RESUMEN Este artículo aborda la violencia como problema filosófico desde dos enfoques de pensamiento ubicados en latitudes geo-históricas distintas. En primer lugar, se presenta a la Escuela de Frankfurt, a través de la obra Dialéctica de la ilustración (1947). En segundo lugar, desde América Latina se expone la Filosofía de la Liberación, a la luz de Enrique Dussel en los planteamientos de su obra El encubrimiento del otro: el origen del mito de la modernidad (1994). Ambos discursos articulan un análisis crítico del fenómeno de la violencia, diagnosticando los síntomas degradados del proyecto civilizatorio de la Modernidad.

ABSTRACT This article addresses violence as a philosophical problem from two approaches to thinking located in different geo-historical latitudes. First, the Frankfurt School is presented, through the Dialectic work of illustration (1944/1947). Secondly, from Latin America the Philosophy of Liberation is exposed, in the light of Enrique Dussel and the expositions of his work The invention of the Americas: Eclipse of "the Other" and the Myth of Modernity (1994). Both speeches articulate a critical analysis of the phenomenon of violence, diagnosing the degraded symptoms of the civilization project of Modernity.

Panstrongylus geniculatus (Latreille, 1811) is the triatomine with the largest geographic distribution in Latin America. It has been reported in 18 countries from southern Mexico to northern Argentina, including the Caribbean islands. Although most reports indicate that P. geniculatus has wild habitats, this species has intrusive habits regarding human dwellings mainly located in intermediate deforested areas. It is attracted by artificial light from urban and rural buildings, raising the risk of transmission of Trypanosoma cruzi. Despite the wide body of published information on P. geniculatus, many knowledge gaps exist about its biology and epidemiological potential. For this reason, we analysed the literature for P. geniculatus in Scopus, PubMed, Scielo, Google Scholar and the BibTriv3.0 databases to update existing knowledge and provide better information on its geographic distribution, life cycle, genetic diversity, evidence of intrusion and domiciliation, vector-related circulating discrete taxonomic units, possible role in oral T. cruzi transmission, and the effect of climate change on its biology and epidemiology.

This paper describes the design and evaluation of a broadside printed dipole array for WLAN applications. The technique used allows to design a reduce antenna to radiate walkways and corridors, like those found in malls. The array was built in traditional technology consists of substrate FR-4 and characterized by an anechoic chamber, checking its effectiveness for 2.4 GHz band. The experimental results differs only 1.18 dBi from maximum gain and 1.7 % from design resonant frequency.

Este artículo describe el diseño y evaluación de un arreglo de dipolos impresos Broadside con alimentación en serie para aplicaciones WLAN. La técnica utilizada permite diseñar una antena de tamaño reducido ideal para radiar en pasillos, como los presentes en centros comerciales. La antena diseñada fue construida en tecnología tradicional conformada por substratos FR-4 y caracterizada por medio de una cámara anecoica, comprobando su efectividad para la banda de 2.4 GHz. Los resultados experimentales difieren solo 1.18 dBi con respecto a la ganancia máxima y 1.7% con respecto a la frecuencia de resonancia diseñada.
