Abstract: An hydroponic/aeroponic agricultural unit that involves sealing the plants in a highly water saturated environment which more closely recreates the feel of natural rainwater. Also, this invention features the ability of quickly changing from a small housing into a larger housing by varying the diameter of a drum so that a small drum can act as a nursery for seedlings. Once the seedlings have turned into plants, the drum is made larger. The plurality of planks making up the drum can be positioned close to the lamp when they are small and farther away when larger. A simple yet reliable system allows for the rotation of the drum.

Abstract: A method for decimating seismic traces in an acquisition of 3D data, recording, for each trace, the corresponding source-receiver couple coordinates (Sa1, Ra1), positioning on a decimation grid (D), divided into cells, the source-receiver couple that corresponds to each trace, regrouping all source-receiver couples into iso-path trace collections, where each collection regroups the traces whose seismic paths are identical or similar, organizing the traces in each iso-path collection, and selecting the first trace in each iso-path collection.
