    Notes: Abstract The catalytic behaviour of Zn/Cr mixed oxides with different compositions was investigated as a function of the bulk and surface properties. It was observed that non-stoichiometric spinel-type phases were stable also in the reaction conditions, in which zinc-surface enrichment did not occur. The maximum productivity in methanol was observed for monophasic non-stoichiometric spinel-type samples with a Zn/Cr ratio near to one, whereas the samples richest in zinc, for which a side phase, ZnO also was detected, showed a strong decrease in activity. The catalytic data support the hypothesis that non-stoichiometric spinel is the active phase for the synthesis of methanol on coprecipitated Zn-Cr catalysts.

    Notes: Abstract Traditional O.R. systems are compared with problem solving in Artificial Intelligence via Expert Systems. The discussion centers on explicit knowledge representation. The general aspects are illustrated by two planning systems: · LESP 2: A learning system for inspection plan generation · IDA: A system for finding functions and solutions in construction

    Notes: Summary Polybia sericea (Olivier) (Hymenoptera: Vespidae) foragers were trained to visit experimental foraging plots and tests were conducted to determine the role of visual, olfactory, and chemotactile cues in prey location. Foragers approached prey from downwind and hovered downwind of visual and olfactory stimuli. Olfactory cues were more likely to elicit landing than were visual cues. Biting of potential prey was most consistently elicited by a combination of visual, tactile, and chemotactile cues. Foragers encountering large prey carried a piece back to the nest and returned for prey remains. These returning foragers used visual cues to direct intensive aerial search; olfactory prey cues elicited landing.

    Description / Table of Contents: Summary A precondition for satisfactory (long-lasting) prosthetic results is a good occlusion. This can sometimes only be achieved with the aid of orthodontics. This article concludes that orthodontics can be carried out in patients with reduced periodontal support provided, thorough periodontal treatment is carried out initially and treatment goals and biomechanics are carefully considered.
    Abstract: Résumé Pour que de soins prothétiques soient durables, il est essentiel de veiller à une bonne occlusion. Ce qui n'est souvent possible qu'en ayant recours à l'orthodontie. Il a été démontré qu'avec un traitement parodontal précis au départ, la délimitation exacte de l'objet des soins une bonne connaissance de la biomécanique, l'orthodontie s'avérait possible et recommandable même chez les patients présentant des troubles parodontaux.
    Notes: Zusammenfassung Eine Grundvoraussetzung für eine dauerhafte prothetische Versorgung ist eine gute Okklusion. Das kann old nur mit Hilfe der Orthodontie erreicht werden. Es wird gezeigt, daß mit exakter initialer Parodontalbehandlung, genauer Absteckung der Behandlungsziele und der Kenntnis moderner Biomechanik Orthodontis auch beim parodontal reduzierten Patienten möglich und empfehlenswert ist.

    Description / Table of Contents: Summary With cerebral-palsied patients modified activators are successfully used to treat oral sensorimotor disorders like defective speech articulation, mastication and swallowing habits and to reduce or stop constant drooling and pulling reflex grimaces. The appliances now being used have been developed during the last ten years. A detailed description regarding construction, handling and modifications is given.
    Abstract: Résumé On a utilisé avec succès des activateurs modifiés pour le traitement des patients ayant une paralysie cérébrale. Ces appareils diminuent le dérèglement sensori-moteur dans la région orale du patient, comme le manque de netteté du langage, la perte constante de la salive, les difficultés de manger et de boire et de faire de mimiques. Ces activateurs modifiés sont le résultat de 10 ans d'étude et on décrit leur construction et leur manipulation.
    Notes: Zusammenfassung Bei Patienten mit zerebralen Bewegungsstörungen bewähren sich zur Therapie sensomotorischer Störungen im Gesichts-, Mund- und Rachenbereich modifizierte Aktivatoren. Damit gelingt die Besserung der Sprachundeutlichkeit, des reflektorischen Grimassierens, des unkontrollierten Speichelverlustes und der behinderten Nahrungsaufnahme. Die verwendeten Apparate sind das Ergebnis einer zehnjährigen Entwicklung und werden mit ihren bewährten Modifikationen und hinsichtlich ihrer Handhabung beschrieben.

    Description / Table of Contents: Summary Sensory and motor disturbances centered around the facial, oral and pharyngeal area constitute the most severe handicaps in the cerebral palsied population. A short survey of the currently available therapeutic approaches is given. In more than 100 patients during the last ten years we used in addition individually modified orthodontic devices and witnessed many unexpectedly good results. Close cooperation with habilitation and rehabilitation specialists (dentists, orthodontists, developmental neurologists, speech therapists, physiotherapists) who have sufficient insight into general and local postural interactions, is mandatory. Thus the devices are always modified according to the actual sensory and motor situation and also to the immediate needs of functional training and developmental steps in the individual patient.
    Abstract: Résumé Les handicaps les plus sévères chez des patients infirmes moteurs cérébraux sont constitués par des troubles moteurs et sensitifs au niveau de la face, de la bouche et du pharynx. On va donc donner un court aperçu des possibilités thérapeutiques disponibles pour traiter ces troubles. Chez plus de 100 patients au cours de ces dix dernières années, nous avons utilisé des appareillages d'orthopédie dento-faciale modifiés de façon individuelle et avons constaté beaucoup de bons résultats inattendus. Il est absolument nécessaire de créer une collaboration étroite entre les spécialistes des diverses réhabilitations (médecinsdentistes, orthodontistes, neurologues, logopédistes, physiothérapeutes), spécialistes possédant des connaissances pratiques étendues concernant les interactions générales et locales. De la sorte, on a modifié de manière permanente les appareils en fonction de la situation sensori-motrice actuelle et on les a adaptés aux besoins immédiats des patients dans leur entraînement fonctionnel et au cours des différentes étapes de leur développment.
    Notes: Zusammenfassung Sensomotorische Störungen im Gesichts-, Mund- und Rachenbereich erweisen sich als die schwersten Behinderungen bei zerebral bewegungsgestörten Patienten. Es wird ein kurzer Überblick über die verfügbaren therapeutischen Möglichkeiten bei diesen Störungen gegeben. Bei mehr als 100 Patienten verwendeten wir in den vergangenen zehn Jahren zusätzlich individuell modifizierte kieferorthopädische Geräte und stellten viele unerwartet gute Erfolge fest. Eine enge Zusammenarbeit mit Habilitations- und Rehabilitationsspezialisten (Zahnärzte, Kieferorthopäden, Entwicklungsneurologen, Logopäden, Physiotherapeuten) mit ausreichendem praktischen Wissen über allgemeine und lokale Wechselwirkungen bei der Haltungskontrolle ist unbedingt nötig. Auf diese Weise werden die Geräte entsprechend der aktuellen sensomotorischen Situation ständig modifiziert und den unmittelbaren Bedürfnissen für die funktionellen Übungen und nächsten Entwicklungsschritte des Patienten angepaßt.
