Modelling aerosol transport and virus exposure with numerical simulations in relation to SARS-CoV-2 transmission by inhalation indoors

We provide research findings on the physics of aerosol and droplet dispersion relevant to the hypothesized aerosol transmission of SARS-CoV-2 during the current pandemic. We utilize physics-based modeling at different levels of complexity, along with previous literature on coronaviruses, to investigate the possibility of airborne transmission. The previous literature, our 0D-3D simulations by various physics-based models, and theoretical calculations, indicate that the typical size range of speech and cough originated droplets (dPeer reviewe

Variation of Supports for Verse Inscriptions in Roman Greece

The material for this paper is provided by my research project on ca. 1,500 verse inscriptions from imperial times between the Emperor Augustus and the end of the 6th century A.D., from the area of modern Greece. Setting aside around 20 hymns and oracles and concentrating on the more certain cases of surviving monuments, where the support type can be verified more or less plausibly, the results are as follows. In sepulchral epigrams, the largest class, there are nearly 20 different types of supports, of which the stele and the plate are the most usual ones; northern Greece seems to favour sarcophagi and grave altars. In contrast, honorific epigrams have more often been cut on bases or herms, the latter being characteristic of Attica. As regards dedicatory epigrams, however, the supports are disturbingly variable. The majority of cases are represented by bases of various types, followed by stelai, mosaics (usually Christian), altars and plates, but natural rocks and many other supports are also found. Finally, building epigrams are too rare for any clear patterns for their supports to be drawn out. It must be remembered that many support types overlap with each other in the various inscriptional classes mentioned above. Only in some cases can the monument type corroborate the interpretation of a fragmentary epigram.A few of the epigrams are illustrated with a photo, the Greek text and an English translation.La matière de cet article m’a été offerte par mon projet de recherche sur les presque 1500 inscriptions métriques d’époque impériale, entre le règne d’Auguste et la fin du VIe siècle ap. J.-C., provenant du territoire de la Grèce moderne. Une fois mis à part une vingtaine d'hymnes et d’oracles, l'étude des cas les plus certains de monuments conservés où le type de support peut être vérifié de manière assez plausible donne les résultats suivants. Pour les épigrammes funéraires, qui forment la catégorie la plus importante, il y a presque 20 types de supports différents et les plus fréquents sont la stèle et la plaque ; au Nord de la Grèce, on semble privilégier les sarcophages et les autels funéraires. En revanche, les épigrammes honorifiques ont le plus souvent été gravées sur des bases ou des hermès, ce dernier type de monument étant caractéristique de l’Attique. En ce qui concerne les épigrammes dédicatoires, les supports sont extrêmement variables. Les bases de différents types constituent la majorité des cas, suivies des stèles, des mosaïques (généralement chrétiennes), des autels et des plaques, mais aussi de rochers naturels et de nombreux autres supports. Finalement, les « épigrammes architecturales » sont trop peu nombreuses pour qu’on puisse tracer des tendances claires concernant leurs supports.Il faut se rappeler qu'un même type de support peut correspondre à différentes catégories d’inscription. Le type de monument ne peut donc corroborer l'interprétation d’une épigramme fragmentaire que dans certains cas.Quelques-unes des épigrammes sont illustrées avec une photo, et présentées avec texte grec et traduction anglaise

Chapter 5. Two Early Christian inscriptions from Eleusis

In what follows the last inedita for a corpus of Attic texts from the Post-Herulian and Early Christian period, i.e. dating from around AD 267 to 600, will be presented prior to a publication of a separate supplement to the post-classical Kirchnerian Inscriptiones Graecae. A fair number of 12 Late Antique inscriptions from Eleusis have been published so far As many as five of them have not been located since their edition by F. Lenormant in 1862. As far as published documents are concerned, f..

Division of Verses in the Late Antique Epigrams of Greece

The article is concerned with the problem of distribution of verses in ca. 200 late (late 3rd to early 6th century A.D.) verse inscriptions from the area of modern Greece. The private funerary epigram is the best attested type, although there are dedicatory, honorary and building epigrams. Around 30 too fragmentary objects fall out. Earlier phases of distribution of verses had to be ignored.Peer reviewe
