Pure palladium thorn clusters were synthesized using the electrodeposition method. The clusters were composed of several thorns growing on one basis. Each thorn was composed of hexahedral units with decreasing sizes. The whole thorn was a single crystal along the <220> direction. The cluster was synthesized by square wave electrodeposition. By changing the deposition factors, a mixture of thorn...

In this note we introduce Thorn classes of microbundles. We determine the Thorn class of the Whitney sum as the cup product of Thorn classes and state two applications ; one to Gysin sequences of Whitney sums and one to the Atiyah-Bott-Shapiro duality theorem for Thorn spaces (cf. Atiyah [2]). Thus our main result states tha t for microbundles /xi, JU2 over a compact (topological) manifold X, i...

BACKGROUND Thorn injuries are common in the desert Southwest; however, the frequency and microbiology of thorn-associated infections have not been systematically described. Most information comes from case reports describing infections from atypical or environmental microorganisms. Our aim was to summarize the spectrum of thorn-associated infections. METHODS We conducted a retrospective revie...

Infection is a leading cause of morbidity and mortality among haemodialysis patients. Some of the risk factors specific to this population include repeated access to the blood stream through venous cannulation for dialysis as well as a higher prevalent usage of prosthetic materials like haemodialysis catheters and arteriovenous grafts. In addition, defects in immunity and phagocytosis also cont...

Hierarchical optical interconnection networks have the potential of solving the communication bottleneck that has evolved in parallel processing systems due big increases in processor speeds. Hierarchical Optical Ring Interconnection Network (HORN) [12] is one network architecture that was proposed to provide scalability to a larger number of processing nodes (PNs) with low latency and high ban...
