Education that is able to produce good citizens is education that is able to develop student potential, so that they are able to face the life problems they face. The use of learning resources and learning methods that are less varied and monotonous can cause boredom in students because they are not directly involved in the teaching and learning process, as a result the learning material is not fully accepted by students, in carrying out the objectives of social studies there are still some obstacles in school, namely less active students in receiving social studies learning, as well as not optimally utilized models or media and lack of adequate facilities and infrastructure. The problems above can be overcome by the need for teacher creativity in the use of learning methods, models and resources to support the learning process. The purpose of this study was to determine the effectiveness of social studies learning using the class VII F rotating wheel of SMP Islam Manba'ul Ulum Jepara.

Pendidikan yang mampu menghasilkan warga negara yang baik ialah pendidikan yang mampu  mengembangkan  potensi peserta didik, sehingga mampu menghadapi masalah kehidupan yang dihadapinya.

Medicina, cuerpo, mente y disidencia
Authors: Rodríguez Allen Ana
Published: February 2022

Este artículo aborda las estrategias que las personas utilizan para buscar ayuda con sus dolencias. Está centrado en una de las opciones de sanación existentes en Costa Rica, que la OMS clasifica bajo terapias que integran cuerpo y mente, como la meditación o la hipnosis, y ubicadas al margen de la medicina convencional. Se recurre a obras de pensadores que tienen en común el estudio de la mente, el cuerpo y la medicina; todos, desde sus diferentes campos del saber, plantean pautas de actuación para desmontar la falsa dicotomía mente-cuerpo. Además, muestra que la coherencia entre ambas dimensiones produce salud, ya que las contradicciones en la vida afectiva generan enfermedades. Este escrito no incluye discusiones pormenorizadas de las categorías filosóficas expresadas por sus autores, basta, para nuestro propósito, incluir lo más notable de su pensamiento, no lo dicho con exactitud, sino lo sugerido y provocado en otros respecto de la mente, las percepciones, el yo o la conciencia. Estas reflexiones son un llamado a abrir la mente a nuevas formas de conocimiento, que nos inviten a romper con el dogmatismo y el espejismo de la ciencia médica convencional, que no es más que otra creencia. Aunque algunos textos citados puedan resultar sorprendentes para ciertos lectores, no se trata de adherirse a ninguna corriente, sino de buscar líneas de acción que permitan mantener una condición saludable en todos los ámbitos de la vida.

Stress Method for Pre-Sowing Stimulation of Seeds and Determination of Their Bioenergy Capacity by Calorimetry
Authors: Vasylenkov Viktor , Gudzenko Maxim
Published: February 2022

Introduction. To date, many different devices and methods have been developed for pre-sowing stimulation of seeds in order to increase yields and to maximize the seed bioenergy capacity.Problem Statement. However, the conventional methods for pre-sowing stimulation of seeds with subsequent determination of germination require a wide range of equipment and consumables plus long research time. Developing new methods of pre-sowing treatment and the development of new methods for determining the bioenergycapacity of sowing material is a promising field of research.Purpose. The purpose of this research is to study the stress method for pre-sowing stimulation of seeds and determination of its bioenergy capacity by the calorimetry method.Materials and Methods. To determine the bioenergy capacity of seed material, two batches of Myronivska-808 variety wheat seeds are taken, one of which is subjected to a stress in the form of impact on a rigid surface. The bioenergy capacity of the seed has been determined with the use of the calorimetric device B-08 M, according to DSTU ISO 1928:2006.Results. It has been shown that the bioenergy capacity before and after impact is 10842 kJ/kg and 12649 kJ/kg, respectively, the difference between them is 1807 kJ/kg. This indicates that as a result of the stress treatment of the seeds, their bioenergy capacity increases by 14.3%. At the same time, no seed damages caused by falling of the seed mass from a height of 3 m on a motionless surface have been found.Conclusions. An increase in the bioenergy capacity of seeds after impact by 14—15% indicates that the stress method of pre-sowing stimulation is rather effective. The use of calorimetry methods may be recommended as a way to control the quality of the stress method of pre-sowing stimulation of seed material.

Вступ. Пріоритетними напрямами розвитку науки є фундаментальні наукові дослідження з найбільш важливих проблем соціуму й природи, що забезпечує конкурентоспроможність України у світі та сталий розвиток суспільства й держави.Проблематика. Попри чисельні загрози територіальної цілісності, економічної, екологічної безпеки держави, глобальних проблем, пов’язаних зі зміною клімату, воєнними конфліктами, поширенням COVID-19 тощо, вітчизняна наука на достойному рівні відповідає на зазначені виклики. Серед здобутків української науки можна назвати Енциклопедію міжнародного права, яка є єдиним на пострадянському просторі виданням такого рівня й обсягу та другою в світі після енциклопедії Макса Планка (Max Planck Encyclopedia of Public International Law).Мета. Проаналізувати висвітлення таких категорій як сталий розвиток, екологія, інновації та безпека на сторінках Енциклопедії міжнародного права.Матеріали й методи. Застосовано формально-юридичний метод аналізу текстів нормативно-правових актів, а також статистичні методи структурування та порівняльного аналізу актів законодавства. Також використано загальнонаукові методи пізнання — системний і структурний підходи, аналіз і синтез, індукцію й дедукцію.Результати. Екстенсивне економічне зростання призводить до погіршення екологічної ситуації та виснаження ресурсів, що, в свою чергу, вимагає все більш інтенсивних — (технологічних) методів видобутку, які є ще небезпечнішими для довкілля, або екстенсивних підходів — охоплення нових територій, витіснення конкурентів. Така ситуація на разі становить загрозу національній територіальній, екологічній та економічній безпеці.Висновки. Дослідження таких понять як сталий розвиток, екологія, інновації та безпека на сторінках Енциклопедії міжнародного права виявило міжнародну тенденцію сприймати їх не як окремі категорії, а у взаємозв’язку та взаємозалежності.
Procesos de educación informal en los talleres artesanales de los maestros carroceros del Carnaval Multicolor de la Frontera (Ipiales)
Authors: Verdugo Cabrera Ángela del Mar
Published: February 2022

El presente artículo es producto de una investigación realizada en el marco de la Maestría en Educación, en la línea de Ciencias Sociales, de la Universidad Nacional de Colombia, la cual tuvo como propósito indagar otras formas de educación no convencionales desde el saber artesanal en el marco de lo festivo y carnavalero. Resulta imprescindible revisar desde una mirada crítica las diferentes características que identifican a la educación formal: la escuela. El objetivo de este estudio, de corte cualitativo con enfoque etnográfico, fue rastrear los procesos educativos informales creados en el taller de trabajo de los artesanos carroceros del Carnaval Multicolor de la Frontera de la ciudad de Ipiales, Nariño.

El estudio se acerca a cinco artesanos que inscribieron su carroza para participar en el carnaval del año 2019. La etnografía, por su parte, acude a tres elementos conceptuales claves para entender dichas perspectivas educativas alternas a la escuela: 1) la educación informal, 2) la teoría del caos y 3) el sistema de objetos y de acciones propuesto por Santos (2000).

Así pues, desde el quehacer etnográfico, se identifican aspectos educativos sugestivos como: la estrecha relación entre educación artesanal y familia, la importancia del taller de trabajo como lugar creativo y estimulante, y el caos como elemento inherente a la producción y aprendizaje artesanal de los maestros carroceros.

ADVANCED GRAM-SCHMIDT METHOD FOR RADAR SIGNAL PROCESSING
Authors: Piza D. M. , Romanenko S. N.
Published: February 2022

Context. When protecting radar stations from active noise interference acting along the side lobes of the antenna directional pattern, spatial filtering of signals is used, which is realized by using antennas that are spaced apart in space. In this case, the difference in the directions of reception of the useful signal and the interference makes it possible to form the optimal value of the weighting coefficients of the adaptive spatial filters to suppress the interference. However, if the interfering source moves into the main beam region, then the spatial differences between the wanted signal and the interference are reduced. This leads to significant distortion of the main antenna radiation pattern. As a result, the accuracy of measuring the angular coordinates deteriorates, as well as the sensitivity of the radar receiver. The article proposes a structural-parametric method for adapting a spatial filter, which ensures effective operation of the radar when exposed to the active noise interference both from the direction of the side lobes and from the direction of the main beam.

Goal. Improving the efficiency of the radar when the active noise interference source is shifted from the direction to the side lobes to the direction of the main beam.

Method. The proposed method makes it possible, due to the structural adaptation of the multichannel spatial filter, to exclude the distortion of the main beam of the radiation pattern of the radar antenna and to ensure its operation under conditions of possible interference from the main beam. Structural adaptation of the spatial filter is realized by the current analysis of the weighting coefficients of the compensation blocks.

Results. The structural diagram of the multichannel spatial filter by the Gram-Schmidt method with structural-parametric adaptation, as well as the structural diagram of the compensation block, has been improved. As a result of the simulation, the possibility of eliminating distortions of the radiation pattern of the main antenna of the radar in conditions of the possible impact of the active noise interference along the main beam of the radiation pattern of the radar has been confirmed.

Conclusions. The scientific novelty of the work consists in the improvement of the signal-processing algorithm at spatial filtering both when exposed to the active noise interference from the direction of the side lobes, and when the interference source is shifted to the direction of the main beam of radar. The practical novelty of the work lies in the development of a structural diagram and a mathematical model of an improved spatial filter with structural-parametric adaptation.

RESUMO Desde a implementação de um sistema de câmbio flutuante pelas autoridades econômicas brasileiras em meados de 1999, a trajetória da taxa de câmbio real tem sido caracterizada por extrema volatilidade, inerente a esse sistema. O mercado financeiro brasileiro, no entanto, tem a vantagem de possuir um mercado de derivativos razoavelmente líquido que pode contribuir para um ‘relacionamento’ menos turbulento com um regime de câmbio flutuante. No entanto, quaisquer possíveis benefícios desse mercado para a economia brasileira exigiriam: o uso rotineiro de derivativos financeiros por agentes econômicos em sua gestão de negócios, a eliminação de qualquer restrição ao acesso a mercados de derivativos por investidores estrangeiros e o aprimoramento dos procedimentos de supervisão e regulamentação. mecanismos.

Published: February 2022

Resumo As produções escritas de estudantes podem ser objeto de análise com vista à investigação e ao ensino. Neste trabalho, um dos poucos sobre erros e números complexos, analisam-se as produções, elaboradas por estudantes do ensino superior, para uma tarefa de demonstração de um caso particular da identidade do paralelogramo. Num trabalho que pode dar pistas para a prática letiva de professores do ensino secundário e do ensino superior, procura-se classificar os esquemas de demonstração nessas produções, identificar os erros neles cometidos e relacionar estas duas vertentes de análise. A natureza da investigação é qualitativa, recorrendo à análise de conteúdo empregando, por um lado, critérios prévios de categorizações de esquemas de demonstração e, por outro, critérios novos de categorizações de erros. Constatou-se que os estudantes utilizaram, principalmente, esquemas de demonstração de convicção externa, incluídos numa subcategoria nova designada por não válidos no universo, e esquemas de demonstração dedutivos, incluídos num nível novo que se caracteriza por discernimento incipiente da compreensão da tarefa, do contexto matemático, de hipóteses e tese, e dos conhecimentos prévios a mobilizar. Os erros dominantes nas produções estão relacionados à compreensão dos conceitos de linearidade de uma função e de módulo de um número complexo, apresentando-se possíveis explicações para os mesmos. Apesar de não se identificar uma relação propriamente significativa entre os esquemas de demonstração produzidos pelos estudantes e os erros cometidos, obteve-se material para construção e discussão de questões conceituais no âmbito do tópico números complexos.
Computation of the repairability index of short buildings with rocking connections
Authors: Bavandi Mohammad , Moghadam Abdolreza S , Mansoori Mohammad Reza , Aziminejad Armin
Published: February 2022

Recently developed steel self-centring moment-resisting frames have been analytically and experimentally validated as having the potential to eliminate structural damage under a design basis earthquake and restore their original vertical position following a major earthquake. In this study, the repairability index of post-tensioned self-centring frame for near-field earthquake has been developed. According to the six models of the studied building, a building that can be repaired, the maximum rotation in its connection after the earthquake does not exceed the rotation of the immediate occupancy performance. Based on this, the output data of incremental dynamic analysis analyses were drawn according to the connection of relative rotation and spectral acceleration. According to the predicted performance levels for each acceleration level, the value of the connection opening is divided by the opening of the design-basis earthquake level. The resulting curve shows the repairability index according to spectral acceleration, which if less than one, the repairability target is achieved. To evaluate the damage, the angle failure probability of post-tensioned self-centring frame for near-field earthquake has been developed. This index equation is determined according to the fragility curve and the intensity of damage in each building.
Unprecedented liquefaction flow of gentle slopes containing non-plastic fines
Authors: Kokusho Takaji , Hazarika Hemanta , Ishizawa Tomohiro , Ishibashi Shin-ichiro , Ogo Katsuya
Published: February 2022

In two recent earthquakes in Hokkaido, Japan, liquefied sand unusually flowed underground in very gentle man-made fill slopes, creating large ground surface depressions. In both cases, a significant amount of non-plastic fines was present in the loose fine sands. When tested in undrained triaxial tests, these sands were found far more contractive and easier to flow than the sand of the same density without fines. This strongly suggested that the high fines content was the major cause of the strange flow failures because it made the sand flowable on the contractive side of the steady-state line. Another series of cyclic torsional simple shear tests on contractive sands with fines under initial shear stress indicated that the flow failure can initiate even in a gentle slope. This is when the effective stress path comes across a straight yield line drawn from the origin on the τ − σc′ diagram uniquely defined irrespective of stress paths. A scenario to replicate the unusual flow failures was developed based on the field study and test results.

The influence of different interlayers on the microstructure, microhardness, friction and wear properties and electrochemical behavior of the films was investigated. The morphological results show that the porosity of DLC films was reduced and the particles were refined after the introduction of a double interlayer. Raman and X-ray photoelectron spectroscopy results confirm that the amorphous characteristics of DLC films containing nickel and copper interlayers were enhanced, and the content of sp3 carbon in the films was increased. Besides, an optimal microhardness of 210.67 HV was achieved due to the high sp3 carbon content of the double nickel/copper–DLC film. Meanwhile, the nickel/copper–DLC film possessed excellent wear resistance, which benefits from the synergistic effect of the copper and nickel interlayer. Nickel as the supporting layer and copper as the lubricating layer alleviated the wear and friction of the film. Simultaneously, the deposition of a double interlayer increased the density of the film, which further prevented the invasion of corrosion ions, so the film had superior electrochemical properties.

In the nature, larvae living in watercourses are exposed to a complex system of environmental influences. It is known that different watercourse types (creeks, brooks, streams, little rivers and medial rivers) provide different conditions for larval development (water depth, flow rate, temperature, oxygen content, substrate type, nutrient supply, etc.). These conditions can vary significantly between watercourse types, but be very similar within types. In this work, we examined the body sizes and wing morphometric characteristics of males of Calopteryx splendens reared from different watercourse types (brook, stream, creek, little river, medial river). Although there were no significant differences in body size among watercourse types, we found significant differences in the wing features. We found the most differences between the individuals reared from streams and creeks and between the individuals reared from stream and medial river. Our results show that the individuals reared from different watercourse types were clearly separated on the two wings. The results also suggest that there are significant differences in the number and pattern of allometric features on the wings of individuals reared from different watercourse types.

Maín Ximénez es el primer seudónimo del poeta colombiano Porfirio Barba Jacob. Mediante un recorrido biográfico por su infancia y primera juventud, rastreo los orígenes de Maín desde la correspondencia, escritos autobiográficos y archivos de la época. Indago en las publicaciones en las que aparece y en el tránsito del plano real al literario para entender el sentido y la trascendencia del nombre. Atiendo a su nacimiento poniendo atención en la forma como Maín migra al poema para entrañar su proyecto poético, gestado desde un ambiente rural agreste con la creación de Maín en el centro de sus preocupaciones escriturales.

Antecedentes: los tratamientos con base en medicamentos contra la COVID-19 no han sido aprobados hasta la actualidad. La forma más efectiva de enfrentar este problema de salud pública es la prevención con una adecuada alimentación, medidas de higiene y protección. Los alimentos han sido históricamente utilizados por la población para mejorar su nutrición y complementar el tratamiento o prevención de enfermedades. Se conocen los diversos compuestos bioactivos de algunos alimentos, que en estudios experimentales demostraron su acción antiviral e inmunomoduladora. Objetivo: identificar los compuestos bioactivos o preparados de alimentos con potencial efecto inmunomodulador, inmunoestimulante y antiviral contra el coronavirus. Materiales y métodos: se realizó una búsqueda en Google Scholar, Scopus y en la Biblioteca Virtual de Salud en Bases de datos de Medicina Tradicional, Complementaria e Integrativa utilizando los términos food, immunomodulatory, immunostimulatory y anti­viral en cuatro búsquedas sucesivas. Resultados: se obtuvieron 93 artículos y se identificó mayor evidencia sobre el efecto antiviral e inmunológico contra el coronavirus en nueve alimentos: Allium sativum, Cinnamomum zeylanicum, Citrus sinensis, Zingiber officinale, Vitis vinífera, Allium cepa, Curcuma longa, Punica granatum y Sambucus nigra. Los cuatro primeros mostraron actividad contra el SARS-CoV-2. Conclusiones: se evidenció el efecto inmunológico y antiviral contra el coronavirus de nueve alimentos; sin embargo, son estudios in silico e in vitro, por ello se requiere mayor investigación preclínica y clínica que lo confirmen.

La contaminación por metales pesados es actualmente uno de los problemas ambientales más serios y complejos de tratar. Las pilas de lixiviación de las industrias mineras se caracterizan por su elevado contenido en metales disueltos, además de ser considerado un hábitat propicio para el desarrollo de microorganismos resistentes. Entre ellos, aquellos microorganismos autóctonos con adaptaciones fisiológicas que le permiten tolerar elevadas concentraciones de metales pesados los cuales son considerados como candidatos para procesos de biorremediación. Por esto, el objetivo de este estudio fue aislar y seleccionar cepas de hongos filamentosos con potencialidad para la remoción de metales pesados. Se tomaron muestras de pilas de lixiviación de la Mina Hualilán en la provincia de San Juan (Argentina). El aislamiento de los hongos filamentosos se llevó a cabo en medio Sabouraud-glucosa-agar con antibióticos y se identificaron por técnicas de biología molecular (amplificación y secuenciación del fragmento ADNr 18S y 26S, ITS1, ADNr 5.8S e ITS2). Se estudió la tolerancia a Cu (II) y Pb (II) en placas con medio PDA con concentraciones entre 25 y 800 ppm de cada metal. Las condiciones de incubación fueron a 28ºC durante un período de total desarrollo de los hongos comparado con una placa control (sin metal), midiendo diámetros de crecimiento. Se realizó un análisis estadístico haciendo un análisis de varianza y prueba de comparación de promedios Duncan, con el programa estadístico Anova multifactorial bajo un diseño experimental completamente al azar con arreglo factorial 2x6x1, una caja Petri como unidad experimental, y tres repeticiones. Como resultado se aislaron tres cepas: Penicillium simplicissimum, Fusarium sp y Penicillium funiculosum. Los hongos identificados presentan tolerancias a distintas concentraciones de soluciones de los metales, donde la cepa más tolerante fue Penicillium simplicissimum.

Published: February 2022

Acute toxicity of copper, cadmium individually and in combinations of Cu + Cd were studied in carp, Labeorohitaas a function of time. Mortality of fish was dependent on dose of metal exposures and exposure period. The behavioural changes of L. rohitawere found to be different when exposed to Cu and Cd individually and in combinations. It was more pronounced in test animals exposed to equitoxic levels of Cu + Cd followed by individual exposures of Cu and Cd, while it was completely absent in the control fish. The 96 hr median lethal concentration of copper, cadmium and combination of both in L. rohitawas 0.42, 0.78 and 0.39 ppm respectively. Similar trend was observed in 24, 48 and 72 hrs also. It manifests that Cu + Cd combination was more toxic than any one of the single metal solutions tested
