Practical procedure for verification of compliance of digital mobile radio base stations to limitations of exposure of the general public to electrom…
2002
In the last few years, society has witnessed the installation of an ever increasing number of radio base stations as a necessity for handling new capabilities and services to the large number of users. This rapid development of wireless networks, however, has induced a marked mistrustful attitude in people, who fear possible biological effects of electromagnetic emissions from mobile communications base stations. While there are guidelines on the limitation of human exposure to electromagnetic fields (emf ), there is no harmonised standard measurement procedure to evaluate compliance with the limits on exposure in the vicinity of a base station. The measurement procedure has to be practical…
Mobile Phone Chips Reduce Increases in EEG Brain Activity Induced by Mobile Phone-Emitted Electromagnetic Fields
2018
Recent neurophysiological studies indicate that exposure to electromagnetic fields (EMFs) generated by mobile phone radiation can exert effects on brain activity. One technical solution to reduce effects of EMFs in mobile phone use is provided in mobile phone chips that are applied to mobile phones or attached to their surfaces. To date, there are no systematical studies on the effects of mobile phone chip application on brain activity and the underlying neural mechanisms. The present study investigated whether mobile phone chips that are applied to mobile phones reduce effects of EMFs emitted by mobile phone radiation on electroencephalographic (EEG) brain activity in a laboratory study. T…
Consumer Awareness and the Use of Payment Media: Evidence from Young Finnish Consumers
2008
In the market for payment media, some consumers use only one medium when paying for their point-of-sale transactions, while others use many. This pattern reflects the diffusion of new payment media, because a payment method innovation is typically first used simultaneously with the established methods. We study the use of multiple payment media by employing data on young Finnish consumers. We find that the use of multiple payment media is directly related to consumer awareness and that not controlling for the endogeneity of awareness can bias its effect downwards. These results suggest that increasing consumer awareness may have been underlying the rise of debit card use around the world. I…
Publish-subscribe smartphone sensing platform for the acute phase of a disaster: A framework for emergency management support
2014
The advanced sensors embedded in modern smartphones opens up for novel research opportunities, as for instance manifested in the field of mobile phone sensing. Most notable is perhaps research activities within human activity recognition and context-aware applications. Along a similar vein, the SmartRescue project targets monitoring of both hazard developments as well as tracking of people in a disaster, taking advantage of smartphone sensing, processing and communication capabilities. The goal is to help crisis managers and the public in early hazard detection, hazard prediction, and in the forming of risk minimizing evacuation plans when disaster strikes. In this paper we propose a novel …
Una sfida al Polo. Salgari e il mito moderno dell'automobile, on line sul sito www.emiliosalgari.it
2009
Presentazione del romanzo di avventure «Una sfida al Polo», pubblicato da Emilio Salgari nel 1909 presso l'editore Bemporad di Firenze. In particolare ci si sofferma sul ruolo e l'importanza che l'automobile - allora un mezzo da poco scoperto e utilizzato - ricopre all'interno della narrazione.
Evaluating the Performance of Real Time Videoconferencing in Ad Hoc Networks Through Emulation
2008
The validation of new video protocols and applications for mobile ad hoc networks in a real environment is an important task. In this work we present Castadiva, a test-bed architecture that allows validating software solutions for ad hoc networks using low-cost, off-the-shelf devices and open source software. We use this tool to test a videocall using the OLSR protocol in different scenarios, varying the number of hops between the caller and the receiver. The results obtained in this paper show that, for an ad hoc network with a large number of hops, the quality of videocalls suffers a significant degradation even in the absence of mobility.
Choledochocele imaged with magnetic resonance cholangiography.
2000
Choledochal cysts are rare developmental malformations of the biliary tree. Percutaneous and endoscopic ultrasound, as well as endoscopic retrograde cholangiopancreatography, are recommended diagnostic tools. Magnetic resonance cholangiography may also contribute to the workup and treatment plan of patients with choledochal cysts. We report a 25-yr-old white woman with episodic nausea and moderate epigastric dyscomfort. Magnetic resonance cholangiography showed a rather spherical, cyst-like, fluid-filled structure in continuity with the prepapillary segment of the common bile duct, thus making a choledochocele (type III choledochal cyst) likely. The patient was treated by endoscopic sphinct…
Endoscopic ultrasonography findings in autoimmune pancreatitis
2011
Endoscopic ultrasonography is an established diagnostic tool for pancreatic masses and chronic pancreatitis. In recent years there has been a growing interest in the worldwide medical community in autoimmune pancreatitis (AIP), a form of chronic pancreatitis caused by an autoimmune process. This paper reviews the current available literature about the endoscopic ultrasonographic findings of AIP and the role of this imaging technique in the management of this protean disease.
Sui territori dell'energia del trapanese, ovvero su un contro-progetto di paesaggio
2015
Il contributo propone un’analisi sulle condizioni di conflittualità derivanti da un processo di trasformazione del territorio, quale esito della mera sovrapposizione di interventi puntuali, privi di una visione strategica d’insieme, sull’ambiente e sul paesaggio. Tale condizione si verifica, sempre più diffusamente, in relazione alla localizzazione degli impianti ad energia rinnovabile, che si registra non soltanto in contesti territoriali spesso caratterizzati dalla presenza di aree di interesse naturale e paesaggistico, ma soprattutto in corrispondenza delle aree agricole. In assenza di adeguati livelli di tutela che ne salvaguardino i valori colturale e culturale, queste aree rappresenta…
Il PAES di Palermo: azioni ed interventi di una città in divenire CITTA' COME MOTORE DI SVILUPPO DEL PAESE - The Sustainable energy action plan of Pa…
2013
Il Patto dei Sindaci costituisce la cornice europea per coinvolgere attivamente le città nella strategia verso la sostenibilità energetica e ambientale. L’iniziativa, lanciata nel 2008 nell’ambito della seconda edizione della Settimana europea dell’energia sostenibile, ha portato all’adesione di oltre 1600 città tra cui 20 capitali europee e numerose città di paesi non membri dell’UE, con una mobilitazione di oltre 140 milioni di cittadini. Il Patto allo stato attuale si colloca tra i principali strumenti di sviluppo sul territorio nazionale dei principi di sostenibilità urbana, portando come valore aggiunto il merito di poter essere motore per il rilancio dell’economia e dell’immagine di m…
