Dental health in adults and subadults from the 16th-century plague cemetery of Alghero (Sardinia, Italy)

Objective: The aim of this study is to examine a set of dental health indicators, including caries, periodontal disease, abscesses, ante-mortem tooth loss, calculus, and tooth wear of a 16th-century population from the city of Alghero, Sardinia (Italy), in order to evaluate the state of dental health and the diet. Design: The cemetery is referable to the plague outbreak that ravaged the city in 1582-1583. A total of 160 individuals (81 adults and 79 subadults) were suitable for dental examination. Results: The oral conditions of the urban population of Alghero are characterised by high frequency of carious lesions, periodontal disease, ante mortem tooth loss, and calculus, but a low prevalence of abscesses and moderate tooth wear are recorded. In general, no statistically significant sexual differences are observed, suggesting a uniform scenario for diet access and oral health. The subadult subsample shows moderate rates of caries and is affected by calculus. The results suggest that the diet was rich in soft and refined food, with a prevalence of carbohydrates and cariogenic aliments; the effects of the diet are associated with a lack of oral hygiene. Conclusions: The patterns of dental health observed in the Alghero population fit with the data observed in other Modern Age samples, reflecting increased prevalence of dentoalveolar diseases resulting from a less abrasive diet and an increase in carbohydrate consumption, as documented during the transition from the Middle Ages to the Modern period

Castelsardo e l'archeologia dei Doria: campagna di scavo 2007

Resoconto della terza campagna di scavo che si è svolta nei giorni dal 30 luglio al 2 settembre 2007 nell'area degli Spalti Manganella di Castelsardo. L'operazione segue gli interventi di scavo del biennio 2005-2006 e si inserisce nell'ambito del progetto di valorizzazione delle città regie della Sardegna, del restauro delle fortificazioni medievali e del ripristino di ampi tratti del percorso di sentinella adiacenti alle mura difensive sul lato mare

Campagna di ricognizione archeologica dei villaggi medievali abbandonati di Chiaramonti

Si traccia la descrizione del progetto di ricerca "I villaggi medievali abbandonati nel territorio comunale di Chiaramonti", avviato nel mesi di marzo 2007 dall'Autore. Il progetto ha come fine l'identificazione sul terreno delle aree occupate dai resti dei numerosi villaggi medievali abbandonati, ubicati nell'attuale territorio comunale di Chiaramonti attraverso l'utilizzo delle metodologie proprie all'indagine storica e archeologica: analisi delle fonti documentarie e archivistiche, ricognizione di superficie volta al riconoscimento e alla perimetrazione delle aree interessate da emergenze archeologiche, elaborazione di documentazione e cartografia mediante le più moderne tecnologie informatiche (Databases, GIS, CAD)

Advanced Technologies for Green Hydrogen Production

Hydrogen represents a versatile fuel that has found usage in several sectors, such as automotive, aerospace, chemical industries, etc. Today, fossil fuels, due to their high hydrogen content, are the dominant source of hydrogen production and steam methane reforming is the most widely used technology: over 95% of the current production of hydrogen is based on the reforming of fossil fuels. However, in the near future, in order to reduce fossil CO2 emissions, hydrogen production is expected to gradually shift toward green solutions

Preliminary archeological site survey by UAV-borne lidar. A case study

Preliminary analysis of an archaeological site requires the acquisition of information by several diverse diagnostic techniques. Remote sensing plays an important role especially in spatially ex-tended and not easily accessible sites for the purposes of preventive and rescue archaeology, landscape archaeology, and intervention planning. In this paper, we present a case study of a de-tailed topographic survey based on a light detection and ranging (LiDAR) sensor carried by an unmanned aerial vehicle (UAV; also known as drone). The high-resolution digital terrain model, obtained from the cloud of points automatically labeled as ground, was searched exhaustively by an expert operator looking for entrances to prehistoric hypogea. The study documents the useful-ness of such a technique to reveal anthropogenic structures hidden by vegetation and perform fast topographic documentation of the ground surface

The role of age, sex, anthropometry, and body composition as determinants of physical fitness in nonobese children aged 6\u201312

PURPOSE: The determinants of physical fitness in children have been given limited attention. In particular, the relative role of chronological age, sex, anthropometry, and body composition in physical fitness of children has been barely investigated. This cross-sectional study investigated determinants of physical fitness using a set of predictive variables including, in addition to chronological age and sex, a large panel of anthropometric measurements as well as body composition. The study was carried out in a convenience sample of children aged 6\u201312 participating in a summer camp. METHODS: One-hundred-ninety-three children (128 males) fulfilled all requirements and entered analysis. Health-related physical fitness components (speed, muscular power and balance) were explored by means of field tests, namely the 30-m dash test for running speed, the standing long jump and the seated chest pass test for lower limbs and upper body muscular power, respectively, and the flamingo balance test for static balance. Determinants of physical fitness were investigated by regression analysis using chronological age, sex, anthropometry, and body composition in a hierarchical approach. To minimize the expected effect of collinearity in predictor variables, an original statistical approach using Random Forests analysis was adopted. RESULTS: Age predicted 45.2%, 43.6%, 35.6% and 25.6%; and sex 9.5%, 10.7%, 6.3% and 2.0% of variance in the 30-m dash, seated chest pass, standing long jump, and flamingo balance test, respectively. Anthropometry and body composition explained a limited or no percentage of variance. The adjusted R2 (root mean square error) was 0.61 (0.31 s), 0.45 (0.32 m), 0.58 (0.15 m) and 0.41 (0.75 logs) for the 30-m dash, seated chest pass, standing long jump, and flamingo balance test, respectively making these models useful when physical fitness tests are not feasible. CONCLUSIONS: We highlighted the respective role of chronological age, sex, anthropometry, and body composition in physical fitness of children in the wide age range 6\u201312 years. Data confirm and expand on previous literature by showing with a strictly conservative statistical approach that chronological age is a main determinant of physical fitness of both boys and girls, sex playing a limited role. The role of anthropometry was even less important, and no role was found for body composition. These findings should be considered when planning/implementing motor development or physical education programs
