Green infrastructures for the energetic and environmental sustainability of cities

2019

The inexorable extension of urbanization is consuming huge amounts of soil drastically reducing natural vegetation, replacing it with buildings and low albedo surfaces. The changes due to the different thermal properties of surface materials and the lack of evapotranspiration in urban areas lead to a phenomenon known as "urban heat island effect". By reintroducing the vegetation back into the urban landscape, a partnership between nature and cities should be strengthened to create a new sustainable urban environment. Since the outer surfaces of building offer a great amount of space for vegetation, planting on roofs and walls has become one of the most innovative way to provide several envi…

Disappearance of malachite green residues in fry of rainbow trout (Oncorhynchus mykiss) after treatment of eggs at the hatching stage

2009

Abstract The disappearance of malachite green (MG) residues was determined in fry of rainbow trout (Oncorhynchus mykiss) after six repeated treatments of the eggs at the hatching stage with MG oxalate at exposure levels of 1, 3 and 6 mg l− 1 for 30 min. Fry samples were taken from newly hatched fry (0 days post-hatch, d.p.h.) and at regular time intervals at 16, 31, 43, 57 and 96 d.p.h. The residues of MG and its major metabolite, leucomalachite green (LMG), were found to accumulate in the fry after MG treatments of eggs, with the highest residue levels being determined in the newly hatched fry. After exposures of 3 mg l− 1 MG, mean concentrations of 1170 ± 106 µg kg− 1 and 276 ± 38.6 µg kg…

Una ipotesi di green design per la “valori-naturazione” di Caltabellotta

2020

Questo studio individua nella “valori-naturazione” del centro di Caltabellotta un campo privilegiato di sperimentazione architettonica e tecnologica. La ricerca approfondisce l’uso dell’involucro verde come sistema di possibile caratterizzazione dell’immagine urbana volto anche a riequilibrare le discontinuità causate da fenomeni di degrado edilizio. Nei vuoti urbani del borgo vengono “innestate” nuove centralità spaziali che faranno da connettori di sviluppo ecologico affinché Caltabellotta possa candidarsi a green city della Provincia di Agrigento, esplorando scenari ancora poco praticati in questo contesto. In tale ottica si studiano le specificità del tetto giardino e del giardino verti…

Palermo Blue/Green Gateway. Nove porte per la knowledge city

2015

Il saggio esplora le trasformazioni della linea di costa dell'area metropolitana di Palermo e traccia linee ed indirizzi di trasformazione legate alla rigenerazione di nove porti intesi come nuove porte di accesso alla città stessa. Il saggio presenta l'ipotesi di trasformazione e rigenerazione urbana ed architettonica che l'autore ha elaborato in occasione della candidatura di Palermo a Capitale Europea della Cultura per il 2019, in qualità di membro della cabina di regia e del coordinamento scientifico della candidatura. Lo scritto porta avanti una ipotesi teorica e di ricerca fondata sulla postproduzione urbana e architettonica e sulla knowledge city come tema trainante per la rigenerazi…

Comparative study onSalmonellaisolation from sewage-contaminated natural waters

1984

Alcaide, E., Martinez, J.P. & Garay, E. 1984. Comparative study on Salmonella isolation from sewage contaminated natural waters. Journal of Applied Bacteriology56, 365–371. A comparative study of five factors influencing the isolation of salmonellas from sewage-contaminated natural waters was carried out. The effect of pre-enrichment in buffered peptone water was compared with single-step enrichment in NR10 broth incubated at 43dC. A modification of NR10 has been compared with the original composition. Bismuth sulphite agar (BSA), Hektoen enteric agar (HE) and brilliant green agar (BGA) have been used as plating media. Other factors considered have been temperature of the water and sampling…

Carbohydrate and nutritional responses to stem girdling and drought stress with respect to understanding symptoms of Huanglongbing (HLB) in Citrus

2013

The most important worldwide problem in citrus production is the bacterial disease Huanglongbing (HLB; citrus greening) caused by phloem-limited bacterium Candidatus Liberibacter asiaticus. The earliest visible symptoms of HLB on leaves are vein yellowing and an asymmetrical chlorosis referred to as “blotchy mottle”, thought to be the result of starch accumulation. We tested the hypothesis that such visible symptoms are not unique to HLB by stem girdling 2-yr-old seedlings of two citrus rootstocks with and without drought stress in the greenhouse. After 31 d, girdling had little effect on shoot growth but girdling increased the relative growth rate of shoots in drought stressed trees. Starc…
