Strategie ecosistemiche e infrastrutture verdi in simbiosi con il costruito
2022
Il numero 11 di AGATHÓN raccoglie saggi, studi, ricerche e progetti sul tema Vegetazione | La sua Simbiosi con il Costruito richiamando il ruolo che la Natura in generale e la Vegetazione in particolare possono svolgere nel breve periodo per affrontare l’attuale sfida del surriscaldamento globale e dei cambiamenti climatici causati da deforestazioni e incendi boschivi, urbanizzazioni selvagge, uso indiscriminato di materie prime non rinnovabili e incremento delle emissioni di anidride carbonica, tutti fattori che determinano un impatto devastante sul nostro ormai fragile ecosistema, sulla società e sull’economia. Se Simon aveva intuito già nel 1969 il potenziale di una ‘nuova ecologia’ in c…
Un approccio progettuale per la rigenerazione sostenibile
2020
This paper describes the methodology of research and analy- sis that have been adopted in order to develop the targets of the project, along with the design proposal. A literature review about urban regeneration ad its best practices and a deep study of the various features and peculiarities of the area has been conducted. Such a study guided the definition of the criteria that must be ap- plied to develop the project. The proposal of urban regeneration aims to retrain the whole di- strict by retrofitting ENPAM’s buildings and industrial sheds by the railway as well as redesigning the public spaces and the green areas. The remainder of this paper is organized as follows. The first section o…
Polyamide-Based Fibers Containing Microwave-Exfoliated Graphite Nanoplatelets
2016
Exfoliated Graphite NanoPlatelets (GNP) have been obtained from Graphite Intercalation Compounds (GIC) subjected to thermal and microwave treatments. Accurate morphological and structural characterization of obtained GNP, performed to compare the degree of exfoliation, show that microwave-treated GNP, exhibit well-exfoliated structure, without any reduction in dimensions compared with the native GIC, differently to the thermal-treated ones. Microwave-treated GNP have been introduced in polyamide (PA) through melt-mixing to obtain nanocomposite that has been subjected to elongational flow, with the aim to improve the nanofiller dispersion and induce GNP orientation along the fiber direction.…
Colisión de los derechos del artículo 18 CE con los métodos modernos de control empresarial: especial referencia a la jurisprudencia, comparación con…
2009
En las siguientes páginas se abordará el problema de la efectividad de los derechos del artículo 18 CE en el ámbito laboral. Estos derechos de carácter personalísimo ostentan la protección constitucional, formando parte del grupo de los llamados derechos fundamentales. Precisamente, su configuración como derechos fundamentales hace que requieran una atención e importancia capital. Existiendo diversos tipos de injerencias que pueden conculcar los referidos derechos, nos centraremos principalmente en la concreta violación de los mismos que resulta de la instalación de videocámaras y sistemas de microfonía ocultos, así como en la originada por el control de las aplicaciones informáticas (corre…
Nano-structured materials in new and existing buildings: to improved performance and saving of energy
2009
Improving well-being in buildings, in relation to energy conservation, represents a great challenge. In southern Italy a basic problem is that of keeping buildings cool in the summer months. This problem affects not only newly-erected buildings, but also the large number of existing buildings, some of which are of historical importance. Nano-technology represents an excellent opportunity to harness the salvage of existing buildings to the living requirements of contemporary society. The use of nano-structured materials in newly-erected buildings will lead to improved performance and a considerable saving of energy. Above all, the use of nano-structured materials in existing buildings will p…
On the impact of within-die process variation in GALS-Based NoC Performance
2012
[EN] Current integration scales allow designing chip multiprocessors (CMP), where cores are interconnected by means of a network-on-chip (NoC). Unfortunately, the small feature size of current integration scales causes some unpredictability in manufactured devices because of process variation. In NoCs, variability may affect links and routers causing them not to match the parameters established at design time. In this paper, we first analyze the way that manufacturing deviations affect the components of a NoC by applying a new comprehensive and detailed within-die variability model to 200 instances of an 8¿8 mesh NoC synthesized using 45 nm technology. Later, we show that GALS-based NoCs pr…
Glass Surfaces for Benefits of Daylight in Social Housing
2017
Internal environment and appropriate natural lighting of the building interior largely affects the health status and course of treatment of patients with psychiatric diagnoses such as depression, Alzheimer and disorder of functions. In particolar, this paper aims to show how smart glass surfaces, allowing the entry of natural lighting, can better support therapeutic process. It is important to elaborate knowledge for optimized lighting conditions in different healthy populations as well as in patients suffering from visual impairments and circadian rhythm disorders. To contribute to the development of new technologies about smart glass surfaces related to various aspects of light conditions…
Smart Materials in Architecture
2016
The project activity presides over the choice of materials and technical capacity within two dimensions of action: the previous knowledge and the tension about the future. That allowed us to identify the succession of the “technological and material” paradigms that have come and gone, featuring the project with the arrival of new materials and production processes. The advent of composite smart materials has challenged all the materials overturning the features.
Advances in Research for Biomimetic Materials
2018
Smart surfaces and materials can play a significant role in intelligent, adaptive and responsive envelopes because of these intrinsic properties. The environmental question and energy efficiency in which the construction sector is involved, is in a process that can not be interrupted and that puts researchers and designers in front of a scientific and design challenge in which it is necessary to contribute to find different ways of study and experimentation on new materials and constructive languages, ranging from the application, to the structural, design and molecular, to mention the main ones. The development of technologies is helping architects of the “biomimetic current” to recreate c…
Forest operations in coppice: Environmental assessment of two different logging methods
2016
Wood is a renewable resource and it actively contributes to enhance energy production under a sustainable perspective. However, harvesting, transport and use of wood imply several consequences and impacts on environment. There are different ways for managing forests dedicated to wood production and a sustainable approach is fundamental to preserve the resource. In this context, Life Cycle Assessment (LCA) is a useful tool for estimating the environmental impacts related to renewable resources. Traditional coppice is a common approach for forest management in several areas, including southern Europe and, specifically, Italy, Spain and the Balkans. Due to different terrain conditions, differe…
