Abstract: A process and a system for producing a melt including urea, biuret, and a minor amount of N-containing compounds, the process including pumping a urea melt to one or more reactor vessels each having a headspace at a top part thereof and a bottom part, subjecting the urea melt in the one or more reactor vessels to a heating process with a temperature of between 150° C. to 180° C., during the heating process also subjecting the melt present in the reactor vessel(s) to a circulation process in and out of the one or more reactor vessels via a circulation loop arranged externally from each of the reactor vessels, wherein during formation of the melt, gaseous by-products are produced which are evacuated out of the respective reactor vessel via the top part thereof, and removing the melt out of the one or more reactor vessels via the bottom part thereof.

Abstract: A first neural network (NN) model may generate labels for training a second NN model. The second NN model may represent instances of a NN model operating on multiple different devices (e.g., decentralized user and/or edge devices). The system may include using a “teacher” model to process data received by one or more of the devices to generate a labeled dataset. The system may use the labeled dataset and a “student” model to calculate gradient data for updating the student model. The student model may be the same or similar to NN model instances operating on the devices. The system may validate the updated student model to determine, for example, whether it exhibits improved performance when processing the newly received data and/or historical data. The system may distribute the validated update to the devices.

Abstract: The present disclosure relates to the use of a mixture of urea, biuret and N-containing by-products of the biuret production out of urea, as a NPN-source in a ruminant feed supplement composition (i) to reduce methane emission produced by ruminant animals, (ii) to decrease the acetate to propionate ratio produced by rumen microbes in a ruminant, (iii) to improve the EMPS, (iv) to increase the DM and OM digestibility, and/or (v) to improve the dry matter intake (DMI) of ruminant animal. The present disclosure further relates to a ruminant feed supplement composition comprising urea, biuret and N-containing by-products of the biuret production out of urea, as well as to methods of feeding a ruminant with a feed comprising said ruminant feed supplement composition.

Abstract: A ruminant feed supplement composition including urea, biuret and one or more nitrate compounds. The present disclosure further relates to the use of such a ruminant feed supplement composition as a NPN-source to improve nitrogen nutrition and to reduce methane emissions and further to improve the efficiency of microbial protein synthesis (EMPS) by rumen microbes in a ruminant animal; and/or to decreasing the acetate to propionate ratio produced by rumen microbes in a ruminant animal; and/or to increasing the (in vitro) dry matter (DM) and organic matter (OM) digestibility; and/or to improve the average daily gain (ADG) of a ruminant animal; and/or to improve the feed efficiency of a ruminant animal.

Abstract: An electrical system for generating arbitrary voltage waveform includes a power supply unit for providing a supply voltage to the electrical system. One or more charge pumps are in electrical communication with the power supply unit. Each charge pump generates a voltage. The electrical system also includes a plurality of switches, a first switch among the plurality of switches coupled between a ground and an output terminal, other switches among the plurality of switches coupled between the one or more charge pumps and the output terminal. A control circuit is in electrical communication with the power supply unit, the plurality of switches and the one or more charge pumps, and is operable to control the voltage generated by the each charge pump and the plurality of switches. Voltages from the one or more charge pumps additively result in a variable output voltage that generates an arbitrary voltage waveform.

Abstract: In a process of manufacturing screen material a metal matrix is subjected to an electrolytic metal deposition by using an electrolytic bath containing a brightener, the liquid of the bath being forced to flow through apertures in the cathode toward the anode. The metal deposits grow substantially perpendicular to the lands of the matrix and so form a screen having apertures of approximately the same size as the apertures of the original matrix. The screen can be removed from the matrix by previously coating the latter with a separating agent such as beeswax.An installation for performing the process of the invention comprises a perforated cathode as matrix being fixed to cathode fixing means, a perforated anode being fixed to anode fixing means and a pump for providing a forced flow of liquid through the apertures of the cathode toward the anode.

Abstract: Metal screen comprising ribs and apertures and process of electrolytically forming a metal screen by forming in a first electrolytic bath a screen skeleton upon a matrix provided with a separating agent, such as beeswax, stripping the formed screen skeleton from the matrix and subjecting the screen skeleton to an electrolysis in a second electrolytic bath in order to deposit metal onto said skeleton. The second electrolytic bath contains an organic compound having at least one unsaturated bond not belonging to a ##STR1## group. Preferred organic compounds are a butyne diol or an ethylene cyanohydrin. The screen is preferably a cylindrical screen.
