This study examined the role of spatiotemporal feature attribution in the perception of the visual size of objects. A small or a large leading disk, a test disk of variable size, and a probe disk of a fixed size were sequentially presented at the same position for durations of 16.7 ms with interstimulus intervals of 117 ms. Observers compared the visual size of the test with the probe disk. The...

The activity of sulfamethoxazole (SMX), trimethoprim (TMP), and the combination of the two was determined against a variety of anaerobic bacteria. Brucella agar was somewhat inhibitory for SMX and TMP but activity was good and equivalent in Diagnostic Sensitivity Test Agar (Oxoid) and Mueller-Hinton agar and the latter was selected for use in these studies. Agar dilution susceptibility tests sh...

Antimicrobial susceptibility testing for Helicobacter pylori is increasingly important due to resistance to the most used antimicrobials agents. Only agar dilution method is approved by CLSI, but it is difficult to perform routinely. We evaluated the reliability of E-test and disk diffusion comparing to agar dilution method on Helicobacter pylori antimicrobial susceptibility testing. Susceptibi...

A modified broth-disk elution method for routine susceptibility testing of anaerobic bacteria was compared with the proposed reference agar dilution method under study by the National Committee on Clinical Laboratory Standards. The broth-disk elution method used a 24-h test incubation period, Schaedler broth medium supplemented with menadione, and GasPak (BBL Microbiology Systems) incubation. R...

BACKGROUND/PURPOSE The modified Hodge test is a phenotypic test to detect KPC-type carbapenemase producers among Enterobacteriaceae, as recommended by the Clinical Laboratory Standards Institute. However, false positive results were reported. In this study, we aimed to large-scale investigate the characterization of the modified Hodge test-positive isolates of Enterobacteriaceae collected betwe...

A simultaneous combined pancreatic test can be performed in one morning with only one intubation of the duodenum. The test includes the measurement of exocrine pancreatic secretion of bicarbonate, enzymes, and radioactive selenium, pancreatic scanning, hypotonic duodenography, and cytology of the duodenal aspirate. In the first 70 patients it was found that a single secretion test was of only l...

introduction main part of energy consumption in agricultural mechanization is tillage operations therefore optimization of energy consumption in tillage operation is very important. a management method for system to optimize in agriculture is simple additive weighting (saw) methodology that this method can operate according to criteria of the systems. this method states that, which system has b...
