On-Line and Off-Line methods of simultaneously cleaning and disinfecting an industrial water system are described and claimed. The methods involve the addition to the water of the industrial water system of a Compound selected from the group consisting of the alkali salts of chlorite and chlorate and mixtures thereof; and an acid, followed by allowing the water in the industrial water system to circulate for several hours. The reaction of the alkali salts of chlorite and chlorate and acid produces chlorine dioxide in-situ in the water of the industrial water system. The chlorine dioxide kills microorganisms and the acid acts to remove deposits upon the water-contact surfaces of the equipment. An alternative method involves the use of a chelating agent and a biocide. Other possible cleaning and disinfection reagents may be added as needed including corrosion inhibitors, chelating agents, biocides, surfactants and reducing agents. These cleaning and disinfecting methods work in a variety of industrial water systems including cooling water and boiler water systems.

A tissue cell growth-promoting solution produced by this invention comprising water containing at least 1 to 500 ppm of active oxygen, when applied to a wound, supplies active oxygen originating from outside the biobody to supplement the active oxygen produced by the biobody's own protective system cells such as neutrophils and macrophages which gather at the wound site, thus increasing the concentration of active oxygen at the site of the wound, mimicking a state in which a large quantity of such bio-signals is secreted by the biobody itself, to promote the reconstruction of tissues, the action corresponding to the last of the four main steps involved in wound healing biochemical processes of "blood vessel reaction", "blood vessel coagulation", "inflammation", "reconstruction of tissues" and which would otherwise have to rely on the natural healing power of the biobody itself.

Rich-media applications are designed and created via the Internet. A host computer system, containing processes for creating rich-media applications, is accessed from a remote user computer system via an Internet connection. User account information and rich-media component specifications are uploaded via the established Internet connection for a specific user account. Rich-media applications are created, deleted, or modified in a user account via the established Internet connection. Rich-media components are added to, modified in, or deleted from scenes of a rich-media application based on information contained in user requests. After creation, the rich-media application is viewed or saved on the host computer system, or downloaded to the user computer system via the established Internet connection. In addition, the host process monitors the available computer and network resources and determines the particular component, scene, and application versions, if multiple versions exist, that most closely match the available resources.
