Актуальность. В настоящее время особенно остро стоит вопрос химического загрязнения почв промышленных городов тяжелыми металлами. Одним из таких примеров является город Свирск, где, помимо мышьяка, вторым по значимости загрязнителем, входящим в отходы производства Ангарского металлургического завода, являлся свинец, средняя концентрация которого в грунтах отвала составляла 1,5…3,0 %.Цель: оценка степени загрязнения свинцом техногенных почв и особенности его миграционной подвижности в почвах и грунтах после ликвидации Ангарского металлургического завода.Объект: техногенные почвы территории бывшего Ангарского металлургического завода г. Свирска.Методы. Фракционный состав соединений Pb изучали методом постадийной экстракции почвы из одной навески. Химический анализ вытяжек и валовое содержание свинца в почве определяли с помощью атомно-абсорбционного метода.Результаты. Установлено, что содержание свинца в техногенных почвах после ликвидации Ангарского металлургического завода превышает ориентировочно допустимую концентрацию в 60–150 раз в зоне бывших отвалов, которая является основным очагом загрязнения. На удалении от этой зоны степень загрязнения почв уменьшается, а миграционная подвижность свинца увеличивается, что может приводить к накоплению его в биообъектах. С глубиной наблюдаются процессы иммобилизации свинца в глинах, что может препятствовать поступлению его в подземные воды и реку Ангару. Основными факторами, влияющими на иммобилизацию свинца в почве, являлись pH, наличие органического вещества, гидроксидов железа, карбонатов и глин. Значительная часть свинца остается связанной с фракцией легко разрушаемых минералов и твердым остатком, что указывает на относительно слабую его мобильность. Изученный механизм подвижности свинца может иметь практическую значимость при проведении мероприятий по рекультивации трансформированных техногенных почв.

Актуальность работы обусловлена необходимостью выяснения роли пирокластического материла в формировании угленосных отложений и геохимического фона редких элементов в углях. Цель: выяснение природы тонштейна из угольного пласта Новый-1а Харанорского буроугольного месторождения. Объекты: угли и тонштейн пласта Новый-1а Харанорского месторождения. Методы: отбор проб из пласта Новый-1а Харанорского месторождения угля; масс-спектрометрия с индуктивно связанной плазмой (ICP-MS), атомно-эмиссионная спектрометрия с индуктивно связанной плазмой (ICP-AES), инструментальный нейтронно-активационный анализ (ИНАА); минеральный состав изучен методами оптической микроскопии, сканирующей электронной микроскопии, рентгенофазовым анализом. Результаты. В ходе исследования был изучен тонштейн из угольного пласта Новый-1а Харанорского буроугольного месторождения. Минеральный состав, структурно-текстурные и геохимические особенности тонштейна позволили установить его апопепловый генезис. Комплекс критериев позволил определить состав исходной пирокластики, из которой сформировался тонштейн. Установлено, что изученный тонштейн сформировался из пеплов трахидацитового состава. Высокие содержания редких элементов-примесей в угле пласта Новый-1а приурочены к участкам контакта c с тонштейном. Наибольшие концентрации в контактовых зонах отмечены для РЗЭ, Zr, Nb, Y, Ta, Hf, Th и U. Набор элементов и их концентрация в тонштейне и в золе угля на контакте с прослоем подтверждают выводы о природе и исходном составе пирокластики, сформировавшей тонштейн.

Published: August 2022

O presente trabalho tem como proposta para o leitor apresentar com clareza a didática do professor de Matemática e o uso dos meios tecnológicos na formação do aluno do ensino fundamental na região Nordeste. Nesse contexto, os meios tecnológicos e a Didática enquanto campo de estudo visam propor princípios, formas e diretrizes que são comuns ao ensino de todas as áreas de conhecimento. Para tanto, surgiu a problematização, pois muitas disciplinas requerem um estudo mais aprofundado, como a Matemática. Como identificar a didática do professor de matemática, utilizando os meios tecnológicos no ensino fundamental da região Nordeste? Pode-se justificar dizendo que a Matemática faz parte da sociedade desde a Antiguidade, sendo obrigação dos professores transmiti-la. Pode-se ainda salientar que a Matemática ensina a pensar, tornando-nos mais aptos, por exemplo, para pensar de forma abstrata e para obter raciocínios dedutivos. Para isso, privilegia a análise das condições de ensino e suas relações com os objetivos, conteúdos, métodos e procedimentos de ensino. A pesquisa tem como objetivo geral verificar a didática utilizada pelos professores com os meios tecnológicos e as dificuldades encontradas na sala de aula na região Nordeste. O artigo constitui-se, portanto, de uma pesquisa bibliográfica do tipo revisão narrativa em que foram analisados artigos, dissertações, teses e/ou livros publicados sobre a temática na última década, dos mais diversos autores, cujas produções encontram-se na internet e bibliotecas, tendo como resultado, após análise, a satisfação de ter o uso das ferramentas de informática como metodologia aplicável em sala de aula, fazendo-se necessário utilizá-las sempre dentro do ambiente escolar.
Inventory for Critical Managerial Soft Skills (ICMS) – Development and Standardisation
Authors: Vadhana R. Chandra , Zakkariya K.A.
Published: August 2022

Purpose: This paper presents the findings of a group of empirical studies for a conceptual and theoretical validation of the Critical Managerial Soft Skills (CMS) Model and then presents the psychometric properties of a newly developed tool - The Inventory for Critical Managerial Soft Skills (ICMS) for assessing the same. Design/methodology/approach: The CMS model was validated by a set of qualitative and quantitative studies among employers to confirm the importance of soft skills and to derive the critical soft skills framework (N-95, 206) and this served as a basis of the tool construction. ICMS has been then psychometrically validated for the group of management graduates by conducting a series of qualitative and quantitative research steps (N-975) Findings: ICMS is a self-reported scale for measuring seven critical managerial soft skills of managerial candidates, namely, Communication skills, Leadership skills, Interpersonal and Teamwork skills, and Self-Management Skills, Decision-making skills, Goal setting skills, and Task efficacy. Research limitations/implications: The tool developed is limited to the measurement of only the seven dimensions which are derived as “critical” based on various stages of the work. Practical implications: The tool can be used for recruitment screening andvas a pre and post-training assessment tool for soft skills development of management students. Social implications: The tool can be used during management education tovhelp the students understand their levels of soft skills and accordingly suitable measures can be undertaken to improve upon during the course of study to enhance their employability. Originality/value: The tool is fully original and has highly useful for researchers and practitioners as it has been empirically validated using appropriate and adequate statistical measures.
Female Genital Mutilation: A Religio-Cultural Sensitive Issue Determining Maternal Health Care Choices among Somali Women in Dadaab Refugee Camp, Kenya

Published: August 2022

The paper addresses Kenya’s development challenges in maternal health care with a specific focus on the impact of traditional birth attendants (TBAs) and female genital mutilation (FGM) among the refugees. It purposes to achieve four objectives: to discuss the persistence of FGM among Somali women in Ifo Refugee Camp, to establish the hospital process of providing maternal health care to mothers who have gone through FGM; find out the level of preparedness of the midwives to handle mothers with religio- cultural concerns such as prayer, non-involvement of male nurses and how the practice of FGM contributes to the preference of TBA by mothers. The study assumes that midwives’ training may not have effectively addressed FGM, a social-cultural sensitive issue affecting childbirth and care. Secondly, the specific support of midwives in refugee camps contexts remains limited. A qualitative research approach was used in the study, involving Snowballing sampling method, in-depth interviews, and focus group discussions (FGDs). These methods brought out pertinent issues that make TBAs the preferential option for some mothers in spite of the presence of level 4 category hospitals in the refugee camps. In case of birth complications, the mother’s choice for TBA delays the family’s decision to take her to the hospital and for health care workers to save mother and child. The shortage of midwives and the presence of male midwives in hospitals make some Somali mothers seek assistance from TBAs. There is a need to contextualize midwifery training by enhancing the curriculum with evidence-based /mother-centered skills.

Introduction: Les troubles électrolytiques sont nombreux et complexes en raison de leurs symptômes non spécifiques et de leurs multiples étiologies. Le but de ce travail est de décrire les désordres ioniques à la Clinique Universitaire d'Urologie et d'Andrologie du Centre Hospitalier Universitaire Hubert Maga Koutoukou de Cotonou, pour en tirer des leçons afin d'élaborer un protocole pour leur prise en charge. Matériels et méthode: Il s'est agi d'une étude descriptive rétrospective avec collecte de données prospective portant sur des patients hospitalisés présentant de trouble électrolytique. Résultats: L'âge de nos patients variait de 25 à 86 ans avec une moyenne de 63,58 ans. La catégorie des retraités était la plus représentée dans 39,10% des cas suivie des fonctionnaires (24,36%). La découverte fortuite de troubles électrolytiques était plus représentée dans 86,54% des cas. L'admission était indépendante des troubles électrolytiques dans 83 % des cas. Les troubles électrolytiques étaient plus fréquents chez les patients opérés en période préopératoire dans 32,70 % des cas. La dysnatrémie prédominait dans 49,72% des cas suivie de la dyskaliémie (40,78%). Sur le plan qualitatif, l'hyponatrémie était prédominante dans 30,72% des cas suivie de l'hypokaliémie (17,33%). Dans notre série, les troubles électrolytiques étaient légers dans 72,43 % des cas avec une échelle de morbi-mortalité de 1 (retour à domicile). Conclusion: Les troubles électrolytiques sont grevés d'une morbi-mortalité non négligeable et sont principalement représentés par la dysnatrémie et la dyskaliémie. Ces troubles sont souvent la conséquence d'une uropathie obstructive vue au stade des complications. La mise au point d'un protocole standardisé dans un service d'urologie permet une prise en charge optimale des troubles ioniques en urologie.

Le prospect de Woulo-Woulo est situé au sud-est de la Côte d’Ivoire précisément dans la zone de Maféré, à environ 8 km à l’ouest du couloir de cisaillement d’Aféma. Le prospect Woulo-Woulo est constitué de métasédiments (métagrauwackes et métaargilites), de métavolcanites (laves andésitiques et brèches) et d’intrusions de métarhyolites porphyriques et de métagabbros. Ces différentes lithologies ont été affectées par une importante activité hydrothermale matérialisée par des veines et veinules de quartz, carbonates (calcite ± dolomie), ± tourmaline, ± sulfures. La minéralisation aurifère du prospect de Woulo-Woulo est encaissée préférentiellement dans la métarhyolite porphyrique déformée et hydrothermalisée. Cependant, cette minéralisation apparait principalement liée aux veines et veinules de quartz et carbonates et présente donc un contrôle structural. C’est une minéralisation de type filonien et hydrothermale donc épigénétique. Cette activité hydrothermale a induit une altération pervasive des encaissants entrainant une carbonatation, une silicification, une chloritisation, une séricitisation et une épidotisation. La paragenèse métallifère est constituée de pyrite (sulfure principal), blende ou sphalérite et or natif.

O BIOMÓRFICO COMO CONSTRUÇÃO POÉTICA DA SÉRIE ESTRUTURAS DA VIDA
Authors: Morokawa Rosi
Published: August 2022

Este artigo é o resultado de uma pesquisa sobre o biomórfico como caraterística de construção poética da série de pinturas e gravuras intitulada Estruturas da Vida. Inicia-se com uma pesquisa sobre a terminologia e uso do conceito de biomórfico na história da arte. Entende-se por formas ou imagens biomórficas aquelas que evocam formas vivas, orgânicas, como plantas e o corpo humano, características presentes em obras do movimento Surrealismo, assim como da Arte Contemporânea. Busca-se, então, relações e aproximações entre as características biomórficas e a construção poéticas dos trabalhos da série Epitélios, culminando na série Estruturas da vida. As séries foram desenvolvidas a partir de imagens microscópicas, que nos remetam a algo que não podemos ver a olho nu, mas que compõem e estruturam todas as formas vivas complexas no mundo.

O ENSINO DE DANÇA E A DESNATURALIZAÇÃO DO OLHAR FRENTE À INFLUÊNCIA MASSIVA DA VIDEOSFERA
Authors: Silva Melo Glenda Maíra
Published: August 2022

Este artigo discute a conjuntura educacional gerada pelo comportamento de alunos e professores acostumados à mera reprodução de coreografias exibidas pelos meios constitutivos da videosfera (programas de televisão, canais do youtube, etc.) sem consciência da interação corpo-mente necessária para transformar meros passos em expressão artística. Visando sensibilizar os alunos dos cursos técnicos de nível médio do IFTM, desenvolveu-se uma metodologia de ensino inspirada na obra Deslocamentos da coreógrafa Marta Soares. Através da (o) problematização de movimentos, incentivo à reflexão e ampliação do repertório cultural dos alunos foi possível promover a desnaturalização do olhar frente ao que é retratado como banal na dança.
The Rise of International and Local Media Outside the West: Really Helps Counter-hegemonic News?
Authors: Di Xiyan
Published: August 2022

The rise of third world media in recent years seems to be starting to change the monopoly of Western journalism by media outlets like the BBC and CNN. This article critically analyses the current situation of local media through the perspectives of anti-hegemonic journalism, soft power, press freedom and orientalism, with examples such as Al Jazeera, RT and Phoenix TV. The analysis reveals that the local media do have a limited freedom of the press through an independent business model that plays a counter-hegemonic journalistic role. At the same time, however, the complexity of political, economic and religious beliefs still severely restricts its growth.
Information Manipulation of Securities Market Crimes Revisited: From the Perspective of the Amendment XI to the Criminal Law
Authors: Fu Feixiang
Published: August 2022

In 2020, the Amendment XI to the Criminal Law and the Latest Judicial Interpretation in 2019 by the Supreme Court and Supreme Procuratorate have made information manipulation a key target of regulation. Information manipulation is a new type of securities manipulation crime in which the perpetrator relies on the abuse of information advantage to induce investors to make decisions in order to indirectly influence the securities market. This behavior has some similarities with traditional trading manipulation, but there are still significant differences in the manipulation methods and the infringement of legal interests, and it is necessary to clarify the rules of its judicial application with typical cases. In addition, it is difficult to judge the subjective intent of information manipulation. Due to the complexity of the act, the previous path of subjective intentional determination has been difficult to apply, so it is necessary to try to establish the judicial presumption path of “objective proof of subjective”. This path is achieved by considering three elements: objective behavior, purposeful intent and complementary factors, which are used to judge the subjective intent of information manipulation.
An Analysis of the Transformation of Social Media to “Social Factory” -Based on the Perspective of Communication Political Economy
Authors: Chen Anqi
Published: August 2022

With the advent of the Web2.0 era, human nature’s desire for communication has been activated at the technical level. While more and more users are using social media, Internet-related companies are also trying their best to satisfy people’s fantasies about the form of communication by developing various new forms of social software. However, in fact, many social media are under the guises of social media, but their essence is the logic of capital. From the perspective of the political economy of communication, this paper argues that social media has become a “social factory”, and with the expansion of the “social factory”, the entire society will gradually become factory-like.
PENSAR O BRASIL. PROVOCAÇÕES DE DUAS COMEMORAÇÕES EMBLEMÁTICAS

Published: August 2022

O ano de 2022 é marcado por duas comemorações emblemáticas no Brasil: os 200 anos de sua Independência (07 de setembro) e os 100 anos da Semana de Arte Moderna (13-17 de fevereiro). Embora muito distintas, pois a primeira remete ao "evento fundador" da autonomia política do país e a segunda a uma manifestação artístico-cultural propondo uma nova visão estética, inspirada nas vanguardas europeias, essas comemorações são um convite para pensar o Brasil, seja do ponto de vista histórico, seja do ponto de vista social, econômico, político, cultural, filosófico e, certamente, teológico.
ANTROPOFAGIA E TEOLOGIA
Authors: De Mori Geraldo Luiz
Published: August 2022

2022 é marcado por duas comemorações importantes no Brasil: os 200 anos de sua independência (dia 7 de setembro) e os 100 anos da Semana de Arte Moderna (13-17 de fevereiro). Embora remetam a eventos distintos, essas comemorações são uma ocasião favorável para de novo perguntar-se sobre o Brasil e os brasileiros, sua história, identidade, destino. Dentre os protagonistas da Semana, Oswald de Andrade foi, sem dúvida, um dos mais provocativos, tendo elaborado, nos anos que se seguiram, uma teoria sobre o Brasil e os brasileiros a partir da metáfora da antropofagia. Após alguns esclarecimentos metodológicos, o presente estudo apresenta o pensamento antropofágico oswaldiano, identificando em sua busca do "humanum" alguns elementos de uma possível "correlação mutuamente crítica" entre esse "clássico" do pensamento brasileiro e a teologia cristã.

Authors: Santos Sílvio Marques Sousa , Nascimento Elimar Pinheiro do , Pinto Fraxe Terezinha de Jesus
Published: August 2022

Neste artigo, o objetivo é apresentar o caminho sinodal, o qual faz da Prelazia do Xingu uma atriz relevante política e socioambiental no conflito socioambiental causado pelo projeto da hidrelétrica de Belo Monte em Altamira no Pará. A fundamentação teórica, à luz da sinodalidade, relê a eclesiologia do Concilio Vaticano II e sua recepção nas conferências do CELAM, nas Assembleias dos bispos na Amazônia e nas assembleias prelatícias. O método foi a análise de conteúdo que dispõe de elementos diacrônicos para a crítica dos diversos níveis da estrutura eclesial e sincrônicos para exame doutrinal à luz dos documentos eclesiais e fontes próprias da pesquisa como as entrevistas. Os resultados da análise permitem a compreensão da relevância social e política da ação evangelizadora da Prelazia do Xingu, da década de 70 até os dias atuais, como fruto de uma Igreja essencialmente sinodal.

Authors: Rivera-Lozada Oriana , Rivera-lozada Isabel Cristina , Bonilla-Asalde Cesar Antonio
Published: August 2022

Access to health services compromises therapeutic adherence in patients with HTN, which is a risk factor for cardiovascular disease and premature death. The aim of the research is to determine the influence of access to health services on adherence to antihypertensive treatment during the COVID-19 pandemic. We included a cross-sectional analytical study. A survey was applied to 241 hypertensive patients at the Daniel Alcides Carrión Hospital, Callao-Peru. Data were analyzed using SPSS software. Absolute and relative frequencies were reported and the chi-square test was applied with a statistical significance level of p<0.05. In addition, multiple logistic regression analysis was performed using the Stepwise method. An association was found between non-adherence to treatment and health expenses (ORa: 1.9 CI 95% 1.7-2.2), not receiving care due to lack of a doctor (ORa: 2.8 CI 95% 1.5-3.2), having difficulty with schedules (ORa: 3.7 CI 95% 2. 3-5.5), fear of receiving care at the hospital (ORa: 4.5 CI 95 % 2.7-6.8), trust in health personnel (ORa: 7.5 CI 95% 2.3-10.5) and considering that the physician does not have enough knowledge (ORa: 3.1 CI 95% 2.4-7.8). Therapeutic adherence was associated with physician availability for care, difficulty with schedules, fear of being seen in the hospital, trust in health personnel, and waiting time.

Authors: Tarigan Christine Ulina , Tarigan Wenny Pinta Litna
Published: August 2022

This study was to find out the effects of flipped class with project-based learning (PjBL) dimensions assisted by Moodle combined with reading, questioning and answering (RQA) strategies on students’ 21st-century skills. The research was quasi-experimental with cluster random sampling technique. The sample was three classes of twelve graders at a private school. The first class applied flipped class with project-based learning assisted by Moodle combined with RQA. The second class applied flipped class learning assisted by Moodle without PjBL and RQA. And the control class applied conventional online learning using Moodle only. Each class consists of 25 students. The instrument was an essay test with 10 questions. The collaboration and communication skills were assessed using observation sheets. The average of these two values used as a reference to determine the predicate of students’ 4C ability. The normality and homogeneity tests found that the three classes were the same and normally distributed (sig.>0.05). The results of ANOVA test and student’s response observation showed significant differences in three classes S1, S2 and S3 (α = 0.05, sig.0.00). The first class shows the highest 4C skills results followed by the second and third treatment classes with average scores respectively 91.25; 91.52 (very competent), 83.32; 83.04 (very competent) and 73.74; 73.64 (competent). These findings were expected to be a recommendation for educators to integrate the 4C skills through flipped class to improve students’ skills.

Produced water (PW) is the most significant waste product in oil and gas exploitation, and numerous challenges are associated with its treatment. For over half a century, PW treatment and handling have evolved from a waste product to a reusable stream for the petroleum industry. PW is reused and recycled for hydrocarbon recovery processes, well completion, stimulation, drilling, etc. Despite this usage, enormous volumes are still required to be disposed of in the subsurface aquifers or surface water bodies after treatment. Challenges to PW treatment are related mainly to widely varying PW characteristics, nonuniformity of water treatment systems for different fields, and difficulty in designing novel technology due to changing production rates and other design parameters. This paper focuses on purpose-specific water treatment units used in various activities within the oil and gas industries and technological advancement. A detailed account of the historical development of current water treatment practices, disposal, available technology, and challenges in implementation are presented. Forward-looking recommendations are given on how emerging technologies can be integrated into everyday oil and gas activities to achieve the purpose-specific treatment goal.
Generation of cell lines for the exon-specific isoform expression reporter system (EXSISERS)

Published: August 2022

Exon-specific isoform expression from alternatively spliced mRNA is a fundamental mechanism that substantially enriches a cell’s proteome. However, conventional methods to assess alternative splicing are either consumptive and work-intensive or do not quantify isoform expression over multiple time points and at the protein level. We thus developed an exon-specific isoform expression reporter system (EXSISERS), which non-invasively reports the translation of exon-containing isoforms by scarlessly excising reporter proteins from the nascent polypeptide chain via highly efficient, intein-mediated protein splicing. EXSISERS enables non-invasive monitoring of exon-specific isoform expression with high sensitivity and cellular resolution and enables high-throughput screening of exon-specific therapeutic interventions.This protocol on how to generate EXSISERS reporter cell lines is related to the publication ‘Non-invasive and high-throughput interrogation of exon-specific isoform expression’ in Nature Cell Biology.

The current study aimed at exploring university students’ perspectives on the emergency distance education strategy that was implemented during the COVID-19 crisis in Jordan, one of the countries in the Eastern Mediterranean Region. Utilizing a qualitative design supported by Moore’s theory of transactional distance, a total of 17 semi-structured interviews were conducted with university students of various study levels and disciplines. Data were inductively analyzed using thematic analysis as suggested by Braun and Clarke. Seven themes have emerged, including, (i) Students’ psychological response to the sudden transition in educational process, (ii) Students’ digital preparedness, equality, and digital communication, (iii) Students’ and teachers’ technical competencies and technostress, (iv) Student-student and student-teacher interpersonal communication, (v) Quality and quantity of learning materials, (vi) Students’ assignments, examinations, and non-reliable evaluation methods, and (vii) Opportunities with positive impact of distance learning. The study findings provide evidence that the sudden transition from traditional on-campus to online distance education was significantly challenging in many aspects and was not a pleasant experience for many participants. Various factors under the jurisdiction of academic institutions and decision-makers are considered main contributing factors to the students’ educational experiences amid the pandemic crisis. Therefore, better planning and more sustainable utilization of educational resources have paramount importance in providing a high-quality education. Additionally, more dedicated efforts in terms of equitable, reliable, and credible evaluation systems should be considered in Jordan’s distance education strategy.
Numerical study of the volcano effect in chemotactic aggregation based on a kinetic transport equation with non-instantaneous tumbling
Authors: YASUDA Shugo
Published: August 2022

Aggregation of chemotactic bacteria under a unimodal distribution of chemical cues was investigated by Monte Carlo simulation and asymptotic analysis based on a kinetic transport equation, which considers an internal adaptation dynamics as well as a finite tumbling duration.
It was found that there exist two different regimes of the adaptation time, between which the effect of the adaptation time on the aggregation behavior is reversed; that is, when the adaptation time is as small as the running duration, the aggregation becomes increasingly steeper as the adaptation time increases, while, when the adaptation time is as large as the diffusion time of the population density, the aggregation becomes more diffusive as the adaptation time increases. Moreover, notably, the aggregation profile becomes bimodal (volcano) at the large adaptation-time regime while it is always unimodal at the small adaptation-time regime. The volcano effect occurs in such a way that the population of tumbling cells considerably decreases in a diffusion layer which is created near the peak of the external chemical cues due to the coupling of diffusion and internal adaptation of the bacteria.
Two different continuum-limit models are derived by the asymptotic analysis according to the scaling of the adaptation time; that is, at the small adaptation-time regime, the Keller-Segel model while, at the large adaptation-time regime, an extension of KS model, which involves both the internal variable and the tumbling duration. Importantly, either of the models can accurately reproduce the MC results at each adaptation-time regime, involving the volcano effect. Thus, we conclude that the coupling of diffusion, adaptation, and finite tumbling duration is crucial for the volcano effect.

Published: August 2022

BackgroundThe aim of this study was to find the best surface treatment for provisional crowns made in the laboratory (CAD/CAM) allowing optimal bond strength of brackets.MethodsThe sample consists of 30 lower bicuspids and 180 provisional teeth. The provisional teeth were randomly divided into 6 different groups. The orthophosphoric acid etching (37%) was applied to the 30 lower bicuspids. The provisional teeth had undergone different surface treatments. Group 1: No treatment (Control Group). Group 2: Diamond bur. Group 3: Sandblasting. Group 4: Plastic Conditioner. Group 5: Diamond bur and Plastic Conditioner. Group 6: Sandblasting and Plastic Conditioner. The brackets in all groups were identically placed using the Transbond XT® Primer and the Transbond XT® Paste. Then, the entire sample underwent an artificial aging procedure and a measurement of the bond strength was done. After debonding, the surface of the teeth was examined to determine the quantity of the adhesive remnant.ResultsNatural teeth recorded the highest average followed by the averages of groups 5 and 6. However, group 1 recorded the lowest average. Groups 2 and 4 had very close averages as well as groups 5 and 6. A statistically significant difference between the averages of all groups was recorded (p<0.001) except for groups 2 and 4 (p=0.965) on the one hand and groups 5 and 6 (p=0.941) on the other hand.DiscussionThe bonding of brackets on provisional teeth is considered as a delicate clinical procedure. In fact, unlike natural teeth, the orthophosphoric acid usually used, does not have any effect on the surface of provisional restorations. Several surface treatment techniques were proposed to enhance the bond strength between the orthodontic brackets and the surface of the provisional restorations.Moreover it is difficult to simulate the exact intra-oral environment conditions.ConclusionUsing a diamond bur combined with the Plastic Conditioner and sandblasting combined with that same product resulted in a bond strength close to natural teeth.
Rb-Sr isotope evolution in Earth and the preferred decay constant of 87Rb
Authors: Gargi Satya
Published: August 2022

Any model trying to define the Rb-Sr isotope evolution in the planet Earth/Solar/System has to specify the beginning 87Sr/86Sr isotope ratio of the planet Earth at the time of its formation, its present-day Sr isotope ratio and the 87Rb/86Sr ratio. Furthermore, such a model attempting to describe this evolution has to take into account several other factors such as age of the Earth, decay constant of 87Rb, present-day Rb/Sr ratio, and isotopic characteristics of the mantle as seen through the initial Sr isotope ratios of certain ancient mantle-derived rocks because these factors impose significant constraints on this evolution. The present study shows that one model for the isotopic evolution in the Earth/Solar System which stipulates beginning (initial) and present-day Sr isotope ratios of 0.69877 and 0.7047, respectively, and a present-day 87Rb/86Sr ratio of 0.09, satisfies all the abovementioned constraints. However, for this model to be feasible, the age of the Earth must be assumed to be similar to the mean age of the meteorites, that is, 4.555 Gyr, and the decay constant of 87Rb must be revised to a lower value of 1.4087(10− 11 yr− 1).

Published: August 2022

Background
It has been considered that virologic failure can occur with drug-resistance mutations in the HIV genome. In the present study, we assessed the influence of growth capability of HIV strains to drug response resulting in virologic failure. Phytohemagglutinin-activated peripheral blood mononuclear cells (1.5×106 cells) were infected with HIV strains (106 copies/mL) in vitro. The culture was carried out in different concentrations (0.001 to 20 µM) of twelve commercially available antiretroviral synthetic compounds (five nucleoside/nucleotide reverse transcriptase inhibitors, one non-nucleoside reverse transcriptase inhibitor, four integrase inhibitors, and two protease inhibitors), and HIV production was assessed using HIV-RNA copies in culture. The 90% inhibitory concentration (IC90) was used as an indicator of antiviral activity.
Result
Tenofovir (TFV) showed an IC90 of 2.05 ± 0.71 µM above the maximum concentration that a drug achieves (Cmax) after dosing of Tenofovir disoproxil fumarate (prodrug of TFV) against a strain with high growth capability without any drug resistance-related mutations. Lamivudine, emtricitabine, and efavirenz had IC90 values close to the Cmin-Cmax range against the strain. Atazanavir, tenofovir alafenamide, zidovudine, and dolutegravir had the lowest IC90 values of 0.03, 0.40, 0.50 and 0.50 nM, respectively, against the strain.
Conclusion
These results suggest that high growth capability of the strains influences virologic failure.

Published: August 2022

At the age of ever replenishing data with constant inflow, it is very tedious to classify astronomical objects manually which was the conventional way for a long time. The universe is full of stars clustered together to form galaxies. The study and analysis of these galaxies provides us with a vast understanding of our own galaxy. A deep convolutional neural network architecture for galaxy morphology classification and feature prediction is proposed. The galaxy can be divided into ten morphological classes based on its characteristics. The proposed architecture consists of two models: one for class prediction and the other for galaxy features prediction. This paper attempts to classify astronomical objects into Galaxies, Stars and Quasars using data from SDSS, LAMOST Surveys in addition to spectroscopic data analysis. Baseline approaches are compared for the classification task and improved optimised classification is further explored.
