[PROBLEM] In a gasification apparatus that heats and pressurizes a gasification feedstock to bring the gasification feedstock into a fluid in a supercritical state and performs decomposition-treatment on the gasification feedstock to obtain fuel gas, energy possessed by the treated fluid is effectively utilized, and production of tar is suppressed. [SOLUTION] A gasification apparatus configured to heat and pressurize a gasification feedstock to bring the gasification feedstock into a supercritical state, and perform decomposition-treatment on the gasification feedstock to obtain fuel gas, the gasification apparatus including: a heat exchanger 31 configured to introduce the gasification feedstock into a low-temperature-side flow channel 31a and introduce treated fluid in a supercritical state into a high-temperature-side flow channel 31b, so that heat exchange is performed between the gasification feedstock and the treated fluid; a gas-liquid separator 51 configured to extract, from the high-temperature-side flow channel 31b, the treated fluid that has been in a subcritical state due to heat exchange, perform gas-liquid separation on the treated fluid, and return a separated liquid to the high-temperature-side flow channel; and a turbine 61 that is powered by fuel gas separated by the gas-liquid separator.

A wind power generation device that generates power via bending deformation of a piezoelectric element as a result of vibrations of a power generation unit due to wind, wherein damage due to an increase in amplitude of the vibrations at the time of strong wind is suppressed and power is generated stably and efficiently by wind in a wide wind velocity range without impairing power generation performance in a normal wind velocity range. A lower end portion of a power generation unit (14) is connected to a slidably fitted portion (30) of a tension adjustment mechanism (20). When a strong wind blows, the slidably fitted portion (30) is moved by a lifting power F of a wing-like portion (38) from a first position (lifted end) to a second position (lowered end) as a result of an increase in wind velocity, resulting in greater tensile force of the power generation unit (14). Thus, the power generation unit (14) is suppressed from being damaged due to an excess amplitude of the vibrations of the power generation unit (14) when a strong wind blows. When a strong wind does not blow, the slidably fitted portion (30) is held at the first position, where the power generation unit (14) has small tensile force and can vibrate with a greater amplitude, enabling efficient generation of power by bending deformation of a piezoelectric film (46).

Disclosed is the provision of a method for assisting the detection of pancreatic cancer, the method assisting the detection of pancreatic cancer with high accuracy. In the method for assisting the detection of pancreatic cancer, the amounts of (1) miR-122-5p and (2) at least one miRNA selected from the group consisting of miR-16-5p, miR-19b-3p and miR-25-3p, all of which are contained in a test sample separated from a living body, are used as indicators. A larger amount of miR-122-5p and a smaller amount of at least one miRNA selected from the group consisting of miR-16-5p, miR-19b-3p and miR-25-3p than those in a healthy individual indicates that the living body is more likely to have developed pancreatic cancer.
