How we compensate for memory loss in old age: adapting and validating the Memory Compensation Questionnaire (MCQ) for Spanish populations.
2012
Compensating entails using external strategies and mechanisms that help overcome or alleviate the decreasing memory function that comes with age. This study aims to adapt and validate the MCQ in the elderly Spanish population. A total of 403 elderly people aged between 65 and 92 in the city of Valencia (Spain) completed the questionnaire for the validation process. The factorial validity of the scale was tested using confirmatory factor analysis. The result showed a first order five-factor model with 23 items that met the criteria for model fit according to multiple fit indices. As a general conclusion, the adaptation into Spanish provided a reliable and valid measure of compensation in the…
Gravity Anomalies Over The Gongola Arm, Upper Benue Trough, Nigeria
2005
A regional gravity survey of the Gongola Arm of the Benue trough was carried out with the aim of determining structures of interest. The results of the gravity interpretation showed that the area of study is characterized by negative Bouguer anomalies that trend in the NE-SW direction and range in value from -75 to -15 mGal with an average of -42 mGal. A first order polynomial was used to approximate the regional anomalies in the area. The residual gravity anomaly map shows anomalies that range in value from -32 to +20 mGal. 2.5-D modeling of the residual gravity anomalies suggests that the area has a horst and graben structure, with the grabens being as large as 60 km in width and filled w…
COPING WITH PEACE AFTER A DEBACLE
2008
This article analyzes a situation when the war was actually over and society began to recover. The government faced a severe challenge after the war. These serious problems will be analyzed in the light of the Great Northern War (1700–1721). The plans of the central government to stabilize society will be analyzed, as will the different kinds of planning activities undertaken by the authorities. The critical nature of the situation led the government to concentrate solely on short‐term planning. The government had no proper strategies; there were just a couple of exceptions to this rule. Firstly, the problems in Finland were repeatedly concrete and tangible. This made them both easy to addr…
Drawing and Project at the VChUTEMAS. Graphic Interpretations
2019
The article deals with the graphic study of the project for the Kominern Palace designed in 1929 by Lidija Komarova, one of the students of the Russian Laboratories known by the acronym VChUTEMAS, founded in 1920 in Moscow. Strongly characterized by the revolutionary atmosphere that was delineating the artistic progress based on the synthesis of all the plastic arts, the Russian Laboratories attributed to the architecture a position of the first order, a perfect association between the scientific possibility and the art technique. The redrawing of this project allows to deepen the compositional principles of the new architectural formation of the Eastern European avant-garde, providing digi…
Analytical evaluation of first-order electrical properties based on the spin-free Dirac-Coulomb Hamiltonian.
2011
We report an analytical scheme for the calculation of first-order electrical properties using the spin-free Dirac-Coulomb (SFDC) Hamiltonian, thereby exploiting the well-developed density-matrix formulations in nonrelativistic coupled-cluster (CC) derivative theory. Orbital relaxation effects are fully accounted for by including the relaxation of the correlated orbitals with respect to orbitals of all types, viz., frozen-core, occupied, virtual, and negative energy state orbitals. To demonstrate the applicability of the presented scheme, we report benchmark calculations for first-order electrical properties of the hydrogen halides, HX with X = F, Cl, Br, I, At, and a first application to th…
An Ehrenfeucht-Fraïssé Approach to Collapse Results for First-Order Queries over Embedded Databases
2001
We present a new proof technique for collapse results for first-order queries on databases which are embedded in N or R>o. Our proofs are by means of an explicitly constructed winning strategy for Duplicator in an Ehrenfeucht-FraissE game, and can deal with certain infinite databases where previous, highly involved methods fail. Our main result is that first-order logic has the natural-generic collapse over {N,≤ ,+} for arbitrary (i.e., possibly infinite) databases. Furthermore, a first application of this result shows the natural-generic collapse of first-order logic over {R>o,≤,+} for a certain kind of databases over R>o which consist of a possibly infinite number of regions.
Synthesis and structure of the incomplete cuboidal clusters [W3Se4H3(dmpe)3]+, [W3Se4H3−x(OH)x(dmpe)3]+and [W3Se4(OH)3(dmpe)3]+, and the mechanism of…
2004
The novel incomplete cuboidal cluster [W3Se4H3(dmpe)3](PF6), [1](PF6), has been prepared by reduction of [W3Se4Br3(dmpe)3](PF6) with LiBH4 in THF solution. The trihydroxo complex [W3Se4(OH)3(dmpe)3](PF6), [2](PF6), was obtained by reacting [W3Se4Br3(dmpe)3](PF6) with NaOH in MeCN–H2O solution. The complexes [1](PF6) and [2](PF6) were converted to their BPh4− salts by treatment with NaBPh4. Recrystallisation of [1](BPh4) in the presence of traces of water affords the mixed dihydride hydroxo complex [W3Se4H2(OH)(dmpe)3](BPh4). The crystal structures of [1](BPh4), [2](BPh4) and [W3Se4H2(OH)(dmpe)3](BPh4) have been resolved. Although the [1]+ trihydride does not react with an excess of halide s…
Artistic value of audience index
2016
Una de las manifestaciones de la cultura actual es su tendencia a la horizontalizacion. Marcel Duchamp senalo ya hace casi un siglo esta realidad, que comenzo a materializarse en la esfera artistica con la industria cinematografica y que ha alcanzado su maxima expresion con la revolucion digital. Internet, ha venido a cambiar, o mejor, a demostrar de facto lo que algunos teoricos senalan desde hace decadas. Y es que las audiencias no son esa masa uniforme, pasiva, aislada y, por tanto, facilmente controlable por la Industria Cultural o por el poder politico o economico. En la sociedad telematica, la facilidad de acceso a la oferta y la saturacion informativa exigen una participacion al espe…
Higher-order polarizations on the Virasoro group and anomalies
1991
In a previous paper the authors showed that the space of (first order) polarized functions on the Virasoro group is not, in general, irreducible. The full reduction was explicitly achieved by taking the orbit of the enveloping algebra through the vacuum. This additional step provided the proper quantization in the “strong-coupling” domain 0<c≦1. In this paper we introduce the concept of “higher order polarization” as a generalization of that of polarization. We prove that the imposing of the additional (higher-order) polarization conditions is equivalent to the taking of the above-mentioned orbit. This demonstrates that the generalized (higher-order) polarization conditions suffice to obtai…
Some approximation properties of ( p , q ) $(p,q)$ -Bernstein operators
2016
This paper is concerned with the $(p,q)$ -analog of Bernstein operators. It is proved that, when the function is convex, the $(p,q)$ -Bernstein operators are monotonic decreasing, as in the classical case. Also, some numerical examples based on Maple algorithms that verify these properties are considered. A global approximation theorem by means of the Ditzian-Totik modulus of smoothness and a Voronovskaja type theorem are proved.
