Une approche structurelle pour la reconnaissance de notices bibliographiques

1995

National audience; Cet article présente un système de reconnaissance de la structure logique de notices bibliographiques en vue de la conversion rétrospective de catalogues de bibliothèques. Le système est guidé par un modèle de structures de la classe des notices, construit sur la base de spécifications détaillées par la bibliothèque. Le modèle fait intervenir aussi bien des connaissances sur la macro-structure des notices que sur la micro-structure de leur contenu. La reconnaissance de la structure d'une notice consiste à retrouver, à partir d'un flux OCR (Optical Character Recognition), sa structure logique spécifique, conformément aux descriptions du modèle. Le résultat est un flux stru…

Quasi order, pseudo order and not order

1995

This study, after having presented the structure of total semi-order and that of pseudo-order one, presents a new preference structure called non order. This one generalizes both the semi-order structure and the pseudo-order one. The details analysis are based on the usual concepts of the relationnal approach of preference modelling and on some new concepts and principles which fit the imprecise context. These new principles are : imprecise discriminant power, imprecise transitivity, imprecise intransitivity and generalized limited comparability. The new concepts are : preference relationnal constituent and preference relationnal state.

Treatment of advanced pancreatic cancer with 5-fluorouracil, folinic acid and interferon alpha-2A: results of a phase II trial.

1995

Interferon alpha-2a (IFN-alpha) and folinic acid (FA) have been shown to modulate the cytotoxic effects of 5-fluorouracil (5-FU) in the treatment of cancer. A phase II study was initiated to evaluate the effect of a combination of 5-FU/FA/IFN-alpha in patients with advanced pancreatic cancer. Sixty previously untreated patients with advanced adenocarcinoma of the pancreas were treated with 500 mg m-2 FU via an intravenous bolus 1 h after the initiation of a 2 h infusion of 500 mg m-2 FA. Before starting the FA infusion, 6 million units (MU) of IFN-alpha was administered subcutaneously. The treatment was repeated once a week. Of 57 evaluable patients, eight (14%) had a partial response (PR),…

Retrobulbar anesthesia complicated by combined central retinal vein and artery occlusion and massive vitreoretinal fibrosis.

1995

Retrobulbar anaesthesia is routine procedure in ocular surgery. Complication are infrequent but often severe, involving both retina and the optic nerve. we report a case of combined central retinal vein and artery occlusion, secondary to retrobulbar anaesthesia, which evolved into retinal ischemia and Vitreoretinal fibrosis. This is the first time to our knowledge that such a dramatic evolution of post traumatic retinal occlusion has been reported.

University Hospital Fire Disaster — Lessons to Learn

1995

Reports on hospital fire disasters are only rarely published in medical journals, and then only in journals dealing with fire fighting or hospital management. Blumenhagen found only two English language articles published between 1977 and 1987, according to which 24 500 severe events were registered in the USA, equalling three events per institution per year. However, only 30–40% of these events were reported to the fire department. In the USA only 11% of all registered events caused damage amounting to more than US$ 1 000 000.

Risk of Bacillus cereus and Pseudomonas aeruginosa nosocomial infections in a Burns Centre: the microbiological monitoring of water supplies for a pr…

1995

This paper reports on an extensive epidemiological survey of the microbiological monitoring of the environment, staff, and patients in the Intensive Care Unit of the Palermo Bums Centre (Italy). The aim of the survey was to evaluate the presence and distribution of environmental sources of pathogens and opportunistic bacterial agents of nosocomial infection in immunocompromised hosts. Strains collected from air, tap water, and medical and nursing staff were compared with strains isolated from burn patients in order to study the potential transmission route of bacteria. The results showed environmental strains presenting a profile identical to that of the clinical strains, suggesting a link …

Efectos de la información acerca del ciclo menstrual sobre las actitudes hacia la menstruación

1995

El objetivo del estudio es analizar los efectos del acceso a una información adecuada relativa a la menstruación sobre las actitudes hacia ésta. Se realizaron comparaciones entre dos grupos de 8 mujeres, uno de los cuales recibe una charla informativa sobre el ciclo menstrual y el otro recibe una charla placebo. La actitud se mide mediante una versión modificada del Menstrual Attitude Questionnaire (MAQ). Se controla la influencia de los síntomas menstruales, medidos con el Menstrual Distress Questionnaire (MDQ). Las medidas se obtienen inmediata­mente después de recibir la charla y un mes más tarde. El grupo que recibe charla informativa muestra una actitud significativamente más positiva …

Digestion-free determination of heavy metals (Pb, Cd, Cu) in honey using anodic stripping differential pulse voltammetry and potentiometric stripping…

1995

Experiments have been carried out to assess the potential of differential pulse voltammetry and potential stripping analysis for determining Pb, Cu and Cd directly in dissolved honey samples using a flow-through cell. With the hanging mercury drop electrode Pb alone can be determined only if the electrode is first modified in-situ with Triton X 100 to increase the separation between the Pb peak and a broad, interfering adsorption peak which overlaps the Cu peak. If the (more sensitive) thin film mercury electrode is used the interference encountered is less so also Cu and Cd can be determined. With potentiometric stripping analysis Cu and Pb can be determined using normal procedures. The de…

Fragestellung, Forschungsstand und methodische Probleme

1995

In der empirischen Sozialforschung werden Kenntnisse, Meinungen, Einstellungen und Verhaltensweisen unterschieden. Unter Kenntnissen werden Sachinformationen verstanden, die richtig oder falsch sein konnen. Unter Meinungen versteht man wertende Stellungnahmen zu Meinungsobjekten (Konzepten), die nicht wahrheitsfahig sind. Unter Einstellungen versteht man dauerhafte Dispositionen genereller Art, die Meinungen und Verhaltensweisen im konkreten Fall beeinflussen konnen (Ajzen u. Fishbein 1980; Sample u. Warland 1973). Als Verhaltensweisen bezeichnet man beobachtbare Aktivitaten. Einstellungen sind im Unterschied zu Kenntnissen, Meinungen und Verhaltensweisen keine vorgegebenen Grosen. Es hande…

Two-body Mechanisms in Pion Scattering and Pion Photoproduction on the Trinucleon

1995

A breakdown of the Impulse Approximation is studied in pion photoproduction and pion charge exchange on 3He at high momentum transfers. The usual DWIA formalism with Faddeev wave functions which works well for small momentum transfers deviates from experimental measurements by up to two orders of magnitude for Q 2 > 6 fm−2. It is found that the explicit inclusion of two-body mechanisms, where the photon or pion is absorbed on one nucleon and the pion is emitted from another nucleon removes most of the disagreement with the data.

Λ Decay Induced by Two Nucleons

The decay of Λ hypernuclei induced by two nucleons is revised, along with its implications in the experimental determination of the ratio of neutron- to proton-stimulated Λ decay.

Characterization of sulfobetaine monomers by nuclear magnetic resonance spectroscopy: a note

1995

A set of zwitterionic monomers bearing the 3-ammoniopropanesulfonate moiety is analysed in CDCl3, CD3OD and D2O by one- and two-dimensional H-1 n.m.r. and C-13 n.m.r. spectroscopy. Absolute and relative positions of the n.m.r, signals are determined depending on the solvent used; the refined assignments of the signals in the vicinity of the ammonium group deviate from previously proposed assignments based on standard n.m.r, shift tables. Still, there is no convincing evidence for a special ring current effect due to a six-membered ring conformation of the betaine moiety.

Large Hardy-Weinberg equilibrium deviations in the Daphnia longispina of Lake El Tobar

1995

The population structure of Daphnia longispina in Lake El Tobar, Spain was studied by measuring variation at the aldehyde oxidase (AO), phosphoglucose isomerase (PGI) and phosphoglucose mutase (PGM) loci in each of 1337 individuals from four collections. In 9 of the 12 comparisons between observed allele frequencies and those expected by Hardy-Weinberg equilibrium there was an excess of heterozygotes. We found 27 of the potential number of 54 composite electromorphs (‘clones’) based on the three allozymes. Clone diversities were rather high in all collections. Three clones reached frequencies of over 25% and different clones were dominant in each of the four collections. Strong temporal var…

Platelet membrane fluidity and platelet membrane lipid pattern in essential hypertension

1995

In a group of subjects with essential hypertension platelets were studied in resting conditions: platelet membrane fluidity was measured with the fluorescent probe 1.4-(trimethylamino)-phenyl-4-phenylhexatriene (TMA-DPH), platelet membrane cholesterol/phospholipid ratio was evaluated separating the membrane lipids with column chromatography, and platelet membrane individual phospholipids were determined using two-dimensional thin-layer chromatography. From the obtained results, it is evident that platelet membrane fluidity does not differentiate normals from hypertensives; platelet membrane cholesterol/phospholipid ratio is increased in hypertensives, while of the platelet membrane individu…

PRODUCTION CHARACTERISTICS OF K-0 AND LIGHT MESON RESONANCES IN HADRONIC DECAYS OF THE Z(0)

1995

An analysis of inclusive production of K0and the meson resonances K*±(892), ρ0(770), f0(975) and f2(1270) in hadronic decays of the Z0is presented, based on about 973,000 multihadronic events collected by the DELPHI detector at LEP during 1991 and 1992. Overall multiplicities have been determined as 1.962±0.060 K0mesons, 0.712±0.067 K*±(892) and 1.21±0.15ρ0(770) per hadronic Z0decay. The average multiplicities of f0(975) for scaled momentum, xp, in the range 0.05≤xp≤0.6 and of f2(1270) for 0.05≤xp≤1.0 are 0.098±0.016 and 0.170±0.043 respectively. The f0(975) and ρ0(770)xp-spectra have similar shapes. The f2(1270)/ρ0(770) ratio increases with xp. The average multiplicities…

The Role of Tumor Volume in ‘Reoxygenation’ upon Cyclophosphamide Treatment

1995

The effect of cyclophosphamide (CP) injection (60 mg/kg i.p., single dose) on volume growth and tissue oxygenation (pO2 distribution) was investigated in rat DS-sarcomas. CP was administered 4 days after subcutaneous (s.c.) tumor implantation (volume approximately 0.35 ml). Polarographic pO2 measurements were performed in the subcutis at the hind foot dorsum and in tumors 72 h after CP administration. The oxygenation status of these tissues was compared with that of saline-treated controls. CP-injection caused a mean growth delay of 11 days in DS-sarcomas and had no impact on the oxygenation status of the subcutis. In contrast, in s.c. growing DS-sarcomas the pO2 distribution improved signi…

Aproximació als contorns tonals del català central

1995

The present study provides a preliminary description of a wide variety of pitch contours in Central Catalan, and shows that the phonological framework developed by Pierrehumbert (1980) and her colleagues successfully accounts for their relevant intonational distinctions. Compared to English, Central Catalan seems to make use of a wider inventory of pitch accents, namely, H*, L*, !L+H*, L*+H, H+L*, H+!, H*+L, and L+H*+H (a summary of the pitch accent plus boundary tone combinations is given at the end). As the model predicts, the relative alignment of the H and L levels with respect to the accented syllable triggers intonational oppositions in Catalan. For example, the distinction between an…

FEEDING-HABITS OF YOUNG-OF-THE-YEAR GREATER AMBERJACK SERIOLA DUMERILI (RISSO, 1810) ALONG THE N/W SICILIAN COAST

1995

A survey was carried out from July to December 1992 in the Gulf of Castellammare (N/W Sicily) in order to study the feeding habits of juveniles of the greater amberjack Seriola dumerili. Stomach content analysis showed three different phases of predation during this period, depending on the size variation of the specimens. Cluster analysis suggested prey choice differed within three size groups. Class I (individuals up to 80 mm SL) feed mainly on the zooplankton community (Copepoda and Crustacea larvae). Class II (individuals ranging from 80 to 120 mm SL) represent a transition stage in which fish continue to feed on zooplankton, but benthic and nectonic items also become important. Class I…

Direct inverse voltammetric determination of Pb, Cu and Cd in some edible oils after solubilization

1995

The direct determination of traces of certain heavy metals in oils is possible after treatment of the methanolic sample solution with Lumatom (tetramethylammoniumhydroxide). For the inverse voltammetric determination, a flow through cell with a mercury film electrode is used. The results for the determination of Cu and Pb in some edible oils after solubilization agree well with those obtained using wet oxidative high pressure ashing.

Analysis of Invariant Chain Processing in 3 Day Cultured Rat Langerhans Cells

1995

MHC class II molecules, critical peptide binding elements involved in the presentation of exogenous antigen to T helper cells, are expressed constitutively by Langerhans cells (LC) within their epidermal microenvironment. Several studies in mouse and man demonstrated, that short term in vitro culture of LC entails remarkable functional and penotypic alterations, including a profound increase of class II elements exposed at the LC’s surface1. Biosynthetic analysis revealed a downregulation of class II synthesis during the culture period2,3. In recent work on rat LC we described the uncoupling of the coordinately regulated biosynthesis of class II and invariant chain proteins in the course of…
