In the scientific field remote sensing as a research tool in the lowland steppes focuses on monitoring vegetation to assess the extent of desertification. However, monitoring individual glaciers would significantly increase the accuracy of the criteria for forecasting areas at risk. This study uses the latest methodology for monitoring glaciers using satellite images of the East Kazakhstan region (Kazakhstan). The approach involves comparing the characteristics (area) of glaciers on satellite images (TM) over a 6-year period (2016, 2019 and 2022). According to the data obtained, the author compared the size of the Berel glacier, which is one of the sources for maintaining the water supply level

Координаталарды анықтаудың жерсеріктік технологияларын іске асыру жер қойнауын игеру кезінде геодезиялық негіз құру және кеніштерде маркшейдерлік-геодезиялық жұмыстарды жүргізу үшін жаңа мүмкіндіктер ашады. Осыған байланысты эллипсоидтың бетінде автоматтандырылған әдіспен алынған координаттарды қалыпты тік сызыққа бағытталған көлденең жергілікті проекцияға аударудың маңызы өте зор.

The introduction of satellite technologies for determining coordinates opens up new opportunities both for creating a geodetic basis for the development of the subsoil, and for the production of surveying and geodetic works at mines. In this regard, it seems very promising to transfer the coordinates obtained by an automated method on the surface of an ellipsoid to a horizontal local projection oriented normally to a vertical line. Such an approach to the creation of a geodynamic polygon (GDP) during the development of the subsoil will certainly make it possible to more accurately make design decisions in kind. The article proposes an up-to-date approach to the formation of a geodynamic polygon, which consists in the use of a local flat surface with topocentric coordinates. Calculations and concrete examples of the translation of coordinates from a geocentric system to a topocentric one are given, in which the measurement results are equalized

Внедрение в жизнь спутниковых технологий определения координат открывает новые возможности как для создания геодезической основы при освоении недр, так и производства маркшейдерско-геодезических работ на рудниках. В этой связи представляется весьма перспективным перевод координат, получаемых автоматизированным способом на поверхности эллипсоида, на горизонтальную локальную проекцию, ориентированную нормально отвесной линии.Такой подход к созданию геодинамического полигона (ГДП) при освоении недр безусловно позволит точнее выносить проектные решения в натуру. В статье предложен актуальный подход к формированию геодинамического полигона, заключающийся в применении локальной плоской поверхности с топоцентрическими координатами. Приводятся выкладки и конкретные примеры перевода координат из геоцентрической системы в топоцентрическую, в которой производится уравнивание результатов измерений

В данной статье рассмотрен способ крепления вентиляционного шурфа на месторождении Жаман-Айбат, Карагандинской области, т.к. в настоящее время стенки шурфа остаются незакрепленными. В условиях рудника Жомарт шурфы были пройдены задолго до возведения крепи, поэтому секционный способ крепления не может быть реализован для горных выработок. Исходя из зависимости параметров крепи основной части ствола, от действующих в массиве напряжений, выполняется оценка напряженно-деформированного состояния. Для данного рудника определена длина анкеров и расстояние между ними. Определена технология крепления бортов и устьев шурфов, расчитаны длина анкеров и толщина торкретбетона. Крепь шурфа должна состоять из двух частей: возле устья закреплена монолитной железобетонной крепью и основную часть ствола рекомендуется крепить комбинированной крепью

Бұл мақалада Қарағанды облысы, Жаманай-Айбат кен орнында желдеткіш шурфты бекіту әдісі қарастырылған, себебі қазіргі уақытта шурфтың қабырғалары бекітілмеген күйінде қалып отыр. Жомарт кенішінің жағдайында шурфтар бекіткіш тұрғызылғанға дейін ұзақ уақыт өткен, сондықтан секциялық бекіту әдісін тау-кен қазбалары үшін іске асыру мүмкін емес. Магистральдың негізгі бөлігін бекіту параметрлерінің массивтегі кернеулерге тәуелділігіне сүйене отырып, кернеулі деформацияланған күйді бағалау жүргізіледі. Бұл кеніш үшін якорьдің ұзындығы және олардың арасындағы қашықтық анықталады. Шурфтардың бүйірлері мен сағаларын бекіту технологиясы анықталды, якорьдің ұзындығы мен бетон торкретінің қалыңдығы есептелді. Шурфтың бекіткіші екі бөліктен тұруы керек: сағаның жанында монолитті темірбетон бекіткішпен бекітілген және магистральдың негізгі бөлігін біріктірілген бекіткішпен бекіту ұсынылады

This article discusses the method of fixing the ventilation pit at the Zhaman-Aybat deposit, Karaganda region, because at present the walls of the pit remain not fixed. In the conditions of the Zhomart mine, the pits were passed long before the construction of the support, so the sectional method of fastening cannot be implemented for mining. Based on the dependence of the parameters of the support of the main part of the trunk on the stresses acting in the array, the stress-strain state is evaluated. The length of the anchors and the distance between them are determined for this mine. The technology of fixing the sides and mouths of the pits is determined, the length of the anchors and the thickness of the shotcrete concrete are calculated. The pit support should consist of two parts: it is fixed near the mouth with a monolithic reinforced concrete support and it is recommended to attach the main part of the trunk with a combined support

Metadados para a construção de coleções especiais: a coleção Art by Female Artists
Authors: Mendonça Ana Carolina Novaes de , Arakaki Felipe Augusto
Published: July 2024

Objetivo: A Biblioteca Digital Europeana foi desenvolvida pelos países da União Europeia com o intuito de oferecer acesso online gratuito a patrimônios culturais provenientes de instituições como museus, bibliotecas e arquivos. Para tanto, a Europeana desenvolveu o Europeana Data Model (EDM) — um modelo interoperável para coletar, conectar e enriquecer metadados do patrimônio cultural — e adotou práticas de Linked Data em seu catálogo, garantindo a interoperabilidade. Discutir a importância dos metadados para auxiliar a construção e a curadoria de coleções temáticas
Método: Esta é uma revisão bibliográfica que objetiva compreender os conceitos de dados, metadados, Linked data e Linked open data, assim como as documentações técnicas e qualitativas da Europeana, visando explorar e identificar a relação entre as temáticas dentro de uma coleção de obras de arte de mulheres.
Resultados: De maneira geral, os metadados provenientes das instituições são reaproveitados pela Europeana.
Conclusões: Contudo, nem sempre é simples reaproveitá-los, pois criar metadados interoperáveis com qualidade e consistência é uma tarefa que exige investimento, especialização e ferramentas adequadas. Ademais, a ausência de metadados de gênero dificulta a criação e curadoria de coleções especiais, como o agrupamento de obras de artistas do gênero feminino conforme o caso exposto, pois a ausência desses metadados impossibilita a separação dos artistas por gênero, diminuindo assim a diversidade em coleções em instituições culturais.
Entrevista a Youssef El Maimouni
Authors: El Morabit Sghire Zahra
Published: July 2024

Youssef El Maimouni, autor de las novelas Cuando los montes caminen (2021) y Nadie salva a las rosas (2023), nos acompaña hoy para hablar sobre su trayectoria y sus obras. En Cuando los montes caminen, El Maimouni nos ofrece una desgarradora novela histórica ambientada en la Guerra Civil Española, donde seguimos a Yusuf Albartugui, un joven marroquí que se alista en las tropas moras del ejército de Franco y descubre las crueles realidades de la guerra y la opresión. Por otro lado, Nadie salva a las rosas es un thriller contemporáneo que se mueve entre Casablanca y Barcelona, y aborda temas de discriminación y violencia a través de la trágica historia de Rihanna, una joven trans marroquí brutalmente asesinada. Inspirado por autores como Mohamed Chukri, Youssef encontró en la escritura una manera de explorar y expresar las complejidades de las identidades transfronterizas. Su dedicación no solo se refleja en su obra literaria, sino también en su labor profesional como educador social, trabajando en proyectos para jóvenes. Ambas novelas forman parte de la trilogía de la discriminación, un conjunto de obras que exploran las experiencias de la diáspora y el entorno multicultural.
The Ego Conquiro as the Paradigm of Modern Imperialism and its Violence Against the Struggle for Epistemic Justice
Authors: Stromback Dennis L
Published: July 2024

This article begins with a discussion of the implications of Enrique Dussel’s “I conquer, therefore I am” (ego conquiro) thesis as the paradigm of modern imperialism. According to Dussel, underlying the “myth of modernity” (mito de la modernidad) is an epistemological structure of a substantive ego that naturalizes European colonial expansion. Dussel admits that the “I conquer, therefore, I am” thesis began earlier than Descartes’s account of the cogito, which was theorized after the Spanish colonization of the Americas, but the substantive “I” that constitutes the ego conquiro nonetheless represents a theory of knowledge that served and continues to serve the political domination of bodies that have been historically victimized. Couched within the epistemic structure of Descartes’s cogito is a duality between soul and matter, where the former represents an immortal substance detached from the body, taken to be the recipe for rational truth, while the latter is reduced to a quantifiable object occupying a “zero-point” geometrical space. But the cogito became the epistemological standpoint that allowed for the justification of the many hidden forms of domination around the world, because it masks the social, economic, and geopolitical contexts and their history to the modern subject. This article will investigate the ego conquiro thesis and its link to epistemic violence, namely, epistemic racism and epistemicide, and will argue as a concluding point for a method of resistance that foregrounds philosophical pluralism to disrupt the internalization of the epistemologies of the Global North as the common-sense position(s) of today.
Espectadores viajeros: La cinegrafía como herramienta narrativa en las obras de Alberto Fuguet y Antonio José Ponte
Authors: Robles Rojo
Published: July 2024

La cinegrafía es una técnica literaria que combina elementos visuales del cine con las capacidades narrativas de la ficción escrita. Este método crea obras que fomentan un diálogo entre el cine y la literatura. La cinegrafía incluye una metodología literaria que abarca la visualización, la experimentación y el cuestionamiento de la cultura cinematográfica. En este artículo, se examinan modos cinegráficos en la ficción latinoamericana, enfocándose en el trabajo de dos autores contemporáneos: Alberto Fuguet de Chile y Antonio José Ponte de Cuba. En Las películas de mi vida (2003) de Fuguet y La fiesta vigilada (2007) de Ponte, la cinegrafía se emplea para reflexionar sobre la representación cultural en contextos migratorios y políticos. Ambos escritores utilizan sus experiencias personales e introspectivas para explorar las relaciones entre el cine, la identidad y la sociedad.
Chile como “tierra de promisión” para españoles en Diario de un emigrante, de Miguel Delibes
Authors: Salazar Yovany , Leon Marcelo
Published: July 2024

Se propone analizar la representación del proceso emigratorio España - Chile - España en la novela Diario de un emigrante (1958) de Miguel Delibes (1920-2010). Después de efectuar una somera reseña biobibliográfica del escritor, con ejemplos extraídos de la ficción novelesca en estudio, el contenido del artículo se distribuye en seis apartados, en los que se refiere la recreación literaria de los factores causales de la emigración de españoles hacia Chile, las actividades laborales que desempeñan el protagonista y su esposa en el país de destino, los recuerdos que asedian a los emigrantes mientras permanecen fuera del solar nativo; la nostalgia por el lugar de origen y los seres queridos que permanecen en él, las reflexiones sobre la pertinencia del viaje emigratorio y el deseo de retornar. Dicha aspiración solo logra concretarse al término de la novela, lo que evidencia una fecunda recreación literaria del fenómeno sociológico que le sirvió de base.Las problemáticas sociales derivadas del movimiento de personas motivan que algunos novelistas españoles, de similar manera a lo que ocurre con los nacionales de otros países, en sus creaciones narrativas aborden, de una manera directa o tangencial, el fenómeno sociológico de la migración y lo hacen como parte de una tendencia literaria propia de los años cincuenta “cuando el neorrealismo evolucionó hacia un realismo de denuncia social, está cumplidamente demostrada la voluntad de los novelistas por testimoniar la realidad cotidiana que los periódicos, sometidos con rigor a la censura previa, no estaban en condiciones de difundir” (Villanueva).
Ecos del Quijote en Cuando a Guinea se iba por mar (2019) de Juan Tomás Ávila Laurel
Authors: Williams Rachel C
Published: July 2024

Juan Tomás Ávila Laurel, en su novela Cuando a Guinea se iba por mar (2019), crea una versión nueva del clásico español, Don Quijote; en lugar de La Mancha durante el siglo XVI, estamos en Guinea Ecuatorial en los años cincuenta, hacia finales del periodo colonial español en ese país. En este ensayo, argumento que el uso de la ironía, las historias intercaladas y el “héroe” tan inepto que hace de protagonista en el libro de Ávila Laurel son ecos directos e intencionados de la obra cervantina, ahora traspasados a una geografía africana y un contexto colonial. Esta reflexión analiza elementos de la obra de Ávila Laurel para concluir que en Cuando a Guinea se iba por mar se lleva a cabo un proceso de apropiación, con fines transgresores, de la novela cervantina. A través de esta apropiación, el autor realiza una inversión del concepto de una literatura canónica en español, que siempre favorece a la literatura peninsular, especialmente del llamado Siglo de Oro. Precisamente este ensayo propone una interpretación nueva del legado de Don Quijote en la literatura hispanoafricana y, de manera más ambiciosa, sugiere la necesidad de enmarcar los estudios cervantinos dentro el campo del Global Hispanophone.

The purpose of the study was to examine the prevalence of the Relative Age Effect (RAE) across an international soccer programme in male and female players aged 12 years old to seniors. One hundred forty-five male (age: 18.8 ± 4.6 years; body mass: 68.1 ± 10.2 kg; body height: 177.3 ± 10.5 cm) and 218 female (age: 15.9 ± 4.6 years; body mass: 66.2 ± 10.5 kg; body height: 170.6 ± 8.3 cm) players from a National Association were assessed. All participants were divided into four quartiles: January to March (BQ1), April to June (BQ2), July to September (BQ3), and October to December (BQ4). The results showed that the distributions for all male squads were significantly skewed, with more players than expected from BQ1 in the U-21, U-19, and U-17 and less players than expected from BQ4 in the U-19 squad. The distributions for all female squads showed significantly more players than expected from BQ1 in the U-16 and less players than expected from BQ4 in the U-14 squad. The distributions across the different positions for the male squads combined were significantly skewed with more forward players than expected from BQ1 and less forward and midfielder players than expected from BQ4. For the female squads, there were significantly more BQ1 defenders from the U-16 squad than expected. In conclusion, this study unveils significant disparities in quartile distributions among male and female squads. Moreover, the data emphasize the potential impact of heightened physical demands in certain positions on the RAE.

Published: July 2024

The purpose of the article is to study the influence of factors on the real incomes of the population of Kazakhstan and substantiate priority ways to increase them. Using a factor-correlation analysis of the real monetary income of the population with indicators of nominal monetary income, inflation, and the growth rate of the country's economy, the influence of these indicators on the growth rate of income of the population was revealed. Data from the Bureau of National Statistics from 2010 to 2022 were used. The increase in the minimum wage is recognized as one of the tools for increasing incomes, which will lead to an increase in GDP by demand, and will lead to an increase in the IFO of GDP by demand by 0.24%, provided that real household spending increases by 1%. An increase in household incomes will lead to an increase in demand for consumer goods and services, which will lead to an increase in food prices by 0.14%, provided that real household spending increases by 1%. For the growth of real incomes of the population, it is important to strengthen the business activity of the society. An increase in the contribution of SMEs by 1% will lead to an increase in household incomes by 0.32%. An increase in lending to the economy by 1% will lead to an increase in household incomes by 0.11%. The growth of non-primary exports by 1% will lead to an increase in household incomes by 0.13%.

Well-being, reflecting health, happiness and prosperity, is crucial for quality of life. This study aims to assess the effectiveness of pranayama and mindfulness (vipassana) meditation for improving well-being of university students. In this single-blind randomized control trial, 150 undergraduate students (aged, 18-23 years) were employed. The participants of both genders (male:female = 1:1) were randomly allocated into two groups: yoga (n=75) and control (n=75). The yoga group, engaged in daily 60-min pranayama and mindfulness (vipassana) meditation sessions over a period of ten-weeks, while the control group maintained their regular routine. The participants were assessed for well-being, body mass index, blood pressure and pulse rate using standard measures. Data were analyzed using SPSS 24.0. Repeated measure analyses of variance (RMANOVA) followed by Bonferroni adjusted post hoc analyses have shown that there is a significant improvement in overall well-being (p<0.001) in the yoga group after ten weeks and at follow-up. Additionally, significant changes were observed in biomarkers (BMI and BP) at different stages of the study (p<0.05, in all cases). The findings of this study reveal that the combined practice of pranayama and mindfulness (vipassana) meditation exhibits potential benefits in improving well-being and biomarker outcomes among university students.

The Caribbean: Horizons of Possibilities for a Future without Guarantees
Authors: Hintzen Percy C.
Published: July 2024

Este artigo examina os horizontes de possibilidades para o traçar de um rumo para as Caraíbas em direcção a um futuro sustentável, centrando-se na multiplicidade de ligações em que as pessoas e as instituições da região estão envolvidas. Estas possibilidades, argumenta-se, são forjadas a partir de processos globais que começaram com o colonialismo. Elas baseiam-se numa reformulação das relações regionais, afastando-as das formas de soberania ocidental e dos centros de poder globais euro-americanos. Estão presentes em disposições e organizações institucionais regionais que transcendem as fronteiras moldadas por histórias de colonialismo. Derivam das histórias de resistência anti-colonial da região que impregnaram a consciência popular. E estão contidas na escala global das relações “tricontinentais”, através das quais circulam diferentes formas de rejeição do domínio global euro-americano. O artigo examina o seu potencial para transformar as Caraíbas de forma a maximizar a sustentabilidade ecológica, as condições de subsistência humana e a autonomia regional.

In this study, it was aimed to impact the effect of different post-harvest treatments on the shelf life of banana fruits of 'Dwarf Cavendish' banana cultivar after storage and ripening. 1) Modified atmosphere packaging (MAP), 2) 1-methylcyclopropene (1-MCP) + MAP, 3) Three different treatments (MAP + ethylene absorbent (EA)) were applied and only those using macro-aperture PE packaging were considered as control. Banana fruits were stored at 13°C and 90% RH for 30 days. Quality analyses were performed on samples taken at 10-day intervals. After 30 days of storage, the banana fruits were ripened to the ripeness level of No.3 and quality changes were determined after 4 days of shelf life. The treatments significantly limited the color change, softening of the peel and flesh, increased total soluble solids (TSS), ethylene secretion and respiration rate, especially in the last period of storage compared to the control. Green bananas treated with 1-MCP + MAP showed the best results during storage, but ripening problems were experienced. MAP + EA treatment delayed the coloration of banana fruits, softening of the flesh and increases in the TSS content during shelf life. MAP + EA treatment gave the best results both in terms of storage of banana fruits at green maturity and their resistance after ripening.

This study evaluates the radiation safety implications of electromagnetic field (EMF) from electrical distribution sub-stations in Aguata Local Government Area (LGA), Anambra State, Nigeria, using the EMF meter with a laser distance meter in-situ. Ten (10) locations of 11KV distribution sub-stations were mapped out and used for the study. The results of the in-situ measurement of Electric Field (E) and Magnetic Field (H) were used to evaluate the Power Density (S), Specific Absorption Rate (SAR) and Statistical analysis which includes descriptive statistics, inferential statistical tests (T-test) and graphical analysis to evaluate significant differences of EMF levels between different locations. The EMF emitted by these distribution substations was examined using data from the various locations. The results obtained show that EEDC Office has the highest electric field of 0.6633 V/m, while Oko Road has the second highest of 0.7783 V/m. The magnetic field intensity varies across locations, with Oko Road having the largest of 1.3317 A/m. Power density varied, with Oko Road having the highest 1.0365 W/m2 and Stadium having the lowest 0.1011 W/m2. The Specific Absorption Rate (SAR) ranging from 0.0001 to 0.0005 W/Kg showed consistent rates across locations. The International Commission on Non-Protection of Electromagnetic Fields (ICNIRP) sets EMF exposure regulations from 0-300 GHz at the exposure values of, E = 10,000V/m, H = 4×104 A/m, S = 50W/m2, SAR = 10W/kg. In this study, electric field, magnetic field, power density, and specific absorption rate (SAR) values varied widely between stations, with the magnetic field accounting for 45.25% of total electromagnetic exposure. The exposure to EMF emanating from distribution substations in Aguata LGA does not pose any health effect or any health hazards to the general public comparing the measured data with the standard guideline of ICNIRP.

Abstract. Chemical ionization mass spectrometry (CIMS) is widely used in atmospheric chemistry studies. However, due to the complex interactions between reagent ions and target compounds, chemical understanding remains limited and compound identification difficult. In this study, we apply machine learning to a reference dataset of pesticides in two standard solutions to build a model that can provide insights from CIMS analyses in atmospheric science. The CIMS measurements were performed with an orbitrap mass spectrometer coupled to a thermal desorption multi-scheme chemical ionization inlet unit (TD-MION-MS) with both negative and positive ionization modes utilizing Br-, O2-, H3O+ and (CH3)2COH+ (AceH+) as reagent ions. We then trained two machine learning methods on this data: 1) random forest (RF) for classifying if a pesticide can be detected with CIMS, and 2)  kernel ridge regression (KRR) for predicting the expected CIMS signals. We compared their performance on five different representations of the molecular structure: the topological fingerprint (TopFP), the molecular access system keys (MACCS), a custom descriptor based on standard molecular properties (RDKitPROP), the Coulomb matrix (CM) and the many-body tensor representation (MBTR). The results indicate that MACCS outperforms the other descriptors. Our best classification model reaches a prediction accuracy of 0.85 ± 0.02 and a receiver operating characteristic curve area of 0.91 ± 0.01. Our best regression model reaches an accuracy of 0.44 ± 0.03 logarithmic units of the signal intensity. Subsequent feature importance analysis of the classifiers reveals that the most important structural fragments are NH and OH for the negative ionization schemes and nitrogen-containing groups for the positive ionization schemes.
Technical note: New approach for the determination of N2 fixation rates by coupling a membrane equilibrator to a mass spectrometer on voluntary observing ships
Authors: Iwe Sören , Schmale Oliver , Schneider Bernd
Published: July 2024

Abstract. Nitrogen fixation by cyanobacteria plays an important role in the eutrophication of the Baltic Sea, since it promotes biomass production in the absence of dissolved inorganic nitrogen (DIN). Its contribution to the N budget is of the same order of magnitude as the combined sum of riverine and airborne DIN input, varying between 310 kt-N/yr and 792 kt-N/yr. The vast range is due to interannual variability, significant uncertainties in the various techniques used to determine N2 fixation and in extrapolating local studies to entire basins. To overcome some of the limitations we introduce a new approach using a Gas Equilibrium – Membrane-Inlet Mass Spectrometer (GE-MIMS). A membrane contactor (Liquicel) is utilized to establish gas phase equilibrium for atmospheric gases dissolved in seawater. The mole fractions for N2, Ar and O2 in the gas phase are determined continuously by mass spectrometry and yield the concentration of these gases by multiplication with the total pressure and the respective solubility constants. The results from laboratory tests show that the accuracy (deviation from expected values): N2: 0.20 %, Ar: 0.70 %, O2: 0.20 % and the precision (2 times the absolute standard deviation) N2: 0.05 %, Ar: 0.14 %, O2: 0.11 % is sufficient enough to detect and quantify nitrogen fixation. The e-folding equilibration time is 4.8 min for N2, 3.0 min for Ar and 3.2 min for O2. The GE-MIMS is designed for deployment on a voluntary observing ship (VOS), enabling repeated transects along the same route and providing high temporal and spatial resolution data. Therefore, the method is suitable for offering large-scale records of the surface water N2 depletion and of Ar to account for the air-sea gas exchange. Additional O2 measurements will be utilized to estimate the net community production (NCP) triggered by N2 fixation.
