The Western Ethiopian Shield is underlain by volcano-sedimentary terranes, gneissic terranes, and ophiolitic rocks intruded by different granitoid bodies. The Megele area is part of Western Ethiopian Shield and consist of a low-grade volcano-sedimentary zone that has been intruded by mafic (dolerite dyke) and granitoid intrusions (granodiorite, diorite, granite gneiss). To establish the origin of the distinctive lithologies of the locality and evaluate its mineral potential, petrological, petrographical, and geochemical characterization of these rocks were carried out. Hence, the lithological, geochemical, and petrogenetic features of the Neoproterozoic granitoid intrusives and associated metavolcanic, were illustrated through a combination of field mapping, petrological, and geochemical analysis. The petrological result obtained from the thin section analysis of the granitoids and metabasalt from Megele area indicates that, these rocks has been metamorphosed from lower green-schist facies to lower amphibolite facies as denoted by mineral assemblages such as albite + muscovite + prehnite+ quartz and actinolite + hornblende + epidote + garnet. The major and trace element geochemical analysis of granodiorite, diorite, and granite gneiss revealed that the rocks in the studied area were mainly calc-alkaline and peraluminous in nature in the SiO2 versus Na2O+K2O and A/NK versus A/CNK, the details of the results on the major and rare elements are stated in the result section respectively. The granitoids are S-type granites revealed silica saturated rock formed at the volcanic arc subduction (VAG) to syn-collisional (syn-COLD) tectonic setting by fractionation of LREE-enriched, HREE-depleted basaltic magma with considerable crustal input. This basaltic magma seems to be generated from the LREE-enriched, HREE-depleted mantle. In conclusion, the metabasalt is sub-alkaline (tholeiitic), metaluminous bodies generated at mid-oceanic ridge tectonic setting by partially melting of HREE-depleted and LREE-enriched basaltic magma. The magma sources are associated with the reworked sediment-laden crustal slabs from the subduction zone and resulted in S-type granitoid.

Published: December 2022

ABSTRACTThe Collaboratory for the Study of Earthquake Predictability (CSEP) is an international effort to evaluate probabilistic earthquake forecasting models. CSEP provides the cyberinfrastructure and testing methods needed to evaluate earthquake forecasts. The most common way to represent a probabilistic earthquake forecast involves specifying the average rate of earthquakes within discrete spatial cells, subdivided into magnitude bins. Typically, the spatial component uses a single-resolution Cartesian grid with spatial cell dimensions of 0.1° × 0.1° in latitude and longitude, leading to 6.48 million spatial cells for the global testing region. However, the quantity of data (e.g., number of earthquakes) available to generate and test a forecast model is usually several orders of magnitude less than the millions of spatial cells, leading to a huge disparity in the number of earthquakes and the number of cells in the grid. In this study, we propose the Quadtree to create multi-resolution grid, locally adjusted mirroring the available data for forecast generation and testing, thus providing a data-driven resolution of forecasts. The Quadtree is a hierarchical tree-based data structure used in combination with the Mercator projection to generate spatial grids. It is easy to implement and has numerous scientific and technological applications. To facilitate its application to end users, we integrated codes handling Quadtrees into pyCSEP, an open-source Python package containing tools for evaluating earthquake forecasts. Using a sample model, we demonstrate how forecast model generation can be improved significantly in terms of information gain if constrained on a multi-resolution grid instead of a high-resolution uniform grid. In addition, we demonstrate that multi-resolution Quadtree grids lead to reduced computational costs. Thus, we anitcipate that Quadtree grids will be useful for developing and evaluating earthquake forecasts.
Characterizations of Fourteen (2021-2022) Proposed Discrete Distributions
Authors: Hamedani G.G. , Roshani Amin 
Published: December 2022

As we mentioned in our previous works, sometimes in real life cases, it is very difficult to obtain samples from a continuous distribution. The observed values are generally discrete due to the fact that they are not measured in continuum. In some cases, it may be possible to measure the observations via a continuous scale, however, they may be recorded in a manner in which a discrete model seems more suitable. Consequently, the discrete models are appearing quite frequently in applied fields and have attracted the attention of many researchers.
Characterizations of distributions are important to many researchers in the applied fields. An investigator will be vitally interested to know if their model fits the requirements of a particular distribution. To this end, one will depend on the characterizations of this distribution which provide conditions under which the underlying distribution is indeed that particular distribution. Here, we present certain characterizations of 14 recently introduced discrete distributions.
Comparative analysis of serum and sebum concentration of super-bioavailable itraconazole 50 versus 65 mg in healthy adult volunteers

Published: December 2022

<p>Super-bioavailable itraconazole (SBITZ) is a new form of itraconazole which overcomes the pharmacokinetic issues of conventional itraconazole (CITZ). Currently two strengths are approved globally for SBITZ; 50 mg and 65 mg which exhibit greater bioavailability than CITZ and widely prescribed in systemic mycosis and dermatophytosis. Though both the strengths have proven to be bioequivalent with CITZ 100 mg but difference was reported in achieving therapeutic concentration of ITZ in patients. Secondly, skin kinetics study in terms of sebum concentration is lacking for both the strengths.</p>
Antropologia da vida diante da catástrofe
Authors: Caballero Indira Viana , Vieira Suzane De Alencar , Fujigaki Alejandro 
Published: December 2022

A proposta deste dossiê orientou-se por uma questão pragmática: como criar uma antropologia da vida no momento em que somos perturbadas/os pela catástrofe? Como habitar um mundo em ruínas, territórios existenciais devastados pelas mortes em série da pandemia da Covid-19 e por catástrofes ecológicas e climáticas? Nosso objetivo foi testar ferramentas e conhecer outros arranjos ecológicos para tornar habitáveis nossos mundos pessoais e coletivos devastados ou em vias de sê-lo e despertar reflexões para lidar com a catástrofe. Ocupar-se com a vida interconectada com a morte nos mostra a necessidade de não apenas aprendermos a viverbem, mas considerarmos morrer da melhor forma possível. O desafio consiste em buscar escutar, descrever e derivar consequências do chamado dos povos tradicionais sobre a persistente catástrofe colonial e capitalista que se acopla à pandemia e à catástrofe ecológica global.

Published: December 2022

Physical activity has numerous health benefits, including better cardiorespiratory fitness, skeletal health, psychological health and reducing obesity. However, more than 80% of adolescents worldwide are not active enough, failing to meet the recommended 60 minutes of daily physical activity, and due to COVID-19 restrictions, the percentage might be even higher. Objective: This study aimed to investigate the level of physical activity and its influencing factors in a sample of 333 middle school students (mean age = 12.93, SD = 1.20) from Cluj-Napoca, Romania, during the COVID-19 pandemic. Methods: A cross-sectional study was conducted and two instruments were used to assess interest variables, the Physical Activity Questionnaire for Older Children and the Cues, Perceived Benefits and Barriers to Physical Activity Questionnaire. Results showed a low level of physical activity in our sample for both male (M = 2.76, SD = 0.76) and female (M = 2.62, SD = 0.63) adolescents. The most commonly reported cue to physical activity was “encouragement from parent(s) to exercise”, the most prevalent perceived benefit was “to stay in shape”, and the most powerful barrier was “wanting to do other things with personal time”. Conclusion: Understanding adolescents’ cues, perceived benefits and barriers to physical activity could help teachers and coaches to provide suitable programmes, and parents or peers to support adolescents. Discussion includes implications for practice and guidelines for policymakers and participants.

O artigo objetiva discutir sobre juventudes e Assistência Social, examinando-se as diretrizes desta política junto aos jovens na realidade brasileira pós-Constituição Federal de 1988. A metodologia utilizada consistiu em estudo bibliográfico e documental, analisando-se os aspectos que perpassam o reconhecimento das juventudes como sujeitos de direitos e os principais programas implementados para jovens a partir dos anos 2000 no Brasil, tendo como base uma discussão acerca das diretrizes postas para os serviços socioassistenciais e para a gestão do Sistema Único de Assistência Social (SUAS), de forma a examinar se estas contribuem para a visibilidade de interesses, demandas e necessidades, bem como para a assistência e a participação destes segmentos sociais. Os resultados evidenciam que, a partir da criação da Secretaria Nacional de Juventude e da aprovação do Estatuto da Juventude, houve a incorporação de algumas ações na agenda pública brasileira com base em programas para jovens vulneráveis, sobretudo, na preparação para o trabalho, que dão continuidade a uma perspectiva de setorialização, considerando que não configuram uma dimensão mais universalista. No âmbito da política de Assistência Social, essa perspectiva é reiterada no contexto do SUAS, diante da fragilidade dos mecanismos de participação de jovens e da insuficiência/fragilidade dos serviços que são ofertados para estes segmentos sociais.
Translation-based task in an ESP classroom: Tlemcen University as a case study
Authors: Fehaima Amaria 
Published: December 2022

Integrating translation in English for specific purposes (ESP) teaching and learning is a crucial issue since the last decade of the 20th century. This paper aims to analyse the role of translation as a helpful tool for ESP classes on the use of translation in ESP teaching and learning. Therefore, a case study is employed to describe the necessity of using translation in ESP classes, especially, for third-year computer science students at the University of Tlemcen. A mixed method was used; a questionnaire was administered to ESP teachers in the Department of Science and Technology, and classroom observation on third-year students of computer science was conducted. The results revealed that computer sciences students at the University of Tlemcen faced various hindrances when dealing with professional resources which are mainly at the level of content due to the nature of ESP courses they were exposed to during their studies.

Authors: Budiman Johan , Thobari Jarir At , Pinzon Rizaldy Taslim 
Published: December 2022

It was estimated that patients with ischemic stroke and post-stroke cognitive impairment (PSCI) have been increasing. In addition, this PSCI is often late diagnosed when it has already developed into post-stroke dementia. Only a few studies have developed a scoring system of predictor factors cognitive impairment (CI) for post-acute ischemic stroke in Indonesia. This study aimed to develop a scoring system of predictor factors of CI for post-stroke ischemic patients. The patients included were >18 years old diagnosed with acute ischemic stroke who underwent mini-mental state examination (MMSE) and clock drawing test (CDT) examination on day-30 at Bethesda Hospital Yogyakarta. It was retrospective cohort study design and samples were obtained from the stroke registry and medical records. Patients who had a history of CI and incomplete medical records were excluded. The results of MSSE and CDT at day-30 were the outcomes of this study. To evaluate the relationship between the independent variable and the dependent variable, chi-squared tests were perforemd followed by multivariate logistic regression analysis with Hosmer-Lemeshow tests with backward likelihood-ratio (LR) method and by assessing the final area under the curve (AUC) model. The final model was transformed into a scoring system to determine the value of probability prediction of PSCI, the optimal cut-off point, the sensitivity value and specificity value of the cognitive impairment scoring system at day-30 after acute ischemic stroke. A total of 140 subjects were included in the study with an average age of 62.8 years, 86 (61.4%) males and 54 (38.6%) females. Ninety-one subjects (65%) experienced post-stroke CI. The multivariate analysis showed age >70 years, education level ≤6 years, modified ranking score (mRS) >3 at diagnosis, Barthel index score ≤4 at diagnosis, the number of multiple lesions and the location of lesion in the cortex were independent predictor factors affecting CI 30 days after acute ischemic stroke. The developed predictor score obtained AUC discrimination value of 82.6% (95%CI:0.757-0.896) and calibration value of p>0.366. The scoring system had a value range of 0-7, and with a cut-off ≥1, it had a sensitivity value of 86.8% and a specificity value of 59.2%. It can be concluded that the predictor score has a good performance in predicting the occurrence of PSCI at day-30 after acute ischemic stroke.
Gender Agenda in Classroom and Student Educational Outcomes
Authors:   , Kamal Zahra 
Published: December 2022

The research projects in this dissertation lie under the umbrella theme of gender interactions in classroom environment and the impact on student achievement, with implication for the optimal allocation of educational resources in order to improve students’ performance and promote educational equality. - The first project (chapter 2) investigates the causal impact of participation in single-sex rather than coeducational classrooms on student performance at higher educational level, using a natural experiment setting in a country where single-sex schooling is highly prevalent. - The second project (chapter 3) examines the association between the classroom gender composition and the student math achievement via a cross-country analysis of TIMSS data. - The third project (chapter 4) looks into the student-teacher gender interaction, providing evidence for the causal impact of teacher gender on student performance in the previously-unexamined contexts of Muslim-majority countries. My research findings provide important implications for the policy-making not only in Muslim countries but also for western societies with large inflows from the middle-eastern countries. Destination countries mostly face serious challenges of integrating their new members into the mainstream society. Despite their well-designed policies to address these challenges, they sometimes end up with unintended negative outcomes or simply do not reach their integration goals. In fact, certain distinct aspects of Muslim culture that naturally induced contradictory mechanisms had been initially overlooked by the policymakers. Similarly, the so-called cultural ignorance might cause policymakers to pass over some of the potentially strong and effective policy levers to address integration issues. A closer look on the gender dynamics in classroom could provide insights for accelerating the reforms with integration goals and promoting educational equality in destination countries.
A independência do Brasil através dos parlamentares portugueses
Authors: Mourão Alda 
Published: December 2022

Quando o Brasil passou a ser o centro do império português, deslocado da Europa para a América, criaram-se condições para a mudança de regime: Portugal aderiu ao Liberalismo (1820). Os trabalhos parlamentares, iniciados em 1821 e que se prolongaram até 1823, espelhavam os receios do regresso ao passado e tornavam visível a fragilidade ideológica das Cortes, onde as discussões preparavam o regresso do absolutismo e aumentavam a vontade de separação aos brasileiros Após a declaração da indepndência do Brasil, as relações entre os dois territórios tiveram um fórum de discussão privilegiado nas Cortes. A análise da forma como os parlamentares discutiram o novo quadro político que passaria a reger as relações Portugal-Brasil é o tema deste texto.

O manuscrito tem a finalidade de analisar o percurso histórico dos últimos pleitos eleitorais do SINDEDUCAÇÃO que culminaram na eleição da chapa de oposição para a direção do Sindicato dos Profissionais do Magistério do Ensino Público de São Luís (SINDEDUCAÇÃO), em novembro de 2020. Se dispõe a contribuir com o desvelamento do significado político dos pleitos eleitorais para a vanguarda política da categoria de professores, que em meio a desafios envolvendo a precária oferta de ensino remoto diante da pandemia do Covid-19, se mobilizou politicamente construindo fóruns de participação sindical, buscando uma unidade combativa e autônoma da categoria. De abordagem qualitativa, se fundamenta na produção da Rede de Pesquisadores sobre Associativismo e Sindicalismo dos Trabalhadores em Educação (Rede ASTE) como Ferreira Junior (1998, 2006a, 2006b, 2008), Bauer (2015), Bauer e Dantas (2018), Robson Silva (2013), tendo em seu percurso metodológico a sustentação em entrevistas realizadas com professores procurando compreender a constituição de permanências e rupturas temporais que possuem eco ou reverberam na atualidade do SINDEDUCAÇÃO. Assim, os resultados constituem aspectos da história do tempo presente, trazendo relevo ao contexto histórico atual por meio da investigação da construção do passado e dos seus usos políticos, registrando na história da educação, os esforços dos professores da rede pública ludovicense na organização política e sindical, identificando que apesar das tentativas, não houve uma unificação das oposições, mas espera-se que a chapa eleita, constituída de diversos coletivos, estabeleça objetivos comuns mediados por práticas pedagógicas e políticas que fortaleça a entidade e garanta a formação política dos professores.

Background: The aim of this research was to study the effect of air-abrasive treatment of dentin on the chemical composition of its surface and the adhesion strength of 2 self-etching adhesive systems (AS). Methods and Results:	Powders based on aluminum oxide (Al2O3) (27µm) (KaVo, Biberach, Germany), sodium bicarbonate (NaHCO3) (40µm) (AIR-FlOW Classic Comfort, EMS, Nyon, Switzerland), and erythritol (14µm) (AIR-FLOW Plus, EMS, Nyon, Switzerland) were used for the air-abrasive treatment of adhesive surfaces. Bonding steps were carried out with Single Bond Universal (SBU) (3M ESPE, USA) and Bond Force 2 (BF2) (Toquyama, Japan). The adhesion strength of composite to dentin was evaluated on 80 samples prepared in accordance with the Ultradent Shear Bond Strength test. All samples were divided into 4 groups depending on the method of dentin surface processing. In the samples of Group 1 (n=20), aluminum oxide was used for the air-abrasive treatment of dentin. In Group 2 (n=20) and Group 3 (n=20), samples were treated using powders based on sodium bicarbonate and erythritol, respectively. Group 4 (control, n=20) included tooth samples in which the dentin surface was not air-abraded after preparation with carbide burs. Then, each group was divided into 2 subgroups (Sub-A and Sub-B) depending on the type of adhesive system used. Adhesive resin was applied and polymerized in accordance with the manufacturer’s instructions. Single Bond Universal (SBU) was used for the samples of Sub-A, and Bond Force 2 (BF2) (Toquyama, Japan) was used for the samples of Sub-B. Scanning electron microscopy and determining the surface elemental composition of samples were carried out on an SEM-EVO MA 10 (Carl Zeiss) and energy dispersive X-ray spectrometer with EDS Aztec Energy Advanced X-Act (Oxford Instruments). It was concluded that air-abrasive treatment of the dentin surface does not enhance the adhesion strength of composite material when using self-etch AS. Also, it was noted that the pH level of self-etch AS is not a crucial feature in determining the strength of the filling-tooth interface. The resulting variations in the elemental composition of dentin surface after air-abrasion with various mixtures and their effect on the efficacy of the different AS require further in vitro studies.
