Abstract

Elastic modulus measurements were made using a three-point configuration testing method. Samples of barium strontium titanate (BST) were made using a regular powder pressing, sintering, pelletizing, and sawing method (pelletizing method), as well as a tape casting technique. Samples of aluminum oxide (alumina) were made by a tape casting method. For BST, a value of elastic modulus between 99 to 114 GPa was obtained for the pelletizing method and 161 GPa for the tape casting BST material. For the alumina, an average value of elastic modulus of 249 GPa was measured., The original document contains color images.

7. Comparison of Two DNA Extractions and Nested PCR, Real-Time PCR, a New Commercial PCR Assay, and Bacterial Culture for Detection of Mycobacterium AviumSubsp. Paratuberculosisin Bovine Feces

Abstract

In this study, 5 combinations of 2 DNA extractions and 3 polymerase chain reaction (PCR) techniques were compared with culture for the detection of Mycobacterium paratuberculosisdirectly from bovine feces. These combinations included a new commercial extraction technique combined with a commercial PCR/Southern blot technique, nested PCR (nPCR), or real-time PCR, and a university-developed extraction combined with nPCR or real-time PCR. Four of the 5 combinations had statistically similar sensitivities between 93% and 100% and specificity between 95% and 100%, when compared with culture results from 63 bovine fecal samples. These results indicated that using a commercial extraction with a commercial PCR/Southern blot, nPCR, or real-time PCR, or a university-developed extraction with real-time PCR would result in similar sensitivities to culture for the identification of M. paratuberculosisfrom bovine feces and are valid alternatives to culture.
