Authors: Nguyen Van Que , Dung Hoang Tien , Nguyen Van Thien , Pham Van Dong , Nguyen Van Canh
Published: April 2023

In this study, the multi-objective optimization method for thin-wall milling of 6061 aluminum alloy is addressed. The technological parameters including the cutting speed Vc, the feed of tooth fz, and the width of cut ar are considered input variables, while the manufacturing responses are surface roughness Ra, production rate MRR, and flatness deviation FL. The goal is to find the optimum cutting parameters to minimize Ra and FL and maximize MRR, at the same time. To solve this problem, the desirability function approach was used based on Taguchi orthogonal array. Twenty-seven experiments were conducted and the measured data were collected. The mathematical regression models for responses Ra, MRR, and FL were then generated and evaluated by using the analysis of variance method. Then, the multiple objective optimization problems were solved by using the desirability function approach. The optimum cutting parameters set are Vc=120m/min, fz=0.06mm, and ar=0.13131mm, corresponding to Ra=0.1613µm, MRR=17197.45cm3/min, and FL=0.0995mm.
Expanding the Data Normalization Strategy to the MACONT Method for Multi-Criteria Decision Making
Authors: Nguyen Anh-Tu
Published: April 2023

The Mixed Aggregation by Comprehensive Normalization Technique (MACONT) is a well-known Multi-Criteria Decision-Making (MCDM) method with significant benefits compared to traditional approaches. The key difference that distinguishes this method from most others is the use of data normalization techniques and aggregation approaches. MACONT uses three different data normalization techniques simultaneously along with two aggregation approaches throughout its evaluation process. This reduces the derivation of evaluation values and enhances the reliability of the final decision results, making the process more precise and convergent. However, the original MACONT emphasizes the integration of multiple normalization techniques of the same type of criteria that might perform badly in some circumstances. This paper proposes combination strategies of six normalization techniques to be coupled with the MACONT to help the normalized data synthetically reflect the original information and solve different types of data, criteria, and alternatives. The proposed approach was applied in four case studies. In all studies, the ranking results were compared with the other MCDM methods, producing the same best alternatives and overcoming the cases when the original MACONT did not work properly.
Prediction of the Adhesion Strength of Coating in Plasma Spray Deposition
Authors: Vu Duong
Published: April 2023

The goal of this work is to validate the existing plasma spray mathematical models, using a calculation method and the comparison with experimental data, in order to determine their validity. A preliminary evaluation of the adhesion based on the velocity and temperature of the particles is useful to be calculated by using the mathematical model. Given the thermal-physical properties and chemical composition of a Fe-based amorphous X-5 powder, a modified model was suggested. For comparison, a series of experiments using plasma spraying of the X-5 powder were conducted. The significance of the current study consists of the model validation by using the data of the plasma spraying of the Fe-based amorphous material as a potential substitution for saving production costs by using ordinary air as the plasma generation gas. The findings show the discrepancy between the models and the experimental results. The prediction of adhesion using the mathematical models does not cover essential parameters such as the enthalpy of the particle stream. It is necessary to improve the mathematical models, including the modified one, based on the experiment results, with different pairs of particles and substrate materials. The proposed formula is applicable during the preliminary design of the spray process and the development of a new torch construction.

Context-Based Aspect-Oriented Requirement Engineering Model
Authors: Idate Sonali R. , Rao T. Srinivasa , Mali Dipak J.
Published: April 2023

Mobile applications are context-oriented systems that involve the use of context information while operating. Mobile applications demand tackling context information in the early phase of software engineering. A context-aware system demands a different approach to handling the influence of the context on a system's requirements. Aspect-oriented Requirement Engineering separates concerns throughout requirements, called crosscutting concerns, in the early phase of software development to improve the modularity of complex applications. Capturing requirements embedded within context is a challenging procedure. This study aimed to identify such contextual characteristics of requirements in the early phase of software engineering, using natural language processing techniques, by proposing Context-Based Aspect-Oriented Requirement Engineering (CB-AORE) to visualize the existence of crosscutting concerns. CB-AORE performs context modeling to analyze the context dependency with base requirements and helps the analyst to visualize the correlation of functional and non-functional requirements with context. A case study analyzed the identification of context and its use to identify crosscutting concerns.

Authors: Bouaita Bilal , Beghriche Abdesselem , Kout Akram , Moussaoui Abdelouahab
Published: April 2023

Association rule methods are among the most used approaches for Knowledge Discovery in Databases (KDD), as they allow discovering and extracting hidden meaningful relationships between attributes or items in large datasets in the form of rules. Algorithms to extract these rules require considerable time and large memory spaces. This paper presents an algorithm that decomposes this complex problem into subproblems and processes items by category according to their support. Very frequent items and fairly frequent items are studied together. To evaluate the performance of the proposed algorithm, it was compared with Eclat and LCMFreq on two actual transactional databases. The experimental results showed that the proposed algorithm was faster in execution time and demonstrated its efficiency in memory consumption.
A Neural Network Controller Design for the Mecanum Wheel Mobile Robot
Authors: Ly Trinh Thi Khanh , Thanh Nguyen Thi , Thien Hoang , Nguyen Thai
Published: April 2023

Advanced controllers are an excellent choice for the trajectory tracking problem of Wheeled Mobile Robots (WMRs). However, these controllers pose a challenge to the hardware structure of WMRs due to the controller's complex structure and the large number of calculations needed. In that context, designing a controller with a simple structure and a small number of computations but good real-time performance is necessary in order to improve the tracking accuracy for the WMRs without requiring high hardware architecture. In this work, a neural network controller with a simple structure for the trajectory-tracking of a Mecanum-Wheel Mobile robot (MWMR) based on a reference controller is proposed. A two-layer feedforward neural network is designed as a tracking controller for the robot. The neural network is trained with a sample input-output data set so that the error between the neural network output and the reference control signal of the supervisory controller is minimal. The neural network parameters are trained to update over time. The simulation results verified the effectiveness of the neural network controller, whose parameters are tuned adaptively to ensure a fast convergence to the desired Bézier trajectory.
Spectrophotometric Estimation of Phenylephrine Hydrochloride via Oxidative Coupling Reaction with p-Aminobenzophenone
Authors: Ahmed Hanan H.
Published: April 2023

In this research, a rapid, simple and accurate spectrophotometric approach was described for the estimation of phenylephrine hydrochloride in the pure and in its drug forms. The suggested method was based on the oxidative coupling reaction of phenylephrine hydrochloride with p-aminobenzophenone using potassium periodate as an oxidant. A taupe-red dye was formed at room temperature and showed maximum absorption at 512 nm. The linearity of the standard calibration curve was compatible with Beer's law within the concentration range of 2.0-20 μg/mL with a determination coefficient (r2=0.9986). The apparent molar absorptivity and the sensitivity of Sandell's index were calculated and found to be in the values of 0.552x104 L/mol.cm. and 0.0368 μg/cm2, respectively. The nature of the resulting dye has been studied between phenylephrine hydrochloride to p-aminobenzophenoneand and it was equal to 1:1. The limits of detection (LOD) and quantification (LOQ) were estimated and found to be 0.0094 and 0.0313 μg/mL, respectively. A relative standard deviation and a relative error were also calculated and they will be in the range of 0.0715 to 0.0216 and -0.0479% to -0.0145%, respectively. The recommended procedure was applied to assay phenylephrine hydrochloride in drops and injection and no interferences were observed from the common additives found in the drugs.

Published: April 2023

Diabetes mellitus (DM) is a metabolic disease characterized by hyperglycemia that occurs due to insulin disorders, insulin action, or a combination of both. Based on data from the 2014 IDF, Indonesia ranks 5th in the world of patients with DM. Diabetic foot is one of the chronic complications of DM that is often encountered. Early vascular assessment in the legs of a diabetic patient is recommended to reduce mortality and morbidity. The vascular examination begins with a capillary refilling examination, palpation of the lower extremity arteries, and a further ankle-brachial index assessment. The vascular approach aims to assess the vascularization of the diabetic foot is still good or has experienced occlusion or obstruction due to inadequate blood vessels. Diabetic foot care is based on the classification recommended by the International Working Group On Diabetic Foot. Management of diabetic foot involves a variety of multidisciplinary, one of them with a vascular approach. The vascular approach also aims to determine the appropriate therapy for the diabetic foot. This study aims to provide better understanding

Published: April 2023

Introduction: The vast majority of renal injuries occurred by blunt mechanisms with fall and motor vehicle crashes. Massage therapy is widely used as traditional medicine and has been viewed as a safe treatment tool without major complications or side effects. Renal rupture due to traditional massage therapy is a rare complication. Moreover, it occurs even less commonly considering the anatomical location of the kidneys, where they are well-protected. The purpose of this article is to present a case of a patient with an acute ruptured kidney due to traditional massage therapy four hours before admission to the hospital.
Case description: A 52-years-old man came to the emergency department with right upper and lower abdominal pain. The pain began in the flank region and spread to the right lower abdomen. He visited a traditional massage therapist and received massage therapy in the abdominal and back region with no history of other trauma or other activities before admission. The hemodynamic status was unstable. Physical examination revealed tenderness in the right upper and lower abdominal region and bulge area at the right flank region. We performed an emergency laparotomy due to hemodynamic instability. Right retroperitoneal exploration revealed active bleeding from a ruptured right kidney. Thus right nephrectomy was performed. Post-operative non-contrast CT scan showed ureteral obstruction due to the presence of right distal ureteral stone
Conclusion: Kidneys with anatomical abnormalities such as hydronephrosis and blunt abdominal trauma may increase pressure in the hydronephrotic renal pelvis and cause a rupture. We suggest that surgeons should be cautious of the possibility of renal rupture in blunt trauma due to the change of normal morphological structure of the kidney and attenuation of the renal parenchyma.

Authors: Bourne Cabezas Arianna Doménica , Rueda López Roberto
Published: April 2023

Introducción: Las convulsiones febriles afectan entre el 2-5% de los niños entre 6 meses y 5 años a nivel mundial. Se han identificado varios factores de riesgo, entre esos, las deficiencias nutricionales. El objetivo de este trabajo es analizar las características de los pacientes con convulsiones febriles y establecer si la desnutrición crónica infantil es un potencial factor de riesgo en la aparición de convulsiones febriles.
Materiales y Métodos: Estudio de casos y controles, observacional y analítico. Se seleccionaron las historias clínicas 186 pacientes de entre 6 meses a 5 años que fueron admitidos con diagnóstico de convulsiones febriles. Se utilizaron pruebas de estadística descriptiva e inferencial.
Resultados: Se evaluaron 125 pacientes en el grupo de casos y 61 en el grupo control. El 66% del grupo de casos eran del género masculino, mientras que el 57% del grupo control eran del génerofemenino. El aumento de peso se estableció como factor protector (p=0.049). Los lactantes menores presentan mayor riesgo (p=0.010). Así también, la talla fue un factor protector (p=0.003). Además, los pacientes con bajo peso y talla tienen mayor riesgo de convulsionar; también se encontró asociación de otras variables como anemia y el grado de aumento de temperatura.
Conclusión: Se observó la asociación entre el aumento de peso y talla como factores protectores en la aparición de convulsiones febriles en la población estudiada. De acuerdo a estos hallazgos, se considera necesario implementar políticas orientadas a combatir la desnutrición, para mitigar los posibles desenlaces relacionados a las crisis convulsivas febriles.

Mean age from observations in the lowermost stratosphere: an improved method and interhemispheric differences
Authors: Wagenhäuser Thomas , Jesswein Markus , Keber Timo , Schuck Tanja , Engel Andreas
Published: April 2023

Abstract. The age of stratospheric air is a concept commonly used to
evaluate transport timescales in atmospheric models. The mean age can be
derived from observations of a single long-lived trace gas species with a
known tropospheric trend. Commonly, deriving mean age is based on the
assumption that all air enters the stratosphere through the tropical (TR)
tropopause. However, in the lowermost stratosphere (LMS) close to the
extra-tropical (exTR) tropopause, cross-tropopause transport needs to be
taken into account. We introduce the new exTR–TR method, which considers
exTR input into the stratosphere in addition to TR input. We apply the
exTR–TR method to in situ SF6 measurements from three aircraft
campaigns (PGS, WISE and SouthTRAC) and compare results to those from the
conventional TR-only method. Using the TR-only method, negative mean age
values are derived in the LMS close to the tropopause during the WISE
campaign in Northern Hemispheric (NH) fall 2017. Using the new exTR–TR
method instead, the number and extent of negative mean age values is
reduced. With our new exTR–TR method, we are thus able to derive more
realistic values of typical transport times in the LMS from in situ SF6 measurements. Absolute differences between both methods range from 0.3 to 0.4 years among the three campaigns. Interhemispheric differences in mean age are found when comparing seasonally overlapping campaign phases from the PGS and the SouthTRAC campaigns. On average, within the lowest 65 K potential temperature above the tropopause, the NH LMS is 0.5±0.3 years older around March 2016 than the Southern Hemispheric (SH) LMS
around September 2019. The derived differences between results from the
exTR–TR method and the TR-only method, as well as interhemispheric
differences, are higher than the sensitivities of the exTR–TR method to
parameter uncertainties, which are estimated to be below 0.22 years for all
three campaigns.

Desde principios de la pandemia de SARS-CoV-2, se ha debatido el curso de la enfermedad COVID-19 en personas con VIH. Por un lado, la inmunodeficiencia derivada de la infección por VIH y mayor prevalencia de comorbilidades estarían asociadas al desarrollo de enfermedad grave. Por otro lado, la disfunción inmunológica podría evitar una respuesta inflamatoria exacerbada.
En este trabajo de revisión analizamos la evidencia disponible en cuanto a la relación entre la manifestación clínica de COVID-19 y la respuesta inmune humoral y celular contra SARS-CoV-2 en el contexto de la coinfección con VIH. La bibliografía sugiere que las personas con VIH que reciben tratamiento antirretroviral logran respuestas eficaces contra SARS-CoV-2, a pesar de presentar algunas de las funciones celulares alteradas. Esto sugiere un impacto significativo de la terapia antirretroviral, no solo en el control del VIH sino en potenciar la inmunidad para restringir otras infecciones.

Antecedentes. El recuento de unidades formadoras de colonias (UFC) de Cryptococcus en el líquido cefalorraquídeo (LCR) sería un marcador fiable para el pronóstico del paciente y una herramienta simple y económica. Objetivo. Evaluar la utilidad del recuento de UFC de Cryptococcus spp. y compararlo con las variaciones de antígeno capsular de Cryptococcus (AgCr) en LCR.

Materiales y métodos. Se realizó la revisión de historias clínicas de pacientes con meningoencefalitis por Cryptococcus asociada con el sida en nuestro centro, entre febrero de 2016 y julio de 2020. Se evaluaron los valores de UFC y AgCr en LCR durante la evolución de la micosis.

Resultados y Discusión. Se analizaron datos de 94 episodios clínicos de 85 pacientes con un total de 297 observaciones de muestras de LCR. 

Se evidenció el valor del recuento de UFC por ser un marcador de viabilidad y de carga fúngica.

El recuento de UFC bajo no necesariamente coexistió con un nivel bajo de AgCr.  

Con respecto a la evolución en el tiempo, la mayoría de los pacientes fueron diagnosticados con una alta carga fúngica y su descenso ocurrió más rápido que el del AgCr por lo que reflejaría la mejora del paciente permitiendo tomar conductas al respecto.
