Поперечные градиенты продольного магнитного поля в активных областях с разным уровнем вспышечной продуктивности. II. Статистический анализ
Authors: Фурсяк Ю. А.
Published: April 2024

Работа является частью исследования, посвященного изучению градиентов продольного магнитного поля в активных областях (АО) с разным уровнем вспышечной продуктивности. Выполнен статистический анализ параметров, описывающих поперечную составляющую градиента продольного магнитного поля z B   в АО: средней по области величины поперечной составляющей градиента продольного магнитного поля z B   , средней величины z B   в окрестности точки с максимальным его значением max Bz , максимального значения z B   между парами пятен в АО z sp max ( B )   . Для вычисления обозначенных параметров использованы магнитограммы z B -компоненты вектора магнитного поля на уровне фотосферы Солнца, получаемые инструментом Helioseismic and Magnetic Imager (HMI) на борту Solar Dynamics Observatory (SDO). Статистическая выборка содержит в себе данные о 75 АО. Усредненные за время мониторинга величины анализируемых параметров сопоставлены с уровнем вспышечной продуктивности АО (вспышечным индексом, FI). Показано, что: 1. Зависимость z B   - FI (чертой сверху обозначено усреднение по времени мониторинга АО) квадратичная с коэффициентом корреляции k = 0.54, а разброс значений величины z B   небольшой (для подавляющего большинства исследуемых областей находится в пределах 0.08-0.12 Гс км-1) и крайне мало различается для областей с низкой и высокой вспышечной продуктивностью, что можно объяснить зависимостью величины z B   от площади АО. 2. Зависимость z B  max - FI квазилинейная с коэффициентом корреляции k = 0.61. 3. Зависимость z sp max ( B )   - FI линейная с коэффициентом корреляции k = 0.63. 4. Выявлены пороговые значения анализируемых параметров: для величины B 0.078 z    Гс км-1, для величины max B 0.983 z    Гс км-1, для параметра max ( B ) 0.118 z sp    Гс км-1. При более низких значениях анализируемых параметров ни в одной из областей выборки вспышек рентгеновских классов Х не фиксировалось.

The impact of ESG on management tone: Empirical evidence from China
Authors: Hu Ying , Zhang Xuanming
Published: April 2024

This paper examines the effect and mechanism of ESG (Environmental, Social, and Governance) performance on management tone from the perspective of psychology and behavioral finance. The study found that ESG performance can significantly improve the enthusiasm of managers’ intonation, which is more obvious when the population density of the enterprise is higher. The mechanism analysis shows that the ESG performance of enterprises mainly affects the tone of managers through two channels: reducing financing constraints and improving financial performance. This paper examines the internal logic of ESG practice on managers’ emotional tendencies from the perspective of psychology and behavioral finance, and reveals that ESG practice does not make managers become negative.

Authors: Nguyen Ngoc Tri Huynh , Nguyen Thanh Thien , Nguyen Pham Huong Huyen , Nguyen Khanh Son
Published: April 2024

The bio-cementation process through bacterial mineralization has emerged as an eco-friendly solution for soft or loose sandy soils, particularly in areas with ground slopes and high rainfall. This approach is aligned with sustainable development goals, promoting environmentally responsible and long-lasting solutions. In this context, ureolytic bacteria capable of decomposing urea for calcium carbonate precipitation are the primary agents for bio-cementation. This study explores the effects of nano calcite as nucleation sites on the MICP capacity to enhance the bio-cementation process. The microstructure of the precipitation was analyzed alongside its capacity for MICP. In addition, a simulated rainfall model was set up to evaluate the erosion resistance of sand samples. The findings of this study can guide the development of eco-friendly solutions for soil stabilization in environmentally vulnerable areas.

Violencia de masas y radicalización de la estrategia bélica japonesa en el Sudeste Asiático, 1942-1945
Authors: Maddox Kelly
Published: April 2024

Los episodios de violencia de masas salpicaron la ocupación japonesa del Sudeste Asiático entre 1942 y 1945. Aquí examino dos de esos casos: la «purga» de la población china de Singapur tras su captura en febrero de 1942 y las masacres de civiles durante la campaña antiguerrillera en Panay en 1943. Sostengo que estos episodios estaban enraizados en una estrategia militar que posibilitaba el uso de la fuerza como la táctica principal en la gestión de las ocupaciones y que la intermitente escalada de esta estrategia violenta fue contingente a una serie de elementos que condicionaron la toma de decisiones sobre el terreno, facilitando la tolerancia hacia medidas más extremas en la consecución de los objetivos militares.
Mercenarios blancos entre el Congo y Nigeria: neocolonialismo y contrainsurgencia en África Central durante la Guerra Fría, 1960-1970
Authors: Alonso Ibarra Miguel , Alegre Lorenz David
Published: April 2024

En este artículo analizamos algunos de los límites y particularidades del proceso de descolonización en África Central durante los años sesenta, tomando como sujeto de estudio a los mercenarios blancos que participaron en las guerras civiles del Congo (Katanga) y Nigeria (Biafra). El impacto de sus actividades, sus conexiones político-económicas internacionales, sus fuentes de reclutamiento, sus motivaciones y sus creencias, las relaciones entre los diferentes colectivos o el conflicto entre sus agendas y las de sus promotores nos hablan de una descolonización congelada, de la circulación transnacional de praxis y discursos contrainsurgentes y de una extrema derecha global que mantendría importantes conexiones con los antiguos centros de poder metropolitanos. Así pues, nos proponemos profundizar en el despliegue de nuevas formas de poder, control e injerencia en el África postcolonial por parte de las potencias occidentales y los grupos de intereses dentro de estas.
Zanzibar’s spice forests: Restoring the Spice Islands
Authors: Jacobs Rebecca
Published: April 2024

Spice farming in Zanzibar has been integral to the country’s culture, history and economy but in recent decades, Zanzibar’s role in the global spice trade has diminished as declining market prices and government interference have pushed many farmers to convert spice forests into monoculture farms. Community Forests International (CFI) and Community Forests Pemba (CFP) have been working since 2015 to re-establish these diverse agroforest ecosystems and restore farmers’ livelihoods. Unlike monoculture farming, spice forests offer better economic incentives, ecological sustainability, and equality for women, and have the potential to restore a resilient spice-farming economy that is ecologically and socially sustainable. By revitalising local and indigenous knowledge, including from Tanzania, agroforestry practices are being implemented by small-scale Zanzibari farmers to grow a mix of timber, fruit and spice tree crops. This has enabled farmers to improve their household nutrition, increase their crop yields and diversify their income streams, ensuring energy, food and income security. The use of agroforestry practices in spice forests has also promoted structural and ecological diversity, regenerated soil health, enhanced carbon stores, and ensured resilience against climate change. Stories of individual farmers, Saidi Khalifa and Kibano Omar Kibano, exemplify how landscapes and lives can be positively transformed when spice forests are restored to replace monoculture farms with training and support from CFP. The story of Bimajo Masoud Juma also exemplifies how CFP has promoted agroforestry to empower women to have an independently earned income, ensuring their economic independence. CFP is also working with farmers to create stronger cooperative models that would enable them to sell directly to international buyers. The global organic spice market is expanding, so farmers involved in these sustainable and organic agroforestry practices are well-positioned to thrive.

Published: April 2024

It is enough to get acquainted with the expressions of recognized authorities to understand that universal absolute values are born over time, which are only national in origin. They turn into a cultural language that everyone can understand, with which any thought and mood can be expressed, and which, of course, does not need a translator. It is in this sense that cultural diplomacy becomes easier, which does not require additional explanations and interpretations. With its universal perception, it can only serve universal values: peace, friendship, cooperation, etc. It is important to note that the factor of cultural diplomacy directly addresses the interconnected problems of mutual understanding, stability and development, and as such provides a reliable starting point for a fruitful work. Finally, cultural diplomacy contributes to the national brand, the process of improving the overall environment to establish peace, increase the level of competetitiveness of nations in the global economy.
THE MAIN PROBLEM OF POPULATION AGING IN THE REPUBLIC OF
ARTSAKH DURING THE YEARS OF INDEPENDENCE
Authors: MINASYAN Manush
Published: April 2024

Population aging is visible worldwide. It is a systemic phenomenon that touches all
spheres of life at the level of the individual, the household and the entire society. Observations show that the process of demographic aging is a consequence of long-term demographic changes, changes in birth rates, deaths and their ratios, acceleration of labor migration. The purpose of the article is to evaluate and analyze the population aging process in the Republic of Artsakh in 2010-2022. In order to achieve that goal, we have asked to study the trend of demographic indicators, especially those related to aging, to identify the factors affecting it, to make a comparison with the relevant indicators of other countries. Statistical analytical methods were used. The rate of demographic aging in the USA (the weight of people aged 65 and older in the total population) in 2022. 2010 compared to, on average, it decreased annually by 0.04-% point and in 2022 made 11.9%, and according to the Rosette scale by 0.01% point, making 16.3%. During the 30 years of independence, due to the insufficient birth rate and migration (in some years it had a negative balance), there was no significant increase in the population of the Republic of Azerbaijan. Citizens of reproductive working age (age group 20-49) made up the main part of emigrants, which significantly affected not only demographic aging, but also changes in the sex-age structure of the population and a decrease in the birth rate.
The Karzai Administration: Challenges, Achievements, and Controversies
Authors: Dashti Sahib Nazr
Published: April 2024

In October 2004, Karzai assumed the presidency through a constitutional mandate, raising hopes for political stability, ethnic reconciliation, and effective governance. However, his tenure was marred by entrenched political rivalries, ethnic tensions, governance challenges, military escalations, and rampant corruption, which overshadowed his ability to fulfill the promises of his presidency. This article aims to analyze the political legacy of Hamid Karzai's thirteen-year rule, shedding light on his governance approach and unmet commitments. Despite initial expectations of strong leadership, Karzai's tenure was marked by persistent political discord, ethnic fragmentation, and governance deficiencies. While his presidency achieved significant milestones, such as constitutional reforms and electoral processes, it fell short in addressing systemic issues, including corruption and security concerns. Through an examination of Karzai's political trajectory, this article seeks to illuminate the complexities of governing Afghanistan amidst formidable challenges, ultimately evaluating the effectiveness of his leadership during a tumultuous era of transition and turmoil.
Short-Term Electrical Energy Demand Forecasting Using Fuzzy Logic Technique
Authors: Antigha Ita Maurice
Published: April 2024

Minimization of electrical energy wastage and provision of its regular supply make electrical load forecasting an important aspect of the power infrastructure. An accurate load forecasting is crucial for the reduction of the cost of electrical energy generation and spinning reserve capacity. Therefore, in this study, fuzzy logic (FL) technique was employed for the projection of electrical energy demand on short-term basis. The FL model was trained using the six months hourly load and temperature data respectively obtained from 132/33 kV Ikeja West Transmission Station, Ayobo and Nigerian Meteorological Agency, Oshodi, Lagos State, Nigeria. Triangular and trapezoidal membership functions (MFs) were used in the training of the model with Mamdani fuzzy inference system. The time, load and temperature inputs were fuzzified into six, four and three MFs respectively while the fuzzification process used 25 fuzzy rule bases. The centroid method of defuzzification was used to change the results into readable values. The adequacy of the FL model was determined using five metrics including mean square error (MSE), mean absolute error (MAE), mean absolute percentage error (MAPE), chi square (χ2) and F- test. The obtained results revealed that the FL model developed excelled in all the five tests of adequacy considered with MSE, MAE, MAPE, χ2 and F-test values of 4.17, 6.74, 11.51%, 7.93 and 1.27 respectively and hence, performed satisfactorily. This work established that the fuzzy logic approach is appropriate for electrical load projection on short-term basis.
Application of Static Synchronous Compensator for Improvement of Power System Transient Stability
Authors: P Olaogun
Published: April 2024

Transient stability is the power system’s ability to maintain synchronism when exposed to severe disturbances such as loss of generation, rapid load changes, transmission lines tripping, switching operations and faults. Transient instability causes cascading outages, system collapse and economical losses. This study employed static synchronous compensator (STATCOM) for power system transient stability improvement. The system’s steady state and transient responses were respectively modelled with Newton-Raphson power flow and modified-Euler linearized swing equations. A balanced three-phased short circuit fault was introduced on selected buses for transient stability analysis. The steady state and transient responses of the system were simulated with and without STATCOM. The critical fault clearing time (CFCT) was obtained from the generators’ swing curves. The IEEE 9-bus and 14-bus power networks were used as test cases. The voltage magnitudes of all buses in both networks fell within the specified 0.95 to 1.1 p.u. voltage limit with and without compensation. The total active line loss on IEEE 9-bus and 14-bus networks which were 4.641 and 13.514 MW without compensation reduced to 4.600 and 13.014 MW, respectively with STATCOM’s application. The total reactive line losses of both networks which were 92.160 and 31.393 MVAr without compensation decreased to 90.160 and 30.693 MVAr, respectively with STATCOM’ utilization. The CFCT for fault on bus 8 of the IEEE 9-bus system without compensation were 0.2100 and 0.2700 s for generators 2 and 3, respectively. The system’s stability was, however, extended beyond 0.2700 s due to compensation from STATCOM. In the case of IEEE 14-bus system, the CFCT for fault on bus 6 was 0.36364 s for generators 2, 3, 4 and 5, respectively without compensation. The STATCOM inclusion, however, enhanced the system’s stability beyond 0.36366 s where all the four had lost synchronism. This work established that the use of STATCOM on the considered networks appropriately extended the CFCT such that the stability of the systems was not lost in the event of fault application via robust compensation of reactive power.
Acaricidal Efficacy of Cassia sieberiana DC (Caesalpinaceae) Stem Bark Aqueous Extract on Hyalomma KOCH, 1844 (Acari: Ixodidae) Reproductive Stages
Authors: AB Abdullahi
Published: April 2024

One of the most significant challenges facing tick control through chemical acaricides is resistance and environmental pollution, encouraging the need for natural plant products that are less toxic and environment friendly. This study was conducted to determine theacaricidal efficacy of Cassia sieberiana stem bark aqueous extract on Hyalomma species using immersion testing for egg-hatchinhibition and adult mortality. Both tests used ascending extract concentrations of 5%, 10%, 15% and 20%, at durations of 1, 2, 3, 4, 5, 6, 7 and 8 hours. Egg-hatch inhibition peaked at 5% concentration at 8hrs, 10% and 15% at 7 and 8hrs and 20% at 5, 6, 7 and 8hrs while adult mortality was highest at 20% concentration. There was a positive correlation between graded extract concentration, immersion period, egg-hatch inhibition and adult mortality. The LC50 values for adult mortality and egg-hatch inhibition were 13.1 mg/mL and 13.7 mg/mL and coefficient of determination were y = 3.7x +1.5 and y = 3.062 + 8.12 respectively. Both LC50 values were almost similar indicating a strong association between extract concentration and acaricidal activity in vitro.

In recent years, Ulaanbaatar, the capital of Mongolia, has experienced very rapid urbanization. Different reasons are considered for urban expansion, however, the main cause is connected with a mass movement of rural people seeking for improved living conditions. The aim of this study is to analyse changes in urban land use in the central part of the capital city using remote sensing (RS) and geographic information system (GIS) datasets. For the development of the principal digital spatial database, a 1:5000 scale topographic map and a historical description of the elements of land use were used. To update the database and extract reliable urban land use information, very high-resolution panchromatic and multispectral Quickbird images of 2023 were fused. For fusion, three different data fusion techniques such as a Brovey transform, Gramme-Schmidt method and intensity-hue-saturation (IHS) transformation were compared in terms of the enhancement of spatial and spectral variations of the available classes. Of these methods, the IHS transformation gave a superior result in terms of both spectral and spatial separations between different objects and classes. Therefore, for this technique was selected for further analysis. Overall, the research showed that the central part of Ulaanbaatar city became very dense and precise planning should be considered.

Authors: Batchuluun Ganbayar , Tserendondog Tengis
Published: April 2024

Following the constitutional provision stating that “Mongolia has an armed force for self-defence” [1], and fulfilling its duty to safeguard its territory, borders, and national security, the technical equipment of the radar station, which monitors the current airspace, is undergoing rapid development. This involves updating and improving the system, as well as transitioning from analogue to digital, with the automation process progressing swiftly day by day. For Mongolia, it is very important to determine the angle of rotation of the radar antenna used in the armament of the Air Force of the Armed Forces and determine the target detected in the airspace. This paper introduces a novel hardware and software solution for simulating the control of a radar antenna rotation system and processing the output signal of a Selsin sensor to determine the rotation angle. Due to the confidentiality of military information, this article does not include device brands, specifications or bibliography.

Development of diagnostic parameters for assessing the operation of a diesel engine on site
Authors: Sandag Galbadrakh , Jamyan-Osor Purevsuren , Natsag Odgerel
Published: April 2024

The paper aims to develop the on-site diagnostic parameters for assessing the operation of engines through the content (g/ton) of wear elements and contaminants in used oil.  Here, it refers to heavy-machinery vehicles used in various industries of Mongolia such as agriculture, railway, building and road construction, mining etc. This study analyzed the results of measurements in the used oil samples from 20 diesel engines over a maintenance period of 5-6 years using spectral analysis. It focuses on three key goals: determining the content of wear elements and contaminants in used oil (g/ton), studying the intensity of engine wear during one period of maintenance, and using non-parametric statistical methods to develop the on-site diagnostic parameters based on the concentration of wear elements and contaminants in the samples of used oil.

The diagnostic parameters determined as a result of this study can enable technicians to perform diesel engine maintenance based on the actual technical condition of the engine, rather than relying solely on the manufacturer's recommended maintenance schedule, reduce the repair cost by addressing the aspects before serious breakdowns or delays occur and improve overall the engine performance, resulting in significant benefits for the transportation and heavy-machinery industries.

O presente texto faz parte das discussões de pesquisa cientifica em andamento, que tem como objetivo analisar a participação do setor Agropecuário para com as políticas sociais no país, tendo como recorte temporal, do ano de 2013 até 2022. Destas reflexões em nível nacional, nasceu a ideia de fazer alguns apontamentos analíticos da região Sul do Brasil, partindo da mesma base de estudo e recorte temporal. Para tanto, buscou-se entender as transformações socioeconômicas da região investigada, relacionando com o desenvolvimento histórico, social e econômico nacional, desde o período colonial até o momento atual, para entender, mesmo que de forma sintética a construção socioeconômica no Sul do Brasil. Para depois, ir no objeto de análise do presente trabalho, que é demonstrar os dados da contribuição do PIB do setor agropecuário dos três Estados que abrangem a região, bem como a participação do setor no financiamento do Crédito Rural e por fim, qual a fração efetiva da Agropecuária nas receitas liquidas nos Estados. Para a realização desse trabalho seguiu-se alguns passos metodológicos, de: levantamento primário de dados em sites oficiais (portal da transparência e das receitas estaduais), de documentos oficiais (relatórios, orientações, leis e outros) e, levantamento bibliográfico da temática estudada.

Published: April 2024

O presente artigo busca tratar sobre a relação dos conceitos de vulnerabilidade social, negócios de impacto e empreendedorismo. Com o intuito de entender a problematização: Como o empreendedorismo social e a inovação social podem contribuir para a redução da vulnerabilidade social? Para isso, conta com pesquisas bibliográficas em artigos, revistas e livros que tratam sobre os conceitos, bem como a pesquisa exploratória através do reconhecimento de 15 negócios de impacto que atuam em território brasileiro, com o objetivo de conhecer as empresas e identificar o impacto que estas empresas causam na região em que se localizam. Para isso foram utilizados requisitos como: (I) Ramo de atividade; (II) Estado de atuação; (III) Descrição sobre a atuação; e (IV) exposição sobre a vulnerabilidade social associada, como forma de conhecer as empresas. Concluiu-se em relação aos requisitos das empresas pesquisadas que a maioria atua no ramo de serviços, localizadas em maior parte no Estado de São Paulo (53%). Já em relação à vulnerabilidade associada, considera-se que são diversas ligadas a saúde, a mobilidade, a questões raciais e questões de gênero. Neste sentido frisamos as limitações encontradas no estudo, tais como: o conhecimento raso sobre as vulnerabilidades relacionadas às localidades, onde sugere-se análises mais profundas para identificar o impacto que estas empresas causam na melhora da qualidade de vida da sociedade. Bem como em relação aos sites disponíveis, limitações sobre a motivação dos negócios e o público efetivamente alcançado. Como tais limitações relacionam-se estreitamente com o conceito de impacto social, propõe-se, um estudo, baseado em saídas de campo, para conhecer e analisar os negócios de impacto de forma efetiva, ou seja, reconhecendo seu impacto sobre a sociedade.
