    Get PDF
    The National Trust is a charity that cares for over 300 publically accessible historic buildings and their contents across England, Wales and Northern Ireland. There have been few previous studies on preservation of plastics within National Trust collections, which form a significant part of the more modern collections of objects. This paper describes the design of an assessment system which was successfully trialled at Mr Straws House, a National Trust property in Worksop, UK. This system can now be used for future plastic surveys at other National Trust properties. In addition, the survey gave valuable information about the state of the collection, demonstrating that the plastics that are deteriorating are those that are known to be vulnerable, namely cellulose nitrate/acetate, PVC and rubber. Verifying this knowledge of the most vulnerable plastics enables us to recommend to properties across National Trust that these types should be seen as a priority for correct storage and in-depth recording

    Get PDF
    The type and quantity of lunar materials needed to support a space power satellite program was used to define the type and quality of geological information required to certify a site for exploitation. The existing geological, geochemical, and geophysical data are summarized. The difference between these data and the required data for exploitation is used to define program requirements. Most of these requirements involve linear extensions of existing capabilities, fuller utilization of existing data, or expanded use of automated systems

    Urban Regeneration and Soft Mobility: The Case Study of the Rimini Canal Port in Italy

    Get PDF
    The increasing need to reduce emissions and the environmental impact of urban areas to meet European decarbonisation goals motivates the selection of the Rimini Canal Port as a case study within the FRAMESPORT project, part of the European Interreg Italy–Croatia programme. A preliminary historical–documental and urban regulations analysis of the context allowed the identification of the main criticalities and potentials through a SWOT analysis. The central role of the stakeholders enabled the creation of a successful participatory co-design process developed through online surveys. Critical issues that emerged during the data collection phase were prioritised through a BOCR model, a powerful multi-criteria analysis tool. The project phase then focused on the resolution of the two main critical issues that emerged: the improvement of cycle/pedestrian paths, and the raising of the flooding docks in the Canal Port area. This article intends to demonstrate the strong influence of soft mobility in urban regeneration projects, and how an improvement of the quality of cycle/pedestrian paths can increase the quality of urban spaces. The new paths create a green infrastructure that contributes to a reduction in pollutant emissions through the promotion of sustainable mobility systems and an increase in green urban spaces

    Review of the radiographic modalities used during dental implant therapy - A narrative

    Get PDF
    The introduction of digital x-ray receivers which replaced conventional films was a significant radiographic development that is commonly used in daily dental practice. Dental implant therapy (DIT) is a sought after dental therapeutic intervention and dental radiography is an essential component contributing to the success of treatment. Dental radiographs taken in daily practice are generally conventional two-dimensional images and/or three-dimensional images. Ideally, the choice of radiographic technique should be determined after a thorough clinical examination and comprehensive consideration of the advantages, indications, and drawbacks. Digital three-dimensional modalities that have emerged over the last decade have been incorporated into DIT with the assumption that treatment outcomes will be improved. These modalities are constantly being reassessed and improved but there is a paucity of published information regarding the assessment of variables such as dosages and dimensional accuracy, suggesting that further research in these matters is necessary. This is crucial in order to obtain evidence-based information that may influence future radiographic practices. In this narrative, the authors present the most commonly used dental radiographic modalities currently used in DIT

    Housing values of the Olivetti villas in the Ivrea real estate market.

    The residential heritage in Ivrea, built during the most successful years of famous Italian company Olivetti, is made up of assets that can be traced back to the Modern Movement of the Twentieth Century. The site "Ivrea, industrial city of the XX Century" was included in the World Heritage List in 2018, which shows the value and originality of the Ivrea experience and recognizes its identity as a city-laboratory. The aim of this article is to analyse the potential enhancement of the Olivetti villas of Ivrea within their fragile socio-economic context and to check whether their architectural quality and the “Olivetti connotation” is recognized by the real estate market. Furthermore, the energy efficiency upgrade of the residential heritage is investigated in order to understand if and how it is able to enhance the value of the buildings and influence listing prices in Ivrea’s real estate market. The influence of some intrinsic and extrinsic characteristics on listing prices was measured by creating a sample of residential units listed on the market and by applying a multiple linear regression model, which was used for both descriptive and predictive purposes. The results showed that the Ivrea’s real estate market can be more positively affected by energy retrofitting, despite the architectural quality of the buildings, which is monetized but with a considerably lower marginal price

    3D models acquisition and image processing for virtual musealization of the spezieria di Santa Maria della Scala, Rome

    This study was carried out within the project 'Roma Hispana. Nuevas tecnologías aplicadas al estudio histórico, la musealización y la puesta en valor de Patrimonio Cultural espaùol en Roma: la spezieria di Santa Maria della Scala' (Universitat de València Spain), which is funded by the Conselleria d'Innovació, Universitats, Ciència i Societat Digital of the Generalitat Valenciana (2020-2021) and authorized by the Sovrintendenza Speciale Archeologia Belle Arti e Paesaggio (Special Superintendence of Archeology, Fine Arts and Landscape) of Rome, Italy. The spezieria di Santa Maria della Scala was the oldest apothecary in Europe managed by the order of Discalced Carmelite friars. Operating between the second half of the seventeenth century and the mid-twentieth century, over time it acquired great prestige, becoming known as the Pharmacy of the Popes. The aims of the 'Roma Hispana' project are to study, musealize and disseminate the material and immaterial cultural heritage of this historical spezieria by combining physicochemical and cultural studies, new 3D technologies, and artificial intelligence. As a case study, in this paper we report the application of a laser scanner prototype for 3D color imaging of the spezieria's sales room and use a simpler photogrammetry method to collect analogous data in the small nearby storeroom coupled to the high-power capabilities of the ENEA parallel computer facility. Digital data were collected to enable a virtual tour that provides a fully navigable, faithful, high-resolution 3D color model to render this ancient Roman apothecary accessible and usable to interested members of the public and experts in the sector (art historians, restorers, etc.). We also describe the 3D technology used to obtain threedimensional images of the cultural assets of these spaces (mostly drug containers) and its results. The ultimate aim of this study is to achieve the virtual musealization of the heritage complex

    The urban landscape pattern, process and function have three-dimensional characteristics, and the three-dimensional analysis of urban landscape elements is one of the important trends in the development of urban landscape research. However, the current research on the visualization of urban landscape in three dimensions and the application of related models still needs to strengthen. Based on the research of the ecological restoration process, this paper combines the current situation of urban landscape construction along the Yangtze River in China and deduces the development trend of urban landscape planning. Based on Building information model (BIM), this article combines Revit software to design landscape construction drawings, and summarizes the specific design process and the current unsolvable problems. As an experimental building information model (BIM) software construction drawing design attempt, this article explores the urban ecological water conservancy landscape planning and design path, and demonstrates it in combination with specific cases. Therefore, this paper conducts modeling based on three-dimensional virtual landscape, which conducts virtual landscape design and provides technical ideas for the development of this technology

    Mission analysis of Hevelius-lunar microsatellite mission

    Get PDF
    This paper describes the mission analysis and design of the 'Hevelius - Lunar Microsatellite Mission'. The main goal of the overall mission is to place a net-lander on the far side of the Moon to perform some scientific experiments. Two different satellites have been designed to achieve this objective: a microsatellite orbiter to support the net-lander and a carrier spacecraft to transport the net-lander. An L2 Halo orbit has been selected for the orbiter in order to have a constant communication link between the landers and the Earth. The invariant manifolds of the Earth-Moon system have been used to design a low cost transfer trajectory to the L2 Halo orbit. Prior to the beginning of landing operations the carrier is parked into a frozen orbit after a WSB transfer. Finally the descent and landing phases have been designed in order to accomplish the final goals. The whole mission analysis and design process has been driven by the need for a low cost and low risk mission
