El montaje como problema significante
1993
El montaje nos habla, en primer lugar, de una amalgama: afirmando la heterogeneidad de los componentes significantes, insistiendo en su diversa procedencia y su carácter incompleto, pone el acento en la doble operación del análisis y la construcción sin omitir la heterogeneidad. Por otra parte, ocupa con todo rigor el lugar de un sujeto, pero convirtiéndolo en un efecto de sujeto, en la medida en que aparece como dispositivo técnico en el vacío dejado por una figura antropomórfica. El montaje aparece, así, como el único sujeto de la enunciación del texto moderno y expreso abiertamente en su superficie; por otra parte, el montaje da buena cuenta de toqos estos ingredientes múltiples de la ob…
Singular distributed parameter systems
1993
The paper deals with the distributed parameter systems described by coupled partial differential equations with singular matrix coefficients. Initial-boundary-value problems are considered in the light of both singular 1d systems theory and the Fourier approach to distributed parameter systems. The method presented in this paper gives the possibility of determining acceptable initial-boundary conditions. An illustrative example is given.
HPLC determination of volatile phenols in wines
1993
An alternative to the traditional solvent extraction method used to extract and rapidly quantify ethyl-and vinylphenol and ethyl-and vinylgaiacol from wine is presented. The method is based on retention of volatile phenols on adsorbants. Among the tested resins, the most efficient, AG 2-X8 (anion exchange resin), worked as well with a synthetic solution as with wines. The percolation of clarified wine adjusted to pH 9 on this resin permits, in particular, the elimination of organic acids. Phenols are not eluted after rinsing the column with 1N HCl, but are eluted with methanol after this treatment. Good recovery (91 %) and good repeatability are observed. The eluate is directly analysed by …

The electronic field shift factor of the 4s2S1/2?4p2PJ transitions in CaII
1993
The isotope shifts (IS) of the resonance lines 4s2S1/2−4p2PJin CaII (seven isotopes) have been measured by fast ion beam collinear laser spectroscopy (FIBCLS) with non-optical detection of the resonant laser-ion interaction. The electronic field shift factorF was derived from the experimental IS via a King plot procedure using the mean square nuclear charge radii from muon spectroscopy andelectron scattering. TheJ-independent resultF=−283(6) Mhz/fm2 was obtained. TheF-value resulting from extensive many body perturbation theory (MBPT) calculations, recently performed by Martensson-Pendrill et al., is in excellent agreement with the experimental value, confirming the reliability of the MBPT …
Benzodiazepinrezeptordarstellung mit JOMAZENIL-SPECT
1993
Die Darstellung der Benzodiazepin-Rezeptordichte (BZD) mit der Single- Photonen-Emissions-Computertomographie (SPECT) wurde durch die Synthese des neuen Radioliganden JOMAZENIL ermoglicht. JOMAZENIL entspricht dem mit Jod-123 markierten Benzodiazepin-Antagonisten Flumazenil und zeichnet sich durch eine hochspezifische Bindung an zentralen BZ-Rezeptoren aus. Verdrangungsexperimente zeigten, das 90–110 Minuten p.i. ca. 80% der Aktivitat der spezifischen Bindung entsprechen [1].
Cytotoxic activity of Ciona intestinalis (Tunicata) hemocytes: Properties of the in vitro reaction against erythrocyte targets
1993
Hemocytes (effectors) of Ciona intestinalis showed a natural cytotoxic capacity (HCA) when assayed in vitro against erythrocytes (targets). Cytotoxic cells lysed, to a variable extent, rabbit (RE), human (A, B, O), guinea pig, and sheep (SE) erythrocytes. Hemocyte cytotoxic activity (HCA) assayed against SE is a calcium-dependent reaction, occurs rapidly (15-30 min), at 25-37 degrees C over a wide range of pH (5.4-8.0). Assays were carried out using: 1) the medium in which hemocytes were maintained, 2) the soluble portion of hemocyte lysates, and 3) debris prepared from hemocyte lysates. Results suggest that HCA is a cell-mediated process that requires effector-target cell contacts. Anti-SE…
Reconciling dark matter and solar neutrinos
1993
Abstract We present a simple model for neutrino dark matter in which neutrino masses arise radiatively and the solar neutrino data are explained via the MSW effect. The dark matter scale arises at the one-loop level with the MSW scale arises only in two loops. The model is compatible with all observational facts and allows observable ν e ν τ or ν μ ν τ oscillation rates in the laboratory if the limits from primordial big bang nucleosynthesis (BBN) are taken conservatively. In addition, it can be probed by searching for muon number violating processes such as μ → e + γ , and μ →3 e . These rates can well lie within the sensitivities of present experiments. Finally, if we ignore BBN limits we…

Phase composition of Fe-containing Langmuir-Blodgett layers after thermal treatment in a reactive atmosphere
1993
By the Langmuir-Blodgett technique, mono- and multilayers of ferric stearate were drawn onto silicon wafers. They were thermodesorbed in air at 250–300°C, and the layers formed in this way were found to consist of γ-FeOOH with defective stoichiometry. By heating in H2, the layers can be reduced to Fe2− and even to α-Fe. The latter is magnetically ordered and highly corrosion resistant. Chloride ions, however, induce fast corrosion. FeCl2, formed by this corrosion, is rather unstable and transforms to an Fe3+ phase. The high corrosion resistance of the metallic Fe layer is assumed to be due to its excellent homogeneity. The experiments were performed using XPS, AES, CEMS, and SEM.
Les ducs de Bourbon (de Louis II au connétable de Bourbon) : leurs pouvoirs et leur pouvoir
1993
Trois remarques préalables s'imposent : 1. Louis II a été le troisième duc de Bourbon. Pourtant il est le premier que l'on peut considérer comme un prince ; le grand seigneur se fait prince. 2. Dans les ouvrages que j'ai écrits ou dirigés sur l'Histoire du Bourbonnais, j'ai toujours considéré que le Moyen Age en Bourbonnais se prolongeait jusqu'aux années 1523 (fuite du connétable)-1527 (mort du connétable). Le connétable de Bourbon est un prince médiéval. Cela pouvait paraître original, il y...
A measurement of the mean lifetimes of charged and neutral B-hadrons
1993
The decays of B-hadrons have been reconstructed using the charged particles recorded in the DELPHI silicon microstrip detector. The sum of the charges of the secondaries determines the charge of the B-hadron parent. Some 232 114 multihadronic Z0 decays recorded during the 1991 run of LEP at centre-of-mass energies between 88.2 GeV and 94.2 GeV yield 253 B-hadron candidates with well-measured charge. From these the mean lifetimes of neutral and charged B-hadrons are found to be 1.44 +/- 0.21(stat.) +/- 0.14(syst.) ps and 1.56 +/- 0.19(stat.) +/- 0.13(syst.) ps respectively. The ratio of their lifetimes is 1.09(-0.23)+0.28 (Stat.) +/- 0.11 (syst.). Under some assumptions on the abundance and …
Artroplastia unicompartimental de rodilla sin cementar: indicaciones y resultados
1993
Desde abril de 1987 hasta octubre de 1990, 100 pacientes (81 mujeres y 19 hombres) de 69 años de edad media fueron intervenidos mediante artroplastia unicompartmental de rodilla. El tiempo medio de seguimiento fue de 28 meses (rango: 12-48). La artroplastia fue indicada por osteoartrosis unicompartimental en 91 casos, necrosis aséptica femoral en 8 y destrucción post-traumática en 1. El implante utilizado era de tipo no constreñido y fijación sin cemento. En los primeros 12 meses de evolución, murieron 4 pacientes y otros 2 casos precisaron de reintervención, uno por aflojamiento de componente tibial y otro por luxación de ambos componentes. De los 94 pacientes restantes, 90 quedaron asinto…

De Caligari a Goebbels : Mabuse y el retorno del film demoníaco
1993
Romantic fantasy was one of the most important narrative and visual contributions of German cinema at the beginning of the 1920s. However, as the the decade progressed, this style was abandoned in favor of a growing realism and constructivist sets. The Testament of Doctor Mabuse marks a return to the realm of delirium which had characteried the beginnings of Expressionist cinematography as well as being the last work done in this style, as Nazismn was then on the rise. Most importantly, the film experiments with satanic characters and the transformation of the human voice.

The Significance of Stilbene-Type Phytoalexin Degradation by Culture Filtrates of Botrytis Cinerea in the Vine-Botrytis Interaction
1993
Phytoalexins, antimicrobial compounds, synthesized by a plant in response to infection or a variety of stresses are known to be the most efficient way by which grapevines withstand an attack by Botrytis cinerea Pers., the causal organism for grey mould. In that plant, such responses include the production of a simple stilbene, resveratrol, and the biosynthetically related compounds, viniferins and pterostilbene. If stilbene-type phytoalexins represent a contributory factor in the resistance of grapevines to B.cinerea, the capacity of the pathogen to metabolize antifungal compounds released by the host could also play a significant role in the outcome of the interaction between grapevines an…
Bone marrow after autologous blood stem cell transplantation and total body irradiation: magnetic resonance and chemical shift imaging.
1993
Magnetic resonance studies of the lumbar, pelvic, and femoral bone marrow were performed in 10 patients after autologous blood stem cell transplantation, including total body irradiation and myeloablative chemotherapy. The posttreatment interval varied between 2 and 6 yr. The appearance on T1-weighted images and the quantitative data obtained from chemical shift imaging (relative fat signal) were compared to 10 age-matched healthy volunteers. The classification of the T1-weighted images yielded no significant differences between the two groups. Chemical shift imaging by determination of the relative fat signal was able to detect a significant fatty replacement of the patients' lumbar (p < .…

Repercusiones fiscales de los decretos de Nueva Planta en la nobleza valenciana
1993
Entre los historiadores predomina la idea de que el triunfo borbónico en el conflicto sucesorio no afectó seriamente a las estructuras de dominio de la nobleza señorial valenciana, sino que, al contrario, ésta se vio beneficiada en un principio por la supresión del derecho foral y la implantación de la legislación castellana. Más aún, a veces la adscripción mayoritaria de la nobleza autóctona a las filas borbónicas se interpreta como una estrategia de afianzamiento de su privilegiada posición de dominio. Tanto es así que no parece que la centralización administrativa y política iniciada con los decretos de Nueva Planta pudiera haber dañado los intereses nobiliarios. El objeto de este artícu…
Exploring the Secret of Finnish Reading Literacy Achievement
1993
Abstract The article describes and analyzes the main findings of the International Association for the Evaluation of Educational Achievement (IEA) Reading Literacy Study in Finland. The initial analyses indicate that in the international comparison the Finnish students had the highest literacy levels at both 9 and 14 years of age among the 31 participating nations. Possible explanations for the high scores are suggested and discussed from both Nordic and national points of view. In order to relate the reading performance not only internationally but also to the previous assessments, the results on some subtests are compared with the corresponding tests in the 1970 IEA reading comprehension …

Politiques éducatives et conditions de l'objectif "80 pour cent d'une classe d'âge au niveau IV"
1993
International audience; L'objectif de conduire 80 pour cent d'une classe d'âge au niveau baccalauréat a été défini en 1985. Un certain nombre de mesures pédagogiques prises dès le début des années 60 ont permis l'expression de cet objectif en créant les conditions favorables de son développement. Cet article vise à reconstituer la complémentarité des mesures qui ont touché le collège, le lycée et la gestion de l'orientation pendant les trente années qui séparent le décret du 6 janvier 1959 portant la scolarité obligatoire jusqu'à 16 ans de la loi d'orientation sur l'éducation du 10 juillet 1989 donnant pour mission au système éducatif de qualifier tous les jeunes et d'en former 80 pour cent…

El Cuestionario de Ansiedad Laboral (C.A.L.). Resultados preliminares
1993
La aceptación de la naturaleza multidimensional de la ansiedad ha llevado a su abandono como una entidad explicativa unitaria. Las dimensiones de la ansiedad comprenden las interacciones entre el ambiente y el comportamiento cognitivo y/o fisiológico y/o motor, y dado que los tres sistemas interactúan entre sí, es necesaria la medición de las tres dimensiones. Sin embargo, en muchas investigaciones solo se ha medido uno de los componentes de la ansiedad, como ocurre en el ámbito de las organizaciones, en el cual frecuentemente solo se ha intentado medir uno de los componentes de la ansiedad laboral: el componente cognitivo o tensión. Además, la medida de la ansiedad laboral no está tan desa…
Oscillatory Reactions in Heterogeneous Catalysis
1993
Publisher Summary This chapter focuses on the oscillatory reactions in heterogeneous catalysis. Oscillations are possible on all levels in a catalytic reactor, from the single-crystal plane to the crystallite to the catalyst pellet to the packed-bed reactor, and each level adds another degree of complexity. So, it is necessary to isolate the major influences at each level and to separate the characteristics of the oscillations on one level from the effects caused by coupling with other levels. Only when each level is well understood is it possible to fully understand the overall oscillatory behavior. Oscillations in heterogeneous catalysis, therefore, remain an intriguing and demanding prob…
Monte Carlo methods for polymer chains in two - dimensional geometries (polymers at surfaces and interfaces)
1993
Coarse-grained models of polymers at interfaces can be defined such that their treatment by Monte Carlo simulation is most convenient and efficient for the problem at hand. This simulation strategy is briefly illustrated with three examples: (1) The orientational ordering of rigid rod-like polymers grafted to a surface, where “table methods” can be used, applying a fine discretization of the angles describing rod orientation. (2) Surface enrichment of one species in a polymer blend is treated by a semi-grand-canonical technique. (3) The number of configurations and structure of a star polymer attached with its center to a wall is studied by a “growth technique” generalizing simple sampling …
MEASUREMENT OF THE TAU-POLARIZATION AT THE Z-RESONANCE
1993
Using 18.8 pb-1 of data collected in 1990 and 1991, ALEPH has measured the tau polarisation in the decay modes tau-->enunuBAR, tau-->mununuBAR, tau-->rhonu tau-->a1nu, using both the individual tau decay kinematics and the event acollinearity. The measurement of the tau polarisation as a function of the production polar angle yields the two parameters A(tau) and A(e), where A(l) = 2g(V)l g(A)l/[(g(V)l)2 + (g(A)l)2]. The results A(tau) = 0.143 +/- 0.023 and A(e) = 0. 120 +/- 0.026 are consistent with the hypothesis of electron-tau universality. Assuming universality yields a measurement of the effective weak mixing angle sin 2theta(W)eff = 0.2332 +/- 0.0022.
