Use of any multiresidue method (MRM) is supported by available information about how potential residues behave through the steps of the method. To provide that support for PAM I MRMs, additional chemicals are continually tested through the method steps and the resulting data compiled in a single database. All PAM

A. Trichopoulou and A. Naska, University of Athens 2.1 Introduction Documenting and monitoring dietary patterns are priorities in nutritional epi￾demiology, in the planning of national food and nutrition policies and in the evaluation of nutrition education strategies. Early efforts in documenting dietary patterns were focused on identifying the specific nutrients that may be respon￾sible for effects on people’s health, but recently research has expanded towards studying patterns of food intake. Food data are often derived from:

Determining wastewater flowrates and constituent mass loadings is a fundamental step in initiating the conceptual process design of wastewater treatment facilities. Reliable data for existing and projected flowrates affect the hydraulic characteristics, sizing, and operational considerations of the treatment system components

Computer networks are geographically distributed collections of communication links and switching proces￾sors, the purpose of which is to transport data between computers, workstations, and terminals. In general the elements of a computer network must follow compatible rules of operation together to function effectively. These rules of operation are known as protocols
