Application of Landsat-8 Satellite Data to Predict Ore Mineralization for the Northern Territories on the Example of the Central Part of the Maloural Zone (The Polar Urals)

A new approach was developed during this study. It is focused on identifying probabilistic zones of increased fracturing (zones with a high density of lineaments), considered as a predictive feature for the localization of ore mineralization in the central part of the Malouralskaya zone (part the Polar Urals). This area is promising for the identification of ore occurrences of the polymetallic type (Fe, Cu, Cu–Zn, Au–Cu). Density maps of lineaments were built basis on the developed approach. In addition, predictive schemes for the distribution of highly permeable rock zones and promising areas for the polymetallic mineralization was identified, taking into account geological information, the distribution of mineral resources, and the outcome of remote sensing data processing. The last is based on identifying structures by manual and automatic approaches and their integration using the theory of fuzzy logic. Morphostructure maps were obtained from Landsat-8 data. These maps show that the known polymetallic ore occurrences in the region (Cu, Cu–Zn, Cu–Pb–Au, Fe–Ti–V, Cu–Pt) are located along the perimeter of a large morphostructure of the 1st order, or near extended tectonic structures for up to 20 km with mainly NE and less often NW trends. We identified six prospective zones by comparing remote sensing results with the geological map of the studied territory and known ore occurrences. The highlighted areas showed spatial consistency with several known polymetallic ore occurrences.
Professional Development for Student Teachers Focusing on Inclusive Education and Fostering Self-Determination

Inclusive education is a pedagogical philosophy that emphasizes embracing and accommodating the diversity of learners within a single educational environment. It is about creating an atmosphere of acceptance, where every student feels valued and has access to the same educational opportunities. Professional development for student teachers, particularly in the realm of inclusive education, plays a pivotal role in shaping their ability to create inclusive and empowering learning environments. The concept of self-determination, which involves fostering Self-regulation, Self-realization, Autonomy and Psychological empowerment in students, is crucial in the context of inclusive education. The depth of understanding and application of self-determination skills may vary between student teachers with bachelors’ and masters’ degrees. In the study, the researchers utilized a simple random sampling technique. This method is considered unbiased and ensures that the selected sample is representative of the entire population. The researchers specifically examined the self-determination of student teacher in relation to their highest qualification. This means they wanted to understand how self-determination varied among student teacher based on whether they held a bachelors’ degree or masters’ degree. The findings of the study revealed that student teacher with a bachelor’s degree demonstrated higher levels of self-determination compared to those with other qualifications. This suggests that there may be a correlation between the level of education and the degree of self-determination among student teacher. The study emphasized the importance of investigating the impact of professional development on self-determination, especially at different education levels. This exploration is crucial for understanding how teacher training programs can be improved to enhance the quality of inclusive education practices in schools. The study highlighted the potential impact of professional development on self-determination, indicating that higher education levels, such as obtaining a bachelor’s degree, might contribute to increased levels of self-determination among student teacher.
Entropiya kogerentnykh sostoyaniy opticheskikh poley

We consider statistical mixtures of two and three arbitrary coherent states that are the states of a data carrier in an optical communication channel. The eigenvalues and eigenvectors of the corresponding density operators are obtained in analytic form. For this purpose, an original parameterization of triangles on the complex phase plane is introduced. Analytic expressions are obtained for the von Neumann entropy of mixtures of two and three arbitrary coherent states, and its maximal value for a given average number of photons is calculated. It is found that the use of three coherent states for a given average number of photons ensures a larger capacity of an optical communication channel as compared to two states.
Ob integrale po vremeni ot elektromagnitnogo polya

The integral over time of an electric or magnetic field in infinite limits (Bessonov integral) is considered; it is shown that it is equal to zero for any configuration of the free electromagnetic field with zero total energy. The connection between zero Bessonov integral and the impossibility of emission or absorption of a photon by a free charged particle is investigated. Exact expressions for the radiation field as well as its Fourier transform are obtained for an electric charge with an abrupt change in the velocity; it is shown that the Bessonov integral of such a radiation field equals zero as follows from the general statement. In conclusion it is shown that a nonzero Bessonov integral of the radiation field produced by an electric charge moving with acceleration, which has been reported in a number of publications, appears because of the incorrect decomposition of the total field of the accelerated charge into the radiative and nonradiative components.

Bismuthite from Au–Bi and Post-Gold Sb Mineralizations within the Darasun Deposit, Eastern Transbaikalya

The Late Jurassic late-orogenic volcanogenic-plutonogenic Darasun deposit of the gold-sulphide-quartz formation holds Au–Bi and post-gold Sb mineralizations. Carbonate-quartz-sulfide veins in Western part of the deposit are surrounded by listvenite rims. Their golden ores were formed under conditions of low activity of S2, they contain pyrrhotine, arsenopyrite, chalcopyrite, pyrite, bismuthate I (Bi1.89–1.98Sb0.11–0.02)2S3, galenobismuthite, nests of bismuth and ikunolite Bi4S3. There is observed exsolution of ikunolite mainly into the native bismuth (Bi0.98–1Sb0.02–0) and bismuthite-II; the composition of bismuthite-II in center of aggregates with the bismuth is (Bi1.96–1.97Sb0.04–0.03)2S3, whereas the composition on their periphery is an more antimonian one is (Bi1.91–1.92Sb0.09–0.08)2S3. While the high fineness gold (970–935 ‰) arose there by the action of gold-bearing hydrothermal solutions, the native bismuth has been partly replaced with maldonite. Jonassonite and Pb–Bi sulphosaults (mainly, cosalite Pb2Bi2S5) were formed later in these ores. The overlaying Sb mineralization has given formation not of antimonite (stibnite), but of Pb–Sb sulphosaults (moeloite Pb6Sb6S15, etc.), pseudomorphs of chalcostibite after chalcopyrite, as well as aurostibite AuSb2 after minerals of gold. The replacement of maldonite by aurostibite was resulted in appearance of bismuthate III. The probable replacement reaction is: 2Au2Bi + 6Sb solv. + + 3Sb2S3 solv. → 4AuSb2 + Bi2S3. Bismuthite III (Bi1.72–1.96Sb0.29–0.94)2(S2.98–3Se0–0.02)3, containing 1–7 wt % of Sb, is a product of the maldonite replacement by aurostibite. Moeloite and stibian bismuthate III arose by the Sb mineralization overlaying ores with cosalite. The probable replacement reaction is: 3Pb2Bi2S5 + 3Sb2S3 solv. → Pb6Sb6S15 + 3Bi2S3. Stibian bismuthite-III contains 4–17 wt % of Sb in its composition (Bi1.36–1.71Sb0.64–0.29)2S3. Appearance of bismuthite with the Sb mineralization where it was developed over ores with native bismuth, maldonite and Pb–Bi sulphosaults is the evidence of key role of the mass action law in mineral-forming processes.

Contamination in Mineralogy: Pathways and Effects

Contamination is considered as the ingress of material into an object that is not characteristic of this object. From this point of view, technogenic contamination, associated with human activity, and natural contamination, not depending on humans, are distinguished. The study of contamination is relevant in relation to the research process: neglect or misunderstanding of this phenomenon can lead and often lead to erroneous conclusions, forecasts, and estimates regarding the objects of study. Contamination does not necessarily have a negative meaning, and both types of contamination can be useful. Both types of contamination are considered on specific examples.
Minerals of the Supergroup of Alunite in Layered Ores of the Yaman-Kasy Sulfide Deposit, Southern Urals: Morphology, Assemblages, and Chemical Composition

The article describes the findings of minerals of the alunite supergroup: crandallite, ginsdalite, and alunite in hematite-containing thin-layered pyrite ores with increased total REE contents (up to 110 ppm). Crandallite forms elongated aggregates (up to 120 microns) with a rhythmically zonal structure and an uneven distribution of REE in them. Less common are spherulite aggregates (up to 120 microns) in association with alunite, quartz, chlorite, and hematite. The main feature of crandallite is high Pb contents (7–19 wt % PbO). Individual grains of crandallite contain (wt %) up to 1.84 La2O3, up to 1.03 Ce2O3, 0.85–1.73 Nd2O3, 0.39–0.54 Pr2O3, as well as 0.52–2.70 BaO, 0.99–2.50 SrO, 0.34–0.55 UO2, 0.30–0.69 ThO2, and 0.32–0.57 CuO. Ginsdalite and alunite in the form of spherulites up to 30 microns in size and lamellar aggregates up to 20–30 microns in length are found in interstitials of chalcopyrite, barite. The chemical composition of alunite and ginsdalite contains minor V2O5 (up to 0.3 and 0.1 wt %, respectively). The formation of minerals is considered as a result of the mobilization of components from hyaloclasts and ore-clasts in the presence of phosphorus coming from biogenic matter during the formation of a late quartz-hematite association.
Neotocite from Manganese Ores of the Ushkatyn-III Deposit, Central Kazakhstan

Neotocite, an X-ray amorphous hydrous manganese silicate is the mineral characteristic for low-grade metamorphosed sedimentary manganese ores of Ushkatyn-III deposit in Central Kazakhstan. It occurs both in the groundmass of ores, with hausmannite, tephroite, caryopilite, friedelite, pennantite, rhodochrosite, kutnogorite, and in veinlets crossing these ores. In veinlets, segregations of homogeneous neotocite reach several cubic centimeters. The study of such large segregations allows to characterize optical, mechanical and thermal properties, IR spectra, and chemical composition of neotocite using modern analytical methods. It is assumed that manganese in neotocite is mainly (or even completely) divalent. The stoichiometry of the mineral, taking into account chemical, thermal analyzes and IR spectroscopy data, corresponds to the ideal formula Mn7(Si8O20)(OH)6∙nH2O. This formula reflects correctly the ratio of silicon and manganese in the mineral, its layered crystal structure and at least two different forms of H-bearing: in (OH)-groups and H2O molecules. The above given formula of neotocite could be accepted as the idealized one. Neotocite was formed at low temperatures and in reducing conditions during the sedimentary burial of metal-bearing deposits containing a Mn–Si–H2O substance (gel?), or later – due to hydrothermal alteration of already formed manganese ores.
Geochemistry of Spring Water of Mzymta and Sochi River Basins, Southern Slope of the Caucasus Ridge

The chemical composition of the waters of 31 springs located in the basins of the Mzymta and Sochi rivers on the southern slope of the Caucasus Range was studied. Both water-bearing fractured carbonate rocks and water-resistant mudstones and igneous rocks are developed here. In addition, the region is characterized by the development of mineralization zones and deposits of thermal hydrogen sulfide waters. Four types of waters have been identified: I) hydrocarbonate calcium, II) hydrocarbonate-sulfate calcium-magnesium, III) hydrocarbonate-sulfate calcium-sodium, IV) hydrocarbonate-chloride-sulfate calcium waters. Due to the geochemical features of regional rocks, all types of waters are characterized by high contents of Se and rare earth elements (REE) and low concentrations of Tl, Zr, Th, and Fe. The first type of waters is associated with fractured carbonate rocks, and due to their good solubility and water permeability, it differs from other types of waters by increased concentrations of Se and REE by factors of 2.3 and 2.6, respectively. The second type, distributed mainly in argillites, is distinguished by relatively low contents of Se, REE and other elements, which is due to the lower water permeability and solubility of argillites compared to carbonate rocks. The third type is characterized by the additional presence of excess elements Ba, Li, Rb and B in the composition, which is associated with the influence of a deposit of hydrothermal mineral waters. Igneous rocks, being the least permeable and less rich in chemical elements than mudstones, influence the formation of groundwater with the lowest concentrations of elements. The low permeability of igneous rocks is confirmed by the analysis performed using the hydrogeochemical Gibbs diagram, indicating that the precipitation factor is superimposed on the formation of these waters. REE for all types of waters are characterized by similar fractionation inherited from the rocks of the region (medium REE heavy REE light REE). The total amount of rare earth elements and their fractionation patterns can be used as a reliable criterion for the interpretation and typification of fresh groundwater.
Factors Affecting Intention to Use Blockchain Technology in Health Records in Saudi Arabia: A Case Study of the Eastern Province

The study aims to measure the impact of the combined independent factors (technical skill level of users, technical infrastructure, ease of use, security privacy, perceived benefit, and perceived risks) on the trend to use blockchain technology through the study of the attitude towards the use of blockchain technology. This study relies on the quantitative descriptive approach using a questionnaire. The sample population consisted of workers in the health sector in the eastern region of the Kingdom of Saudi Arabia, where the responsive sample amounted to n = 256. Results showed that there is a strong positive correlation at the significance level (α≤0.05) for the combined independent factors on the attitude towards the use of blockchain technology. The results of the model path quality efficiency test indicators also mostly showed ideal values. Thus, we conclude through these indicators that there is a positive impact of the combined independent factors (technical skill level of users, technical infrastructure, ease of use, security privacy, perceived benefit, perceived risks) on the orientation to use blockchain technology at the significance level (α≤0.05). The study recommends the need to continuously develop the technical infrastructure to keep pace with recent and rapid changes in information technology, such as health record systems, based on blockchain technology, which allows easy data sharing between healthcare service organizations and beneficiaries while maintaining the privacy and security of data in providing the best services.
A Study on The New Ideas of Higher Vocational Physical Education Teaching Reform from The Perspective of Multimedia

In recent years, the development of information technology is very rapid. It plays an increasingly important role in people's life and social production, and promotes the progress and development of society to a certain extent. Under the new situation, higher vocational colleges should actively try to use multimedia technology to carry out teaching work, to improve their teaching level and lay a solid foundation for the future development of students. However, it is worth noting that at this stage, some teachers in higher vocational physical education have less knowledge and understanding of multimedia technology, and can not give full play to the role of new media in the teaching process, which is not conducive to the improvement of physical education teaching level. This paper studies the application value and application direction of multimedia technology in Higher Vocational Physical Education, and combs the reform ideas of Higher Vocational Physical Education from the perspective of multimedia, to bring some help to the reform of physical education in higher vocational colleges.

With the rapid development of digital media technology, the education sector is paying more and more attention to the transmission and dissemination of traditional culture, and the digital media platform provides a wide range of opportunities to achieve this goal. This study provides an in-depth discussion on several dimensions, including theoretical foundations, element selection, interpretation methods, and challenges and opportunities. Firstly, we explore the definition and importance of traditional culture, as well as the concepts and trends in digital media teaching and learning, emphasising the intrinsic connection between the two. Subsequently, we describe the methods and criteria for selecting traditional cultural elements, and analyse in detail the application of digital media tools and techniques in reproducing traditional cultural elements. The study delves into the application of the theory of cultural interpretation, as well as the reproduction and transfer of meaning of cultural elements in digital media teaching. We discuss issues related to challenges and opportunities, including the balance between cultural adaptation and cultural protection, intellectual property issues, and future trends. Finally, we summarise the key findings of this study, highlight the importance of traditional cultural elements in digital media teaching and provide relevant recommendations. Through the in-depth discussion in this study, we expect to provide useful thoughts and guidance on the inheritance and innovation of traditional culture, as well as contribute new perspectives and insights to the research and practice in the field of digital media teaching.
Degree of facial profile convexity using Subtelny’s analysis in patients aged 6 to 12 years

Skeletal malocclusion is caused by a disproportion of the maxilla and mandible, which leads to an unharmonious facial profile. Straight, convex, and concave soft tissue profiles may serve as a guide to determine the underlying skeletal relations and location of the jaws from the anteroposterior plane. In this study, Subtelny’s cephalometric analysis of the skeletal and soft tissue profile is used to evaluate the facial profile convexity and is divided into three parts, which are the skeletal profile convexity, soft tissue profile convexity, and total soft tissue profile convexity. The purpose of this study is to determine the degree of facial profile convexity according to Subtelny’s analysis in patients aged 6 to 12 years at Faculty of Dentistry Dental Hospital of Trisakti University. This was a descriptive observational study using samples of cephalograms of 40 patients aged 6 to 12 years. Cephalometry tracing and identification of anatomical landmarks were done to acquire the facial profile convexity degrees. The anatomical landmarks used were nasion, A-point, pogonion, soft tissue nasion, subnasale, pronasale, and soft tissue pogonion. The results of this study found that the average degree of the skeletal profile convexity was 171.26°, the soft tissue profile convexity was 166.18°, and the total soft tissue profile convexity was 144.83°. The degrees of skeletal profile convexity, soft tissue profile convexity, and total soft tissue profile convexity could be influenced by age, gender, and differences in growth and changes in the skeletal and facial soft tissue structures.
Study on the Exposure to E-Learning during COVID-19: Special Reference to Management Undergraduates of Non-State Universities

Education is a goal of every human being in this modern era. The remarkable growth in information technology and the internet over the past few years has propelled the need for the application of e-learning among the educational sectors. Due to the recent outbreak of the COVID-19 pandemic, Sri Lankan educational institutes were forced to transform to e-learning. Hence, it is essential to have a strong awareness on the engagement of students in this e-learning. The purpose of this study is to examine the level of exposure to e-learning with special reference to the management undergraduates of non-state universities in Sri Lanka. This study is a quantitative research study and is based on a deductive research approach. For data collection, researchers used a questionnaire based on a convenience sampling process. A sample of 332 students was considered from a total population of 2500 students including 3rd and 4th year management undergraduates from two non-state universities. The collected data were analysed using one sample t-test analysis and descriptive analysis using the Statistical Package for Service Solutions. The researchers used one sample t-test to predict the students' level of exposure to e-learning based on the mean value of e-learning. The results show that students had a high level of exposure to e-learning with a value of 3.92. In addition, it revealed that system quality, instructors’ quality, digital readiness and learners’ attitude are highly influential towards the students’ level of exposure to e-learning. Furthermore, descriptive analysis revealed that the average GPA achieved by undergraduates utilising e-learning is higher than by traditional learning with an average score of 3.35. The findings of this study can serve as a guideline for higher educational institutions in developing appropriate initiatives to uplift the e-learning exposure. The main limitation of the study was that only management undergraduates were taken into consideration. As a result, future researchers should focus their efforts on different faculty studies separately to explore the level of e-learning exposure in each one of them.&#x0D; Keywords: COVID-19, E-Learning, Exposure, GPA, Undergraduates
