In a series of seven column experiments, attachment of the bacteriophage PRD-1 and MS-2 to silica beads at pH's 5.0-5.5 was at least partially reversible; however, release of attached phage was slow and breakthrough curves exhibited significant tailing. Rate coefficients for attachment and detachment were on the order of lo4 and 10-6-10-4 s-l, respectively. Corresponding time scales were hours ...

Metallic strip flexible pipes (MSFP), a relatively new style of unbonded pipes, are considered as an attractive alternative to traditional submarine pipes. During its reeling operation, it will inevitably confront various complicated loads, which may affect the integrity and safety MSFP's utilization. In this paper, tension-extension moment-curvature relation MSFP were obtained by laboratorial ...

introduction: prefabricated metal and ceramic posts can be used with different kinds of core materials as an alternative to the conventional casting post and cores. it is unclear how these post and core systems can withstand different kind of forces in the mouth. the purpose of this study was to compare the fracture strength of endodontically treated, crowned maxillary incisors restored with ca...
