Abstract: The present invention provides a composition for topical administration to the skin for treating and/or preventing a dermatological condition involving an abnormal decrease in the cell-to-cell adhesion between epithelial cells comprising a zinc salt which is at least partially soluble in water and an acid, wherein the composition has a pH less than or equal to 6. The dermatological condition is generally selected from eczema, dermatitis, atopic eczema, atopic dermatitis, non-atopic eczema, non-atopic dermatitis, seborrheic eczema, irritant contact dermatitis, allergic contact dermatitis, pruritus and sensitive skin. A preferred composition comprises zinc lactate, lactic acid and has a pH of about 4.0 to 5.0.

Abstract: A wellbore evaluation system evaluates mechanical wear and corrosion to components of a well system including a production tubing string positionable in a well and a sucker rod string movable within the production tubing string. A deviation sensor determines a deviation profile of the production tubing string in the well, and a rod sensor senses and measures wear and corrosion to the sucker rod string as it is removed from the well to determine a rod profile. A data acquisition computer is in communication with the sensors for computing and comparing the deviation profile and the rod profile as a function of depth in the well. A 3-dimensional image of wellbores, with isogram mapping, may be generated and examined over the internet.

A data acquisition computer is in communication with the sensors for computing and comparing two or more of the respective deviation profile, rod profile, and tubing profile as a function of depth in the well. A 3-dimensional image of wellbores, with isogram mapping, may be generated and examined over the internet.
