  • Patent number: 8376888
    Abstract: In one embodiment, a transmission includes: a wobbler having an outer periphery tiltable with respect to a wobble axis of rotation; a set of freewheeling gears disposed in a fixed relationship with respect to one another, each gear having a gear axis of rotation about which the gear may rotate different from the gear axis of rotation of each of the other gears; one or both of the wobbler and the set of gears rotatable with respect to one another about the wobble axis of rotation; and each gear operatively connected to the wobbler simultaneously with the other gears at a place on the periphery of the wobbler different from the place at which each of the other gears is operatively connected to the wobbler such that each gear rotates on its axis of rotation as the wobbler wobbles or as the wobbler induces a wobble in another part.

  • Publication number: 20110212443
    Abstract: The present invention pertains to a molecular biology-based method and kit for measuring the specific growth rate (or cell doubling time) of distinct microbial populations. The method and kit can be used to analyze mixed culture samples that have been exposed to chloramphenicol or other protein synthesis inhibitors for defined times. In a preferred embodiment, the method of the invention (also referred to herein as FISH-RiboSyn) is an in situ method that utilizes fluorescence in situ hybridization (FISH) with probes that target: (1) the 5? or 3? end of precursor 16S rRNA; or (2) the interior region of both precursor 16S rRNA and mature 16S rRNA. Images can be captured for a defined exposure time and the average fluorescent intensity for individual cells can be determined. The rate of increase of the whole cell fluorescent intensity is used to determine the specific growth rate.

  • Publication number: 20110151455
    Abstract: The subject invention concerns materials and methods for evaluating the susceptibility of bacterial cells to an antibiotic or other antimicrobial compound or agent. In one embodiment, a sample comprising a microbial population is exposed to an antibiotic of interest. The sample is then processed using FISH-RiboSyn methods to determine the specific growth rate of the antibiotic-exposed microbes as compared to an untreated control. The subject invention also concerns materials and methods for determining the most suitable and/or effective antibacterial treatment for a person or animal having a bacterial infection.

  • Patent number: 6589375
    Abstract: A low-solids gas generating composition and a method of generating a gas with low solids by preparing and combusting the low-solids gas generating composition. The compositions of the invention include a mixture of a basic copper nitrate oxidizer and a fuel selected for the group consisting of 5-nitro-uracil, guanidine 5-nitro-uracil salt, ammonium 5-nitro-uracil salt, aminoguanidine 5-nitro-uracil salt, hydrazine 5-nitro-uracil salt, triamino 5-nitro-uracil salt, guanidine 5-nitro-barbituric acid salt, ammonium 5-nitro-barbituric acid salt, hydrazine 5-nitro-barbituric acid salt, aminoguanidine 5-nitro-barbituric acid salt, triaminoguanidine 5-nitro-barbituric acid salt, and mixtures thereof, wherein the oxidizer-fuel mixture is within about 4 percent of stoichiometric balance, and produces no more than about 0.06 cubic centimeters of solids per gram of gas generating composition on combustion.
