Three hundred years of death : the Egyptian funerary industry in the Ptolemaic period /
No full text"In Three Thousand Years of Death, The Egyptian Funerary Industry in the Ptolemaic Period, Maria Cannata provides a detailed survey of the organisation of the necropolises and the funerary workers, as well as their role in the practical aspects of the mummification, funeral, burial, and mortuary cult of the deceased, in Ptolemaic Egypt (332-30 BC). The author gathers together and synthesises hundreds of the original textual sources, as well as the relevant archaeological sources, on the organisation of the funerary industry and its practitioners, revealing important regional and chronological variations overlooked in studies focusing on a limited geographical area, a shorter timeframe, or a smaller group of documents".Includes bibliographical references and index."In Three Thousand Years of Death, The Egyptian Funerary Industry in the Ptolemaic Period, Maria Cannata provides a detailed survey of the organisation of the necropolises and the funerary workers, as well as their role in the practical aspects of the mummification, funeral, burial, and mortuary cult of the deceased, in Ptolemaic Egypt (332-30 BC).

Comparison of one-dimensional and two-dimensional GRASS GIS models for flood mapping.
No full textThe first step of a risk assessment analysis is the evaluation of flood-prone areas. Nowadays, using Geographic Information System (GIS) technology for risk assessment analysis is very common. However, it is not widely used for defining inundated areas. LiDAR data, such as digital elevation models (DEM), makes GIS numerical models attractive methods for obtaining a flooded area automatically. A first approach (Federici & Sguerso, 2007; Marzocchi, 2009) uses a GIS module in order to simulate perifluvial flood maps, having as prerequisites (i) the conformation of the river floodplain by a high-resolution DEM and (ii) a water surface profile
along the river axis calculated for a given water discharge through a generic one-dimensional (1D) hydraulic model (HEC-RAS, Basement, MIKE 11, etc.). On the other hand, a second approach uses a GIS-embedded two-dimensional (2D) model in order to simulate flooded areas due to a dam break (Cannata&Marzocchi, Nat Hazards 61(3):1143–1159, 2012).
This module solves the conservative form of the 2D shallow water equations (SWE) using a finite volume method (FVM).
We present a comparison between the two models mentioned above, and we analyse the possibility of integrating these two approaches
La riabilitazione termale nel 150° Anniversario dell'Unità d'Italia. Un testimonial d'eccezione: Giuseppe Garibaldi.
No full textNell’anno in cui si celebra il 150° Anniversario dell’Unità d’Italia, il riemergere di alcune lettere di Giuseppe Garibaldi - che fanno riferimento ad un periodo di cure termali effettuato presso le Terme della Ficoncella e di Traiano (vicino Civitavecchia, Roma) - ci ha dato lo spunto per questo lavoro che intende considerare i numerosi trattamenti effettuati presso diverse stazioni termali italiane dall’Eroe dei Due Mondi per una patologia reumatica (probabilmente una poliartrite reumatoide) e per gli esiti di varie ferite di guerra, in particolare la ben nota ferita da arma da fuoco subita a livello dell’arto inferiore destro nel corso della battaglia d’Aspromonte, nel 1862
Models for the Design of Bioinspired Robot Eyes
No full textActive vision has the goal of improving visual perception; therefore, the investigation of ocular motion strategies must play an important role in the design of humanoid robot eyes. Listing's law is a basic principle, which characterizes various ocular movements in humans, including saccades and smooth pursuit, and its neural or mechanical origin has been debated for a long time. Recent anatomical advances suggest that motions compatible with Listing's law could be mainly caused by the mechanical structure of the eye plant. In this paper, we present a bioinspired model of the eye plant, and we formally prove that according to the model, the implementation of Listing's law can be actually explained on the base of the geometry of the eye and of its actuation system. The proposed model is characterized by a limited number of geometric parameters, which can be easily used to set the guidelines for the design of humanoid, and possibly tendon-driven, robot eyes. Simulative and experimental tests performed on a robot prototype are eventually presented to perform a quantitative evaluation of the performance of the model, also in comparison with physiological data measured in humans and primates and reported in the literature
