Production of Rca

Concrete pavement recycling is a relatively simple process that involves breaking, removing and crushing hardened concrete from an acceptable source to produce recycled concrete aggregate (RCA). The formal process of RCA production typically involves an initial evaluation of the existing source concrete; pavement preparation, which may include removal of an asphalt overlay; pavement breaking, r...

Regulator of complement activation (RCA) locus in chicken: identification of chicken RCA gene cluster and functional RCA proteins.

A 150-kb DNA fragment, which contains the gene of the chicken complement regulatory protein CREM (formerly named Cremp), was isolated from a microchromosome by screening bacterial artificial chromosome library. Within 100 kb of the cloned region, three complete genes encoding short consensus repeats (SCRs, motifs with tandemly arranged 60 aa) were identified by exon-trap method and 3'- or 5'-RA...

RCA models with GARCH innovations

Rapid developments of time series models and methods addressing volatility in computational finance and econometrics have been recently reported in the financial literature. The non-linear volatility theory either extends and complements existing time series methodology by introducing more general structures or provides an alternative framework (see Abraham and Thavaneswaran [B. Abraham, A. Tha...

RCA-specific oligonucleotides for FISH

Quantification of RCA phylotypes We developed a specific PCR approach to estimate the abundance of the RCA phylotypes relative to total bacterial 16S rRNA genes based on serial dilution of extracted DNA. Alternate 1:5 and 1:2 dilution steps to extinction were applied in triplicates, to 10-fold dilution or higher. PCRs with bacterial and RCA-specific primers were performed simultaneously using 6...
