EXPANDED GRAPHITE AND NiFe2O4 FOR REMOVAL OF HEAVY OILS
Authors: Thinh Pham Van
Published: May 2018

The oil spill has severely caused environmental damage to ocean water resources resulting in significant negative influence on the ecosystem and putting the life of human at high risk. Hence, the development of efficient and low-cost adsorbents is an instrumental and essential task to purify oil-contaminated water. The corporation of magnetic particles into the adsorbents has recently considered as an innovative approach which facilitate phase separation under a magnetic field thus allowing easy and efficient recovery of the used adsorbents from polluted water in large scale. In this study, the expanded graphite (EG) and magnetic NiFe2O4 based composite prepared from available graphite source of Vietnam has been found as a potential adsorbent to remove crude oil (CO) and diesel oil (DO). The EG/NiFe2O4 was fabricated via a facile two-step process: (1) the expansion of graphite and (2) the decoration of magnetic NiFe2O4 on EG. The physical properties of as-obtained EG/NiFe2O4 were characterized by using Scanning Electron Microscope (SEM), Fourier-Transform Infrared Spectroscopy (FTIR), X-Ray Powder Diffraction (XRD), Vibrating-Sample Magnetometer (VSM) and nitrogen adsorption/desorption analysis. The effect of processing conditions including contact time, dosage of heavy oil and salinity of water on the adsorption capacity of the as-synthesized EG/NiFe2O4 composite for CO and DO was also investigated.

Authors: Nguyen Hoang Canh
Published: May 2018

In the study, raw materials including clinker, gypsum, pozzolan were separately milled on a ball mill (the ball mill size: φ500 mm × L500 mm, productivity: 5 kg / grinding time) to achieve the desired blaine fineness. A mixture is mixed at the calculated ratio includes of 90 % fineness clinker, 5 % fineness gypsum and 5 % fineness pozzolan (In it, pozzolanic additive is mixed at different fineness levels). The effects of the mixture of gypsum and fineness pozzolanic additive as well as the fineness of pozzolanic additive to strength of PCB50 Fico cement were investigated. The study shows that, pozzolanic additive have reduced the strength of cement. But, when pozzolanic additive is mixed with gypsum, this additive mixture has increased the strength of the cement at the late time (at the age of 28 days). The fineness of pozzolan has little effected on the early strength of cement.
A STUDY OF RED-EMITTING PHOSPHOR OF K2SiF6:Mn4+ FOR WARM WHITE LEDs
Authors: Anh Nguyen Le
Published: May 2018

This study focuses on the fabrication of red-emitting phosphor based on K2SiF6: Mn4+ phosphor. Characteristic emissive peaks in the red region of the Mn4+ ions involve the energy transfer from spin-forbidden states of 2Eg → 4A2, showing narrow band emission peaks at 609, 614, 631, 635 and 647 nm. Meanwhile, their absorptive peaks involve the energy transfer from spin-allowed states of 4A2 → 4Tg; the excited wavelength of the Mn4+ is in the range 360 - 460 nm. Thus, the K2SiF6: Mn4+ phosphor is particularly suitable for redundancy of 460 nm - Light Emitting Diode (LED); it complements the red emission of the commercial White LEDs.
FABRICATION AND PROPERTIES OF Co DOPED Bi0.5K0.5TiO3 – BiFeO3 SOLID SOLUTION
Authors: Tuan Nguyen Hoang
Published: May 2018

In this study, we present some results on the structure and properties of the solid solution of Bi0.5K0.5TiO3– BiFeCoO3 (BKT – BFCO) by Sol-gel method. Crystal structures of BKT – BFCO solid solutions were studies by XRD and Raman spectroscopy. The results were in good agreement with the previous reports of Bi0.5K0.5TiO3– BiFeO3 (BKT – BFO) and Bi0.5K0.5TiO3 – BiCoO3 (BKT – BCO) solid solutions. The magnetic properties were investigated via unsaturated M-H loop, which showed the competition of paramagnetic and antiferromagnetic ordering in BKT – BFCO. However, differing from the BKT – BFO and BKT – BCO solid solutions, the unclear values of saturated magnetism in BKT – BFCO raised the unexplained question, which needed further studies.
NEAR INFRARED – EMITTING Zn2SiO4 POWDERS PRODUCED BY HIGH-ENERGY PLANETARY BALL MILLING TECHNIQUE
Authors: Thao Vien Le Thi
Published: May 2018

The near infrared-emitting Zn2SiO4 powders were produced by high-energy planetary ball milling of ZnO and SiO2 powders followed by annealing in air environment and at different temperatures. The surface morphology, crystal structure, chemical composition and optical properties of the obtained samples were investigated by means of field emission scanning electron microscope (FESEM), X-ray diffraction (XRD), Raman spectroscopy and photoluminescence measurements (PL) at room temperature. The analysis indicates the formation of Zn2SiO4 phase with annealing temperature of 1250 oC.°C. The size of Zn2SiO4 nanoparticles depends strongly on annealing temperature. Photoluminescence investigation reveals that the optimal annealing temperature for almost only near-infrared emission (~740 nm) is 1250 oC. The origin of this peak can be attributed to the energy transfer from non-bridging oxygen hole centers (NBOHs) to zinc interstialinterstitial (Zni) and oxygen vacancy (Vo) states in the Zn2SiO4 host lattice. These results demonstrate that we might be able to produce the Zn2SiO4 powders for applications in high CRI white light emitting diodes by a simple and low-cost method.

Published: May 2018

Background

The purpose of this study was to review the risks and benefits of concurrent chemoradiation therapy (CCRT) with esophageal self-expandable metal stents (SEMS) for the treatment of locally advanced esophageal cancer.

Materials and Methods

Between January 2014 and December 2016, the data from 46 locally advanced esophageal cancer patients who received CCRT at our institution were retrospectively reviewed. Eight patients who received CCRT concomitant with SEMS placement (SEMS plus CCRT group) and thirty-eight patients who received CCRT without SEMS placement (CCRT group) were identified. The risk of developing esophageal fistula and the overall survival of the two groups were analyzed.

Results

The rate of esophageal fistula formation during or after CCRT was 87.5% in the SEMS plus CCRT group and 2.6% in the CCRT group. The median doses of radiotherapy in the SEMS plus CCRT group and the CCRT group were 47.5 Gy and 50 Gy, respectively. SEMS combined with CCRT was associated with a greater risk of esophageal fistula formation than CCRT alone (hazard ratio [HR], 72.30; 95% confidence interval [CI], 8.62–606.12; p < .001). The median overall survival times in the SEMS plus CCRT and CCRT groups were 6 months and 16 months, respectively. Overall survival was significantly worse in the SEMS plus CCRT group than in the CCRT group (HR, 5.72; 95% CI, 2.15–15.21; p < .001).

Conclusion

CCRT concomitant with SEMS for locally advanced esophageal cancer results in earlier life-threatening morbidity and a higher mortality rate than treatment with CCRT alone. Further prospective and randomized studies are warranted to confirm these observations.

Implications for Practice

Patients treated with SEMS placement followed by CCRT had higher risk of esophageal fistula formation and inferior overall survival rate compared with patients treated with CCRT alone. SEMS placement should be performed cautiously in patients who are scheduled to receive CCRT with curative intent.
Closely spaced rectangular footings on sand over soft clay with geogrid at the interface
Authors: Saha Roy S. , Deb K.
Published: May 2018

In this study, laboratory-scale experiments are carried out to investigate the interference effect on bearing capacity and settlement behaviour of two closely spaced identical footings placed on the surface of a sand layer of limited thickness underlain by a soft clay layer with geogrid at the interface. Three pairs of model footings of different sizes are used in the study. The width (B) and length (L) of the footings are chosen in such a way that the L/B ratio (aspect ratio) of the footings is varied as 1.0 (square), 1.5 (rectangular) and 2.0 (rectangular). It has been observed that there is an optimum spacing where the bearing capacity of the interfering footing reaches the maximum value. The optimum spacing is found to be 2.0 times the width of the footing for all shapes of footings at H/B = 0.75, where H is the thickness of sand over soft clay. The maximum interference factor for bearing capacity (for a square footing) in homogeneous reinforced sand is 18% more than the sand-clay layered soil. The influence of footing interference increases with an increase in L/B ratio. The strain distribution along the reinforcement is also investigated and it is found that the strains in the reinforcement vary with the spacing ratio.
A combined split-spoon sampler and spherical penetrometer: laboratory trials
Authors: Mishra S. , Robinson R. G.
Published: May 2018

Full flow penetrometers (FFPs) such as T-bar and ball penetrometer provide reliable estimates of undrained shear strength (su) of soft-soil deposits. Several studies are reported in the literature on the field application of these penetrometers for offshore applications typically for the deep-water environment. However, the lack of sampling provision creates problem for identifying the accurate soil type from the load–penetration response. Information obtained from the field samples is vital in determining the stratigraphy and conducting several basic laboratory tests. This study proposes a new sampling-cum-penetration testing device, which uses a split-spoon sampler for sampling with a spherical cutting shoe. The cutting shoe was modified to increase the bearing area for enhanced accuracy in soft deposits. Strength assessment study was conducted in the laboratory using remoulded kaolin clay at various undrained shear strengths. To investigate the occurrence of plugging and the extent of influence zone during penetration, image-based deformation measurement technique was adopted. The modified ball penetrometer shows a strength factor of about 14·3 in remoulded kaolin clay.

Authors: Miri Fatemeh , Azizi Danial Babajani
Published: May 2018

The present study made an attempt to determine the effect of teaching critical thinking skills on Iranian EFL learners' essay writing ability. To do this, a sample of 60 EFL learners was selected based on their performance on Preliminary English Test (PET). The participants were randomly assigned to two equal groups of control and experimental. An essay-writing test functioning as pre-test was administered on both groups in order to ensure their homogeneity in terms of writing ability. The groups received 10 sessions of writing instruction; however, experimental group received additional instruction and practice regarding the techniques of critical thinking. Finally, both groups took an essay writing posttest in order to compare their writing achievements. Both pretest and posttest were scored by two raters using TOEFL rating scales. The results of paired and independent sample t-tests showed that critical thinking techniques significantly enhanced EFL learners writing ability.
A Cross-cultural Comparative Analysis of Sino-American Family Conflicts Management
Authors: Xue Ziyi , Lu Jingjing
Published: May 2018

Based on Culture Dimension Theory, the author explores the dynamic factors causing family conflicts by observing and analyzing the behaviors in the episodes of the sitcoms Modern Family and Home with Kids. This paper attempts to answer two basic research questions: How do Chinese and American people deal with family conflicts? Is there any similarity or difference in the family conflicts of the two cultures? The paper compares the Sino-American family conflicts in three aspects: the cultural value context and the cultural reason leading to the conflicts; the conflict management styles being resorted to by the two families; and the changes and new findings in the conflict management strategies of two families. Through the comparative analysis on family conflict from two cultural contexts, the author is not only going to address the similarities and differences in family conflicts and conflict management strategies in those two cultures, but to explore whether different behaviors are driven by different cultures and values or not. Furthermore, through this cross-cultural comparative analysis, it would be helpful to understand globalization and integration and to avoid misunderstandings or conflicts in intercultural communication.
A Review of Language Learning Strategy Research
Authors: Su Yanfei
Published: May 2018

Language learning strategy, a crucial variable of individual differences in second language acquisition (SLA), has been a fiercely discussed topic since 1970s, attracting a large number of researchers and teachers who have already made great achievements. This article aims to conduct a small-scale review of studies concerning language learning strategy, finding that studies in this respect were done mainly from perspectives of definition, identification and classification, usage and assessment and instruction of language learning strategy, and factors which exert influences on it. It is plausible to say that research on this issue is comparatively comprehensive, appreciating wide coverage and great achievements, but certain points are still in controversy. Although there are many related studies, rare studies were devoted to language learning strategy under the context of learners in mainland China. Subsequently, implications for further research and pedagogy in terms of language learning strategy are discussed.
Multicultural Communication Competence and Education in Ethnic Minority Areas of Yunnan
Authors: Li Hao
Published: May 2018

Cultural diversity is evident throughout schools in border provinces of China, especially in Yunnan, which has the largest number of ethnic minorities. To what extent do teachers in Yunnan prepare their teaching to cater for the needs of culturally and linguistically diverse students? Findings revealed that cultural and communicative barriers exist in Yunnan's schools, resulting in the academic underachievement of minority students. This paper integrates some external issues, such as the insufficient family education and a lack of support and understanding from schools, with internal problems, such as students' and teachers' scant knowledge in multicultural communication and the stress from psychological and behavioural adjustment during the acculturation process, into a summary as multicultural communicative and educational problems. To solve these problems, theories and practice of multicultural communication competence are introduced to meet the varied needs of students in the multicultural environment, and integrate teachers with theoretical approaches for multicultural communication education. School courses need to be updated to address the needs of students from different cultural backgrounds, and this paper also provides practical ways to begin with.

A reforma do ensino superior no contexto da reforma do estado brasileiro
Authors: Brandim Maria Rejane Lima , Feldmann Marina Graziela
Published: May 2018

A Reforma do Estado brasileiro estabelecida nos anos 90 do século XX durante o governo de Fernando Henrique Cardoso (1995-2002) é o ápice da ascensão das políticas neoliberais no país, representadas pelo forte ajuste fiscal e a implantação de um Estado mínimo, conformando o estabelecimento de diminuição ou corte nos gastos públicos e a progressiva privatização de empresas estatais e de serviços públicos de uma maneira geral.  Esta reforma, configura-se como a primeira geração de reformas neoliberais brasileiras que buscam, especificamente, a redefinição do estado e do que lhe é atividade exclusiva e do que será considerado seu corpo de servidores.A segunda geração de reformas acontece nos anos do governo de Lula da Silva (2003-2010), numa expressiva complementaridade ás reformas iniciadas no governo anterior, ainda que estas se mostrem contrárias às necessidades dos trabalhadores brasileiros em geral e fortemente marcadas pelas diretrizes dos organismos internacionais do capital tais como o Banco Mundial e o Fundo Monetário Internacional, para os chamados países periféricos.  Entre os anos de 2003 e 2007, no contexto da Reforma do Estado, passou então a ser institucionalizada a reforma do ensino superior brasileiro, que ganha corpo com a adoção de um conjunto de medidas, dentre elas, o Programa de Apoio aos Planos de Reestruturação e Expansão das Universidades Federais (REUNI), implantado por Decreto lei em 2007. Propomo-nos a analisar, a partir de uma pesquisa bibliográfica, a política de expansão do ensino superior brasileiro efetivada no contexto da reforma do estado e as transformações educacionais determinadas por essa política, implantadas nas instituições publicas de ensino superior no período de 2007-2012. Buscamos identificar nessa expansão, a configuração de um processo efetivo de democratização  do acesso ao ensino superior no Brasil. Nossos estudos, até o momento, apontam para um aumento significativo de instituições federais criadas no periodo, para o  aumento das matrículas, para a expansão de campi, para o aumento na contratação de docentes. Contudo, identificamos problemas na implantação do REUNI, no que diz respeito principalmente à estrutura física com novas Universidades e Campi de Expansão em processo de construção;  à estrutura pedagógica e curricular, com novos cursos criados cujos Projetos pedagógicos encontravam-se em fase de elaboração; ao trabalho docente precarizado pela sobrecarga de disciplinas e o acúmulo de outras atividades afins ao exercício do magistério superior.

Background and Purpose:

The purpose of this study was to psychometrically analyze the Caffrey Cultural Competence in Healthcare Scale (CCCHS), a scale that measures self-assessed cultural competency of nursing students participating in international immersion experiences during their nursing curriculum.

Methods:

A sample of 105 health professions students completed the CCCHS. Inter-item correlations, exploratory factor analysis (EFA), and Cronbach’s α were used to examine validity and reliability. Results: Results indicated that items were positively related. A 1-factor model of the CCCHS was found in which all items loaded onto a single factor at ≥ .30, except two items dealing with national policy, which may not be a component of cultural competence.

Conclusion:

The CCCHS was internally consistent (α = .93) and is a valid and reliable scale consisting of a unidimensional factor.

The aim of this study was to understand and describe the experience of diabetes self-management among patients not meeting glycemic control (A1C > 9). Type 2 diabetes mellitus (T2DM) is a complex chronic disease process. Diabetes self-management is equally complex and critical to patient outcomes and quality of life. The components for self-management include: knowledge, skills/abilities, and support. Few studies have reported on the experiences of self-management for patients with T2DM to reach and sustain glycemic control. This study used a qualitative descriptive design. Semistructured interviews were conducted with 13 patients receiving care at a diabetic clinic at a major health-care system in New York City. An interview guide was developed based on diabetes self-management which guided the interviews. All data were analyzed using qualitative content analysis. Initially, three themes that describe each component of diabetes mellitus self-management (DMSM) and impact the patients’ reaching the desired outcome were identified: acceptance of knowledge, motivation for skills and abilities, and variability and vulnerability of support. Further analysis of the three themes led to the identification of an overarching, theme: loss of self. This overarching theme helped to explain the stages of grief illustrated across the themes in the participants DMSM experiences. The participants in this study identified loss of self, and the accompanying grief and grieving process related to the loss of self in response to their T2DM diagnosis. Participants were “stuck” in a stage of loss of self, which presented challenges to acceptance of their diagnosis, barriers to DMSM, and optimizing glycemic control.
Interprofessional Collaboration With Pharmacist-Driven Education for Hypertension Control in Federally Qualified Health Center Patients

Published: May 2018

Introduction:

Providing collaborative care is essential to decrease cardiovascular complications of hypertension (HTN). Care coordination models, including the Patient Centered Medical Home (PCMH), are advocated to manage chronic diseases. However, they offer no guidance on collaborative strategies to improve patient outcomes. This project enhanced the PCMH model at a Federally Qualified Health Center (FQHC) through application of interprofessional collaboration (IPC) concepts including role optimization, shared decision making, shared power, and care expertise.

Methods:

Application of IPC concepts with the key addition of a pharmacist education component was instituted at a Midwestern FQHC over a 60-day period with a single care team. Inclusion criteria included adult patients with a diagnosis of uncontrolled primary HTN (>140/90). Blood pressure, perception of IPC, and patient and care team satisfaction were measured. Descriptive statistics, paired t-test, and unpaired t-test were used for analysis.

Results:

Twenty-two patients participated in the process change. Mean BP demonstrated a statistically significant decline. Care team perception of IPC improved. Care team members and patients reported satisfaction with the overall process change.

Conclusion:

This project offers support to increase knowledge of how IPC competencies and concepts can be incorporated into an FQHC and the effect it may have on hypertensive patients being treated under a PCMH model.

A very dynamic environment and constant technological advances are surrounding small and medium-sized enterprises (SMEs) in their commercial activities. The business context is becoming increasingly complex, as there are continually numerous aspects related to the application of knowledge, both financial, legal, organizacional and technological. In relation to the application of information and communication technologies (ICT), SMEs need to acquire and apply knowledge correctly to obtain the best use of these technologies in their business processes. Taking this scenario into account, the objective of this paper is to present the case study on the application of a conceptual model based on knowledge management (KM) to improve the level of use of ICT in the business processes of mexican SMEs. The model was applied in an SME of the commercial sector. The results obtained are exposed, as well as the conclusions and future perspectives of the work developed.
Título Superior De Música. Relación Entre La Motivación De Logro Musical Y Las Conductas Desadaptativas De Abandono En Estudiantes
Authors: Zarza-Alzugaray Francisco Javier
Published: May 2018

The motivation of musical achievement is one of the main requirements to achieve academic success during the formative period of the students (Zarza, 2014). In this sense, behaviors such as the consumption of substances or cognitions such as thoughts of dropping out of musical studies are usually very present in music students and generate long-term maladaptive behavior sustained over time that can prevent a correct musical training or even the actual abandonment of them. We present a first approach to the relationship between motivation and substance use, as well as the presence of thoughts of abandonment. In this sense, an improvement is proposed in the training plans that tend to a greater individualization and surveillance of the presence of this type of behavior linked with low motivational levels.

Las autoridades económicas y los responsables de la política social en los países latinoamericanos han venido haciendo esfuerzos para mejorar las condicionesde vida de la población, mediante la generación de una renta per cápita sostenida, que conduzca a mejorar los indicadores de desarrollo económico y a reducir los niveles de pobreza de la región. Este documento evidencia, por medio de la metodologíade la estadística descriptiva, que las principales variables de desarrollo económico están influenciadas por el PIB per cápita en Argentina, Bolivia, Brasil,Chile, Colombia, Costa Rica, Ecuador, El Salvador, México y Perú. De acuerdo a la evidencia empíricase puede concluir que Argentina es el país que más inversión realiza en educación, seguridad social ysalud, debido a que sus tasas de crecimiento económico han sido estables en un lapso considerable, mientras que Bolivia es el país que registra la menor inversión pública social, explicado por su bajo desempeño económico.
Gestión ambiental de los servicios públicos domiciliarios: seguimiento para el departamento de Cundinamarca
Authors: Usaquén Chía Martha Inés
Published: May 2018

Este artículo presenta el estado actual del sector de servicios públicos domiciliarios del departamento de Cundinamarca, teniendo en cuenta únicamente acueducto, alcantarillado y manejo de residuos sólidos, considerados determinantes de la calidad de vida de la población, vistos principalmente a partir de parámetros como cobertura e inversión en la prestación de estos servicios. Se toma como referente teórico la Nueva Economía Institucional, considerando que son las instituciones las que pueden aportar al cambio en beneficio del sector; el marco regulatorio lo establece la Constitución Política de 1991, la Ley 142 de 1994 para el control social y administrativo de los servicios públicos domiciliarios (SSPPDD), la Ley 143 de 1994 de procedimientos básicos desde la recolección hasta la disposición final de los desechos, entre otros. Se concluye que es determinante involucrar a todos los estamentos de la sociedad en la solución del problema de la prestación de los SSPPDD referidos, por ejemplo, mediante la conformación de los Comités de Desarrollo y Control Social, que permitan organizar la participación comunitaria para la vigilancia y la fiscalización de la gestión de las empresas que presten el servicio, sean de carácter privado, oficial o mixto, así como los Fondos de Solidaridad y Redistribución de ingresos en el caso de los Acueductos Municipales.

Are Markets Truly Efficient? Experiments using Deep Learning for Market Movement Prediction
Authors: Das Sanjiv , Mokashi Karthik , Culkin Robbie
Published: May 2018

We examine the use of deep learning (neural networks) to predict the movement of the S&P 500 Index using past returns of all the stocks in the index. Our analysis finds that the future direction of the S&P 500 index can be weakly predicted by the prior movements of the underlying stocks in the index. Decomposition of the prediction error indicates that most of the lack of predictability comes from randomness and only a little from nonstationarity. We believe this is the first test of S&P500 market efficiency that uses a very large information set, and it extends the domain of weak-form market efficiency tests.
Densidad mineral ósea en niños celiacos. Indicaciones de estudio y efecto de la exclusión del gluten de la dieta
Authors: Jorquera Plaza Francisco
Published: May 2018

Introducción:Una de sus principales manifestaciones extradigestivas de la enfermedad celiaca es la disminución de la densidad mineral ósea (DMO). La densitometría ósea realizada con DXA es el método de elección para la valoración de la DMO. Las indicaciones de su uso en niños celiacos son controvertidas.Objetivos:Analizar la DMO y diversas variables clínico-analíticas en niños celiacos cuando son diagnosticados y tras realizar una dieta sin gluten. Definir un perfil de pacientes con mayor probabilidad de presentar afectación de la DMO en base a diversas características individuales, para realizar indicaciones de DXA.Métodos:Estudio realizado 24 niños celiacos (12 varones) (Edad: 8,7±3,3 años). Mediante DXA se determinó su DMO al diagnóstico y tras realizar dieta sin gluten. La DMO fue comparada en cada paciente en los dos momentos del estudio y al diagnóstico entre grupos de pacientes estratificados según criterios de gravedad dependientes de variables clínicas, analíticas e histológicas. Resultados: La DMO fue normal en todos los pacientes estudiados en el momento del diagnóstico y tras realizar tratamiento, sin apreciarse diferencias entre esos dos momentos del análisis. Los niños que presentaban sintomatología cuando eran diagnosticados de enfermedad celiaca tuvieron menor DMO en columna y fémur que los asintomáticos. La calcemia tuvo correlación inversa con el tiempo de evolución de la enfermedad antes de su diagnóstico.Conclusiones:En general, en nuestro medio, no está indicada la realización de estudio de la mineralización ósea en los niños celiacos, salvo cuando haya existido una evolución clínica prolongada antes del diagnóstico.
