Scanning Electron

In comparison with the developers of other forms of instrumentation, scanning electron microscope manufacturers are among the most conservative of people. New concepts usually must wait many years before being exploited commercially. The field emission gun, developed by Albert Crewe and his coworkers in 1968 is only now becoming widely available in commercial instruments, while the innovative lens designs of Mulvey are still waiting to be commercially exploited. The associated electronics is still in general based on operating procedures which have changed little since the original microscopes of Oatley and his co-workers.The current interest in low-voltage scanning electron microscopy will, if sub-nanometer resolution is to be obtained in a useable instrument, lead to fundamental changes in the design of the electron optics. Perhaps this is an opportune time to consider other fundamental changes in scanning electron microscopy instrumentation.

The Impact

Intake of vitamins A, C, and E was evaluated and age and time trends were assessed on the basis of 3-day weighed dietary records (n = 5121) of 2- to 18-year old boys (n = 417) and girls (n = 425) enrolled in the DONALD Study (Dortmund Nutritional and Anthropometric Longitudinally Designed Study) 1986–2001. Intake of vitamin A remains stable over time, intake of vitamin C increases linearly, and intake of vitamin E follows a nonlinear trend. Age trends of vitamins A and C (per MJ) were nonlinear with a minimum at the beginning adolescence, while intake of vitamin E (per MJ) increased linearly. Girls had higher nutrient densities but lower intakes expressed as percent of reference values. Fortified food in total had a higher impact on time trends of nutrient intake than other single food groups defined here. Our results point to the impact of the food industry on long-term nutrient intake, but also underline the necessity of nutrition education even in young age groups to improve vitamin intake.
