Complex sports infrastructure and urban resilience: technologies and paradigms
Get PDFThe theme of resilience applied to complex sports infrastructure is as pressing a topic today as it is little analysed in an organic, systematic manner. The social, economic and environmental repercussions of these examples of architecture are, at the urban as much as at the regional scale, equally strategic, especially evaluated in relation to the impact that the practice of sport has on contemporary society, with clear ramifications for the health sector. An overview coming from studies and researches on the current European and Italian sports infrastructure scene makes it possible to pinpoint some interesting, innovative trends which evidence, in this sector as in others, ever increasing attention the themes of eco-systemic, urban and social resilience as applied to sports infrastructure
Combination of alginate based edible coating-betel essential oil in extending the shelf life of rose apple cv. Dalhari (Syzygium samarangense)
Get PDFRose apple cv. Dalhari is a local fruit grown in Berbah District, Special Region of Yogyakarta. This fruit perishable easily loses its water content and is attacked by microbes. This research aimed to determine the best combination between alginate and betel essential oil to inhibit the growth of microbes and maintain quality of rose apple cv. Dalhari. Alginate and betel essential oil treatments were used at three concentration levels, alone and in combinations, respectively of 2%, 2.5%, 3% and 0%, 0.1%, 0.2%. The results showed that combination treatment of 2.5% alginate and 0.1% betel essential oil was the most effective to maintain the fruit quality. The sole addition of betel essential oil was not able to inhibit microbial growth. Furthermore, combination of alginate based edible coating and betel essential oil was able to maintain the quality of rose apple cv. Dalhari up to nine days
In vitro activity of some essential oils against Penicillium digitatum
Get PDFNatural plant essential oils (EOs) can be used instead of synthetic fungicides because of human health concerns and environmental protection. In this study, the in vitro activity of some plants EOs against Penicillium digitatum, the cause of citrus green mold was evaluated during 8 days of incubation at 25°C. The EOs extracted from sweet orange (Citrus sinensis), lemon (Citrus limon), lime (Citrus aurantifolia), and sour orange (Citrus aurantium) fruit peel (500, 1000 and 2000 µl l-1 concentrations), cinnamon (Cinnamomum cassia) bark and summer savory (Satureja hortensis) aerial parts (400, 500 and 600 µl l-1 concentrations) were used on Penicillium digitatum mycelium. None of the EOs extracted from tested citrus in this study could inhibit mycelial growth completely even at concentration of 2000 µl l-1. The best results were obtained with cinnamon and summer savory EOs at concentration of 500 and 600 µl l-1. So, based on the results, cinnamon and summer savory EOs can be ideal candidates to replace the synthetic fungicides to control postharvest green mold of citrus fruit. GC-MS analysis showed that the most abundant of all constituents in EO extracts were carvacrol and γ-terpinene in summer savory and (E)-cinnamaldehyde in cinnamon
Biochemical and physiological evaluations of common bermudagrass [Cynodon dactylon (L.) Pers.] Iranian accessions under cold stress
Get PDFIn this study, one foreign cultivar and forty-nine common bermudagrassaccessions were collected from 18 provinces of Iran. Turfgrasses weregrown at four temperature regimes (24/17, 7.5/0, -7.5/-12 and 15/-15°Cday/night cycles) in a factorial experiment based on the completely randomized design with three replications. Physiological traits were evaluated to categorize all accessions as either cold sensitive or tolerant using Hierarchical Clustering with Ward’s method in SPSS software. Our results revealed that cold-tolerant common bermudagrass accessions showed higher proline, protein, antioxidant enzymes, color, visual quality and chlorophyll content and cold-sensitive accessions showed more severe cell membrane damage (EL) under cold stress conditions. Fall in temperature from 24°C severely decreased chlorophyll content, visual quality and color in all accessions. The highest antioxidant enzymes activity, chlorophyll content, color and visual quality at -7.5°C were observed in Taft, foreign cultivar, Naein, Malayear, Aligoudarz, Safashahr and Gorgan accessions. The increase in POD, SOD, CAT and APX activityobserved in this study led to protection against oxidative damage caused due to high ROS levels. The most cold-tolerant accessions at -15°C were Taft, Naein and Malayear. Great variations in freezing tolerance were observed between Iranian accessions of common bermudagrass. Further molecular studies are needed to clarify better these findings
Álvaro Siza Vieira - Usiamo allora gli ormeggi al contrario
No full textCecil Balmond parla della grande vela del Padiglione del Portogallo all’Expo ’98 come di una «metaphor for the very act of structure». Affacciate sulle acque dell’estuario del Tago, struttura, spazio e poesia sono magistralmente unite dalla mano di Álvaro Siza Vieira
Spazio tecnico vs spazio architettonico. Osservazioni sull’opera strutturale di Francesco di Giorgio Martini, dai bottini senesi alle fabbriche del Ducato del Montefeltro
No full textLa sostanza del modo di comporre lo spazio architettonico in Francesco di Giorgio Martini deriva in parte dall’esercizio che l’architetto compie per la regimazione delle acque sotterranee attraverso la rete di bottini che progetta a Siena nella seconda metà del XV secolo.È possibile rilevare un’analogia tra l’energia espressiva degli spazi tecnici ipogei e quella degli spazi architettonici delle fabbriche del Ducato di Federico da Montefeltro.
Art and Entanglement in Strange Tools
Get PDFWhat is art? Why does it matter? What does it tell us about ourselves? In this essay, I introduce and in some cases extend the basic account of these matters offered in Strange Tools (New York, Hill and Wang: 2016)
L’informalità del cambiamento urbano. Pratiche e progettualità dell’abitare nel quartiere San Berillo di Catania
Get PDFThis ethnographic research focuses on the informal activities that take place in the streets of the San Berillo neighbourhood in the historical centre of the city of Catania, highlighting the stories and meanings that are linked to these uses as a production of transformation and planning. Urban regeneration is an important resource to improve the urban quality, but this process can be produce marginalization and displacement process in the city context. Rethinking the city by expanding the elements of reference, it means recognizing in the urban practices, in the meanings from the bottom and in the symbolic dimension, interpretive categories endowed with planning. Urban practices play a decisive role in the construction of the city. Although they are often more easily associated with abusivism, they constitute the fundamental and prevailing modalities of urban development. The city is not given only by a constructive process of physical space but is the result of adaptation and appropriation of spaces to redefine their uses
Lungo il cammino delle merci. Un’indagine sulle condizioni di lavoro nel settore della logistica
Get PDFThe logistic sector in Italy has been subject to a wave of strikes and trade union actions in recent years, particularly in the Pianura Padana area. Although, the protests have been documented, the analysis of working conditions are rare. Not enough consideration has been given, furthermore, to the concept of “labour exploitation” in this specific sector. In this paper, we will present an empirical research carried out in the area of Florence, through in–depth interviews with three kinds of workers: truckers, couriers and warehouse workers. The research analyses the working conditions of the interviewees and demonstrates how a model of labour exploitation has emerged in this sector, transversal to the three compartments analyse
