An Efficient Numerical Hybrid Model for Multiphase Flow in Deformable Fractured-Shale Reservoirs
Authors: Yan Xia , Huang ZhaoQin , Yao Jun , Li Yang , Fan Dongyan , Sun Hai , Zhang Kai 
Published: June 2018

Summary
After hydraulic fracturing, a shale reservoir usually has multiscale fractures and becomes more stress-sensitive. In this work, an adaptive hybrid model is proposed to simulate hydromechanical coupling processes in such fractured-shale reservoirs during the production period (i.e., the hydraulic-fracturing process is not considered and cannot be simulated). In our hybrid model, the single-porosity model is applied in the region outside the stimulated reservoir volume (SRV), and the matrix and natural/induced fractures in the SRV region are modeled using a double-porosity model that can accurately simulate the matrix/fracture fluid exchange during the entire transient period. Meanwhile, the fluid flow in hydraulic fractures is modeled explicitly with the embedded-discrete-fracture model (EDFM), and a stabilized extended-finite-element-method (XFEM) formulation using the polynomial-pressure-projection (PPP) technique is applied to simulate mechanical processes. The developed stabilized XFEM formulation can avoid the displacement oscillation on hydraulic-fracture interfaces. Then a modified fixed-stress sequential-implicit method is applied to solve the hybrid model, in which mixed-space discretization [i.e., finite-volume method (FVM) for flow process and stabilized XFEM for geomechanics] is used. The robustness of the proposed model is demonstrated through several numerical examples. In conclusion, several key factors for gas exploitation are investigated, such as adsorption, Klinkenberg effect, capillary pressure, and fracture deformation. In this study, all the numerical examples are 2D, and the gravity effect is neglected in these simulations. In addition, we assume there is no oil phase in the shale reservoirs, thus the gas/water two-phase model is used to simulate the flow in these reservoirs.
Mexican-immigrant students transforming challenges into opportunities at a border school in the United States
Authors: Skukauskaitė Audra , Bolt Alicia 
Published: June 2018

As children of Mexican immigrant families enter schools in the United States of America, they face differences between their prior schooling experiences and the expectations in the new schools. Research on immigrant children has examined language and academic adaptation variables, yet little consideration has been given to the perspectives of children and their families and teachers. Utilizing principles of interactional ethnography, we examined elementary school student and their family and teacher perspectives about the differences between the children’s prior schooling in Mexico and their current experiences in an elementary school located in Ollin, a town in Texas, near the Mexico border.
Over the course of one academic year, we interviewed ten children, eight parents, and six teachers, conducted observations in schools on both sides of the border, and collected relevant documents to examine the larger social and educational contexts participants referenced in the interviews. Using an ethnographic perspective, discourse and contrastive analyses, and triangulation of sources and types of data, we focused on children’s perspectives to uncover the challenges they faced and the ways they overcame the challenges in their new, post-migration, school in Texas.
Children foregrounded two primary challenges: language and play time. However, we discovered that the children, their parents and teachers did not let the challenges stop their educational opportunities. Instead, despite the challenges, children, with support of peers, teachers, and parents, actively transformed the challenges and constructed new opportunities for learning and adapting to their post-immigration school. This paper demonstrates how focusing on children’s perspectives makes visible that children and immigrant families become active agents of change, transforming challenges into learning opportunities. In the ongoing deficit models of education and negative rhetoric about immigrants, the paper shows how the people themselves take ownership of their schooling and create social and educational welfare for themselves and others. Understanding immigrants’ active participation in their schooling has a potential to impact the ways other families, educators, and policy makers view and describe their own and others’ experiences of learning, schooling, and international migration.

Published: June 2018

Los acuerdos comerciales celebrados entre países permiten crecimiento en sus economías, de allí la importancia de tener en cuenta el desarrollo económico de cada país en juego en el momento de las negociaciones, así también el régimen jurídico que cada uno posee internamente para darle cabal cumplimiento al TLC suscrito. El presente artículo se desarrolla bajo una metodología deductiva, ya que las conclusiones son el resultado de las premisas planteadas, para el efecto se realizó una exhaustiva búsqueda de aquellas normativas internas presentes, tanto en Colombia como de Chile, para contrarrestar la presencia de cláusulas abusivas; éstas pueden ser tan lesivas en un tratado que son capaces de romper el equilibrio contractual que debe reinar en una negociación entre Estados negociadores. Por lo anterior, principalmente se concluirá en la necesidad de una normativa especial, para un control preventivo, que no solo advierta sobre la existencia de este tipo de clausulados y sus efectos, sino que reprima su estipulación siendo finalmente el legislador el llamado a ejercer ese control.

Published: June 2018

Resumo: Doença transmitida por alimento (DTA) é um termo aplicado a um conjunto de sintomas que possuem origens distintas e caracterizam um estado de adoecimento específico. A carne moída bovina, devido ao grande consumo entre a população brasileira, pode ser considerada um veículo de transmissão de infecções e/ou intoxicações alimentares ocasionadas por micro-organismos patogênicos. Tendo em vista essa importância, o objetivo deste trabalho foi analisar a contagem de aeróbios mesófilos na carne bovina moída comercializada no município de Palmas – PR, a fim de atestar as condições higiênico-sanitárias durante o seu processamento. A metodologia consistiu emum estudo quantitativo experimental. Foram analisadas amostras de carne moída bovina durante os meses de abril e maio de 2016 em cinco redes de supermercados da cidade de Palmas – PR, as quais foram denominadas A, B, C, D e E. A quantificação de micro-organismos em alimentos foi realizada através da contagem total de micro-organismos aeróbios mesófilos em placas, utilizando o meio de cultura Plate Count Agar (PCA). Realizou-se a leitura em 48 horas em placas com limite mínimo e máximo de 25 e 250 colônias. A média do número das colônias contadas nas placas em duplicata, multiplicada pelo fator de diluição das placas correspondentes, forneceu o número de micro-organismos mesófilos por grama da amostra analisada. Observou-se com os resultados alcançados que 60% das amostras apresentaram contagem na ordem de 104 UFC/g, porém o estabelecimento C apresentou 1,17 x 105 UFC/g, e o D com 2,06 x 106 UFC/g. Dessa forma, relacionado à qualidade microbiológica, as amostras analisadas encontram-se com elevadas populações de micro-organismos aeróbios mesófilos, constatando-se a necessidade do completo cozimento desse alimento, bem como a adoção das Boas Práticas de Fabricação por parte dos estabelecimentos comerciais.

Authors: Yang Yan-Tao , Zhu Jun-Fang , Liao Guochao , Xu Hai-Jiang , Yu Bin 
Published: June 2018

Background:
Antibiotic resistance is one of the biggest threats to global
health today, leading to higher medical costs and increased mortality. Because of the
emergence and rapid spread of new resistance mechanisms globally, a growing number of
infections are becoming harder to treat as the antibiotics used to treat them become less
effective. Therefore, the development of new effective antimicrobial agents is still urgently
needed. In last decades, a large number of structurally novel spirooxindoles have
been synthesized mainly based on the ylide intermediates generated in situ and further assessed
for their antimicrobial activity against different types of bacteria, leading to the discovery
of some potent lead compounds with antimicrobial potentials.

Objective:
The aim of this review to submarize recent advances on the synthesis, structure-
activity relationship studies (SARs) and antimicrobial activity of spirooxindoles.

Methods:
Peer-reviewed research work on spirooxindoles with antimicrobial activity were
downloaded from bibliographic databases and analyzed based on their chemoptypes.

Results:
50 papers were retrieved from the literature databases, of which 20 papers described
the synthesis and antimicrobial activity of spirooxindoles.

Conclusion:
This review highlights the importance of spirooxindoles as potential antimicrobial
agents. The antimicrobial activity of spirooxindoles against different types of bacteria
is less studied, mainly centering on primary antimicrobial assessment, some of these
compounds have showed interesting antimicrobial activity. However, the current study is
only limited to primary antimicrobial assessment, no detailed modes of action are investigated.

Published: June 2018

Introduction/ Methods:
The current study has compared the fluctuations of atmospheric precipitable water over Iran during three periods of 1948 – 1957, 1958 – 1978, and 1979 – 2012 using upper-air reanalyzed data from NCEP/NCAR.

Results:
The results indicated that, in all the three periods, average distribution and coefficient of spatial variation decreased with altitude. In contrast, there was a positive relationship between coefficient of spatial variation and altitude. The results of trend analysis showed that atmospheric precipitable water of Iran calculated using the upper-air reanalyzed data by NCEP/NCAR experienced various fluctuations during the three periods of 1948 – 1957, 1958 – 1978, and 1979 – 2012. The increase of the precipitable water during the first period was not significant at the level of 95%. The increase of the precipitable water during the second period was significant at the level of 95% just in 25% of the regions. In contrast to the second period, 70% of the country’s area followed a declining trend. However, this decreasing trend was not significant at the level of 95%, either.

Conclusion:
The results of Alexandersson statistical method showed that the biggest shift in the average of precipitable water happened during the third period. Overall, variations in the precipitable water over Iran in the past ~60 years are not within the uncertainty of the reanalysis data and are therefore clearly discernible.

Published: June 2018

Introduction:Dislocation of the radial head in adults is quite uncommon. A simultaneous dislocation of the radial head with a fracture of ipsilateral shaft radius without any other associated injury is even rare.Case Presentation:We are reporting a case of a young adult male who was operated for proximal one-third radial shaft fracture at some peripheral centre by Open Reduction and Internal Fixation (ORIF), but came to our centre on the fourth post-operative day with complaints of painful restricted movements of the elbow joint. On careful look at the postoperative x-ray, radial head was found to be dislocated. Radial head dislocation was reduced under general anesthesia and at 2 years follow up, patient fracture has fully united having good functional outcome.Conclusion:Traumatic dislocation of radial head with ipsilateral fracture shaft radius is a rare injury in adults and it is very important to timely diagnose it and manage it appropriately in order to give good functional outcome to the patient.

Agility in Audit: Could Scrum Improve the Audit Process?
Authors: Newmark Richard I. , Dickey Gabe , Wilcox William E. 
Published: June 2018

SUMMARY
Changes in environmental forces provide an opportunity for audit firms to move away from an up front and reactive audit planning approach to one that is more agile. Agility involves quicker adaption to the external and internal environments and can result in improved operating performance, quality, and client satisfaction. One way to introduce agility in a project-based organization is to adopt Scrum, an agile project management approach that has been applied in other industries to allow organizational teams to review, reflect, learn, and adapt. This “inspect-and-adapt” philosophy inherent in Scrum enables teams to effectively work in ever-changing conditions, resulting in a high level of sustainable productivity. We provide an overview of key Scrum principles and concepts and address future areas for Scrum research.
Experimental Study on Sedimentation Removal of Pervious Concrete
Authors: Rama M. , Shanthi V. M. 
Published: June 2018

Abstract Pervious concrete is a unique and effective material used to tackle important environmental problems, to maintain green, sustainable growth, and to reduce storm water runoff and pollutants. Clogging of pervious concrete is an important potential issue in serviceability, considered one of the primary limitations of pervious concrete systems. The sediment deposition pattern of pervious concrete was determined using three clogging materials: clay, sand, and clayey silty sand. The clogged specimens were cleaned by pressure washing, vacuuming, and a combined method. In total, ten clogging and cleaning cycles were carried out on each sample to evaluate the draining capacity of the pervious concrete. The clogging test was assessed by measuring the infiltration rate during clogging and after cleaning, for each cycle. The experiment results showed that a reduction in permeability due to different types of sedimentation material as well as recovery in permeability was achieved after applying various cleaning methods.
A Model of Interconnection Between Aircraft Equipment Failures and Aircraft “States” in Flight
Authors: Vaivads Andris , Tereščenko Jevgēnijs , Šestakovs Vladimirs 
Published: June 2018

Abstract
The article presents a semiotic model of “aircraft conditions” in flight and multilevel structures of an aircraft. The hierarchical structure of abstract models is divided into blocks and levels that make them more compact by applying a mathematical apparatus corresponding to the goals sated. The above models were tested on the basis of statistical data on TU-154 aircraft failures for 10 years. Various aircraft functional system failures in flight were examined. The state of the aircraft is identified by normative indicators recorded in the “Aircraft Technical Operation Manual”.
Evaluating the Use of Automated Feedback on Student Motivation
Authors: Simpson Leah , Jones Mikael , Taylor Stacy 
Published: June 2018

Objective: Autonomy-support and quality feedback have been shown to significantly impact student learning. Unfortunately, quality feedback is often very time consuming. The goal of this study was to examine the autonomy-supportive potential from feedback provided via technology, specifically the ExamSoft Strength and Opportunities report.
Methods: Students were divided into two groups: one received enhanced performance feedback via the ExamSoft Strength and Opportunities report, the other received traditional grade-only feedback in the form of grades and course averages, via ExamSoft. The Learning Self-Regulation Survey (SRQ-L) was administered to 139 third-year doctor of pharmacy students. The survey contained 14 statements asking students to rate their reasons (relative autonomy) for reviewing ExamSoft feedback, three items related to use of the ExamSoft technology, and five demographic items.
Results: A statistical difference, t(52) = -2.07, p =0.043; d = .577, was reported between the two groups indicating enhanced feedback via ExamSoft had a moderate impact on students’ autonomy.
Conclusions: Students who received enhanced ExamSoft feedback reported significantly higher relative autonomy index (RAI) for feedback review than students who did not receive the feedback. This suggests that the enhanced ExamSoft feedback was autonomy-supportive.

Authors: Vanjare Harshad Arvind , Panwar Jyoti 
Published: June 2018

Objective
The objective of the study was to assess the accuracy of ultrasound examination for the diagnosis of rotator cuff tear and tendinosis performed by a short experienced operator, compared to magnetic resonance imaging (MRI) results.

Method
A total of 70 subjects suspected to have rotator cuff tear or tendinosis and planned for shoulder MRI were included in the study. Shoulder ultrasound was performed either before or after the MRI scan on the same day. Ultrasound operator had a short experience in performing an ultrasound of the shoulder. Ultrasound findings were correlated to MRI findings.

Results
Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for the diagnosis of tendinosis were 58%, 84%, 63%, 80%, and 75%, respectively, and it was 68%, 91%, 73%, 88%, and 85%, respectively, for the diagnosis of rotator cuff tear.

Conclusions
Sensitivity for diagnosing rotator cuff tear or tendinosis was moderate but had a higher negative predictive value. Thus, the ultrasound operator with a short experience in performing shoulder ultrasound had moderate sensitivity in diagnosing tendinosis or tears; however, could exclude them with confidence.
