A Comparative Study of University and Private Language Institute EFL Teachers' Familiarity with and Classroom Practicality Perceptions of Dynamic Assessment
Authors:   Shahid Beheshti University, Nushi Musa , Momeni Ali ,   Shahid Beheshti University
Published: October 2022

The widespread prevalence of dynamic tools to assess English language achievement has led to burgeoning research on exploring different aspects of teachers' beliefs toward Dynamic Assessment (DA). In the educational system of Iran, experts and researchers who have undergone second language education may verify that there is very little, if any, attention given to the perceptions held by instructors and teachers regarding Dynamic Assessment (DA). In an attempt to remedy this gap, the current study aimed to investigate the familiarity with DA of Iranian EFL teachers working in two educational settings (e.g., language institutes and universities). The study also set out to explore the teachers' attitudes toward the practicality of DA in the two settings. To address the research questions, a sequential explanatory mixed methods design was employed. The instruments of this study comprised a questionnaire and an Email interview with 12 ELT assessment experts in order to have their interpretations of the research findings. The results of the t-tests showed no significant difference between the two groups of teachers in terms of their familiarity with DA and their attitudes toward the practicality of DA in the two contexts. In addition, content analysis of the Email interview data revealed that the ELT assessment experts' primary arguments for the insignificant difference between the two groups in terms of the two variables related to the fact that DA has remained at the theoretical level, that there is a lack of teacher training in DA and the strict rules of Iran's educational system which prohibit teachers from applying DA principles and procedures in their classes. The implications of the findings for teacher education, materials development as well as for program administrators, EFL teachers, and learners will be discussed.

Considering the significance of corrective feedback to improve language learners’ speaking performance, the current study aimed to examine the impact of direct oral corrective feedback on speaking accuracy and motivation to speak of Iranian EFL learners. To this end, 46 EFL learners who were preparing themselves for the IELTS exam, both male and female, were invited to participate in this study. Having homogenized the participants through the Oxford Placement Test, the researchers divided them into one experimental and one control group. As to the pretest, a valid IELTS speaking test and a motivation to speak questionnaire were administered to both groups in order to measure the learners’ speaking ability and motivation to speak level. The experimental group received direct oral corrective feedback on their speaking performance for 15 sessions. The control group did not receive any special kind of corrective feedback. A posttest, equivalent to the pretest, was administered after the end of the treatment sessions to both groups to find whether direct oral corrective feedback affected the learners’ speaking accuracy and motivation to speak. The results of statistical data analysis indicated that the experimental group significantly outperformed the control group on both speaking accuracy, and motivation to speak. Pedagogical implications are suggested to language teachers and teacher trainers.

Published: October 2022

This study presents the execution of an iterative technique suggested by Temimi and Ansari (TA) method to approximate solutions to a boundary value problem of a 4th-order nonlinear integro-differential equation (4th-ONIDE) of the type Kirchhoff which appears in the study of transverse vibration of hinged shafts. This problem is difficult to solve because there is a non-linear term under the integral sign, however, a number of authors have suggested iterative methods for solving this type of equation. The solution is obtained as a series that merges with the exact solution. Two examples are solved by TA method, the results showed that the proposed technique was effective, accurate, and reliable. Also, for greater reliability, the approximate solutions were compared with the classic Runge-Kutta method (RK4M) where good agreements were observed. For more accuracy the maximum error remainder was found, and the absolute error was computed between the semi-analytical method and the numerical method RK4M.  Mathematica® 11 was used as a program for calculations.

Published: October 2022

In this study, an efficient photocatalyst for water splitting was developed. The Cr2O3 and TiO2 nanoparticles (Cr2O3-TNPs) nanocomposite with (Chitosan extract) was created using ecologically friendly methods, such as the impregnation technique as TiO2 exhibits nano spherical (TNPs) shape structure. According to the researchers, this nanocomposite material enhanced its ability to absorb ultraviolet light while also speeding up the recombination of photogenerated electrons and holes. The TNPs and prepared Cr2O3-TNPs were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), energy dispersive x-ray spectroscopy (EDX), and UV-visible absorbance. The XRD of TNPs showed a Tetragonal phase with 8.9 nm of average crystallite size and 14.2 nm for nanocomposite. FE-SEM images showed that the average particle size in the range of (12.5-57.5) nm and UV-VIS absorbance has energy gap of 3.8 eV, while the energy gap of Cr2O3-TNPs is 2.8 eV. It was found that the performance of photocatalysts of the nanocomposite for hydrogen generation was superior. It gave the highest rate of hydrogen production (3.6) ml at 80 min when exposed to ultraviolet light. Moreover, the nanocomposite revealed high H2 production rate under ultraviolt light irradiation (λ < 400 nm). The Cr2O3-TNps have high photocatalytic effectiveness due to their wide ultraviolt light photoresponse range and excellent separation of photogenerated electrons and holes.
New Species and Combinations in the Cerrenaceae (Polyporales, Basidiomycota)
Authors: Nakasone Karen , Ortiz-Santana Beatriz
Published: October 2022

The classification and taxonomy of the Polyporales have undergone tremendous change and made significant progress in the last ten years. A case in point is the Cerrenaceae that was created just five years earlier. This is one of the smaller, lesser-known families with just five recognized genera and is well-defined and supported by phylogenetic analyses but difficult to characterize by morphology. Some genera and species in the Cerrenaceae display a range in basidiome habit, hymenophore configuration, and hyphal system that overlap with species from other families in the Polyporales and Agaricales. In this study, we clarify the morphological features that distinguish genera in the Cerrenaceae by conducting taxonomic studies in Irpiciporus, Pseudolagarobasidium, Pseudospongipellis, and Radulodon and presenting keys to the accepted species. Generic descriptions for Irpiciporus and Radulodon are revised. Two new taxa are described and illustrated, namely, Irpiciporus rajchenbergii from Brazil and Pseudospongipellis tomsovskyi from southwestern United States. In addition, four new combinations are proposed — Irpiciporus africanus, I. decolorans, I. revolubilis, and Pseudolagarobasidium cirrhatinum. Radulodon acacia, from India, is placed in synonymy under Pseudolagarobasidium acaciicola, and Irpiciporus noharae, from Japan, is confirmed to be a synonym of Lopharia mirabilis.

Great progress has been made in recent years on taxonomy of brown rot polypores based on phylogenetical evidence, mainly Daeadalea within Fomitopsidaceae. However, the relations within the Fomitopsidaceae family remain unresolved. Some neotropical species of Daedalea were never included in molecular phylogenetic analyses, such as D. aethalodes, D. ryvardeniana, and south American specimens of D. modesta. To clarify the relationships of those species within Daedalea we carried out molecular phylogenetic analyses based on five molecular markers (ITS, nLSU, nSSU, RPB2, and TEF-1). Daedalea s. s. was recovered as a strongly supported clade including most species, however, Daedalea radiata grouped with Rodofomitopsis. A new neotropical species, Daedalea rajchenbergiana sp. nov., was described based on molecular phylogeny, morphology, and distribution evidence. The placement of Daedalea aethalodes, D. ryvardeniana, and D. rajchenbergiana sp. nov. within Daedalea s. s. was confirmed.

Uso de la secuenciación de segunda generación (NGS) para descubrir la diversidad de hongos degradadores de la madera en los bosques Andino Patagónicos
Authors: Molina Lucia , Pildain María Belén
Published: October 2022

Los hongos son los principales degradadores de la madera en los ecosistemas boscosos, contribuyendo significativamente al ciclo global del carbono. Los enfoques metagenómicos basados en un amplicón específico (metabarcoding) constituyen una herramienta poderosa para su prospección y estudio. El objetivo principal de este estudio fue caracterizar a través de secuenciación de segunda generación (NGS), comunidades de hongos degradadores en la albura de dos especies de Nothofagus de los bosques del norte de la Patagonia, para evaluar patrones de diversidad en sitios, estaciones, hospedadores, compartimentos del árbol y condiciones de salud, como una contribución a la autoecología de las especies de este género. Nuestro estudio comprendió tres pasos metodológicos principales: (i) muestreo de madera de árboles vivos sanos y enfermos de las especies forestales N. dombeyii y N. pumilio; (ii) extracción de ADN, amplificación y secuenciación de la región ITS1 en la plataforma MiSeq Illumina, (iii) procesamiento de lecturas y extracción de datos de los órdenes Polyporales e Hymenochaetales y (iv) análisis de datos e interpretación. Se obtuvieron un total de 35 unidades taxonómicas (variantes de secuencia de amplicón -ASV-), las cuales fueron asignadas a 23 géneros de hongos putativos en 15 familias. Postia pelliculosa fue la especie detectada con mayor frecuencia en el estudio. El hospedador fue el factor más fuerte entre las variables estudiadas en cuanto a su efecto sobre la estructura y la composición de la comunidad fúngica analizada. Para N. dombeyi, que se distribuye en una amplia gama de condiciones climáticas, el sitio fue el modelador más fuerte de sus comunidades, mientras que para N. pumilio se observó una mayor susceptibilidad a los cambios de temperatura y estacionalidad, que son, ciertamente, factores relevantes para la conservación de los bosques en el actual escenario de cambio climático. Este es el primer estudio que utiliza NGS como una estrategia rápida y a gran escala para descubrir la diversidad de hongos que degradan la madera en los bosques templados de Patagonia.

Los hongos xilófagos atacan frecuentemente ejemplares del arbolado urbano descomponiendo su madera. Esto afecta negativamente la estabilidad y resistencia al quiebre, poniendo en riesgo a la población y sus bienes. Durante un relevamiento de las pudriciones presentes en el arbolado de la ciudad de La Plata, fueron observados ejemplares de Melia azedarach (Meliaceae) con evidencias de pudrición blanca en duramen expuesto. El objetivo del trabajo fue identificar al hongo responsable de esta pudrición y analizar las alteraciones anatómicas y químicas que causa en el leño. Se examinaron muestras de duramen con evidencias de pudrición blanca en estadios intermedio y avanzado extraídas de fuste y rama, respectivamente. Los aislamientos fúngicos fueron obtenidos de secciones de madera sembradas en agar malta con antibiótico y fungicida. La identificación fue llevada a cabo a partir de las características de las colonias y confirmada mediante técnicas moleculares. Los estudios anatómicos fueron realizados con microscopios estereoscópico, óptico y electrónico de barrido, y los análisis químicos mediante química húmeda y espectroscopía infrarroja transformada de Fourier (FT-IR). Phlebia brevispora (Basidiomycota, Polyporales) fue la única especie xilófaga aislada del material. Las alteraciones anatómicas registradas permitieron diagnosticar pudrición blanca simultánea en fuste y coexistencia de pudrición blanca simultánea y selectiva en rama. Mediante química húmeda fueron determinados incrementos relativos en el tenor de lignina y extraíbles lipofílicos, y disminuciones en el porcentaje de los extraíbles hidrofílicos en las muestras de ambos estadios de degradación (rama y fuste); la disminución del tenor de celulosa sólo fue identificada en rama. El FT-IR reveló el ataque a la celulosa y la lignina. Si bien existe información previa de la presencia P. brevispora en árboles en pie, el presente hallazgo constituye el primer registro para la Argentina, mientras que la interacción P. brevispora - Melia azedarach es reportada por primera vez en esta contribución.

Capillary pressure is an important parameter in both petrophysical and geological studies. It is a function of different porous media properties, in special, the pore structure of the rock. Mercury Injection Capillary Pressure (MICP) analysis is a consistent methodology for determining different petrophysical properties including porosity, and pore throat distribution. The matrix permeability is dependent on the pore size distribution but is not directly measured from MICP tests. In this work, we consider distinct parameters derived from MICP tests for the prediction of permeability by following a machine learning based approach. Firstly, a vast range of MICP test results (246 samples) related to tight sandstones is gathered with a permeability range of 0.001 to 70 millidarcy. After quality checking of dataset, different theoretical permeability models are tested on the dataset and the results are analyzed. Also, different features related to the pore throat characteristics of rock is analyzed and the best characteristics are selected for the input variables to the machine learning model. The Support Vector Regression (SVR) approach is proposed with the Radial Basis Function (RBF) kernel for the prediction of rock permeability from MICP tests. A Particle Swarm Optimization (PSO) is applied for optimization of the model meta parameters in the validation process to avoid over or underfitting. The training of the model is carried out with random selection of 80% of samples while other points are applied for testing of the model. The data analysis on the correlation between rock permeability and parameters of capillary pressure is studied and showed that using pore throat radius corresponding to saturation range of 0.4-0.8 and the median capillary pressure values obtained from the capillary pressure curves is suitable to be used as input features of the SVM model. Also, the porosity and Winland equation was considered as input features due to their acceptable correlation with the rock permeability. The results showed that the implemented SVM-PSO model can acceptably predict the experimentally measured permeability values with R2 rate of over 0.88 for training and testing datasets. This work represents an analysis of the relationship of capillary pressure curve specifications with permeability on a large MICP dataset, especially focused on tight sandstone rocks. The analysis provided new statistical and physics-based features with the highest correlations with the rock permeability that helped in significant improvement of the SVM-PSO prediction results.
Deep-Directional Resistivity Ranging for Near-Parallel Cased Well in Scenarios Either Vertical or Horizontal to Formation Layers
Authors:   Schlumberger, Chen Yong-Hua , Omar Saad ,   Schlumberger, Liang Lin ,   Schlumberger, Salim Diogo ,   Schlumberger
Published: October 2022

As additional wells are being drilled worldwide to develop oil and gas reserves, technologies for detecting an existing well and determining its relative distance and azimuthal orientation from a new well being drilled are extremely important. These technologies are essential for various applications such as collision avoidance, well interception, among others. Ultradeep harmonic anisotropic attenuation (UHAA) measurements are very sensitive to the proximity of an existing near-parallel metallically cased well or a conductive fluid-filled borehole. These UHAA measurements are based on the ratio of the second harmonic coupling voltages between the transversely polarized magnetic dipoles of the deep-directional resistivity tools. This paper presents ranging workflows to interpret the UHAA measurements and determine the distance between an existing cased well and the well being drilled for conditions in which the two wellbores are either vertical or horizontal with respect to the formation layers. The interpreted distance is also plotted together with the measured second harmonic angle to show the azimuthal orientation of the cased well in relation to the deep-directional resistivity tool. For the vertical well scenario, the UHAA measurements are primarily affected by the casing and the formation anisotropy, and the ranging can be performed by means of interpolating the UHAA data in a simulated tool response table. For nonparallel wells, a first-order correction to the interpreted distance is introduced to account for the relative wellbore inclination and azimuthal orientation derived from the well trajectories. Examples of the interpreted ranging results will be presented for synthetic data and field cases. For the horizontal well scenario, the formation layers also become major contributors to the UHAA response and significantly interfere with and limit the detection of the nearby metallically cased well. This paper presents a method to correct the UHAA measurement data by subtracting the simulated UHAA tool response in the formation layers without the cased well. The correction method is shown to significantly increase the detection distance between the cased well and the new well being drilled. The profile of the formation layers can be assumed known or roughly known because there is already an existing near-parallel cased well that might have been logged previously. It is also possible to reconstruct these formation layers from the measurements made by a shallower resistivity measurement tool operating at higher frequencies with a shorter transmitter-receiver spacing. Numerical examples will be presented to demonstrate the effectiveness of the proposed ranging interpretation method for the horizontal wells.

The scope of this paper is to illustrate the successful application of the Advanced Mud Gas (AMG) analysis in oil rim development wells, in a large fault block reservoir offshore Brunei Darussalam, operated by Brunei Shell Petroleum (BSP). Developing thin oil rims is challenging as gas and water breakthrough can be very common and therefore the need to have an accurate fluid type identification is crucial for the subsequent completion. In this field, pressure depletion and wellbore instability posed serious concerns about the effectiveness of the traditional density-neutron tool to reliably identify the fluid phase and the associated risk of losing the radioactive source in the hole. Eventually, BSP opted to run the AMG technology as an alternative solution to mitigate the risk and acquire continuous, accurate information about the type of fluid. The AMG is an advanced mud gas system providing continuous PVT-like composition in the C1-C5 range. The gas ratio analysis allows inferring the fluid type in the reservoir during drilling. The continuous data nature gives a complete fluid profile along the well. Historical data from the same field, including AMG and PVT samples, was used to calibrate a numerical model for fluid type characterization. A comprehensive interpretation workflow was built and implemented during drilling, that also accounted for the potential effect of pressure depletion on the fluid composition. AMG was successfully run in two side-track sections, in place of the Density-Neutron tool and delivered accurate fluid type in the crossed reservoirs and helped designing an effective completion plan. Further, the use of the AMG technology had a tremendous impact during the execution of the first sidetrack section, where the bottom hole drilling assembly was lost in the hole, to prevent serious environmental incident and reduce operational cost. The integration of multiple data sources, in the same platform, facilitated interpretation models based on numerical determinants using a model calibration from the field with similar reservoir conditions. AMG, eventually, was selected as the primary tool for well logging in this field as an industry proven technology for fluid type identification.

We apply our novel automated image interpretation workflow to Brazilian pre-salt ultrasonic borehole image data. We obtain an immediate, un-biased classification of the full data, requiring no further input data beyond the borehole image itself. This interactive solution combines statistical and deep learning algorithms for image embedding to provide data-driven, multi-purpose borehole image interpretation. Borehole images are a source of important information for building static reservoir models. Textures observed in these high-resolution well logs are the results of and provide insights into the different processes that have occurred: from the moment of the deposition until the image acquisition. Each field, reservoir, well, and interval has a unique textural assemblage, consequence of its own depositional facies, diagenetic processes, geomechanics and wellbore conditions or well intervention and completion. Efforts to automate facies interpretation in our industry often rely on applying supervised machine learning models. These supervised algorithms are restricted to executing very specific tasks, based on extensive amounts of consistently labeled data. In the example of depositional geological classification, generating labeled data can be a complex and extensive task, subject to interpreters’ experience – resulting in a low human performance benchmark. The solution proposed here comprises a sequence of five steps: • Prepare data; • Apply a first embedding step using statisticalmethods or convolutional autoencoders; • Apply PCA or t-SNE techniques as the secondembedding step; • Perform manual or automatic clustering; • Finally, assign a facies class to each textural group. This paper discusses applying this innovative workflow to acoustic borehole images of pre-salt carbonates from the Santos basin. Various preprocessing and embedding options were tested and compared to the geological core interpretation. Using statistics, semi-supervised t-SNE and k-means clustering methods, we divide the data into textural groups and describe these groups according to their distinct geological, diagenetic or geomechanical characteristics. With this new approach, facies are defined based solely on borehole image logs in a fast, consistent and less user-biased form. Ultimately, our innovative workflow allows us to not only gain insights into the depositional, geological and geomechanical processes and their correlation with the pre-salt carbonates reservoir quality, but to establish a more efficient, reliable method for borehole image interpretation in general.

Wewenang pemerintah yang cukup luas dalam pengelolaan keuangan negara untuk penanganan pandemi Covid-19, yang semula diatur berdasarkan Perppu tentang Kebijakan Keuangan Negara dan Stabilitas Sistem Keuangan untuk Penanganan Pandemi Covid-19 dan/atau dalam Rangka Menghadapi Ancaman yang Membahayakan Perekonomian Nasional dan/atau Stabilitas Sistem Keuangan kemudian ditetapkan dengan undang-undang berpotensi menimbulkan kerugian warga negara atau badan hukum perdata. Namun, terdapat pasal yang dapat dapat memicu persoalan hukum karena memberi imunitas terhadap segala tindakan Pemerintah yang diambil berdasarkan UU ini, sehingga tidak dapat menjadi objek gugatan kepada PTUN. Penelitian dengan metode normatif, melalui pendekatan perundang-undangan dan konseptual ini bertujuan untuk, pertama, menganalisis politik hukum pengaturan imunitas terhadap segala keputusan dan/atau tindakan pemerintah dalam pengelolaan keuangan negara untuk penanganan pandemi Covid-19; kedua, merumuskan alternatif pelindungan hukum bagi subjek hukum yang berpotensi dirugikan atas tindakan dan/atau keputusan pemerintah dalam pengelolaan keuangan negara untuk penanganan pandemi Covid-19. Penelitian ini menyimpulkan salah satunya pelindungan hukum dapat terakomodasi secara preventif melalui pengawasan administrasi, pengesahan dan persetujuan, serta keterbukaan pemerintah; dan secara represif melalui mekanisme upaya administratif atau laporan ke Ombudsman RI

Land filling is one of the most common methods of disposing of solid waste all over the world, however, with constantly increasing waste volumes and land scarcity, waste diversion and recovery are more likely the best answer to these concerns. This research paper presents an estimation of the diversion impact on the required land area and on the lifespan of a technical landfill centre (TLC) in Constantine, Algeria. Our methodology consists in drawing up three scenarios of operation of TLC, over a period of 15 years, with each scenario, applying a different waste diversion rate, results show that: waste diversion reduces land consumption and increases the TLC's lifespan in all three scenarios but diverting for composting is the most efficient one.
Soviet Medical Internationalism amid Destalinization, 1953–1958
Authors: Michaels Paula A.
Published: October 2022

This article reconstructs the story of the Soviet Union’s medical internationalism amid the early years of destalinization, when it re-engaged more actively in the global health community. How did the USSR attempt to leverage medicine as a tool of soft power in both multilateral and bilateral relations? Based on records of the USSR Ministry of Health and the Medical Workers Union, as well as newspapers and other published sources, it analyzes what destalinization meant for physicians and public health administrators who sought greater exchange with and connection to their colleagues abroad. A widening web of interconnections in this transitional period paved the way to greater integration in a global medical community. Soviet medical and health professionals nurtured international relationships with a range of strategies, expectations, and aspirations. They used these opportunities to learn, and also to speak back to their superiors and to shape the trajectories of domestic research agendas.

This paper studies the materials, tools, and artisans recorded in the Posagongshin bok'undogam ŭigwe to understand the significance of Iship kongshin hoemaengch’u in the history of crafts in Korea. Iship kongshin hoemaengch’u is an elegantly decorated twenty-four-meter-long scroll made for King Sukjong, containing oaths of allegiance to the king in a time of political upheaval and reforms, and the names of 489 meritorious subjects. In making this scroll, a special directorate was set up and several government offices, including the Directorate of Fabrics, provided materials and tools, and artisans of various fields were assigned. The long fabric was made in the traditional way by cooperation of yŏnsajang(thread artisan), badijang(badi for loom artisan) and ch’ojang(silk artisan). The attaching layers were made by pulling the wooden frame tight with bamboo trees in the spacious floor of the Ministry of War building at Gyeongdeokgung Palace. The scroll was bordered with brilliant silk, and was fitted with jade caps made by okjang(jade artisan) from Pyeongando Province and a cord made by tahoejang(threaded cord artisan) was attached. Court painters drew guidelines for writings and official scribes wrote the oaths and names in regular script. Conclusively, Iship kongshin hoemaengch’u shows the best of court craftsmanship made in cooperation between skilled artisans of specialized fields, using the materials of highest quality to manifest King Sukjong’s will to assert his authority.
