Abstract: A means of creating a navigable path, passage, canal, or channel, for marine craft, boats, or ships, through solid ice, during seasonal, arctic, or natural winter freezing conditions by the use of loose, or captive, hollow, or solid, balls, spheres, or discs made of plastic, rubber, metal, wood or wood composite, packed and nested together at a specified depth and placed on the surface of the water within the width and length of a proposed navigable channel, formed by existing concrete, or steel walls, or by cutting a path through solid ice with rotary or chain saws, or creating a passage with vertical, floating mesh netting, at the beginning of the winter freeze. The inventor has established that loose of captive, frozen, closely packed nested balls, create a web of interlocking filaments of ice structure between them, but having no consistent thickness in any direction, the structure remains weak and susceptible to pressure. or direct force and is easily broken up by weight, or the bow of small harbour craft. Larger balls create a similarly weak ice structure. Although still subject to freezing, continuous use of the channel will change each time to break-up and churn the mush of water, ice fragments and moving or sliding balls, ensuring there is no impenetrable solid ice barrier to open water. Ball traps at each end of the channel determine that very few balls are lost, or drift away.

Abstract: The invention relates to a method and a device for detecting temperature-dependent parameters, such as the association/dissociation parameters and/or the equilibrium constant of complexes that comprise at least two components.  The first components which are situated in a liquid phase are connected to measuring points, preferably on a planar optical waveguide of a reaction carrier, produced by second components that are coupled to the solid reaction carrier and specifically bind to the first components, by means of a, preferably heatable, device for contacting the liquid phase and the reaction carrier, whereby complexes are produced. Fluorescent dyes which are bound to the first components and/or second components are excited in the surface area of the planar optical waveguide, preferably by means of the evanescent field of the excitation light that is coupled into the planar optical waveguide, for emitting fluorescence light. The emitted fluorescence light is detected in the area of the optical waveguide or by means of excitation light emanating from the area of the optical waveguide. Production or dissociation of the complexes comprising first components and second components is observed as a temperature function.
