Abstract: The use of a metal complex containing a ruthenium ion or an osmium ion, and a tridentate aminodicarbene ligand, the tridentate aminodicarbene ligand having one secondary amino group and two specific heterocyclic carbene groups sandwiching the amino group, enables hydrogenation reduction of carbonyl compounds, such as ketones, carboxylic acid esters, lactones, carboxylic acid amides, and lactams, and imine compounds under relatively mild conditions to produce corresponding alcohols, amines, and the like in a high yield with high catalytic efficiency. The metal complex is obtained by a method comprising steps of reacting a specific metal compound with a specific aminodicarbene precursor and subsequently reacting a specific compound. Reduction of a carbonyl compound or an imine compound in the presence of this metal complex using a hydrogen donor makes it possible to reduce the carbonyl compound or imine compound by hydrogenation.

Abstract: The information providing system includes the communication unit, the content database, the search unit and the map information generation unit. The communication unit acquires place information indicating a place. The content database stores place information indicating a place and specifying information specifying an expression part where an expression related to the place appears in content in association with each other. The search unit acquires the specifying information stored in association with the place information indicating a place within a specified range from the place indicated by the place information acquired by the communication unit from the content database. The map information generation unit outputs the specifying information acquired by the search unit.

Abstract: An information providing device according to an aspect comprises: a reception unit which receives a page request for access to a web page of an auction site from a user terminal, the page request containing an identifier for specifying a user; a search unit which extracts a purchase history corresponding to the identifier from a purchase history memory storing purchase histories of products and which specifies a product having been purchased by the user and corresponding to a content of the web page; and a transmission unit which transmits product information and the web page to the user terminal in order to display the product information of the product specified by the search unit, along with the web page on the user terminal in a state in which the user can display the product for auction at the auction site.

Abstract: To provide a post display system, a post display method and a post display program capable of avoiding giving away the content even when a spoiler is posted, a reading terminal (1) functions as a post display system for displaying posted information posted for an electronic book and includes a terminal page management unit (12) and a display restriction unit (14). The terminal page management unit (12) specifies an unread part of the electronic book not read by a user who reads the posted information. The display restriction unit (14) performs control to impose display restrictions on posted information associated with the unread part among posted information associated with any part of the electronic book. An unread part not read by a user is thereby specified, and display restrictions are imposed on posted information associated with the unread part among posted information associated with any part of the electronic book.

Abstract: A web server 40 includes a keyword acquisition unit (43) that acquires first item information related to a first item shown on a web page displayed on a web browser of a user terminal (10), a related item acquisition unit (44) that acquires second item information indicating a second item (related item) related to the first item by referring to an item database (21) storing item information based on the first item information, and a related item transmitting unit (45) that transmits the second item information to the user terminal (10) so that the second item information is shown in a separate window displayed superimposed on the web page.

Abstract: It has been required to refold an inactive protein into an active protein with high efficacy. This problem can be solved by the method for producing a protein including a step of providing a porous body supporting an inactive protein in its mesopores, a step of applying a denaturant to the porous body supporting the inactive protein, and a step of changing the inactive protein to an active protein by removing the denaturant from the porous body.

Abstract: Various metal oxide nanosheets with uniform thickness under mild conditions and in a short time are provided. A mixed solution containing a surfactant such as laurylamine and a metal alkoxide are allowed to flow over water surface to obtain a composite nanosheet. The composite nanosheet comprises a lamella molecular film consisting of a surfactant, and a metal oxide nanosheet formed along the surface of the molecular film. If necessary, the composite nanosheet was separated and then immersed in a solvent in which the surfactant can be dissolved, to separate the metal oxide nanosheet from the molecular film.
