Abstract: An arrangement for collecting a tissue or stool sample has a sample vial and a source of preservative fluid. A fluid valve controls a flow of the preservative fluid from the source of preservative fluid to the sample vial. An air equalization vent tube is coupled to the source of preservative fluid and an air valve controls a flow of air through the air equalization vent tube, the air valve and the fluid valve being actuated simultaneously. A scoop for collecting the sample is coupled to the sample vial coupler and extends into the sample vial. The preservative fluid flows from the source of preservative fluid to the sample vial by force of gravity upon actuation of the fluid valve. The air equalization vent tube transfers air from the sample vial to the source of preservative fluid upon actuation of the air valve.

Abstract: Buyers register their conditions of business objects they wish, in a database of the server in advance. If sellers have business objects to sell, they input the information of the business objects in the seller terminal, and then send it to the server. The server compares this business object information with conditions registered in the database, and selects the buyers whose condition corresponds to the business objects, and informs them about the business objects. The buyers who received the notice send the transaction reservation from their buyer terminals. The server informs the seller terminal about a state of the transaction reservations, which are sent from each of the buyer terminals. According to the state of the transaction reservation, the sellers select the way of transaction from selections that are prepared in advance, and then send it to the server. The server carries out processes that are necessary to accomplish the transaction in the way the sellers selected.
