Disclosed is an Environmentally Limited Viability System (ELVS) for microorganisms based on temperature differences between permissive and non-permissive environments. Viability of the microorganisms are limited to the permissive environment by specifically expressing one or more essential genes only in the permissive environment, or expressing one or more lethal genes only in the non-permissive environment. Environmentally Limited Viability Systems are also disclosed involving coordinate expression of a combination of required genes and lethal genes. Microorganisms containing an Environmentally Limited Viability System are useful for release into a permissive environment. Temperature regulated Environmentally Limited Viability Systems are particularly suited for use with recombinant avirulent Salmonella vaccines by limiting their growth to the warmer environment inside the host. Such vaccines can be administered to protect humans or warm-blooded animals against bacterial, viral, mycotic and parasitic pathogens, especially those that colonize on or invade through mucosal surfaces. This antigen delivery system can also be used for expression of gamete-specific antigens to induce immune responses to block fertilization, or to induce immune responses to tumor antigens. In the event that an individual sheds live vaccine into the environment, the presence of the ELVS prevents survival of the vaccine. When environmentally regulated lethal genes are present on an extrachromosomal element and are regulated by chromosomal genes, transfer of the extrachromosomal element to other microorganisms will be limited by unregulated expression of the lethal genes in the recipient microorganism.

A cryogenic system includes a housing of a cryogenic chamber, a cold source in the cryogenic chamber, and a circulation loop for circulating cryogenic fluid between the cold source and a component to be cooled in the cryogenic chamber. The component has an elongated thermally conductive structure extending to a warmer environment. For adjustable cooling of the structure, an incoming stream of the cryogenic fluid is directed along a length of the structure extending from the component, and this stream is split into a first outgoing stream at a first location from the component and a second outgoing stream at a second location further from the component, and an adjustable valve adjusts the fraction of the incoming stream that becomes the second outgoing stream.

A reinforcing bar binding machine is provided with a control unit operated in such a manner that at the time of turning on an electric power source switch, a setting position of a motor drive adjustment dial and a state of a trigger lever are read, and when the motor drive adjustment dial is at a specific setting position and when the trigger lever is turned on, a binding wire cutting mechanism is driven by a predetermined number of times for warming up the binding wire cutting mechanism. When the warming-up operation is carried out in a cold environment, it is possible to reduce the viscosity of grease coated on a mechanism portion. Therefore, it is possible to lower a viscosity of grease applied on a mechanical portion and conduct a reinforcing bar binding work without wasting a binding wire in the same manner as that in a warm environment.

This invention relates to the control of radiant thermal energy and more specifically to highly Thermal Infrared (IRT) reflective pigments for use in decorative coatings for buildings or other areas where the control of IRT energy and visual decoration are required. Control of the spread of thermal energy in domestic building through passive techniques reduces energy consumption by reducing reliance on heating in cool environments and cooling air-conditioning in warm environments. A number of paint formulations having low emissivity in the thermal infrared exist which are based on variants of conventional decorative paint fluids. There are a number of problems associated with such formulations such as susceptibility to damages and high emissivity for certain colour pigmentations. The present invention proposes a low emissivity flake (1) for use in a paint formulation which substantially overcomes the problems associated with the prior art.

An ambient light is produced by transmitting light from a light source through an optical diffusion layer and then through a wood veneer. The optical diffusion layer obscures the light source and distributes the light transmitted through the wood veneer. The light then filters through the wood veneer via the color and grain of the wood. The light emitted from the wood veneer has natural colors that produce a warm ambient light.

In systems and methods for freezing and subsequently thawing liquid samples containing biological components, a sample is fractioned into a very large number of small drops (10) having surface area to volume ratios of 1000 m-1 or greater. The drops are projected at a liquid cryogen (40) or at the solid surface of a highly thermally conducting metal cup or plate, where they rapidly freeze. The cold gas layer that develops above any cold surface is replaced with a dry gas stream (75). The environmental temperature experienced by the sample then abruptly changes from the warm ambient to the temperature of the cryogenic liquid or solid surface. To thaw drops with the highest warming rates, the frozen drops may be projected into warm liquids. The sample is projected with cold gas to the warm liquid, so that again there is an abrupt transition in the environmental temperature.

This invention relates prolonging operation duration of ambient air heated vaporizers of cryogenic fluids; and more particularly concerns a method for enhancing ice removal under such vaporizers. Ambient air vaporizers have been used in the past to convert cryogenic fluids into warm gas. Because of the very cold surfaces inherent in the construction of these vaporizers, they collect frost or ice, and are generally limited in the time they can be effective due to the reduction in heat transfer caused by the frozen atmospheric water collecting on vaporizer surfaces. Operators frequently seek to mitigate this effect by having multiple vaporizers, alternately switching units on and off, allowing them to defrost. A characteristic of these defrosting vaporizers, is the falling of the frost and ice off the heat transfer surfaces, collect at the base of the unit (the “Pile). This Pile of frozen water or slush generally can be melted by exposure to warm ambient air during the defrost cycle. The Pile also can be removed manually.
