В данной статье охарактеризованы основные аспекты изучения глаголов движения в курсе русского языка как иностранного, а также приведены дидактические материалы, которые можно использовать для освоения названной лексико-семантической группы глаголов обучающимися. Актуальность настоящего исследования обусловлена прежде всего трудностью системы русского глагола, обладающего самой богатой парадигмой. Необходимость эффективного освоения русской глагольной системы особенно возрастает при изучении русского языка как иностранного (далее - РКИ). В статье представлен структурный и семантический анализ глаголов движения, а также раскрыты их синтагматические свойства. Для облегчения знакомства с русскими глаголами движения наряду с теоретическими упражнениями в методике преподавания РКИ активно используются упражнения в игровой форме, грамматические рифмовки, имитативные задания и т. п. Они позволяют иностранным обучающимся в ненавязчивой форме закрепить изучаемую теоретическую информацию, активизируют совместную речевую деятельность обучающихся, в рамках актуального в методике преподавания РКИ функционально-коммуникативного подхода дают возможность совершенствовать полученные речевые навыки и грамматические умения.

This article describes the main aspects of studying verbs of movement in the course of Russian as a Foreign Language, and also provides didactic materials that can be used for mastering the named lexical and semantic group of verbs by students. The relevance of this study is primarily due to the difficulty of the Russian verb system, which has the richest paradigm. Russian as a Foreign Language (hereinafter referred to as RFL) is especially necessary for the effective development of the Russian verb system. The article presents a structural and semantic analysis of verbs of movement, as well as their syntagmatic properties. To facilitate acquaintance with the Russian verbs of movement, along with theoretical exercises, the teaching methodology of RFL actively employs exercises in the form of a game, grammatical rhyming, imitative exercises, etc. They allow foreign students to consolidate the studied theoretical information in an unobtrusive form, activate the joint speech activity of students, within the framework of the functional and communicative approach that is relevant in the teaching methodology of RFL, they make it possible to improve the acquired speech skills and grammatical skills.
"Matekoane ke bophelo" Cannibis is Life: Marginality and survival, a historical analysis of illicit cannabis production by the communities of Mokhtlong District of Lesotho
Authors: Chitofiri Kudakwashe
Published: November 2021

 This study examines the evolving historical, geopolitical and economic context of illicit cannabis cultivation by the marginalised highlands communities of Mokhotlong district of Lesotho. Mokhtlong is one of the most impoverished districts of Lesotho with a population that has historically operated on the margins of the state and SouthAfrica as either providers of cheap sheep products to the rest of Lesotho or as suppliers of cheap labour to the mines in SouthAfrica. It considers the implications of the supply of cannabis to mainly the Gauteng metropolitan area in South Africa to the Mokhotlong district’s inhabitants’ state of marginalisation. Historically, cannabis production in the highlands resulted in a reproduction of the asymmetrical relations between and inside the metropolitan and mountain areas of both countries. Coalitions of actors merged from these new relations that the cultivation produced, and as such, this article should be analysed as an assemblage in which three distinct scales of territorialities were clashing or cooperating with each other. The article argues that the irregular migrants from Lesotho to South Africa took advantage of the fluctuations of their legal status as they moved between South Africa and Lesotho and the fluidity of the movement across the mountainous border to the migrants and smugglers to traffic cannabis across Lesotho into South Africa. In essence, the article makes the bold claim that cannabis production was one of the key ways in which the borderland communities of Mokhtlong dealt with their economic and social marginalisation.
Properties of a Previously Unidentified Instrumental Signature in Kepler/K2 That was Confused for AGN Variability

Published: November 2021

The Kepler satellite potentially provides the highest precision photometry of active galactic nuclei (AGNs) available to investigate short-timescale optical variability. We targeted quasars from the Sloan Digital Sky Survey that lie in the fields of view of the Kepler/K2 campaigns. Based on those observations, we report the discovery and properties of a previously unidentified instrumental signature in K2. Systematic errors in K2, beyond those due to the motion of the detector, plague our AGNs and other faint-target, guest observer science proposals. Weakly illuminated pixels are dominated by low-frequency trends that are both nonastrophysical and correlated from object to object. The instrumental signature lags in time as a function of radius from the center of the detector, crossing channel boundaries. Thus, systematics documented in this investigation are unlikely to be due to Moiré noise, rolling band, or pointing jitter. A critical clue to understanding this instrumental systematic is that different targets observed in the same channels of Campaign 8 (rear facing) and Campaign 16 (forward facing) have nearly identical light curves after time reversal of one of the campaigns. We find evidence of temperature trends that also reverse according to the Sun–spacecraft field orientation and that may dominate the systematics. These temperature variations are larger in K2 than in the nominal Kepler mission and strongly support our hypothesis of temperature-driven focus changes. Further characterization of this signature is crucial for rehabilitating K2 data for use in investigations of AGN light curves.
On the Importance of Wave–Planet Interactions for the Migration of Two Super-Earths Embedded in a Protoplanetary Disk
Authors: Cui Zijia , Papaloizou John C. B. , Szuszkiewicz Ewa
Published: November 2021

We investigate a repulsion mechanism between two low-mass planets migrating in a protoplanetary disk, for which the relative migration switches from convergent to divergent. This mechanism invokes density waves emitted by one planet transferring angular momentum to the coorbital region of the other and then directly to it through the horseshoe drag. We formulate simple analytical estimates, which indicate when the repulsion mechanism is effective. One condition for a planet to be repelled is that it forms a partial gap in the disk and another is that this should contain enough material to support angular momentum exchange with it. Using two-dimensional hydrodynamical simulations, we obtain divergent migration of two super-Earths embedded in a protoplanetary disk because of repulsion between them and verify these conditions. To investigate the importance of resonant interaction, we study the migration of planet pairs near first-order commensurabilities. It appears that proximity to resonance is significant but not essential. In this context we find repulsion still occurs when the gravitational interaction between the planets is removed, suggesting the importance of angular momentum transfer through waves excited by another planet. This may occur through the scattering of coorbital material (the horseshoe drag), or material orbiting close by. Our results indicate that if conditions favor the repulsion between two planets described above, we expect to observe planet pairs with their period ratios greater, often only slightly greater, than resonant values or possibly rarity of commensurability.
The Nonrelaxation of Magnetic Field Lines in Solar Wind Magnetic Reconnection Exhausts

Published: November 2021

We present a case study using data from multiple spacecraft and statistics from the ACE spacecraft to investigate the relaxation of reconnected magnetic field lines in solar wind magnetic reconnection exhausts, which constitute one of the two outflow regions resulting from magnetic reconnection, and which are often characterized by a plasma jet, magnetic strength depletion, and density and temperature enhancements. The normal magnetic fractions (∣B

n
/B∣) of the reconnection exhausts are used to indicate the degrees of relaxation of the magnetic field lines. 97 out of 98 reconnection exhausts have a relatively small ∣B

n
/B∣ (<0.3), while only one exhaust associated with a relatively small interplanetary coronal mass ejection has a large ∣B

n
/B∣ of 0.85. This result demonstrates the nonrelaxed nature of reconnected magnetic field lines in solar wind, due to the open boundary condition. As a consequence, the magnetic tension of such nonrelaxed magnetic field lines can accelerate the local plasma to produce the observed jet within the reconnection exhaust. Our results support the understanding that most solar wind reconnection exhausts are probably initiated near the Sun, where the plasma beta is low, and that they are not ongoing when they are observed at 1 au, because of the solar wind expansion from near the Sun to 1 au.
Modeling Radio Recombination in MWC 349A. I. Saturation Properties

Published: November 2021

Strong nonlocal thermodynamic equilibrium recombination line emission from the envelope of MWC 349A has been studied observationally and theoretically and has been used to derive information about the physical and kinematic properties of the circumstellar environment around this object. In this paper, we construct a detailed model of radiative transfer of the commonly observed maser lines H26α and H30α in MWC 349A, specifically taking into account the effect of maser saturation. The envelope is modeled as a combination of an ionized Keplerian rotating disk and a disk wind expanding at a velocity of 60 km s−1. Our modeling results show that millimeter-line H26α is significantly affected by the saturation effect. The line intensity is predicted to be greatly reduced in comparison with previous models which ignore the saturation effect. The H30α maser is predicted to be unsaturated. Our model shows that the predicted intensity and line shape are in agreement with observations. The predicted position–velocity diagrams are also consistent with observations and the interpretation that the H26α maser appears at smaller radii in comparison to the H30α maser. We also emphasize that the wind component is important in shaping the line profiles of the recombination masers.

Published: November 2021

Fast radio burst (FRB) dispersion measures (DMs) record the presence of ionized baryons that are otherwise invisible to other techniques enabling resolution of the matter distribution in the cosmic web. In this work, we aim to estimate the contribution to FRB 180924 DM from foreground galactic halos. Localized by ASKAP to a massive galaxy, this sightline is notable for an estimated cosmic web contribution to the DM (DMcosmic =220 pc cm−3), which is less than the average value at the host redshift (z = 0.3216) estimated from the Macquart relation (280 pc cm−3). In the favored models of the cosmic web, this suggests few intersections with foreground halos at small impact parameters (≲100 kpc). To test this hypothesis, we carried out spectroscopic observations of the field galaxies within ∼1′ of the sightline with VLT/MUSE and Keck/LRIS. Furthermore, we developed a probabilistic methodology that leverages photometric redshifts derived from wide-field DES and WISE imaging. We conclude that there is no galactic halo that closely intersects the sightline and also that the net DM contribution from halos DMhalos < 45 pc cm−3 (95% c.l.). This value is lower than the DMhalos estimated from an “average” sightline (121 pc cm−3) using the Planck ΛCDM model and the Aemulus halo mass function and reasonably explains its low DMcosmic value. We conclude that FRB 180924 represents the predicted majority of sightlines in the universe with no proximate foreground galactic halos. Our framework lays the foundation for a comprehensive analysis of FRB fields in the near future.
Evaluation of the antifungal activity of marine actinomycetes isolates against the phytopathogenic fungi Colletotrichum siamense KA: A preliminary study for new antifungal compound discovery

Published: November 2021

Marine actinomycetes are being explored to discover potential actinomycetes that produce antifungal compounds. In a previous study, marine actinomycetes isolates from the mangrove ecosystem were found to inhibit growth of the phytopathogenic fungi Colletotrichum siamense KA. In this study, the three of these isolates with the highest antagonistic activity—SM11, SM14, and SM15—were evaluated for their antifungal activity using antibiosis assay. The fermentation was performed in SCB:PDB medium (1:1) for 6, 9, and 12 days. The results showed that SM14 was the strongest potential isolate; it inhibited the growth of C. siamense KA on average up to 64.90% for 12 days on PDA filtrate medium. Molecular identification showed SM14 was closely related to Streptomyces sanyensis, but had differences in morphological and biochemical characteristics compared to SM11 or SM15. This indicated that the three isolates were different strains and may challenge further research on identifying and analyzing their antifungal compounds.
Jeux de masques. L’institutionnalisation ministérielle inachevée de l’environnement
Authors: Villalba Bruno
Published: November 2021

La variation des noms du ministère chargé de l’écologie permet de saisir la difficile institutionnalisation de cette thématique. Elle traduit le positionnement ambigu des élites dirigeantes face à l’environnement et de leurs hésitations dans la construction d’un appareil d’État dédié à la prise en charge de cet enjeu. L’article tente de montrer que la construction institutionnelle de l’environnement, loin de constituer un élément perturbateur, contribue à la poursuite d’une politique de croissance et de développement. Il est alors subordonné à une politique cornucopianiste (représentation prométhéenne de l’action politique, technologique et croissantiste). Doté d’une autonomie décisionnelle réduite, ce ministère devient le supplétif des autres politiques jugées prioritaires (aménagement, production industrielle et agricole…). Désormais, sous couvert de développement durable puis de transition écologique, il s’agit de poursuivre le développement d’une croissance verte, qui contribue à reléguer l’urgence écologique.

Published: November 2021

Dans le contexte pandémique actuel, les pratiques professionnelles se voient bouleversées. La formation tient un rôle essentiel pour répondre à cette urgence, et les nouvelles technologies une place de choix pour répondre aux besoins à distance. Cette recherche s’inscrit dans un projet de recherche visant la conception d’un serious game de formation managériale. Considérant que ce type de support ne se suffit pas à lui-même, nous avons construit un dispositif d’accompagnement humain s’appuyant sur les situations simulées virtuellement. Fondé sur le processus de réflexivité essentiel à l’activité managériale (Delavallée, 2006), il est conçu de manière longitudinale et sur des allers-retours entre expériences simulées et réelles et entre des espaces collectifs et individuels pour déclencher le co-développement. L’ensemble du dispositif de formation a permis aux managers participants de déconstruire individuellement des savoirs mobilisables dans, par et sur l’action et de les reconstruire collectivement sous trois formes : humaines, matérielles et symboliques.

It is widely agreed that properly establishing a sustainable supply chain strategy to yield competitive advantages is essential for business enterprises, and a number of research papers on sustainable supply chains have been produced over the last two decades. However, many past studies on sustainable supply chain strategies emphasized either classification schemes or various coordination mechanisms, and few of them have focused on an integrated framework for sustainable supply chains. Therefore, the objective of this study is to develop a strategic framework for the sustainable supply chain management. The study is based on the abductive reasoning process through literature review to establish a strategic framework which is ranked through grey relational analysis (GRA). The weighted data of various strategies collected from the elite interview prove to be comprehensive and evaluable, so it can create values for supply chain members in practice. The results further suggest that each sustainable supply chain in different fields can select the best combination of strategies through GRA to constantly facilitate performance of sustainability. The main contribution is the submission of a strategic framework which makes up the insufficiency of past research papers lacking an integrated strategic framework. At the same time, the proposed strategic framework has also been illustrated through a case study.

Authors: Cabana Mélanie , Bédard Denis
Published: November 2021

Depuis 2009, les enseignants de l’Université de Sherbrooke et d’autres établissements sont de plus en plus nombreux à solliciter la formation offerte au Microprogramme de 3e cycle en pédagogie de l’enseignement supérieur (MPES). À travers cette formation, ils sont invités à se plonger au cœur d’une démarche réflexive centrée sur l’apprentissage étudiant. Quels sont les impacts de cette « formation longue »? Notre étude a pour objectif de mesurer les incidences de ce programme de formation sur la motivation et les stratégies d’apprentissage des étudiants ayant suivi les cours d’enseignants formés par le MPES. Les données perceptuelles recueillies auprès de 252 étudiants inscrits dans six programmes de formation différents (enseignement préscolaire et primaire, enseignement collégial, politiques appliquées, chimie, informatique et génie) montrent que les enseignants formés à la pédagogie de l’enseignement supérieur ont proposé des exposés et des activités favorisant le maintien de la motivation de leurs étudiants tout au long du semestre. Les données révèlent également que les enseignants ont aussi utilisé des pédagogies actives favorisant l’usage de stratégies de contextualisation, de sélection de l’information principale et de régulation chez leurs étudiants. De façon plus particulière, il ressort que les enseignants issus des programmes en enseignement préscolaire et primaire, de même qu’en enseignement collégial ont contribué à rehausser significativement la motivation de leurs étudiants. De plus, les enseignants de ces programmes ont favorisé une augmentation significative de la fréquence d’utilisation de stratégies d’apprentissage variées en contextualisant leurs exposés et en proposant des pédagogies actives.

Published: November 2021

Ancient archaeological sites contain numerous pottery objects that suffered from different deterioration factors. This study aims to use different analytical methods to study the chemical and mineralogical composition and identification of deterioration aspects of some ancient Egyptian pottery jars from Saqqara excavation. Thus, to explain the deterioration factors' mechanisms and apply the proper conservation methods to the deteriorated pottery jars. AutoCAD, digital microscope, scanning electron microscope (SEM-EDX), and x-ray diffraction (XRD) were used to clarify the preservation states of pottery jars. The results of the investigation revealed that the selected jars suffered from different cracks, salts crystallization, some surface black spots, separation of the slip layer, and heterogeneity in the grains size. XRD analysis revealed that quartz, diopside, illite, muscovite, orthoclase, anorthite, and hematite are the main components of the jars. SEM-EDX analysis showed high concentrations of chlorides and sulfate salts, besides the presence of manganese oxide. Different treatments were performed for the pottery jars include mechanical and chemical cleaning. Additionally, the completion process was done by using a mixture of dental gypsum with grog. Moreover, the consolidation process was achieved by using paraloid B-72.

Published: November 2021

The effects of corrosion on the reinforced concrete structure due to carbonation affect its operation life. The research work considers a major critical component causing global warming as it studies the links between reinforced concrete deterioration mechanisms and anthropogenic carbon aerosol (black carbon soot) emissions in the atmosphere. Experimental tests were carried out to study the effect of carbonation caused by the emission of black carbon soot on mechanical properties and durability of reinforced concrete. Mass concrete and reinforced concrete prepared with Ordinary Portland cement (OPC) in water/cement ratios ranging from 0.45 to 0.65 were used to produce concrete samples. Compressive strength tests, tensile strength test, and carbonation depth tests were carried out on concrete to determine its level of deterioration following the carbonation effect. The carbonation chamber was prepared with carbon soot of different concentrations to simulate different levels of black carbon soot in the atmosphere. Results showed that concrete compressive strength was not totally affected by carbonation, but there was reduction in the tensile strength of reinforcing steel. The carbonation depth was observed to progress deeper into the concrete with a longer duration of exposure to carbonation agents in the chamber. The result of this study will serve as a guide during concrete installations.

Published: November 2021

Abstract-This paper proposes a novel hybrid technique that combines the priority list (PL) with the binary crow search algorithm (BCSA) for solving the unit commitment problem (UCP). Firstly, the PL method aims to sort the generating units in ascending order according to their average full load costs which are the total costs that are computed at the maximum generation outputs. Secondly, the BCSA is developed and employed to search for the optimal schedule of the generating units to face the next hourly demand with minimum total operating costs that are related to the optimal power generation schedule at certain loading level. BCSA is a new meta-heuristic optimizer, which is featured of the crow's intelligence. It has only two adjustable parameters that make its implementation very simple and easy compared to other optimization techniques. Its effectiveness and feasibility were confirmed by 4, 10, and 26-unit systems and the results are compared with those obtained by GA, PSO, APSO, and BDE. The simulation results demonstrate the capability of the proposed PLBCSA in solving the UC problem with good convergence rate compared with the previous methods in the literature. Around of 2-4% reduction in the total costs is achieved using the proposed PLBCSA for the 26-unit test system compared with GA, PSO and the implemented PL-BPSO solutions.
Influences of Zero Mass Flux and Active Conditions on the Predictions of Double Dispersion and Double Diffusive Boundary Layer in Darcy/Non Darcy Nanofluid Flow

Published: November 2021

Free convective of nanofluid inside dispersive porous medium adjacent to a vertical plate under the effects of the zero mass nanoparticles flux condition and the thermal and solutal dispersions is studied. Buongiorno's model revised is used considering Darcy and non Darcy laminar flows, and isothermal or convective flux outer the wall. Dimensionless governing equations formulated using velocity, temperature, concentration and nanoparticle volume fraction have been solved by finite difference method that implements the 3-stage Lobatto collocation formula. The numerical data obtained with semi or full dispersions cases are compared to predictions made using the non dispersive porous medium. Taking into account the dispersions, the influence of the zero mass nanoparticles flux condition is examined to test the validity of the control active nanoparticle assumption. It is found mainly that the thermal transfers can reach more than 100% in connection with the case where of a semi-dispersion of the porous medium is applied. Realistic condition, i.e. zero mass flux should be addressed for the heat transfer rate rather than the mass transfer rate, discovered markedly different to the active condition. This signifies the importance of considering the zero nanoparticles mass flux and dispersions in the performance characterization of nanofluid flow in porous media.
Performance of Recycled Aggregate Concrete Made with Waste Refractory Brick
Authors: Khattab Mohammed , Hachemi Samya
Published: November 2021

Concrete containing recycled aggregates have different properties from concrete containing natural aggregates. This work investigates, firstly, the possibility of using recycled refractory bricks (RBA) as coarse aggregate for concrete, and secondly, finds the ideal replacement percentage of natural coarse aggregate (NCA) by RBA. For this, an experimental study was carried out to assess the physical and mechanical properties of concrete produced with the partial and total replacement of NCA by RBA. Two types of RBA from two different sources were used, RBA-1 obtained from the grinding of new refractory bricks and RBA-2 obtained from refractory bricks used in the furnace recovered from the cement plant. For each type of RBA, two concretes with water/cement (w/c) ratios of 0.59 and 0.38 were tested. These concretes were evaluated by density, water porosity, ultrasonic pulse velocity (UPV) and compressive strength, and compared to those obtained on conventional concretes. The results obtained show that concrete can be manufactured using RBA. Concrete containing 20% ​​RBA shows good quality compared with conventional concrete.
Autonomy vs. beneficence. A bioethical inquiry for Covid-19 mandatory vaccination
Authors: Menniti Diego
Published: November 2021

Lately, the public discussion around mandatory vaccination has been an intensely enliven one. On the one hand, there are those who argue for the effectiveness of vaccination and demand that all procure it in order that all be immunize and that the threat of COVID-19 be minimize. On the other hand, there are those who are troubled about getting the vaccine and claim that mandatory vaccination is an infringement on their individual Autonomy. Furthermore, there are those who refuse vaccination for faith-based reasons and thus invoke religious exemption. The paper offers a moral analysis about the conflict between Mandatory Vaccination, supposed to be for the good of the community, and individual Autonomy. It clarifies why there are no moral basis for mandatory vaccination nor for religious exemption.

Published: November 2021

Context

Concussion underreporting leads to delays in diagnosis and treatment, prolonging recovery time. Athletes' self-reporting of concussion symptoms, therefore, reduces risk.

Objective

To evaluate the effectiveness of 3 concussion-education programs in improving concussion-reporting intention.

Design

Randomized controlled clinical trial.

Setting

Three high schools in California.

Patients or Other Participants

A total of 118 male football players (age = 14.88 ± 1.19 years).

Intervention(s)

Participants were randomly assigned to receive concussion education via CrashCourse (CC), Centers for Disease Control and Prevention (CDC) video education materials (CDC-Vi), or CDC written education materials (CDC-Wr).

Main Outcome Measure(s)

The primary outcome was concussion-reporting intention, which was assessed at baseline, immediately after education, and at 1-month follow-up. Secondary outcomes were concussion knowledge, concussion-reporting attitudes, perceived concussion-reporting norms, and perceived behavioral control.

Results

Across all education formats, a total sample of athletes improved in concussion-reporting intention at immediate and 1-month follow-ups (mean improvements = 6.8% and 11.4%, respectively; F4,224 = 11.1, P < .001). Similar findings were observed across all education formats in secondary analyses examining knowledge, attitudes, and perceived behavioral control. However, we noted differences in concussion-reporting intention by education format and time (F4,224 = 2.8, P = .03). Post hoc analysis showed that athletes who received CC had increased concussion-reporting intentions at immediate and 1-month follow-ups (baseline = 4.7, immediate follow-up = 6.1, 1-month follow-up = 6.0; F16,61.1 = 6.1, P = .007) compared with increases only at 1-month follow-up for CDC-Vi (baseline = 4.3, immediate follow-up = 5.2, 1-month follow-up = 5.8; F1.6,61.6 = 8.4, P = .001) and no improvement for CDC-Wr (P = .10). Secondary analyses indicated differences between CC and both CDC interventions in concussion knowledge and attitudes at immediate and 1-month follow-ups. We identified no differences in perceived behavioral control among interventions (F4,216 = 0.2, P = .93) or perceived concussion-reporting norms across (F4,224 = 0.3, P = .73) or among (F4,224 = 1.7, P = .15) interventions.

Conclusions

All athletes exhibited an improved intent to report concussions, increased concussion knowledge, better concussion attitudes, and more perceived behavioral control at both immediate and 1-month follow-ups. However, athletes randomized to receive CC reported a greater intent to report concussion, more knowledge, and improved concussion-reporting attitudes when compared with those who received CDC-Vi and CDC-Wr.

A Rare Case of Duplicated Appendix Presenting as Acute Appendicitis
Authors: Damera Vineeth Venkata , Rathlawath Shiva Kumar
Published: November 2021

Appendiceal duplications are one among the rare congenital anomalies of the gastrointestinal tract. This is an interesting case report of a 24-year-old male who was diagnosed to have acute appendicitis. On exploration, the patient had duplicated appendix; both were inflamed and adherent to each other with separate base. Appendectomy was performed on both, and histopathology confirmed appendicitis in both appendices. Duplicated appendix represents a challenging clinical scenario in case of right iliac fossa pain. Surgeons should be aware of this rare congenital anomaly to avoid missing the duplication that may result in serious life-threatening consequences.

Cichoń’s diagram lists twelve cardinal characteristics (and the provable inequalities between them) associated with the ideals of null sets, meager sets, countable sets, and

It is consistent that all entries of Cichoń’s diagram are pairwise different (apart from

\operatorname{add}\mathcal{M}

and

\operatorname{cof}\mathcal{M}

, which are provably equal to other entries). However, the consistency proofs so far required large cardinal assumptions.

In this work, we show the consistency without such assumptions.
Uniform energy distribution in a pattern-forming system of surface charges
Authors: Bellova Katarina , Julia Antoine , Otto Felix
Published: November 2021

We consider a variational model for a charge density

u\in\{-1,1\}

on a (hyper)plane, with a short-range attraction coming from the interfacial energy and a long-range repulsion coming from the electrostatic energy. This competition leads to pattern formation. We prove that the interfacial energy density is (asymptotically) equidistributed at scales large compared to the scale of the pattern. We follow the strategy laid out by Alberti, Choksi and Otto (2009). The challenge comes from the reduced screening capabilities of surface charges compared to the volume charges considered in the aforementioned work.

This study aimed to determine factors related to misconceptions about human immunodeficiency virus (HIV) transmission and the stigma against people living with HIV/AIDS (PLWHA) in IndonesiaMETHODS: This cross-sectional study used secondary data from the 2017 Indonesia Demographic and Health Survey (IDHS). The sample was women and men aged 17-45 years and married (n=3,023).RESULTS: Education and wealth index quintile were significantly related to misconceptions about HIV transmission. Respondents with low levels of education were more likely to have misconceptions about HIV transmission. Respondents who were in the poorest, poorer, middle, and richer quintiles of the wealth index were more likely to have misconceptions about HIV transmission than those in the richest quintile. Educational level, employment status, and wealth index quintile were predictors of stigma against PLWHA.CONCLUSIONS: There are still many Indonesian people with misconceptions about HIV transmission and stigma against PLWHA. Future studies should focus on educational programs or interventions aimed at increasing public knowledge and awareness, promoting compassion towards PLWHA, and emphasizing respect for the rights of PLWHA. These interventions are particularly important for populations who are uneducated and living in poverty.

Estos últimos años han sido muy determinante para la sociedad, a raíz de la declaración de la pandemia Covid-19, por parte de la OMS, muchas actividades se trasladaron a espacios virtuales, una de ellas es la educación, todo lo curricular se tuvo que replantear para lograr cumplir con el proceso de enseñanza aprendizaje; las instituciones de educación superior al igual que otras instituciones se vieron en necesidad de desarrollar de manera urgente, en los docentes y estudiantes, competencias digitales en las diferentes plataformas virtuales, de esto surgieron un sinnúmero de capacitaciones que les permitieran a ellos, desenvolverse en el mundo virtual enfocado en la educación. La comunicación en línea mediante las plataformas virtuales ha sido la herramienta de sostenibilidad para dinamizar la educación en tiempo de crisis sanitaria; en tal virtud surgió la interrogante ¿cómo la comunicación sincrónica y asincrónica influye en los resultados de enseñanza aprendizaje de los involucrados en el preuniversitario de la Universidad Laica Eloy Alfaro de Manabí durante el periodo 2020-2? Para este estudio se aplicó una metodología de enfoque mixto, donde lo cuantitativo sirvió en la recopilación de datos de fuente primaria, para a través del método cualitativo realizar un análisis descriptivo de la investigación planteada. Los resultados obtenidos llevaron a establecer que la educación virtual en el preuniversitario, la Uleam empleó las plataformas Moodle, Microsoft 365 y Zoom, donde docentes y estudiantes desarrollaron competencias digitales para interactuar en este proceso, no obstante, el nivel de dominio con la que utilizaban estos recursos didácticos digitales se ubica entre un nivel medio-alto, esta forma de educación y el manejo de herramientas digitales son muy necesarias e importantes para lograr un aprendizaje significativo, es por aquello que muchos estudiantes exteriorizan que los docentes deben prepararse más para que sean la guía de sus educandos.

The Bicolor Angelfish, Centropyge bicolor, is a tropical coral reef fish. It is named for its striking two-color body. However, a lack of high-quality genomic data means little is known about the genome of this species. Here, we present a chromosome-level C. bicolor genome constructed using Hi-C data. The assembled genome is 650 Mbp in size, with a scaffold N50 value of 4.4 Mbp, and a contig N50 value of 114 Kbp. Protein-coding genes numbering 21,774 were annotated. Our analysis will help others to choose the most appropriate de novo genome sequencing strategy based on resources and target applications. To the best of our knowledge, this is the first chromosome-level genome for the Pomacanthidae family, which might contribute to further studies exploring coral reef fish evolution, diversity and conservation.

A prática regular de exercício físico aliada a alimentação adequada é fundamental para bons resultados. A prática de musculação propicia aos indivíduos a perda da gordura corporal e o ganho de massa muscular. O objetivo deste foi avaliar o consumo alimentar de praticantes de musculação treinados. Foi utilizado o registro alimentar de 7 dias para a avaliação da ingestão de macronutrientes (Carboidratos, Proteínas e Lipídios), minerais (Ferro, Magnésio, Zinco e Cálcio), vitaminas (Vitamina C e Vitamina E) e fibras alimentares. Foram avaliados 26 praticantes de musculação (13 homens e 13 mulheres com 26,7 ± 4,5 anos). O consumo médio de energia foi maior nos homens (2397,2 kcal/d vs 1827,2 kcal/d, p<0,05). Não houve diferença significativa entre homens e mulheres no consumo de carboidratos (3,6 ± 1,6 g/kg/d vs 3,8 ± 1,5 g/kg/d), proteínas (1,6 ± 0,6 g/kg/d vs 1,9 ± 0,7 g/kg/d) e lipídios (1,0 ± 0,5 g/kg/d vs 1,0 ± 0,4 g/kg/d). O consumo de fibras alimentares foi inadequado em todos os indivíduos. O percentual de inadequação foi menor para as vitaminas avaliadas (Vit C e E) comparado aos minerais. Os maiores percentuais de inadequação em ambos os gêneros foram observados para o consumo de magnésio. A maioria das mulheres (76,9%) apresentou consumo inadequado de ferro. Ao contrário todos os homens consumiam ferro adequadamente. Conclui-se que a maioria dos avaliados apresentaram ingestão de energia, carboidratos, proteínas e lipídios dentro das faixas recomendadas. Por outro lado, a ingestão de fibras alimentares, minerais e vitaminas necessita ser melhorada.
Use of Nano Technology (Nano Gro) To Boost Productivity and Increase Pest Resistance in Okra Crop for Export in Southern Honduras.
Authors: Lastres Mariana Lorena
Published: November 2021

The present study reports the effect of the nanotechnology molecule “Nano Gro” on a number of agronomical variables of okra, Abelmoschus esculentus, as well as its effect on leaf miner, white fly, Bemisia tabaci, and Spodoptera larvae attacking the crop. Most initial data was taken in a trial used for the registration of Nano Gro as an agricultural amendment in Honduras, carried in a plot worked by Juan Benito Guevara, a local okra producer farming in Las Bazas, very near the city of Choluteca, next to the Choluteca river, in Southern Honduras. However, other important data was taken on plots from different local okra companies and producers in the Choluteca area.

The stimulant Nano Gro is a mixture of sulfates and elements such as Fe, Co, Al, Mg, Mn, Ni and Ag, produced at a concentration of 10-9 mol, available in the form of an oligosacharid pellet. It has OMRI certification and can be used in organic and regular agriculture. According to the Honduran distributor (Núcleo Agro), Nano Gro stimulates the plant´s natural resistance to abiotic stress, which in turn makes the plant produce growth hormones like auxins, gibberellines and cytokinines. This hormone productionmakes the use of nutrients and water more efficient, resulting in greater plant resistance, greater performance and greater quality of fruit harvested.

“Childhood Obesity its Factors, Complications and Impact on Overall Health in Children”
Authors: Khan Asma Saghir
Published: November 2021

Childhood, overweight and obesity are increasingly significant problems, and ones that are likely to endure and to have long term adverse influences on the health of individuals and populations unless action is taken to reverse the trend. A number of factors have been suggested as contributing to the development of childhood obesity. These include genetic factors, decreasing levels of physical activity, increased time spent in sedentary behavior and changes in diet. In addition, lifestyle factors, including family influences, changes in society and media advertising, have been associated with the increasing incidence of obesity and overweight in childhood. To address the problem, health care professionals should incorporate appropriate screening in their child practice. Comprehensive assessment of children who are, or who are at risk of becoming, obese is also necessary
