More info: An effective biodiversity conservation in Protected Areas (PAs) requires that they are seen as part of larger ecosystems and that the ecological connectivity is maintained beyond PA administrative boundaries. The study of ecological processes that link PAs to their surrounding landscapes is thus of great importance to understand which actions should be implemented to promote inside-outside ecological connectivity. In this paper, we used a system of indicators and a mathematical model (PANDORA model) to describe in a quantitative way the present and the foreseen ecological state of a Regional Nature Park (Parc Naturel Régional de la Montagne de Reims) and its surrounding area. The landscape ecological quality was assessed in terms of the capability of the system to transmit its biological energy all around its territory, thus highlighting the degree of ecological connectivity in landscapes situated both inside and outside the Park. The outcomes showed how the areas situated outside the Park are characterized by a less positive evolutionary trajectory with respect to those situated inside the Park. This is mainly due to urbanization processes that are taking place precisely outside the Parks' boundary. To avoid the risk of Park's “insularization”, the need and ways of developing integrated inside-outside planning and management policies, both by the Park Authority and external authorities, is highlighted. The mathematical approach presented here could be replicated also in other PAs, to sustain and address an integrated spatial planning of PAs and their context.

The Green and Blue Infrastructure Projects in Spatial Planning as a Key Component for Adaptation to Climate Change
Author(s): Grazia Brunetta
More info: In recent decades, we have been witnessing on a planetary scale a weak or almost zero response capacity of the cities and territories to the events caused by the ongoing systemic dynamics of climate change. The significant effects of climate change are the result of the increasingly high temporal frequency of extreme natural phenomena and the greater vulnerability of soils, the result of the intense and growing dynamics of urbanization and the consequent fragmentation of natural environments. The process of fragmentation of natural environments due to anthropic causes is the primary cause of biodiversity loss, generating ecological losses and environmental and landscape challenges.

Dynamic Models for Exploring the Resilience in Territorial Scenarios
Author(s): Vanessa Assumma, Marta Bottero, Giulia Datola, Elena De Angelis, Roberto Monaco
More info: The present paper focuses on the role covered by dynamic models as support for the decision-making process in the evaluation of policies and actions for increasing the resilience of cities and territories. In recent decades, urban resilience has been recognized as a dynamic and multidimensional phenomenon that characterizes urban and metropolitan area dynamics. Therefore, it may be considered a fundamental aspect of urban and territorial planning. The employment of quantitative methods, such as dynamic models, is useful for the prediction of the dynamic behavior of territories and of their resilience. The present work discusses the system dynamics model and the Lotka–Volterra cooperative systems and shows how these models can aid technicians in resilience assessment and also decision makers in the definition of policies and actions, especially if integrated in wide evaluation frameworks for urban resilience achievements. This paper aims to provide an epistemological perspective of the application of dynamic models in resilience assessment, underlying the possible contribution to this issue through the analysis of a real case study and methodological framework. The main objective of this work is to lay the basis for future compared applications of these two models to the same case study.

Application of Essential Oils to Control the Biodeteriogenic Microorganisms in Archives and Libraries
Author(s): Francesca Bosco, Chiara Mollea, Micaela Demichela, Davide Fissore
More info: Microbial contamination control in indoor environments, such as libraries and archives, represents a challenge. Essential oils (EOs), well-known for their antimicrobial properties, have been applied in pharmaceutical and food industry from many years. In the present study, Thymus vulgaris and Origanum vulgare EO antimicrobial efficacy on paper-born microorganisms, Staphylococcus epidermidis, Rhodotorula mucilaginosa and Alternaria alternata, was investigated to protect water-damaged paper documents and to control indoor air quality for operator’s health safety. T. vulgaris EO was the most effective: Minimum Inhibitory Concentration (MIC) values obtained for S. epidermidis and R. mucilaginosa, with a broth macro-dilution method, were 7.5 microgram/mL and 5.63 microgram/mL, respectively. T. vulgaris EO (0.75% v/v), nebulized immediately after the inoculation on agar plates or paper sheets, showed a high inhibition effect against the three biodeteriogenic microorganisms, also when lyophilized on paper sheets; in this last case, the EO has a higher efficacy when applied immediately after the freeze drying. Regarding the EO effect against A. alternata, the inhibition percentage of the mycelial growth, MGI, (81.4%), observed for nonsporulated mycelium, was higher than that for the sporulated one (51.4%). Finally, T. vulgaris EO (0.75% v/v) was effectively applied on a real contaminated book cover by means of EO impregnated contact sheets. Obtained results demonstrated that tested EOs were able to delay or completely inhibit paper-born microorganism growth for both flood-independent or -dependent contamination.

Modal Identification of Structures with Interacting Diaphragms
Author(s): Rosario Ceravolo, Erica Lenticchia, Gaetano Miraglia, Valerio Olivia, Linda Scussolini
More info: "System identification proves in general to be very efficient in the extraction of modal parameters of a structure under ambient vibrations. However, great difficulties can arise in the case of structures composed of many connected bodies, whose mutual interaction may lead to a multitude of coupled modes. In the present work, a methodology to approach the identification of interconnected diaphragmatic structures, exploiting a simplified analytical model, is proposed. Specifically, a parametric analysis has been carried out on a numerical basis on the simplified model, i.e., a multiple spring–mass model. The results were then exploited to aid the identification of a significant case study, represented by the Pavilion V, designed by Riccardo Morandi as a hypogeum hall of the Turin Exhibition Center. The structure is indeed composed of three blocks separated by expansion joints, whose characteristics are unknown. As the main result, light was shed on the contribution of the stiffness of the joints to the global dynamic behavior of structures composed of interacting diaphragms, and, in particular, on the effectiveness of the joints of Pavilion V."
