Confronto tra diverse localizzazioni di un impianto eolico contemperando produttività ed impatto visivo

This paper proposes a series of variations in designing the location of a wind farm on Monti della Tolfa. These project solutions aim at mitigating the visual impact caused by the wind aerogenerators. Besides the usual location of the wind aerogenerators on the skyline, these alternatives within the project design relate to the placement of wind turbines in the middle and at the bottom of the hillside. Other possible mitigation forms relate to the dimensions and the colour of the wind towers. This study proposes both a non-monetary and monetary analysis of the visual impact related to each project proposal. The final aim of the paper is to analyze economic and financial costs-benefits for each alternative to find out the economic optimal solution.

Smartphone and GPS technology for freeroaming dog population surveillance -a methodological study (Studio metodologico sull’applicazione di smartphone e tecnologia GPS alla sorveglianza delle popolazioni di cani vaganti)

Free-roaming dogs (FRD) represent a potential threat to the quality of life in cities from an ecological, social and public health point of view. One of the most urgent concerns is the role of uncontrolled dogs as reservoirs of infectious diseases transmittable to humans and, above all, rabies. An estimate of the FRD population size and characteristics in a given area is the first step for any relevant intervention programme. Direct count methods are still prominent because of their non-invasive approach, information technologies can support such methods facilitating data collection and allowing for a more efficient data handling. This paper presents a new framework for data collection using a topological algorithm implemented as ArcScript in ESRI® ArcGIS software, which allows for a random selection of the sampling areas. It also supplies a mobile phone application for Android® operating system devices which integrates Global Positioning System (GPS) and Google Maps™. The potential of such a framework was tested in 2 Italian regions. Coupling technological and innovative solutions associated with common counting methods facilitate data collection and transcription. It also paves the way to future applications, which could support dog population management systems.

Christian Gottlob Neefe and the Early Reception of Le nozze di Figaro and Don Giovanni

Cohousing di pianura. Ripensare l’abitare in chiave solidale e a zero consumo di suolo

Le riflessioni che seguono intendono offrire un contributo al dibattito sulle nuove forme di abitare intese principalmente come attitudini relazionali che, nel loro prendere forma, producono spazi dando voce quella vocazione comunitaria sempre più diffusa nella nostra società contemporanea. L’occasione di seguire da vicino il processo di trasformazione di un Gruppo di Acquisto Solidale (Gas), costituito per iniziativa di alcuni cittadini ferraresi, in un gruppo di aspiranti cohousers, seguendone le fasi di apprendimento collettivo, di dialogo con le istituzioni locali e con i diversi attori che progressivamente entrano in gioco, si inserisce in una più vasta ricerca, da tempo portata avanti da chi scrive, sulla natura delle politiche pubbliche per la città e per il territorio, con particolare riguardo a contesti relativamente marginali di cui la regione del Delta del Po può essere considerata una concreta espressione.

Geografia associativa e imperialismo svizzero. Il caso di Ginevra (1858-1914)

ASSOCIATIVE GEOGRAPHY AND SWISS IMPERIALISM. THE EXAMPLE OF GENEVA (1858-1914) − This article is about geographical society of Geneva and its involvement in the 19th century colonial imperialism. Through this society, Swiss bourgeoisie takes part in the exploration and colonization of the world. Is this participation a sign of Swiss imperialism? This issue will be at the heart of this study.

Skin permeation and metabolism of di(2-ethylhexyl) phthalate (DEHP).

Phthalates are suspected to be endocrine disruptors. Di(2-ethylhexyl) phthalate (DEHP) is assumed to have low dermal absorption; however, previous in vitro skin permeation studies have shown large permeation differences. Our aims were to determine DEHP permeation parameters and assess extent of skin DEHP metabolism among workers highly exposed to these lipophilic, low volatile substances. Surgically removed skin from patients undergoing abdominoplasty was immediately dermatomed (800 μm) and mounted on flow-through diffusion cells (1.77 cm(2)) operating at 32°C with cell culture media (aqueous solution) as the reservoir liquid. The cells were dosed either with neat DEHP or emulsified in aqueous solution (166 μg/ml). Samples were analysed by HPLC-MS/MS. DEHP permeated human viable skin only as the metabolite MEHP (100%) after 8h of exposure. Human skin was able to further oxidize MEHP to 5-oxo-MEHP. Neat DEHP applied to the skin hardly permeated skin while the aqueous solution readily permeated skin measured in both cases as concentration of MEHP in the receptor liquid. DEHP pass through human skin, detected as MEHP only when emulsified in aqueous solution, and to a far lesser degree when applied neat to the skin. Using results from older in vitro skin permeation studies with non-viable skin may underestimate skin exposures. Our results are in overall agreement with newer phthalate skin permeation studies.
