Published: July 2024

Introduction. When manufacturing printed circuit boards (PCBs), including their prototypes, the proper alignment of PCB layers is mandatory. While the causes and preventive measures against misalignment in PCBs manufactured using conventional technologies are known, research into alignment errors in 3D-printed PCBs is still ongoing. Another task regarding 3D printing, which is related to topological accuracy (alignment errors in particular), consists in ensuring the opportunity to remove the printed part of the product in order to perform operations thereon, such as embedding components, followed by its return and continuation of the printing process.Aim. Numerical estimation and analysis of the causes of layer-to-layer alignment errors in PCBs manufactured using 3D printing.Materials and methods. The research was conducted using the following materials and equipment: Polyethyleentereftalaatglycol (PETG); an Ultimaker Cura slicer; an Ender 3 S13D printer; a brass nozzle with a diameter of 0.3 mm. The study was conducted using the facilities of the Additive Technologies Center, Bauman Moscow State Technical University. Interlayer alignment errors are estimated by microsection analysis and X-ray inspection, as well as using the misalignment decomposition method described by Yu.B. Tsvetkov for electronics.Results. The possibility of manufacturing PCB prototypes with three conductive layers is demonstrated, including a method for removing the printed part of the product and its further return in the printing process using printed pins. Large-scale distortions were found to make the largest contribution to the alignment error: on average, approximately 150 gm for each layer when compared to its 3D model and approximately 60 gm when comparing the topology of the top layer with the bottom layer. These values exceed the common misalignment value of 50 gm for the pin lamination process. This substantiates the need to control and minimize temperature effects, e.g., using 3D printers with a thermostatically-controlled chamber.Conclusion. The conducted analysis of possible causes of misalignment emergence determines the significance of temperature gradients that occur during 3D printing. The proposed manufacturing method allows the printed part of the product to be removed and further returned into the printing process, which can be used to produce PCB prototypes with three conductive layers.

This study aims to analyze the effectiveness of sediment control structures, such as sabo and consolidation dams, and river normalization on sediment control in the Omu River after the earthquake in Sigi Regency on September 28, 2018. The analysis was conducted using the Universal Soil Loss Equation (USLE) method based on average rainfall data over 20 years. Erosion and sedimentation volumes before and after the earthquake were analyzed to understand the changes. The results showed that in 2020, the erosion volume reached 120,700.27 m³/year, and sedimentation was 17,030.81 m³/year, an increase from 2017, which recorded an erosion volume of 91,282.60 m³/year and sedimentation of 12,879.97 m³/year. Sediment transport simulation with daily discharge over 12 years indicated that in Scenario-1, sediment could be reduced by 10.81%, and in Scenario-3 by 23.18%. Meanwhile, simulation with Q100 flood discharge in Scenario-2 showed sediment reduction by 47.18%, and in Scenario-4 by 62.96%. The general conclusion of this study is that sediment control structures and river normalization are effective in reducing sediment volumes. Specifically, the construction of sediment control structures has proven to significantly reduce erosion and sedimentation. This research highlights the importance of structural improvements in mitigating post-disaster erosion impacts. The results of this study can serve as a reference for planning and implementing sediment control in disaster-prone areas.

Objetivos: La presente investigación analiza los factores determinantes del desarrollo tecnológico en las industrias manufacturera y de servicios que reciben financiamiento estatal en Colombia. El objetivo es identificar los elementos críticos que afectan la innovación y el desarrollo tecnológico en estas industrias para proponer mejoras en las políticas públicas. Métodos: Se adoptó un enfoque mixto, combinando análisis cualitativos de casos y técnicas de regresión Poisson, utilizando datos de la Encuesta de Desarrollo e Innovación Tecnológica (EDIT IX), que incluyó 7,762 empresas manufactureras y 9,304 empresas de servicios y comercio. Resultados: Los resultados indican que los factores clave que influyen en la innovación y el desarrollo tecnológico son la insuficiencia de recursos financieros propios, la falta de información sobre mecanismos de apoyo y las dificultades en el acceso al financiamiento estatal. La escasez de recursos financieros propios limita la capacidad de las empresas para invertir en actividades de investigación y desarrollo. Además, la falta de información sobre los mecanismos de apoyo disponibles impide que muchas empresas accedan a recursos que podrían impulsar su desarrollo tecnológico. Por último, las dificultades en el acceso al financiamiento estatal, debido a procesos burocráticos y falta de claridad en los requisitos, representan una barrera significativa para muchas empresas. Conclusión: Estos hallazgos destacan la necesidad de reformas en las políticas públicas para fortalecer el ecosistema de innovación y desarrollo tecnológico en Colombia. Las reformas sugeridas incluyen la simplificación de los procesos para acceder al financiamiento estatal, la mejora de la divulgación de información sobre los mecanismos de apoyo disponibles y el aumento de la disponibilidad de recursos financieros propios para las empresas. Estas medidas contribuirían a mejorar la competitividad y productividad de las empresas, fomentando un entorno más favorable para la innovación y el desarrollo tecnológico. La investigación subraya la importancia de ajustar las políticas públicas para crear un entorno más propicio para la innovación y el desarrollo tecnológico en Colombia, mejorando así la competitividad y productividad empresarial.
BACTERIOLOGICAL ASSESSMENT OF SOME COMMERCIALLY SOLD YOGHURT IN UTURU, ABIA STATE, NIGERIA: A PRELIMINARY STUDY
Authors: Ekeleme U. G. , Mohammed A. 
Published: July 2024

A preliminary study was carried out to determine the bacteriological quality of commercial yogurt sold in Uturu, Abia State, Nigeria. This involved isolation, characterization and antibiotics susceptibility of bacteria isolated from some commercially sold yoghurt in Uturu. Five different brands of yoghurt coded A to E were microbiologically analyzed using standard microbiological methods. The total viable count ranged from 0.9×102 cfu/ml – 2.0x103 cfu/ml, coliform count ranged from 0.4×102 cfu/ml – 1.0×103 cfu/ml, total staphylococcal count ranged from 1.1×101 to 1.8×102. Bacterial isolated include Staphylococcus species, Streptococcus species, Bacillus species and Lactobacillus species. The antibiotics susceptibility pattern of the bacterial isolates proved that drovid had the highest zones of inhibition from 31.8±1.2 mm to 36.1±0.3 mm, followed by oflaxacin (29.5±0.1 mm to 35.0±0.8 mm). The presence of coliform and Staphylococcus in the yoghurt may be as a result of unclean water used in the production, contaminated milk and unhygienic condition of the handlers. It is recommended that yoghurt producers, sellers and handlers should ensure a high level of hygiene and avoid long exposure of yoghurt before selling to consumers.
