Trace Metals In Sea Water

DISPONIBILIDADE IMEDIATA

 In recent years, rapid scientific advances have been shattering classical concepts of oceanic trace metals concentrations. Most of the data gathered before the mid-1970s have had to be discarded. Possible associations of organic and inorganic ligands with the metals were throwing views of metal speciation into great uncertainty. Biological effects of metals need to be re-examined after recent revelations of unsuspected metal contaminations in methodology. The investigations appear chaotic, yet exciting. It implies that a new order is going to replace the past. Now, an opportunity opens its door to a brave new world for the young generation of scientists to put metal chemistries in the oceans into perspectiveo This N. AoToO. International Conference on "Trace Metals in Sea Water" hoped to catalyze this exciting process of unifying various aspects of trace metals in sea water in future years o The Conference, in the form of an Advanced Research Institute supported by the Scientific Affairs Division of NoAoT. O. supple- mented by further assistance of the UoS. Office of Naval "Research, was held at the "Ettore Majorana" Center for Scientific Culture in the medieval town of Erice on the island of Sicily, Italy from March 30 to April 3, 1981. It was the first organized gathering of international scientists in this specialized field. Seventy scientists with various expertise in different aspects of the subject were present: including those from NoAoT. Oo countries (Canada, France, F. R. Germany, Greece, Iceland, Italy, U. K.

Applied General Systems Research - Recent Developments And Trends

118,59€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 This volume consists of a selection of papers presented at the International Conference on Applied General Systems Research: Recent Developments and Trends which was held on the campus of the State University of New York at Binghamton in August 15-19, 1977, under the sponsorship of the Special Panel on Systems Science of the NATO Scientific Affairs Division. General systems research is a fairly new field which has been developing in the course of the last two or three decades. In my op~n10n, it can be best described as a movement which involves the study of all structural and context independent aspects of problem solving. As such, it is cross-disciplinary in nature and, in this sense, it might seem similar to mathematics. There is a consid- erable difference, however, between the two. While pure mathe- matics is basically oriented to the development of various axiomatic theories, regardless of whether or not they have any real world meaning, applied mathematics explores the applicability of some of these theories as potentially useful methodological tools in various problem areas. General systems research, in contrast with applied mathematics, is problem oriented rather than tool oriented. As such, it tries to develop genuine methods for solving systems problems, i. e. , structural type and context in- dependent problems. The term "genuine method" is used here to refer to a method which adjusts to the problem rather than re- quiring that the problem be adjusted to make the method applicable.

Dynamic Processes In The Chemistry Of The Upper Ocean

de J.D. Burton, P.G. Brewer e R. Chesselet

59,61€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 The. Advanced Research Inst i tute (ARI) on Dynamic Processes in the Chemistry of the Upper OCean had its origins in discussions by the NATO Special Programme Panel on Marine Sciences during 1978 when a wide range of topics for future ARIs was being considered. What was then envisaged was a workshop on chemical aspects of the oceanic mixed layer, at which consider ation would be given to the inputs, cycling and removal of material, and the problems involved in the quantitative assessment of fluxes. It was realised that any attempt to model chemical processes would need the active collaboration of workers from other fields, especially physical oceano graphers concerned with air-sea interaction and turbulence, and biological oceano~raphers with expertise in primary productivity and the cycling of particulate and dissolved organic material. As plans for the ARI developed further a somewhat different emphasis emerged, focused on the question as to how chemists should set about observing an environment as variable and dynamic as the upper ocean and selecting the appropriate scales for the framework of measurements to study a particular process, especially in the light of current knowledge of physical processes of transport and mixing. It was plain that the capabil ity of physical oceanographic methods to resolve differences on small spatial and temporal scales is considerably ahead of the capabilities of biologists and chemists who rely upon discrete sampling and complex lab oratory manipulations in order to obtain most of their data.

Recent Advances In The Psychology Of Language - Formal And Experimental Approaches

59,61€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 The Stirling Psychology of Language Conference was held in the University of Stirling, 21-26 June 1976. 250 people attended the conference and 70 papers were presented. The two volumes of Pro ceedings present a selection of papers from the conference reflect ing as far as possible the range of topics that were discussed. Volume 1 is concerned exclusively with language acquisition. In recent years the ''centre of gravity'' of acquisition research has shifted from syntactic and phonological description to the amor phous domains of semantics and pragmatics. This shift is reflected in the two large sections (II and III) devoted to these aspects of language development. In addition the volume contains three smaller sections dealing with general problems of acquisition theory, syntax and the development of comprehension, and applied developmental psycholinguistics. Volume 2 contains a substantial section of papers which stress the formal aspects of psycholinguistics: these include papers in which artificial intelligence figures prominently, papers which apply re cent developments in syntax and semantics to psycholinguistic prob lems, and papers that are broadly critical of the use psychologists have made of linguistic theories. Volume 2 also contains a section dealing with the experimental study of sentence comprehension and production, and there is a final section concerned with phonology and its development.

Environmental Assessment Of Socioeconomic Systems

59,61€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Neglect of the relation between the socio-economic system and its natural environment has had detrimental consequences in the past, for example - the pollution of the natural environment (water, air and soil) by producing, using and consuming the products of our industrialized economy, - the forseeable exhaustion of natural resources by continuing the increase of industrial production. Most of the recent activities, both in research and in adminis tration, against these impacts have been technically oriented, with the aim of stimulating and introducing new technologies of produc tion and new products to diminish the environmental pollution. But these efforts, which are of course necessary, cannot be successful in approaching the aim - which should and must in the long-term view be defined as the development of society in balance with the natural environment. Therefore, in addition to an assess ment of technologies, emphasis should be put on an assessment of socio-economic systems. On di~~erent levels, individual and social preferences determine quantities and qualities of production and consumption using economical values, e.g., market prices as regula tors. Following this argumentation, an environment assessment of activities against pollution has especially to consider the social response to environmental impacts. Of course, this topic must be a subject of interdisciplinary research. The challenge concerned in this context is to increase the knowledge of the relationship between social, economic and tech nical subsets.

Advanced Research Institutes are sponsored by the NATO Science Committee for the purposes of bringing together senior scientists to seek consensus on an assessment of the present state of knowl edge on a specific topic and to make recommendations for future research directions. Meetings are structured to encourage inten sive group discussion. Invitees are carefully selected so that the group as a whole will contain the experience and expertise neces sary to make the conclusions valid and significant. A final report is published presenting the various viewpoints and conclusions. The NATO Systems Science Panel noted that the systems approach is increasingly being applied to energy policy analysis and plan ning in both public and private sectors of national economies. Consequently, it seemed appropriate at this time to bring together experts to review and evaluate recent experience, in order to iden tify strengths and weaknesses in current prac tice, and to make recommendations for research directions.
