Universidad EAFIT is a private Colombian university located in Medellín. Originally founded by a group of the city's business leaders to establish an academic institution focusing on business administration, presently the university offers programs in other cities of Colombia , countries and has established international partnerships not only with academic institutions abroad, but also with multinationals, such as Hewlett-Packard. The university was key in bringing Hewlett-Packard's operations to Medellín, and functioned as its local headquarters before HP moved to its own building in the north side of the city.The university currently offers 21 undergraduate programs and more than 100 graduate programs in the areas of Management, Engineering, Law, Finance and Economics, and Science and Humanities. Universidad EAFIT was approved by the Colombian Ministry of Education on May 6, 1971. It has three branches in Bogotá, Pereira and Rionegro. Wikipedia.

The present invention refers to a process designed to increase the production of plant growth-promoting microorganisms of the Bacillus genus, using a culture medium poor in nutrients and with specific environmental conditions, allowing to obtain a greater amount of biomass and/or spores, which can be used to prepare solid or liquid compositions to be applied to plants, aiming to promote their growth and/or counteract the effect of phytopathogenic agents.


Patent
Cementos Argos S.A. and EAFIT University | Date: 2015-09-30

This invention relates to a device with function for measuring volumetric changes in a substance. In particular, the device with function for measuring volumetric changes in a substance comprises a sensor that detects the amount of light intensity produced by a light source aligned with said sensor when passing through a column of two liquids which are immiscible among each other contained in a transparent tube, wherein the sensor and the aligned light source are mounted on an arm that travels on a vertically arranged rail, wherein the arm is attached to a strap which acts by means of a first and a second pulley causing the movement of said arm, wherein the movement of said pulleys comes from a motor and a gearbox and the entire mobility system is mounted on a frame. The device further comprises data acquisition means which record the change of light intensity and control the arm movement.

The invention relates to a method for compacting particulate material by compression. The invention especially relates to a method for compacting particulate material, including a compression compacting method for preparing units of particulate materials. Said particulate materials to be treated can comprise, but are not limited to, cement, calcium, gypsum, mortar, combinations thereof and the like, in order to improve the packaging, storage, transport, presentation, dosage and preparation thereof, thereby benefiting the manufacturer, the distributor and the consumer. The invention reveals the possibility of applying different pressures for the compression and shaping of the compacted product into different geometrical shapes, for the packaging, storage, transport, presentation, dosage, preparation and use thereof, from the opening of the packaging to the final application.

The present invention discloses a device for evaluating the technical condition of the tread of moving railway vehicles, especially for automated inspection of the loss of roundness of each wheel of circulating railway vehicles, in which a point of measrement is used which generates a signal proportional to rail deformation when a wheel arch passes over said point. Then the comparator system compares the measured signal with a wheel pattern without any roundness defects, which is then transmitted over a data network that associates the wheel identification information, with the wheel defect data generated by the comparator system each time the wheel passes over said measurement area.


The present invention relates to a system and method for the automated inspection of geometric parameters of railway wheels rolling on a track by artificial vision techniques. The present invention uses a structured light source (10) that illuminates a line of light (12) upon a fraction of the surface of revolution (3) of a wheel (1), a CCD camera (20), which captures an image (21) of the illuminated area, and a data processing system that records, digitalizes, geometrically corrects and reconstructs information of the surface of revolution (3) that is not recorded in the image (21), in order to obtain a numeric description of the complete transverse section of the wheel (1) represented by a reconstructed profilogram (500) for calculating the geometric parameters of the wheel (1).


The present invention refers to a process for increasing the production of biomass and metabolites of microorganisms of Bacillus sp. species. Obtained metabolites are lipopeptide compounds of the fengycin, surfactin, and iturin families, which exhibit antimicrobial activity. The invention further includes biocidal compositions comprising Bacillus subtilis EA-CB 0015, Bacillus amyloliquefaciens EA-CB0959, and/or metabolites thereof, either alone or together with other biocidal agents, and the use of these compositions for the treatment of diseases caused by various phytopathogenic agents, including Mycosphaerella fijiensis, in a variety of crops.
