA should be shorter in nests where eggs were moved homogeneously along the centre–periphery space during incubation than in those nests where eggs repeatedly remained…
Stem cells and oral surgery : a systematic review
2019
Background Considering the structural loss that occurs after surgical procedures for cystic and tumoral pathology, in periodontitis, as well as the maxillary atrophy that determines the rehabilitation with dental implants, it is imperative to find satisfactory solutions. The opportunity provided by the findings in stem cells is a recent introduction in the field of oral surgery, based on the regenerative potential that these cells possess in order to restore defects at different levels of the oral cavity. The aim of this systematic review is to discover the real applications that stem cells may have in our treatments in the near future. Material and methods We made a systematic review of th…
A Post-contentious Turning Point for the Contentious French? Crisis Without Protest in France
2018
International audience; This chapter shows that the ‘contentious French’ may not be that contentious anymore. The economic crisis provides a unique chance to argue that a post-contentious turning point is emerging in spite of a long-standing tradition of protesting. Yet the chapter suggests that this post-contentious turning point is not bringing about acquiescence but opens space for new forms of political participation, especially in connection with resources acquired through employment and educational track. In this case, we find a more extensive engagement in online activism and non-institutional forms of political participation, that is, the two forms of political participation that ar…
Design, Manufacturing, and Strength Test of a 4-post ROPS Fitted on a Very Low-Profile Tractor (TRACLAS Project)
2022
To improve the safety level when agricultural tractors work on slope under canopy, INAIL (the Italian National Institute for Insurance against Accidents at Work) funded a research project, named TRACLAS, devoted to set-up a prototype of low-profile compact tractor, not exceeding 1.60 m overall height, equipped with a 4-post ROPS (RollOver Protective Structure). After the complete set-up of the prototype, some field and lab tests were carried out to compare its performance with those of some comparable tractor models already on the market, used in vineyards, orchards and greenhouses. A basic step of the TRACLAS project was the execution of the strength test of the customized 4-post frame (th…
Development of processes, qualification, and de-risking for the Ariel primary mirror
2022
The work carried out in the Ph.D. program focused on developing the optics design of the Atmospheric Remote-Sensing Infrared Exoplanet Large Survey (Ariel) telescope, an optical/infrared mission of the European Space Agency (ESA), whose primary mirror is an off-axis paraboloid mirror measuring 1.2 · 0.7m. The novelty of the telescope is that both the mirrors and the telescope structure will be made of aluminium, and the primary mirror will be made of bare aluminium without a thick hard coating. The choice is mainly due to the thermo-mechanical properties of the material, and the usage of the same material for the whole structure will allow better heat exchange between the mirror and the opt…
The eio proposal for a directive and mafia trials: Striving for balance between efficiency and procedural guarantees
2013
PD EIO could mark a turning point in the development of “European criminal procedure.” The Proposal will obtain evidence in cross-border cases and is particularly suitable for investigations on the subject of international organized crime. From the long gestation period and the contents of the Proposal emerges, however, the difficulty of making a balance between the investigation of crimes and the guarantees of the individuals involved. The use of collected of evidence from different legal systems is often an overly neglected aspect. Doubt surrounds the regulation of banking instruments, the rules on wiretapping, and all provisions for undercover investigations.
Raw material variability as archaeological tools: Preliminary results from a geochemical study of the basalt vessel workshop at Iron Age Tel Hazor, I…
2016
The discovery of a basalt vessel workshop at Tel Hazor, one of the most important Iron Age sites in the Near East, marks a turning point in our understanding of stone artifact production and distribution during the1st millennium BCE. It offers a rare opportunity to characterize ancient raw material sources, production sites, and study production, trade and distribution systems. The basalt vessel workshop, the only one of its kind in the Levant, produced large quantities of bowl preforms and production waste. To better understand the production and distribution systems behind this specialized production center, in 2011 we initiated a focused geochemical project that concentrated on the produ…
Is there an environmental Kuznets curve for Spain? Fresh evidence from old data
2012
Abstract The information content of the environmental Kuznets curve (EKC) is subject to change over time and all the empirical modeling work that does not take into account the possible variations and instabilities may fail to explain the variations in the per-capita CO2 and per-capita income relationship. In this paper we consider the possibility that a linear cointegrated regression model with multiple structural changes would provide a better empirical description of the Spanish EKC during the period 1857–2007. Our methodology is based on instability tests recently proposed in Kejriwal and Perron (2008, 2010) as well as on cointegration tests developed in Arai and Kurozumi (2007) and Kej…
Popular Music and the Anthropocene
2020
International audience; We are at a major turning point, probably irreversible for thousands of years. Despite the continued use of slogans like ‘Save the Planet’, it is living beings, more than the Earth (which has already seen many upheavals) who are threatened with extinction. Although the proponents of the term Anthropocene agree that human activities have become a force that is influencing the geological course of the Earth, and stratigraphers are already finding traces of that process in rocks and sediments (Zalasiewicz 2010), we can however identify two contrasting narratives about the Anthropocene.
Riconfigurazioni identitarie nei contesti urbani degradati: discontinuità e riflessività
2019
Che rilevanza ha il contesto territoriale nei percorsi biografici dei residenti? Che significato assumono in un determinato territorio i turning point, le discontinuità, gli eventi imprevisti che si verificano nella vita degli individui? E ancora, perché soggetti che nascono e vivono in ambienti degradati economicamente e culturalmente riescono a cambiare il corso della propria vita che sembrerebbe ripetersi con modalità abituali per altri consociati (familiari o residenti) con esiti di degrado personale o marginalità sociale? Nell’articolo, attraverso i dati di una ricerca si svilupperà la relazione che intercorre tra discontinuità biografiche e riflessività che nei turning point influenza…
