Motor action execution in reaction-time movements : Magnetoencephalographic study

2019

OBJECTIVE: Reaction-time movements are internally planned in the brain. Presumably, proactive control in reaction-time movements appears as an inhibitory phase preceding movement execution. We identified the brain activity of reaction-time movements in close proximity to movement onset and compared it with similar self-paced voluntary movements without external command. DESIGN: We recorded 18 healthy participants performing reaction-time and self-paced fast index finger abductions with 306-sensor magnetoencephalography and electromyography. Reaction-time movements were performed as responses to cutaneous electrical stimulation delivered on the hand radial nerve area. Motor field and movemen…

Anatomical and electrophysiological study of the vomeronasal circuits: Amygdaloid response to odours and pheromones

2017

Rodents detect information concerning the world around them mainly through two chemosensory systems: the olfactory and the vomeronasal systems. In order to develop an appropriate behavioural response to their environment, these systems exhibit both functional and physiological convergence. Further understanding of the organization and function of the olfactory systems would allow us to comprehend how their information is integrated in the brain. In a first approach we performed a thorough analysis of the connections of key structures involved in the processing of vomeronasal information: the medial (Me) and the posteromedial cortical (PMCo) amygdaloid nucleus. Then, we enquire the populatio…

Phenomenological description of the vortex density in rotating BEC superfluids

2008

The close analogy of a purely magnetic excitation scheme, used in the experiments on Bose-Einstein condensate by Hodby et al., and the rotating bucket experiments with liquid helium 4 has suggested us to apply a phenomenological equation for the vortex line density, previously proposed for rotating superfluid helium 4, to describe the vortex density in a rotating Bose-Einstein condensate as a function of the angular speed. In both systems, the phenomenological equation provides a reasonable description of the observed data.

Examining Consumers’ Usage Intention of Contactless Payment Systems

2019

Purpose The purpose of this paper is to develop and test a conceptual model that combines the modified Unified Theory of Acceptance and Use of Technology (UTAUT2) with a consumer brand engagement (CBE) model to predict consumers’ usage intentions toward contactless payment systems in a developed country. Design/methodology/approach The authors cooperated with a contactless payment service provider in Finland and reached out to 22,000 customers, resulting in 1,165 usable responses. The collected data were analyzed using structural equation modeling. Findings The study shows that the UTAUT2 and the CBE model together explain approximately 70 percent of the variance in usage intention. Of the…

Väritutkimus rakennushistorian tietolähteenä

2011

Kulttuurihistoriallisten rakennusten säilymisen turvaamiseksi tarvitaan usein käyttötarkoituksen muutos. Kun rakennukset muokataan uuteen käyttöön, niiden alkuperäiset ominaispiirteet ovat vaarassa kadota. Usein rakennuksen ulkokuori on pyritty säilyttämään, mutta sisustuksia on saatettu muuttaa. Interiöörien värityksiin ovat eri aikoina vaikuttaneet sekä kansainväliset virtaukset, erilaiset väriteoriat että taiteilijoiden makumieltymykset. Vanhempia pintoja saattaa löytyä uudempien maalikerrosten alta väritutkimuksen avulla. Eri ikäiset pinnat vaativat erilaisia tutkimusmenetelmiä. Historiallisten rakennusten tutkimustarve, tutkimusten laatu ja tutkitun tiedon talteen saaminen on kansainvä…

FRUIT AND LEAF SENSING FOR THE CONTINUOUS MONITORING OF TREE WATER STATUS IN HIGH-DENSITY ORCHARD SYSTEMS

The fast maritime transport for the waterfront revitalization of the airports in Western Sicily.

2011

In this paper we propose a new mobility model that uses sea transports for systematic and occasional users, tourists, etc.., which must reach the airports of Palermo and Trapani. In particular fast ferries, even with their operational limitations, can be used for quick links designed for the mobility demand that interests the airports of Western Sicily. These transport nodes are currently isolated because they are accessible essentially by means of rubber, given the supply shortages of the rail system. The aim of this study is to reassess the waterfront of a stretch of coast between the two Sicilian airports, places near the sea, that can use sea transport systems to reduce congestion on th…

La riqualificazione della viabilità costiera per la mobilità dolce: il caso di Palermo

2012

The attractiveness and the availability of services offered in urban areas nearby the port terminals are conditioned by the improvement of the connection of different urban transport systems and by the enhancement of the accessibility. But they should be based on the overall improvement of urban mobility. The structural organization of the territory is favored by the presence of links, which realize an infrastructure system to the different levels of connection and accessibility. The interventions could include the requalification of the coastal strip, including the road network component. Attention should be given to the supply quality, the rationalization of a linear model based on the co…

Ginger and Turmeric Essential Oils for Weed Control and Food Crop Protection

2019

Ginger and turmeric are two food ingredients that are in high demand due to their flavor and positive effects on health. The biological properties of these spices are closely related to the aromatic compounds they contain. The chemical compositions of their essential oils and their in vitro phytotoxic activity against weeds (Portulaca oleracea, Lolium multiflorum, Echinochloa crus-galli, Cortaderia selloana, and Nicotiana glauca) and food crops (tomato, cucumber, and rice) were studied. Forty-one compounds, accounting for a relative peak area of 87.7% and 94.6% of turmeric and ginger essential oils, respectively, were identified by Gas Chromatography&ndash

AMMORTIZZATORI SOCIALI E NUOVE PROSPETTIVE DI WELFARE

In linea con la costruzione di un Modello sociale europeo e con i principi di flexicurity e lotta all’esclusione sociale elaborati nel quadro della Strategia Europa 2020, lo studio ripercorre le tappe dell’auspicato processo di razionalizzazione/universalizzazione del sistema degli ammortizzatori sociali in Italia, al fine di conciliare le istanze di flessibilità del mercato del lavoro con un incremento della sicurezza sociale e dell’occupabilità. In particolare, si analizzano le rilevanti modifiche introdotte dalla legge n. 92 del 2012 (cd. Riforma Fornero), nonché quelle proposte, a distanza di neanche due anni, nell’ennesimo percorso di riforma prefigurato all’interno del cd. Jobs Act , …
