This study focused on the evaluation of the machinability of different carburising steel grades by using a cemented carbide cutting tool during semi finishing of steel. The effect of the steel composition, microstructure and inclusion characteristics on the cutting tool wear in the soft part turning was evaluated for a reference steel R (0.028% S, 0.0009% O), a clean C steel (0.003% S, 0.0005% ...

Using a cDNA microarray consisting of 9198 expressed sequence tags, we surveyed the gene expression profiles in shoots and roots of a rice hybrid, Liangyoupei 9 and its parents Peiai 64s and 93-11 at 72 h after germination. A total of 8587 sequences had detectable signals in both shoots and roots of the three genotypes. A total of 1571 sequences exhibited significant (P<0.01) expression differe...

The aim of this study was to assess the ability of a new magnetic resonance (MR) angiography technique that does not use contrast enhancement medium to depict the vascularity of musculoskeletal neoplasms, and evaluate its clinical utility. We performed 3D fresh blood imaging (FBI) MR angiography in 57 patients with bone or soft tissue tumors, and the detection of vessels in and around the tumor...

Boron nitride nanotubes (BNNTs) [ 1,2 ] and boron nitride nanosheets (BNNSs) [ 3 ] have gained increasing attention for their structural similarity to carbon nanotubes (CNTs) and graphene, respectively. These BN nanostructures are wide-bandgap materials ( ∼ 6 eV), and their electronic properties are different from those of CNTs and graphene. In addition, BNNTs and BNNSs offer intriguing propert...

This chapter is concerned with the global regulation of animal health. Our case is a recent outbreak of avian influenza in South Africa’s ostrich industry. The analysis confirms an important theme in the emerging social sciences literature on biosecurity, i.e. the paradox of control methods that are rigid and inflexible, and diseases that are indeterminate. We also examine a second approach to ...
