The participation in interlaboratory studies and the use of Certified Reference Materials (CRMs) are widely recognised tools for the verification of the accuracy of analytical measurements and they form an integral part of quality control systems used by many laboratories, e.g. in accreditation schemes. As a response to the need to improve the quality of environmental analysis, the European Commission has been active in the past fifteen years, through BCR activity (now renamed Standards, Measurements and Testing Programme) in the organisation of series of interlaboratory studies involving...

Fungi growth in the storage of cereal grain has led to serious losses of grain quality and quantity each year the world over. These fungi and moulds are capable of producing mycotoxins which accumulate in grains. This book contains reviews from 21 experts on the relationship between mould growth in grain and its effects as well as the accumulation of mycotoxins. Discussed are properties of "storage fungi" such as the water and temperature relationship, taxonomy and nomenclature aspects etc. New methods of storage allow for early detection of these mould growths. Significant attention is paid...

This unique and comprehensive text considers all aspects of heat exchanger fouling from the basic science of how surfaces become fouled to very practical ways of mitigating the problem and from mathematical modelling of different fouling mechanisms to practical methods of heat exchanger cleaning. The problems that restrict the efficient operation of equipment are described and the costs, some of them hidden costs, that are associated with the fouling of heat exchangers are discussed. Some simple concepts and models of the fouling processes are presented as part of the introduction to the...

The Symposium on Magnetic Ultrathin Films, Multilayers and
Surfaces, hosted by the European Materials Research Society, was
held at the Palais de la Musique et des CongrE in
Strasbourg, France on June 4-7, 1996. Its central theme was the
relationship of magnetic properties and device performance to
structure at the nano and micrometer length scale. Research on
the magnetism of surfaces, ultrathin films and multilayers has
increased dramatically during recent years. This development was
triggered by the discovery of coupling between ferromagnetic
layers across...
