Authors: VURAL Selahattin , KESİCİOĞLU Tuğrul , AYDIN İsmail
Published: August 2022

Objective: Red cell distribution width (RDW) ,an index of heterogenity of circulating red blood cell, has recently been found to be associated with multiple diseases and used as a marker to predict outcome in these patients. In the present study we aimed to investigate if RDW value is associated with cholelithiasis and symptoms of the disease.Material- Method: A total of 204 women (101 with cholelithiasis and 103 without the disease ) were included to the study. The demographic and the laboratory data of the routine complete blood cell parameters including RDW values were recorded. Women with cholelithiasis were divided into symptomatic or non-symptomatic group according to presence of biliary colic or pain. The patients were compared in terms of their demographic and laboratory characteristics.Results: Age and BMI were similiar between groups in the study population. In our study population mean RDW value was signifi¬cantly higher in women with cholelithiasis than without disease. However in subgroup analysis there was no significant difference of RDW value between symptomatic group and nonsymptomatic group Conclusion: In conclusion we demonstrated an association between serum RDW level and cholelithiasis in our study but not with disease symptom. However further studies are needed to understand the role of RDW in patients with cholelithiasis and if this simple , inexpensive and routinely reported parameter can be used for prognostic information in this disease.

Published: August 2022

The majority of modern biomedical research is aimed at personifying the diagnosis and treatment of various diseases. An individual approach can be implemented using radiomics — the latest radiation diagnostics associated with the extraction of a large number (from hundreds to several thousand) of additional quantitative indicators from medical images using specialized software. The method is actively used in oncology to identify radiochemoresistant tumor zones, as well as non-invasive determination of the phenotype and genotype of the neoplasm. At the same time, the prospects for the application and clinical significance of this approach in cardiology have not yet been determined and have been the subject of active research in recent years. In this regard, the purpose of this review was to collect information from available databases and assess the degree of knowledge of the problem of radiomic analysis of heart images using various radiation modalities, as well as to determine the prospects for using this approach in clinical practice.

Published: August 2022

The onset of progressive deficit in multiple sclerosis (MS) was often determined retrospectively with difficulties in diagnostic. This is a case report with subtle MS progression. Clinical and structural MRI anamnesis was complemented with multivoxel 1HMRS examination. The patient complained of the walking distance reducing, gradually increasing spasticity in the distal parts of lower extremities, unsteadiness when walking, clumsy movements. Choline and myoinositol levels were predominantly increased in the area of the cingulate gyrus versus other gray matter regions and the same picture was observed in adjacent white matter. Multivoxel 1H-MRS represents a diagnostic tool that can be very useful in complex diagnostic of MS progression. Measuring chemical-pathological changes diffusely in brain tissues may detect distinctive for progression metabolic patterns.

Congenital hemangiomas are benign vascular lesions found in fetuses. Congenital hemangiomas develop in utero, have a maximum size at birth (in the absence of subsequent bleeding). Such hemangiomas occur in 1–2% of newborns. Prenatal ultrasound diagnostics and magnetic resonance imaging occupy an important place in the diagnosis, which determines the tactics of management and treatment of the patient. To present a clinical case of prenatal diagnosis of congenital soft tissue hemangioma of the fetal back. A pregnant woman A., 34, was sent to St. Petersburg State Public Health Institution «Diagnostic Center» (medical and genetic) with suspected spina bifida of the fetus after screening in late pregnancy period in one of the Birth Centres. Performed prenatal ultrasound (US) pregnant A. for a period of 34 weeks. According to ultrasound data in the region of the spine at the level of XI–XII thoracic vertebrae, an ovoid formation with clear even contours, a fairly homogeneous solid structure, with a clear capsule, 33×24×30 mm in size (volume 12.4 cm3) is determined subcutaneously. The diagnosis made: hemangioma of the soft tissues of the fetal back. Prenatal screening plays a key role in the diagnosis of congenital hemangiomas. Timely detection of this benign formation affects the tactics of management and delivery.

CONSTRUIR COLÔNIAS Reformas nas Américas c. 1760-90
Authors: Raminelli Ronald
Published: August 2022

Em perspectiva historiográfica e comparativa, o artigo analisa as reformas borbônicas e pombalinas. Essas intervenções se originaram das disputas entre as monarquias europeias e alteraram o pacto entre os reis e seus súbitos ultramarinos. Provocaram ainda revoltas comandadas por diversos setores da sociedade, mas essas reações diferiram bastante nas Américas. Reformas e revoltas elevaram as pressões econômicas e políticas no ultramar e tornaram mais nítidos os conflitos sociais. Antes pouco empregado, o termo “colônia” tornou-se mais usual e fundamental para entender os vínculos entre as monarquias e as possessões ultramarinas. Além de produzir em larga escala matérias-primas, as colônias destacaram-se pela mestiçagem e conflitos raciais.

Published: August 2022

Fraud exposes a business to a variety of significant financial risks that can threaten both its profitability and public image. All firms are almost certain to be victimized by some form of economic crime or fraud. As a result, the business world’s revolution in big data and data analytics plays a critical role in the establishment of competitive companies, as big data is already being used in a wide variety of industries (Rezaee & Wang, 2019) and is referred to as the next frontier in terms of productivity, innovation, and competition (Al-Marzooqi, 2021). This paper aims to explore how auditors use big data analytics to detect and prevent fraud in their audit work, the benefits, and barriers of incorporating big data analytics into audit practice. Methodologically, this study conducted a library search and evaluated prior literature reviews on the subject of big data analytics and the auditing profession. The resources span a range of items, from online and print sources to articles in journals and chapters in books. Numerous databases, including Scopus, Web of Science, Science Direct, and Google Scholar, were searched between 2011 and 2022 to compile literature on the subject. This paper makes recommendations on how to improve data analytics approaches for detecting and preventing fraud as well as discusses limitations and future studies.

Authors: Cerquera Losada Oscar Hernán , Manrique Parra Sergio , Ovalle Díaz Astrid Lorena
Published: August 2022

El propósito de este artículo es realizar un análisis teórico de los principales modelos de agentes heterogéneos en el contexto de la actual pandemia mundial de covid-19. Los típicos modelos de agente representativo usados en el análisis de política macroeconómica han dejado de ser relevantes, pues la evidencia empírica ha mostrado que existe una gran cantidad de agentes heterogéneos que responden de maneras diversas en la realidad. Para el análisis se parte de los planteamientos pioneros de Friedman acerca de la función consumo, se incluyen elementos como las restricciones de liquidez que deben enfrentar los individuos, se referencian los modelos HANK y TANK aplicados a diferentes contextos y, finalmente, se realiza un acercamiento teórico al análisis de la situación actual de pandemia en el marco de los modelos estudiados.

Published: August 2022

Este artículo ofrece una aproximación al desarrollo en Colombia a través del análisis de la Ley 1735 de 2014, conocida también como la “Ley de Inclusión Financiera”. La metodología usada fue de orden cualitativo y las técnicas fueron la revisión e investigación documental, dándole especial preponderancia a fuentes primarias como el cuerpo de la Ley y su exposición de motivos. La importancia de este trabajo radica en que la inclusión de todos los agentes económicos en el sector financiero es un elemento vital para el desarrollo económico de un país. El principal objetivo al cual responde este artículo es analizar el contenido de la Ley de Inclusión Financiera en Colombia. Se encontraron disposiciones normativas de similar espíritu en Latinoamérica (Perú y Uruguay). Como hallazgo central, se pude indicar que la Ley 1735 de 2014 no trata sobre inclusión financiera, pues versa sobre la regulación de un nuevo tipo de agente económico llamado Sociedades Especializadas en Depósitos y Pagos Electrónicos (SEDPE).

Published: August 2022

Esta investigación tuvo por objetivo indagar sobre el uso del portafolio como instrumento de evaluación de desempeño en una institución educativa ecuatoriana que trabaja bajo el modelo educativo basado en destrezas. Se tomó como marco de referencia lo indicado por el Ministerio de Educación para el curso de Matemáticas en el primer año de educación media superior. También se diseñó la investigación bajo la metodología del estudio de caso, integrando el enfoque mixto, y se recogieron datos cuantitativos y cualitativos para comprender mejor el fenómeno. En el estudio participaron 22 estudiantes. Con el fin de estimar la utilidad del portafolio como herramienta de evaluación de desempeño, se diseñó una rúbrica, basada  en una taxonomía de aprendizaje orientada a clasificar procesos de pensamiento, y un cuestionario. Más tarde, se analizaron las evidencias contenidas en los portafolios de tres estudiantes y se compararon los resultados de evaluación. Además, se integró al análisis la percepción de estudiantes del mismo grado y grupo académico con respecto al uso de portafolios. Los resultados permiten inferir la utilidad del portafolio como instrumento de evaluación, dado que, aparentemente, favorece el proceso de aprendizaje y el desarrollo de destrezas. Por último, se integran sugerencias sobre posibles estudios futuros en cuanto al diseño y la aplicación del portafolio en el aula.
Tránsito histórico de la pornografía

Published: August 2022

La pornografía en internet se presenta como un fenómeno sin precedentes en la historia de la humanidad. Este trabajo expone una revisión teórico-histórica que da cuenta de las transformaciones culturales y sociojurídicas que permitieron su conformación, y al mismo tiempo destaca los rasgos distintivos que la separan cualitativamente de formas similares de material erotizante. En un movimiento dialéctico, caracterizado inicialmente por la unión entre sexualidad y divinidad, posteriormente por una era oscura de censura y opresión y, finalmente, por una nueva liberación como mercancía y entretenimiento en la era de la información, la pornografía ha sufrido transformaciones vertiginosas que adelantan con creces el estudio de la academia, particularmente en nuestra realidad latinoamericana.

Authors: Botello-Peñaloza Héctor Alberto , Guerrero Rincón Isaac
Published: August 2022

La pandemia de coronavirus ha provocado alteraciones en las cadenas de producción mundiales. Por ello, resulta importante analizar el impacto de este fenómeno en las empresas de diferentes sectores económicos, especialmente en aquellos países con menor capacidad de respuesta ante la emergencia sanitaria. Así, el objetivo de este trabajo es determinar el impacto de la pandemia de covid-19 sobre el desempeño de las empresas de cuatro países centroamericanos. Mediante el uso de datos longitudinales de la encuesta empresarial del Banco Mundial, se empleó un modelo de diferencias con el fin de estimar el impacto de este fenómeno global, considerando características tanto internas como externas. Los hallazgos muestran que las consecuencias económicas durante el período analizado de la pandemia es significativo, puesto que cerca de 2 % de las empresas cerraron permanentemente y 60 % de manera temporal. Las ventas totales y las ventas por empleado cayeron alrededor de 30 %, con resultados más adversos para las firmas que cerraron temporalmente debido a las restricciones impuestas. No obstante, la respuesta inmediata de los gobiernos por medio de créditos fiscales e incentivos ha permitido satisfacer las necesidades de liquidez a corto plazo de las compañías en los países analizados.

Could rhombic shaped miniplates be applicable for subcondylar fractures of mandible?: A biomechanical study
Authors: ATAOL Mert , ÖZCAN-KÜÇÜK Ayşe
Published: August 2022

Purpose: Fractures of the mandibular condylar process are the
most common fractures in the maxillofacial region. Surgical treatment of
condylar region fractures with miniplates and miniscrews has become
quite popular because it is a stable method and allows for immediate
function. The present study examined sheep hemimandibular subcondylar
fracture models to evaluate the biomechanical properties of two
miniplate/screw system types, which are used to surgical fixation of
subcondylar fractures. Experimental: The experimental
standardized subcondylar fracture lines were examined in ten sheep
hemimandibula models. Each segment was fixated with one of two fixation
types: double straight miniplates with eight miniscrews or single, one
rhombic-shaped miniplate with five miniscrews. All models were mounted
in a servohydraulic testing unit, and continuous linear force was
loaded. The maximum force and displacement values were compared and
analyzed statistically. Results: The rhombic miniplate group
had statistically significantly lower values than the double straight
miniplate group for maximum force, work at maximum load, and hardness.
There was no statistically significant difference between the two groups
in terms of displacement at maximum load. Conclusion:
Considering the advantages of rhombic shaped miniplates, they are
suggested as a clinically reliable treatment alternative for the
surgical fixation of subcondylar fractures.

Characterization of thermal properties of different ages highland bamboo
fiber attributes extracted chemically and mechanically is the focus of
this work. The sample ware subjected to different analyses for each
corresponding age (1year, 2years, and 3 years) and NaOH Concentration
(untreated, 1%, 2%, and 3%) levels using thermogravimetric analysis
(TGA), differential scanning calorimetric (DSC), differential
thermogravimetric analysis (DTG), and differential thermal analysis
(DTA) for thermal properties characterization. Scanning electron
microscopy (SEM) for morphological studies and Fourier transform
infrared spectroscopy (FTIR) for the identification of functional groups
of the fibers. The surface appearance of the cell wall and microfibril
aggregates were changed by alkali treatment. From the SEM results, 3%
NaOH treated fiber resulted in more wrinkles on the surface of bamboo
fibers when compared with the 1% and 2%NaOH Bamboo fiber. Using
thermal analyse measurments, the study investigated weight loss
increased as alkali concentration increased but the scenario functioned
for proper concentration. The first Degradation stage is responsible for
the biggest weight loss since it includes the disintegration of all of
the fiber’s primary components (cellulose, hemicellulose, and lignin).

The movement of fine bubbles in a swirling field determines the mass
transfer, heat transfer, and reaction performance of the swirl
equipment. This study investigated the separation of fine bubbles
strengthened by a swirling field in order to achieve higher separation
efficiency of the planar cyclone through optimizing the structure of the
convection field. The bubble size and gas holdup in the swirling flow
field under different working conditions were explored by combining
high-speed camera online measurement and computational fluid
dynamics(CFD) simulation. The gas holdup and bubble size of each region
in the swirl region, as well as the separation efficiency of gas by
swirl eccentricity, were observed at different liquid and gas Reynolds
numbers, Re and Re,
respectively. Furthermore, the influence of different swirl
eccentricities, d, was investigated. It found
that the highest separation efficiency can be achieved under all working
conditions when swirl eccentricity d= 5 mm.
The Investigation of Flow Characteristics in Nanofluids Under Magnetic Field
Authors: AYTAÇ Zeynep
Published: August 2022

The existence/application of an externally induced magnetic field, like in satellite cooling applications, causes a decrement in heat transfer when used with nanofluids. This study investigates the flow characteristics and velocity profile of distilled water, alumina nanofluid, and cobalt ferrite ferrofluid in a horizontal cylindrical heat pipe flowing in a laminar regime and being exposed to an external magnetic field. All of the simulations were performed with ANSYS Fluent MHD module, for a concentration of 2%, Reynolds number of 10, and Hartmann numbers of 25, 50, and 150. The velocity profiles, pressure drops, and flow characteristics are examined by varying the magnetic field intensity while keeping all other parameters constant. It is concluded that an external magnetic field causes a deterioration in the velocity profiles of the nanofluid, especially in cobalt ferrite, while it does not have a significant effect on water. When the magnitude of the magnetic field is increased by 2 times, it is seen that the velocity of the fluid decreases by 6% and increasing the magnetic field from 0 to 50 Tesla causes a deceleration rate of 9%, which leads to the conclusion that application of a magnetic field for the first time has a more significant slowing effect when comparing it to increasing the magnetic field. In addition, when a magnetic field of 50 Tesla is considered, the maximum velocity of alumina is lower than that of water by 5.10%, and the maximum velocity of cobalt ferrite is lower by 28.57%.

This study aimed to evaluate the effect of desensitizing and conventional mouth rinses on dentin tubule occlusion. Dentin hypersensitivity was simulated by EDTA application for five minutes. The specimens were randomly allocated into the following groups: desensitizing mouth rinses (Colgate Sensitive, Elmex Sensitive Professional, Listerine Advanced Defense Sensitive, Sensodyne Cool Mint); conventional mouth rinses (Colgate Plax, Elmex Caries Protection, Listerine Anticaries, Sensodyne Pronamel); a negative control (C−: distilled water); and Clinpro XT Varnish was the positive control (C+). Subsequently, the specimens were submitted to an erosive or abrasive challenge (performed separately) and to an erosive/abrasive cycling for five days (n=10 for each challenge). After treatment, challenges, and cycling, the specimens were analyzed in an environmental scanning electron microscope to verify the number of open dentin tubules (ODTs), counted by using Image J software (National Institutes of Health, Bethesda, MD, USA). Data were analyzed by the Kruskal-Wallis, Friedman and Dunn tests, with Bonferroni correction (α=0.05). Groups did not differ at baseline (p>0.05). At the post-treatment, erosion and abrasion stages, C+ was the only group that showed a reduction in ODTs compared to C−(p<0.05). In the other groups, numbers did not differ significantly from C− (p>0.05). After cycling, none of the groups exhibited significant reduction in ODTs other than C− (p>0.05); however, C+, Listerine Anticaries, and Colgate Plax had a lower number of ODTs than Listerine Sensitive and Sensodyne Pronamel. No mouth rinse was able to promote significant occlusion of the dentin tubules after treatment and the challenges. C+ was the only product that effectively promoted tubular occlusion, but this effect did not withstand several erosive and abrasive challenges.

The dependence of the location of singular points of orthorhombic (ORT) media on the stiffness coefficients , and phase velocity  at the singularity point is studied under the assumption that  are larger than  and . In this case, singular points appear only at the intersection of slowness surfaces of S1- and S2-waves. To simplify the presentation of the results, the values , are fixed and  changed within the limits at which the stiffness matrix remains positive definite. We define the parameters, , , , which result in 0, 1, or 2 singular points in the symmetry planes of the ORT medium. The types of these singular points and their location on the unit circle are described. It is shown that, by selecting parameters , any singular point in the symmetry plane 13 can be combined with the limiting position of the singularity point in-between the symmetry planes, or this point can be included in the singular curve of the degenerate ORT medium. We derive equations for the semi-axes of an ellipse of conical refraction, which is the image of a singular point from plane 13 in the group domain. Conditions for degeneration of the ellipse of conical refraction into a segment or a point are defined. It is shown that there exists only one ORT medium with a fixed phase velocity  of S1- and S2-waves in a given singular direction n. If we present the ORT media as projections of these vectors n onto the plane 12 and mark the value of the Poincaré index of the S1- or S2-wave at the point n, we get 2 regions with indices 1/2 and –1/2 separated by projection of the singular curve in the form of an ellipse or hyperbola. We compute equations for  of a degenerate ORT medium in terms of the values, , and velocity  of S1-, S2-waves on a singular curve. The singular curve is defined by the intersection of a unit sphere with an elliptic cone. It is proved that a degenerate ORT medium for  or  is, respectively, a transversally isotropic medium with a vertical or horizontal axis of symmetry. The results are illustrated in several examples.
Moisture as an indicator of the manifestation of hazardous properties of coal seams

Purpose: establish the change in the ratios between individual types of moisture and indicators of metamorphic transformations of coal seams after recalculating their values for the working state of the fuel. This will make it possible to predict the manifestation of hazardous properties mining.

Methodology: provides for the involvement of the initial experimental data that have been accumulated in normative and reference documents.

Results: When conducting research, the experience of using moisture as an indicator for solving three problems at once was taken into account: the criterion for evaluating the metamorphic transformations of coal seams; determination of fuel quality; forecast of the manifestation of hazardous properties of coal seams during mining operations. Different types of moisture at different stages of metamorphic transformations of coal seams are not equivalent in terms of the strength of the bond between water and coal. In some regulatory documents, in some cases, indicators of different types of moisture are used to characterize the moisture content of coal seams, which introduces additional errors in the reliability of the prediction of hazardous properties. In the early and middle stages of metamorphic transformations of coal seams, moisture is not formed for the most part, but only free moisture is mechanically removed from the system. Hard coals and anthracites have different molecular structure, which determines different ratios between the content of free and bound moisture. The content of total moisture is a metamorphic indicator only for organic (combustible) mass, and it is not a reliable criterion for assessing the transformation of coal seams in general. Mandatory pre-moistening of coal in the array in all cases during mining operations is not sufficiently substantiated for different stages of metamorphic transformations of coal seams due to the different ratio between the forms of moisture and the irreversibility of metamorphism processes.

Scientific novelty: for the first time, a quantitative assessment of the content of hydrated moisture in mineral impurities and moisture in the organic mass from the degree of metamorphic transformations of coal seams was made.

Practical value: the research results make it possible to develop proposals for improving the regulatory framework in terms of predicting the manifestation of hazardous properties of coal seams during mining operations, depending on the presence of different forms of moisture in coals.

Published: August 2022

The issue of covering the right to access information in the context of modern communicative practices in domestic science is one of the main theoretical and applied problems, because without its clarification at the level of research consciousness it is hardly possible to talk about a comprehensive study. Therefore, the aim of the article is to analyze the right to access information in the context of modern communicative practices in domestic science, as well as to clarify the role of research in the development of modern theory of social communications and the right to access information.

The methodological basis of the study is a set of philosophical and ideological approaches, general scientific and special legal methods.

The article analyzes the problems of the right to access information as a scientific foundation for the formation of ideas about access to information in the context of modern communicative practices in domestic science. Scientific views and discussions of leading scientists and researchers of this problem are considered. Attempts to understand the problem of access to information in the context of communicative practices in the field of law and in the context of historical, philosophical, socio-psychological, political science and technical research are highlighted. Scientific sources devoted to the problems of information and the right to access it in the light of the formation and development of communicative practices in the information society are studied.

The author found some inconsistencies in the views of scholars on the understanding of information in general as a category of social communications and communicative practices, the identification of the right to access information with the right to information. At the same time, a conclusion is made about the indisputable research value of the analyzed source base for further scientific research. It was found that scientific research of different periods of human development has not lost its significance, as a basis for the development of modern theory of social communications and the right to access information in the context of modern communication practices.
