Development and Application of a New Two-Phase Scaleup Method Based on Tensor Permeabilities
Authors: Pickup G. E. , Sorbie K. S. 
Published: April 2018

Abstract
Scaleup (or pseudo-isation) techniques for multiphase flow must be applied in order to capture the details of small-scale fluid mechanics and heterogeneity in coarse grid simulation models. Current methods of two-phase scaleup are not specifically designed to handle situations where strong fluid crossflow occurs. This may arise either through the fluid displacement process, for example viscous crossflow, or where there are certain types of geological structure. Such structures occur frequently in hydrocarbon reservoirs, in the form of crossbedded sandstones. When crossflow is significant, conventional scaleup methods usually deal with this by deriving directional pseudo-relative permeabilities.
A new scaleup method, based phase permeability tensors, has been developed to treat the general two phase case where strong crossflows may occur. In the new method, the tensor elements, i.e. the tensor pseudo-functions, depend on water saturation. This method represents both an extension of single phase tensor scaleup and a generalisation of conventional pseudo-isation techniques. As in conventional scaleup procedures, the pseudo-functions also depend on the ratio of viscous to capillary forces. In particular, when the flood is capillary dominated, oil trapping may occur (in a water-wet rock). Tests carried out on layered models show that the new method is capable of capturing the correct amount of trapping, and can perform scaleup successfully for a range of viscous/capillary ratios.
The method has been validated by showing that it accurately reproduces fine grid calculations using tensors on a coarser grid. In addition, it has been applied to the scaleup of small scale models of ripple-bedded facies where fluid crossflows are likely to occur. Both deterministic and stochastic representations were simulated. Results show that the oil recovery is sensitive to the presence of low permeability barriers, such as low permeability bottomsets in the ripple beds. The results highlight the importance of having a detailed model of the fine-scale permeability structure in order to predict oil recovery accurately.

<strong>Feminist literary criticism</strong> is a <a title="Literary criticism" href="https://en.wikipedia.org/wiki/Literary_criticism">literary criticism</a> knowledgeable by <a title="Feminist theory" href="https://en.wikipedia.org/wiki/Feminist_theory">feminist theory</a>, or, more broadly, by the politics of <a title="Feminism" href="https://en.wikipedia.org/wiki/Feminism">feminism</a>. It uses feminist principles and ideology to critique the language of literature. This school of thought seeks to analyze and describe the ways in which literature portrays the narratives of male domination by exploring the economic, social, political, and psychological forces embedded within literature. Feminism emerged as an important force in the western world in 1960s when women realized the attitude of their male colleagues who swore about equality, was actually the strategy used by them to keep women subservient, then a revolution by women to fight against them, and against racism and sexism was felt. This awakening spread over and as a result feminist criticism emerged on as an off –shoot of women’s Liberation Movement. Beginning with the interrogation of male-centric literature that portrayed women in a demeaning and oppressed model, theorist such as Marry Ellman, Kate Millet and Germaine Greer challenged past imaginations of the feminine within literary scholarship. It is very important for us to know that who these women writers are, what did they write and what were the sources of their writings. The present paper focuses on some of the above said important aspects of feminist writings and some of famous feminist writers also.
Reflexiones sobre la formación técnica gratuita en la ciudad de Medellín
Authors: Palacio Vásquez Marta Lucia 
Published: April 2018

La educación técnica busca formar desde tres grandes dimensiones: el ser, el saber y el hacer, predominando más ésta última. Sin embargo, en algunas instituciones de la ciudad de Medellín se desea hacer una reflexión sobre cómo puede influir la gratuidad de esta educación en el perfil ocupacional que sale al mercado laboral, debido a que el hacer se está quedando relegado por falta de saber y de ser, porque no hay vocación de estudio en las personas que ingresan a capacitarse, lo que hay es un deseo de no perder una oportunidad de becas, aunque no sea lo que en verdad se anhela estudiar. El objetivo de ésta reflexión es identificar personas idóneas que deseen estudiar becados programas técnicos, para que el mercado laboral actual cuente con personas que aman lo que hacen, y no con técnicos que solamente lo hacen porque no tomaron la decisión de decir no oportunamente a una beca brindada por la Gobernación; también se busca un perfil docente adecuado a este tipo de población becada para que con su enseñanza transforme y enamore de la técnica al estudiante.
Las TIC: estrategia para mejorar la competencia lectora-interpretativa en el área de lenguaje
Authors: Toro Henao Carlos Mauricio 
Published: April 2018

El objetivo de esta investigación se centró en optimizar los procesos de lectura interpretativa (área de lenguaje), en los estudiantes del grado Undécimo D de la Institución Educativa Gilberto Alzate Avendaño, de la ciudad de Medellín, con el uso de las Tecnologías de la Información y Comunicación (TIC). El estudio se enmarcó en una metodología cuantitativa, específicamente el método cuasi-experimental y descriptivo (Valenzuela y Flores, 2012). Además, se complementó con una aproximación de enfoque cualitativo (Suárez, 2001). Los resultados permitieron demostrar que la implementación de las TIC en el universo escolar apoyan los procesos pedagógicos y el acceso al campo del conocimiento; igualmente, dinamizan las relaciones entre el docente, el estudiante y los núcleos temáticos de enseñanza, por cuanto generan un aprendizaje con sentido desde una motivación constante (Ferro, Martínez y Otero, 2009).
Impact of sanitation monitoring approaches on sanitation estimates in Sub-Saharan Africa
Authors: Munamati Muchaneta , Nhapi Innocent , Misi Shepherd Nimrod 
Published: April 2018

AbstractThe Government and the Joint Monitoring Programme for Water and Sanitation (JMP) sanitation monitoring approaches often produce conflicting sanitation estimates reflecting an inconsistent view of sanitation performance. One of the possible reasons for conflicting estimates is the differences in definitions of ‘improved sanitation access’. This paper presents an assessment of definitions used in Sub-Saharan Africa and an analysis of the impact of the two monitoring approaches on sanitation estimates. Results showed that 40.0% of the 35 countries analysed used stricter definitions than the JMP definition, while 22.2 and 37.1% used more lenient definitions and JMP-like definitions respectively. Independent samples t-test results showed significant differences (p≤ 0.05) between the Government and JMP sanitation estimates. The Bland–Altman analysis showed that on average the Government approach measured more than the JMP approach and that the highest frequencies of negative differences were obtained from countries using JMP-like definitions. The study concludes that the overestimation of Government sanitation estimates could not have been due to use of lenient definitions, but other factors such as the quality and quantity of data sources and methods of data analysis could have played a crucial role. Harmonization of definitions and methods in all survey instruments is, however, crucial to ensuring consistency in the post-2015 sanitation monitoring.
Repetitive Transcranial Magnetic Stimulation Reverses Aβ1–42-induced Dysfunction in Gamma Oscillation during Working Memory
Authors: Bai Wenwen , Liu Tiaotiao , Dou Mengmeng , Xia Mi , Lu Jun , Tian Xin 
Published: April 2018

Background:
Alzheimer's disease (AD) is a neurodegenerative disease that gradually induces cognitive
deficits in the elderly and working memory impairment is typically observed in AD. Amyloid-β peptide
(Aβ) is a causative factor for the cognitive impairments in AD. Gamma oscillations have been recognized to
play important roles in various cognitive functions including working memory. Previous study reported that
Aβ induces gamma oscillation dysfunction in working memory.

Objective:
Although repetitive transcranial magnetic stimulation (rTMS) represents a technique for noninvasive
stimulation to induce cortical activity and excitability changes and has been accepted for increasing brain
excitability and regulating cognitive behavior, the question whether rTMS can reserve the Aβ-induced gamma
oscillation dysfunction during working memory remains unclear. The present study aims to investigate the
effect of rTMS to the Aβ-induced gamma oscillation dysfunction during working memory.

Method:
The present study investigates the rTMS-modulated gamma oscillation in Aβ1-42-induced memory
deficit. Adult SD rats were divided into four groups: Aβ, Con, Aβ+rTMS and Con+rTMS. 16-channel local
field potentials (LFPs) were recorded from rat medial prefrontal cortex while the rats performed a Y-maze
working memory task. Gamma oscillation among LFPs was measured by coherence.

Results:
The results show that rTMS improved the behavior performance and enhanced gamma oscillation for
the Aβ-injected subjects.

Conclusion:
These results indicate that rTMS may reserve the Aβ-induced dysfunction in gamma oscillation
during working memory and thus result in potential benefits for working memory.
Youth Mental Health Services Utilization Rates After a Large-Scale Social Media Campaign: Population-Based Interrupted Time-Series Analysis
Authors: Booth Richard G , Allen Britney N , Bray Jenkyn Krista M , Li Lihua , Shariff Salimah Z 
Published: April 2018

Background
Despite the uptake of mass media campaigns, their overall impact remains unclear. Since 2011, a Canadian telecommunications company has operated an annual, large-scale mental health advocacy campaign (Bell Let’s Talk) focused on mental health awareness and stigma reduction. In February 2012, the campaign began to explicitly leverage the social media platform Twitter and incented participation from the public by promising donations of Can $0.05 for each interaction with a campaign-specific username (@Bell_LetsTalk).

Objective
The intent of the study was to examine the impact of this 2012 campaign on youth outpatient mental health services in the province of Ontario, Canada.

Methods
Monthly outpatient mental health visits (primary health care and psychiatric services) were obtained for the Ontario youth aged 10 to 24 years (approximately 5.66 million visits) from January 1, 2006 to December 31, 2015. Interrupted time series, autoregressive integrated moving average modeling was implemented to evaluate the impact of the campaign on rates of monthly outpatient mental health visits. A lagged intervention date of April 1, 2012 was selected to account for the delay required for a patient to schedule and attend a mental health–related physician visit.

Results
The inclusion of Twitter into the 2012 Bell Let’s Talk campaign was temporally associated with an increase in outpatient mental health utilization for both males and females. Within primary health care environments, female adolescents aged 10 to 17 years experienced a monthly increase in the mental health visit rate from 10.2/1000 in April 2006 to 14.1/1000 in April 2015 (slope change of 0.094 following campaign, P<.001), whereas males of the same age cohort experienced a monthly increase from 9.7/1000 to 9.8/1000 (slope change of 0.052 following campaign, P<.001). Outpatient psychiatric services visit rates also increased for both male and female adolescents aged 10 to 17 years post campaign (slope change of 0.005, P=.02; slope change of 0.003, P=.005, respectively). For young adults aged 18 to 24 years, females who used primary health care experienced the most significant increases in mental health visit rates from 26.5/1000 in April 2006 to 29.2/1000 in April 2015 (slope change of 0.17 following campaign, P<.001).

Conclusions
The 2012 Bell Let’s Talk campaign was temporally associated with an increase in the rate of mental health visits among Ontarian youth. Furthermore, there appears to be an upward trend of youth mental health utilization in the province of Ontario, especially noticeable in females who accessed primary health care services.
Soft-sediment deformation structures induced by seismic activity in the San Pedro el Alto area, Acambay graben, Mexico
Authors: Velázquez-Bucio M. Magdalena , Garduño-Monroy Víctor Hugo 
Published: April 2018

Soft-sediment deformation structures identified in lacustrine sediments of the San Pedro el Alto area, within the Acambay graben, Mexico, can be attributed to Pleistocene-Holocene seismic events. The analysis of these deformation structures, seismites, is a key tool for the characterization of parameters such as the intensity and magnitude of the events, and the measurement of the affected area. Analysis of the shape, distribution, abundance and genesis of these secondary structures in lacustrine basins, also provide guidelines for assessing seismic hazard.
The analysis of seismites enabled the identification of three M ≥ 5 earthquakes, minimum magnitude required for the formation of such structures, these on ESI 2007 scale (Environmental Seismic Intensity Scale) correspond to VII-X intensities. The structures were identified with coseismic stratigraphy analysis in three trenches and three sediment cores from the dam within the locality. The basin infill consists of lacustrine sediments with intercalation of volcanic material. The soft-sediment deformation structures appear in different sectors of the study area and consist of surficial ruptures, vertical displacements, slumps, pseudonodules, clastic dikes, cracks filled with recent material, and diapir-like and load-flame structures.

Published: April 2018

En este trabajo se ofrece una respuesta conceptualista a la crítica de circularidad en la adquisición y posesión de conceptos observacionales, esgrimida por Peacocke. Tal respuesta consiste en proponer un proceso de categorización subpersonal que pueda hacer disponibles los conceptos observacionales relevantes con antelación a que el sujeto se encuentre en la experiencia perceptiva correspondiente. Ofrezco sustento empírico a esta respuesta a partir de resultados experimentales en ciencias cognitivas relacionados con la percepción del color. Estos experimentos evidencian influencias lingüístico-conceptuales en el procesamiento temprano de estímulos perceptivos, de un modo que respeta los límites establecidos por las categorías lingüísticas de los hablantes. Por último, y tras responder algunas posibles objeciones, concluyo que hay razones tanto conceptuales como empíricas para defender una respuesta conceptualista a la crítica de circularidad.

Lemuru fish is one of fishery commodity that has high economical value and one of fish that most catched by fisherman in Bali Strait. Lemuru fish had been caught in Bali Strait was fluctuating every month and every years. This condition was related with food source of Lemuru fish such as phytoplankton and zooplankton. So this research was conducted to explained the relationship phytoplankton and zooplankton abundance with Lemuru fish catched in Bali strait. This study focus in Bali strait during March until May 2017. Determination of sampling point used area sampling method while water sampling occured in surface water with pouring method. Total of phytoplankton and zooplankton abundance in Bali strait in March until May had formed the sinusoidal model with their abundance ranged 301 ind/L – 604 ind/L and 7 ind/L – 12 ind/L. Plankton abundance in Bali strait in March until May (transisonal season 1) was categorized low abundance if compared with plankton abundance in another season. The low value of phytoplankton abundance caused by non upwelling phenomenon and grazing process and the low abundance of zooplankton caused by low rate of zooplankton and predation by Lemuru fish. Phytoplankton and zooplankton abundance had strong relationship with Lemuru fish catched with correlation coefficient value 0.76 and 0.69. This condition caused by phytoplankton and zooplankton are source of Lemuru fish food.
