Streptococcus mtttans MT814S and Streptoeeceus sebrinus 6715DP and un sucrose-dependent adherence ot' the bacterial celLs }vere examined in vitre. The g!ucan synthesis by the bacterial glucosy]transferase "'as strongl)' inhibited by (-)-epicatechin gallate (ECg) and (-)-epigallocatcchin gallate (EGCg), thc main components ef the tea polypheno]s. It was also demonstrated that ECg and EGCg interf...

Wireless sensor and actor networks (WSANs) are among the most addressed research fields in the area of computer science in recent years. WSANs are composed of possibly a large number of tiny, autonomous sensor devices and resource rich actors equipped with wireless communication and computation capabilities. In WSANs, actors collect sensor information and respond collaboratively to achieve an a...

ABsrnAcr.-Rafinesque's big-eared bats (Cc1)'llOrhinus mjinesquit) use bridges as day roosts in parts of their range, but information on bridge use across their range is lacking. From May to Aug. 2002 we surveyed 1129 bridges (12.5%) within all 46 counties of South Carolina to determine use and selection of bridges as day roosts by big-eared bats and to document their distribution across the sta...

We have applied the sol-gel process to generate optical microstructures in glass using in-house developed sol-gel materials. The synthesis of our sol-gel glass materials is based on the formation of particles of controlled size from organo-metallic compounds. The overall shrinkage during annealing of the gel material is negligible and does not imply crack formation. Silica, titania and binar y ...

This paper extends results of [1], [2], of Goldstein, and [3] of Vainberg concerning steepest descent and related topics. An example Is given taken from a simple rendezvous problem in control theory. The problem is one of minimizing a norm on an affine subspace. The problem here is solved in the primal. A solution in the dual is given by Neustadt [4]. I. GENERATION OF MINIMIZING SEQUENCES Let E...
