The history of aeronautical medicine in Venezuela

The Aerial Medical Service of the Ministry of Transportation and Communications of Venezuela was created on June 1949, and later became the Department of Aeronautical Medicine. Its functions include the medical examinations of future pilots, navigators and flight engineers. The importance of good mental and physical health in all flight and ground personnel to ensure the safety of air travel is discussed

A Vavilovian approach to discovering crop-associated microbes with potential to enhance plant immunity

Through active associations with a diverse community of largely non-pathogenic microbes, a plant may be thought of as possessing an “extended genotype,” an interactive cross-organismal genome with potential, exploitable implications for plant immunity. The successful enrichment of plant microbiomes with beneficial species has led to numerous commercial applications, and the hunt for new biocontrol organisms continues. Increasingly flexible and affordable sequencing technologies, supported by increasingly comprehensive taxonomic databases, make the characterization of non-model crop-associated microbiomes a widely accessible research method toward this end; and such studies are becoming more frequent. A summary of this emerging literature reveals, however, the need for a more systematic research lens in the face of what is already a metagenomics data deluge. Considering the processes and consequences of crop evolution and domestication, we assert that the judicious integration of in situ crop wild relatives into phytobiome research efforts presents a singularly powerful tool for separating signal from noise, thereby facilitating a more efficient means of identifying candidate plant-associated microbes with the potential for enhancing the immunity and fitness of crop species

Lacan y el Barroco

this paper describes some aspects of Lacan’s interpretation on the Baroque and his conception of the links between word and image. to do this I distinguish three different readings of seventeenth-century culture. the first, which belongs to the first period of his teaching, is organized from what Massimo recalcati called an “aesthetics of emptiness”. the second of his lectures, given at the seminar The object of psychoanalysis, is structured from the conceptualization of the gaze. the third, established in the seminar Encore, is centered on the body and the reflections on the real.en este trabajo describo algunos aspectos de la interpretación de Lacan sobre el Barroco y su concepción sobre los vínculos entre la palabra y la imagen. Para esto distingo tres lecturas sobre la cultura del siglo XVII. La primera, que pertenece al primer período de su enseñanza, se organiza a partir de lo que Massimo recalcati denomina una “estética del vacío”. La segunda, formulada en el seminario El objeto del psicoanálisis, se estructura a partir de la mirada. La tercera, establecida en el seminario Aun, tiene como eje el cuerpo y las reflexiones sobre lo real
