Diferencias individuales y riesgo en la conducción. Historia de un reto todavía no resuelto
1992
Se puede hablar con total propiedad de una tradición española en el estudio y la aplicación de los conocimientos psicológicos al fenómeno del tráfico, que se inicia en los años 20, si bien los primeros trabajos sistemáticos se realizaron fuera de nuestras fronteras. Se trata probablemente de la única competencia profesional de intervención psicológica regulada legalmente y mantenida a lo largo de toda la historia contemporánea española. El hilo conductor lo ha constituido el examen psicotécnico de selección de conductores -a profesionales primero, y a todos los conductores después- que en su estructura revela la evolución de la psicología. Con todo, paulatinamente se ha ido produciendo una …

Conservative Surgery of Renal Tumors: Operative Technique, Complications, Results, DNA Cytometry
1992
Until now radical nephrectomy has been regarded as the standard therapy for nonmetastasized renal cell carcinoma. This operation has been accepted because of the theoretical advantage of a more complete resection. A parenchyma-sparing operation was only performed in patients in whom radical nephrectomy would result in renal failure requiring hemodialysis (imperative indication), such as patients with single kidney, bilateral tumors, dysfunctional contralateral kidney, or chronic renal failure. However, the widely used partial nephrectomy in these instances may in certain cases result in insufficient residual renal parenchyma. Simple enucleation of the tumor with a small surrounding margin o…
Quantitative DNA measurements in malignant and benign lesions of the upper aerodigestive tract.
1992
Thirty-six patients underwent biopsy of clinically suspicious lesions of the mucosa of the upper aerodigestive tract. The biopsy material was evaluated histologically and cytologic smears out of the same lesion underwent quantitative DNA analysis using a numerical index derived from the single cell DNA content. In 30 patients, histologically diagnosed squamous cell cancer was confirmed by DNA analysis with the malignancy grade correlating with the morphologic differentiation of the tumor. Six lesions were histologically benign: i.e. dysplasia (n = 3), hyperplasia (n = 2) and chronic inflammation (n = 1). DNA analysis confirmed the benign nature in 4 cases, but in 2 cases of dysplasia, a dia…
Properties of Hadronic Z-decays and Test of QCD Generators
1992
Distributions are presented of event shape variables, jet roduction rates and charged particle momenta obtained from 53 000 hadronic Z decays. They are compared to the predictions of the QCD + hadronization models JETSET, ARIADNE and HERWIG, and are used to optimize several model parameters. The JETSET and ARIADNE coherent parton shower (PS) models with running alpha(s) and string fragmentation yield the best description of the data. The HERWIG parton shower model with cluster fragmentation fits the data less well. The data are in better agreement with JETSET PS than with JETSET O(alpha(s)2) matrix elements (ME) even when the renormalization scale is optimized.

Regionale Analysen der Krebsinzidenz bei kleinen Fallzahlen
1992
Seit 1980 dokumentiert das Mainzer Kinderkrebsregister bundesweit die malignen Erkrankungen bei Kindern unter 15 Jahren. Zu den registrierten Daten gehort neben Angaben wie Name, Alter, Diagnose und Erkrankungsdatum die Gemeinde, in der das erkrankte Kind bei Diagnosestellung wohnte. Diese Angabe dient als Grundlage zur kartographischen Aufbereitung der regionalen Inzidenzen, die eine wichtige Aufgabe von Krebsregistern darstellt (1).
Zu den Ursachen der unterschiedlichen pH-Empfindlichkeit vonGammarus pulex L., G.fossarum KOCH (Amphipoda) undAselus aquaticus L. (Isopoda)
1992
By means of ion chromatography the extensive and significantly higher loss of ions of G. pulex and G. fossarum in acid water (pH 3.0) as compared to neutral water is proved. While cations are being accumulated in the water, some ions (Na+, Cl−) leave the hemolymph in important percentage, others increase highly after being set free from the cells (K+ and Ca2+). The loss of cations with Asellus aquaticus in acid water (pH 3) is clearly lower than with Gammarus, and it is not significantly higher than when the animals are put into neutral water.
Clinical Use of Oxygen Stores: Pre-oxygenation and Apneic Oxygenation
1992
During states of respiratory arrest the human oxygen stores may be used therapeutically, regardless of the origin, i.e. either prior to the routinely induced apnea for endotracheal intubation or as an emergency measure in any other case of apnea. The present considerations focus on the clinical use of the oxygen stores available, applying.
Evidence for a geranyl-diphosphate synthase located within the plastids of Vitis vinifera L. cultivated in vitro
1992
Intact plastids from cell suspensions of Vitis vinifera L. cv. Muscat de Frontignan, free of detectable contamination by other particles as judged by the distribution of organelle-specific marker enzymes and by electron microscopy, exhibit geranyl-diphosphate synthase activity (EC 2.5.1.1). This synthase activity remains stable after tryptic digestion of unlysed organelles and is enhanced by plastid disruption. We conclude that the enzyme is located within the organelle. The possibility of an isopentenyl diphosphate/dimethylallyl diphosphate translocating system which would play a major role in the regulation of monoterpene metabolism is discussed.

The influence of the raw material and production method on the morphology, microstructure, chemical and phase composition of tetrabasic lead sulfate …
1992
Abstract Tetrabasic lead sulfate (4BS) produced by two different methods (solution and paste) and from two different raw materials (tetragonal PbO and leady oxide) were charaterized by different analytical techniques. The techniques applied were wet-chemical methods, scanning electron microscopy, transmission electron microscopy and X-ray powder diffraction. The preparation method was observed to be the most decisive factor influencing the structure and the morphology of the 4BS pastes in this study.
Using Cox's proportional hazards model for prognostication in carcinoma of the upper aero-digestive tract.
1992
One of the major short comings of the traditional TNM system is its limited potential for prognostication. With the development of multifactorial analysis techniques, such as Cox's proportional hazards model, it has become possible to simultaneously evaluate a large number of prognostic variables. Cox's model allows both the identification of prognostically relevant variables and the quantification of their prognostic influence. These characteristics make it a helpful tool for analysis as well as for prognostication. The goal of the present study was to develop a prognostic index for patients with carcinoma of the upper aero-digestive tract which makes use of all prognostically relevant var…
Roolileikkiin siirtyminen leikin kehitysvaiheena : piagetilainen näkökulma
1992
The general purpose of this study was to develop the research methodology and theory of play. More precisely, the aim was to describe and analyse the stage of transition to role play as a developmental psychological and pedagogical phenomenon. The study is part of a larger research project and part of a developmental program focusing on enhancing the quality of education in day care centers. Four tasks were set for the study. The first task was to perform a· theoretical analysis of the development of play and the transition to role play on the basis of Piaget's theory of play. The second task was to define and revise this analysis according to the results of piagetian observation studies of…
«Enfre la vinya e·l fenollar»? La composició del «Llibre d'Amic e Amat» i l'experiència mística de Ramon Llull
1992
The essay's main purpose is to eradicate the topic that the Blaquerna is in fact Llull’s autobiography and that the LAA reflects in a direct way R. Llull's mystical experience. While the LAA fits perfectly the general structure of the Blaquerna and could very well nave originally been conceived as a part of this novel, the evidence so far available seems to indicate that the LAA never existed as an independent text.
Automation of the determination of hydrogen peroxide, dichromate, formaldehyde and bicarbonate in milk by flow injection analysis
1992
Automatic flow injection methods for the determination of hydrogen peroxide, dichromate, formaldehyde and bicarbonate in dairy products are proposed. They are based on reaction with vanadium pentoxide, diphenyl-carbazide, fuchsine-sulphur dioxide and alizarin, respectively. Sample pre-treatment (paper and membrane filtration, dialysis) is widely discussed for on-line incorporation. The usefulness of these methods was tested by applying them to different commercial samples, satisfactory results being obtained in all instances.

Mercado de trabajo juvenil y políticas de empleo
1992
El paro juvenil es una de las características distintivas de la nueva situación que conocen muchas economías industrializadas desde 1973. En este articulo se reflexiona sobre las causas y consecuencias de la peor situación que soporta el colectivo juvenil en el mercado de trabajo. Las causas ha que buscarlar más en las condiciones generales de la economía del mercado de trabajo que en las características individuales de los jóvenes. Las consecuencias repercuten sobre el concepto mismo de juventud y sobre los procesos de inserción de las nuevas generaciones en la sociedad. Finalmente, se reflexiona también sobre la filosofía que sustenta la política de empleo juvenil. L'atur juvenil és una d…
Relationships between psychomotor retardation and EEG power spectrum in major depression.
1992
In 63 depressed patients, the associations between severity of depression, psychomotor retardation, assessed by the Bech-Rafaelsen Melancholia Scale, and EEG spectral analysis were examined. Slow EEG activity (theta 2/alpha 1 bands) was positively and fast activity (alpha 3/beta bands) negatively correlated with the observed retardation. Out of the four retardation subitems (motor, verbal, intellectual and emotional), motor retardation was closest correlated with slow EEG activity.

(2'-5')Oligoadenylate and intracellular immunity against retrovirus infection.
1992
1. 1. The double-stranded RNA-dependent 2′,5′-oligoadenylate (2–5A) synthetase/ribonuclease L (RNase L) system plays an essential role in the establishment of the antiviral state of a cell exposed to virus infection. 2. 2. Until recently, the application of 2–5A derivatives to reinforce this system seemed to be limited mainly due to the low specificity of RNase L for viral RNA. 3. 3. Two new strategies have been developed which yield a selective antiviral effect of 2–5As at least against human immunodeficiency virus-1 (HIV-1) infection: (i) an “intracellular immunization” appproach using 2-5A synthetase cDNA linked to HIV trans -acting response element (TAR) and (ii) inhibition of retrovira…

Studies on Italian reservoirs
1992
The main morphometric and water quality characteristics of the 221 Italian reservoirs covering an area of at least 0.2 km2 is given. Most of the reservoirs are used for drinking water purposes, especially on the islands of Sicily and Sardinia, where the more important cases of eutrophication have been found. These situations are examined in greater detail, with regard to algal population dynamics, the phosphorus budget and the comparison between theoretical and experimental nutrients loads. -from Authors
