Compounds of the argyrodite structure are considered to be promising functional materials due to their peculiarities. The functional parameters of these compounds are provided by the peculiarities of the crystal structure, namely the simultaneous coexistence of a mobile cationic sublattice within a rigid anionic framework. Such a crystal structure motif determines the formation of wide regions of solid solutions based on argyrodites and makes it possible to increase the values of the functional parameters of these phases within the homogeneity regions. This work presents the results of the study of the structural and electrical properties of Ag7+xGexP1-xS6 (x = 0.75; 0.5) solid solutions with an argyridite structure. Single-crystal samples of solid solutions of Ag7.75Ge0.75P0.25S6 and Ag7.5Ge0.5P0.5S6 were obtained by the method of directional crystallization from the melt in vacuum-sealed quartz ampoules. It was found that the solid solutions of Ag7+xGexP1-xS6 (x = 0.75; 0.5) crystallize in orthorhombic crystal system: SG Pna21, with lattice parameters: a = 15.093 Å, b = 7.462 Å, c = 10.571 Å (Ag7.75Ge0.75P0.25S6) and a = 15.023 Å, b = 7.450 Å, c = 10.545 Å (Ag7.5Ge0.5P0.5S6). The frequency and temperature dependence of the total electrical conductivity was studied by impedance spectroscopy. The total electrical conductivity of the investigated single crystals is Ag7.75Ge0.75P0.25S6 5.43×10–3 S/cm (0.199 eV) and Ag7.5Ge0.5P0.5S6 2.22×10–2 S/cm (0.152 eV) at a temperature of 25 °C.

Published: March 2024

Introduction

Ocular ischemic syndrome (OIS) is a rare condition associated with ocular hypoperfusion caused by carotid artery occlusive disease. This article describes the case of a patient who was admitted to the Department of Ophthalmology at UCK in Katowice, Poland, due to significant loss of visual acuity and pain in the right eye.

Materials and Methods

Retrosopective case report.

Results

Patient showed up in the ophthalmological emergency department complaining of significant loss of visual acuity and pain in the right eye persisting for 2 weeks. The patient had a history of type II diabetes mellitus, hypertension, status post ACS and PCI, and long-term nicotinism. Examination of the right eye revealed ocular irritation, mixed conjunctival injection, hyphema in the anterior chamber, iris neovascularization, and discrete central retinal fading. Additional examinations were performed, including an angioCT, which showed a long-standing obstruction of the right internal carotid artery, a ballooning thrombus in the lumen of the brachiocephalic trunk, and suspected critical stenosis of the left vertebral artery.

A neurologist and vascular surgeon were consulted, and treatment was instituted to limit further complications from the underlying disease. The patient remains under close supervision of the vascular surgeon and neurologist.

Conslusions

OIS is a rare but potentially blinding condition and should be considered in the differential diagnosis of transient visual acuity reduction or vision loss.

Mental Disorders and Crime: An Introduction to Clinical Criminology
Authors: Kipāne Aldona
Published: March 2024

The importance of criminological research is increasing nowadays. Crime is the most dangerous form of deviance and has the most severe social consequences. Combating crime would not be conceivable without the theories and knowledge of criminology. The application of theoretical knowledge in practice should be promoted in criminological research. The manifestations of crime as a socially negative and legal phenomenon are widespread, and social deviations can have completely different forms of manifestation. This is clearly supported by the findings of clinical criminology that evolved from the concept of classical criminology. Clinical criminology is a theoretical and practical study of the personality of a criminal who has committed a criminal offence in a state of mental incapacity or diminished mental capacity, and an approach to determining preventive measures and means..

The objectives of the study were to investigate the quality of maternal and newborn care (QMNC) from the view of mothers who gave birth in a healthcare facility during the COVID-19 pandemic in Latvia. An online questionnaire survey was conducted in Latvia from 1 March 2020 to 28 October 2021, which was based on 40 World Health Organisation (WHO) Standard-based Quality measures. In addition, descriptive and multivariate quantile regression analyses were performed to compare the years 2020 and 2021. A total of 2079 women participated in the study, of whom 833 gave birth in 2020 — of them, 648 had a vaginal delivery, and 185 had a cesarean section, and 1205 women gave birth in 2021, 979 with a vaginal delivery, and 226 with a cesarean section. A lower QMNC during the COVID-19 pandemic was reported by 29.8% and 24.5% of respondents in 2020 and 2021. The total QMNC Index was notably higher in 2021 compared to 2020. This study showed essential gaps in the QMNC in Latvia perceived by mothers, while observing a slight increase in quality in 2021. Therefore, strategies to improve mothers’ and newborns’ health care should be introduced as soon as possible.

Authors: Da Silva Thiago Fernandes , Souza Arthur dos Santos , De Araujo Maria Orlanilda Sousa , França Daniel Batista da Silva
Published: March 2024

Purpose: this work aims to analyze the factors that contributed to the intensification of erosion in the Amazon region of Buriticupu (MA) and discuss possible forms of mitigation and control.
 
Methods: urban area of the municipality was characterized and data on soil, pedology, relief, slope, use and occupation, economic activities developed, as well as satellite images, were collected. This information was used to analyze indicators of natural erosion processes, as well as the influence of human activities. Possible mitigation and control solutions were discussed.
 
Results and discussion: it was found that several aspects contribute to the development of erosion phenomena in the region, such as soil type, slope and hydrology. In the case of the municipality under study, geoenvironmental factors favor the development of gullies. However, the main force has been the action of man in modifying the landscape and weakening the soil. It is understood that it is necessary to implement articulated biogeoengineering strategies, such as controlling the slope and stability of slopes, the water flow regime, plant restoration and environmental education strategies. With this, we can be successful in mitigating the phenomenon and preserving the landscape.
 
Implications of the research: it is urgent to develop shared management measures between federated entities, organized civil society and the local population to map and regulate sustainable development, especially in Amazonian regions.
 
Originality/value: in some Amazonian regions, as in the case of the municipality of Buriticupu (MA), the advancement of agricultural activities and urban development, associated with climate change, have significantly influenced the emergence and advancement of gullies, which can promote the disappearance of the built environment. These gullies are treated as more advanced soil erosion phenomena, serious and difficult to control and remediate. Although erosion is a problem that affects many regions in Brazil, there are still few studies that aim to investigate the causes of its appearance and the discussion about possible solutions applied to gullies in the Amazon region is unprecedented. Agricultural development has accelerated soil degradation and is an urgent problem to be debated.

Introduction. There is no separate register of patients with dysphagia who need an artificial nutritional fistula and enteral nutrition. The situation can be indirectly judged by the data of the information system of the city multidisciplinary hospital in which these operations are performed.

The purpose and objectives of the study. To study the structure of nosology, the order of hospitalization of patients with dysphagia and the ways of applying nutritional fistulas in the city multidisciplinary hospital of St. Petersburg.

Material and methods. The data of the St. Petersburg municipal hospital № 26 information system of cases of gastrostomy and eunostomy in 2021 are analyzed.

Results and discussion. In 2021, artificial nutritional fistulas were applied to 62 patients aged from 20 to 83 years, 63.1±12.64 years in average. In 49 (79.0%) hospitalized patients, the cause of dysphagia was malignant tumors that had already been diagnosed earlier. In 10 (16.1%) cases, patients underwent percutaneous endoscopic gastrostomy using the pull method, while dysphagia was of a functional nature and was a complication of non-tumor diseases. The patients operated by this method were aged from 20 to 80 years, 53.4±20.08 years in average. The imposition of an artificial nutrient fistula through laparotomy was performed in 52 (83.9%) patients aged 43 to 83 years, 64.94±9.90 years in average. All the patients of this group were older than patients, received puncture gastrostomy under the control of an endoscope (p<0.05).

Conclusion. It is necessary to determine the tactics of monitoring of patient with dysphagia and resolving the issue of timely hospitalization for gastrostomy. Planned hospitalization for palliative intervention before the appearance of signs of decompensation of the general condition and obstruction of the upper digestive tract, will allow performing minimally invasive and, as a consequence, low-traumatic puncture methods of gastrostomy.

Purpose  of  the  study.  Assess  the  knowledge  of  medical  professionals  providing  assistance  to  victims with traumatic injuries to the facial skull, obtained in the context of road accidents.  Materials and methods. For  the  study,  a  special  questionnaire  was  developed,  including  11  questions.  The  annotation  involved 100   medical  professionals working in emergency medical teams. Of these, 50  (50%) people with higher education, the corresponding certificate and holding the positions of doctors providing medical care in the city, another 50  (50%)  people who had secondary medical education and worked as a   paramedic providing medical care in rural conditions. Results.  As a  result  of the study, the following results were obtained: most specialists working in emergency medical teams have sufficient knowledge of medical care for injuries to the facial skull, at the same time, most specialists do not have a   specialized  education in dentistry, which does not in all cases help to provide correct and competent care for such sufficiently specific injuries. This can lead to the choice of wrong tactics, which ultimately affects the treatment results of such victims. In this  regard,  pretexts  to  develop  and  introduce  into  practice  specialized  courses  on  the  improvement  of specialists working in emergency medical teams, which would be conducted by specialists in maxillofacial surgery, as well as disaster medicine. In our opinion, this will reduce the number of errors arising in the provision of medical care to such victims.

Published: March 2024

The main purpose of the study was to assess the quality and effectiveness of emergency medical care (EMC)in atrial fibrillation paroxysm (AF) at the prehospital stage. Materials and methods: the analysis included 111 patients who called an ambulance due to AF paroxysm. The patients were divided into groups depending on the recovery of sinus rhythm in the presence of a team. A telephone survey of patients was conducted 30 days after seeking medical help. Results: the sinus rhythm in the presence of the brigade was restored in 40% of cases. At the same time, the median recovery time of the rhythm was 32 minutes [Q1–Q3: 29–50]. 9% of patients were hospitalized. 53% of patients refused hospitalization. The probability of rhythm recovery increased with the help of a medical team and was not associated with the choice of an antiarrhythmic and the use of potassium and magnesium drugs. At the same time, in the next 30 days, complications (hospitalization, recurrence of AF and repeated call an ambulance) were observed more often among patients with restored rhythm (43% vs. 12%;p=0.00022). In 60.5% of patients who were trying to restore the rhythm, No anticoagulants were used, and in 7% 2 anticoagulants were used simultaneously. Conclusion. When providing EMC at the prehospital stage, rhythm restoration in the presence of a team is observed in 40% of cases, which is associated with a large number of complications in the next 30 days and a large percentage of errors associated with anticoagulant therapy.

Authors: Autry Harrison , Gobin Bradley , Marks Ryan , Young Gregory , Anis Afrida , Biswas Prithwish , Shi Keren , Wang Yujie , Zachariah Michael R.
Published: March 2024

A group of five electrically controlled monopropellants were developed, and their fundamental rheological, electrochemical, thermal, and combustion properties were characterized. A baseline monopropellant was composed of lithium perchlorate complexed with polyethylene glycol to form an ionically conductive gel polymer electrolyte. Subsequent candidates were supplemented with varying amounts of ammonium perchlorate at a fixed polymer-to-oxidizer ratio to determine the effects of shifting oxidizer content on the fundamental properties. The ignition of the gel monopropellants using an applied DC voltage potential at atmospheric conditions was observed and determined to be primarily the result of an electrolytic reaction. Time-resolved infrared thermography confirmed initial heating and initiation of the gels at the cathode once temperatures had reached the decomposition temperature of the polymer. Fourier transform infrared analysis of collected residue from experiments halted before ignition revealed lithium deposition on the cathode, supporting electrochemical activity. It was found that the electrolytic ignition delay time was affected by the oxidizer content, the magnitude of the applied voltage, and the distance between the electrodes supplying the voltage.
Fundamental Experiment and Numerical Simulation of Ne/Xe Plasma Magnetohydrodynamic Electrical Power Generation
Authors: Ork Kimsor , Masuda Ryu , Okuno Yoshihiro
Published: March 2024

We conducted experiments in a shock-tube facility to test magnetohydrodynamic (MHD) electrical power generation with Xe-seeded Ne plasma. The performance and plasma behavior of the experimental generator were examined using time-dependent [Formula: see text] two-dimensional numerical simulations. In the experiment, an enthalpy extraction ratio of about 5.0% was obtained using a disk-shaped MHD generator with radio frequency pre-ionization. The numerical simulations show that the enthalpy extraction ratio is improved by adding small amounts of Xe to Ne, but also that adding excessive amounts of Xe deteriorates the generator performance. When an appropriate inlet electron temperature is assumed in the simulations, 5900–6450 K (inlet ionization degree of [Formula: see text]) for a seed fraction (mole % of Xe) of 0.1%, 6050–6280 K [Formula: see text] for a seed fraction of 1.0%, and 5750–5950 K [Formula: see text] for a seed fraction of 5.0%, the plasma structure almost becomes similar to the nonuniform plasma structure observed in the experiment, as too does the enthalpy extraction ratio. The simulations suggest that achieving an inlet ionization degree above [Formula: see text] when using Ne/Xe with a seed fraction of 0.1–1.0% as the working gas should enable an enthalpy extraction ratio above 20%, which is expected to surpass that for pure Ar.

Published: March 2024

SR gas field is located the North Oman Salt Basin. The BK and MQ are the two main formations targeted for gas production. In most cases, these formations are clastic deep tight gas reservoirs that contain considerable hydrocarbon reserves but exhibit ultralow permeability. The poor connectivity between the pores may significantly reduce the recovery for economic gas production. The formations were initially developed with fractured vertical wells targeting up to 10 different hydrocarbon units. A similar approach was carried forward in highly deviated to horizontal wells targeting the tighter zones. However, the intrinsic geomechanical, petrophysical, and lithological heterogeneities of these tight units impact not only the fracture geometry and conductivity distribution but also the drainage efficiency of the fractured zones. This phenomenon manifests as variations in the units, thereby influencing their contributions to the commingled production, with the areas of higher mobility dominating the total gas production in the current well architectures.

A horizontal well designed to obtain the production from the tight zone experienced some challenges on the drilling and completion. To address the operational challenges drilling, logging, and completing horizontal wells in this field, the acquisition of cased-hole logging data to characterize the mechanical anisotropy with a through-the-bit sonic dipole sonic tool deployed via a tractor has emerged as a compelling logging solution. The logging-while-drilling sonic tool has limitations in measuring shear anisotropy, and using the sonic through-the-bit tool in open hole poses for getting stuck. In this case study, sonic data were recorded through casing with the latest-generation slim dipole sonic tool via e-coil across the horizontal section, the first in the world for this type of deployment. The dipole shear sonic tool is capable of recording shear anisotropy, which is used to determine key elastic properties to assess the hydraulic requirements for optimizing the efficiency of fracturing BK units across the horizontal section.

We present fundamental considerations for acquiring and evaluating rock mechanical formation anisotropy using through-the-bit dipole shear sonic tool inside tubing by an e-coil. This work uses methods to assess the dynamic variations of in-situ stress by using shear anisotropy and to determine the key elastic properties to identify the hydraulic requirements for fracturing individual units or a combination of them along the horizontal section. Included in the study are considerations of logging requirements, conveyance method, and sonic data processing and results as well as petrophysical evaluation and other reservoir criteria.

В настоящее время неоспоримой актуальностью обладает вопрос оптимизации процессов преподавания иностранных языков в российских высших учебных заведениях. В рамках данного исследования предпринимается попытка анализа когнитивно-лингвистического подхода как возможного инструмента для совершенствования языкового образования. Целью является разработка методологического арсенала на основе когнитивной лингвистики, позволяющего повысить эффективность учебного процесса. Рассматривая статистические данные, взятые из 23 российских вузов с общим числом студентов 48,323, и проводя эксперименты на выборке из 821 студента, данная статья стремится выявить критерии оптимальности и перспективы применения когнитивно-лингвистических методик. В синтезе основных исследовательских выводов следует подчеркнуть, что когнитивно-лингвистическая парадигма в контексте оптимизации методик преподавания иностранных языков в российской высшей образовательной системе выступает как комплексно структурированный объект научного анализа. Согласно проведенным статистическим анализам, в которых применялись методы дисперсионного анализа и регрессионного моделирования, выявлено, что студенты, обучающиеся по когнитивно-лингвистической методике, в среднем показывают повышение уровня владения языком на 14,7% в сравнении со стандартными подходами. Следует отметить, что эти результаты статистически значимы (p <0.05).

Currently, the issue of optimizing the processes of teaching foreign languages in Russian higher educational institutions is of indisputable relevance. Within the framework of this study, an attempt is made to analyze the cognitive-linguistic approach as a possible tool for improving language education. The aim is to develop a methodological arsenal based on cognitive linguistics, which makes it possible to increase the effectiveness of the educational process. Considering statistical data taken from 23 Russian universities with a total number of 48,323 students, and conducting experiments on a sample of 821 students, this article seeks to identify optimality criteria and prospects for the use of cognitive-linguistic techniques. In the synthesis of the main research conclusions, it should be emphasized that the cognitive-linguistic paradigm in the context of optimizing the methods of teaching foreign languages in the Russian higher education system acts as a complex structured object of scientific analysis. According to the conducted statistical analyses, in which the methods of variance analysis and regression modeling were used, it was revealed that students studying cognitive-linguistic methods, on average, show an increase in the level of language proficiency by 14.7% compared with standard approaches. It should be noted that these results are statistically significant (p <0.05).

В статье предпринята попытка теоретического обоснования и экспериментальной верификации системы обратного наставничества как важного фактора формирования и раскрытия личностного потенциала субъектов образования. Обратное наставничество рассмотрено как инструмент формирования и развития человеческого капитала, который, в свою очередь, выступает базовым системным явлением метапредметного характера и становится все более актуальным в современной педагогической системе. Доказывается, что наставничество не зависит от возраста, привычное наставничество от педагога к ученику не всегда остаётся эффективным и, следовательно, возможен совершенно иной путь разработки и реализации системы наставничества. Предлагается модель организации обратного наставничества по финансовой грамотности в вузе. Обоснованы этапы наставнической деятельности в практике преподавания финансовой грамотности. Подробно описаны этапы и результаты педагогического эксперимента. Проведенное исследование и эксперимент показали, что основные цели были достигнуты, участники эксперимента (наставники) не просто сформировали предметные, метапредметные компетенции, но и задумались серьезно о ближайшей педагогической деятельности в данной системе. У большого количества слушателей-участников референтной группы появился высокий мотивационный уровень к освоению дисциплины; навыки разновозрастного взаимодействия по вопросам финансовой грамотности; осознание себя в качестве будущего педагога, которому предстоит общаться в новой реальности.

The article attempts to theoretically substantiate and experimentally verify the system of reverse mentoring as an important factor in the formation and disclosure of the personal potential of the subjects of education. Reverse mentoring is considered as a tool for the formation and development of human capital, which, in turn, acts as a basic systemic phenomenon of a meta-subject nature and is becoming increasingly relevant in the modern pedagogical system. It is proved that mentoring does not depend on age, the usual mentoring from teacher to student does not always remain effective and, therefore, a completely different way of developing and implementing a mentoring system is possible. The model of organization of reverse mentoring on financial literacy at the university is proposed. The stages of mentoring activity in the practice of teaching financial literacy are substantiated. The stages and results of the pedagogical experiment are described in detail. The conducted research and experiment showed that the main goals were achieved, the participants of the experiment (mentors) not only formed subject, meta-subject competencies, but also thought seriously about the nearest pedagogical activity in this system. A large number of students-participants of the reference group had a high motivational level to master the discipline; skills of multi-age interaction on financial literacy; self-awareness as a future teacher who will have to communicate in a new reality.
Features of using iterative successive substitutions methods for calculating phase equilibrium with a capillary jump
Authors: Райковский М.И.
Published: March 2024

В статье представлены модификации методов последовательных приближений, которые используются для расчета фазового равновесия многокомпонентной термодинамической системы. В качестве примера рассмотрены два метода: метод последовательных приближений и метод квазиньютоновских последовательных приближений. Эти методы можно использовать для расчета равновесия между газовой и жидкой фазами со скачком капиллярного давления. Для проверки корректности методов результаты расчетов как фазового равновесия при заданных температуре и давлениях в фазах, так и фазовых диаграмм для различных температур сравнивались между собой. Получено малое расхождение в результатах при расчете фазового равновесия многокомпонентной смеси с учетом скачка капиллярного давления для летучей нефти.

This article presents modifications of Successive Substitution methods that are used to calculate the phase equilibrium of a multicomponent thermodynamic system. As an example, two methods are considered: the Successive Substitution method and the Quasi-Newton Successive Substitution method. These methods can be used to calculate the equilibrium between gas and liquid phases with a capillary pressure jump. To check the correctness of these methods, the results of calculations of both phase equilibrium at set temperature and pressures in the phases and phase diagrams for different temperatures were compared with each other. A low error in the results was obtained when calculating the phase equilibrium of a multicomponent mixture taking into account the capillary pressure jump for volatile oil.

Inspired by the process of water oxidation during photosynthesis, researchers have developed mononuclear and polynuclear transition metal complexes as homogeneous water oxidation catalysts. While water oxidation catalysis by mononuclear copper-peptide complexes with N4 motif has been briefly explored, there is limited research on how systematically changing individual components of the ligand framework can enhance water oxidation catalysis. We report the synthesis and characterization of a library of twenty-eight copper (II) peptide/peptidomimetic complexes, each incorporating a systematic ligand framework change. Their electrocatalytic water oxidation properties were investigated through cyclic voltammetry studies in a pH 11 buffer medium. These studies offer novel insight into how to enhance the water oxidation catalysis abilities of mononuclear and polynuclear copper-peptide/peptidomimetic complexes by modifying the ligand framework.
