Modelo didáctico para la enseñanza de la metodología de la investigación científica
Authors: Claure José L. 
Published: October 2020

Hablar de la enseñanza de la metodología de la investigación científica en la formación profesional es hablar de la formación en y para la producción y difusión de conocimiento científico, a través de la investigación científica y la interacción social universitaria. Asumiendo que esta es la misión de la Universidad, desde la denominada sociedad del conocimiento, en Bolivia se nos remite al modelo educativo que se ha propuesto encarar como política estatal denominado Socio Comunitario Productivo (MEC, 2009)
Lo dicho no resulta novedoso, puesto que el Sistema de la Universidad Boliviana, en su VIII Congreso Nacional (CEUB, 1995) resuelve asumir el paradigma productivo, como respuesta a una de las mayores preocupaciones de la sociedad con referencia a la calidad de la Educación Superior cual es la producción del conocimiento desde la investigación, manifestando con ello que es su responsabilidad crear las bases de un nuevo poder, que es el conocimiento y la racionalidad científica. Si bien esta resolución empieza a concretarse con la creación de Institutos de Investigación, la inclusión de la asignatura de Metodología de la Investigación en los Planes Curriculares de todas las Carreras y la implementación de modalidades de titulación que impliquen tanto la investigación cuanto la interacción social, no se ha avanzado en la difusión de trabajos de investigación realizados por los estudiantes durante su formación profesional. Esto quiere decir que tampoco se han desarrollado procesos de enseñanza aprendizaje orientados a la formación de competencias para la producción y difusión de conocimiento científico.

Objetivos: el presente estudio evalúa el cambio en las perspectivas, conocimientos, actitudes y prácticas de los familiares de un grupo de pacientes capacitados con la estrategia de educación por pares que fueron tratados en la Plataforma de atención integral de Chagas, y si ese cambio se traduce en un aumento de la demanda de atención integral de Chagas en los servicios de salud del Valle Alto de Cochabamba. Métodos: se comparó los resultados de la encuesta realizada en 32 familiares de 8 pacientes capacitados en 2018 (grupo A) con una encuesta similar realizada en 64 familiares de 16 pacientes tratados en 2017 (grupo B) que no fueron capacitados, pero en cambio recibieron la consejería que provee el personal de salud de forma rutinaria. Resultados: los resultados obtenidos muestran que los familiares de pacientes educadores pares han modificado sus conocimientos, actitudes, prácticas y percepciones sobre la enfermedad de Chagas y este cambio ha influido positivamente la demanda de atención de servicios integrales para dicha enfermedad. Conclusión: la estrategia de educación por pares ha demostrado ser eficaz, fácil de aplicar por un personal de enfermería en los 1º y 2º niveles de atención, y que permite llegar a las familias afectadas a un costo relativamente bajo.

<p>La obra de Enric Miralles y Benedetta Tagliabue (EMBT) para el Campus de la Universidad de Vigo, situado en la borrosa frontera disciplinar de la arquitectura y el paisajismo, se revisa prestando especial atención a la esfera del espacio público. Por primera vez, se recurre a la arquitectura clásica de la polis griega, para interpretar la propuesta del CUVI, confrontándola con sus espacios públicos arquetípicos, revelando una dimensión clásica en la obra de Miralles y Tagliabue. El texto recopila algunas de las intenciones primigenias del proyecto, desvela algunas fuentes de inspiración, e identifica algunos elementos del imaginario personal de sus autores.</p>
Cyclic and square-wave voltammetry for selective simultaneous NO and O&lt;sub&gt;2&lt;/sub&gt; gas detection by means of solid electrolyte sensors

Published: October 2020

Abstract. Solid electrolyte gas sensors (SESs) based on
yttria-stabilized zirconia (YSZ) are suitable to detect traces of redox components
in inert gases. Usually, their signals are generated as a voltage between
two electrodes at open circuit potential or as a current flowing between
constantly polarized electrodes. In these rather stationary modes of
operation, SESs often lack the desired selectivity. This drawback can be
circumvented if SESs are operated in dynamic electrochemical modes that
utilize the differences of electrode kinetics for single components to
distinguish between them. Accordingly, this contribution is directed to the
investigation of cyclic voltammetry and square-wave voltammetry
as methods to improve the selectivity of SESs. For this, a commercial SES of the type “sample gas, Pt|YSZ|Pt, air” was exposed to mixtures containing NO and O2 in
N2 in the temperature range between 550 and 750 ∘C. On cyclic voltammograms (CVs), NO-related peaks occur in the cathodic direction
at polarization voltages between −0.3 and −0.6 V at scan rates between
100 and 2000 mV s−1 and temperatures between 550 and 750 ∘C.
Their heights depend on the NO concentration, on the temperature and on the
scan rate, providing a lower limit of detection below 10 ppmv, with the
highest sensitivity at 700 ∘C. The O2-related peaks,
appearing also in the cathodic direction between −0.1 and −0.3 V at scan
rates between 100 and 5000 mV s−1, are well separated from the
NO-related peaks if the scan rate does not exceed 2000 mV s−1. Square-wave voltammograms (SWVs) obtained at a pulse frequency of 5 Hz, pulses of 0.1 mV and
steps of 5 mV in the polarization range from 0 to −0.6 V also exhibit
NO-related peaks at polarization voltages between −0.3 and −0.45 V
compared to the Pt–air (platinum–air) electrode. In the temperature range between 650 and
750 ∘C the highest NO sensitivity was found at 700 ∘C.
O2-related peaks arise in the cathodic direction between −0.12 and −0.16 V,
increase with temperature and do not depend on the concentration of NO.
Since capacitive currents are suppressed with square-wave voltammetry, this method provides
improved selectivity. In contrast to cyclic voltammetry, a third peak was found with square-wave voltammetry at
−0.48 V and a temperature of 750 ∘C. This peak does not depend on the
NO concentration. It is assumed that this peak is due to the depletion of an
oxide layer on the electrode surface. The results prove the selective
detection of NO and O2 with SESs operated with both cyclic voltammetry and square-wave voltammetry.

Published: October 2020

This study uncovered the chemical changes during kombucha's fermentation process and revealed the associated immunomodulatory activity in Salmonella typhi-infected mice. The snake fruit juice and black tea extract were processed into kombucha (a beverage known for its health benefits) by fermentation with SCOBY culture at room temperature for 14 days. Snake fruit kombucha showed high changes in fermentation parameters (total acidity, pH, and total sugar), as well as bioactive compounds and antioxidant activity. Salmonella typhi demonstrated a reduction in the population of CD8+TNFα+ and CD4+IFNγ+ of infected experimental animals. Both snake fruit kombucha and black tea kombucha have the potential to be utilized as an immunomodulator to circumvent unstable conditions of the immune system caused by Salmonella typhi. Black tea kombucha and snake fruit kombucha cancan raise the production of CD8+TNFα+ and CD4+IFNγ+ in mice infected with Salmonella typhi. In the group of normal mice, black tea and snake fruit kombucha were able to lower down the production of CD8+TNFα+, which is a potent mechanism to modulate the immune system. Further research is required to highlight the mechanism and role of black tea kombucha and snake fruit kombucha in the immune response that modulates and treats infection by Salmonella typhi.

Published: October 2020

Abstract
Escolios contra Juan Baptista Pérez (c. 1594) is the shortened title of a burlesque work attributed to Juan Sáez de Zumeta, which remains unpublished in three known manuscripts. One of these, compiled by Porras de la Cámara, gives the news about the existence of the academy of San Vicente in Seville, where these Escolios were written. This article describes these testimonies and examines the structure of the piece and the different discursive modalities of the burlesque it shows. It also identifies the abovementioned academy with the burlesque literature produced in Seville in this period.

Authors: Martínez Víctor , Covarrubias Germán 
Published: October 2020

Este artículo trata sobre la promoción de la salud mental y la prevención de drogas en el sistema escolar. Se conceptualiza a las unidades educativas como comunidades escolares y se propone un modelo compuesto de 4 indicadores conceptuales relacionados con su capacidad de inserción contextual, sus reglas fundantes que establecen el campo de lo posible para las acciones e interacciones promocionales y preventivas (genoestructura), sus capacidades instaladas para producir actividades promocionales y preventivas (fenoestructura) y el flujo de producción de actividades promocionales y preventivas concretas (fenoproducción). En base a estos indicadores se obtiene un índice de capacidad promocional y preventiva de la comunidad escolar que permite evaluar, diseñar intervenciones, estrategias y políticas públicas en la materia.

Published: October 2020

Non-Destructive Testing (NDT) has gone from being a simple laboratory curiosity to an indispensable tool in the industry to determine the level of quality achieved in its products. The new concepts of Integrated Manufacturing (CIM) bring a more universal concept of quality compared to the past philosophy based on Quality Control as a group specialized in checking whether production works within certain specifications. Even so, NDTs have not lost interest, but have seen their interest increased due to automated inspection techniques. It has become a contribution to the structuring of quality as it allows to move from purely empirical criteria to other more objective and that constitute the link between design and evaluation (Ramirez et al, 1996).
The work presented, although it does not propose new methods or techniques of NDT, has the interest of converging into a single object five conventional methods each of which provides partial information about their quality of manufacture and must synthesize the results in order to evaluate it. Furthermore, it shows a situation of the application of NDT in which these must be applied in the absence of reference standards, as they do not exist. This peculiar situation is completely different from the usual situation in the use of NDT in the industry, both in manufacturing processes and in maintenance inspections.

Published: October 2020

Aim. Main aim of this research was identification of genetic distances between different genotypes of napa cabbage (B. rapa ssp. pekinensis) and diversity identification in var. glabra and var. laxa forms. Methods. Molecular genetic analysis of napa cabbage genotypes was conducted out using method of β-tubulin intron length polymorphism (TBP). Results. Molecular profiles of different napa cabbage (B. rapa ssp. pekinensis) genotypes were identified. Number of amplified β-tubulin intron fragments was significantly varying – from 12 to 24 for each genotype. Basing on obtained results a dendrogram was built, which shows genetic distances among studied accessions. Conclusions. In present study 7 genotypes of B. rapa ssp. pekinensis were analyzed, received from IPK (Gatersleben) and Crop Research Institute (Prague) gene banks. Basing on obtained results it was established that systematic diversification of two forms var. glabra and var. laxa is not being confirmed by molecular genetic methods, such as TBP, and in this case, genetic difference between populations and cultivars was more significant.

The role of biologically active substances and short AT-fragments of nucleic acids in the genetic transcription process
Authors: Kurchii B. A. 
Published: October 2020

The characteristic chemical fragments named as functional reactive groups (or descriptors) in the molecules of biologically active substances (BASs) are described. These fragments are characterized by the presence of an active hydrogen atom or unsaturated function. It is concluded that BASs are essential factors working in concert with gene keys and gene locks to starts transcription. The gene keys are nucleic acids but not proteins. It is postulated that cell membrane can serve as depot for gene keys at the beginning of oxidative stress. During the recession phase of oxidative stress new gene keys are synthesized for new transcription acts.
Keywords: BASs, descriptors, gene keys, gene locks, transcription.

Aim. PTLRW are the trenches and bursts for the localization of radioactive waste that were created during the first priority measures for elimination of the Chornobyl accident. The aim of the presented work was to characterize the microbial community structure on PTLRW. Methods. To describe the influence of environmental factors on the soil microflora, the agrochemical parameters of soil (pH, carbon, nitrogen, mobile potassium and phosphorus) were evaluated. Dose loading was calculated using the ERICA tool software package. The total lipid fraction was extracted with a modified Bligh-Dyer method. Results. The pH of the soil ranged from 3.0 to 3.9. The carbon content ranged from 0.95% to 2.11%. The exception was Red Forest from the trench/outside the trench where the carbon content was 2.52 and 1.98% and with a pH 4.5. Nitrogen content ranged from 33.6 mg / kg to 74.2 mg / kg. The PLFA content ranged from 15 μg / g to 18.9 μg / g, except Novoshepelychi and Zalissia (33.3 μg / g and 23 μg / g). Conclusions. In terms of the structural composition of the microorganisms, the PTLRW points were more homogeneous compared to the contaminated radionuclide ecosystems. In natural ecosystems, gram-positive bacteria were the main dominant group, unlike PTLRW where there were several groups.

Published: October 2020

Aim. The usage of biotic elicitors for elicitation of defense responses may induce plant disease resistance and prevent increased environmental pollution by pesticides. Hydrogen peroxide is a well-known signal molecule for photosynthetic status and for stomatal movements, and systemic acquired resistance to pathogens in plants proposed to be dependent on H2O2. The aim of research was to analyze in field trials the effect of oxalic, ferulic and kojic acid on H2O2 content and winter wheat resistance against Septoria tritici. Methods. Content of endogenous H2O2 was measured in elicitor treated and inoculated by S. tritici wheat plants (cv. Oberig) during different ontogenesis phases. The extent of disease development, morphometric parameters and yield structure were analyzed. Results. It is shown that the lowest level of hydrogen peroxide in leaves at the necrotrophic stage of pathogen infection was after oxalic acid treatment, and the highest – after koijc acid influence. Conclusions. The data obtained suggest that elicitors induced defense responses in winter wheat against S. tritici and hydrogen peroxide content is an important and valuable parameter.
