Simulasi Performa Turbin Propeller Dengan Sudut Pitch Yang Divariasikan
Authors: Pribadyo Pribadyo , H Hadiyanto , J Jamari 
Published: June 2020

Propeller turbine performance can be improved by changing the turbine design parameters. One method that was developed is to vary the blade angle on the runner's blades. Analysis of the influence of blade angle on propeller turbine performance is done through numerical simulations based on computational fluid dynamics. The simulation is done with variations of propeller turbine blade angles of 180, 230, and 280 at flow rates of 0.08 m/s to 0.5 m/s. Simulation results show turbines with 250 blade angles have the best performance compared to turbine blade angles of 230 and 280. While the turbine blade angles of 230 tend to have higher performance compared to angles of 280 even though both have peak values for the corresponding power coefficient. Keywords—Propeller turbine, runner blade, pitch angle, CFD simulation
A toponímia indígena artificial no Brasil: uma classificação dos nomes de origem tupi criados nos séculos XIX e XX
Authors: Navarro Eduardo De Almeida 
Published: June 2020

No território brasileiro encontram-se topônimos de origem indígena de mais de quinhentos anos de existência, atribuídos pelos próprios índios do passado, talvez até antes do Descobrimento do Brasil, ao lado de nomes indígenas artificiais que têm poucas décadas de existência. Tais nomes surgiram a partir da segunda metade do século XIX e sua criação tornou-se muito comum até os anos 50 do século XX. Esses topônimos artificiais são, muitas vezes, confundidos com os topônimos espontâneos de origem indígena, que são principalmente provenientes do tupi antigo e das línguas gerais dele originadas, ou seja, a língua geral meridional (ou paulista), a língua geral amazônica e o nheengatu. As razões históricas para a ocorrência de tal fenômeno foram o fortalecimento dos nacionalismos políticos no século passado, com reflexos no Brasil, o advento do Modernismo, com profundos efeitos sobre a cultura ocidental em geral e sobre a cultura brasileira, em particular.Este artigo analisa tal toponímia artificial, sua adequação geográfica e linguística e busca explicar seu surgimento.
Memória e Espaço Manauenses na crônica Margens Secas da Cidade (2013), de Milton Hatoum
Authors: Sousa Rayron Lennon Costa , Freiras Risoleta Viana 
Published: June 2020

A Amazônia Brasileira, região norte do país, especificamente, a cidade de Manaus, ambientou grande parte da produção literária de Milton Hatoum. Exemplo disso são as obras: Relato de um certo Oriente (1989), Dois Irmãos (2000), Cinzas do Norte (2005) e Um Solitário à espreita (2013), em que percebemos a cidade de Manaus como espaço construído e evocado inúmeras vezes pela tessitura memorialista do autor. Nesse sentido, objetivamos discutir a evolução do espaço citadino em Manaus a partir da relação entre as memórias construídas na infância e a revisitação dos mesmos espaços geradores na vida adulta, partindo de uma análise contrastivo-explicativa do tempo cronológico, inferindo ainda sobre o lugar da memória no processo de reconstrução da cidade. Para tanto, este artigo tem como corpus de análise a crônica Margens Secas da Cidade (2013), integrante da coletânea Um Solitário à espreita. As discussões teóricas partiram de Assmann (2008; 2011), Halbwachs (2006), Bachelard (1993) e Tuan (2012), dentre outros, nos quais ancoramos as reflexões a respeito da memória e do espaço. Intenta-se que as discussões contemplem um olhar sobre a evolução do espaço citadino manauense, entendido pelo narrador como movimento de declínio, através da relação entre o passado e o presente, a partir do retorno aos espaços de felicidade para entender os efeitos da modernidade sobre o homem e sobre a cidade. Palavras-chave: Espaço; Memória; Manaus; Milton Hatoum.
Science Education, Overconsumption, and Survival on a Finite Planet
Authors: Connet Paul 
Published: June 2020

In my view, technological progress has raced ahead of social progress. At the press of a few buttons, we can talk with people all over the world, before we have mastered the art of communicating with the person who lives next door. We are racing faster and faster from parking lot to parking lot. We struggle and strive in order to sink into a couch and watch other people live on the other side of a plastic screen. We buy more and more objects to fill the void left by not building our lives around relationships. The nuclear family has become the ideal purchasing unit. The modern cathedral is the shopping mall and the road to hell is paved with good inventions!
Perhaps the most dangerous invention we have ever come up with is a group of experts who all share the same value system, because it is difficult for anyone in that group to challenge the shared value. Indeed, the danger is in the fact that the shared value is invisible. It is not easy to question the way we see the world: our paradigms. We do not notice the lens we see through until it cracks or clouds a little.
A Symbiotic Link Between Music, Movement, and Social Emotional Learning: Mindful Learning in Early Learners
Authors: Yanko Matt , Yap Priscilla 
Published: June 2020

In the following study we investigate how young learners engage with music and movement to illustrate their understandings and connections to nature. We discover a symbiotic relationship between the performing arts, Social Emotional Learning, and Mindful Learning over the course of six months, and examine the potentials and constraints of this harmonization. Results from this study show that learning in a co-constructivist setting, which allows opportunities for reflective listening, choice, intentional focus, and feedback, supports the development of behavioural and emotional abilities, and empowers students to delve deeper into their connections with nature through composing abstract music and movement pieces.

Authors: Chetanath Neupane  , Seeram Ramakrishna  , Jeevan Jyoti Nakarmi  , Binod Adhikari  
Published: June 2020

PyMOL and UCSF Chimera are open source multifunctional molecular visualization system developed for the use in structural biology. Both of these tools are well designed with various visualization options available for the user; with the help of such options, we have observed that the iron core binds oxygen in the heme group of oxymyoglobin. Also, various molecular surfaces, internal structures as well as bond lengths between the iron core & molecular oxygen in the heme group and that to the histidine-93 of the oxymyoglobin protein have been calculated. Implementing structural analysis feature of UCSF Chimera, the distance between iron core of heme group and molecular oxygen and that between iron core and histidine 93(H93) have been estimated and found to be 1.827 Å and 2.065 Å respectively which are in good agreement (within 0.5% error) with the bond lengths calculated by x-ray diffraction method [4] .The small value of bond length between Fe and O2 suggests the higher stability of oxygen which is important for transportation, activation and storage of enzymes to support life of living organisms on the Earth. So, it provides an insight in enzymology like oxygenase. Interestingly, oxymyoglobin protein or its constituent amino acid chain may have important role in the origin of early life on the Earth.

Prospective Humaine de l'enseignement Supérieur
Authors: Nifle Roger 
Published: June 2020

La "société du savoir" est un effet miroir de "prospective au rétroviseur". Il faut d'abord comprendre la mutation pour en saisir les points d'appui et les perspectives.Le passage d'une logique de "conformation adaptative, à une logique "d'autonomisation responsable" sera dorénavant l'enjeu et la méthode. L'intégration des trois volets axiologiques, épistémologiques et praxéologiques autour du "Sens du bien commun" et de l'empowerment ou autonomisation responsable est une réponse aux questions du congrês. Pour cela il faut dépasser "l'intelligence rationnelle", pour accéder à l'intelligence symbolique ou intelligence du Sens. La mutation est une entrée dans un âge du Sens, celui des communautés de Sens et de projets, celui des mondes et réalités virtuelles. Trois axes de changement radicaux :- l'autonomisation responsable comme enjeu, capacité et méthode d'enseignement- la création de lieux virtuels d'enseignement et de formation avec les cités macropédagogiques.- une transdisciplinarité fondée sur l"˜intelligence symbolique ou intelligence du Sens.
Regard didactique sur l'explication des différences de performance des élèves marocains et québécois aux évaluations internationales
Authors: LOUBAKI Guy Norbert , Potvin Patrice , Abad Jesus Vazquez 
Published: June 2020

Cet article présente une étude en didactique des sciences qui a eu pour objectif de mieux comprendre et expliquer les différences de performance réalisées par des jeunes marocains et québécois de 15 ans dans une évaluation internationale. Notre étude s'inscrit dans une perspective de diagnostic des conceptions en sciences (Tsai et Chou, 2002, Kraus et Minstrell, 2002 ; Thijs et Van Den Berg, 1995 ; Tsai et Chou, 2002). Le cadre théorique est inspiré des travaux de Balacheff (1995) sur la caractérisation des conceptions suivant la dynamique sujet/milieu. La démarche de recherche est basée sur une approche mixte à dominance qualitative. Nos résultats attestent l'existence d'une importante influence de conceptions d'origine culturelle dans l'orientation des réponses d'élêves aux items standardisés utilisés dans certaines grandes enquêtes internationales. Ces résultats offrent donc des pistes de réflexion sur la possibilité de relativiser les explications de différence de performance entre pays de contexte culturel différent ainsi que des pistes de solution pour les minimiser. Conséquemment, notre étude soulève un questionnement de nature didactique sur la modélisation des contenus et de format d'items dits standardisés. Quels peuvent être les invariants dans l'habillage d'un item standardisé en sciences au regard des conceptions contextuellement valides qui orientent les réponses des élêves?
Mise en place d'une démarche qualité en Management des Ressources Humaines au sein de l'université marocaine
Authors: ELKACHRADI Rachid 
Published: June 2020

La réforme universitaire au Maroc a introduit des principes de l'assurance qualité dans le Systême de l'Enseignement Supérieur. A cet égard, la loi 01-00 a mis en place un dispositif qui s'articule principalement autour de l'instauration d'un systême d'accréditation des formations et la mise en place d'un systême global d'évaluation dans l'ensemble du systême. Toutefois, le Management des Ressources humaines, clef de voute de tout projet de changement, ne sont pas mises au centre de l'opérationnalisation des chantiers de réforme.
Dans notre recherche, nous nous pencherons sur les facteurs qui entravent l'opérationnalisation des principes de l'assurance qualité pour améliorer l'efficacité et l'efficience la fonction R.H. En se basant sur les résultats obtenus dans le cadre de cette étude exploratoire, nous allons proposer les déterminants capitaux pour la mise en place d'une démarche qualité en Management des Ressources Humaines au sein des universités marocaines.
The Astrobiological Copernican Weak and Strong Limits for Intelligent Life
Authors: Westby Tom , Conselice Christopher J. 
Published: June 2020

Abstract
We present a cosmic perspective on the search for life and examine the likely number of Communicating Extra-Terrestrial Intelligent (CETI) civilizations in our Galaxy by utilizing the latest astrophysical information. Our calculation involves Galactic star formation histories, metallicity distributions, and the likelihood of stars hosting Earth-like planets in their habitable zones, under specific assumptions which we describe as the Astrobiological Copernican Weak and Strong conditions. These assumptions are based on the one situation in which intelligent, communicative life is known to exist—on our own planet. This type of life has developed in a metal-rich environment and has taken roughly 5 Gyr to do so. We investigate the possible number of CETI civilizations based on different scenarios. At one extreme is the Weak Astrobiological Copernican scenario—such that a planet forms intelligent life sometime after 5 Gyr, but not earlier. The other is the Strong Astrobiological Copernican scenario in which life must form between 4.5 and 5.5 Gyr, as on Earth. In the Strong scenario (under the strictest set of assumptions), we find there should be at least

civilizations within our Galaxy: this is a lower limit, based on the assumption that the average lifetime, L, of a communicating civilization is 100 yr (since we know that our own civilization has had radio communications for this time). If spread uniformly throughout the Galaxy this would imply that the nearest CETI is at most

lt-yr away and most likely hosted by a low-mass M-dwarf star, likely far surpassing our ability to detect it for the foreseeable future, and making interstellar communication impossible. Furthermore, the likelihood that the host stars for this life are solar-type stars is extremely small and most would have to be M dwarfs, which may not be stable enough to host life over long timescales. We furthermore explore other scenarios and explain the likely number of CETI there are within the Galaxy based on variations of our assumptions.

Published: June 2020

ObjectiveTo identify the factors potentially associated with serum gamma-glutamyltransferase (GGT) elevation in patients with rheumatoid arthritis (RA).MethodsThis is a cross-sectional monocentric study including RA patients over a 12-month period. Data on liver function, RA disease activity, and hepatotoxic and cardiovascular (CV) risk factors were systematically collected. To provide a simple tool to evaluate both joint disease activity and CV risk factors, we constructed the Disease Activity Score in 28 joints (DAS28)-GGT composite index by replacing erythrocyte sedimentation rate (ESR) with GGT.ResultsAmong the 129 included patients, 32 (25%) had isolated GGT increase. GGT correlated with age, C-reactive protein (CRP) levels, and body weight and were significantly increased in patients with alcohol intake, type 2 diabetes mellitus, hypertension, dyslipidemia, and metabolic syndrome. GGT levels also gradually increased with the number of CV risk factors and correlated with the Framingham CV risk score. The composite index DAS28-GGT remained a reliable marker of RA disease activity and accurately detected patients with CV risk factors. Conversely to the DAS28 and the DAS28-CRP, the DAS28-GGT steadily increased according to the number of CV risk factors and had an increased diagnostic value compared to the DAS28 and DAS28-CRP for the presence of at least 2 CV risk factors and a Framingham CV risk score greater than 10%.ConclusionGGT may be considered as a marker of systemic inflammation and CV risk in patients with RA. Based on these findings, we herein propose an original index, the DAS28-GGT, which is able to evaluate both joint disease activity and CV risk. This index will deserve further validation in prospective cohorts.
Urbanisation et villes frontalières en Afrique de l’Ouest
Authors: Olivier J. Walther  , Dambo Lawali , Koné Moustapha 
Published: June 2020

Cet article analyse le processus d’urbanisation et le rôle démographique des villes frontalières d’Afrique de l’Ouest. Dans une première partie, l’article montre que depuis le milieu du xx e siècle, la croissance des villes frontalières est presque toujours supérieure à celle des autres villes de la région. Cette croissance rapide est particulièrement visible à moins de 50 km des frontières, où sont localisés les marchés les plus dynamiques. Bien que la région ait connu des taux de croissance moyens spectaculaires, les villes d’une même région ou d’un même pays croissent à des rythmes très différents. Ces disparités indiquent que seule une partie des villes est réellement localisée sur des axes stratégiques ou au centre de bassins de production leur permettant de bénéficier des avantages frontaliers. L’analyse confirme que la taille des villes augmente avec la distance aux frontières, passant de 37 670 habitants à 20 km à plus de 55 000 habitants à 100 km, tandis que la moyenne ouest-africaine est de plus de 73 000 habitants. Elle montre également que la densité des villes frontalières est supérieure à la moyenne des centres urbains de la région et décroît avec la distance aux frontières. Elle varie de 7 400 habitants au kilomètre carré en moyenne à 20 km à 6 800 habitants à 100 km, ce qui témoigne de la spécificité démographique des centres urbains frontaliers. La croissance rapide des villes ouest-africaine et leur étalement devraient encourager les décideurs politiques à appuyer le développement urbain et maximiser les interactions intra-urbaines s’ils désirent profiter au mieux des économies d’agglomération.
