摘要:
An antimicrobial polymer is disclosed containing silicon-containing quaternary ammonium groups, the polymer including in its structure repeating units of Formula II: R3N+R0nSiX′4−nY− (II) wherein each R and each R0 is independently a non-hydrolysable organic group; each X′ is —OR′, —OH or —0—Si, wherein R′ is an alkyl group of 1 to about 22 carbon atoms, or an aryl group of 6 carbon atoms; n is an integer of 0 to 3; and Y is an anionic moiety suitable to form the salt of the repeating units of Formula II. Also disclosed are methods of making such a polymer and imparting sustained antimicrobial properties to a substrate using the polymer.
摘要:
A method of imparting sustained antimicrobial properties throughout a material or substrate using an antimicrobial polymerizable silicon-containing quaternary ammonium salt monomer in a solvent to form a quaternary ammonium salt solution; and mixing the silicon-containing quaternary ammonium salt solution with at least a second monomer or a polymer or coating a solid polymer. Depending on the nature of the second monomer or polymer and the reaction conditions; a copolymer with the first monomer or a homopolymer will form, such that a polymeric material, substrate or formed plastic product comprising the copolymer or homopolymer or blended with the coated concentrate will have sustained antimicrobial properties. This method can be used to make formed plastic products, thin layer films and other products having sustained antimicrobial properties.

A method for erecting structures composed of rammed-earth. A method of rammed-earth building construction is disclosed wherein walls are post-tensioned to enhance the ability of the wall to receive lateral loading without failing in tension.Post-tensioning rods are anchored to a concrete footing, and temporary forms erected alongside the footing. A protective sleeve is disposed around each post-tensioning rod. An earthen mixture is placed between the forms and around the sleeves, and rammed by compaction in a series of stacked courses. When the rammed-earth wall has obtained the desired height, it is topped with a concrete bond beam through which the post-tensioning rods extend. Using the bond beam as a brace against which a retaining plate may push, retaining plates are disposed upon the bond beam and around the threaded upper ends of each rod. A nut is threaded upon each rod and tightened against the retaining plate to draw the rod into tension. The torque applied to the nut thus loads the wall in compression via the plates and bond beam. Thus compressed, the rammed-earth wall is less susceptible to tension failure.

A conference engine operates in a multiplex processing scheme and requires a signal hardware summer to process all of the programmed conferences, all of the outputs and all of the input channels. The conference engine is only limited by the number of available input channels, the number of desired conference registers, the speed of the implementation, and the amount of memory available on the target system. The conference engine allows the number of available conference channels, the number of conferences per bridge and the number of bridges to be scaled. Each bridge contains a unique set of conference registers and has full access to the input channel data. Additional conference bridges are added by increasing the operating clock/memory to meet the processing requirements of the additional bridge. Conference registers in each conference bridge can be added/removed depending on the system requirements and are independent of the number of input channels.

An interactive television program guide application is provided that displays real-time information to a user. The interactive television program guide application may display alerts for indicating to the user the availability of real-time information. The interactive television program guide application may also display program listings with real-time information. In response to the user selecting a program listing, the interactive television program guide application may provide the user with an indication that real-time content related to the selected listing is available. In some embodiments, the real-time content is not the program corresponding to the selected program listing.

Liquid detergent compositions comprising a tripeptide enzyme inhibitors are provided. Methods of using the tripeptide enzyme inhibitor to stabilize liquid detergent compositions are also provided. Also provided are liquid detergent compositions wherein the tripeptide enzyme inhibitor at least inhibits the growth of at least one microbiological flora or fauna in the liquid detergent composition.
摘要:
A system and method for utilizing data stored in an EPG database for modifying advertisement information. In this way, a service provider and/or an advertiser can transmit a single advertisement to all the television stations regardless of their geographic location and other user specific information, and need not re-transmit the advertisement even if there is a change in the show's program description. When the advertisement is displayed, the correct updated information is retrieved from the EPG database and inserted into the advertisement. In one aspect, the present invention describes a method for modifying an advertisement in an EPG comprising the steps of: storing television schedule information in a first database; storing advertisement information in a second database; incorporating a portion of the television schedule information into a portion of the advertisement information to form a modified advertisement; and displaying the modified advertisement on a screen.
摘要:
A method for identifying human-resource work content to outsource offshore of an organization. The method is provided on a computer readable medium and includes the steps of identifying at least one task being performed by an organization; associating each identified task with a functional group within a plurality of functional groups related to the organization; determining information about individual human resources spent on each task; determining task information about human resources spent on the plurality of tasks, the task information based on the determined information about individual human resources spent on each task; using the determined task information to determine a value of each task; and outsourcing tasks having a value lower than a predefined limit to at least one of offshore and to a low cost supplier.
