Tritija termodesorbcija no plazmas kamerā izmantotiem oglekļa šķiedras kompozīt materiāliem
2015
Darbā pētīta tritija termodifūzija no kodolsintēzes iekārtas Apvienotais Eiropas tors (Joint European Torus - JET) divu darbības kampaņu periodiem (2007-2009 un 2010-2012) ar atšķirīgu pirmās sienas konstrukciju. Tritija termodifūzija veikta plazmas skartiem vienādās divertora pozīcijās esošiem ar volframu nepārklātiem un pārklātiem ķieģeļiem un 2010. gadā savāktam vakuuma kameras putekļu un plēkšņu maisījumam. Tritija maksimālais izdalīšanās ātrums no oglekļa C-sienas konstrukcijas divertora ķieģeļiem bez volframa pārklājuma (2007-2009. gada kampaņa) ir ap 730 K. 2010.-2012. gada kampaņas ar volframu pārklātajam jeb ILW-paraugam tritija izdalīšanās maksimuma temperatūra tiek sasniegta ātrā…
Rotational Raman spectroscopy of ethylene using a femtosecond time-resolved pump-probe technique.
2005
154309; Femtosecond Raman-induced polarization spectroscopy (RIPS) was conducted at low pressure (250 mb at 295 K and 400 mb at 373 K) in ethylene. The temporal signal, resulting from the beating between pure rotational coherences, was measured with a heterodyne detection. The temporal traces were converted to the frequency domain using a Fourier transformation and then analyzed thanks to the D2hTDS software (http://www.u-bourgogne.fr/LPUB/shTDS.html) dedicated to X2Y4 molecules with D2h symmetry. The effective Hamiltonian was expanded up to order 2, allowing the determination of five parameters with an rms of 0.017 cm(-1). Special care was taken in the precise modeling of intensities, taki…
High-dimensional mixed-valence copper cyanide complexes: Syntheses, structural characterizations and magnetism
2009
International audience; Reactions of CuCl 2 with different CN complexes in presence of a neutral ancillary ligand lead to two novel mixed-valence Cu complexes [Cu II (bpy)Cu I (CN) 3 ] n , 1 (bpy=2,2′-bipyridine) and {[Cu II (tn) 2 ][Cu I 4 (CN) 6 ]} n 2 (tn=1,3-diaminopropane). For compound 1, the asymmetric unit involves two Cu ions Cu1 and Cu2 (Cu I and Cu II centres, respectively) which strongly differ in their environments. The Cu1 ion presents a CuC 4 pseudo-tetrahedral geometry, while the Cu2 ion presents a CuN 5 slightly distorted square-pyramidal geometry. The extended structure of 1 is generated by three cyano ligands which differ in their coordination modes. One CN group has a μ …
QTAIM View of Metal-Metal Bonding in Di- and Trinuclear Disulfido Carbonyl Clusters
2012
The experimental and theoretical charge densities in the sulfido-bridged cluster compounds Fe2(μ-S2)(CO)6 (1), Fe3(μ3-S)2(CO)9 (2), Mn2(μ-S2)(μ-CO)(CO)6 (3), and Fe2(μ-S2)(CO)5(PPh3) (4) have been studied using the quantum theory of atoms in molecules (QTAIM) methodology. High-resolution X-ray diffraction data have been measured for compounds 2–4 at 100 K. The topological analyses show that only in compounds 1 and 4 is there any evidence for metal–metal bonding in terms of the presence of a bond path. For compound 1, the topology of the Fe2S2 cage is highly dependent on the Fe–Fe separation, and the deformation along this vector is an extremely soft mode. The experimentally observed topolog…
High-pressure transition to the post-barite phase in BaCrO4hashemite
2012
A recent high-pressure study on barium chromate BaCrO${}_{4}$ reported a phase transition but the structure of the high-pressure phase structure could not be identified. This high-pressure phase was suggested to have a monoclinic structure different from other high-pressure forms of $AB$O${}_{4}$-type compounds. In this work, we have carried out x-ray diffraction measurements up to 46 GPa using He as the quasihydrostatic pressure medium and density-functional theory calculations. Our studies allow us to identify the high-pressure phase as the $P$2${}_{1}$2${}_{1}$2${}_{1}$ post-barite-type phase, recently reported for BaSO${}_{4}$. The equations of state of both, the low- and the high-press…
La inseparabilidad y el grado de adaptación como determinantes de la internacionalización de las empresas de servicios
2005
-Esther.Sanchez@uv.es -Jose.Pla@uv.es La mayor parte de enfoques teóricos de internacionalización han surgido en el marco del sector industrial y, por tanto, algunas explicaciones podrían no ser generalizables al sector servicios en su globalidad. Por ello, las características sectoriales deben ser tenidas en cuenta en el análisis de los modos de entrada de las empresas de servicios, ya que es posible encontrar patrones de comportamiento muy diferentes no sólo con respecto a las empresas industriales sino también entre las propias empresas de servicios. En este trabajo se proponen la inseparabilidad de los servicios y el grado de adaptación a las necesidades del cliente como dimensiones cla…
Modes of innovation and differentiated responses to globalisation - a case study of innovation modes in the Agder region, Norway
2011
Published version of an article in the jounal: Journal of the Knowledge Economy. Also available from the publisher at: http://dx.doi.org/10.1007/s13132-011-0060-9 The main argument of this paper is that firms and industries are dominated by different innovation modes and that they therefore respond differently to challenges of globalisation. The paper differentiates between three modes: science, technology and innovation (STI), doing, using and interacting (DUI) application mode and the DUI technological mode. These innovation modes are based on different dominant knowledge bases, modes of learning and external knowledge. What is the implication of these differences with regard to competing…

Quasi-Normal Frequencies in Open Cavities: An Application to Photonic Crystals
2005
The electromagnetic field in an optical open cavity is analyzed in the framework of the Quasi-Normal Modes theory. The role of the complex quasi-normal frequencies in the transmission coefficient and their link with the density of quasi-modes function is clarified. An application to a quarter-wave symmetric one-dimensional photonic crystals is discussed to illustrate the usefulness and the meaning of our results.
