1. A hexasaccharide unit was isolated from the specific substance S. 10A from Pneumococcus type 10A (34) by hydrolysis with alkali followed by enzymic dephosphorylation. 2. The hexasaccharide was shown to be O-d-galactofuranosyl-(1-->3)-O-d- galactopyranosyl-(1-->4)-O-[d-galactofuranosyl- (1-->6)]-O-2-acet-amido-2-deoxy-d-galactopyranosyl- (1-->3)-O-d-galactopyranosyl-(1-->2)-ribitol.

1. The phosphate groups in the type-specific substance S. 10A from Pneumococcus type 10A (34) were shown to join the hydroxyl group at position 1 or 5 of ribitol and the hydroxyl group at position 5 or 6 of a d-galactofuranosyl residue in the next repeating unit. 2. A partial formula of the type-specific substance was derived.

Today, the current buffered router Synchronous Network on Chip architecture consumes significant chip area and power. Therefore, based on biased routing, buffer-less routers have recently been predicted as a possible solution, but they suffer from contiguous port assignments, slow critical paths, and increased latency. Asynchronous Network on Chip architecture emerges as the best option for avoiding glitches and consuming less power. A clock and data recovery circuit is used to recover the clock signal from the router-generated data and reduce power consumption in a Multiprocessor System on Chip. This paper proposes a clock and data recovery circuit design for an asynchronous Network on Chip. The proposed 4x4 Mesh router architecture implemented in this paper can process 64-bit of data samples with a depth of 64. When comparing the proposed architecture with the existing NoC architecture, the proposed architecture has shown a power reduction of 5times. The proposed architecture has consumed a total power of 0.103W.
