Authors: Akbar Noreen Sher , Butt Adil Wahid 
Published: January 2019

Abstract
In this article, we have investigated peristaltic mechanisms in a two dimensional nonuniform channel filled with Herschel–Bulkley fluid. Problem is studied under the assumptions of long-wavelength and low-Reynolds-number approximation. The fluid flow is investigated in the wave frame of reference moving with the velocity of the peristaltic wave in a channel. Exact solutions for the velocity field, temperature profile, stream functions, and pressure gradient are obtained and illustrated graphically for different parameters of interest such as α (angle of inclination), τ (the ratio of yield stress), φ (amplitude ratio), Pr (Prandtl number), and Q (mean flow rate) etc.
Induced Magnetic Field Effects on Peristaltic Flow in a Curved Channel
Authors: Noreen Saima 
Published: January 2019

Abstract
The peristaltic flow of an incompressible viscous fluid in a curved channel is investigated. The flow analysis is conducted in the presence of an induced magnetic field. A long-wavelength and low-Reynolds number approach is followed. The stream function, pressure gradient, magnetic force function, induced magnetic field, and current density are constructed. We observed that symmetry in the profiles of u and ϕ is disturbed because of curvature effects. For larger values of curvature k, results of planar channel are deduced. The effects of significant parameters have been portrayed and discussed.

By predicting sensory consequences of actions, humans can distinguish self-generated sensory inputs from those that are elicited externally. This is one mechanism by which we achieve a subjective sense of agency over our actions. Corollary discharge (CD) signals—“copies” of motor signals sent to sensory areas—permit such predictions, and CD abnormalities are a hypothesized mechanism for the agency disruptions in schizophrenia that characterize a subset of symptoms. Indeed, behavioral evidence of altered CD, including in the oculomotor system, has been observed in schizophrenia patients. A pathway projecting from the superior colliculus to the frontal eye fields (FEFs) via the mediodorsal thalamus (MD) conveys oculomotor CD associated with saccadic eye movements in nonhuman primates. This animal work provides a promising translational framework in which to investigate CD abnormalities in clinical populations. In the current study, we examined whether structural connectivity of this MD–FEF pathway relates to oculomotor CD functioning in schizophrenia. Twenty-two schizophrenia patients and 24 healthy control participants of both sexes underwent diffusion tensor imaging, and a large subset performed a trans-saccadic perceptual task that yields measures of CD. Using probabilistic tractography, we identified anatomical connections between FEF and MD and extracted indices of microstructural integrity. Patients exhibited compromised microstructural integrity in the MD–FEF pathway, which was correlated with greater oculomotor CD abnormalities and more severe psychotic symptoms. These data reinforce the role of the MD–FEF pathway in transmitting oculomotor CD signals and suggest that disturbances in this pathway may relate to psychotic symptom manifestation in patients.SIGNIFICANCE STATEMENTPeople with schizophrenia sometimes experience abnormalities in a sense of agency, which may stem from abnormal sensory predictions about their own actions. Consistent with this notion, the current study found reduced structural connectivity in patients with schizophrenia in a specific brain pathway found to transmit such sensorimotor prediction signals in nonhuman primates. Reduced structural connectivity was correlated with behavioral evidence for impaired sensorimotor predictions and psychotic symptoms.

Political science and mass communication studies have proven long ago that media outlets can affect public opinion. This is especially important when political choices are made. The media can determine how the public will react to changes. In our case, we delve into a potential threat of a biased public opinion (favorable to certain business subjects, politicians or others parties) being formed. This relates to the media outlets or organizations stepping over the boundaries of ethics for a chance to make a profit from certain interested individuals, organizations or companies.
This study addresses the problem of how the changes in the legislation of alcohol control have been reflected in the Lithuanian online newspapers 15min.lt, Delfi.lt and Lrytas.lt. Our study object pertains to how the changes in the law of alcohol control are being reflected. The aim of this article is to examine how these changes of law have been reflected in Lithuanian media.
A qualitative case study was conducted using content analysis. The results of the research show that the abovementioned Lithuanian online newspapers reflected a rather one-sided evaluation of the law changes. Most of the changes were reflected in a negative way; there were more negative than positive publications informing about the changes.
Although similar tendencies have been identified in all the online newspapers, Lrytas.lt happened to stand out. There were publications that had no clear sources of information; the authors of the publications were not mentioned as well. Furthermore, there were publications criticizing not the changes themselves but certain members of the parliament. The appliance of ethical norms was deemed to be more characteristic of Delfi.lt and 15min.lt.

Evaluación del rendimiento y periodo de descanso de tres pastos de piso
Authors: Brenes Gamboa Saúl 
Published: January 2019

Se evaluó la producción de biomasa y la calidad nutritiva de tres pastos de piso: Brachipara, Brachiaria decumbens y Cynodon nlemfuensis a diferentes intervalos de pastoreo en Turrialba de Cartago, durante un periodo de evaluación de dos años. Para los tres pastos la producción de materia verde que se obtuvo fue más de 11 mil Kg/MV/ha, el día antes de iniciar el pastoreo. Se observó una característica importante en cuanto a la producción de materia verde con el pasto Brachipara que fue a los 35 días de 11.367 Kg/ha. Es importante recalcar que este aumento coincide con la máxima producción de materia seca y proteína cruda, siendo este en forma conspicua un momento óptimo de reingreso de los animales al potrero para este material y bajo las condiciones donde se llevó el ensayo. Con respecto al porcentaje de materia seca se observó un comportamiento que oscila entre un 20 y 30%, obteniéndose los mayores valores con el C. nlemfuensis, entre los 42 y 56 días después del pastoreo En el Brachipara y B. decumbens se observaron los mayores contenidos de proteína cruda que fueron de 13% a los 21 días y de 15% a los 35 y 42 días respectivamente. El menor contenido de proteína al final del periodo se presentó en C. nlemfuensis, el cual fue de 7% a los 56 días, sin embargo a los 21 días alcanzó el mismo porcentaje de proteína que los materiales anteriores. Finalmente, el Brachipara es el pasto que ocupa un periodo más corto para recuperarse, alrededor de 35 días en comparación con los otros pastos evaluados, ya que tanto el C. nlemfuensis como la B. decumbens requieren aproximadamente 49 días de recuperación, según los datos obtenidos en el periodo de estudio.
Referencias gnósticas en la Enéada I, 6 de Plotino
Authors: Miranda Leonel Miranda 
Published: January 2019

El ambiente político, social y económico del Imperio romano, durante la segunda mitad del siglo iii, puede considerarse sombrío, especialmente entre los años 249-274. Para la época, el pensamiento del filósofo neoplatónico Plotino (205-270) despertó un gran interés, pues logró articular en un lenguaje filosófico las experiencias espirituales y orientó espiritualmente a quienes no eran filósofos. Entre quienes asisten a su escuela, encontramos cristianos, pertenecientes a diferentes sectas gnósticas. La relación con el gnosticismo pasa por diferentes etapas; en la primera, se nota una serie de convergencias, que disimulan bastante los desacuerdos. El autor de este artículo analiza desde el esquema ascensional o de Anábasis propuesto en la Enéada I, 6, las convergencias con el gnosticismo, principalmente de tipo valentianiano, sethiano u ofita. Además de las convergencias lingüísticas, la correspondencia entre el Neoplatónico y los gnósticos es de contenido: el regreso del alma a la patria (=padre), la purificación, la mediación del Intelecto y ciertos atisbos sobre la patria.
Excessive social media users demonstrate impaired decision making in the Iowa Gambling Task
Authors: Meshi Dar , Elizarova Anastassia , Bender Andrew , Verdejo-Garcia Antonio 
Published: January 2019

Background and aims
Online social networking sites (SNSs) like Facebook provide users with myriad social rewards. These social rewards bring users back to SNSs repeatedly, with some users displaying maladaptive, excessive SNS use. Symptoms of this excessive SNS use are similar to symptoms of substance use and behavioral addictive disorders. Importantly, individuals with substance use and behavioral addictive disorders have difficulty making value-based decisions, as demonstrated with paradigms like the Iowa Gambling Task (IGT); however, it is currently unknown if excessive SNS users display the same decision-making deficits. Therefore, in this study, we aimed to investigate the relationship between excessive SNS use and IGT performance.

Methods
We administered the Bergen Facebook Addiction Scale (BFAS) to 71 participants to assess their maladaptive use of the Facebook SNS. We next had them perform 100 trials of the IGT to assess their value-based decision making.

Results
We found a negative correlation between BFAS score and performance in the IGT across participants, specifically over the last block of 20 trials. There were no correlations between BFAS score and IGT performance in earlier blocks of trials.

Discussion
Our results demonstrate that more severe, excessive SNS use is associated with more deficient value-based decision making. In particular, our results indicate that excessive SNS users may make more risky decisions during the IGT task.

Conclusion
This result further supports a parallel between individuals with problematic, excessive SNS use, and individuals with substance use and behavioral addictive disorders.

Published: January 2019

This article presents an overview of 40 literary sources regarding injuries caused by baby walkers. The data from the first studies on the submitted subjects (1981) to the present were estimated for the first time in Russian scientific literature.
Significant variations in the structure and volume of injuries worldwide were shown. This may be caused by the difference in the living quarter structure, cultural features, errors in data collection, accuracy of data sources, and improvement of the devices. However, in our opinion, two factors have the greatest influence: the design and specific technical solution of such devices and the presence of stairs accessible to the child in a residential building.
In addition, the possibility of children acquiring thermal trauma in a walker was described, including the ability to reach dangerous items, such as heaters, ashtrays, electrical connections, and hot drinks, including poisons.
The danger of walkers as a factor influencing the normal formation of bipedal locomotion and motor pattern was indicated.
The authors underline the need to inform the public regarding the dangers of walkers as much as possible or to introduce a complete ban on their use, which was done in Canada in 2004 that led to a decrease in the level of child injuries.
(Trans)formação da docência: contribuições das experiências de vida à formação inicial de professores

Published: January 2019

Esse relato de uma experiência realizada na disciplina Didática Geral, oferecida aos cursos de licenciatura na Universidade Federal de Uberlândia, objetiva compreender o universo dos processos de formação inicial de professores a partir da autoformação. A proposta do Projeto de Docência é apresentada no início do semestre enquanto instrumento reflexivo, visando à assunção da profissão docente. Constatamos nos primeiros momentos que a elaboração de tal documento provoca resistências; entretanto, uma vez superadas as dificuldades iniciais, o mergulho em busca de si é inevitável – os estudantes descobrem que o sentido do aprendizado está no próprio viver. Apesar de a proposta de desenvolvimento do Projeto de (trans)formação para a docência ser comum às diferentes turmas, em semestres variados, a produção de cada uma delas apresenta resultados singulares. A ênfase está no reconhecimento tanto dos saberes formais externos aos indivíduos quanto dos saberes subjetivos/não formalizados que as pessoas transportam consigo, os quais são tecidos em suas experiências de vida, de acordo com contextos socioculturais diversificados. Depreendemos que as narrativas (auto)biográficas, ao longo do processo de formação de professores, fornecem elementos valiosos para a autorreflexão de alunos e professores, além de possibilitarem a intervenção problematizadora do formador sobre concepções, crenças e saberes dos licenciandos em relação à docência, ao promoverem a sua (trans)formação.

Authors: Francisco Marcos Vinicius , Coimbra Renata Maria 
Published: January 2019

Nesta investigação analisou-se o processo de apropriação de objetivações culturais, favorecedoras da resiliência em-si em jovens expostos ao bullying escolar. Assumiu-se como referencial a Teoria Histórico-Cultural que tem como base epistemológica o Materialismo Histórico Dialético. Participaram da pesquisa, 06 jovens de uma escola pública, do interior do estado de São Paulo, Brasil. Entrevistas semiestruturadas foram realizadas, a fim de problematizar fotografias e filmagens. Os resultados apontaram que os participantes vêm se apropriando de algumas objetivações humanas, tais como as atividades e espaços que contemplam o lazer, a música, a literatura e outras manifestações artísticas. Embora tais objetivações os tenham conduzido ao enfrentamento do bullying escolar, por meio da resiliência em-si, desenvolvida na relação dialética entre mecanismos mediadores de risco e proteção, tal enfrentamento é pontual, pois os estudantes continuam centrados no modelo de organização social que produz tal manifestação de violência.
Novel Observations of Salinity Transport in Low-Salinity Waterflooding
Authors: Al-Ibadi Hasan , Stephen Karl , Mackay Eric 
Published: January 2019

Summary
Low-salinity waterflooding (LSWF) is a promising process that could lead to increased oil recovery. To date, the greatest attention has been paid to the complex oil/water/rock chemical reactions that might explain the mechanisms of LSWF, and it is generally accepted that these result in behavior equivalent to changing oil and water mobility. This behavior is modeled using an effective salinity range and weighting function to gradually switch from high- to low-salinity relative permeability curves. There has been limited attention on physical transport of fluids during LSWF, particularly at large scale. We focus on how the salinity profile interacts with water fronts through the effective salinity range and dispersion to alter the transport behavior and change the flow velocities, particularly for the salinity profile.
We examined a numerical simulation of LSWF at the reservoir scale. Various representations of the effective salinity range and weighting function were also examined. The dispersion of salinity was compared with a theoretical form of numerical dispersion based on input parameters. We also compared salinity movement with the analytical solution of the conventional dispersion/advection equation.
From simulations we observed that salinity is dispersed as analytically predicted, although the advection velocity might be changed. In advection-dominated flow, the salinity profile moves at the speed of the injected water. However, as dispersion increases, the mixing zone falls under the influence of the faster-moving formation water and, thus, speeds up. To predict the salinity profile theoretically, we have modified the advection term of the analytical solution as a function of the formation- and injected-water velocities, Péclet number, and effective salinity range.
This important result enables prediction of the salinity transport by this newly derived modification of the analytical solution for 1D flow. We can understand the correction to the flow behavior and quantify it from the model input parameters. At the reservoir scale, we typically simulate flow on coarse grids, which introduces numerical dispersion or must include physical dispersion from underlying heterogeneity. Corrections to the equations can contribute to improving the precision of the coarse-scale models, and, more generally, the suggested form of the correction can also be used to calculate the movement of any solute that transports across an interface between two mobile fluids. We can also better understand the relative behaviors of passive tracers and those that are adsorbed.

Published: January 2019

Abstract
Unavailability of gas transmission network near a hydrocarbon discovery leading to high pipeline infrastructure development cost and can cause delays in production or remain stranded, for several small gas reservoirs. This study explores the avenues of exploiting small and stranded gas reservoirs, through virtual gas pipeline by compressing the gas and transporting it through bulk transportation modules, primarily for use at Captive Power Plants, Processing Industries and CNG Stations. Virtual Pipeline (VP) system is being effectively used in many parts of the world for production from low volume stranded gas reservoirs. In Pakistan, presently, three stranded gas reservoirs are producing about 4 MMscfd gas through VP system in the Northern region of the country with the first such system being operative since 2010. Whereas, several opportunities exist in the Southern region of the country, as well, to add production from stranded gas reservoirs to national energy network through VP system. An economic model has been developed for the operators to assess the viability of VP vis a vis gas transmission pipeline and bring low volume stranded gas into the system. Results of economic model indicate that for small stranded discoveries with uncertainties in connected hydrocarbon volumes, production through VP offers better NPV than the conventional pipelines. Based on economic model, the concept of VP was implemented at one of PPL’s well, which commenced production on 27 October 2017, and currently producing 1.4 MMscfd gas and 110 bbl/d of condensate. Based on the collected data, if higher hydrocarbon volumes in place are estimated, the feasibility of laying feeder line to a nearest processing facility may be re-evaluated to compare with the currently utilized VP system.

Abstract
Over the years, wireline formation testers have been frequently used for evaluation of near wellbore reservoir characteristics using mini-DST technique. Its primary applications are especially in case of tight or laminated layers where conventional testing approach is time consumingin terms of rig time and associated cost. Such evaluation helps client in optimizing their completion strategies. One such successful application of mini DST technique has been in Kandhkot field; which is sub divided into three domes having three reservoirs Sui Main Limestone (SML), Sui Upper Limestone (SUL) and Habib Rahi Limestone (HRL). Formation evaluation which included core analysis and open hole logs; was carried out in surrounding wells encountering SUL and it showed relatively less porosity and permeability in West dome (Φ=8-12% and K=0.1–1.68mD). Testing on two wells confirmed gas presence but its potential could not be established due to low rates. To address this challenge, wireline formation testing technique with straddle packers was opted in a well KDT X, encountering SUL formation. By successful utilization of Mini DST, Operator managed to evaluate critical reservoir parameters for characterization of all individual layers, which helped in better reserves estimates and reservoir modeling.
