Abstract: The invention relates to the field of microbiology. A device for determining the sensitivity of microorganisms to antimicrobial drugs is configured in the form of a sterile plate made from a plastic material with indentations and is provided with a hermetically sealing element which covers the sterile plate. The indentations are filled with a solid culture medium containing agar. In different indentations, the culture medium contains antimicrobial drugs or combinations thereof or serves as a control. Between the plate and the hermetically sealing element, the device contains a moisture-absorbing material with a rigid mesh situated therebelow. The device is provided with a transparent protective lid made from a rigid durable plastic.

Abstract: A sealed, double walled water packet has an inner packet filled with potable water that has a porous outer surface layer containing absorbed water and an outer packet that encloses the inner packet and is connected to the inner layer. The inner packet (which may contain as little as a swallow of water) is connected to the outer packet (both of which can be made as envelopes with tearable sections or peel off corners) along one side or by a string so that the inner packet can be twirled or waved to cause rapid evaporation of water in the porous outer surface layer (which can include hydrogel) to thereby cool the potable water contained inside the inner packet before it is opened.

Abstract: A shoe storage device is provided having two rotation members that are rotated by a motor. The rotation members have swinging shoe platforms that are rotated such that each, in turn, is proximate a transparent access hatch such that the displayed shoes can be removed. The housing interior is illuminated by a light assembly and the interior air is humidified by a humidifier.
