Published: June 2021

On remarque souvent dans les écrits dans le domaine de l’éducation une invitation à « varier son enseignement ». Si cette expression semble claire à première vue, elle devient vite ambigüe à la suite d’un examen un peu plus approfondi car les critères sur lesquels se base cette variation ne sont pas explicités. Tout se passe comme si varier les activités d’apprentissage est vu comme un principe qui a une valeur en soi, mais il ne constitue pas un principe d’action pertinent car il risque en effet de créer de la confusion en mettant sur le même pied des activités qui peuvent avoir des effets positifs ou négatifs selon les contextes d’enseignement. L’objectif de cet article est de formuler des critères de choix d’activités à la lumière des travaux sur l’enseignement explicite, notamment en ce qui concerne la gestion des apprentissages et la gestion de la classe. Le niveau de compétence des lèves, la complexité de la tâche à accomplir, le temps disponible et l’importance du contenu sont les critères retenus en ce qui concerne la gestion des apprentissages. Le maintien du vecteur d’action renvoie au critère lié à la gestion de la classe.

Influence of Waste Tire Rubber Particles Size on the Microstructural, Mechanical, and Acoustic Insulation Properties of 3D-Printable Cement Mortars
Authors: Sambucci Matteo , Valente Marco 
Published: June 2021

3D printing technologies of construction materials are gaining ground in the building industry. As well documented in the literature, these advanced manufacturing methodologies aim to reduce work-related injuries and materials waste, enhancing architectural flexibility which would enable more sophisticated designs for engineering and aesthetic purposes. In this framework, the development of functional and eco-sustainable printable materials represents an extremely attractive challenge for research, promoting digital fabrication to reach its maximum cost-effective and technological potentials. The use of recycled tire rubber particles in 3D printable Portland-based compounds is an exclusive contribution in this field. This line of research aims to integrate the well-known engineering performances of rubber-cement materials with the advanced peculiarities of additive manufacturing methodologies. As an innovative contribution, the authors propose here a detailed study on the possible relationship between rubber particle size and technological properties of the 3D printable mix. Specifically, two groups of continuous size grading polymer aggregates (0-1 mm rubber powder and 1-3 mm rubber granules as fine and coarse fractions, respectively) were analyzed in terms of impact on rheology, print quality, microstructure, mechanical properties, and acoustic insulation performance. Concerning the print quality, rubber aggregates altered the fluidity of the fresh mix, improving the adhesion between the printed layers and therefore enhancing the mechanical isotropy in the post-hardening sample. A remarkable influence of the rubber gradation on the compounds’ behaviour was found in hardened properties. By comparing the rubberized compounds, the fine polymer fraction shows greater interfacial cohesion with the cement paste. However, more significant mechanical strength loss was found due to a greater reduction in density and increased porosity degree. On the other hand, mortars doped with larger rubber particles tend to have a higher unit weight, finest pore distribution, minor mechanical strength drop, and higher ductility but worse interface binding with the matrix. Regarding the acoustic insulation properties, a proper balance between rubber powder and granules in the mixes allows to obtain comparable/superior performance compared to plain mortar but the effect of the aggregate size is strongly dependent on the sound frequency range investigated. Future findings revolve around applicability studies of these formulations in civil and architectural fields, benefiting from the design flexibility of 3D printing.

Authors: Dacuan Cecielle N. , Abellana Virgilio Y. , Canseco Hana Astrid R. 
Published: June 2021

Concrete provides a high degree of protection against corrosion of embedded steel reinforcement. Owing to the harsh environmental conditions and the presence of aggressive elements from the marine environment, deteriorating corrosion affects the durability of reinforced concrete structures. This study evaluated the effectiveness of bamboo leaf ash BLASH as a supplementary cementing material or admixture with Portland cement to improve the durability of reinforced concrete structures. Specimens of 0, 10, 15, and 20% BLASH mixtures were prepared using 16, 20, and 25 mm steel reinforcements. A total of 100 cylindrical specimens were cast and used in this study. The specimens were accelerated by corrosion using impressed current techniques and a galvanostatic method in a simulated environment. The results show that specimens with a BLASH content of 10% exhibited superior performance and exhibited longer corrosion initiation and propagation times. It has a higher resistance to acid penetration and lower corrosion rates. The crack parameters of the specimen with BLASH admixtures, such as the crack width and crack frequency, were negligible. The use of BLASH as an admixture strengthens its durability and improves its residual strength and serviceability. Doi: 10.28991/cej-2021-03091707 Full Text: PDF

Published: June 2021

Tulisan ini dilatarbelakangi oleh adanya perubahan dan perkembangan garap musikal dari Sekar Macapat Kinanthi menjadi beberapa bentuk gendhing, baik gendhing vokal maupun bentuk gendhing gamelan. Penulis menggunakan istilah perubahan dan perkembangan garap karena pada kenyataannya Sekar Macapat Kinanthi tidak hanya dibentuk menjadi gendhing gamelan saja, akan tetapi juga mengalami perkembangan dalam bentuk sajian vokal yang lain, seperti: sajian bawa dan palaran.Melalui analisis perbandingan sèlèh nada pada setiap baris sekar Macapat Kinanthi dengan beberapa bentuk gendhing sasaran, maka penulis mencoba untuk mengkorelasikan kerangka balungan gendhing, lagu vokal gerongan, dan garap rebaban pada bentuk-bentuk gendhing sasaran dengan sèlèh nada dan alur lagu dari jenis Sekar Macapat Kinanthi yang menjadi dasar penciptaannya. Oleh karena itu, pendekatan yang digunakan oleh penulis adalah pendekatan musikologis, dengan mendasarkan pada konsep garap, balungan, bentuk, dan struktur gendhing. Adanya penelitian ini, karena sebuah pemikiran sebagaimana yang dikemukakan oleh R. Ng. Warsapradangga, bahwa adanya suatu gendhing adalah dari sekar.

Published: June 2021

Gending lampah tiga composed by Harjasubrata in the 1950s. At the very beginning of its existence, lampah tiga composition focused and working on vocals, so gending lampah tiga has not been equipped with settled garap instruments. Most pengrawits find it hard to present gending lampah tiga, especially on ricikan gender, this is because the information about genderan lampah tiga is still limited. This article is entitled “Garap Genderan in Gending Lampah Tiga”, the problem described in this article is how to present garap genderan in gending lampah tiga. The method that used to solve the problem in this article is to analyze and transcribe the presentation of gending lampah tiga, then interpreted.The writer hopes to provide an offer about how to interpret genderan in gending lampah tiga and to give a “little” contribution of thoughts for the development of karawitan science.

Investigation of the negative impacts of stress on reproduction has largely centered around the effects of the adrenal steroid hormone, corticosterone (CORT), and its influence on a system of tissues vital for reproduction—the hypothalamus of the brain, the pituitary gland, and the gonads (the HPG axis). Research on the action of CORT on the HPG axis has predominated the stress and reproductive biology literature, potentially overshadowing other influential mediators. To gain a more complete understanding of how elevated CORT affects transcriptomic activity of the HPG axis, we experimentally examined its role in male and female rock doves (Columba livia). We exogenously administrated CORT to mimic circulating levels during the stress response, specifically 30 min of restraint stress, an experimental paradigm known to increase circulating CORT in vertebrates. We examined all changes in transcription within each level of the HPG axis as compared to both restraint-stressed birds and vehicle-injected controls. We also investigated the differential transcriptomic response to CORT and restraint-stress in each sex. We report causal and sex-specific effects of CORT on the HPG transcriptomic stress response. Restraint stress caused 1567 genes to uniquely differentially express while elevated circulating CORT was responsible for the differential expression of 304 genes. Only 108 genes in females and 8 in males differentially expressed in subjects that underwent restraint stress and those who were given exogenous CORT. In response to elevated CORT and restraint-stress, both sexes shared the differential expression of 5 genes, KCNJ5, CISH, PTGER3, CEBPD, and ZBTB16, all located in the pituitary. The known functions of these genes suggest potential influence of elevated CORT on immune function and prolactin synthesis. Gene expression unique to each sex indicated that elevated CORT affected more gene transcription in females than males (78 genes versus 3 genes, respectively). To our knowledge, this is the first study to isolate the role of CORT in HPG genomic transcription during a stress response. We present an extensive and openly accessible view of the role corticosterone in the HPG transcriptomic stress response. Because the HPG system is well conserved across vertebrates, these data have the potential to inspire new therapeutic strategies for reproductive dysregulation in multiple vertebrate systems, including our own.

Published: June 2021

BackgroundHumans are widely exposed to environmental perfluoroalkyl substances (PFAS), which may affect fetal neurodevelopment. Brain-derived neurotrophic factor (BDNF) is an important factor in neurodevelopment, but its role in PFAS-induced neurotoxicity is unclear. We investigated the association between prenatal PFAS exposure and fetal BDNF level in the umbilical cord blood in a large prospective cohort.MethodsA total of 725 pregnant women who participated in the Shanghai Birth Cohort were included. 10 PFAS were measured by high-performance liquid chromatography/tandem mass spectrometry (HPLC/MS-MS) in the plasma samples of early pregnancy. The BDNF level was determined by ELISA. The concentration of total mercury (Hg) in the umbilical cord blood was tested by cold vapor atomic absorption spectrometry (AAS) and included as a main confounder, along with other covariates. Multiple linear regression was used to explore the associations between PFAS concentrations and BDNF level. Quantile-based g-computation was applied to explore the joint and independent effects of PFAS on BDNF level.ResultsThe mean BDNF level in the total population was 10797 (±4713) pg/ml. Male fetuses had a higher level than female fetuses (P&lt;0.001). A significant positive association was observed between PFHxS and BDNF level after adjusting for potential confounders [β=1285 (95% CI: 453, 2118, P=0.003)]. No association was observed between other PFAS congeners and BDNF level. Results of the mixed exposure model showed that the joint effects of PFAS mixture were not associated with BDNF [β=447 (95% CI: -83, 978, P=0.10)], while the positive association with PFHxS exposure remained significant after controlling for other PFAS [β=592 (95% CI: 226, 958, P=0.002)]. The above associations were more prominent in male [β=773 (95% CI: 25, 1520, P= 0.04)] than female fetuses [β=105 (95% CI: -791, 1002, P= 0.82)] for the mixed effects.ConclusionsPrenatal exposure to PFHxS was associated with an increased BDNF level in the umbilical blood, especially in male fetuses.

ObjectiveTo identify the existence of a correlation among the various organs affected, focusing primarily on immuno-dermatological aspects, and to create a risk prediction model of organ-specific complications.Material and MethodsFifty-two patients with stable scleroderma, followed between 2015 and 2019, were investigated through an extensive multidisciplinary evaluation in the last year.ResultsPatients with lung involvement presented a worse degree of skin fibrosis than patients without it (p &lt;0.001). No relationship was observed for the heart, kidney, and esophagus. Patients with pulmonary involvement had a lower pressure of the low esophagus sphincter and a higher Warrick score than patients without it (p &lt;0.05). Age was significantly higher in patients with kidney involvement. Diffuse scleroderma patients had a worse pulmonary impairment than limited scleroderma patients (p &lt;0.05). The manometric “sclerodermic” pattern was observed to be the most frequent (55.6%, p &lt;0.05) in dcSSc patients while the sclerodermic and normal pattern were equally represented (41.2 and 32.4% respectively, p &lt;0.05) in lcSSc patients. When compared to the negative serological groups, anti-Scl-70 positive patients presented a worse lung involvement while anti-centromere patients presented a better lung outcome (p &lt;0.05). PM-Scl 100/75 positive patients presented mostly a pulmonary fibrotic pattern (p &lt;0.05) and, also, heart complications were more likely associated with anti PM-Scl 100/75 positivity (p &lt;0.05). The risk prediction model for organ-specific complications had an accuracy of 84.4% (95%CI 78, 89) in complication-site prediction, AUC of 0.871, 86% of sensitivity, and 83% of specificity, Cohen’s Kappa (k) of 0.68.ConclusionsOut of all the organs studied, the skin is the one that correlates with the lung. Patients with a diffuse form of disease presented more frequently the anti Scl-70 antibody and had a worse lung and esophageal involvement (scleroderma pattern) than the negative group. Conversely, patients with limited disease presented all positive for the anti-centromere antibody with a better lung involvement than the negative group, without any difference among the esophageal manometric pattern. Anti PM-Scl 100/75 antibody patients were associated with pulmonary fibrosis and presented cardiac involvement. The model created has demonstrated excellent values of sensitivity, specificity, and accuracy, but further studies are needed for validation.
Immunothrombosis in Acute Respiratory Dysfunction of COVID-19

Published: June 2021

COVID-19 is an acute, complex disorder that was caused by a new β-coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Based on current reports, it was surprising that the characteristics of many patients with COVID-19, who fulfil the Berlin criteria for acute respiratory distress syndrome (ARDS), are not always like those of patients with typical ARDS and can change over time. While the mechanisms of COVID-19–related respiratory dysfunction in COVID-19 have not yet been fully elucidated, pulmonary microvascular thrombosis is speculated to be involved. Considering that thrombosis is highly related to other inflammatory lung diseases, immunothrombosis, a two-way process that links coagulation and inflammation, seems to be involved in the pathophysiology of COVID-19, including respiratory dysfunction. Thus, the current manuscript will describe the proinflammatory milieu in COVID-19, summarize current evidence of thrombosis in COVID-19, and discuss possible interactions between these two.
