Efecto sinérgico de distintos extractos vegetales y Bacillus thuringiensis var. israelensis para el control de Aedes aegypti (L.) (diptera, culicidae)
Published 2020“…Preliminary tests to evaluate the larvicidal activity of three commercial plant extracts and nine methanolic extracts at concentrations of 50 and 500 ppm were performed, from which the methanolic extracts of Persea americana, Heliopsis longipes, Piper nigrum and Curcuma longa were selected by present the greatest larvicidal activity. …”

Failure analysis of the fasten system of wheels used in mining pickup trucks
Published 2017“…In this work, the causes that promote failure of the fasten system and subsequent ejection of the wheels of passenger pickup trucks used in open-pit mines are analysed. By means of scanning electron microscopy, optical microscopy analyses and hardness tests, it was found that failure of the fasten system is characterised by a series of synergetic steps that include, the plastic deformation of the lug nuts caused by deficient tightening practices, fatigue and plastic deformation of the bolts. …”
