The palaeontological virtual collection of the University of Valencia’s Natural History Museum: a new tool for palaeontological heritage outreach
2019
The rise of new digitalization technologies is changing the way to access to the fossil collections for palaeontology outreach, providing new tools to preserve our important palaeontological heritage. In this sense, museums and palaeontological institutions,aware of the advantages of applying these new technologies for the accomplishment of their functions, have started to develop their own online repositories to facilitate the access to the most representative fossil of their collections. Following this trend, the aim of this work is to present the creation of the new “Virtual 3D Collection” of the University of Valencia’s Natural History Museum, showing, as an example, the “Ichnofossil Co…

Autonomy and Connectedness among Italian Emerging Adults: Their Relations with Psychological Well-Being
2012
Emerging adulthood is a distinct period demographically, subjectively, and in terms of identity explorations characterized by profound role changes across multiple life domains (Arnett, 2001). According to many authors (Aquilino, 2006; Fingerman, 2000), autonomy and relatedness both must be fulfilled for psychological growth and well-being not only during adolescence, but may be even more necessary as an adolescent makes the transition into emerging adulthood and then into adulthood. In this perspective, the autonomous-relational self is suggested to be a healthy synthesis of autonomy and relatedness (Kagitcibasi, 1996, 2007). Given that issues of autonomy and connectedness appear to be maj…
Autonomy and Relatedness in Adolescence and Emerging Adulthood: Relationships with Parental Support and Psychological Distress
2014
Autonomy and relatedness are fundamental needs both in adolescence and in emerging adulthood which are affected by parental support and are linked to children’s psychological distress. The study investigated autonomy and relatedness in late adolescents and emerging adults living in Italy, analyzing the relationships with perceived parental support and psychological distress. Self-report data were collected from a sample of 325 Caucasian adolescents and emerging adults (males = 41 %) ranging in age from 17 to 26 years and living in Sicily (southern Italy). Results showed that: (a) both autonomy and relatedness were positively predicted by parental support to these needs, (b) perceived suppor…
Constraints on bosonic dark matter from ultralow-field nuclear magnetic resonance
2019
The nature of dark matter, the invisible substance making up over $80\%$ of the matter in the Universe, is one of the most fundamental mysteries of modern physics. Ultralight bosons such as axions, axion-like particles or dark photons could make up most of the dark matter. Couplings between such bosons and nuclear spins may enable their direct detection via nuclear magnetic resonance (NMR) spectroscopy: as nuclear spins move through the galactic dark-matter halo, they couple to dark-matter and behave as if they were in an oscillating magnetic field, generating a dark-matter-driven NMR signal. As part of the Cosmic Axion Spin Precession Experiment (CASPEr), an NMR-based dark-matter search, w…
Noninvasive respiratory support in the hypoxaemic peri-operative/periprocedural patient: A joint ESA/ESICM guideline.
2020
Hypoxaemia is a potential life-threatening yet common complication in the peri-operative and periprocedural patient (e.g. during an invasive procedure at risk of deterioration of gas exchange, such as bronchoscopy). The European Society of Anaesthesiology (ESA) and the European Society of Intensive Care Medicine (ESICM) developed guidelines for the use of noninvasive respiratory support techniques in the hypoxaemic patient in the peri-operative and periprocedural period. The panel outlined five clinical questions regarding treatment with noninvasive respiratory support techniques [conventional oxygen therapy (COT), high flow nasal cannula, noninvasive positive pressure ventilation (NIPPV) a…
A Recent Advancement: Casing while Drilling – A Viable Alternative to Conventional Drilling
2021
Mankind’s increased requirement for and dependence on energy resources, including the resources resulting from discovery and development of new hydrocarbon commercial reservoirs involves the use of new technologies such as optimization of the drilling process by reducing the non-productive time, the costs and the risks. Casing while drilling involves elimination of classical drilling string by using the casing string both for transmission to the bit of the mechanical energy and for circulation of drilling fluid into the well. Casing while drilling, constantly improving over time, has proven an efficient method to reduce risks, especially those related to the presence of a conventional…
Phonon superradiance and phonon laser effect in nanomagnets
2004
We show that the theory of spin-phonon processes in paramagnetic solids must take into account the coherent generation of phonons by the magnetic centers. This effect should drastically enhance spin-phonon rates in nanoscale paramagnets and in crystals of molecular nanomagnets.
Ten millennia of hepatitis B virus evolution
2021
Hepatitis B virus (HBV) has been infecting humans for millennia and remains a global health problem, but its past diversity and dispersal routes are largely unknown. We generated HBV genomic data from 137 Eurasians and Native Americans dated between ~10,500 and ~400 years ago. We date the most recent common ancestor of all HBV lineages to between ~20,000 and 12,000 years ago, with the virus present in European and South American hunter-gatherers during the early Holocene. After the European Neolithic transition, Mesolithic HBV strains were replaced by a lineage likely disseminated by early farmers that prevailed throughout western Eurasia for ~4000 years, declining around the end of the 2nd…
