This paper deals with acoustic communication in the Red-vented Bulbul Pycnonotus cafer.This species emits a high variety of vocal signals that can be classified on the basis of their acoustical features and context of production.Individuals sang throughout the year and most songs were discrete and stereotyped.The songs were composed of strophes (ph
Species level identification of Agromyzidae based on morphology is often challenging due to their small size and morphological homogeneity.DNA barcoding has been used regularly to assist with the identification of economically important species of Agromyzidae, but rarely as a tool for species delineation or identification in biodiversity surveys.Th
Bacterial conjugation is the main horizontal gene transfer route responsible for the spread of antibiotic resistance, virulence and toxin genes.During conjugation, DNA is transferred from a donor to a recipient cell via a sophisticated channel connecting the two cells.Conjugation not only affects many different aspects of the plasmid and the host,
The method of conformal transformation has been widely applied to the research of devices using ponderomotive action of the magnetic field.This method enables the analysis and calculation of stationary 2D electric and magnetic fields meeting the Laplace equation.It allows essential simplification of the problem of the field calculation.However, its
This paper focuses on the ditransitive construction of Brazilian Portuguese, aiming at examining its semantic evolution.To this end, it compares manifestations of this construction in the 18th and 20th centuries in order to investigate whether there has been a change in its morphosyntax and in the semantic class of the verbs that instantiate it.The
