In the very early design phases of Concorde Powerplant it was realized that the high airflows passing through the engine bay would pose significant problems in terms of the precautions necessary to withstand and extinguish fires within the powerplant. A better understanding of the conditions existing in the bay during fires would produce a rational approach to the problem for both the designer and the certifying authority. In order to obtain extensive coverage of all flight conditions it was necessary to depart from current practice and to construct a simulation of the engine and its environment thereby allowing a large number of tests to be carried out. Using this rig it has been possible, not only to prove the means of detection and extinguishing throughout the flight plan, but to obtain a considerable amount of generalized data for use in component design specifications.

Fundamental Polyhedron

Considering the future development and general solution of the problem under consideration and also the high precision attainable by astronomical observations, the following procedure may be the most rational approach:1. On the main tectonic plates of the Earth’s crust, powerful movable radio telescopes should be mounted at the same points where standard optical instruments are installed. There should be two stations separated by a distance of about 6 to 8000 kilometers on each plate. Thus, we obtain a fundamental polyhedron embracing the whole Earth with about 10 to 12 apexes, and with its sides represented by VLBI.

INTRODUCTION: Schistosomiasis has been described as “one of the most devastating diseases of mankind, second only to malaria in its deleterious effects on the social and economic development of populations in many warm areas of the world.” The disease is worldwide and is probably spreading faster and becoming more intense than the overall research efforts designed to provide the basis for countering it. Moreover, there are indications that the development of water resources and the demands for increasing cultivation and food in developing countries may prevent adequate control of the disease and thus the number of infections are increasing.Our knowledge of the basic biology of the parasites causing the disease is far from adequate. Such knowledge is essential if we are to develop a rational approach to the effective control of human schistosomiasis. The miracidium is the first infective stage in the complex life cycle of schistosomes. The future of the entire life cycle depends on the capacity and ability of this organism to locate and enter a suitable snail host for further development, Little is known about the nervous system of the miracidium of Schistosoma mansoni and of other trematodes. Studies indicate that miracidia contain a well developed and complex nervous system that may aid the larvae in locating and entering a susceptible snail host (Wilson, 1970; Brooker, 1972; Chernin, 1974; Pan, 1980; Mehlhorn, 1988; and Jones, 1987-1988).

Opinion Article

Abstract The purpose of this opinion article is to review the impact of the principles and technology of speech science on clinical practice in the area of craniofacial disorders. Current practice relative to (a) speech aerodynamic assessment, (b) computer-assisted single-word speech intelligibility testing, and (c) behavioral management of hypernasal resonance are reviewed. Future directions and/or refinement of each area are also identified. It is suggested that both challenging and rewarding times are in store for clinical researchers in craniofacial disorders.

Solution Focused Therapy

The concept of client-centered therapy (Rogers, 1951) has influenced many professions to refocus their treatment of clients from assessment outcomes to the person who uses the information from this assessment. The term adopted for use in the professions of Communication Sciences and Disorders and encouraged by The American Speech-Language-Hearing Association (ASHA) is patient-centered care, with the goal of helping professions, like audiology, focus more centrally on the patient. The purpose of this paper is to examine some of the principles used in a patient-centered therapy approach first described by de Shazer (1985) named Solution-Focused Therapy and how these principles might apply to the practice of audiology. The basic assumption behind this model is that people are the agents of change and the professional is there to help guide and enable clients to make the change the client wants to make. This model then is focused on solutions, not on the problems. It is postulated that by using the assumptions in this model audiologists will be more effective in a shorter time than current practice may allow.
