Published: November 2023

Objectives: In this cross-sectional study we aim to assess the frequency of RVDD in chronic heart failure patients with reduced EF who visited as outpatient in a tertiary care hospital.

Methodology: We included consecutive patients with chronic heart failure who had reduced EF. We assessed these patients for RVDD if they had normal RV systolic function and pulmonary artery pressures. The RVDD was categorized as normal, impaired relaxation, pseudonormal filling and restricted filling according to ASE guideline. RVDD grades were compared with LV systolic dysfunction and diastolic dysfunction grades.

Results: Out of 199 patients evaluated, 66.3% (132) were male will with the mean age of 56.8 ± 12 years. The majority, 176, 88.4% of patients were with diagnosis if ICMP. The RVDD was noted in 112 (56.3%) patients out of which 30 (26.8%) had stage 1 (impaired relaxation) 78 (69.6%) had stage 2 (pseudonormal) and 4 (3.6%) patients had grade 3 (restrictive filling) RVDD. When compared a statistically significant association (P < 0.001) was observed between LV and RV diastolic dysfunction.

Conclusion: RVDD is under diagnosed entity of neglected ventricle which is significantly associated with LV systolic and diastolic dysfunction even if the RV systolic function is normal. The prognostic significance of this diastolic ventricular interaction needs to be further investigated.

Published: November 2023

Objectives: Acute myocardial infarction (AMI) stands as a global leading cause of mortality. Following AMI, meticulous management of patients' lipid profiles for secondary prevention becomes paramount. We conducted this study to assess lipid profile practices and levels in post-AMI patients, which are crucial for secondary prevention.

Methodology: In this cross-sectional study, we analyzed patients who had experienced their first AMI event in the past three years. We assessed fasting and non-fasting lipid profiles, reviewed statin therapy prescriptions, and examined patient compliance. The recommended dose was defined as rosuvastatin ≥20 mg or atorvastatin ≥40 mg, with target total cholesterol levels set at <160 mg/dL and target LDL (low-density lipoprotein) cholesterol at <55 mg/dL.

Results: Among 195 patients, 71.3% were male, and the mean age was 57.1±10.2 years. The median duration since AMI was 36 [IQR: 10-48] months and 60% were diagnosed with STEMI (ST-segment elevation myocardial infarction). Only 13.8% of patients were advised to undergo lipid profile testing after AMI, 88.7% of patients were on the recommended statin therapy, and 91.8% of patients were compliant with statin therapy. Only 11.5% had LDL-cholesterol within the target range and 71.7% had total cholesterol within the target range. Hospital admission in the past 12 months was reported by 14.4%, and the re-admission rate was significantly higher among non-compliant patients (37.5% vs. 5.6%). Subsequent AMI event rate was also significantly higher among non-compliant patients (43.8% vs. 11.7%).

Conclusion: Our study highlights that while most post-AMI patients receive the recommended minimum statin therapy, the inadequate practice of lipid assessment may compromise therapy optimization and raise the risk of subsequent events.

Estratégias para o ensino da fonética e fonologia portuguesa para hispanofalantes
Authors: Barbosa Keila Coelho
Published: November 2023

O objetivo deste artigo é analisar estratégias para o ensino da fonética e fonologia do português como língua estrangeira. Serviu por base um projeto realizado na Faculdade Coelho Neto, em Imperatriz, no Maranhão, onde participaram, nos meses de abril a junho de 2022, 16 alunos da Venezuela e Espanha. A metodologia utilizada tem caráter descritivo e exploratório, através de uma abordagem qualitativa para o ensino do português, com enfoque especial no contraste entre a língua materna dos alunos e o português. Isso abrange os sons específicos do português que são desafiadores para falantes de espanhol. Portanto, a partir das diversas pesquisas realizadas, conclui-se que as interferências ocorrem em graus variados devido à possível influência da interlíngua do aluno. Isso pode levar à adoção de uma pronúncia das vogais, tanto abertas quanto fechadas, além das possíveis dificuldades na produção dos sons de algumas consoantes. Tudo isso deve ser avaliado considerando o nível de proficiência linguística do aluno.

O que é normal? Um estudo qualitativo sobre a abordagem de queixas comportamentais na infância em programas de residência de medicina de família e comunidade de Minas Gerais.
Authors:   , Viveiros Luara Brandão
Published: November 2023

Este estudo investigou a abordagem de queixas de comportamento infantil e orientação parental em programas de residência em Medicina de Família e Comunidade de Minas Gerais. Queixas sobre o comportamento da criança e dificuldades em educar são comuns durante consultas médicas. Estudos demonstram que a vivência de situações psicossociais adversas traz desfechos negativos para a criança, para saúde física e mental, e que a parentalidade pode afetar diretamente a autoestima, regulação emocional e o bem estar. É importante que os profissionais de saúde estejam aptos a abordar o comportamento e a saúde mental na infância de forma eficaz e promover a interação saudável entre pais e filhos. O objetivo do estudo foi descrever e analisar as representações de preceptores e residentes de programas de residência em Medicina de Família e Comunidade de Minas Gerais sobre a abordagem de queixas de comportamento na infância e orientação parental. Trata-se de uma pesquisa de natureza qualitativa do tipo descritiva, conduzida a partir de entrevistas de aprofundamento com residentes e preceptores de três programas de residência em MFC do estado de Minas Gerais. Utilizou-se como referência roteiros semiestruturados de aprofundamento que continham uma situação de atendimento aos residentes e de ensino para os preceptores. O material foi codificado e categorizado segundo os princípios da análise temática de Braun e Clarke. A análise das entrevistas permitiu compreender que os entrevistados reconhecem que queixas sobre o comportamento infantil são demandas frequentes nas consultas de crianças na APS, e utilizam diversos procedimentos de avaliação e manejo para a abordagem dos casos. Entretanto, manifestam insegurança em relação ao diagnóstico do comportamento, e desejam conhecer algum referencial que auxilie na diferenciação do comportamento infantil normal de situações em que há transtorno. Os entrevistados que, por iniciativa própria, estudaram sobre parentalidade e conheciam algum referencial teórico sobre o tema não compartilhavam esta insegurança presente na maioria das entrevistas. Diante dos resultados e limitações da pesquisa, reconhece-se a necessidade de novos estudos sobre o tema, especialmente aprofundando na compreensão da insegurança dos profissionais diante das queixas de comportamento infantil. Além disso, evidencia-se a necessidade da inclusão da discussão sobre a abordagem do comportamento nas consultas de crianças no currículo formal dos programas de residência de medicina de família e comunidade, dada a relevância do treinamento para orientação parental como uma estratégia de abordagem familiar.

NUMERICAL ANALYSIS AND DIFFUSER VANE SHAPE OPTIMIZATION OF A RADIAL COMPRESSOR WITH THE OPEN-SOURCE SOFTWARE SU2
Authors: UZUNER Mustafa Kürşat , BAŞOL Altuğ , MISCHO Bob , JENNY Philipp
Published: November 2023

In recent years, the usage of open-source computational fluid dynamics tools is on a rise both in industry and academia. SU2 is one of these open-source tools. Unlike other open-source alternatives, SU2 is equipped with boundary condition types, solvers and methods that are especially developed for the analysis and design of turbomachinery. The aim of this work is to explore and investigate the capabilities of SU2 in the prediction of performance parameters of radial compressors. Two different single stage shrouded compressor geometries, one with a vaneless diffuser and the other with a vaned diffuser have been investigated with steady state CFD. The compressors were designed by MAN Energy Solutions Schweiz AG. Computational results with SU2 showed a satisfactory agreement with both the experimental data and reference CFD solutions obtained with Fidelity Flow, which is formerly known as Numeca Fine TURBO. Only at the relatively higher mass flow rates the difference between references and SU2 were higher compared to other operating points. After performance parameters were successfully calculated with SU2, the optimization tools that come with SU2 were also used. A 2D adjoint optimization study on the vane of the vaned diffuser was carried out. The study was carried out at a single operating point that is close to choke conditions. The loss generated by the large separated flow region at the suction side of the diffuser vane was reduced by 0.55 % in the optimized geometry using minimal modifications on the existing vane geometry to keep the performance of the compressor intact at other operating points. However, the resulting modification increased the total pressure loss by 0.86 % at one of the design operating points. This performance penalty could be due to the discontinuity in the vane geometry generated by the optimizer. Overall, the study shows that SU2 has the basic numerical schemes and models that are required for the analysis of radial turbomachinery flows and geometry optimization.

Published: November 2023

Várhegyi Éva könyve a széles közvélemény számára is közérthetően, de nagy szaktudással vezeti végig az olvasót azon a folyamaton, amelynek célja, hogy a 2010-et követően hatalomra kerülő Orbán-kormányok minél nagyobb befolyást szerezzenek a magyar bankrendszer felett. A könyv részletesen elemzi a folyamat lépéseit a bankszektor egyes szegmensei szerint sorra véve azokat. A Magyar Nemzeti Bank (MNB), a Magyar Fejlesztési Bank (MFB) és az Eximbank politikai „elfoglalásának” elemzése után azt mutatja be, hogyan került sor a magántulajdonú bankok feletti politikai befolyás következetes kiépítésére: Hogyan számolta fel a kormány előbb a takarékszövetkezeti szektort, hogy annak, valamint a Magyar Külkereskedelmi Bank (MKB) és a Budapest Bank (BB) bázisán létrehozza az OTP versenytársának szánt nagybankot, az MBH Bankot? Hogyan jutalmazta, illetve büntette a külföldi tulajdonban maradó bankokat, hogy „megszelídítse azokat”, illetve milyen az OTP-vel való, ellentmondásos viszonya? A könyv utolsó fejezetében, illetve a könyvet befejező zárógondolatokban pedig a korábban bemutatott tulajdonosi struktúra és működési rendszer által kiépített haveri rendszer sajátosságait és kockázatait veszi számba a szerző.
IoT-based intelligent system For Alzheimer's Disease Detection & Monitoring
Authors: Riad Mohamed
Published: November 2023

This research is based on two areas related to Alzheimer's disease, the first is the early detection and diagnosis of Alzheimer's disease using deep learning techniques and its various algorithms, and the second relates to how to monitor and follow up on Alzheimer's disease using the Internet of Things (IOT).

In this paper, a new diagnosis based on deep machine learning and monitoring of diseases similar to Alzheimer's is proposed. Diagnosis of Alzheimer's-like diseases is achieved through deep learning magnetic resonance imaging (MRI) analysis followed by an activity tracking framework to monitor people's activities in daily life using wearable inertial sensors. Activity monitoring provides a framework for assistance in activities of daily living and assessment of patient deterioration based on activity level.

The results of Alzheimer's diagnosis show an improvement of up to 86.34% with respect to current known techniques. Furthermore, greater than 95% accuracy was achieved for classifying activities of daily living, which is very encouraging in looking at the subject's activity profile.
Bi-Directional Hybrid Deep Learning model for Speaker Iden-tification
Authors: Lambamo Wondimu , Srinivasagan Ramasamy , Jifara Worku , Alzahrani Ali
Published: November 2023

Speaker identification is the process of automatically determining who is speaking from the known speakers by the model. It is crucial in voice-based authentication, forensic investigations, security and surveillance. In recent studies, the combination of convolutional neural network (CNN) and recurrent neural network (RNN) variants performed better than separate models of both. However, only limited studies are conducted in speaker identification using a combination of CNN and RNN variants. In this study, we proposed speaker identification using hybrid two-dimensional CNN (2DCNN) and bidirectional gated recurrent unit (BiGRU) to improve performance. The proposed model integrates the advantage of 2DCNN and BiGRU layers to improve the performance of the model. 2DCNN layers have the advantage of extracting short-term spatial features from input data and it has a limited number of parameters for computation. BiGRU layers have an advantage in extracting long-term temporal dependency between the features in both directions (i.e. backward and forward) and it is efficient in achieving convergence during training. Spectrograms of the speech were used as input in our proposed model because of the rich acoustic features of the speaker. To compare the performance of the proposed model, additional experiments are conducted using the models 2DCNN, CNN-LSTM, CNN-BiLSTM and CNN-GRU. The experiments were conducted on the VoxCeleb1 audio dataset, which consists of 153,516 utterances collected from the 1251 speakers. The accuracy, precision, recall and f1 score of the proposed model are 98.28%, 99.08%, 98.92% and 98.97% respectively. The proposed model was compared with the existing works to show the effectiveness of the proposed model. The experiment results and the comparison with the existing works show that the proposed model has higher performance than both existing works and other models experimented in this study.

Published: November 2023

Conservation and effective management of marine ecosystems and biodiversity requires accurate species identification. This study classifies sea bamboo (Isis hippuris) specimens using DNA barcoding, a technique widely recognized for its speed, accuracy, and objectivity. This study examines the cytochrome c oxidase subunit I (COI) gene analysis for species identification. Isis hippuris was collected from two stations (coral and seagrass areas) of Tanjung Tiram Waters, South Konawe, Southeast Sulawesi. Genomic DNA was extracted from the base, main, and lateral stem of I. hippuris. Polymerase chain reaction (PCR) was used to amplify the mtDNA of I. hippuris with HCO2198 and LCO1490 primers. The highest quality PCR product based on the COI gene was chosen for sequencing analysis. The study revealed that COI gene analysis could only be performed on the base and main stem of the I. hippuris. Samples from coral and seagrass-coral areas on lateral stems were not further analyzed due to low concentration and purity values, which could potentially fail DNA sequencing. Each part of I. hippuris may have unique genetic differences. This study highlights the advantages of DNA sequencing in providing a unique genetic fingerprint for each species, enabling accurate species identification. This research provides insight into using DNA barcoding for sea bamboo species identification.

Published: November 2023

The aim of this article is to present the practices of spatial and temporal organization and modes of inhabitation of multi-local researchers and to show how scientists perceive their multi-local lifestyle. Materials obtained from semi-structured, problem-oriented interviews, conducted as part of the preliminary research in 2022, were used for the analysis in the article. The research focused on four aspects: spatial arrangements and time use (duration and rhythm), multi-local practices (with particular emphasis on work-related mobility practices and housing arrangements), and the construction of the meaning of multi-local arrangements. The article attempts to contextualize the practices of multilocal life in accordance with the assumption that people living in several places constantly create new spaces, not only expressed in terms of real, territorial space but also socially or culturally constructed space.

The construction industry is experiencing immense pressure for substitutes for traditional building materials in the modern world. In the first half of 2020–2021, just under 57.93 percent of the total amount of fly ash generated in the nation was reused. The remaining material was thrown away of in landfills, spewing toxic substances into the immediate vicinity. Numerous creative proposals have been put forward all around the world that aim to increase the average amount of fly ash utilized during constructing. The most promising domains are geo polymer and high volume fly ash concrete construction. This study encompasses the research undertaken on each of these areas by an assortment of professionals internationally. Their attempts paid off, yielding concrete that exhibited barely any heat accumulation during its hydration process negligible sagging, enhanced versatility, and a modest dense utilizing a a great deal of ash from fly ashes. The outcomes derived from geo polymer concrete construction comprised outstanding durability, acidic obstructions, plus an elevated fly ash content, with characteristics analogous with that from Rcc constituents. Furthermore, the a project-specific strategy prescription is anticipated to be generated

LA ACEPTACIÓN DEL ACUERDO DE REPARTO DE DIVIDENDOS NO PUEDE FUNDAMENTAR UNA DERIVACIÓN DE RESPONSABILIDAD EX ART. 42.2.A) LGT: STS DE15 DE FEBRERO DE 2023, REC. NÚM. 3001/2021
Authors: Mercedes Navarro Egea
Published: November 2023

La derivación de responsabilidad prevista en el art. 42.2.a) de la Ley 58/2003 exige la prueba de la intención de colaborar en la ocultación de los bienes del deudor principal. La sentencia comentada proporciona criterios interpretativos útiles ante la posibilidad de que la Administración tributaria pretenda fundamentar la derivación de responsabilidad a un socio que ha aceptado el reparto de dividendos acordado por el órgano competente de la sociedad, con el argumento de que aquel no asistió a la reunión ni impugnó el acuerdo societario.
EL PAQUETE IVA EN LA ERA DIGITAL O «VIDA»
Authors: Gorka Echevarría Zubeldia
Published: November 2023

El 8 de diciembre de 2022, la Comisión Europea presentó un conjunto de propuestas conocidas como «IVA en la era digital (ViDA)» para modernizar el sistema de IVA de la UE. El objetivo es mejorar la eficiencia de la estructura del IVA de la UE para las empresas, al tiempo que refuerza su resiliencia frente a las actividades fraudulentas mediante la promoción de la digitalización. La Directiva propuesta abarca tres puntos focales principales («pilares»): 1. La expansión de la facturación electrónica y la introducción de obligaciones relacionadas con la información digital. 2. La introducción de un concepto centrado en un único registro de IVA para agilizar el proceso y mitigar la necesidad de múltiples registros locales dentro de los estados miembros. 3. Sobre la ampliación de la norma del proveedor asimilado a los mercados en línea dedicados al alquiler de alojamientos de corta duración o a la prestación de servicios de transporte de viajeros. Los contribuyentes deben de conocer estas normas para empezar a prepararse para los cambios radicales que se van a producir en materia de IVA en los años venideros.
LA DOCTRINA DEL TEAC SOBRE LA RESIDENCIA FISCAL DE LAS PERSONAS FÍSICAS
Authors: Abelardo Delgado Pacheco
Published: November 2023

El TEAC ha dictado en los primeros meses de 2023 varias importantes resoluciones en las que por vez primera construye una detallada doctrina sobre la interpretación de los criterios domésticos para la determinación de la residencia fiscal de una persona física. Ciertamente, esta doctrina nace con la limitación de no afrontar todavía la interpretación conjunta de estos criterios domésticos y de los contenidos en el artículo 4 del MCOCDE, en los supuestos de doble residencia. No obstante, la nueva doctrina del TEAC completa la contenida en una resolución anterior de 19 de diciembre de 2022 (04837/2019) y ofrece un detallado análisis del artículo 9 de la Ley del IRPF.
Límite temporal a los efectos derivados de la declaración de nulidad más allá de la litigiosidad bancaria: nulidad de los contratos de adquisición de derechos de aprovechamiento por turno
Authors: Benítez Rodríguez Daniel
Published: November 2023

Los procedimientos judiciales que tienen por objeto la nulidad contractual en diferentes sectores instados por consumidores son cada día más. Si bien la contratación bancaria se sitúa en cabeza, la contratación de productos vacacionales en forma de adquisición de derechos de aprovechamiento por turnos es relevante.Contratos celebrados muchos años atrás, en ocasiones hace más de 30 años, ven ahora cuestionada su validez. La normativa sectorial es tajante en relación con las consecuencias de la falta de cumplimiento de ciertos requisitos formales: la nulidad radical. En el ámbito bancario, son cada vez más los posicionamientos doctrinales y jurisprudenciales que limitan los efectos de la nulidad en el tiempo, a través de la institución de la prescripción. En estos momentos, y mientras no sea resuelta la cuestión prejudicial planteada por el Tribunal Supremo en fecha 22 de julio de 2021 y que ha dado lugar al asunto C-561/21 del Tribunal de Justicia de la Unión, el debate se cierne en torno al dies a quo.El presente artículo tiene por objeto analizar si los razonamientos habidos en el ámbito bancario son extensibles a la nulidad de los contratos de adquisición de derechos de aprovechamiento por turnos o, si por el contrario, una y otra nulidad y sus efectos son diferentes.

Published: November 2023

CAE (Computer-Aided Engineering) analysis is based on the sequence characteristics of the system, combining model reasoning to conduct analysis, the results have physical significance, is Know-Why but not the Know-How of traditional experience, thus it is possible to systematize and scientificize the injection molding parameter and design types for the order of state and product quality, achieving the goal of scientific injection molding (Scientific Molding). Due to the reliability of CAE results, it is possible to point out potential problems during injection molding and design, propose design modifications and possible solutions to obstacles and possible solutions, can avoid unsafed experience. CAE at the design stage can be performed on a computer for design modification options to conduct evaluation (Evaluate), evaluate (Verify) and optimize (Optimize), reducing time and cost mold testing, actual mold fixing, shortening actual trial and error cycle, shortening product development time and time-to-market, reducing waste, time and cost in stages. CAE can help injection molders predict and capture injection molding parameters for product quality impact, find out the processing direction (Processing Window) and optimize injection molding parameters. CAE can indicate the main factors affecting the quality of injection molding, thereby providing design modification parameters, injection molding parameters and quantitative criteria. In this article applied the CAE method to improve injection molding added the the best product. There are a lot of results: First of all, when making the mold, we will make the inserts to escape the air at the position of the cylinders. And the air outlet at the edge of the product so that the air at the edge can escape well; After improving the gate position, cooling water line, pressure protection, mold temperature, we see that the product has a change in warping, but it is not significant.

Authors: Duc Le Thanh
Published: November 2023

Bernoulli's law is widely used in practice and the study of fluid mechanics. This law has existed since 1738 when the Hydrodynamica book was published. Until now, it has not been repaired. The base of the law has some inaccuracies that lead to mistakes in its application. Therefore, their repair is essential. This article uses theories of physics and mathematical logic to point out the law's flaws. Current knowledge determines that the law of conservation of energy is correct. This correctness is the main basis for pointing out the problems in Bernoulli's law. The form of approach and problem-solving is to consider exercises and classic examples in textbooks on fluid mechanics. After that, they are going to be compared with the right knowledge. From it, the truths are reached. The study's main results pointed out Bernoulli's fundamental mistake, from applying basic knowledge to formulating the law. The errors of practical applications based on this knowledge are also clarified. From these results, there will be fundamental changes when building the theory for other sites. A series of applications in real life also change deeply. At the same time, they are leading to saving money, time, labor, and labor results and opening new doors of knowledge and science
