A prototype continuous wave MRI system operating at 7T has been used successfully to study a variety of heterogeneous materials exhibiting T2 relaxation values ranging from 10 micros to 50 ms. Two-dimensional images of a poly(methly methacrylate) (PMMA) resolution phantom (T2=38 micros) exhibited a spatial resolution of approximately 1mm at a magnetic field gradient strength of 200 mT/m. The technique was used to study the hydration, drying, and subsequent water penetration properties of cement samples made from ordinary Portland cement, and revealed inhomogeneities arising from the cure conditions. Sandstone samples from an oil reservoir in the North Sea were also studied; structure within these materials, arising from the sedimentary bed layering in the reservoir, was found to have an effect on their water transport properties. A section from a confectionery bar (T2* approximately 50-60 ms) was also imaged, and its internal structure could be clearly discerned.
OBJECTIVE: To describe the meal patterns and food use on weekdays among 10- to 11-year-old Finnish children and to analyse these in relation to family's socio-economic status and the child's behaviour. DESIGN: Cross-sectional study on a cohort of 404 children aged 10-11 years in the rural town of Ylivieska, mid-western Finland. METHODS: A food-frequency questionnaire including questions on meal patterns and food use and the Child Behaviour Checklist (CBCL) completed by the parents and the child together. RESULTS: Practically all children (99%) ate breakfast regularly, 94% had a daily school lunch and 80% had dinner at home daily. Vegetables were consumed daily at home by 26% and fruits or berries by 21%, while 46% of the children had salad daily at school. Twenty-four per cent ate sweets daily or nearly so on weekdays. The children from families of high socio-economic status ate vegetables more often, and fewer of them used butter or high-fat milk. The children with no regular family dinner ate sweets and fast foods more often, and had higher total CBCL problem scores than those with a regular family dinner. CONCLUSION: Skipping meals appears not to be common among Finnish children aged 10-11 years, but a considerable proportion consume sweets frequently and vegetables infrequently. High family socio-economic status and a tendency to eat together are associated with healthy food choices among schoolchildren.
