Authors: ERTÜRK Ramazan , SEZGİN NARTGÜN Şenay 
Published: December 2019

This study aimed to identify the relationship between teachers' distributed leadership and perceptions of schools as learning organizations. This study used correlational survey model and made use of correlations to determine the relationship between the two variables. Study population consisted of 600 teachers employed at secondary schools in the central district of Bolu in 2018-2019 academic year. The study was carried out on the population and therefore no sampling was required. Of the 600 scales distributed, 268 were returned and evaluated. The measurement tool used in the research consists of three parts. First part of the scale included demographic characteristics of teachers. The second part included the Distributed Leadership Scale and the third part consisted of the Learning School Scale. Some of the results of the research are as follows: Teachers have high perceptions of learning school and sub-dimensions such as team learning, mental models, shared vision, personal domination and shared leadership. Male and female teachers are similar in learning schools and sub-dimensions of learning in teams, mental models, shared vision and shared leadership perceptions. According to the results of the research, female teachers 'perceptions of personal dominance dimension are higher than male teachers' perceptions. Teachers with different types of in-service participation and project numbers have similar characteristics to the learning school, learning as a team, mental models, shared vision and personal dominance sub-dimensions and shared leadership perceptions. The teachers' perceptions of teachers in schools whose schools have different number of teachers show different characteristics in other dimensions and shared leadership perceptions except for personal dominance dimension.
Efficient CORDIC Iteration Design of LiDAR Sensors’ Point-Cloud Map Reconstruction Technology
Authors: Fan Yu-Cheng , Liu Yi-Cheng , Chu Chiao-An 
Published: December 2019

In this paper, we propose an efficient COordinate Rotation DIgital Computer (CORDIC) iteration circuit design for Light Detection and Ranging (LiDAR) sensors. A novel CORDIC architecture that achieves the goal of pre-selecting angles and reduces the number of iterations is presented for LiDAR sensors. The value of the trigonometric functions can be found in seven rotations regardless of the number of input N digits. The number of iterations are reduced by more than half. The experimental results show the similarity value to be all 1 and prove that the LiDAR decoded packet results are exactly the same as the ground truth. The total chip area is 1.93 mm × 1.93 mm and the core area is 1.32 mm × 1.32 mm, separately. The number of logic gates is 129,688. The designed chip only takes 0.012 ms and 0.912 ms to decode a packet and a 3D frame of LiDAR sensors, respectively. The throughput of the chip is 8.2105 × 10 8 bits/sec. The average power consumption is 237.34 mW at a maximum operating frequency of 100 MHz. This design can not only reduce the number of iterations and the computing time but also reduce the chip area. This paper provides an efficient CORDIC iteration design and solution for LiDAR sensors to reconstruct the point-cloud map for autonomous vehicles.
Effect of increased gravity on calcitic mineralization of test of foraminifera (protozoa)
Authors: Very Jean-Michel , Le Campion Joël 
Published: December 2019

Deux espèces de Foraminifères ont été décalcifiées à l'E.D.T.A. pour permettre la reminéralisation du test après remplacement du chélateur par de l'eau de mer. Cette minéralisation a lieu sous des conditions normales d'élevage pour le groupe témoin, et sous une accélération de 1,6 G pour le groupe expérimental (accélération résultante de 1,9 G). La distribution des atomes de Ca et de Mg est analysée à l'aide de la microsonde à rayons X. Les distances interréticulaires d ainsi que les largeurs des pics de diffraction sont mesurées par diffractométrie X. L'effet de l'augmentation de la gravité se traduit différemment chez les deux espèces considérées : absence de variation du rapport de concentration Mg/Ca, absence de variation des distances interréticulaires d et accroissement des valeurs des pics de diffraction chez l'une, diminution du rapport Mg/Ca, augmentation des valeurs de d et diminution des largeurs des pics chez l'autre. Une action au niveau de la membrane cellulaire est proposée.
Approche expérimentale et naturelle de la déformation des roches par dissolution˗cristallisation, avec transfert de matière
Authors: Gratier Jean-Pierre 
Published: December 2019

Divers dispositifs (déformations expérimentales, analyses sur échantillons déformés naturellement) sont décrits, qui permettent de tester des modèles de déformation des roches par dissolution˗cristallisation, avec transfert, soit par diffusion dans un fluide fixe, soit par déplacement du fluide. L'observation du changement de forme d'inclusions fluides, sous pression dans des cristaux chauffés sous un microscope permet d'établir des relations entre vitesse de déformation (ε) et divers paramètres : forme des cavités et pression interne (P). La relation ε = ƒ(P)exp[n] avec des valeurs de n autour de 3-3,5 montre l'importance de la courbure d'une surface solide˗fluide dans sa « déformation » sous pression par transfert de matière.
Dissolution expérimentale d'un rhomboèdre de calcite soumis à une contrainte. Experimental deformation, dissolution of calcite
Authors: Girou André , Esclamadon Jacqueline , Humbert Louis , Jacquin Christian , Poulet Michel , Roques Henri 
Published: December 2019

Le but de l'étude est de mettre en évidence expérimentalement l'influence des contraintes mécaniques sur la dissolution d'un cristal de calcite. Les conditions expérimentales sont les suivantes : les rhomboèdres de calcite sont soumis à une contrainte parallèle à l'axe A3 (0 à 2 400 bars). Le réacteur est alimenté en eau permutée. Le débit de circulation est fixé à 5 cm³/h. La température de travail est maintenue constante à 25 °C. On constate que la pression appliquée sur le cristal augmente la vitesse globale de dissolution. Les figures de dissolution sont localisées dans la zone médiane du cristal (zone de cisaillement). Les courbes de dissolution obtenues lors des essais en compression ou en décompression sont comparables. La contrainte agirait essentiellement par augmentation de la surface de contact entre calcite et solution. Son effet sur la solubilité thermodynamique serait négligeable.
Um estudo comparativo entre os metaplasmos presentes na Graphic Novel Pavor Espaciar, de Gustavo Duarte (2013), com base em Amaral (1920) e ALiB (2014)
Authors: Silva Marly Custódio da 
Published: December 2019

A língua enquanto instituição coletiva e viva está em constante transformação. Isso pode ser percebido por quaisquer pessoas falantes de um idioma, ou seja, as variações linguísticas não são captadas apenas pelos estudiosos da Geolinguística, Dialetologia e Sociolinguística. A estes compete o estudo científico das variantes de uma língua. O primeiro trabalho a tentar mapear o falar considerado como caipira, da pronúncia retroflexa de /r/, dentre outras, é de Amaral (1920/2 ed. 1953). De lá para cá, vários trabalhos e pesquisas culminaram com a publicação do ALiB (Atlas Linguístico do Brasil), em 2014. Dessa forma, estabelecemos paralelo entre a Graphic Novel Pavor Espaciar, de Gustavo Duarte, com resultados de Amaral e do ALiB. Para tanto, o objetivo é a análise da expressão do dialeto caipira e expor por meio da diacronia os traços da variação linguística no Brasil. As reflexões a respeito da variação linguística são sustentadas na Sociolinguística, e o preconceito linguístico abordado implicitamente por Calvet (2002). A metodologia transcorrerá com as análises diacrônicas dos quadrinhos da Graphic Novel citada identificando os metaplasmos, tendo como base Coutinho (1976) e Silva (2010), bem como as observações de Faraco (2006) em relação à percepção de mudança.

Authors: Lopes Andréia Caroline , Botassini Jacqueline Ortelan Maia 
Published: December 2019

O presente trabalho, baseado na metodologia da Sociolinguística Variacionista, examinou a variação da colocação pronominal na língua falada de norte-paranaenses. Para a análise, observaram-se, como possíveis condicionadores do fenômeno linguístico em estudo, os fatores extralinguísticos sexo, faixa etária e grau de escolaridade. O corpus da pesquisa constitui-se de oito entrevistas de informantes norte-paranaenses pertencentes ao banco de dados de entrevistas gravadas e transcritas por Botassini (2013) para a realização de sua tese. Após a análise, verificou-se que os fatores extralinguísticos grau de escolaridade e sexo foram, respectivamente, o mais determinante para o uso do clítico na fala e o que apresentou mais casos de colocação pronominal de acordo com as prescrições gramaticais.

INVESTIGATION OF THE GLOBAL PROBLEMS IMPACT ON OCCUPATIONAL SAFETY AND HEALTH IN UKRAINE
Authors: Kruzhilko O. , Lysyuk M. 
Published: December 2019

The aim of this work is to study the impact of global problems on labour protection in Ukraine to determine ways to improve labour protection measures that are traditionally used. To identify the impact of global problems on labour protection in Ukraine, a brief conceptual analysis of approaches to the labour protection management was carried out, both in Ukraine and internationally. The evaluative criterion for the hazards impacts significance was the injuries and morbidity indicators values – the frequency and severity and the risk levels of the negative consequences onset from these effects, dependent on them. It is established that the global problems in the field of OSH management in Ukraine and other developing countries are similar. To apply the program-oriented principle of planning the priority of measures to eliminate or reduce hazards, it is proposed to use their typification. The proposed hazard typification is based on legislative and regulatory documents in force in Ukraine, but can be adapted for other countries. The practical value of the study lies in the fact that the main hazards determining occupational injuries and occupational morbidity in Ukraine are identified and systematized. The main ways of improving the labour protection state are highlighted, among which there is a development of risk factors assessment scale for their quantitative assessment; development and implementation of modern information systems for timely accounting and analysis of identified hazards. The originality of the approach to OSH management is the analysis of the probl ems of injuries and morbidity at work as a general (global) problem requiring a unified approach to its solution, but with mandatory consideration of the subjective characteristics of its origin.

Abstract
We present ALMA observations of the [C ii] 158 μm fine structure line and dust continuum emission from two quasars, SDSS J104433.04−012502.2 and SDSS J012958.51−003539.7, at z = 5.78. The ALMA observations at 0.″2 resolution map the dust and gas on kiloparsec scales. The spatially resolved emission shows a similar trend of decreasing [C ii]–far-infrared (FIR) ratios with increasing FIR surface brightnesses as was found in the infrared luminous galaxies with intense star formation. We confirm the velocity gradients of [C ii] emission found previously in SDSS J0129−0035. No clear evidence of order motion is detected in SDSS J1044−0125. The velocity maps and position–velocity diagrams also suggest turbulent gas clumps in both objects. We tentatively detect a [C ii] peak offset 4.9 kpc to the east of SDSS J1044−0125. This may be associated with an infalling companion, or node of gas outflow. All these results suggest significant dynamical evolution of the interstellar medium in the nuclear region of these young quasar-starburst systems. We fit the velocity map of the [C ii] emission from SDSS J0129−0035 with a rotating disk model. The result suggests a face-on system with an inclination angle of 16° ± 20° and constrains the lower limit of the host galaxy dynamical mass to be 2.6 × 1010

Gravitational Waves from the Inspiral of Supermassive Black Holes in Galactic-scale Simulations

Published: December 2019

Abstract
We study the orbital evolution and gravitational wave (GW) emission of supermassive black hole (SMBH) binaries formed in gas-free mergers of massive early-type galaxies using the hybrid tree-regularized N-body code Ketju. The evolution of the SMBHs and the surrounding galaxies is followed self-consistently from the large-scale merger down to the final few orbits before the black holes coalesce. Post-Newtonian corrections are included up to PN3.5 level for the binary dynamics, and the GW calculations include the corresponding corrections up to PN1.0-level. We analyze the significance of the stellar environment on the evolution of the binary and the emitted GW signal during the final GW emission dominated phase of the binary hardening and inspiral. Our simulations are compared to semi-analytic models that have often been used for making predictions for the stochastic GW background emitted by SMBHs. We find that the commonly used semi-analytic parameter values produce large differences in merger timescales and eccentricity evolution, but result in only

differences in the GW spectrum emitted by a single binary at frequencies

, which are accessible by current pulsar timing arrays. These differences are in part caused by the strong effects of the SMBH binaries on the surrounding stellar population, which are not included in the semi-analytic models.
Effets du stress salin sur la germination des graines de Jatropha curcas L.
Authors: Faye Elhadji , Touré Mamoudou Abdoul , Diouf Yandé Koune 
Published: December 2019

La salinisation des terres au Sénégal est une préoccupation nationale. Elle affecte une bonne partie des populations de la zone du bassin arachidier et rend précaire la production agricole. La recherche d’espèces performantes en milieu salé est une priorité. Pour y contribuer, cette étude vise à tester en milieu réel et contrôlé le comportement en germination des graines de Jatropha curcas L. Les facteurs étudiés sont le milieu environnemental, le stress salin et le calibre des graines. Les résultats obtenus montrent que le substrat, le terreau et le coton sont les meilleurs supports de germination (35,64±9,72 %). Le maximum de germination des graines est obtenu entre les 6e et 10e jours (62,84±8,41 %). En milieu contrôlé, les graines de J. curcas sont capables de germer à une concentration de 11,68 g.l-1 de NaCl (T3). En milieu réel, le taux de germination est très bas en tanne herbeuse plus salée (1±7,61 %) contre 23±7,61 % en tanne arbustive moins salée. Les graines de petite taille germent mieux que les moyennes et grosses graines (p = 0,017).
Patrimoines de papier. Superposition des aires naturelles protégées et développement territorial dans l’île de Lanzarote (Canaries, Espagne)
Authors: Babou Igor 
Published: December 2019

Quels sont les effets, sociaux et environnementaux, de la multiplication sur un même territoire de dispositifs de protection de la nature ? En s’appuyant sur l’étude ethnographique d’un territoire insulaire fragile (l’île de Lanzarote, Archipel des Canaries, Espagne), de la diversité de ses aires naturelles protégées, de ses inscriptions par l’Unesco (réserve de biosphère et géoparc) et des cadres réglementaires locaux, cet article montre la faible emprise sur le territoire des dispositifs de protection de l’environnement dans un contexte caractérisé par la corruption politique et les forts enjeux économiques du tourisme. La superposition de labels patrimoniaux, loin de conduire à des redondances fonctionnelles, ou à des synergies allant dans le sens d’un développement soutenable, produit dans ce contexte des effets de clôture et de concurrence entre les structures patrimoniales. Une logique de « marque » prend parfois le pas sur des enjeux écologiques pourtant bien ancrés dans l’histoire de l’île de Lanzarote, mais qui s’érodent faute d’être soutenus.
