Abstract:
A synergistic antimicrobial composition comprising: (a) a hydroxymethyl-substituted phosphorus compound selected from the group consisting of tetrakis(hydroxymethyl)phoshponium salts and tris(hydroxymethyl)phosphine; and (b) tris(hydroxymethyl)nitromethane.
Abstract:
A wireless receiver is constructed to equalize a time-domain received signal, detect a plurality of symbols of the equalized time-domain received signal, and perform interference cancellation on the time-domain received signal. The interference cancellation can be performed using a partial result produced by an IDFT, and may use only neighboring symbols in a detected plurality of symbols. The resulting wireless receiver can be constructed to operate efficiently under a plurality of wireless standards.
Abstract:
A biocidal composition comprising 2,2-dibromomalonamide and sodium ortho-phenylphenol, and its use for the control of microorganisms in aqueous and water-containing systems.
Abstract:
Provided are biocidal compositions comprising 2,2-dibromo-3-nitrilopropionamide and a compound selected from the group consisting of 1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane; tris(hydroxymethyl)-nitromethane; and a hexahydrotriazine compound. The compositions are useful for controlling microorganisms in aqueous or water containing systems.
Abstract:
Methods are provided for controlling sessile microorganisms and removing biofilm from an aqueous or moisture-containing system. The methods comprise treating the system with an effective amount of a compound of the formula I: wherein X, R and R1 are as defined herein.
Abstract:
The present invention provides methods and formulations for reducing or inhibiting increase in the concentration of microbes in a water-based fluid. The methods and formulations of the present invention use glutaraldehyde and a hydroxymethyl-substituted phosphorus compound selected from the group consisting of tetrakis(hydroxymethyl)phosphonium salts, C1-C3 alkyl- and alkenyltris(hydroxymethyl)phosphonium salts and tris(hydroxymethyl)phosphine, in a ratio of hydroxymethyl-substituted phosphorus compound to glutaraldehyde in the range of about 2:1 to about 7:1, or about 3.5:1 to about 7.5:1. The methods and formulations of the present invention can be useful in treating water contaminated with aerobic or anaerobic bacteria in oilfield, natural gas field and other industrial applications.
