Atmospheric precipitation acts as a significant pathway for pollutants from the atmosphere to the Earth’s surface, and analyzing urban precipitation data on intensity, fallout regime, transfer patterns, and solid particle content helps identify pollution sources. For the first time in the Moscow megacity, the levels of soluble forms of potentially hazardous elements (PHEs) in atmospheric precipitation were studied during the whole summer season of May–September 2019. The concentrations of Al, As, B, Ba, Be, Bi, Cd, Ce, Co, Cu, Fe, La, Li, Mn, Ni, P, Pb, Rb, Sb, Sn, Sr, and Zn were determined using inductively coupled plasma mass spectrometry and atomic emission spectroscopy methods. The research underscores the crucial role of atmospheric precipitation in washing PHEs out of the atmosphere. In May and September, concentrations of PHEs surpass the warm-season average. Notable contamination in May stems from elevated traffic during vacations, extensive burning of plant debris and wood, and pollen transport. Summer months are characterized by reduced forest and agricultural fires, traffic, and increased vegetation, leading to lower PHE concentrations, especially in July, with typical amount of precipitation contributing to pollutant dispersion. Elevated PHE levels in September are observed due to increased traffic load, biomass burning, and the expansion of unvegetated soil areas. Rainwater is enriched with Sb, Pb, Cd, Zn, Cu, B, Bi, P, and Sr, sourced from vehicle emissions, soil particles, industry, construction dust, biomass burning, and forest fires. Moderate enrichment with Ba, Mn, Ni, Co, and Sn also occurs episodically. Regression analysis highlights solid particles’ role as a major PHE source in rainwater, with the longer antecedent dry periods and the higher acidity level of rain intensifying the accumulation of PHEs. Long-range transport plays a lesser role, with Southern and Northern Europe, Western Siberia, and the central part of European Russia contributing meaningfully.
Noda merah kekuasaan orde baru dalam cerpen “Mei Hwa” karya Gunawan Budi Susanto
Authors: Julianno Ivo Trias
Published: October 2024

Karya sastra adalah representsi realitas yang ada di dalam dan di sekitar pengarang. Hal ini membuktikan bahwa sastra bukanlah sebuah teks yang kosong dan terpisah dari fenomena sosial-budaya yang terjadi di masyarakat. Ia mesti mengandung ‘didikan’ yang berguna bagi para pembaca. Demikianlah makna adagium dulce et utile yang dilontarkan Horace. Meski mengurai banyak perdebatan ilmiah, tetapi dua kata di atas betul-betul mampu untuk menjawab makna kehadiran karya sastra di tengah masyarakat. Penelitian ini bertujuan untuk mendeskripsikan bentuk relasi kuasa yang terdapat dalam cerpen “Mei Hwa” karya Gunawan Budi Susanto. Penelitian ini juga membongkar citra rezim Orde Baru selama Reformasi Mei 1998 menggunakan konsep representasi sastra yang berdasar pada konteks historis di sekitar teks tersebut. Metode yang digunakan selama penelitian terbagi dalam tiga tahap, yakni metode pengumpulan data, metode analisis data, dan metode penyajian hasil analisis data. Data-data dikumpul dengan teknik baca-catat lalu dianalisis menggunakan metode analisis konten. Setelah itu, data-data disajikan menggunakan metode deskriptif kualitatif. Dengan menggunakan teori relasi kekuasaan Michel Foucault, ditemukanlah ‘didikan’ yang dimaksud Horace dalam teks cerpen “Mei Hwa”. Data mengenai relasi kuasa yang terdapat dalam cerpen tersebut meliputi relasi kuasa yang bekerja atas pemikiran, meliputi manipulasi agama, kontrol bahasa, hingga stigmatisasi pada etnis Tionghoa, dan relasi kuasa yang bekerja atas tubuh, meliputi objektifikasi tubuh perempuan Tionghoa yang dijadikan hasrat seksual kaum lelaki hingga kontrol atas tubuh individu berdasarkan pada norma social yang berlaku. Dari keseluruhan hasil penelitian tersebut, ditemukanlah beberapa kesimpulan atas representasi Orde Baru dalam teks cerpen, yakni (1) negara Orde Baru menggunakan media agama, budaya, bahasa, hingga lembaga untuk melegitimasi kepentingan kekuasannya di masyarakat, (2) negara Orde Baru menggunakan kekuatan politik identitas sebagai alat propagandanya dalam melanggengkan kekuasaan di Indonesia, dan (3) militer dan aparatur negara selaku instrumen kekuasaan memiliki peran penting dalam setiap peristiwa kelam yang terjadi di negeri ini.

Authors: Eremeev A.V. , Tyunin N.N.
Published: October 2024

The problem of optimization of the directivity of phased antenna arrays for shortwave radio communication is formulated as a nonconvex quadratic programming problem. Taking into account the specifics of the problem under consideration, a hybrid algorithm based on the method of differential evolution, the method of penalty functions and gradient optimization is proposed. Correction of invalid solutions is carried out by means of their scaling. The penalty coefficient is chosen adaptively during the algorithm execution. A computational experiment was carried out, where the proposed algorithm is compared with the commercial solver BARON, based on repeated application of the local search algorithm and branch and bound method, as well as with the ANTIGONE solver and the gradient algorithm. In addition, the effect of accounting for symmetries of the considered problem is studied. Accordingto the results experiment, we can conclude that the proposed hybrid algorithm is competitive, especially on problems of higher dimension.

“Conservatism” and “Innovations” at the Department of the Medieval History of the Faculty of History of Moscow State University in the 1970s-1990s (analysis of the changes in topics of the graduate theses)
Authors: Anufrieva Anastasia S.
Published: October 2024

The article discusses the changes in topics of the graduate theses, defended at the Department of the Medieval History of the Faculty of History of Moscow State University in the 1970s-1990s. The influence of that Department at Soviet and Post-Soviet Medieval Studies was described from diametrically opposed positions in the context of the so-called "Memoirs War": it was considered either as a leading institution or as an inert “medieval establishment”, suppressing free scientific search of the “unofficial medievalists”. In our opinion, this problem cannot be fully comprehended without referring to the issue of interaction between different generations, an everyday work of the scientific advisors with their students. We investigate a database of diplomas defended at the Department in the period 1970-1990, tracking changes in terminology and analyzing, in what manner was effected the transition from the "conservative" era of the 1970s (which was characterized by an outward adherence to Marxist dogmas) to the thematic and methodological diversity of the 1990s. These changes are characterized not as a sharp fracture and a "revolutionary" establishment of the entirely new approaches, but as a gradual, decades long "shift" of the thematic spectrum: a decrease in the number of topics related to the marxist dogmatism and an increase in the number of works inspired by the other methodological approaches. At the same time there were preserved some elements of the “conservative” tradition, and were developing some “innovative” ideas (at first little by little, and then more and more intensively). An extremely important role in these transformations was played by external factors - socio-political changes, the innovative methodological searches of "unofficial medievalists". However, the mechanisms of "internal self-regulation", which, in our opinion, allowed the university environment to respond to external changes, were also very important.
The Scenes of the Osiris Ritual in the Stela of Abkau (Louvre C 15): Problems of Interpretation
Authors: Mironova Alexandra V.
Published: October 2024

The article deals with the relief scenes of the ancient Egyptian stele Abkau (XI Dyn.), which are usually interpreted in the context of the Osirian cult. On the basis of comparative analysis of drawings and inscriptions of the stele with the Egyptian funerary texts (the Pyramid Texts, the Coffin Texts, the Book of the Dead, the Book of Day and Night) the author reveals the symbolic meaning of stela reliefs in the context of the mythological stories about the birth of the sun god from a lotus flower, the mourning of Osiris, the birth and growth of his son Horus in Buto, the battle of Horus with the enemies of Osiris and his subsequent ascension to the throne, the stay of the solar god and the deceased in the Fields of Offerings and/or the Fields of Reeds, which were considered the dwelling of “blessed” souls. In the context of the solar, Osiris and funerary cults, the Neshmet bark is understood not only as an Osirian boat and a boat of the deceased in the afterlife, but also as an image of a celestial boat, as well as a symbol of the lunar crescent and the horizon line. The study of the composition of stela reliefs reveals that they do not represent the sailing of the Neshmet bark depicted in the middle of the register, but rather its stationary stay in the sanctuary of the temple of Abydos, among the rooms where offerings were made to the various gods mentioned in the line above the middle register.

Published: October 2024

Anthropogenic activities on land will affect the carbon system in coastal waters. This condition will affect the role of coastal waters as a source or sink of carbon. This research will examine the distribution of carbonate systems and estimate CO2 fluxes. Water samples were taken at 30 stations as well as measuring in situ water parameters including pH, temperature, salinity, and pressure. Alkalinity was analysed based on the titration method, chl-a using the fluorometer method, and carbonate system parameters (pCO2(sea) and DIC) calculated using CO2SYS.xlsm. The pCO2(atm) value is calculated based on atmospheric data from satellite data, including the saturation vapour pressure of sea air in the atmosphere, fraction mol of CO2, and sea level pressure. Pearson correlation analysis was used to see the correlation between the measured parameters and CO2 flux. Carbon flux is determined based on the difference between atmospheric and oceanic pCO2. The DIC calculation result was in the range of 1,946.09 µmol/kg - 2,061.65 µmol/kg and the total alkalinity was 2,156.86 µmol/kg - 2,264.71 µmol/kg. Based on this value, Jepara coastal waters have pCO2(sea) of 573,800 micro-atmospheric (µatm) which is higher than pCO2(atm) (i.e., 386,772 µatm). The input of organic/inorganic carbon resulting from anthropogenic processes on land has influenced Jepara coastal waters which act as a source of CO2 into the atmosphere amounting to 103,799 mmol/m2/day. The results of this research can be used as a reference for managing coastal areas to achieve low carbon emissions.
Can Development in the Digital Economy Lead to A Win-Win for ‘Efficiency Promotion’ and ‘Emission Reduction’?
Authors: Chen Weiling , Huang Min , Du Chunjing
Published: October 2024

The contemporary landscape sees the digital economy (DE) as a pivotal driver of economic evolution. Hence, scrutinising its potential to harmonise ‘efficiency promotion’ and ‘emission reduction’ and combat the challenges of climate change in this digital epoch is imperative. This study empirically investigates the influence of DE growth by evaluating its impact on carbon emission scale and energy efficiency. The study employs econometric modelling to delve into the internal mechanisms and diverse characteristics of DE evolution that influence ‘efficiency promotion’ and ‘emission reduction’. Findings underscore a significant capacity within the DE to ameliorate energy efficiency and curtail overall carbon emissions, revealing its dual prowess in fostering ‘efficiency promotion’ and ‘emission reduction’. Robustness tests affirm these outcomes, fortifying the conclusion. Additionally, the effects of DE development on ‘efficiency promotion’ and ‘emission reduction’ are validated in these tests. The study reveals that the ‘efficiency promotion’ and ‘emission reduction’ facets of DE progression exhibit distinctive regional disparities, notably manifesting more pronounced impacts in the eastern regions.
Influence of Diffusion Angle on Sediment Concentration in Front Inflow Forebay of Pumping Station
Authors: Fan Xinjian , Zhang Jiahui , Yao Wei , Dong Chunhai , Wang Lirong , Tian Hao
Published: October 2024

The numerical simulation and field investigation of solid-liquid two-phase flow are carried out in a large-scale forward intake forebay with various diffusion angles at the Jingtaichuan Pumping Irrigation Project in Gansu Province, China. The purpose is to investigate the properties of sediment deposition in the pumping station forebay. The results indicate that the low-sediment concentration area is in the forebay’s centre, whereas the high-sediment is near the two side walls flanks. The sediment concentration increases dramatically from the centre to the sides. Both the high-sediment concentration area and the sediment concentration increase with water depth. The forebay’s narrowing diffusion angle causes the high-concentration area to gradually decrease while the low-concentration area gradually increase. Furthermore, the amount of siltation and sediment deposition efficiency decrease, resulting in a large increase in forebay sediment concentration and sedimentation efficiency. The sediment concentration and water flow velocity reveal a quadratic polynomial relationship. This study can provide a guide and reference for the design and construction of comparable large-scale pumping station forebays.

Published: October 2024

Distribution is one of the problems in the business and industrial world, for example the problem of delivering supplies of raw materials and other goods to several customers, where the delivery must be carried out exactly once by one or more vehicles to each customer with a certain capacity. In its development, this problem was formulated as the Capacitated Vehicle Routing Problem (CVRP). Based on the definition, CVRP is one of the most common variations of the Vehicle Routing Problem (VRP) problem to determine the optimal route with the addition of constraints in the form of homogeneous vehicle capacity. Here, we discussed the CVRP problem of the distribution route for Pak Nurrofiq's gallons of water from the depot to its customers in the Taman Sei Raya Complex, Serdam Asri Complex and Kapuas Mas Complex. The aim of this research is to create a mathematical model for the CVRP problem in the distribution of Pak Nurrofiq's drinking water and solve it using the bee colony algorithm. The bee colony algorithm is a metaheuristic algorithm based on the behavior of honey bees in searching for food sources. The research results show that the case of gallon water distribution was successfully implemented into CVRP and completed using the bee colony algorithm, 4 routes were obtained with a total distance of all routes, namely 9,068 km.

The article presents the results of field research in South-Eastern Kazakhstan in 2022–2023. The authors introduce into scientific discourse information about seven locations of rock carvings with tamgas. Fifteen signs and the petroglyphs that accompany them are being published. The drawings are found on open vertical and horizontal planes of large and small rocky outcrops, on the tops of the southern, southwestern and southeastern slopes of the Kairakkol and Karakungey mountains. The rock carvings were made using two main techniques: picketing and surface carving. Sectors with tamgas are part of large clusters of petroglyphs of different periods, but at the same time they are located separately from other drawings. In one case, a similar sector was discovered on rocky planes located at a distance from placers of rock carvings. Figurative images are represented mainly by geometric symbols and their combinations. Diacritics – dots, lines, arcs and curls. The majority are tamgas, which find indirect analogies in the signs of the nomads of the Northern Black Sea region, Ustyurt, Southern Kazakhstan, Southern Siberia and Mongolia at the turn of eras. Among the petroglyphs that accompany the signs, there are images of snake-like and dragon-like figures, silhouette and outline figures of animals, some of which are made in an openwork manner. A new series of tamgas, identified in Eastern Semirechye, shows broad ethnocultural connections, the originality of the region’s population in the Hunno-Sarmatian period and the migration routes of nomads along the Dzungarian Alatau mountain system.

Authors: Almeida Alice Jadneiza Guilherme de Albuquerque , Lira Bruna Silveira , Gomes Guilherme José Correia , Jucá José Fernando Thomé , Mariano Maria Odete Holanda , Motta Sobrinho Maurício Alves da
Published: October 2024

Objective: The aim of this study is to investigate the analysis of the geotechnical behavior of pure soil and mixtures of soil with composted product for use in landfill cover layers.
 
Method: The methodology adopted for this research includes laboratory tests for the physical characterization and determination of the properties of the materials used for the oxidative cover layer. To prepare the oxidative layer, it was necessary to mix organic compost with clay soil. The soil was collected from a deposit located near the Muribeca Landfill in Pernambuco.
 
Results and Discussion: The analyses performed allowed a positive assessment of the geotechnical capacity that the mixtures can provide under the condition of landfill cover layers. The mixtures had a small increase in the proportion of coarser granulometry, reducing the plasticity of the material with the addition of the compost, possibly increasing the permeability of the layer. Also, the addition of compost did not cause a great loss in the geotechnical load-bearing capacity of the material.
 
Research Implications: The material studied has shown potential suitability for use in oxidative covering layers for landfills, proving to be a viable alternative for implementation in smaller municipalities with less purchasing power, effectively reducing the need for the use of clayey materials, without compromising the safety of operation and subsequent use of the landfill site.
 
Originality/Value: One of the difficulties encountered by municipalities in the use of landfills is the search for materials suitable for the solution, especially in municipalities with less purchasing power or located in arid regions, where the use of conventional layers presents problems, with drying out and opening of fissures. The relevance and value of this research are evidenced by the viability of the association of clayey soils with organic compost for the preparation of oxidative covering layers, reducing the pollutant load of organic waste.

The supremacy of the Constitution in the exercise of power and state governance is the essence of Xi Jinping's ideas on the rule of law. Chinese conceptions of thesupremacy of the Constitution in state governance and the exercise of power are fundamentally different from so-called Western "constitutionalism". The essence of adopting theConstitution as a basic guide to action is to better transform the constitutional institutioninto an effective way of governing the country. Adherence to the comprehensive leadershipof the CPC is one of the basic requirements of the Chinese Constitution and constitutes theessence of the supremacy of the Constitution in governing the state and exercising power. "The people" is the goal of the supremacy of the Constitution in governing the state andexercising power. Following the set of socialist institutions with Chinese characteristicsinvolves maintaining, strengthening and improving the essential, basic and important institutions defined by the Constitution. To this end, it is necessary to adhere to the organicunity of the Party leadership, the rule of law in governing the state and the role of the peopleas full masters in the country, so as to realize the fundamental right of the people to governthe state, and to enhance the vitality of the Party and the state, mobilize the enthusiasm ofthe people, expand socialist democracy and develop socialist political civilization. The supremacy of the Constitution in the governance of the state and the exercise of power playsa leading role in the comprehensive rule of law in the governance of the state and shouldbe based on its deep implementation. The rule of law in the governance of the state and theexercise of power and the rule of rules in party governance are not pseudoscientific gamesof terms, but the scientific expression of the rich practice and dialectical relationship ofcomprehensive governance of the state in accordance with the law.
Intraventricular pilocytic astrocytoma: A case report
Authors: Algarni Almohannad S , Alasmari Saud S , Alqahtani Abdulaziz S , Alshammari Turki D , Alkhairi Abdu M
Published: October 2024

Background: Pilocytic astrocytomas (PA) are low-grade, benign gliomas classified as WHO grade I, representing 6% of all gliomas and commonly found in children. Intraventricular pilocytic astrocytomas (IVPA) are rare, accounting for only 4% of PA cases.

Case Presentation: We report a 42-year-old Saudi woman with recurrent positional headaches but no neurological deficits. MRI showed a 1.2-cm non-enhancing lesion near the foramen of Monro, initially thought to be a colloid cyst. The lesion was excised via an interhemispheric transcallosal approach. Histopathology confirmed PA with biphasic tissue, glomeruloid vessels, and strong GFAP positivity, classified as WHO grade I. No further chemotherapy or radiotherapy was required.

Postoperative Outcome: Post-surgery, the patient had transient short-term memory issues, partially resolving within six months, and her headaches ceased. Initial imaging showed pneumocephalus, which resolved after one month.

Discussion: IVPA typically remain asymptomatic until they cause hydrocephalus by obstructing cerebrospinal fluid pathways. Radiologically, they appear as well-defined lesions with mixed cystic and solid components. Complete surgical resection is crucial to minimize recurrence.

Conclusion: IVPA, though rare in adults, should be considered in the differential diagnosis of intraventricular lesions. This case highlights the significance of accurate diagnosis and surgical management for this uncommon tumor.

This study examines impacts of climate change and natural disasters on livelihoods in Dien Bien province, located in Northern Mountainous Region of Vietnam. Based on meteorological data, household surveys, interviews, and focused group discussions conducted across four communes, the research finds that Dien Bien is experiencing more frequent and intense extreme weather events, including heavy rainfall, landslides, and droughts. These changes are severely impacting agriculture-dependent ethnic minority communities, with over 60% of households reporting arable land and crop productivity losses of 40-65% in 2022 alone. Income losses are the most pronounced in remote areas, where 62% of households lost over half of their annual income. While social welfare and climate-smart agriculture programs exist, the coverage and adoption rates vary widely across communes. The findings highlight the disproportionate impacts on marginalized populations and the need for tailored, culturally-sensitive adaptation strategies. The study recommends promoting multipurpose tree planting, establishing community-based nurseries, diversifying livelihoods through small-scale family activities, and expanding inclusive financial mechanisms to enhance resilience. Findings from this study provide new insights into the complex vulnerabilities of ethnic minority communities in mountainous regions and offers targeted interventions to safeguard their livelihoods under accelerating climate change.

Female Sexualities under a Patriarchal Microscope: An Interrogation of Buchi Emecheta’s Double Yoke
Authors: Masha Lethabo , Mogoboya Mphoto Johannes
Published: October 2024

This qualitative study amplifies the endemic policing of female bodies by patriarchal ideology whereby the sexual lives of African women are often suppressed whereas men receive little to no scrutiny. The paper thematically analyses Emecheta’s purposively sampled novel Double Yoke (1983) to interrogate the aforementioned problem which is still relevant to the present collective African milieu. Stiwanism is employed as a theoretical lens particularly because of its advocacy for bodily autonomy and selfhood as part of the important freedoms that African women should be afforded in the realisation of social transformation. The main finding was that throughout African history, this prejudiced supervision has existed and consequences included psychological harm as well as ostracisation. Therefore, this study recommends that sexual rights bills be supplemented by sociopolitical will and that African societies be conscientised. To ensure the overall wellbeing of all members in society, biased beliefs about sexuality should be abolished.

The study explored the grade 9 learners’ perceptions of the influence of peer relationships on their mathematics performance in Tshwane municipality secondary schools, South Africa. The study engaged a mixed method approach and applied a descriptive survey design. The sample consisted of 400 learners (280 females and 120 males). A self-fashioned questionnaire was used for data collection, as well as a few open ended questions. The learners’ termly result in mathematics was also used to ascertain their level of achievement. Quantitative data were analysed using the Pearson product moment correlation, while qualitative data were analysed in a narrative form. One null hypothesis was tested for the study and it was rejected. The study disclosed that grade 9 learners’ perceptions of peer relationships was not a statistically significant factor influencing their mathematics performance. The study concluded that peer relationships were poorly appraised, hence could not have influenced grade 9 learners’ mathematics performance. The study recommends that teachers and stakeholders in schools should consider the advocacy of positive peer relationships among learners to help foster acceptability among learners. Furthermore, advocacy for cooperative and interactive learning is recommended to enable learners to learn from each other effectively; this will foster peer mentoring.
The Plight of Employment Policies that Exclude Customary Practices in the Workplace
Authors: Cwele Samukelisiwe , Petse Isiphile
Published: October 2024

South Africa is called a “rainbow nation”, and with its 11 official languages, the country is a melting pot of diverse cultures, traditions, and beliefs. This diversity is not without challenges. This brings interesting and complex questions from an employment perspective; therefore, striking a balance between the employer’s rights versus the employee’s traditional practices has become a significant challenge. The article analyses these challenges that arise as a result of the failure of section 8(3) of the Constitution to give a direct mandate to develop customary law to put into effect or limit a right that is found in the Bill of Rights and in this instance the right to fair labour practices in terms of section 23. The article will also analyse the cases dealing with employees who wanted to enforce their rights conferred to them by the Constitution to practice their culture but were excluded and discriminated against on some of the grounds listed in section 9(3) of the Constitution. The article will conclude by recommending that labour laws and the Constitution should be reviewed to cater for native persons, in particular, the recognition of customary laws and practices at the workplace.
