Vitamin K antagonists represented for more than 50 years the only oral anticoagulant treatment option, though encumbered by numerous food and drug interactions, with direct impact on the safety and efficacy of this treatment. The frequent complications of anticoagulant treatment with vitamin K antagonists led to the need for the emergence of new oral anticoagulants (NOAC). The main NOACs used today are dabigatran, rivaroxaban and apixaban. NOAC have a number of advantages over antivitamin K anticoagulants: fewer drug interactions, no food interactions, rapid onset of the anticoagulant action, rapid clearance, no need for INR monitoring. NOAC therapy must be individualized according to patient age, comorbidities and medical history, renal function, concomitant medications. Given that clinical experience with NOAC is still limited in practice, physicians (including family physicians) must monitor these patients and need to pay attention and report any side effects.

The tonsill represents a natural barrier against various infectious pathogens. Around the tonsillar crypts, the tissues produce an area of mechanical defence barrier formed of granulation tissue, neoformation vascularization and leukocytes. In this region a series of complex immunological processes take place, the central role being occupied by immunoglobulin A. Tonsillar outbreak infection is a particular feature of immune response, generating numerous imunopathologic reactions.

Painful hand of aged people is a very common symptom but is often disregarded in comparaison with other clinical signs and symptoms analyzed in these patients. When is reported, are rarely taken into account the multiple pathophysiological and clinical aspects of aging that characterize also the hand. Pain and all these other signs induce unexpected aspects of dysfunctions, from functional impairment to disability. Our aim was to present a review of the most common situations related to painful hand in elderly patients, especially in rheumatological and posttraumatic context. This paper is an update of the most common situations in older patients, that often neglect their distal upper limb in a context of polipathology or in a problematically family and social environment. Also are presented the associated functional consequences and the main therapeutic objectives related to pathophysiological, clinical and functional outcomes.

The authors studied the outcome of a cohort of pediatric acute lymphoblastic leukemia (ALL) patients (33 children and adolescence) diagnosed and treated conforming to modern Chemotherapy Protocols (ALL ICBFM 2002, Interfant 06) in a single Center – Pediatric Clinic, Fundeni Clinical Institute, Bucharest, Romania. They analyzed the factors which determine the prognosis and the outcome of these patients in the course of multi-agent systemic chemotherapy to stand at the base of these Protocols: initial age, initial leukocyte count, blasts immunophenotype, cytogenetic and molecular abnormalities, initial response to cortisone, risk groups, time to obtain the complet remission, etc. Among the factors they discussed, a great value was proven to have the minimal residual disease (MRD) determination in certain check points of Protocols and revaluation of patients risk conforming to MRD values. Using the modern Protocols and continuously watching the evolution on therapy enable the authors to obtain results close to those of European and North American Pediatric Hematology Oncology Centers: OS 90.9% by 40 Mo and EFS 72.7% at the end of the same period of time.
A POTÊNCIA DO DIÁLOGO NA CONSTITUIÇÃO DAS IDENTIDADES E RESISTÊNCIAS
Authors: Costa Andrea , Rios Antonio Marlon
Published: September 2021

O artigo presente sugere reflexão ampla acerca da expressão diálogo de forma a compreender a relação do uso deste termo com a constituição das identidades no contexto da Educação de Jovens e Adultos. Estrutura-se a partir do mergulho teórico dos escritos de Paulo Freire sobre diálogo enquanto direito à palavra e estudos de Bakhtin e Bourdieu que incitam pensar o dialogismo enquanto constituição do ser. Esta análise apresenta-se como relevante diante dos silenciamentos políticos e até mesmo fatais que urgem a construção de uma resistência que se faz e se refaz por meio da linguagem que se opõe à verticalidade monopolizadora do uso da palavra e preconceitos homogeneizadores, invalizadores e excludentes das diversidades das identidades construídas e modificadas ao longo dos tempos.

x
= − 3.391 ± 0.006 and μ

y
= − 0.660 ± 0.004 mas yr−1. The blue straggler stars of King 11 show a centrally concentrated radial distribution. The values of limiting radius, age, and distance are determined as 18.′51, 3.63 ± 0.42 Gyr, and 3.33 ± 0.15 kpc, respectively. The cluster’s apex coordinates (A = 267.°84 ± 1.°01, D = − 27.°48 ± 1.°03) are determined using the apex diagram method and verified using the (μ

) diagram. We also obtained the orbit that the cluster follows in the Galaxy and estimated its tentative birthplace in the disk. The resulting spatial velocity of King 11 is 60.2 ± 2.16 km s−1. A significant oscillation along the Z coordinate up to 0.556 ± 0.022 kpc is determined.
Validation of the PDFI_SS Method for Electric Field Inversions Using a Magnetic Flux Emergence Simulation
Authors: Afanasyev Andrey N. , Kazachenko Maria D. , Fan Yuhong , Fisher George H. , Tremblay Benoit
Published: September 2021

Knowledge of electric fields in the photosphere is required to calculate the electromagnetic energy flux through the photosphere and set up boundary conditions for data-driven magnetohydrodynamic (MHD) simulations of solar eruptions. Recently, the PDFI_SS method for inversions of electric fields from a sequence of vector magnetograms and Doppler velocity measurements was improved to incorporate spherical geometry and a staggered-grid description of variables. The method was previously validated using synthetic data from anelastic MHD (ANMHD) simulations. In this paper, we further validate the PDFI_SS method, using approximately 1 hr long MHD simulation data of magnetic flux emergence from the upper convection zone into the solar atmosphere. We reconstruct photospheric electric fields and calculate the Poynting flux, and we compare those to the actual values from the simulations. We find that the accuracy of the PDFI_SS reconstruction is quite good during the emergence phase of the simulated ephemeral active region evolution and decreases during the shearing phase. Analyzing our results, we conclude that the more complex nature of the evolution (compared to the previously studied ANMHD case) that includes the shearing evolution phase is responsible for the obtained accuracy decrease.

Published: September 2021

In this study, we investigate an extreme ultraviolet (EUV) wave event on 2010 February 11, which occurred as a limb event from the Earth viewpoint and a disk event from the Solar Terrestrial Relations Observatory-Behind viewpoint. We use the data obtained by the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory in various EUV channels. The EUV wave event was launched by a partial prominence eruption. Compared with some EUV wave events in previous works, this EUV wave event contains a faster wave with a speed of ∼445 ± 6 km s−1, which we call a coronal Moreton wave, and a slower wave with a speed of ∼298 ± 5 km s−1, which we call the Extreme Ultraviolet Imaging Telescope (EIT) wave. The coronal Moreton wave is identified as a fast-mode wave and the EIT wave is identified as an apparent propagation due to successive field-line stretching. We also observe a stationary front associated with the fast-mode EUV wave. This stationary front is explained as mode conversion from the coronal Moreton wave to a slow-mode wave near a streamer.
Bayesian Nonparametric Inference of the Neutron Star Equation of State via a Neural Network
Authors: Han Ming-Zhe , Jiang Jin-Liang , Tang Shao-Peng , Fan Yi-Zhong
Published: September 2021

We develop a new nonparametric method to reconstruct the equation of state (EoS) of a neutron star with multimessenger data. As a universal function approximator, the feed-forward neural network (FFNN) with one hidden layer and a sigmoidal activation function can approximately fit any continuous function. Thus, we are able to implement the nonparametric FFNN representation of the EoSs. This new representation is validated by its capability of fitting the theoretical EoSs and recovering the injected parameters. Then, we adopt this nonparametric method to analyze the real data, including the mass–tidal deformability measurement from the binary neutron star merger gravitational-wave event GW170817 and mass–radius measurement of PSR J0030+0451 by NICER. We take the publicly available samples to construct the likelihood and use the nested sampling to obtain the posteriors of the parameters of the FFNN according to the Bayesian theorem, which in turn can be translated to the posteriors of the EoS parameters. Combining all of these data for a canonical 1.4 M

The Bluest Changing-Look QSO SDSS J224113-012108
Authors: Zhang XueGuang
Published: September 2021

In this manuscript, we report a new changing-look QSO (CLQSO) SDSS J2241 at z = 0.059. Based on the multi-epoch Sloan Digital Sky Survey spectra from 2011 to 2017, the flux ratio of broad Hα to broad Hβ has changed from 7 in 2011 to 2.7 in 2017, leading SDSS J2241 with a spectral index α

λ
∼ −5.21 ± 0.02 (λ < 4000) in 2017 to be, so far, the bluest CLQSO. Based on the SDSS spectrum in 2011, the host galaxy contribution with a stellar velocity dispersion of ∼86 km s−1 can be well determined, leading to the M–sigma relation expected central black hole (BH) mass of ∼3 × 106
M
⊙. However, based on properties of the broad Hα emission, the virial BH mass is ∼108
M
⊙, about two magnitudes larger than the mass found through the M–sigma relation. The different BH masses found using different methods indicate that SDSS J2241 is one unique CLQSO. The long-term photometric light curve shows interesting variability that is not expected assuming the Damped Random Walk process commonly applied to active galactic nuclei but probably connected to a central tidal disruption event. Furthermore, based on continuum emission properties in 2017 with no dust obscuration, the moving dust clouds scenario alone cannot be preferred to explain the CLQSO SDSS J2241, because the expected intrinsic reddening-corrected continuum emission was unreasonably higher than the unobscured continuum emission in 2017.
The Evolutionary Effects of the Radius and Moment of Inertia of Rapidly Rotating Neutron Stars
Authors: Lan Lin , Gao He , Ai Shunke , Li Shao-Ze
Published: September 2021

A newly born millisecond magnetar is thought to be the central engine of some gamma-ray bursts (GRBs), especially those that present long-lasting X-ray plateau emissions. By solving the field equations, we find that when the rotational speed of the magnetar is approaching the breakup limit, its radius R and moment of inertia I undergo an obvious evolution as the magnetar spins down. Meanwhile, the values of R and I sensitively depend on the adoption of a neutron star (NS) equation of state (EoS) and the NS baryonic mass. With different EoSs and baryonic mass considered, the magnetic dipole radiation luminosity (L
dip) could be variant within one to two orders of magnitude. We thus suggest that when using the X-ray plateau data of GRBs to diagnose the properties of the nascent NSs, EoS and NS mass information should be invoked as simultaneously constrained parameters. On the other hand, due to the evolution of R and I, the temporal behavior of L
dip becomes more complicated. For instance, if the spin-down process is dominated by gravitational wave emission due to the NS asymmetry caused by magnetic field distortion (

ϵ
∝

p

), the segment L
dip ∝ t
0 could be followed by L
dip ∝ t
−γ
with γ larger than 3. This case could naturally interpret the so-called internal X-ray plateau feature shown in some GRB afterglows, which means the sharp decay following the plateau unnecessarily corresponds to the collapse of the NS. This may explain why some internal X-ray plateaus are followed by late-time central engine activity, manifested through flares and second shallow plateaus.

The distribution of hot interstellar medium in early-type galaxies (ETGs) bears the imprint of the various astrophysical processes it underwent during its evolution. The X-ray observations of these galaxies have identified various structural features related to active galactic nucleus (AGN) and stellar feedback and environmental effects such as merging and sloshing. In our XMM-Newton Galaxy Atlas (NGA) project, we analyze archival observations of 38 ETGs, utilizing the high sensitivity and large field of view of XMM-Newton to construct spatially resolved 2D spectral maps of the hot gas halos. To illustrate our NGA data products in conjunction with the Chandra Galaxy Atlas, we describe two distinct galaxies, NGC 4636 and NGC 1550, in detail. We discuss their evolutionary history with a particular focus on the asymmetric distribution of metal-enriched, low-entropy gas caused by sloshing and AGN-driven uplift. We will release the NGA data products to a dedicated website, from where users can download them to perform further analyses.
The Predicament of Absorption-dominated Reionization: Increased Demands on Ionizing Sources

Published: September 2021

The reionization epoch concludes when ionizing photons reach every corner of the universe. Reionization has generally been assumed to be limited primarily by the rate at which galaxies produce ionizing photons, but the recent measurement of a surprisingly short ionizing photon mean free path of

proper Mpc at z = 6 by Becker et al. suggests that absorption by residual neutral hydrogen in the otherwise ionized intergalactic medium may play a much larger role than previously expected. Here we show that consistency between this short mean free path and the coeval dark pixel fraction in the Lyα forest requires a cumulative output of

This represents a dramatic increase in the ionizing photon budget over previous estimates, greatly exacerbating the tension with measurements of the ionizing output from galaxies at later times. Translating this constraint into the instantaneous ionizing production from galaxies in our model, we find

at z ∼ 6. Even with optimistic assumptions about the ionizing production efficiency of early stellar populations, and assuming the galaxy luminosity function extends to extremely faint sources (M
UV ≤ − 11), complete reionization requires the escape fraction of ionizing photons to exceed 20% across the galaxy population. This is far larger than observed in any galaxy population at lower redshifts, requiring rapid evolution in galaxy properties after the first billion years of cosmic time. This tension cannot be completely relieved within existing observational constraints on the hydrogen neutral fraction and mean free path.
Relationships between Cyberspace Operations and Information Operations
Authors: Haig Zsolt
Published: September 2021

Today thanks to the wireless networking technologies and social networks, the inter-pretation of cyberspace has expanded. According to the three-layered structure of cyberspace, not only logical effects can be induced in this domain, e.g. by malwares, but physical and cognitive effects also appear in the physical and cyber-persona lay-ers, e.g. electronic jamming the wireless communications of network or influencing and manipulating users. This approach provides an opportunity to interpret cyberspace operations in a more complex way and to apply integrated technical and cognitive information capabilities that exploit each others effects. Accordingly, this study pre-sents an expanded interpretation of cyberspace, a novel and complex approach to cyberspace operations, as well as the information capabilities that can be used in these operations.
ELViS is in the Building: The European Loans and Visits System and first experiences with Transnational and Virtual Access
Authors: Islam Sharif , Hardy Helen , Wilson Scott
Published: September 2021

The European Loans and Visits System (ELViS), a DiSSCo e-service in development, will be a one-stop shop for global scientific users to access the Natural Science Collections in Europe. This talk provides a summary of important milestones: the release of version 1.0 of ELViS (released on March 18, 2021) and an analysis of the feedback received from the access providers and scientific users (over 500 submissions were received). ELViS 1.0 was used to facilitate the 3rd Transnational Access (to fund short-term research visits to consortium institutions) and the 2nd Virtual Access call (to fund digitisation-on-demand requests) for SYNTHESYS+ (a European Commission funded project to develop European collections infrastructure). This milestone is the culmination of activities in SYNTHESYS+ with partners consisting of researchers and staff members of several museums and herbaria across Europe and a commercial partner, Picturae (a Dutch company specialising in collections digitisation and preservation services for the cultural heritage and archival sectors).

The talk starts with a brief summary of the activities and behind the scenes planning processes that went into ensuring a smooth transition from the existing SYNTHESYS+ transnational access portal to the new ELViS system. These activities included weekly meetings, testing, bug fixing, coordinating with transnational and virtual access coordinators from different institutions, and wireframe design. The talk also focuses on specific aspects of the data elements that enabled the call and the application process with examples of using persistent identifiers for people, institutions and facilities. The concepts behind these data elements and identifiers were based on the blueprint of the DiSSCo architecture. The talk concludes with lessons learned and issues discovered and a brief look into the future plans and upcoming milestones for ELViS.
Les banques allemandes face à la crise de 2008 : le cas de la Deutsche Bank et de la BayernLB
Authors: Baudry Pierre
Published: September 2021

Nous entendons montrer à partir d’une étude du système financier allemand que l’État et les banques centrales aux États-Unis et en Europe ont aussi contribué à cette crise. Le choix de cet objet tient au fait que l’étude du système bancaire allemand permet de remettre en cause l’idée que la financiarisation seule a provoqué la crise de 2008. Il demeure en effet très régulé, soumis au contrôle de l’État et caractéristique d’un système corporatiste. L’étude du système bancaire allemand permet ainsi de mieux comprendre comment un système financier aussi conservateur et éloigné du modèle spéculatif anglo-saxon a pu être touché par la crise de 2008.
Le dénigrement de l’autre par la langue dans le foot amateur en Allemagne et en France
Authors: Koch Florian
Published: September 2021

Le dénigrement de l’autre par la langue – englobant toutes les formes de la violence verbale quotidienne (telles que de simples insultes) et permettant de tirer des conclusions sur les attitudes à l’égard de groupes – est un phénomène transnational croissant. L’objectif de cet article est donc d’analyser ce phénomène social dans le cadre du foot amateur en Allemagne et en France. Après avoir présenté le développement du modèle plurifactoriel par induction « le dénigrement de l’autre par la langue dans le foot amateur » (DALFA) dans un premier article, ce deuxième article se concentrera sur l’analyse des facteurs influençant l’évaluation de la violence verbale en général et du dénigrement de l’autre par la langue, en particulier par l’arbitre du foot amateur, par le biais de moyens statistiques descriptifs et inférentiels. En général, l’analyse met en évidence le fait que la violence verbale est utilisée fréquemment dans le football amateur, que ce soit en Allemagne ou en France. De plus, l’analyse montre l’importance majeure de la motivation individuelle de l’arbitre. En outre, communiquer tout d’abord avec les personnes impliquées est considéré comme une stratégie efficace pour juguler les conflits. Qui plus est, l’analyse montre que des personnes tierces – les entraîneurs et les parents – les rivalités traditionnelles et l’adhésion à une ligue influencent massivement l’usage de la violence verbale. De surcroît, une majorité d’arbitres de football amateur a énoncé les caractéristiques du profil type du délinquant impliqué. Ainsi, les facteurs évoqués sont très variés : un comportement irrespectueux, l’âge, le sexe, l’origine et l’éducation. Finalement, l’analyse montre que les dénigrements verbaux sont plus sévèrement sanctionnés que les simples insultes. De plus, en violation des règles, les éléments du dénigrement verbal hiérarchisés représentent un quart des cas recensés. Il est recommandé que, outre une formation continue des arbitres amateurs et la mise en œuvre cohérente des concepts de prévention de la violence élaborés par les fédérations de football, les arbitres amateurs soient sensibilisés au phénomène du dénigrement verbal et à son « idéologie de l'inéquivalence » ainsi qu’à ses expressions linguistiques dans leur ensemble.

In vitro analysis of site specific nuclease selectivity by NGS
Authors: Brondani Vincent ,   GenAccurate, Colmar, France
Published: September 2021

Nucleases currently used in genome engineering induce hydrolysis of DNA phosphate backbone in a sequence-specific manner. The RNA guided nucleases describe today are recognizing a sequence with two distinct molecular interactions: first, like a restriction endonuclease, by direct interaction between the protein and the DNA; and second, by hybridization of the guide RNA with the target DNA sequence. Here we report an in vitro assay to assess the cleavage specificity and the selectivity of the nucleases. The assay is designed using a plasmid encompassing the DNA target site degenerated at positions determined on structural feature. The results demonstrate that the Cpf1 RNA guided nuclease is highly specific for the target sequence, nevertheless its substrate selectivity is low compare to a restriction endonuclease.

Looking for the exact solutions in the form of optical solitons of nonlinear partial differential equations has become very famous to analyze the core structures of physical phenomena. In this paper, we have constructed some various type of optical solitons solutions for the Kaup-Newell equation (KNE) and Biswas-Arshad equation (BAE) via the generalized Kudryashov method (GKM). The conquered solutions help to understand the dynamic behavior of different physical phenomena. These solutions are specific, novel, correct and may be beneficial for edifying precise nonlinear physical phenomena in nonlinear dynamical schemes. Graphical recreations for some of the acquired solutions are offered.

This paper deals with introducing and investigating a new convex mapping namely, $ n $-polynomial exponentially $ s $-convex. Here, we present some algebraic properties and some logical examples to validate the theory of newly introduced convexity. Some novel adaptations of the well-known Hermite-Hadamard and Ostrowski type inequalities for this convex function have been established. Additionally, some special cases of the newly established results are derived as well. Finally, as applications some new limits for special means of positive real numbers are given. These new outcomes yield a few generalizations of the earlier outcomes already published in the literature.

Authors: Cao Hongzhe ,   Department of Mathematics, Nanchang University, Nanchang, Jiangxi 330031, China
Published: September 2021

In this paper, we prove that two admissible meromorphic functions on an annulus must be linked by a quasi-Möbius transformation if they share some pairs of small function with multiplicities truncated by $ 4 $. We also give the representation of Möbius transformation between two admissible meromorphic functions on an annulus if they share four pairs of values with multiplicities truncated by $ 4 $. In our results, the zeros with multiplicities more than a certain number are not needed to be counted if their multiplicities are bigger than a certain number.

In this study, we use quantum calculus to prove Hermite-Hadamard and Ostrowski type inequalities for s-convex functions in the second sense. The newly proven results are also shown to be an extension of comparable results in the existing literature. Furthermore, it is provided that how the newly discovered inequalities can be applied to special means of real numbers.
Inferring Inequality With Home Production
Authors: Boerma Job , Karabarbounis Loukas
Published: September 2021

We revisit the causes, welfare consequences, and policy implications of the dispersion in households' labor market outcomes using a model with uninsurable risk, incomplete asset markets, and home production. Allowing households to be heterogeneous in both their disutility of home work and their home production efficiency, we find that home production amplifies welfare‐based differences, meaning that inequality in standards of living is larger than we thought. We infer significant home production efficiency differences across households because hours working at home do not covary with consumption and wages in the cross section of households. Heterogeneity in home production efficiency is essential for inequality, as home production would not amplify inequality if differences at home only reflected heterogeneity in disutility of work.
Using the Sequence‐Space Jacobian to Solve and Estimate Heterogeneous‐Agent Models
Authors: Auclert Adrien , Bardóczy Bence , Rognlie Matthew , Straub Ludwig
Published: September 2021

We propose a general and highly efficient method for solving and estimating general equilibrium heterogeneous‐agent models with aggregate shocks in discrete time. Our approach relies on the rapid computation ofsequence‐space Jacobians—the derivatives of perfect‐foresight equilibrium mappings between aggregate sequences around the steady state. Our main contribution is a fast algorithm for calculating Jacobians for a large class of heterogeneous‐agent problems. We combine this algorithm with a systematic approach to composing and inverting Jacobians to solve for general equilibrium impulse responses. We obtain a rapid procedure for likelihood‐based estimation and computation of nonlinear perfect‐foresight transitions. We apply our methods to three canonical heterogeneous‐agent models: a neoclassical model, a New Keynesian model with one asset, and a New Keynesian model with two assets.
Economic Predictions With Big Data: The Illusion of Sparsity
Authors: Giannone Domenico , Lenza Michele , Primiceri Giorgio E.
Published: September 2021

We compare sparse and dense representations of predictive models in macroeconomics, microeconomics, and finance. To deal with a large number of possible predictors, we specify a prior that allows for both variable selection and shrinkage. The posterior distribution does not typically concentrate on a single sparse model, but on a wide set of models that often include many predictors.
LEAF COLOR SEGMENTATION AND POT VOLUME INFLUENCE ON THE CO2 ABSORPTION EFFICIENCY IN TWO COMMON GREEN-WALL PLANTS
Authors: Agra Har’el , Uni Daphna , Horwitz Rael , Klein Tamir , Blaustein Leon
Published: September 2021

Green walls can improve indoor air-quality by reducing concentrations of carbon dioxide (CO2) and other air pollutants. Our study focused on the spider plant, Chlorophytum comosum, and devil’s ivy, Epipremnum aureum, both common green-wall plants that have been found to be efficient CO2 absorbers. Both species have multiple variants with varying degrees of leaf green-white segmentation. Since photosynthesis depends on the concentration of leaf chlorophylls, we hypothesized that green variants are more efficient carbon absorbers than green-white variants. In addition, we tested the hypothesis that the photosynthetic rate of plants is affected by pot volume, as suggested by previous studies. We used a portable gas exchange system to determine the rate of photosynthesis of the study plants. No evidence was found for better photosynthetic performance in the green vs. green-white variants of each species. In fact, our results suggest the opposite. It was observed that a spider plants assimilated carbon more efficiently when grown in a larger pot volume. In conclusion, our study shows that in terms of carbon assimilation, green-white variants of spider plants are the better choice for indoor green walls. Their efficiency can be improved dramatically by increasing pot volume.
ASSESSMENT OF AIR CHANGE EFFECTIVENESS AND THERMAL COMFORT IN A NATURALLY VENTILATED KITCHEN WITH INSECT-PROOF SCREEN USING CFD

Published: September 2021

Many dwellings in warm-humid climates attain a comfortable environment by natural ventilation. The opening of exterior windows for ventilation allows the entry of insects along with the breeze. As a remedy, occupants install insect-proof screens on windows resulting in reduced airflow into the interior. This study attempts to evaluate the air change effectiveness and thermal comfort in a residential kitchen with insect-proof screens. A kitchen with insect-proof screens on the windows is compared with a case without insect-proof screens. Numerical simulation was conducted using ANSYS Fluent 2019 R2. The insect-proof screen is modelled as a porous media. The air velocity and temperature measurements were validated by measurements in a real scenario. The presence of insect-proof screens reduced the air velocity inside the space by 82%. However, the airflow pattern in the case with screens was more uniformly distributed. The mean age of the air was considerably higher in the case with insect-proof screens, which in turn resulted in a reduced ACE. The presence of an insect-proof screen resulted in a Predicted Mean Vote (PMV) of 2.79 indicating a ‘hot’ sensation, whereas in the other case, the comfort vote is only 1.93 indicating a ‘warm’ sensation. The presence of insect-proof screens on windows reduced the air velocity and ventilation efficiency, contributing to increased thermal discomfort in the kitchen.
THE LEED-COMMERCIAL INTERIORS (V4) PROJECTS IN CALIFORNIA
Authors: Pushkar Svetlana
Published: September 2021

This study analyzed the Leadership in Energy and Environmental Design for Commercial Interior Certified, Silver, and Gold projects version 4.0 (LEED-CIv4) in California for the period 2015‒2020. Nonparametric tests were used to assess category and credit achievement, i.e., the difference between possible and achieved points and the correlation between associated credits. The results show that most of the credits in the location and transportation category and the indoor environmental quality categories had a high level of achievement, a few credits in the energy and atmosphere and materials and resources categories had a high level of achievement, and all of the credits in the water efficiency category had a low level of achievement. Some associated credits, such as surrounding density and quality transit, had a high level of achievement and a positive correlation, whereas other associated credits, such as life-cycle impact reduction and environmental product declarations, had a low level of achievement and a positive correlation. If LEED-CIv4 credits meet the requirements of the California Green Building Standards Code 2016 (CGBSC 2016), then these credits typically have a medium/high level of achievement. If LEED-CIv4 credits exceed the requirements of CGBSC 2016, then these credits have a low level of achievement. Therefore, to improve the next version of LEED-CI, it is necessary to improve the local green codes.
Collaboration chercheur didacticien/enseignant et choix de l’enseignant en situation scolaire : une étude de cas en sciences de la Terre
Authors: Ravachol Denise Orange
Published: September 2021

Dans l’exercice de la classe, les choix de l’enseignant ne s’ajustent pas exactement à ceux qu’ils ont préalablement envisagés, même lorsque ceux-ci résultent de collaborations avec des didacticiens. Cela force à étudier de plus près ce qui organise la pratique enseignante. Nous le faisons en terminale scientifique (grade 12) pour deux enseignants travaillant le problème du fonctionnement d’une zone de subduction. Nous privilégions l’angle de la construction de savoirs scientifiques par problématisation, auquel souscrit l’équipe constituée par ces enseignants et deux didacticiens. Nous montrons que les collaborations enseignants-chercheurs portent les enseignants à faire problématiser leurs élèves mais que cette problématisation reste superficielle, fragmentée, et prompte à être brutalement abandonnée pour une logique de tri de la bonne solution. Les contraintes de la forme scolaire et l’épistémologie dominante de la communauté enseignante semblent déterminantes dans ces changements de régime.
REFLEXÕES SOBRE OS IMPACTOS DE DISCURSOS RACISTAS NA RELAÇÃO ENTRE A POPULAÇÃO NEGRA E O CONHECIMENTO ESCOLAR
Authors: Santos Gabriel Gustavo dos , Vale Rosiney Aparecida Lopes do
Published: September 2021

Este artigo tem como objetivo refletir acerca do sujeito negro e a sua relação com o saber escolar. Para tal, partimos de uma pesquisa bibliográfica com intuito de discutir sobre o modo como os discursos pejorativos sobre a população negra, presentes nas mídias e nos ambientes escolares, impactam na forma como ela se relaciona com o saber escolar. Para tanto, escolhemos o texto literário Lembrança das lições (1996), de Cuti, pseudônimo do escritor Luiz Silva, para servir como elemento deflagrador dessa problemática, uma vez que ele consegue exemplificar alguns dramas comumente vivenciados por esse grupo dentro da escola. Nesse sentido, concluímos que muitos discursos depreciativos sobre a população negra brasileira, com ampla difusão na escola, podem servir de entrave na relação que eles estabelecerão com o saber escolar, impedindo, dessa forma, que desenvolvam suas potencialidades por meio da educação formal.

Busca-se, por meio de imagens de momentos com os docentes e os discentes de uma Licenciatura em Educação do Campo, apresentar os sentidos, os significados, os tempos e os espaços presentes em momentos da mística. Considera-se que esses momentos são necessários à coletividade e à formação da militância para futuros professores da Educação do Campo que atuarão em escolas do campo.
DIDACTIQUE PROFESSIONNELLE (DIDAPROF)
Authors: Alves Francisco Regis Vieira
Published: September 2021

L'activité professionnelle développée dans le travail de l'enseignant ne peut être considérée hermétiquement comme un ensemble de tâches spécialisées requises par un établissement scolaire. D'autre part, lorsque nous observons l'activité de l'enseignant, du point de vue cognitiviste, un large répertoire de connaissances est élaboré et incorporé face aux problèmes complexe inhérents à l'exercice de l'activité. Ainsi, comme objectif principaux du travail, d’un point de vue élaboré par la Didactique Professionnelle, nous présentons quelques éléments qui nous permettent de comprendre l’activité et l’apprentissage du professeur de mathématiques face à la résolution de tâches professionnelles. Ainsi, la notion de situation de travail conduit à une polarisation des activités de modélisation visant à enseigner les mathématiques et à identifier certaines entités théoriques, dont la nature cognitive révèle une compréhension du fonctionnement de l'action de l'enseignant, qu'il s'agisse d'un enseignant débutant en mathématiques ou expérimenté.
