The primary objective of this study was to establish a temporal profile of pyrethroid exposure in a cohort of elementary school age children living in an urban/suburban community, using urinary pyrethroid metabolites as exposure biomarkers.
The primary objective of this study was to investigate the effects of an afterschool science and engineering program, Studio STEM, on upper-elementary and middle grades students' beliefs about science, and their motivation and engagement in the program.
The primary objective of the longitudinal study by Lu et al. (2006a) was determination of "overall pesticide exposure in a group of elementary school-age children".
The primary objective of this study is to use a novel study design to determine the contribution of daily dietary pesticide intake to the overall pesticide exposure in a group of elementary school-age children using a longitudinal approach.
While constraint-based methods usually provide solutions that optimize a certain objective, elementary flux modes (EFMs) capture the whole spectrum of metabolic steady states of a given network.
Allan Ludman, chairman of the college's School of Earth and Environmental Sciences and a member of a steering committee for the new elementary school, said one objective was to create a curriculum in which reading, social studies and the humanities were blended with math and science lessons.
Among students included in the second objective, 102 elementary and 272 secondary school students shifted their travel mode from passive in the morning to active in the afternoon.
For the second objective, among 1,086 and 2,479 elementary and secondary school students from the first objective, 741 (61.6%) and 1,960 (77.2%) who did not walk/bike to school in the morning were included.
An "elementary landscape" exists if the objective function f is an eigenfunction of the Laplacian of the graph induced by the neighborhood operator; this allows various statistics about the neighborhood to be computed in closed form.
To handle multiple control objectives simultaneously, a library of elementary behaviors is defined; then, multiple elementary behaviors are combined, in a given priority order, into tasks (compound behaviors); to this aim the Null-Space-based Behavioral (NSB) approach has been adopted.
