Densities, Viscosities, and Refractive Indices of Some Binary Liquid Systems of Methanol + Isomers of Hexanol at 298.15 K
1996
Viscosities, densities, and refractive indices of eight binary liquid systems containing ethanol + some isomers of hexanol have been determined at 298.15 K. The excess property values were fitted to the Redlich-Kister equation to estimate the binary coefficients and the standard deviations.
Classification of Chitinozoa (Llandoverian, Canada) Using Image Analysis
1996
Chitinozoa (Llandoverian, Canada) were studied using image analysis. After digitalization of the objects, shape parameters were calculated. The boundary of each fossil was then traced by a vector centred at the centroid for Fast Fourier Transform (FFT). Results of the two methods were used as variables in a hierarchical cluster analysis in order to group the samples. These results show that Chitinozoa can be significantly classified in terms of taxa using independent shape parameters obtained by image analysis.

Intraseasonal variations of June?September rainfall and upper-air circulation over Kenya
1996
In the Northern Summer, Kenya is located under the influence of the divergent Indian monsoon flow, and therefore is dry except for two separate areas: the coastal strip and the western regions. Analysis of daily rainfall data for June–September 1982 to 1988 has revealed that, although there are many distinct rainfall events between the two regions, an out-of-phase relationship is also evident, rain on the Coast being frequently accompanied by a drop in the precipitation over the Rift Valley area. It is shown that two types of wind forcing accompany these patterns. Alternating westerly and easterly anomalies at the 700 hPa level are associated with persistent wet and dry conditions (respecti…
Vulnerabilität für Schizophrenie: Entwicklung einer Modellvorstellung anhand von Familienstudien
1996
Vulnerabilitatsmodelle fur schizophrene und affektive Storungen gehen davon aus, das sowohl klinische Storungen als auch subklinische Varianten und Normabweichungen durch dieselben disponierenden Faktoren evoziert werden. Die Starke der Vulnerabilitat (Disposition) zu einer Storung bildet sich auf einer Dimension ab, die durch die additive Wirkung verschiedener Ursachenbedingungen determiniert wird; die verschiedenen Auspragungsstufen auf dieser Dimension drucken sich in unterschiedlichen, aber qualitativ ahnlichen Verhaltensmustern aus und zwar so, das mit steigender Vulnerabilitatsstarke auch die Devianz dieser Verhaltensformen zunimmt. Die maximale Auspragungsstufe dieser Vulnerabilitats…
The Zahorski theorem is valid in Gevrey classes
1996
Let {Ω,F,G} be a partition of R such that Ω is open, F is Fσ and of the first category, and G is Gδ . We prove that, for every γ ∈ ]1,∞[, there is an element of the Gevrey class Γγ which is analytic on Ω, has F as its set of defect points and has G as its set of divergence points.
Effects of selective phosphodiesterase inhibitors on platelet-activating factor- and antigen-induced airway hyperreactivity, eosinophil accumulation,…
1996
There is currently interest in the potential use of selective inhibitors of cyclic nucleotide phosphodiesterases (PDE) in the treatment of asthma. In this study we examined the effects of three selective PDE inhibitors, milrinone (PDE III), rolipram (PDE IV) and zaprinast (PDE V), on the broncoconstriction produced by antigen and histamine, the airway hyperreactivity and microvascular leakage after aerosol exposure to platelet-activating factor (PAF) and antigen, and the antigen-induced eosinophil infiltration in guinea-pig lung. Inhaled rolipram (0.01-10 mg ml-1) inhibited dose dependently the bronchospasm produced by aerosol antigen (5 mg ml-1) an anaesthetised, ventilated guinea-pigs. Ro…
Nouvelles données sur le genre Bragasellus (Crustacea: Isopoda: Asellidae
1996
From now on, the genus Bragasellus Henry & Magniez, 1968 includes 2 oculated and 17 stygobiotic species. As a natural and monophyletic taxonomic unit, we consider it a good genus. Its original area corresponds to the north-west quarter of the Iberian Peninsula. Secondarily, this area has extended eastward, using mainly the alluvial channels of hydrographic systems (Ríos Douro + Ebro and tributaries), finally reaching the underground waters of several Mediterranean rivers. This active expansion is exclusively due to the migration of two stygobiotic sibling species: B. lagari Henry & Magniez, 1973 towards the high basin of the Río Tajo, then downstream to the basins of the Ríos Jucar and Turi…

Introducció les eolianites de les Penyes de l'Albir
1996
Las eolianitas de les Penyes de l'Albir han inmovilizado un volumen de cerca de 16 hm sobre el flanco marítimo de la Serra Gelada en una secuencia cuaternaria de llamativas formas relictas donde interfieren procesos marinos, eólicos y propios de ladera. Parece haber pesado más la anchura y naturaleza de la plataforma marina que los repetidos cambios de nivel que apenas han dejado huella. Las dunas adosadas rampantes pertenecen a diversos sistemas -tres al menos- que tratamos de individualizar, así como unas formaciones encostradas de ladera muy significativas.
Steroid-growth factor interaction in human prostate cancer. 2. Effects of transforming growth factors on androgen metabolism of prostate cancer cells
1996
The ability of human prostate cancer cells to metabolize androgens was assessed through administration of physiological concentration (0.5-10 nM) of tritiated testosterone (T) as precursor and one-step analysis of both T degradation and products' formation by reverse-phase HPLC and on-line radioactive detection after either 24 h or 72 h incubation. Overall, different prostate cancer cells degraded T quite differently, favoring alternatively reductive or oxidative metabolic pathways. In particular, both LNCaP and DU145 cells retained high levels of unconverted T, with a limited production of androstenedione and its 17-keto derivatives and relatively high amounts of dihydrotestosterone (DHT) …

Linguistic Approaches to Negotiating Activity.
1996
One of the main concerns we often share as teachers and applied linguists, is how to approach certain conversational activities both as to what refers to their linguistic characterization and as to what concerns the pedagogic side of the teaching/learning of the activity at issue. What is established then at the outset is an existing link between language description and implementation of method(s). The study of negotiating activity is one such example, where the linguistic approach has undergone a series of shifts, which have largely influenced the learning/teaching approach to this conversational genre. It is our purpose in this article to review the processes that studies into negotiatin…
CQ*-algebras: Structure properties
1996
Some structure properties of CQ*-algebras are investigated. The usual multiplication of a quasi *-algebra is generalized by introducing a weak- and strong product. The *-semisemplicity is defined via a suitable family of positive sesquilinear forms and some consequences of this notion are derived. The basic elements of a functional calculus on these partial algebraic structures are discussed.

Isolation of Alkaloids from Cultured Hybrid Cells of Rauwolfia serpentina*Rhazya stricta.
1996
Two monoterpenoid indole alkaloids and four β-carbolines were isolated from a hydrid cell suspension culture generated from two Apocynaceous plants, Rauwolfia serpentina Benth. and Rhazya stricta Decaisne. This indicates that the function of alkoloid biosynthesis is retained after hybrid formation and that alkaloids not previously detected in the parental plants or cell cultures are formed.
“Small Volume Resuscitation” as Treatment of Cerebral Blood Flow Disturbances and Increased ICP in Trauma and Ischemia
1996
“Small volume resuscitation” (SVR) is a promising concept for the treatment of shock and trauma patients. SVR utilizes the fast infusion of a small volume of hypertonic saline to mobilize intraendothelial and parenchymal water to expand and restitute intravascular volume. Therefore it seems warranted to also consider SVR for the treatment of disturbances of the cerebral circulation and of increased intracranial pressure (ICP). The current study uses a rabbit model of global cerebral ischemia combined with mild hemorrhage to test SVR. Somatosensory evoked potentials (SEPs) serve as a short-term outcome parameter. The data demonstrate a beneficial effect on ICP, a better reperfusion, and an i…
Magnetic potential of transformer window
1996
We describe how to calculate the magnetic potential in the window of an ideal transformer. The knowledge of this potential is a starting point for the determination of some other quantities of practical importance (such as leakage field, overheating of windings, circular currents, additional losses, short circuit forces in windings, etc.).

Sobre las condiciones de la comprensión transcultural
1996
En la primera parte del artículo examino la interpretación que hace Karl O. Apel de varios textos de Peter Winch sobre el problema de la comprensión de culturas ajenas, distinguiendo aquellos aspectos de la crítica de Apel que me parecen plausibles de otros que considero infundados. En la segunda parte trato de demostrar que en la obra del último Wittgenstein hay elementos para una teoría de la comprensión transcultural libre de las limitaciones que Apel atribuye a Winch, pero a la vez enfocada desde una perspectiva naturalista diametralmente opuesta a la aproximación trascendental de Apel a la hermenéutica. The first part of the artícle considers Karl O. Apel's interpretatíon of various te…
Vestigios documentales de una fiscalidad recién nacida: Las "Generalitats" valencianas
1996
Durante los siglos finales de la Edad Media, una nueva fiscalidad nació en buena parte de Europa occidental como consecuencia del crecimiento experimentado por las necesidades pecuniarias de nuestros soberanos. Y el reino de Valencia no fue una excepción. En este artículo, sin embargo, no estudiaremos todo ese proceso de renovación fiscal, sino exclusivamente la forma que ese nuevo sistema fiscal adoptó en Valencia para recaudar el donativo concedido al rey Pedro IV por las Cortes de 1373-74.
Trabajo Social con poblaciones receptoras de inmigrantes: un modelo cuasi-experimental para fomentar actitudes multiculturales.
1996
Este artículo forma parte de un proyecto transnacional entre España, Portugal, Italia y Grecia, subvencionado por el Programa de Desarrollo Tecnológico del Gobierno Autonómico Valenciano, que tiene como objetivo el fomento de actitudes tolerantes hacia inmigrantes en el sistema educativo. Se ha diseñado un modelo llamado EUROSUR que, puesto a prueba a través de experimentación, obtiene resultados satístactorios. La hipótesis principal es que el factor conocimiento (información a través de tres vías: audiovisual, escrita y oral) es una variable independiente determinante para atenuar e incluso modificar en los jóvenes la configuración de prejuicios racistas ante los inmigrantes.

Zum Ausmaß der Radikalität beim Papillenkarzinom
1996
Bei 31 Patienten nach Pankreaskopfresektion wegen eines Papillenkarzinoms konnte gezeigt werden, das fur die Prognose das Ausmas der Lymphknotendissektion entscheidend ist. Eine alleinige Papillenexcision ist allenfalls bei Patienten im schlechten Allgemeinzustand nach lokaler Excision eines gut differenzierten PT1-Tumors der kleiner als 0,5 cm ist indiziert, falls das Risiko der Reintervention groser ist als das der Lymphknotenmetastasierung.
Can hydrophobic interactions be correctly reproduced by the continuum models?
1996
The ability of the continuum models to describe hydrophobic interactions is investigated. In this work we have studied the interactions between two methane molecules in aqueous solution by means of a continuum model. The resulting potential of mean force is in good agreement with those obtained using Monte Carlo and molecular dynamics techniques. The three energy contributions appearing in the continuum energy partition (electrostatic, dispersion−repulsion, and cavitation) have been analyzed. The cavitation free energy plays the most important role of the three, determining the existence of an energy barrier between the contact minimum and the separated methane monomers. This barrier, which…
