Abstract: This cellular tissue production method can produce a cellular tissue with high density and high shape retainability while the cell viability is maintained, and includes: a first application step of applying a first application liquid to an application target; and a second application step of applying and layering a second application liquid onto the first application liquid applied in the first application step, wherein the second application step includes subjecting an interface between the first application liquid and the second application liquid to gelation while the first application liquid is kept fluid.

Abstract: A cultivation greenhouse includes: an inner lining that forms a housing space for housing a plant to be a cultivation target, the inner lining tightly sealing the housing space; an outer lining that is disposed on an outer side of the inner lining to house the inner lining, the outer lining forming, with the inner lining, a circulation space for flowing outside air; and a circulation device that circulates air outside the outer lining into the circulation space and discharges the air to outside of the outer lining.

Abstract: Denitration catalyst unit, comprising two or more platy catalyst elements, wherein the platy catalyst element has an edge located on gas-inflow side, an edge located on gas-outflow side and edges located on either side of the platy catalyst element, the platy catalyst elements are piled so as to align the edges located on gas-inflow side and the edges located on either side of the platy catalyst elements respectively, each of the platy catalyst elements alternately has more than one flat part in the shape of a flat plate and more than one concavo-convex part in the shape of platy convex strips on the upper and lower surfaces, the platy convex strips are parallel to one another and are obliquely disposed at an angle ? of not less than 50° and not more than 85° to an extending direction of the edge located on gas-inflow side of the platy catalyst element so that a ridge of the platy convex strip on the upper surface of one of the platy catalyst elements intersects with a ridge of the platy convex strip on the l
