Timbrel vaults in Sicily: analysis of a little-known construction technique

2016

La ricerca di alternative al legno per la realizzazione di orizzontamenti ha condotto ad approfondimenti e sperimentazioni sulle strutture voltate, con risultati di grande originalità in grado di coniugare economia e leggerezza senza perdere in sicurezza; vengono qui analizzate le volte siciliane costituite da più fogli di mattoni sottili uniti con gesso (volte realine secondo la definizione locale). Già ampiamente documentata nella Spagna tardo-medievale, la tecnica venne introdotta saltuariamente in Sicilia a partire dalla fine del XV secolo, ed assunse un ruolo importante dalla metà del XVIII. Attraverso l’analisi diretta e delle documentazioni relative ai maggiori cantieri e dai prezzia…

Homicide with post mortem dismemberment of the victim with previous amputation of right lower limb: Case report and review of the literature

2018

The dismemberment of a corpse is comparatively rare in forensic medicine and usually performed with different types of sharp tools. The victim is always the victim of a homicide. Dismemberment usually occurs where the killing took place without prior planning by the perpetrator. We report a case of homicide with post mortem mutilation of the victim’s body with previous amputation of right lower limb in which the perpetrator was not identified. At autopsy, several fractures were detected on the cranial vault, and the cause of death was due to skull and brain injuries from multiple blunt force traumas.

Debonding Phenomena in CFRP Strengthened Calcarenite Masonry Walls and Vaults

2009

In this paper the results of an experimental investigation on full-scale reinforced masonry elements like vaults and walls are presented. The masonry type is constituted by calcarenite ashlars and bed joint mortar and the reinforcement is constituted by Carbon Fibre Reinforced Polymer (CFRP) strips. Preliminary experimental results obtained in a previous research by the authors on the local behaviour at the interface CFRP-calcarenite are summarized. Tests with controlled displacement are carried out on out-of-plane loaded walls and cylindrical vaults loaded at a quarter of the span. Results of tests carried out before and after the application of the reinforcement made it possible to evalu…

Chronic idiopathic hyperphosphatasia with unusual dental findings: a case report

2012

Chronic idiopathic hyperphosphatasia(CIH) or juvenile Paget disease is believed to be a distinct disease characterized by an increase in the serum alkaline phosphatase, cortical thickening and bowing of the long bones, especially the femora. It is a rare autosomal recessive bone disorder, with excessive bone resorption and bone formation. Skeletal malformations in the legs may cause problems in walking and may eventually result in short stature. The radiographic appearances include widening of the diaphyses, vertebral osteoporosis, acetabular protrusion, and thickening of the skull vault. Intensive bisphosphonate treatment prevented the development of deformity and disability but there is n…

CT and MR Imaging of Lesions of Skull Base and Cranial Vault

1989

The importance of CT in examinations of the skull base, including its role in the planning of operative or radiation therapy, has long been recognized (Liliequist and Forsell 1976; Bradac et al. 1977 a, b; 1978 a, b; Hammerschlag et al. 1977; Caille et al. 1977; Lohkamp et al. 1977; Huk and Schiefer 1978; Becker et al. 1978; Weinstein et al. 1978). In the present chapter we shall review the capabilities and limitations of this modality in the diagnosis of diseases involving the bony skull base and cranial vault. A more detailed discussion of specific tumor types may be found under the appropriate headings elsewhere in the book.

Combined surgical and prosthetic approach for rehabilitation of frontonasal defect using custom made titanium implant: a case report

2011

Cranial vault deformities as a sequelae to trauma may be as high as 70%. The basic indications for cranioplasty are improvement of disfigured aesthetics and to provide protection to the intra-cranial contents. The possibility of producing custom-made implants opened a new era in the reconstructive surgery of the craniofacial deformities. The outcome of craniofacial bone reconstruction is thought to be dependent on surgical skills, quality of adjacent soft tissues, size and location of the bone defect and choice of repair method. The use of autologous bone for craniofacial reconstruction may be restricted due to limited amounts of donor bone. Combined surgical and prosthetic rehabilitation o…

Proteomic analysis reveals a role for Bcl2-associated athanogene 3 and major vault protein in resistance to apoptosis in senescent cells by regulatin…

2014

Senescence is a prominent solid tumor response to therapy in which cells avoid apoptosis and instead enter into prolonged cell cycle arrest. We applied a quantitative proteomics screen to identify signals that lead to therapy-induced senescence and discovered that Bcl2-associated athanogene 3 (Bag3) is up-regulated after adriamycin treatment in MCF7 cells. Bag3 is a member of the BAG family of co-chaperones that interacts with Hsp70. Bag3 also regulates major cell-signaling pathways. Mass spectrometry analysis of the Bag3 Complex revealed a novel interaction between Bag3 and Major Vault Protein (MVP). Silencing of Bag3 or MVP shifts the cellular response to adriamycin to favor apoptosis. We…

Case Study of the Structural Behavior of a Catalan Bricks Masonry Vault

2015

Catalan vaults are a peculiar type of low thickness vaulted brick masonry structure. Knowledge of load-deflection response and load bearing capacity are important aspects to consider with the aim of preserving these structural members as part of the cultural heritage. In order to investigate these aspects, complete knowledge of the constituent materials and geometry (dimension, thickness, constructive section) is necessary in such a way as to predict the load-deflection response and the effective load-carrying capacity; the latter can be determined utilizing simplified models (limit analysis) or by means of a numerical analysis (finite element method). With this aim, the structural behaviou…

The dammuso: constructive characters of the traditional stone buildings of the isle of Pantelleria (Sicily)

2019

Pantelleria, a volcanic island between Tunisia and Sicily, is characterized by a highly windy territory constantly hit by the sun. This harsh environment forced the inhabitants to build in an extremely effective way against the natural elements. This paper investigates constructive technologies, local materials, and phases of construction of the traditional rural houses, the dammuso, a Sicilian word meaning “vaulted-building”. It is a traditional passive cooling building characterized by a cubical shape covered by a vaulted-roof. This typology can be found almost everywhere in the isle, both old and pretty new, as the only one permitted. The minimum configuration unit is a cube made of bear…
