Libro del distinguido profesor, investigador y actor de teatro Juan Rafael Torres Hernández, conocido por su nombre artistico Rafael Hernández. Constituye un valioso aporte al arte y cultura sobre una base conceptual y de análisis profundo de la obra de Brecht y Vallejo y su relación con el Perú. Con prólogo de Marco Martos, presidente de la Academia de Lengua del Perú y prominente hombre de letras.

The treatment of corneal lesions continues to be a topic of great interest. However, despite the development of new technologies and due to the slow evolution and uncertain healing of corneal lesions, they still represent a public health problem since patients can be affected for life, affecting the family and the health system due to the costly and uncertain response to treatment. For this reason, the need arises to seek therapeutic alternatives to treat these patients.

The 2022 quarantine period exposed the need to design laboratory instruments that were accessible to students, allowing them to conduct experiments from home. Although many magnetism studies have developed manually displaced gaussmeters, only a few of them have been automated. Therefore, this study presents the design of a gaussmeter made with construction toy parts and an Arduino UNO development board to quantify the magnetic flux density in permanent magnets. To evaluate its operation, precision and robustness tests were carried out. In this way, the Kruskal-Wallis test showed similarity in the experimental readings with the WSH315 sensor between 1.62–3.54 cm. Meanwhile, the Wilcoxon-Mann-Whitney test showed limitations in terms of accuracy. And the Youden-Steiner test showed robustness to polarity rotation in the magnet at a distance of 1.19 cm with the AD22151 sensor. Finally, the ...

Recently, the agricultural zones of Carabobo present problems with the water available for crops influenced by the fluctuation between Precipitation and Potential Evapotranspiration. It is for this reason that the need arises to analyze the climatic types according to the degree of humidity. The Climatic Hydrological Balance methodology was used for 25 rainfall stations in Carabobo, Venezuela, for a period of common registration (1969 - 1999). The results show that four regions were found where humidity behaves differently, the greatest excesses are to the south of the state and it was found that the climatological stations located north of Carabobo have a greater annual deficit. The most relevant agricultural areas are represented by a water index of (-2.16 to -18.96); which determines a dry sub-humid climate with annual rainfall ranging between 921 mm and 1063 mm. This study generated ...

Orchid bees (Apidae: Euglossini) are endemic to the Neotropics, with 134 species recorded in Colombia. These bees are distinguished by being attracted to fragrances from various botanical families and play an important role in natural ecosystems. Research has primarily focused on these natural areas, which is why this study aims to evaluate the taxonomic diversity of orchid bees and their relationship to certain environmental factors in two peri-urban areas (Parque de la Iguana and Mirador de la Virgen) in the city of Yopal, Casanare Department, Colombia. Two types of sampling were conducted: transects (bottle method) and Zigzag, using eucalyptus, vanilla, eugenol, and methyl salicylate fragrances as attractants. The collected specimens were transported for taxonomic identification and preservation in the entomological collection. A total of 280 individuals (4 genera and 11 species) were...
