Tre Sicilie: nascita, distruzione e ri-ciclo dei paesaggi siciliani
2015
L’evoluzione delle politiche sul paesaggio in Sicilia vive una sorta di tripartizione sia storica che geografica: paesaggi tutelati e iper-protetti, paesaggi in trasformazione e paesaggi in recupero si susseguono evolutivamente nella storia dell’Isola, ma si giustappongono anche fisicamente nella contemporaneità. Questa realtà è oggetto di questo contributo che indaga evoluzione ed esiti di creazione, trasformazione e riciclo di paesaggi in alcuni territori esemplari della Sicilia, con l’obiettivo di analizzare, selezionare e proporre buone (o cattive) pratiche nell’ambito della ri-generazione dei paesaggi. Il contributo in forma di cronistoria fortemente selettiva di alcuni fenomeni che ha…
FROM SFM TO 3D PRINT: AUTOMATED WORKFLOW ADDRESSED TO PRACTITIONER AIMED AT THE CONSERVATION AND RESTAURATION
2017
Abstract. In In the last years there has been an increasing use of digital techniques for conservation and restoration purposes. Among these, a very dominant rule is played by the use of digital photogrammetry packages (Agisoft Photoscan, 3D Zephir) which allow to obtain in few steps 3D textured models of real objects. Combined with digital documentation technologies digital fabrication technologies can be employed in a variety of ways to assist in heritage documentation, conservation and dissemination. This paper will give to practitioners an overview on the state of the art available technologies and a feasible workflow for optimizing point cloud and polygon mesh datasets for the purpose …
TOWARDS AN ADVANCED CONSERVATION STRATEGY: A STRUCTURED DATABASE for SHARING 3D DOCUMENTATION between EXPERT USERS
2019
Abstract. Nowadays, the researchers in Cultural Heritage fields investigate more and more about advanced conservation strategies that comprehend the possibility to share and use 3D models and structured information related to them. One of the modern method adopted to achieve this goal is to use structured web-platform. These are online systems that can handle data, created to contain and support precise information. They simultaneously respond to the need for a common ground for different expert users and of a unique tool where to store several kinds of data, coming from heterogeneous sources. The article aims to show how it is possible to build a valid tool for the conservation and monitor…
COMPUTER AIDED RESTORATION TOOLS TO ASSIST THE CONSERVATION OF AN ANCIENT SCULPTURE. THE COLOSSAL STATUE OF ZEUS ENTHRONED
2017
Abstract. The research focuses on the contribution of the integrated application of Computer Aided Restoration digital procedures as a means to guide the integration measure of an artifact, innovating and implementing the traditional investigation methods. The aim of the study was to provide effective geometrical-formal investigation tools in the frame of the conservation work of Zeus enthroned from Soluntum, conserved in the Archaeological Museum “A. Salinas” of Palermo. The paper describes the workflow of the 3D acquisition and graphical modeling with non-invasive digitalization and high information density techniques to assist the conservation of the legs of the throne, especially the in…
ARAB-NORMAN HERITAGE: STATE OF KNOWLEDGE AND NEW ACTIONS AND INNOVATIVE PROPOSAL
2017
Abstract. This paper wants to offers a perlustrative recognition on the 'state of the studies', concerning to the Arab-Norman architecture of Palermo, admissed by Unesco in 2015 and explain a research in progress which, starting from re-cognition of the peculiarities of the restoration work carried out on it, consisting of the identification of authentic material-constructive values and / or reconstruction, it orients itself to develop a concrete proposal of filing for a more conscious knowledge. She, moreover, wants contribute to real enhancement through the use of targeted communication strategies that use innovative means capable, on one hand, to attracting the greatest possible number o…
Anthropology of Conservation in Spain. Review and perspectives
2016
En este artículo presentamos un balance de la Antropología de la Conservación en el Estado español. Durante las últimas décadas, la protección de los espacios naturales ha aumentado de una manera exponencial en todo el mundo. A la vez que se extendía esta patrimonialización de la naturaleza, los trabajos etnográficos sobre las áreas protegidas han ido ganando terreno dentro de la disciplina y, en particular, en el campo de la Antropología Ambiental. La mencionada bibliografía ha puesto de relieve los múltiples aspectos derivados de las nuevas políticas territoriales de regulación, apropiación y mercantilización de la ‘naturaleza’. En este trabajo realizamos una revisión exhaustiva de la pro…
A Financial Perspective on Value Creation
2018
The recent financial crisis, together with the economic bubbles and cycles of explosions have all proved us that creating, evaluating and maintaining value represent not only a competitive advantage, but also a requirement in uncertain situations. And when also the interests are not intercorrelated within the groups, the only way to effectively employ the available resources and to help the economy is by seeking to achieve long lasting value development. The principles used in establishing the value, followed by measurement techniques have stood the test of time. In a world where short-termism still remains a topic open to debates, it is mandatory to be able not to think of creating value f…
Impact of Farmland Abandonment on Water Resources and Soil Conservation in Citrus Plantations in Eastern Spain
2019
Due to the reduction in the prices of oranges on the market and social changes such as the ageing of the population, traditional orange plantation abandonment in the Mediterranean is taking place. Previous research on land abandonment impact on soil and water resources has focused on rainfed agriculture abandonment, but there is no research on irrigated land abandonment. In the Valencia Region&mdash
Method for Reproducible Shipboard Segmented Flow Analysis Ammonium Measurement Using an In-House Reference Material for Quality Control
2021
Ammonium is a fundamental nutrient for phytoplankton growth in seawater and is a key component of the microbial loop. Ammonium measured in parallel with other nutrients is crucial in understanding the small temporal scale changes in oceanographic ecology. Despite the importance of measuring ammonium at sea, owing to its lability, there is no consensus on the best method. The lack of availability of certified reference materials for ammonium in seawater also makes it difficult to assess the accuracy and reproducibility of ammonium measurements. In this study we present a modified segmented flow analysis method using ortho-phthaldialdehyde (OPA) with fluorescence detection to measure ammonium…
Retention forestry and biodiversity conservation: a parallel with agroforestry
2013
In forested landscapes two general management systems – retention forestry and agroforestry – have been proposed as potentially efficient components of landscape approaches to ease the conflict between biodiversity objectives and human needs. In two recent reviews, Gustafsson et al. (2012) and Lindenmayer et al. (2012) provide a global overview of current knowledge about the practice and ecological roles of retention forestry. A few years ago, Bhagwat et al. (2008) produced a similar review addressing the role of agroforestry in biodiversity conservation. Here we draw a parallel between research on the ecological effects of retention forestry and agroforestry. We argue that conservation sci…
