Herencia colonial. Análisis de Bonó, Dussel y del pensamiento decolonial
Authors: Minaya Julio
Published: June 2024

El examen de las herencias coloniales ha sido un móvil entre autores latinoamericanos, entre ellos Enrique Dussel y los impulsores del pensamiento decolonial. Una categoría central empleada es el eurocentrismo. Como antecedente en el Caribe figura Pedro Francisco Bonó, pensador dominicano que cuestionó al colonialismo español y, posteriormente, al neocolonialismo europeo y estadounidense. El artículo discierne entre colonialismo y colonialidad, y examina la triple relación entre la constitución de Latinoamérica, el surgimiento de la modernidad y la génesis del capitalismo mercantilista. Se está ante temas muy controversiales, como la vigencia del legado colonial y neocolonial en la región. Resulta fácil constatarlo en tradiciones, ideas y prácticas cotidianas, en los espacios privados y públicos. Se muestra el caso dominicano, donde la colonialidad impregna la vida y el Estado nación adoptado. La presente indagación no pretende agotar el tema abordado, el cual amerita un esfuerzo investigativo de mayor calado.

Published: June 2024

The objective of this research is to address the issue of frozen orbits in
charged satellites by incorporating geopotential zonal harmonics up to J6 and
the initial tesseral harmonics. The employed model starts from the first
normalized Hamiltonian to calculate specific sets of long-term frozen orbits for
charged satellites. To explore the frozen orbits acquired, a MATHEMATICA CODE is
developed. The investigation encompasses extensive variations in orbit altitudes
by employing the orbital inclination and argument of periapsis as freezing
parameters. The determined ranges ensuring frozen orbits are derived from the
generated figures. Three-dimensional presentations illustrating the freezing
inclination in relation to eccentricity, argument of periapsis, and semi-major
axis parameters are presented. Additional three-dimensional representations of
the phase space for the eccentricity vector and its projection onto the
nonsingular plane are examined. In all investigated scenarios, the impacts of
electromagnetic (EM) field perturbations on the freezing parameters of a charged
satellite are demonstrated.

O EXERCÍCIO DA ADVOCACIA POR MULHERES NEGRAS E A BUSCA PELA IGUALDADE RACIAL DENTRO DA CARREIRA
Authors: Rodrigues Fernanda Cabral , Silva Ademir da
Published: June 2024

O presente trabalho aborda o universo da advocacia, sendo relatadas as dificuldades encontradas por parte das advogadas negras no exercício diário de sua profissão. A oportunidade de acesso ao Exame de Ordem é de todos os egressos dos cursos de Direito, contudo, a colocação de profissionais, embora capacitadas, pode ser determinada por suas características fenotípicas. Dessa forma, o processo deixa de ser acessível a todos e se transforma em escolhas subjetivas. Assim, o artigo visa entender se existe igualdade racial na carreira advocatícia, bem como os obstáculos enfrentados por advogadas negras em relação ao trabalho e as políticas voltadas à construção de um pensamento antirracista na carreira jurídica. A pesquisa chegou à conclusão de que há desigualdade racial na advocacia, mas que é possível mudar essa realidade, sendo possível transformar o pensamento das pessoas e mostrar que as mulheres negras podem ocupar o espaço que elas quiserem na sociedade e especialmente na advocacia.
On the relationship between the mesospheric sodium layer and the meteoric input function
Authors: Li Yanlin , Huang Tai-Yin , Urbina Julio , Vargas Fabio , Feng Wuhu
Published: June 2024

Abstract. This study examines the relationship between the concentration of atmospheric sodium and its meteoric input function (MIF). We use the measurements from the Colorado State University (CSU) and the Andes Lidar Observatory (ALO) lidar instruments with a new numerical model that includes sodium chemistry in the mesosphere and lower-thermosphere (MLT) region. The model is based on the continuity equation to treat all sodium-bearing species and runs at a high temporal resolution. The model simulation employs data assimilation to compare the MIF inferred from the meteor radiant distribution and the MIF derived from the new sodium chemistry model. The simulation captures the seasonal variability in the sodium number density compared with lidar observations over the CSU site. However, there were discrepancies for the ALO site, which is close to the South Atlantic Anomaly (SAA) region, indicating that it is challenging for the model to capture the observed sodium over the ALO. The CSU site had significantly more lidar observations (27 930 h) than the ALO site (1872 h). The simulation revealed that the uptake of the sodium species on meteoric smoke particles was a critical factor in determining the sodium concentration in the MLT, with the sodium removal rate by uptake found to be approximately 3 times that of the NaHCO3 dimerization. Overall, the study's findings provide valuable information on the correlation between the MIF and the sodium concentration in the MLT region, contributing to a better understanding of the complex dynamics of this region. This knowledge can inform future research and guide the development of more accurate models to enhance our comprehension of the MLT region's behavior.
Underestimation of Anaerobic Decomposition Rates in Sphagnum Litterbag Experiments by the Holocene Peatland Model Depends on Initial Leaching Losses
Authors: Teickner Henning , Pebesma Edzer , Knorr Klaus-Holger
Published: June 2024

Abstract. The Holocene Peatland Model (HPM) is a widely applied model to understand and predict long-term peat accumulation. Here, we test whether the HPM can predict decomposition of available Sphagnum litterbag data along a gradient from oxic to anoxic conditionsand estimate parameter values from the litterbag data. Large uncertainties in available litterbag data allow predictions of the HPM to fit decomposition rates estimated from litterbags by adjusting initial leaching losses and decomposition rates estimated from the litterbag data within the range of their uncertainties. Specifically, with standard parameter values, the HPM assumes larger initial leaching losses and smaller decomposition rates than estimated from the litterbag data alone. Therefore, improved tests of the HPM rely on future litterbag experiments that allow a more accurate estimation of initial leaching losses and decomposition rates. When estimating HPM parameters from the litterbag data and assuming smaller initial leaching losses, our analysis indicates that the HPM with standard parameter values underestimates anaerobic decomposition rates for several species and assumes a too steep decrease of decomposition rates from oxic to anoxic conditions. This may be caused by not considering effects of water table fluctuations on aerobic and anaerobic decomposition rates. Whether the discrepancies are reproducible and the estimated parameter values may be an easy fix to account for effects of water table fluctuations in long-term predictions needs further investigation. Based on previous sensitivity analyses of the HPM, the updated parameter estimates can cause differences in predicted 5000 year C accumulation up to 100 kg m−2.
Cosmogenic 21Ne exposure ages on late Pleistocene moraines in Lassen Volcanic National Park, California, USA
Authors: Tulenko Joseph P. , Balco Greg , Clynne Michael A. , Muffler L. J. Patrick
Published: June 2024

Abstract. We report new cosmogenic 21Ne-in-quartz exposure ages from 18 samples on three distinct moraines deposited in the Lost Creek drainage, approximately 3–7 km down-valley from Lassen Peak in Lassen Volcanic National Park. Although measuring 21Ne in quartz is generally straightforward, accurate 21Ne exposure dating of deposits of late Pleistocene-age is rarely possible due to the significant quantities of non-cosmogenic 21Ne present in most lithologies. Young quartz-bearing volcanic rocks have been observed to be an exception. We take advantage of moraine boulders sourced from the ~28 ka dacite of Lassen Peak to generate a chronology of alpine deglaciation in Lassen Volcanic National Park. Ages from three distinct moraines are in stratigraphic order, ranging ~22–15 ka, and generally agree with other terminal and some recessional moraine ages across the Cascades and Sierra Nevada Range of the western United States. To date, these are among the youngest surfaces ever dated using cosmogenic 21Ne and provide a cost-effective proof-of-concept approach to dating moraines where applicable.

Published: June 2024

Abstract. This paper demonstrates the observation of wind shear and veer directly from the operational response of a wind turbine equipped with blade load sensors. Two independent neural-based observers, one for shear and one for veer, are first trained using a machine-learning approach and then used to produce estimates of these two wind characteristics from measured blade load harmonics. The study is based on a dataset collected at an experimental test site featuring a highly instrumented 8 MW wind turbine, an IEC-compliant (International Electrotechnical Commission) met mast, and a vertical profiling lidar reaching above the rotor top. The present study reports the first demonstration of the measurement of wind veer with this technology and the first validation of shear and veer with respect to lidar measurements spanning the whole rotor height. Results are presented in terms of correlations, exemplary time histories, and aggregated statistical metrics. Measurements of shear and veer produced by the observers are very similar to the ones obtained with the widely adopted profiling lidar while avoiding its complexity and associated costs.

The article examines the role of national specificity of anthroponyms and toponyms in the formation of a multicultural personality. It is known that language preserves culture and passes it on from generation to generation, therefore it plays a significant role in the formation of personality, national character, ethnic community, people, nation. The purpose of the article is to identify the reflection of culture in gaps: using the example of Kazakh anthroponyms and toponyms, which have great potential in the formation of a multicultural (secondary) linguistic personality. Knowledge of the lacunae of a linguistic personality allows you to expand your understanding of the world and better understand the behavior of representatives of other cultures. According to scientists, the culture of the people is clearly reflected in anthroponyms and toponyms that represent the linguistic picture of the world, as well as preserving ethnocultural information in their foundations, which is evidence It’s about the peculiarities of the worldview, worldview, and worldview of the people. In the theoretical part of the article, the research of Yu.N. Karaylov, L.P. Klobukova, V.V. Krasnykh, A.I. Izotov on the formation of a linguistic personality is examined in detail; in the practical part, an analysis is made of the works of the Kazakh scientist T. Dzhanuzakov on the role of names own in cultural and national specifics. The article makes an analysis, compares previously expressed opinions about the meaning of proper names in national-cultural specifics, that the names of people and toponyms are a large component of the ethnic group, representing the way of life, beliefs, historical events, culture of the people, which are an integral part linguistic picture of the world, more Moreover, they directly reflect the historical course of events. The article draws a conclusion about the process of studying any non-native language as a practice of intercultural communication, since every new word or phraseological unit reflects the national culture, which is determined by national consciousness

Effect of Mathematical Games on Senior Secondary School Students’ Achievement in Mathematics According to Gender
Authors: Salami Olajumoke , Spangenberg Erica Dorethea
Published: June 2024

Playing mathematical games helps many senior secondary school students—especially girls—acquire basic mathematical skills, but it can be difficult. Thus, this study examined how gender-related mathematical gameplay affects secondary school students' performance. The design of the study was quasi-experimental. Purposively, a sample of fifty senior secondary school students from the Federal Capital Territory (FCT) of Nigeria's Abuja Council Area was chosen. Using a coin toss, the researcher randomly allocated intact classes to the experimental and control groups. An algebraic achievement test administered before and after the treatment determined the students' achievement level. T-tests, means, and standard deviation were used to analyze the data. According to the study, among students who played mathematics games, female students had a higher mean score than male students. The findings imply that mathematical games enhance mathematics teaching and learning and should thus be encouraged and used by teachers to introduce concepts in mathematics to students at different levels, irrespective of their gender.

Effect of Amplitude and Frequency on the Speed of Sound Waves in Air and Water Using PhET Simulation
Authors: Mulyaningsih Rejeki Sri
Published: June 2024

Sound waves can occur not only in solid medium but also in air and water mediums. The effect of amplitude and frequency on the speed of sound waves differs between air and water mediums. The speed of sound waves cannot be seen with the naked eye. A virtual lab is needed to determine the speed of sound wave propagation. The purpose of this study is to determine the effect of amplitude and frequency on the speed of sound waves in air and water medium. The research method used is a quantitative method by conducting experiments online using the PhET application. PhET is used because it can carry out interactive simulations to facilitate research that cannot be done in real terms, but must make use of an effective virtual lab. The results obtained, namely in the medium of air and water, it is proven that the amplitude and frequency are directly proportional to the speed of sound wave propagation. In conclusion, sound waves travel faster in the water medium than in the air medium. Sound waves travel faster in the water medium because in liquid the particles are closer together than in the air medium, so sound waves will travel faster.

Published: June 2024

On the rice field ecosystem in Cao Lanh district, Dong Thap province, there are 6 species of amphibians distributed: Duttaphrynus melanostictus, Kaloula pulchra and Hylarana guentheri have the most diversity of feed ingredients; Fejervarya limnocharis, Hoplobatrachus rugulosus and Ichthyophis bannanicus have less food diversity; Scolopendomorpha and Polydesmoidea are the least, accounting for 1,2%. Amphibians have the most food frequency in Coleoptera, followed by Hymenoptera and Orthoptera. Amphibians are usually terrestrial, eating mainly insects. The frequency of pests was lowest in the period from sowing seeds until the rice had 3 leaves germinated, the lowest in the period of yellow rice until after harvest, the highest at the stage of rice with milk in the grain to the stage of green - ripened rice. The frequency of encounters of Hoplobatrachus rugulosus and Fejervarya limnocharis is lowest at the stage of seeding until rice germination, decrease gradually in the period of ripe rice until after harvest, stage 4 (Rice with milk in the grain until green ripening) has the highest frequency. In stage 1, there is the lowest frequency of encountering amphibians and pests, frequency increases gradually to stage 2 and peaks at stage 4, decreasing at stage 5.

Changes in land use/land cover (LULC) have a significant impact on the changes in ecosystem service values. This study aims to assess the impacts of LULC changes on provisioning ecosystem services (pES) in the Long Xuyen Quadrangle region (LXQ) from 2000 to 2021.  Using Landsat 5 TM and Landsat 8 OLI imagery, this study analyzes the normalized difference vegetation index (NDVI) time series using MODIS imagery to monitor and evaluate the impacts of LULC changes in the LXQ region. Additionally, interviews with farmers were conducted to estimate the ecosystem service values of different rice cultivation models. The research results in the creation of LULC maps for the LXQ in 2000 and 2021, with relatively high reliability, including overall accuracy (OA) of 83.18% (K = 0.772) and 94.26% (K = 0.9284), respectively. The main LULC change observed in the LXQ region from 2000 to 2021 is the conversion from wetlands to double-cropped rice and triple-cropped rice systems. The study identified an area of 54,667.722 ha (26.24%) where wetlands were converted to double-cropped rice, and an area of 36,779.633 ha (17.65%) where wetlands were converted to triple-cropped rice. Furthermore, the estimated ecosystem service values after the conversion from wetlands to triple-cropped rice were approximately 122,504,931 VND/ha/year, and for double-cropped rice, it was approximately 87,772,604.88 VND/ha/year. The research findings indicate that wetland agriculturalization, including double-cropped rice and triple-cropped rice, has affected the ecosystem service provision in the LXQ region. These research results provide significant considerations for future comprehensive valuation of ecosystem service values in the LXQ, Vietnamese MD.
Schémas de représentations des imaginaires et signifiants culturels et gestion des indices de souffrance psychiqusi dae de l’enfant handicapé en Afrique
Authors:   University of Yaounde 1, Cameroon, BANINDJEL Joachen
Published: June 2024

This research aims to show the impact of patterns of representations of imaginaries and cultural signifiers in the psychic suffering of children living with a disability. Indeed, in traditional African societies, the child occupies a privileged place and status which is inspired by its origins linked to the representations of imaginaries and cultural signifiers, which are related to those of the parents and the community. Despite this status and this place, the child with a disability finds himself
in a difficult situation, because of his deficiency, his incapacity, his difficulty in participating in social life and psychological suffering which are the result of
belonging to two diametrically opposed universes. If in this situation we do not conceive or name the psychic suffering of the child, the imagination and popular
language are nonetheless full of characterizations of the malaise and the suffering of the child. The final situation that emerges from this research is that if psychic
suffering can be considered as an indelible mark in a mentally disturbed and physically inoperative subject, the therapist can, through well-organized ritual
practices, play the role of mediator between the visible world and the invisible world in order to reactivate and revitalize the psychic authorities of the sick subject and
thus facilitate his integration into the society of the living

New technologies have enjoyed a remarkable boom in recent years. Their presence in the institutional environment bears witness to innovative and effective teaching and learning practices. With the adoption of new approaches favoring the transition from a teaching logic to a learning logic, and aiming to train autonomous citizens, the digitization of teaching is becoming a necessity. As a result, the roles of teacher and learner need to adapt to new requirements, making the teacher a learning facilitator and the learner an active member with a key role to play in the construction of his or her knowledge. This leads us, in the context of this work, to question the digital skills available to students to use new technologies responsibly and ethically in their learning. In this contribution, we will also attempt to highlight the main changes brought about by the introduction of digital technology in the language classroom, and its contribution for practitioners and learners alike, without losing sight of the threats it may represent for learners, particularly those relating to ethics.

This paper presents a case study based on student's responses to a survey
applied in an extracurricular project carried out in 2022, who have made study visits,
as an extracurricular activity, to present their role for labour market integration.
Through extracurricular projects, including study visits, students can
discover new equipment and technologies used in companies and identify the
workflow at different workplaces. Study visits provide students with the
opportunity to gain a real-time perspective on the field they aspire to work in and
connect with professionals in that domain, establishing direct contact with various
departments and functions within an organization. The study highlights the need
to identify students' preferences so that activities carried out throughout the years
of study respond as best as possible to their needs.

Liệu biến đổi khí hậu ảnh hưởng trực tiếp đến quyết định di cư? Bằng chứng thực nghiệm tại các quốc gia Đông Nam Á
Authors: Đức Võ Hồng , Hải Huỳnh Hiền
Published: June 2024

Di cư là trở thành mối quan tâm lớn tại các quốc gia ASEAN do những tác động trực tiếp đến cuộc sống và các vấn đề kinh tế xã hội của người dân. Các nghiên cứu về di cư thường ít được tập trung đầy đủ vào khu vực này, đặc biệt là khía cạnh di cư môi trường. Nghiên cứu này được thực hiện nhằm đánh giá tác động của các yếu tố liên quan đến biến đổi khí hậu, bao gồm nhiệt độ, lượng mưa, và phát thải CO2 đến quyết định di cư tại các quốc gia ASEAN từ năm 1990 đến 2020 theo dữ liệu định kỳ mỗi 5 năm. Nghiên cứu sử dụng phương pháp hồi quy GLS, kết hợp với các kỹ thuật đồng tích hợp FMOLS, DOLS và CCR để xem xét tác động của các nhân tố khí hậu và kinh tế xã hội đối với di cư. Kết quả nghiên cứu cho thấy, nhiệt độ và phát thải CO2 có tác động đáng kể làm tăng tình trạng di cư ở các quốc gia ASEAN, trong khi lượng mưa hạn chế di cư. Bên cạnh đó, các yếu tố kinh tế - xã hội như tăng trưởng kinh tế, dân số và đô thị hóa cũng là những yếu tố tác động làm tăng di cư thuần đến các quốc gia ASEAN trong ba thập kỷ qua.

Due to its widespread distribution, the problem of pollen allergy does not lose its relevance for practical healthcare: the variety of clinical forms, the possibility of polyvalent sensitization and pathogenetic treatment in the form of allergen-specific immunotherapy determine the importance of studying its clinical and epidemiological features.

Materials and methods. A retrospective analysis of 119 discharge summaries of children with diagnoses of “Allergic rhinoconjunctivitis”, “Bronchial asthma”, “Atopic dermatitis”, occurring with clinically significant pollen sensitization, was carried out in the period 2015–2022. The prevalence, clinical features, prevailing symptoms and atopic comorbidity of patients with pollen allergy living in the Nizhny Novgorod region were assessed.

Results. Pollen allergy is characterized by a variety of clinical manifestations, which are mainly represented by allergic rhinoconjunctivitis, bronchial asthma, and oral allergic syndrome. In the study, in the majority of patients, polyvalent sensitization was combined with a pronounced variety of products that provoke oral allergic syndrome. Manifestations of pollen allergies requiring seeking medical help are equally distributed among residents of Nizhny Novgorod and the region’s villages.

Conclusions. Clinical and epidemiological features of the course of pollen allergy are of great interest to the practicing physician. The variety of manifestations of pollen allergies determines the need for a clinically effective treatment method, which today is ASIT. One of the needs of modern healthcare is to increase the awareness of primary care physicians about atopic diseases, incl. pollen allergy, with the aim of timely referral of patients to a specialist. Currently, allergen-specific immunotherapy is the most effective method of treating manifestations of pollen allergies.

El paraquat (PQ), es un herbicida altamente tóxico, para lo cual se requiere una rigurosa vigilancia en los alimentos para cumplir con los límites reglamentarios. Este estudio tuvo como propósito cuantificar residuos de PQ en maíz (Zea May L.) por espectrofotometría UV-Visible, en muestras provenientes de fincas ubicadas en la provincia La Vega, República Dominicana. Se optimizó la cantidad de reactivo reductor en soluciones estándar de PQ para obtener un coeficiente de determinación de 0.999 y un rango de linealidad. Los límites de detección y de cuantificación fueron 0.05 y 0.17 mg L-1, respectivamente, con una recuperación del 101.7% y el coeficiente de variación menor al 5%. Por medio de la curva de adición estándar se determinó la concentración de PQ en maíz que fue de 0.56mg L-1, la cual se encuentra dentro de los límites permitidos por la FDA para el consumo humano. Además, se encontró que no existe efecto de matriz, por tanto, se puede utilizar la curva de calibración sencilla para la detección de este analito de manera confiable. A través de la curva de calibración sencilla se encontraron cantidades de PQ en maíz de distintas fincas comparables a la obtenida por la curva de adición estándar. Las pruebas estadísticas F y t -Student no revelaron diferencias significativas entre las concentraciones de PQ en las muestras de maíz de distintas (p>0.05). Este estudio demuestra la viabilidad de la detección precisa de PQ en maíz y su consistencia entre diferentes fincas, asegurando la seguridad alimentaria.
