Abstract: A method includes storing, in computer memory, a tessellation comprising a plurality of tiles corresponding to a plurality of geographical regions. The plurality of tiles are stored with travel times in a plurality of transportation modalities across a plurality of edges of the plurality of tiles. The method also includes storing, in the computer memory, associations between a plurality of points of interest and corresponding tiles of the plurality of tiles based on locations of the plurality of points of interests relative to the plurality of geographic regions, determining, by one or more processors, a first set of the plurality of tiles reachable from a first tile of the plurality of tiles in up to a first total travel time based on the travel times across the plurality of edges, and identifying, by the one or more processors, a first set of the plurality of points of interest associated with the first set of the plurality of tiles.

Abstract: The present invention relates to a process for the partial and differential extraction that leads to obtaining extracts with appreciable amounts of antioxidants from fruits of palm trees of the genus Euterpe. The process comprises the steps of collecting the fruit, solid-liquid extraction (pulping 1) of the antioxidant compounds, softening and/or maceration of pulp and solid-liquid extraction (pulping 2 and/or 3) to obtain a standardized juice comprising both hydrophilic and lipophilic antioxidants, and an oily fraction. The process of the present invention also extends to a partial purification of the crude aqueous extract produced by the technique of adsorption on macroporous resins, resulting in higher purity extract of antioxidants.

Abstract: The filtering structure (20) for a vent device for a liquid container comprises at least two rigid outer elements permeable to gases and to liquids and having confronting parallel bearing surfaces, and an intermediate element 14 permeable to gases and impermeable to liquid is intended to be maintained in a static position between the bearing surfaces of the rigid elements.
