La nación en la televisión informativa Colombiana: 1960 y 2015. Del infractor inexistente al enemigo omnipresente
Authors: Narvaez Montoya Ancizar , Romero Peña Ana Carmenza
Published: July 2017

El artículo expone un adelanto de los resultados del proyecto Educación mediática y nación en Colombia: la narración y la institucionalización ‘audiovisual’. Se trata de diferenciar entre la manera como se narra la nación en los noticieros televisivos colombianos de los años sesenta (Actualidad panamericana) y la manera como se narra en los de hoy (Noticias rcn). Para ello, se analiza la narración mediática de la nación en los informativos televisivos de los años sesenta y en los actuales, desde cuatro aspectos contemplados por la teoría de los códigos: sustancias expresivas, formas expresivas, formas de contenido y sustancias de contenido. De estos aspectos, solo se expone aquí lo relacionado con la sustancia del contenido. Se establece una comparación entre las formas de representar, pero sobre todo entre lo representado como nación, en la televisión informativa en dos momentos de su desarrollo separados por más de 50 años.
Cortometrajes ambientales utilizados como herramientas para construir cultura ambiental en estudiantes de bachillerato
Authors: Becerra Niño Ángela Marcela
Published: July 2017

Este trabajo muestra una experiencia basada en la aplicación del proyecto de aula, en el cual se observó que los estudiantes del colegio Instituto Integrado de Comercio de Barbosa, Santander, tienen muy poca cultura sobre el cuidado del ambiente, pues se evidencia una mala actitud frente al respeto por la biodiversidad presente en la planta física de su institución. Por tal razón, se trabajó con herramientas pedagógicas como los cortometrajes ambientales para construir una cultura ambiental, pretendiendo que los estudiantes se concienciaran sobre los problemas que afectan día a día el bienestar de la madre tierra y lleven a cabo pequeñas acciones como el ahorro de agua, botar la basura en su lugar, ayudar a cuidar y valorar la fauna y flora presente en su colegio y, sobre todo, que transmitan dichas acciones a sus compañeros y sus familiares. Esta herramienta fue de gran utilidad, pues no se empleó mucho tiempo e hizo que los estudiantes, de una forma divertida, reconocieran muchos de los problemas ambientales que surgen hoy día, como la deforestación, la contaminación, el calentamiento global, etc., y eso permitió que al finalizar las presentaciones de los cortos, entablaran discusiones sobre sus acciones, para que puedan transformar positivamente sus estilos de vida y aportar de esa manera a un ambiente sano para las generaciones venideras.

Bioprinting of osteochondral tissues: A perspective on current gaps and future trends
Authors: Datta Pallab , Dhawan Aman , Yu Yin , Hayes Dan , Gudapati Hemanth , T. Ozbolat Ibrahim
Published: July 2017

Osteochondral tissue regeneration has remained a critical challenge in orthopaedic surgery, especially due to complications of arthritic degeneration arising out of mechanical dislocations of joints. The common gold standard of autografting has several limitations in presenting tissue engineering strategies to solve the unmet clinical need. However, due to the complexity of joint anatomy, and tissue heterogeneity at the interface, the conventional tissue engineering strategies have certain limitations. The advent of bioprinting has now provided new opportunities for osteochondral tissue engineering. Bioprinting can uniquely mimic the heterogeneous cellular composition and anisotropic extra-cellular matrix (ECM) organization, while allowing for targeted gene delivery to achieve heterotypic differentiation. In this perspective, we discuss the current advances made towards bioprinting of composite osteochondral tissues and present an account of challenges—in terms of tissue integration, long-term survival, and mechanical strength at the time of implantation—required to be addressed for effective clinical translation of bioprinted tissues. Finally, we highlight some of the future trends related to osteochondral bioprinting with the hope of in-clinical translation.
Book review – Standards, quality control, and measurement sciences in 3D printing and additive manufacturing
Authors: Tran Tuan
Published: July 2017

There is a gap between 3D printing’s fast pace of development and the acceptance of 3D printing technologies by other industries and applications. This hesitation comes mostly from unanswered questions about the consistency, reproducibility, and quality of 3D-printed products. Although the list of excellent examples demonstrating its potential keeps expanding, a wide and thorough adoption of the technology requires crucial, yet currently missing elements including consensus standards, quality control procedures, and measuring methodologies. Progress in developing these elements, however, has been rather limited.
Finding God in All Things: Identity and Purpose in a Jesuit Community for the Elderly
Authors: Odean Jon-Michael
Published: July 2017

This article is an investigation into the development and maintenance of identity of elderly Jesuits residing in the Jesuit Community for the Elderly (JCE) in Maryland. Through qualitative research and analysis using identity theory, I investigate the human creature as an embodied being oriented to perceive and respond to meaning, and to construct identity out of the process. I look to see the means by which these individuals, especially in the context of a religious order and old age, create and maintain their identities. I conclude that with the intentional practice and construction of foundational habits in the context of community, the residents of the JCE, no matter their state of physical deterioration at this late stage in the life cycle, are able to maintain their identity as Jesuits, continue relational practice through ministry, and maintain a profound sense of meaning in life.

Formed in the Image of God: The Theological Status of Neanderthals
Authors: Stueve Megan
Published: July 2017

A thorough examination of the various theological interpretations of imago Dei shows that Homo sapiens are not the only species to be created in the image of God.  While maintaining their uniqueness in the eyes of the Lord, Homo sapiens also share this gift with another species, Homo neanderthalensis.  The archaeological record proves that Neanderthals qualify for imago Dei under each of the four main interpretations of the biblical term.   Based on their rationality and adaptive nature, their compassion through use of medicine, their social networking and their symbolic use of art, it can be concluded that Neanderthals were also created in God’s image.

'I was born in the reign …': Historical orientation in Ugandan students' national narratives
Authors: Holmberg Ulrik
Published: July 2017

In 2012, Uganda celebrated 50 years as an independent state following more than half a century under colonial rule. Since independence, Uganda has experienced a period of political turmoil and civil war within its constructed colonial borders. Given these historical experiences, what
do students find important about their nation's history and what history do they relate to when asked to explain their contemporary society and envisage possible futures? This article argues that Ugandan students' historical orientation is informed by and dependent on these students' local
contexts. Furthermore, those students adopting a retrospective approach to history, compared with those applying a prospective approach, made more sophisticated judgements about the past. The study on which this article is based explores 219 narratives written by 73 Ugandan upper secondary
students. The narratives were elicited through written responses to three assignments and were designed to capture different approaches to history, specifically prospective and retrospective approaches. Participants originated from two distinct regions: central and northern Uganda.
The empirical results show how different approaches to history influence the students' narratives. For instance, value judgements about past developments were more common among students applying a retrospective approach. Students from northern Uganda were generally more inclined to
tell a story of decline.
Flemish students' historical reference knowledge and narratives of the Belgian national past at the end of secondary education
Authors: Van Havere Timo , Wils Kaat , Depaepe Fien , Verschaffel Lieven , Van Nieuwenhuyse Karel
Published: July 2017

Since the early nineteenth century, western governments have expected history education to play a vital role in the formation of a national identity and the pursuit of national cohesion, by fostering shared knowledge and a shared (master)narrative of the national past. This article
reports on a qualitative study that examines which narratives young adults construct about their national past, to what extent those narratives are underpinned by existing narrative templates, whether they reflect on the fact that the national past can be narrated in different ways, and to
what extent they share a common reference knowledge. The study addresses the Flemish region of Belgium, a case characterized by a specific context of a nation state in decline, wherein diverse and often conflicting historical narratives coexist in popular historical culture and where the national
past is almost absent from history education. A total of 107 first-year undergraduate history students were asked to write an essay on how they saw the national past. The influence of both history education and popular historical culture was reflected in the reference knowledge as well as
in the (absence of) templates that students used to build their essays. Templates were not critically deconstructed, although some students nevertheless were able to discern and criticize existing 'myths' in the national past.
Educational leadership on the Chinese mainland: A case study of two secondary schools in Beijing
Authors: Lai Manhong , Wang Lijia , Shen Wei
Published: July 2017

In recent years, the main concern of the Chinese Ministry of Education has been the quality of education. Principals are expected to play a key role in guiding the developmental direction of their schools, in guaranteeing the implementation of curriculum reform and in facilitating school-based
teacher development. The aim of the study referred to in this article was to investigate the characteristics of principals' educational leadership through a case study of two secondary schools in Beijing. The study employed a qualitative research method to investigate educational leadership
in two secondary schools in Beijing. The observations of our study indicate a strong tendency for principals to implement the traditional top-down instructional type of leadership promoted by the District Education Bureau. At one of our sample schools, the principal employed a paternalistic
leadership style, and teachers at both schools emphasized the paternalistic role of the principal, including in engaging in various aspects of their personal lives. At our second sample school, the principal was attempting to delegate certain levels of authority and responsibility to ordinary
teachers. However, we found that her efforts were being hindered by middle managers.
Reclaiming Filipino America through Performance and Film
Authors: De Lara Marlo Jessica
Published: July 2017

Filipino Americans are the fourth largest migrant group in America and the second largest Asian population in the United States. Migration from the Philippines is constant and has increased dramatically in the last sixty years. Filipino Americans participate as the ‘Asian American’ identity/race but the specificity of Philippine-U.S. relations and migration pathways make this inclusion a misfit. As a former territory and with complex shifting migration policies, Filipinos have been considered by the U.S. government an ambiguous population, falling just out of reach of national visibility. As the population has continued to grow, Filipino Americans have shared narratives and begun conversation to address the constant cultural negotiation and struggles within the social and racial structures of America. Since the 1980s, a Filipino American cultural and artistic movement or ‘moment’, has emerged with artists, dancers, performers, and filmmakers. These artists make critical interventions that disavow the American empire. The works make comment upon the ramifications of being an unrecognized Asian colony and the systemic challenges of immigration assimilation. An example of a work from this cultural moment is Jose Antonio Vargas’ autobiographical documentary Documented (2013). The film, intended as an up close and personal account of an undocumented migrant in the United States, also serves as an example of current Filipino American cultural productivity and visibilization. By studying this artistic movement, one can approach deeper understandings of citizenship and national belonging(s) in the current transnational climate and the border crossings that circumscribe the Filipino American diaspora.

121Germanistik in Maribor: Tradition und Perspektiven
Authors: Jesenšek Vida
Published: July 2017

Tradition and perspectivesIn 2015 the Department of German Studies at the Faculty of Arts, University of Maribor, celebrated its 50th anniversary. On April 16, 2015 we commemorated this anniversary with a festive event, at which the professors and students of the department aswell as invited guest lecturers presented diverse views on German Studies as an academic and scientific discipline in modern times aswell as ponder about the past, present and future of learning and teaching German as a foreign language. Apart from this festive meeting we also prepared a retrospective exhibition about the history and thematic diversity of German Studies at the University of Maribor and organized a summer school entitled Alltag regional, which took place between June 29th and July 10th, 2015. The jubilee monograph, dedicated to the 50th anniversary of German Philology at the University of Maribor, brings reflection on the past, present and future of German Studies, on the theory and practice of German philology at universities outside of German speaking countries, but it also includes scientific articles from various fields of German linguistics, German literary science and the Didactics of German as a foreign language. The authors of the articles are staff members and students of the Department of German Studies at the Faculty of Arts, University of Maribor and colleagues from abroad. The monograph is divided into two parts: the first part offers a critical analytical view of the impact of the Bologna process on German Studies programs and the status of German Studies in university education; it contains six articles in which the authors write about the European tradition and future perspectives, the student experiences and ponder about the meaning and sense aswell as the integration of German Studies programs in the environment. The second part contains scientific articles from various fields of modern German Studies. The articles are ordered alphabetically by the names of the authors and they tackle lexicographical, methodical-didactic, stylistical, paremiological, sociolinguistic, morphological and word formation issues, discussđ the modern higher education policy and analyze selected German literary texts. The jubilee monograph offers an insight into the varied and changing 50-year-history of German Studies in Maribor and bears witness to the broad spectrum of the contemporary research in the field of German language and literature at the University of Maribor and elsewhere.
Evolución de la competitividad de las entidades federativas mexicanas en el siglo XXI. ¿Quién gana o pierde?
Authors: Unger Kurt
Published: July 2017

Antecedentes: En este artículo retomo el análisis de la competitividad económica de las 32 entidades del país para el 2013, mismo que antes se había hecho con los Censos Económicos 2003 y 2008. Método: Tomamos las 81 actividades que representan poco más de 96% de la actividad del país en 2013 y se calcula la competitividad con base en dos dimensiones: la productividad laboral y los salarios. Mediante la técnica de análisis de cluster dicotómico se hace la distinción entre estados competitivos y no competitivos. Resultados: El principal resultado es que se conservan los dos tipos de entidades antes vistas en el 2008 en cuanto a condiciones de competitividad, pero integrando dos nuevas entidades. Ahora las 13 entidades más competitivas cuentan con una economía más productiva, más diversificada y con mayores niveles de productividad y salarios. Se trata de entidades económicamente más maduras como Nuevo León, la Ciudad de México, Querétaro, el Estado de México, Jalisco, Guanajuato y San Luis Potosí, y los estados de la frontera norte. Los otros 19 estados con atraso relativo intentan compensar la falta de productividad con el castigo a los salarios. La condición más crítica se observa en estados del sursureste y otros de la costa Pacífico. Conclusiones: La conclusión principal es que, a pesar del alcance al grupo competitivo por estados del Bajío como Guanajuato y San Luis Potosí, la convergencia entre entidades no se dará por mero tránsito del tiempo.
Can Austin Chalk Expansion Lead to Revival?
Authors: Parshall Joel
Published: July 2017

Interest is growing in drilling the Austin Chalk formation, with oil and gas companies hopeful that applying the latest unconventional resource development technologies can open a new chapter of expansion in a historically prolific play that dates to the 1920s.

Much of the new drilling is in areas of the Chalk that overlie some of the most active parts of the Eagle Ford Shale play in south Texas. Drillers there are taking advantage of the additional stacked play opportunities that can often be drilled with the same rigs and crews they are using in the Eagle Ford and sometimes in the same well. Some operators may have also drilled in the Chalk during the depths of the industry downturn to hold leases and temporarily defer deeper Eagle Ford wells.

The Austin Chalk extends from Mexico across south and east Texas and a large portion of Louisiana to Mississippi. The history of the Chalk play has seen several booms, the last one coming in the 1990s with the introduction of horizontal drilling. Cumulatively, the formation has produced 1.7 billion BOE with approximately 9,500 wells having been drilled there.

Abundant Resources

There is good reason to believe that abundant oil and gas resources remain in the Austin Chalk. The United States Geological Survey released a study of four Austin Chalk-area assessment units (AUs) in 2010 that estimated mean undiscovered resources for the Austin Pearsall-Giddings AU of 879 million bbl of oil, 1.3 Tcf of gas, and 106 million bbl of natural gas liquids (NGLs). Three other AUs were estimated to hold a combined mean 78 million bbl of oil, 2.3 Tcf of gas, and 257 million bbl of NGLs.

Among the most active participants in the latest Austin Chalk play have been EnerVest, EOG Resources, Encana, and Murphy. Other companies active in the Chalk include GulfTex Energy, ConocoPhillips, Devon Energy, Marathon, Abraxas Petroleum, and Chesapeake.

EnerVest, which acquires, develops, and operates oil and gas fields on behalf of its institutional investors, is the largest producer in the Austin Chalk. The company built a substantial position there beginning with its 2007 acquisition of Anadarko’s holdings in Texas’ Giddings field, which has been producing since the 1930s. EnerVest’s move into the Chalk came years before most other current players.

In the Giddings field, as in certain other parts of the Austin Chalk, the formation lies above the Eagle Ford. But Eagle Ford development has been minimal there, compared with core Eagle Ford activity taking place from 20 to 80 miles southwest of the field.
Chemical EOR - A Multidisciplinary Effort to Maximize Value
Authors: Jürgenson Gabriela Alvarez , Bittner Christian , Stein Stefan , Büschel Michael
Published: July 2017

Management

Production from oil fields can be increased by enhanced oil recovery (EOR) techniques. Among several other EOR methods, the injection of chemicals has been studied since the 1970s.

In that time, anionic polyacrylamides (PAM) have proven to be efficient viscosifiers for moderate field conditions to reduce mobility of the displacement fluid, thus increasing reservoir sweep efficiency. Surfactants mobilize oil that is trapped in formation rock pores by lowering the oil/water interfacial tension.

Polymer flooding is now considered an established technology, which is applied on a commercial scale in several countries. In contrast, the commercial use of EOR surfactants is still limited despite more than 50 years of research history in this area. This can be partly explained by the technical complexity of EOR surfactant projects and the higher cost.

The implementation of a chemical EOR (cEOR) project is often a significant endeavor that not only poses technical challenges but also represents substantial financial risk. In recent years, cEOR projects also target challenging conditions such as high temperatures, high salinity, and demanding locations such as offshore fields.

A multidisciplinary and integrated approach is vital to managing technical, regulatory, and economic challenges with a team of geoscientists, engineers, chemists, and mathematical modelers working together to achieve an increase in incremental oil recovery at the lowest total cost of ownership.

From Laboratory to Full Field Once the operator has verified that injection of chemicals is a viable option to enhance oil recovery in one of its assets, a laboratory-screening program will start to identify a suitable chemical solution that not only will perform under specific reservoir conditions but also meet financial targets. The principal workstreams of a cEOR project are illustrated in Fig. 1.

EOR-specific application test work is needed, such as rheology evaluations for polymers, or phase-behavior and interfacial-tension measurements for surfactants. The quality of the work will rely considerably on the collaboration of an experienced multidisciplinary team mainly because the experimental evaluations cover a broad range of knowledge fields such as chemistry, physical chemistry, and reservoir and petroleum engineering.
Technology Focus: Wellbore Tubulars (June 2017)
Authors: Samuel Robello
Published: July 2017

Technology Focus

This month, I would like to bring out some thoughts on the advancements that have been made in the tubular area, an important and complex system that has a very, very small diameter/length aspect ratio and a high slenderness ratio, making it a thin wall.

Sometimes, while flying at an altitude of 35,000 ft, I think of a drillstring and the fact that, if I could hold it from the plane, it would be touching the ground. Amazingly, we are trying to predict the health of this long string in a constrained wellbore with a few sensors at the bottom. It is like saying I will touch your toe with a few instruments and then predict the health of your whole body. The greatest challenge is being able to bring together all aspects of tubulars to advance in lockstep with one another. We have advanced tremendously not only in the modeling but also in materials and manufacturing technologies. Tubular manufacturing, recommended practices for material strength, and wear are important for drillstring integrity. We have seen in recent years many technological advancements in tubular-manufacturing technology. Tubulars also have become part of the data-transmission network and slowly will converge with the data-handling and data-transmission systems. Common thoughts for drilling engineers—when it comes to planning and drilling—often focus on torque and drag, which concern tubulars. Even though we have advanced in the prediction of torque, drag, and hookload estimation, challenges remain concerning drillstring integrity, such as prediction of tool failures, buckling, and string stability.

Can we couple fewer casings? Various underlying arguments could be made to answer this question. In the world of exponential technologies, there are many opportunities where we are breaking the status quo to reduce nonproductive time by providing shorter connection times. One of the emerging technologies is brazing of the connection, leading the way to coupling fewer casing runs, which can be automated very well in the future with an autowelding tong on the rig floor instead of casing tongs as the casings are run into the hole.

I have selected papers that present a balanced perspective on the advancement of tubulars technology. Also, I would like to encourage attendance at the tubular session in the upcoming SPE Annual Technical Conference and Exhibition in San Antonio.

Success of Deepening Workovers in Permian Basin Carbonates
Authors: Babaniyazov A , Bazin P. M
Published: July 2017

With the growing numbers of aging wellbores, recompletion programs help to reduce temporarily abandoned well counts, identify and prove future development potential, boost production and maximize return on investment. Typically base well completion programs have been composed of four main project types: recompletions, rework in the existing zone, sidetracks, and deepenings. This paper summarizes the lessons learned and recommendations from an active deepening campaign in the Permian Basin.

Deepening projects provide a cheaper and lower risk alternative to drilling new wellbores and can achieve the same objectives of zone testing and infill drilling potential evaluation. Once infill potential is proved up through deepening projects further value and scale can be exploited through infill drilling programs.

Two types of deepenings were executed, open hole and cased hole. Casedhole deepenings are more complex and costly, but must be attempted in the cases where openhole deepening is not feasible. Such cases may include deepening across water-bearing or depleted zones, deepening in prolonged pay intervals (>350ft), zones with poor hole stability or incompatible formation fluids. In a stacked pay carbonate rock the stimulation is an important part of the completion process. Therefore deepening projects may have different scopes which may include some isolation work in open or casedhole, single-stage or multi-stage acidizing and fracturing.

The three key pillars which must be in place to deliver a successful deepening program are sound wellbore conditions, reliable well history, and proper equipment selection. Given that deepening projects are implemented less frequently than other well intervention activities and new drilling activity, the equipment selection and the understanding of how to operate that equipment become critical success factors in these projects. It was observed that the time and cost associated with wellbore cleanouts before deepening may drastically change the project economics. The risks associated with poor well integrity and the presence of junk or fish in the wellbore need to be quantified in the candidate selection phase. Changing from roller-cone to PDC bits and adjusting drilling parameters increased the deepening ROP by 300%.

This paper compares the historical performance of 10 deepening projects. It contains a list of operational risks and follow-up plans needed to ensure cost effective and safe execution.

Aim:
Develop an accessible exercise to engage underserved populations about research funding priorities; analyze the criteria they use to prioritize research; contrast these criteria to those currently used by Patient Centered Outcomes Research Institute (PCORI).
Materials & methods:
Academic and community partners collaborated to develop an Ipad exercise to facilitate group deliberation about PCOR funding priorities. 16 groups (n = 183) of underserved individuals in both urban and rural areas participated. Recordings were qualitatively analyzed for prioritization criteria.
Results:
Analysis yielded ten codes, many of which were similar to PCORI criteria, but all of which challenged or illuminated these criteria.
Conclusion:
Directly involving underserved populations in determining funding criteria is both feasible and important, and can better fulfill PCORI’s goal of incorporating patient priorities.
Influence of clinicians' experience and gender on extraction decision in orthodontics
Authors: Saghafi Niousha , Heaton Lisa J. , Bayirli Burcu , Turpin David L. , Khosravi Roozbeh , Bollen Anne-Marie
Published: July 2017

Objective:

To determine whether, in Class I borderline cases, experienced orthodontists choose nonextraction treatment more frequently than do orthodontists with less experience. A secondary aim was to evaluate whether clinicians' gender and place of education play a role in extraction decision making.

Materials and Methods:

An online survey was developed using three Class I borderline patient cases. The survey included questions about clinicians' demographics as well as questions about the selected cases. The survey was distributed to approximately 2000 clinicians through the American Association of Orthodontics.

Results:

Of the 253 responses collected, a trend was observed wherein clinicians with more than 15 years of experience preferred an extraction treatment option more frequently than did clinicians with less than 5 years of experience. There was no association between gender and place of education and the decision to extract in the selected borderline cases. Crowding, patient's profile, and mandibular incisor inclination were among the top three reasons chosen by clinicians for both the extraction and nonextraction treatment decisions.

Conclusions:

A trend was observed in which clinicians with more experience chose an extraction treatment option more frequently in borderline cases than did those with less experience. Clinicians' gender did not play a role in extraction decision making.

Authors: Sim Hye-Young , Kim Hee-Sun , Jung Da-Un , Lee Ho , Lee Jeong-Woo , Han Kyungdo , Yun Kyoung-In
Published: July 2017

Objective:

To investigate the association between orthodontic treatment and periodontitis in a nationally representative sample of South Korea.

Materials and Methods:

Data from the Fifth and Sixth Korean National Health and Nutrition Examination Survey (KNHANES V, VI-1, and VI-2), conducted from 2012 to 2014, were used in this study. The final sample size consisted of 14,693 adults aged ≥19 years. Logistic regression analysis was performed to assess the association between orthodontic treatment and periodontitis.

Results:

The orthodontic treatment group exhibited a lower prevalence of periodontitis compared with the nonorthodontic treatment group. The adjusted odds ratios for periodontitis in subjects with a history of orthodontic treatment compared with those with no history of orthodontic treatment were 0.553, 0.614, and 0.624, when adjusted for various confounding variables (P < .0001). The subjects with periodontitis were of higher age, body mass index, waist circumference, and white blood cell counts compared with the subjects without periodontitis regardless of history of orthodontic treatment.

Conclusions:

History of orthodontic treatment was associated with a decreased rate of periodontitis.

Dynamic Control of Fuel Cell Powered Water Pumping Station
Authors: Adel M. Sharaf  , Mohamed A. H. El-Sayed
Published: July 2017

An efficient renewable green energy system consisting a hydrogen PEM-fuel cell as an energy sources is simulated and studied in this paper. The proposed green scheme has four separate key components. The first is the green power generation source. The second is the interfacing DC-DC converter used to connect green power generator fuel cell to the load bus. The third is a common DC interface-bus where the generated energy is collected in a DC form. The fourth comprises all interfacing error driven controllers and novel modulated green plug power filter (GPPF) used to reduce ripple variations and stabilize the common DC-Bus voltage. In this paper, the novel multi-loop error driven dynamic controller scheme is implemented for speed control of the PMDC motor. This multi-loop controller comprises three basic loops, the main supplementary dynamic momentum loop to ensure fast dynamic and minimum current and torque ripple content.
The proposed fuel cell generation scheme provides efficient and optimum dynamic operation to enhance system performance and secure energy supply. The proposed integrated hybrid system with all subsystems has been simulated using the Matlab Simulink/Sim-Power software environment and validated for voltage stabilization, efficient utilizations and enhanced power quality under different operating conditions, sudden load excursions, despite the non-linear volt-ampere characteristic of the fuel cell DC generator source.

The present study focused on the preparation and antioxidant studies of inclusion complexes of some compounds of 4-Thiazolidinone derivatives with β-cyclodextrin. The inclusion complex has been prepared in order to increase solubility and bio-accessibility of the parent compound. The experiment was conducted by taking 2-Hydrazinobenzothiazole as a starting material and a series of compounds and their inclusion is prepared from it. Taking into account on their physical, thermal and spectral characteristics (UV, IR and NMR), the formation of compounds and their inclusion complex are confirmed. From the antioxidant activities of compounds and inclusion complex, it has been found that inclusion complex has displayed more effectively than the original compounds.

Published: July 2017

A series of 2, 5-disubstituted - 1, 3, 4 – oxadiazoles (4a-o) were synthesized on refluxing hydrazine carbothioamides with iodine and potassium iodide in ethanolic sodium hydroxide solution starting from methyl-3-amino-4-hydroxy benzoate via synthesis of an intermediate methyl-2-substitutedaryl-1, 3-benzoxazole-5-carboxylates and 2-substitutedaryl-1, 3-benzoxazole-5-carbohydrazides. The newly synthesized compounds were characterized on the basis of spectral (FT-IR, 1H-NMR, MS) and elemental analysis. All these compounds were screened for anticonvulsant activity using Maximal Electroshock (MES) and subcutaneous pentylenetetrazole (scPTZ) method. Anticonvulsant activity was shown by majority of the synthesized compounds when given i.p. to mice. Among the tested compounds 4e, 4j and 4o were considered to have potent anticonvulsant activity comparable to that of standard drugs Phenytoin and Carbamazepine. Compounds 4e, 4g, 4h, 4i, 4k and 4m passed the rota rod test successfully without any sign of neurological deficit.

Eckhardt-Gramatté Music Library: Chronology of a Building Project
Authors: Guise Janneka
Published: July 2017

On August 10, 2015, the Eckhardt-Gramatté Music Library closed the doors of the space it had occupied at 65 Dafoe Rd at the University of Manitoba since it opened in 1965, and prepared to move to its new home down the street in the Taché Arts Complex, 136 Dafoe Rd. The move itself took three days, and was the culmination of eight years of planning, design, and preparation. The Library re-opened in its new home approximately one month later, on September 26, 2015. The new space is 2.5 times larger than the old, has nearly three times the number of student study seats, and every shelf has room for growth. This article documents a brief history of the Library, and chronicles the move to the new location from the announcement in 2008, through the space planning, design, and construction phases, to moving day and beyond. At the end of the article is an overview of lessons learned and a recommended reading list for anyone lucky enough to enter into a new library building project.

A instituição de grupos colaborativos como ambiente para a formação na docência
Authors: Da Costa Leila Pessôa , Pavanello Regina Maria
Published: July 2017

Este artigo apresenta um recorte de pesquisa cujo objetivo foi investigar possíveis contribuições de um processo colaborativo para a aprendizagem e a prática docente de professoras de 4ºs e 5ºs anos do Ensino Fundamental (EF) com referência ao conteúdo Números e Operações (NO). Participaram da investigação dez professores atuantes, nesses anos do ensino, em duas escolas da rede municipal de uma cidade da região noroeste do Paraná. Foram utilizados para a análise e reflexão do processo de ensino e de aprendizagem dados coletados em entrevista inicial e final, observações em sala de aula, análise de materiais utilizados pelas professoras e pelos alunos, e documentos administrativos e pedagógicos que subsidiam o trabalho escolar. O processo de reflexão em grupo ocorreu em diferentes momentos - horas atividades (HAs), intervalos de aula, em sala de aula e no contra turno - a partir da produção dos alunos sobre o tema. A análise do processo empreendido constatou o aprofundamento dos seus saberes das professoras relativo ao tema NO, a produção de mudanças em sua prática e na sua concepção sobre os processos de ensino e de aprendizagem da Matemática.

Este artigo busca sistematizar algumas reflexões decorrentes de uma pesquisa de doutorado, cujo objetivo foi compreender o processo de desenvolvimento profissional na perspectiva do letramento estatístico em contextos colaborativos, buscado também evidenciar indícios do desenvolvimento profissional dos participantes de um grupo de professores e futuros professores da Educação Infantil e anos iniciais do Ensino Fundamental. Numa abordagem qualitativa, optamos pelo estudo de caso, o do Grupo “Estatisticando”. Com esse trabalho num contexto colaborativo, consideramos que contribuímos para o desenvolvimento profissional e a formação de professores capazes de lidar com a Estatística, confiantes de que podem trabalhar com seus estudantes numa perspectiva de letramento estatístico.
Resolução de problemas e seus significados: negociações ocorridas em uma Comunidade de Prática de professores que ensinam matemática
Authors: Da Silva Wanusa Rodrigues , Manrique Ana Lúcia
Published: July 2017

Este artigo é um recorte de uma pesquisa que procurou identificar quais negociações de significado envolvendo a Resolução de Problemas ocorreram no núcleo da PUC/SP, constituído por acadêmicos, professores da Educação Básica e licenciandos, no âmbito do Programa Observatório da Educação (Obeduc/CAPES). Adotamos como perspectiva teórica o conceito de Comunidades de Prática (CoP) de Lave e Wenger (1991) e Wenger (2001). Utilizamos como instrumentos para a coleta de dados as transcrições das gravações em áudio dos encontros realizados, o diário de campo da pesquisadora e a observação participante, que serviram de base para selecionarmos episódios representativos quanto às negociações de significado. Como resultados, apontamos que o processo de conhecer e aprender como trabalhar com a Resolução de Problemas foi validado pela CoP como parte importante da prática social do professor que ensina matemática. Além disso, o entendimento sobre Resolução de Problemas comum ao grupo e que passou a fazer parte do repertório compartilhado da CoP foi sendo construído com o tempo, este significado foi negociado e renegociado em diversos encontros, e não ocorreu livre de conflitos. Quanto às diferentes formas de participação na CoP, assinalamos que os novatos tiveram uma participação mais periférica, ao passo que outros, especialmente os professores, se firmaram como membros experientes, de participação plena. Consideramos que grupos como os do Obeduc se constituem em importantes espaços formativos, pois por serem potenciais Comunidades de Prática, se constituem em contextos em que é possível negociar significados sobre aquilo que é relevante e derivar deste processo aprendizagens como formas de participação social.

Authors: A. Kechebar M. S. , S. Karoune , K. Laroussi , A. Djellouli
Published: July 2017

We studied the richness of phenolic compounds and the antioxidant activities of Opuntia ficus indica L. cladodes by
comparing two types of extraction, maceration and soxhlet made with methanol / water (8 : 2, v/v). The results showed
that the extraction by maceration is better than that by soxhlet with a total polyphenol concentration of 36.7 mg GAE/ g
DW, a total antioxidant activity of 18.5 mg GAE/ g DW and an IC50 of 77.5 μg/ml against DPPH radical scavenging.
These results are very vaforable for a sustainable valorisation of the prickly pear cladodes for medicinal, pharmacological
and alimentary fields.
