摘要:
File transitions are identified that are to be tracked and at least one element of metadata is generated that characterizes each identified file transition to be tracked. Upon receiving a request for historical transition information, elements of metadata corresponding to at least two instances of a tracked file are aggregated and information is provided responsive to the request that is derived from the aggregated elements of metadata. The action metadata may follow that history of each tracked file as well as the histories of copies of each tracked file over time. Thus, an operator can manage the infrastructure of a corresponding computing environment with knowledge of the current and historical activities of files.

A hand puppet in which a plurality of different facial components can be removably attached to a head portion to produce different characters, such as monsters, funny looking characters, science fiction characters, etc. The hand puppet has a relatively rigid head portion, and the facial components can be attached anywhere on the head portion, and in any orientation relative to the head portion. A sleeve depends from the head portion, and has an opening at its distal end, and into which an operator's hand can be inserted to support the puppet.The sleeve is preferably formed of fabric which depicts an outer garment for the puppet and the sleeve has a pocket for storing the detachable facial components. Further, the sleeve is designed so that when the pocket is closed, it is basically hidden from view. Thus, the detachable facial components that are not being used to form the puppet's face are stored in a way which does not detract from the appearance of the puppet, and yet makes them readily accessible for changing the puppet's face.

A clutch release mechanism includes an annular piston arranged to move an anti-friction bearing axially for operating a friction clutch between an engaged position and a disengaged position. The outer diametrical dimension of the anti-friction bearing is less than the internal profile dimension of the annular cylinder, whereby the bearing is movable into the space circumscribed by the cylinder when the piston is in its retracted position.
摘要:
An electric utility sub-station having two transformers which transmit electric energy to customers in different service areas. A throwover is provided which is operative, when a failure occurs in one transformer, to switch the load normally carried by the failed transformer over to the other transformer which then carries the load of both transformers. Operation of the throwover is blocked when the total demand load on both transformers exceeds the capacity of either transformer.

Virtual Machine (VM) images in a virtualized environment are updated through the use of patches. A virtualization data processing system includes a hypervisor that manages a VM image. The hypervisor is configured to retrieve a patch for an instance of the VM image from a secure site. The hypervisor blocks all other network access to the VM image. The hypervisor is configured to apply the patch to the instance of the VM image and unblock all network access to the VM image

The present invention provides a method of direct detecting of capsid proteins from intact viral particles using matrix-assisted laser desorption/ionization (MALDI) time-of-flight mass spectrometry, which enables viral proteins to be characterized at the femtomolar level in complex biological milieu with minimal or no cleanup.
摘要:
There are provided novel fluorogenic substrates comprising a ketoside formed between an N-acyl neuraminic acid and a highly fluorescent material containing a phenolic grouping. The presence of neuraminidase is detected by contacting the aforementioned fluorogenic substrate with a sample suspected of containing neuraminidase. Neuraminidase, if present, cleaves the ketosidic linkage, releasing the fluorescent material which is then detected by known methods. There is also provided a novel and efficient method of preparing such fluorogenic substrates utilizing cadmium carbonate as a catalyst.
