The tilt container is given by the angle between the horizontal and the axis symmetry of the cylinder. Formulations are developed for three cases: i) the limits of the filled level are between the lowest point in the container and the corresponding level where a horizontal plane reaches the first wet height, ii) the filled level is given by the liquid height limited by the horizontal planes corresponding to the first and second wet heights, respectively; iii) the filled level starts at the horizontal plane corresponding to the second wet height and ending with the fill full of the container. The math expressions give the exact volume inside the container as a function of the known parameters of radius, length, and tilt of the cylinder, and the variable parameter represented by the filled level. Finally, these expressions are applied using critical and regular dimensions of the recipe in the substance’s transportation, the graph volume vs filled level shows a behavior like a sinusoidal function.</em> <em>The results obtained lead to best practices in the design of cylindrical containers for the transport of substances and the implementation of security protocols.</em></p> Michelle Guadalupe Salas-Flores David Gasca-Figueroa Francisco Javier García-Rodríguez José Alfredo Ramos-Beltrán Jorge Macias-Aboytes Jafet Gassen Tula-Maldonado Copyright (c) 2024 Michelle Guadalupe Salas-Flores, David Gasca-Figueroa, Francisco Javier García-Rodríguez, José Alfredo Ramos-Beltrán, Jorge Macias-Aboytes, Jafet Gassen Tula-Maldonado 2024-05-25 2024-05-25 7 2 e349 e349 10.37636/recit.v7n2e349 Design of an energy absorption system for the landing of space exploration modules <p><em>Currently, space exploration is becoming an increasingly important activity since it allows increased knowledge regarding the formation of planets, economic activities (space mining) as well as a better understanding of geological and biological phenomena that allow the creation of space in the future of human habitats outside planet Earth. In this sense, one of the main problems of space exploration is associated with the safe landing of space probes. Based on the above, this article proposes the design of a passive type of energy absorption system based on plastic deformation of aluminum structural profiles. For this purpose, structural profiles with various geometric shapes were individually designed and evaluated using the Abaqus finite element software. The numerical evaluation was carried out through compression tests in conjunction with the calculation of the main impact resistance parameters. The results showed a better performance of the HSC-1 profile which obtained the best crushing force efficiency (CH-C) equal to 0.83. From the above, it was implemented in a discrete model of a generic space lander</em><em>.</em></p> Quirino Estrada-Barbosa Eladio Martínez-Rayón Elva Lilia Reynoso-Jardón Jesús Silva-Aceves Manuel de Jesús Nandayapa-Alfaro Lara C.

The characterization of the test area is carried out experimentally (using Prandtl tube) and numerically (using the commercial software Solidworks®); There is turbulent flow with recirculation at the entrance to the test area (the average speed is 4.18m/s and turbulence is 7%). With this visualization technique, the turbulent flow of different materials will be analyzed, simulating the behavior of pollutants that circulate through a prototype of a scale urban environment. Of the different materials tested, it was found that sodium bicarbonate presents the best characteristics to show the behavior of the flow around the model, clearly showing the formation of niches that simulate the accumulation of contaminants or the appearance of heat islands.</em></p> Oscar Adrián Morales Contreras Alejandro Alonzo García Juan Antonio Paz González Raúl Vázquez Prieto José Emilio López Escobar Copyright (c) 2024 Oscar Adrián Morales Contreras, Alejandro Alonzo García, Juan Antonio Paz González, Raúl Vázquez Prieto, José Emilio López Escobar 2024-05-29 2024-05-29 7 2 e347 e347 10.37636/recit.v7n2e347 Zinc oxide and silver oxide nanoparticles for skin sunscreen use <p><em>This article is about the use of nanoparticles for the development of sunscreen for skin care based on zinc oxide nanoparticles and silver oxide nanoparticles, with antioxidant, antimicrobial, anti-inflammatory, and healing effects, using ZnO which is proposed to be synthesized through the hydrothermal method and Ag2O nanoparticles by constant agitation, through characterizations such as XRD, Uv-vis, Raman and pH measurement, we will seek to obtain data about our nanoparticles and the final product which is a sunscreen for skin care; The characterizations will provide data such as the crystalline phase, the degree of absorbance, and the chemical structure of the nanoparticles. According to the literature, zinc oxide nanoparticles decorated with silver oxide nanoparticles for topical use have properties that generate the effects above (antioxidant, antimicrobial, anti-inflammatory, and healing). Currently, several sunscreens use zinc oxide and some others silver oxide, which is why the present proposal seeks to apply both materials at a nanometric scale for the elaboration of a cream that, it is expected, in the future can be used for people with skin problems, such as dermatitis, including the possibility of using it for diabetics.</em></p> Rodrigo Antonio Rojas Labastida Jazmín Viridiana Pacheco Julián Guillermo Amaya Parra Socorro Jiménez Valera Copyright (c) 2024 Rodrigo Antonio Rojas Labastida, Jazmín Viridiana Pacheco Julián, Guillermo Amaya Parra, Socorro Jiménez Valera 2024-04-02 2024-04-02 7 2 e283 e283 10.37636/recit.v7n2e283 Tecate anti-gender violence campaign: formal semiological analysis <p><em>This paper shows a practical example for the formal semiological analysis applying the method developed at the Escuela Superior de Artes Visuales in Tijuana, for the object of analysis consisting in an advertisement video for Tecate brand beer, that attempts to fight gender violence; our study problem was identifying the semiological factors that lead to the controversy between rejection and acceptance of said advertisement, given that the cause is just and the advertisement won several awards. Fundamental background for this work is the inception arsology as a science around 2001, its publication in 2008, the formalization of the Arsological Research Protocol for art and similar subjects, in 2016; as well as the development of a biological-evolutionary based formal semiology throughout the current century and its formalization with the publication of a manual (2017) and a treatise (2019). This study was conducted according to the methodology proposed at the Semiology for Artists and Designers (Jimenez, 2018) and the theory from where this method is derived (Jiménez, 2019); that in turn result from the seminal work of Rudolf Arnheim (1974) and others on the field of Gestalt, reinterpreted in light of the advances on neurophysiology of visual perception explained in works such as Vision and Art (Livingstone, 2002) or Sensory Perception (Schiffman, 2008); as well as a plethora of works in other fields such as Niko Tinbergen’s in biology –that got him the Nobel prize (1973) or in neurosciences and art perception (Ramachandran &amp; Hirstein, 1999), as well as many others in the fields of neurocognition, neurophysiology of perception, evolutionary ethology and other correlated ones. The exercise starts with the identification of the meanings created by the distribution in the perceptual field’s structural skeleton taking as reference Rudolf Arheim’s theories (1974), it proceeds with those from the spatial organization of figures; then, with the tonal composition of space; the figural interpretation from the neurophysiological principles of chromatic vision and, finally, the symbolic interpretation according to the conventions shared by the given group of people. The results of the work give indication on the possibility that the advertisement in question codifies a message that is different –on a formal level– from the one the concepts intend to convey and that it is to that other implicit message the audience reacted to in an unfavorable way. We conclude that the independence between the formal and symbolic messages is increasingly more evident, as well as the importance of the first in relation to the audience’s response.</em></p> Martha Judith Soto Flores Jaime Miguel Jiménez Cuanalo Fabiola Laurent Castañeda Copyright (c) 2024 Martha Judith Soto Flores, Jaime Miguel Jiménez Cuanalo, Fabiola Laurent Castañeda 2024-05-23 2024-05-23 7 2 e334 e334 10.37636/recit.v7n2e334 Design, construction and launch of experimental rocket: Tetris <p><em>Since the launch of Sputnik in the 1950s, scale rockets began to be used around the world so that people interested in the space sector had access both in terms of cost, safety and manufacturing. At the facilities of the Autonomous University of Baja California (UABC), a project to design, build and launch the experimental rocket called Tetris was developed. For its design, the Openrocket Software was used, and its components are: the warhead, fuselage, 3 trapezoidal fins, a parachute attached to the rocket structure and the warhead, the type I-J engines and a CanSat-type satellite with parachutes as Useful load. Tetris was built with fiberglass material in the Aerospace Engineering laboratories of FCITEC-UABC. Two launches were successfully carried out at the Laguna Salada facilities located in the state of Baja California, one carrying a can with stones as a weight as a payload and the other launch containing a CanSat. The maximum height reached by the rocket was 595.8 m a.s.l. (meters above sea level) in a time of 10 s, from an initial platform placed at 16 m a.s.l. The main interest in doing these projects lies in manipulating new materials, innovating the techniques used in manufacturing and, above all, acquiring experience to in the future begin the space age in Mexico as it was in the 60s and 70s.</em></p> Liliana Lucero Vargas Oseguera Diana Gabriela Bejarano Toloza Antonio Gómez Roa Oscar Adrián Morales Contreras Oscar Abraham Solano Santos Copyright (c) 2024 Liliana Lucero Vargas Oseguera, Diana Gabriela Bejarano Toloza, Antonio Gómez Roa, Oscar Adrián Morales Contreras, Oscar Abraham Solano Santos 2024-06-11 2024-06-11 7 2 e344 e344 10.37636/recit.v7n2e344
