(Elsevier Science Inc, 2018-05)
A new phenoxo-bridged diMnIII complex, Na[Mn2L(OH)2(H2O)2]·5H2O (1), obtained with the ligand L5− = 5‑methyl‑2‑hydroxo‑1,3‑xylene‑α,α‑diamine‑N,N,N′,N′‑tetraacetato, has been prepared and characterized. Mass spectrometry, ...
Preliminary assays for the development of a probiotic for goats
(EDP Sciences, 2004-09)
In order to determine probiotic properties, 137 strains of lactic acid bacteria from the feces of Creole goats were screened, only six were resistant to pH 2.0 and bile salts (0.3%). Three strains identified as Lactobacillus ...
A theoretical model for predicting the behaviour of btex in the unsaturated zone and groundwater
(Universidade Federal da Paraiba, 2021-12)
Fuelling stations are one of the most important forms of soil and groundwater contamination in urban areas around the world. In this work, a mathematical model was applied to assess the risk of physical media contamination ...
