Abstract: A knee protection airbag device includes an airbag. When the air bag is accommodated, an occupant side wall portion and a vehicle body side wall portion are overlapped and expanded flatly and roll-folding is performed such that an upper edge side of a knee receiving portion side approaches a lower edge side of the mounting portion side, end side portions on left and right sides of the roll-folded roll folding portion are formed as folded portions which fold over a central portion near a center in a left-right direction of the roll folding portion to form a folding completed body. A joining between a first overlapping portion and a tip side part of the airbag is released when an inflation gas flows into the airbag and when a fold of a first fold is canceled and the first overlapping portion deviates from a rear area of the central portion.

Abstract: The present invention provides a method for preparing algal cells used for evaluating a toxicity of a chemical substance by delayed luminescence, the method comprising the step of freezing algal cells in a logarithmic growth phase.

Abstract: An object of the present invention is to appropriately and easily evaluate a photosynthetic function of a photosynthetic sample contained in an evaluation sample. An evaluation method for photosynthetic sample according to the present invention is for evaluating a state of a photosynthetic sample with a photosynthetic function based on temporal data of a luminescence amount of delayed luminescence emitted from the photosynthetic sample. First, characteristic values that indicate characteristics are determined for a plurality of time periods in the temporal data. An evaluation value is then computed by weighting the characteristic values. The state of the photosynthetic sample is then evaluated based on the evaluation value.

Abstract: The present invention provides a method for evaluating the toxicity of a chemical by using an alga, comprising: (a) a thawing step of thawing frozen algal cells by heating, and diluting the obtained suspension of the cells by adding a culture medium thereto; (b) a recovery culture step of culturing the algal cells obtained in the thawing step (a) to allow the algal cells to recover from the effects of freezing and thawing; (c) a confirmation step of collecting a part of the algal cells after the recovery culture step (b), diluting the part of the algal cells by adding a culture medium thereto, and measuring the amount of the luminescence of the delayed luminescence of the algal cells as initial value data; (d) an exposure step of mixing the algal cells after the confirmation step (c) with a solution containing a test substance to prepare an exposure sample, and culturing the exposure sample; (e) a measurement step of measuring the amount of the luminescence of the delayed luminescence of the exposure sample a
