The study came into the background by the many students who had difficulty learning geometry in particular. The purpose of the study to describe the process of eighth graders' thinking in resolving a fourth matter. The type of research used is a qualitative approach. The data-gathering method used is tests and interviews. The subject of this study is two visualization level students, two analytic levels, and one informal deduction student. The result is that students of the visualize level are often quelled to settle the matter at a level of four, but when given a student's explanation can adjust, resulting in an equilibrium. Students' level analysis has been quizzing when seeking a consensus solution, but after accommodations are underway, students can understand the problem by equilibrium. The students of the informal deduction level have not been quizzed to complete the fourth matter, so the information gained is assimilated and equilibrium.
Andrei Platonov’s writing method: selected key characteristics and linguostylistic means
Authors: Bouilov Vassili V.
Published: December 2021

Andrei Platonov’s writing method in its ideological and theoretical basis is considered by us as the ontological relationship of his personality and creative perspective with spiritual values, attitudes and philosophical views which he professes. This writing method is realized in Platonov’s prose through the artistic interaction of author’s philosophical concepts and linguistic means which form his idiostyle. The main and broader goal of our research is a systematized and classifying description of the key language models and techniques most typical of Platonov’s writing method. The scientific results of our comprehensive analysis of Platonov’s idiostyle testify to our assertion that most of the elements and features of Platonov’s “deformed” and “coded” language are artistically modeled and are an example of the author’s successful stylization. Due to the peculiarities of the author’s language and style, Platonov’s literary text is distinguished by rich semantic ambivalence and implicativity. The volume of our work does not allow us to present a more detailed presentation of the provisions of Andrei Platonov’s creative method and an all-encompassing analysis of the most important linguostylistic means which make up it. In this we, we set our specific task within the framework of a brief analytical review of the individual charac-teristics of Platonov’s writing method and a selective linguostylistic analysis of the key and most effective means and techniques of linguistic expressiveness which form this unique author’s me-thod, to clearly demonstrate some of its fundamental principles and approaches.
Aesthetic component of nicknames of Russian servicemen
Authors: Rodina Nadezhda A.
Published: December 2021

We consider nicknames in the environment of modern Russian servicemen identify their aesthetic potential and features of their use in speech communication. Based on the answers to the questions of anonymous questionnaires filled out by Russian servicemen of various age groups, we establish that the nomination of nicknames for naming and naming contains various types of assessment, including emotional, which is manifested in the binary oppositions “good – bad”, “positive – negative”, ”beautiful – ugly”. We reveal that individual nicknames among modern Russian servicemen reflect an aesthetic function and are used only by those who are equal to its bearer. Communicators tend to label aesthetically positive characteristics in nicknames. Units from various layers of the national language (literary, colloquial, slang vocabulary) are involved in informal communication. We prove that the same nicknames do not arise among the military, even if the motivation is the same (tall – Long, hair color – Red). In the process of verbal communication, a linguistic personality with the help of a nickname demonstrates the national-cultural specificity of a representative of the society and the national-cultural specificity of the communication situation itself.
Water as a linguocultural constant of A. Platonov’s creativity: an onomastic aspect (based on the story “The Sluices of Epifany”)
Authors: Bugakova Nadezhda B.
Published: December 2021

We analyze the features of onomastic units functioning, which are cultural-onomastic constants, in the A. Platonov’s story “The Sluices of Epifany”. We substantiate the special attention that is drawn to the specificity of the introduction by the author of onomastic units of different categories. We show that a proper name is a special artistic element that does not exist indepen-dently in the text and is always interconnected with other elements of the text, since it is necessary for the author to create an artistic image. An interaction analysis of all these systems makes it possible to more accurately understand the author’s intention and the purpose of introducing one or another onomastic unit into the text. We reveal the features of onymic vocabulary functioning as an identifier of the chronotope in A. Platonov’s story “The Sluices of Epifany”. It is obvious that the introduction by the author of specific onomastic units into a work is always not accidental, such a choice is always caused directly by the author’s associations related to a particular name. The analysis of the author’s use of hydronyms as onomastic units as chronotope markers in the story “The Sluices of Epifany” gives the following results: by the means of hydronyms denoting the names of rivers and seas, A. Platonov verbalizes the scale of the described space, emphasizes its limitlessness; introducing the hydronym Ivan-lake into the text, the author verbalizes the chronotope of abyss. We conclude that space as a category in A. Platonov’s picture of the world occupies an important place.
Y.V. Trifonov’s novel “The Impatient Ones” in the context of the social and political position of I.А. Dedkova
Authors: Zaytsev Aleksandr V.
Published: December 2021

We tell about the I.A. Dedkov’s views on the ratio of end and means on the way to high social ideal. We conduct an analysis that reveals the humanistic ontology of his worldview. Being a staunch antistalinist, supporter of the decisions of the 20th Congress of the CPSU, I.A. Dedkov throughout his life and work, in letters, diary entries, in literary-critical and practical activities, consistently condemned the inhuman principle “the end justifies the means”, drawing for this ar-guments from the traditions of Russian classical literature and Russian pre-revolutionary liberal-oriented philosophy, as well as from Western European existentialism. We reveal this humanistic and ideological intention that existed latently in the times of the USSR in the literary heritage of the critic and journalist I.A. Dedkov. The main methods used in the preparation of this work: ele-ments of systemic and comparative analyzes, biographical, discursive and narrative research me-thods. The main conclusions from the study are the disclosure of the humanistic nature of I.A. Dedkov, which sharply differs from the immoral methodology of political expediency, neg-lecting the choice and use of ethically grounded and adequate means of its implementation. This provision is supported by texthestruic analysis of a number of sources, including the Y.V. Triforov’s novel “The Impatient Ones” from the series «Family Revolutionary» on the revo-lutionary population of A.I. Zhelyabov. I.A. Dedkov consistently defended his theoretical and ideological postulates based on the non-acceptance and rejection of inhumane and ruthless politi-cal practices in his literary, critical and journalistic activities, as well as in his personal life, while remaining loyal to the socialist (communist) ideal in its humanistic (anthropocentric) ideal.

Published: December 2021

Transfer phenomena between Portuguese (L1) and English (L2) produced by Brazilian learners are well documented in the literature. However, the identification and classification of these processes are made mainly through transcriptions, a slow and laborious process done by specialized linguists. The rapid identification of these phenomena would be of great value for software doing proficiency placement tests and could be used in language schools, distance education, computer-assisted pronunciation training (CAPT) or by autodidacts and researchers. The present work analyzed possible techniques and tools that can be used in the automatic identification of some transfer processes. The data for the grapho-phonic-phonological transfer were synthetically generated in the Google Translate™ TTS system. Then we tested three classification algorithms to perform the identification: k-Nearest Neighbor, Centroid Minimum Distance, and Artificial Neural Networks. The results indicate that these techniques are of great value for Linguistics and for new software applications in language learning.

JOHN LOCKE EPİSTEMOLOJİSİNDE DOĞRULUK KAVRAMI
Authors: ÇELEBİ Emin
Published: December 2021

17. yüzyılın önemli düşünürlerinden olan J. Locke, dönemin epistemolojik paradigmasının oluşumunda önemli bir rol ifa etmiştir. Felsefi görüşleriyle kendisinden sonraki dönemleri de etkileyen filozof, özellikle Aydınlanma düşüncesinin kilometre taşlarından biri olarak kabul edilebilir. Epistemolojisini bütünüyle deney üzerine inşa etme iddiasında olan filozofun, bu iddiasını ne denli tutarlı bir biçimde gerçekleştirdiği tartışmaya açıktır. Bununla beraber epistemolojisini kurgularken yaptığı birçok çözümlemenin çağdaş epistemolojilerde karşılık bulan bir mahiyette olduğunu söyleyebiliriz. Epistemolojik doğruluk meselesi de bunlardan biridir. Bu çalışmada Locke’un doğruluk görüşü, epistemolojisi bağlamında tartışmaya konu edilecek ve ancak kısmi bir doğruluk ortaya koyabildiği ileri sürülecektir. Bunun ise filozofun “bütün bilgilerimizin basit idelerden oluştuğu” biçimindeki tümel ve tikeli tazammun eden kabulünden kaynaklandığı iddia edilecektir.
ENSURING THE STABILITY OF INTERNAL DUMPS ACCORDING TO THE RESULTS OF PHYSICAL AND MECHANICAL PARAMETERS OF SOILS
Authors: Stovpnyk Stanislav , Kosenko Tetiana
Published: December 2021

Purpose. The paper considers the issues of ensuring the stability of internal dumps consisting of soft rocks. This issue is relevant because the stability of quarry boards and dumps affects the safety of work in quarries. Methodology. When assessing the stability of slopes, the method of determining the minimum coefficient of stability, equal to the ratio of restraining forces to shear forces that arise in the slope array.

Findings. The calculation and assessment of the stability of the slopes of the dumps are carried out on the example of Malyshevsky rutile-zircon-ilmenite deposit. The geological structure of the deposit overburden is represented by loess-like loams, red-brown clays, gray-green clays, fine-grained sands. To ensure the stability of internal dumps, the selective formation of dumps is proposed, which is presented in this paper in two ways. In the first variant, the dumping of Sarmatian gray-green clays into the lower part of the heap, which are weakly permeable and have low strength, is considered. In the second variant, a layer of Sarmatian sands is poured into the base of the dump. According to the normative value of the coefficient of stability margin, depending on the physical and mechanical properties of the rocks that make up the array, the optimal height and slope angle of the dump are determined. When assessing the stability of the slopes of the dump, the impact of groundwater and the possibility of location in the developed space of the tailings were also taken into account.

Originality and Practical implications. Studies have shown that the most rational option is the formation of internal heaps with embedding in the base of the lower tier of the heap with a height of 40 m layer of Sarmatian sands; in the case of embedding in the lower part of the inner heaps of gray-green clays, it is advisable to form the lower tier of the heap with 2 sub-tiers up to 20 m high; the upper tier of the dump is recommended to be formed by one massif 26 m high. Besides, in the produced space of the quarry, the location of the tailings is possible in case of dumping Sarmatian sands into the base of the dump.

The indicator of the coefficient of safety of the stability of the corresponding deviation after its formation and building, which means that it exceeds the minimum, in accordance with current regulations (n=1,329>1,3), after it is formation with further use joint dumping of overburden rocks and enrichment wastes is possible and appropriate.
CHANGE OF ENERGY CHARACTERISTICS OF LITHOSPHERE ELEMENTS DURING THEIR DEFORMATION
Authors: Kryuchkov Anatolii , Bakhtyn Anatolii
Published: December 2021

Purpose. The purpose of this study is to establish analytical patterns for predicting changes in stress and energy density spent on the destruction of rocks according to experimental studies. To solve this purpose in the article were set the following scientific problems: 1) analytical description of the dependence of the stress σij on the main deformation εij; 2) establishment of calculation parameters that are included in the analytical patterns; 3) analytical description and study of fracture energy density curves.

Methodology. In the course of analytical and experimental researches of full diagrams of deformation of rocks the mathematical model of dependence of the stress on the deformation is developed. Physico-mechanical processes of all characteristic sections of the complete deformation diagram were also analyzed and described. Analysis of the resulting curve showed that the rock mass and elements of the lithosphere are not perfectly elastic or plastic objects. Along with the elastic ones, plastic ones are always present to one degree or another.

The integration of the obtained analytical expression σ11 = f(ε11) allowed to establish the volumetric energy density spent on the destruction of the rock sample under the action of external load. The maximum activation energy for the considered rock is 0.67 MJ/m3. A comparison of the experimental and calculated values of the energy dependence u(ε1) shows a coincidence over almost the entire range of deformation changes (ε11 = 0..0.04).

Findings. The study of rock samples at hard stress allowed to obtain a complete deformation characteristics of the rock. The curve that surrounds the deformation cycles (1) combines pre-boundary, boundary, extremal modes of deformation and destruction of rocks. Equation (4) allows us to establish that the destruction can occur at different values of energy density U(ε).

Originality. An analytical description of the energy diagram of deformation and a complete diagram of stress change in the form of a single dependence, which takes into account the boundary and extremal areas, was developed in the work. In contrast to the method of piecewise linear approximation, this approach corresponds to the physics of the process and reduces errors in calculations.

Practical implications. Theoretical and experimental analysis of the obtained energy fracture diagrams and complete stress change diagrams in rocks allows to estimate the bearing capacity of a rock mass or other solid body. This allows you to predict critical values of stresses and external loads to prevent failure in a timely manner.
A LIBERDADE DE EXPRESSÃO NO ÂMBITO JORNALÍSTICO: A CENSURA COMO ULTIMA RATIO À LUZ DO ORDENAMENTO JURÍDICO BRASILEIRO
Authors: de Sousa João Pedro Martins , Do Amaral Liana Silva
Published: December 2021

É inquestionável a importância da conservação da liberdade de expressão, direito fundamental assegurado veementemente pelo ordenamento jurídico brasileiro, compreendendo-se aqui a Constituição da República, a Convenção Americana de Direitos Humanos e leis especiais, haja vista a íntima relação existente entre a liberdade de expressão e o regime democrático. A justificativa deste trabalho reside no fato de que, apesar de firmemente assegurado em normas positivas, a liberdade de expressão encontra vários óbices a sua consolidação na mentalidade sociojurídica pátria, a qual, preservando uma herança execrável de tempos sombrios para as liberdades públicas, continua a enxergar a censura como único meio existente para combater eventuais excessos decorrentes do exercício desse direito fundamental. À vista disso, tem-se como objetivo realizar uma análise histórica e jurídica a respeito da liberdade de expressão, com ênfase na liberdade de imprensa e liberdade de informação, diante dos parâmetros fixados na Reclamação n° 22.328/RJ, de relatoria do Ministro Luís Roberto Barroso, traçando fundamentos para que a censura, entendida como limitação extrema da liberdade de expressão, seja efetivamente alçada a ultima ratio no Direito brasileiro, abrindo-se espaço para que medidas alternativas sejam acolhidas pelo Poder Judiciário para concretizar a ponderação de interesses. Utilizou-se o método dedutivo de pesquisa, valendo-se da análise literária, jurisprudencial e legal para investigar como essas medidas alternativas possuem o condão de equacionar tanto a liberdade de expressão quanto o direito personalíssimo atingido, promovendo a ponderação e a harmonização, ao mesmo tempo convertendo a censura como último recurso a ser utilizado no caso concreto.
Microbiomarkers of the local environment and interior of Neolithic and Eneolithic dwellings (settlements of Mergen 6 and 7)

Published: December 2021

The paper concerns the analysis of the local environment around the multi-layer settlements of Mergen 6 and 7 situated in the immediate vicinity of each other. The settlements existed successively (partly contempora-neously in the early and high Neolithic) in the forest-steppe belt of Western Siberia. Two methods were chosen to obtain the results: spore-and-pollen (palynological) and microbiomorphic analyses of the cultural layers of the settlements of Mergen 6 and Mergen 7. In the settlement of Mergen 6, the following samples were collected for the palynological and microbiomorphic investigation: a vertical column from the center of the ditch of the dwelling no.5; areal soil samples of the dwelling no.5 from underneath the pottery debris of the Neolithic and Eneolithic periods; areal samples from the bottom layer of the dwelling no.21. In the settlement of Mergen 7, two vertical core samples were selected for the pore-and-pollen analysis: in the ditch of the dwelling no.1; and in the inter-dwelling area. Samples from the hearthing of the dwellings and from the inter-dwelling space were collected for the microbiomorphic analysis. The obtained results show that both settlements existed during the forest-steppe conditions, although the original landscapes of the sites chosen by the people for building the settlements were different in the early and high Neolithic. It appears that during the early Neolithic, the settlement of Mergen 6 was associated with an open site with meadow-steppe vegetation; birch forests constituted a small part of the land-scape, whilst there were no pine forests in the close vicinity. During the middle Neolithic, people in the settlement of Mergen 7 preferred to settle in a birch wood, having cleared out a small area to build the dwelling. The results of the microbiomorphic analysis show that, despite the lack of pine forests nearby the settlements, people still used pine tim-ber in housebuilding, apparently, intentionally. The frequent occurrence of remains of the wood detritus at the level of the floor of the dwellings and under pottery supports the initial archaeological observations about timber decking inside the houses. However, pollen and phytolithic studies do not demonstrate a wide use of the wetland waterside vegetation in housebuilding, apparently, because the lake at the time was not overgrown on the banks by reed and cattail. There-fore, despite the close location of the two sites and their similar hunting-fishing specialization of the subsistences, their populations in different chronological periods preferred distinct local conditions.
Women’s Hairstyles and Head Ornamentation of the Yakuts in the 18th century
Authors: Prokopeva A.N.
Published: December 2021

Mass Christianization of the peoples of Yakutia (Eastern Siberia) at the end of the 18th century led to the development of a demotic Christianity throughout the 19th century. There were new rules, according to which a woman was not permitted to appear in public with her head uncovered, and therefore the marking function of the hairstyles became obsolete. This could explain the absence of rituals and rules associated with women’s hair and hairstyles in the Yakut culture of the 19th–20th centuries. The aim of this study is to prove a hypothesis, according to which pendants of hair ornamentation duplicate braids, and studying the pendants of the headrest ‘nachel’nik’ allows recreation of women’s hairstyle that had been in use before the period of mass Christianization. The article is based on the analysis of written, material, and visual sources of the 18th–19th centuries. Information about the hairstyles and adornments of the Yakuts is contained within the records of travelers of the 18th–19th centuries. Among the ethnographic works on the peoples of Siberia, one can find drawings depicting maidens and women, where particular attention is given to their hair. These materials were correlated with the data of the archaeological excavations of Yakut female burials of the 18th century. The obtained results were compared with the materials from the 19th century — photographs of women in national costumes and jewelry from museum collections. According to the results of the study, it can be stated that there was a tradition of changing maiden’s hairstyle to woman’s hairstyle in the context of the wedding ritualism. New rules of conduct, social roles, especially regulations on the appearance of women, were formalized in the society in the 19th century with the mass Christianization of the peoples of Yakutia. There were new rules, according to which a woman was not permitted to appear in public with her head uncovered, and therefore the marking function of hairstyles became obsolete. This could explain the absence of rituals and rules associated with women’s hair and hairstyles in the Yakut culture of the 19th–20th centuries.
Alcohol and its functions in the culture of the Khanty of the Surgut Ob region
Authors: Rud’ A.A.
Published: December 2021

The aim of the research is to show the functions of alcohol in the traditional culture of the Eastern Khanty. The basis of the work is formed by the author's field data collected in 2002–2018 in Khanty Surgut Ob region, including the right bank of the Ob River (Lyamin, Pim, Tromyegan, and Agan) and its left bank (Bolshoi Yugan, Malyy Yugan), as well as the right tributary of the Irtysh River (Demyanka). The study of the role of alcohol in the traditional rituals of the Eastern Khanty was based on the methodology of gift exchange proposed by M. Mauss [2011]. The structural-functional approach was used to analyze the functions of alcohol, its place in the traditional culture, and social relations of the Eastern Khanty [Malinovskiy, 2006]. Despite the problems associated with alcoholism, as well as the negative impact on the health of the Eastern Khanty, alcohol performs a number of functions in the traditional culture. The recognition of the legitimacy of alcohol in the traditional worldview is based on the cosmogonic myths. In the ritual sphere, alcohol is a gift to the deities, from whom the indigenous people, in return, expect assistance to a person in hunting and fishing, prosperity, health, and safety. Alcohol performs the function of erasing social boundaries in the community of participants in a traditional ritual. During traditional ritu-als, alcohol is a tool for a person's transition to an altered state of consciousness. In everyday life, alcohol per-forms the functions of relaxation and stress relief. Alcohol serves as a social catalyst when a stranger is included in a traditional collective. Until recently, alcohol occupied not the last place as an equivalent of money in the in-kind exchange of goods and services. At the beginning of the 21st century, structural changes caused by the industrialization of the Surgut Ob region, as well as economic and social reforms of the Post-Perestroika period, led to reduction in the consumption of alcohol by the Eastern Khanty. Today, these changes are represented by two oppositely directed trends. The first tendency is represented by the processes of the revival of traditional culture, nature management, and religion. The second trend includes reappraisal of traditional religion and transition of a part of the Eastern Khanty to Protestantism.
Increasing Equitable Access to Individuals with Disabilities: Participation in Electronic Public Administration Research
Authors: Allgood Michelle
Published: December 2021

Individuals with disabilities (both physical and cognitive) constitute 15% of the global population and 25% of U.S. citizens. However, public administration has not given explicit thought to how current research methods and other data collection processes or tools might exclude individuals with disabilities. This lack of attention to research methods and instruments might impose barriers and limit access to participation for individuals with disabilities who would otherwise meet the requirements for participation within the research design. This omission undermines social equity, a critical pillar of public administration, by systematically excluding individuals with disabilities from the research process. Equitable research ensures that scholars are not excluding participants from the research while obtaining insights from the ‘relevant population.’ Current exclusionary practices raise several questions that are addressed in this essay including: (1) What are the implications of equitable access in electronic research? (2) What are the barriers of access for individuals with disabilities who want to participate in research, like surveys conducted through an electronic delivery system? and (3) What would an equitable data collection and research design look like?
Incompatibility of Published ac Magnetic Susceptibility of a Room Temperature Superconductor with Measured Raw Data
Authors: Hirsch Jorge
Published: December 2021

Room temperature superconductivity has recently been reported for a carbonaceous sulfur hydride (CSH) under high pressure by Snider et al [1]. The paper reports sharp drops in magnetic susceptibility as a function of temperature for five different pressures, that are interpreted as signaling a superconducting transition. Here I question the validity and faithfulness of the magnetic susceptibility data presented in the paper by comparison with the measured raw data reported by two of the authors of ref. [2]. This casts doubt on the assertion of the paper [1] that the susceptibility measurements support the case for superconductivity in this compound.
Assessment of K-Struvite Precipitation as a Means of Nutrient Recovery From Source Separated Human Urine
Authors: Kabdaşlı Işık , Kuşçuoğlu Sezen , Tünay Olcay , Siciliano Alessio
Published: December 2021

The impact of nutrients on the environment, particularly on water bodies, has led to extensive studies for nutrient control. Within this context, studies have been focused on source separation of human urine from domestic wastewater to recover nutrients. Potassium is one of the most important components of human urine. However, data on potassium removal or recovery are quite limited except for some indirect information through use of zeolites for mostly ammonia removal. Potassium struvite or K-struvite (MgKPO4·6H2O) is a sparingly soluble salt belonging to struvite and has the potential of being used as a means of potassium and phosphate recovery from segregated human urine. This study aimed to assess the potential of K-struvite precipitation for control and recovery of nutrients. Within this context, K-struvite precipitation experiments were performed on both synthetically prepared samples and synthetic human urine solution to determine effect of operation parameters i.e. pH, stoichiometry, and temperature on potassium recovery performance. Results indicated that process performance as well as type of solid phases co-precipitated with K-struvite were closely related to initial potassium concentration, pH and reaction stoichiometry. At pH 10, the potassium recovery efficiency was maximized up to 87% by application of 100% excess dose of Mg and P for both synthetic samples and synthetic human urine solution. On the other hand, application of excess dose of K did not provide any improvement in K recovery efficiency. The effect of temperature on solubility of K-struvite was insignificant at the temperature of 24-90°C. Solid phase analyses confirmed that K-struvite was co-precipitated with either Mg3(PO4)2, MgNaPO4·7H2O, or MgHPO4·7H2O depending on pH and stoichiometry instead of a pure compound.
Topic-Feature Lattices Construction and Visualization for Dynamic Topic Number
Authors: Wang Kai , Wang Fuzhi
Published: December 2021

The topic recognition for dynamic topic number can realize the dynamic update of super parameters, and obtain the probability distribution of dynamic topics in time dimension, which helps to clear the understanding and tracking of convection text data. However, the current topic recognition model tends to be based on a fixed number of topics K and lacks multi-granularity analysis of subject knowledge. Therefore, it is impossible to deeply perceive the dynamic change of the topic in the time series. By introducing a novel approach on the basis of Infinite Latent Dirichlet allocation model, a topic feature lattice under the dynamic topic number is constructed. In the model, documents, topics and vocabularies are jointly modeled to generate two probability distribution matrices: Documents-topics and topic-feature words. Afterwards, the association intensity is computed between the topic and its feature vocabulary to establish the topic formal context matrix. Finally, the topic feature is induced according to the formal concept analysis (FCA) theory. The topic feature lattice under dynamic topic number (TFL_DTN) model is validated on the real dataset by comparing with the mainstream methods. Experiments show that this model is more in line with actual needs, and achieves better results in semi-automatic modeling of topic visualization analysis.
Phase-field modeling of nonequilibrium solidification processes in additive manufacturing
Authors: Allen Jeffrey , Moser Robert , McClelland Zackery , Islam Md Mohaiminul , Liu Ling
Published: December 2021

This project models dendrite growth during nonequilibrium solidification of binary alloys using the phase-field method (PFM). Understanding the dendrite formation processes is important because the microstructural features directly influence mechanical properties of the produced parts. An improved understanding of dendrite formation may inform design protocols to achieve optimized process parameters for controlled microstructures and enhanced properties of materials. To this end, this work implements a phase-field model to simulate directional solidification of binary alloys. For applications involving strong nonequilibrium effects, a modified antitrapping current model is incorporated to help eject solute into the liquid phase based on experimentally calibrated, velocity-dependent partitioning coefficient. Investigated allow systems include SCN, Si-As, and Ni-Nb. The SCN alloy is chosen to verify the computational method, and the other two are selected for a parametric study due to their different diffusion properties. The modified antitrapping current model is compared with the classical model in terms of predicted dendrite profiles, tip undercooling, and tip velocity. Solidification parameters—the cooling rate and the strength of anisotropy—are studied to reveal their influences on dendrite growth. Computational results demonstrate effectiveness of the PFM and the modified antitrapping current model in simulating rapid solidification with strong nonequilibrium at the interface.

Published: December 2021

A difusão da ciência do solo é sem dúvida uma prática fundamental de sensibilização quanto à importância do solo como o componente da Terra que sustenta a Biosfera. Dessa forma, o Programa de Educação Tutorial - PET Solos da Universidade Estadual de Santa Cruz (UESC) atua, desde 2010, popularizando a Ciência do Solo com suas ações de ensino/extensão. No entanto, o distanciamento social, como medida para conter a pandemia do Coronavírus SARS-CoV-2, impôs a necessidade de uma nova forma de diálogo e aproximação com o público atendido pelo grupo. Assim, as mídias sociais, que eram utilizadas apenas como plataformas de divulgação, ganharam uma identidade visual e foram adaptadas para a realização de lives, eventos científicos, publicações e disponibilizações de vídeos didáticos, jogos e cartilhas. As estratégias de publicação on-line das ações de extensão basearam-se na regularização da frequência, definição do melhor dia e horário de acordo com o engajamento do público e escolha de conteúdos atuais. A adoção de um novo formato de comunicação do PET Solos com a comunidade acadêmica pelas redes sociais se revelou promissora, considerando-se o aumento expressivo no número de participantes em eventos promovidos, seguidores no Instagram, inscrições no canal do YouTube, e visualizações dos vídeos e lives publicadas. Além disso, são imensuráveis as habilidades desenvolvidas pelos integrantes do grupo que, ao se reinventarem diante de um cenário pandêmico, transformaram as ações de ensino/extensão planejadas para a modalidade presencial, em formato on-line.

O texto apresenta relatos das ações extensionistas realizadas no âmbito do projeto “Oficina de Teatro Circulando” da Escola de Teatro da Unirio, que ocorreram em parceria interinstitucional com o Instituto de Psicologia da UFRJ, durante o biênio de 2020 a 2021. Com a necessidade do distanciamento social decorrente do novo coronavírus (SARS-CoV-2), responsável pela pandemia COVID-19, o que antes acontecia exclusivamente por meio presencial precisou ser reinventado para adequação ao ambiente virtual. A partir das telas de celulares e computadores, novas invenções audiovisuais vêm permitindo a continuidade do projeto Circulando e recriando o diálogo entre as áreas das Artes e da Saúde Mental.
Serum Uric Acid and Calcium Levels as Predictors of Hematoma Volume in Emergency Patients Experiencing Spontaneous Intracerebral Hemorrhage
Authors: Zhang Xiaohui , Ding Hong
Published: December 2021

Objective: To investigate the relationship between serum uric acid and calcium levels and hematoma volume in emergency patients who experienced spontaneous intracerebral hemorrhage (SICH).Methods: Data from 105 patients who experienced SICH and 92 with non-intracerebral hemorrhage (control group) were retrospectively analyzed. Data collected included clinical characteristics, and serum biochemical and blood coagulation indices. Hematoma volume was calculated using computed tomography (CT) imaging data.Results: Individuals who experienced SICH exhibited higher serum uric acid levels and longer activated partial thromboplastin and thrombin times compared to those with non-intracerebral hemorrhage (all P < 0.05). In contrast, serum calcium levels in patients with SICH were lower than those of the control group (P < 0.05). Hypocalcemic patients exhibited a greater median baseline hematoma volume than normocalcemic patients. Conclusion: High serum uric acid and low calcium levels may be predictors of larger hematoma volumes among individuals who experience SICH.

The bacterial and archaeal communities of two biogas producing plants (P1 and P2), associated with a 999 kW cogeneration unit, both located in North Italy, were analyzed at start up and fully operating phases, by means of various molecular approaches: i) Automated Ribosomal Intergenic Spacer Analysis; ii) cloning and sequencing of PCR amplicons of archaeal genes 16Srrna and mcrA; iii) 16S rDNA high throughput next generation sequencing. P1 and P2 use the same technology and both were fed with cattle manure and corn silage. During the study of P1 also the post digestor (fed with pig manure) was analyzed. The aim of this research was to characterize the bacterial and archaeal community in two very similar plants to profile the core microbiome. The results of this analysis highlighted that the two plants (producing comparable quantities of volatile fatty acids, biogas, and energy) differed in anerobic microbiota (Bacteria and Archaea). Notably the methanogenic community of P1 was dominated by the strict acetoclastic Methanosaeta (Methanothrix) (up to 23.05%) and the unculturable Candidatus Methanofastidiosum (up to 32.70%), while P2 was dominated by the acetoclastic, but more substrate-versatile, Methanosarcina archaeal genus (49.19%). The data demonstrated that the performances of plants with identical design, in similar operating conditions, yielding comparable amount of biogas (average of 8662 m3 /day and 7916 m3/day respectively for P1 and P2), VFA (1643 mg/L and 1634 mg/L) and energy recovery (23.90-24 MWh/d) depends on the stabilization of an effective and functionally optimized methanogenic community rather than on the species composition

Published: December 2021

This study includes an approach that addresses how the criteria included in the national Risk Reduction Plans (DRR) of countries are measured quantitatively. Within the scope of the study, disaster management systems and DRR plans of countries with high disaster risk such as Japan, Turkey, Philippines and New Zealand were examined. The main criteria that make up the content of the DRR plans were determined. Risk Identification, Risk Reduction, Response and Recovery, Economic Disaster Risk Management, Disaster Preparedness, Governance and Compliance with Policies and Plans are selected as main criteria. 36 important components completing the main criteria were selected as sub-criteria. Then, all these criteria were weighted using multi-criteria decision-making process called the "Analytical Hierarchy Process". After the experts evaluated the existence of the main criteria and sub-criteria weighted with the AHP, country performance rankings were made for these four countries. As a result of the analysis, Japan was determined as the country with the best DRR plan and implementation, while our country ranked 2nd, New Zealand 3rd and Philippines 4th.

Cadmium (Cd) pollution in soil and particularly in peanuts has attracted global concern and requires urgent attention. Selenium (Se) can alleviate Cd toxicity; however, the underlying mechanisms are not completely understood. Therefore, two varieties of peanut (Arachis hypogaea Linn.) Huayu 23 and Huayu 20 were chosen as the target crops for this study. A pot experiment was conducted to investigate the effects of two Se application methods combined with biochar on the accumulation of Cd and Se, and the best application method was identified. In addition, the role of Se in alleviating Cd toxicity in peanuts was studied. The results indicated that both Se and biochar decreased the Cd content in peanuts and alleviated Cd toxicity. However, the combined application of foliar Se and biochar significantly increased the peanut biomass by 71.50–110.46%, increased the grain yield of Huayu 23 by 0.38–0.47 fold, and Huayu 20 by 2.37–3.47 fold. Additionally, Cd content in peanut grains was decreased by 26.68–50.07%, and Se content was increased by 31.57–99.75 folds. Biochar can decrease the absorption of Cd from the soil, while Se can increase the accumulation of Cd in cell vacuoles by increasing glutathione and phytochelatin to decrease the movement of Cd into the grains. Therefore, our results indicate that the combined application of foliar Se and biochar can effectively promote the enrichment of Se in peanuts and suppress Cd toxicity.

PurposeAlthough pregnancy and childbirth are physiological processes, they may be associated with pelvic floor disorders. The aim of this study was to evaluate the influence of pelvic floor muscle training on postpartum pelvic floor and sexual function of primiparous. MethodsThis is a randomized, prospective study including 300 primiparous women. Inclusion criteria were the delivery of the first, mature baby, the ability to speak, understand German. The participants were evaluated by clinical examinations and questionnaires after 6, 12 months postpartum. After 6 months the women were randomized in two groups. Compared to the control group the intervention groups participated in pelvic floor muscle training once a week over 6 weeks. ResultsThe results of the questionnaires showed no significant differences between the groups after 12 months. A significant stronger pelvic floor muscle strength was found for the intervention group after 12 months. The improvement of the pelvic floor and sexual function over the time showed a significant improvement in both groupsConclusionSupervised pelvic floor muscle training did not improve both the pelvic floor and the female sexual function in comparison to the control group. After 12 months the pelvic floor and sexual function improved significant in all women.Trial registration numberGerman Clinical Trials Register (DRKS00024725), retrospectively registrated
