Abstract:
Provided is an oxidation reactor capable of oxidizing hydrocarbons with both reaction efficiency and energy efficiency. The oxidation reactor according to the present invention includes a liquid inlet channel, a gas inlet channel, a gas-liquid mixing unit, and a flow reactor. Through the liquid inlet channel, a liquid containing a reaction substrate hydrocarbon is introduced. Through the gas inlet channel, a gas containing oxygen and ozone is introduced. The gas-liquid mixing unit mixes the liquid introduced from the liquid inlet channel with the gas introduced from the gas inlet channel. In the flow reactor, an oxidation catalyst is immobilized or packed. The gas-liquid mixing unit houses, in its channel, a mobile particle which is capable of rotating and/or moving to mix the liquid with the gas to thereby form a gas-liquid slug flow. The gas-liquid slug flow is introduced into the flow reactor.

Abstract:
The present invention is a sensor for detecting a microorganism, which is provided with a detection unit (17) equipped with a detection electrode (11) and a polymer layer (14), wherein the polymer layer (14) is arranged on the detection electrode and is provided with a template having a three-dimensional structure complementary to a three-dimensional structure of a microorganism (13) to be detected. The sensor detects a microorganism on the basis of the captured state of the microorganism onto the template (15). The polymer layer (14) is formed by a manufacturing method including a polymerization step (St1) of polymerizing a monomer in the presence of the microorganism (13) to be detected to form a polymer layer (14) having the microorganism (13) incorporated therein on the detection electrode, and a disruption step (St2) of bringing at least a part of the microorganism (13) incorporated in the polymer layer (14) into contact with a solution containing a lytic enzyme to disrupt the microorganism.
Abstract:
The purpose of the present invention is to provide a novel method for producing cereulide and a derivative thereof; an intermediate for cereulide; and a novel cereulide derivative. A novel didepsipeptide, a novel tetradepsipeptide, a novel octadepsipeptide and a novel dodecadepsipeptide are prepared. A linear precursor of cereulide or a derivative thereof, which is composed of any one of the novel depsipeptides, is cyclized by forming an intramolecular amide bond.
Abstract:
An optical fiber (1) includes (i) an inner core (111) whose refractive index distribution has an α profile, (ii) an outer core (112) which surrounds the inner core (111), and (iii) a clad (12) which surrounds the outer core (112). In the optical fiber (1), Rd is set to not less than 0.15, where Rd is a ratio of a refractive index difference between the outer core (112) and the clad (12) to a refractive index difference between a center part of the inner core (111) and the clad (12).

Abstract:
A method for creating an image database comprising an extraction step of extracting reference feature vectors from a reference image which should be compared with a retrieval query image for object recognition, the reference feature vectors corresponding to local features at different positions of the reference image and representing the position and characteristics of each of the local features as a vector position, vector length, and a vector direction, a clustering step of creating a plurality of clusters consisting of different reference feature vectors in such a manner that each reference vector belongs to any of the plurality of clusters, a selection step of selecting the representative vector of the clusters from among the reference feature vectors of each of the clusters, and a step of associating the representative vector with the reference image and registering the representative vector associated therewith in the image database for the object recognition, wherein, in the clustering step, each of the clusters is created in such a manner that reference feature vectors at a near vector position belong to the same cluster, and in the selection step, reference feature vectors with long vector length are given priority to select the representative vector, and wherein the retrieval query image and the reference image are compared with each other by generating at least one query feature vector from the retrieval query image, and applying local search between the query feature vector and the representative vector, each of the steps being executed by computers.
