The problems of state registration of amusement parks in the Russia and the implementation of control (supervision) over the activities of their operators
Authors: Lomov Ivan Sergeevich
Published: November 2024

Providing entertainment services to the public is an integral part of the general economic activity of entrepreneurship and business in the Russian Federation. The use of attractions for such purposes is a sought-after and profitable occupation, although it is fraught with high danger and risks. Since the early 2000s, the number of individual entrepreneurs and legal entities operating amusement rides has been growing in the Russian Federation, along with the growing number of consumers of such services, the vast majority of whom are incapacitated children. Every year, thousands of attractions of various types are operated throughout the Russian Federation, located outside and inside the premises, on water and land, having a mechanized and non-mechanized type of operation. The main problem is the legality of their work in terms of compliance by operators with all available safety requirements. Unfortunately, cases of various failures in the operation of attractions related to the negligence of those responsible for their safe operation and technical malfunctions are not uncommon, and have serious consequences for the life and health of entertaining visitors. The Government of the Russian Federation, realizing the importance of regulatory legal regulation of this area, has been developing a whole layer of legislation since 2016. Our research is designed to describe and identify the problems of two main areas of such regulation: state registration of attractions and control (supervision) over the activities of individual entrepreneurs and legal entities operating attractions. The main objective of the study is to make proposals on changing the current legislation governing the safe operation of attractions. The scientific novelty lies in the fact that the study offers the legislator ways to solve the accumulated regulatory problems related to the work of the State Technical Supervision bodies of the Russian Federation as a public authority exercising control (supervision) and state registration of attractions. Such proposals are unique in the scientific community and have not been described before by the authors of the research, since the regulatory sphere of public regulation of the safe operation of attractions is extremely young and requires further normative development.
Stability of the Constitutions of the Republics within the Russian Federation: theoretical and practical aspects
Authors: Safina Svetlana Borisovna
Published: November 2024

The object of the study is the constitutions of the regions (Republics) within the Russian Federation. The subject of the study is the properties of stability of the constitutions of the republics within the Russian Federation. These properties of regional constitutions are analyzed taking into account the fact that they are part of the legal system of the Russian Federation and are an element of the Russian legislative system. The article examines the legal foundations enshrined in the constitutions of the republics, the regulatory mechanisms for ensuring the stability of constitutional texts, their practical implementation and the degree of validity of their introduction. The relevant norms of federal legislation and constitutions of the constituent republics of the Russian Federation are analyzed. Based on the analysis of legal sources, theoretical provisions are formulated on the importance of the "rigidity" of constitutional procedures (complicating elements in the procedure for changing constitutions) in ensuring the stability of republican constitutions. The research uses general scientific (logical, analysis and synthesis, etc.) and private scientific legal (comparative legal, formal legal, etc.) methods. The article updates the views on the development of the processes of constitutional changes at the level of the republics within the Russian Federation, taking into account the realities that have occurred. It is noted that the Constitution of the republic, as an act that enshrines the basic, fundamental principles and priorities of the republic's development, should be provided with increased legal protection in order to prevent short-term market changes. The legal protection of the Constitution includes, among other things, a complicated procedure for its correction. It is concluded that the republics are independent in this matter, since the federal legislator does not regulate this area. The stability of the republican constitution is largely determined by the federal Constitution and federal legislation, and when choosing the means of "rigidity" of constitutional procedures, it is necessary to take into account the nature of republican norms: whether they reproduce, concretize or complement federal ones.

On the varieties of the official functional style of the English language
Authors: Malyshkin Dmitriy Vladimirovich
Published: November 2024

The subject of the study are sets of linguistic units that convey different types of content. The purpose of the paper is to study the official functional style in connection with its internal heterogeneity. Although functional stylistics has received a detailed description as a philological discipline which concerns itself with the varieties of developed literary languages, the issue of the internal heterogeneity of functional styles still remains unresolved. The novelty of the paper lies in the fact that it shows the heterogeneity of the official functional style. The practical significance of the work is due to identifying the varieties of the official functional style, which is carried out in the paper and which helps to optimize the choice of teaching material depending on the needs and on the general linguistic competence of students. To solve the task, an integrated approach to the study of the material was chosen: the method of linguostylistic and functional-stylistic analysis, the method of continuous sampling, the descriptive-analytical method, as well as the comparative analysis of texts. It has been established that texts belonging to the official functional style can be divided into three groups (prescriptive official texts; descriptive official texts; evaluative official texts) in accordance with the proportions of linguistic components that perform the main functions of language and render a certain type of content.

Authors: Abdrahmanova Florida Rivhatovna
Published: November 2024

The subject of this study is the ethical problem of moral conflict in the modern world, in which traditional moral values clash with the values of the information society, caused by the hypertrophied development of Internet technologies and media space. The main problem of the study is an attempt to understand the conflict of moral values in the era of Big Data through the prism of philosophical analysis by applying the hermeneutic method and its ethical solution. The idea that traditional moral values cannot be assimilated in information flows, but must be transformed and developed taking into account the realities of modern digital society, is central to the study. The research methodology includes theoretical methods, such as ethical and philosophical analysis of the problem, the hermeneutic method, which allow to go beyond the description of the functionality of the latest technologies, and understand what impact they have on the transformation of moral values in modern society. The scientific novelty of the study lies in the fact that the article reveals new aspects of using the hermeneutic approach to the analysis and interpretation of the conflict of moral values of interaction between humans and digital technologies in modern society. The results of the study show that moral values and ethical norms must adapt to the modern realities of the information society in order to preserve human identity. The hermeneutic approach made it possible to consider the problem from the point of view of a person's personal growth, preserving their own identity and searching for truth in a world overflowing with information.

Published: November 2024

Phenolic compounds are extensively used in environmental protection, food safety, and human health, making their detection a critical concern. Hydroquinone, a widely used isomer of dihydroxy benzene, is classified as a priority pollutant by the US Environmental Protection Agency (EPA) and the European Union (EU). In this study, we developed a robust and sensitive method for detecting hydroquinone (HQ). The sensor was created by sequentially depositing Titanium carbide (Ti3C2Tx, MXene) and L-alanine on a glassy carbon electrode (GCE). The sensor demonstrated a linear correlation between current and concentration in the range of 30 × 10−6 mol L−1 to 100 × 10 −6 mol L−1. Additionally, pH and scan rate optimizations were performed to achieve the best affinity conditions between the analytes and the electrode surface.
Adaptive Learning Reaction Pathways Search
Authors: Makos Malgorzata Z , Zhang Difan , Rosseau Roger , Glezakou Vassiliki-Alexandra
Published: November 2024

Computational simulations have become essential for understanding reaction mechanisms, identifying optimal catalysts, studying materials, and discovering chemical pathways. Even with the current advanced computational resources, determining competing reaction pathways and the associated transition states is extremely challenging. The problem is further exasperated as the system size increases due to the increasing number of comparable energy isomers and intermediates. In this work, we present a novel computational protocol to efficiently explore the potential energy surface and identify reaction pathways, by combining an adaptive learning global optimization procedure and neural networks for predicting transition states. For a given reaction, the global optimizer is first used to obtain putative low-lying minima in the basins of reactants and products. In the second step, generative adversarial networks (GAN) are used to estimate the transition states that connect any two initial and final states of a given reaction. This computational interface (GlobOptRx) can quickly identify the transition state structures along a reaction pathway and aid in the discovery of new reactions, determine generalized systems descriptors and facilitate the construction of kinetic models.
New gravimetric method for determination of total dissolved solids and percentage extraction for coffee-chicory mixture
Authors: U Raksha , Harohally Nanishankar
Published: November 2024

Coffee-chicory mixture is consumed widely in India and few parts of USA, France. Although chicory is a coffee surrogate, its use is widespread across India, due to ease of brewing along with coffee when south Indian filter is employed. The comparison of beverage brewed from coffee-chicory mixture has hardly attracted any attention from point of view of total dissolved solids (TDS), percentage of extraction (PE)and in general the relative contribution of each to total beverage composition. As suitable methods are not reported for determination of TDS and percentage extraction for brewed beverage from coffee chicory mixture, we herein, report a new method for the determination of TDS and percentage extraction based on gravimetry.
Molecular Cages as Encapsulants for the Stabilization of Reactive Iron-Sulfur Cofactor Models
Authors: Baliyan Rupal , Bailey Gwendolyn
Published: November 2024

Iron-sulfur clusters are desirable targets for bioinspired synthesis due to their versatility in promoting a range of catalytic reactions (N2 reduction to NH3, CO2 reduction to hydrocarbons, and selective C–H functionalizations) and ability to serve as model systems for the systematic interrogation of structure and mechanism. However, a challenge in replicating the activity of clusters remains their instability outside of the protein scaffold. Previous efforts to mitigate this challenge include incorporation into polymeric and aerogel networks and artificial metalloenzymes or installation of bulky, strong-field ligands, but none of these retain both the native weak-field primary ligand sphere and capacity for molecular-level tuning of the cofactor and second coordination sphere. Herein, we present a new strategy for stabilizing weak-field synthetic clusters and conferring second coordination sphere functionality via encapsulation inside molecular cages. Thus, clusters [Fe4S4(SR)4]2– ([1a-c]2–: R = Ph, CH2CH2OH, tBu) are encapsulated inside tetrahedral naphthalene diimide (NDI)-functionalized cages [M4L6]8+ (M = Fe, Ni, Zn) via a robust and generalizable electrostatic binding strategy. 1H and DOSY NMR, ESI-MS, and 57Fe Mössbauer studies confirm immediate and quantitative binding and suggest the cluster electronic structure is minimally perturbed by the cage. At the same time, the cage’s redox-switching ability is demonstrated in CV and 57Fe Mössbauer studies demonstrating that NDI reduction renders the encapsulated cofactors [1a-b]2– significantly more reducing, consistent with their effective charge donation to the cofactor via pi-pi stacking and H-bonding interactions. Importantly, cofactor reactivity is maintained as demonstrated in diphenylacetylene reduction trials, showing that the encapsulated clusters are not only structural but also functional cofactor models. Combined, these results demonstrate that molecular cages can function as protein-like encapsulants to site isolate, tune, and deliver substrate to functional weak-field models of bioinorganic cofactors, and support the use of molecular host-guest complexes as functional enzyme mimics for both catalytic and structure-function studies.

Authors: Huang Jun , Huang Baihua
Published: November 2024

The presence of Hailao porcelain in the world is widespread, with historical, economic, practical, artistic, and other functional attributes, so its comprehensive benefits cannot be underestimated. The development of modern science and technology, and the reasonable and effective development of Hailao porcelain in different times, are conducive to the development of China’s cultural construction. Because Hailao porcelain is different from the traditional ancient porcelain (handed down and unearthed), it is a new cultural research field. This marine wealth has great economic, cultural, and historical value, and plays an important role in the cultural construction and social development of the country in the new period. The cultural efficacy covered by the ancient shipwreck Hailao porcelain includes the functions of inheritance, cognition, education, communication, and so on, which is conducive to the current cultural development. People can use the new perspective and new concept of cultural and creative thinking to make these cultural relics “alive”, give play to the new cultural value, promote the economy of cultural relics and works of art, serve the spiritual and cultural life, and strengthen the cultural exchanges and cooperation between China and other countries in the world.

Authors: Shi Lei , Huang Ling , Fang Tong
Published: November 2024

This paper reviews the research progress in the synthesis of N-acyl amino acid surfactants, including chemical synthesis methods, enzymatic synthesis methods, chemo-enzymatic methods, and fermentation methods. Chemical synthesis is currently the main route for laboratory and industrial synthesis, including methods such as direct dehydration condensation of fatty acids, amidation of fatty acid anhydrides, carbonyl addition of fatty amides, amidation of fatty acid activated esters, amidation of fatty acid methyl esters, amidation of oils and fats, hydrolysis of fatty nitriles, and Schotten–Baumann condensation. Enzymatic synthesis has the advantages of mild reaction conditions and being green and pollution-free, but the yield is relatively low. The chemo-enzymatic method combines the advantages of enzymatic and chemical methods, but it has not been widely promoted. Fermentation methods have low production costs and are environmentally friendly but the technology is not yet mature. This paper elaborates on the principles, advantages, and disadvantages of each synthesis method and provides an outlook on future research directions.

Authors: Ai Lixin , Wang Yingchun
Published: November 2024

Objective: The purpose of this study was to investigate how perceived social support from coaches leads to favorable coach-athlete relationships via the mediation of coach-athlete attachment and the moderation of proactive personality. Method: The study consisted of a cross-sectional self-report survey with a sample of 302 professional athletes recruited and measured by psychological questionnaires of perceived coach social support, coach-athlete attachment, coach-athlete relationship, and proactive personality. The structural equation model examined the moderated mediation model. Results: The results indicated that coach-athlete attachment partially mediated the prediction of perceived coach-social support in the coach-athlete relationship. Proactive personality played a moderated role between perceived coach social support and coach-athlete attachment. Conclusions: This study suggests that coaches should pay more attention to athletes to build up the coach-athlete relationship, while they also need the athletes’ positive feedback.
Causation or Canard: Use of Brain Weight to Body Weight Ratios in Developmental Neurotoxicity
Authors: Crofton Kevin
Published: November 2024

Abstract
DNT guideline‐based testing requires the assessment of neurologic, behavioural, and neuropathological endpoints. A review of the impact of DNT studies on regulatory actions revealed that the most common findings at the LOAEL were change in body weight, motor activity, auditory startle response, brain weight and brain morphometrics. An important issue in the interpretation of DNT study findings is that in many of these studies use exposures that impact systemic development as evidenced by decreased body weight and/or body weight gain, especially during the early postnatal period prior to weaning. Currently, there is no international consensus on what degree of growth reduction during early development causes alterations in DNT endpoints. This includes the controversial use of changes body weight adjusted brain weights in concluding that the brain weight changes represent an adverse finding. The current effort compiled brain and body weight changes from 173 publicly available DNT studies designed in line with DNT EPA or OECD test guidelines. This allowed a simple comparison of between a decrease in neonatal body weight and a decrease in brain weight. Results from this project clearly show that developmental exposure induced body weight decreases are not a reliable indicator of whether or not brain weight decreases. From the 173 retrieved studies, 70% showed decreased body weights in pups (122 studies), but only 50 of these studies (41%) reported concomitant decreased brain weights. In addition, there were three studies that reported brain weight decreases when body weight was not changed at any age. This suggests that while changes in body weight may be a confounding factor for some studies, it fails to be a reliable predictor of alteration in brain weight. Thus, use of the ratio of brain weight to body weight is not appropriate as a common approach to dismiss brain weight as a DNT effect. Clearly an international consensus on the interpretation of brain weight changes in DNT studies is needed that takes into account the data presented herein.

This paper presents the preliminary results of two field trials where a novel percussion sidewall core acquisition tool was deployed. The work continues the development of the new core acquisition technology previously presented by Draper et al. (2022) and Lakshtanov et al. (2022). This technology leverages digital rock physics (DRP) to assess core quality. A novel percussion sidewall core acquisition method was trialed in two appraisal wells targeting carbon capture and storage (CCS) prospects. The percussion bullets used included an internal sleeve that protects the core samples from handling damage during extraction and analysis. The percussion sidewall sampling was part of an extensive evaluation program that also included whole core and rotary sidewall core acquisition. Coring program targets were sandstone intervals predicted to have low unconfined compressive strength (UCS), and core recovery was expected to be a challenge. The novel percussion method was deployed to test the acquisition technology under real field conditions and provide a basis for validating the merits of the method against conventional coring and core analysis methods. Percussion core samples were acquired during individual wireline runs in two field trial wells. On the first well, tool problems unrelated to the novel bullet design resulted in core recovery, which was lower than expected. Modifications were applied, and very high core recovery was achieved on the second well. High-resolution X-ray micro-computed tomography (micro-CT) images of the core samples indicated that a suitable volume of material was available for DRP and conventional percussion core sample analysis. Preliminary assessments indicate that the method is competitive with other rock sampling methods in terms of cost, risk, and value. Deployment of a novel percussion sidewall coring technology in two field trial wells has demonstrated the applicability of the sleeved bullet concept to real downhole conditions. DRP and conventional evaluation of the core samples have shown that samples are of good quality and can yield critical reservoir characterization information. The novel percussion coring technology addresses several historic challenges to characterizing soft (low UCS) formations. Combined with DRP and conventional core analysis, this technology offers a cost-effective and efficient method of reservoir characterization.

Published: November 2024

The purpose of the work is to assess the effects from introduction of the automated mining process control systems (AMPCS) and to develop recommendations for their further development in the industry. The research methodology includes: 1) analysis of the functional features and architecture of contemporary AMPCSs; 2) collection and statistical analysis of data on the key performance and safety indicators for enterprises that have implemented the AMPCSs in comparison with the reference group; 3) development and validation of mining process optimization models based on the AMPCS data using the machine learning and operations research methods; 4) execution of an expert-level survey to identify the success factors and barriers in implementation of the AMPCSs. The results have shown that introduction of the AMPCS provides a significant improvement of the key performance indicators (15-20% increase in labour productivity, 10-15% reduction in unit costs) and the key safety indicators (20-25% reduction in accidents minimized downtime) of mining enterprises. The developed optimization models demonstrate high efficiency when using real data.

Authors:   S.A. Zhukova1, O.G. Zhuravleva1, V.S. Onuprienko2, A.A. Streshnev2
Published: November 2024

The article presents the results of studying seismicity during the advancement of mining operations to deep horizons using the case of the Kukisvumchorr apatite-nepheline deposit (the Khibiny massif). Mining of underground reserves of the investigated deposit is complicated by the presence of the Saamsky open pit and the adjacent Yukspor deposit. The study focuses on assessing the area distribution of the seismic event energy flow as the mining operations progress to deep mine levels. Zones of higher values of seismic energy flow density at the lower mine levels were identified as mining operations progressed to deeper levels and developed towards the Saamsky open pit. The results are presented as isoline maps, which helped to identify areas of different levels of seismic energy flow distribution. A classification of seismicity levels according to the seismic energy flow parameter was proposed for the conditions of underground mines of the Kirovsk Branch of Apatit JSC, i.e. the background, background elevated, high, and extremely high seismicity levels.

The article shows that the danger of karst formation in the upper part of the section is enhanced due to the frequent filling of karst cavities with gas at abnormally high pressure, generating gas-dynamic processes that destroy the roof of the cavity and lead to gas blowouts/explosions. The results of a four-year monitoring of the Dedilovsky karst sinkhole development in the Tula region (formed on May 8, 2019) using the DJI Mavic Pro unmanned aerial vehicle were presented, during which 12 multi-temporal aerial photographs were taken and 12 three-dimensional (3D) models were built in the period from May 18, 2019, until June 1, 2023. The maximum change in the sinkhole outlines along the surface of the earth in the northwestern directions was established at 6.4–7.8 m towards the residential building. It is shown that aerial photography of hazardous objects from unmanned aerial vehicle with subsequent photogrammetric data processing allows you to quickly create digital 3D models and study the ongoing geodynamic, geological and environmental processes.

The article analyses efficiency assessment of mining excavators using the case study of mining operations of the Republic of Uzbekistan. The index of target productivity is used as an assessment criterion, which definition methodology takes into account the negative influence of the operation factors on the value of productivity loss in basic operating conditions. Climate, mining and geological and mining engineering conditions, organization of the mining operations, the quality of the face and rock mass preparation, ergative factor of management as well as maintenance and repair are considered as the impact factors. A weighting coefficient of the impact factor is introduced in order to adjust the value of losses in given operating conditions. The value of the weighting coefficient is justified based on long-term observations of specific conditions features and modes of operation, maintenance and repair of excavators in the quarries of Uzbekistan, expert opinion and open source data. A ray-path chart of the efficiency preservation coefficient of the EKG-20K excavator as a widely used excavator within the excavator fleet renewal programme at Uzbekistan enterprises, was plotted for the worst scenario and for the Kalmakir, Yoshlik and Muruntau open pit mines. As a result, an achievable level of the target productivity of the ECG-20K excavator is estimated for the considered open pit mines.

Mining of coal deposits leads to forming outburst-prone areas, which are prone to sudden emissions of coal, rock and gas into mine workings. These sudden outbursts can result in severe accidents that are often fatal. As a rule, outbursts occur at high speeds, sometimes exceeding the speed of sound. From the point of view of gas dynamics, a gas outburst is a disturbance that creates a shock wave in the quasi-stationary mine atmosphere, the intensity of which depends on the velocity of the outburst gas. The shock wave is capable of injuring miners, destroying the mine support and ruin mechanisms and technological equipment located in the vicinity of the outburst. In this regard, the problems of the gas-air mixture flow caused by a sudden outburst seem to be highly relevant, both from the scientific and practical point of view. This article considers the problem of the gas–air mixture flows with viscous and dispersive properties, described by the Korteweg–de Vries–Burgers partial differential equation, which closed-form solution is presented in the paper. Computational procedures were used as the basis to build the graphs that characterize the flow conditions of the gas-air mixtures at various parameters of their viscosity and dispersion. The graphs were analyzed and a number of patterns were revealed in the flow of the gas-air mixtures.

The article presents a method for measuring the detonation characteristics of emulsion explosives and express determination of the strength properties of rocks for the complex adaptation of drilling and blasting parameters to the changing mining and geological conditions of the development of complex-structured mineral deposits by an open method. The developed technique allows: to set the parameters of the recorded signals during the spherical drilling of wells, characterizing violations in the places of contact of rocks with various physical and mechanical properties; to determine, within the framework of pilot tests, the patterns of detonation development in sleeve and borehole explosive charges of different diameters, as well as when using intermediate detonators with different weights; to establish the locations of the rational location of intermediate detonators during the counter initiation of borehole explosive charges. Data on the process of spherical drilling of wells at a local excavation unit is obtained using an experimental device installed on a drilling rig, developed by specialists of IM UB RAS. Measurements of the detonation rate in industrial conditions at a special landfill or in a quarry are carried out with equipment of domestic and foreign production. Based on the measured data, regression equations are established by construction. The obtained equations make it possible to determine the value of the detonation rate of the charge of an emulsion explosive at a known charging density, which makes it possible, by adjusting the density when mixing explosive components, to provide the necessary detonation pressure for the qualitative destruction of a specific rock mass.

The stress-strain state of the rock mass at the International mine has been assessed for mining the reserves of its upper levels. Options of the mining system that is most suitable for these conditions have been considered, i.e. a slicing method with consolidating stowing of the mined-out space and the room-and-pillar order of mining within a layer and the ascending order of layer excavation, as well as a system with induced sublevel caving of the ore and the host rocks. Mathematical modeling of changes in the stress-and-strain state of the rock mass have been performed for the selected mining method at different mining stages. It is shown that the stresses arising in the ore mass within the zone of mining operations will not lead to loss of strength and destruction of the structural elements of the mining system, and therefore, the proposed mining options will allow to excavate the reserves of the penthouse with a minimal loss of valuable raw materials while ensuring safe conditions of mining operations at the International mine.

In order to assess the seismic impact of large-scale blasts on the rock mass immediately adjacent to the blasted block, measurements of the ground displacement rate in the near zone of the blast action were carried out in various sections of the Zhelezny open pit mine of the Kovdorsky GOK JSC. According to the degree of the the rock mass response to dynamic impacts, the open pit was zoned depth-wise. Three areas of seismicity were identified, for which empirical dependences of the change in the displacement rate on the reduced distance and the corresponding coefficients of seismicity and attenuation were obtained. The sizes of the induced fracture zone were calculated using these dependences in relation to the permissible displacement rate. The average size of the jointed rocks increases with the depth of the open pit: it starts sharply (from 0.22 to 1.19 m) within the interval of 0-150 m from the day surface, then continues gradually (from 1.19 to 1.4 m) down to the depth of 450 m, and deeper stabilizes at the level of 1.4-1.5 m, which gives the difference in the size of the induced fracture zones. An engineering methodology was developed for operational assessment of the seismic blast impact on the boundary rock mass during blasting operations in open pits to calculate the width of the cutter break zones, fracturing into the rear part of the rock mass and zones of induced fracturing. Calculations at the design stage allow selecting blasting parameters that minimize the seismic impact on the boundary rock mass. A software program has been developed for operative calculation of the fracture boundaries position in the rear part of the rock massif during borehole blasts. The obtained calculated values are in good conformity with the previously obtained modeling and application data.
