Respiratory disorders are a critical health problem. Respiration is a vital activity for the proper functioning of the body. Pandemic SARS-CoV-2 virus is a highly contagious disease and causes rapid spread of droplets. This study aims to determine the effectiveness of the bioradar sensor used in non-contact respiration monitoring by exploring the distance to find out the optimal distance for sensor readings in monitoring respiration rate per minute. The results of this study for the 3 treatments given to respondents did not affect the results of measuring respiration rate. At distances of 10 cm and 25 cm they produce 40-43 times/minute, distances of 50 cm and 75 cm produce 33-36 times/minute, distances of 100 cm produce 20-22 times/minute and distances of 125 cm and 150 cm are not detected. The highest error value is -100.00% at a distance of 125cm and 150cm and the lowest error value is 3.39% at a distance of 100 cm. based on the results of the analysis of the effectiveness of sensor readings on distance, which is quite effective at a distance of ±100 cm. It is hoped that this research can reduce the level of disease transmission during the Covid-19 pandemic. The results of the study showed that the three treatments given to respondents did not affect the results of respiratory rate measurements. At a distance of 10 cm and 25 cm, it produced 40-43 times/minute, at a distance of 50 cm and 75 cm it produced 33-36 times/minute, at a distance of 100 cm it produced 20-22 times/minute, and at a distance of 125 cm and 150 cm it was not detected. The highest error value is -100.00% at a distance of 125 cm and 150 cm, and the lowest error value is 3.39% at a distance of 100 cm. Based on the analysis of the effectiveness of the sensor reading at a distance, it was found to be quite effective at a distance of ±100 cm. The implication of this study is that this bioradar sensor is effective in monitoring breathing rate at a distance of about 100 cm. The results of this study are expected to reduce the level of disease transmission during the Cov-19 pandemic, as non-contact monitoring can help in avoiding droplet spread, which is one of the ways the virus is transmitted. This study provides important information on the use of bioradar sensors in non-contact monitoring of breathing that can be used to improve the safety and quality of healthcare, especially in the context of a pandemic

The development of technology in the health sector as well as modern science and technology, both in the treatment of patients and in technology that facilitates the development of health science itself, has experienced very rapid development. Various operational processes in hospitals have now undergone many developments, namely by replacing human performance with automated systems. One of them is an automatic system for monitoring heart rate and human body temperature. Heart rate and body temperature are two important parameters used by medical personnel to determine a person's physical health and mental condition. Because if the heart rate and body temperature are not normal, more effort is needed to prevent unwanted things from happening. Heart disease is known as one of the highest causes of death in the world, while body temperature can detect something that is in the body. In order for monitoring tools to be more practical and efficient to use, tools have been made with real time monitoring and can be monitored remotely. The design of this tool uses the Max30102 as a BPM sensor which has a digital output, also the Mlx90614 sensor as a temperature sensor which has a digital output, then processes it on and displays the value on the I2C LCD and sends data to the Thingspeak platform assisted by ESP32 as a wifi module. BPM has the smallest error of 0.23% and the largest of 2.11% while Temperature has the smallest error of 0.59% and the largest of 3.37%. The results of this study can be implemented on patient monitors to increase the efficiency of the remote monitoring system

The intensive growth in the capacity of combine harvester bunkers observed in recent years is accompanied by an increase in their metal consumption and, accordingly, an increase in the pressure on the soil of the running systems of this equipment. established Significant excesses of the maximum pressure of combine wheels relative to the standard level were established by our previous studies. But, the lack of methods for comparative assessment of the impact of combine propulsion on the soil does not allow us to correctly select the most effective option for the soil conditions of specific agricultural enterprises. This publication proposes a method for comparative evaluation of combine harvesters of different classes, both in terms of pressure on the soil, which changes during the process of filling the bunker with grain, and in terms of the relative area of the field subject to compaction with different vertical loads. It was revealed that when filling the bunkers with grain, the increase in the maximum pressure on the soil of the driving wheels of the Don 1500B, Akros 550, KZS 3219 and Torum 780 combines will be 17, 43, 31 and 68 kPa, respectively, or 8.4, 19.4, 15.3 and 29.1%. With the permissible maximum pressure on the soil in the summer equal to 210 kPa, the areas of tracks of the specified combine harvesters with excess pressure will be 14.0, 24.0, 15.0 and 18.4% of the field area, respectively. In addition, the article provides a visual representation of the results of a comparative assessment of harvesting machines, including the intervals of maximum pressure of combine propellers at the beginning and at the end of filling the bunker with grain.

It is known that at the present stage of development of the agro-industrial complex, the ozonation process is increasingly being used. This is an environmentally friendly method of processing agricultural raw materials in order to disinfect, deodorize, disinsect, increase the growth qualities of seeds, etc. It is worth noting that, despite such an active use of ozone, the question remains not fully understood how the gas spreads in the grain during its processing. The article presents the results of research to determine the shape and size of the source of the ozone-air mixture divergence in the grain heap. It has been experimentally established that the ozone in the grain diverges in a shape close to an ellipsoid. The size of the lesion depends on the saturation time and, as a result, the received dose of ozone treatment. As the duration of the experiment increases, the radius of the ellipsoid increases more than its height. Based on the results of experimental studies in the Matlab program, a model of the behavior of ozone in grain is constructed depending on its processing modes. Using regressions based on Gauss processes, the shape and size of the distribution center of the ozone-air mixture in the grain were predicted with a change in the ozonation time. The selection of model parameters is based on Bayesian optimization in the Regression Learner application from the Statistics and Machine Learning Toolbox of the Matlab application software package. The electronic program allows you to optimize hyperparameters and obtain confidence intervals for predicted values. The research results make it possible to predict the behavior of ozone in grain, which is necessary to determine the number of gas supply nozzles inside a granary of any volume.

Despite the popularization of ozone technologies in agriculture, the theoretical aspects of the interaction of an ozone-air mixture with grain material remain under study. The simplified assumption that the change in the amount of ozone absorbed by the grain is proportional to the initial gas concentration does not accurately describe this process. Attempts to analytically determine a certain constant of the rate of ozone absorption by a unit of grain volume were also unsuccessful. The resulting expression was transcendental at that time. Its solution was possible only when performing repetitive calculations, that is, using the iteration method on a personal computer. The use of the modern Matlab application software package made it possible to establish a constant rate of ozone absorption per unit grain volume. However, the experiments have shown that during the experiment this constant changes significantly, including depending on the conditions, therefore this theoretical approach requires clarification. The laws known in physics describing the diffusion process have been adapted to the ozone treatment process. The application of the Langmuir-Schaefer equation for the number of ozone molecules adsorbed on the grain surface and Fick's second law made it possible to determine the rate of ozone diffusion and the change in ozone concentration over time, taking into account the characteristics of the grain pile. A dependence was obtained for the ozone diffusion coefficient, which characterizes the ability of grains to absorb ozone through cell membranes, and the ozone decomposition constants. Under normal storage conditions, these temperature-dependent values can be considered constant. The analytically obtained dependences will allow us to determine the ozone diffusion coefficient and the ozone decomposition constant experimentally.

Chatter Identification in Milling of Titanium Alloy Using Machine Learning Approaches with Non-Linear Features of Cutting Force and Vibration Signatures
Authors: S Nair Viswajith , K Rameshkumar , S Saravanamurugan
Published: March 2024

The generation of chatter during machining operations is extremely detrimental to the cutting tool life and the surface quality of the workpiece. The present study aims to identify chatter conditions during the end milling of Ti6Al4V alloy. Experimental modal analysis is carried out, and stability lobe diagrams (SLDs) are developed to identify machining parameters under stable and chatter conditions. Experiments are conducted to acquire cutting force and vibration signatures corresponding to machining conditions selected from the SLD. Non-linear chatter features, such as Approximate Entropy, Holder Exponent, and Lyapunov Exponent extracted from the sensor signatures, are used to build Machine Learning (ML) models to identify chatter using Decision Trees (DTs), Support Vector Machines (SVMs) and DT-based Ensembles. A feature-level fusion approach is adopted to improve the classification performance of the ML models. The DT-based Adaboost model trained using dominant non-linear features classifies chatter with an accuracy of 96.8%. The non-linear features extracted from the sensor signatures offer a direct indication of the chatter and are found to be effective in identifying the machining chatter with good accuracy.

Good financial management is essential for the financial well-being of a family. Financial management is heavily reliant on the financial literacy of the family. Financial literacy will assist families in understanding risk, making good investment decisions, and developing disciplined money management practises. The Raoda village community does not yet have a solid grasp on financial literacy. The majority of people are still unable to plan investments and manage financial risks. This project aims to educate and enhance financial literacy in the Raoda Village community on Family Financial Management. The activities began with observation and cooperation with the village government, followed by the production of activity plans, materials, and aid in the preparation of plans and assessments. Following completion of this programme, it was discovered that the family was capable of making their own plans and managing simple family finances. There were some participants in this activity who, due to their education level and age, were unable to properly organise their family finances. Aside from these variables, the bulk of women's labour as housewives is the most important determining factor. Several factors contribute to the lack of financial literacy in setting plans and planning for strong financial governance.

O vírus HPV está diretamente ligado ao desenvolvimento de câncer genital, verrugas genitais e lesões de pele. Sabendo que a infecção por HPV é um fator crucial para o câncer do colo do útero, a vacinação contra o HPV tem um papel fundamental na redução da incidência de doenças cervicais e lesões pré-cancerígenas. Objetivos do estudo: Analisar a cobertura vacinal contra o HPV e sua relação com lesões precursoras no colo do útero, bem como outros indicadores da doença. Metodologia: Realizou-se um estudo descritivo retrospectivo na região sul do Brasil, no período entre 2014 e 2019, com foco na população feminina que era alvo da campanha de vacinação, excluindo as meninas de 9 anos. Foram avaliadas as faixas etárias de 10 a 19 anos e a população em geral. Os dados foram coletados através do Sistema de Informação em Saúde do DATASUS. Resultados encontrados: Em 2014, houve um maior percentual de meninas vacinadas com a primeira e segunda dose, com 56,5% e 35,8%, respectivamente. A partir de 2016, houve uma redução na cobertura vacinal, especialmente em relação à primeira dose. Mesmo com a vacinação iniciada em 2014, houve um aumento de 134% nos casos de Neoplasia Intraepitelial Cervical (NIC) na região até 2019. A faixa etária de 14 a 19 anos foi a mais afetada, com predominância de casos de NIC 1. O número de casos de câncer de colo do útero aumentou, tanto de carcinoma (+63,6%) quanto de adenocarcinoma. Discussão dos resultados: A região sul do Brasil não atingiu a meta de 80% de cobertura vacinal estabelecida pelo Ministério da Saúde. Considerações finais: Fica evidente a necessidade de reavaliar os programas de vacinação existentes, visando o controle de doenças associadas ao HPV que poderiam ser prevenidas através da imunização.

The article substantiates the possibility and value of involving an entrepreneur in the work of certain enterprises outside the narrow framework of the firms they founded as managers with extensive entrepreneurial experience, thereby helping such enterprises to succeed in competition. It is proposed to take into account the size of the enterprise, because a unified approach to appointment of a manager is not suitable for all economic entities. The purpose of the article is to determine the value of attracting entrepreneurs to the board of directors who have created other firms, and their ability to increase the value and efficiency of companies that they have not created. Some enterprises in certain industries are more suitable for management by external entrepreneurs, while in other firms the effectiveness of their involvement will be low. This thesis should form the basis of corporate decisions concerning appointment of external entrepreneurs to their board of directors. Studies have shown that enterprises headed by owners perform better than those run by external professional managers. Based on the resource point of view when analyzing the firm, it was shown that entrepreneurs who have created other firms that act as external directors are more focused on increasing investments in research and development and higher sales growth rates. Their impact on the value of enterprises is greater among firms in industries with intensive use of research and development work and in competitive industries. Such business directors from the outside increase the value of the company due to their risk inclination and ability to anticipate demand patterns and create new markets.

Authors: Theofilou Paraskevi , Vlastos Dimitris D.
Published: March 2024

The COVID-19 pandemic has had significant impacts on the overall quality of life experienced by patients suffering from various types of cancer. This systematic review aimed to explore the level of health-related quality of life among cancer patients during the COVID-19 pandemic. A systematic review was performed on articles written in English and indexed in the PubMed database, retrieved using the keywords “COVID-19,” “quality of life,” and “cancer” combined with the logical operator AND. Our investigation revealed a significant disruption in the quality of life of cancer patients due to COVID-19, with a pronounced impact on their psychological well-being stemming from the protective measures implemented to curb viral transmission. Given that cancer patients already belong to one of the most vulnerable groups, they are particularly susceptible to negative consequences. Moreover, delays in diagnosis and treatment occurred due to restrictive measures, exacerbating disease progression. The findings from this systematic review underscored the significant impact of the pandemic on cancer patients, who exhibited a markedly diminished quality of life. In conclusion, it is vital that all health systems respond effectively to crises, eliminating any form of discrimination among patients and ensuring the uninterrupted provision of oncology care without any postponements or delays.

Para exemplificar como tais medidas devem ser adotadas, foi escolhida Abramites hypselonotus (Ordem Characiformes, Família Anostomidae) como organismo modelo, uma espécie de piau também conhecida comumente como zebrinha, abramites ou piau-pedra. Assim, o protocolo aqui apresentado aborda orientações sobre o período de quarentena, as especificações das dimensões do recinto de exposição, o controle da qualidade da água (como temperatura, pH, oxigênio dissolvido e série nitrogenada), sanidade e biossegurança, alimentação, comportamento e enriquecimento ambiental. Vale ressaltar que não buscamos sanar as orientações sobre boas práticas com peixes em aquários públicos, mas sim incentivar e divulgar informações que podem ser adotadas de acordo com cada espécie ou grupo de peixes. Portanto, acreditamos que a adoção de boas práticas com peixes de água doce e comportamento de maneira mais natural em aquários públicos sejam uma importante oportunidade para a educação ambiental e conscientização da população sobre a conservação ambiental, além de proporcionar melhor qualidade de vida aos animais.
Numerical Simulation of the Effect of Fusion Welding Processes on Residual Stress in Stainless Steel Pipe Weld Joints Used in Fast Reactors
Authors: Ragavendran M , Vasudevan M
Published: March 2024

The main structural material used in the building of Fast Breeder Reactors (FBR) is stainless steel of type 316L(N). Finite Element Model (FEM)-based simulations were carried out to understand the effect of various welding processes on the residual stresses induced in 316L(N) stainless steel primary sodium-carrying pipes with an inner diameter of 208 mm and a wall thickness of 5.6 mm. The welding processes considered include multi-pass Tungsten Inert Gas (TIG) welding, A-TIG, laser, hybrid laser-TIG, and Hybrid laser-Metal Inert Gas (MIG). First, single or hybrid heat sources are chosen based on the welding process, and then weld bead profiles obtained during simulation are made to match with that of the actual weld bead profiles obtained during experiments. Then, the optimised heat source is employed for the thermal analysis. The thermal analysis output is then successively linked and provided as input to the mechanical analysis, which uses an isotropic hardening model to predict hoop and axial residual stresses in pipe weld joints. The results show that the A-TIG weld joint exhibited lower hoop stress (165 MPa at inner diameter and -2 MPa at outer diameter) in comparison with that of the other weld joints. The lower residual stress is attributed due to the straight-sided weld bead, lower peak temperature, and slower cooling rate of the A-TIG welding. Therefore, A-TIG welding is recommended among the chosen fusion welding processes for welding of 316L(N) stainless steel primary sodium carrying pipes to minimise the residual stresses and mitigate the premature failure of the pipe weld joints.

The main objective of the present study is the investigation of the behaviour of starch powder incorporated at different levels (0, 5, 10, 15, 20, 25, and 30 wt%) on the compressive strength and microstructural properties of metakaolin-based geopolymers. Sodium silicate with a molar ratio of SiO2/Na2O of 1.6 was used as the hardener and standard metakaolin was used as the aluminosilicate source. The results showed that when metakaolin was replaced by starch from 0 to 15 wt%, the compressive strength increased from 36.50 to 64.12 MPa. When metakaolin was replaced by starch above 15 wt%, the compressive strength decreased from 64.12 to 29.43 MPa. That of the reference geopolymer material is 36.50 MPa.The infrared spectra of the geopolymer composites indicate that the Si-O-C bonds are formed. The thermal behaviour of geopolymer composites containing starch shows a mass loss at around 100 and 278 °C. The geopolymer material without starch only shows a loss of mass at around 100 °C. The micrographs of the geopolymer composite with 15% by weight of starch show that the matrix is more compact, more homogeneous, and denser than the one without starch. On the contrary, possibly due to a large amount of unreacted starch in its network, the micrographs of the geopolymer composite obtained after the incorporation of 30 wt% starch show a heterogeneous microstructure. It can be concluded that suitable starch content for the synthesis of geopolymer composites would be around 15% by weight.
External Debt and Poverty Headcount Ratio in West African Countries: Does Governance Matter?

Published: March 2024

This paper analyses the link between external debt and poverty headcount ratio in the fifteen (15) West African countries, taking into account governance. Using the feasible generalized least squares (GLS) panel method for the period 1996-2021, we find that an increase in external debt contributes to the worsening poverty headcount ratio in the region. Then, enhancing governance while borrowing external funds does improve the poverty level. The regression shows that in West African Countries, governance indicators as well as the composite index of governance and the interaction term (governance composite index* external debt) contribute significantly to the reduction of the poverty rate. Therefore, there is a need for West African governments to be cautious when borrowing external funds and work towards sustainable debt management to prevent negative effects on poverty rates. In addition, the level of good governance should be improved in external debt management and poverty ratio reduction.
