A better knowledge of the characteristics of muddy areas, in access fairways and port basins, and of the behaviour of ships during their crossing, presents the double interest of enhancing the navigation possibilities, through a more precise adjustment of the ship draught to the status of the bottoms, and permiting a more rational organization of the maintenance dredging campaigns. Considerable savings will be obtained through the development of such knowledges for harbours management. These improvements imply the use of measuring equipments which must be handy, sturdy, reliable and which give accurate measurements. The JTD3 gauge presented by the Radioisotopes Applications Service of the French Atomic Energy Commission is an important step in the development of such measuring equipments. It is now in running order, and commercially available, after thorough test campaigns, undertaken during many months in different french harbours. New developments are already engaged, namely through the design of a turbidity gauge able to make dynamic measurements.

Economic Considerations

The overall status of the fast breeder reactor (FBR) system is periodically reviewed in France. In 1983, a report was prepared on the status and prospects of the FBR system at the request of the then Minister of Industry. Five years later, Electricite de France (EdF) and the French Atomic Energy Commission (CEA) jointly updated this report. The FBR reactor system economic considerations mentioned here are taken from the work performed in 1987—88 for this updating. The position in 1983 is reviewed to highlight concrete developments. Developments that have occurred since then are presented, along with the prospects that today enable us to define better the technical and economic potential of the FBR system. In conclusion, the effects of these findings on desirable directions are discussed, in particular with regard to European FBR cooperation.

This paper concerns an analysis regarding the performance of X-ray equipment as well as the radiological safety in veterinary facilities. Data were collected from 380 X-ray veterinary facilities countrywide during the on-site regulatory inspections carried out by the Greek Atomic Energy Commission. The analysis of the results shows that the majority of the veterinary radiographic systems perform within the acceptable limits; moreover, the design and shielding of X-ray rooms as well as the applied procedures ensure a high level of radiological safety for the practitioners, operators and the members of the public. An issue that requires specific attention in the optimization process for the proper implementation of veterinary radiology practices in terms of radiological safety is the continuous training of the personnel. The above findings and the regulatory experience gained were valuable decision-making elements regarding the type of the regulatory control of veterinary radiology practices in the new radiation protection framework.

Belief Justification

Oxford Studies in Epistemology is a biennial publication offering a regular snapshot of state-of-the-art work in this important field. Under the guidance of a distinguished editorial board composed of leading epistemologists in North America, Europe and Australasia, it publishes exemplary papers in epistemology, broadly construed. Topics within its purview include: (a) traditional epistemological questions concerning the nature of belief, justification, and knowledge, the status of skepticism, the nature of the a priori, etc.; (b) new developments in epistemology, including movements such as naturalized epistemology, feminist epistemology, social epistemology, and virtue epistemology, and approaches such as contextualism; (c) foundational questions in decision-theory; (d) confirmation theory and other branches of philosophy of science that bear on traditional issues in epistemology; (e) topics in the philosophy of perception relevant to epistemology; (f) topics in cognitive science, computer science, developmental, cognitive, and social psychology that bear directly on traditional epistemological questions; and (g) work that examines connections between epistemology and other branches of philosophy, including work on testimony, the ethics of belief, etc. Topics addressed in volume 6 include the nature of perceptual justification, intentionality, modal knowledge, credences, epistemic supererogation, epistemic and rational norms, expressivism, skepticism, and pragmatic encroachment. The various writers make use of a variety of different tools and insights, including those of formal epistemology and decision theory, as well as traditional philosophical analysis and argumentation.
