  • Publication number: 20230368230
    Abstract: A tool, method, and system for assessing an incremental value of one or more items in an item assortment are disclosed. The tool can receive historical purchasing data, which can include a plurality of customers purchasing one or more items of a plurality of items in an item assortment. The tool can use the historical purchasing data for the plurality of customers to simulate execution of removal of an item from the item assortment, wherein removal of the item from the item assortment causes an incremental loss associated with the item. The tool can order any number of items of the historical purchasing data. The tool can execute scenario simulations, and the tool can account for probabilities when interacting with the historical purchasing data. The tool can display assessment data and receive inputs via an interactive user interface. The tool can launch the assessment data in a downstream application.

  • Publication number: 20060165747
    Abstract: An activator comprising a biocompatible base and a known fungicide in the form of an acid salt are mixed together by the user shortly before being applied to the infection so as to react them chemically to produce the free base of the fungicide thereby rendering the composition capable of penetrating throughout the infected tissue. The free base form has been found to be much more lethal to the fungal infection, particularly in the treatment of onychomycosis. The activator is formulated to be mixed within a few days of or just before application with the fungicide, e.g., terbinafine hydrochloride (an acid salt). Although the free base is subject to degradation and has a shorter shelf life, it was found that mixing just prior to use eliminates problems that could be caused by degradation of an active ingredient. A preferred activator solution also contains a penetration enhancer and a tissue softener.

  • Publication number: 20040071757
    Abstract: The present invention provides a method for preventing a respiratory infection in a mammal at risk thereof. The method includes contacting a live respiratory pathogen at risk of entering the respiratory tract of the mammal with a therapeutically effective amount of an essential oil. The live respiratory pathogen is inactivated upon contact with the essential oil. The source of the essential oil is a patch located in the vicinity of the nasal passageway of the mammal. The present invention also provides a kit that includes the adhesive patch, a mask for placing over the nasal passageway, packaging material, and optionally instructions for using the adhesive patch and mask.

  • Patent number: 6620436
    Abstract: The invention provides a mixing and dispensing pouch for applying a wound dressing onto a wound. The pouch includes a pair of superimposed sheets, e.g., of plastic film, connected together at their edges. A pressure-rupturable seal is located between the super-imposed sheets and extends from one edge of the package to the other to form two compartments. The pressure-rupturable seal can be forced open manually by applying pressure on the exterior of the package with the hands so as to increase the hydrostatic pressure in a liquid, e.g., water contained in one compartment of the package causing the seal to rupture and the liquid to spurt through the ruptured seal, mixing with a dry wound dressing contained in the other compartment. If required, additional kneading of the package with the hands will mix the wound dressing for use as soon as it is expelled from the package.
