Engage, Enthuse, Empower: A Framework for Promoting Self-Sufficiency in Athletes
Authors: Maloney Sean J.
Published: February 2023

The coach-athlete relationship is foundational to the success of the strength and conditioning (S&C) program. By better understanding and applying psychosocial principles, the S&C coach can augment their impact on performance. However, coaches should seek to look beyond just performance. This article aims to put forward the case for a novel philosophical coaching framework that emphasizes the development of autonomy and self-sufficiency in athletes. Autonomous, self-sufficient athletes are likely to be more resilient, perform to a higher level, and be better prepared for life after competitive sport. It is proposed that the “Three E's” are the foundational components of this novel framework. (a) Engage athletes by promoting active involvement, providing an appropriate challenge, and understanding their values. (b) Enthuse athletes by promoting positive affect, setting them up to experience success, and facilitating positive social interaction. (c) Empower athletes by promoting autonomy, periodizing self-government of their program, and providing the rationale to explain recommendations or prescriptions. The framework's objectives are to maximize athletes' internal drive, help athletes understand the basic principles of S&C, and encourage athletes to make positive behavioral choices.
Load Carriage for Emergency Responders
Authors: Orr Robin M. , Lockie Robert , Saari Anssi , Paavola Tommi , Muhlbauer Dagmar , Dawes Jay
Published: February 2023

Search and rescue (SAR) personnel may be required to wear and carry external loads during a task. These external loads may be carried in austere environments across unpredictable terrain. Like other tactical occupations (military, law enforcement, fire, and rescue), SAR loads can range from ≥20 to 45 kg. Not only are these loads known to cause a variety of injuries to the musculoskeletal, integumentary, and neurological systems of the carrier, but these loads are also known to impede task performance and have ultimately led to mission failure. Ensuring personnel are physically capable of carrying external loads on tasks is critical to mitigating these potential risks of injury and performance decrements. Optimal load carriage conditioning, following the known frequency, intensity, time, and type of training formula would see SAR personnel conduct a load carriage specific session every 7 to 14 days, with load weights, walking speeds, and durations akin to those typical of their SAR requirements. The terrain types (inclusive of grade and nature of terrain) should likewise form part of this conditioning process. In addition to load carriage-specific sessions, improving strength (notably relative strength) and aerobic fitness should also optimize the load carriage conditioning of SAR personnel.
Anaerobic Speed Reserve and Middle-Distance Performance: A Systematic Review
Authors: del Arco Asier , Martinez Aguirre-Betolaza Aitor , Castañeda-Babarro Arkaitz
Published: February 2023

Anaerobic speed reserve (ASR) allows us to measure an athlete's metabolic and neuromuscular capacities and to profile the different types of middle-distance runners. The main objective of this systematic review was to investigate the relationship between ASR and performance in middle-distance events. Five databases were consulted, and after the screening and selection process, 7 studies were selected. The results show that ASR has no relationship with performance. However, it may do so when one of its variables is equalized or considered as an interaction with its edges. Nonetheless, both maximal sprint speed and maximal aerobic speed influence performance in 800 and 1500 m, with major implications for pacing behavior or tactical decisions.
A Numerical Evaluation of Forming Failure of an Aluminum Sheet due to Splitting Damage in Hole Expansion Process
Authors: Aksen Toros Arda , Sener Bora , Firat Mehmet
Published: February 2023

The reduction of car body weight is the principal issue of car manufacturers for reducing fuel consumption. Aluminum alloys are attractive materials for the automotive industry because they have low density and adequate strength, but they may exhibit crack formation during manufacturing processes. Generally, crack formations emerge because of tool geometry and material anisotropy. Accordingly, determination of the forming limits of aluminum alloys is essential. The hole expansion test (HET) is a significant formability process used in the automotive industry because it gives information about the stretch-flangeability limits of the material. Edge splitting (edge fracture) is a failure type seen in HET, and it limits the stretch-flangeability of the material. Therefore, the prediction of edge splitting is an essential issue for engineers in the automotive industry. In this work, HET of AA6016-O aluminum alloy was simulated with the finite element (FE) method to assess the influence of yield functions on failure prediction in HET. To this end, Hill48, Yld91, and a homogeneous fourth-order polynomial type yield criteria (HomPol4) were selected to identify the anisotropic behavior of the sheet. Analyses were carried out in Marc commercial FE software, and the Hypela2 user subroutine was incorporated into FE code. Thickness distributions in the rolling direction (RD), diagonal direction, and transverse direction (TD) of the part and around the hole edge were also predicted, and it was observed that only the HomPol4 criterion predicted excessive thinning at two locations near the RD and TD, separately. On the other hand, Yld91 and Hill48 predicted lower strain levels when compared with HomPol4. Finally, plastic work distribution around the hole edge was considered, and the predictions were compared with the experimental damaged sample. This comparison showed that HomPol4 predicted a robust plastic work localization in RD, which is consistent with the damaged sample.
The CTLA‐4 immune checkpoint protein regulates PD‐L1:PD‐1 interaction via transendocytosis of its ligand CD80

Published: February 2023

CTLA‐4 and PD‐1 are key immune checkpoint receptors that are targeted in the treatment of cancer. A recently identified physical interaction between the respective ligands, CD80 and PD‐L1, has been shown to block PD‐L1/PD‐1 binding and to prevent PD‐L1 inhibitory functions. Since CTLA‐4 is known to capture and degrade its ligands via transendocytosis, we investigated the interplay between CD80 transendocytosis and CD80/PD‐L1 interaction. We find that transendocytosis of CD80 results in a time‐dependent recovery of PD‐L1 availability that correlates with CD80 removal. Moreover, CD80 transendocytosis is highly specific in that only CD80 is internalised, while its heterodimeric PD‐L1 partner remains on the plasma membrane of the antigen‐presenting cell (APC). CTLA‐4 interactions with CD80 do not appear to be inhibited by PD‐L1, but efficient removal of CD80 requires an intact CTLA‐4 cytoplasmic domain, distinguishing this process from more general trogocytosis and simple CTLA‐4 binding to CD80/PD‐L1 complexes. These data are consistent with CTLA‐4 acting as modulator of PD‐L1:PD‐1 interactions via control of CD80.
Theological and liturgical significance of troparia of the Beatitudes (Makarismoi) of the Holy Friday Matins
Authors:   Monaster Zwiastowania NMP w Supraślu, Polska, Karczewski Pantelejmon
Published: February 2023

On Good Friday matins, after singing the antiphons and before reading the canon, the verses of the Gospel blessings are read, which in liturgical practice begin with the words of the good thief: “Remember me, o Lord, in Your Kingdom”. The phrase of the thief hanging on the Cross sounds special on Good Friday – it is the day on which these words were spoken originally. Special troparions are added to the verses of the blessings, which talk about various aspects of Christ’s passion, mainly through the prism of the thief’s repentance. In the paper, the texts are analyzed taking into account the Greek original and selected translations.

Published: February 2023

The “Dictionary of Polish Orthodox terminology” contains an index of Greek equivalents in its structure. The process of selecting the Greek equivalents and assigning them to the appropriate Polish entries was difficult because of the number of Greek variants used in the Orthodox terminology, as well as the considerable amount of synonyms present in the Greek language, which is definitely the richest language in terms of history and theology. The article presents the role of semantic qualifiers in the process of selecting Greek equivalents, using selected examples of festive names.
Cerkiew Zwiastowania NMP w Supraślu i jej freski
Authors:   Uniwersytet w Białymstoku, Polska, Straczyński Karol
Published: February 2023

The Church of the Annunciation of the Blessed Virgin Mary in Suprasl is the example of a medieval, monumental defensive temple. In the first half of 16th century the decoration of the wall started, with wall paintings, in the style of the Orthodox Church. The Iconographic programme of the church was based on the symbolism and allegories from the Holy Bible. It also helped in the process of Christianisation of the society. It showed the content of the gospel, the hagiographies of saints and the activity of individual Church Fathers and bishops. The ornaments of the paintings separated the zones of imagination, decorated the panels formed by the vault and groin ribs and curled rows of medallions. Despite the destruction of World War II, several dozen fragments of polychromes have survived and have been reconstructed from the destroyed church.

Published: February 2023

This monograph is the result of the long standing morphological researches, as well as the theoretical generalizations based on them. The monograph discusses a number of issues regarding the origin and evolution of ontogenesis and phylogeny, the interconnectedness between individual and historical development of life forms. The manuscript consists of four chapters. Ontogenesis, mainly its prenatal period, is discussed in the first chapter. Well-known theories of the origin of life and the origin of embryogenesis are considered. Considerable amount of attention is given to the review of literature sources on the periods of chemical and biochemical evolution on the planet Earth, during which various chemical elements and their compounds came into existence, creating the “material base” for the formation of organic compounds, and later for the biologization of chemical components of the substances and cycles of energy flow, the emergence of mechanisms of self-organization and self-regulation, the heredity code and embryogenesis. The second chapter is dedicated to the discussion of the interaction of embryogenesis and phylogeny. The authors rethink the works of famous evolutionists and express some of their views on this issue. The authors’ own results regarding the embryogenesis of the cranium and skeleton of the limbs in individual representatives of different classes of vertebrates (mammals, birds, and reptiles) are presented in the third chapter. A comparative analysis of the results and literature data is conducted. The data on variation of some cranium structures in embryogenesis of investigated objects attract a lot of attention. The accumulation of such results is especially important to explain the origin of morphological adaptations, as well as evolutionary transformations and processes. The final chapter presents theoretical generalizations about the evolutionary significance of variation and variability. In particular, not just any variation, and not just any of its variants, carry the potential for the variability; not every variability leads to the macroevolutionary events. The authors touch on a wide range of general biological issues, generalize known theories, and sometimes express their own vision of the problem. This work may be of interest to a wide range of readers interested in embryology, morphology, and evolution.

Performance of AAP Clinical Practice Guideline for Febrile Infants at One Pediatric Hospital
Authors: Yaeger Jeffrey P. , Richfield Courtney , Schiller Emily , Oh Yubin , Pereira Beatriz M. C. , Shabangu Thandolwethu , Fiscella Kevin A.
Published: February 2023

BACKGROUND

In the absence of procalcitonin, the American Academy of Pediatrics’ clinical practice guideline (CPG) for evaluating and managing febrile infants recommends using previously untested combinations of inflammatory marker thresholds. Thus, CPG performance in detecting invasive bacterial infections (IBIs; bacteremia, bacterial meningitis) is poorly understood.

OBJECTIVE

To evaluate CPG performance without procalcitonin in detecting IBIs in well-appearing febrile infants 8 to 60 days old.

METHODS

For this cross-sectional, single-site study, we manually abstracted data for febrile infants using electronic health records from 2011 to 2018. We used CPG inclusion/exclusion criteria to identify eligible infants and stratified IBI risk with CPG inflammatory marker thresholds for temperature, absolute neutrophil count, and C-reactive protein. Because the CPG permits a wide array of interpretations, we performed 3 sensitivity analyses, modifying age and inflammatory marker thresholds. For each approach, we calculated area-under-the-receiver operating characteristic curve, sensitivity, and specificity in detecting IBIs.

RESULTS

For this study, 507 infants met the inclusion criteria. For the main analysis, we observed an area-under-the-receiver operating characteristic curve of 0.673 (95% confidence interval 0.652–0.694), sensitivity of 100% (66.4%–100%), and specificity of 34.5% (30.4%–38.9%). For the sensitivity analyses, sensitivities were all 100% and specificities ranged from 9% to 38%.

CONCLUSION

Findings suggest that the CPG is highly sensitive, minimizing missed IBIs, but specificity may be lower than previously reported. Future studies should prospectively investigate CPG performance in larger, multisite samples.
Artificial intelligence for materials research at extremes

Published: February 2023

Materials development is slow and expensive, taking decades from inception to fielding. For materials research at extremes, the situation is even more demanding, as the desired property combinations such as strength and oxidation resistance can have complex interactions. Here, we explore the role of AI and autonomous experimentation (AE) in the process of understanding and developing materials for extreme and coupled environments. AI is important in understanding materials under extremes due to the highly demanding and unique cases these environments represent. Materials are pushed to their limits in ways that, for example, equilibrium phase diagrams cannot describe. Often, multiple physical phenomena compete to determine the material response. Further, validation is often difficult or impossible. AI can help bridge these gaps, providing heuristic but valuable links between materials properties and performance under extreme conditions. We explore the potential advantages of AE along with decision strategies. In particular, we consider the problem of deciding between low-fidelity, inexpensive experiments and high-fidelity, expensive experiments. The cost of experiments is described in terms of the speed and throughput of automated experiments, contrasted with the human resources needed to execute manual experiments. We also consider the cost and benefits of modeling and simulation to further materials understanding, along with characterization of materials under extreme environments in the AE loop.

Graphical abstract

AI sequential decision-making methods for materials research: Active learning, which focuses on exploration by sampling uncertain regions, Bayesian and bandit optimization as well as reinforcement learning (RL), which trades off exploration of uncertain regions with exploitation of optimum function value. Bayesian and bandit optimization focus on finding the optimal value of the function at each step or cumulatively over the entire steps, respectively, whereas RL considers cumulative value of the labeling function, where the latter can change depending on the state of the system (blue, orange, or green).

Published: February 2023

Este artigo investiga o uso de plataformas digitais de mídias sociais pelos eleitores de Salvador, nas dez regiões administrativas da capital baiana, durante as eleições presidenciais brasileiras de 2018. Os dados foram levantados por meio de pesquisa domiciliar[1], com amostragem estratificada por sexo, idade e escolaridade e sorteio aleatório dos bairros, ruas e entrevistados. As cotas foram definidas e aplicadas com base nas estatísticas do eleitorado brasileiro, do Tribunal Superior Eleitoral (TSE), e na distribuição da população de Salvador prevista no último Plano Diretor de Desenvolvimento Urbano (PDDU). Os resultados da investigação comprovaram uma associação/correlação entre renda e escolaridade e participação política. As áreas que concentram populações com nível de vida mais alto registraram maior número de votantes usuários de mídias sociais que curtiram, comentaram e compartilharam conteúdos sobre política. Assim, o uso dessas ferramentas reproduziu as redes dominantes de poder da capital soteropolitana, com os mais abastados e mais escolarizados participando mais.[1] A pesquisa foi aplicada pelo Instituto PA - Pesquisa e Análise, um dos mais antigos de Salvador, a partir de questionário elaborado pela autora.

As oito expressões dos quatro tipos principais da teoria da expiação: as teo-logias da cruz em uma perspectiva metodista
Authors: Renders Helmut , Dos Santos Vilma Cavalcante
Published: February 2023

A partir do diálogo com a tipologia de teorias da expiação de Gustaf Aulén e com uma tipologia contemporânea com uma tendência menos confessional e mais complementar proponha-se um modelo de oito tipos clássicos. Paralelamente, investiga-se a sua presença nos textos de teólogos da tradição metodista desde John Wesley e entre teólogos do século 19 e 20. Conclua-se que entre os teólogos da tradição metodista há uma forte tendência no século 19 de seguir os modelos de Abelardo e Grotius, entendido como uma mediação entre Abelardo e Anselmo, pontualmente, Calvino e Anselmo. Esta tendencia é ainda reafirmada nos grandes dicionários metodistas das décadas 70 e 80 do século 20. A partir da década 90 anota-se uma maior diferenciação. Por um lado, mantenham-se as tradições; por outro lado anotam-se influências de Ireneu e Atanásio. Finalmente, retoma uma linha mais neo-ortodoxa a discussão sobre a validade dos modelos de Calvino e de Anselmo.
Kant e a Bíblia: fundamento e princípios de uma hermenêutica crítica
Authors: Freire Francisco das Chagas de Oliveira
Published: February 2023

A expressão “teologia kantiana” é considerada um oximoro para numerosos intérpretes. No entanto, a teologia e a religião têm lugar central no sistema kantiano e o cristianismo é reconhecido como a única fé racional. Este artigo visa a delinear o fundamento e os princípios hermenêuticos da teologia bíblica no corpus kantiano. A teologia kantiana radica-se na racionalidade prático-teleológica, enraizada numa necessidade moral inabdicável. A teologia é uma disciplina autônoma, regida pelos princípios do pensamento, entendido por oposição a conhecimento. Os princípios exegéticos de Kant sugerem uma revolução que visa a resgatar a plena harmonia entre fé e razão, posta em questão pela revolução científica e consolidada pela imagem mecanicista do mundo, que tendia a reduzir a fé à irracionalidade.

Published: February 2023

In this work, a study was made of the pollution of water bodies by enterprises of the Moscow region. Much attention is paid to the issues of pollution of water bodies by both Russian and foreign scientists. New technologies for water purification from pollution are being developed. I use new methods and approaches in research and study of this issue at various levels and localizations. The article clarified the general principles for determining pollutants in water bodies from the enterprises of the Moscow region, as well as the permissible and actual concentrations of pollutants. The authors studied archival materials of hydrological and engineering-geological surveys, as well as analyzed the scientific literature. As a result of the study, we found that storm drains from the enterprise pollute the soil not only of the enterprises, but also of the surrounding territories. These studies are confirmed by the works and can serve as indicators for assessing the sustainability of the natural complex of the territory of small towns in the Moscow region. Also, calculations were made of the maximum allowable discharge, which is the product of the volume of surface runoff coming from the territory of the enterprise and the permissible concentration of harmful substances contained in the wastewater discharged by the enterprise. Based on the study, it is necessary to carry out an action plan to achieve the maximum permissible discharge, such as: collection, as well as timely removal of household waste from the territory of an industrial enterprise during the year in order to reduce the concentration of wastewater, as well as measures that exclude the possibility of spilling oil products during transportation cargo throughout the year.
EFFECT OF NON-UNIFORMLY DISTRIBUTED POROSITY OF GAS DIFFUSION LAYERS ON MASS TRANSFER IN PROTON EXCHANGE MEMBRANE FUEL CELLS
Authors: Yu Rui Jiao , Guo Hang , Ye Fang
Published: February 2023

Gas diffusion layer porosity can affect mass and charge transfer inside proton exchange membrane fuel cells and influence cell performance. Moreover, the electrochemical reaction rate distribution in various regions inside the cell is not uniform. Proper porosity distribution is very important to improve cell performance. In this paper, a three-dimensional fuel cell model with three steps porosity along the gas flow direction is established. Four cases of non-uniformly distributed porosity, both in anode and cathode gas diffusion layers are simulated, which are compared with uniform porosity distribution to study the effect of these structures on mass transfer inside the cell. Then, an optimization calculation is carried out to obtain the optimal porosity distribution along gas flow direction at 0.2 V and 0.6 V. The numerical results indicate that non-uniformly distributed porosity can change cell performance, and porosity increasing along the gas flow direction makes cell performance be better. Porosity increasing along the gas flow direction can improve the uniformity of current density distribution at low voltage. Diffusive mass flux plays a dominant role in reactant mass transfer. Higher porosity near the outlet region increases total mass flux at the interface, and the proportion of diffusion mass flux in total mass flux also increases.

Published: February 2023

One of the most widely studied branches of biologically induced mineralization (BIM) processes, microbially induced calcium carbonate precipitation, also known as microbially induced calcite precipitation, can be used as a method for the reinterpretation of waste natural stone particles into a sustainable material. By overcoming the need for synthetic adhesives or energy-consuming firing or sintering procedures for regaining such wastes, a natural and sustainable solution is proposed through certain biological treatment processes. The aim of this study was to determine the main processing variables affecting microbially induced biocement production using waste stone as a scaffold material. Bacillus pasteurii bacteria were used for biological induction of calcite precipitation. A custom-made reactor was designed for controlled incubation and medium injection into the waste stone scaffold. The parameters examined were the particle size of the waste stones, the effect of the stone type on cementation, the urease activity of the bacterial culture, temperature, the pH and flow rate of media, the mechanical strength of cemented scaffolds and water absorption capacity. This research demonstrated a potential solution to the waste generation problem of the global natural stone industry through the treatment of such wastes with BIM for creating a sustainable and biogenic material.

Published: February 2023

This study investigated the relative effects of tribological process parameters and their optimization for wear responses of a TiAlN thin film deposited on heat-treated and plasma-nitrided novel MDC-K hot work tool steel. The effects of tribological process parameters were studied by conducting a tribological test on the TiAlN thin film against a tungsten carbide (WC) counterbody. The researchers considered three tribological process parameters – namely, sliding velocity, applied load and sliding distance – to conduct the tribological test and study the effect of the parameters on five different wear responses – namely, friction coefficient, surface roughness (R a), wear depth, wear mass loss and hardness. The relative effects of the process parameters were studied using contour plots, and the individual effects and contributions were analyzed using an analysis of variance test. Further, the overall evaluation criteria method was employed to select the optimal settings of tribological process parameters based on the experimental results. Finally, the surface morphology of the worn TiAlN surface against the best and worst parametric settings was evaluated using scanning electron microscopy integrated with energy-dispersive X-ray spectroscopy to investigate the underlying wear mechanisms.

Published: February 2023

Desde hace más de una década, el currículum de Educación Primaria pone más énfasis en el cálculo mental que en el cálculo escrito, aunque en la práctica docente se siga priorizando la enseñanza de algoritmos escritos verticales. En este sentido, la enseñanza y aprendizaje de estos algoritmos sigue generando ciertas dificultades en parte del alumnado. Esto hace que en los centros educativos se estén implementando alternativas al cálculo escrito tradicional,con el objetivo de incentivar el desarrollo de estrategias cognitivas de cálculo mental y mejorar la competencia matemática del alumnado. El presente estudio tiene como finalidad analizar las posibles diferencias en cálculo escrito y cálculo mental en último ciclo de Educación Primaria, comparando alumnos que siguen dos metodologías distintas de aprendizaje de las matemáticas, como son el método Abierto Basado en Números (ABN) y el método Cerrado Basado en Cifras (CBC). Actualmente, está en ejecución un estudio empírico que cuenta con una muestra de 245 participantes, 106 pertenecientes al grupo experimental (ABN) y 139 al grupo control (CBC). Los instrumentos de evaluación empleados en este estudio fueron distintas pruebas de resolución aritmética. El grupo experimental mostró un rendimiento superior en la variable cálculo mental (XGC = 9.18; XGE= 13.21), siendo significativas las diferencias entre los grupos (p < .001). Por el contrario, el grupo control mostró puntuaciones superiores en cálculo escrito frente al grupo experimental (XGC = 16.71; XGE =15.38), siendo de nuevo significativas estas diferencias (p < .001). Estos resultados sugieren profundizar en las estrategias cognitivas de cálculo mental utilizadas por el alumnado y su posible influencia en el rendimiento matemático y en otras áreas del currículum de Educación Primaria.
Axiology of neophrasemes and phraseotransformations in lexicographic interpretation

Published: February 2023

The article presents the authors’ solution to the problem of dictionary description of neophrasemes and transformed phraseological units. The aim of the article is to show the axiology of phraseological neologisms in its dynamics and to reveal the possibilities of lexicographic interpretation of the evaluative vector of new and transformed phraseological units. The lexicographic experience accumulated by the authors in this direction is summarized. The models of axiological parameterization of phraseological neologisms developed for the updated versions of phraseological and slang dictionaries using the method of structural-semantic modeling, contextual, historical-etymological and linguoculturological analysis are shown on the phraseological material of the last three decades. The research revealed trends in updating the phraseology of the national language and its social variants. The sources of new axiological phraseological units in the field of literature, cinema, political discourse, and advertising are considered. The axiological semantics of neo-phrasemes borrowed from the English language, reflecting new facts and trends in the sociopolitical and economic spheres, is determined. The results of the study have led to conclusions about the optimal ways of representing the axiological semantics of neophrasemes, developed in addition to the materials of the Large Dictionary of Russian Sayings, the Large Dictionary of Russian Jargon, and the special dictionary of new Russian phraseology: for this purpose, not only traditional “stylistic” marks can be used, but also evaluatively oriented definitions and comments that reveal the motives of naming and chronotopic labeling of neophrasemes. As illustrations, in addition to text fragments, Internet memes that explicate the meaning of phraseological neologisms will be useful. The expediency of creating a special dictionary of phraseotransforms, in most cases implementing the function of evaluating objects and phenomena in socially significant areas, is proved. An algorithm for describing phraseotrans-forms in a complex dictionary entry under the heading in the form of a phraseological unit in canonical form is presented. This will make it possible to trace the evaluative constants of linguaculture and the reorientation of the axiological vector and the function of the phraseological unit, which in the act of transformation loses its negative evaluativeness, turns into a hashtag, a fragment of an email address or is remotivated and becomes a visual phraseo-joke in the format of an Internet meme. The results of the study will be useful for the development of the theory of linguoaxiology and phraseographic practice. The authors declare no conflicts of interests.
The inner world of a person in metaphorical models with the object domain “precious stones” (based on dictionaries of poetic images)
Authors:   University of Tyumen, Kupchik Elena V.
Published: February 2023

The article characterizes the inner world of a person in metaphorical models with the object domain “precious stones” in dictionaries of images. The research material is fragments of texts of Russian literature, including figurative comparisons of the realities of the inner world of a person with precious stones. Sources of the material are: Dictionary of Poetic Images by N.V. Pavlovich; Dictionary of the Language of Poetry by N.N. Ivanova and O.E. Ivanova; Materials for the Dictionary of Metaphors and Comparisons of Russian Literature of the 19th-20th Centuries by N.A. Kozhevnikova and Z.Yu. Petrova. The article uses the following research methods and techniques: analysis of theoretical sources on the problem, collection of material, observation, classification and systematization, quantitative calculations. The research includes the following stages: detection in dictionary materials of the realization of metaphorical models containing a comparison of an object of the inner world with the object domain “precious stones”; determination of the composition of the models; description of the subject and object areas; determination of the grounds for comparisons; identification of the most significant subjects and objects of comparison and the main metaphorical models; indication of trends in the development of imagery reflected in the implementation of metaphorical models in texts of different times. The study shows that dictionaries of images contain a significant number of implementations of metaphorical models of the inner person with the “precious stone” object domain. These models capture ideas about features and properties of the realities of the inner world important for Russian culture, relating to the invisible organs of a person, their feelings, emotions, intelligence. The main subjects of comparison are soul, heart, love, sadness, dream, thought; the main objects of comparison are diamond, pearl and rhinestone. These comparisons are much more common than others and are reflected in all three dictionaries. The hardness, transparency, brilliance of a cut diamond; the color and purity of pearls; the transparency and fragility of crystal, its ability to sound allow them to be metaphorical analogues for especially valuable and attractive realities of the inner world of a person. The figurative characteristic of the inner world is also based on the peculiarities of the formation of diamond (earth’s interior, pressure, high temperatures) and pearls (water depths, closeness in the shell). The materials of the dictionaries reflect the trends in the development imagery; the replenishment of figurative series with new elements, the reduction of traditionally elevated realities, the concretization of images. The implementation of metaphorical models with the object domain “precious stones” reflect in versatile ways the ideas about the inner world of a person that exist in Russian culture.

Systematic Literature Review of Conversational Code-Switching in Multilingual Society From a Sociolinguistic Perspective
Authors: Zhong Xinyi , Ang Lay Hoon , Sharmini Sharon
Published: February 2023

Code-switching (CS) is widely used across the globe despite the unclear research trends and gaps in CS studies due to under-researched reviews on it. The current study is a systematic literature review (SLR) of conversational CS from a sociolinguistic perspective from 2010 to 2022 using the PRISMA 2020 framework. Keywords query was performed at Oct 31, 2022 on Scopus and Web of Science databases. As a result, a total of 117 articles were included for further analysis. It is found that the number of CS studies was continuously increasing before encountering declines from 2019. Previously, scholars preferred empirical studies, qualitative designs, and data collection methods including discourse analysis, observation, interview and questionnaire. Regarding research objectives, a majority of studies examined the factor of CS, mainly from the micro levels. Besides that, many studies had explored attitude and identity towards CS in the past five years. As for research contexts, Asia became the research centre of previous CS studies. However, there was a lack of CS studies worldwide, especially among Oceania, South America and Africa. Multilingual societies in the Expanding Circle require more discussion.
Role of bone marrow-derived mesenchymal stem cells in treatment avascular necrosis of femoral head
Authors: Yousif nasser
Published: February 2023

Avascular necrosis (AVN) of the femoral head (FH) is a debilitating and painful disease with multiple etiologic risk factors head shows an increasing tendency and most commonly affects younger or middle-aged adults. Fifty patients (55 hips) with stage I, II or III avascular necrosis of femoral head were treated by autologous Bone marrow-derived mesenchymal stem cells injection. The patients were followed up clinically and radiologically for a minimum of 2 years at baseline, three, six, 12, and 24 months. The functional outcome was assessed in terms of Harris hip score, and disease progression was assessed radiologically by comparing the preoperative and follow-up MRI at the end of 2 years. On 2-year follow-up, there was considerable improvement in the hip function as measured by the Harris hip score (p = 0.041). On MRI, there was a decrease in the size of the lesion in group A (p = 0.03). Our findings showed that autologous Bone marrow-derived mesenchymal stem cells in avascular necrosis of femoral head is a safe and effective procedure and has better outcome.
Análise Espacial e Temporal do Uso e Ocupação da Terra Associado a Atividade de Extração Mineral no Rio Jequitinhonha Diamantina - MG

As ferramentas de sensoriamento remoto estão cada vez mais presentes em estudos ambientais. As principais razões são sua praticidade, baixo custo e rápida resposta para análises preliminares. Desde o lançamento do primeiro satélite da série Landsat, estudos de análise temporal se tornaram importante recurso para entender as alterações na superfície da terra, as quais podem ocorrer de formas naturais ou por intervenções antrópicas. Essas mudanças podem acontecer de modo pouco perceptível durante curtos períodos de tempo, e muitas vezes, são evidenciadas ao analisar períodos de longa duração. O presente estudo tem como objetivo compreender como ocorreu a evolução do impacto ambiental, durante um período de 40 anos, em uma área afetada pela atividade de extração mineral, e as mudanças causadas na morfologia do rio Jequitinhonha-MG. Para tal, foram utilizadas imagens Landsat 5 e 8 e o cruzamento de suas bandas espectrais para a criação de imagens NDVI, em áreas de lavra de ouro e diamantes, ocupadas pela atividade do garimpo, localizados em um segmento fluvial do rio Jequitinhonha, próximo ao município de Diamantina, Minas Gerais .Este estudo contribuiu para a identificação dos estilos e feições fluviais, apontando alterações no quadro evolutivo e dinâmico nos padrões de drenagem e no aporte sedimentológico. Identificou-se que o uso e ocupação da terra fundamentam-se como a principal causa dessas alterações morfológicas ao logo do tempo.
Do narrar a si à revelação do ser docente: por entre dizeres de licenciandos de geografia em formação
Authors: Menezes Victória Sabbado , Costella Roselane Zordan
Published: February 2023

O artigo em tela tem o intuito de provocar reflexões concernentes à constituição do ser professor de Geografia a partir da perspectiva (auto)biográfica. Esta compreende a formação docente enquanto um processo que se desenvolve ao longo da trajetória de vida do sujeito. Assim, são analisadas narrativas (auto)biográficas de cinco licenciandos em Geografia de uma universidade federal do interior do Estado do Rio Grande do Sul que foram produzidas durante a realização do Estágio Supervisionado em Ensino Fundamental dos mesmos. O olhar analítico busca fundamentação no referencial teórico pertinente ao ensino de Geografia, formação de professores e pesquisa (auto)biográfica. Por meio das narrativas (auto)biográficas dos acadêmicos foi possível identificar as relações existentes entre os percursos de vida pessoal e de escolarização, explicitados pela evocação de memórias, com sua projeção profissional. Depreende-se que a escolha pela profissão, pela área de ensino, as concepções de docência e de Geografia imprimem as marcas de uma trajetória de vida que é única e singular. Logo, a constituição do ser docente é inerente ao processo existencial do professor. Isto posto, as narrativas (auto)biográficas revelam que esta concepção de formação é profícua e interessante de ser adotada no contexto da licenciatura a fim de que o (futuro) professor de Geografia se assuma como sujeito de sua formação pela apropriação de seu percurso de vida.
