Published: December 2024

Sex education for children is an effort so that children can learn about gender and also how to protect it, both in terms of crime, cleanliness and safety. This research was conducted with the aim of providing mothers with sex education starting at an early age. Researchers carry out research at the school stage at the age of 7-12 years, because at this stage children will always want to know about something and are also able to receive information correctly and apply it. Regarding this, health education is given to mothers because as a mother she must have good knowledge to teach sex education to her child, with the aim that the child can learn sex education correctly and it will not have a negative impact on him. The writing of this research uses a quantitative research method with a descriptive analysis method which aims to look at phenomena that occur in a certain population using a cross sectional approach where data relating to variables will be collected at the same time. Data collection was carried out directly from respondents using questionnaire sheets. As a result, it was concluded that the effectiveness of health education on mothers' level of knowledge in providing sex education to school children aged 7-12 years showed that 30 mothers (90.9%) were in the high category and 3 mothers (9.1%) were in the medium category.

Authors: Irawan Muhammad Zudhy , Putri Nurjannah Haryanti
Published: December 2024

Bercampurnya berbagai jenis kendaraan di ruas jalan yang didominasi oleh sepeda motor menjadikan analisis karakteristik lalu lintas dengan metode mikroskopik menjadi lebih sesuai karena metode ini memperlakukan setiap jenis kendaraan sebagai individu itu sendiri. Namun, perilaku pengemudi di Indonesia yang khas mengharuskan proses penyesuaian (kalibrasi) yang lebih detail. Penelitian ini bertujuan untuk membuat sebuah standar proses kalibrasi di simpang bersinyal dengan perangkat lunak VISSIM sedemikian sehingga kondisi nyata di lapangan dapat secara tepat direpresentasikan di model simulasi. Simpang Tugu di Kota Yogyakarta dipilih sebagai sebuah studi kasus. Proses kalibrasi dilakukan secara trial and error dengan mempertimbangkan perilaku pengemudi yang agresif sehingga menyerupai kondisi di Indonesia. Terdapat dua variabel yang diamati kesesuaiannya pada penelitian ini, yaitu jumlah volume lalu lintas yang dibangkitkan, dan panjang antrian di masing-masing lengan simpang untuk setiap siklusnya. Hasil penelitian menunjukkan bahwa parameter-parameter yang perlu dikalibrasi di perangkat lunak VISSIM adalah pemilihan lajur jalan yang digunakan pada kondisi arus bebas (desired position at free flow), perilaku pengemudi yang dapat menyiap kendaraan lain (overtaking), sudut belok kendaraan saat keluar dari pendekat simpang (turning movement), dan jarak antara kendaraan baik pada saat berhenti maupun pada saat memasuki pendekat simpang (distance standing, distance driving, average standstill distance, additive part of safety distance, dan multiplicative part of safety distance).

The subject of the study is the organization of documenting the population registration of the Kangalas Tungus Clans Administration Department for 1768-1917. The purpose of the study is to identify a set of archival documents on the registration of the Kangalas Tungus population preserved during the period 1768-1917, to clarify the type, time and specifics of their creation and to reveal their information capabilities. The geographical scope of the study is limited and corresponds to the area of residence of the clans subordinate to the department of the Kangalas Tungus clans. The methodological basis of the study is the principles of historicism, scientific and objectivity. A systematic approach made it possible to consider the entire set of documents of generic departments as a whole. The method of source analysis made it possible to assess the information value and practical significance of the identified documents. As a result of our work, we have identified a set of documents on the registration of the population of the Kangalas Tungus clans, identified the specifics of their formation and practical use in the activities of the Council, prepared an electronic database containing information about the generic composition and places of nomads. The scientific novelty of the study consists in conducting a source analysis of the identified set of documents of the Kangalas Tungus clans, their information capabilities in recreating the demographic and socio-cultural appearance of the Tungus clans. Based on the results of the work, it was concluded that further research is necessary due to the presence of a large number of unpublished documents. The research materials can be used in the process of teaching historical disciplines, developing textbooks, conducting separate and generalizing studies on the history of the indigenous peoples of the North.
Lexical ways of designating the Internet in modern Russian: semantics, pragmatics, spelling
Authors: Dedova Olga Viktorovna , Podolskaya Valeriya Viktorovna
Published: December 2024

The article focuses on the words that designate the Internet and its segments and discusses such problems as the process of assimilation of lexeme "интернет" in contemporary Russian language and its spelling variants, the reasons and mechanisms of appearance of its synonyms. Formal and cognitive adaptation of the anglicisms "internet", "web", "net" and stylistic peculiarities of word-formative and semantic derivatives that appeared on the base of Russian language are also discussed. Particular attention is paid to the tendency for some English-language stems to become affixoids in contemporary Russian. Modern explanatory dictionaries and corpus data were used as sources of linguistic information about the functioning of investigated lexemes ([https://ruscorpora.ru/], [http://www.webcorpora.ru]), data obtained by search by keywords was also analyzed. Descriptive method was used in the research. Identified designations of the Internet, as well as its segments, are analyzed in terms of their origin and semantics. Their stylistic features are also explained. The research’s scientific novelty lies in identifying for the first time a variety of lexemes designating the Internet and its segments. The article considers the process of adaptation of lexical units denoting the concept of "Internet", as well as the peculiarities of their functioning in contemporary Russian language. The reasons for the emergence of synonymic designations of the word "Internet" and their peculiarities are analysed. A number of studied nominations ("глубокий", "черный" vs. "поверхностный", "белый интернет") are not listed in modern explanatory dictionaries. The conducted analysis allowed us to draw the following conclusion: synonyms of the lexeme "интернет" that appeared in Russian language, on the one hand reflect the denotative significance of the realia called "Internet", its role in modern society, and on the other hand the synonyms demonstrated significant word-formation and cognitive potential of contemporary Russian language.
Ideological models of modern Russian society: theoretical and methodological construct of the study
Authors: Konstantinov Mikhail Sergeevich
Published: December 2024

The article presents the main aspects of the author's theoretical and methodological construct for studying the worldview models of modern Russian society. The object of the study was the processes of worldview formation in the consciousness of generations of modern Russia, the subject was the theoretical and methodological basis for studying the worldview models of Russians in generational and regional dimensions. The history of the concept of worldview in philosophy and social sciences is considered in detail, the features of its conceptualization in modern dictionaries and reference books are revealed, and the heuristic potential of using the concept of worldview proposed by K. Jaspers as a complex process of internalization of the socio-cultural worldview base with subsequent objectification of subjective experience is shown. It is the insurmountable gap between the objective and the subjective in Jasper's concept of worldview that allows us to record generational differences based on the principle of "meta-contrast". The theoretical and methodological basis of the study was a critical conceptual analysis, the concept of worldview by K. Jaspers, as well as the theory of self-categorization by J. Turner with its key concept of "meta-contrast". All this theoretical and methodological work took place in the context of a model approach to worldview. As a result of the study, it was established that more than two hundred years of development of the concept of worldview led to its extreme vagueness and comprehensiveness, which could not but negatively affect its heuristic potential. To correct this situation, a model approach to worldview was proposed, which made it possible to operationalize this concept for subsequent quantitative research of mass consciousness in order to identify connections between the worldview base of Russians and its ideological derivatives.
Airfoil Separation Constraint Formulation for Aerodynamic Shape Optimization
Authors: Abdul-Kaiyoom Mohamed Arshath Saja , Yildirim Anil , Gray Alasdair C. , Martins Joaquim R. R. A.
Published: December 2024

Airfoil design using numerical optimization has addressed the problem of minimizing drag for a given lift constraint for one or more flight conditions. However, designers often want to avoid separation at off-design conditions regardless of the drag. This paper develops a separation constraint formulation for airfoil shape optimization. We perform multipoint optimizations and demonstrate how a separation constraint yields practical airfoil shapes. We compare results from single-point optimizations with and without a leading-edge radius constraint, which is a simple approach used as a surrogate to avoid separation, to an optimization where separation is constrained at a low-speed high-lift off-design point. Constraining the leading-edge edge radius improves the high-lift performance of the airfoil but not as much as constraining separation at the off-design point. We also compare the results of separation-constrained optimizations with optimizations where the drag at an off-design point is included in the objective. The latter formulation also produces optimal designs that are separation-free at the off-design points. However, the separation-constrained formulation produces airfoils with better cruise performance. Finally, we demonstrate the separation constraint efficacy at the off-design point with multiple cruise points. The results help guide parameterization and constraint formulation for airfoil design optimization problems.
Hybrid Spatial–Spectral Autoencoder Models for Lossy Satellite Image Compression
Authors: Badr Mohamed Ahmed , Elrewainy Ahmed Fathy , Elshafey Mohamed Abdelmoneim Taha
Published: December 2024

The challenge of handling vast amounts of high-resolution satellite imagery is driven by onboard memory and bandwidth limitations. As spatial and spectral resolutions increase, image compression, particularly deep-learning-based methods, is essential to overcome these limitations. This paper presents hybrid autoencoder models that combine convolutional neural networks, long short-term memory networks, and attention mechanisms for spatial and spectral feature extraction. The proposed architectures, including sparse and variational autoencoder counterparts, form a comprehensive image compression framework with quantization, and various entropy coders are applied to the EuroSat dataset (RGB and multispectral). The experimental results show the models’ superiority over the JPEG family and recent state-of-the-art methods, achieving up to 3.3, 1.4, and 0.6% improvements in the peak signal-to-noise ratio, structural similarity index, and multiscale structural similarity index, respectively. Moreover, performance analysis in terms of computational complexity, processing time, and memory usage highlights the efficiency of the proposed models. A case study conducted on a real scene from the Sentinel-2 satellite further validates the compatibility of the proposed models with modern artificial intelligence chipsets.

The authors have conducted laboratory experiments to study the ability of the Barents Sea brown alga Fucus vesiculosus L. to adsorb technogenic radionuclides from seawater of various salinity (8, 18 and 35 psu). They have obtained new data on the role of macroalgae communities in the geodynamics of radionuclides in the coastal zone of the seas. Fucuses are able to adsorb 40—80% of the radionuclide activity from water. The maximum intensity of adsorption is observed during the first day of exposure. The alga most effectively absorbs 152Eu, 241Am, 65Zn, 54Mn from water. The possibility of using the alga as a sorbent in biobarriers in incidents with emergency discharges of radioactivity into the sea is shown.

Disk Evolution of Classical Be Stars with Misaligned Binary Companions
Authors: Suffak Mark W. , Jones Carol E. , Carciofi Alex C.
Published: December 2024

Classical Be stars are rapidly rotating B type stars that are surrounded by a gaseous circumstellar decretion disk. Like many massive stars, Be stars are frequently found to exist in binary systems, with a wide array of orbital configurations. Recently, we have computed three- dimensional (3D) smoothed particle hydrodynamics (SPH) models of Be stars with equal-mass binary companions whose orbit is misaligned to the initial plane of the disk and found that the misaligned companion can cause the disk to undergo phenomena of Kozai–Lidov oscillations, and disk-tearing, in addition to the expected tilting and warping of the disk. We now show that these phenomena are not unique to equal-mass systems, but that there is a range of mass ratios for which disk-tearing and Kozai–Lidov oscillations can occur. We also find that an increase in viscosity can suppress these phenomena. Next, we combine our SPH models with the 3D nonlocal thermodynamic equilibrium Monte Carlo radiative transfer code HDUST to produce synthetic spectra of these systems. We show how both phenomena can change the Hα emission line profile, and how disk-tearing creates a detectable polarization signature. We also present a comparison of the observable trends in our disk-tearing model, and how these mimic the changes observed in Pleione (28 Tau). Overall our results demonstrate how phenomena from a misaligned binary companion can cause variations in observables across the whole disk, and that these phenomena need to be considered when analyzing the time evolution of Be star spectra.
The Polstar UV Spectropolarimetry Mission
Authors: Ignace Richard , Scowen Paul
Published: December 2024

The Polstar small explorer concept is for an ultraviolet (UV) spectropolarimetry space telescope mission with a focus on massive star astrophysics. The instrument waveband will be from 115 nm to 286 nm for spectroscopy, and from 122 nm to 286 nm for polarimetry. All four Stokes parameters, I, Q, U, and V , will be measured at a resolving power of R=20,000 (15 km s−1 velocity resolution). The telescope aperture will be 40 cm with an effective area of about 22 cm2 at a reference wavelength of 150 nm. The thrust of the science goals will be to determine the astrophysics of angular momentum exchange and transport, and consequences for massive star properties and evolution. This includes the effects of rapid to critical rotation for individual stars (magnetic and non-magnetic), and the effects of mass transfer for massive binaries, including identification of stripped core stars. If selected by the NASA/SMEX program, Polstar would launch around 2031 and observe ∼300 stars to achieve science goals. The mission will include a Guest Observer program to advance discovery in other areas of astrophysics.
Post-supernova Binary Interactions
Authors: Hirai Ryosuke
Published: December 2024

Binary evolution plays a key role in determining the properties of supernova progenitors, while supernova explosions can also significantly impact the evolution of the binary. In this paper I discuss several forms of binary interactions that happen immediately after supernova explosions and their observational consequences. I first discuss energy deposition into the companion envelope through ejecta–companion interaction, that can cause the star to temporarily inflate and become overluminous. I show that we can use this to constrain pre-supernova binary properties if we observe the inflated state of these companions and their later deflation. I then discuss direct collisions between new-born neutron stars and companion stars. Depending on the kick velocity and impact parameter, the neutron star can sometimes penetrate the companion envelope and capture part of the material, causing multiple bumps in the light curve through accretion feedback. I then briefly discuss how to combine these two studies to explain the undulations in the recently discovered SN2022jli.
Modeling Stellar Wind Spectra from Rapidly Rotating Stars
Authors: Hamann Wolf-Rainer , Schulz Ludwig , Todt Helge
Published: December 2024

In post-interaction massive binaries (PIMBs) one often finds rapidly rotating objects, e.g., after one component has accreted mass and angular momentum, or after two components merged. Being hot and luminous, such objects drive stellar winds. Models for stellar atmospheres and winds usually adopt spherical symmetry. However, rapid rotation would break this symmetry.We have developed a version of the Potsdam Wolf–Rayet (PoWR) model atmosphere code which allows to combine two different atmosphere models, e.g., one for the rapid wind over the polar regions, and a second one for the slower wind over the gravity-darkened equatorial zone.For two examples we will demonstrate that such 1.5-D spectral simulations can explain observed wind-line profiles which otherwise cannot be reproduced.
La simplicité peut être trompeuse : un nouveau regard sur les variations périodiques de WR 6
Authors: Chené André-Nicolas , Lenoir-Craig Guillaume , St-Louis Nicole , Moffat Anthony F. J.
Published: December 2024

WR 6 is variable with a period around 3.7 days, but the period and the shape of the variations seem to be different in every dataset. Looking at historic light curves, we suggest that variations are mostly absorption features. Examining the BRITE satellite light curve, every feature seems to have a slightly different period from one another. We propose that the variations come from Corotating Interaction Regions in WR 6’s wind and that the star shows differential rotation.

We revised the parameters of the High-mass X-ray Binary IGR J17544-2619 using the well-measured distance to the system from the Gaia survey. We modeled the spectrum of the optical component using the PoWR model grids, and CMFGEN code and determined its physical parameters: Teff = 32000 K, log g = 3.6, L∗ = 1.8×105 L⊙, mopt = 27.5 M⊙. The measured parameters made it possible to determine the optical component's position on the Hertzsprung–Russell diagram as a star that has left the Main Sequence.

Description of the subject. In Mali, cotton (Gossypium hirsutum L.) plays an essential role in economic and social activities in terms of income generation, rural organization and modernization of production systems. Cotton topping is a cultivation technique that reduces the growth in size of the cotton plant while favoring the production process. Objectives. The aim of this study was to evaluate the effect of topping combined with new sowing density on seed-cotton yield. Method. The study was conducted in Mali over two years (2020 and 2021) at the Finkolo research station in the Sudanian zone and one year (2022) in farmers’ fields. The experiment included two cotton varieties (NTAMS334 and BRS293) and two sowing densities, with or without topping cotton plants. The recommended sowing density of 80 cm x 30 cm with two plants per seed hole was compared with a new sowing density of 80 cm x 20 cm with one plant per seed hole. The main advantage of the new sowing density was the acceleration of the cotton plant's growth in height, thanks to the strong competition for light before topping. Results. The results showed that topping significantly reduced the average number of fruit-bearing branches per cotton plant (14 for the non-topped modalities and 10 for the topped modalities). The number of fruiting positions occupied per plant, boll load per plant, and seed-cotton yield increased with topping. The highest seed-cotton yields at the research station (2,238 kg·ha-1) and in farmers’ fields (2,391 kg·ha-1) were obtained with the new sowing density combined with topping. Conclusions. The results of this study can be used as a modifier of canopy and sowing density under cotton overgrowth conditions.

Предложен алгоритм отображения полярного сияния в геоинформационном продукте ArcGis, а также приведен алгоритм поиска центра полярных сияний или же поиск геомагнитного полюса земли, основанный на языке программирования python. Предложенный алгоритм предоставляет полезный инструмент для понимания, в каких местах будет видно полярное сияние и с какой интенсивностью. А также благодаря поиску центра полярного сияния возможно найти центр геомагнитного полюса, который часто меняет свое местоположение, что, в свою очередь, дает возможность лучше определить местоположение полярного сияния, а также прогнозировать как само полярное сияние, так и его интенсивность, что позволяет подготовиться к техногенным рискам от аврорального овала. Для получения данных аврорального овала был создан скрипт на языке программирования php, который сохраняет данные со станций на облачное хранилище, такое как Яндекс.Диск.

The paper proposes an algorithm for displaying the aurora borealis in the geoinformation product of ArcGIS and gives an algorithm for searching for the center of the aurora borealis or searching for the geomagnetic pole of the earth. This algorithm is based on the python programming language. The proposed algorithm provides us with a useful tool for understanding of that, in which places and with which intensity the aurora borealis will be visible. Also thanks to the search for the center of the aurora borealis, it is possible to find the center of the geomagnetic pole, which often changes its location, which in turn gives us the opportunity to better determine the location of the aurora borealis, as well as to predict both the aurora itself and its intensity, it allows us to prepare for man-made risks associated with the auroral oval. To get the auroral oval data, a script was created in the php programming language that keeps data from stations to a cloud storage such as Yandex.Disk.

Рассмотрены естественные природные и технологических факторы, а также научно-технические проблемы, связанные с глубиной разработки в сложных горно-геологических условиях. Раскрытие содержания одного из распространенных понятий - «глубина разработки» - позволило сформулировать методологический подход для оценки изменения горнотехнических процессов при освоении месторождений полезных ископаемых. Дано расчетное математическое определение технологическому понятию «глубина разработки» различных месторождений. Раскрытие содержания этого одного из самых распространенных параметров месторождений полезных ископаемых в рамках анализа современного уровня научно-технического состояния основных процессов горного производства позволило обосновать применение автоматизированной системы корректировки параметров выработок по мере увеличения из глубины. Показано существенное изменение условий горнотехнических процессов при разработке месторождений полезных ископаемых. Отмечено влияние таких факторов, как увеличивающееся горное давление и образование техногенных зон, примыкающих к участкам горных работ. Данный подход связывает проблему влияния глубины разработки с экономической оценкой результатов коррекции процессов горного производства.

The paper considers natural and technological factors, as well as scientific and technical problems related to the depth of development in difficult mining and geological conditions. The disclosure of the content of one of the common concepts - "depth of development" - allowed us to formulate a methodological approach for assessing changes in mining processes during the development of mineral deposits. We give a calculated mathematical definition of the technological concept of "depth of development" of various fields. The disclosure of the content of this one of the most common parameters of mineral deposits in the framework of the analysis of the current level of scientific and technical state of the main mining processes made it possible to justify the use of an automated system for adjusting the parameters of workings as they increase from depth. A significant change in the conditions of mining processes during the development of mineral deposits is shown. The influence of such factors as increasing rock pressure and the formation of man-made zones adjacent to mining areas is noted. This approach connects the problem of the influence of the depth of development with the economic assessment of the results of the correction of mining processes. The relevance of the approach is to trace on some aspects of its application with the depth of development.

При взрыве ВВ в скальных породах вблизи заряда формируется область измельчения материала среды. Объем данной области значительно меньше всего объема разрушаемого взрывом материала. Однако в этой области происходит значительная диссипация энергии взрыва вследствие измельчения и (или) пластического деформирования среды. Данный процесс обусловливает уменьшение количества движения, полученного средой вне зоны измельчения при взрыве заряда ВВ. Приведена оценка величины удельного импульса, передаваемого скальной горной породе при взрыве цилиндрического заряда с учетом потерь в зоне измельчения. Полученные результаты позволяют осуществлять сравнение дробящих способностей различных взрывчатых веществ, что придает им практическую ценность.

When explosives detonate in rocks, an area of grinding of the medium material occurs near the charge. The volume of this area is much smaller than the total volume of the material destroyed by the explosion. However, in this area there is a significant dissipation of the explosion energy due to grinding and (or) plastic deformation of the medium. This process causes a decrease in the amount of movement received by the medium outside the grinding zone during the explosion of the explosive charge. The paper gives an estimate of the magnitude of the specific impulse transmitted to the rock during the explosion of a cylindrical charge, taking into account losses in the grinding zone. The obtained results make it possible to compare the crushing abilities of various explosives, which gives them practical value.

В направлении совершенствования методов учета переходных процессов в буровзрывных работах установлена зависимость скорости сейсмических колебаний от приведенного расстояния для условий Карагайского карьера (ПАО «Комбинат Магнезит»). В результате анализа многолетних данных фактических измерений сейсмики взрывов, полученных лабораторией разрушения горных пород ИГД УрО РАН на различных месторождениях Урала, Сибири и ближнего зарубежья установлены и приводятся средние отклонения фактических колебаний от расчетных значений при различных коэффициентах грунтовых условий. Разработана и представлена номограмма, которая позволяет при известной скорости продольной волны в массиве и предполагаемом коэффициенте структурного ослабления определить допустимую скорость сейсмических колебаний массива горных пород в естественном залегании. Обозначены подходы для перехода к технологии отработки сложноструктурных пластовых месторождений, обеспечивающие требуемую кусковатость.

In the direction of improving the methods of accounting for transients in drilling and blasting, the dependence of the speed of seismic vibrations on the reduced distance for the conditions of the Karagai quarry («Magnezit Combine») has been established. As a result of the analysis of long-term data of actual measurements of seismic explosions obtained by the rock destruction laboratory of the Institute of Mining at various deposits of the Urals, Siberia and neighboring countries, the average deviations of actual fluctuations from the calculated values for various coefficients of ground conditions are established and given in this paper. A nomogram has been developed and presented, which allows, at a known longitudinal wave velocity in the array and the assumed structural attenuation coefficient, to determine the permissible rate of seismic vibrations of the rock mass in the natural occurrence. The approaches for the transition to the technology of mining complex-structured reservoir deposits, providing the required lumpiness, are indicated. The results of the study of the detonation characteristics of the industrial emulsion explosives Poremit 1A and NPGM and the effect on them of the means of initiation of various manufacturers are presented. The main factors affecting the wear resistance of the supports of the ball bits are presented. The directions of development of further research of the laboratory of rock destruction according to the State task 2022 - 2024 are proposed.
