Previous studies suggest the importance of medial temporal lobe, areas of parietal cortex, and retrosplenial cortex in human spatial navigation, though the exact role of these structures in representing the relations of elements within a spatial layout ("allocentric" representation) remains unresolved. Hippocampal involvement, in particular, during memory processing is affected by whether a pre...

Many organisations are using the Web for electronic commerce or purely for the collection and dissemination of information based on forms and tables. For many of these organisations a bespoke Web design with specialised Java Script is what they want. However, for organisations not wishing to make this investment, a flexible system based on a standard XML DTD could fit the bill. Fully functional...

We use the simulation model ofCbalfallt and Gallant (IUS5) to investigate the fit of a Fourier flexible form to a cost function when interest is t.o estimate elasticities of substitution. The data is subject to errors in variables and the estimation method is seemingly unrelated regressions. \IVe use two approximating Fourier functional forms * Hesearch supported by C:-IPq ** Banco do Brasil, C...

Carotenoids are isoprenoids that extensively dispersed in foods have always been part of the human diet.Certain carotenoids can be transformed into retinoids with vitamin A activity, which is needed for humans. Additionally, they far more flexible, since may found not just as sources A, and also natural colors, antioxidants, health-promoting substances. Functional provide health advantages addi...
