Abstract: Three-dimensional physiological matrices, methods, apparatus and kits for the expedited design, testing and evaluation of oncological remedies are provided. Key aspects of the inventions include matrices, and especially gel matrices, comprising one or more physiological fibers, which are adapted and arranged to provide conditions which permit behaviors, such as the movement of cells away from the margins of samples of target tissue through the matrix, to be evaluated in a manner that produces data useful for evaluating the oncological status and characteristics of the cells. In a further key aspect, the invention permits the in vitro testing and analysis of one or more conventional, experimental or theoretical therapies with respect to specific target tissues or cells. Among such therapies are therapeutic compounds and combinations thereof, radiation therapies, combinations of therapeutic compounds and radiation and numerous other possible therapies.

Abstract: Many types of stabilized lock-seam tubing are provided, as well as devices, apparatus and methods for producing such stabilized tubing. Advantageously, pinch-locked tubing according to the invention, which comprise interlocking, spaced pinched deformations of the lock-seam, greatly resists side-slip and other shape deformations, including those typically produced by cutting the tubing, and by ovalizing it. Many permutations of lock-seam pinching rollers and related devices for producing stabilized lock-seam tubing are provided. Pinch roller assemblies of the invention are suitable for use with conventional machines as well as machines adapted specifically for them. Apparatus of the invention are suitable producing helically wound or straight lock-seam tubing.

Abstract: The invention pertains to the conversion of waste materials derived from gypsum mining and processing, such as existing gypsum stacks, into waste containment or landfill facilities. Methods of the invention include the creation of waste containment facilities from existing gypsum stacks. Waste containment facilities created according to the invention can be used for the short-term, long-term or permanent storage of waste materials such as solid waste, community refuse materials, biomass, industrial waste, phosphate waste, and for composting or otherwise processing materials such as biomass. Containment facilities according to the invention can be lined or unlined, open or capped, depending upon the nature of the material to be resident in the containment facility and relevant governmental regulations. The invention also provides for drainage and recovery systems, monitoring, controlling and communication means, pumps and valving means, and any other means known in the waste containment facility field.

Abstract: Unitary void-maintaining geocomposites, and drainage systems utilizing those geocomposites, are provided for location below a road surface or below a large structure such as a building, retaining wall or parking lot. In some embodiments, the geocomposites include at least one fluid-transmissible layer, preferably a geotextile, attached adjacent an upper or lower surface, or both surfaces, of a polymer-based core element. In other embodiments, the core element is constructed such that no geotextile layer is needed. Characteristic of the core element is high transmissivity, that is, a high rate of horizontal flow of gases or liquids through the core. Characteristic of the at least one fluid-transmissible layer is high permittivity, that is, a high rate of vertical transmission of liquids and gases through the geotextile layer and into the core element. Also characteristic of fluid-transmissible layers of the invention is high exclusivity with respect to solid materials.

Abstract: A support for the head and neck comprises a cushion that extends upwardly from at least one of the user's shoulders to at least a portion of one of the user's ears. The support can include means for varying both the size and shape of the cushion so that its dimensions can be varied during use by an individual user and configured for use by many individuals. The support also can include means for attaching or enclosing one or more audio devices so that, for example, music or soothing sounds can be provided to one or both ears of a user. The invention is positioned at least partly by one or both of an adjustable attachment strap and a positioning scrim. The positioning scrim can be reversibly interposed between the user's back and a chair in which the user is seated.

Abstract: A weedless fishing lure is provided, comprising a float, a connector and an attractant, such as live bait or an insect replica, suspended above the surface of water in which the lure is borne. The float may be disguised as a water plant, fallen tree leaf, twig or other floating detritus or water creature. The attractant may replicate an insect such as a dragonfly, an insect larva such as a hellgrammite, or any other natural or artificial fish bait or prey. The lure is adjustable so that the relative position of the attractant or bait with respect to the float and the water surface may be changed depending on the particular fish sought or the conditions present. In one form, the specific gravity of the invention may be adjusted by adding counterweights to vary its floating and casting properties. In another form of the invention, a snag-free platform is provided comprising a float and a connector suitable for suspending above a body of water a hook or an attractant chosen for specific fish or conditions.
