Spatial spillovers in France: a study on individual count data at the city level
2007
Our study aims to measure the effects of spatial R&D spillovers on firms' patent production at the city level. We use an original method to estimate the spatial dimension of spillovers using count data. The method, based on a generalized cross entropy approach, allows us to test spatial auto-correlation. The main result is that when there are local spillovers, their impact on knowledge production is different according to the geographical area and the sector.

Hétérogénéité spatiale : principes et méthodes
2004
Spatial Heterogeneity : Principles and Methods This article has a dual purpose . First , it describes the main econometric specifications which can be used to represent spatial heterogeneity , reflected in an instability of parameters in space and / or a heteroscedasticity of error terms . Only the specifications valid in cross-section are examined . Second , it explains the links between spatial heterogeneity and autocorrelation , the other major feature of localised data , defined by the absence of independence between geographical observations . In particular , we look at the extent to which traditional tests of heteroscedasticity or instability need to be amended to take account of spat…
Projekts: Uzņēmuma "Instrumenti" jaunās struktūrvienības izveidošana
2022
Projekta “Jaunās struktūrvienības izveidošana SIA Instrumenti” ideja ir pastāvošam uzņēmumam, kurš nodarbojas ar palīgmateriālu, ķimikālijas, instrumentu auto un celtniecības nozares profesionāļiem, tiešo pārdošanu, izveidot jaunu struktūrvienību – mazumtirdzniecības veikalu. Uzņēmums “Instrumenti” pastāv tirgū jau 15 gadus un saskaņā ar finanšu pārskatiem, uzņēmumam pēdējos trīs gados pārdošanas apjoms neattīstās. Atverot mazumtirdzniecības veikalu, uzņēmums varēs paplašināt savai produkcijai noietu, palielināt zīmola atpazīstamību, iegūt jaunus klientus, palielināt pārdošanas sortimentu jau pie esošajiem klientiem, palielināt apgrozījumu. Klientiem veikals palīdzes atrisināt preču iepirku…
La inscripción de la ciudadanía en la cuba neocolonial (1902-1919) : Sucinta referencia histórico-jurídica
2021
This historical-legal account brieflycovering 17 years of civil registration activity carried out during the neocolonial period by Municipal Judges and Secretaries, specifically that related to registration of Cuban citizens)becomes considerably relevant to understand and to godeeper into the origins of this complex process, as well asto achieve a re-encounter with the history of those who passed through those times, currently a hidden history in the shadows of Civil Registration offices, but still alive and thus allowing us to find all the beauty that there was in it.
Pd2Au36(SR)(24) cluster: structure studies
2015
The location of the Pd atoms in Pd2Au36(SC2H4Ph)(24), is studied both experimentally and theoretically. X-ray photoelectron spectroscopy (XPS) indicates oxidized Pd atoms. Palladium K-edge extended X-ray absorption fine-structure (EXAFS) data clearly show Pd-S bonds, which is supported by far infrared spectroscopy and by comparing theoretical EXAFS spectra in R space and circular dichroism spectra of the staple, surface and core doped structures with experimental spectra.
Charge radius changes of even-even neutron-rich Tellurium isotopes
2005
Laser spectroscopy based on resonant ionization of laser-desorbed atoms has been used to study the neutron-rich tellurium isotopes with the COMPLIS facility at ISOLDE-CERN. The isotope shift and the hyperfine structure of several neutron-rich Te isotopes: $^{120–136}$Te and $^{123m–133m}$Te have been measured. From the hyperfine structure and the isotope shift we can extract the magnetic and quadrupole moments and the change in the mean square charge radius respectively. The mean square charge radii of the even-even isotopes have been deduced and their comparison with the known data for the other elements near Z=50 is presented. The experimental $\delta$ is compared with that obtained from …
A Theoretical and Experimental Investigation of the Spectroscopic Properties of a DNA-Intercalator Salphen-Type ZnIIComplex
2014
The photophysical and DNA-binding properties of the cationic zinc(II) complex of 5-triethylammonium methyl salicylidene ortho-phenylenediiminato (ZnL 2 + ) were investi- gated by a combination of experimental and theoretical methods. DFT calculations were performed on both the ground and the first excited states of ZnL 2 + and on its possi- ble mono- and dioxidation products, both in vacuo and in selected solvents mimicked by the polarizable continuum model. Comparison of the calculated absorption and fluores- cence transitions with the corresponding experimental data led to the conclusion that visible light induces a two-elec- tron photooxidation process located on the phenylenediimi- nato…
Spectroscopic characterization of alkaline earth uranyl carbonates
2005
A series of alkaline uranyl carbonates, M[UO{sub 2}(CO{sub 3}){sub 3}].nH{sub 2}O (M=Mg{sub 2}, Ca{sub 2}, Sr{sub 2}, Ba{sub 2}, Na{sub 2}Ca, and CaMg) was synthesized and characterized by inductively coupled plasma mass spectrometry (ICP-MS) and atomic absorption spectrometry (AAS) after nitric acid digestion, X-ray powder diffraction (XRD), and thermal analysis (TGA/DTA). The molecular structure of these compounds was characterized by extended X-ray absorption fine-structure (EXAFS) spectroscopy and X-ray photoelectron spectroscopy (XPS). Crystalline Ba{sub 2}[UO{sub 2}(CO{sub 3}){sub 3}].6H{sub 2}O was obtained for the first time. The EXAFS analysis showed that this compound consists of …
