Authors: López-Paredes Marco , Carrillo-Andrade Andrea
Published: April 2024

El fenómeno de las ultramediaciones surge de la evolución de la ecología de medios, la convergencia y la hipermediación, en función de la tecnología y del ser humano, visto como artífice de su desarrollo. Así como pasa en la teoría económica, en las ultramediaciones las redes generan patrones de comportamiento y las interacciones influyen en los resultados de coordinación y cooperación. Entonces, una diversidad de acciones es sostenible con ciertas estructuras de red, pero no con otras; por lo tanto, las personas funcionan como nodos de acuerdo con diferencias en sus conexiones y su historia dependerá de la red a la que pertenezcan. Esta investigación aborda las bases de las ultramediaciones y analiza cómo se integra Ecuador a este fenómeno a través de la exploración de variables recopiladas en la Encuesta de Propósitos Múltiples 2019 y la Encuesta de Empleo 2022 del Instituto Nacional de Estadísticas y Censos (INEC). Se concluye que en Ecuador la pandemia redujo la brecha en el uso de las redes sociales, lo cual puede interpretarse como una mejor asimilación y participación de las conexiones entre nodos y usuarios en las ultramediaciones; sin embargo, la penetración de internet sigue siendo el primer obstáculo para crear un desarrollo más igualitario.

Published: April 2024

Introduction: Engaging students in small-group active learning methods is essential for their development. Yet, medical teachers frequently face difficulties in stimulating this engagement, resulting in students remaining passive or detached from the learning process. The aim of this study was to uncover ways in which expert medical teachers, proficient at cultivating high levels of student engagement, stimulate such engagement. This knowledge might inform faculty development initiatives, so that medical teachers can be better equipped to teach in a way that engages students.
Methods: We conducted an interview study using a constructivist grounded theory approach, integrating elements from appreciative inquiry. The eleven participants were qualified medical teachers who repeatedly received high scores on student engagement. Each interview was transcribed, coded, and analyzed using constant comparison until theoretical saturation was achieved.
Results: We constructed a grounded theory of expert teaching practice, describing student engagement as an integrated process consisting of three components: 1) aiming for a supportive learning environment; 2) employing a personal educational approach; and 3) facilitating the active learning process.
Discussion: This study uncovered that there are multiple ways to stimulate high levels of student engagement. Although there was consensus on the importance of a supportive learning environment and the ability to facilitate the active learning process, participants recognized the contextual nature of student engagement and took on a reflective mindset to adapt strategies to their specific situations. These findings highlight the need for faculty development initiatives to adopt a comprehensive, context-sensitive approach that considers the complexity of student engagement.

The accelerated development of urbanisation brings with it environmental problems and adverse effects on human health. Air pollution, water pollution and limited access to natural resources are becoming serious challenges. However, innovative products incorporating enterosorption technologies present a potential solution to improve public health. These products contribute to the effective removal of toxic substances from the body, mitigating the negative health effects of urbanisation.In the context of yoghurt with LABR, it has been found to be more stable to whey separation and moisture retention. Prebiotics have a positive effect on water retention, although this effect may diminish over time. The optimal concentration of LABR bacteria also emphasises the importance of a precise balance, after which additional increases do not bring significant improvements. These results can be used to optimise the production of yoghurt, taking into account its structure and properties over its shelf life.Considering the study data, it can be concluded that an optimal combination of L. acidophilus bacterial concentration and metal concentration, reached on the fourth day after the addition of prebiotics, is necessary to maximise the efficiency of heavy metal bioremediation. These results have practical implications for heavy metal removal processes in aqueous media, providing a basis for optimising bioremediation conditions in industrial and environmental applications.

The inclusion of cottage cheese products with a high content of collagen in the diet of athletes helps to strengthen the cartilage tissue of joints, improve the restoration of connective tissue of the ligamentous apparatus and reduce the pain threshold by increasing collagen production. Based on the study of the chemical composition of secondary products of the poultry processing industry, such chicken parts as skin, bone tissue and paws were selected to obtain a collagen-containing concentrate. A method for producing a dry collagen-containing concentrate has been developed. To obtain a collagen-containing concentrate, a method based on an enzymatic process using the papain enzyme for the hydrolysis of raw materials was chosen. This method allows you to preserve the biological value of collagen due to the gentle processing of raw materials. As a result of experimental studies, it was found that the collagen-containing concentrate contains polyunsaturated omega-3, omega-6 and omega-9 fatty acids with antioxidant properties. The result of the study of nutritional and biological value confirms the validity of the use of collagen-containing concentrate in the production of cottage cheese product for sports nutrition. A curd product enriched with collagen can be intended not only for athletes, but also for people who play sports for recreational purposes.

Water is useful for its properties and as a result gained such wide popularity. It is important to consider that water is the most accessible, widespread and environmentally friendly substance on Earth. Water has low viscosity, high density, good heat transfer coefficient, low cost, and water does not require disposal. In addition to these properties, water also has a high heat capacity, which makes it an efficient heat transfer medium. This means that it is able to absorb and transfer large amounts of heat without a significant change in temperature. This is especially important in heat transfer systems where heat transfer efficiency plays a key role. It worth noting that water is responsive to temperature regulating. Natural water also has disadvantages, such as the possibility of corrosion processes with the formation of metal oxides (rust) and thus destruction of equipment surfaces, limescale formation on heating surfaces when heated to temperatures above 80 degrees Celsius. Therefore, it is necessary to carry out appropriate physical and chemical treatment of water to ensure all the requirements that applied to the water coolant. Certain quality indicators, processing methods and schemes, as well as equipment protection methods have been established for water. The article presents data on determining the dependence of a number of indicators of water quality taken from the water of the Irtysh River for use at Semey CHPP-1.

This article presents the results of qualitative and quantitative analysis of whole and germinated (damaged) seeds of wheat variety «Kanadskaya». An extract was obtained from germinated (damaged) wheat grain by supercritical fluid CO2-extraction. According to the results of phytochemical analysis, carbohydrates, amino acids, flavonoids, and fatty acids were detected in the composition of CO2-extract. Using gas chromatography method, the extract was found to contain 14 fatty acids, most of which were methyl myristate (42,57%), methyl decanoate (25,85%), methyl ester of cis-10-pentadecenoic acid (16,80%) and methyl palmitate (7,35%). No significant difference was observed in the extract obtained from the damaged variety of wheat «Kanadskaya» in comparison with CO2-extract obtained from pure whole grain of wheat «Uralosibirskaya 2». Only the amount of methyl laurate was 4 times less, methyl stearate – 12 times less, methyl ester of cis-10-heptadecenoic acid – 3 times less. On the contrary, in the CO2-extract obtained from damaged wheat, the amount of methyldecanoate was higher by 4,48% and methyl ester of cis-10-pentadecenoic acid by 14,52%. In addition, methylundecanoate, methyl palmitate and methyl behenate of saturated fatty acids were found in this extract, which were not present in the CO2-extract obtained from pure whole wheat grain «Uralosibirskaya 2». It should also be noted that representatives of unsaturated fatty acids were detected in the CO2-extract obtained from the damaged variety of wheat «Kanadskaya». In total, their share amounted to 19,7%. According to the results of capillary electrophoresis, the proportion of vitamin B1 from B vitamins was higher and amounted to 0,13±0,03 mg/100 g; however, compared to the normal amount, this figure was 3 times lower. The proportion of amino acids was also very low, with phenylalanine content being slightly more dominant at 0,098%. Vitamin E content (0,72 mg/100 g) was determined by high-performance liquid chromatography, while vitamin A was absent in the extract.

In this article it was demonstrated that potassium ethyl carbonate can be successfully utilized within the phenol and its derivatives carboxylation. The optimal reaction conditions for m-cresol were determined: substrate to potassium ethyl carbonate ratio 2:1, temperature 180°C, pressure 10 atmospheres and reaction time 6 hours. Importantly, the carboxylation of m-cresol is selective and resulted in the obtaining of 4-methyl-2-hydroxybenzoic acid in 90% yield.To study the impact of the nature and location of substituents in the phenyl ring on the yield of the desired products, carboxylation reactions of various phenol derivatives were carried out with the use of potassium ethyl carbonate. As a result of the investigation, the optimal carboxylation reaction parameters for each of the phenol derivatives were determined.This study may have practical applications in the development of laboratory and manufacturing approaches for the synthesizing of valuable hydroxybenzoic acids and their derivatives. It was discovered that carboxylation of phenol derivatives by potassium ethyl carbonate occurs via electrophilic substitution of the aromatic ring. The most active in this reaction are p-cresol (84%), mcresol (90%), o-cresol (80%) and resorcinol (73%). It was observed that p-chlorophenol (18%), pbromophenol (48%) and p-fluorophenol (58%) showed less pronounced activity.

In this study, the antioxidant properties of extracts, the total content of phenols and flavonoids were studied from some essential oil medicinal plants growing on the territory of East Kazakhstan region, in particular yarrow (Latin Achillea) and wormwood (Latin Artemisia). Three solvents, distilled water, acetone and ethanol were used in the research work. The antioxidant activity of the extracts was determined by dpph, ABTS, β-carotene/linoleic acid and phenolic, flavonoid compounds. The results related to the applied methods and solvents (polar, apolar) were obtained. For example, the ABTS cationic radical removal method showed that the highest antioxidant activity in both plant types was demonstrated by the same acetone solvent (Achillea 344.11 and 0.06 mg/ml, Artemisia 198.26 and 0.07 mg/ml). DPPH showed the strongest effect of radical removal in distilled aqueous solvent (Achillea 245.82±1.59 mg/ml, Artemisia 300.53±1.18 mg/ml) in both species using the method of determining the activity of free radical removal. In addition, when studying total phenol, flavonoid compounds, the total amount of phenols in various solvent extracts obtained from Achillea ranged from 0.13 mg/ml from 59.71 to 0.13 mg/ml from 96.16 to 0.21 mg/ml, and the amount of flavonoids ranged from 0.11 mg/ml from 38.22 to 86.65 from 1.17 mg/ml. While the phenol content in Artemisia extracts ranged from 40.75 mg/ml to 113.56 mg/ml to 0.91 mg/ml, the flavanoid content ranged from 22.74 mg/ml to 74.94 mg/ml to 1.97 mg/ml.

The scientific article is devoted to the study and application of micro-arc oxidation technology for the restoration of the working surfaces of truck pistons. The study includes an analysis of the physical and chemical processes occurring during microarc oxidation of aluminum alloys from which the pistons are made. The physical impact of MAO promotes the formation of a strong and stable oxide layer, leading to improved surface morphology and closure of microcracks. The results obtained confirm that this technology promotes the formation of hard coatings. The presence of microcracks and surface defects on the original surface of the aluminum alloy caused by operation is noted. After applying the micro-arc oxidation procedure, significant improved surface morphology, reduction of microcracks and removal of defects are visible, indicating the high efficiency of the process. The use of micro-arc oxidized coatings in mechanical engineering promises to increase the durability and efficiency of freight vehicles, as well as reduce repair and maintenance costs. This research represents an important contribution to the field of technological solutions for the remanufacturing of vehicle parts, providing promising prospects for industrial applications.

A incidência da dengue, doença viral transmitida pelo mosquito Aedes aegypti, vem crescendo em Porto Alegre ao longo dos anos, com recorde de casos registrados em 2022. Epidemias da doença parecem ocorrer de forma cíclica no município, com registros a cada três anos. Dada a influência de fatores climáticos no ciclo de vida do vetor, este trabalho buscou analisar a influência de determinantes meteorológicos na periodicidade de epidemias de dengue na capital gaúcha entre 2010 e 2022. Análises descritivas foram realizadas para averiguar o padrão dos indicadores climáticos e dos casos de dengue ao longo dos anos, ao passo que análises estatísticas foram feitas para avaliar a correlação entre os fatores climáticos e os casos autóctones registrados entre 2016 e 2022. Os resultados obtidos não apontaram padrões meteorológicos que se repetem a cada três anos e que poderiam explicar a ciclicidade observada. Ainda, não foram constatadas correlações entre temperatura, umidade e pluviosidade com casos autóctones de dengue no município, ao menos em nível quadrimestral. Para além destas análises, constatou-se expressivo aumento de casos em 2022, apesar dos esforços de controle desempenhados pelo poder público, o que aponta a necessidade de maior investimento em educação em saúde para a população.
