摘要:
Client impersonation is recognized by an access control service using servicer credentials to allow a servicer to impersonate a user's context while requesting actions be performed on a computing resource. A servicer may be requested to perform an action through impersonation, granting access to the context of a user related to the computing resource. The computing resource receives servicer credentials and impersonation information from the servicer. After verifying the servicer's authorization to perform actions under the context of the user, the servicer may attempt to perform the requested action. The action may be logged as performed by the servicer impersonating the user. The user may also be billed for any costs incurred.

A database access system may protect a field by storing the field as one or more underlying fields within a database. The database engine may not have access to keys used to protect the underlying fields within the database, such as by encryption, while the database access system may have access to the keys. Underlying fields may be used to store protected data and aid in the querying of protected data. The database access system may modify queries to use the underlying fields, which may include encrypting query terms and/or modifying query terms to fit the use of the underlying fields. The database access system may modify query results to match the format of the original query, which may include decrypting protected results and/or removing underlying fields.
摘要:
Microbially produced ice nucleator mixtures which include either cell-free ice nucleator particle mixtures and/or whole cell ice nucleator mixtures. These mixtures are produced in methods which comprises culturing a selected microorganism in a two step process at a first temperature in a first step and at a lower temperature in a second step. The mciroorganisms include Erwinia, Pseudomonas and Escherichia coil. These methods produce ice nucleator mixtures having increased concentrations of ice nucleating sites per given weight or volume of ice nucleator material.

Disclosed are various embodiments for a log monitoring system to monitor the health of server log files. The log monitoring system may comprise at least one computing device and at least one application executable in the at least one computing device, where the at least one application being configured to generate at least one log health signal based on an analysis of the server log content generated by at least one host application. Furthermore, the application may generate a system integrity record based the at least one log health signal and an external signal, wherein the external signal embodies a system health metric of the at least one host application.

A pit blind for hunting and observing waterfowl includes a lightweight, low profile molded shell that is contoured for use by a single reclining individual. The shell is placed in a shallow open hole dug into the ground. A low profile cover is placed on top of the shell, with camouflage material placed on the cover to conceal the user. The cover is made of hinged panels, allowing the user lying in a horizontal prone position within the shell to rapidly push up the cover panel overlying the upper torso, sit up and take aim at approaching waterfowl. While reclining in the pit blind with a firearm, the user can point the barrel of the firearm through gun ports in the cover.
