OBJECTIVE For the surgical treatment of congenital heart disease and in Ross procedure a valved conduit is frequently required. Since homografts are not readily available in every country, a reliable alternative is needed. We developed a novel technique to construct a valved pulmonary conduit with single point attached commissures (SPAC) in a simple and fast way from a small strip of autologous...

An effective description of water transport in the soil–plant–atmosphere continuum (SPAC) is needed for wide-ranging applications in hydrology and climate-vegetation interactions. In this contribution, the theory of water movement within the SPAC is reviewed with emphasis on the eco-physiological and evolutionary constraints to water transport. The description of the SPAC can be framed at two w...

We reported previously the cloning and sequence of the Bacillus subtilis infB gene which encodes the essential IF2 factor required for initiation of translation (K. Shazand, J. Tucker, R. Chiang, K. Stansmore, H. U. Sperling-Petersen, M. Grunberg-Manago, J. C. Rabinowitz, and T. Leighton, J. Bacteriol. 172:2675-2687, 1990). The location of the 5' border of the infB operon was investigated by us...

This paper investigates the survivable trafficgrooming problem for optical mesh networks employing wavelength-division multiplexing (WDM). In the dynamic-provisioning context, a typical connection request may require bandwidth less than that of a wavelength channel, and it may also require protection from network failures, typically fiber cuts. Based on a generic grooming-node architecture, we ...

This paper reports the implementation of Software Process Assessment and Certification (SPAC) model. In year 2006, the model has been validated in three software organizations for its practicality in the real world. Recently in year 2011, the SPAC model has been implemented again in one of the organizations participated in year 2006. This paper discusses the outcome from the current study and c...
