Published: November 2024

The study of nanomaterial for solar energy conversion via zinc oxide (ZnO) nanostructure has grounded for decades. Many reports shown that ZnO nanorod can substitute the expensive titanium-based as the working electrodes of dye-sensitized solar cell (DSSC). The main lack of ZnO-based to the titanium-based is the low charge carrier. Fortunately, this issue can be solved by metal doping to the ZnO nanorod. The dopant can improve the physical and optical properties, such as increasing charge carrier and effective surface area. These properties can lead higher efficiency of DSSC in converting the light to electricity. In this paper, we enhance the ZnO nanorod properties through the doping of aluminum (Al). For obtaining optimum results, we varied the dopant concentration of 1, 1.5, 1, and 3.0%. The Al-doped ZnO nanorod was grown by a seed-mediated hydrothermal method at 90oC for 8 hours. The physical properties were analyzed by field emission scanning electron microscopy (FESEM) and EDX, while the photovoltaic properties were analyzed by J-V curve analysis. An improvement of photovoltaic performance up to 200 % is obtained by the ZnO nanorod with 1.0% Al-doped concentration.

Published: November 2024

A study was conducted to measure the growth rate of catfish (Pangasius sp.) due to feeding on a mixture of fermented mustard and cabbage waste flour (FMCWF). Catfish are distributed in each container per box, consisting of five fish with an initial weight of 3-5 grams. During 56 days of cultivation, three times a day were fed with a feeding rate of 5%. The randomized block design method was used as the concept of this research. There were five treatments and each treatment was repeated three times. The type of catfish feed provided consisted of factory feed and its mixture with different percentages of FMCWF: P0 (Manager Feed brand Matahari Sakti); P1 (FMCWF 15%); P2 (FMCWF 30%); P3 (FMCWF 45%); and P4 (FMCWF 60%). Observations were made on several parameters such as absolute weight growth, feed conversion ratio, and water quality. Based on the ANOVA test (analysis of variance), the results showed that the growth rate of catfish was influenced by FMCWF with a significant effect (p<0.05). The best growth rate was given to P2 treatment (FMCWF 30%) with an absolute weight growth of 8.11 g and a feed conversion ratio of 1.5.

Authors: Zamri Zamri , Aziz Muhammad Safwan , Soerbakti Yan
Published: November 2024

WiFi signal is an electromagnetic wave that in its transmission does not require an intermediary medium used in communication. However, signal intensity can be affected by the medium through which it travels, as is the case in the workplace. So the WiFi signal no longer provides the same strong intensity. Therefore, it is necessary to research how to determine the area with the most effective WiFi signal intensity due to fluctuating signal propagation in a closed workspace. This research is conducted by showing the source point of the router and receiver that will be used as a trip to the position function, then measurements will be made on the WiFi signal depending on the change in position. In addition, the influence of temperature and humidity in the room is also related. The results showed that the highest WiFi signal intensity was at a distance of 0.5 m from the router with a power loss of -47 dBm. While the value of the lowest WiFi signal intensity is in the range of 3 m with a power loss of -25 dBm.
Electrocardiogram signal patterns detection of myocardial ischemia rhythm using an artificial neural network based on MATLAB/Simulink
Authors: Arianto Yendra , Hamdi Muhammad , Meyzia Bunga
Published: November 2024

This study aims to design a computer program to detect myocardial ischemic heart defects through electrocardiogram (ECG) signal patterns and their accuracy. Myocardial ischemia is a heart disorder caused by the narrowing of the blood vessels in the walls of the heart. The method used is a backpropagation-based artificial neural network (ANN) based on MATLAB/Simulink. The input data is trained to recognize the target pattern of the ECG signal based on the potential and time in the ST segment. The optimal weight of the results of the ANN backpropagation algorithm is used in the process of testing the ECG signal pattern to obtain the ANN output. The ANN output was analyzed for potential depression or elevation to identify normal heart or myocardial ischemia. The results of the training show that from several architectures that have been tested, the optimal ANN architecture is 1 hidden layer with 11 hidden units. These results are obtained from the epoch parameter and the mean square error (MSE) value as well as the accuracy of each architecture. The backpropagation ANN learning process requires 8 epochs to achieve the performance goal with MSE 4.03 × 10-9. The system can recognize target patterns with a training accuracy of 99.82%. The test results of the ANN program identification system can detect myocardial ischemia and normal heart abnormalities with an accuracy of 86.7%. Some data were not detected because the ANN output did not meet the criteria for cardiac ischemia or normal myocardium on the ECG signal. Based on the accuracy of the ANN program identification system, the detection of myocardial ischemia rhythm ECG signal patterns using ANN can be said to work well.

Published: November 2024

The productivity of palm trees grown is generally measured in monthly and yearly periods, but on a shorter time scale, it is particularly measured by the plant maintenance of palm trees. Consideration of the general productivity in time is how to produce good fruit fertilizer (chemical aspect), healthy plants, fast growing and evolving (agricultural aspect), and genetic type of palm that grows (biological aspect). However, the growth and production on the physical aspect is still less attention. Through physical treatment, the growth of palm trees can be optimized to support aspects of the previous aspects, as it has been proven in advanced countries on the plant's Aloe Vera, Avocado, and pine trees. In this paper, the methodology proposes a direct current voltage treatment to the palm tree that can accelerate the flow of ions to grow and develop nutrients. The palm tree samples are aged 1 to 5 years corresponding to the provision of 10, 16, 25, 35, and 50 V for each of the ages of the palm tree respectively. Identifying samples before and after treatment by electricity is based on the geometry of leaves, midribs, and ions effect. There have been reduced and increased levels of nutrients. This identification can optimize the productivity of palm trees.

Published: November 2024

Water infiltration is one important factor for plant growth. Water that cannot seep into the pores of the soil creates a pool of water so that soil permeability is low. From these conditions, it is necessary to conduct research to determine the rate of water seepage in the soil. This study aims to analyze. the rate of water seepage on the ground by utilizing the difference in floating voltage. Based on the difference in floating voltage, two-dimensional modeling of the stress distribution and the distribution of water infiltrate time into the ground using the method of adding water repeatedly. The sample in this study consisted of 2 types of soil, compost and sand. Land with high permeability can increase the rate of infiltration thereby reducing the rate of water. The results of this study concluded that the pore size and particle arrangement greatly affect the rate of water seepage.

Authors: Saktioto Saktioto , Maulana Agam Muhammad , Yupapin Preecha , Hairi Haryana Mohd
Published: November 2024

Fiber Bragg grating (FBG) is an optical sensor component that has better performance than other optical and electronic components. FBG has a very high sensitivity to changes in temperature and strain, is small in size, and is resistant to electromagnetic wave interference and multiplexing. In this study, FBG is used to monitor the fluid flow rate in a pipe by analyzing changes in the output power generated by the FBG. This research was designed by varying the pipe diameter, measurement position, and fluid flow rate. The diameters of the pipes used are 5.95, 7.01, 8.79, and 10.32 mm. The fluid flow rate that passes through each pipe is also varied. The measuring position is placed at 1/3 2/3, and 3/3 pipe diameter. The fluid flow rate and the output power generated by this FBG are measured using an anemometer and optical power meter respectively. The FBG used in this study has a center wavelength of 1310 nm and 1550 nm. In this study, the value of power generated from pipe 1 of position 1 FBG with a wavelength of 1550 nm is 15.1 dBm, while at a wavelength of 1310 nm is -26.23 dBm which indicates that the power generated from FBG with a wavelength of 1310 is the biggest. The speeds obtained at pipe position 1 from the anemometer measurements are 0.79, 1, 1.82, and 2.22 m/s which are directly proportional to the power generated at the 1550 wavelength FBG, -15.1, -15.12, -15.47, and -15.43 dBm, respectively. So it can be concluded that the greater the speed generated by the fluid flow, the greater the power generated.

Background: Numerous clinical studies have demonstrated that the therapeutic efficacy of combining nifedipine and enalapril in treating hypertension with coronary heart disease surpasses that of nifedipine as a stand-alone treatment. However, the current evidence is not yet sufficient due to limitations in the sample size, and further validation is needed. To analyze and assess the clinical impact of nifedipine combined with enalapril on hypertension complicated with coronary heart disease, and provide evidence for rational drug use in clinic. Methods: We employed a revised version of the Jadad scale to assess the quality of the research literature following a rigorous screening process. The statistical analysis was performed utilizing the software RevMan 5.4.1 for data analysis. Heterogeneity in the studies was evaluated based on the results of the Q test (P value), and the OR value of the combined effect was calculated using either the model with fixed effects or the one with random effects, with the results presented in a forest plot. Furthermore, a sensitivity analysis was conducted by excluding articles with the highest impact, and potential bias in publication was assessed through the utilization of a funnel plot. Results: A total of 183 articles were initially identified, and after a comprehensive review, 14 clinical randomized controlled trials were chosen for analysis. The meta-analysis findings revealed that the trial group displayed a significantly higher overall effectiveness rate compared to the control group (OR=3.47, 95%CI 2.40-5.03). Additionally, the trial group exhibited a more pronounced reduction in blood pressure and greater enhancement in cardiac function (OR=5.55, 95%CI). Conversely, the control group had a lower occurrence of ischemic events compared to the trial group (OR=0.35, 95%CI 0.24-0.50). Sensitivity analysis confirmed the stability and reliability of the combined effect size results (OR=3.91, 95%CI 2.51-6.09, P<0.00001). However, based on an assessment using funnel plot results suggested potential bias in publication. Conclusions: The combined administration of nifedipine and enalapril exhibits enhanced effectiveness compared to the sole use of nifedipine in individuals diagnosed with hypertension and coronary heart disease, rendering it a valuable alternative for clinical application.

This paper presents a meticulous analysis of the UNCTAD's 2019 data pertaining to commercial ships, with a particular focus on Chinese-funded vessels. The objective is to assess their status and further predict the demand for shipping talents within the Hainan Free Trade Port. Notably, it is revealed that approximately 34.91% of the Chinese-funded ocean-going ships operate under flags of convenience, representing a substantial share of 55.9% in terms of tonnage. In order to address this situation and enhance the attractiveness of Hainan for vessel registration, a comprehensive "master plan" has been devised. Recent statistics indicate a favorable trend towards a reversal in this trend, with more Chinese-funded ships choosing to register in Hainan. Consequently, there is a pronounced demand for skilled shipping talents within the free trade port.Furthermore, this article delves into the intricate nuances of nautical technology vocational education, both domestically and internationally. It underscores the crucial role of skilled professionals who possess a global perspective and offers suggestions for fostering international collaboration and enhancing educational resources. Additionally, it identifies and discusses the challenges encountered in the Hainan Free Trade Port, along with proposed measures for improvement. The article emphasizes the imperative for responsive reforms to ensure that educational competencies are aligned with global standards. The implementation of these measures is anticipated to bring about transformative changes in nautical technology education within the Hainan Free Trade Port, thereby contributing significantly to the overall progress of the maritime industry globally.

Published: November 2024

En los sistemas de procesamiento de materiales que involucran fenómenos como reacciones químicas ó transferencia de masa en las interfases gas-líquido ó gas-sólido-líquido, las características de las dispersiones son determinantes en el rendimiento de dichos procesos. Se instalaron cuatro inyectores de gas tipo tobera con orificio de descarga de abertura variable en una celda de flotación subaireada y una columna de flotación piloto para la producción de dispersiones de burbujas de gas en medios líquidos. Se obtuvieron datos experimentales de las características de las dispersiones de gas (diámetro de burbuja, fracción de gas y área superficial de flujo de burbujas) generadas con estos inyectores. Los diámetros promedio de burbujas fueron medidos mediante la técnica fotografía-análisis de imágenes utilizando un sensor para obtener muestras de nubes de burbujas. La fracción volumétrica de gas se estimó utilizando un sensor basado en la conductividad eléctrica de las fases. Del tratamiento estadístico de los datos se derivó un modelo matemático que relaciona el diámetro promedio de burbuja con la caída de presión en el dispersor que ocasiona el flujo superficial de gas a través del mismo, el flujo superficial de líquido en el equipo de dispersión, las características dimensionales del inyector y la tensión superficial del medio. La validación del modelo que predice diámetros promedio de burbuja se realizó en una columna de flotación de 50 cm de diámetro y cuatro metros de altura con los cuatro inyectores instalados. Los resultados experimentales muestran que es posible diseñar ó predecir diámetros promedios de burbuja empleando este tipo de dispersores de gas tipo jet con descarga de abertura variable en medios acuosos.

Nuevo recubrimiento protector para cilindros de GNC reforzados con fibra de vidrio
Authors: Elaskar Omar , García Jorge
Published: November 2024

En el presente informe se concluye con la descripción de una Patente de Invención [1] referente a un recubrimiento protector para cilindros de Gas Natural Comprimido (GNC) como aplicación inmediata, ya que es una innovación con posibilidades de transferir a la industria, como así también para otras aplicaciones tales como cilindros de presión de gases, cilindros de buceo, recipientes de cohetes, reservorios de presión aeronáuticos, etc. Este trabajo fue el resultado de una serie de estudios, ensayos e investigaciones llevadas a cabo en el marco de un proyecto subsidiado por el Ministerio de C. y T. de la Provincia de Córdoba. La invención consta de un recubrimiento elástico resistente a ácidos, con capacidad de deslizarse por encima de la superficie delPlástico Reforzado con Fibra de Vidrio (PRFV) de un cilindro de presión y protegerlo de la corrosión bajo tensión que se produce en la fibra de vidrio ante el contacto con agentes ácidos. El mecanismo de funcionamiento es el siguiente, cuando un recipiente con PRFV es presurizado, se puede observar un agrietamiento interfibras en la resina, que deja expuestas a las fibras a los agentes ácidos que puedan encontrarse en el ambiente. Bajo esta situación el cilindro se encuentra en condiciones de alto riesgo de rotura y explosión. Para ello, se propone un recubrimiento superficial por sobre el material compuesto, que protege a las fibras de vidrio de la corrosión ácida bajo tensión y las aisla del ambiente. El trabajo se inició con el análisis del comportamiento mecánico de un cilindro con PRFV, luego se continuó con el análisis de su recubrimiento protector en sus diversas alternativas, y finalmente se realizó la propuesta de un recubrimiento protector flotante, demostrando analíticamente una mejora en el comportamiento con esta última solución. Por ello, y a partir de las últimas simulaciones numéricas realizadas en base a la nueva solución adoptada para dichos recubrimientos protectores, se propuso la solución tecnológica de recubrimiento flotante, que fuera patentada ante el INPI. El recubrimiento propuestos se caracteriza por la posibilidad que tiene de deslizarse o “flotar” por sobre el PRFV que protege, y de esa manera deformarse en un área mayor sin alcanzar altas deformaciones concentradas, que puedan ocasionar roturas o “pinchaduras” después de varios ciclos.

Optimização da geometria de próteses arteriais: caso estacionário
Authors: Santos Ferreira de Castro Catarina Rosa , Conceição António Carlos Alberto , Costa Sousa Luísa
Published: November 2024

Próteses artificiais são utilizadas na cirurgia de bypass para restabelecer o fluxo sanguíneo em artérias ocluídas ou severamente estenosadas. A configuração do bypass, incluindo a geometria da prótese e da anastomose, tem uma forte influência na dinâmica do fluxo sanguíneo, verificando-se por vezes a ocorrência de fenómenos de recirculação e criação de zonas de estagnação, positivamente relacionadas com a reestenose póscirúrgica. A optimização, utilizando técnicas de simulação numérica, pode e deve ser utilizada para encontrar soluções que garantam uma minimização dos riscos pós-cirúrgicos. A procura de geometrias de próteses optimizadas tem sido apresentada na literatura quase sempre restringida apenas a uma única função objectivo. Investigação recente para desenvolver uma nova metodologia para optimização multi-objectivo de próteses é aqui apresentada. Ao contrário das metodologias de optimização de uma única função objectivo, a solução deste problema não é um único ponto, mas sim uma família dos pontos permitindo uma selecção de acordo com a experiência do investigador em cirugia vascular. O esquema deste trabalho de optimização multi-objectivo considera um algoritmo genético que procura geometrias sinusoidais óptimas de próteses artificiais iterando sobre resultados de um programa de elementos finitos desenvolvido para a simulação do fluxo sanguíneo. Relativamente à escolha de funções objectivo considera-se a optimização da eficiência do fluxo, minimizando a variação de pressão e ainda a minimização de zonas de ocorrência de recirculação e de estagnação. Os resultados numéricos evidenciam os benefícios da optimização da geometria da prótese antes da cirurgia do bypass arterial, minimizando zonas da recirculação e de estagnação do fluxo e diminuindo a probabilidade de restenose arterial pós-cirúrgica. Este trabalho representa o uso formal de algoritmos de optimização multiobjectivo no projecto de cirurgia hospitalar.
Tratamiento variacional de placas laminadas con rótulas intermedias utilizando la teoría de primer orden
Authors: Quintana María Virginia , Grossi Ricardo O.
Published: November 2024

El problema de vibraciones libres de placas con presencia de rótulas elásticamente restringidas y situadas en puntos intermedios, es de interés en ciertas aplicaciones de la ingeniería. Una línea intermedia con rótulas en una placa, puede ser usada para facilitar la apertura de puertas, la plegadura de portones y para simular ciertas fracturas. La presencia de las rótulas genera condiciones cuyas expresiones analíticas son análogas a las de las condiciones de contorno y complican notablemente la resolución, tanto analítica como numérica, de los problemas correspondientes. Es importante notar que no existen estudios en la literatura, del problema de vibraciones libres de placas gruesas elásticamente restringidas en sus contornos y que además posean rótulas intermedias restringidas elásticamente. El objetivo de este trabajo es la obtención, mediante las técnicas del cálculo de variaciones, de los problemas de contorno que describen el comportamiento estático y dinámico de placas con una línea intermedia con rótulas. En el estudio se consideran placas laminadas moderadamente gruesas modeladas mediante el uso de la teoría de primer orden, la cual permite tener en cuenta los efectos de la inercia rotatoria y de las deformaciones transversales por corte. El uso de la teoría mencionada permite obtener mayor precisión en la determinación de los coeficientes de frecuencia y los modos superiores de vibración, con respecto a los proporcionados por la teoría clásica de placas.
