A short food frequency questionnaire (FFQ) was assessed based on its ability to measure the consumption of cereal foods, fruit and vegetables among Chinese Singaporeans. Some 81 subjects were asked to fill out the 16-item questionnaire at the beginning and at the end of a six-week period during which the said subjects also presented three diet recalls. For the three food groups, the FFQ successfully predicted over 90% of the time those that had inadequate intake based on recall data. However, the FFQ cannot be used to replace the three-day recalls in assessing intake for individuals.

Abstract: Crystals of the new superconductor FeSe were investigated by X-ray absorption near edge structures spectroscopy (XANES) in the temperature range 300–77K. Crystals with Se content varying from x=1–0.8 were used. The Fe K-edge spectra show a structure distortion and increase in hole content as x decreases. The Fe K-edge spectra also show changes when the crystals are cooled to 100K which may be related to the orthorhombic distortion reported in these crystals. The data is examined in conjunction with XRD measurements on the crystals to seek a correlation. [Copyright &y& Elsevier]
