1. Adição de superplastificante e anti-segregante à base de CMC em pastas de cimento para Poços de Petróleo
Oil well cementing materials consist of slurries of Special class Portland cement dispersed in water. Admixtures can be used to provide the necessary fluidity, so the material can be efficiently pumped down as well as penetrate porous rocks with controlled filter loss. Construction admixtures can be used to modify the properties of oil well cements provided

2. A novel family of TRF (DNA topoisomerase I-related function) genes required for proper nuclear segregation.
We recently reported the identification of a gene, TRF4 (for DNA topoisomerase related function), in a screen for mutations that are synthetically lethal with mutations in DNA topoisomerase I (top1). Here we describe the isolation of a second member of the TRF4 gene family, TRF5. Overexpression of TRF5 complements the inviability of top1 trf4 double mutants.
