  • Patent number: 10704055
    Abstract: The proposed innovation relates to the biotechnological improvement of plant species of commercial interest. More specifically, the present invention relates to the production of transgenic plants biotechnological with greater tolerance to water deficit and salt stress by means of the expression of a new gene of coffee (of the Coffea Arabica species), belonging to the HD-Zip family, and characterized by a homeodomain associated with a leucine zipper. The expression of this transcriptional factor is induced in leaves and roots of coffee plants subjected to various water deficit conditions (both moderate and severe); transgenic plants that over-express this gene inhibiting greater tolerance both to differ drought intensities and to high salt concentrations.

  • Patent number: 10687068
    Abstract: A method for compressing light field data using variable block-size four-dimensional transform and bit-plane hexadeca-tree decomposition, the method including: partitioning a four-dimensional pixel data of a light field into four-dimensional blocks of independent fixed size; partitioning the four-dimensional blocks in a set of four-dimensional non-overlapping sub-blocks of different sizes according to a rate-distortion criterion; independently transforming the four-dimensional sub-blocks generated in the previous operation, using a four-dimensional transform; quantizing by bit-planes the sub-blocks transformed by the four-dimensional transform according to Rate-Distortion optimized hexadeca-tree structure; and encoding the four-dimensional quantized data generated through an arithmetic encoder to produce a compressed representation of the light field.

  • Publication number: 20150240173
    Abstract: The invention relates to the preparation of carboxylic acid esters compounds, biodiesel (B) from microalgae, for use as a biofuel for compression type ignition. The objective is achieved through a hydroesterification process of a microalgae biomass (MU) comprising a hydrolysis stage and the esterification stage by means of heterogeneous catalysis. The wet microalgae biomass (MU) is the result of a process of cultivation concentration and is hydrolyzed directly in a hydrolysis column (20). Fatty acids (C), water (A) and raw glycerin (G) are obtained following the hydrolysis. The fatty acids (C) are esterified by reactive distillation in the presence of an impregnated heterogeneous catalyst (I).
