Abstract: A communication route setting device 100 of the present invention includes an optical signal acquisition unit 121 that acquires an optical signal on a transmission path in a network in which optical communication devices are connected to each other via an optical transmission path, a condition determination unit 122 that determines a physical condition of at least one object of the optical transmission path and the optical communication devices on the basis of the optical signal, and a route setting unit 123 that sets a communication route for transmitting the optical signal on the network on the basis of the determined physical condition.

Abstract: In order to attain an object of providing a technique to, upon detection of an abnormality in a welded part, provide notification of a factor of the detected abnormality, an abnormality diagnosis apparatus includes: an acquisition means (21) for acquiring time series data containing at least one of an electric current value and a voltage value at first welding; an abnormality determination means (22) for determining, with use of an abnormality determination model and based on the time series data acquired by the acquisition means, whether or not there is an abnormality in a welded part at the first welding; and an output means (23) for, if the abnormality determination means has determined that there is an abnormality, outputting the determination result and at least one of a factor of the abnormality and a remedial method for solving the abnormality.

Abstract: Provided is a novel peptide having ACE inhibitory activity. Specifically, provided is a tripeptide consisting of Leu-Arg-Ala.

Abstract: A system stores clustering information obtained by clustering multiple sets of viewpoints relative to teeth of a three-dimensional model of a patient and projection images of a head including the teeth from the respective viewpoints. At the time of a surgery, the system creates comparative images from a photographed image taken by a monocular camera and searches for any viewpoint having a projection image similar to the comparative image sequentially from a first hierarchy to a final hierarchy in the clustering information. The system sets a representative viewpoint based on the viewpoint of the final hierarchy, restores position and posture of the teeth of the patient relative to the monocular camera as position and posture of the teeth of the three-dimensional model relative to the representative viewpoint, and generates and outputs a navigation image based on position and posture of surgical information relative to the teeth after the restoration.

Abstract: In cultivating a microorganism having nitrile hydratase production ability, by allowing at least one of a ketose, such as fructose, and a sugar alcohol, such as mannitol, to be present, growth inhibition by cobalt ion is prevented, thereby achieving cultivation at a high concentration and with a high activity.

Abstract: A body cavity-observing apparatus includes an endoscope with an imaging optical system on the front edge thereof, a prism movably mounted on the forefront of the imaging optical system, and an actuator to drive the prism on a given command signal. A different endoscope image is obtained by moving the prism, and thus, a wide range endoscope image can be easily obtained.

Abstract: A biological process for predominantly producing an optically active .alpha.-hydroxycarboxylic acid having a phenyl group directly from a racemic .alpha.-hydroxynitrile or a mixture of an aldehyde corresponding to the nitrile and prussic acid as a substrate is disclosed, comprising reacting a microorganism belonging to the genus Rhodococcus, Alcaligenes, Brevibacterium or Pseudomonas with the substrate in a neutral to basic aqueous medium. A desired optically active .alpha.-hydroxycarboxylic acid having a phenyl group can be obtained quantitatively at a high optical purity.

Abstract: A process for preparing an optically active lactic acid comprising subjecting DL-lactonitrile or acetaldehyde and prussic acid to the action of a microorganism belonging to the genus Enterobacter, Arthrobacter, Caseobacter, Brevibacterium, Aureobacterium, Escherichia, Micrococcus, Streptomyces, Flavobacterium, Aeromonas, Nocardia, Mycoplana, Cellulomonas, Erwinia, Candida, Pseudomonas, Rhodococcus, Bacillus, Alcaligenes, Corynebacterium, Microbacterium or Obsumbacterium, or treated microbial cells thereof, which the microorganism is capable of stereospecifically hydrolyzing a nitrile in a polar solvent. D-Lactic acid or L-lactic acid can be produced directly in a predominant proportion from the starting materials.
