In this paper, a new high sensitivity potentiometric pH-electrode with a response in the acid region is proposed. It consists of a PbO(2)-paraffin matrix deposited on graphite. Its simple construction and studies of some variables at 0.5molL(-1) ionic strength are reported. A direct relationship between the electric potential difference and the solution pH(More)
Morphometric studies performed in several species of Neotropical social wasps from the tribe Epiponini showed that in some species there are marked differences between castes, while other species present highly distinct castes with differences only in ovarian development. This work analyzed females from six colonies of the social wasp Leipomeles dorsata(More)
