Published: June 2020

Introdução: A agilidade é fundamental para o judô, uma luta que demanda força e potência e utiliza mudanças bruscas de direção. Pouco se investigou, no Brasil, a respeito da qualidade física agilidade em crianças escolares pré-puberes.Objetivo: Comparar o nível de agilidade entre crianças praticantes e não-praticantes de judô de uma escola pública.Métodos: Pesquisa descritiva de corte transversal comparativa, da qual participaram 77 crianças de ambos os sexos: 47 praticantes de judô e 30 não praticantes. Teste t de Student para amostras independentes foi aplicado para a comparação entre os grupos.Resultados: Os praticantes regulares de judô exibiram maiores níveis de agilidade (10,98±0,79 segundos) do que os não praticantes de judô (13,48±0,74 segundos) e a diferença foi significativa (p=0,0001).Conclusão: Crianças que praticam judô apresentaram níveis maiores de agilidade do que as participantes de iniciação esportiva em outras modalidades, sugerindo que o treinamento de judô pode favorecer o desenvolvimento dessa capacidade física mais do que as demais modalidades. Outros estudos de intervenção devem ser conduzidos para esclarecer essa associação.

Little has been investigated in Brazil regarding physical quality agility in prepubescent school children.Objective: To compare the level of agility between practicing and non-practicing children of judo in a public school.Methods: A descriptive comparative cross-sectional study was conducted in which 77 children of both sexes participated: 47 judo practitioners and 30 non-practitioners. Student's t-test for independent samples was applied for comparison between groups.Results: Regular judo practitioners exhibited higher levels of agility (10.98 ± 0.79 seconds) than non-judo practitioners (13.48 ± 0.74 seconds) and the difference was significant (p = 0.0001).Conclusion: Children who practice judo showed more agility than participants of sports initiation in other modalities suggesting that judo training may favor the development of this physical capacity more than the other modalities. Further intervention studies should be conducted to clarify this association.

Published: June 2020

Introdução: A periodização no treinamento de força é necessária para obtenção de maiores ganhos das diferentes manifestações da força à medida que o treinamento avança.
Objetivo: Comparar dois diferentes modelos de periodização sobre a força máxima e potência utilizando por um período de 24 semanas.
Métodos: Estudo experimental, com amostra por conveniência, do qual participaram 12 jovens adultos (20-45 anos), de ambos os sexos. Os participantes foram aleatoriamente alocados nos dois tipos de intervenção: periodização ondulatória semanal (POS) e periodização ondulatória diária (POD). A intervenção teve a duração de 24 semanas.
Resultados: Tanto POD como POS apresentaram melhorias para a força, porém na POD os ganhos foram observados a partir da semana 8 (p = 0,003) e POS a partir da semana 16 (p = 0,004) sem diferenças significativas para os testes de potência. Quanto às diferenças intergrupos, foi observado um tamanho do efeito médio (d = 0,512) na semana 16 para a POD quando comparada à POS no leg press 45º. Para potência, foi observado tamanho do efeito médio no SJT no período pós (d = 0,549) para a POS se comparada à POD.
Conclusão: Conclui-se que, comparando-se os métodos POS e POD para otimizar ganhos de força, a POD é mais eficiente, porém, se o objetivo for melhorar o desempenho da potência, a POS pode ser a melhor estratégia.

La representación de la mujer en la música es un objeto de investigación poco desarrollado académicamente y mucho menos en estilos musicales contemporáneos y populares como es el caso de la música urbana. El presente texto propone el análisis los estereotipos de mujer como personaje en canciones de reggaetón de éxito internacional interpretadas por hombres. Para este fin se ha empleado primordialmente fichas de análisis de contenido de los clips más vistos en YouTube durante el año 2018. El diseño de la ficha se alimenta de otras investigaciones realizas previamente por autores expertos en el tema, para finalmente sintetizar la información en tres bloques: los dos primeros, codificados para obtener resultados cuantitativos y el tercero, para recogida de datos de carácter cualitativo.
THE ISSUE OF THE RUSSIAN TRADITIONS lawmaking In the XVII century
Authors: Ельчанинова Ольга Юрьевна 
Published: June 2020

Вопросы познания правотворческой традиции XVII в., ее диалектической связи с факторами общественного развития нуждаются в дальнейшем изучении в отечественной правовой доктрине. Исследование эволюции отечественного правотворческого процесса предопределило обращение автора статьи к изучению его субъектов, порядка и результатов. Автором показано, что появление большого массива правового материала вызывало потребность в совершенствовании способов и приемов создания правовых норм, навыков их формулирования и толкования. Результатом систематизации законодательства стало Соборное уложение, которое консолидировало огромный массив актов, изданных различными субъектами правотворчества, регламентирующих различные сферы общественных отношений. Сделан вывод относительно того, что именно в XVII в. стало складываться паритетное соотношение между обычным правом и законом. Этот период можно считать началом нового этапа эволюции отечественного правотворческого процесса. В рамках исследования применялся диалектический подход, метод ретроспективного анализа, метод систематизации и др.
In the domestic legal doctrine, issues of knowledge of the law-making tradition of the 17th century, its dialectical connection with factors of social development need further study. A study of the evolution of the domestic law-making process predetermined the appeal of the author of the article to the study of its subjects, order and results. The author shows that the emergence of a large array of legal material caused the need to improve the methods and techniques of creating legal norms, the skills of their formulation and interpretation. The result of the systematization of legislation was the Council Code, which consolidated a huge array of acts issued by various subjects of lawmaking that govern various spheres of public relations. The conclusion is made about what exactly in the XVII century. a parity relationship has developed between customary law and law. This period can be considered the beginning of a new stage in the evolution of the domestic law-making process. The study used the dialectic approach, the retrospective analysis method, the systematization method, etc.
Simultaneous Optical Transmission Spectroscopy of a Terrestrial, Habitable-zone Exoplanet with Two Ground-based Multiobject Spectrographs

Published: June 2020

Abstract
Investigating the atmospheres of rocky exoplanets is key to performing comparative planetology between these worlds and the terrestrial planets that reside in the inner solar system. Terrestrial exoplanet atmospheres exhibit weak signals, and attempting to detect them pushes at the boundaries of what is possible for current instrumentation. We focus on the habitable-zone terrestrial exoplanet LHS 1140b. Given its 25-day orbital period and 2 hr transit duration, capturing transits of LHS 1140b is challenging. We observed two transits of this object, approximately 1 yr apart, which yielded four data sets thanks to our simultaneous use of the IMACS and LDSS3C multiobject spectrographs mounted on the twin Magellan telescopes at Las Campanas Observatory. We present a jointly fit white light curve, as well as jointly fit 20 nm wavelength-binned light curves from which we construct a transmission spectrum. Binning the joint white light-curve residuals to 3-minute time bins gives an rms of 145 ppm; binning down to 10-minute time bins gives an rms of 77 ppm. Our median uncertainty in

in the 20 nm wavelength bins is 260 ppm, and we achieve an average precision of 1.3× the photon noise when fitting the wavelength-binned light curves with a Gaussian process regression. Our precision on

is a factor of four larger than the feature amplitudes of a clear, hydrogen-dominated atmosphere, meaning that we are not able to test realistic models of LHS 1140b’s atmosphere. The techniques and caveats presented here are applicable to the growing sample of terrestrial worlds in the Transiting Exoplanet Survey Satellite era, as well as to the upcoming generation of ground-based giant segmented mirror telescopes.
Constraints on the Distances and Timescales of Solid Migration in the Early Solar System from Meteorite Magnetism

Published: June 2020

Abstract
The migrations of solid objects throughout the solar system are thought to have played key roles in disk evolution and planet formation. However, our understanding of these migrations is limited by a lack of quantitative constraints on their timings and distances recovered from laboratory measurements of meteorites. The protoplanetary disk supported a magnetic field that decreased in intensity with heliocentric distance. As such, the formation distances of the parent asteroids of ancient meteorites can potentially be constrained by paleointensity measurements of these samples. Here, we find that the WIS 91600 ungrouped C2 chondrite experienced an ancient field intensity of 4.4 ± 2.8 μT. Combined with the thermal history of this meteorite, magnetohydrodynamical models suggest the disk field reached 4.4 μT at ∼9.8 au, indicating that the WIS 91600 parent body formed in the distal solar system. Because WIS 91600 likely came to Earth from the asteroid belt, our recovered formation distance argues that this body previously traveled from ∼10 au to 2–3 au, supporting the migration of asteroid-sized bodies throughout the solar system. WIS 91600 also contains chondrules, calcium-aluminum-rich inclusions and amoeboid olivine aggregates, indicating that some primitive millimeter-sized solids that formed in the innermost solar system migrated outward to ∼10 au within ∼3–4 Myr of solar system formation. Moreover, the oxygen isotopic compositions of proposed distal meteorites (WIS 91600, Tagish Lake and CI chondrites) argue that the CM, CO, and CR chondrites contain micrometer-scale dust and ice that originated in the distal solar system.
A Comparison of X-Ray Photon Indices among the Narrow- and Broad-line Seyfert 1 Galaxies
Authors: Ojha Vineet , Chand Hum , Dewangan Gulab Chand , Rakshit Suvendu 
Published: June 2020

Abstract
We present a detailed comparative systematic study using a sample of 221 narrow-line Seyfert 1 (NLSy1) galaxies in comparison to a redshift-matched sample of 154 broad-line Seyfert 1 (BLSy1) galaxies based on their observations using ROSAT and/or XMM-Newton in soft X-ray band (0.1–2.0 keV). A homogeneous analysis is carried out to estimate their soft X-ray photon indices (

) and its correlations with other parameters of nuclear activities such as Eddington ratios (R
Edd), bolometric luminosities (L
bol), black hole masses (M
BH), and the widths of the broad component of Hβ lines (FWHM(Hβ)). In our analysis, we found clear evidence of the difference in the

and R
Edd distributions among NLSy1 and BLSy1 galaxies, with steeper

and higher R
Edd for the former. Such a difference also exists in the spectral index distribution in hard X-ray (

), based on the analysis of 53 NLSy1 and 46 BLSy1 galaxies in the 2–10 keV energy band. The difference in R
Edd distributions does exist even after applying the average correction for the difference in the inclination angle of NLSy1 and BLSy1 galaxies. We also estimated R
Edd, based on SED fitting of 34 NLSy1 and 30 BLSy1 galaxies over the 0.3–10 keV energy band, and found that results are still consistent with R
Edd estimates based on the optical bolometric luminosity. Our analysis suggests that the higher R
Edd in NLSy1 is responsible for its steeper X-ray spectral slope compared to the BLSy1, consistent with the disk-corona model as proposed for the luminous AGNs.
Non-detection of M60-UCD1 in Quasi-simultaneous X-Ray and Radio Observations
Authors: Lena Davide , Rogantini Daniele , Miller-Jones James C. A. , Jonker Peter G. 
Published: June 2020

Abstract
Simultaneous detection in X-rays and radio, following the proportionality implied by the “fundamental plane of black hole activity,” can indicate the presence of an accreting black hole (BH), allowing a rough estimate of its mass. We used the XMM-Newton satellite and the Karl G. Jansky Very Large Array to perform quasi-simultaneous observations (within 24 hr) of the ultra-compact dwarf galaxy M60-UCD1, where the presence of a supermassive BH was inferred from stellar dynamics. The galaxy was not detected in either the X-ray or the radio band. We used the fundamental plane of BH activity to set constraints on the mass of any BH that might reside in its nucleus.
Inclusion, bien-être et APA thérapeutique

À l’heure où les cliniques psychiatriques ne se désemplissent pas, le rôle des gem est primordial, pour « l’avenir du handicap psychique » notamment, mais également pour les personnes avec des troubles du spectre autistique ou vieillissantes. En effet, les groupes d’entraide mutuelle permettent d’apporter un autre regard : vierge et non médical. Certes, la distinction entre soin et accompagnement n’est pas toujours clarifiée correctement auprès de tous, ce qui ne donne pas encore une entière légitimité aux bienfaits des gem . Il est vrai que pour le moment il n’y a pas assez de recul sur ces pratiques. Toutefois, Patrick Gohet, délégué interministériel aux Personnes handicapées, déclarait en 2004 dans une interview à Sport adapté magazine : « Il est indispensable que, dans les structures de vie et de travail où il y a des activités d’accompagnement, les activités physiques et sportives trouvent toute leur place. » C’est pourquoi l’association sportive Actiphypsy vise un accompagnement exigeant des usagers des gem à partir d’une pratique raisonnée des activités physiques adaptées ( apa ) et accompagnés par des professionnels apa .
Les adjectifs tough et le marquage de l’infinitif en néerlandais
Authors: Lagae Véronique , Van Peteghem Marleen 
Published: June 2020

En néerlandais, les adjectifs du type ‹difficile› ou ‹facile› entrent dans deux constructions qui se distinguent par la présence ou l’absence du complémenteur OM. L’objectif de cette étude est de montrer que ces deux constructions correspondent à deux analyses de la construction Tough proposées pour l’anglais et qu’elles donnent lieu à deux délimitations différentes de la classe des adjectifs tough . La construction appelée easy-to-please (avec OM) peut s’analyser comme une relative réduite, donc comme un ‹mouvement non A› alors que l’infinitif modal (sans OM) a les propriétés d’une structure à montée, donc de ‹mouvement A›. Nous montrons également que les adjectifs tough au sens strict, signifiant ‹difficile›, ‹facile›, ont une préférence nette pour la construction à infinitif modal, qui est donc la vraie construction Tough du néerlandais.
Circuits courts agro-alimentaires et clivages politiques : le cas des produits palmipèdes landais
Authors: Smith Andy 
Published: June 2020

Depuis 15 ans, la recherche a produit des analyses fines des relations marchandes qu’implique l’agriculture en circuit court. Toutefois, le paradigme relationnel qui l’a dominée tend fortement à minimiser les conflits politiques qui marquent les industries agricoles concernées en les réduisant à des « jeux » qui ne sont que partiellement stabilisés. En s’appuyant sur une enquête portant sur l’industrie des produits palmipèdes, et guidé par l’institutionnalisme constructiviste, cet article restitue plus frontalement l’antagonisme structurel qui s’est développé autour des « circuits courts » dans les Landes, les deux objectifs socio-économiques contrastants qui leur sont attribués, et l’impact de ce clivage politique sur la régulation de la biosécurité, des labels et de l’installation des nouveaux entrants. Le texte dans son ensemble montre notamment que si les grippes aviaires de 2015-2016 semblaient initialement « rebattre les cartes » en faveur de la production en circuit court, dans cette industrie les institutions et les relations de pouvoir de longue durée ont rapidement contribué à restaurer une division du travail entre la production, la transformation et la commercialisation.
Combination of Hiding and Encryption for Data Security

Published: June 2020

<pre>One of the techniques used in information security is the concealment technique, where the information to be hidden within another information medium to be saved in the process of messaging between two sides without detection. In this paper, an algorithm was proposed to conceal and encrypt data using several means.in order to ensure its preservation from detection and hackers. Wavelet transformer was used to change the shape of a wave of information (one and two-dimensional data) and its different mathematical formulas. Two sets of data were used, the first group used in a hidden process. The second group was considered as a means of both embedding and encryption. The data in the second group is reduced to the extent of sufficient for the modulation process, by extracting its high-value properties and then removing them from the mother's information wave. The process of encrypting of the two sets of data comes together using an exponential function. The result is undetectable information signals. Algorithms were built to hide and encrypt one and two-dimensional data. High-security signals and images were obtained. Decryption algorithms were built to return encrypted data to their original forms, and getting the replica data.</pre><p> </p>
P2Y6 Deficiency Enhances Dendritic Cell–Mediated Th1/Th17 Differentiation and Aggravates Experimental Autoimmune Encephalomyelitis
Authors: Li Zhenlong , He Cong , Zhang Jiang , Zhang Hongmei , Wei Huan , Wu Shijia , Jiang Wenzheng 
Published: June 2020

Abstract
Dendritic cells (DCs) are essential APCs and play a crucial role in initiating and regulating the adaptive immune response. In this study, we have reported that P2Y6, a member of G protein–coupled receptors, inhibits the maturation and activation of DCs via suppressing the activation of the transcription factor NF-κB. Furthermore, loss of P2Y6 does not impact T cells homeostasis in the steady-state. However, in vitro studies show that P2Y6 signaling inhibits the production of IL-12 and IL-23 and the polarization of Th1 and Th17 subsets mediated by DCs. In addition, we find that mice lacking P2Y6 develop more severe experimental autoimmune encephalomyelitis compared with wild-type mice. Our results indicate that P2Y6 functions as a pivotal regulator on DC maturation, and the loss of P2Y6 results in the aggravated experimental autoimmune encephalomyelitis, which suggests that P2Y6 may play a pivotal role in the pathogenesis of autoimmune diseases.
Increase of resting muscle stiffness, a less considered component of age-related skeletal muscle impairment
Authors: Marcucci Lorenzo , Reggiani Carlo 
Published: June 2020

Elderly people perform more slowly movements of everyday life as rising from a chair, walking, and climbing stairs. This is in the first place due to the loss of muscle contractile force which is even more pronounced than the loss of muscle mass. In addition, a secondary, but not negligible, component is the rigidity or increased stiffness which requires greater effort to produce the same movement and limits the range of motion of the joints. In this short review, we discuss the possible determinants of the limitations of joint mobility in healthy elderly, starting with the age-dependent alterations of the articular structure and focusing on the increased stiffness of the skeletal muscles. Thereafter, the possible mechanisms of the increased stiffness of the muscle-tendon complex are considered, among them changes in the muscle fibers, alterations of the connective components (extracellular matrix or ECM, aponeurosis, fascia and tendon) and remodeling of the neural pattern of muscle activation with increased of antagonist co-activation.

Abstract
Background: Optimal management of metastatic nasopharyngeal carcinoma (NPC) at presentation is debatable. The aim of this study was to investigate the treatment outcome of patients with metastatic NPC treated with concurrent chemoradiation or with radiation alone and to analyze the factors that correlate with the outcome. Methods: This was a retrospective study of patients with metastatic NPC treated in Cancer Institute, Chennai, from 1996 to 2015 with either chemoradiation or only radiation. Factors including age, sex, stage, treatment type, and type of metastasis were correlated with the outcome. Statistical analysis was done using SPSS version 20, and survival was estimated by Kaplan–Meier’s curve. Results: A total of 515 patients with NPC were treated during this period, and among them, 74 patients (14%) had metastasis at the time of presentation. The median follow-up was 14 months; the median progression-free survival and overall survival (OS) were 11 months and 19 months, respectively. About 72% (n = 53) were treated with chemoradiation and the rest 28% (n = 21) were treated with radiation alone. The 3-year OS was better in patients who received chemoradiation (39%) as compared to those who received only radiation (23.8%). Patients with the bone-only site of metastasis had better survival. Among them patients with oligometastatic bone disease (1–3 sites) had a better 3-year OS (51%) as compared to multiple bone metastasis (>3) 15.8%. Conclusion: Chemoradiation can be an option to treat metastatic NPC. Patients with oligometastatic bone disease had better survival.
