Raman microprobe analysis of gaseous inclusion in diagenetically recrystallized calcites
Authors: Guilhaumou Nicole , Velde Bruce , Bény Claire 
Published: November 2018

Les inclusions fluides ont été étudiées par microthermométrie et microsonde Raman dans des recristallisations calcitiques de sédiments carbonatés prélevés par forage à une profondeur de 6,5 km dans le Smackover (Jurassique) à Perry County (Mississippi).
On a pu mettre en évidence en particulier les associations CH4-H2S -carbone, CH4-CO2-H2S -carbone et CH4-CO2-H2S-H2O -carbone, dont le comportement à basse température est caractéristique du système CH4-H2S.
La comparaison des spectres Raman de la phase solide avec des travaux antérieurs sur une série de charbons montre qu'il s'agit d'un composé graphitique mal organisé, comparable au produit habituel de la maturation du kerogen lors de la métagenèse.
Les fluides aqueux sont constitués par des saumures riches en ions Ca. Les températures d'homogénéisation des inclusions précoces et des inclusions tardives indiquent, après correction de pression, des valeurs de piégeage identiques et comparables à celles mesurées actuellement au fond du puits.
Compte tenu de l'importance des décrépitations des inclusions précoces, on peut supposer qu'il y a eu modification de leur densité et réajustement selon les conditions actuelles de température et de pression.
Ces résultats suggérent soit l'évolution in situ des hydrocarbures piégés sous forme liquide ou gazeuse vers une association composée d'un résidu graphitique et d'un gaz riche en H2S ne contenant pas d'hydrocarbures plus lourds que le méthane, soit le piégeage des gaz CH4-H2S-CO2 et leur évolution vers leurs conditions de stabilité thermique maximum.
Analyse des phases fluides associées à la genèse des amas sulfurés et des filons Au-Ag de la province de Taxco-Guanajuato (Mexique)
Authors: Charoy Bernard , Gonzalez-Partida Eduardo 
Published: November 2018

Two principal types of sulphide occurrences have been recognized in the Taxco-Guanajuato province :
1 ) Exhalative-like massive sulphide deposits enclosed in the metamorphic Tizapa sequence and,
2) Quartz veins with sulphide concentrations spatially related with intrusive monzogranite stocks.
The characteristics of the hydrothermal solutions genetically responsible for the mineralizations are determined using fluid inclusion studies. 3 different types of solutions are identified :
— Hypersaline brines (bulk salinity up to 67 wt %) close to halite saturation at elevated temperature (⋍ 500 °C) with boiling point around 420 °C ; they are related with the volcanism associated with the massive sulphide occurrences,
— Essentially complex carbonic solutions related with the epizonal metamorphism of the Tizapa sequence,
— Aqueous solutions associated with ore veins with salinity decreasing with homogenization temperature from 10 to 1 eq. wt % NaCl and 350 to 150 °C ; K/Na at. ratio is high, near 0.3. There is no evidence for boiling. Geothermal gradient is estimated around 80 °C/km. All these characteristics are close to those encountered in other deposits of the same type.
The genetic model postulated from sulfur isotope data supports a selective remobilization of the massive or disseminated sulphides initially trapped in the Tizapa sequence by circulation of meteoric water in relation with the granitic intrusions.

Abstract
We present Hubble Space Telescope/Advanced Camera for Surveys (ACS) imaging of 23 very low surface brightness (μ

e,V
∼ 25–27.5) galaxies detected in the fields of four nearby galaxy groups. These objects were selected from deep optical imaging obtained with the Dragonfly Telephoto Array. Seven are newly identified, while most of the others had been seen previously in visual surveys of deep photographic plates and more recent surveys. Few have previously been studied in detail. From the ACS images, we measure distances to the galaxies using both the tip of the red giant branch method and the surface brightness fluctuations method. We demonstrate that the two methods are consistent with each other in the regime where both can be applied. The distances to 15 out of 20 galaxies with stable measurements are consistent with that of the targeted group within errors. This suggests that assuming group membership based solely on projected proximity is ∼75% successful in this regime. The galaxies are nearly round, with a median axis ratio of 0.85, and visually resemble dwarf spheroidal galaxies. The objects have a range of sizes, from R

Abstract
We report ∼2″ resolution Atacama Large Millimeter/submillimeter Array observations of the HCN (1–0), HCO+ (1–0), CO (1–0), CO (2–1), and CO (3–2) lines toward the nearby merging double-nucleus galaxy NGC 3256. We find that the high-density gas outflow traced in HCN (1–0) and HCO+ (1–0) emission is colocated with the diffuse molecular outflow emanating from the southern nucleus, where a low-luminosity active galactic nucleus (AGN) is believed to be the dominant source of the far-infrared luminosity. On the other hand, the same lines were undetected in the outflow region associated with the northern nucleus, whose primary heating source is likely related to starburst activity without obvious signs of an AGN. Both the HCO+ (1–0)/CO (1–0) line ratio (i.e., dense gas fraction) and the CO (3–2)/CO (1–0) line ratio are larger in the southern outflow (0.20 ± 0.04 and 1.3 ± 0.2, respectively) than in the southern nucleus (0.08 ± 0.01 and 0.7 ± 0.1, respectively). By investigating these line ratios for each velocity component in the southern outflow, we find that the dense gas fraction increases and the CO (3–2)/CO (1–0) line ratio decreases toward the largest velocity offset. This suggests the existence of a two-phase (diffuse and clumpy) outflow. One possible scenario to produce such a two-phase outflow is an interaction between the jet and the interstellar medium, which possibly triggers shocks and/or star formation associated with the outflow.
Post-Newtonian Magnetohydrodynamics
Authors: Nazari Elham , Roshan Mahmood 
Published: November 2018

Abstract
In this paper, we derive the post-Newtonian equations of the ideal magnetohydrodynamics. To do so, we use the modern approach to post-Newtonian theory, where the harmonic gauge is used instead of the standard post-Newtonian gauge, and find the post-Newtonian metric in the presence of the electromagnetic fields. We show that although the electric field does not contribute in the metric and curvature of the spacetime, the magnetic field appears in the time–time component of the metric. The appearance of the magnetic field, in principle, leads to new relativistic contributions to the magnetohydrodynamic governing equations. Therefore, using the post-Newtonian metric, we find the relativistic corrections to the magnetohydrodynamic equations up to the first post-Newtonian order. In addition, as usage of this derivation, we obtain a complete set of equations by which the behavior of a self-gravitating plasma can be determined in post-Newtonian gravity.

Published: November 2018

Introduction: The success of woman in following the exclusive breastfeeding program is determined by the significant effort of woman in giving breast milk and providing additional food to the baby. This problem can be solved by using the vibration effect on the postpartum mother's breast through DC Motor Vibratory (DMV) system. Therefore, the research aims to analyse the effectiveness of DMV among postpartum woman on giving breast milk. This intervention will assist to stimulate the prolactin hormone and to remove the oxytocin hormone of the breast milk.Method: The study is a quasi-experiment, with only post-test design and control group. The sample of study included 76 postpartum women in University of Sumatera Utara (USU) Hospital and maternity clinic in Medan, Indonesia with accidental sampling technique. The data were collected by using questionnaires, such as demographic questionnaire and observation of breast milk expenditure. The study was analysed by using the mann-whitney test.Result: The Result of study showed that the DMV could accelerate the process of breastfeeding for postpartum woman with the significant value of p <0.05.Conclusion: The research concluded that DMV can be applied in the postnatal care process, especially in stimulating breast milk expenditure.Keywords: DC Motor Vibrilatory Stimulus, postpartum women, breast milk
Un futur antérieur
Authors: Pilmis Olivier 
Published: November 2018

L’activité de prévision macroéconomique repose de manière décisive sur la description de la situation présente des économies, rapprochant l’activité de prévisionniste de celle du statisticien. En mobilisant la typologie proposée par A. Desrosières, ce texte met en évidence la façon dont l’activité de prévision articule quatre rapports différents aux « données », à partir desquels est évalué leur « réalisme ». Il étudie aussi certains des principes par lesquels il est possible de rendre compte de leur combinaison : division du travail, catégories de classement mobilisées par les prévisionnistes, instruments utilisés pour prévoir, temporalités des exercices de prévision.
Lire l’avenir économique dans la presse
Authors: Canu Roland 
Published: November 2018

Quel avenir économique peut-on lire dans la presse ? Nous proposons dans cette contribution d’opérer une focale sur les articles publiés dans la presse quotidienne nationale de 2007 à 2014, c’est-à-dire de rester à la surface des textes journalistiques eux-mêmes, pour y étudier les univers lexicaux, les rhétoriques employées et les sources convoquées. À partir d’un corpus composé de 522 articles – sélectionnés parce que s’y dévoile un « avenir économique » –, corpus notamment analysé à l’aide d’un logiciel lexicométrique, trois questionnements seront abordés : (a) quels sont les univers lexicaux spécifiques aux discours consacrés à cet avenir ? (b) Quelles sont les figures de l’expertise convoquées dans ces articles ? (c) Les représentations du futur présentées sont-elles seulement envisagées comme des projections dissociées d’une situation actuelle ou, à l’inverse, construites également à partir de celle-ci ? Ce parcours nous permet de styliser deux modèles bien différents d’écriture journalistique des futurs économiques : le premier inscrit ces futurs dans une séquentialité temporelle (présent-futur ou futur-présent) qui ouvre le champ des possibles à l’action politique et à des valeurs qui relèvent d’autres univers – au premier rang desquelles, les valeurs écologiques ; le second modèle isole les futurs économiques de ces mêmes actions et valeurs pour privilégier une rhétorique de l’évaluation des situations plausibles qui octroie un monopole de l’expertise à certains discours – en particulier ceux de la science économique.

Published: November 2018

Purpose: The aim of this research is to develop a two stages optimization model on make or buy analysis and quality improvement considering learning and forgetting curve. The first stage model is developed to determine the optimal selection of process/suppliers and the component allocation to those corresponding process/suppliers. The second stage model deals with quality improvement efforts to determine the optimal investment to maximize Return on Investment (ROI) by taking into consideration the learning and forgetting curve.Design/methodology/approach: The research used system modeling approach by mathematically modeling the system consists of a manufacturer with multi suppliers where the manufacturer tries to determine the best combination of their own processes and suppliers to minimize certain costs and provides funding for quality improvement efforts for their own processes and suppliers sides.Findings: This research provides better decisions in make or buy analysis and to improve the components by quality investment considering learning and forgetting curve.Research limitations/implications: This research has limitations concerning investment fund that assumed to be provided by the manufacturer which in the real system the fund may be provided by the suppliers. In this model we also does not differentiate two types of learning, namely autonomous and induced learning.Practical implications: This model can be used by a manufacturer to gain deeper insight in making decisions concerning process/suppliers selection along with component allocation and how to improve the component by investment allocation to maximize ROI. Originality/value: This paper combines two models, which in previous research the models are discussed separately. The inclusions of learning and forgetting also gives a new perspective in quality investment decision.

O processo de aquisição da lateral alveolar por gêmeos dizigóticos
Authors: Marques Tayse Feliciano , Lazzarotto-Volcão Cristiane 
Published: November 2018

Diversos estudos verificaram que a aquisição da linguagem por gêmeos ocorre de forma mais lenta do que por crianças não gêmeas (LURIA; YUDOVITCH, 1985; ZAZZO, 1978; RUTTER et al., 2003; RICE et al., 2014). Considerando-se tal constatação, este estudo descreve e analisa a aquisição da lateral alveolar por gêmeos dizigóticos, falantes monolíngues do português brasileiro (PB), a fim de verificar se ocorre atraso ou desvio nesse processo. Assim sendo, as tentativas de produções de /l/ em onset simples, realizadas pelos irmãos nas idades de 1:4 (um ano e quatro meses) a 4:0 (quatro anos), foram analisadas, atentando para os trajetos percorridos pelos sujeitos, sobretudo no que se refere às estratégias de reparo empregadas e à faixa etária em que adquiriram a lateral alveolar. De posse do percurso dos irmãos rumo à aquisição de /l/, os seus desempenhos foram comparados com os verificados na literatura e observou-se que os infantes apresentaram menos produções adequadas e, portanto, mais estratégias de reparo, principalmente no período entre 1:8 e 2:7. A partir de 2:8, no entanto, os irmãos manifestaram desempenhos semelhantes aos demonstrados na literatura, adquirindo a lateral alveolar dentro do que os estudos previram. Em linhas gerais, este estudo concluiu que os gêmeos não apresentaram atraso na aquisição da lateral alveolar. Observaram-se mais empregos de estratégias de reparo do que a adequada produção de /l/ nas faixas etárias iniciais. Apesar disso, as crianças equipararam-se com os dados da literatura, adquirindo /l/ entre 2:8 e 2:11.
Historias de la tercera edad: entre la continuidad y la alteridad
Authors: Klein Alejandro , Carcaño Erika 
Published: November 2018

Este artículo busca replantear algunas cuestiones de cómo nos acercamos a la vejez hoy, señalando que pasamos de términos relativamente claros (vejez y el envejecimiento) a una polisemia conceptos que entran dentro de lo que se denomina paradigmas anacrónicos o ambiguos. Se insiste en que el tema del envejecimiento es reemplazado probablemente por dos grandes polos: una estética no decrépitos y una actitud de memoria resiliente, los que son ejemplificados en dos estudios de caso. En ambos casos se plantea una etapa de alta experimentación subjetiva, tratando de localizar la situación del envejecimiento desde parámetros sociales y culturales más amplios.
A mobilidade presente no processo de segregação residencial: o caso da Região Noroeste de Goiânia/GO

Published: November 2018

Resumo
O presente artigo analisa o deslocamento e o rearranjo espacial de áreas segregadas na Região Noroeste de Goiânia. Nessa região, esse movimento foi orquestrado por forças políticas-partidárias juntamente com agentes empresariais. Esses atores materializaram no interior dos espaços segregados infraestrutura viária, serviços públicos e privados que deram curso a centralidades forjadas. Essas centralidades alteraram o endereço de pessoas que habitavam bairros da Região Noroeste de Goiânia, produzindo uma nova espacialização da segregação e um novo sentido aos bairros agora servidos por serviços públicos e privados. A partir dessa premissa, a pesquisa analisou as ações desempenhadas pelos agentes produtores do espaço urbano que deram curso à mobilidade da segregação residencial na Região Noroeste de Goiânia.

Abstract
The present article analyzes dislocation and spatial rearrangement in segregated areas in in the Northwest area in Goiânia. In this region, such movement stems to political and partisan powers along with businesspeople. Those agents materialized land transportation network, public and private services within segregated spaces which triggered forged centralization. Such centralization shifted people´s addresses, yielding a new specialization of segregation and a new meaning to neighborhoods with public and private services. With this premise, the research analyzed initiatives performed by urban space producing agents who enabled residential segregation mobility in the Northwest area in Goiânia.

Redes sociales, apoyo social y salud
Authors: Fernández Peña Roser 
Published: November 2018

En los últimos años, el ambiente social ha sido reconocido como un complejo	sistema estructural, cultural, interpersonal y psicológico con propiedades	adaptativas y de ajuste frente a determinadas situaciones relacionadas con los	procesos de salud-enfermedad y también como un sistema contenedor de	elementos estresares y/o amortiguadores del mismo. Ello justifica un creciente	interés hacia los recursos derivados de los vínculos sociales de los individuos así	como la relación existente entre las relaciones interpersonales y la salud de las	personas.	De este modo, conceptos como ";redes sociales,";, ";sistemas de apoyo comunitario";,	";apoyo social"; (social support), o ";recursos del entorno";, han sido conceptos clave	para el desarrollo de las líneas teóricas que han guiado las investigaciones que	relacionan las redes sociales y la salud.	Este artículo bibliográfico elaborado a partir de un trabajo de curso en el marco de	los estudios de doctorado pretende ser una aproximación al desarrollo conceptual y	empírico existente tanto desde el punto de vista antropológico como sanitario.
Measuring clients’ experiences with antenatal care before or after childbirth: it matters
Authors: Scheerhagen Marisja , Birnie Erwin , Franx Arie , van Stel Henk F. , Bonsel Gouke J. 
Published: November 2018

Background
When clients’ experiences with maternity care are measured for quality improvement, surveys are administered once, usually six weeks or more after childbirth. Most surveys conveniently cover pregnancy, childbirth and postnatal care all in one. However, the validity of measuring the experiences during pregnancy (antenatal experiences) after childbirth is unknown. We explored the relation between the measurement of antenatal experiences late in pregnancy but prior to childbirth (‘test’ or gold standard) and its retrospective measurement after childbirth (retrospective test). Additionally, we explored the role of modifying determinants that explained the gap between these two measurements.

Methods and Findings
Client’s experiences were measured by the ReproQuestionnaire that consists of an antenatal and postnatal version, and covers the eight WHO Responsiveness domains. 462 clients responded to the antenatal and postnatal questionnaire, and additionally filled out the repeated survey on antenatal experiences after childbirth. First, we determined the association between the test and retrospective test using three scoring models: mean score, equal or above the median score and having a negative experience. The association was moderate for having any negative experience (absolute agreement = 68%), for the median (absolute agreement = 69%) and for the mean score (ICC = 0.59). Multiple linear and logistic regression analysis for all three scoring models revealed systematic modifiers. The gap between antenatal and postnatal measurement was (partly) associated with clients’ experiences during childbirth and postnatal care and by professional discontinuity during childbirth but unrelated to the perceived health outcome.

Conclusions
The antenatal experiences should be measured before and not after childbirth, as the association between the antenatal experiences measured before and after childbirth is moderate.
