Abstract: A security device, comprising, a bolt, comprising, a head, wherein the head comprises at least one functional marker; and a hollow cylinder, the hollow cylinder comprising a bolt internal threaded surface and a bolt external threaded surface, wherein the bolt internal threaded surface extends through the head; and a nut, comprising, a first nut cylinder, wherein the first nut cylinder is internally grooved threaded and of the same diameter as the bolt external threaded surface; and a second nut cylinder, whereby the second nut cylinder is capable of containing the head of the bolt when the bolt external threaded surface is securely screwed into the first nut cylinder. A bolt, the bolt further comprising at least one functional marker, and where the bolt is externally threaded in reverse.

Abstract: Composite particle comprising a zinc containing compound such as zinc oxide and a noble metal such a platinum, and process for fabrication thereof. The particles facilitate simultaneous controlled introduction of the zinc and noble metal species into a nuclear reactor.

Abstract: A method is provided for use in distributing access to a data item. The method includes allowing multiple transfers between computers of a single instance of permission to gain access to the data item, the transfers occurring across data connections and including a first transfer between a first computer and a second computer and a subsequent transfer between the second computer and a third computer, wherein at any one time only one computer retains the instance of permission and is able to use the instance of permission to gain access to the data item.

Abstract: Provided are methods and systems for generating nanoparticles from an inorganic precursor compound using a hydrothermal process within at least one CSTR or PFR maintained at an elevated temperature and an elevated pressure and a treatment vessel in which this reaction solution can be applied to one or more catalyst substrates. In operation, the reaction solution may be maintained within the CSTR at a substantially constant concentration and within a reaction temperature range for a reaction period sufficient to obtain nanoparticles having a desired average particle size of, for example, less than 10 nm formation and/or deposition. Variations of the basic method and system can provide, for example, the generation of complex particle size distribution profiles, the selective deposition of a multi-modal particle size distribution on a single substrate.

Abstract: A method for mitigating stress corrosion cracking of a component exposed to a high temperature water in a high temperature water system is provided. The method comprises the steps of lowering corrosion potential conditions to a desired low corrosion potential in the high temperature water environment; and introducing a first material comprising zinc into the high temperature water environment, such that the desired low corrosion potential facilitates transport of the first material into cracks in a structure communicative with the high temperature water environment.
