Se determinaron las especies de macrobentos en el estuario del río Chira entre octubre 2018 y mayo 2019. Se instalaron 8 losetas decerámica de 36 x 36 cm de color ladrillo cada 5 metros, en las zonas de baja profundidad del estuario, las mismas que fueron aseguradascon cuatro estacas de madera, se dejaron sumergidas a una profundidad de 20 cm en marea baja durante todo el periodo de investigacióny se retiró una mensualmente. Se determinaron 10 especies de macrobentos, distribuidos entre los Phylum Athropoda y Annelida, siendoel género Balanus el predominante y el que tuvo la mayor abundancia relativa de las especies encontradas. La variación de la salinidad sedebió a las precipitaciones estacionales, que es la principal causa de los cambios observados en la comunidad macrobentónica.

La identificación de especies en alimentos de origen animal presenta elevada importancia tanto en cuestiones relacionados con la calidad como con la seguridad alimentaria. La adulteración en los alimentos es relevante por motivos económicos, religiosos, legislativos o de salud pública. El objetivo de este estudio se centró en identificar especies animales (bovino, porcino y equino) en productos cárnicos a fin de determinar la adulteración en la venta de mortadela (MO), hot dog (H.D), chicharon de prensa (C.P), chorizo (CH) y jamonada (JA). El ADN fue extraído de 5 regiones diferentes de cada embutido y se realizó la PCR utilizando primers especie-específico. El amplicón de la PCR de la región especie-específico fue de 271, 212 y 145 pb para bovino, porcino y equino, respectivamente. El H.D fue el único producto amplificado por los primers específicos de bovino. El C.P y CH fueron amplificados por los primers de porcino, dado a que ambos productos contenían carne de esta especie. No se observó amplificación en MO, H.D y JA, pese a que estos últimos incluían a la carne de porcino según la etiqueta declarada por la compañía. Estos resultados muestran la existencia de adulteración en la venta de estos productos. Para el caso de los primers de equino, ningún producto cárnico ha sido amplificado. Se concluye que hubo presencia de adulteración en ciertos productos, lo cual representa un riesgo potencial para la salud pública y pérdidas económicas para los consumidores.

Pseudomonas sp. es una de las bacterias ampliamente estudiada en el manejo del medio ambiente por su capacidad biodegradativa, en ese sentido el objetivo de la presente investigación fue evaluar la eficiencia biodegradativa de cianuro por Pseudomonas sp. a diferentes tiempos de incubación. El estudio tuvo un diseño donde se empleó como grupo control solución salida fisiológica y un biorreactor con columna de burbujeo, cada biorreactor contuvo 450 ml de MBSMG a la concentración de 500 ppm de cianuro y a un pH de 8, con un inóculo a una concentración de 1,5 x 108 células por mililitro. La valoración de la concentración de cianuro se realizó mediante una titulación con AgNO3 y KI. Los resultados obtenidos muestran una eficiencia de biodegradación del cianuro del 92,3% a los 3 días de incubación, 85,8% a los 7,5 días y 75,9% a los 12 días; encontrándose también una correlación inversa de 0,985 entre la eficiencia de biodegradación y el tiempo de incubación de la bacteria mediante la Correlación de Pearson. Se concluye que la mayor eficiencia biodegradativa de la Pseudomonas sp. se presenta a los 3 días de incubación. DOI: http://dx.doi.org/10.17268/rebiol.2022.42.02.03

The purpose of this work is to analyze the concept of “being person” taking as a parameter the ideas of Edith Stein and José Ortega y Gasset on this matter. We will take the thought of a young Stein exposed in The Structure of the Human Person and for Ortega's we turn primarily to his article “Prologue for Germans” because there he makes a synthesis of his doctrine. Deepening this topic and its relationship with morality takes on special relevance, at a time when some recent currents of opinion intend to expand it to include certain classes of animals. Also, to evaluate how correct is the statement that free actions are the ones that form the person's being.

This text presents the foundation of the inductive method for teaching classical Greek, created by L. Mascialino and continued by V. Juliá and his various generations of disciples. It will be presented in three sections: the first shows the relevance and specificity of classical Greek teaching, and a brief description of the status of the grammatical discipline in its ancient origins, whose immediate reference was Dionysius Thracian’s Téchne grammatiké. The second highlights some relevant aspects of the method used, which is based on the shared structures of Indo-European languages. In connection, the last one briefly presents the notion of Indo-European on which, among other weighty issues, the inductive method is mounted and, in turn, explains its specificity and relevance.

In founding social and sexual relationships and practices, modern political philosophy started from an unquestioned phallocratic double assumption; namely: that it is necessary, in the first place, to divide human beings according to the active/passive binomial in order to, immediately afterwards, organize all economic, social and sexual human practices and relationships within a grid (or universal form of codification) of a juridical-contractual and fiduciary nature inherited from the old Roman law, whose formula is: do ut des; facio ut facias; do ut facias; facio ut des (I give so that you give; I do so that you do; I give so that you do; I do so that you give). But this division between active/passive subjects is a derivative or a product of a previous binomization and biunivocalization, held as a millennially unquestioned a priori; namely: the male/female division (which founds the so-called ‘sexual difference’). We will study how the modern legal-contractual conception of the subject, of sexuality, and of power will function as a form of universal codification with which all relationships and all human practices (current and possible) will be captured under the andromorphic and phallocratic model of exchange and contract (social and sexual). Under the rule of phallo-power (and assuming the current regime of production of human subjectivation), to what extent is it legitimate to say that there really is an “interchange” between human beings?

The article presents the main lines of historical-philosophical analysis of the book of Albert Camus, L' homme révolté, and puts them in relation to similar thesis by authors of the Frankfurt School, following the comments of Emilio Komar. It also points out the originality of Camus’ thought, his commitment to proposing ethical paths out of an era traversed by the violence sown by the political utopias of the 20th century.

This text explores in the selected works of Aristotle the connection of deliberation on the particular view of action and on the political view, and its rich anthropological and ontological background, not always addressed in the secondary bibliography. It highlights the many complex connections within the framework of Aristotelian anthropology, ethics, and politics. To this end, it focuses on the textual source, specifically on the selection of key passages from four Aristotelian texts: Nicomachean Ethics, Eudemian Ethics, Rhetoric and Politics. In the last two the political level of deliberation is analyzed and described, while in the previous two the level of individual praxis. The article is closed by a section that presents the connections between the two planes.

Images increasingly structure our experiences and our lives to the point of seeming to replace the experience of reality. I would like to discuss the question raised by Plato as to whether images do not have a deficient status and serve, rather than for the search for truth, for the manipulation of human convictions and desires. (1.) We would therefore do well to clarify the conditions of the connection between image and power. (2.) I will then link the concept of image with a theory of human image processing (3.). In this way, I will try to show that our cognitive system is capable of processing pictorial content in a special way, but ambivalent. This will be illustrated by the example of photography (4.).

Be aware Simondon’s poorly examined theory of imagination reveals a number of interesting possibilities. On the one hand, by grounding the function of images within the idea of a cycle, it provides an attempt of reconciliation between the assumptions that privilege either reproduction or creativity. On the other hand, his view might also be conceived as a serious alternative to various theoretical stances that characterize the problem of imagination strictly within a dichotomy between individual subject and social imaginaries. The paper proposes a reading of Simondon’s lectures given between 1965 and 1966 in Sorbonne in the broader context of his philosophy and outlines the role of imagination that exceeds imagining subject as well as establishing the mode of correlation with associated milieu, which performs the conditioning of its potentiality. Rejecting the primacy of representation, Simondon’s take enables one to draw the conclusion that imagination can be attributed to all living beings and conceived as the function of life.
