DNA ligase LigE increases bacterial transformation with damaged extracellular DNA

FEBS Letters, EarlyView.
The DNA ligase LigE from the naturally competent Gram‐negative bacterium Neisseria gonorrhoaea increases transformation with cut extracellular DNA. This process is ATP‐dependent and relies on the catalytic activity of LigE; it also requires that LigE contains an intact periplasmic localisation sequence, indicating that ligE functions in the periplasm ...

Effects of mineralogical composition into the reactivity of calcinated ilmenite for chemical looping technologies

Journal of Materials Research and Technology
Ilmenite is one of the most promising oxygen carriers (OC) for chemical looping combustion (CLC) on a large scale. However, ilmenite samples from distinct mines submitted to diverse mineral processing procedures do not have homogeneous physicochemical ...

Porosity determination of pre salt core fragments by non-destructive pycnometry techniques

Heliyon
Core fragments are often excluded from routine core analysis (RCAL) due to their irregular geometry. It is estimated that more than 40 % of the core samples are disregarded, losing information about this part of the exploration well.
