Fit-for-purpose is a phrase familiar to all users of analytical data, who need to be assured that data provided by laboratories is both appropriate and of the required quality. Quality in the Food Analysis Laboratory surveys the procedures that a food analysis laboratory must consider to meet such requirements. The need to introduce quality assurance, the different quality models that are available and the legislative requirements are considered. Specific aspects of laboratory practice and particular areas of accreditation which may cause problems for analytical laboratories are also...

'Of realty the rarest-veined unraveler', John Duns Scotus was one of the profoundest metaphysicians who ever lived. In this volume, the world's foremost Scotus scholars collaborate to present the latest research on his work. In ethics, the focus is on practical wisdom, on beauty as an ethical concept, and on the independence of the virtues; in metaphysics, on modality, individuation, and being. Textbook accounts notwithstanding, Scotus's theory of logical possibilities implies no existence or actuality for possible beings though being and thinking presuppose the domain of possibility; potency...

The English Franciscan philosopher and theologian, Adam of Wodeham (d. 1358), was a disciple and friend of William of Ockham; he was also a student of Walther Chatton. Nevertheless, he was an independent thinker who did not hesitate to criticize his former teachers - Ockham sporadically and benevolently, Chatton, frequently and aggressively. Since W odeham developed his own doctrinal position by a thorough critical examination of current opinions, the first part of this introduc- tion briefly outlines the positions of the chief figures in the English controversy over indivisibles. The second...

Examines attitudes and uses of metaphor in Elizabethan poetry, concentrating on "The Faerie Queene". This work shows that the Elizabethan trust in the veracity of metaphor offers a possible explanation for the structure of certain literary forms of the period.

A NATO Advanced Study Institute on "Active Defence Mechanisms in Plants" was held at Cape Sounion, Greece, 21 April - 3 May 1981. It succeeded a similar Institute held at Porte Conte, Sardinia in 1975 on "Specificity in Plant Diseases. " What are active defence mechanisms in the context of plant disease in which a plant, the host, may be damaged by a pathogen? Defence mechanisms comprise properties of the host that decrease this damage. The mechanisms are passive when they are independent of the pathogen. They are active when they follow changes in the host caused by the pathogen. Thus for a...

A NATO Advanced Study Institute on "Phytotoxins in Plant Diseases" was held in Pugnochiuso (Italy) in June 1970. It was concerned mainly with the chemistry and mode of action of substances toxic to higher plants which are produced by pathogenic bacteria and fungi. The role of such substances in specificity was consider- ed but largely in relation to host-specific toxins. In 1973, in light of the success of the 1970 Institute, we decided to plan for another in 1975 and after discussion with col- leagues during the Second International Congress of Plant Pathology, we selected "Specificity in...
