The occurrence of Clostridium difficile in nine wastewater treatment plants in the Ticino Canton (southern Switzerland) was investigated. The samples were collected from raw sewage influents and from treated effluents. Forty-seven out of 55 characterized C. difficile strains belonged to 13 different reference PCR ribotypes (009, 010, 014, 015, 039, 052, 053, 066, 070, 078, 101, 106, and 117), w...

The ability to compare the performance of various NFS file server configurations from several vendors is critically important to a computing facility when selecting an NFS file server. To date, nhfsstone has been a popular means of characterizing NFS file server performance. However, several deficiencies have been found in nhfsstone. The LADDIS NFS file server benchmark has been developed to re...

Our method for information retrieval uses Robertson's 2-poisson model which is one type of probablistic approach. This method achieved a comparatively high score in TREC. In the NTCIR contest, we designed systems that could be used for adhoc retrieval and cross-lingual task. This paper explains the systems. key words 2-poisson model, adhoc retrieval, cross lingual retrieval G °±ê+HKsÞð ·Ù À U ...

We report the complete genome of a clinical strain Pseudomonas aeruginosa , CMC-097, which was isolated from ventilator-associated pneumonia patient with chronic infection. Illumina sequence reads were assembled using Geneious to yield 7,044,064-bp circular chromosome containing carbapenem resistance integron, In 2020 .
