Pore-Scale Investigation of the Effect of Surfactant on Fluid Occupancies during Low-Salinity Waterflooding in Oil-Wet Carbonates
Authors: Mirchi Vahideh 
Published: October 2018

Abstract
Numerous studies reveal a moderate incremental oil recovery by injection of brine with a lower ionic strength than the connate brine in oil-wet systems. However, the combination of low salinity with surfactant flooding has been reported to give a vastly higher oil recovery. Despite overlooked laboratory investigations in this area, the underlying displacement mechanisms for the superior oil recovery have not been fully understood. In other words, there is inadequate direct evidence on pore-level displacement mechanisms accountable for the additional recovery.
In this work we have employed a micro-CT scanner to observe the pore-scale fluid configurations for in-situ investigation of contact angles and local displacement patterns under elevated temperature and pressure conditions. We present the results of various experiments involving flow through porous media using different wetting fluid systems on a set of miniature limestone core samples. The brine solutions are chosen as to allow us to investigate the impacts of surfactant and salinity on their associated oil–brine flow behaviors during waterflooding experiments. The core samples are subjected to a dynamic aging process before commencement of waterflooding tests.
Characterization of local wettability reveal an accelerated reversal toward neutral wetness due to the low-salinity surfactant effects. The in-situ contact angles sharply change by injection of small pore volumes of low-salinity surfactant solution. This impact is more profound when injection is succeeding a low-salinity waterflooding. In this study, the main mechanism responsible for the enhancement of oil recovery appears to be the improvement of brine frontal advance displacement to smaller pore constrictions and to the corners of pore elements. This is found to be a result of fast surfactant-induced wettability transition to neutral-wet condition.

Published: October 2018

Abstract
Hole cleaning and drilling rate remain major challenges once it comes to plan and drill workover and development wells. Inadequate hole cleaning is responsible for a large portion of all stuck pipe problems. Approximately 33% of stuck pipe incidents because of bad hole cleaning. The rate of penetration is extremely related to hole cleaning. If optimum hole cleaning can be ensured, that will lead to a high rate of penetration. To ensure perfect hole cleaning, it must be engineered. There are several correlations, mothed, designs, models, tools, charts, fields results, experimental studies and chemical materials to enhance the hole cleaning, but several of them are just based on theory and lack proper experimental data and not feasible in drilling operations. The knowledge of the size of cuttings, size of annulus, flow pattern, and down hole fluid properties cannot determined with high accuracy. This paper will show the influence of hole cleaning on the rate of penetration that will ensure optimum performance and mitigate stuck pipe problem and how the approach was applied during drilling operations. Knowledge from this paper will help in knowing hole cleaning more accurately and therefore facilitate improving drilling rate. The application of approach of Well drilling performance by using carrying capacity index and cuttings concentration in the annulus for ensuring perfect hole cleaning, and achieving enhanced well drilling performance by using optimum drilling parameters that can ensure minimum DSE. The Approach has been validated in the fields, and used to drill in challenging hole sections, and has improved the well drilling performance more than 55% and minimized DSE more than 54%.
Deterministic Blockmodeling of Two-Mode Binary Networks Using a Two-Mode KL-Median Heuristic
Authors: Brusco Michael , Stolze Hannah J. , Hoffman Michaela , Steinley Douglas , Doreian Patrick 
Published: October 2018

Abstract
Deterministic blockmodeling of a two-mode binary network matrix based on structural equivalence is a well-known problem in the social network literature. Whether implemented in a standalone fashion, or embedded within a metaheuristic framework, a popular relocation heuristic (RH) has served as the principal solution tool for this problem. In this paper, we establish that a two-mode KL-median heuristic (TMKLMedH) seeks to optimize the same criterion as the RH for deterministic blockmodeling. The TMKLMedH runs much faster than the RH, so many more restarts of the TMKLMedH can be accomplished when the two methods are constrained to the same time limit. Three computational comparisons of RH and TMKLMedH were conducted using both synthetic and real-world networks. In all three comparisons, the superiority of TMKLMedH was unequivocal.
Treatment efficacy of narrative family therapy for children and adolescents with diverse psychiatric symptomatology
Authors: Jørring Nina Tejs , Gjessing Jensen Karsten 
Published: October 2018

Abstract
Background: Little research has been undertaken on children and adolescents with psychiatric co-morbidity and this group is seldom subject to evidence-based treatment. Equally, there has been little research on creating an evidence base for Narrative Therapy, which means that narrative family therapy (NFT) is seldom available to children and adolescents with a psychiatric disorder.
Objective: A single group clinical design was used to examine the efficacy of NFT for children and adolescents with different diagnoses.
Method: Families receiving NFT from the Family Therapy Team (FTT) at the Child and Adolescent Mental Health Services (CAMHS) of the Capital Region of Denmark filled out psychometric measurements before and after treatment. Patients evaluated the burden of symptoms using Beck’s Youth Inventory (BYI), and parents evaluated their personal agency in relationship to their child’s psychiatric disorder using Parent Activation Measurement (PAM).
Results: We analyzed data from 48 patients and found a significant increase in median BYI measures of Self-Concept (40.5 to 46.0, p = 0.002) with an effect size of 0.60, decreases in BYI Depression Index (58.0 to 54.0, p = 0.030) with an effect size of –0.41, decreases in BYI Disruptive Behaviour Index (48.0 to 43.0, p = 0.030) with an effect size of –0.38, and a significant increase in PAM from 56.4 to 68.5, p = 0.001 with an effect size of 0.61.
Conclusion: Results from this study suggest that NFT has a direct positive effect on patients’ own evaluation of the burden of symptoms, and parents’ perceived personal agency regarding their child’s distress.
Main Nutritional and Environmental Risk Factors in Children with Leukemia from a Public Hospital of the State of Guanajuato, Mexico
Authors: Monroy-Torres Rebeca , Ibarra-Miranda Daniela , Sánchez Jaime Naves , Castillo-Chávez Angela 
Published: October 2018

Introduction::
The prevalence of leukemia in children aged under 19 years continues to
increase. Nutritional and environmental factors have been described as causes of their development,
and maternal breastfeeding, birth weight, exposure to cow’s milk or to contaminants before
1 year of age, and smoking have been studied.

Objective::
To analyze the main nutritional and environmental risk factors in children with Acute
Lymphoblastic Leukemia (ALL) in a public hospital in Guanajuato, Mexico.

Methods::
Analytical and cross-sectional study on 30 children under 18 years of age, with a confirmed
diagnosis of ALL in a public hospital in Guanajuato, Mexico. With the signed informed
consent of the children’s parents, a questionnaire was applied that collected and in which nutritional
risk factors (weeks of gestation and birth weight, breastfeeding, exposure to cow’s milk)
and environmental factors (smoking and exposure to arsenic) were evaluated. The frequencies and
Odds Ratios (OR) of the main nutritional and environmental risk factors were obtained.

Results::
Mean age was 8 ± 4 years with 38 ± 1 weeks of gestation, with a birth weight of 3,200 g
(range, 2,500-4,800 g). Fifty percent of the children consumed cow’s milk during their first year
of life (40% before 6 months of age); 33.3% received maternal milk for ≤6 months and 63% of the
parents had a positive smoking habit, with 66.6% of the participants living in cities with arsenic
levels falling outside of the norm.

Conclusion::
The main nutritional and environmental risk factors found were early complementary
feeding, cow’s milk prior to 1 year of age, a duration of breastfeeding of fewer than 6 months,
birth weight of >3,500 g, a positive smoking habit in the children’s parents, as well as exposure to
arsenic in drinking water. Identification of these risk factors could constitute an input for integrating
novel prevention alternatives and the nutritional management of leukemia.

Published: October 2018

In this manuscript, estimation of the periodic component of intensity having form periodic function multiplied by the linear trend of a non homogeneous Poisson process is discussed. The estimator is constructed using a single realization of the Poisson process observed in the interval 0,𝑛 . It is assumed that the period of the periodic component is known. The convergence of the Mean Square Error (MSE) of the estimator has been proved. In addition, asymptotic approximations to the bias, variance, and Mean Square Error (MSE) of the estimator have been proved. An asymptotic optimal bandwidth is also given.
Se Dworkin fosse ministro do STF, como ele julgaria a descriminalização do aborto?
Authors: Haeberlin Mártin 
Published: October 2018

O presente ensaio inicia como uma resenha de um artigo de Ronald Dworkin no qual, após apresentar uma base teórica para a interpretação dos direitos não enumerados, realizada desde sua noção de “direito como integridade”, sustenta ele a correção da decisão da Suprema Corte norte-americana no caso Roe v. Wade, entendendo que o direito à autonomia procriativa impede a proibição do aborto, pelos Estados, nos três primeiros meses de gestação. Após, o presente ensaio,descolando-se do propósito resenhista, apresenta a decisão da Suprema Corte brasileira sobre descriminalização do aborto referente ao Habeas Corpus nº 124.306, que descriminalizou o aborto nos três primeiros meses de gestação, propondo uma análise desta decisão com base no texto de Dworkin. Ao final, realiza-se uma avaliação do julgado em duas perspectivas. Em relação à primeira, conclui-se que o texto de Dworkin e a decisão do STF são importantes referências argumentativas em favor da descriminalização a ser eventualmente realizada via Poder Legislativo ou controle concentrado de constitucionalidade. Em relação à segunda, realiza-se uma crítica ao procedimento adotado pela Corte, por ter tomado a decisão em sede de controle incidental, ferindo assim a dialética (e, com ela, a integridade do direito) requerida a uma decisão dessa envergadura.
Evaluation of some morpho-physiological characteristics in strawberry under different moisture stress regimes
Authors: Aghaiee Negar , Zarei Leila , Cheghamirza Kianoosh 
Published: October 2018

BACKGROUND: The strawberry is one of the most important small fruits; it is widely cultivated in the world and is sometimes subjected to drought stress. Investigating the effects of drought stress on cultivar related plant physiology is necessary to broaden the knowledge of resistance mechanisms to drought. OBJECTIVE: The present study was conducted to investigate the morpho-physiological characteristics of drought tolerance and the relationships between these and strawberry fruit yield under short- and long-term drought stress conditions. METHODS: The effect of two strawberry cultivars, Queen Eliza and Parus, was examined under four moisture regimes. A short-term stress for one month and a long-term stress for four months were undertaken in greenhouse condition. RESULTS: The analysis of variance indicated significant differences between the cultivars for carotenoid content, relative water content, relative water loss, stomatal conductance and quantum yield of photosystem II under short-term stress and stomatal conductance, carotenoid content and membrane stability under long-term stress. Correlation analysis revealed that yield correlated positively with relative water content and quantum yield of photosystem II (Fv/Fm), under short- term and long- term stress. Using factor analysis, totally four factors were identified that accounted for 82.14% of the total variance. The factors were in decreasing order of influence yield components, photosynthesis, physiological characteristics and chlorophyll. CONCLUSIONS: Generally, ‘Parus’ was superior to ‘Queen Eliza’ in terms of measured traits under short and long-term stress conditions. It seems that measuring physiological traits is a convenient, simple and fast tool for screening genotypes for their drought tolerance.
Chemical composition and antibacterial activity of Origanum ramonense essential oil on the β-lactamase and extended- spectrum β-lactamase urinary tract isolates

Published: October 2018

<p class="Abstract">The aim of this study was to evaluate the antibacterial activity of <em>Origanum ramonense</em> essential oil extracted from the air-dried leaves against β-lactamase and extended-spectrum β-lactamase obtained from the patients with urinary tract infection. The essential oil was extracted by hydrodistillation and analyzed by GC–MS. In vitro antibacterial activity was studied using disc diffusion and microdilution methods. Twenty compounds were identified representing 97.8% of the total oil. The major components were carvacrol (84.6%), p-cymene (4.3%) and γ-terpinene (3.3%). The oil showed a broad spectrum of antibacterial activity against all tested isolates. <em>Staphylococcus aureus, S. epidermidis, Klebsiella pneumoniae</em> and <em>Enterobacter aerogenes</em> had the lowest minimum inhibitory concentration values (0.015 µg/mL) followed by <em>Escherichia coli</em> (0.14 µg/mL). The lowest susceptible strains to oil were <em>Pseudomonas aeruginosa, Proteus mirabilis, E. coli</em> 25922 and <em>P. aeruginosa</em> 10145. The bacteriostatic and bactericidal effects at concentrations as low as 0.015 µg/mL indicated the potent antibacterial activity of <em>O. ramonense</em>. </p><p><strong>Video Clip of Methodology:</strong></p><p>Disc Diffusion method: 2 min 16 sec <a href="https://www.youtube.com/v/HUZqSngRvmQ">Full Screen</a> <a href="https://www.youtube.com/watch?v=HUZqSngRvmQ">Alternate</a></p>
Le fond de cabane dans l'habitat rural Ouest-Européen : État des questions
Authors: Chapelot Jean 
Published: October 2018

Les fonds de cabane sont des structures bâties simples que l'on trouve en nombre plus ou moins grand dans les habitats ruraux du haut Moyen Age. Leur étude suppose un développement de l'archéologie des sites ruraux du haut Moyen Age, ce qui n'est pas le cas dans tous les pays d'Europe occidentale, et des méthodes de fouille rigoureuses, notamment des décapages fins de grande surface.
Quand ces conditions sont réunies, on s'aperçoit que les fonds de cabane sont avant tout des constructions associées à des maisons construites au niveau du sol. Leur fonction est alors soit celle d' annexes, utilisées pour diverses activités domestiques, comme le filage ou le tissage, ou artisanales, soit celle d'habitation des populations d'esclaves ou serviles. La situation est très différente dans les pays slaves où le fond de cabane est la structure d'habitat exclusive pendant tout le premier millénaire.
L'exemple de quelques sites continentaux ou anglais du tout début de la période des Migrations permet d'ajouter que parfois des habitats entièrement ou quasiment entièrement constitués de fonds de cabane ont été bâtis par ces populations lors de leur déplacement vers l'ouest.
L'extrême irrégularité de notre documentation, notamment dans la moitié sud de l'Europe, restreint notre connaissance mais nous pouvons dire que le fond de cabane, connu dès avant notre ère en Europe occidentale, utilisé pendant tout le premier millénaire, est surtout courant pendant les IVe-VIe siècles, puis sort progressivement d'emploi dans l'habitat rural. On en connaît cependant quelques utilisations du XIe siècle à nos jours.
L'interprétation de l'emploi du fond de cabane et de sa fonction ne peut recevoir une seule réponse pour toutes ces périodes et pour tous les secteurs d'utilisation. Il est indispensable d'envisager son étude à l'intérieur d'une analyse d'ensemble de l'habitat rural médiéval et en liaison avec les autres structures bâties mises au jour dans des fouilles de grande surface.
Satisfaction With Work-Life Balance: Couples with Egalitarian Practices in their Transition to First-Time Parenthood in Spain
Authors: González María José , Lapuerta Irene , Martín-García Teresa , Seiz Marta 
Published: October 2018

Cette étude analyse la satisfaction subjective des couples à double revenu quant à l’équilibre vie professionnelle-vie privée après la naissance de leur premier enfant. Nous avons effectué une analyse longitudinale qualitative sur 31 couples espagnols qui se répartissaient de manière égalitaire les tâches domestiques avant la naissance de l’enfant. Les couples participants ont été interrogés pendant la grossesse et environ 18 mois après la naissance. Nous avons étudié les sentiments individuels subjectifs de satisfaction quant à la répartition des tâches de soin à l’enfant. L’étude révèle que la moitié des couples a évolué vers une répartition traditionnelle des tâches, mais que cela n’a pas nécessairement entraîné d’insatisfaction concernant l’équilibre vie professionnelle-vie privée. La satisfaction d’équilibre vie professionnelle-vie privée dépend plus des attentes initiales que des arrangements spécifiques conclus au sein du couple.
Entre répression et prévention, retour sur l’antiterrorisme en France
Authors: Fragnon Julien , Roudier Karine 
Published: October 2018

Si l’état d’urgence marque par sa durée une rupture dans le dispositif antiterroriste français, notre article démontre qu’il s’inscrit dans une histoire longue de l’antiterrorisme initiant assez tôt une inclination préventive. Ce dernier est marqué par la volonté du législateur de réprimer plus sévèrement le terrorisme par un dispositif dérogatoire au droit commun. Ce régime pénal spécifique et incrémental permettait aussi à l’Etat de lutter efficacement contre le terrorisme sans user de dispositifs d’exception grâce à la place centrale du juge judiciaire. Mais la campagne d’attentats débutée en 2015 favorisa l’organisation de la lutte dans une logique d’anticipation. Cette stratégie prit la forme de mesures de police administrative qui, de fait, sont soustraites au contrôle du juge judiciaire. Malgré un degré de perfectionnement élevé du dispositif et une érosion continue du rapport sécurité/liberté en démocratie, le système ne semble cependant jamais assez adapté pour rassurer la population et se voit renforcé régulièrement après chaque attentat.
Aux limites de la diversité, la religion : un angle mort des politiques de lutte contre les discriminations
Authors: Doytcheva Milena 
Published: October 2018

Alors que les convictions religieuses font partie des libertés fondamentales et qu’elles sont un éléments intégrant du dispositif juridique antidiscriminatoire depuis l’article 13 du Traité d’Amsterdam de 1997 et la première loi française qui transpose les mesures législatives européennes en 2001 1 , la « diversité religieuse » n’est pas visée par l’entreprise et n’y est pas non plus tout à fait admise, ou à condition d’être rendue invisible. C’est une lecture extensive des principes de la laïcité et de la loi de 2004 sur les signes religieux à l’école qui justifient cette posture 2 . Or, tout comme la législation sur l’école qui se veut en théorie générique, ces interdictions visent majoritairement dans les faits une population seule et unique, de confession musulmane.
Islam-République-Armée : une poursuite de la laïcité par d’autres moyens ?
Authors: Frécon Eric 
Published: October 2018

L’armée française doit tenir compte de la présence de musulmans dans ses rangs. Etant donné le nombre croissant des opérations extérieures en général et les exigences du milieu maritime en particulier, se pose la question de l’islam au sein de la Marine nationale et la façon de le vivre au quotidien, avec les outils de la laïcité et dans le cadre du projet républicain. Or, dans la lignée de la loi de 1905 et après une prise de conscience dans les années 1990, tout est mis en œuvre pour veiller à la « liberté » de pratique (piliers de l’islam et nourriture halal), à l’« égalité » de traitement (mise en place des aumôniers musulmans en 2005) et à la « fraternité » face au combat, que l’ennemi soit musulman ou pas. Reste à savoir si les autorités n’en font pas trop, quitte à laisser la porte ouverte aux excès. A moins qu’il ne s’agisse que d’efforts de façade ? Il n’empêche, jusqu’à présent, un pragmatisme éclairé permet aux musulmans et non-musulmans de vivre en bonne intelligence.
Le tribunal de l’amirauté et les usages du métier. Une histoire « par en bas » du monde de la pêche (Dieppe, xviii e siècle)
Authors: Grancher Romain 
Published: October 2018

Cet article étudie l’univers normatif des acteurs d’un monde de la pêche d’Ancien Régime à partir du cas de Dieppe au XVIII e siècle. La première partie présente le fonctionnement du tribunal local de l’amirauté, qui exerçait sous l’Ancien Régime une compétence exclusive sur les choses de la mer et connaissait par conséquent des litiges entre armateurs, maîtres de bateau et matelots pêcheurs. Alors que l’historiographie maritime s’est longtemps focalisée sur les fonctions de contrôle et de surveillance dévolues à cette juridiction, les archives de la pratique judiciaire révèlent un tableau plus contrasté. Dans une proportion écrasante, les affaires portées devant les officiers de l’amirauté se résument à de petits conflits résultant d’accidents de pêche, de contrats rompus ou encore de salaires non versés, relevant autrement dit d’une procédure civile. Toutefois, un examen attentif de cette poussière de litiges permet de mettre en évidence les usages sociaux de la justice faits par les plaideurs. Loin d’être simplement un instrument de contrôle du rivage et de ses populations, le tribunal de l’amirauté remplit des fonctions qui débordent largement le terrain de la seule résolution des conflits du travail pour investir ceux de la certification des contrats ou de l’expertise des dommages. La dernière partie part du problème de la pluralité des systèmes normatifs en vigueur dans les mondes de la pêche d’Ancien Régime et montre comment il est possible de considérer le tribunal d’amirauté comme l’instance de production d’un droit local « venu d’en bas ».
The Role of WNT Signaling in Mature T Cells: T Cell Factor Is Coming Home
Authors: van Loosdregt Jorg , Coffer Paul J. 
Published: October 2018

Abstract
T cell factor, the effector transcription factor of the WNT signaling pathway, was so named because of the primary observation that it is indispensable for T cell development in the thymus. Since this discovery, the role of this signaling pathway has been extensively studied in T cell development, hematopoiesis, and stem cells; however, its functional role in mature T cells has remained relatively underinvestigated. Over the last few years, various studies have demonstrated that T cell factor can directly influence T cell function and the differentiation of Th1, Th2, Th17, regulatory T cell, follicular helper CD4+ T cell subsets, and CD8+ memory T cells. In this paper, we discuss the molecular mechanisms underlying these observations and place them in the general context of immune responses. Furthermore, we explore the implications and limitations of these findings for WNT manipulation as a therapeutic approach for treating immune-related diseases.
