Gullo Marín, Maira Alejandra | 2022

The Human Rights of people has always been a controversial issue, but this time we went there, we treated the issue from a population that has historically been vulnerable and has been forgotten by society and on many occasions by the State itself, due to the lack of guarantees that it grants to the inhabitants of the street. Once the problem of the rights of the inhabitants of the street has been addressed, we ask ourselves the following question: What is the scope of the guarantees of the fundamental right to health of the inhabitants of the street of Barranquilla?. The present degree work develops a socio-legal methodology with a qualitative approach, describing the human rights of people with a deep emphasis on the population of street dwellers in the city of Barranquilla between the years 2019-2021. Data collection was carried out through exhaustive research bibliography in sufficient documentary sources with sufficient veracity and first-hand information, which were subjected to a study and in-depth analysis to be able to extract the relevant information and data. Finally, results are issued with diagnoses made from a social and legal perspective, because this issue has a direct impact on the evolution we have as a society and seeks continuous improvement, safeguarding the right to a dignified life that Colombia promulgates as a Social State of Law

Peralta Redondo, Juleidys José | 2022

The COVID-19 pandemic has caused not only physical but also psychological and emotional consequences in those who have been directly or indirectly impacted by the virus. The teaching population was one of the groups in which most change was generated as a result of the pandemic; moving to a new way of working from home, not being able to place limits between work schedules and work spaces and at the same time, having to comply with household chores. The objective of this research is to identify the psychological effects caused by the COVID-19 pandemic on teachers in the department of Atlántico. In order to obtain the data, a population sample of 78 teachers was used, the information was collected by means of a form composed of sociodemographic questions, questions aimed at knowing the levels of motivation and questions to know the modifications they had in their work due to the pandemic, Beck's Hopelessness Inventory and SCL-90. Results: it was found that anxiety, depression and stress, manifested in somatization, are more evident in women than in men, likewise, it is observed how the motivation of teachers has been affected as a result of the pandemic, showing that it has decreased compared to before the pandemic, and it is also identified which factors influence the decrease in motivation.

...
Hernández Fernández, Joaquín | 2022-09-01

The study of the presence of bisphenol analogs in the environment has been very relevant in recent years because their toxic potential has been discovered, and since they are not regulated like bisphenol A, their use and presence in industry has been excessive. This study identifies and quantifies for the first time the presence of bisphenol A and four uncommon bisphenol analogs in waste from polypropylene (PP) and polyethylene terephthalate (PET) production processes that may originate from the degradation of some compounds used during resin synthesis in Colombia to determine the effectiveness of removal of these components. The data obtained show that the treatments used in these waters are insufficient to eliminate 40% of the bisphenols present in them, and when evaluating the profiles of compounds, it is clear that the compound with the highest removal during the PP process was D-BPA-1, while the compound with the highest removal during the PET process was D-BPA-4, indicating that identification and elimination systems for bisphenols are rudimentary.

Impact of traces of hydrogen sulfide on the efficiency of ziegler–natta catalyst on the final properties of polypropylene
...
Hernández Fernández, Joaquín | 2022-09-19

Sulfur compounds are removed from propylene through purification processes. However, these processes are not 100% effective, so low concentrations of compounds such as H2S may be present in polymer-grade propylene. This article studies the effects of H2S content on polypropylene polymerization through the controlled dosage of this compound with concentrations between 0.07 and 5 ppm and its monitoring during the process to determine possible reaction mechanisms and evaluate variations in properties of the material by TGA, FTIR, MFI, and XDR analysis. It was found that the fluidity index increases directly proportional to the concentration of H2S. In addition, the thermo-oxidative degradation is explained by means of the proposed reaction mechanisms of the active center of the Ziegler–Natta catalyst with the H2S molecule and the formation of substances with functional groups such as alcohol, ketones, aldehydes, CO, and CO2 by the oxidation of radical complexes. This study shows for the first time a reaction mechanism between the active center formed for polymerization and H2S, in addition to showing how trace impurities in the raw materials can affect the process, highlighting the importance of optimizing the processes of removal and purification of polymer-grade materials.

Quantification and removal of volatile sulfur compounds (VSCS) in atmospheric emissions in large (Petro) chemical complexes in different countries of America and Europe
...
Hernández Fernández, Joaquín | 2022-09-11

The present research was focused on the determination and removal of sulfur-containing compounds in industrial emissions of liquefied petroleum gas purification processes in petrochemical plants located in the USA, Brazil, Colombia, Spain, and Italy. For the analysis of volatile sulfur compounds (VSCs), an improved analytical methodology was implemented. The performance of the method was evaluated for eight VSCs in a linear dynamic range between 0.1 and 50 ppm. The concentrations of the eight VSCs in the deethanizer affluents ranged from 11 to 49 ppm for all the studied plants, which exceed the limits specified by institutions and administrations in occupational health and safety. The concentrations of the eight VSCs in the splitter affluents were lower than 4 ppm for all the considered plants. The emissions from each column depended upon its operating rate, with the highest concentrations estimated at 45 TM kg−1 and the lowest ones at 25 TM kg−1. A zeolite-packed prototype column was fitted at the outlet of the splitter and deethanizer columns to reduce the environmental effect of the examined VSCs. This technique was verified and put into practice on an industrial scale, obtaining VSC removal percentages of between 85 and 91%.

Resignificación de la práctica educativa en el contexto de un modelo pedagógico orientado al desarrollo de competencias en ciencias naturales
...
Vera Morales, Yurani | 2022

The main objective of this research project was to set up a methodological route that, based on the pedagogical model, enables the resignification of educational practice for the development of skills in the natural sciences. The methodology used was oriented from the rationalist epistemological approach, with a research paradigm based on critical rationalism, of a qualitative-quantitative nature. In the same way, a research design is established, through a phase of a theoretical, empirical and propositional nature. The study sample consisted of 23 teachers from the Román Rural Educational Center and the Monterrey Agricultural Educational Institution. It should be noted that the sample used is of the Census type, due to the low number of teachers in the chosen population. To collect the information, a questionnaire was applied to teachers, and a statistical and analytical procedure was carried out on the results obtained by 11th grade students in the Icfes tests in recent years. On the other hand, a process of documentary analysis was carried out, in accordance with the institutional documents selected for this purpose. In this way and in accordance with the research purpose, after the analysis of the data, a methodological route of resignification of the educational practice was generated, with which it is discrepancy to establish that the educational institutions that can ensure the congruence between the didactic sequence and the practice education, without thinking of a pedagogical model assumed in an Institutional Educational Project, will achieve a better academic performance, contrary to an institution that, from the independence of the teacher, designs and assumes the educational practice.

Social responsibility and spiritual intelligence: university students’ attitudes during COVID-19
...
Severino-González, Pedro | 2022-09-21

Human behavior during COVID-19 has led to the study of attitude and preferences among the population in different circumstances. In this sense, studying human behavior can contribute to creating policies for integral education, which should consider the convergence between social responsibility and spiritual intelligence. This can lead to the sensitization of practices and attitude modification within society. The purpose of our research was to explore the spiritual intelligence attitudes of university students from the perspective of social responsibility, considering the sociodemographic characteristics of the research subjects during the COVID-19 pandemic. Our research design is quantitative and sectional, due to the use of two quantitative scales. The participants were university students from a city located in south-central Chile. A total of 415 participations were collected, of which 362 applications were valid. Statistically significant differences were found according to gender and age. Women and the student cohort between 18 and 24 years of age placed more importance on spiritual necessities. We thus highlight the necessity to have adequate spaces for spiritual intelligence training given its links with socially responsible behavior and, finally, the development of explanatory studies to determine its causalities. In practice, these results contribute to designing an educational policy on the formation of integral spiritual intelligence for future professionals.

...
Betancur-Ramos, Alejandro | 2022

The Colombian government approved Law 1964 of 2019, which is expected to favor the massification of electric vehicle technologies. Since 2010, this technological migration has begun, which has not managed to have a substantial impact on the automotive sector. The research reviewed the industry's regulatory framework and identified variables that impact the market. Through the MICMAC methodology, they are evaluated to establish the key variables that can influence the other variables. The results obtained identify that the price of electricity and the lack of knowledge or business models are critical elements in improving the development of the electric vehicle sector. These results indicate that it is necessary to propose methodological changes to decrease the price of electricity and promote the development of business models so that users take an active role in the market.

Developed teamwork optimizer for model parameter estimation of the proton exchange membrane fuel cell
...
Syah, Rahmad | 2022

This paper proposes a new optimal methodology for model parameters estimation of the Proton Exchange Membrane Fuel Cell. The main purpose here is to design a newly developed metaheuristic technique to deliver a model with higher accuracy. In this study, we utilized two modifications for the Teamwork Optimizer to get higher accuracy. The two modifiers are opposition-based learning and chaotic mechanism. The results show that using the opposition-based learning, the population diversity has been kept, owing to the greater population size due to the solution space, and using the Chaos theory, the population diversity has been increased. This is proved by applying the Improved Teamwork Optimizer to minimize the Root Mean Square Error and Integral Absolute Error between the suggested model and empirical data. The validation has been done by applying the proposed Improved Teamwork Optimizer to two studied cases, which are Nexa Proton Exchange Membrane Fuel Cell and NedSstack PS6 Proton Exchange Membrane Fuel Cell, and comparing it with other published works. Simulation results showed that the proposed method with 1.14 Integral Absolute Error and 0.21 Root Mean Square Error for NedSstack PS6 Proton Exchange Membrane Fuel Cells and with 12 Integral Absolute Error and 0.17 Root Mean Square Error for Nexa Proton Exchange Membrane Fuel Cells provides the minimum error value among the other optimization techniques. This shows the higher potential of the proposed method for use as the parameter estimator for Proton Exchange Membrane Fuel Cells.

Application of wavelet characteristics and gmdh neural networks for precise estimation of oil product types and volume fractions
...
Mayet, Abdulilah | 2022-09-30

Given that one of the most critical operations in the oil and gas industry is to instantly determine the volume and type of product passing through the pipelines, in this research, a detection system for monitoring oil pipelines is proposed. The proposed system works in such a way that the radiation from the dual-energy source which symmetrically emits radiation, was received by the NaI detector after passing through the shield window and test pipeline. In the test pipe, four petroleum products—ethylene glycol, crude oil, gasoil, and gasoline—were simulated in pairs in different volume fractions. A total of 118 simulations were performed, and their signals were categorized. Then, feature extraction operations were started to reduce the volume of data, increase accuracy, increase the learning speed of the neural network, and better interpret the data. Wavelet features were extracted from the recorded signal and used as GMDH neural network input. The signals of each test were divided into details and approximation sections and characteristics with the names STD of A3, D3, D2 and were extracted. This described structure is modelled in the Monte Carlo N Particle code (MCNP). In fact, precise estimation of oil product types and volume fractions were done using a combination of symmetrical source and asymmetrical neural network. Four GMDH neural networks were trained to estimate the volumetric ratio of each product, and the maximum RMSE was 0.63. In addition to this high accuracy, the low implementation and computational cost compared to previous detection methods are among the advantages of present investigation, which increases its application in the oil industry.

Geospatial analysis of Ae. aegypti foci in southern Brazil
...
Goellner, Emanuelle | 2021

Arboviruses have become a major public health problem in recent decades. Ae. aegypti has been the vector responsible for the greatest spread of these diseases. This study aims to identify outbreaks of Ae. aegypti, through the capture of egg traps installed in the City of Passo Fundo, in southern Brazil, to understand the geospatial dimensions aimed at mapping to control the proliferation of these mosquitoes. Methodologically, 20 points were selected for trap placement using an Irregular Triangular Network. Then, ovitrap traps were distributed at the sampled points, during all seasons in 2016 and 2017. From the collected eggs, a colony of wild Ae. aegypti mosquitos was established and stored for future testing. Using geotechnologies, the mapping of each trap was carried out with an accuracy of up to 50 cm. The greatest number of outbreaks occurred in the autumn and summer seasons, with an average temperature of 18 °C and 350 mm of rain, and 22 °C and 300 mm of rain, respectively. Spring and winter, when temperatures are lower, 16 °C and 17 °C, respectively, saw fewer outbreaks. The places that stood out in the study were the two most densely populated and least vegetated areas of the city, Bairro Vila Luiza and the Centro neighborhood. This demonstrates that vegetation suppression and high urban density rates contribute to the proliferation of Ae. aegypti on a global scale.

The validation of the instruments was carried out through expert judgment, and to establish reliability, the Cronbach's coefficient Alpha was established. Based on the results obtained, a pedagogical proposal was suggested for the comprehensive training of students from the conception and functionality of the coexistence manual. The results indicated that the institutions are not applying the guidelines set forth in the coexistence manual, thus discovering deficiencies in the various actions, strategies and methods for the promotion of school coexistence.
