Medikamente zur Behandlung extrapyramidalmotorischer Störungen
1996
Antiparkinsonmittel werden in diesem „Grundris“ aus 2 Grunden berucksichtigt: Sie haben einmal psychische Eigenwirkungen und werden zum anderen in Form von m-Cholinozeptorantagonisten in der psychiatrischen Pharmakotherapie als Adjuvanzien benotigt, wenn unter einer neuroleptischen Therapie extrapyramidalmotorische Nebenwirkungen (s. S. 192) auftreten.
Effects of Pulsed High-Frequency Electromagnetic Fields on Human Sleep
1996
In the present study we investigated the influence of pulsed high-frequency electromagnetic fields of digital mobile radio telephones on sleep in healthy humans. Besides a hypnotic effect with shortening of sleep onset latency, a REM suppressive effect with reduction of duration and percentage of REM sleep was found. Moreover, spectral analysis revealed qualitative alterations of the EEG signal during REM sleep with an increased spectral power density. Knowing the relevance of REM sleep for adequate information processing in the brain, especially concerning mnestic functions and learning processes, the results emphasize the necessity to carry out further investigations on the interaction of…

Land-Based Pollution in the Mediterranean Sea Area
1996
This paper deals with the political and legal regional approach adopted by the Mediterranean coastal States in order to prevent, abate, combat and eliminate to the fullest possible extent pollution of the Mediterranean Sea Area caused by discharges from rivers, coastal establishments or outfalls, or emanating from any other land-based sources and activities within their territories. I pay a special attention to the 1996 amendments to the Protocol for the Protection of the Mediterranean Sea against Pollution from Land-Based Sources (Athens, 17 May 1980).

VLBI Observations of FRI Radio Galaxies
1996
The Fanaroff-Riley type I radio galaxies (Fanaroff & Riley, 1974) presented in this paper belong to the complete sample of low-intermediate luminosity radio galaxies published in Giovannini, Feretti & Comoretto (1990). This sample includes radio galaxies with different morphologies on the arcsecond scale, such as compact sources, core-halos, FRIs and FRIIs.
Estimation of Number-Average Molecular Weights of Copolymers by Gel Permeation Chromatography−Light Scattering
1996
The true number-average molecular weight, Mn, of copolymers is obtained by GPC coupled with a light-scattering detector even if the composition and therefore the refractive index increment varies with elution volume, provided slices taken are monodisperse with respect to molecular weight and composition. In contrast, only an apparent weight-average molecular weight, can be obtained by the conventional GPC−light scattering combination, even for a perfect chromatographic resolution. The errors in Mn associated with nonhomogeneous slices are estimated. Experimental data with mixtures of linear polystyrene and poly(methyl methacrylate) confirm these estimations and indicate that the error in Mn…
Inner Edge Drag by an Asynchronous Primary and Accretion Disc Structure In Close Binaries
1996
In this work a 3-D ‘Smoothed Particle Hydrodynamics’ ([1]; [4]; [5]) accretion disc is simulated where particles at its inner edge are dragged by a fast spinning compact central star, as in the case of the intermediate polars. The angular velocity of the central star is twice the orbital angular velocity w 0. This drag can be attributed mainly to viscous interaction in the dense compact star atmosphere, although magnetic coupling may also play a role.

XRD Line Broadening Studies on Mullite
1996
An X-ray diffraction microstructural study on 110, 220, 001 and 111 peaks has been performed on mullite in the temperature range of primary mullite formation in order to monitor nucleation and growth process. Considering the crystallinity of the starting kaolinites, a greater disorder of the kaolinite has been found to enhance the mullite formation. Isothermal growth is related to a decrease in the Al 2 O 3 content of mullite.
Partial *-algebras of closable operators: A review
1996
This paper reviews the theory of partial *-algebras of closable operators in Hilbert space (partial O*-algebras), with some emphasis on partial GW*-algebras. First we discuss the general properties and the various types of partial *-algebras and partial O*-algebras. Then we summarize the representation theory of partial *-algebras, including a generalized Gel’fand-Naimark-Segal construction; the main tool here is the notion of positive sesquilinear form, that we study in some detail (extendability, normality, order structure, …). Finally we turn to automorphisms and derivations of partial O*-algebras, and their mutual relationship. The central theme here is to find conditions that guarante…
Demokratie und Gemeinschaft. Oder: wie kontrovers ist die Kommunitarismusdebatte?
1996
"Unter dem Etikett der 'Kommunitarismusdebatte' wird seit einigen Jahren der Umgang mit Differenz und die Integration unterschiedlicher Bevölkerungsgruppen in ein demokratisches politisches System kontrovers diskutiert. Der Streit zwischen 'Kommunitaristen' und 'Liberalen' entzündet sich üaber die Grundlagen der modernen Demokratie. Vereinfacht gründet sich für die Kommunitaristen Demokratie zuerst auf Gemeinschaft und für die Liberalen zuerst auf Gerechtigkeit. Die Kommunitarismusdebatte blieb trotz einer großen Zahl von Beiträgen auf die Analyse moderner westlicher Demokratien beschränkt und sie weist zudem ein 'soziologisches Defizit' auf. Auf diese Lücken zielt meine Fragestellung. Wie …
Les coûts de production de vins d'AOC en Bourgogne
1996
The characteristics of the production process of wine in Burgundy are the small size of the viticultural holdings and the fact that each vine-grower cultivates several patches in different villages, which permits them to produce wines belonging to one of the four hierarchical levels in the "guaranteed vintage" system (AOC). Such an organization incites to define the concept of "vintage portfolio" associated with each viticultural holding.The aim of our paper is to verify if the behaviour of the vine- growers leads them to have production costs (here the cost of grapes) that depend on the one hand on their vintage portfolio and on the other hand on their stategy. Concerning this last element…

Comparison of sampling methods for semipelagic animals in two deep basins of Lake Saimaa
1996
The efficiency of different methods for sampling semipelagic animals was compared in the deep basins of Lake Paasivesi and Lake Puruvesi of the complex Lake Saimaa, Finland, during 1990–92. Certain semipelagic animals, such as Mysis relicta, amphipods and larvae of Chaoborus flavicans, are important bioindicators of water and benthic quality. However, owing to their high mobility and vertical migrations they are difficult to sample quantitatively with traditional benthic methods.
Method Engineering: Current research directions and implications for future research
1996
In this study we investigate method engineering research by classifying studies into three contexts: technology, language and organization. Within each context we examine research bias, research outcomes and use of alternative research methods. This survey reveals the inherent bias of ME research towards tool and language development at the cost of empirical studies. We lack investigations of why organizations develop their own “variants” of system development methods, and how they manage their method engineering efforts. These observations lead us to suggest some directions for future research, which relate both to actual research questions and to the use of complementary research methods.

We give a nonimmersibility theorem of a compact manifold with nonnegative scalar curvature bounded from above into a geodesic ball of a simply connected space form.
Symmetry operators in computer vision
1996
Symmetry plays a remarkable role in perception problems. For example, peaks of brain activity are measured in correspondence with visual patterns showing symmetry. Relevance of symmetry in vision was already noted by Köler in 1929. Here, properties of a symmetry operator are reported and a new algorithm to measure local symmetries is proposed. Its performance is tested on segmentation of complex visual patterns and the classification of sparse images. Copyright © 1996 Elsevier Science Ltd.

Il linguaggio degli uccelli: Aristotele e lo specifico fonetico del linguaggio umano
1996
A partire da Pagliaro e Belardi, padri fondatori degli studi italiani di fonetica greca, prevale la convinzione che lo specifico del linguaggio umano non si trovi su base fonetica. Spcifico del linguaggio sarebbe 'non la fonicità nè l'articolazione ma la funzione simbolica. Attraverso l'analisi minuziosa delle opere di Aristotele, il contributo si propone di sfatare questo mito. L'analisi è condotta sul linguaggio degli uccelli, in confronto al linguaggio fonetico umano. Il risultato è che, per quanto gli uccelli siano capaci come gli uomini di produrre voce articolata (dialektos) è questo è importanti a livello di continuità fra le specie e come smentita dell'antropocentrismo, il linguaggi…
Modeling harmonic generation by a degenerate two-level atom
1996
An analytical theory of the generation of high-order harmonics of laser radiation has been developed on the basis of a two-level model atom with degenerate levels. Among other parameters, onset, width, and cutoff of the plateau in the harmonic spectrum are obtained in simple analytical forms that connect the basic problem parameters and permit a transparent interpretation of the mechanism underlying the spectrum formation for this specific case. Selected numerical calculations are reported to corroborate the analytical findings and to investigate other harmonic-spectrum features.
Consumer Satisfaction with Outpatient Mental Health Care: Impact of an Organizational Change in Mental Health Center Function from Hospital District …
1996
In Finland the administrative responsibility for outpatient psychiatric care has in part been reorganized from specialized psychiatric treatment organizations to health centers. This change has been encouraged by economic pressures, but data about its impact on the quality of treatment and patient satisfaction are limited. We carried out a follow-up study by using the UKU Consumer Satisfaction Rating Scale (UKU-CONSAT) and qualitative interviews to estimate consumer satisfaction with the psychiatric outpatient care just before and 1 year after such a change. The results suggest that dissatisfaction may emerge if too little attention is paid to the longevity of the treatment relationships an…
Solitons in Nonlinear Transmission Lines
1996
Although solitary waves and solitons were originally discovered in the context of water waves and lattice dynamics, consideration of these physical systems (which will be considered in Chaps.5 and 8) leads to calculations far too involved for pedagogical purposes. Thus, for an introduction to the soliton concept, we therefore consider simple wave propagation in electrical nonlinear transmission lines and electrical networks.
Reactions in Spain to the expulsion of the Jesuits from France
1996
Los sucesos que afectaron a los jesuitas en Portugal y Francia fueron seguidos con curiosidad e interés en los ambientes cultos españoles. A través de la correspondencia cruzada entre Gregorio Mayans y diversos personajes, entre los que se encontraban el obispo Asensio Sales, el bibliotecario real Martínez Pingarrón, y el jesuita P. Juan Bautista Gener, y otros, se analizan las actitudes de simpatía o antipatía que suscitaban las medidas antijesuíticas y la gestación de un ambiente proclive a la expulsión. Así mismo, se trata de la repercusión de la consulta del Consejo de Castilla sobre los jesuitas franceses exiliados en España, con referencia al eco que produjo en el Provincial de Aquita…

A lattice study of the form factors A(0) and A(3) in the decay (B)over-bar(0)->rho(+)l(-)(nu)over-bar(l)
1996
We report on a lattice calculation of the form factors A(0) and A(3) for the pseudoscalar to vector meson semileptonic decay (B) over bar(0) --> rho(+)l(-)(1). We find that resonant (or pole-type) contributions alone are unable to describe these two form factors simultaneously. For the quantity A(0)(q(2) = 0), which is important phenomenologically for the determination of \V-ub\, we extract a range of values, A(0)(q(2) = 0) = (0.16-0.35)(-6)(+9), where the range is due to systematic uncertainty and the quoted error is statistical. We have also determined A(2)(q(2) = 0) = 0.28(-6-5)(+9+4).
