Published: October 2024

Abstract Climate change significantly impacts farmers' decision-making regarding the supplementary irrigation of coffee cultivated in areas experiencing water deficits. The aim of this study was to analyze the production cost and profitability of Arabica coffee under different irrigation and rainfed regimes in the Brazilian Cerrado. Four scenarios were evaluated: I. scenario before significant climate events and the pandemic, II. scenario with the effects of pandemic and climate events, III. scenario with average national productivity and average productivity in irrigated areas, and IV. scenario of specialty coffees. In Scenario I, only the rainfed treatment did not demonstrate economic viability because it did not yield a positive net present value (NPV). Scenario II showed higher internal rate of return (IRR) than Scenario I. The national production and Cerrado scenarios proved viable under the evaluated price conditions and interest rates. The rainfed sector was highly attractive for the specialty grain scenario (IV) than for other scenarios. Productivity and the amount paid per bag of coffee were identified as the variables that had the most significant impact on the IRR of the coffee crop. Therefore, economic and technical analyses should be conducted before investing in coffee farming to ensure the success of each production system.

Published: October 2024

Abstract Trophic relationships shape ecosystem structure by regulating energy flow and nutrient cycling, impacting prey consumption and prompting behavioral adaptations in prey species to mitigate risks. While much is known about fish antipredator behavior in marine environments, less is understood about these dynamics in freshwater environments. We investigated the antipredator behavior of an Amazonian floodplain fish, Crenuchus spilurus, across different habitat structural complexities. Through experiments, we examined how the number of individuals (1 and 4 individuals) and habitat structural complexity (low, medium, high, and very high) influence the fish response to predator presence. Small groups showed longer flight initiation distance (FID) than solitary individuals, suggesting a possible collective defense strategy against approaching predators. The structural complexity of the habitat did not have a direct effect on FID. Additionally, we noted variations in refuge usage by the fish across different habitat structural complexities. These findings underscore the interplay between behavioral and environmental factors in prey adaptation to predation risk in aquatic ecosystems.

Published: October 2024

Resumo Esta pesquisa aborda a localização e a territorialização do Objetivo do Desenvolvimento Sustentável (ODS) voltado para a promoção da igualdade de gênero. O objetivo principal deste estudo foi propor uma leitura municipalizada parcial da Agenda Global 2030 e avaliar o desempenho do município de Humaitá-AM quanto à duas metas do ODS 5. A metodologia utilizada consistiu na adaptação da proposta de indicadores do Instituto de Pesquisa Econômica e Aplicada (Ipea), baseados nos indicadores já produzidos pelos consensos internacionais, considerando-se os diversos acordos globais e os compromissos nacionais de enfrentamento das questões de gênero e a implementação de medidas que visem mudanças. Foi possível analisar a eficácia das políticas públicas mediante a análise de séries históricas com as médias estaduais e municipais no período de 2015 a 2021. Os indicadores avaliados apresentaram dados concretos e mensuráveis sobre a evolução das conquistas das mulheres no campo político, econômico e social, observando-se uma maior participação da mulher na sociedade humaitaense. Ainda que estejam surtindo efeitos positivos, os processos de mudança estão evoluindo de forma lenta, requerendo uma melhora substancial na eficácia das políticas existentes voltadas para as mulheres no município. Constatou-se que, ainda há muito a se fazer, pois, barreiras culturais machistas e paradigmas precisam ser quebrados e enfrentados, a fim de se alcançar uma maior participação feminina e assim cumprir os compromissos da Agenda 2030, para a construção de uma democracia plena e equitativa, em direção ao desenvolvimento sustentável.

This study investigated the minichromosome maintenance 6 (MCM6) rs4988235 polymorphism in professional football players, comparing genotype and allele frequencies with a sedentary control group. The control group comprised 64 participants with no history of athletic activity, while the athlete group included 20 football players. DNA extraction from blood samples was performed using a PureLink DNA isolation kit, following the manufacturer's instructions. Real-Time PCR was employed to analyze the MCM6 rs4988235 polymorphism in the isolated DNA. Statistical analysis of the acquired data was conducted using chi-square analysis via IBM SPSS 21.0 software (IBM Statistical Package for Social Sciences Corp., Armonk, NY, USA). A p-value less than 0.05 was considered statistically significant. The CC genotype was absent in all football players. Conversely, CT (10%) and TT (90%) genotypes were identified in 2 and 18 individuals, respectively. In the control group, the distribution of genotypes was as follows: CC (0%), CT (17, 26.6%), and TT (47, 73.4%). The C allele frequency was 5% (2 individuals) in football players and 13.28% (17 individuals) in the control group. The T allele frequency was 95% (38 individuals) in football players and 86.72% (111 individuals) in the control group. No statistically significant differences were observed between the football players and the control group regarding genotype (p = 0.122) or allele frequencies (p = 0.149).

Published: October 2024

The article examines a wide range of problems of Soviet scientific and educational construction in the middle of the 20th century in order to identify the main prerequisites for the separation of a new university TIRiET from the Tomsk Polytechnic Institute. The corpus of sources used for this purpose is represented mainly by materials from periodicals and memoirs of contemporaries. The main attention is focused on the ways and forms of development of higher education in Siberia. The connection between current technological challenges and the priorities of science and higher education in the east of the country is emphasized. The specifics of Tomsk as the leading scientific and educational center of the country are analyzed. Based on the structural-functional approach, its organizational core is identified. As part of this, the focus is on the ideological and personnel potential of local radiophysics and radio engineering. The boundaries of Tomsk radio engineering by the early 1960s are outlined. A special emphasis is placed on the consideration and analysis of the scientific and educational environment of the Tomsk Polytechnic Institute (TPI), which became the basis for the identification of TIRiET. The influence exerted by radiophysicists of Tomsk University on radio engineers of TPI illustrated by the most striking personal examples of teachers and scientists is revealed. This allows us to conclude that the key feature of Tomsk radio engineering is the initial presence of a deep fundamental component. Based on this, other conclusions regarding the direction and nature of the further institutional development of radio engineering education in Tomsk are drawn. Ways to overcome personnel problems and material and technical shortages, the adoption of an organizational and structural format of the educational process and scientific research were determined by the wide-profile specialization of the first students of the Department of Radio Engineering and the Faculty of Radio Engineering. This trait directly manifested itself at the turn of the 1950s and 60s, when young teams of radio engineers at the Polytechnic Institute began implementing large-scale projects of national importance. The considered range of issues allows us to make a theoretically significant conclusion that the decisive factors for the opening of the first specialized radioelectronic university in Siberia were the hybrid nature of the Tomsk radio engineering school, which contained certain elements of fundamental university science as well as high administration abilities demonstrated by the radio engineers themselves.
Participation of Komsomol in elections of village councils in Siberia 1929
Authors:   Novosibirsk State University, Kromer Lev V.
Published: October 2024

The article considers participation of the Komsomol in election of village councils on the territory of Siberian Krai in 1929. In his study, the author has tried to reveal, which tasks were assigned to the Komsomol by the top Party leadership, how the Communist League of Youth interacted with population during elections and which results this interaction had. As the source base of study, the following were used: reporting materials from State Archive of Novisibirsk Oblast (GANO) and State Archive of Altai Krai (GAAK), party and Komsomol press, statistical books and collections of documents. The election campaign of 1928–1929 took place on the background of escalated social-political and economic situation: food supply difficulties in some regions and using of extraordinary methods to peasants, who did not want to supply bread to the state. Party-state leadership explained bread deficit as a result of malicious actions of capitalist elements, therefore in the new election campaign a course to increase the class struggle was declared. The major press organ of the Communist party – a newspaper “Pravda” (“The truth”) has announced one of the tasks for the elections as “"to expel from the councils of the individuals, who are Kulak’s (village bourgeoisie) agents”. The results of the elections had a special significance in the eyes of the leaders of the USSR, so they expected Komsomol to exert its forces to organize and conduct this campaign. The Central Committee of All-Union Leninist Young Communist League (VLKSM) has forbidden local organizations conducting the other campaigns at the same time. Along with city workers, thousands of Komsomol officials were sent to the country to convince public opinion to support the Soviet authorities. Theatrical methods of agitation were actively used. In addition, the Komsomol members had responsibility for preparing elections and organizing pre-election meetings of youth, where their coevals could nominate candidates from among themselves and shape elector’s mandate. De facto, during the elections, Komsomol acted alone, without the leadership of the Communist Party. Party functionaries often harmed directly the work of Komsomol cells, taking away Komsomol functionaries for own purposes. Nevertheless, according to the results of elections, Komsomol increased its representation in village councils, due to active work with public opinion and imposing candidates to population. The increase in the number of Komsomol members was actually the main goal of Sibkraikom (Siberian Regional Committee) VLKSM - they did not hope that the elected people would be able to continue their careers as members of the council and assumed that soon they would give up their seats to the new Komsomol members, who have not yet shown themselves to be bad in the eyes of voters.

El surgimiento del Instituto Jorge Robledo se dio en un contexto en el que se conjugaron elementos clave para que su propuesta de renovación pedagógica no tuviera el mismo desenlace de otras iniciativas previas de educación privada y laica. Las ideas y propuestas pedagógicas de sus fundadores se presentaron como una alternativa prometedora para las familias influyentes de Medellín. Sin embargo, una cosa eran los procesos de formación en el aula y otra muy distinta la administración de un plantel educativo. Ante ese escenario se acogió el instituto como un proyecto de ciudad (e incluso de país) al que, de manera voluntaria, decenas de familias y empresas respaldaron con recursos económicos y su experiencia en el manejo de organizaciones. Esta obra se encarga de profundizar en los aspectos de la administración académica y financiera que resultarían claves para la permanencia del instituto en el tiempo, al igual que en aquellos propios de la vida cotidiana del instituto y de su apuesta por el fomento de diferentes actividades deportivas y culturales, lo que se ha reflejado en la heterogeneidad de sus egresados.
Reading Engagement and the Reader in the Foreign Language Classroom: Students' Perceptions on Assessment Methods
Authors: Galán-Rodríguez Noelia María
Published: October 2024

Despite the fact that Foreign Language (FL) literature is considered to be an important element in English as a Foreign Language (EFL) lessons, it is not part of the majority of classrooms (Bloemert et al. 2016). In most Spanish high-schools, FL literature is introduced by means of mandatory readers: these are often not worked on in the lessons and students are asked to read them on their own and take an exam. Taking into account that assessment methods have a direct influence on students’ level of engagement, reading motivation and learning achievement (Guthrie & Wigfield, 2000; Gujbels & Dochy, 2006; van der Watering et al. 2008), this study analyses the perceptions of 52 students in their first year of upper-secondary education on two different assessment methods during two different terms. In the first term, the reader was used in the classroom and students were asked to do an individual assignment at the end. In the second term, students read the reader on their own and took an exam. The data were gathered by means of a students’ questionnaire and systematic classroom observation. Overall, results show a preference towards the individual assignment in terms of reading engagement and a ‘deep learning’ approach to the reading experience.
Protocol for the ‘Validated Entheses-based Reconstruction of Activity 2.0’ (VERA 2.0) Method: Semi-Automated Measurement of 3D Entheseal Changes v2
Authors: Alexandros Karakostis Fotios
Published: October 2024

This protocol introduces the "Validated Entheses-based Reconstruction of Activity 2.0" (VERA 2.0), an advanced iteration of the original VERA 1.0, previously developed by the author of this protocol (Karakostis, 2022; Karakostis & Harvati, 2021; Karakostis & Lorenzo, 2016). VERA 1.0 has become a valuable tool in anthropological studies for repeatably delineating, measuring, and analyzing 3D muscle attachment sites (surface areas), demonstrating that entheseal 3D surface variation can reflect habitual muscle coordination and physical activity. VERA 2.0 builds on this foundation with significant enhancements, offering a semi-automated protocol that greatly simplifies the 3D area quantification process. It requires only one initial set of manual steps – selecting a pre-specified broader region of the bone around the enthesis – after which the remaining procedure can be fully automated using a stored filter script (e.g., mlx file in the software Meshlab). After some practice, this semi-automation can potentially reduce the entire 3D area measurement time to less than 2 minutes per enthesis (see example video below), enabling the analysis of very large skeletal samples within a few working days. Unlike VERA 1.0, which measures the entire 3D surface area of bony structures associated with a muscle and/or ligament (e.g., the entire tubercle), VERA 2.0 identifies 3D surface deformations and irregularities within the footprint of the attaching soft tissue (i.e., “entheseal changes”), which can arguably be more clearly associated with direct muscle or ligament loading. Preliminary experimental analyses, which will be presented in the validation paper associated with this protocol, indicate that VERA 2.0 can effectively and repeatably identify activity-related differences, similar to VERA 1.0. This protocol provides a comprehensive, step-by-step guide for executing the VERA 2.0 workflow, covering both manual and automated components. It is designed to enable users to achieve measurement repeatability without necessarily requiring training from the developer, though direct contact with the author is encouraged for questions or explicit recommendations regarding particular entheses.
MULTIPLE LINEAR REGRESSION OF FACTORS INFLUENCING FEMALE ENGINEERING STUDENTS’ SATISFACTION: AN APPLICATION IN SAUDI ARABIA

Published: October 2024

Students are the most significant stakeholders in any educational institution as they play a pivotal role in education. Since they are directly impacted by the quality of education in the institution, they can provide valuable insights for improving teaching methods, curriculum design, and institutional policies. Their growth and success will contribute to the development of the overall society. This research aims to model the relationship between teaching quality, assessments and facilities, practical sessions, and engineering student satisfaction using multiple regression analyses. The data was collected based on a survey prepared by the College of Engineering - girls’ campus at Saudi University. The sample analyzed in this study consisted of 5577 cases. The results show that teaching quality, practical sessions, assessments, and facilities significantly influence engineering student satisfaction (P-value < 0.05). The coefficient of determination is 0.66 indicating that the independent variables could explain 66%. The remaining 34% required further investigations.
Reflection of the Ideas of Medieval Icelanders About Fate on an Example of Gísla Saga Súrssonar
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Kukhta Victoriia
Published: October 2024

The article focuses on studying the concept of fate through the prism of Gísla saga Súrssonar. The concept of fate was an integral part of medieval Icelanders’ perception of the world. Fate, according to their ideas, is a fundamental driving force that determines the life of every person, and is always a stable and unchanging constant. It cannot be bypassed or deceived, and even knowing one’s fate, a person cannot influence it in any way. It was assumed that this is a certain fate that each individual approaches during his life path, with which he can only come to terms. Fate must be faced with courage and dignity, but it is useless to run away from it or try to change it – even mythological stories testify to this. Gísla saga, in this context, most fully reveals the conceptual meaning of fate and its influence on everyday life and decisions. It depicts the problem of the inevitability of fate which determines the life path of an individual. It is accompanied by manifestations of the inevitability of fate in the cyclical nature of events, which one by one form a closed circle of inevitability of how and why everything had to turn out exactly the way it did. Reflecting a special perception of fate, Gísla saga, thus, becomes the source that allows a visual analysis of the worldview peculiarity of the Icelanders, which they preserved even after conversion to a new faith. The plot of Gísla saga is built around a conceptual idea that has either received little attention or has been completely overlooked by researchers. The determination of fate formed the basis of the text and conditioned its structure, and our goal is to highlight as clearly as possible how and in what way this determination manifested itself and to what consequences it led. Based on the text of the saga and the experience of previous research, we analyze the plot as a complete picture, all elements of which are inextricably linked with each other. Thus, we offer a new perspective on the content of the saga and its reinterpretation.

The thermal conductivity of rocks represents one of the significant variables when investigating geothermal potential of an area on a local scale as well as regionally when performing basin analysis with the aim of estimating hydrocarbon potential. While steady-state methods of measuring thermal conductivity are presumed to yield more reliable results, transient methods allow for in situ measurements, thereby considerably simplifying and reducing measurement costs. This study was performed with the goal to expand the understanding of thermal conductivity of rocks typical for the North Croatian Basin (NCB) infill, as well as the underlying basement rocks. The measured values reveal distinct ranges across various lithologies. The thermal conductivity values measured in crystalline rocks are quite consistent, showing narrow ranges of values for each lithotype: for granite the measured values are between 2.317 and 2.486 W m-1 K-1, the value range for gneiss is between 3.332 and 3.565 W m-1 K-1 and the thermal conductivity of amphibolite is in the range between 1.549 and 1.623 W m-1 K-1. In contrast, the thermal conductivity values of sedimentary rocks vary within broader ranges – the values in sandstones range between 1.778 and 2.433 W m-1 K-1, for marlstones the registered range is between 0.917 and 2.323 W m-1 K-1, the values measured in shales range between 0.894 and 2.304 W m-1 K-1 and biocalcarenites show values of thermal conductivity between 0.990 and 2.023 W m-1 K-1. The greater variability in values measured for sedimentary rocks is attributed to the variability in porosity and fluid saturation, as well as the greater variability of mineral composition. Further research is needed to determine which factor has the greatest influence on the variability of thermal conductivity values, i.e. to establish to which extent each of the factors contributes to the measured values.

The most extensive use of coal in Indonesia is for electricity generation. Due to increasing concerns about climate change and the need to reduce emissions caused by burning coal, biomass-based fuels are becoming more competitive. The biomass carbonization process, or torrefaction, to produce solid fuel has been introduced elsewhere. This research uses sub-bituminous coal and rice husks, considering Indonesia’s large potential for both. The primary objective of this research was to determine the optimal temperature and residence time for the rice husk torrefaction process, intending to reduce the alkali oxide content that led to ash deposition. This was necessary due to the limited information available, particularly for local rice husks from Indonesia. We carried out the rice husk torrefaction at 300, 350, and 400°C temperatures for 30, 60, and 90 minutes. The results show that a temperature of 350°C and a residence time of 60 minutes were the optimal conditions. In these conditions, the potassium and sodium oxides decreased, and the calorific value increased. To get a coal-rice husk blending with a calorific value greater than 5,000 cal/g (ADB), the proportion of coal to rice husk should be 90 and 10%, respectively. The rice husk torrefaction process did not have much influence on the occurrence of ash deposition. However, the torrefaction process increased the calorific value, reduced transportation costs due to the lower moisture content, and improved grindability so that it was easy to blend with coal.

Published: October 2024

Compressed air is one of the most common methods of energy transfer in industrial and mining systems. Compressed air has numerous applications in underground mines to ensure safety (ventilation fans), carry out extraction operations (compressed air equipment and machines), and manage technical services like dewatering and the operating of spare equipment. Therefore, it is necessary to investigate the compressed air supply systems in mines to assess the sufficiency of compressed air, reduce energy consumption, and lower operating costs. Considering the significance of utilizing compressed air in underground mines, it is essential to verify the adequacy of the flow rate and permissible pressure of compressed air for all mine air consumers. This requires proper design and adjustment of the compressed air distribution network. In this paper, the compressed air network in the main compressor house of the Qaleh-Zari copper mine in Iran was investigated. To achieve this goal, the compressed air consumption in various mining operation conditions was investigated and discussed after surveying the airflow transmission lines. The pressure drops in each line were estimated as well. Regarding the results, the airflow consumption in regular mining operations is about 36 cubic meters per second. The drop in air pressure within the network lines is below the permissible limit, but the overall pressure drop is significant. In this approach, practical adjustments such as changing the diameter of the pipes, increasing the airflow pressure, and utilizing local compressors near consumers’ locations were proposed and investigated.

The Integrated Laboratory Building of Political and Social Science Faculty, located in a seismic-prone area, has been the subject of a comprehensive study of its performance using seismic response analysis. This research has yielded significant findings, gathering crucial secondary data, such as soil layers, bedrock depth, building structure, and earthquake wave information. The seismic response analysis, conducted by referencing the synthetic earthquake wave from the Bengkulu–Mentawai earthquake in 2007, with a magnitude of Mw 8.6, has provided a comprehensive overview of the earthquake waves at the foundation soil layers. The data, analysed using the finite element method to understand the structural response, revealed that the Peak Ground Acceleration (PGA) and amplification factor at the surface soil layer are 0.220g and 1.429, respectively. The most critical PGA and amplification factors at the foundation soil layer are 0.147g and 0.955. Structural analysis has revealed internal forces and beam elements experiencing over-strength, necessitating retrofitting the affected structural elements to reduce the impact. One practical and highly effective method of retrofitting involves increasing the beam dimensions by 53.12%. With retrofitting, the impact of structural deformation can be minimised, enhancing the building’s resilience in case of an earthquake of equal or greater magnitude. These findings underscore the importance of our research and highlight the significant role of engineers, architects, and researchers in ensuring the safety and longevity of structures in seismic-prone areas.
COMPUTATIONAL SIMULATION OF SEDIMENT MOTION STABILITY PROCESS ON BRIDGE ABUTMENT DUE TO CRIB PLACEMENT (CASE STUDY: HARAPAN RIVER, JAYAPURA REGENCY)

Erosion occurs when the flow of velocity in a channel exceeds the threshold velocity that causes the bed material to move. This phenomenon is observed in the Harapan River, resulting in significant impacts, such as riverbed lowering and narrowing due to the presence of water structures (bridge abutments) spanning across the river. The objective of this study is to investigate the sediment motion stability around bridge abutments before and after the installation of cribs in order to prevent structural failures. Sediment sampling was conducted at six points around the bridge abutments, using the Pebble Count method along zigzag paths. The grain size of the bed material was classified according to the Sturgess classification standard, and the material dispersion process was analysed using the Hjustorm curve. Design rainfall was transformed into design flood discharge, which was then simulated using the Two-Dimensional Hydrodynamic, comparing the river conditions before and after crib installation. In abutments without cribs, erosion occurred in direct contact with the abutment on the right side for each sediment grain diameter. However, in abutments with cribs, erosion still occurred, but it did not directly contact either abutment despite the presence of a crib. The crib prevented and protected the abutments from being eroded by the riverbed.

Published: October 2024

Natural gas has shown an increase in demand in recent years, largely due to its competitive advantages over other fossil fuels. However, in Brazil, its production and supply chain remain under the monopoly of Petrobras, which makes it difficult for new agents to enter the market and often causes other producers to dispose of their production without any financial return. Therefore, the objective of this work is to identify alternative technologies for natural gas processing, to allow other natural gas producing companies to commercialize their natural gas production without depending on Petrobras' infrastructure. As a result, three technologies were identified that are already being applied in other countries, which are: compressed natural gas, liquefied natural gas and gas-to-liquids.

Published: October 2024

This comprehensive review delves into the burgeoning role of gold nanoparticles in both cancer treatment and diagnostics. The advent of gold nanoparticle (AuNP) vaccines has opened avenues for therapeutic and prophylactic applications, suggesting the potential to prevent or treat infections and various pathologies. The exceptional efficacy of AuNPs in cancer treatment is a focal point of exploration, with ongoing investigations into their utility for targeted delivery and therapy across diverse cancer types. A distinctive attribute of AuNPs lies in their ability to selectively target cancerous cells while safeguarding healthy cells, attributed to their unique size and shape that facilitate selective accumulation in cancer cells. Upon cellular entry and aggregation, they exhibit prompt activation to eradicate cancer cells. Furthermore, AuNPs possess inherent capabilities to enhance and modulate immune responses, functioning as both an adjuvant and a delivery system. Another advantageous feature is their amenability to functionalization with diverse molecules, including antibodies and drugs, augmenting specificity and effectiveness. This customization enables precise targeting of cancer cells and direct delivery of therapeutic agents to tumor sites, mitigating the adverse effects associated with conventional chemotherapy. Despite ongoing research, the promise of AuNPs as a potent tool in the battle against cancer is evident, underscoring their potential significance in future therapeutic strategies.

Authors: Miranda Mayker , Gonçalves Gabrielly
Published: October 2024

“Let he who has had neither doubts nor difficulties in Chemistry in his school life cast the first pipette.” This science is full of information but it is often limited to formulas, memorization of concepts, experiments in laboratories and activities that only focus on its contents. The world must be seen through the eyes of science which must be used as a tool that helps to explain phenomena of nature so that all knowledge learned in school may be used for benefiting human beings. Therefore, this study aimed at making Chemistry accessible and attractive by using contextualized dialogues about “favorite beverages and their Chemistry”. This study was developed by a High School senior who goes to the Instituto Federal do Triângulo Mineiro - Campus Uberlândia Centro, Uberlândia, Minas Gerais (MG), Brazil. Contextualizing Chemistry was a tool that made teaching easier since students participated and mentioned their favorite beverages, such as soft drinks, coffee, alcoholic drinks and energy drinks. Teachers had the opportunity to teach several chemical concepts, such as methods of separating mixtures, fermentation and molecules, besides chemical structures of sugar, caffeine, ethanol and taurine. Teachers and students also talked about solubility of gas in liquid and dissolution of carbon dioxide in manufacturing of carbonated drinks. This project showed that contextualized Chemistry teaching makes students construct their own learning process.

The China Digital Seismograph Network, one of the largest national seismic networks, has been operating for over four decades which provides valuable seismic data for various scientific studies. Our investigation gathered a comprehensive dataset comprising 5,456,816 three-component waveforms from 3187 seismic events that took place over nine years (2014–2022). We assessed sensor orientations at 1056 broadband stations using the P-wave polarization method. Together with our calculation results, operation and maintenance log of regional networks, on-site checking, and manual inspection, we identified and addressed issues related to temporal changes of orientation, polarity reversal, and channel mislabeling. We found that ∼65.8% of seismometers (694) were well aligned with the absolute misorientation angle ≤3°, 20.8% of seismometers (220) were fairly well aligned with the absolute misorientation angle lying between 3° and 10°, 3.6% (38) of seismometers were misaligned exceeding 10°, and 9.8% of seismometers (104) showed a temporal variation in alignment. The fairly high consistency between our numerical results and gyrocompass measurements confirms the reliability of our investigation. We further compared the results of P-wave receiver functions analysis before and after sensor orientation correction. The findings indicate that sensor misorientation angles may lead to inaccurate and unstable seismological results. Therefore, conducting a systematic assessment, diagnosis, and correction for sensor orientation would be beneficial for advancing seismological analysis by promoting consistency, efficiency, accuracy, collaboration, reproducibility, and adaptability in data processing and interpretation.

Published: October 2024

En Cali y en el campus de la Universidad Icesi conviven cientos de especies de aves. En este libro ilustrado por estudiantes de la Universidad Icesi, se incluyeron 74 de estas especies. Algunas de ellas aprovechan los recursos urbanos como los edificios y postes para anidar, o los comederos para aves de los jardines y terrazas; incluso las lámparas de la ciudad para cazar insectos en la noche. Otras se encuentran únicamente en las zonas verdes, humedales y jardines de la ciudad, y otras son visitantes ocasionales bien sea porque son migratorias, o porque prefieren las zonas periféricas de la ciudad donde hay mayor cobertura boscosa. Además de las ilustraciones hechas a mano por más de 60 estudiantes que pasaron por la Universidad Icesi, un equipo de profesores y estudiantes modeladores incorporaron al libro un componente de animación en 3D y sonido por medio de la combinación de realidad aumentada e inteligencia artificial. Así, el lector podrá aventurarse en un mundo tridimensional en donde el ave cobra vida, vuela y canta. En este libro se combinan las técnicas clásicas del arte milenario del dibujo científico con la innovación tecnológica de la realidad aumentada para despertar el interés de todas las personas que conviven con estas aves en la ciudad más ornitodiversa del mundo y promover su conservación.
