Early evolution of metazoan serine/threonine and tyrosine kinases: identification of selected kinases in marine sponges.
1997
The phylum Porifera (sponges) was the first to diverge from the common ancestor of the Metazoa. In this study, six cDNAs coding for protein-serine/threonine kinases (PS/TKs) are presented; they have been isolated from libraries obtained from the demosponges Geodia cydonium and Suberites domuncula and from the calcareous sponge Sycon raphanus. Sequence alignments of the catalytic domains revealed that two major families of PS/TK, the "conventional" (Ca(2+)-dependent) protein kinase C (PKC), the cPKC subfamily, as well as the "novel" (Ca(2+)-independent) PKC (nPKC), form two separate clusters. In each cluster, the sequence from S. raphanus diverges first. To approach the question about the or…

Polarisation dependent Raman study of single-crystal nickel oxide
2011
Abstract The magnetic domain structure and Raman scattering have been studied in NiO single-crystals with three different (100), (110) and (111) orientations. Twin-domain structure was observed in NiO(100) and NiO(110) single-crystals using cross-polarized optical microscopy. We found that the ratio of the two-magnon (at 1500 cm−1) to the two-phonon (2LO, at 1100 cm−1) Raman bands intensity is sensitive in a particular way to the type of the twin-domain pattern.
Demonstration of a correlation between young leaves, apex and young bunches specific to a young grapevine cutting in the first period of its developm…
2001
<p style="text-align: justify;">The development of hardwood cutting of grapevine comprise 4 succesive phases. Phase I: first period of shoot extension. Phase II: characterized by a slow growth due to a very low activity of the terminal bud. Phase III: reactivation of the growth consecutive to a resumption of the apical activity. Phase IV: when the growth becomes maximal.</p><p style="text-align: justify;">The objective of this work has been to identify the cause of the slowdown of the activity of apical bud during the phase II.</p><p style="text-align: justify;">In a first experiment, we have compared the effects of three modes of defoliation applied from the b…
Apprentissage implicite de régularités : Mise en évidence d'une différence d'apprentissage entre tâches motrices continues et discrètes
2005
This research is concerned with the implicit learning of regularities in continuous motor tasks (e.g., tracking tasks) and discrete tasks (e.g., Serial Reaction Time tasks). First, a reanalysis of Wulf and collaborator's studies, dealing with implicit motor learning, made it possible to highlight methodological problems and potential biases that provide alternative explanations for the apparent implicit learning obtained in their continuous tracking experiments. Indeed, by respecting a more rigorous methodology, it appears that it is quite difficult to obtain such learning in a continuous task. This led us to try to understand why it was easier to draw benefit from a repetition in a discret…
La Casa C dell'Insula IV di Tindari
2005
In forma sintetica, si espongono i primi risultati delle ricerche sulla Casa C di Tindari rivelando come l''abitazione pur sostanzialmente rimaneggiata in età tardo antica riveli nella sostanza il suo impianto originario di età ellenistica. Esso, in luogo della consueta attribuzione alla cultura abitativa romana, viene rapportato ad altri esempi greco-ellenistici, primi fra tutti quelli di Delo. Sono anche tratteggiati i principi compositivi di base sottesi alla progettazione dell''abitazione nella sua interezza e delle parti più rilevanti di essa, fra cui il peristilio.
La Casa dell'insula C IV di Tindari: impianto e Trasformazioni
2010
In questo lavoro, derivato da parte della tesi di Dottorato, la Casa C viene inserita nel contesto più generale dell''isolato IV, di cui fa parte, del quale viene tracciata la storia delle trasformazioni dalla fondazione dionigiana in poi, evidenziando i problemi interpretativi delle precedenti sintesi sulle trasformazioni urbanistiche della città. Dell''abitazione viene fornita una minuziosa descrizione corredata da un nuova planimetria e tre sezioni redatte in scala 1:50. Attraverso la duplice lettura dell''analisi stratigrafica della fabbrica, corredata da un''esemplificazione grafica delle tecniche murarie individuate, e della decodifica minuta delle caratteristiche geometriche del prog…
