La traza y calzadas de México Tenochtitlan y Tlatelolco
Authors: Merlo Eduardo
Published: September 2022

La gran ciudad de Tenochtitlan y Tlatelolco se situaba dentro de un enorme lago que cubría toda una cuenca en el Altiplano Central Mexicano. Fue edificada a base de plataformas artificiales soportadas en troncos de ciertos árboles locales llamados ahuejotes, los cuales se encajaron en el fondo lacustre y con ello propiciaron el crecimiento urbano con esa peculiar e inusual técnica que sus habitantes aprendieron de los pueblos del sur de la cuenca. La disposición de las calles y manzanas alineadas de oriente a poniente y de norte a sur, permitieron que las calles que realmente eran canales, se limpiaran y sanearan gracias al intenso oleaje. Muy importante fue establecer los medios de comunicación con las orillas del lago, esto es, con tierra firme. Al efecto construyeron en la misma forma que las extensas plataformas, tres grandes calzadas que tenían “cortaduras” es decir partes abiertas para permitir la comunicación lacustre, amén de otras vías de acceso.

Antropología Americana se complace en presentar en este número un conjunto de investigaciones referidas al tema de la Conquista. Si bien se refieren a un hecho ocurrido hace quinientos años, no hay que olvidar que ese acontecimiento cambió el rumbo de la historia y marcó las pautas de un proceso global de distinciones y desigualdades que siguen prevaleciendo hasta nuestros días. El impacto de la Conquista sigue marcando las distinciones y clasificaciones sociales en América Latina y el Caribe, pautas que se sustentan en la racialización de la diversidad cultural y en prácticas de exclusión basadas en criterios de “raza”, nacionalidad, lugar de origen y género.

Organizaciones, cultura religiosa e identidad en los Altos de Chiapas, un estudio con perspectiva de género
Authors: Castellanos Verónica
Published: September 2022

The aim of the research presented was to analyze the religious culture and the identity of three organizations as a key element for development, highlighting the role of women in management. Fieldwork was conducted in three organizations of Chiapas with different religious ideology: the first "The Boarding School" Catholic, the second "Eagles" - Christian and the third "La Alpujarra" - Islamic. We use a methodological strategy in which we visualize the phenomenon as a "totality" to understand the multidimensionality and interaction between the dimensions studied. Dimensions: 1) organization; 2) management; 3) religious culture; and 4) identity. Finally, we see that the organization is the space where different forms of management are developed and where identity is expressed through activities, attitudes and relationships of the actors, and which is closely matched by the religious culture that have their members and where women play a key role in guiding and replicating their religious values and culture.

Una tesis sobre pedagogía de lo cotidiano
Authors: Vilchis Jardón Jair Alejandro
Published: September 2022

La pedagogía de lo cotidiano ha sido a partir de su creación, difusión e interpretación por los distintos seguidores que la han abordado, un movimiento pedagógico que, si bien, más allá de quedar en una propuesta educativa que se estanca como algunas con el paso del tiempo y que van perdiendo su capacidad de usarse, moldearse y ponerse en práctica ante las nuevas necesidades que en el siglo XXI surgen, se va actualizando por su capacidad de abordar la realidad cotidiana que viven tanto los estudiantes como las personas que habitan el mundo.

De lo anterior podemos encontrar evidencias en los distintos trabajos y reflexiones de quienes seguimos el pensamiento pedagógico primeriano. Por lo tanto, la intención de este trabajo es analizar una –de tantas– tesis donde esta pedagogía se puso en práctica gracias a su capacidad de estar en el movimiento de frontera, es decir, en el conocimiento y/o saber que se encuentra en constante actualización.

Por lo anterior, cabe resaltar que el análisis que se realiza es a partir del Método Racional de Pensamiento (MRP) —contenido en la obra de Luis Eduardo Primero Rivas—, donde a partir de la descripción, interpretación y valoración se desglosaran las ideas principales del trabajo que el licenciado Cesar Augusto Castro Rodríguez ha hecho en la universidad de La Gran Colombia, situada en Colombia, donde ha detectado que la formación de los estudiantes de la licenciatura en ciencias sociales de ésta universidad, se encuentra alejada de la actualización, esto debido a la enseñanza a partir de modelos, ideas, tradiciones y reflexiones surgidas de pedagogías y métodos de enseñanza del siglo pasado.

Background: Female reproductive organs are more susceptible to the risk of increased cadmium accumulation. Ivermectin is a known therapeutic drug in general medicine, while Allium cepa possesses antioxidant ability. This study investigated the effects of Ivermectin and Allium cepa on cadmium-induced ovarian and uterine damage in adult Wistar rats.
Methodology: Twenty-Eight adult female Wistar rats were randomly divided into six groups. Group (A); control group, Group (B); treated with 1.2 mg/kg b.w of Ivermectin, Group (C); treated with 1.2 mg/kg BW of Ivermectin and 2 mg/kg BW Cadmium respectively, Group (D); treated with 2 mg/kg BW Cadmium, Group (E); treated with 2 mg/kg BW Cadmium and 1.5 ml Allium cepa respectively, and Group (F); treated with 1.5 ml Allium cepa. The administration was done orogastrically and daily for four weeks. Animals were euthanized by cervical dislocation twenty- four hours after the last administration, Ovary and Uterus excised following abdominal incision, tissues for histological observation fixed in Bouins’ fluid for H/E stain, Masson trichrome, fuelgen stain, and toluidine blue stain respectively. Samples for enzymes assay were homogenized in 5% sucrose solution for lipid peroxidation using; MDA and the antioxidant enzymes using SOD and CAT.
Result: Cadmium treatment exerted oxidative stress, elevated the enzyme markers for oxidative damage in the ovary and uterus, and increased lipid peroxidation leading to cell membrane damage. Histological alterations, degeneration of ovarian follicles, and loss of endometrial lining characterized the animals exposed to cadmium. Allium cepa increased the antioxidant enzymes; SOD and CAT while lowering the MDA activities in Cadmium-induced oxidative stress. Histological integrity of the ovary and uterus was maintained; follicular development was evident at various stages, and the endometrial lining integrity was maintained.
Conclusion: This study demonstrated the protective role of Allium cepa and Ivermectin against cadmium toxicity on the reproductive organs in female adult Wistar rats

Analysis of the Length of Use of Kumbung on the Productivity of Straw Mushrooms (Volvariella volvaceae)
Abstract
The environment, the quality of the media, the inoculation technique of seedlings and the quality of seedlings are some of the factors that affect the productivity of the straw mushrooms. Environmental conditions are one of the main factors. Ideal environmental conditions must be maintained by straw mushroom farmers, the production of straw mushrooms remains as stable as possible. Room temperature is a factor that must be considered to maintain the growth and development of straw mushrooms. Room temperature can be ideal if the condition of the kumbung and the quality of the media are maintained. This researcher aims to analyze the productivity of the kumbung during the first year of production. Productivity is measured through the length of production and the mass of the acquired straw mushroom. The average production of straw mushrooms in each month is 103.7 Kg with an average production duration of 30 days.  The correlation between the amount of production and the duration of harvest is positively correlated with the calculated R value of 0.978>R table 0.4575.  Based on field studies and data analysis, the amount of production is positively correlated with the length of harvest and mushroom production and will decrease with age. The decline in productivity is due to the decline in the quality of the growing media. Contaminants and the difficulty of engineering a continuous climate are other factors that influence the decrease in the number and duration of straw mushroom production.

Objective: To identify the indications for physiotherapy and to evaluate physiotherapy practices in patients with COVID-19 admitted to the ICU (on mechanical ventilation) or to the ward (spontaneously breathing). Methods: An online, 50-item survey was completed by physiotherapists who had been treating hospitalized patients with COVID-19 in Brazil. Results: Of the 644 physiotherapists who initiated the survey, 488 (76%) completed it. The main reasons for indications for physiotherapy in both settings reported as "very frequently" and "frequently" both in the ICU and the ward by most respondents were oxygenation improvement (> 95%) and prevention of general complications (> 83%). Physical deconditioning was considered an infrequent indication. When compared with mobilization strategies, the use of respiratory interventions showed great variability in both work settings, and techniques considered effective were underutilized. The most frequently used respiratory techniques in the ICU were positioning (86%), alveolar recruitment (73%), and hard/brief expiratory rib cage compression (46%), whereas those in the ward were active prone positioning (90%), breathing exercises (88%), and directed/assisted cough (75%). The mobilization interventions reported by more than 75% of the respondents were sitting on the edge of the bed, active and resistive range of motion exercises, standing, ambulation, and stepping in place. Conclusions: The least common reason for indications for physiotherapy was avoidance of deconditioning, whereas oxygenation improvement was the most frequent one. Great variability in respiratory interventions was observed when compared with mobilization therapies, and there is a clear need to standardize respiratory physiotherapy treatment for hospitalized patients with COVID-19.

Rancang Bangun dan Analisis Akurasi Dinamometer Untuk Kajian Biomekanika Gaya Penari Bapang
Authors: Adri Pamungkas Prasetyo , Agus Sahbana Muhammad , Finahari Nurida
Published: September 2022

Biomechanics is the study of internal and external forces acting on the body of living things and the effects of these forces. The study of the motion of living things is carried out by applying theories and laws of motion. The forces acting on the human body organ systems in biomechanics include gravitational force, body reaction force and muscle force. These forces can be measured using a dynamometer. This study aims to design a load cell sensor-based dynamometer which is used as a mass sensor, applied to the design, then analyzed its accuracy for the study of the biomechanics of Bapang dancers. The design is based on the availability of research funds but refers to the Mettler Toledo weighing principle, where the floor scale is designed as a measuring base for the dancers to perform their dances. The area of ​​this measuring base is predefined as 1.25 x 1.25 m. This has reduced the accuracy of the design results considering the ideal area for free dancing is 3 x 3 m. The design results have worked well and can record changes in the load during changes in dancer movements. The measured reading accuracy value reaches 98.36% but still includes measurement errors due to differences in the place and time of the calibration measurement, and differences in the clothes of the people who are the object of the load. The load reading display captures an average time delay of 0.468 seconds. It is recommended that the drawbacks of this design be corrected by designing a dancer's load measurement system using a load sensor that is shaped like a ballet shoe, but uses a wireless data transfer system so that the dancers can move freely. In addition, the shoe-shaped dynamometer design can definitively separate the load readings for the right and left feet.

Statement of the problem. As a rule, when choosing a method of transporting natural gas to various categories of consumers, several options are considered depending on the mutual distance between the source and the consumer - the construction of a gas pipeline or the creation of an infrastructure for liquefied gases. The competitiveness of liquefied natural gas (LNG) in comparison with natural gas is proposed to be determined within the framework of model gas supply schemes for different ranges of alternative energy supply systems. Results. The results of the calculation according to the developed algorithm based on the Clark-Wright method allow us to conclude on the least expensive layout option for automotive cryogenic tanks and cryogenic storage facilities for consumers, determine the number of working hours per month for truck tanks, and also determine the optimal number of cryogenic tanks to deliver the required volume LNG and the number of cryogenic storage tanks at consumers. Conclusions. The proposed economic and mathematical model can be used to substantiate the competitiveness of the use of natural and liquefied natural gases to meet the various needs of consumers. The proposed mathematical calculation model makes it possible to identify the efficiency of each of the energy carriers, as well as to identify the main criteria for choosing the most efficient energy carrier for specific conditions of use.

The development of a new composite finishing building material based on a gypsum binder filled with wood filings is conditioned by the need to find ways to solve the problem of reducing the cost of finishing materials while maintaining their environmental friendliness and other operational parameters. Results. The article carried out the mathematical planning of an experiment on the selection of the optimal composition of a new building finishing material based on a gypsum binder filled with wood filings. Response equations are obtained for the following characteristics of the material: gypsum binder consumption per unit volume, density, thermal conductivity coefficient, transverse bending strength and compression. Conclusions. Based on the analysis of the level of perception of the characteristics of the material (application of an expert assessment method), the experimentally obtained results of the regression assessment allow one to determine the composition of a new finishing material based on the perception of gypsum binder by wood filings.

Постановка задачи. Исследуется проблема формования гипсовой смеси (шлама), являющаяся важнейшей технологической составляющей процесса изготовления листового гипсокартона. Решение данной задачи проводится в рамках реологической модели изотермического, стационарного течения несжимаемой бингамовской среды в плоском канале между параллельными плоскостями в условиях скачкообразного изменения градиента давления. В предположении одновременного присутствия сдвиговой (вязкой) и пластической (квазитвердой) областей течения исследование напряженно-деформированного состояния среды проводится отдельно для каждой из составляющих. Результаты и выводы. Из условия равенства по величине интенсивности напряжения в сдвиговой области и предельного напряжения в пластической зоне определена координата границы раздела указанных областей. Определен перепад давления, при котором бингамовская среда ведет себя как пластическое тело, а при превышении предельного значения, наряду с пластической областью, появляется зона вязкого течения. Получены аналитические выражения для скорости течения и касательных напряжений, возникающих в процессе формования гипсовой смеси в зависимости от толщины деформированного слоя.

Statement of the problem. The paper investigates the problem of the formation of gypsum mixture (sludge), which is the most important technological component of the manufacturing process of sheet drywall. The solution is carried out within the framework of a rheological model of the isothermal, stationary flow of an incompressible Bingham medium in a flat channel between parallel planes under conditions of an abrupt change in the pressure gradient. Assuming the simultaneous presence of shear (viscous) and plastic (quasi-solid) flow regions, the stress-strain state of the medium is studied separately for each of them. From the condition of equality in magnitude of the intensity of stress in the shear and tangential - in the plastic regions, the coordinate of the interface of these regions is determined. A pressure drop is determined at which the Bingham medium behaves like a plastic body, and when its limit value is exceeded, a viscous flow zone appears along with the plastic region. Results and Conclusions. Analytical expressions are obtained for the flow velocity and tangential stresses arising during the molding of the gypsum mixture depending on the thickness of the deformed layer.

A REVIEW ON THE FREQUENCY RESTORATION IN A TWO AREA POWER SYSTEM
Authors: Ashok Maruvada  , Ramana Pilla
Published: September 2022

In the process of achieving frequency restoration in multi area multi source, we came across several problems. First one is to place a controller to maintain and tune the gain parameters of different generation units to get the optimal response by proper optimization technique to simulate the environment for finding the optimal values. Here we are analyzing the Hybrid Differential Evolution Pattern Search based Fuzzy PID controller for AGC of multi area power system. In this work, a two area six-unit hydro, thermal, wind and diesel system were examined. Area-1 consists of hydro + thermal +wind and area-2 consist of hydro +thermal + diesel which is interlinked with a tie-line. The future scope will be on simulation results which validate the present work of hybrid pattern search differential evolution (HPS-DE) with other techniques in terms of frequency deviation, tie-line power deviation.

Published: September 2022

Introduction: This article proposes a methodology for assessing the efficiency of decision-making for the use of near-Earth space sensing tools based on the software implementation of a simulation model for obtaining measurements on space objects in the middle and far near-Earth space zone by space exploration tools with the use of a software and hardware complex for collecting information. Setting the task: to develop an assessment methodology based on a simulation model for detecting space objects in their orbits by ground-based space observation means, taking into account various options for stochastic construction of space object trajectories and operating conditions, technical condition, geographical location and number of optical observation means. Results: a methodology and a simulation model of a software and hardware complex for collecting information about the space situation has been developed, taking into account various options for building orbits of observed space objects and allowing dynamically developing the simulated space situation, as well as modeling changes in the state of observation tools, taking into account changes in their technical condition, weather conditions, daily cycle and geographical location. Practical significance: the proposed methodology and simulation model allows calculating the optimal number of necessary means of observing outer space and their preferred locations based on an assessment of the effectiveness of their functioning during a dynamic change in the states of their functioning. Discussion: the novelty of the proposed task statement is that the structure of the developed methodology and simulation model allows you to take into account various factors affecting the means of observation and build probabilistic estimates of the effectiveness of their functioning based on a dynamic change in the states of functioning of the means of observation.
