摘要

Rolling torque for a seventeen passes, 125 x 125 mm HC SS316 billets rolled to a 16 mm diameter rod have been simulated. Torque calculations based on pressure exerted by the metal on the rolls and the area of contact during longitudinal rolling were obtained using the temperature values derived using the “Phantom Roll” method. Investigations were carried out for four different starting mean rolling temperatures between 988℃ and 1191℃ and at four different strain rates of 0.4s-1, 0.8s-1, 1.2 s-1 and 1.6s-1. Results obtained showed that for all cases, rolling in grooved rolls required higher torque compared to rolling in flat rolls. In general, it was observed that torque value increased as starting temperature decreases and for each set of starting temperatures, the torque value increases with temperature. In all cases, the torque values for grooved rolls were higher than those for flat rolls. This was due to the higher frictional effect, occasioned by the larger contact area between roll and stock. Results obtained also revealed an inverse relationship between strain rate and torque.

7. The bacterial identification and antimicrobial susceptibility testing are usually performed manually. Recently, the number of samples has increased and the need for automatification has grown. BioMerieux has investigated Vitek2 for this purpose. HUSLAB has assigned us to compare the identification and antimicrobial results with respect to routine methods and Vitek2. Furthermore, we evaluate test reactions, ESBL (Extended Spectrum Beta-Lactamase) production and the time what it takes to get results with Vitek2. In this study, we examined a total of 183 bacterial isolates including 76 ESBL-strains, 40 nonfermenting rods, 41 fastidious bacteria and 26 fresh clinical isolates. The results of routine methods were gathered from the patient database and following this, compared to the results given by Vitek2. Vitek2 correctly identified more than 96 f the ESBL-strains and fresh clinical isolates. The results of nonfermenting rods and fastidious bacteri a were 70 oncordant with those of the routine methods. Test reaction results of Api20E were 94 nd Api20NE 70 n concordance with Vitek2 results. Approximately 80 f all Vitek2 antimicrobial results and 90 f ESBL test results were correct. Compared to earlier studies, Vitek2 performed the tests faster than the routine methods. These results suggest that Vitek2 is capable of giving rapid and accurate results. However, nonfermenting rods and fastidious bacteria should be studied further. [O] . Järveläinen Marika, Roslund Iira, Silander Maarit 2006
