CASE REPORT OF PSEUDO-WELLENS’ SYNDROME AND MYOCARDIAL BRIDGING IN A YOUNG WOMAN
Authors: Kamcheva Mihailova Gordana , Nikolov Sasko , Jovev Marijan , Jordanova Slavica
Published: November 2022

The clinical entity in which Wellens' electrocardiographic changes occur in normal coronary arteriesconfirmed by angiography is defined as Pseudo Wellens syndrome. Myocardial bridging is a condition wheremuscle fibers abnormally bridge the intramyocardial passage of an epicardial coronary artery, which subsequentlybecomes a tunneled pathway beneath them. It is most commonly found in the middle segment of the left anteriordescending artery (LAD) (70% to 90% of cases). It is recognized as the most common congenital coronary anomaly.Case report: A 49-year-old woman came to the emergency room because of tightness in her chest that she had a fewmonths ago, but today is more pronounced. After consultation, she was hospitalized at the cardiology department forfurther treatment and investigation. An electrocardiogram showed sinus rhythm with inverted T waves in precordialleads V2 to V5. She underwent distal transradial coronary angiography on the same day, which revealed mid-LADsegment systolic compression (10 mm) consistent with myocardial bypass.The clinician should be aware of MB as a potential cause of pseudo-Wellens syndrome and in the differentialdiagnosis of inverted T waves in a young subpopulation at presentation of acute coronary syndrome.

Authors: Mitrović Nebojša , Stević Dalibor
Published: November 2022

The frequency of occurrence of acquired flat feet increases with the development of civilization, becausethe gripping function has completely disappeared and today the foot is exclusively used for support. The correctshape and function of the foot directly depends on a properly built bone structure and a good balance of the strengthof the muscles involved in standing and walking. If this balance is disturbed, as a result, the vaults descend. The aimof the work was to analyze the prevalence of lowered foot arches in boys and girls aged 6 to 11 from Bijeljina andBrčko (Bosnia and Herzegovina). The research was transversal in nature, only one measurement was carried out.235 children of both sexes, 111 boys and 124 girls, took part in the analysis of the arches of the feet. The diagnosisof flat feet is based on the valgus position of the heel and the lowered arches of the feet. The subjects' feet werescanned in a standing position with a computer digital podoscope SupOrt. This measuring instrument analyzes thestatus of the arch of the foot in 5 degrees, four degrees refer to a flat foot and one to the so-called indented foot. Theresearch results show a high prevalence of lowered foot arches in the analyzed sample of respondents of 63%. Malerespondents had a significantly higher prevalence of lowered foot arches compared to female respondents. Thisresearch is one of the few that uses a reliable digital computer podoscope to analyze the arches of the feet. Childrenwith increased body mass had a higher prevalence of foot deformities.
RESEARCH ON THE INFLUENCE OF DIFFERENT TYPES OF ANION-EXCHANGE CARTRIDGES ON THE QUALITY OF [18F]NAF RADIOPHARMACEUTICAL AS PART OF PRODUCTION PROCESS DEVELOPMENT
Authors: Atanasova Lazareva Marija , Ugrinska Ana , Janevik-Ivanovska Emilija
Published: November 2022

[18F]Sodium Fluoride radiopharmaceutical is a sterile solution for intravenous administration, intendedfor skeletal visualization by positron emission tomography (PET). [18F]Sodium Fluoride for bone imaging wasintroduced in early 1960's, but with the increased availability of PET scanners in the last two decades, thisradiopharmaceutical has growing use in clinical practice for the detection of bone metastases. The productionprocess of [18F]NaF includes production of the radioisotope [18F]F- and purification and formulation of the [18F]NaFradiopharmaceutical. The radioisotope [18F]F- is produced by a cyclotron via the 18O(p,n)18F nuclear reaction,followed by recovery of [18F]F- from [18O] proton-irradiated water by adsorption and desorption from anionexchangeresins. The fluoride anions are trapped on the anion-exchange SPE (solid-phase extraction) cartridge, andall other cationic and water-soluble radionuclide impurities present in irradiated enriched water are collected in thewaste vial. Next step is desorption of the fluoride anions from the cartridge by elution with saline solution (0.9%NaCl). This study aimed to define the most appropriate type of anion-exchange SPE cartridge which could be usedfor routine production [18F]Sodium fluoride radiopharmaceutical which meets the quality requirements defined inEuropean pharmacopeia monograph. For that purpose, as part of development of in-house production method,manual productions with four different types of anion-exchange cartridges were performed. The influence of sorbentsubstrate and counter-ion of the cartridge on the final yield and the quality of the produced radiopharmaceutical wasinvestigated. The study also aimed to define the minimum volume of physiological solution required for the pHparameter to be within limits.The results have shown that the quality parameters: appearance, chemical purity, radiochemical purity andradionuclide purity were in defined acceptance criteria and did not differ when using different anion-exchangecartridges. The pH analyses have demonstrated that the type of cartridge and counter-ion influence the final pH of[18F]NaF solution. This study confirmed that the three types of anion-exchange resins (QMA-Cl-, QMA-CO32- andPS-OH-) could be used for production. In the experiments where QMA-Cl- was used, the required pH level wasobtained even without dilution. The other cartridges could be used in the [18F]NaF production process, but furtherdilution is necessary in order to obtain the pH value in acceptance criteria. On the basis of this study, the QMA-Cl- ischosen as a cartridge to be used in the further development of the in-house method for [18F]NaF radiopharmaceuticalproduction.
SYNTHESIS AND CONVERSION OF NEW POTENTIALLY BIOLOGICALLY ACTIVE 4-THIAZOLIDINONE DERIVATIVES WITH A TRIAZINOINDOLE FRAGMENT IN THE MOLECULES
Authors: Harkov Stefan
Published: November 2022

A wide spectrum of biological activity and the possibility of diverse chemical modification of isatinderivatives prompts the search for new highly active compounds as potential drugs among condensed and noncondensedheterocyclic systems containing the specified molecular "matrix". Studies of 1,2,4-triazino[5,6-b]indoles,the chemical precursors of which are isatins, have shown the prospect of their use in the treatment of oncologicaldiseases. In addition, potential antifungal, antiviral, antihypertensive agents have been identified among thesederivatives.Adhering to the main synthetic strategy of our research, which is based on the "hybrid-pharmacophoric" approach inthe synthesis of new heterocyclic derivatives of 4-thiazolidinone, in our opinion, the combination of the mainscaffold (4-thiazolidinone) and the structural "imitator" is interesting and promising of the isatin "matrix" -triazinoindole fragment, as well as the synthesis of new polyheterocyclic ensembles, including those with apharmacologically attractive pyrazoline fragment. Under the conditions of the S-alkylation reaction of 3-mercapto-5H-1,2,4-triazino[5,6-b]indoles, 2-chloro-1-(3,5-diaryl-4,5-dihydropyrazole- 1-yl)ethanones, which made it possibleto obtain 1,2,4-triazino[5,6-b]indole-pyrazolines with preparative yields. By hydrazinolysis of 3-mercapto-5H-1,2,4-triazino[5,6-b]indoles, corresponding hydrazines were obtained, which were successfully used for the first time inthe Holmberg reaction, and derivatives of the triazinoindole-thiazolidinone system were obtained – 3-(1,2 ,4-triazino[5,6-b]indol-3-ylamino-2-thioxothiazolidin-4-ones Chemical modification of methylene-active compoundswas carried out under the conditions of the Kniovenagel reaction with aromatic aldehydes and isatin derivatives,which was substantiated by the results of biological studies of structurally related heteryl-substituted 5-ylidenerhodanines. The synthesis of derivatives of the 4-thiazolidinone-thiadiazinoindole system, which is based onthe interaction of N-(1,3,4-thiadiazinoindol-2-yl)-2-chloroacetamides with ammonium thiocyanate in an acetonemedium, was carried out. The obtained conjugates are methylene-active compounds, which made it possible tosynthesize a series of 5-arylidene derivatives under the conditions of the Kniovenagel reaction. The purpose of thework is to experimentally confirm or refute the feasibility of chemical modification of isatin into the triazineindolinesystem and its combination with 4-thiazolidinone biophore for the search of new biologically activecompounds, including highly active antitumor agents. The structure of the synthesized compounds was confirmedby NMR spectroscopy. To study the structure in the solid state, the IR spectra of the key compounds in KBr tabletswere studied.
PROFESSIONAL COMPETENCES AND CONTENT OF THE UNDEGRADUATE PUBLIC HEALTH PROGRAMMES IN EUROPE
Authors: Aleksandrova Valentina , Dokova Klara
Published: November 2022

Sufficient number of competent public health professionals are an important prerequisit for the normalfunctioning of the health systems. At present, the number and type of institutions carrying out undergraduate educationand training in public health varies broadly both in Europe and the USA. There is a lack of clarity on how much therequirements for professional public health competencies are covered by the content of undergraduate public healthprograms in Europe. Purpose: To analyse the content of Bachelor Public Health programmes in Europe, in relation tothe requirements for professional competences introduced by ASPHER in 2014 (Association of Schools of PublicHealth in the European Region). Methods: An online questionnaire was developed and distributed via the Internetplatform Google Forms to 214 universities in Europe. The electronic survey included 50 questions clarifyingavailability of study subjects and topics from 7 main areas of competences proposed by ASPHER: Methods in PublicHealth; Population Health and Determinants; Health Policy; Economics and Management; Health Education andHealth Promotion; Interdisciplinary subjects; Practical Training and Others. Similar information was extracted from theeducational documentation accessible from the web pages of 74 higher educational institutions offering undergraduateprograms in public health from 19 European countries. Results: Information for 59 undergraduate public healthprogrammes was retrieved, 45 from west and 14 from east Europe. Subjects related to “Health Inequalities”, “GlobalHealth”, “Information Technologies”, “Ageing”, “Leadership”, “Genomics” are available in less than 50% of theprogrammes in both west and east Europe. There is a clear difference between west and east programmes in someaspects. In the central focus of training in PH in Bulgaria and the countries from Eastern Europe are the specializedprevention disciplines related to hygiene and epidemiology of communicable diseases and a considerable number ofclinical disciplines. The latter are less presented in the training in Western European programmes, which are moreoriented towards health policy and management. Conclusions: There is a significant variation in the content and as aresult the professional competences provided by the undergraduate PH education programmes in Europe. Both westand east European undergraduate PH programmes fail to address adequately the present global challenges in the areastarting with existing health inequalities. Recommendation: There is an urgent need for regulation of public health as abasic regulated health profession in the European Union, which will entail standardization of the content of thebachelor education and will stimulate the recognition and the importance of the profession across Europe as well.

Authors: Salkić Naim , Povlakić Hadžiefendić Meliha
Published: November 2022

Writing is an integral part of linguistic education of deaf persons which, due to the lack of auditorysensors, has an insurmountable difficulty achieving, so this shortcoming is directly reflected in the general literacyof deaf children. Many detailed studies in the world suggest that in order to become literate, a deaf child must learnthe language of the community. Je/she must first learn the letters and learn to write. About 50% of young deafpeople after high school read and write worse than a ten-year-old hearing child. The aim of this research is toexamine the usage, reading, writing, and comprehension in deaf children of the adverbial clause of place in writtenform and to determine the statistical significance of differences between deaf and hearing children. The study wasconducted on a sample of 140 respondents. The first subsample of subjects, the experimental group consisted of 70deaf students, and the second subsample, a control group of 70 hearing students, of the same chronological age. Themeasurement instrument “Test of writing, and comprehension of an adverbial clause of place” was applied. Thefrequencies and percentages of respondents' responses to the variables were calculated. The F (Fisher) test was usedto determine the statistical significance of the differences between deaf and hearing subjects. The results showed that1.40 % of deaf children are completely successful in reading and writing priloske odredbe, and thaat 90 % of deafchildren use prislocke odredbe partially successfully. The percentage of children that do not use priloske odredbe inany form in their written communication is 8.60%. The order of use of adverbial clause of place by frequency is asfollows: "in", "on", "below", "behind", "next to", and "between". The largest number of deaf children use theadverbial clause of place "in" in their written expression, 65.70% of them. Then, the adverbial clause of place "on"51.14%, the adverbial clause of place "below" 47.14%, the adverbial clause of place "behind" 31.43%, the adverbialclause of place "beside" 30%, and the adverbial clause of place "between" 22.85%.There is a statistically significant difference between deaf and hearing children in the use of the adverbial clause ofplace at the level of statistical significance of p=0.000.

Published: November 2022

Las siembras de trigo (Triticum aestivum L.) de temporal en México durante los últimos 15 años se incrementaron de aproximadamente 120 mil hectáreas, entre otras causas, debido a las ventajas que ha mostrado este cereal sobre cultivos tradicionales como frijol (Phaseolus vulgaris L.) y maíz (Zea mays L.). Así mismo, se vislumbra, de acuerdo con estudios sobre potencial productivo realizados por el INIFAP (Instituto Nacional de Investigaciones Agrícolas y Pecuarias), que en el país puede cultivarse bajo temporal cerca de un millón de hectáreas con trigo, situación ante la cual las variedades mejoradas deben ser un componente tecnológico importante para hacer frente a la compleja problemática biótica y abiótica que incide en este cereal cultivado en los diferentes estados productores de la república.
Manifestaciones del catolicismo sobre el surgimiento de las universidades privadas. Las miradas de las revistas Criterio, Estudios, y Sapientia entre 1956 y 1958
Authors: Fabian Jorge Luis
Published: November 2022

A pesar de que existen diversas publicaciones sobre el surgimiento de las universidades privadas en nuestro país, en el campo de la Historia de la Educación Argentina no se han realizado muchos análisis que se centren en la mirada de la Iglesia católica y sus fieles sobre este acontecimiento. En líneas generales, se ha trabajado el tema desde perspectivas vinculadas al estudio de las universidades nacionales o al contexto socio-político. Es por este motivo, que pretendemos indagar y reflexionar sobre los discursos de diferentes sectores del catolicismo que proponían la creación de “universidades libres” sosteniendo como principal argumento la necesidad de lograr un real cumplimiento del principio de libertad de enseñanza. Teniendo esto en consideración, nos situamos desde la perspectiva teórica de la Historia de la Educación, y proponemos realizar un análisis cualitativo de los artículos publicados en las revistas católicas Criterio, Estudios y Sapientia, sobre los acontecimientos que sucedieron durante el período transcurrido entre la firma del decreto ley que posibilitó el surgimiento de las nuevas instituciones en diciembre de 1955 y la asunción del gobierno democrático de Arturo Frondizi en mayo de 1958.
História e memória de professor. A docencia masculina na infância
Authors: Faria Adriana Horta de , Sarat Magda
Published: November 2022

No Brasil, a atuação docente com crianças, tem sido atribuída majoritariamente às mulheres, devido a concepções históricas associando características femininas à maternidade, portanto, abnegação, paciência, docilidade, seriam adequadas na educação das crianças. Homens lecionando para crianças são mais raros e, vistos por mui- tos como inadequados para a tarefa, pois representariam adjetivos como: força, rigidez, dureza, entre outros. Partindo, dessas con- cepções, nossa pesquisa buscou elucidar a participação masculina na história da docência com crianças a partir das memórias de 3 professores homens, considerando que seus conhecimento e trajetória podem inspirar e estimular novos docentes, contribuir com a história da prática educativa e discutir os estereótipos de gênero na profissão. Para tanto, utilizamos a História Oral Temática, seguindoseus procedimentos metodológicos e trabalhando com as memórias dos professores acerca do tempo quando exerceram a prática docente. Tais relatos permitiram analisar a docência pautado em inferências de gênero, pois, segundo os entrevistados, por serem do sexo masculino e carregarem atributos de gênero como força, coragem e ousadia puderam desempenhar melhor o trabalho nas escolas de áreas rurais. Nessas escolas rurais tiveram que enfrentar problemas geográficos, intempéries, longas distâncias e outras dificuldades do ambiente rural. A partir dos relatos destes professores, os dados nos informam que eles “venceram os desafios” ao atuar em uma profissão histórica e sexo tipificada como feminina.Mas destacaram a vigilância dos pais e familiares, e o desafio de continuamente ter que provar sua competência e ainda angariar a confiança familiar.

Los colegios nacionales y las escuelas normales a fines del siglo XIX
Authors: Duarte Oscar Daniel
Published: November 2022

Los colegios nacionales han sido en la Argentina las instituciones de formación de la élite dirigente, de los funcionarios estatales, a la vez que preparatorios para el ingreso a la Universidad. Esto ha conducido a que la historiografía realce el carácter elitista de los mismos sin percibir en su justa dimensión sus alcances en cuanto a matrícula y sus mecanismos selectivos internos. Tampoco se ha comparado, en términos estadísticos, su desarrollo con respecto a las escuelas normales, siendo ambas modalidades las principales de la educación posprimaria. Este artículo se aboca a describir los avances y limitaciones de estas instituciones, tomando como eje la matriculación, deserción y egreso de los estudiantes. Se han empleado como fuentes principales las estadísticas oficiales, con las cuales se reconstruye el cuadro de situación de la educación secundaria en las coyunturas analizadas. Además, se explora la inserción laboral de los graduados.

Published: November 2022

El artículo presenta una investigación que tiene como objetivo general analizar los principales impactos educativos experimentados en la Universidad Nacional de Río Cuarto a partir de la pandemia por COVID-19, desde la perspectiva de los estudiantes y desde un enfoque de derechos. Se llevó a cabo una investigación cualitativa con un enfoque interpretativo, realizando entrevistas semiestructuradas a estudiantes efectivos. Para el análisis del material  se realizó un proceso de categorización basada en los mismos. Los testimonios de  los estudiantes dan cuenta de impactos, en el sentido de huellas, cambios o reconfiguraciones en las relaciones entre sujetos, institución, tecnologías y contextos, con relación a trescategorías analíticas: (a) los procesos de inclusión-exclusión emergentes; (b) “esto no es la universidad”;  (c) cambios en las prácticas de enseñanza y aprendizaje, en particular en las interacciones con los profesores y con los estudiantes, la formación práctica, las formas de evaluación, las disposiciones de los docentes y la autonomía de los estudiantes.
Devenir del trayecto de la práctica en entornos virtuales de los profesorados universitarios en matemática
Authors: Sgreccia Natalia Fátima , Ciccioli Virginia , Mengarelli María Sol
Published: November 2022

En el presente artículo se comparten reflexiones acerca de la re-configuración de las instancias de formación para la práctica docente en Matemática en el año 2020. Se considera el conjunto de los Profesorados Universitarios en Matemática de las Universidades estatales de Argentina (que ascienden a 30), contando con el testimonio de las dos terceras partes de los mismos. Los asuntos de interés giran en torno al reconocimiento de similitudes, así como diferencias con respecto al aula presencial, contemplando lo social, lo tecnológico, lo institucional y el contenido en tratamiento. También se señalan dificultades que se han tenido en este contexto y, al mismo tiempo, se identifican aspectos que se considera que se están potenciando, con respecto a lo que suele suceder en el aula presencial. Finalmente, con foco en el proceso de virtualización, se comparten limitaciones y posibilidades para el entramado del trayecto en cuestión. Se efectúa un análisis de contenido de las respuestas, a partir del cual es posible advertir un panorama muy heterogéneo y diverso de lecturas en clave de oportunidad o de resignación. De este modo, en cuanto al devenir en cuestión, se concluye que este proceso ha conllevado a interpelar el aula de formación y re-dimensionarla hacia esquemas híbridos de aula invertida que mixturen los formatos habituales con los nuevos emergentes.
Ciudadanías, derecho a la educación y pandemia: relatos y producciones de estudiantes en contextos de precaridad urbana
Authors: Minchala Carlos , Langer Eduardo
Published: November 2022

El artículo tiene como objetivo describir las formas que adopta la ciudadanía en el marco de la pandemia atendiendo a las disputas por el derecho a la educación de estudiantes del nivel secundario que viven en contextos de precaridad del Partido de San Martín. La hipótesis que se propone desarrollar es que con el advenimiento del COVID-19, los/as estudiantes agudizan sus demandas relacionadas con las condiciones materiales de las escuelas y la transmisión de saberes, a la vez que producen otras vinculadas con el acceso a la tecnología y la conectividad para sostener sus escolaridades. Ellos/as vivencian sus ciudadanías como reclamos, ya que sus prácticas discursivas (Foucault, 1968) dan cuenta de que el derecho a la educación está en disputa debido a las escasas condiciones materiales y tecnológicas, así como por las dificultades que encuentran para lograr sus aprendizajes. Para ello, aquí se trabajarán con registros de imágenes, así como con producciones escritas y audiovisuales de estudiantes en el marco de una actividad de extensión universitaria durante 2019 y 2020. Algunos de los resultados muestran que el acto de enunciar y denunciar las problemáticas que afectan a nivel personal, social y educativo, así como el sentido de la solidaridad y organización social de los individuos son características centrales en la configuración de las prácticas de ciudadanía en los barrios populares.
Storyboard de la escolaridad en tiempos de pandemia: efectos y regulaciones en el trabajo pedagógico remoto
Authors: Villagran Carla Andrea
Published: November 2022

La pandemia por COVID-19 irrumpió la previsualización de las acciones propias del trabajo pedagógico tanto a nivel de las agencias oficiales como, especialmente, de las escuelas y elprofesorado. Los tiempos escolares y domésticos se vieron “estallados” y superpuestos, desarmando el storyboard inicial. La pandemia y la virtualización compulsiva de la enseñanza y el aprendizaje producen otras formas de regulación de los tiempos y espacios escolares y del trabajo pedagógico remoto con gran acento en el control y la experimentación.Este artículo presenta resultados de investigación en torno a los efectos de la pandemia en la escolaridad y, específicamente, en el trabajo pedagógico y las subjetividades del profesorado. Tal como Deleuze (2015) señala, las subjetividades son memoria y no son unívocas sino que se producen en múltiples instancias individuales, colectivas e institucionales. En este sentido, nos interesa recuperar un nivel descriptivo, desde la perspectiva de las instituciones y del profesorado, acerca de cómo vivieron el shock de la pandemia (Grinberg, Verón, & Bussi, 2020) y la virtualización de la enseñanza. Proponemos entonces, bosquejar un storyboard de la escolaridad que continuamente lucha con la tiranía de los tiempos superpuestos y la incertidumbre de una pandemia a nivel global. Una de las pocas certezas en estos tiempos aciagos es que —una vez más— la escuela responde, se sostiene y resguarda el lazo social.

Authors: Peña Cobeñas Dagoberto Carlos
Published: November 2022

Usando data mensual del periodo enero 2012-febrero 2022 y un modelo autorregresivo de retardo distribuido con el posterior mecanismo de corrección del error, este estudio estima las elasticidades precio e ingreso de las exportaciones e importaciones reales en el Perú, considerando a Estados Unidos como el socio comercial de referencia. Los resultados revelan que: (i) únicamente el flujo de exportación real (total, tradicional y no tradicional) aumenta significativamente durante la crisis Covid-19 (marzo 2020-febrero 2022); (ii) la elasticidad ingreso del comercio real es positiva en el corto plazo, y negativa en la mayoría de flujos a largo plazo. Sin embargo, no se registra un consenso para la elasticidad precio; (iii) existe una relación bidireccional en el comercio real, generándose mayor exportación vía la importación de bienes de consumo, insumos y bienes de capital.
The Relationship between Knowledge and Skills of Nurses and Triage Measures in the Emergency Room (Igd) of the Islam Malahayati Hospital in Medan in 2022
Authors: Syamsul Idris
Published: November 2022

Data on patient visits to the emergency room around the world has increased from year to year where 50% of them are visits with non-urgent conditions. In Indonesia, the data on patient visits to the ER is 4,402,205 patients (13.3%) of the total of all visits at the General Hospital, where this makes nurses have to sort out patients quickly and precisely according to priorities. To support this, knowledge and skills are needed to minimize the separation of types and emergencies of patients in triage, so that the treatment carried out is more optimal. The aim of the study was to determine the relationship between knowledge and skills of nurses and triage measures. Triage is a way to select or sort victims based on their level of emergency. This type of research is Correlation Researchwith a quantitative cross sectional research design. The population in this study were all nurses in the Emergency Room at the Malahayati Islamic Hospital in Medan. The sampling technique is saturated sample, with a total sample of 14 nurses. The instrument in this study was a questionnaire consisting of a questionnaire on nurses' knowledge about triage and nurse skills.The research instrument uses an observation sheet. Bivariate analysis with Chi square test. The research results show thatthere is a relationship between nurse knowledge and nurse skills with triage measures with a p-value coefficient of 0.03 <0.05, which means Ho is rejected and Ha is accepted. The conclusion is that there are 11 (78.6%) respondents who have a moderate level of knowledge with a ready skill level in the Emergency Room of the Islam Malahayati Hospital, Medan. From this study it is suggested that nurses always increase their knowledge, especially about triage.

Published: November 2022

This article shows the mathematical development to determine the length and cycle time of a furnace that is used for heating parts in the hot forming process. The input parameters, the required production capacity and the temperature to reach the austenite phase in the material were used. For the mathematical process, it was necessary to know the stages for the process, considering that there are two methods: the direct and indirect process. Subsequently, the number of annual pieces that should be produced per year was determined, thereby being able to conclude the cycle time that should be estimated for the furnace; Likewise, some thermal parameters that the oven must have were known, such as the internal temperature, which helped to know its length, in order to meet the demands of the production volume. This work aims to present alternatives to the industries dedicated to the stamping process, specifically hot forming stamping, based on the analysis of the selection of the heating equipment, based on the production needs.
Analysis and dynamic simulation of the cardan shaft for the minilow prototype vehicle
Authors: Aguilar-Moreno Antonio Alberto , García-Duarte Oscar Enrique , Arellano-Patiño José Antonio , Álvarez-García Eduardo
Published: November 2022

This article shows the finite element analysis for the simulation of dynamic loads to two prototype models of cardan shafts considering two types of material, alloy steel and 1045 steel, to determine the structural efficiency of work, by means of contour conditions extracted from two types of engines raised for a minilow vehicle. In order to perform the structural simulation of dynamic loads, it was essential to simulate motion analysis and determine that both models do not present some gap or energy irregularity. This consisted in obtaining the dynamic results (displacement and angular speed, torque and power), comparing them with those indicated by the manufacturer of each engine. The finite element analysis was then performed for the structural simulation of dynamic loads, identifying the element that generates the minimum Von Mises forces, the lowest unit displacement and the minimum safety factor. The aim of this work is to confirm whether the two models comply with the structural analysis of dynamic loads and, based on this, to select the one with the most favorable results to work on the transmission of a minilow car.

Abstract: Hyperbilirubinemia is frequently found in newborns, especially in low birth weight (LBW) infants (less than 2,500 g). Hyperbilirubinemia is an increase in bilirubin higher than 5 mg/dL which clinically manifests as icterus. This study aimed to evaluate the relationship between LBW and the incidence of hyperbilirubinemia as well as the underlying mechanism. This was a literature study. Article searching used databases of Pubmed and Google Schoolar and the keywords were Hyperbilirubinemia AND Low birth weight NAD Neonatal Jaundice. The results showed a relationship between LBW and the incidence of hyperbilirubinemia. There were increases of hemoglobin, heme catabolism, and destruction of bilirubin due to liver immaturity, impaired liver function and perfusion and bilirubin conjugation ability, less of albumin as the transportation protein and uridine diphosphate glucuronyltransferase (UDP-GT) to convert indirect bilirubin to direct bilirubin in the liver. In conclusion, there is a relationship between low birth weight and hyperbilirubinemia that occurs due to liver immaturity, impaired liver function and perfusion, and less of albumin and UDP-GT enzyme.Keywords: hyperbilirubinemia; low birth weight; neonatal jaundice Abstrak: Hiperbilirubinemia merupakan masalah yang sering terjadi pada bayi baru lahir terlebih bayi dengan berat lahir rendah (<2.500 gram).

The active introduction of additive technologies in many industries, including agriculture, determines the relevance of studying the properties of materials used in printing and the characteristics of the resulting products. Polymeric materials are widely used in 3D printing, which can be used to create new composites with the required parameters. One of the approaches to significantly improve the properties of parts made of polymers obtained using 3D printing is their metallization. The article proposes a technology for surface hardening of parts made of thermoplastic polymer materials. This technology is based on combining the action of an external heat flux, which is directed to the hardened surface, and a magnetic field, acting from the opposite surface of the part. Under the influence of magnetic and thermal fields, diffusion of metal powder particles into the polymer surface occurs. In particular, the hardening of the impeller blade of a liquid ring vacuum pump made of ABS plastic by means of three-dimensional printing using FDM technology is considered. The characteristics of the used thermoplastic polymer, which affect the regime parameters of the printing process and subsequent hardening, are considered. The developed installation is described, by means of which magnetothermal reinforcement is carried out. The following surface hardening parameters are possible: molding pressure 2 MPa; preheating the mold to 160-180℃ (approximately 20℃ lower than the melting point of ABS plastic); exposure at the specified temperature and pressure for no more than 2 minutes, followed by cooling in air. Nickel powder with a particle size of 40 μm was chosen as a ferromagnet for hardening. In the future, it is possible to conduct research on the introduction of metal powder into the product during the printing process.

As a result of the analysis of the state of the issue of increasing the efficiency of the use of machinery and extending the service life in agricultural enterprises, it was determined that the refusal of the operation of flushing the lubrication system after replacing the engine oil that has expired reduces the operational characteristics of diesel engines of tractors, the service life of freshly refilled oil decreases. It was established in the course of modeling the process of flushing oil channels that commercial oil M10G2 does not fully ensure the removal of contaminants from the system compared to special flushing oils. Thus, as a result of preliminary experimental studies, it was found that at a pressure of 4 kg / cm2, the content of insoluble precipitate in M-10G2 oil decreases by 0.1-0.2%. As the pressure increases to 8 kg / cm2, these indicators improve. One of the tasks of increasing the efficiency of flushing the lubrication system is to reduce the cost of improving this operation. In this regard, it was decided to use the engine oil that has been used for its life as a washing oil. In laboratory conditions, the possibility of removing contamination from the waste oil was considered. For these purposes, coagulants were introduced into the heated oil and an oil purification operation was carried out in a laboratory centrifuge. After that, the washing properties of the M-10G2 oil of the Volga brand washing oil and purified waste oil were evaluated, which allowed to establish sufficiently high washing properties of commercial oil and purified used engine oil. The possibility of cleaning the lubrication system with used engine oil without draining it from the engine crankcase is considered. It was found that the introduction of a 2% mass solution of urea in ammonium hydroxide into the crankcase of the engine makes it possible to enlarge the contamination particles with their subsequent removal by a centrifuge built into the lubrication system. The thickness of the sediment layer on the walls of the centrifuge for 30 minutes of engine operation on oil with additives was 20 mm, while for a period of 200 hours it was 15 minutes. The color of the oil in CST units has changed from 7 to 3.5.

Abstract: Purpose: The COVID-19 pandemic has had a negative impact on physical and mental health. During this pandemic, there has been an increase in stress and anxiety in individuals who experience it. Individuals who are susceptible to stress and anxiety, one of which is pregnant women. Maternal compliance in undergoing antenatal care is one of the efforts made to determine the health of the mother and fetus during pregnancy. This pandemic is one of the reasons that make pregnant women delay starting ANC services. Based on the background of the problem, this study was conducted to find out whether there is a relationship between the level of anxiety of pregnant women during the COVID-19 pandemic with compliance with ANC at the Cipadang Village Health Center, Pesawaran Regency. Method: This study uses an observational analytic method with a cross sectional approach. Respondents were taken using total sampling technique. The data used in this study is primary data. The independent variable in this study was the level of anxiety which was assessed using the Hamilton Anxiety Rating Scale. The dependent variable of this study is the number of ANC visits obtained through the MCH book. Results: A total of 54 pregnant women with an age range of 19-42 years, a minimum score of 0 and a maximum score of 36, the number of ANC visits at least 1 time and a maximum of 16 ANC visits. The results showed that there were 6 pregnant women (11.1%) working with a junior high school education level of 22 people (40.7%). A total of 40 (74.1%) pregnant women were multigravida. The number of ANC visits was found to be the same in each group with complete and incomplete ANC visits, with an anxiety level of 36 people (66.7%). p-value is 0.013 so that there is a significant relationship between anxiety levels and ANC compliance. Limitations: The number of subjects involved in the study was still small and subjects were not involved in each trimester. Contribution: The results of this study are expected to provide information about the importance of ANC and maintain mental health for pregnant women and be input for health agencies to pay more attention to anxiety management education related to concerns of pregnant women in conducting ANC visits during the COVID-19 pandemic.
