Abstract: Monomeric VHH domain derived from anti-VP6 camelid antibodies, dimeric domain, immunization method, rotavirus detection method, vaccine composition, prevention and treatment methods for rotavirus infections, wherein said domain may be any of the amino acid sequences shown in SEQ ID No. 1, SEQ ID No. 2, SEQ ID No. 3 or SEQ ID No. 4, and wherein said domains bind to protein VP6 of Group A rotavirus.

Abstract: A load transfer device for seed and fertilizer distribution systems in seeders and fertilizers improving adaptation of seed distribution systems to the different ground irregularities, comprising a deformable parallelogram-shaped structure attached to such seeder and fertilizer machine tool-holder bar at one end and to the distribution system at the other end; a transfer rack that articulates in one of the parallelogram vertexes acting as a rocker arm connected at one end to the aforementioned parallelogram and at the other end to at least one spring through a lever arm; wherein such lever arm extends downwardly and divergently, generating a crossing angle between the parallelogram lower and upper sides, creating a torque that varies not only for the spring tension but also for the ratio of the lever arms effective lengths involved. The system is installed in seed and fertilizer distribution systems, to improve movement along the ground.

Abstract: Herbicide-resistant rice plants, isolated polynucleotides that encode herbicide resistant and wild-type acetohydroxyacid synthase large subunit 1 (AHASL1) polypeptides, and the amino acid sequences of these polypeptides, are described. Expression cassettes and transformation vectors comprising the polynucleotides of the invention, as well as plants and host cells transformed with the polynucleotides, are described. Methods of using the polynucleotides to enhance the resistance of plants to imidazolinone herbicides, and methods for controlling weeds in the vicinity of herbicide-resistant plants are also described.

Abstract: A drag-type cotton harvester operated by an independent driving unit, which comprises a stripper-type cotton picker platform having a series of fingers that are aligned parallel to the forward direction of the machine, wherein the front ends of the fingers are close to ground level and the back ends thereof are ramped in an upward direction; a cleaning apparatus that receives the picked cotton from the picker platform, which cleaning apparatus comprises a set of rotary dentate cylinders that engage the cotton and remove the heavy masses or impurities therefrom, while a rotary brush that is disposed tangential to the dentate cylinders disengages the clean cotton from the aforementioned fingers; and a trailer that receives the clean cotton from the cleaning apparatus, then stores it and transports it.

Abstract: A cylindrical fermentation tank having a plurality of inner guides defining pathways for vertical movement of at least one grid connected to a rod axially extending into the tank and vertically actuated by a pneumatic cylinder, wherein the grid has an outer diameter and the tank has an inner diameter, with the outer diameter of said grid being slightly smaller than the inner diameter of the fermentation tank. The upper grid comprises a tubular frame allowing the flow of heat/coolant liquid/gas.
