Multiplet coupling and band structure in L2,3-edge XAS through multi-channel multiple scattering theory.
2009
International audience; Using the recently developed multi-channel multiple scattering (MCMS) method we have calculated the x-ray absorption spectra (XAS) at the L2,3-edge of transition metal compounds. The MCMS method is an ab initio scheme which combines an accurate description of the band structure of the material with a correlated many-electron wave function on the absorber atom. Thereby configuration interaction in the XAS final state, in particular multiplet effects, can be taken into account. In the present implementation, we use an electron-hole wave function and treat the interaction with all other electrons on a mean-field level. The calculated spectra agree well with experiment f…
Mapping the political toponymy of educational namescapes: A quantitative analysis of Romanian school names
2019
Abstract This study sets out to map the political toponymy of Romanian schooling network. Starting from the theoretical premise that national memory is toponymically inscribed, inter alia, on a series of public organizations that form an institutional namescape, the paper reads the Romanian historical memory through the looking glass of school names. Exhaustive data was collected for the Romanian secondary schools bearing a nominal identity (N = 2850). Data were analyzed in terms of the ethnic and gender distribution, the social (occupational), spatial, and historical structures of the Romanian educational namescape. Our findings reveal that the political toponymy of the Romanian schooling …
Anverso y reverso de la nación: el discurso de la antiespañolada durante los primeros años 40
2015
During the immediate postwar years, different voices from the new francoist regime produced a discourse relatively spontaneous but, at the same time, recognizable enough addressed to denounce what they considered as an unacceptable deformation of the Spanishness. Basically, and in spite of the ideological differences amongst its producers, the critic raised from a common and painful nationalism which pointed at the foreign look —specially, the French romantic look— as creator and supporter of what they called España de pandereta. This look supposed a distortion and mystification of Spain as a picturesque nation that resulted in the españolada. The aim of this article is to explore this disc…
Mans mnemòniques en l’Ars demonstrativa de Ramon Llull
2014
Aquest article recupera el concepte d’art de la memòria aplicat a les obres de Ramon Llull a partir de la presentació i el comentari de figures de mans amb finalitats mnemotècniques, especulatives i predicadores, que es troben en els manuscrits lul·lians de l’Ars demonstrativa –escrita el 1283– datats del segle xiii i el xvi. En els manuscrits de Venècia (Bibl. Marciana, Lat. VI. 200), de Bèrgam (MA 365) i de San Candido (B. della Collegiata, VIII C.8), la mà està vinculada a la figura S de l’Ars demonstrativa. En el ms &.IV.6 de l’Escorial, en canvi, la mà representa la figura A. El precedent més rellevant d’aquesta iconografia manual és la mà guidoniana, en l’àmbit musical, juntament amb …
Stress response in Drosophila subobscura. II. Puff activity during anoxia and recovery from anoxia.
1987
When individuals of Drosophila subobscura at 0 hr prepupa are submitted to anoxia (4 hr and 24 hr, respectively), their puffing pattern is very similar to that shown by individuals at the moment of development in which treatment began. The same expression of genes (the same puffing pattern and the same protein pattern) is induced in this species by recovery from anoxia as well as by heat shock treatment at 31 degrees C.
High Temperatures Result in Smaller Nurseries which Lower Reproduction of Pollinators and Parasites in a Brood Site Pollination Mutualism
2014
In a nursery pollination mutualism, we asked whether environmental factors affected reproduction of mutualistic pollinators, non-mutualistic parasites and seed production via seasonal changes in plant traits such as inflorescence size and within-tree reproductive phenology. We examined seasonal variation in reproduction in Ficus racemosa community members that utilise enclosed inflorescences called syconia as nurseries. Temperature, relative humidity and rainfall defined four seasons: winter; hot days, cold nights; summer and wet seasons. Syconium volumes were highest in winter and lowest in summer, and affected syconium contents positively across all seasons. Greater transpiration from the…

Review of the volume that is configured as an essay on the declamatory phenomenon as a whole, but above all as a reading entirely internal to the first corpus of declamatory texts by Seneca il Vecchio that has come down to us
Prácticas de alto rendimiento : un enfoque configuracional aplicado al caso español
2008
Roberto.Luna@uv.es Joaquin.Camps@uv.es El principal objetivo de esta investigación es analizar diferentes configuraciones de prácticas de recursos humanos (RH) que se dan en una muestra de 183 empresas españolas. A continuación se relacionan estas configuraciones con las estrategias competitivas de las empresas con el fin de validar la estructura configuracional obtenida. Los resultados muestran tres tipos de configuraciones. La primera, empresas con prácticas de alto rendimiento (PAR) (37,5%), se caracteriza por un intenso y generalizado uso de dichas prácticas. La segunda, empresas desarrollando PAR (46,4%), se caracteriza por el uso de una amplia gama de PAR, pero con una limitada aplica…
Resolution of β-aminophosphines with chiral cyclopalladated complexes
2005
Abstract Resolution of the racemic chiral β-aminophosphines Ph 2 PCH 2 CH(Ph)NH(Ar) ( L 1 for Ar = C 6 H 5 and L 2 for Ar = 2,6-C 6 H 3 i Pr 2 ) has been investigated by use of different cyclopalladated complexes as chiral agents. The resulting complexes afford diastereomeric adducts in a 1:1 ratio. After successive crystallizations from ethanol, a d.e. of 98% was achieved for one aminophosphine palladium complex, while no significant d.e. was obtained after crystallizations from chlorinated solvents. The X-ray structure analysis has pointed out intermolecular hydrogen interactions N–H⋯Cl between the P,N ligand and the chloride ion, which are responsible for the formation and stabilization …
Preparation and structure of the 17-electron (η5-C5R5)Mo(OH)2(dppe) (R=Me, Et) organometallic compounds containing two gem-terminal hydroxide ligands
2000
International audience; Oxidation of (η5-C5R5)MoH3(dppe) (R=Me, Et) by Cp2Fe+ in wet THF leads to the formation of the corresponding (η5-C5R5)Mo(OH)2(dppe). These compounds show a low-potential reversible oxidation wave. The structure of the C5Et5 complex has been confirmed by X-ray diffraction methods: triclinic; space group ; a=11.030(1); b=12.533(1); c=16.241 (1) Å; α=68.585(7); β=75.197(5); γ=83.991(7)°; V=2020.6(3) Å3; Z=2; Dcalc=1.324 g cm−3, μ(Mo–Kα)=0.441 mm−1; R1=0.0325; wR2=0.0875 for 415 parameters and 6823 independent reflections [Rint=0.0177] with I=2σ(I). The molecule shows a four-legged piano-stool geometry with two terminal OH ligands in a relative trans configuration. The c…
