Wavelet Analysis of DFIT Data to Identify Fracture Closure Parameters
Authors: Unal Ebru , Siddiqui Fahd , Soliman Mohamed Y. , Dindoruk Birol
Published: January 2019

Due to the shift from conventional reservoirs towards unconventional, ultra-low permeability reservoirs in the last decade, Diagnostic Fracture Injection Test (DFIT) has become one of the dominant and economically practical pressure transient tests. It is crucial to analyze and interpret DFIT data correctly to obtain essential fracture design and reservoir parameters. This study presents the application of wavelet analysis to DFIT falloff pressure data to determine fracture closure pressure and time, to ultimately improve the overall efficiency of hydraulic fracturing designs.

In this study, DFIT pressure is treated as a non-stationary signal and analyzed by one of the signal processing techniques which is wavelet transformation. The purpose of signal analysis is to extract relevant information from a signal by transforming it. Firstly, the signal is transformed into wavelet domain by Discrete Wavelet Transformation (DWT) to calculate high-frequency wavelet coefficients (details), then change-point detection technique is applied to distinguish major changes within the coefficients trend to determine fracture closure pressure and time.

DFIT pressure decline data from different wells were analyzed by wavelet transformation. Detail coefficient demonstrates different patterns depending on the formation analyzed and near wellbore activities. This is expected because wavelet analysis is sensitive to any physical changes within the system. From the amplitude changes of the coefficients, wavelet tool demonstrates the fracture closure as a continuing process.

Because wavelet is sensitive to changes in the system, it detects the fracture closure unambiguously by amplitude change, as compared to slope changes in other conventional methodologies. A comparison with some of the most commonly used diagnostic techniques, conventional log-log diagnostic plot, square root time, G-function and its derivative analysis are also provided in this study.

There have been several publications discussing various techniques analyzing DFIT pressure decline in unconventional formations and yet there is relatively high uncertainty in before-closure-analysis. However, this methodology is more sensitive to fundamental changes in the system, so application in detecting closure pressure and time decreases the uncertainty compared to other conventional tangential methodologies.
Optimization of Plug-and-Perf Completions for Balanced Treatment Distribution and Improved Reservoir Contact
Authors: Yi Sophie , Wu Chu-Hsiang , Sharma Mukul
Published: January 2019

Heel-dominated treatment distribution among multiple perforation clusters is frequently observed in plug-and-perf stages, causing small propped surface areas, suboptimal production, and unexpected frac-hits.

A multi-fracture simulator with a novel wellbore fluid and proppant transport model is applied to quantify treatment distribution among multiple perforation clusters in a plug-and-perf operation. A simulation Base Case is set up based on a field treatment design with four clusters. Simulation results show that the two toe-side clusters screened out early in the treatment and the two heel-side clusters were dominant. The simulated proppant placement is consistent with DAS observations.

The impact of different perforating strategies and pumping schedules on final treatment distribution is investigated. Two criteria are defined that quantify the proppant distribution and fracture area: the Weighted Average (WA) and Standard Deviation (SD) of the final fluid and proppant distribution, as well as the Hydraulic and Propped Surface Area (HSA and PSA) of the created fractures. An optimum plug-and-perf design is defined as one that minimizes the SD of the treatment distribution among perforation clusters and maximizes the PSA.

Both perforating strategy and pumping schedule are found to affect the final treatment distribution significantly, and uniform treatment distribution is shown to create more PSA. Fewer perforations-per-cluster were found to promote uniform fluid and proppant placement. Other helpful strategies include reducing the number of perforations near the heel, using small, lightweight proppant and so on. The stress shadow effect is accounted for using the Displacement Discontinuity Method (DDM) and was found to play a smaller role than perforation friction and proppant inertia in most cases.

An automated process is developed to optimize plug-and-perf completion design with multiple decision variables using a Genetic Algorithm. Thirteen parameters are optimized simultaneously. The optimal design solution creates an almost even treatment distribution and more than doubled the PSA compared to the Base Case.

The multi-fracture model presented in this paper provides a way to quantify fluid and proppant distribution for any perforating strategy and pumping schedule and provides more insights of the physics relevant to plug-and-perf treatment distribution. The perforation and pumping schedule recommendations presented in this paper provide directional guidance to design a fracturing job of balanced treatment distribution and large propped surface area.

An experimental pulsed-neutron logging-while-drilling (LWD) tool is currently under field test. The tool provides a suite of nuclear measurements that include neutron porosity, thermal neutron capture cross section (i.e. sigma), pulsed-neutron density and the relative abundance of certain elements (e.g., calcium, silicon, iron, sulfur, etc.) that are used to calculate mineralogy. The tool provides azimuthal measurements in real time that are useful for geosteering applications.

Use of a pulsed-neutron source eliminates the need for radioactive-chemical sources that are used in conventional nuclear LWD tools. This results in increased wellsite safety and efficiency. Procedures and equipment required for radioactive-source handling, storage and retrieval are also eliminated.

The experimental LWD tool is the result of a joint collaboration that began in 1995 between the Japan National Oil Corporation and Schlumberger. The primary goal of the tool is to demonstrate feasibility of pulsed-neutron measurements in the hostile LWD environment.

Introduction

An experimental pulsed-neutron LWD tool has been developed that has successfully logged several test wells. The prototype tool represents a merging of pulsed-neutron wireline measurements with LWD measurement technology.

The applications of pulsed-neutron measurements for formation evaluation are well established. Pulsed-neutron wireline tools are used to determine water saturation, neutron porosity and formation mineralogy in both open and cased holes.

In addition to the rich variety of measurements, pulsed-neutron technology eliminates the radioactive-chemical sources used in conventional nuclear tools. Source-storage pits, transport shields, loading shields, collar shields and handling tools are therefore not required. Transportation logistics, wellsite safety and wellsite efficiency are all improved.

Analysis of changes in drought and terrestrial water storage in the Tarim River Basin based on principal component analysis
Authors: Xia Jun , Yang Peng , Zhan Chesheng , Qiao Yunfeng
Published: January 2019

Drought is a widespread natural hazard. In this study, the potential factors affecting spatiotemporal changes of drought in the Tarim River Basin (TRB), China, were investigated using the empirical orthogonal function (EOF) and multiple hydro-meteorological indicators such as the standardized precipitation index (SPI), standardized soil moisture index (SSI), and terrestrial water storage (TWS). The following major conclusions were drawn. (1) Inconsistent variations between SPIs/SSIs and TWS in the TRB indicate a groundwater deficit in 2002–2012. (2) The results of EOF indicate that soil moisture in the TRB was significantly affected by precipitation. However, the variations between the EOFs of SSIs and those of TWS were not identical, which indicates that soil water had less effect on TWS than groundwater. (3) Drought evaluations using SPI and SSI showed that a long drought duration occurred over a long accumulation period, whereas a high frequency of drought was related to a short accumulation period. (4) Hydrological features related to extreme soil moisture conditions in the TRB could also be influenced by the El Niño–Southern Oscillation. The findings of this study are significant for use in drought detection and for making water management decisions.
Degradation of malachite green by a pulsed light/H2O2 process
Authors: Navarro Patricia , Zapata Jean Pier , Gotor Gemma , Gonzalez-Olmos Rafael , Gómez-López Vicente M.
Published: January 2019

Pulsed light (PL) is a type of photonic technology characterized by intense short light pulses that enhance the speed of photochemical reactions, and which might be useful as light source in advanced oxidation processes. This work aimed to test PL as light source for the degradation of the dye malachite green (MG) by combining PL with H2O2. To this end, the effect of dye and H2O2 concentrations and pH on the degradation rate of MG was studied and a degradation pathway was proposed. Dye degradation followed a pseudo-first order kinetics; it increased with low initial dye concentration, high H2O2 concentration and low pH. Complete decolourization was achieved after 35 light pulses (75 J/cm2), with a degradation rate of 0.0710 cm2/J. The degradation was initiated by the attack of hydroxyl radicals to the central carbon of MG generating 4-(dimethylamino)benzophenone (DLBP) followed by the addition of hydroxyl radicals to the non-amino aromatic ring of DLBP and the demethylation of the amino group. Results indicate that PL technology has potential to be implemented to decrease the environmental impact of dyeing industries.
Soybean Peptide QRPR Activates Autophagy and Attenuates the Inflammatory Response in the RAW264.7 Cell Model
Authors: Pan Fengguang , Wang Lin , Cai Zhuanzhang , Wang Yinan , Wang Yanfei , Guo Jiaxin , Xu Xiangyu , Zhang Xiaoge
Published: January 2019

Background:

There are few studies on the autophagy and inflammatory effects of soy
peptides on the inflammatory cell model. Further insight into the underlying relationship of soybean
peptides and autophagy needs to be addressed. Therefore, it is worthwhile investigating the possible
mechanisms of soybean peptides, especially autophagy and the inflammatory effects.

Objective:

In this study, we used a RAW264.7 cell inflammation model to study the inhibitory effect
and mechanism of soybean peptide QRPR on inflammation.

Methods:

We used LPS-induced inflammation model in RAW264.7 cells to study the inhibitory
effect and mechanism of soybean peptide QRPR on inflammation. First, Cell viability was determined
by cell activity assay. Subsequently, the concentrations of the inflammatory cytokines IL-6
and TNF-α were measured by ELISA. IL-6, TNF-α, Beclin1, LC3, P62, PIK3, AKT, p-AKT, pmTOR
and mTOR protein expression were detected by western-blot. PIK3, AKT and mTOR gene
expression level were quantified by quantitative real-time PCR. Double-membrane structures of
autophagosomes and autolysosomes were observed by transmission electron microscopy. The
PI3K/AKT/mTOR signaling pathway in LPS-induced RAW264.7 cells was speculated when the
autophagy was activated.

Results:

The results showed that QRPR activates autophagy in the inflammatory cell model and
that the inhibitory effect of QRPR on inflammation is reduced after autophagy was inhibited. Western-
blot and real-time PCR results indicated that QRPR activates autophagy in LPS-induced
RAW264.7 cells by modulating the PI3K/AKT/mTOR signaling pathway, and it shows a significant
time dependence.

Conclusion:

This study indicated that the soybean peptide QRPR activates autophagy and attenuates
the inflammatory response in the LPS-induced RAW264.7 cell model.
Obesity Therapy: How and Why?
Authors: Paccosi Sara , Cresci Barbara , Pala Laura , Rotella Carlo Maria , Parenti Astrid
Published: January 2019

Background:

Obesity represents the second preventable mortality cause worldwide, and is very often associated with type 2 Diabetes Mellitus (T2DM). The first line treatment is lifestyle modification to weight-loss, but for those who fail to achieve the goal or have difficulty in maintaining achieved results, pharmacological treatment is needed. Few drugs are available today, because of their side effects.

Objective:

We aim to review actual pharmacological management of obese patients, highlighting differences between Food and Drug Administration - and European Medicine Agency-approved molecules, and pointing out self-medications readily obtainable and widely distributed.

Methods:

Papers on obesity, weight loss, pharmacotherapy, self- medication and diet-aid products were selected using Medline. Research articles, systematic reviews, clinical trials and meta-analyses were screened.

Results:

Anti-obesity drugs with central mechanisms, such as phentermine and lorcaserin, are available in USA, but not in Europe. Phentermine/topiramate and naltrexone/bupropion combinations are now available, even though the former is still under investigation from EMA. Orlistat, with peripheral mechanisms, represents the only drug approved for weight reduction in adolescents. Liraglutide has been approved at higher dose for obesity. Anti-obesity drugs, readily obtainable from the internet, include crude-drug products and supplements for which there is often a lack of compliance to national regulatory standards.

Conclusion:

Mechanisms of weight loss drugs include the reduction of energy intake or the increase in energy expenditure and sense of satiety as well as the decrease of hunger or the reduction in calories absorption. Few drugs are approved, and differences exist between USA and Europe. Moreover, herbal medicines and supplements often sold on the internet and widely used by obese patients, present a risk of adverse effects.
Oxidative Status in Multiple Sclerosis and Off-Targets of Antioxidants: The Case of Edaravone
Authors: Agresti Cristina , Mechelli Rosella , Olla Stefania , Veroni Caterina , Eleuteri Cecilia , Ristori Giovanni , Salvetti Marco
Published: January 2019

Background:

MS is a chronic inflammatory disease of the CNS leading to demyelination and neurodegeneration, with a complex and still to be clarified aetiology. Several data, coming from patients' samples and from animal models, show that Oxidative Status (OS) plays an important role in MS pathogenesis. Overproduction of reactive oxidative species by macrophages/microglia can bring about cellular injury and ensuing cell death by oxidizing cardinal cellular components. Oxidized molecules are present in active MS lesions and are associated with neurodegeneration.

Methods:

We undertook a structured search of bibliographic databases for peer-reviewed research literature focusing on OS in MS. The contents of the selected papers were described in the context of a conceptual framework. A special emphasis was given to the results of our study in the field.

Results:

The results of our three recent studies were put in the context and discussed taking into account the literature on the topic. Oxidative damage underpinned an imbalance shared by MS and neurodegenerative diseases such as Alzheimer and Parkinson diseases. In people with clinically isolated syndrome (an early phase of MS) oxidative stress proved to contribute to disease pathophysiology and to provide biomarkers that may help predict disease evolution. A drug screening platform based on multiple assays to test the remyelinating potential of library of approved compounds showed two anti-oxidants, edaravone and 5-methyl-7- methoxyisoflavone, as active drugs. Moreover, an analysis of 'structure activity relationship' showed off-targets sites of these compounds that accounted for their remyelinating activity, irrespective of their antioxidant action.

Conclusion:

Overall, edaravone emerges as a candidate to treat complex disease such as MS, where inflammation, oxidative stress and neurodegeneration contribute to disease progression, together or individually, in different phases and disease types. Furthermore, approaches based on drug repositioning seem to maintain the promise of helping discover novel treatment for complex diseases, where molecular targets are largely unknown.
The Role of Neuropeptide Y and Peptide YY in the Development of Obesity via Gut-brain Axis
Authors: Wu Yi , He Hengxun , Cheng Zhibin , Bai Yueyu , Ma Xi
Published: January 2019

Obesity is one of the main challenges of public health in the 21st century. Obesity can induce
a series of chronic metabolic diseases, such as diabetes, dyslipidemia, hypertension and nonalcoholic
fatty liver, which seriously affect human health. Gut-brain axis, the two-direction pathway formed between
enteric nervous system and central nervous system, plays a vital role in the occurrence and development
of obesity. Gastrointestinal signals are projected through the gut-brain axis to nervous system,
and respond to various gastrointestinal stimulation. The central nervous system regulates visceral activity
through the gut-brain axis. Brain-gut peptides have important regulatory roles in the gut-brain axis.
The brain-gut peptides of the gastrointestinal system and the nervous system regulate the gastrointestinal
movement, feeling, secretion, absorption and other complex functions through endocrine, neurosecretion
and paracrine to secrete peptides. Both neuropeptide Y and peptide YY belong to the pancreatic polypeptide
family and are important brain-gut peptides. Neuropeptide Y and peptide YY have functions that
are closely related to appetite regulation and obesity formation. This review describes the role of the gutbrain
axis in regulating appetite and maintaining energy balance, and the functions of brain-gut peptides
neuropeptide Y and peptide YY in obesity. The relationship between NPY and PYY and the interaction
between the NPY-PYY signaling with the gut microbiota are also described in this review.

Parafraseamento Automático de Registo Informal em Registo Formal na Língua Portuguesa
Authors: Barreiro Anabela Marques , Rebelo-Arnold Ida , Baptista Jorge , Mota Cristina , Garcez Isabel
Published: January 2019

Este artigo apresenta o processo de automatização de parafraseamento em português e conversão de construções típicas do registo informal ou da linguagem falada em construções de registo formal usadas na linguagem escrita. Ilustraremos o processo de automatização com exemplos extraídos do corpus e-PACT, que envolvem a colocação normalizada de pronomes clíticos quando co-ocorrem com compostos verbais. A tarefa consiste em parafrasear e normalizar, entre outras, construções como vou-lhe/posso-lhe fazer uma surpresa em vou/posso fazer\-lhe uma surpresa, em que o pronome clítico lhe migra de uma posição enclítica imediatamente a seguir ao primeiro verbo do composto verbal para uma posição enclítica a seguir ao verbo principal, que é o verbo responsável pela seleção do argumento pronominal. O primeiro verbo é um verbo auxiliar ou um verbo volitivo, e.g., querer. Este é um procedimento padronizado no processo de revisão em português europeu. Casos como este representam fenómenos linguísticos em que os estudantes de língua portuguesa e falantes em geral se confundem ou onde "tropeçam". O artigo enfatiza a língua padrão em que os fenómenos observados ocorrem, descreve exemplos de interesse encontrados no corpus e apresenta uma solução automática, baseada na aplicação de gramáticas transformacionais genéricas, que facilitam a normalização de inadequações ou falhas sintáticas (registos informais) encontradas nas construções pesquisadas em construções padronizadas típicas da escrita formal ou escrita profissional.
Construções Conversas do Português do Brasil
Authors: Calcia Nathália Perussi , Araujo Vale Oto
Published: January 2019

Os estudos que descrevem as construções com os verbos-suporte (Vsup) dar, ter e fazer apontam que grande parte dos substantivos predicativos (Npred) construídos com esses verbos aceitam a transformação denominada Conversão. A conversão é uma operação formal que estabelece uma relação não-orientada de equivalência sintática e semântica (parafrástica) entre duas frases elementares, tal como dar um beijo/receber um beijo. Nessa relação o nome predicativo é mantido e a posição dos argumentos é alterada, sem alterar os papeis semânticos. Nessas construções, a sentença de orientação ativa e o Vsup ativo são considerados standard; enquanto a sentença equivalente, de orientação passiva, é considerada conversa. Este trabalho apresenta os primeiros passos de uma descrição dessas construções no português brasileiro. O estudo baseia-se na metodologia de descrição do Léxico-Gramática, a partir de matrizes binárias nas quais as colunas representam as propriedades sintático-semânticas de cada construção. Os resultados do estudo de construções com verbo-suporte podem contribuir para análise de textos, identificando as informações e a forma da estrutura, e consequentemente, enriquecendo a descrição do Português Brasileiro. Além disso, a representação dos resultados em matrizes binárias prevê uma descrição formal, que poderá ser utilizada em aplicações no Processamento de Língua Natural.
Ser docente de enfermería desde la mirada de sus participantes
Authors: Guillen Velasco Rocío Del C.
Published: January 2019

Este trabajo de corte cualitativo intenta responder a las preguntas ¿de qué hablan las maestras cuando se les pregunta sobre ser docentes en Enfermería y cómo llegaron a ella? El acopio de datos se realizó mediante el relato biográfico y el análisis del discurso fue la forma en que se intentó comprender lo dicho por las docentes Enfermeras.

Desde una forma muy general, se elaboró una narrativa de lo entendido buscando algunos anclajes teóricos que permitan entender la realidad vivida y lo que aún experimentan las informantes sobre lo que significa ser docentes y las vías por las cuales llegaron a ella y siguen en su devenir.

Lo más interesante del trabajo es que por un lado, se logró que las docentes hicieran un alto al camino para reconocer su trayectoria de vida y, por otro, se reconoció la necesidad de formarse en esta área tan compleja y rica en emociones humanas.
Enfermería transcultural, elemento vital de seguridad del paciente
Authors: Pérez Rodríguez Ma. Teresa
Published: January 2019

Podemos afirmar que el cuidado que nos identifica en la perspectiva de la enfermería transcultural es un cuidado reciproco, interactivo e integrador, en el cual las experiencias vividas y trascendentes comprenden la interacción entre personas totales con sus sentimientos, pensamientos y expresiones.

Interacción reciproca significa un encuentro de seres humanos diferentes, con sabidurías y mentalidades que cada uno ofrece en el encuentro, donde la persona del enfermo ofrece su ser total, sus conocimientos, sus observaciones y percepciones, consciente de que es un ser humane susceptible y vulnerable. EI ambiente del cuidado debe favorecer la prioridad, el pudor y la unicidad de cada ser humano, sujeto reconocido del encuentro transcultural.

Gracias a las actividades auténticas de la Enfermera (o), conocimiento, reflexión, técnicas del cuidado y momentos especiales del mismo, se da esa interacción, en la que la persona ofrece su confianza, así como su interés porque se le reestructure y reintegre como persona digna de apoyo, consideración, respeto y afecto.

Published: January 2019

Introducción: El propósito del estudio fue determinar la prevalencia de causas de hospitalización del adulto con diabetes mellitus tipo 2. Metodología: El diseño fue de tipo epidemiológico, por encuesta de prevalencia. La muestra fue a través del censo de pacientes que ingresaron a un hospital de segundo nivel. Las mediciones fueron: la cédula de identificación del paciente dividida en tres apartados: datos sociodemográficos, datos clínicos y datos de hospitalización para estimar la prevalencia. Cuestionario de Identificación de Trastornos por uso de Alcohol (AUDIT) y el cuestionario del uso de Tabaco de Fagerstrom. Resultados: Corresponden a 40 adultos hospitalizados (50% hombres y 50% mujeres). Al estimar de prevalencia por causa de hospitalización, se posicionó el pie diabético con 45% como principal, seguido de la insuficiencia renal crónica con el 40%. El consumo de alcohol y tabaco no se relacionó con la causa de hospitalización. Conclusiones: Las complicaciones que llevan a la hospitalización son importantes de valorar por el personal de enfermería, debido a la complejidad que presentan éstas, lo cual amerita intervenciones de tipo preventivo que ayuden disminuir el problema.

Colombia: Sistema financiero y pobreza
Authors: Guerrero Pino Yolanda
Published: January 2019

Entre el sistema financiero colombiano (SFC) y la línea de pobreza (LP) existen conexiones. En la perspectiva neoclásica si sistema financiero (SF) crece, la LP baja. La heterodoxa abre nuevos caminos para detectar este tipo de relaciones. Este artículo objeta las bondades del SFC sobre la LP en Colombia en el período 1994-2010. La indagación se inspiró en la literatura económica sobre inclusión, desigual, pobreza inducida y responsabilidad social del SF. Las fuentes de la refutación son un modelo autorregresivo y rezagos distribuidos, y una prueba de Granger. Los resultados indican que las variables internas del SFC: el crédito-deuda hipotecario (C-D), las daciones de bienes inmobiliarios en pago de deudas financieras (DBP) y los Tipos de Interés Activos (TIA) de la banca comercial sostienen relaciones directas, duraderas y “causales” con la LP.

Este artigo consiste em uma análise do trabalho Perigosos, subversivos, sediciosos [Cadernos do povo brasileiro] da artista plástica Leila Danziger, que integrava a exposição Hiatus: a memória da violência ditatorial na America Latina, sob a curadoria de Márcio Seligman-Silva. A exposição, montada no Memorial da Resistência de outubro de 2017 a março de 2018, foi o resultado de uma proposta a oito artistas a que trabalhassem sobre o relatório final da comissão da verdade. Este artigo pretende comparar estratégias sobre como elaborar a memória de Auschwitz, temática que ocupou os debates estéticos europeus sobretudo nos anos 1990, com a estratégia utilizada por Leila Danziger. Pretendo mostrar que a estratégia artística corresponde aos problemas concretos ligados à dificuldade do Brasil em prestar contas com seu passado ditatorial.

Samuel Beckett e o minimalismo
Authors: Gatti Luciano
Published: January 2019

O artigo propõe uma aproximação entre Samuel Beckett e um conjunto de artistas visuais, em particular escultores, associados ao Minimalismo norte-americano e à sua imediata posteridade, artistas como Donald Judd, Robert Morris, Sol LeWitt e Bruce Nauman. Essa aproximação tem por base dois elementos: 1) a utilização de procedimentos artísticos comuns a todos esses artistas, ou seja, o emprego de esquemas seriais e repetitivos na produção das obras; 2) uma análise do ensaio de Rosalind Krauss, “LeWitt in Progress”, que defende a proximidade entre tais artistas por meio de uma forma de racionalidade própria ao esquema das séries. Com base nisso, o artigo interroga se tais artistas teriam sido levados aos esquemas seriais pelo enfrentamento de problemas semelhantes em cada um de seus meios artísticos. Em outras palavras, pergunta-se qual a especificidade do recurso ao serialismo em cada meio artístico empregado por eles, da prosa às artes visuais.

No intenso agora é uma meditação sobre o suicídio baseada em uma perspectiva anti-psicológica, de fortes tintas existencialistas. O mito de Sísifo, de Camus, é a obra filosófica com a qual o filme dialoga mais diretamente. Para defender esta tese, o filme de João Moreira Salles é inserido no contexto de um debate cinematográfico sobre as relações entre o suicídio e a política que inclui uma breve análise dos seguintes filmes: Trinta anos esta noite, de Louis Malle; O inquilino, de Roman Polanski; Os amantes constantes, de Phillipe Garrel; e Morrer aos trinta anos, de Romain Goupil, filme preferido de Salles sobre o período.
Creencias y prácticas pedagógicas alrededor del clima en el aula frente al problema de las drogas
Authors: Bayas Carlota , Rodríguez Arturo , Molina Lorena , Ordóñez Esther
Published: January 2019

En el campo de la educación se aborda actualmente el problema del consumo, tenencia y micro-tráfico de drogas como uno de los mayores desafíos que enfrentan los docentes. El clima en el aula se construye a través de la interacción entre el docente y sus estudiantes y de las condiciones tanto físicas como emocionales que se presentan dentro del espacio físico donde se imparten las clases. La valoración de esta construcción conceptual denominada clima en el aula aborda un sistema de creencias complejo, comprensiones, desafíos y prácticas pedagógicas multivariadas. Objetivo: El presente estudio, realizado en dos instituciones de educación pública de Ecuador, busca conocer las creencias y prácticas pedagógicas de los docentes frente a las situaciones de riesgo y vulnerabilidad que se presentan dentro del salón de clases por la presencia de las drogas. En toda institución educativa, la expresión de las percepciones que tienen sus integrantes, la forma en que estudiantes y docentes piensan, sienten e interactúan tiene un efecto inmediato dentro del proceso de aprendizaje. Materiales y métodos: A través de un enfoque metodológico cuantitativo, los encuestados en esta investigación comparten sus creencias y prácticas pedagógicas alrededor del concepto clima en el aula.

Tratamiento informativo de la huelga magisterial en la prensa Peruana
Authors: Turpo Gebera Osbaldo
Published: January 2019

El abordaje informativo de los conflictos sociales permite estar al corriente de los acontecimientos, a través de representaciones mediáticas que modelan sistemas simbólicos de representación que destacan lo noticiable, de ese modo, reflejan imágenes que afectan o implican su comprensión. En ese sentido, la huelga magisterial del 2017, constituyó un hito informativo que demanda ser analizado. Objetivo. Determinar el tratamiento informativo de los principales medios a la huelga de docentes, su representación noticiosa y los aspectos hegemonizados. Materiales y métodos. A partir de una revisión de las noticias publicadas sobre la huelga docente y siguiendo una metodología inductiva, se categorizó la información publicada, a fin de reconocer el aporte informativo, el tipo de información y los mensajes implícitos publicados. Resultados. En el tratamiento informativo se privilegió la narrativa de los hechos, lo coyuntural más que la profundización. Las representaciones noticiosas resaltaron lo escandaloso, desnaturalizando así, la esencia del conflicto, optando por el sensacionalismo, al vincularlos al violentismo, la anarquía y el caos urbano. Conclusión. La prensa al informar adoleció de dificultades para la representación noticiosa, soslayando una mejor comprensión.

The forgotten Atanasije Vuckovic
Authors: Tartalja Ivo
Published: January 2019

The paper discusses the publicist Atanasije Vuckovic as a predecessor of
Svetozar Markovic. Both were educated almost simultaneously in Belgrade,
Russia and Switzerland, and they probably met and acquainted in Z?rich in
their polytechnical studies, where Vuckovic graduated from chemistry. His
articles treated the injustices of growing capitalism, workers' rights,
advanced schooling, women?s rights and a democratic form of government. He
expressed well-developed ideas for the progress of education, freedom of
speech and the press, industry, agriculture, roads, regulation of rivers and
their use for transportation. He particularly championed better living
conditions in the cities and villages. As a representative from Morava County
in Serbian Parliament, he suggested a number of useful innovations for the
improvement of people's life and the state's progress.
The forgotten dream of the emperor Nebuchadnezzar
Authors: Milovanovic Ksenija
Published: January 2019

This paper is dedicated to the Old Paper Apocrypha, which speaks about
emperor Nebuchadnezzar. The starting point of the Apocrypha is the second
chapter of the Book of the prophet Danilo with considerable deviations. The
basis is the interpretation of the Nebuchadnezzar's forgotten dream, whose
explication is made by the prophet Samoil. The apocryphal and biblical texts
are comparatively analyzed. It was pointed out to the anticipation and
symbolic function of the dream in other Old Testament stories. The work
examines paleographical and orthographical characteristics of the text. The
supplement features the adapted text of The story of prophet Samoil, from
XIV century.
Effect of the degree of plastic deformation on the thermal electromotive force of cu-x5crni1810 steel thermocouple
Authors: Milicevic Ivan , Spasojevic Milica , Slavkovic Radomir , Spasojevic Miroslav , Maricic Aleksa
Published: January 2019

The thermal electromotive force (TEMF) and the thermal electromotive force
coefficient (TEMFC) of the thermocouple consisting of a copper wire and an
(X5CrNi1810) steel wire plastically deformed under tension or bending
conditions were found to increase with increasing degree of plastic
deformation. The increase in the degree of deformation disturbs the
microstructure of steel due to increases in the density of chaotically
distributed dislocations and internal microstress, resulting in a decrease
in the electron density of states near the Fermi level. Through the effect
of thermal energy, annealing at elevated temperatures up to 300?C leads to
microstructural ordering along with simultaneous increases in the free
electron density of states, TEMF and TEMFC. Based on the temporal change of
the TEMF, the kinetics of microstructural ordering was determined. During
the initial time interval, the process is a kinetically controlled
first-order reaction. In the second time interval, the process is controlled
by the diffusion of reactant species.

Published: January 2019

Lanthanum silicate oxyapatite (LSO) is a promising ion conductive ceramic
material, which has higher oxygen ion conductivity at intermediate
temperatures (600-800?C) compared to yttria-stabilized zirconia. Its
mechanical properties, though important for any of its applications, have
been scarcely reported. In this study, we compare apparent densification,
open porosity and Vickers hardness of samples conformed by uniaxial pressing
and slip casting and fired up to 1600?C. Colloidal processing was optimized
for slip casting in order to get high green densities. At sintering
temperatures higher than 1400?C, both processing routes yielded comparable
densities, although uniaxially pressed samples show slightly better
mechanical properties, evidencing that slip cast ones already underwent a
grain growth process.
