Genesi geometrica delle volte centriche

1996

Un'analisi completa degli organismi voltati comporta lo studio delle molteplici componenti necessarie alla loro definizione: configurazione geometrica, sistema costruttivo, area storico-geografica di appartenenza, interpretazioni Stilistiche. L’obiettivo di questo studio è indirizzato all' analisi delle volte continue su pianta centrica definibili attraverso le leggi della geometria euclidea. L’indagine si pone all'interno dei confini relativi alla loro configurazione geometrica e il criterio adottato, svincolato da classificazioni di carattere tipologico o stilistico, propone l'identificazione di famiglie geometriche in base alla figura del poligono di base dell'impianto. Si può identifica…

A comprehensive analysis of vaulted bodies involves the study of the multiple components necessary for their definition: geometric configuration construction system historical-geographical area of belonging interpretations Stylistic. The objective of this study is directed to the 'analysis of continuous vaults on a centric plan definable through the laws of Euclidean geometry. The investigation arises within the boundaries related to their geometric configuration and the criterion adopted freed from typological or stylistic classifications proposes the identification of geometric families based on the figure of the basic polygon of the plant. An ordering process can be identified to explain the compositional process of curved-roofed central plants: that is the elaboration of a series of theoretical models developed according to an abacus referring to the basic geometries of the triangle square and pentagon is possible. It is not intended to impose a classification but to propose a study tool that thanks to a few simple compositional rules develops a very large number of configurationthe question remains as to why only a part has been used for the realization of vaulted covered centric buildings but this presumes considerations of a historical formal and constructive nature extraneous to this discussion.Settore ICAR/17 - Disegno

The Postmedieval Latvian Oral Microbiome in the Context of Modern Dental Calculus and Modern Dental Plaque Microbial Profiles

2021

Recent advantages in paleomicrobiology have provided an opportunity to investigate the composition of ancient microbial ecologies. Here, using metagenome analysis, we investigated the microbial profiles of historic dental calculus retrieved from archaeological human remains from postmedieval Latvia dated 16–17th century AD and examined the associations of oral taxa and microbial diversity with specific characteristics. We evaluated the preservation of human oral microbiome patterns in historic samples and compared the microbial composition of historic dental calculus, modern human dental plaque, modern human dental calculus samples and burial soil microbiota. Overall, the results showed tha…

Low Prevalence of Lactase Persistence in Bronze Age Europe Indicates Ongoing Strong Selection over the Last 3,000 Years

2020

Lactase persistence (LP), the continued expression of lactase into adulthood, is the most strongly selected single gene trait over the last 10,000 years inmultiple human populations. It has been posited that the primary allele causing LP among Eurasians, rs4988235-A [1], only rose to appreciable frequencies during the Bronze and Iron Ages [2, 3], long after humans started consuming milk from domesticated animals. This rapid rise has been attributed to an influx of people from the Pontic-Caspian steppe that began around 5,000 years ago [4, 5]. We investigate the spatiotemporal spread of LP through an analysis of 14 warriors from the Tollense Bronze Age battlefield in northern Germany ( 3,20…

Bone diagenesis of archaeological human remains from Apulia (Italy) investigated by ATR-FTIR and XRF spectroscopy

2023

The analysis of the organic and mineral content of biological samples allows to define post-mortem alterations and the preservation status of ancient human remains. Here, we report a physical-chemical characterization of bone specimens from some skeletal remains found in Apulia (Italy) dating back to the prehistoric, classic-hellenistic, and medieval periods. Specific infrared band ratios from Attenuated Total Reflectance-Fourier Transform InfraRed and X-ray fluorescence spectroscopies were considered to evaluate the extent of the diagenetic process and the elemental composition of bone.Physical-chemical post-mortem transformations were related to the soil composition and specificity of tis…

Assessing use and suitability of scanning electron microscopy in the analysis of micro remains in dental calculus

2014

AbstractDental calculus is increasingly recognized as a major reservoir of dietary information. Palaeodietary studies using plant and animal micro remains (e.g. phytoliths, pollen, sponge spicules, and starch grains) trapped in calculus have the potential to revise our knowledge of the dietary role of plants in past populations. The conventional methods used to isolate and identify these micro remains rely on removing them from their microenvironment in the calculus, thus the microenvironment that traps and preserves micro remains is not understood. By using scanning electron microscopy and energy-dispersive X-ray spectroscopy (SEM–EDX) on modern chimpanzee calculus from the Taï Forest, Côt…

Antiguas excavaciones, nuevas respuestas. El yacimiento epimagdaleniense de la Cova del Clot de l'Hospital (Roquetes, Baix Ebre)

2015

El objetivo de este trabajo ha sido estudiar los materiales obtenidos con las excavaciones de Francesc Esteve Gálvez en la Cova del Clot de l’Hospital (Bajo Ebro), yacimiento de finales del Pleistoceno-inicios del Holoceno, descubierto por él mismo el año 1945. La representación de raspadores, truncaduras, buriles y laminitas de dorso, entre otros tipos, permite atribuirlo al Epimagdaleniense, atribución corroborada por dos fechas radiocarbónicas sobre huesos de fauna: 11.115 y 10.045 BP. De esta forma, este yacimiento se suma a un numeroso conjunto de yacimientos del período citado, conocidos en las provincias de Tarragona y de Castellón de la Plana. Así mismo, el estudio de los restos fau…

Women’s empowerment and child mortality: the case of Bangladesh

2018

Bangladesh is the Southern Asian country that has been experiencing the highest absolute decline in the Under Five Mortality Rate in the past 15 years. This paper focuses on the importance of women’s education and empowerment variables in explaining this extraordinary result. We use a twolevel multilevel logistic regression to take into account the great differences among territorial communities in terms of child mortality reduction. It emerges that the importance of woman’s empowerment - measured as individual and as mother - remains relevant even when the context is considered. A sensitivity analysis has been conducted to test the relevance of different indicators of female empowerment.

"Nel più fulgido scenario di colori” Goethe e la scoperta del paradiso a Napoli

2017

Dopo avere visitato Roma, nel febbraio del 1787, J.W. Goethe giungeva a Napoli dove: «l’atmosfera si faceva sempre più pura, ormai ci trovavamo in un’altra terra». Nella seconda metà del Settecento, in Europa il poeta di Francoforte rappresentava certamente il massimo fra i divulgatori del mito del paradiso a Napoli e in Campania, ma anche in Sicilia, e dunque nel Meridione d’Italia, sia per la loro rigogliosa e sempre verde natura sia per l’abbondanza delle loro antichità classiche. A Roma Goethe aveva pregustato i frutti di questo paradiso, ma è solo visitando Napoli e il suo territorio che realizza di essere in un altro mondo, totalmente diverso dai paesi del Nord. Il presente saggio ha …

A hidden species becoming visible : biogeography and ecology of Rhynchotalona latens (Cladocera, Anomopoda, Chydoridae)

2019

A long hidden chydorid (Chydoridae, Cladocera) taxon, first found as fossil specimens and recently redefined as Rhynchotalona latens (Sarmaja-Korjonen et al., Hydrobiologia 436: 165-169, 2000) is investigated for its biogeography and ecology. Late Holocene sediment sequence from Lake Sylvilampi, NE Finnish Lapland, and R. latens spatial distribution in relation to limno-climatic attributes in Finland were examined. Principal component analyses of fossil cladoceran communities showed that R. latens is mostly affiliated with Alonella excisa-Alonopsis elongata-Alonella nana species pool. Generalized linear modeling of R. latens responses to limno-climatic variation indicated that it prefers ac…
