Published: December 2020

Beton tanpa pasir merupakan beton ringan yang digunakan dengan mengedepankan faktor akuistik. Susunannya tanpa agregat halus sehingga memiliki rongga yang besar dan kuat tekan yang dihasilkan jauh lebih rendah dibandingkan beton norma akibat rongganya yang besar. Untuk memperbaiki kualitas ataupun meningkatkannya perlu pemilihan material. Salah satu material yang diketahui mampu meningkatkan sifat tersebut adalah fly ash. Penggunaan fly ash sebagai bahan pembuat beton sudah banyak dilakukan, akan tetapi pemanfaatannya sebagai bahan pembuat beton non pasir belum banyak dilakukan. Tujuan dari penelitian ini yaitu untuk mengetahui pengaruh penambahan limbah fly ash batubara terhadap kuat tekan beton non-pasir. Metode penelitian yang digunakan dalam pembuatan beton non-pasir ini yaitu trial and error method of mix design. Perlakuan yang diberikan berupa dua faktor yaitu variasi fly ash dan umur beton. Fly ash yang diberikan terdiri dari 5 (lima) taraf yaitu subtitusi 0 %,10%, 20 %, 30 %, dan penambahan 10 % dari jumlah semen yang digunakan. Faktor yang kedua berupa umur beton yang terdiri dari 3 (tiga) taraf yaitu umur beton 7, 14, dan 28 hari. Hasil penelitian menunjukkan penggunaan fly ash mampu meningkatkan kuat tekan beton non-pasir. Kuat tekan tertinggi diperoleh pada perlakuan penambahan fly ash sebanyak 10 % yaitu sebesar 6,443 N/mm². Komposisi optimum diperoleh pada perlakuan subtitusi fly ash sebanyak 20 %, dengan peningkatan kuat tekan beton non-pasir sebesar 46,64 % dari beton non-pasir normal. Penambahan Fly Ash 10 % mencapai selisih kuat tekan yang tidak begitu signifikan dari kuat tekan beton non-pasir subtitusi Fly Ash 20 % yaitu sebesar 4,55 % dengan demikian subtitusi Fly Ash 20 % lebih efisien.

El presente trabajo tiene como objetivo analizar algunas de las experiencias de representación Drag queen en el reality show Rupaul’s Drag Race que en su dimensión productiva, exponen una base identitaria distinta a la de otros espacios del colectivo LGBT+, así como un locus de enunciación centrado en “prácticas subversivas” que desbordan algunos de los referentes heteronormativos dominantes en la televisión y crean un espacio alternativo en la televisión.
La aproximación se realizará a partir del concepto de performatividad de género desarrollado por Judith Butler a principios de la década de los noventa y que en términos generales refiere a la repetición ritualizada de comportamientos y conductas que logra su efecto por medio de su naturalización del género en el contexto del cuerpo rechazando la idea de que exista una esencia natural y anterior al sujeto, siendo un ejemplo de ello, la subjetividad Drag.
Cayendo Como Moscas: Representaciones Mediáticas y Sociodigitales de la Responsabilidad Social Universitaria en Tiempos de Covid-19
Authors: Méndez Fierros Hugo 
Published: December 2020

Se interpretan las representaciones mediáticas y sociodigitales de las acciones de Responsabilidad social universitaria (RSU) de una institución de educación pública mexicana frente a la covid-19. Se analizaron 128 productos periodísticos, 68 publicaciones en la página de Facebook institucional y 13,755 comentarios de la comunidad virtual, en el periodo del 11 de marzo al 11 de mayo del 2020. Los recursos teóricos de las Representaciones sociales, de la Producción social de la comunicación y Agenda setting, empleando como método el análisis de contenido, permitieron confirmar la centralidad de la comunicación en la gestión de un problema mundial en la escala regional. Asimismo, se concluye que durante un momento de crisis, la RSU es una fuente de acciones con impactos sociales positivos que retroalimentan recursivamente los vínculos entre identidad regional e identidad universitaria, a través de producciones simbólicas. De las representaciones de la RSU en medio de la pandemia, emergió una categoría analítica denominada Orgullo Universitario, emana como una emoción colectiva enlazada al sentido de pertenencia y a la identidad universitaria. La investigación sobre comunicación y emociones en los entornos mediático-digitales se abre como una veta, si no nueva, que exige ampliar su estudio desde perspectivas interdisciplinarias.Re
Lecture littéraire et « enroulement spiralaire » : le défi de la bifurcation
Authors: Rouvière Nicolas 
Published: December 2020

L’article interroge la conception de la lecture littéraire comme « enroulement spiralaire » (Shawky-Milcent, 2014), au regard d’un dispositif à priori éloigné de l’approche du sujet lecteur, en raison de son objet et du guidage qu’il implique. Il s’agit de susciter une relecture de la nouvelle de Maupassant (1885) « La Parure » en classe de quatrième, au regard d’un intertexte juridique. Après avoir posé le cadre théorique de deux composantes de la lecture axiologique, l’article présente le dispositif et analyse les moments de classe concernés, du point de vue des gestes de lecture et des gestes professionnels. Il discute ensuite la prise en compte d’un tel dispositif au titre de l’enroulement spiralaire, afin de questionner en retour la didactique du sujet lecteur sur les savoirs contextuels, la démarche d’enseignement et le guidage.The article questions the conception of literary reading as a “spiral coil” (Shawky-Milcent, 2014), in relation with a device that is a priori far removed from the approach of the reading subject, because of its object and the guidance it implies. In the Year 9/8th grade, the aim, the aim is to encourage a re-reading of Maupassant's short story “La Parure”, with regard to a legal intertext. After establishing the theoretical framework of two components of axiological reading, the article presents the device and analyses the class moments concerned, from the point of view of reading and professional gestures. Then, it discusses the consideration of such a device under spiral winding, in order to question in return the didactics of the reader subject on contextual knowledge, the teaching approach and guidance.
« Ça a bien marché ! » : de la créativité lectorale à la créativité didactique et pédagogique dans la conduite d’une lecture analytique en classe.
Authors: Shawky-Milcent Bénédicte 
Published: December 2020

On observe, au collège comme au lycée, des propositions de démarches créatives pour précéder, accompagner et prolonger la lecture analytique d’un texte, encourageant une réception sensible et sensorielle du texte, la mobilisation d’autres formes artistiques, des actualisations variées. Dans cet article nous formons l’hypothèse que la créativité déployée dans ces dispositifs puise dans la créativité lectorale singulière des enseignants ou des enseignants chercheurs qui les conçoivent. Dans un premier temps on interrogera la notion de créativité dans la perspective retenue, puis on confrontera cette hypothèse aux résultats obtenus lors d’une enquête menée auprès de 40 enseignants du secondaire portant sur les liens entre lecture privée et pratique professionnelle.In middle and high school, there are proposals for creative approaches to precede, accompany and lengthen the analytical reading of a text, encouraging a sensitive and sensory reception of the passage, the mobilization of other artistic forms, and a variety of updates. In this article we postulate that the creativity deployed in these methods relies on the singular readership creativity of the teachers or teacher-researchers who design them.First, the notion of creativity will be questioned from the chosen perspective, then this hypothesis will be compared with the results of a survey conducted among forty secondary school teachers on the links between private reading and professional practice.

Published: December 2020

Background Organs transplantation is the only treatment for end-stage organ failure. However, the disparity between organs availability and the number of patients in the waiting lists is widening globally, especially in Iraq for many reasons. This study aims to assess the level of attitudes and perceptions among Iraqi young adults towards organs donation and transplantation as the first study to be conducted in Iraq for such purpose. Methods: This observational study was conducted among 912 Iraqi young adults through a structured questionnaire which was disseminated among social media platforms. Participants consented before filling the questionnaire and their responses were analyzed to test the hypothesis of the study. Results Most of the participants were females, Muslims and in their undergraduate level. Overall, 84.2% of the participants were willing to donate their organs after death and (97.9%) of them actually agreed to sign for organs donation. Most of those who were not willing to donate have no idea whether their religion approves it or not. There was no statistically significant difference in willingness to donate between different socioeconomic classes or residency areas. Conclusions Most of the participants are convinced with donating their organs after death and are willing to sign for organ donation programs, advocating for initiating an official governmental transplant agency with multiple local committees distributed among health directorates all over the country managing it. The hesitancy to donate organs was attributed mostly to religious and associated with lack of knowledge issues, thus education might be the key to positive attitudes.
Effect of Covid-19 Pandemic on Academic Accreditation
Authors: Abdelhadi Abdelhakim 
Published: December 2020

Background Higher education quality is an essential measurement for any country's development, since education is a significant source of new sciences and its applications. This importance works as one of the cornerstones toward public health. The sudden change from traditional classroom teaching and learning to online education and learning process did not give educators the time to adjust the teaching material or, for that matter, did not give the program administrators the time to prepare for the needed documents toward the accreditation. This situation creates a dilemma for all members involved in certification. This research is addressing this issue from the accreditation point of view. Design Brainstorming methodology is used to study the effect of COVID-19 pandemic on the academic/health accreditation. Methods Cause and effect diagram (Fishbone diagram) is used to present the ideas presented by institutional participants related to the effect of COVID-19 on the accreditations processes. Conclusions The study shows that COVID-19 pandemics have dramatic influence on accreditation processes, which may lead to change and/or adjust the rules and the requirements of the educational institutions due to changes in the fulfillment of the accreditation by the institutions during this period.

ABSTRACT

Introduction
Early childhood caries (ECC) has an impact on deciduous teeth of infants and children. Pediatricians and family physicians are often in a better position to evaluate children at an early age and are capable of assessing the oral health of children during regular visits. The purpose of this study was to assess the knowledge, attitude, and practice of ECC among pediatricians and family physicians in Riyadh region.

Materials and methods
A close-ended self-administered questionnaire was hand-circulated and mailed to pediatricians and family physicians in 5 tertiary hospitals in Riyadh (King Khalid University Hospital, King Saud Medical City, King Fahad Medical City, Prince Sultan Medical Military City, Security Forces Hospital) to assess the knowledge, attitude, and practice (KAP) about ECC.

Results
A total of 207 medical practitioners participated in the study. The mean KAP scores were compared across different categories by applying Kruskal Wallis tests. Pediatricians showed higher knowledge [5.05 vs 4.28, p = 0.000], attitude [2.38 vs 2.30, p = 0.565], and practice [4.0 vs 3.58, p = 0.003] scores toward early childhood caries compared to the family physicians. The mean knowledge and practice scores were significantly higher among pediatricians compared to the family physicians. However, no significant difference was observed in attitude scores.

Conclusion
Most of the physicians have knowledge regarding some aspects of early childhood caries but not the identification of early childhood caries. It is the need of the hour to formulate oral health information programs catering to both pediatricians and family physicians.

Abstract2D heterostructures have garnered significant interest in the scientific community owing to their exceptional carrier transport properties and tunable band alignment. The fabrication of these heterostructures on a wafer scale is crucial for advancing industrial applications but remains particularly challenging for metals with low sulfidation activity, such as Hf. Herein, the one‐pot method is developed for fabricating wafer‐scale HfSe2/WSe2 interlayer heterostructures with vertically aligned van der Waals layers via interface‐enhanced selenization and self‐guided growth. By depositing a W layer (high sulfidation activity) over a Hf layer, followed by a one‐pot selenization process, the chemical combination between Hf and Se atoms is enhanced through interfacial Se diffusion and confined lattice reaction. Moreover, the WSe2 layers grow perpendicular to the substrate and further guide the crystallization of the bottom HfSe2 layers. The resulting heterostructures, characterized by covalent bonds, demonstrate significant charge transfer, enhanced piezoelectricity, notable rectification effects, and Si‐compatible transistor integration. This interface‐enhanced selenization and self‐guided growth pathway may provide valuable insights into the fabrication of covalently connected interlayer heterostructures involving metals with low sulfidation activity, as well as the development of high‐density integrated circuits.

Published: February 2025

AbstractPhototherapy based on micro light‐emitting diodes (µLEDs) has gained enormous attention in the medical field as a patient‐friendly therapeutic method due to its advantages of minimal invasiveness, fewer side effects, and versatile device form factors with high stability in biological environment. Effective cosmetic and medical phototherapy depends on deep light penetration, precise irradiation, and simultaneous multi‐site stimulation, facilitated by three‐dimensional (3D) optoelectronics specifically designed for complex human matters, defined here as 3D µLEDs. This perspective article aims to present the functionalities and strategies of 3D µLEDs for human‐centric phototherapy. This study investigates the effectiveness of phototherapy enabled by three key functionalities such as shape morphing, self‐adaptation, and multilayered spatiotemporal mapping of 3D µLEDs. Finally, this article provides future insights of 3D µLEDs for human‐centric phototherapy applications.

ABSTRACTPatient registries play a crucial role in advancing our understanding of rare diseases, enabling the collection of comprehensive clinical and molecular data that inform diagnosis, treatment, and management strategies and advance our understanding of rare diseases. We showcase the first Swiss registry of 796 patients with suspected or confirmed connective tissue disorders (CTD) who were referred to our center over a period of 26 years between 1995 and 2022. The registry contains information on the natural history, anthropometrics, biochemical, histological, and genetic analyses. 61.3% of patients were referred by other hospitals or genetic specialists, with the primary reasons for referral being suspicion of Ehlers–Danlos syndrome (EDS) (53.6%) and osteogenesis imperfecta (OI) (28.1%). Molecular confirmation of these diagnoses was obtained in 60 cases of EDS and 98 cases of OI through genetic testing. In‐depth analyses of 173 OI patients revealed that the majority of OI cases were caused by mutations in COL1A1 or COL1A2. Rarer variants were identified in genes involved in collagen synthesis and bone regulation. Genotype–phenotype correlations were observed in a small subset of patients, with a high prevalence of glycine substitutions in COL1A1 and COL1A2 variants associated with severe phenotypes. This registry offers insights into the molecular underpinnings of EDS and OI and underscores the importance of genetic testing for accurate diagnosis and management.
Rhodium‐Catalyzed Asymmetric Reductive Cyclization of Cyclohexadienone‐Tethered (Z)‐α,β‐Unsaturated Compounds

Published: February 2025

The hydrobenzofuranone framework is a core structural motif found in natural products. Herein, we report an efficient rhodium‐catalyzed asymmetric reductive cyclization of cyclohexadienone‐tethered (Z)‐α,β‐unsaturated amides and esters, providing hydrobenzofuranones bearing three consecutive stereogenic centers in cis‐cis‐form with good yields, moderate diastereoselectivity, and excellent enantioselectivity. The subgram‐scale experiment and downstream transformations underscore the utility of this protocol. Furthermore, DFT calculations show that the enantioselectivity and diastereoselectivity are determined by the cyclization step.
