OBJECTIVE To determine if the treatment of stunted children offered at a specialized center influences their cognitive performance. METHODS Two groups of children from vulnerable families were selected, one consisting of stunted children being treated at the Nutrition Education and Recovery Center (CREN), and the other group of eutrophic children from a local, public day care center. At CREN,...

Attine ants engage in a quadripartite symbiosis with fungi they cultivate for food, specialized garden parasites, and parasite-inhibiting bacteria. Molecular phylogenetic evidence supports an ancient host-pathogen association between the ant-cultivar mutualism and the garden parasite. Here we show that ants rear the antibiotic-producing bacteria in elaborate cuticular crypts, supported by uniqu...

this study describes the length-weight and length-length relationships for 28 populations of garra ruffa in different basins of iran, including tigris, karkheh, karun, persis and hormuz. the length-weight relationships from most localities are reported here for the first time. for most populations the b value was not significantly different from 3, indicating an isometric growth, in a few, it w...

Food caching has been linked to better performance on spatial memory tasks and enlarged hippocampal volume in both birds and mammals. Within food-caching birds, it has also been predicted that species less reliant on stored food should have inferior spatial memory and a smaller hippocampus compared to species that depend heavily on food caches. Several comparisons suggest that North American co...

THE methods hitherto employed in the study of the gross metabolism of insects have been based mainly on the changes in their content of physiologically important substances during development, and on the ability of the organism to grow on selected diets of known composition. There is a third method, extensively employed by mammalian physiologists, namely analysis of excreta; this, as Uvarov (19...

Translating Dialects in Search: Mapping between Specialized Languages of Discourse and Documentary Languages by Vivien Petras Doctor of Philosophy in Information Management and Systems University of California, Berkeley Professor Michael K. Buckland, Chair The biggest problem in searching an information system is to find the appropriate search terms that not only represent the searcher’s inform...
