Entramado dialógico y rasgos morfosintácticos en un texto caribeño del siglo XVIII
1994
This article is an attempt of applying the conversational analysis to planned texts through a Caribbean work of the 18th. century called Historia de la conquista de la isla española de Santo Domingo. Trasumtada el año de 1762, del autor dominicano Luis José Peguero. It has been tried to systematize in the conversational analysis a series of elements which characterize the spoken language. This language belongs to a written text which gathered the basic structures and patterns managed in the communicative fact by the speakers, through the intuition of the writer-speaker in which J. L. Peguero became, to transmit his message to his workers.This approach omits the barely socio-linguistical ana…

Adaptationen der Primaten
1994
Kennzeichnende Merkmale des Schadels sind die Lagebeziehung1 und das Grosenverhaltnis des Gesichtsschadels (Viszerokranium)2 zum Hirnschadel (Neurokranium; Ubersicht in Delattre u. Fenart 1956; Biegert 1957; Hofer 1960, 1965; Moss u. Young 1960; C. Vogel 1966b3; Shea 1985, 1988). Bei fast allen Primaten liegt das Viszerokranium nicht mehr in der direkten Verlangerung des Neurokraniums (orthokranialer Schadel; Hofer 1965; Abb. 4.1), sondern er ist unterschiedlich stark gegenuber der Schadelbasis gesenkt (dekliniert), so das daraus ein klinorhyncher Schadel entsteht (Hofer 1965; Abb. 4.1). Beim Orang-Utan ist der Gesichtsschadel gegenuber der Schadelbasis etwas nach superior rotiert, so das e…
Fourier-Accelerated Polymer Dynamics
1994
Fourier acceleration methods are applied to simulations of two-dimensional isolated ring polymers of up to N = 64 monomers. Three simulation schemes are compared: (i) a simple Langevin simulation with local updating, (ii) a Langevin algorithm with Fourier acceleration, and (iii) a Fourier accelerated Langevin algorithm combined with Metropolis acceptance of the moves (Force Biased Monte Carlo). In contrast to (i) and (ii), method (iii) is not hampered by systematic discretization errors, which, in case (ii), seem to grow systematically with chain length N. The results on the correlation time 4 are not very accurate, however, the data are in rough agreement with τ s N z with z= 2.5 (Rouse mo…
Analysis of the incoherent intermediate scattering function in the framework of the idealized mode-coupling theory: A Monte Carlo study for polymer m…
1994
In this Monte Carlo simulation, we calculate the incoherent intermediate scattering function ${\mathrm{\ensuremath{\varphi}}}_{\mathit{q}}^{\mathit{s}}$(t) for a three-dimensional dense polymer melt after having made long relaxation runs in order to eliminate the history of the cooling procedure sufficiently. This function shows the signature of a two-step process in the temperature interval T\ensuremath{\in}[0.16,0.21] (the temperature is measured in units of an energy parameter introduced in the Hamiltonian of the model) whose time evolution was quantitatively analyzed in the framework of the idealized mode-coupling theory (MCT) within the \ensuremath{\beta}-relaxation regime. As a result…

Respuesta ósea al implante del compuesto beta-fosfato tricálcico-colágeno (ß-ftc-c). Estudio «in vivo» en conejos
1994
Se ha estudiado la correlación entre los hallazgos histológicos y las imágenes radiológicas de un compuesto de beta-fosfato tricálcico y colágeno (ß-FTC-C) después de su implantación en defectos óseos creados experimentalmente en 21 conejos de 4 Kg de peso medio. Bajo anestesia general los defectos óseos creados en ambos fémures se rellenaron con un cilindro de 4,5 x 6 mm del compuesto. Los animales fueron sacrificados a la semana y 1, 2, 4 y 12 meses del postoperatorio. Las muestras obtenidas fueron sometidas a estudio radiográfico e histológico. Microscópicamente se comprobó que el compuesto a lo largo del período de implantación sufrió un proceso de reabsorción progresiva mediado por cél…

Pragmatic aspects of the translation of slang and four‐letter words
1994
Abstract The article discusses linguistic and societal attitudes to slang in Latvia and their relevance to its rendition in Latvian translations. For historical reasons, there is a wide gap between spoken and written colloquial layers in Latvian. Slang, and especially four‐letter words, function differently in Latvian compared to English, where they are used much more frequently and have lost their disturbing connotations. Accordingly, in Latvian translations they must be softened to achieve ‘similar effect’. Today, however, there is a clear‐cut tendency to liberalize the attitude towards slang and taboos, which can be explained by the recent radical changes in Latvian society. Direct trans…

Biodiversity and characterization of arbuscular mycorrhizal fungi at the molecular level
1994
Biodiversity within a biological group provides the basis for distinguishing members into genera and species according to taxonomic criteria, and between individuals within a species depending on more detailed differences at the genetic level. Diversity between species occurs after a genetic barrier has been created either by a geographic or genetic impedance of gene flow. Divergence can continue by nucleotide substitutions and by mutations in a broader sense (deletions, translocations, duplications), and resulting diversity can be evaluated at the molecular level and used as a phylogenetic character. Diversity at the subspecies level is a function of both mutation rates and gene flow betwe…
Anisotropic diffusion in etched particle tracks studied by field gradient NMR
1994
Etched particle tracks produced after heavy ion irradiation of polymer foils are used as model systems to test the performance of NMR in a newly developed ultrahigh magnetic field gradient system. The stimulated NMR echo decay of molecules diffusing in the channels, formulated in terms of the self part of the intermediate scattering function, is anisotropic and yields the form factor of the channels.
Prevalence of essential tremor: A door-to-door survey in Terrasini, Sicily
1994
As part of a door-to-door neuroepidemiologic survey, we investigated the frequency and distribution of essential tremor (ET) in a Sicilian municipality. During phase 1, we administered a screening instrument for tremor to 7,653 persons residing in Terrasini (Palermo province). During phase 2, neurologists evaluated those subjects who had screened positive. The diagnoses, based on specified clinical criteria, were reviewed to increase reliability across neurologists. We found 31 subjects affected by ET (17 men, 14 women); 11 patients (35.5%) reported a familial aggregation. The prevalence of ET as of November 1, 1987, was 405.1 per 100,000 for the total population, and 1,074.9 per 100,000 fo…

A Review on mesonic decay of Lambda hypernuclei
1994
A review of the present situation of the mesonic decay of Lambda hypernuclei is done. The link between the propagator method and the one with wave functions and nuclear matrix elements is established. The lack of links between the mesonic decay and the nucleon occupation number in nuclear matter is also;discussed, as well as the effect of the Lambda N short range repulsion in the mesonic decay of light hypernuclei. The relevance of the 2p2h induced Lambda decay channel is also discussed. Finally an overview of the potential use of the process, when systematic measurements over the periodic table are done, is presented at the end.
Luxación inveterada del codo en niños: a propósito de un caso
1994
La luxación no reducida del codo es rara y no suele verse en los países desarrollados, salvo en grupos sociales marginados y de forma excepcional. La luxación más frecuentemente es posterior. Entre las 3 semanas y 3 meses, el tratamiento cerrado suele fracasar puesto que la interposición de tejido de granulación y fibroso intraarticular y la retracción de los tejidos blandos, impiden una reducción incruenta y estable. Nosotros recomendamos para luxaciones inveteradas, vistas en este período de tiempo, el abordaje posterior con sección del tendón del músculo tríceps y la reconstrucción de estructuras blandas periarticulares. Presentamos el caso de un niño tratado mediante reducción quirúrgic…
Aloinjerto como material de relleno de defecto óseo metafisario en las fracturas de platillo tibial
1994
El propósito de este estudio fue valorar la eficacia del aloinjerto en las fracturas de platillo tibial como material de relleno para los defectos metafisarios, así como una alternativa que disminuya la morbilidad (dolor en el lugar de la extracción, infección del mismo, alargamiento del tiempo de intervención quirúrgica...) sin que disminuya la capacidad de integración ósea y se comprometa la realización de una movilización precoz. Para ello se han revisado trece casos clínicos en los que se ha practicado una reducción anatómica, fijación interna y relleno con aloinjerto procedente del Banco de Huesos, apreciándose una integración ósea del mismo en el plazo aproximado de 10 semanas. Valora…
Interfacial tension and interaction parameters
1994
In view of various contradictory theoretical equations relating the interfacial tension σ between phase-separated polymer solutions to the Flory-Huggins interaction parameter of the system, the idea that σ should depend on the extent of the ‘hump’ in the concentration dependence of the Gibbs energy of mixing was studied. This investigation is based on 12 series of σ( T ) measurements reported in the literature and on additional experiments for the system cyclohexane/polystyrene. To quantify the extent of the ‘hump’, a reduced ‘hump energy’ ɛ was introduced and its value calculated for different temperatures from the measured critical data of the systems. The analysis of the entire experimen…
De la préprofessionnalisation à l'entrée à l'IUFM : parcours et orientation vers le professorat des écoles
1994
Cet article étudie l'influence de la préprofessionnalisation et de l'allocation d'année préparatoire sur les inscriptions à l'IUFM, dans le cadre de l'université de Bourgogne. Cette influence est d'abord appréhendée en termes d'effectifs : une majorité d'étudiants admis à l'IUFM a suivi l'option de prépro. D'un point de vue plus qualitatif, le profil de formation est largement dominé par la filière sciences humaines. L'attrait de la pré-formation et du pré-recrutement est confirmé par des entretiens avec quelques étudiants de l'IUFM qui témoignent parallèlement de leurs motivations pour l'enseignement.

Tratamiento artroscópico de las lesiones meniscales estudio retrospectivo de 484 casos
1994
Se analizan retrospectivamente 484 procedimientos artroscópicos realizados entre 1980 y 1993, en los que se encontró patología meniscal. La edad de los pacientes estudiados osciló entre los 6 a los 77 años (media de 37). En 447 casos la lesión afectó a un solo menisco. El menisco interno fue el más afectado (344 vs 167). La edad media de las lesiones traumáticas (30 años) fue menor que la de las degenerativas (50 años), ocupando las complejas —lesiones mixtas de difícil explicación etiológica— una posición intermedia (40 años). El daño del cartílago fue la lesión asociada más frecuente, observándose hasta en un 64% afectación del compartimento femoropatelar. El 25% presentaron lesiones del …
Is Written Language Production more Difficult than Oral Language Production? A Working Memory Approach
1994
Abstract Is written language production more difficult than oral language production? Probably, yes. But why? Several experiments were conducted in order to test the impact of low-level activities involved in writing on the performance of higher-level activities also involved in writing. Three assumptions were made: (1) the capacity of working-memory is limited, (2) every component of writing has a cognitive load, and (3) every increase in the load devoted to the activity of one component would lead to a decrease in the remaining resources available for the other components. These low-level activities are more resource-consuming in children than in adults because children have not yet autom…
Determination of triamterene in urine by HPLC using fluorescence detection and column-switching
1994
A liquid chromatographic method incorporating column-switching and fluorimetric detection for the determination of triamterene in untreated urine, is described. The urine samples (5 μL) were directly introduced onto an Hypersil ODS-C18, 30 μm (20 mm×2.1 mm I.D.) pre-column. Polar urinary compounds were removed by flushing the pre-column with water for 1 min, and the analyte was then switched onto an HP-LiChrospher RP C18,5 μm (125 mm×4mm ID) analytical column using an acetonitrile/phosphate buffer gradient elution. Fluorescence detection was performed at 230 nm excitation and 430 nm emission wavelengths. The recovery of drug was 102±2% in the 0.10–20.0 μg/mL concentration range, the limit o…
Oxygen regulated gene expression in facultatively anaerobic bacteria
1994
In facultatively anaerobic bacteria such as Escherichia coli, oxygen and other electron acceptors fundamentally influence catabolic and anabolic pathways. E. coli is able to grow aerobically by respiration and in the absence of O2 by anaerobic respiration with nitrate, nitrite, fumarate, dimethylsulfoxide and trimethylamine N-oxide as acceptors or by fermentation. The expression of the various catabolic pathways occurs according to a hierarchy with 3 or 4 levels. Aerobic respiration at the highest level is followed by nitrate respiration (level 2), anaerobic respiration with the other acceptors (level 3) and fermentation. In other bacteria, different regulatory cascades with other underlyin…

Production of halogenated compounds by Bjerkandera adusta.
1994
International audience; The white-rot fungusBjerkandera adusta produces volatile chlorinated phenyl compounds. The main compounds identified were 3-chloro-4-methoxybenzaldehyde (3-chloro-p-anisaldehyde), 3-chloro-4-methoxybenzyl alcohol (3-chloro-p-anisyl alcohol), 3,5-dichloro-4-methoxybenzaldehyde (3,5-dichloro-p-anisaldehyde), and 3,5-dichloro, 4-methoxybenzyl alcohol (3,5-dichloro-p-anisyl alcohol).p-Anisaldehyde, veratraldehyde and the corresponding alcohols,p-anisyl alcohol and veratryl alcohol were produced simultaneously. Even with a very low concentration of chloride in the medium (<>–5 m), chlorinated aromatic compounds were still observed. Addition of bromide to the culture mediu…
Spontaneous plaque rupture visualized by intravascular ultrasound.
1994
An intravascular ultrasound examination was performed in order to evaluate an angiographically complicated lesion. Intravascular ultrasound was able to demonstrate spontaneous plaque rupture in a patient with recent acute subendocardial infarction. The inconclusive angiographic appearance was clarified by the intravascular examination and led us to conclude that the myocardial infarction was due to plaque rupture with subsequent thrombotic occlusion, which had spontaneously resolved by the time of the study.
