Abstract:
An improved method of detecting an enzyme in a sample, which enzyme is capable of adding or removing a chemical moiety to or from a nucleic acid molecule, thereby conferring the nucleic acid molecule with the ability to be extended to generate a novel detectable nucleic acid molecule, comprises the steps of allowing the sample to be tested for the presence of the enzyme to interact with the nucleic acid molecule; and testing for interaction of the enzyme with the nucleic acid molecule by detecting the novel nucleic acid molecule generated only in the presence of the enzyme. The preferred enzyme is a phosphatase. The methods have a number of applications, for example in enhancing the sensitivity of immunoassays, for detecting pathogen associated phosphatase, for diagnosing certain conditions and for detecting specific contaminants in a sample.

Abstract:
A method of detecting a molecule associated with viability of one or more cells or organisms in a sample comprises the initial step of contacting the sample with an enzyme, which enzyme is capable of adding or removing a chemical moiety to or from a nucleic acid molecule in the presence of the molecule associated with viability of the of the one or more cells or organisms. This thereby generates a novel detectable nucleic acid molecule. The next step involves detecting the presence of the molecule associated with viability of the one or more cells or organisms by detecting the novel nucleic acid molecule generated only in the presence of the molecule associated with viability of the one or more cells or organisms. A most preferred molecule associated with viability is ATP, although NAD may also be detected. A preferred enzyme for use in the methods is ligase. The method has numerous applications, in particular in monitoring viability of cells, toxicology testing and determining whether there is contamination in a sample or on a surface. Kits are also provided for carrying out the methods.
Abstract:
A weld process cuitable for repairing precipitation-strengthened superalloys, and particularly gamma prime-strengthened nickel-based superalloys. The process entails forming a weldment in a cavity present in a surface of an article formed of a precipitation-strengthened superalloy. The cavity has a root region and a cap region between the root region and the surface of the article. A solid body formed of a superalloy composition is placed in the root region of the cavity so as to occupy a first portion but not a second portion of the root region. A first filler material formed of a solid solution-strengthened superalloy is then weld-deposited in the second portion of the root region. Subsequently, a second filler material formed of a precipitation-strengthened superalloy is weld-deposited in the cap region of the cavity.

Abstract:
A phased antenna array is disclosed. The phased antenna array is composed of one or more modules and has a plurality of antenna. The array has a plurality of antenna configured to operate as an array and each module has at least one antenna. The modules have a substrate that supports the antenna, a microelectronic device for sending signals to or receiving signals from said antenna and conductive traces that connect that antenna to the microelectronic device. In those embodiments where the phased antenna array has more than one module, a common substrate supports the one or more modules. A combination of circuitry and interconnects achieves the desired electrical interconnection between the modules.
Abstract:
The invention includes an integrated toolset of software development aids for testing of software systems directed toward the production, access, management, and retrieval of stored data by providing a fast and efficient means for a developer to recreate production data within a testing environment. The toolset consists of components which, when combined, provide an interactive on-line system where a developer is provided with access to low volume, high-quality, depersonalized, and targeted data with referential integrity and is suitable for most testing needs.
Abstract:
A method of assay for the outcome of a reaction comprises conducting a reaction between a first reactant and a second reactant to produce from the first reactant a product having at least one new structural feature not present in the first reactant or the second reactant, e.g. by cleaving the first reactant or adding to it, producing a multiple-phage tagged complex comprising at least two different viruses and said product or said first reactant, in which complex at least one of said viruses is connected to said product using a said new structural feature or is lost from said first reactant upon formation of said new structural feature, and determining the presence or amount of said complex by a dual-phage assay.
Abstract:
A vehicle safety restraint retractor comprising a spool (2) for storage of belt webbing (1), the spool being mounted for rotation about its axis (3) within the spool housing (4) the retractor comprising a resilient biasing member (10) urging one end of the spool towards a corresponding cover for the side of the retractor, for taking up axial tolerances in the spool mounting. The resilient biasing member (10) is preferably a wave washer spring positioned at the spring side of the spool, between the spool and the spool arbour cap (9) and covered with a spring cover (7). Such a wave washer reduces axial and radial float of the spool and thus substantially reduces levels of noise in normal operation of the retractor.
