Sulla fortuna di «Misero pargoletto»: materiali e ipotesi
2020
The aria "Misero pargoletto", sung by Timante in the third act of Pietro Metastasio's "Demofoonte", enjoyed exceptional fortune throughout the eighteenth century. The text was set tu music dozens of times not only as part of the opera it belongs to, but also as an independent piece. This essay discusses the judgements expressed on "Misero pargoletto" by several men of letters and theorists, examines some buffo parodies of the aria that demonstrate its wide notoriety, and formulates some hypotheses about the reasons for such a great success, which can be partially justified by the new conception of fatherood that emerged in the so-called Age of Sensibility.
Sexual dimorphism in primates: Where are we and where do we go from here?
1986
There are currently several debates taking place in palaeoanthropological circles in which the issue of sexual dimorphism is crucial. During the 60th Jubilee of the discovery of the TaungAustralopithecus skull, the authors concurred that much of the debate was due to differences in perception concerning dimorphism, and it was suggested that a study session dealing principally with sexual dimorphism in Primates should be organised with a view to determining what, if anything, could be observed in extant primates that might be utilised for determining the existence of dimorphism in fossil species. An advertisement was placed in the Journal of Human Evolution, calling for papers. Response was …
On the hidden significance of differing micro-sites on tree-ring based climate reconstructions
2015
Tree-ring chronologies are commonly extended back in time by combining samples from living trees with relict material preserved in man-made structures or natural archives (e.g. lakes). Although spatially close, these natural archives and living-tree-sites often comprise different micro-climates. Inhomogeneous growth conditions among these habitats, which may yield offsets in growth-rates, require caution in data processing. Here we assess species-specific growth dynamics in two micro-habitats and their potential effects on long chronologies by combining tree-ring data from different living-tree-sites with an âartificialâ subfossil dataset. Well replicated (nâ>â80) Norway spruce (…
Ventastega curonica and the origin of tetrapod morphology.
2008
The gap in our understanding of the evolutionary transition from fish to tetrapod is beginning to close thanks to the discovery of new intermediate forms such as Tiktaalik roseae. Here we narrow it further by presenting the skull, exceptionally preserved braincase, shoulder girdle and partial pelvis of Ventastega curonica from the Late Devonian of Latvia, a transitional intermediate form between the 'elpistostegids' Panderichthys and Tiktaalik and the Devonian tetrapods (limbed vertebrates) Acanthostega and Ichthyostega. Ventastega is the most primitive Devonian tetrapod represented by extensive remains, and casts light on a part of the phylogeny otherwise only represented by fragmentary ta…
Central dislocation of the jaw-joint into the middle cranial fossa
1981
Summary The authors' case of central dislocation of the jaw-joint is used to discuss the incidence, mechanism of causation and the problems of clinical diagnosis, and the possible lines of treatment are listed. The management of the central dislocation in our case consisted of surgical reduction of the articular process by means of traction with hooked retractors over a fulcrum in the molar region.
An assessment of energy vulnerability in Small Island Developing States
2020
Abstract Small Island Developing States (SIDS) suffer from several structural characteristics that jeopardize their ability to achieve a sustainable energy future. Their reliance on imported fossil fuels exacerbates their exposure to external threats on international energy markets. Their energy systems are also exposed to internal disturbances that disrupt the proper production, transmission and distribution of energy. The aim of this paper is to investigate the extent to which island energy systems are vulnerable to shocks and internal dysfunctions over which they have no control. For this purpose, we build a composite index of energy vulnerability using the Multi-Layer Benefit-of-the-Dou…
Syphilis 2001 a palaeopathological reappraisal
2002
The origin and subsequent spread of the treponematoses, especially that of venereal syphilis, has been the subject of considerable scientific attention. Various theories were put forth and palaeopathological specimens were used for their validation in recent times. One influential contribution was the paper by Baker & Armelagos in 1988. Numerous new findings and results on both sides of the Atlantic call for a new evaluation of the available osseous material. A review of the recent literature leads to the suggestion of a worldwide distribution of non-venereal treponemal disease since the emergence of Homo and to a first epidemic outbreak of venereal syphilis in Europe of the late 15th and t…
Optimization and Multicriteria Evaluation of District Heat Production and Storage
2019
Climate change mitigation policy requires reducing dependence on fossil fuels and transition to low carbon energy production in district heating (DH). We study here inclusion of two kinds of renewable energy to a CHP based DH system in Finland: solar heat and ground source heat. In addition, we apply heat storages to balance the gap between production and fluctuating demand. The optimal operation of the extended systems is determined by a simulation and optimization model to minimize the operating costs. We evaluate the different possible extensions in terms of multiple economic, technical and environmental criteria using Stochastic Multicriteria Acceptability Analysis (SMAA). The results s…
First record of Anisian deposits in the Betic External Zone of southern Spain and its paleogeographical implications
2023
In the External Zones of the Betic Cordillera (S Spain), upper Muschelkalk (Ladinian) facies have been known for decades; however, so far there is no stratigraphic record of Anisian deposits. In the present study, new biostratigraphic data from a carbonate succession in the easternmost Subbetic domain reveal a Pelsonian-Illyrian (Anisian) age. The nautiloids Germanonautilus salinarius and Germanonautilus saharonicus are documented for the first time in the Iberian Peninsula, and together with the brachiopod Tetractinella trigonella and the bivalves Neoschizodus orbicularis and Myophoria vulgaris they represent marker fossils of Anisian deposits previously described from many other basins, b…
Hermé (Seine-et-Marne), Carrière SPM-Synéos d'Hermé : Tranche 6 des diagnostics archéologiques : rapport de diagnostic
2022
L’opération archéologique menée à Hermé, carrière Synéos (SPM) - tranche 6 des diagnostics archéologiques a permis de mettre au jour des occupations diachroniques néolithique et protohistorique.Ce diagnostic s’est déroulé sur deux parcelles distinctes pour une surface globale de 102 922 m2, une première au lieudit le Château Duduit et la seconde au lieudit La Patûre aux Bœufs.Sur l’emprise du Château Duduit nous avons mis au jour un petit amas de vingt-cinq pièces lithiques daté du Néolithique. Le diagnostic de 2022 a permis de mettre au jour une seule chaîne opératoire (débitage d’éclats par percussion dure) réalisée à partir de matériaux locaux pour la fabrication d’outils tels que les ra…
