Mixed-Valence Defect Ferrites : a New Family of Fine Powders and Thin Films of Spinel Ferrites
1997
When highly divided spinel ferrites become reactive enough with oxygen, to allow the oxidation of the Fe 2+ ions at low temperature and of substitute cations too, when these cations are capable of different valence states. We prepared fine particles of spinel ferrites substituted by Mn, Mo, Cu, by chimie douce, especially from oxalate precursors and used them to reveal and to study the oxido-reduction phenomena occurring in these finely divided materials. It was shown that the oxidation created a new family of spinel ferrites : the mixed-valence defect ferrites, having specific characteristics and properties. The ferrites of this type can be fine powders prepared at low temperature, or grou…
Small angle neutron scattering on periodically deformed polymers
1984
Small angle neutron scattering from periodically deformed samples is a useful extension of the methods presently available for the study of molecular dynamics of polymers. In this paper we describe apparatus that has been used to produce large cyclic deformations at frequencies upto 10 Hz and the principles by which data is collected to give spectra corresponding to different states of strain of the sample. Some data on model polydimethylsiloxane networks is given as an illustration of the value of this technique.
L'arbitratge regi a la ciutat de Xátiva en el context previ a la introducció de la insaculació (1416-1427)
2017
Estudi documental que analitza com, a inicis del regnat d’Alfons el Magnànim, la sistemàtica lluita de bàndols entre el patriciat urbà a la ciutat de Xàtiva va determinar una ingerència règia cada vegada més decidida en les eleccions municipals. En aquest sentit, a partir de fonts arxivístiques reials i municipals, la recerca presenta el marc sociopolític existent en dita ciutat i quines foren les primeres petjades de l’arbitratge monàrquic desenvolupat per dit sobirà. En concret, s’exposen els procediments electorals municipals que es succeïren a Xàtiva des de 1416, el fracàs dels quals conduirà a l’atorgament –per primera vegada a la Corona d’Aragó– del privilegi d’insaculació en 1427.

La memoria bruciata. L'Archivio dell'Ospedale Grande di Palermo
2019
Il 18 aprile 1593 un incendio di probabile natura dolosa colpì l'archivio dell'Ospedale grande e nuovo di Palermo, collocato a piano terra di palazzo Sclafani. Nei decenni successivi l'archivio fu più volte riordinato, subì tuttavia ulteriori deterioramenti a causa di eventi bellici, trasferimenti, incuria nella conservazione. Per ricostruire la storia dell'Ospedale grande e nuovo di Palermo, entrato in funzione nel 1442 a partire dall'aggregazione di piccoli enti assistenziali preesistenti, abbiamo dunque a disposizione una documentazione discontinua, custodita da enti diversi in luoghi diversi. I primi capitoli dell'ospedale (1431) per esempio, furono conservati dall'istituzione presso cu…
New insights into Early Celtic consumption practices: Organic residue analyses of local and imported pottery from Vix-Mont Lassois
2019
The rich Mediterranean imports found in Early Celtic princely sites (7th-5th cent. BC) in Southwestern Germany, Switzerland and Eastern France have long been the focus of archaeological and public interest. Consumption practices, particularly in the context of feasting, played a major role in Early Celtic life and imported ceramic vessels have consequently been interpreted as an attempt by the elite to imitate Mediterranean wine feasting. Here we present the first scientific study carried out to elucidate the use of Mediterranean imports in Early Celtic Central Europe and their local ceramic counterparts through organic residue analyses of 99 vessels from Vix-Mont Lassois, a key Early Celti…
Recent warming in the Balearic Sea and Spanish Mediterranean coast. Towards an earlier and longer summer
2015
This paper analyses recent changes in the temperature of the Balearic Sea and surrounding coastal areas. Monthly temperature data from several weather stations located around the Balearic basin have been used to obtain land temperatures during the period 1960-2010, and monthly thermal satellite images from the Physical Oceanography Distributed Active Archive Center (PO.DAAC) covering the period 1985-2009 have been processed to obtain sea surface temperatures (SSTs) in the Balearic Sea. A rise in temperature has been observed since 1980 and increasingly in the last 25 years, with an average warming trend of 0.039 ºC/year on land for the period 1960-2010 and 0.026 ºC/year in SSTs for 1985-200…

Functional characterization of Tat protein from human immunodeficiency virus. Evidence that Tat links viral RNAs to nuclear matrix.
1990
The processes of transcription and posttranscription are assumed to proceed in close association with the nuclear matrix. In this study we demonstrated that Tat, the trans-activating protein from human immunodeficiency virus type 1 (HIV-1), binds both to the TAR region of the nascent HIV mRNAs and the nuclear matrix with high affinity. Both North/Western blotting experiments and nitrocellulose binding studies revealed that Tat binds with an association constant (K alpha) of approximately 1 x 10(9) M-1 to the TAR segment of HIV RNA; binding of Tat to this sequence which is present between position 32 and 82 downstream from the TATA box was also confirmed by gel retardation assays. Binding of…
Isoflurane is associated with a similar incidence of emergence agitation/delirium as sevoflurane in young children ? a randomized controlled study
2006
Summary Background: Children may be agitated or even delirious especially when recovering from general anesthesia using volatile anesthetics. Many trials have focused on the newer agents sevoflurane and desflurane but for the widely used isoflurane little is known about its potential to generate agitation. We investigated the emergence characteristics of small children after sevoflurane or isoflurane with caudal anesthesia for postoperative pain control. Methods: After institutional approval and parental consent, anesthesia was randomly performed with sevoflurane (n = 30) or isoflurane (n = 29) in children at the age of 3.8 ± 1.8 years during surgical interventions on the lower part of th…
