Studies on Variation in Arecoline Content of Arecanuts Collected from Different Parts of Karnataka
Authors: R. Gurumurthy B. , C. Swathi H. , Sahana J. , Nataraj S. P.
Published: July 2017

ABSTRACT: Arecoline is a nicotinic acid-based alkaloid found in the areca nut, the fruit of the areca palm (Areca catechu). It is an oily liquid that is soluble in water, alcohols, and ether. HPLC method is simple and rapid for determination of arecoline content in areca nut. Areca samples were collected from Shimoga, Davanagere, Chikkamagalur, Chitradurga, Dakshina kannada and Udupi districts of Karnataka, India. The collected areca samples were powdered and arecoline is extracted from samples collected from different hoblies of the districts. The extraction method was optimized to obtain pure arecoline before analysis to separate any interference in order to maximize the specificity and sensitivity of the method. The regionwise arecoline content has been compared. The concentration of arecoline varied from area to area depending on environmental factors, differential processing methods, age of the plantations, varietal differences etc.

O que Bardin diz que os autores não mostram? Estudo das produções científicas brasileiras do período de 1997 a 2015
Authors: Seramim Ronaldo Jose , Walter Silvana Anita
Published: July 2017

Este estudo apresenta a análise de artigos publicados em periódicos brasileiros, no período de 1997 a 2015, que utilizaram o método de análise de conteúdo da autora Laurence Bardin. A metodologia é exploratória, com perspectiva temporal longitudinal, tendo como forma de pesquisa a documental, abordagem quantitativa e qualitativa. Foram analisados 52 trabalhos publicados em língua portuguesa, disponíveis no portal de periódicos Scientific Periodicals Electronic Library (SPELL) e Scientific Electronic Library Online (SCIELO). Para organização e tabulação, foram utilizados os softwares Atlas.ti e Microsoft Office Excel, analisados pelo método da bibliometria, quantificando, descrevendo e prognosticando o processo de comunicação escrita de acordo com a Lei de Bradford, Lei de Lotka e Leis de Zipf (GUEDES, 2012). Além disso, os trabalhos foram explorados qualitativamente de acordo com a aplicação do método e classificados como parciais, mínimos ou totais. Os resultados demonstraram que houve uma melhora nos artigos publicados nos últimos anos, sob a ótica da aplicação e descrição, considerando as três fases: pré-análise, exploração do material e tratamento dos resultados. Alguns estudos utilizam a análise de conteúdo desprezando etapas principais, outros, apenas, citam o método na metodologia, mas não a aplicam na prática. As análises indicaram que 75% (39 de 52) dos artigos não deixam claras as etapas definidas por Bardin, além disso, 46% (24) dos trabalhos utilizaram um método analítico auxiliar em conjunto com a análise de conteúdo.

Concluiu-se que a observação dos atributos de melhoria, como propostos por Paswan e Young (2002), pode-se apresentar como um eficiente instrumento de gestão para as IES, auxiliando instituições, coordenadores de cursos e docentes na avaliação dos atributos determinantes para o ensino de disciplinas de Custos.
SENSIBLE HEAT TRANSFER ON ATMOSPHERIC-OCEANIC BOUNDARY IN THE OUTER AMBON BAY OF INDONESIA
Authors: Salamena Gerry Giliant
Published: July 2017

Analysis of air-sea temperatures and sensible heat flux was conducted to investigate heat transfer process on the atmospheric-oceanic boundary for the outer Ambon Bay. The analysis used SST data derived from both satellite product and in situ measurement using linear regression method, as well as meteorological data such as air temperature and wind speed during daytime. The goals of the current work were to evaluate the relationship between SST and air temperature in the outer Ambon Bay, and to investigate the variation of sensible heat flux in association with seasonal variability of the bay. The major findings were: 1) SST was predominantly lower than airtemperature, resulting in the dominance of negative feedback process on the atmospheric-oceanic boundary layer of the bay; 2) the seasonal SST variability was influenced by land heating and upwelling in the Banda Sea; 3) land heating resulted in large gradient of air-sea temperatures, whereas cooler upwelled waters exerted an opposite effect.
Comportamento hidrodinâmico e hidroquímico do sistema aquífero Barreiras-Jandaíra-Açu na área da fazenda Belém, oeste da Bacia Potiguar, CE
Authors: Braga Junior Maurilo Gonçalves , Melo José Geraldo de , Diniz Filho José Braz
Published: July 2017

A avaliação do comportamento hidrodinâmico e hidroquímico de aquíferos em áreas sob a influência da atividade petrolífera são essenciais para a proteção e gestão do recurso hídrico subterrâneo. Neste sentido, são analisadas neste trabalho as relações entre as cargas potenciométricas dos aquíferos Barreiras-Jandaíra e Açu na área de Fazenda Belém, oeste da Bacia sedimentar Potiguar estado do Ceará  e suas implicações na qualidade das águas subterrâneas. Foram consultados trabalhos regionais e estudos específicos na área de Fazenda Belém, acerca das características hidrodinâmicas e hidroquímicas das águas dos dois sistemas Aquíferos. Foram obtidos os dados hidroquímicos e de nível estático  e definidas as superfícies potenciométricas e os tipos iônicos dessas unidades aquíferas em diferentes períodos desde seu estado original, antes da influência da atividade petrolífera, até os dias atuais. O Aquífero Açu apresentou um rebaixamento da ordem de até 110m, enquanto o sistema Aquífero Barreiras-Jandaíra sobrejacente, apresentou somente pequenas variações da ordem de 2 a 4m. Os dados hidroquímicos permitem afirmar que na área de estudo, as águas armazenadas no Aquífero Barreiras-Jandaíra são classificadas como do tipo cloretada-bicarbonatada – sódica–cálcica e as águas armazenadas no Aquífero Açu são classificadas como do tipo bicarbonatada-cloretada – sódica. Foi possível concluir que os aquíferos Açu e Barreiras–Jandaíra correspondem a sistemas aquíferos individualizados. O fato de que o rebaixamento do nível estático verificado no Aquífero Açu, não afetou as cargas potenciométricas do Aquífero Barreiras-Jandaíra e os tipos iônicos distintos definidos para os dois sistemas aquíferos, sugere a existência de um isolamento hidráulico e a inexistência de mistura de águas entre os mesmos, desde seu estado original até o presente.

Authors: Silva Renato Aguiar , Da Hora Henrique Rego Monteiro , Oliveira Vicente De Paulo Santos
Published: July 2017

Na cidade de São Francisco de Itabapoana – RJ – Brasil, assim como em outras regiões do País, a falta de abastecimento na zona urbana e rural tem sido solucionada muito mais através da perfuração de poços que da adoção de medidas gerenciais capazes de reduzir as perdas e aperfeiçoar os sistemas existentes. O mapeamento da qualidade da água subterrânea consumida nas localidades de São Francisco de Itabapoana foi realizado através do uso de ferramenta Sistemas de Informações Geográficas - SIG, onde se verificou a sua conformidade com os padrões de potabilidade para água de consumo humano. Para isso, foram estudadas vinte e uma localidades e analisados parâmetros físico-químicos (potencial Hidrogeniônico (pH), turbidez, cloro total, salinidade) e parâmetros microbiológicos (coliformes totais e coliformes termotolerantes). Os resultados revelaram uma potencial contaminação por coliformes totais e termotolerantes em grande parte do município e que alguns parâmetros físico-químicos estão fora do padrão de qualidade da água de consumo humano em muitas localidades. Os resultados obtidos indicam uma precariedade no saneamento urbano e rural do município.
Increasing Block Tariffs in the Water Sector – An Interpretation in Terms of Social Preferences
Authors: Meran Georg , von Hirschhausen Christian
Published: July 2017

Many developing countries around the world apply progressive water tariffs, often structured in the form of discretely increasing block tariffs (IBTs). These tariffs have been criticized in the welfare economic literature due to their perceived inefficiency: many of the prices charged under IBTs do not correspond to marginal costs and thus violate the principle of allocative efficiency. In this paper we explore an alternative interpretation of the widespread use of IBTs, in terms of social preferences and fairness considerations. For this, we rely on an extension of the Fehr, E., and K. Schmidt (1999. “A Theory of Fairness, Competition, and Cooperation.”Quarterly Journal of Economics114: 817–868.) utility function, including inequality aversion, to which we add another parameter representing a reference for redistribution which reflects a societal preference to correct for income difference perceived as unfair. Additionally, the model includes a variable on household size, finding that, as poor households are on average larger, a simple IBT tariff disregarding household size may not be “fair”.
Retrofitting the Low Impact Development Practices into Developed Urban areas Including Barriers and Potential Solution
Authors: Shafique Muhammad , Kim Reeho
Published: July 2017

Low impact development (LID)/green infrastructure (GI) practices have been identified as the sustainable practices of managing the stormwater in urban areas. Due to the increasing population, most of the cities are more developing which results in the change of natural area into impervious areas (roads, buildings etc.). Moreover, urbanization and climate change are causing many water-related problems and making over cities unsafe and insecure. Under these circumstances, there is a need to introduce new stormwater management practices into developed cities to reduce the adverse impacts of urbanization. For this purpose, retrofitting low impact development practices demands more attention to reduce these water-related problems and trying to make our cities sustainable. In developed areas, there is a little space is available for the retrofitting of LID practices for the stormwater management. Therefore, the selection of an appropriate place to retrofitting LID practices needs more concern. This paper describes the successfully applied retrofitting LID practices around the globe. It also includes the process of applying retrofitting LID practices at the suitable place with the suitable combination. Optimal places for the retrofitting of different LID practices are also mentioned. This paper also highlights the barriers and potential solutions of retrofitting LID practices in urban areas.
A Novel Hybrid Technique to Predict the Lithium-Ion Battery’s Behavior and Estimate the Intern Impedance
Authors: Elabadine Dahmane Zine , Ali Malek , Mourad Haddadi
Published: July 2017

A battery model that predicts the electrical performance with high accuracy is vital for circuit designing to control the battery usage and improve its runtime and safety in electrical systems such as electric vehicle (EV). In this paper, a relatively simple equivalent circuit based model is developed for modeling the performance of lithium ion batteries used in automotive applications. The model’s strategy adopted for characterization of the internal parameters is based on two main techniques: one is the electrochemical impedance spectroscopy (EIS) tests, where comparable circuit is set up as per EIS test perceptions and the other is the current pulses technique, this latter is carried out using a proposed current pulses profile. The extracted parameters are scheduled on the state-of-charge, temperature, and current direction. The comparison between experiment and simulation results demonstrates that with the optimally extracted performance parameters, the proposed approach can accurately predict the performance of differents batteries of various sizes, capacities, and materials. Eventually, this simple battery model can serve as a robust and reliable tool for predicting the battery’s I-V performance in electrified vehicle battery management systems.
Code-switching in the media: Identity negotiations in a Gujarati diaspora radio program
Authors: Zipp Lena
Published: July 2017

This article aims to explore the construction of post-diasporic, hybrid local identities in communicative practices of the younger British Gujarati community. It focuses on the host of a popular BBC Asian Network radio show as a prominent voice of this community, who simultaneously embodies and creates linguistic community values through the use of Gujarati-English code-switching. In doing so, it highlights the role of the media in shaping a space for the linguistic negotiation of local and transnational influences. On a methodological level, the article argues for the combination of data from different domains in the context of transnational identity negotiations, such as linguistic behavior, narrative language biographies, private and public meta-linguistic commentary, indications of language status and attitudes towards alternating language use.
Quintilian on “grammatical homonymy”: The linguistic sensibility of a Roman lawyer
Authors: Uría Javier
Published: July 2017

After defining grammatical (as opposed to lexical) homonymy as concerning either inflection or the conflict between different parts of speech, attention is paid to those contexts in which Varro and Quintilian dealt with processes falling under that concept. The paper remarks on the acute distinction Quintilian seems to make between lexical and grammatical homonymy by dealing with the former in relation to rhetoric and the latter within the grammatical chapters of book I. The similarity of Quintilian’s approach to homonymy is then shown with the use Apollonius Dyscolus would later make of the term

O presente texto busca discutir a importância dos museus de Arqueologia para a sociedade brasileira, evidenciando as transformações que lhe vêm sendo implementadas, a partir de questionamentos nascidos dentro do campo da Museologia, da Arqueologia e da História, como resposta às mudanças por que tem passado a sociedade brasileira nas últimas décadas. De forma a evidenciar tais transformações busca-se recorrer à revisão histórica dos diversos contextos político-culturais do país, destacando as transformações sociais em contexto pós-ditatorial. As políticas inclusivas e o surgimento de novos atores são, assim, relacionados aos questionamentos emergidos dos próprios campos científicos, possibilitando a compreensão do papel exercido por esses museus na contemporaneidade.
De caballos voladores y formidables tempestades: Experiencias religiosas del paisaje misional en Esteco (s. XVI-XVIII) y Tierra del Fuego (s. XIX-XX)
Authors: Marschoff María , Salerno Melisa A.
Published: July 2017

Neste  trabalho,  analisamos  a  experiência  religiosa  de paisagem  de  dois  grupos  missionários  em  contextos coloniais historicamente diferentes. O primeiro grupo é o dos jesuítas,  que  viajaram,  viveram  e  fundaram  reduções  na jurisdição da cidade de Esteco (norte da Argentina) desde o final do século XVI até o principio do século XVIII. O segundo, corresponde aos missionários salesianos, que exploraram e estabeleceram missões na Tierra del Fuego (sul da Argentina e Chile)  desde  o  final  do  século  XIX  até  meados  do  século XX. No decorrer de seus trabalhos, ambas ordens produziram uma série de registros  sobre eventos  percebidos geralmente como  conjunturais  para  suas  vidas: “visões” da paisagem antes de chegar ao lugar, fenômenos naturais  considerados  catastróficos  (como  tempestades  e terremotos de grande magnitude), situações de risco pessoal (como  estar  perdido  na  região   ou  encontrar-se  sem recursos),  epidemias  e  pestes,  etc. Considerando   essas referências,  nos perguntamos sobre  a  relação  entre  a  materialidade  das paisagens e as experiências religiosas. Especificamente, nos indagamos como as paisagens inicialmente desconhecidaspara os missionários foram mudando sua“qualidade” religiosa ao longo da labor evangelizadora sobre os indígenas.
How Much Group is Necessary? Group-To-Individual Transfer in Estimation Tasks
Authors: Stern Alexander , Schultze Thomas , Schulz-Hardt Stefan
Published: July 2017

G-I transfer denotes an increase in individual performance due to group interaction, for example, because of acquiring certain skills or knowledge from the other group members. Whereas such G-I transfer has been successfully shown for problem-solving tasks, evidence for G-I transfer on quantitative estimation tasks is scarce. We address this research gap with a focus on how often a group has to interact in order to fully exploit the benefit of this learning effect. Results from two experiments support the idea that a single group interaction is sufficient to induce a stable G-I transfer, which reduces group members’ metric error. Smaller metric errors indicate that people improved their representation of the correct upper and lower boundaries, or what range of values is plausible. In contrast to nominal groups, both members of continuously interacting groups and members of groups with only one initial interaction exhibited stable G-I transfer, and the size of this transfer did not significantly differ between the latter two conditions. Furthermore, we found evidence for differential weighting of group members’ individual contributions that goes beyond sheer individual capability gains under certain circumstances, namely in tasks with a population bias.
Spontaneous reossification of the sella in transsphenoidal reoperation associated with strontium ranelate

Published: July 2017

Spontaneous reossification of the sellar floor after transsphenoidal surgery has been rarely reported. Strontium ranelate, a divalent strontium salt, has been shown to increase bone formation, increasing osteoblast activity. We describe an unusual case of a young patient with Cushing’s disease who was treated with strontium ranelate for low bone mass who experienced spontaneous sellar reossification after transsphenoidal surgery. A 21-year-old male presented with Cushing’s features. His past medical history included delayed puberty diagnosed at 16 years, treated with testosterone for 3 years without further work-up. He was diagnosed with Cushing’s disease initially treated with transsphenoidal surgery, which was not curative. The patient did not come to follow-up visits for more than 1 year. He was prescribed strontium ranelate 2 g orally once daily for low bone mass by an outside endocrinologist, which he received for more than 1 year. Two years after first surgery he was reevaluated and persisted with active Cushing’s disease. Magnetic resonance image revealed a left 4 mm hypointense mass, with sphenoid sinus occupation by a hyperintense material. At repeated transsphenoidal surgery, sellar bone had a very hard consistency; surgery was complicated and the patient died. Sellar reossification negatively impacted surgery outcomes in this patient. While this entity is possible after transsphenoidal surgery, it remains unclear whether strontium ranelate could have affected sellar ossification.

Learning points:

Delayed puberty can be a manifestation of Cushing’s syndrome. A complete history, physical examination and appropriate work-up should be performed before initiating any treatment.

Sellar reossification should always be taken into account when considering repeated transsphenoidal surgery. Detailed preoperative evaluation of bony structures by computed tomography ought to be performed in all cases of reoperation.

We speculate if strontium ranelate may have affected bone mineralization at the sellar floor. We strongly recommend that indications for prescribing this drug should be carefully followed.
Die methodischen probleme der ungarischen landnahmezeitlichen Forschung. Die Gräberfelder
Authors: Révész László
Published: July 2017

Since the 1960’s two approaches mainly based on ethnical and social differences have been applied in the course of the analysis of the 10th–11th century cemeteries of the Carpathian Basin. However, the social classification of certain cemeteries is problematic. The division considered applicable to the entire 10th–11th century settlement area (tribal and clan aristocracy — middle class — commoners) does not stand its ground anymore; the cemeteries known today cannot be interpreted as their direct archaeological projections. Families or larger communities of equal status or the same social group could have been greatly different regarding their appearance, inheritance, wealth, agricultural practices, and thus their archaeological appearance. The division of sites on ethnical grounds is a similar issue. The new approach focuses on the duration of the cemeteries’ usage, and in connection with this, the number of their graves. I illustrate this with a settlement historical image outlined by the review of the find material of the Tisza—Maros—Körös interfluve. I observed 133 sites in this region which were mostly fractional, ranging from a few graves to dozens of burials. Taking all these aspects into consideration, hereunder I only have an opportunity to briefly outline a picture, according to which the cemeteries of this region are arranged in six larger blocks. Their characteristics are partly different from each-other.
Simultaneous quantification of related substances of ezetimibe and simvastatin in combined dosage form using a novel stability-indicating liquid chromatographic method

Published: July 2017

A novel, simple, robust, and rapid reversed-phased high-performance liquid chromatographic method has been developed for the separation and quantitative determination of the related substances of ezetimibe and simvastatin in combined dosage forms. Successful separation of the drug from the process-related impurities and degradation products formed under stress conditions was achieved on Inertsil ODS-3V (150 × 4.6 mm, 5.0 μm) column. The gradient liquid chromatography (LC) method employs solution A and solution B as mobile phase. The solution A contains 0.1% orthophosphoric acid solution in water, and solution B contains 0.1% orthophosphoric acid solution in acetonitrile. Flow rate was monitored at 2.0 mL/min, and the ultraviolet (UV) detection, at 238 nm. In forced degradation studies, the effect of acid, base, oxidation, UV light, and temperature was investigated, showing that good resolution between the peaks corresponds to process-related impurities and degradation products from both analyte. The performance of the method was validated according to the present International Conference on Harmonization (ICH) guidelines for specificity, limit of detection, limit of quantification, linearity, accuracy, precision, ruggedness, and robustness. To the best of our knowledge, a rapid LC method, which separates all the impurities of ezetimibe and simvastatin in combined dosage forms, disclosed in this investigation was not published elsewhere.

Transitions in Prognostic Awareness Among Terminally Ill Cancer Patients in Their Last 6 Months of Life Examined by Multi-State Markov Modeling
Authors: Hsiu Chen Chen , Wen Fur-Hsing , Hou Ming-Mo , Hsieh Chia-Hsun , Chou Wen-Chi , Chen Jen-Shi , Chang Wen-Cheng , Tang Siew Tzuh
Published: July 2017

Background

Developing accurate prognostic awareness, a cornerstone of preference-based end-of-life (EOL) care decision-making, is a dynamic process involving more prognostic-awareness states than knowing or not knowing. Understanding the transition probabilities and time spent in each prognostic-awareness state can help clinicians identify trigger points for facilitating transitions toward accurate prognostic awareness. We examined transition probabilities in distinct prognostic-awareness states between consecutive time points in 247 cancer patients’ last 6 months and estimated the time spent in each state.

Methods

Prognostic awareness was categorized into four states: (a) unknown and not wanting to know, state 1; (b) unknown but wanting to know, state 2; (c) inaccurate awareness, state 3; and (d) accurate awareness, state 4. Transitional probabilities were examined by multistate Markov modeling.

Results

Initially, 59.5% of patients had accurate prognostic awareness, whereas the probabilities of being in states 1–3 were 8.1%, 17.4%, and 15.0%, respectively. Patients’ prognostic awareness generally remained unchanged (probabilities of remaining in the same state: 45.5%–92.9%). If prognostic awareness changed, it tended to shift toward higher prognostic-awareness states (probabilities of shifting to state 4 were 23.2%–36.6% for patients initially in states 1–3, followed by probabilities of shifting to state 3 for those in states 1 and 2 [9.8%–10.1%]). Patients were estimated to spend 1.29, 0.42, 0.68, and 3.61 months in states 1–4, respectively, in their last 6 months.

Conclusion

Terminally ill cancer patients’ prognostic awareness generally remained unchanged, with a tendency to become more aware of their prognosis. Health care professionals should facilitate patients’ transitions toward accurate prognostic awareness in a timely manner to promote preference-based EOL decisions.

Aprendizaje de las matemáticas a través de la modelación matemática en un medio sociocultural ligado a la teoría de la actividad
Authors: Hitt Fernando , Quiroz Rivera Samantha
Published: July 2017

La investigación en torno a la modelación matemática ha llevado al cambio de currículo en diferentes sistemas educativos en el mundo. Estudios recientes han mostrado como variable importante en la modelación matemática el proceso de comunicación entre los estudiantes para la resolución de tareas complejas. El presente estudio tiene como propósito comprender cómo estos procesos de comunicación apoyan el aprendizaje de las matemáticas en la resolución de situaciones problema. Aplicando la teoría de la actividad, se analizaron las representaciones de cuatro estudiantes acerca de la noción de covariación, así como su evolución a través del uso de una metodología que privilegia el debate científico y la autorreflexión. Los resultados muestran que las representaciones intuitivas de los estudiantes tienen un carácter funcional y espontáneo, y se pueden modificar a través de la interacción y el diálogo dentro de un trabajo en equipo. Con ello se promueve la equidad en la construcción del conocimiento.

Historias de familia. El marco ampliado de las historias de vida
Authors: Álvarez Vargas Cristina , Amador Baquiro Carlos
Published: July 2017

El artículo explora qué es y cómo fue usado el método historias de familia (Bertaux, 1995; Miller, 2007) en la investigación doctoral “Experiencias de crianza en contextos de conflicto armado en Colombia”. El texto expone cómo se ubica este método en los debates contemporáneos sobre investigación cualitativa y su articulación epistemológico-metodológica. Luego muestra la relación de este método con la tradición biográfico-narrativa de la investigación social. Después, explica cómo surgió el método a partir de lo que Bertaux (1995) llama historias de familia desde la genealogía social comparada y comentada (gscc). Más adelante, describe los criterios conceptuales y procedimentales de las historias de familia a partir del modelo sugerido por Miller (2007). Por último, se incluyen algunos ejemplos de la investigación doctoral que ilustran el uso del método.
Prácticas educativas en movimientos sociales de América Latina
Authors: Torres Carrillo Alfonso
Published: July 2017

El artículo presenta un análisis de cuatro propuestas educativas gestadas por movimientos sociales y procesos populares en América Latina. Tomando como referente la sistematización de cada una de estas, se hace una lectura transversal de los sentidos y prácticas más significativos con respecto a algunas dimensiones de su acción educativa, tales como su organicidad e identidad política, sus sujetos educativos, sus influencias pedagógicas, finalidades formativas, contenidos curriculares, metodologías de trabajo, producción de conocimiento y sostenibilidad. Finalmente, se hace un balance reflexivo sobre las tensiones y los desafíos de las prácticas educativas en los movimientos sociales.
El lenguaje docente como una forma de exclusión educativa en las aulas universitarias
Authors: Chévez Ponce Florlenis , Astudillo Torres Martha Patricia , Artavia Medrano Álvar
Published: July 2017

El artículo presenta la opinión que tienen los estudiantes de la Licenciatura en la Enseñanza de los Estudios Sociales y la Educación Cívica de la Universidad de Costa Rica sobre el lenguaje que utiliza el profesorado en los diferentes cursos que reciben. Se utilizó la técnica de grupos de discusión con el fin de resaltar y contrastar las diversas opiniones del estudiantado en relación con las formas de comunicación percibidas en la cotidianidad del ambiente del aula. A partir de los hallazgos, se plantea la necesidad de que el personal docente reflexione acerca del lenguaje que emplea, de manera que permita una participación del estudiantado con mayor libertad en la interacción propia del quehacer cotidiano del aula.
Sistemas digestório, respiratório e circulatório Humanos em livros didáticos de Biologia de Ensino Médio

Published: July 2017

O livro didático é um instrumento muito utilizado em sala de aula, constituindo uma fonte de consulta para alunos e professores. Erros conceituais neles contidos podem comprometer uma cadeia de conhecimento culminando nas concepções equivocadas apresentadas por muitos alunos ao fim do Ensino Médio. Assim, torna-se necessário a análise de tais livros. O objetivo deste estudo é avaliar a abordagem do sistema digestório, respiratório e circulatório em livros didáticos de Ensino Médio. Para tal, foram analisados quatro livros dos anos 2013, 2010, 2009 e 2006, obtidos junto à biblioteca de uma escola particular de Ijuí (RS). De modo geral, todos apresentaram várias falhas ao trabalhar os conceitos, destacando Vitorino (2009) devido ao resumo exagerado das informações. Algumas obras apresentaram contradições e analogias que possibilitam concepções dúbias. Ao fim deste trabalho, destaca-se que é necessária que os professores façam uma análise prévia dos livros didáticos adotados, a fim de que possam fazer os arranjos, discussões e complementações necessárias para evitar a repetição de erros conceituais.
Análisis de las concepciones de los alumnos en torno a una experiencia sobre desarrollo y crecimiento de la Drosophila melanogaster
Authors: Ruiz Sánchez Gerardo , Martínez Murillo Jhon Jairo , Ibáñez Córdoba Sandra Ximena , Chona Duarte Guillermo
Published: July 2017

En esta investigación se analizan las concepciones presentes en el discurso de alumnos de octavo grado del Colegio Ciudad de Bogotá, Institución Educativa Distrital, en torno al desarrollo y el crecimiento, a través de la experiencia con el ciclo de vida de Drosophila melanogaster. La investigación se dividió en dos momentos: en el primero, a través de una encuesta, se identificaron las concepciones iniciales de los alumnos, y en el segundo, los alumnos, junto con el docente, trabajaron in situ el ciclo de vida del insecto objeto de estudio. Las interacciones discursivas fueron grabadas en audios, transcritas y categorizadas; posteriormente, se las analizó desde el nivel semántico de acuerdo con los planteamientos de Teun van Dijk (1985). Con los significados asignados, se establecieron implicaciones sobre la enseñanza del contenido de estudio en ciencias naturales. El método de la investigación consideró: la perspectiva cualitativa-interpretativa, el enfoque del análisis del discurso y el empleo de las técnicas de codificación abierta —categorización— para el primer momento, y de análisis semántico, para el segundo momento. El proceso investigativo facilitó que los alumnos resignificaran sus saberes mediante la experiencia de aula; es decir, sus concepciones iniciales fueron transformándose en la medida en que confrontaban el ciclo de vida de Drosophila melanogaster con la información adquirida a través de la interacción discursiva.
Desenhando com palavras: a terra viva do sertão euclidiano
Authors: Simões Rodrigo Lemos , Rosa Lúcia R. Lucas da
Published: July 2017

Este artigo examina a geopoética contida na narrativa euclidiana a respeito do sertão nordestino, tendo como base o livro Os sertões. Obra original e inquietante foi responsável por trazer outro olhar sobre o interior do país, apresentando aos seus leitores um Brasil profundo onde as utopias de progresso e civilização encontravam a resistência tanto nos homens como na terra. Homem de letras e ciências, designado para acompanhar o episódio final protagonizado pelo exército nacional que combatia os sertanejos na vila de Canudos, interior da Bahia, acabou por deparar-se com questões sociais relacionadas ao abandono por parte do Estado e as intempéries da terra. Crítico e reflexivo teve que refazer muitos dos seus conceitos sobre as transformações por que passava o Brasil naquele período, em especial da vida em locais onde o meio físico se apresenta de forma tão intensa como é o caso do sertão baiano. Vista de forma integral o cenário descrito pelo autor vai além da aridez com que se construiu ao longo dos anos a imagem feita sobre o sertão e o sertanejo, pintando com palavras a transformação da natureza no nordeste do país.
Os Conselhos Municipais de Educação no âmbito do planejamento decenal estadual da educação2014-2024 no Brasil
Authors: Oliveira Rosimar De Fátima , De Souza Donaldo Bello
Published: July 2017

O presente artigo visa ao exame de como os Conselhos Municipais de Educação (CMEs) são tratados no âmbito do planejamento estadual da educação, tomando por base empírica os Planos Estaduais de Educação relativos ao Plano Nacional de Educação 2014-2024, que tenham sido efetivamente transformados em norma jurídica até o mês de dezembro de 2016. As análises evidenciam a existência, por um lado, de uma intensa repercussão nesses documentos da responsabilização atribuída pelo PNE 2014-2024 aos poderes executivos estaduais e municipais pelo funcionamento e autonomização dos CMEs, e, por outro, de uma forte atribuição de competências articuladas aos processos participativos e à fiscalização.
Asymptotic Behaviors of Wronskians and Finite Asymptotic Expansions in the Real Domain - Part I: Scales of Regularly- or Rapidly-Varying Functions
Authors: Granata Antonio
Published: July 2017

In a previous series of papers we established a general theory of finite asymptotic expansions in the real domain for functions f of one real variable sufficiently-regular on a deleted neighborhood of a point x0 ∈ R, a theory based on the use of a uniquely-determined linear differential operator L associated to the given asymptotic scale and wherein various sets of asymptotic expansions are characterized by the convergence of improper integrals involving both the operator L applied to f and certain weight functions constructed by means of Wronskians of the given scale. Very special cases apart, Wronskians have quite complicated expressions and unrecognizable asymptotic behaviors; however in the present work, split in two parts, we highlight some approaches for determining the exact asymptotic behavior of a Wronskian when the involved functions are regularly- or rapidly-varying functions of higher order. This first part contains: (i) some preliminary results on the asymptotic behavior of a determinant whose entries are asymptotically equivalent to the entries of a Vandermonde determinant; (ii) the fundamental results about the asymptotic behaviors of Wronskians involving scales of functions all of which are either regularly (or, more generally, smoothly) varying or rapidly varying of a suitable higher order. A lot of examples and applications to the theory of asymptotic expansions in the real domain are given.

Authors: Tiwari Vikalp , Gudsurkar Gopal
Published: July 2017

Background: Assessment of oral hypoglycaemic activity of water soluble extract of Aloe vera and its interaction with Glipizide in Alloxan induced diabetic Wistar rats.Methods: Under standard condition of testing, alloxan induced diabetic rats were kept in fasting state of 8 hours and then glucose in dose of 1gm/kg was given PO by feeding tube. There after water soluble extract of aloe vera in dose of 200mg/kg BW dissolves in 1ml of Distilled water (DW) to test group 1, Glipizide in dose of 2.5mg/kg BW dissolved in 1ml DW was given to standard group. Test group 2 received combination of Aloe vera 200mg/kg BW and Glipizide in dose of 2.5mg/kg BW dissolved in 1ml Dw. Control group received 1ml of Distilled water. Blood sugars levels of all Rats in each group were checked with Glucometer.Results: Clinically and statistically significant glucose lowering effect was observed in groups administered with Aloe vera and better results were observed in group receiving Aloe vera and Glipizide combination.Conclusions: Water soluble extract of aloe vera has significant hypoglycaemic activity and the results showed that co-administration of Aloe vera and Glipizide has superior hypoglycaemic activity compared to Aloe vera and Glipizide given Individually.
The genetic aspect and morphological appearance of achondrogenesis
Authors: Edy Parwanto Mauritius Lambertus
Published: July 2017

Achondrogenesis (ACG) is a number of disorders that are the most severe form of congenital chondrodysplasia characterized with bones and cartilage malformation. Generally, characteristic of ACG is a small body, short limbs, and other skeletal abnormalities. As a result of infants with ACG their serious health problems, usually born prematurely, are stillborn, or die shortly after birth from respiratory failure. Currently 3 type variants of ACG such as ACG-1A, ACG-1B and ACG-2. ACG-1A appears to be autosomal recessive (AR), with thyroid hormone receptor interactor 11 (TRIP11) gen mutation, while ACG1B also appears to be AR, with diastrophic dysplasia sulfate transporter or DTDST (SLC26A2) gen mutation. ACG-2 is caused by autosomal dominant (AD), with type 2 collagen (COL2A1) gen mutation. ACG-1A had characterizid such as physis abnormal, vertebral bodies with unossified or smal and oval, skull poorly ossified, periodic acid–Schiff (PAS) stain positive chondrocyte inclusions finding in long bones. ACG-1B had physis abnormal, vertebral bodies with unossified or smal and oval, skull ossified, perichondrocyte collagen rings finding in long bones. ACG-2 also had physis abnormal, metaphyseal cupping, vertebral bodies with unossified or small and oval, enlarged chondrocyte lacunae.

Existence of Hukuhara Differentiability of Fuzzy-Valued Functions
Authors: Pirzada U. M. , Vakaskar D. C.
Published: July 2017

In this paper, we discuss existence of Hukuhara differentiability of fuzzy-valued functions. Several examples are worked out to check that fuzzy-valued functions are one time, two times and n-times H-differentiable. We study the effects of fuzzy modelling on existence of Hukuhara differentiability of fuzzy-valued functions. We discuss existence of gH-differentiability and its comparison with H-differentiability.
