Novel Enhanced–Oil–Recovery Decision–Making Work Flow Derived From the Delphi–AHP–TOPSIS Method: A Case Study
Authors: Liang Bin , Jiang Hanqiao , Li Junjian , Yang Hanxu , Chen Wenbin , Gong Changcheng , Qu Shiyuan
Published: January 2018

The process for the enhanced-oil-recovery (EOR) strategic decision is a thorny process that depends on proper evaluation, rational understanding of complex relationships, and quantitative assessment of multiple categories, including economic considerations, dynamic field production, reservoir numerical simulation, and other relevant elements. Using the Delphi-AHP-TOPSIS method (Joshi et al. 2011), which combines the Delphi method, analytic hierarchy process (AHP), and the technique for order preference by similarity to ideal solution (TOPSIS), we develop and present in this paper a decision-making work flow to meet this challenge.

This technological process is divided into three phases. The first phase is the Delphi method, in which key performance factors and subfactors are identified and quantitatively evaluated using expert judgment. The second is the AHP, in which a synthesis of the influence of factors and subfactors is acquired with a pairwise-comparison matrix. The third phase is the TOPSIS, in which the final ranking of candidate EOR projects is given using the monotonic utility function. A typical polymer-flooding EOR decision-making case is presented for better understanding.

The proposed work flow helps geoscientists acquire a comprehensive understanding of the factors in an existing project and select the optimal alternative. The approach not only minimizes the decision makers’ bias, combining the influence of technical and nontechnical factors, but also helps practitioners respond quickly to the oil market and reservoir dynamic performance rationally. This is, to our knowledge, the first time that the Delphi-AHP-TOPSIS method has been introduced to EOR decision making in the petroleum field.
In–Situ Dilation Affects Solvent–Assisted Steam–Assisted–Gravity–Drainage Performance: The Case of a Shallow Athabasca–Type Oil–Sands Reservoir
Authors: Abbasi Asl Y.. , Chalaturnyk R. J.
Published: January 2018

It is generally accepted that solvent/steam injection in heavy-oil/bitumen reservoirs outperforms steam-only injection in terms of oil-recovery rate, ultimate oil recovery, and steam/oil ratio (SOR). Important parameters in the design of solvent-assisted steam-assisted-gravity-drainage (SA-SAGD) are solvent selection, injection strategy, and solvent retention in situ. The role of geomechanics in optimal application of SA-SAGD, however, remains largely unexplored.

Recent studies suggest that solvent transport, solvent-dilution effect, and the temperature distribution around the edge of the steam chamber have major control over SA-SAGD performance. In SA-SAGD, elevated temperature and solvent concentrations within a few meters of the steam-chamber edge reduce the virgin-oil viscosity, causing oil drainage. However, this is the same region where geomechanically induced volume changes alter porosity, permeability, and relative permeability profiles. These alterations could improve the convective-heat transfer and solvent dispersion into the cold bitumen zone, and could also enhance the drainage rate. Consequently, the solvent/oil-phase behavior, steam-chamber growth, and solvent retention and distribution will be affected. This chain of events could have an effect on optimal solvent selection and solvent/steam-injection scenarios. These geomechanical considerations are of particular interest for bitumen deposits, both oil sands and carbonates, where chemical, thermal, and fluid pressures can impose significant volume changes within the reservoir, especially in shallower, lower-confining-stress settings.

The role of geomechanics in SA-SAGD was explored numerically by use of a sequentially coupled modeling approach with STARS (CMG 2015a) and FLAC (Itasca 2016). A 2D shallow-depth homogeneous-oil-sands-reservoir geomodel, with properties similar to the Underground Test Facility (UTF) Phase A project, was constructed (Edmunds et al. 1994). Studies were conducted at two scales: the edge of the steam chamber and the reservoir scale including underburden and overburden. The results of these numerical studies revealed that geomechanics considerations directly affect the optimal solvent-type selection and injection strategy during a high-pressure SA-SAGD process. These studies provide valuable direction for further detailed mechanistic studies (both numerically and experimentally) and provide valuable input to the challenges of optimizing SA-SAGD processes in oil sands.

Audio-Visual Materials in an Integrated Literacy-Mechanical Skills Training Program for Young Unemployed Adults
Authors: Cap Orest , Trosky Odarka S. , Wynes Barbara , Cutts Robin
Published: January 2018

This article describes how audio-visual materials were selected and usedfor a group of thirty unemployed young adults, ranging in ages (17-21), attending an integrated literacy-mechanical skills program. This program consisted of an initial two months of class activities followed by approximately seven months in the field and a final two weeks in class. The audio-visual materials which met Vander Meer's (1973) criteria of appropriateness, to reflect the curriculum and to elicit expected and desired behavior in the learner, were selected on the basis of the Von Mondfrans and Houser six step paradigm (1973) to relate to performance-based objectives. The selected materials did not necessarily reflect the very best nor the most recent in the field, rather they represented the best and most recent from those readily available. Evaluation through questionnaires, reports, observations and participant comments indicated that the audio-visual materials used in the program closely related to the three main functions of audio-visual materials in vocational instruction.
Styles de navigation sur un site Web chilien pour des enseignants d’espagnol | Browsing Styles on a Chilean Web site for Teachers of Spanish
Authors: Meza Fernández Sandra , Marquet Pascal
Published: January 2018

Cet article présente une étude qualitative de l’usage de ressources numériques d’un cours universitaire de formation d’enseignants d’espagnol au Chili. L’analyse compte 3882 traces laissées sur le site Web Didactique de Langue Castillane (DLC), sur une période de 18 semaines. Les résultats montrent que deux familles de facteurs déterminent la correspondance entre la structure du site dédié à la formation et le type de navigation des usagers : les deux facteurs principaux sont le mode d’apprentissage et la stratégie de visite, et les deux facteurs secondaires sont le genre et la filière d’étude. De la recomposition des variables émergent quatre profils de navigation : le profil A atteint 80 % de préférence pour les tâches de lecture, suivi par les profils B et C avec 60 %, tandis que le profil D montre une préférence marquée de 60 % pour les tâches de familiarisation avec la page Web.This article presents a qualitative study about the use of digital resources in a Spanish teacher training course in Chile. The study traces 3,882 visits to the Website Didactics for Castilian Language over a period of 18 weeks. The results show that two categories of factors determine the correlation between the structure of the site dedicated to training and the type of navigation by the users: The two main factors are the learning style and the visit strategy, while the two secondary factors are the genre and the field of study. Four navigation profiles emerge from the recomposition of the variables: profile A shows a marked preference of 80% for the reading tasks, as do profiles B and C with 60%, while profile D shows a marked preference of 60% for the tasks of familiarization with the Web page.

Remote assistive technology training in Newfoundland and Labrador’s rural schools: Is there a need? | Perceptions des enseignants quant au besoin de formation en technologie d’assistance dans les écoles rurales de Terre-Neuve et du Labrador
Authors: Maich Kimberly , Van Rhijn Tricia , Woods Heather , Brochu Kimberly
Published: January 2018

This study examined the perceptions of teachers in rural Newfoundland (NL) about their current ability to support the use of assistive technology (AT) in their classrooms, and identified possible training needs that could be accomplished remotely. Thirty-two educators from rural areas of NL completed an online survey with a mix of closed- and open-ended questions. Five dimensions were explored for this needs assessment including: current beliefs, skills, use, comfort level, and perceptions of AT; identification of specific service needs; learning preferences; available technology; and potential barriers. Results reveal that teachers had positive attitudes about the utility and use of AT in their classrooms, yet were not fully implementing AT with their student’s due to a variety of perceived barriers. The study identified a clear need for AT teacher training. Based on the results and the research, literature recommendations are made for teacher training to address the need identified by this study.Cette étude a porté sur les perceptions des enseignants dans les régions rurales de Terre-Neuve de leur capacité actuelle d’appuyer l’usage des technologies d’assistance (TA) dans leurs classes et a cerné de possibles besoins de formation que l’on pourrait combler à distance. Trente-deux éducateurs de régions rurales de Terre-Neuve ont rempli un sondage en ligne comprenant un mélange de questions ouvertes et fermées. Cette évaluation des besoins a exploré cinq dimensions : croyances, compétences, utilisation, perceptions et degré de confort actuels quant aux TA; détermination de besoins de services précis; préférences d’apprentissage; technologie disponible; obstacles potentiels. Les résultats révèlent que les enseignants avaient des attitudes positives quant à l’utilité et à l’utilisation des TA dans leurs classes, mais ne les mettaient pas entièrement en œuvre avec leurs élèves parce qu’ils percevaient une variété d’obstacles. L’étude a cerné un besoin manifeste de formation des enseignants relativement aux TA. Selon les résultats et la recherche, des recommandations sont avancées pour que la formation des enseignants réponde au besoin cerné dans cette étude.
Field Test Evaluation of Educational Software: A Description of One Approach
Authors: Tovar Mariela , Barker Nicholas
Published: January 2018

Educational evaluators in general have traditionally recognized the needto incorporate data from potential users in designing evaluation studies. In the field of courseware evaluation, however, there has been a great deal of emphasis placed on expert judgment as a source of data for evaluating computer-based educational materials. Although courseware reviews are extremely useful, they are not substitutes for field tests;each provides a different type of information that evaluators may use in order to determinethe quality of an instructional product.This paper reports on the evaluation of a courseware designed to assist the writing of the lower-case alphabet. The main objective of the article is to demonstrate an evaluation design which provided adequate answers to our evaluation questions, allowed us to perform multiple comparisons to support our conclusions, and was also practical enough to be used in a normal classroom situation without disturbing everyday activities. Three criteria for selecting a design are presented followed by a description of the courseware evaluation.
Mon ami Google : une étude des pratiques des futurs enseignants du Québec en recherche d’information | My friend Google: A study on the information seeking process of Quebec’s pre-service teachers
Authors: Dumouchel Gabriel , Karsenti Thierry
Published: January 2018

While Quebec’s students mainly use Web search engines like Google to find information for their studies, teachers are tasked with giving them the proper training to do it efficiently. But are future teachers well prepared to accomplish their mission? This study analyzes the information seeking process used by Quebec’s pre-service teachers to find information on the Web. Results show that a majority of them are novice information searchers; they rarely plan ahead for their Web searching, they use basic search strategies, and scarcely diversify their searching tools. Results are discussed and recommendations are suggested to improve the information seeking process taught to pre-service teachers.Alors que les élèves du Québec cherchent prioritairement de l’information sur des moteurs de recherche comme Google, il revient aux enseignants de les former à le faire efficacement. Mais la relève est-elle bien préparée pour accomplir cette mission? Cette étude vise à décrire et analyser les pratiques déclarées et effectives de futurs enseignants québécois en recherche d’information sur le Web. Les résultats démontrent qu’ils emploient principalement un mode d’action novice : peu ou pas de planification, stratégies de recherche basiques et faible diversification des outils. Une discussion critique des résultats et des recommandations en formation initiale viennent clore cet article.
Project Management for Computer-Based Training Development
Authors: Schwier Richard A.
Published: January 2018

This article deals with the management of instructional developmentprojects for computer-based training (CBT), and is primarily aimed at project managers working with a team of instructional developers for a corporate client. Two issues are discussed: a) estimating the size of a CBT project, and b) performing a cost-benefit analysis. These issues are important for projecting costs, tracking performance and justifying development expenditures.This is a fictionalized case study. The methodology, examples, concepts and estimates are composite sketches drawn from several projects, based upon the author's experiences while working as a CBT project manager. Actual figures and clients have been intentionally obscured to protect the proprietary rights of all parties involved.The reader should be cautioned that the article presents only one approach to project development and estimation. Wholesale application of the approach described is not recommended, as every project will introduce novel interactions of resources and variables which mandate different treatment. Still, it is hoped that the reader will draw upon the ideas presented to refine project management approaches already used.
Guitars and Makerspace: Examining the Experience of First Nations Students | Guitares et laboratoires ouverts : examen de l’expérience d’élèves des Premières Nations
Authors: Wilson Jay R , Gobeil Marc
Published: January 2018

This research project examined the impact on student engagement of a makerspace approach in an all-First Nations high school. First Nations learners have many factors limiting their success in the K-12 system such as lack of connection to the curriculum, limited cultural relevance of course content, and poor attendance. A common concern for those working with First Nations students is how to deliver a learning experience that is engaging and assists students in earning enough credits to graduate. In this case study, a makerspace approach to learning was used to engage and support learners. A makerspace is a learning context where participants are supported and encouraged to design and create as part of required learning, to meet curricular objectives, or to creatively explore their own ideas. The program at the focus of this research introduced students to 3D computer design technology and (computer numerical control) CNC wood milling technology to make electric guitars. This project used a case study design to determine ways to improve the school experience of First Nations students through unique course design. The findings show that the experience for students was positive, engagement increased, and attendance showed improvement.Ce projet de recherche s’est penché sur l’incidence d’une approche « Makerspace » (laboratoire ouvert) sur l’engagement des élèves dans une école secondaire fréquentée uniquement par des membres des Premières Nations. Plusieurs facteurs limitent la réussite des apprenants des Premières Nations dans le système scolaire de la maternelle à la 12e année, comme un manque de connexion au programme, la pertinence limitée du contenu des cours et un haut taux d’absentéisme. Les personnes qui travaillent auprès des élèves issus des Premières Nations ont comme préoccupation commune l’offre d’une expérience d’apprentissage qui engage les élèves et les aide à obtenir suffisamment de crédits pour obtenir leur diplôme. Dans cette étude de cas, une approche de laboratoire ouvert a été utilisée pour faire participer les apprenants et les appuyer. Un laboratoire ouvert est un contexte d’apprentissage dans lequel les participants sont soutenus et encouragés à concevoir et à créer, que ce soit en vue de l’apprentissage requis, pour atteindre des objectifs du programme ou pour explorer avec créativité leurs propres idées. Le programme au cœur de cette étude a fait connaître aux élèves la technologie informatique de conception en 3D et la technologie de fraisage du bois par CNC (commande numérique par ordinateur) pour fabriquer des guitares électriques. Ce projet a utilisé une conception d’étude de cas afin de déterminer des façons d’améliorer l’expérience scolaire des élèves des Premières Nations par l’entremise d’une conception de cours unique. Les conclusions démontrent que l’expérience a été positive pour les élèves, que leur engagement a augmenté et que leur taux de présence s’est amélioré.
Using Brunerian Learning Theory with Educational Simulations to Teach Concepts
Authors: Winer Laura R. , Schmid Richard F.
Published: January 2018

The present study maintains that consistently effective leaming materialscan best be generated if the prescriptions instructional designers use are founded on learning theory. It is also considered critical that cognitive processes central to the task demands and strategies employed to address them be established. To be practical, we further recommend that only a single, process-oriented lesson, rather than individualized treatment, be implemented. Instructional simulations met these criteria, being tightly bound to Bruner's theoretical approach, and inherently capable of addressing aptitude deficiencies. Subjects were assessed for spatial visualization ability, grouped, randomly assigned to simulation or non-simulation treatments, and tested immediately, one week, and five weeks after instruction. The simulation significantly increased the high-aptitude learners' efficiency (and initially effectiveness), and low-aptitude learners' effectiveness. The validity of a theory-based, aptitude-enhancing, standardized approach was supported, andis discussed.
Lecturer e-Training Program to Support University Teaching | Programme d’e-formation pour les chargés de cours pour appuyer l’enseignement universitaire
Authors: Tik Chan Chang
Published: January 2018

This article attempts to explore the extent to which Lecturer e-Training Program (LeP) supports lecturers in their preparation for student-centred teaching. LeP was conducted in a blended mode, that is, it involved an online self-paced learning module followed by an interactive online discussion and ended with a face-to-face action learning. It was compulsory for all lecturers in this university to enrol in LeP. The data collection involved distributing questionnaires to all 36 lecturers. After that, 16 lecturers were selected at random for one-to-one structured interviews. In this study, it was found that LeP contributed significantly to the lecturer preparation for student-centred teaching, in particular, Stage 2 (Online Discussion) and Stage 3 (Face-to-Face Action Learning). Lecturers in this university were mostly homogeneous with regard to culture. It would be interesting to test LeP across cultural diversity as it was believed Asians and Westerners think differently.Le présent article vise à explorer la mesure dans laquelle le Programme d’e-formation (Lecturer e-Training Program) appuie les chargés de cours dans leur préparation pour un enseignement centré sur l’étudiant. Le Programme a été réalisé en mode hybride, c’est-à-dire avec un module d’apprentissage en ligne à rythme libre, qui a été suivi d’une discussion interactive en ligne et finalement d’un apprentissage par l’action réalisé en personne. Tous les chargés de cours de cette université devaient s’inscrire au Programme. La collecte de données a consisté à distribuer des questionnaires aux 36 chargés de cours. Ensuite, 16 d’entre eux ont été choisis au hasard pour des entrevues structurées en tête-à-tête. Dans cette étude, on a conclu que le Programme contribuait de façon importante à la préparation du chargé de cours pour un enseignement centré sur l’étudiant, particulièrement le deuxième stade (discussion en ligne) et le troisième (apprentissage par l’action réalisé en personne). La culture des chargés de cours de cette université était surtout homogène. Il serait intéressant de tester le Programme à travers une diversité culturelle, car on croit que les personnes asiatiques et occidentales pensent différemment.
An Insight into Space Weather
Authors: Mishra Ashish , Kumar Mukul
Published: January 2018

The present article gives a brief overview of space weather and its drivers. The space weather is of immense importance for the spaceborne and ground-based technological systems. The satellites, the power grids, telecommunication and in severe conditions the human lives are at risk. The article covers the effects of solar transient activities (e.g. Solar flares, Coronal mass ejections and Solar winds etc.) and their consequences on the Earth’s atmosphere. The space weather is the change in the conditions of interplanetary space because of the solar transient activities. We also discussed the importance of the solar wind which is a continuous flow of the charged energy particles from the Sun to the Earth in respect of the space weather. This article also put light on the Sun-Earth connection and effects of the space weather on it. The Earth’s magnetosphere, formed by the interaction of solar wind and Earth’s magnetic field behaves like a shield for the Earth against the solar wind.
An Insight into the Solar Dynamo Theory
Authors: Tiwari Babu Ram , Kumar Mukul
Published: January 2018

The Sun manifests its magnetic field in form of the solar activities, being observed on the surface of the Sun. The dynamo action is responsible for the evolution of the magnetic field in the Sun. The present article aims to present an overview of the studies have been carried on the theory and modelling of the solar dynamo. The article describes the alpha-omega dynamo model. Generally, the dynamo model involves the cyclic conversion between the poloidal field and the toroidal field. In case of alpha-omega dynamo model, the strong differential rotation generates a toroidal field near the base of the convection zone. On the other hand, the turbulent helicity leads to the generation of the poloidal field near the surface. The turbulent diffusion and the meridional circulation are considered as the two important flux transport agents in this model. The article briefly describes the theory of solar dynamo and mean field dynamo model.

A abordagem qualitativa nas ciências sociais e humanas enriquece a perspetiva daquele procura saber mais, ir mais fundo, ao amago dos comportamentos e da sua etiologia, na implexa rede que é o Homem e as suas relações. Estes campos da Ciência dotam, ou procuram dotar, o investigador com os instrumentos e do conhecimento para anatomizar o ser social, o Homem, o indivíduo. Não é descurado afirmar que não se pode investigar adequadamente o ser humano, sem a utilização de uma perspetiva multidisciplinar e/ou interdisciplinar, intrínseca às ciências sociais e humanas, bem como às ciências da natureza e da saúde (Chizotti 2006).

El artículo se cuestiona, sobre la importancia y lugar que dan a la investigación formativa las instituciones educativas de nivel medio de la ciudad de Popayán, Cauca, en Colombia. En un ejercicio propio del enfoque cualitativo, basado fundamentalmente en el análisis sociológico del discurso, se analiza el corpus documental, a partir de categorías de análisis (percepción, practica, disposición institucional y currículo académico), que dan sentido a la construcción de cuatro Tipologías de instituciones de cara a la práctica investigativa en aula (Aventajada, Dotada, Empírica, Desprovista). El artículo enfatiza en el rol fundamental del docente frente a la pedagogía de la enseñanza de la investigación, sin dejar de lado que, en la implementación de una cultura científica e investigativa, juega un papel fundamental un ordenamiento jurídico expreso y políticas públicas que amparen dicha labor, lo cual se representa en escenarios, infraestructura y apoyo institucional.
Tornar-se Pai ou Mãe: O desenvolvimento do processo parental
Authors: Martins Cristina Araújo , Abreu Wilson Jorge Correia Pinto De , Figueiredo Maria do Céu Aguiar Barbieri De
Published: January 2018

De entre as transições que o sistema familiar enfrenta, a transição para a parentalidade é considerada como uma das mais dramáticas e intensas. Acresce complexificação ao sistema familiar e requer reorganização de identidades e papéis. Este estudo procurou compreender como se desenvolve a transição para o exercício da parentalidade durante o primeiro ano de vida da criança, através do recurso à Grounded Theory e entrevistas semiestruturadas (total de 75), complementadas com observação, em cinco momentos de colheita de dados. A teoria explicativa emergente evidencia o tornar-se pai ou mãe como complexo processo de transformação identitária que ocorre em contínua interação com múltiplos sistemas interrelacionados e sobreleva a temporalidade da condição parental. A metodologia adotada no estudo possibilitou a compreensão da natureza psicossocial do fenómeno parentalidade, produzindo conhecimento que se constitui como ponto de reflexão e sensibilização para a mudança e inovação dos contextos de prática de enfermagem com famílias.

Este trabalho discorre sobre as efetividades sociais do PNAE nos municípios de Anápolis-GO e Jaraguá-GO para os agricultores familiares sob a ótica dos elementos de segurança alimentar tratada de maneira ampla. A comparabilidade tornou-se importante analiticamente pela presença de um ator dinamizador da rede de segurança alimentar em Jaraguá-GO. Utilizou-se da EBIA (Escala Brasileira de Insegurança Alimentar) que é um método de mensuração da situação alimentar domiciliar, que objetiva captar distintas dimensões da Insegurança Alimentar (IA) e de métodos e instrumentos já utilizados em outros estudos (Segall-Corrêa & Marin-Leon 2009; Almeida et al. 2015), que compreendem indicadores sócio demográficos, socioeconômicos, ambientais e de hábitos alimentares para caracterizar de forma ampla a SAN dos agricultores familiares. A hipótese principal é que as formas de organização social dos agricultores familiares em cooperativa de Jaraguá-GO promoveu a inclusão social destas famílias ao acessar o mercado de institucional do PNAE e a compor efetivamente a agenda políticas públicas, em contrapartida, o município de Anápolis-GO adquire seus produtos de uma cooperativa localizada em Goiânia-GO, o que não garante a segurança alimentar a partir dos eixos autenticidade e solidariedade e se caracterizou como forma espúria.

Published: January 2018

A educação inclusiva recomenda o acesso a uma educação de qualidade para todos, que permita a apropriação do conhecimento e o desenvolvimento de competências, orientando os indivíduos de acordo com respostas adaptadas às exigências sociais. A escola pública é o garante de respostas de qualidade à diversidade sociocultural, física ou mental do individuo. O objetivo deste estudo vai ao encontro do que é sugerido pelas diretivas nacionais e internacionais para uma escola inclusiva, e pretende analisar qual o processo de avaliação que as equipas multidisciplinares elegem para o desenho do Programa Educativo Individual (PEI). A recolha dos dados será realizada através de questionários e entrevistas a equipas multidisciplinares de educação especial, de 3 agrupamentos escolares. Os resultados preliminares apontam para que apesar de todos terem por base a legislação, cada agrupamento organiza-se de forma própria, não existindo uma uniformização nos processos.

Published: January 2018

Este artigo se refere à análise da forma inovadora na construção do Direito ao Meio Ambiente na jurisprudência interamericana de direitos humanos e da possibilidade de ações internacionais contra um país, a exemplo do Brasil, por denegação de qualidade de vida ambiental. Considerando que a teoria e os tribunais nacionais e internacionais estão reconhecendo a necessidade de proteção ao meio ambiente como um direito humano, este estudo irá avaliar o conteúdo deste direito no Direito Internacional do Meio Ambiente. Esta pesquisa pretende analisar detalhes sobre a intersecção entre os direitos humanos e as bases ambientais para o desenvolvimento sustentável. Neste contexto, será verificada a construção do conceito de proteção ambiental no Sistema Interamericano de Direitos Humanos e casos em que o Brasil foi acionado internacionalmente neste Sistema. Será dado um foco especial ao caso da instalação da Usina Hidrelétrica de Belo Monte, em áreas tradicionais indígenas, na bacia do Rio Xingu e a respectiva ação internacional contra o Brasil. É importante para o desenvolvimento do tema, a análise dos resultados prováveis de uma ação no plano internacional contra o Brasil, pelos problemas nacionais de falta de efetividade, como a denegação de justiça e qualidade de vida.

Published: January 2018

Os padrões temporais de mudança de paisagens só serão revelados através da descrição dos processos que influenciam sua dinâmica. Diante da necessidade de determinar esses processos, este estudo teve como objetivo analisar as dinâmicas de uso e cobertura do solo entre os anos de 1988 e 2016, observando os avanços ou retrocessos na conservação dos ecossistemas durante o período de estudo no município de Brotas-SP. O foco do procedimento metodológico foi a caracterização ambiental do município e a análise de uso e cobertura da terra na avaliação da paisagem utilizando imagens Landsat, relacionadas à área de estudo. Houve um crescimento nas áreas de vegetação natural com diminuição principalmente de áreas para atividades agrícolas. O fortalecimento de espaços dedicados à conservação ambiental deve ser uma premissa da administração municipal para a formulação, implementação e monitoramento de planos, programas e projetos de desenvolvimento urbano, adequando-se à realidade local e, assim, cumprindo seus objetivos.
Macrophyte Occurrence in Response to Anthropogenic Pressure in Reservoir

Published: January 2018

O objetivo deste estudo foi o de avaliar o efeito do uso antrópico do solo sobre a comunidade de plantas aquáticas no entorno de um reservatório artificial consolidado. Foram delimitadas duas unidades paisagísticas (UP) no entorno de um reservatório artificial de mais de 50 anos: a UP1 apresenta baixo impacto antrópico e a UP2 apresenta alto impacto antrópico. No total, foram encontradas 20 espécies de plantas. Apenas duas espécies foram comuns em UP1 e UP2. A UP1 apresentou maior diversidade de espécies (n=18). Os teores de fósforo, potássio, matériaorgânica, cálcio e magnésio foram menores na UP2 (n=4). Pode-se concluir que o processo de barramento permite a ocorrência de maior número de espécies e de plantas de macrófitas, pela conservação do solo adjacente ao reservatório. O baixo impacto antrópico nessa área permite maior diversidade de macrófitas nativas. A intensificação do uso do solo no entorno do reservatório não permite o desenvolvimento de comunidade diversificada de macrófitas, pois empobrece o solo.
A Interdisciplinaridade nas Perguntas de Ciências de Estudantes do Ensino Fundamental: Contribuições da Análise Textual Discursiva
Authors: Ramos Maurivan Güntzel , Thomaz Estrella Marlene
Published: January 2018

O artigo apresenta a análise de 342 perguntas sobre o tema “Água”, propostas por 114 estudantes de três escolas do ensino fundamental da região Sul do Brasil, com vistas a identificar articulações interdisciplinares, associadas ao pensamento complexo, presentes nessas indagações. A investigação buscou responder à seguinte questão: Que revelações podem emergir da análise de perguntas dos estudantes sobre um tema específico de estudo, como “Água”, em relação à interdisciplinaridade e ao pensamento complexo? Da análise textual discursiva das perguntas, emergiram duas categorias: perguntas disciplinares; e perguntas interdisciplinares. O exame do conteúdo das categorias possibilitou a redação de metatextos que revelam que, no enunciado da maioria das perguntas dos estudantes, há envolvimento de modo complexo de pensar e estão presentes relações interdisciplinares, pois 77,8% das perguntas pertencem à segunda categoria. Isso pode ser um indicativo aos professores de como iniciar ações pedagógicas, cujo foco é a interdisciplinaridade.

Este artigo apresenta reflexões sobre a prática pedagógica de Professores, no viés da inclusão, de um estudante que apresenta Deficiência Intelectual (DI). A pesquisa foi realizada em uma escola de educação básica localizada no Centro-Oeste brasileiro, no Estado de Goiás. Por meio da imersão dos pesquisadores na instituição de ensino, investigamos o contexto em que o estudante com DI está inserido, assim como as dificuldades e potencialidades do processo de ensino e aprendizagem. Para tanto, observamos as aulas do ensino médio, de uma Professora Regente (PR), da disciplina de Ciências/Química, e de um Professor de Apoio (PA); e, por fim, nos apropriamos da utilização de questionários, para colaboração no levantamento de dados. Percebemos, no decorrer da pesquisa, as dificuldades de um trabalho em conjunto entre o PR e a PA. Por fim, a partir dos dados coletados e analisados, consideramos que a escola de Educação Básica — em particular e em especial, a escola onde a pesquisa foi realizada - ainda se encontra distante da efetiva inclusão, especialmente por conta das metodologias de ensino utilizadas que estão aquém das necessidades dos discentes.

Published: January 2018

Luminescence bioimaging is widely used for noninvasive monitoring of biological
targets in real-time with high temporal and spatial resolution. For efficient bioimaging
in vivo, it is essential to develop smart organic dye platforms. Fluorescein (FL), a
traditional dye, has been widely used in the biological and clinical studies. However, visible
excitation and emission limited their further application for in vivo bioimaging. Nearinfrared
(NIR) dyes display advantages of bioimaging because of their minimum absorption
and photo-damage to biological samples, as well as deep tissue penetration and low
auto-luminescence from background in the living system. Thus, some great developments
of near-infrared fluorescein-inspired dyes have emerged for bioapplication in vitro and in
vivo. In this review, we highlight the advances in the development of the near-infrared
chemodosimeters for detection and bioimaging based on the modification of fluoresceininspired
dyes naphtho-fluorescein (NPF) and cyanine-fluorescein (Cy-FL).

Background:

Pantoprazole (PTZ) and Levosulpiride (LS) were proven as effective agents for
the treatment of Gastro-Esophageal Reflux Disease (GERD). It is a complex motor disorder that results
in regurgitation of the gastric contents into the lower esophagus with consequent symptoms such as
heart burn, retrosternal pain, dysphagia and belching.

Methods:

A rapid, sensitive, selective and specific liquid chromatography- electro spray ionization
tandem mass spectrometry (LC-MS/MS) method was developed for the simultaneous quantification of
Pantoprazole (PTZ) and Levosulpiride (LS) in spiked Human Plasma. The method utilized SPE as sample
preparation technique and the analysis was carried out on a HPLC system utilizing electro spray
ionization as interface and triple quadrupole mass analyzer for quantification in MRM possitive mode.
Iloperidone was used as internal standard (IS). Chromatographic separation was performed on a Phenomenex
C-18 Column (4.6 mm x 50 mm, 5µ) with an isocratic elution mode utilizing a mobile phase
composition of Solution containing a mixture of 70 volumes of acetonitrile: 30 volumes of methanol
and 10mM ammonium formate (pH 4.0) at the ratio of 80:20 % v/v. The flow rate was maintained at
0.3 mL/min.

Results:

PTZ, LS and IS were detected and quantified with proton adducts at m/z 383.37→200.00, m/z
341.42→112.15 and 426.48→261.00 respectively. The linearity and range was established by fortifying
blank plasma samples in the concentration range of 3.5-2000 ng/mL for PTZ and 3.0-2400 ng/mL for
LS. The correlation coefficient (r2) was found to be ≥ 0.993 for PTZ and (r2) ≥ 0.990 for LS. The lower
limit of quantification for PTZ was 3.5 ng/mL and LS was 3.0 ng/mL. The intra and inter day precision
and accuracy for PTZ and LS were within the limits fulfilling the international acceptance criteria. PTZ
and LS were found to be stable throughout three freeze-thaw cycles, bench top and short term stability
studies.

Conclusion:

The proposed validated LC-MS/MS method offers a sensitive quantification of PTZ and
LS in spiked human plasma and can be utilized for the quantification of PTZ and LS in real-time
samples.
Water vapor formation causing reversible aerodynamic effect on the distribution of aero-algal forms
Authors: T. Pandkar Jogita
Published: January 2018

Aerodynamic is a branch which deals with the study of takeoff and passive transport mechanism of bio-particles with the help of physical and mathematical modules. But there is not a single report on the aero-dynamic study with respect to manipulated meteorological condition. Nagpur being hottest during summer month, the frequency of using air coolers is very high. An air cooler is a device which evaporates water with the help of fan to bring down room temperatures which results into increase in room humidity very much. To study the effect of humidity on the distribution and occurrence of aero algal forms sampling was carried out at three different sites, fitted with air cooler, from April- Mid May, using Rotarod sampler. Total 84 algal forms were recorded from 46 samples collected from three different sites. Cyanophyta was found to be dominant, followed by Bacillariophyta, Chlorophyta and Euglenophyta respectively. Trentipholia is found to be dominant algal forms followed by Chroococcos, Microcystis, Aphanocapsa, Chlorella & Euglena respectively. Forms such as Chroococcidiopsis, Merismopedia, Aphanocapsa, Gleocapsa, Phormidium, Hormidium & Pinnularia were recorded in equal proportion. Forms such as Chlorella, Microcystis, Phormidium & Hormidium reported to be allergenic has been encountered. Irrespective of dry environmental condition with high temperature and low humidity (the condition considered to be favourable for dispersal of aero-algal forms, resulting into high concentration of air-borne algal flora) during sampling period, at all the three sites, minimum number of aero-algal forms were encountered due to increased humidity at the sampling sites. This can be due to manipulated micrometeorological conditions resulting into reversible aerodynamic effect on the aero- algal forms. Humidity of room air is increased by releasing water droplets in the atmosphere which act as a mode of reversible dispersion of aero-algal forms from higher level to the ground level, resulting into reduction in aero-algal counts at human breathing level. This finding, if experimented further with aero-algal and other bio-particles, can be good news for allergy patients.
Effect of heat and drought stress on the expression of regulatory transcription factors and the genes involved in different metabolic pathways
Authors: O. Murali , Mehar Santosh Kumar
Published: January 2018

Plants never encounter stress factors, whether biotic or abiotic in sequence. Mostly they have to face multiple environmental factors in suboptimal level (stressful) at the same time. As a result, the strategy of the plant to survive in such situations demands handling of multiple stresses at the same time by efficient management of the genetic repertoire that the plant has. The plant achieves this by altering expression of transcription factors that regulate the activity of different genes, whose products themselves play the structural and functional roles. In the present study, differentially regulated genes under heat and drought stress from different microarray studies were analyzed to assess the kind of metabolic pathways that are specifically altered (promoted or sacrificed) under heat and drought stress and the transcription factor families which have the governing role in such regulatory processes. It was observed that expression of genes related to metabolism, specifically in the cell organelles like plastids and mitochondria is differentially regulated. Some transcription factor families like AP2-EREBP, NAC, C2H2 and MYB play more important role in the two kinds of stress conditions.
