The concentration of arsenic in tissues of tilapia was evaluated and an estimation of the risks associated with the consumption of this fish was done, taking into account the guidelines established by FAO/WHO. The inductively coupled plasma mass spectrometry (ICP-MS) technique in kinetic energy discrimination (KED) mode was employed and certified reference materials were analyzed with recoverie...

During work on the control of human pediculosis Craufurd-Benson & Macleod found that body lice, which normally have a high resistance to derris, were rapidly killed when high-boiling tar acids were added to the insecticide. A similar effect was observed in experiments with the sheep ked, Melophagus ovinus, when mixtures of cresylic acid and diphenylamine were applied either as a dusting powder ...

In a simple prime-target auditory rhyming event-related potential (ERP) paradigm with adults and 6-, 7-, and 8-year-old children, nonword stimuli (e.g., nin-rin, ked-voo) were used to investigate neurocognitive systems involved in rhyming and their development across the early school years. Even absent semantic content, the typical CNV to primes and late rhyming effect (RE) to targets were evid...
