Quantitative versus qualitative Beurteilung der linksventrikulären Funktion — Praktikabilität und Limitationen
1993
Die Prognose des Patienten mit koronarer Herzkrankheit ist entscheidend von den Volumina des linken Herzens und der Ejektionsfraktion abhangig (17, 32). Ein nichtinvasiver Zugang zu diesen Parametern ist daher fur die Risikostratifizierung und Verlaufsbeurteilung unter Therapie von grosem klinischen Wert. Einen solchen Zugang bietet die zweidimensionale Echokardiographie. Seit ihrer Einfuhrung in die Klinik Ende der siebziger Jahre besteht jedoch eine noch immer andauernde Auseinandersetzung uber die Frage, ob es moglich ist, eine exakte Quantifizierung der linksventrikularen Funktion mittels zweidimensionaler Echokardiographie vorzunehmen, oder ob nur eine mehr qualitative Beurteilung mogl…

El yacimiento premusteriense de la Cova de Bolomor
1993
El estudio geomorfológico y sedimentológico del yacimiento premusteriense de la Cova de Bolomor, (Tavernes de Valldigna), permite conocer las características paleoambientales de esta zona del País Valenciano durante el Pleistoceno medio y comienzo del Pleistoceno superior. Los datos cronológicos contribuyen a situar la secuencia en un contexto temporal, así como a su correlación con los registros marinocontinentales del marco mediterráneo inmediato.
Determination of alpha(s) using the next-to-leading-log approximation of QCD
1993
A new measurement of alpha(s), is obtained from the distributions in thrust, heavy jet mass, energy-energy correlation and two recently introduced jet broadening variables following a method proposed by Catani, Trentadue, Turnock and Webber. This method includes the full calculation of O(alpha(s)2) terms and leading and next-to-leading logarithms resummed to all orders of alpha(s). The analysis is based on data taken with the DELPHI detector at LEP during 1991. I its found that the inclusion of the resummed leading and next-to-leading logarithms reduces the scale dependence of alpha(s) and allows an extension of the fit range towards the infrared limit of the kinematical range. The combined…

Pilot study of natural human interleukin-2 in patients with chronic hepatitis B
1993
Ten patients with chronic hepatitis B received increasing doses of nIL-2 (30 000 U, 100 000 U, 300 000 U, 1.0 million U) subcutaneously in a phase I trial. Each dose was applied once per week over 3 weeks. Serum samples were taken before and 2, 12, 24, 48 and 72 h after the first application of each dose level. Serum concentrations of interleukin-1 (IL-1), IL-2, IL-6, interferon-alfa (IFN- α ), IFN- γ , tumor necrosis factor- α (TNF- α ) and GM-CSF as well as the cytokine-dependent serum components neopterin, beta-2-microglobulin (B2M), C-reactive protein (CPR), soluble IL-2-receptor (sIL-2R) and 2′-5′-oligoadenylate synthetase (2–5 OA) were assayed using ELISAs and RIAs. None of the sample…
The effect of periodic bottlenecks on the competitive ability of Drosophila pseudoobscura lines.
1993
Competition experiments between several Drosophila pseudoobscura strains that were previously subjected to periodic bottlenecks of different sizes and D. willistoni have been carried out. Contrary to previous results with these two species, where stable coexistence was detected, populations of D. pseudoobscura displaced D. willistoni in a few generations. By using a relative fitness measure, the control lines (that had not gone through bottlenecks) outcompeted D. willistoni faster than bottlenecked lines. One of these, corresponding to the minimum possible bottleneck size of one pair, also shows significantly lower relative fitness than the other strains. These results are discussed in rela…

Rodolf Sirera i la renovació del tetre valencià
1993
The present article begins with a revision of theatrical development in País Valencià during the post-war period, and goes on to focus on the most important writer, Rodolf Sirera, whose production is presented organised in different moments. It finally offers an analysis of the text El verí del teatre as an example of the maturity and transgression of his dramatic discourse.
Aspects of Anglo-Spanish Perceptions and Product Preferences Arising From ‘Country of Origin’ Image
1993
This study investigates the incidence and importance of ‘country of origin’ for a wide range of products made and marketed across Europe. How important is the ‘country of origin’ effect in shaping purchasing behaviour? Is it equally significant for every country and every product? Of crucial importance for the future as new offshore production locations open up in southern and eastern Europe is the question, to what degree is the ‘made in’ effect country specific and how durable is it? For example, can a company that has achieved global marketing stature based primarily on exports retain its ‘country of origin’ marketing edge when it graduates to producing its products in the heartland of i…
Angiographien im Kleinkindes- und Kindesalter
1993
Between 1973 and 1991 we performed 160 percutaneous angiograms (130 arteriograms, 30 phlebograms) in children and infants; 12 patients were less than one year and 52 less than ten years old. 44 of the examinations were done by a DSA technique. The examinations were carried out under general anaesthesia except in 8 cases. In 50.7% an arteriogram was carried out for the investigation of a suspected or known tumour, in 9.3% an arteriogram was required following trauma. The most common phlebographic examination was for the demonstration of the spermatic vein; in 27 patients this was done for cryptorchidism or a varicocele. The only complication following a diagnostic angiogram was perforation o…

Money, "finance" and interest
1993
The purpose of this paper is to show that there is no such thing as a pure money interest in the usual meaning of the phrase, that is, interest bearing on pure bank money. Basically, money cannot bear interest because it is not a net asset. This does not however imply that banks cannot charge interest on liquidities they have created. The concept of "finance" brings to light the process through which a liquid capital owned by the banks is formed in the economy. It then becomes clearer that what is commonly called "money interest" paid to banks is in fact a macroeconomic cost of production and therefore a net asset for the whole of the economy, including the banks.

Dissymmetric calix[4]arenes: Optical resolution of some conformationally fixed derivatives
1993
Various possibilities to obtain intrinsically chiral calix[4]arenes are discussed. The enantiomers of three 1,3-dietheresters and one monoether compound derived from dissymmetric calix[4]arenes with C4 symmetry were separated by HPLC using chiral stationary phases and characterized by their CD spectra. © 1993 Wiley-Liss, Inc.
The Drell-Hearn-Gerasimov sum rule and the constituent quark model
1993
The helicity structure function of the nucleon has been calculated for the constituent quark model and compared to the prediction of the Drell-Hearn-Gerasimov sum rule. The multipole decomposition of the sum rule shows large cancellations between different resonances. The small isoscalar-isovector contribution is related to the admixture of aD-state (“bag deformation”) in the nucleon's wave function. The calculations indicate a relatively slow saturation of this part of the sum rule with excitation energy.
A new heterogeneous and reconfigurable architecture for image analysis
1993
In the paper a new architecture for image analysis: HERMIA (Heterogeneous and Reconfigurable Machine for Image Analysis) is presented. It has bt:en developed at the University of Palermo, inside the Progetto Finalizzato of the ltalian Council of Researches (CNR): Sistemi informatici e Calcolo Parallelo. The architecture of the HERMIA-machine is reconfigurable, moreover the integration of heterogeneous module, oriented to the solution of specific problems, allows to salve complex problems by search of optimal strategies. Signa! processing units allows the user to handle and integrate multi-sensors signals (from video, scanner, music recorder). Here the generai architecture, the hardware impl…
Ultrastructural causes of rupture of hand tendons in patients with rheumatoid arthritis. A transmission and scanning electron microscopic study.
1993
To identify the cause of rupture of hand tendons in patients with rheumatoid arthritis, we studied the underlying ultrastructural changes of the collagenous fibril systems. Samples of the flexor digitorum superficialis (n = 12) and the extensor digitorum communis (n = 20) were taken during tenosynovectomy. Tendons dissected at necropsy (n = 30) served as controls. Specimens were analysed by transmission and scanning electron microscopy. Interfibrillar dysplastic fibrils, "Luse bodies", and intracellular collagen were found in rheumatoid tissues. The diameters of collagen fibrils were significantly reduced compared with the control group (p0.01). The duration of the disease usually correlate…
Stimulation of peroxisomal palmitoyl-CoA oxidase activity by ciprofibrate in hepatic cell lines: comparative studies in Fao, MH1C1 and HepG2 cells.
1993
The response of two rat cell lines, Fao and MH1C1, and one human cell line, HepG2, to the peroxisome proliferator ciprofibrate, was studied. Using a fluorometric assay for palmitoyl-CoA oxidase, the dose- and time-dependent increase of this enzymatic activity was determined. From the lowest concentration (100 microM) stimulation is evident in the two rat cell lines. In the Fao line, the activity was stimulated reaching a seven-fold increase over the control level at 250 microM after 72 h of treatment. In the MH1C1 line, the maximum stimulation, four- to five-fold, was obtained at 250 and 500 microM after 72 h. In the HepG2 cell line, activity increased two-fold at 250 microM after 72 h reac…

Some Questions of Heinrich on Ultrapowers of Locally Convex Spaces
1993
In this note we treat some open problems of Heinrich on ultrapowers of locally convex spaces. In section 1 we investigate the localization of bounded sets in the full ultrapower of a locally convex space, in particular the coincidence of the full and the bounded ultrapower, mainly concentrating in the case of (DF)-spaces. In section 2 we provide a partial answer to a question of Heinrich on commutativity of strict inductive limits and ultrapowers. In section 3 we analyze the relation between some natural candidates for the notion of superreflexivity in the setting of Frechet spaces. We give an example of a Frechet-Schwartz space which is not the projective limit of a sequence of superreflex…

Paternity testing of endangered species of birds by DNA fingerprinting with non-radioactive labelled oligonucleotide probes
1993
In the last years, DNA fingerprinting became the most powerful tool for identification and paternity testing in man. The success of this method encouraged the German Federal Ministry of Environment, Natural Protection and Reactor Safety to apply DNA fingerprinting in the field of protection of endangered species of birds, such as birds of prey or parrots. In the last three years, we received more than 400 blood and tissue samples of 23 species of birds of prey or parrots, most of them obtained by confiscation, to establish paternity and legal breeding success. We used digoxigenated oligonucleotide probes, mainly (GGAT)4 and (GACA)4 for hybridization. In most cases of confiscated families of…
Operative Thorakoskopie beim Pneumothorax
1993
Zur operativen Therapie des rezidivierenden Pneumothorax mit Pleurektomie und Zystenresektion war bisher eine Thorakotomie notig. Der Thorax als praformierte Hohle bietet aber optimale Voraussetzungen fur einen thoraskopischen Eingriff. Die Abtragung von bullosen Lungenveranderungen erfolgt mit einem Klammergerat, die partielle Pleurektomie mit Praparationshaken und monopolarem Strom. Die Verminderung des Operationstraumas fuhrt zu einer besseren postoperativen Befindlichkeit der Patienten.

La aplicación del análisis conversacional a textos planificados: la Historia de la Conquista de L.J.Peguero
1993
El presente trabajo ha sido concebido desde la adopción de dos premisas básicas. En primer lugar, la necesidad de ampliar los estudios diacrónicos al análisis de varios estadios sincrónicos pertenecientes a épocas distintas, tal y como sugieren (Malmberg, 1967; Alvar,1975; Lapesa, l989). En segundo lugar, la posibilidad de trasladar esa vertiente histórica a una disciplina como el análisis conversacional, con el convencimiento de que si el modelo explicativo es adecuado, resultará válido también en otro tipo de datos. Esto significa que nuestro intento persigue en realidad un enriquecimiento doble, en la teoría y en el tratamiento del corpus: la historia de la lengua puede utilizar las apor…
La teoría del conocimiento en el "Tractatus"

La influencia de Wittgenstein en el pensamiento del siglo XX está fuera de toda duda. La radicalidad de sus planteamientos y el nivel fundamental en que se sitúa constituyen una buena guía para plantear qué sea la Teoría del Conocimiento.
Selective ortho-metallation reaction of the phosphine P(o-ClC6H4)Ph2. Synthesis and crystal structure of [Rh2(μ-O2CCH3)3(μ-(ClC6H3)PPh2(OH2)2]·CHCl3
1993
Abstract From the reaction of [Rh2(O2CCH3)4(MeOH)2] in hot acetic acid with P(o-ClC6H4)Ph2, two monometallated compounds [Rh2(O2CCH3)3(C6H4)P(o-ClC6H4)Ph(HO2CCH3)2] (1), already described, and [Rh2(O2CCH3)3{(ClC6H3)PPh2}(OH2)2] have been isolated. The new compound has been characterized by an X-ray study. It crystallizes in the triclinic space group P1. It contains three acetate groups bridging a Rh24+ unit that has a Rh-Rh bond distance of 2.426(1) A; the fourth bridging ligand is derived from one P(o-ClC6H4)Ph2 metallated in the halogenated ring. The two water molecules occupy the axial coordination sites.
