Abstract: A method, non-transitory computer readable medium, and apparatus that obtains a version history for a plurality of source code files associated with the computer program. At least one defect probability value is generated for each of the plurality of source code files using at least one metric and the obtained version history. One or more of the plurality of source code files having a higher risk of including one or more defects than one or more other of the plurality of source code files are identified based on the generated defect probability values. Information regarding each of the one or more identified source code files is output.

Abstract: Foamed two-part hard surface treatment composition which is formed by the admixture of two aqueous compositions, particularly (a) an aqueous alkaline composition comprising a bleach constituent, with (b) an aqueous acidic composition comprising a peroxide constituent, which compositions are kept separate, but which are admixed immediately prior to use or upon use to form a foamed hard surface treatment composition. The foamed two-part hard surface treatment composition are particularly useful in the cleaning of hard surfaces. Preferred foamed two-part hard surface treatment composition provide both a cleaning and sanitizing or disinfecting benefit to hard surfaces, while releasing little or no free chlorine gas to the ambient air.

Abstract: Alkaline cleaning and sanitizing compositions which are essentially free of chelating agents based on organic acid compounds, especially nitrogen containing chelating agents are provided, which compositions are particularly directed for the removal of soap scum stains on hard surfaces.

Abstract: Alkaline cleaning and sanitizing compositions which are essentially free of chelating agents based on organic acid compound, especially nitrogen containing chelating agents, which composition is particularly directed for the effective removal of soap scum stains on hard surfaces. The compositions of the present invention are particularly adapted to be used as a ‘ready-to-use’ type composition, as well as in a non-pressurized container which is supplied with a hand pumpable trigger spray apparatus. The present invention is also directed to the use of such a composition in the cleaning or sanitization of a hard surface, as well as methods for producing such compositions.

Abstract: Dilute aqueous compositions for removing soap scum consisting essentially of sodium carbonate, hypochlorite bleach, alkali metal hydroxide and a surfactant system consisting either of sodium 2-ethylhexyl sulfate and myristyldimethylamine oxide or of sodium 2-ethylhexyl sulfate alone.

Abstract: The inventive compositions are pourable aqueous bleach composition which contain abrasives, suitable for use in cleaning hard surfaces such as are found, for example, in lavatories and kitchens. The compositions of the invention show good shelf life, exhibit a high level of bleach stability and show good stain and soil removal, particularly from hard surfaces.

Abstract: A hard surface scouring cleaner composition comprises, by weight, (a) from 0.5 to 10% of soft abrasive particles, (b) from 0.5 to 2.5% of a chlorine-containing bleach, (c) from 0.2 to 3.0% of a thickening system comprising from 0.2 to 3.0%, based on the weight of the composition, of a cross-linked polyacrylate resin having a molecular weight in the range of 1,000,000 to 10,000,000 and from 0 to 2.5% of a synthetic smectite clay, (d) from 0.25 to 3.0% of a bleach-stable surfactant system comprising mainly anionic surfactants, (e) from 0 to 3.0% of an electrolyte selected from the group comprising sodium or potassium carbonates or silicates, and (f) sufficient amount of sodium or potassium hydroxide to provide a pH in the range of 11.5 to 13.5. These compositions have an apparent viscosity as measured on a Brookfield RVTDV-II with a #6 spindle at 50 rpm of from 0.5 to 7 Kcps and at 1 rpm of from 10 to 150 Kcps. The abrasive particles are preferably organic particles such as polyethylene or polypropylene.

Abstract: The present invention is a process for decreasing the concentration of a lignin-containing organic carbon in an aqueous system by a combination of ozone and hydrogen peroxide. The process is particularly useful for decolorizing lignin-containing aqueous solutions such as effluents from a pulp mill.

Abstract: A method for stabilizing hydrogen peroxide and the stabilized composition are claimed employing as a stabilizer a tin (II) salt of an acid selected from the group hydrofluoric acid, C6 to C17 saturated monocarboxylic acids and C2 to C6 saturated polycarboxylic acids, preferably oxalic acid. The tin content of hydrogen peroxide prepared from a tin (II) oxalate stock solution can be reduced by filtration to less than 1 mg/l if the tin oxalate stock solution has been properly aged.

Abstract: A high yield process is provided for treating lignocellulose food fiber to sanitize and bleach the fiber. The process is not only a high yield process but produces better or equivalent bleaching than alternative processes and further does not produce a waste disposal problem. The process also has the advantage of requiring very little energy compared to alternative processes.
