A technique for evaluating computer system passwords is disclosed. The technique commences with obtaining, for each user of a computer system, password information generated by performing a security procedure on a password entry. The technique sequentially performs, for each user name, the security procedure on sequenced entries of a dictionary until either a match with the password information is detected or the sequenced entries are exhausted. The technique adjusts the sequence of a sequenced entry in the dictionary based on the number of matches detected for the sequenced entry, so that analysis of subsequent computer system password lists more rapidly identify passwords that may present a security risk to the computer system.

Fast microbial detection is accomplished without an indicator interfering with microorganism growth, without a culture medium degrading the performance of an indicator and without a color of test sample adversely effecting th microbial detection process. A container has a portion which accommodates a fluid culture medium, and has a portion which accommodates a CO₂ indicator. A CO₂ gas-permeable membrane isolates the CO₂ indicator from the fluid culture medium. The test sample is added in the fluid culture medium and then the container is sealed. The determination of the presence of microorganisms is accomplished by verifying a color change of a CO₂ indicator. The quantity of mircoorganisms is determined by measuring time from when the container is sealed until an indicator portion has a color change.

Provided are methods, compositions and articles of manufacture for detecting biomarkers indicative of exposure of a mammal to organophosphate compounds. The organophosphate compound includes pesticides, their metabolites and highly reactive organophosphoryl compounds. In one aspect of the invention, the biomarker results from interaction of the organophosphate compound with a polypeptide such as a serine hydrolase that includes acetylcholiestersae. The interaction of a biomarker so derived with a optical sensor comprising a receptor bound to a biopolymer results in an optical readout that reports the presence of the biomarker. In one aspect of the invention the receptor that is bound to a biopolymer, such as a poly-di-acetylene polymer, is a antibody that selectively recognizes the biomarker.

Disclosed are weld electrode plugs with polymeric inserts for loss-of-cooling detection, methods for making or for using such weld electrode plugs, and electric welding systems equipped with loss-of-cooling detection plugs. A disclosed loss-of-cooling detection assembly includes a plug that attaches to the weld shank of a welding system such that the plug fluidly couples to a coolant bore within the shank. The plug includes a plug body with a clearance hole extending therethrough. An insert detachably mounts to the plug such that the insert fluidly seals the clearance hole. This insert is fabricated from a polymeric material, such as a shape memory polymer, that alters a physical property, such as shape/size, of the insert responsive to changes in temperature and/or pressure of coolant fluid in the shank's bore. When this physical property is altered, the insert unseals the clearance hole causing a detectable leak of fluid from the shank.
