OPERAÇÕES SEMIOCOGNITIVAS MOBILIZADAS EM TAREFAS DE GEOMETRIA: UMA ANÁLISE COM ALUNOS MEDALHISTAS DO 8º ANO
Authors: De Campos Adilson , Moretti Méricles
Published: May 2022

O presente estudo, ao fazer uso de uma metodologia qualitativa (inscrita em um paradigma interpretativo), tem por objetivo identificar e compreender certasperações semiocognitivas (apreensões, olhares e relevância da dimensão) mobilizadas por alunos medalhistas de 8º ano na resolução de três tarefas de geometria (perímetro e área). O estudo foi realizado por meio da análise documental de três produções escritas de dois alunos do 8º ano do Ensino Fundamental. A partir da análise dos dados com suporte na Teoria das Representações Semióticas de Raymond Duval, as conclusões evidenciam uma sinergia na mobilização das apreensões (perceptiva, discursiva, operatória e sequencial), no uso de olhares não icônicos e na mudança de dimensão em que os alunos conseguem ver nas figuras, de forma proficiente, dimensões diferentes daquelas que foram, inicialmente, dadas nas tarefas.

Published: May 2022

Este estudo traz um recorte de pesquisa qualitativa que envolveu a formação inicial de professores de Matemática e teve por objetivo apresentar os resultados de um pré-teste realizado por meio de questionário com alunos da Licenciatura em Matemática. Os questionamentos propostos no pré-teste versam sobre o conhecimento e as contribuições da Metodologia Resolução de Problemas no ensino da Matemática, o papel do professor em sala de aula – considerando fatores ligados ao Contrato Didático – e se os graduandos almejam mudanças nas práticas docentes futuras, visto que conhecimentos advindos da Formação Inicial certamente influenciam na atuação do futuro professor. Como embasamento teórico, utilizamos autores que tratam da Formação Inicial (BORGES, 2004; GATTI, 2010 IMBERNÓN, 2011), do Contrato Didático (BROUSSEAU, 1986) e da Metodologia Resolução de Problemas (POLYA, 2006; ONUCHIC; ALEVATTO, 2014). Quanto à metodologia do estudo, fizemos uso de uma abordagem qualitativa sob um aspecto exploratório. Diante da análise e dos resultados, constatamos que os licenciandos, de modo geral, têm conhecimento de algumas das noções levantadas nos questionamentos, que o conhecimento ligado à Metodologia Resolução de Problemas se deve a disciplinas vivenciadas na graduação e que o papel do professor também pode ser visível quando se abordam metodologias que visem à promoção da aprendizagem, de modo que o foco não esteja centrado na transmissão de saberes, mas que professor e estudante têm igualmente funções ativas e recíprocas no processo de ensinar e aprender. Finalmente, é importante reforçar o fato de que a Formação Inicial dos professores, seja ela satisfatória ou não, interfere na qualidade da Educação, algo que, sutilmente, também deixa seus traços nos achados de nossa pesquisa.

Authors: Ilapavuluri Saicharitha , Marabathuni V Jhansi Priya , Narapusetty Naidu
Published: May 2022

In the present research work Zileuton tablets were formulated by employing compression coating technology. Initially the core tablets were prepared by using various concentrations of super disintegrates, the formulated core tablets were coated with the polymers by using compression coating technology. All the core and compress coated tablet formulations were subjected to various physical and chemical evaluation tests for core and compress coated tablets. The thickness, hardness and weight variation shown by all the tablet formulations were found within the official pharmacopoeial limits.  In vitro release of Zileuton of core tablet formulations ZF5 showed faster drug release after 15 min. Faster drug release can be correlated with the high disintegration and friability observed in this study.

Substantiation of technological parameters of equipment for application of plant protection products using multicopters
Authors: Vozhik Yu. G. , Maranda S. O. , Vitrukh P. I.
Published: May 2022

Annotation
Purpose. Improving the efficiency of field spraying and creating safe working conditions for maintenance personnel through the use of unmanned multicopters, the air jets from the propellers of which will not distort the flares of the sprayed solution of plant protection products (PPE).
Methods. The method of analysis of variable time components of agricultural units is used.
Results. Dependences of technical and operational indicators of technological equipment of a multicopter on this design and mode parameters and their rational values are received. Comparative data of multicopter and ground sprayers were obtained, which revealed the indisputable advantages of the former over the latter.
Conclusions
1. One of the successful alternatives to ground sprayers is the use of unmanned aerial vehicles – multicopters, which, unlike ground vehicles, do not need to leave in the field among the plants technological tracks that reduce up to 5 % usable area and do not depend on soil and plant height. Due to the significant high working speed in comparison with ground means (from 3 m/s to 10 m/s) and practically absence of time for turns at the end of a run (3–5 s) one multicopter with width of capture of 10–12 m, can replace ground sprayer with a width of 50 m and five times the cost.
2. The rational structural and functional scheme of the technological equipment of the multicopter for plant protection must be similar to the ground sprayers of the frame construction, on the sides of which the screws of the multicopter are installed, and between them the spraying equipment.
3. Reducing the rate of application of PPE solution from low-volume (50 l/ha) to ultra-low-volume (10 l/ha) spraying increases productivity by only 1,3 times and significant complexity of the equipment.
4. Reducing battery time during multicopter operation from 180 minutes to 10 minutes reduces performance by only 10 %.
5. For low-volume spraying, a sufficient tank capacity for the PPE solution is 30 liters.
6. To increase productivity and reduce material costs for batteries, the multicopter must be equipped with a hybrid power plant with an internal combustion engine, which will recharge the battery to drive its propellers.
7. Increasing the capacity of the tank for the solution of PPE in ground sprayers from 3000 liters to 15000 liters is not economically feasible due to a slight (up to 10 %) increase in productivity, increased soil compaction and energy consumption.
Keywords: agricultural multicopter, multicopter-sprayer, agricultural drone, liquid sprayers, ultra-low-volume spraying, parameters, modes.
Tree/Endofunction Bijections and Concentration Inequalities
Authors: Heilman Steven
Published: May 2022

We demonstrate a method for proving precise concentration inequalities in uniformly random trees on $n$ vertices, where $n\geq1$ is a fixed positive integer. The method uses a bijection between mappings $f\colon\{1,\ldots,n\}\to\{1,\ldots,n\}$ and doubly rooted trees on $n$ vertices. The main application is a concentration inequality for the number of vertices connected to an independent set in a uniformly random tree, which is then used to prove partial unimodality of its independent set sequence. So, we give probabilistic arguments for inequalities that often use combinatorial arguments.
Central Limit Theorem for the Largest Component of Random Intersection Graph
Authors: Dong Liang , Hu Zhishui
Published: May 2022

Random intersection graphs are models of random graphs in which each vertex is assigned a subset of objects independently and two vertices are adjacent if their assigned subsets are adjacent. Let $n$ and $m=[\beta n^{\alpha}]$ denote the number of vertices and objects respectively. We get a central limit theorem for the largest component of the random intersection graph $G(n,m,p)$ in the supercritical regime and show that it changes between $\alpha>1$, $\alpha=1$ and $\alpha<1$.

Membangun Semangat Anti Korupsi Melalui Ajaran Trilogi Karmaphala
Authors: Oka Widana Anak Agung Gde
Published: May 2022

The phenomenon of corruption cases is not a foreign phenomenon in Indonesia. Its existence seems to have become ingrained in the daily routine of the world of work which is increasingly being suppressed by the increasing pace of development of the necessities of life, as well as the temptation of the development of new technological innovations that are increasingly tempting. There have been many cases of corruption that have been revealed, but the emergence of corruptors is actually getting more and more caught. Of course, it is interesting to study when considering the fact that criminal and civil law verdicts have not provided a deterrent effect. There is a need for the presence of other sanctions that accompany so that corruptors are more aware of, which in this case is the cultivation of an understanding of religious sanctions. The purpose of this research is to stimulate the anti-corruption spirit of the community through understanding the teachings of Hinduism, especially through the concept of the Karmaphala Trilogy. Three issues are raised in this study: the existence of corruption, efforts to eradicate corruption and efforts to build an anti-corruption spirit through the Karmaphala Trilogy. As a type of qualitative research, the data obtained in this study were collected through library techniques and document recording. The data that has been collected is then analyzed using a qualitative descriptive technique. The results of the analysis show that corruption is a product of the life attitude of a group of people who glorify the existence of nominal finance (money) as a standard of truth. Recognizing the increasingly worrying level of extremity of corruption cases, efforts to eradicate them can no longer be carried out with ordinary steps, but extraordinary methods are needed in the form of a combination of socialization of criminal law, civil law and religious law. Building the Anti-Corruption spirit through the Karmaphala Trilogy is one alternative that can be done, through inculcating an understanding of the concept of Sancita Karmaphala, instilling an understanding of the concept of Prarabdha Karmaphala and inculcating an understanding of the concept of kryamana karmaphala to the public.

Impacts of Parents’ Exercise on Inherited Genes
Authors: Kolluru Arnav
Published: May 2022

Physical exercise is considered an essential prospect in cognition. Exercise has a lot of benefits. It increases your body HDL (good cholesterol), controls your weight, prevents heart attacks and diabetes, regulates blood pressure, strengthens your muscles, and improves mood. However, we have minimal information regarding the effects of parents’ exercise on the genes they pass down. This research paper reviews three different previous studies done on this topic. The first study is about the research done on the mice to analyze the transmission of the exercise effects of the mice fathers to offspring. The second study is the comprehensive analysis of the epigenetic changes at the molecular level in both mammalian and rodent cells. The third study is exclusively about the research on humans. Later, I presented the research design that I set up to find the answers to my questions, the potential outcomes, and further analysis of the results.
Antimicrobial Susceptibility Pattern and Virulence Genes Detection in Citrobacter freundii Isolated from Patients of a Tertiary Care Hospital, Bangladesh
Authors: Rahman Asma , Shamsuzzaman S.M. , Dola Nigha Zannat
Published: May 2022

Background:

Citrobacter freundii is an infrequent hospital acquired pathogen to cause different types of disease in clinical settings. This pathogen is associated with wide range of infections causing unpredictably high mortality rate of 30-60%.  Separation of this pathogen in health care settings is escalating and multidrug resistant strains are emerging. Therefore, this study aimed to detect antimicrobial resistance pattern and virulence genes among the isolated C. freundii.

Methods:

A total 500 samples (urine, stool, wound swab & pus, blood endotracheal aspirates and sputum) from patients with clinically suspected infections irrespective of age and sex were used in this study. Disc diffusion method was used to detect susceptibility pattern of antibiotics; colistin, tigecycline and fosfomycin susceptibility pattern was identified by minimum inhibitory concentration (MIC) method. Polymerase chain reaction (PCR) was done to detect potential virulence genes.

Results:

Among 27 isolated C. freundii, majority were resistant to amoxiclav (92.59%), trimethoprim-sulfomethoxazole (88.89%), cefotaxime and ceftazidime (85.19%) followed by ceftriaxone (81.48%), cefepime and ciprofloxacin (77.78%). MIC showed least resistance to colistin (29.63%), fosfomycin (11.11%) and tigecycline (7.41%). PCR was positive for via B gene (48.15%)   and lt-A gene (25.93%). hly A, lt, lt-h genes showed negative results.

Conclusion:

Antibiotic resistance found in this study is quite worrisome as widespread resistance is seen among the bacteria isolated from human infection. Also, virulence genes play important role in C. freundii infection.
Mapping out the Stellar Populations of IC 2602 and IC 2391
Authors: Nisak Azmain H. , White Russel J. , Yep Alexandra , Henry Todd J. , Paredes Leonardo , James Hodari-Sadiki , Jao Wei-Chun
Published: May 2022

IC 2391 and IC 2602 are important benchmarks for testing early star and planet evolution theories, both structural and dynamical, because they are the nearest open clusters with ages of ∼50 Myr. We refine membership lists for these clusters by identifying candidate members using Gaia DR2 kinematic and distance information. We identify 451 candidate members of IC 2602 and 350 candidate members of IC 2391. If confirmed, this would increase the known populations of these clusters by 275% and 130%, respectively. We use CHIRON on the CTIO/SMARTS 1.5 m telescope via fiber mode which yields a resolution of 27,400 to acquire high-resolution spectra of 26 new candidate cluster members brighter than G = 13 magnitude, as well as an additional 12 previously known members. Measures of lithium, Hα, stellar properties (T
eff, log(g), [Fe/H]), radial velocities, and

v
sin
i

values from these spectra are used to confirm cluster membership. We find that 37 of 38 stars we observe are bona fide cluster members, of which four are new candidate photometric binaries and 10 are new candidate spectroscopic binaries.
Physical Properties of the Supernova Remnant Population in the Small Magellanic Cloud
Authors: Leahy D. A. , Filipović M. D.
Published: May 2022

The X-ray emission from a supernova remnant is a powerful diagnostic of the state of its shocked plasma. The temperature and the emission measure are related to the energy of the explosion, the age of the remnant, and the density of the surrounding medium. Here we present the results of a study of the remnant population of the Small Magellanic Cloud. Progress in X-ray observations of remnants has resulted in a sample of 20 remnants in the Small Magellanic Cloud with measured temperatures and emission measures. We apply spherically symmetric supernova remnant evolution models to this set of remnants to estimate ages, explosion energies, and circumstellar medium densities. The distribution of ages yields a remnant birth rate of ∼1/1200 yr. The energies and densities are well fit with log-normal distributions, with means of 1.6 × 1051 erg and 0.14 cm−3, and 1σ dispersions of a factor of 1.87 in energy and 3.06 in density, respectively.

Gravitational-wave detectors are starting to reveal the redshift evolution of the binary black hole (BBH) merger rate, R
BBH(z). We make predictions for R
BBH(z) as a function of black hole mass for systems originating from isolated binaries. To this end, we investigate correlations between the delay time and black hole mass by means of the suite of binary population synthesis simulations, COMPAS. We distinguish two channels: the common envelope (CE), and the stable Roche-lobe overflow (RLOF) channel, characterized by whether the system has experienced a common envelope or not. We find that the CE channel preferentially produces BHs with masses below about 30 M
⊙ and short delay times (t
delay ≲ 1 Gyr), while the stable RLOF channel primarily forms systems with BH masses above 30 M
⊙ and long delay times (t
delay ≳ 1 Gyr). We provide a new fit for the metallicity-dependent specific star formation rate density based on the Illustris TNG simulations, and use this to convert the delay time distributions into a prediction of R
BBH(z). This leads to a distinct redshift evolution of R
BBH(z) for high and low primary BH masses. We furthermore find that, at high redshift, R
BBH(z) is dominated by the CE channel, while at low redshift, it contains a large contribution (∼40%) from the stable RLOF channel. Our results predict that, for increasing redshifts, BBHs with component masses above 30 M
⊙ will become increasingly scarce relative to less massive BBH systems. Evidence of this distinct evolution of R
BBH(z) for different BH masses can be tested with future detectors.

There are currently many large-field surveys that are operational and are being planned including the powerful Vera C. Rubin Observatory Legacy Survey of Space and Time. These surveys will increase the number and diversity of transients dramatically. However, for some transients, like supernovae (SNe), we can gain more understanding by directed observations (e.g., shock breakout and γ-ray detections) than by simply increasing the sample size. For example, the initial emission from these transients can be a powerful probe of these explosions. Upcoming ground-based detectors are not ideally suited to observing the initial emission (shock emergence) of these transients. These observations require a large field-of-view X-ray mission with a UV follow-up within the first hour of shock breakout. The emission in the first 1 hr to even 1 day provides strong constraints on the stellar radius and asymmetries in the outer layers of stars, the properties of the circumstellar medium (e.g., inhomogeneities in the wind for core-collapse SNe and accreting companions in thermonuclear SNe), and the transition region between these two areas. This paper describes a simulation for the number of SNe that could be seen by a large field-of-view lobster-eye X-ray and UV observatory.

The merger of two galaxies, each hosting a supermassive black hole (SMBH) of mass 106

This would suggest no present-day evidence for a past major merger like that recently simulated, where scouring by a q ∼ 1 SMBH binary formed a stellar core with kinematic traits like those of NGC 4472. (4) Astrometric monitoring could independently check the upper limits on q from searches for continuous gravitational waves from NGC 4472.

ZTF J213056.71+442046.5 is the prototype of a small class of recently discovered compact binaries composed of a white dwarf and a hot subdwarf that fills its Roche lobe. Its orbital period of only 39 minutes is the shortest known for the objects in this class. Evidence for a high orbital inclination (i = 86°) and for the presence of an accretion disk has been inferred from a detailed modeling of its optical photometric and spectroscopic data. We report the results of an XMM-Newton observation carried out on 2021 January 7. ZTF J213056.71+442046.5 was clearly detected by the Optical Monitor, which showed a periodic variability in the UV band (200–400 nm), with a light curve similar to that seen at longer wavelengths. Despite accretion on the white dwarf at an estimated rate of the order of 10−9
M
⊙ yr−1, no X-rays were detected with the EPIC instrument, with a limit of ∼1030 erg s−1 on the 0.2–12 keV luminosity. We discuss possible explanations for the lack of a strong X-ray emission from this system.

La psychologie positive consiste à l’étude scientifique des facteurs qui mène au bien-être, soit au fonctionnement optimal d’une personne. On remarque toutefois une absence de consensus sur la définition du bien-être. Or, afin de pouvoir le favoriser, il faut pouvoir le définir. Historiquement, le bien-être a été réduit soit à un état de plaisir, soit à une quête de sens à la vie. Les théories contemporaines proposent quant à elle que le bien-être soit un phénomène multidimensionnel caractérisé par les aspects adaptatifs du fonctionnement d’une personne. Toutefois, elles ne s’entendent pas sur les aspects ou dimensions du fonctionnement devant être considérés et se concentrent plus étroitement sur le fonctionnement psychologique. La perspective du « fonctionnement optimal en société » (FOS) propose qu’une personne fonctionne de façon optimale lorsqu’elle présente un haut niveau de bien-être psychologique, social, et physique, qu’elle est performante dans son domaine d’activité principale et qu’elle contribue à la société. Les dimensions du FOS s’avèrent promues par un engagement soutenu dans diverses activités accomplies avec une passion harmonieuse, un prédicteur connu du bien-être. Les recherches réalisées à ce jour sur la passion et le FOS soutiennent cette perspective.

À la lumière des grandes tendances mondiales (l’augmentation du vieillissement des populations, l’accroissement de la longévité, la diminution des taux de natalité, par exemple), il est crucial de construire, de cultiver et d’entretenir le bien-être (BE), mais la tâche devient aussi de plus en plus complexe et exigeante. Au cours de la dernière décennie, les études menées sur des jumeaux nous ont permis de mieux comprendre dans quelle mesure les gènes et les environnements contribuent aux différences individuelles en matière de bien-être. Nos connaissances sur ces facteurs génétiques et environnementaux ne cessent de s’accroître grâce aux études sur les phénotypes liés au bien-être, aux extensions des études sur les jumeaux, aux études sur la génétique moléculaire et aux études environnementales. Ce chapitre donne un aperçu des orientations passées, présentes et futures de la recherche génétique comportementale sur le bien-être, le bonheur et les phénotypes connexes.

Les environnements reconstituants ( restorative environments ) permettent et favorisent la restauration de ressources ou de capacités qui se sont vues diminuées à la suite d’un effort adaptatif. La théorie de la restauration de l’attention, proposée par Kaplan, et la théorie de réduction du stress, proposée par Ulrich, sont les deux principales théories de psychologie de l’environnement qui sous-tendent cette approche. Pour Kaplan et Kaplan (1989), les effets reconstituants d’un environnement seraient dus à quatre facteurs : l’évasion, l’étendue, la fascination et la compatibilité. Ainsi, ces environnements présenteraient un certain potentiel thérapeutique, en contribuant à l’amélioration de la santé, du bien-être et des performances des individus. Un environnement peut devenir reconstituant par certaines de ses caractéristiques ou certaines activités qu’il permet. Les principales caractéristiques documentées dans la littérature sont l’exposition à la nature et la présence de distractions positives. Ces éléments doivent être pris en compte dans la conception et l’aménagement des espaces.

Les processus d’adaptation de l’individu face aux événements de vie sont nombreux. On constate que face à certaines situations, les individus mobilisent des ressources internes en termes de croyances, de valeurs ou de pratiques qui émanent ou s’inscrivent dans le champ de la religion et de la spiritualité. De tels concepts embrassent l’histoire de l’humanité depuis ses origines. La religion et la spiritualité, bien que très proches, restent néanmoins des notions distinctes. La spiritualité peut être définie comme la partie de notre vie intérieure qui a un rapport avec l’absolu, l’infini ou l’éternité, que ceux-ci soient conçus comme transcendants et personnels ou bien comme immanents et impersonnels. La religion, quant à elle, peut être envisagée comme un ensemble de croyances et de dogmes définissant le rapport de l’homme avec le sacré. Il s’agit également d’un ensemble de pratiques et de rites. La recherche en psychologie, et notamment la psychologie positive, se sont saisies de ces notions afin de mieux saisir leurs effets sur la santé et le bien-être des individus.

Le coping, employé pour désigner les efforts de modération et de résistance d’un individu face aux impacts psychosociaux d’une situation stressante, est un concept régulièrement rencontré en psychologie de la santé. Néanmoins d’autres modèles, ne s’opposant pas forcément au coping, sont associés au champ de l’adaptation et permettent d’illustrer des situations de confrontation à une adversité si bouleversante qu’elle fait tout voler en éclat et ne laisse que l’option d’une réinvention et d’une reconstruction. Ces modèles sont celui de la croissance posttraumatique où le sujet va dépasser cet état mental pathogène pour se transcender et grandir à partir de l’épreuve vécue, celui du changement de valeurs où le bouleversement chez le sujet va se cristalliser en une nécessité de changer ses valeurs, ses croyances, son regard sur le monde, et celui de la résilience, processus durant lequel le sujet devra à la fois attribuer du sens à l’événement, produire des efforts de coping, et engager une mobilisation ou une acquisition de ressources.

La sociologie est restée quelque peu en retrait des études sur le bonheur en comparaison d’autres disciplines, au premier rang desquelles la psychologie ou l’économie. En plus de certaines raisons trouvées dans la littérature, ce chapitre se penche sur une lecture historique de certaines trajectoires qui peuvent expliquer pourquoi la sociologie reste en retrait des études actuelles. À certaines raisons épistémologiques qui traversent les traditions nationales viennent s’ajouter des particularités géographiques et historiques. En particulier, au moment de la constitution de la sociologie française comme discipline universitaire, dans les années 1960, le travail d’exégèse s’est appuyé sur l’antisubjectivisme prôné par Durkheim au début du siècle, en opposition à Tarde et Worms, ce qui eut pour effet de délaisser les ressentis et les sentiments individuels.
