Functional analysis of broadly tuned odorant receptors expressed in the mouse septal organ through patch-clamp recordings in an intact preparation an…
2010
The septal organ (SO) is a small island of olfactory epithelium located at the ventral base of the nasal septum. SO neurons express identified odorant receptors, but its function remains unknown. Using perforated patch clamp recordings, we investigated the response properties of SO neurons in the intact epithelium of mice to a panel of 45 odorants or mixtures. Out of 328 neurons tested, approximately 70% responded to odor stimulation. Among the responsive neurons, 72.5 % responded to multiple odorants. Responding neurons were tested with increasing concentrations of 3 odorants (octanoic acid, (+) camphor, amylacetate) and a mixture (fox urine). Dose-response curves show nanomolar threshold …
Système olfactif et neurobiologie
2006
Les connaissances neurobiologiques sur l’odorat progressent désormais rapidement depuis la découverte des récepteurs des odorants, remarquables par leur grand nombre et leur diversité. Des réponses sont maintenant apportées aux questions posées par les propriétés originales de la perception olfactive dont beaucoup sont déterminées dès le niveau de l’organe olfactif, et sont fortement déterminées par la génétique. Les connaissances génétiques sur les récepteurs dévoilent une considérable réduction du nombre de gènes olfactifs fonctionnels dans l’espèce humaine et alimentent une réflexion sur l’évolution de l’odorat. Autre avancée riche de promesses : l’application à l’olfaction des méthodes …

Vecchie e nuove minoranze: definizioni e strumenti di tutela
2018
This papers studies different issues related to minorities rights. After trying to define what should be intended as minorities in contemporary West societies and exploring if it is possible to make a difference between old and new minorities, the research focuses on the main issues that are at stake. In particular, the paper aims at discovering which are the rights involved and how such rights can be categorised, as human, cultural, individual or community rights. The research will show how new minorities are in need of having their own identities recognised and protected by our West societies. This requires the achievement of a real process of integration to be carried out through two com…
The odour of human milk: Its chemical variability and detection by newborns
2019
International audience; Human milk odour has for long elicited research interest with regard to its function in breastfeeding initiation. The present review aims to provide an overview of the behavioural effects of human milk odour in the human neonate, considering different types of response measures in a feeding or non-feeding context. Further, an overview of the current knowledge of odorant composition and factors influencing milk odour is provided by summarizing results from analytical studies using olfactometry, and addressing changes in milk odour due to storage, lactational stage, and maternal dietary intake of odorous substances. We finally highlight some issues for future research.
The life cicle of Plasmopara viticola
2000
Plasmopara viticola (Berk. & M. A. Curtis) Bed. & De Toni is an obligate biotrophic oomycetous organism which causes downy mildew of grape vine. An understanding of its life-cycle is essential in relation to the pathology and epidemiology, and for the development of better control of the disease. It overwinters as oospores within fallen leaves.
Per un museo diffuso di arte contemporanea: il quartiere Eur a Roma. Frammenti di storia e paesaggio tra preesistenze archeologiche, architettura, ar…
2015
Abstract Obiettivi. Attraverso una lettura storico-artistica di alcuni manufatti collocati nel quartiere romano dell’Eur realizzati tra gli anni trenta e la fine degli anni novanta del Novecento, si vuole tracciare un percorso didattico, culturale e turistico che valorizzi il museo diffuso presente nel quartiere. Metodologia. La metodologia storico-artistica adottata comprende l’analisi del possibile Museo Diffuso analizzato rispetto al contesto spazio-temporale di realizzazione, il rapporto con la committenza, lo studio del profilo biografico e artistico degli autori coinvolti, il confronto con altre aree disciplinari. Risultati. L’intervento mira a tradurre i contributi scientifici sull’a…

Funktionaalisia a posteriori virhearvioita Uzawan tyyppisille menetelmille kokoonpuristumattomien virtausten tapauksessa
2012
Stokesin yhtälöllä voidaan kuvata nesteiden ja kaasujen liikettä, jos liike on yksiulotteista tai hidasta. Stokesin yhtälö on yksinkertaistettu ja linearisoitu versio Navier-Stokesin yhtälöistä. Tässä tutkielmassa keskitytään kokoonpuristumattomiin ja viskoottisiin nesteisiin ja kaasuihin. Kokoonpuristumattomuus tarkoittaa sitä, että nesteen tai kaasun tiheys ei muutu ajan suhteen. Viskoottisuus taas tarkoittaa sitä, että nesteillä ja kaasuilla on sisäistä kitkaa, joka muodostuu, kun aineen osaset liikkuvat toistensa suhteen. Vaikka osittaisdifferentiaaliyhtälöiden tutkimus on edennyt viime vuosisadalla hyvinkin nopeasti, on analyyttisen ratkaisun löytäminen vaikeaa tai lähes poikkeuksetta …
