The Impact of Grain Size Composition and Organic Matter Content on Magnetic Susceptibility of Anthropogenically Transformed Bottom Sediments, as Exem…

2018

The article presents the results of an analysis of the surface layer of bottom sediments in the naval harbour in Hel. During field work conducted in June 2013, 54 sediment samples were collected. The aim of the study was to examine magnetic susceptibility of harbour sediment as a parameter determining the degree of anthropopressure. As part of laboratory tests, grain size analysis was performed in order to determine organic matter content and magnetic susceptibility of the sediment. The study also measured the impact of environmental factors on fluctuations in the other studied parameters. The results demonstrate increased dynamics of sedimentary environment in the open part of the naval ha…

Geoarchaeological investigations of a prominent quay wall in ancient Corcyra: Implications for harbour development, palaeoenvironmental changes and t…

2018

Abstract In antiquity, the harbour-city of Corcyra (modern: Corfu) was a prevailing naval power in the Mediterranean and had several harbours to host a considerable fleet. Today, these harbours are totally or partly silted and concealed under modern urban infrastructure. Comprehensive geoarchaeological studies were conducted on the northeastern fringe of the Analipsis Peninsula where excavations have revealed the archaeological remains of a massive quay wall (Pierri and Arion sites). These remains are located east of known ancient harbour structures that belong to the Alkinoos Harbour. Our study aimed to reconstruct the palaeoenvironmental setting of the harbour facilities at the Pierri sit…

Per ricostruire la Palazzata seicentesca di Messina

2014

L’idea di aprire la città murata di Messina al suo porto, sostituendo la cortina medievale con un prospetto architettonico, è una sfida politica e militare lanciata dalla città alla Corona di Spagna. Il suo esordio ha precisa origine nel 1556, quando il viceré Juan de Vega e lo scultore architetto Giovannangelo Montorsoli avviano l’uso urbano della banchina portuale con la realizzazione del fonte di Nettuno, ispirata dalla opportunità di “passeggiare” sul molo. Negli ultimi anni del Cinquecento Jacopo Del Duca convince inizialmente gli amministratori ad abbattere le mura per costruire il Palazzo del Banco, poi a trasformare l’intera cortina in un prospetto con unico modello iterato. Nel 162…

Extinct type of human parvovirus B19 persists in tonsillar B cells

2017

Parvovirus B19 (B19V) DNA persists lifelong in human tissues, but the cell type harbouring it remains unclear. We here explore B19V DNA distribution in B, T and monocyte cell lineages of recently excised tonsillar tissues from 77 individuals with an age range of 2–69 years. We show that B19V DNA is most frequent and abundant among B cells, and within them we find a B19V genotype that vanished from circulation >40 years ago. Since re-infection or re-activation are unlikely with this virus type, this finding supports the maintenance of pathogen-specific humoral immune responses as a consequence of B-cell long-term survival rather than continuous replenishment of the memory pool. Moreover, we …

The contribution of archaeological plant remains in tracing the cultural history of Mediterranean trees: The example of the Roman harbour ofNeapolis

2015

In this paper, we present a detailed record of the plant remains recovered on the palaeo-seafloors of Neapolis harbour, spanning ≈700 years, between the 2nd century BC and the 5th century AD, thus intersecting the entire Roman Imperial Age. The site preserved many cultivated or cultivable plant remains, especially from food related trees. This particular feature provided the opportunity to reconstruct the puzzling history of planting them and the Roman economy, especially with respect to food production, the market and to dietary habits. The evidence suggests that Prunus persica, Castanea sativa, Juglans regia and Pinus pinea were locally grown all along the investigated period, testifying …

Logistica e relazioni industriali nell’esperienza comparata: il porto di Rotterdam

2019

The paper analyses the system of industrial relations at the harbour of Rotterdam, with a particular attention to the welfare measures on behalf of workers over 55, more interested by risk of unemployment because of the impact of ICTs on logistics.

Geoarchaeology as a tool to understand ancient navigation in the northern Persian Gulf and the harbour history of Siraf

2020

International audience; Historical texts and archaeological studies attest to the maritime and trade importance of the Persian Gulf since the Sassanid Empires. Nonetheless, there is a paucity of data regarding ancient navigation and the reasons for a shift in m aritim e trade from the western (e.g. Shatt-al-Arab) to eastern (Siraf) Persian Gulf by the Abbasid dynasty. For som e scholars, Siraf was occupied between 360 and 977 CE, after which tim e an earthquake en-trained the dem ise of the city. However, it is unclear when Siraf was founded and how natural navigation conditions changed for ocean-going vessels in harbours of the NW Persian Gulf. To address this knowledge gap, we here presen…
