The invention concerns a method and means for control of traffic on a network by route control. The method and the means are based on functions in a traffic management system. The invention includes control of traffic from a first route, which passes a bottleneck, which can be a part of the network, e g a node or a link, with low capacity relative to the demand of traffic through the node or the link,-to at least another alternative route. That alternative route is separated from the first route at a node upstream of the bottleneck and is routing at least parts of the traffic another road passing the bottleneck of the first route. The method is built on several cooperating method steps and route control can be applied on several different hierarchic levels in the network, locally and more comprehensive. Essential method steps are estimating and controlling traffic margins on selected links and nodes in the network and utilizing those margins at the route control. The invention concerns traffic control of vehicles on a road network as a first hand application. But the method can also be used for other applications, as traffic control of data packets on a communication network.

Reduction of the likelihood of adverse inflammatory reaction to an implant or a transplant is achieved through several mechanisms including the catalysis of isomerization of peroxynitrite by a hydrogel-bound peroxynitrite isomerization catalysts. A second mechanism controls acceptable and unacceptable dimensions of surface features of implants, such as vascular stents. A third mechanism fabricates implants from materials which are substantially free from alloys transition metals which produce ions of which catalyze cell killing radical formation.

A sample cooling device is provided with, inside a sample storage which stores therein a sample rack, a first heat transfer member arranged at a position in contact with the sample rack, a second heat transfer member which cools the inside of the sample storage, and a condensate discharge mechanism which discharges condensate condensing on the second heat transfer member to the outside of the sample storage. An internal space of the sample storage is not sealed due to the existence of a leak path for air formed between the inside and the outside of the sample storage, the leak path including at least the channel. The sample storage includes an outside air introduction unit which forcibly blows the outside air into the internal space so that the pressure inside the sample storage becomes higher than the outside pressure thereof. The position and the direction of an outside air outlet of the outside air introduction unit inside the sample storage are set so that the outside air blown into the sample storage directly heads for the second heat transfer member.

An opening/closing valve (70) is provided in an oil feed pipe (43). When a liquid refrigerant enters from an oil separator (22) into the oil feed pipe (43), the temperature of the liquid refrigerant depressurized by the opening/closing valve (70) is suddenly lowered. When the lowering amount of the temperature detected by a temperature sensor (73) exceeds a prescribed value, it is judged that theliquid refrigerant enters into the oil feed pipe (43), and the valve (70) is closed.
