Abstract: A novel method for producing an olefinic resin porous material with no skin layer is provided. The method for producing an olefinic resin porous material disclosed herein includes the steps of preparing a single phase in which an olefinic resin, a hydrocarbon compound, and a polar compound are mixed one another, in a pressure-resistant container, introducing high pressure carbon dioxide into the pressure-resistant container, and releasing the pressure in the pressure-resistant container. The polar compound has a hydroxy group or a carbonyl group. Introducing the high pressure carbon dioxide is carried out such that the pressure in the pressure-resistant container reaches 6 MPa or higher.

Abstract: An information processing system includes a storage device that stores therein a trained model, and a processor. The trained model is trained to output a position and shape of an object in a training image based on training data. The training data is data in which the training image is provided with an annotation indicating the position and shape of the object. The training image is an image captured with an angle of view including the object whose position and shape are not clearly displayed in an image. The processor executes detection processing on a detection image to output detected information indicating the position and shape of the object. The processor then causes a display device to display the detected information superimposed on the detection image.

Abstract: An information processing system includes a processor that performs an object detection to detect an object from a detection target image. The processor divides the detection target image into a group of first grid cells. The object is positioned to overlap a group of second grid cells included in the group of the first grid cells. At this time, the processor generates a bounding box in a respective second grid cell included in the group of the second grid cells. The processor surrounds a portion of the object positioned in the respective second grid cell with the bounding box generated in the respective second grid cell and displays, on a display, a position and shape of the object by a collection of a plurality of bounding boxes superimposedly on the detection target image.

Abstract: A method for liquefying niobium and tantalum and a method for producing a niobium solution and a tantalum solution, which can liquefy niobium and tantalum or produce a niobium solution and a tantalum solution safely and efficiently from a smelting raw material containing niobium and tantalum. Ammonium hydrogen sulfate is mixed as a reaction agent into a powdered substance containing at least one element of niobium or tantalum, and the mixture is melted under predetermined conditions to form a molten substance. A suspension formed by dissolving the molten substance having been solidified in an aqueous solution is subjected to solid-liquid separation to recover a precipitate. The precipitate is composed of niobium and/or tantalum with few impurities, and the precipitate is dissolved in one type of acid solution selected from hydrochloric acid, sulfuric acid, or nitric acid, whereby 90% or more of niobium and/or tantalum can be leached out.

Abstract: A polymer solution is created by mixing an olefin-based resin and a solvent in a pressure vessel. A high-pressure fluid of carbon dioxide is created. Temperature of the high-pressure fluid is adjusted. A mixed fluid is created by mixing the high-pressure fluid of which the temperature is adjusted and the polymer solution in the pressure vessel. Cooling of the mixed fluid causes phase separation of the mixed fluid to occur. After phase separation, pressure in the pressure vessel is released, and the solvent and the carbon dioxide vaporize. The vaporizing of the solvent and the carbon dioxide creates a porous medium of olefin-based resin.
