Abstract: A storage controller and program product is provided for performing double authentication for controlling disruptive operations on storage resources generated by a system administrator. A first request is received from a first user for generation of a first key. A first key is generated, provided to the first user and associated with the storage resource. An input is received from the administrator, the input comprises a second key and a command for performing the disruptive operation. The second key and the first key are compared. It is verified that the administrator is authorized as an administrator of the storage resource. The disruptive operation is performed on the storage resource if the second key and the first key match and the administrator is authorized. Otherwise, the performance of the disruptive operation is denied.

Abstract: Print jobs received at a printer are assigned a reference which is incorporated as a representation of the reference in the printed print job. When the user recovers the printjob, the part of said print job incorporating said representation of said reference. is scanned back into the printer, which is then able to read the representation. By monitoring the time intervening between the printing of the print job and the scanning of the part of the print job incorporating the representation, the system is able to monitor the delay, and in a case where this exceeds a threshold to notify the user accordingly.

Abstract: Print jobs received at a printer are assigned a reference which is incorporated as a visible representation of the reference in the printed print job. When the user recovers the print job, the reusable print job addendum. is fed back into the printer, for reuse in later print jobs.

Abstract: A test kit for detecting an antibiotic or antibiotics containing a ?-lactam ring in a biological fluid is provided. The test kit includes at least one recognition agent, which is a receptor which specifically binds to antibiotics containing a ?-lactam ring and is obtained from Bacillus licheniformis. The test kit further contains at least one reference antibiotic immobilized on a solid support.

Abstract: The invention concerns a diagnostic kit for simultaneous assay of antibiotics of different classes. The kit contains a single reaction mixture containing at least one first labelled receptor, specific of recognition of ?-lactams, a second labelled receptor, specifically and competitively identifying a tetracycline and a biotinylated nucleic acid fragment, an antisulfamide antibody and a labelled sulfamide analogue; and a recovery system in the form of a solid support comprising a nitrocellulose membrane whereon are fixed in three separate testing zones, respectively an antibiotic with ?-lactam nucleus, an avidin and an antibody capable of specifically identifying the antisulfamide antibody, so that the labelling intensity detected on the recovery system at the three testing zones results independently from a competitive recognition of each antibiotic by its labelled receptor.

Abstract: The invention concerns a kit for detecting and/or quantifying a ligant (C), present in an analysis sample, by a receptor (A), characterized in that it comprises the following reagents: a single-stranded or double-stranded nucleotide sequence (B), and said receptor (A) consisting of a monomeric or multimeric proteinic entity including at least a first recognition site specific for said ligand (C) and a second recognition site specific for said nucleotide sequence (B); said ligand (C) being capable of positively or negatively modulating fixing of the receptor (A) by its specific recognition site on the nucleotide sequence (B).

Abstract: Disclosed is a process for determining the presence and/or amount of antibiotics containing &bgr;-lactam ring present in a biological fluid. The process complexes the antibiotic in the biological fluid with a known amount of recognition agent, and then places the mixture of the biological fluid and recognition agent in contact with an antibiotic on a support. A determination is made of the amount of the antibiotic present in the biological fluid. Also disclosed is a kit for use in the disclosed process.
