Приведены результаты исследований кинетики испарения воды при сушке смеси вода–белок при 60°С в изотермических условиях. Смесь готовили из дистиллированной воды, предварительно доведенной до кипения при атмосферном давлении, которую заливали в две чашки Петри по 20 мл в каждую, и яичного белка, добавленного в количестве 0,2 и 0,6 мл соответственно. Чашки Петри помещали в сушильный шкаф Memmert, оснащенный принудительной конвекцией и устройством контроля температуры. Навеску с чашкой Петри взвешивали через каждые 5 мин на аналитических весах Discovery. Установлено, что увеличение количества белка снижает скорость испарения воды в периоде постоянной скорости сушки, скорость испарения зависит от природы растворенного вещества. По окончании процесса испарения на дне чашки Петри обнаружена полупрозрачная высохшая пленка белка, что свидетельствует о конформационных перестройках белка в процессе убыли влаги и частичном растворении белка в воде в процессе испарения.

The results of studies of the kinetics of evaporation of water during drying of the water–protein mixture at 60°C in isothermal conditions are given. The mixture was prepared from distilled water, pre-boiled at atmospheric pressure, which was poured into two Petri dishes of 20 ml each, and egg white added in an amount of 0,2 and 0,6 ml, respectively. Petri dishes were placed in a Memmert drying Cabinet equipped with forced convection and a temperature control equipment. The overhang with a Petri dish was weighed every 5 min on the analytical scales of Discovery. It was found that an increase in the amount of egg protein reduces the rate of evaporation of water in a period of constant drying rate and the rate of evaporation depends on the nature of the dissolved substance. At the end of the evaporation process, a translucent dried protein film is found at the bottom of the Petri dish, which indicates the conformational rearrangements of the protein in the process of moisture loss and partial dissolution of the protein in the water during evaporation.

The central mediators of the adaptive immune response are T cells. The clonal expansion of T cells required for adaptive immunity results from the innate immune response, which is triggered by the stimulation of Toll-Like Receptors (TLRs). The adaptive immune response can cause autoimmune diseases, and Th17 cells are known to contribute to several autoimmune diseases. Pathogenic Th17 cells are induced by Interleukin 23 (IL-23) and IL-1Β. Resiquimod (a TLR7/8 agonist) significantly enhances IL-23 production by human macrophages, and lipopolysaccharide (a TLR4 agonist) slightly enhances it. Interestingly, IL-23 levels are significantly attenuated after sequential stimulation with lipopolysaccharide and resiquimod, indicating cross-talk between the TLR4 and TLR7/8 signaling pathways. In this review, we discuss the pivotal role of TLRs in triggering innate immunity and inducing adaptive immunity, leading to autoimmune diseases.

We report the case of an 18-year-old patient who consults for a loss of visual acuity in the right eye for 1 year. On clinical examination, visual acuity is 20/100. Eye tone is 12 mmhg. Examination of the anterior segment shows the existence of a cataract made up of whitish opacities corresponding to a congenital cerulean cataract (Figure 1). The treatment consisted of a cataract cure by phacoemulsification with good progress. Cerulean cataract is a rare congenital form of bluish tint, made up of whitish opacities in concentric layers with a radial arrangement at their center. Visual acuity is fairly good in childhood but may deteriorate later. In the literature, the incidence of cataracts in Down’s children ranges from 5% to 50%. In previous studies of congenital or infantile cataract, 3-5 % of cases were associated with Down’s syndrome [1].

Authors: Moshkivskaya V. A.
Published: November 2021

Introduction. The problem of infertility is widely known around the world. According to WHO, 3% of the world's population suffers from infertility. In Russia, the problem of infertility is extremely urgent, the number of couples applying for assisted reproductive technologies is growing every year. However, the number of positive IVF protocols, successful pregnancy outcomes, and the quality of life of children born prematurely is still not high. There are more than 700 factors that affect the outcome of pregnancy, most of which are poorly understood, and research in various fields continues. In addition to the proven physiological factors that affect the outcome of pregnancy, there are a number of poorly understood factors that cause idiopathic infertility.

Materials and Methods. Author's semi-structured interview for a married couple during pregnancy. Male and female version of the interview. Repeated author's interview for a woman in the early postpartum period. Content analysis.

Results. The main results obtained during the interview were analyzed. Such as the subjective assessment of the perception of pregnancy (physical, emotional experiences), the motive of pregnancy, the assessment of one's own parental readiness to raise a child, parental competencies, changes in marital roles, studying the lifestyle before and during pregnancy, contact with one's own parents, behavior during childbirth, primary contact with a newborn child.

Discussion and Conclusions. According to the results of the study, conclusions were obtained indicating the importance of timely provision of psychological assistance to pregnant women as a result of the use of ART. Women who are pregnant with ART are more anxious, less self-oriented, more likely to have obstetric and neonatal complications, difficulties with primary psychological contact with a newborn child, difficulties with breastfeeding.
A new structural model for measuring spatial intelligence
Authors: Chikova O. A. , Zolotavin V. S. , Kamenev R. V. , Maksimova L. A.
Published: November 2021

Introduction. The task of studying the structure and dynamics of spatial thinking of schoolchildren and students is relevant for general and educational psychology and private teaching methods. The research goal of the article is to theoretically substantiate, develop and test a structural model for measuring the spatial intelligence of students and schoolchildren.

Materials and Methods. On the basis of a comparative analysis of the content of the definition of "spatial intelligence" in domestic and foreign educational psychology (I.S. Yakimanskaya, H. Gardner), a structural model and a rapid test for measuring the spatial intelligence of students and schoolchildren have been developed. The Structural Equation Modeling methodology was used to validate the developed express test. The research sample consisted of 688 schoolchildren from Novosibirsk at the age from 10 to 15 years.

Results. The model for measuring the spatial intelligence of students and schoolchildren is developed by correlating the components of spatial intelligence: spatial knowledge, spatial abilities, spatial skills, with the corresponding cognitive processes: perception of space, spatial representation (thinking), spatial imagination. Based on the classification of intelligence tests into three separate categories: spatial perception, spatial visualization, mental rotation from intelligence subtests (R. Amthauer, M.C. Linn, A.C. Petersen, M. Sjölinder), a rapid test was constructed. The reliability (validity) of the express test was confirmed using structural equation modeling by the method of confirmatory factor analysis of models consisting of 15 indicators and one factor (spatial intelligence) or three factors (spatial knowledge, spatial abilities and spatial skills).

Discussion and Conclusions. The theoretical significance of the developed structural model is that it reveals the mechanisms of the natural development of spatial intelligence, depending on the degree of formation of its substructures. The practical significance of the obtained result lies in the development of methodological foundations for screening diagnostics of the spatial intelligence of schoolchildren and is due to the high importance of spatial thinking for solving educational problems.

The pandemic Covid-19 has been changing tourist behavior to visit a tourism destination. This study aims to investigate tourist’ visit intention after Covid-19 pandemic period in Indonesia by addressing the Covid-19 phenomenon, health consciousness and theory planned behavior framework. To answer hypotheses in this study, Confirmatory Factor Analysis-Structure Equation Model is used with quantitative approach. The research model is examined by SEM-PLS, using SmartPLS-3 software to analyze research framework. The results show that Covid-19 perception had not significantly impacted attitude, subjective norm, perceived behavioral control and intention. However, the perception of Covid-19 has a significant impact on non-pharmaceutical intervention, which in turn delivers a significant impact on attitude, subjective norm, perceived behavior control and visit intention. The hypothesis presumes that attitude, subjective norm, and perceived behavior control all have significant impact on intention to visit. In contrast, variable of health consciousness works less impact on intention to visit. This study makes significant contribution to the tourism literature by considering health issue and tourist visit behavior after Covid-19 period in Indonesia. Doi: 10.28991/esj-2021-SPER-15 Full Text: PDF

Ciclos económicos y variables monetarias y financieras en México, 1980-2019: un enfoque de cambio estructural
Authors: Vergara González Reyna , Mejía Reyes Pablo , Díaz Carreño Miguel Angel
Published: November 2021

El objetivo de este documento es analizar la relación entre el ciclo económico y diversas variables monetarias y financieras con el fin de determinar si han sido estables en el tiempo, teniendo en cuenta los efectos de las modificaciones en las condiciones económicas generales, la estrategia específica adoptada de política monetaria en diferentes subperiodos y las condiciones institucionales en que esta se maneja. Para probar la estabilidad de estas relaciones, una vez que se obtienen los indicadores del ciclo mediante los filtros convencionales, se emplea la metodología de cambio estructural de Bai y Perron (1998). Los resultados destacan dos cambios estructurales en la relación entre el indicador del ciclo y las variables de inflación, tasa de interés, tipo de cambio nominal y agregados monetarios nominales, uno a mediados de los años ochenta y el otro a mediados de los noventa.
 
Abstract
 
This paper aims to analyze the relationship between the business cycle and various monetary and financial variables. In particular, the paper seeks to determine whether this relationship has been stable over time, considering the effects of the changes in the general economic conditions, the specific monetary policy strategy adopted in different subperiods, and the institutional framework in which this is managed. To test the stability of these relationships, once the cycle indicators are obtained using conventional filters, the structural change methodology of Bai and Perron (1998) is used. The results highlight two structural changes in the relationship between the cycle indicator and inflation, interest rate, nominal exchange rate, and nominal monetary aggregates, one in the mid-eighties and the other in the middle of the nineties.

Corrupción política, sistema de partidos y criminalidad organizada
Authors: Sansó-Rubert Pascual Daniel
Published: November 2021

El mapa de la corrupción es extenso, tanto a niveles nacionales, como internacionales. La corrupción es un fenómeno universal que se reproduce indistintamente, al igual que la criminalidad organizada, con independencia de la modalidad de gobierno y de sistema político, alcanzando tanto a países ricos, como a subdesarrollados. Ninguna forma de gobierno resulta indemne al desarrollo de las prácticas corruptas. Por ello, este trabajo refleja el esfuerzo por entender cómo incide la corrupción en la esfera política a través del análisis de las fortalezas y debilidades de los sistemas electorales y de los partidos políticos, con el fin de, una vez identificadas las vías de penetración de la criminalidad organizada, implementar estrategias y políticas que posibiliten revertir el acceso de la delincuencia organizada al ámbito político y al ejercicio de Gobierno, con especial intensidad en el espacio local y regional. Cuestión, que se ha convertido en uno de sus principales objetivos estratégicos. Para ello, destacan sobremanera las iniciativas orientadas a la limitación del ejercicio de derechos fundamentales, cobrando especial relevancia en concreto la instauración en los ordenamientos jurídicos de la opción de la prohibición de partidos políticos contrarios al orden constitucional.

Published: November 2021

A mastery in Engineering Science Course is closely related to the physics subjects in schooling which involve problem solving techniques including mathematical skills. Engineering Science Course is considered difficult and complicated that need to be understood since there are many concepts to understand, especially for students who do not take science courses in school. Mastery of a course is closely linked to academic achievement that has a great impact on student achievement. Thus, a study was conducted to identify factors that influence student’s performance in the Engineering Science Course at Politeknik Sultan Mizan Zainal Abidin (PSMZA). A total of 179 respondents from four departments; Department of Civil Engineering (JKA), Department of Electrical Engineering (JKE), Department of Mechanical Engineering (JKM) and Department of Mathematical Science & Computer (JMSK) were involved in this study. The analysis of the study was done using descriptive statistics, T-test and Pearson Correlation using Statistical Package for Social Science (SPSS) version 23. Analysis of the result shows that environment was the main driving force with the mean value of 4.31 being the highest score compared to existing knowledge factors, interests, attitudes, lecturers and peers. T-test analysis also found that there was a significant relationship between attitude and gender differences. Pearson Correlation’s analysis found that the relationship between lecturers and interests was average and significant. While peers, environment and interest were strongly related, but significant. It is hoped that the findings of this study will help to provide an overview of the factors that influence student performance in the Engineering Science Course at PSMZA. This will also help JMSK to take preventive measures and improve all aspects of its efforts to improve student performance in the Engineering Science Course at PSMZA.

Helicobacter sp, bacilo Gram negativo, se encuentra asociado a gastritis, úlcera y cáncer gástrico.La prevalencia mundial de la infección por H. pylori es mayor al 50%, constituyendo un problema de salud pública. Diferentes especies de Helicobacter afectan tanto a animales como seres humanos, pudiendo ser responsables de zoonosis. El proceso de colonización de esta bacteria depende en gran medida de su unión a glicoconjugados presentes en la mucosa gástrica del hospedero. El cerdo representa el modelo animal de elección para el estudio de la infección por esta bacteria. El objetivo del presente trabajo fue analizar el comportamiento del glicoconjugado glucosa/manosa en la mucosa gástrica de cerdos afectados por gastritis producida por Helicobacter sp. Se utilizaron muestras de la región antral del estómago de cerdos mestizos, obtenidas de frigoríficos de Río Cuarto (Argentina). Dichas muestras fueron clasificadas en distintos grupos de estudio de acuerdo al tipo de gastritis y a la presencia y/o ausencia de Helicobacter sp. Las muestras fueron luego sometidas a lectin-histoquímica para la marcación del glicoconjugado glucosa/manosa y posteriormente evaluadas mediante microscopía óptica y análisis estadístico. Los resultados obtenidos indican que no hay diferencias entre los grupos en cuanto a la expresión de glucosa/manosa en epitelio y glándulas gástricas, pero sí se presentan diferencias significativas en la expresión de este glicoconjugado en lamina propia entre el grupo gastritis aguda positivo a Helicobacter sp con respecto a los grupos gastritis aguda negativo a Helicobacter sp. y grupo con mucosa normal. Los resultados estadísticos revelan que existe relación entre el aumento en la marcación de glucosa/manosa y la presencia de Helicobacter sp en lamina propia de mucosa gástrica de cerdos.

En la República Argentina la producción de carne ovina es impulsada por políticas del sector a fin de incrementar el volumen faenado y el consumo per cápita. Para certificar la inocuidad de estas carnes es indispensable la inspección sanitaria. En el post-mortem resulta imprescindible el examen de los nódulos linfáticos (NL) a fin de emitir un criterio sanitario sobre las reses inspeccionadas por parte del inspector veterinario en playa de faena frigorífica. Para ello, se identificó y describió forma, tamaño, situación, aferencias y eferencias de cada linfocentro. Para el estudio se utilizaron 8 ejemplares adultos de ambos sexos, a los cuales se les realizó eutanasia e inyección de tinta china a fin de que se visibilice el drenaje linfático para la ulterior disección. Se identificaron y describieron los linfocentros parietales externos del miembro pelviano, como ser los NL pre-femorales y NL poplíteos. Así mismo de igual manera se realizó con los linfocentros parietales internos del mismo miembro, estos fueron los NL retro-mamarios, NL inguinal superficial, NL isquiáticos, NL ilíacos externos, NL ilíacos internos y NL ilíacos medios. Los resultados obtenidos difieren en parte lo descrito por otros autores, debido principalmente a la inconstancia y a la no descripción de linfocentros por los mismos. No obstante, la descripción permitirá adecuar el sistema de inspección veterinaria post-mortem en playa de faena y de esta manera establecer los criterios sanitarios de reses faenadas e inspeccionadas.

Comic books can be and are produced mainly for science communication. Comics are more favorable to be read by the students as comics engaged students in reading compared to thick science textbooks. This study explored the role of comics as an aid in teaching elementary school science on the topic of ‘Plant Systems’ using an action research approach. A total of 18 Grade 5 students from one of the elementary schools in Brunei Darussalam participated in the study. A 15-page fully colored comic featuring a leaf fairy character called ‘Nym’ was utilized to teach the students alongside various activities about plants during the intervention lessons. A pre-test was administered prior to the lesson to establish their existing knowledge of the topic, and then a post-test administered after all the intervention lessons were completed. The results from the achievement scores analyzed between the pre- and post-tests indicated that the students’ knowledge on ‘Plant Systems’ improved significantly. The students were found to be interested, engaged and enthusiastic in the use of comics as revealed from the thematic analysis of the interviews. There are also vast potentials for comics to be used regularly to support learning in science-related classrooms.

This study aims to analyze the learning process of introverted students on algebraic operating materials and determine the results of treatment with Problem Based Learning on students' mathematical reasoning abilities. This type of research is an experiment with a single subject or Single Subject Research. The design used is A-B. Data collection techniques through observation, tests, interviews, and documentation. Data analysis uses analysis in conditions and analysis between conditions. Based on the results of the study, the introverted student learning process on algebraic operating material is the subject preparing needs, making designs, identifying, finding and delivering solutions, and conducting evaluations. While the treatment results in the form of Problem Based Learning showed a significant increase, the mean level of test results increased from 48.75 to 92.75 and the percentage of overlap was 0. It was concluded that the use of PBL models had a positive influence on the mathematical reasoning ability of introverted students. It is hoped that the Problem Based Learning model can be used as an alternative learning model to improve the mathematical reasoning ability of introverted students and learning when at school.

Integration of technology in science instruction in special education context can be done within the technological, pedagogical, and content knowledge (TPACK) framework. Therefore, special education teachers are expected to have a good level of TPACK. This study aimed to explore the level of teachers TPACK in science instruction for students with special needs and to compare the TPACK level of teachers based on their gender. This research used a quantitative approach with survey method. The respondents of this study were special education teachers (N= 44). The data collection method was through a survey using the TPACK survey instrument. The validation result used the Pearson Correlation showed value per statement ranging from 0.504 - 0.904. Reliability showed in the Cronbach's coefficient Alpha for internal consistency value of 0.856 (high). The data analysis technique used was the descriptive statistical analysis technique and the independent sample t test. The results showed that the total average of all TPACK domain is concluded in good category with mean score 81.29. The t test calculation showed that the t value (0.123) is less than the critical t value in the t table (2.085). The p value obtained was 0.90, greater than 0.05. Therefore, Ho is accepted. The issue of gender equality that has begun to be implemented in Indonesia can be the reason for the loss of technological mastery differences. In conclusion, TPACK mastery of special education teachers in science instruction was not differentiated by teacher gender with p>0.05.

Several facts about learning mathematics in high school, show that students' mathematical thinking skills are still low. Therefore, there needs to be an effort to increase these variables, considering that these variables are very important in supporting students' academic achievement. This study discusses the application of a comprehensive mathematics instruction (CMI) model in mathematics learning as an effort to improve students' mathematical thinking. This research is a quasi-experimental research. The sample was taken purposively from the population of high school students in Subang Regency, West Java, Indonesia. The instruments used in the research consisted of a mathematical thinking ability test and an observation sheet. Mathematical thinking ability is built by four important aspects, namely specializing, generalizing, conjecturing and convincing. The CMI model is a learning model that accommodates three stages, namely develop, solidify and practice. Each of these stages provides the opportunity for students to develop specializing, generalizing, conjecturing and convincing aspects. The results showed that the CMI model can improve students' mathematical thinking abilities. Thus, the CMI model deserves to be used as an innovation in mathematics learning.
