Abstract: Provided are a method, target and application for NO accumulation to decrease invasiveness of Pseudomonas aeruginosa; achieving NO accumulation by means of external NO donors or disruption of internal NO metabolism in an environment where Pseudomonas aeruginosa is growing or being cultured, in order to decrease production by Pseudomonas aeruginosa of the invasion factor pyocyanin. Utilizing even micro-quantities of NO can significantly inhibit Pseudomonas aeruginosa PCN (PCN synthesis down 82% with 60 ?M SNP treatment); by inhibiting NO reductase, an enzyme related to NO metabolism, PCN synthesis can be significantly inhibited (the PAO1-?nor strain has 84% PCN reduction). Using NO donors or inhibiting enzymes involved in Pseudomonas aeruginosa NO metabolism as a means of combating bacterial infectious disease does not affect the body's normal microflora like traditional antibiotics.

Abstract: Techniques perform resource configuration. The techniques involve determining, for a resource quota checking task for a file system on a storage system, a current workload of the storage system; in response to the workload exceeding a predetermined upper threshold, performing the resource quota checking task with a first number of processes; and in response to the workload being below a predetermined lower threshold, performing the resource quota checking task with a second number of processes, the second number being greater than the first number. By adopting such a resource quota check technique, the resources of the storage system can be more reasonably utilized for the resource quota check.

Abstract: A method of applying a riblet structure coating on the internal surface of a pipe includes coating the internal surface of a pipe with a resin layer and applying a cavity mold having a reverse riblet pattern structure to the coated internal surface of the pipe. A flexible air bag is inserted into the interior of the pipe and charged with air to hold the mold against the coated internal surface of the pipe. The air bag may be charged with air for a sufficient amount of time to allow the coating to cure in the riblet shape of the mold. Afterwards, the air bag and the mold are removed from the pipe to yield a pipe coated with an internal riblet structure.

Abstract: Methods, apparatus, and systems for achieving privilege separation are provided herein. In an exemplary method, an operation-applying instruction sent by a first-type client can be received. According to the operation-applying instruction, it can be determined whether an operation corresponding to the operation-applying instruction is able to be executed. When the operation corresponding to the operation-applying instruction is able to be executed, an operation-executing instruction can be sent to a second-type client, such that the second-type client can obtain a privilege for executing the operation, according to the operation-executing instruction. A notifying instruction can be sent to a third-type client, such that the third-type client can obtain a notification that the second-type client has obtained the privilege for executing the operation.
