Abstract: Surfactin-based lipopeptides for mRNA delivery are made by a method including providing OleSurf lipids to form an organic phase, mixing a mRNA in 100 mM citrate buffer at pH 4 to form an aqueous phase, mixing one part of the organic phase with three parts of the aqueous phase to obtain mRNA loaded lipid nanoparticles, purifying the mRNA loaded lipid nanoparticle platform using dialysis, and purifying the mRNA loaded lipid nanoparticle platform using centrifugal filtration. The OleSurf lipids are made by modifying surfactin with oleylamine. The resulting nanoparticles may be useful as mRNA delivery vehicles.

Abstract: An electronic device that detects and analyzes the energy emitted by brains of individuals. This device measures and analyzes the energy emitted from the brain activity of, for example, students, enabling the classification of students with learning difficulties based on the quantity of emitted energy. Leveraging established measuring devices, supported by computer programs akin to those utilized in electrocardiography, enables the prediction of both the quantity and speed of brain energy based on the magnetic field's intensity. By comparing the intensity of the magnetic field resulting from electrochemical energy in the brain with standard measurements for the general populace, learning difficulties can be diagnosed effectively.

Abstract: A dual feed slot-based circularly polarized wideband ultra high frequency (UHF) antenna for a cubic shaped satellite (Cube-Sat) is described. The UHF antenna includes a circuit board, a metallic layer, a hexagonal meandered slot, a capacitor, a first feed horn, and a second feed horn. The circuit board has a front side and a back side separated by a dielectric material. The metallic layer covers the back side of the circuit board. The hexagonal meandered slot symmetrically includes six legs of equal length and six vertexes. The capacitor is switchably connected to the metallic layer. The first feed horn is connected by a first feed line to a first edge of the front side of the circuit board. The second feed horn is connected by a second feed line to a second edge of the front side of the circuit board.

Abstract: There is provided a system and method for collecting water droplets from an airflow of a cooling tower (8) through condensation of water vapour using an electrostatic separator (20), wherein the electrostatic separator is a single unit electrostatic separator (20) or a multi-unit electrostatic separator. The method for water particles collection from the exhaust airflow of a cooling tower primarily comprises condensing water vapour into large water droplets. It is experimentally proved that electrostatic separation solves the problem of visible plume pollution, and blow down decreased since collected water flows back to the circulating water. Additionally, electrostatic separation results in small pressure drop of the cooling tower (8).

Abstract: A method for producing a core-shell capsule for delivering a therapeutic agent is provided. The method includes printing a composite material via a nozzle on a substrate while moving the nozzle in a pre-designed pattern to create the shell of a hollow capsule. The shell defines a cavity within the hollow capsule, and the shell has an opening at an apex of an outer surface of the shell. The method includes introducing a composition, in liquid form, containing the therapeutic agent at a temperature of at least 45° C. into the cavity of the hollow capsule via the opening of the shell, and naturally cooling the composition inside the shell to solidify the composition and adhere the composition to an inner surface of the shell thereby forming a core of the core-shell capsule.

Abstract: The present disclosure relates to pipeline corrosion inhibitor optimization and control. In an example, a failure probability representative of a likelihood of a pipeline corrosion failure and a consequence level representative of a consequence from the pipeline corrosion failure can be computed. A risk matrix can be generated and used to identify an inhibitor concentration based on the failure probability and consequence. A dosage of a corrosion inhibitor for mitigating corrosion of a pipeline can be computed based on the inhibitor concentration. In some examples, the dosage of the corrosion inhibitor can be adjusted based on a modification factor computed at least based on a corrosion rate measured for the pipeline.

Abstract: A pre-set inhibiting extrusion limiter has a segmented anti-extrusion ring with a plurality of anti-extrusion ring segments supported by a stepped cone frustum. Each ring segment is retained in a run-in condition by a compression spring retained by a retainer ring held in a retainer ring groove in the respective anti-extrusion ring segments. A push ring moves the respective anti-extrusion ring segments from the run-in condition to a packer-set condition in which the anti-extrusion ring segments abut a cone frustum step of the stepped cone frustum.

Abstract: A fingerprint scanner for capturing fingerprints of infant children is described. The fingerprint scanner includes a transparent tube configured for an infant child hand and an array of camera sensors spaced apart on the transparent tube so that each camera sensor captures an overlapping part of an image captured by its neighboring camera sensor. The array of camera sensors is arranged below a surface, along a periphery of a circumference and substantially along a length of the transparent tube up to a processor compartment. The fingerprint scanner also includes a processing circuitry configured to: simultaneously receive multiple images from the array of camera sensors, and process the multiple images including merging the multiple images to remove overlapping portions and recover a single image of the infant child's fingertips and palm.
