Learner Use of Photo-Editing Software in Classes
Authors: Grandon Marcus
Published: August 2020

In this classroom research project, 27 learners in three courses at one university use professional-level, photo-editing software to create and remix images in language lessons. The overarching purpose of this study is to deepen understanding of what actually occurs in lessons through the use of materials. I delivered these lessons with a Content and Language Integrated Learning approach in which English was used for both the teaching and learning of not only lesson content but also language (Coyle, Hood, & Marsh, 2010). Data include emails written by the learners to describe and evaluate their experiences with the software, digital artifacts created during the courses, and my research journal. Qualitative analysis is conducted in a grounded fashion using iterative coding (Saldaña, 2013) to identify emergent themes from a research perspective of materials use. Learners appear to demonstrate self-direction and creativity in highly personal ways throughout the lessons.
本授業調査研究では、ある大学における３つのコースにおいて、27人の学習者が専門家レベルの写真編集ソフトウェアを使用し、語学の授業内で画像の作成およびリミックスを行った。この研究の包括的な目的は、学習者にこれら諸教材を用いることにより授業中に起こることを深く理解させることである。本研究指導者は、授業内容だけでなく言語教育と学習の両方に英語を使用するContent and Language Integrated Learning（内容言語統合型学習）によるアプローチを用いた (Coyle, Hood, & Marsh, 2010)。データには、ソフトウェアを用いた経験を説明および評価するために学習者が書いた電子メール、コース中に作成したデジタルアーティファクト、および指導者が所持する研究ジャーナルを含む。質的分析には、教材使用の研究展望から生まれてくるテーマを特定するために反復コーディング (Saldaña, 2013)を用いた。学生はレッスンを通じ、自分なりのやり方で自己主導性と創造性を示した。
Teachers’ Beliefs About Classroom-Based Assessment
Authors: Murray Adam
Published: August 2020

In this paper, we report on the early stages of the development of the Classroom-Based Assessment Self-Efficacy Scale (CBA-SES), an instrument designed to examine how Japanese Teachers of English (JTEs) feel about classroom-based assessment. The questionnaire (31 items) consists of three sections: (a) teachers’ beliefs, (b) teachers’ self-efficacy, and (c) their own teaching practice. We pilot tested this instrument with 30 JTEs in order to assess its appropriateness and to get a better understanding of the tendencies and characteristics of JTEs. We found that the belief statements are suitable, but revision along with additional statements will be needed for self-efficacy and practice for the next version of the instrument. The participants believed language tests should resemble real-life language use. Notably, they were able to make such tests and were doing so in their teaching contexts. They also felt that effective feedback and the use of clear learning targets were important.
教室内評価の重要性が増しつつある中、日本人英語教師がそのような評価に対してどのように感じ、また実践しているのかを探るため、本研究では教師の自己評価を測る実験的な質問紙を作成し、現役の英語教師に回答を依頼した。質問紙は、信条（Belief）、自己効力感（Self-efficacy）、実践（Practice）の３セクションから成り、それぞれ、「評価はこうあるべき」、「このような評価を行うことができる」、「このような評価を実際に行っている」という側面の自己評価を測定した。その結果、信条に関する項目は適切であったが、自己効力感と実践に関するものについては次の本格的な実施に向けて修正や追加が必要であることが判明した。殆どの回答者が現実の言語使用を反映したテストの作成が重要と考え実践しようとしていること、また、明確な指導目標の設定と効果的なフィードバックの重要性を感じていることは注目すべきであった。
TOEIC Listening and Reading Test and Overall English Ability
Authors: Kanzaki Masaya
Published: August 2020

The Test of English for International Communication (TOEIC) covers the four skill areas of listening, reading, speaking, and writing. This study investigates the correlations between the four skill scores of the TOEIC to determine the practicality of using the listening and reading scores to gauge overall English ability. The study was conducted over a 3-year period, during which data were collected from 260 university students. The four skill scores were significantly correlated with each other, with the highest correlation between the listening and reading scores (r = .73), and the lowest between the listening and writing scores (r = .52). The combined listening and reading scores were strongly correlated to the overall scores (r = .95), which suggests that the TOEIC Listening and Reading test scores can be a good proxy for overall scores on the TOEIC.
The Test of English for International Communication（TOEIC）は、リスニング、リーディング、スピーキング、ライティングの4つの技能領域を対象にしている。本研究では、リスニングとリーディングの得点を総合的な英語力の判定に使うことの実用性を判定するため、TOEICの4技能得点間の相関を調べた。本研究は3年間に渡って行われ、260名の大学生からデータを集めた。4技能の得点間にはそれぞれ有意な相関があり、一番高い相関はリスニングとリーディングの得点間（r = .73）、一番低い相関はリスニングとライティングの得点間（r = .52）であった。リスニングとリーディングの合計点は、総合点と強い相関があり、それはTOEIC Listening and Readingテストの得点がTOEICの総合点の良い代替指標になり得ることを示唆している。

Published: August 2020

The prevalence of overweight and obesity among women in Uzbekistan is 31.7 %. There is an annual increase in people with obesity. The facts of the negative impact of fat mass on the hormonal system and, as a result, a decrease in fertility in women are not in doubt. The purpose of this study was to evaluate the results of Metformin use in overweight and obese women of reproductive age. The study included 45 women of reproductive age who could not reduce weight with diet therapy. All patients were divided into three groups: group 1-planning pregnancy (n = 15), group 2 – having abnormal weight gain after childbirth (n = 15), group 3 – having overweight and obesity not related to pregnancy and childbirth (n = 15). Weight loss while taking Metformin increases fertility and should be performed in obese women as pre-gravidar training.

Published: August 2020

This study is undertaken to critically underline the role of government in managing the conflicts, most notably the federal government of Somalia. The undergone research also discusses the prolonged Somali conflict and options for the conflict resolutions with the available roles for the federal government of Somalia during any conflict. The study finds that the previous conflict resolutions of Somalia were unsuccessful as most of the conflicts exist till today. The role of federal government is limited to the Somali peace processes and conferences with the ethnic motivated perceptions. As a result, the study concludes that the federal government of Somalia is perceived by the public as involved in the conflicts. Thus, in order to eliminate the prolonged Somali conflict, it is suggested to formulate strong federal agencies to prevent any possible conflict in future, besides employing community based conflict resolution mechanisms.

Published: August 2020

The study evaluates the overall situation of Vietnam’s fisheries exports and uses the Global Simulation Analysis of Industry-Level Trade Policy model (the GSIM model) to predict the impact of the CPTPP agreement on Vietnam’s fisheries exports to the CPTPP members. It is forecasted that the CPTPP has positive effects on Vietnam’s fisheries exports. One of those is that it is promising for Vietnamese producers/exporters to access Mexico, which is a large market in the southern portion of North America. In addition, Vietnam has the advantage to continue increasing export earnings to the Japanese market after the CPTPP takes effect. By sub-sector, all sub-sectors have a positive impact on consumers/importers as well as producers/exporters. In terms of export value, all sub-sectors have increased export value, especially the Crustaceans, molluscs and other aquatic invertebrates, prepared or preserved (HS1605) export to Japan and the fish fillets and other fish meat (whether or not minced), fresh, chilled or frozen (HS0304) has significant export rise to Mexico. Nevertheless, the reduction of import tax revenues reduces the welfare of the fisheries sector.

CONVERSION STRATEGIES FOR DUTCH PRIMARY SCHOOLS: PRACTICE AND REFINEMENT
Authors: Broekhuizen Dolf , Arkesteijn Monique , Jong Peter de , van Nieuwamerongen Frido van
Published: August 2020

Handbooks on strategic real estate management are generally based on four strategies for functional adjustment of the building: conversion, expansion, renovation and adaptive reuse. And on a strategic level, this classification in adjustment strategies does work for real estate in general. But when looking at Dutch primary schools as a specific type of real estate, reality can be and is more nuanced. Other accommodation strategies came to the fore in a study into the spatial adaptation of primary schools and children’s centres in the Netherlands. An analysis of 100 school buildings studied in the Atlas of School Building (published in Dutch as Scholenbouwatlas) revealed that nine main strategies were prevalent in practice. This refinement of the strategies fits (better) with integrated conversion actions of primary schools in which several aspects are solved together. In the following article these strategies are analysed and discussed in a theoretical context. The conclusion of the analyses is that the existing general models in the strategic handling of the building stock in the case of specific real estate of primary schools can be refined.

Published: August 2020

The Egyptian construction industry suffers from severe delays and cost overruns. Rework is a prime cause of this challenge. Therefore, the objective of this study to identify the root causes of rework for Egyptian construction projects and their impact on the project duration and cost. An extensive literature review has been done to identify the most common factors affecting rework. Hence, eighty-seven factors were identified and categorised into ten groups. Structured interview technique was adopted to get the opinions of 67 Egyptian construct professionals for nineteen different construction projects. Total Importance Index of Rework Impact (T.I.I.R.I%) was used to analyse and rank rework factors. Accordingly, the most critical five rework factors are economic situation for the country, schedule compression, design changes, specifications change, and inadequate feasibility study. Based on the survey results, the project stakeholders should consider the critical rework factors during the planning stage and before the project execution, to eliminate or reduce the occurrence and impact of rework causes and to improve the performance of the projects. This paper provides state of the art for rework causes and their effects on construction projects performance, and it can be beneficial for both practitioners and researchers for future work.
Evolution of an Asteroid Family under YORP, Yarkovsky, and Collisions
Authors: Marzari Francesco , Rossi Alessandro , Golubov Oleksiy , Scheeres Daniel J.
Published: August 2020

Any population of asteroids, like asteroid families, will disperse in semimajor axis due to the Yarkovsky effect. The amount of drift is modulated by the asteroid spin state evolution, which determines the balance between the diurnal and seasonal Yarkovsky forces. The asteroid’s spin state is, in turn, controlled in part by the Yarkovsky–O’Keefe–Radzievskii–Paddack (YORP) effect. The otherwise smooth evolution of an asteroid can be abruptly altered by collisions, which can cause impulsive changes in the spin state and can move the asteroid onto a different YORP track. In addition, collisions may also alter the YORP parameters by changing the superficial features and overall shape of the asteroid. Thus, the coupling between YORP and Yarkovsky is also strongly affected by the impact history of each body. To investigate this coupling, we developed a statistical code modeling the time evolution of semimajor axis under YORP–Yarkovsky coupling. It includes the contributions of NYORP (normal YORP), TYORP (tangential YORP), and collisions whose effects are deterministically calculated and not added in a statistical way. We find that both collisions and TYORP increase the dispersion of a family in semimajor axis by making the spin axis evolution less smooth and regular. We show that the evolution of a family’s structure with time is complex and collisions randomize the YORP evolution. In our test families, we do not observe the formation of a “YORP-eye” in the semimajor axis versus diameter distribution, even after a long period of time. If present, the “YORP-eye” might be a relic of an initial ejection velocity pattern of the collisional fragments.

Published: August 2020

This report provides a description of Primula sunhangii from the Shennongjia Forestry District, Hubei Province in Central China, which is categorized as a new species of the primrose family. Primula sunhangii is morphologically similar to P. involucrata Wall. ex Duby in terms of its simple umbel, efarinose, and prolonged bracts. However, P. sunhangii is distinguished by its glabrous sepal, short petiole (compare with blade) and cylindrical calyx and capsule. Molecular phylogenetic analysis based on nuclear and cpDNA genes demonstrates that P. sunhangii and P. involucrata are closely related. Combining genetic and morphological data, the recognition of P. sunhangii as a unique new species is supported.
A novelty in Ceratozamia (Zamiaceae, Cycadales) from the Sierra Madre del Sur, Mexico: biogeographic and morphological patterns, DNA barcoding and phenology

Published: August 2020

Ceratozamia is a genus of cycads occurring in eastern Mexico and Central America. In this study, we describe a new species from the Pacific region of Mexico in Guerrero state. This locality represents the most northwestern Mexico distribution for the genus. We focus the comparison of this species with the most geographically proximate and phenotypically relevant lineages for this taxon. We followed an integrative taxonomy approach to evaluate the classification of these species, including geographic location, morphology, DNA barcoding and phenology as primary sources of systematic data. Within the morphological dataset, reproductive structures are described in detail and new characters are proposed for microsporophylls. The comparative morphology of these structures facilitated the elucidation of differences in forms and species for identification. The two chosen DNA barcoding markers – namely, the chloroplast genome coding region matK and the nuclear ribosomal internal transcribed spacer (ITS) region – had low divergence, allowing only 61% of species identification, suggesting slow molecular evolutionary rates. Besides employing these three basic sources of evidence, we introduced phenology as additional information for species circumscription. In addition, this work includes a brief review of the genus at the species-level. This is therefore the most recent review for Ceratozamia across its full geographic range (latitudinal and elevational). Overall, this work further contributes to a comprehensive framework for systematic studies in Mexican cycads.
Rediscovery and taxonomic placement of Solanum polyphyllum Phil. (Solanaceae), a narrow endemic from the Chilean Atacama Desert
Authors: Moreira-Muñoz Andres , Muñoz-Schick Melica
Published: August 2020

Although the original description of Solanum polyphyllum Phil. was made in 1891, this species was not seen until it was re-discovered 128 years later in 2019 in the Atacama Desert. Fruits and seeds were previously unknown and a complete description is provided here. This species was not treated in the most recent monograph of Solanum sect. Regmandra, but it should be incorporated in this section due to its glabrous, sessile and entire leaves, which are decurrent onto the stem. Morphologically, S. polyphyllum is similar to S. paposanum, also of section Regmandra, but differs in the entire leaves (against margins with 4–5 acute lobes in S. paposanum) and glabrous leaves (moderately pubescent adaxially and velutinous abaxially in S. paposanum). The rediscovery of S. polyphyllum at a new locality at the same altitudinal belt as the type, re-affirms its restricted distribution and endemism and supports a potential conservation status as an endangered species.
Le sujet non demandeur de soin et la fonction phorique. Une modalité de soin groupal
Authors: Blanquet Brigitte
Published: August 2020

Cet article propose une réflexion, à partir d’un dispositif de soin psychique groupal, ajustée à la problématique des sujets qui ne fréquentent pas les lieux de soin et que l’on retrouve en panne au cœur du socius. Ces sujets, généralement répertoriés sous le vocable de sujets non demandeurs de soin présentent une organisation psychique spécifique qui nécessite de conduire un travail de repérage rigoureux afin d’appréhender leur fonctionnement et de penser, en amont, à leur condition d’accès au soin. À l’aide d’une situation clinique retraçant deux ans de prise en charge plurifocale, l’auteur théorise un dispositif de soin institutionnel en appui sur une pratique d’accompagnement en milieu ouvert qui intègre une fonction phorique articulée à un appareil psychique groupal de suppléance.
Processus groupaux avec des enfants présentant des troubles autistiques : intersubjectivité primaire, rythmicité, rivalité
Authors: Vogt Justine
Published: August 2020

Le dispositif groupal est régulièrement proposé comme prise en charge pour des enfants présentant une symptomatologie autistique. Ce travail thérapeutique en groupe a pour but de favoriser les mises en relation et les interactions. Dans le cas des troubles autistiques, ce type de prise en charge soulève pourtant un paradoxe. L’isolement et les symptômes rencontrés dans cette pathologie interrogent sur la manière dont se constituent ces groupes. De quels types de groupe s’agit-il et quelle mobilisation psychique groupale s’opère-t-elle ? À partir d’une même séance de groupe, je propose d’étudier les processus groupaux saillants autour des formes d’intersubjectivité primaire, de la rythmicité et de la rivalité.
Résonances intergroupes et surdités groupales. L’écoute des groupes, son analyse, en musicothérapie analytique de groupe
Authors: Lecourt Édith , Julian Isabelle
Published: August 2020

Après une présentation du dispositif de musicothérapie analytique de groupe, les auteures développent un exemple clinique d’observation par l’écoute du groupe, et l’écoute de ce groupe par trois autres groupes (dans des situations d’examen) à des fins de comparaison des observations faites. Il en ressort un rapport de la qualité de ces observations au vécu, par le groupe observateur, de sa propre analyse sonore. Dans le cas présenté, l’observation la plus éloignée du vécu du groupe observé a consisté à projeter sur ce dernier une expérience d’illusion groupale, idéal auquel ce groupe d’observateurs n’avait pas pu, lui-même, avoir accès. Cette projection le rendit sourd aux difficultés et angoisses du groupe observé. Cet article se termine par une réflexion sur les rapports d’ambiguïté et d’ambivalence dans cette situation en relation avec les travaux de S. Amati-Sas et J. Bleger.
Groupe à médiation théâtre d’ombres avec des sujets déments : de l’ombre du moi à la lumière de soi
Authors: Souihi Linda , Talpin Jean-Marc
Published: August 2020

La maladie démentielle pousse le sujet à réactualiser ses expériences passées afin de combler les trous de pensée incombant aux processus de déliaison. Le démantèlement de la pensée réflexive amène la psyché à prendre appui sur une pensée archaïque ou animiste qui s’étaye sur le processus hallucinatoire utilisé comme moyen de symbolisation. L’hallucinatoire dont il est question dans cet article se réfère essentiellement à la « dynamique transformationnelle » de ce processus : sa mise en œuvre s’appuie sur une composante animiste de la pensée étayée sur la matérialisation de l’objet de médiation. La part vivante du moi peut se refléter à travers un mécanisme de personnification (propre à l’animisme) transféré sur l’objet, ici l’ombre, signe d’une re-création psychique et marque d’une subjectivité à retrouver. Le travail groupal, par les processus de déliaison/reliaison, permet au sujet dément d’avoir accès à une « réanimation psychique », à une remise en contact avec son monde interne, avec le monde externe et les autres.

Authors: Chevalier Julie , Bonnet Christian , Vollon Clarisse , Gimenez Guy
Published: August 2020

Notre article propose un confluent entre les travaux de Kaës sur les groupes internes et la polyphonie, avec les concepts d’identifications croisées et de psyché-soma de Winnicott. Ainsi nous proposons de définir le squiggle comme un jeu polyphonique mobilisant les groupes internes du patient et du clinicien au profit de l’élaboration imaginaire du corps. Pour cela, nous opérons une relecture des consultations historiques de Winnicott avec Iiro et Robin, nous permettant de montrer dans leurs traces graphiques, que nous nommons des associations corporelles spontanées, l’élaboration d’une multiplicité de bouts de corps articulés à différentes imagos inconscientes. Cette élaboration commune et partagée témoigne de la fonction polyphonique des squiggles , c’est-à-dire de la mise en résonance sinon de la mise en écho des groupes internes du patient et du clinicien.

The addition of metal nanoparticles in the Bi-based superconductors has shown the disorder produced by the cations incorporation in the crystal structure affects the TC (Critical temperature) of the system. the addition of new mixture of (Cr2O3: SnO)x on high temperature superconductors HTS Bi1.6Pb0.4 Sr2Ca2Cu3O10+δ (Bi-2223) with ratio 1:1 where x = 0.0, 0.05, 0.10, 0.15 and 0.20 was investigated by solid-state reaction technique was used to prepare superconductor samples. Samples were characterized by X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FS-EM), Energy Dispersive X-ray (EDX), and electrical resistivity. the results of XRD proved that the structure of 2223 remains the same even with the addition of (Cr2O3: SnO)x nanoparticles. The phase 2223 has the majority even phase Bi-2212 and phase Ca2PbO4 showed a contribution inside structure. As a result of the change physico-chemical properties resistivity of the doped optimized sample x = 0.10 was increasing 2.2 K approximately rather than the undoped one then decreased gradually up to x = 0.20. From resistivity measurement, the TC of 2223 doped with (Cr2O3: SnO)x at x = 0.10 was 113.2 K approximately. The addition of metal oxides in superconductor materials has been considered to be one of the most promising materials for large scale applications in superconducting industry.

Published: August 2020

Duckweed (Lemna Gibba) was successfully used for phytoremediation of wastewater containing 1,4-dioxane, which could also result in biomass with high protein and carbon content. 1,4-dioxane is not easily removed or separated from wastewater by traditional physicochemical processes such as coagulation and activated carbon adsorption because of its high solubility [1]. Three duckweed-pond continual streams (DWs) lab-scale reactors, i.e., one pond (DW1), two ponds (DW2), and three ponds (DW3), were operated at variable hydraulic retention times (HRTs) of 2, 4, and 6 days respectively that are designed to treat wastewater containing 1,4dioxane. The results showed that the removal efficiency of 1,4 dioxane, COD, TOC, and ammonia were quite high in the DW3 which had the highest removal efficiency in 1,4-dioxane and NH4-N. 1,4-Dioxane and NH4-N removal efficiencies using DW3 (i.e., 56.9 ± 25% and 87.2 ± 7.1%, respectively) were slightly higher than that obtained using DW2 (i.e., 44.8 ± 19.6% and 81.9 ± 8.6%, respectively). Further, it was noted that, at DW3, the average effluent pH decreased that range from (8.80) to (7.45, c (TDS) decreased that range from( 921.5 ± 120.6) to (837.6 ± 83.6) mg/L, and Dissolved Oxygen (DO) increased that range from (3.5 ± 1.9) to (7.5 ± 3) mg/L. Eventually, DW removed 1,4dioxane effectively from wastewater, representing an effective, low operation, eco-friendly, and maintenance costs technology.

Authors: Ibrahim Alaa A. , Fath Hassan E.S. , Ibrahim Mona G.
Published: August 2020

Falling film on horizontal tube evaporators, of both Mechanical Vapor Compression (MVC) and the Multi-Effect Distillation (MED) desalination systems, plays an important role in the heat and mass transfer (evaporation) and accordingly the systems productivity. Falling film thickness is mainly influenced by the intertube space, circumferential angle and the film’s Reynolds number. This paper presents two-dimensional numerical study of falling film thickness around horizontal tube in MVC and MED evaporators. The study is based on computational fluid dynamics (CFD) using volume of fraction (VOF) as a multi-phase technique in ANSYS Fluent. The numerical model is developed in order to study the heat and mass transfer charactristics, the liquid falling film behaviour and thickness distribution around circular horizontal. Four CFD study cases are developed to simulate the falling film behaviour at circumferential angle range from 150 to 1650 with inter-tube spacing of 10 mm, 16 mm, 33 mm and 40 mm and for constant value of flow rate and at the same surrounding conditions. Simulations are conducted using a domain of only two tubes with 20 mm outer diameter.The results from the numerical models are compared with the published experimental correlations, showing a comparatively reasonable agreement. In addition, a parametric study is carried out to illustrate the effect of flow Reyonlds number (Re) and intertube space on the average circumferential film thickness and heat transfer rates.

Published: August 2020

Polypyrrole nanoparticles prepared in the presence and absence of polyvinylpyrrolidone (PPy/PVP) fine black powders have been synthesized as adsorbents for the removal of copper Cu (Ⅱ) and iron Fe (Ⅲ) ions from aqueous solution. PPy and PPy/PVP were chemically prepared by using ferric chloride as an oxidant, and distillate water as a solvent with and without polyvinylpyrrolidone as a surfactant. The prepared PPy and PPy/PVP adsorbents were characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Brunauer–Emmett–Teller (BET) surface area, and Fourier Transform Infrared spectroscopy (FTIR). The results display BET surface area equals 7.88 and 21.93 for PPy and PPy/PVP, respectively. The data also shows that PPy/PVP acts as flawless adsorbent for the removal of copper and iron ions from aqueous solution with sequestration percentage of 90% and 83% in 2 hours respectively.

Published: August 2020

Microreactor technology has drawn attention in many industrial applications, especially those that requires the use of low flow rates whereas the flow is considered to be stratified. At such low flow rates, the reactor performance is usually down especially if mass transfer occurs mainly by diffusion. In the present work, the mixing performance of a novel hepatic sinusoids-based microreactor has been investigated using Villermaux–Dushman protocol. The protocol is an iodide/iodate chemical test reaction that relies on testing the absorbance of the product at 352 nm as an indication of the formation of triiodide. The investigation is carried out at low flow rates ranges from 0.5 to 3 ml/min. The novel microreactor has proven to give satisfactory performance and is easy to be fabricated as it consists of a single layer. The absorbance of light ranges between 0.29 to 0.48 resulting on the creation of limited amount of triiodide ions. It is also noticed that the mixing performance of the reactor is nearly the same over the whole studied range of flow rate. The mixing quality is also determined using another system containing 200 ppm congo red aqueous solution and pure distilled water. About 94% to 96% mixing quality is achieved.

Authors: Bakkar Ashraf
Published: August 2020

This paper presents, firstly, an overview of results arisen worldwide on semiconductive thin films used in photovoltaic (PV) cells as a function of time and efficiency. Secondly, the paper demonstrates the electrodeposition of silicon and gallium arsenide films suggested for PV cells, with a focus on electrodeposition from ionic liquids. Ionic liquids, due to their wide electrochemical window, are used for the electrodeposition of elements and compounds impossible to be electrodeposited from aqueous solutions. Finally, a new approach, referred to a recent patent by the author, is illustrated to facilitate the practical electrodeposition of semiconductors from ionic liquids that can be suggested for industrial applications.

Published: August 2020

The innate immune system is the first line of defense against bacterial and viral infections. The recognition of pathogen-associated molecular patterns by the RIG-I–like receptors, TLRs, and cGAS leads to the induction of IFN-I by activating the transcription factor IRF-3. Although the mechanism of IRF-3 activation has been extensively studied, the structural basis of IRF-3 activation upon phosphorylation is not fully understood. In this study, we determined the crystal structures of phosphorylated human and mouse IRF-3 bound to CREB-binding protein (CBP), which reveal that phosphorylated IRF-3 forms a dimer via pSer386 (pSer379 in mouse IRF-3) and a downstream pLxIS motif. Size-exclusion chromatography and cell-based studies show that mutations of key residues interacting with pSer386 severely impair IRF-3 activation and IFN-β induction. By contrast, phosphorylation of Ser396 within the pLxIS motif of human IRF-3 only plays a moderate role in IRF-3 activation. The mouse IRF-3/CBP complex structure reveals that the mechanism of mouse IRF-3 activation is similar but distinct from human IRF-3. These structural and functional studies reveal the detailed mechanism of IRF-3 activation upon phosphorylation.

Published: August 2020

Abstract

Arnold-Chiari malformation (ACM) is one of the factors that cause death in newborns and infants. Ultrasound (US) is the preferred imaging method for pregnant patients. For the diagnosis of ACM II in the developing fetus, direct and indirect sonographic findings must be fully known. However, Magnetic Resonance Imaging (MRI) is increasingly used in patients whose sonographic diagnosis is uncertain. Fetal MRI is performed for patients such as central nervous system (CNS) abnormalities, neural tube defects, congenital diaphragmatic hernia and masses obstructing the airway that are considered fetal surgery. In this case report, ACM-II detected at 23 weeks 4 days of gestation was presented. The role of prenatal MRI in the recognition of these features, malformation and prognostic value was discussed.
RECONCEPTUALIZING SOCIAL SCIENCES
Authors: Ahmar Dr. Moonis
Published: August 2020

Transformation in the discipline of Social Sciences is a global phenomenon but in the post-colonial societies it means two things. First, far reaching societal changes resulting into the emergence of new fields in Social Sciences fulfilling new conditions and requirements of society. Second, the growing need and relevance of Social Sciences research so as to address issues which cause serious societal changes. Marginalization of Social Sciences and social scientists in case of Pakistan is not a new phenomenon. There cannot be any time line which can be given for modernizing Social Sciences in Pakistan which can meet the criteria and standards of 21st century. Yet, those who teach and do research in different subjects of Social Sciences must come forward and play a leadership role in this regard. This would require a paradigm shift in the arena of admitting students and appointing faculty so that the best stuff both at the student and faculty level is motivated to join the subjects of Social Sciences in order to ensure quality control and standard which seem to have deteriorated in the last four decades is restored. By attracting the best talent in the subjects of Social Sciences one can expect positive transformation in the state and societal patterns of Pakistan.
