Authors: Nascimento Vagner Ferreira do , Hattori Thalise Yuri , Terças-Trettel Ana Cláudia Pereira
Published: December 2019

Resumo A formação do enfermeiro no Brasil, ainda se apresenta como um desafio para as universidades, face as diversidades étnicas e as particularidades regionais existentes. Assim, o objetivo do estudo foi identificar os desafios no processo de formação de enfermeiros indígenas em Mato Grosso, Brasil. Trata-se de estudo exploratório e qualitativo, junto a 11 enfermeiros indígenas. A análise dos dados, baseou-se na interculturalidade de Paulo Freire. Verificou-se que todos participantes, buscam a integração dos saberes tradicionais indígenas com os conhecimentos técnico científicos, durante suas práticas, o que facilita a interação satisfatória com a comunidade. Durante a graduação de Enfermagem tiveram pouco ou nenhum contato com conteúdos relacionados à saúde indígena e ao término da formação vislumbravam despreparo para atender as variadas demandas em saúde. Historicamente, apresentam-se subalternizados em relação aos não indígenas, o que reflete em desvantagens no processo de ensino-aprendizagem, tanto relacionados aos aspectos técnicos/tecnológicos como sociais.
O intangível na produção do cuidado: o exercício da inteligência prática em uma enfermaria oncológica
Authors: Fonseca Maria Liana Gesteira , Sá Marilene de Castilho
Published: December 2019

Resumo Este artigo resulta de uma pesquisa cujo objeto é o saber-fazer dos trabalhadores de enfermagem. O objetivo principal foi investigar os usos da inteligência prática, em uma equipe de enfermagem de uma enfermaria oncológica no Rio de Janeiro. Partimos do pressuposto de que, a despeito do sofrimento inerente ao trabalho em saúde, este pode conter uma dimensão criativa e potente no exercício do cuidar, mesmo diante dos desafios colocados pelas precárias condições de trabalho, pela demanda crescente de pacientes e pelas exigências de produtividade. Foram realizadas observação participante, entrevistas em profundidade e entrevistas em grupo com trabalhadores da enfermaria selecionada. Observamos duas principais formas de manifestação da inteligência prática. A primeira, como exercício da palavra e da escuta. A segunda, como exercício da produção de conforto. Tais formas de inteligência prática se interpenetram e não são passíveis de captura por números, indicadores e métodos de avaliação do desempenho. São invisíveis para instrumentos que não passem pela palavra dos trabalhadores. Conclui-se pela necessidade de criação de espaços coletivos em que gestores e trabalhadores possam expressar e validar socialmente o saber-fazer e as experiências dos trabalhadores.
Trabalhadores da enfermagem: conquista da formalização, “dureza” do trabalho e dilemas da ação coletiva

Published: December 2019

Resumo A singularidade das categorias de enfermagem na participação sociopolítica, especificamente sua ação coletiva, é a temática analisada. O artigo associa as condicionantes: origem social e aspectos do mercado de trabalho à ação política dos profissionais. A partir da associação analítica do estudo de caso ampliado, articulamos a interpretação da base de dados da Pesquisa Perfil da Enfermagem no Brasil, especificamente, sob os eixos: identificação socioeconômica, mercado de trabalho e condições de trabalho, com estudo etnográfico e entrevistas semiestruturadas em três unidades hospitalares. A revisão bibliográfica demonstra a inserção desses indivíduos sem secundarizar sua particularidade: o processo histórico de proletarização na formação social brasileira, a inserção feminina no mercado de trabalho e a relação com sindicatos. O histórico dos trabalhadores pautados pela inexperiência em ações de resistência ou representação sindical, associado à valorização do emprego como ascensão social resultam na configuração de regimes de trabalho assimétricos, elemento dificultador de ações organizadas, aspecto fundamental para a melhora das condições de trabalho.

Published: December 2019

ABSTRACT The objective of this study was to determine the dual crop coefficient of an early-cycle soybean cultivar for the city of Tangará da Serra, MT, Brazil, using high-precision lysimeters. The method used was the dual crop coefficient (dual Kc) of FAO Bulletin 56, constitued by soil evaporation coefficient (Ke), determined by microlysimeters, and by basal crop coefficient (Kcb), determined by weighing lysimeters. Reference evapotranspiration (ETo) was calculated using the Penman-Monteith equation. Soybean sowing and harvesting were performed in the 2015/16 season with spacing of 0.45 m between rows. The reference evapotranspiration (ETo) estimated for the cultivation period was 267.06 mm; the crop evapotranspiration was 323.61 mm throughout its cycle. The Kcb values determined by lysimeters for soybean cultivation were 0.47, 1.15 and 0.89 for the initial, intermediate and final stages, respectively; Ke values at the initial, intermediate and final stages were 0.94, 0.14 and 0.44, respectively.

Authors: Santana Júnior Edvaldo B. , Coelho Eugênio F. , Gonçalves Karoline S. , Cruz Jailson L.
Published: December 2019

ABSTRACT The purpose of the study was to evaluate the effect of salinity levels of irrigation water on physiology and growth of banana cultivars during the vegetative stage. The experiment was carried out following a completely randomized design in split plots, with four levels of salinity in irrigation water (0.5, 2.0, 3.0 and 4.0 dS m-1) and four banana cultivars (Pacovan, Prata Anã, BRS Platina and Princesa) with three repetitions. Stomatal conductance, transpiration, relative water content, leaf water potential and proline concentration were evaluated at 150 days after transplanting (DAT), besides plant height, stem diameter and leaf area. All variables showed sensitivity to the increase of salinity level of irrigation water. The results of soil water extraction, relative water content in leaf (RWC), leaf water potential and proline content differed (p ≤ 0.05) among the cultivars. Prata Anã and BRS Platina cultivars were the ones with lowest sensitivity, while Pacovan and BRS Princesa cultivars showed larger variation of soil water extraction and RWC with the increase in irrigation water salinity (electrical conductivity), being considered the ones of highest sensitivity to salinity in this study. Banana crop growth as a consequence of physiological effects was inhibited by the increase in water salinity, mainly in “BRS Princesa” cultivar.

RESUMO Este estudo busca descrever e analisar o fenômeno da síncope da vogal postônica não final no falar paranaense interiorano, com base em dados coletados em entrevistas realizadas pelo Projeto Atlas Linguístico do Brasil (ALiB), em dezesseis pontos de inquérito situados no interior do Paraná, totalizando 64 informantes. Desse modo, foram avaliadas a frequência e possíveis fatores linguísticos e extralinguísticos que podem condicionar a síncope/manutenção da vogal postônica não final das proparoxítonas em onze itens lexicais: lâmpada, elétrico, fósforo, pólvora, abóbora, árvore, sábado, número, fígado, vômito, hóspede , que constam do Questionário Fonético-Fonológico (QFF) do Questionário do ALiB (COMITÊ NACIONAL DO PROJETO ALiB, 2001). A investigação fundamenta-se na perspectiva da Dialetologia Pluridimensional (THUN, 1998) e à luz do modelo fonológico autossegmental para a sílaba, em análise do padrão silábico do português brasileiro (COLLISCHONN, 1996; BISOL, 1999). Constatamos que o contexto fonológico das vogais postônicas e segmentos adjacentes podem interferir no condicionamento da síncope, enquanto as variáveis extralinguísticas não se mostraram producentes para esse processo em nosso corpus .

Authors: MORA-BUSTOS Armando
Published: December 2019

RESUMEN El objetivo de este trabajo es describir la estructura de las construcciones escindidas en la lengua mazahua de San Pedro Potla (Temascalcingo, Estado de México). Este estudio se ha realizado bajo el planteamiento de Lambrecht (2001), quien considera que la construcción escindida es una estructura oracional compleja que está formada por una cláusula matriz y una cláusula relativa; esta cláusula binaria expresa una sola proposición semántica. Teniendo en cuenta esta consideración, se ha identificado una serie extensa de construcciones escindidas, éstas están formadas por la marca ŋɡè, la frase focalizada y la cláusula relativa. Para dar cuenta del objetivo ha sido necesario atender ciertos aspectos de la gramática de la lengua como orden de constituyentes, tipos de cláusulas de relativo, subordinantes y funciones gramaticales de ŋɡè. A través de las clases de construcciones escindidas se puede mostrar que, en ciertos contextos, igualmente, aparece escindida la información topicalizada. Los datos corresponden a historias de vida, narraciones y relatos.

Published: December 2019

Resumen Este artículo se propone estudiar el empleo de los tiempos verbales en narraciones escritas, producidas por niños hablantes de español como lengua de herencia (ELH), que crecen en un contexto plurilingüe. En esta contribución, analizamos la distribución y el nivel de adecuación de los tiempos verbales, con un foco particular en dos aspectos problemáticos para los hablantes de lengua de origen: el contraste perfectivo/ imperfectivo y el uso del subjuntivo. Asimismo, comparamos los textos de hablantes de lengua de herencia (LH) con narrativas producidas por niños que crecen en un contexto monolingüe español. Los participantes fueron 165 niños (edades 8.6 -13.7): 118 niños ELH y 47 niños que crecían en un contexto en el que el español es la lengua mayoritaria. Los resultados mostraron un nivel de adecuación en el empleo de los verbos y una distribución similar de los tiempos utilizados en ambos grupos. Sin embargo, los niños del grupo ELH utilizaron formas particulares de los tiempos del pasado y eran menos precisos en la oposición del aspecto y en el uso del modo subjuntivo.

Breakthrough Cancer Pain in Patients Receiving Low Doses of Opioids for Background Pain
Authors: Mercadante Sebastiano , Caraceni Augusto , Masedu Francesco , Scipioni Teresa , Aielli Federica
Published: December 2019

Background

This study aimed to assess the characteristics of breakthrough cancer pain (BTcP) in patients receiving low doses of opioids for background pain in comparison with patients receiving at least 60 mg of oral morphine equivalents (OME).

Materials and Methods

Patients with advanced cancer receiving less than 60 mg/day of OME with episodes of BTcP were included in the analysis (group L). Data were compared with patients receiving doses of opioids ≥60 mg of OME (group H). Pain intensity, current analgesic therapy, number of BTcP episodes, intensity of BTcP, its predictability and triggers, onset duration, interference with daily activities, BTcP medications, and time to meaningful pain relief were collected. Adverse effects imputable to a BTcP medication were recorded.

Results

A total of 1,418 and 2,474 patients were included in groups L and H, respectively. A lower number of BTcP episodes (p = .005), a lower BTcP intensity (p = .0001), a faster BTcP onset (p = .024), and a longer time to meaningful pain relief after taking a BTcP medication (p = .009) were found in group L as compared with group H. In group L, BTcP interference on daily activity was less than in group H (p = .009). Patients in group L were less likely to be prescribed an opioid as BTcP medication in comparison with patients in group H (p = .0001). Opioid doses used for BTcP were significantly higher in group H. Patients in group L were more likely to be less satisfied (p = .003) than patients in group H. No adverse effects of severe intensity were reported in both groups.

Conclusion

Patients receiving lower doses of opioids exhibit some differences in BTcP presentation: fewer episodes with lower intensity and a faster onset, a longer time to meaningful pain relief, and less satisfaction with BTcP medication. A relevant percentage of patients was receiving fentanyl preparations normally reserved for patients receiving higher doses of opioids.
Acoustic emission generated by granular soil−steel structure interaction
Authors: Smith A. , Heather-Smith H. J. , Dixon N. , Flint J. A. , Pennie D.
Published: December 2019

This study has established quantitative interpretation of acoustic emission (AE) generated by granular soil−steel structure interaction. This new knowledge will enable the evolution of soil−structure interaction behaviour to be interpreted from AE measurements. AE monitoring could now provide early warning of soil−structure system (e.g. buried pipelines, pile foundations and retaining structures) limit-state failures in the field and enhance insights into element and physical model tests in the laboratory. The results from a programme of large direct-shear tests performed on granular soil−steel interfaces show that AE generation is influenced by the normal effective stress, mobilised shearing resistance and shearing velocity. Compression-induced AE activity in granular soil−steel systems is negligible until the current stress conditions exceed the maximum that has been experienced in the past. Relationships have been quantified between AE and normal effective stress, mobilised shearing resistance and shearing velocity, enabling quantitative interpretation of cyclic and accelerating soil−structure interaction behaviour from AE measurements.
Multi-Ricker Spectral Modeling in the S-transform Domain for Enhancing Vertical Resolution of Seismic Reflection Data
Authors: Winardhi Sonny , Pranowo Waskito
Published: December 2019

DOI: 10.17014/ijog.6.3.223-233We present a relatively straightforward methodology for extending seismic bandwidth and hence enhancing the seismic resolution by performing time-variant deconvolution. We use the generalized S-transform (GST) approach in order to properly compute the time-frequency components of the seismic reflection trace. In estimating the time-variant wavelet, we propose a spectral modeling method named multi-Ricker spectral approximation (MRA). After obtaining the estimated wavelet spectrum at each time sample, a deconvolution filter can then be built and applied in the S-transform domain. This proposed time-variant seismic enhancement method needs neither information on subsurface attenuation model nor assumption that the subsurface reflectivity is random. It is a data-driven methodology which is based on the seismic data only. We validate this proposed method on a synthetic and apply to a field data. Results show that, after enhancement, overall seismic bandwidth can be extended resulting in higher vertical resolution. Correlation with VSP corridor stack at well location ensures that the generated reflection details after enhancement is geologically plausible.
Tephra-stratigraphy and Ash Componentry Studies of Proximal Volcanic Products at Mount Tangkuban Parahu, Indonesia: An Insight to Holocene Volcanic Activity

Published: December 2019

DOI: 10.17014/ijog.6.3.235-253Tangkuban Parahu Volcano is one of the most active volcanoes in West Java, Indonesia, although most of the recent eruptions were relatively mild (e.g. 2013 eruption). However, there is still little information from the volcanic products in the proximal area. Here, a new documentation from the proximal volcanic succession is provided, including tephra-stratigraphy, componentry analysis, and petrography of volcanic products. Detailed mapping of the proximal area shows that the volcanic products are predominantly composed of alternating fine-clay and coarse ash, lapilli tuff, and pyroclastic breccia within ten tephra units. Componentry of ash particles revealed the presence of five components, associated with hydrothermally altered lithics, oxidized lithics, coherent crystalline lithics, magmatic juvenile, and free crystal in entire eruptive products. These indicate that the subvolcanic hydrothermal system has been developed since the Holocene and associated with a continual introduction of magmatic intrusion. Petrographic observation shows the presence of hydrothermal minerals of quartz or silica accompanied by alunite and kaolinite, representing acidic alteration within the crater-conduit. The existence of a silicified zone indicates that the subvolcanic hydrothermal system played an essential role as a cap-rock of pressurized gas and steam at depth (200-500 m), whereas magmatic injection caused the vapour plume expansion. The observation concluded that the proximal volcanic succession captured the evidence of coupled phreatic and phreatomagmatic activities during the latest development of Mount Tangkuban Parahu.

Participação num ambiente datificado: questões sobre literacia de dados
Authors: Gutiérrez Miren
Published: December 2019

No contexto político, entende-se por participação o envolvimento dos cidadãos na tomada de decisões, incluindo mecanismos para que as pessoas intervenham nas escolhas políticas e sociais, entre outras áreas de ação. Esses mecanismos são cruciais, pois a democracia depende da participação cívica na vida política. No entanto, na era do big data, a participação não é possível sem o acesso e controle de dados por parte das pessoas; isto é, os direitos civis tornam-se direitos digitais. Este artigo trata da literacia de dados como um filtro para a participação e do papel das pessoas comuns no ambiente e nos processos de datificação.Como a participação num mundo datificado depende da capacidade das pessoas de entrar na contenda, questões sobre onde se estabelecem as linhas de separação entre especialistas e não especialistas (ou seja, cidadãos comuns) e se a intervenção na infraestrutura de dados requer um grau de literacia de dados para participação efetiva constituem uma discussão relevante para a prática e teoria do ativismo como uma forma de envolvimento político ou cívico. O envolvimento político é entendido aqui como uma ação coordenada voltada para a resolução de problemas, campanhas e assistência aos cidadãos. Ou seja, para resgatar a participação política num domínio de dados, é necessário um certo grau de capacitação. Partindo de uma taxonomia do envolvimento em data mining (Kennedy, 2016) e casos empíricos de mapeamento de crises (Gutierrez, 2018a, 2018b), este artigo teórico propõe conceptualizações para pensar sobre as implicações da participação na contemporaneidade.

Published: December 2019

Исследована адсорбция ионов Zn2+ нативными и модифицированными в слабоконцентрированных (1-3 %) растворах H2SO4 опилками акации ушковидной (Acacia auriculiformis). Изотерма адсорбции ионов цинка нативными опилками акации относятся к изотермам I типа, согласно классификации ИЮПАК и L типу, согласно классификации Гильса. Максимальная сорбционная емкость опилок акации по ионам цинка составляет 7.5 мг/г. С целью увеличения сорбционных показателей, исследуемые опилки обрабатывались слабоконцентрированными растворами серной кислоты при 20оС в течение 5 ч. С увеличением концентрации раствора серной кислоты сорбционная емкость опилок поионам цинка увеличивается. Обработка опилок 3%-ным раствором H2SO4 способствует увеличению максимальной сорбционной емкости по ионам Zn2+ c 7.5 до 36.5 мг/г. Полученные изотермы адсорбции обрабатывалась с помощью моделей Ленгмюра, Фрейндлиха, Дубинина-Радушкевича и Темкина. Определены уравнения регрессии и коэффициенты аппроксимации, а также термодинамические параметры процессов (энергия сорбции и энергия Гиббса). Изотерма адсорбции нативными опилками наиболее адекватно описывается моделью Темкина, модифицированными – моделью Фрейндлиха. Значения энергии адсорбции менее 8 кДж/моль и энергии Гиббса в пределах от -4 до 0 кДж/моль сви-детельствуют о протекании самопроизвольной физической адсорбции. Получены кинетические зависимости процессов адсорбции ионов цинка нативными и модифицированными опилками акации. Обработкой кинетических зависимостей в рамках диффузионной модели Бойда рассчитаны коэффициенты Био для исследуемых процессов, значения которых соответствуют протеканию процессов смешанной диффузии, то есть лимитирующими стадиями процессов адсорбции являются, как внешняя, так и внутренняя диффузия.
Сорбция ферментов на клеточной мембране и субклеточных структурах: механизмы, биологическая роль (обзор)
Authors: Basharina Olga V. , Artyukhov Valerij G.
Published: December 2019

Многие клеточные ферменты обратимо связываются с клеточной мембраной и компонентами цитоскелета, сорбция/десорбция является важным механизмом регуляции активности таких ферментов и ферментных систем, а также одним из способов передачи сигнала в клетке. Изучение механизмов адсорбции ферментов позволяет не только регулировать уровень их активности, но и дает возможность управлять внутриклеточной сигнализацией. В качестве примеров рассматриваются некоторые ферменты гликолиза, антиоксидантной системы; как пример ферментов, участвующих в передаче сигнала – NO-синтаза, ряд протеинкиназ.Изменение локализации ферментов в клетке происходит как из-за изменения параметров внутриклеточной среды, так и в результате ковалентной модификации белка (фосфорилирование, ацилирование и др.). В ряде случаев сорбция на мембране обусловливает повышение локальной концентрации субстрата, что приводит к повышению активности фермента; по-видимому, с этим может быть связана локализация на мембране таких ферментов-антиоксидантов, как СОД и каталаза.Механизм изменения активности ферментов при их сорбции на мембране может быть обусловлен модификацией микроокружения, конформационной подвижности белка, экранированием активного центра; может изменяться аллостерический механизм регуляции активности фермента.Поскольку все указанные процессы должны быть обратимы, то и сорбция ферментов в этих случаяхосуществляется за счет слабых сил – водородных связей, электростатических или гидрофобных взаимодействий.Многие цитозольные белки выполняют свои функции, находясь в ассоциированном с мембраной состоянии. Их ассоциация с поверхностью мембраны происходит с помощью структурных белковых модулей (доменов), имеющих специфичность к тем или иным липидам. Цитозольные белки-эффекторы обладают структурными доменами, способными связываться с фосфоинозитидами мембранной поверхности. В связанном с мембранами состоянии белки-эффекторы находятся, в основном, в комплексе с фосфоинозитид-специфичными киназами и фосфатазами, а также с малыми GTP-азами, что необходимо для адресной ассоциации белков-эффекторов с мембранами органелл.
Gradient boosting for the prediction of gas chromatographic retention indices
Authors: Matyushin Dmitriy D. , Sholokhova Anastasia Yu. , Buryak Aleksey K.
Published: December 2019

The estimation of gas chromatographic retention indices based on compounds structures is an importantproblem. Predicted retention indices can be used in a mass spectral library search for the identificationof unknowns. Various machine learning methods are used for this task, but methods based on decisiontrees, in particular gradient boosting, are not used widely. The aim of this work is to examine the usability ofthis method for the retention index prediction. 177 molecular descriptors computed with Chemistry Development Kit are used as the input representation of a molecule. Random subsets of the whole NIST 17 database are used as training, test and validation sets. 8000 trees with 6 leaves each are used. A neural network with one hidden layer (90 hidden nodes) is used for the comparison. The same data sets and the set of descriptors are used for the neural network and gradient boosting. The model based on gradient boosting outperforms the neural network with one hidden layer for subsets of NIST 17 and for the set of essential oils.The performance of this model is comparable or better than performance of other modern retention prediction models. The average relative deviation is ~3.0%, the median relative deviation is ~1.7% for subsets of NIST 17. The median absolute deviation is ~34 retention index units. Only non-polar liquid stationary phases (such as polydimethylsiloxane, 5% phenyl 95% polydimethylsiloxane, squalane) are considered. Errors obtained with different machine learning algorithms and with the same representation of the molecule strongly correlate with each other.
Масс-спектрометрическая визуализация для исследования поверхности стали
Authors: Kuznetsova Elena S. , Pytskii Ivan S. , Buryak Alexey K.
Published: December 2019

Визуализация масс-спектрометрическими методами исследования поверхности широко используется для построения карт распределения различных соединений. В настоящей работе данныйинструмент впервые применён для исследования морфологии и состояния различных промышленных сталей. Ранее метод применялся только для визуализации с тонких поверхностей. Авторами показана принципиальная возможность оценки состояния поверхности стали и скорости протекания на ней коррозионных процессов. Показано, что при образовании продуктов коррозии последние легко и на низком уровне обнаруживаются в виде кластерных ионов, что позволяет легко определять начинающуюся коррозию. Визуализация наглядно показывает степень локализации и распространения коррозии, которая на сталях проходит сразу почти по всей поверхности. Также на поверхности стали обнаружены следы адсорбции хлора, который является потенциальным активатором коррозии и показана его локализация. Также возможно обнаружить продукты коррозии и адсорбированные на поверхности соединения, построить диаграмму распределения по широкой области поверхности любого обнаруженного соединения, провести локализацию исследуемой области для изучения её в сочетании с классическими методами исследования поверхности, проводить общий контроль состояния поверхности сплава во времени при его эксплуатации. Метод является уникальным, не имеет аналогов в мире и может быть распространён на любые другие поверхности и материалы

В работе рассматривается метод сбора конденсата выдыхаемого воздуха (КВВ) из выдыхаемой воздушной смеси с учетом сорбционного взаимодействия с пластиком пробирок типа Фалькон.Показано, что ключевым фактором, повышающим эффективность сбора перекиси водорода, являетсяохлаждение пробирки для сбора образцов. По-видимому, это способствовало снижению сорбционного воздействия H2O2 с полипропиленовой поверхностью пластика и соответственно приводило к снижению скорости его распада до воды. В результате работы нами был модифицирован метод измерения концентрации H2O2 в КВВ с использованием реагента Amplex® Ultra Red. Применяя данный метод, установлено, что у пациентов с раком легкого уровень H2O2 в КВВ 9 раз выше, чем у здоровых людей. Полученные данные свидетельствуют о том, что концентрация H2O2 в КВВ может являться потенциальным маркером для ранней диагностики рака легкого
Comparison of Some Physical and Mechanical Properties of Waterborne Acrylic Coating Systems Containing Commercial UV Absorbers and Tree Bark Extracts
Authors: ÖZGENÇ Özlem , KUŞTAŞ Süleyman , DURMAZ Sefa
Published: December 2019

Aim of study: The aim of this study was to compare solid content, dry film thickness, and adhesion strength of different tree bark extract based and a commercial UV absorber.

Materials and methods: Waterborne acrylic-based coating systems containing 5 different tree bark extracts (maritime pine, Calabrian pine, black pine, alder, fir) and a commercial UV absorber (Tinuvin 400 DW) were applied to 2 different wood species; Scots pine (Pinus sylvestris L.) and beech (Fagus orientalis L.). The dry-film thicknesses of the coatings were measured with light microscopy. The adhesion strength of the coatings was determined to investigate the bonding ability of the coatings with wood surfaces. The solid contents of the coatings were also determined.

Main results: Permeability is an important parameter for dry-film thickness and adhesion strength. Wood species also influenced the dry-film thickness as well as adhesion strength. The dry-film thicknesses of the coatings containing bark extracts were higher than those with commercial UV absorbers. Similarly, the solid content of the coating containing maritime pine bark extract was found to be the highest.

Highlights: The dry-film thickness and adhesion strength of waterborne acrylic coatings on wood substrate seem to be affected by addition of tree bark extracts.

Developing PowerPoint Standards for Teaching Chinese as a Foreign Language
Authors: Gao Siyi
Published: December 2019

As we live in a time when standards, frameworks, and benchmarks are becoming increasingly prominent, it makes sense that some sort of teacher technology standards would be desirable. Standards on the state or national levels call for the integrating of multimedia into teaching, but there are not clear guidelines illustrating how integrating a technology into the classroom should be accomplished. Nor is there an evaluation system in place to ensure that teachers possess the multimedia skills and knowledge required in teaching. It is thus important to devise a set of teacher technology standards as a resource for teachers as they attempt to integrate multimedia into their curricula. Therefore, this study provided a set of guidelines and standards for evaluating PowerPoint presentations for use in language teaching to provide more support to language teachers at the institutional level. In this article, four case studies of PowerPoint presentation in Chinese language teaching sample slides are explored to show how the devised standard guidelines and a score assessment system can be used to evaluate the effectiveness of a presentation and thus to help language instructors to develop their skills in making PowerPoint Presentations and improving teaching effectiveness. A proposed teacher PowerPoint standards were developed based on the author’s personal experience teaching Chinese using multimedia in classrooms in China, Europe and America will also be shared in this case study.

Published: December 2019

In 2013, the English curriculum of the Israeli educational system underwent a significant reform, aimed to improve students' achievements in English and close the gaps between students’ achievements in Israel, and students’ achievements in other OCED countries in the subject matter. However, all indicators show that after the implementation of the new program, achievements of most Israeli students' in English, especially those of Israeli Arab students, do not meet expectations. Therefore, we interviewed 10 English teachers working in the Israeli Arabic school system, with at least 13 years seniority, in hope to find out why the new curriculum does not accomplish its goals. The findings of this study reveal that teaching English according to the new curriculum is challenged in several ways, some of which are curriculum related, others relate to the training of the teachers, and other challenges relating to the school, and the students population.
A Study on the Anti-preemptive Usages of Person Deixis—Taking Instances from Cyber Language
Authors: Fan Hongya , Song Rui
Published: December 2019

Although numerous researches have been conducted to probe into the anti-preemptive usages of person deixis, few researches have been carried out on that of cyber languages. Therefore, this paper mainly investigates the anti-preemptive usages of person deixis in cyber language, collects the linguistic data of buyers and sellers on Taobao and the discursive practices posted on Weibo, and analyses the pragmatic functions of the anti-preemptive usages of person deixis with relevant pragmatic theories. The study applies the egocentricity of deixis as theoretical framework and makes a comprehensive analysis of the data, aiming to provide a new perspective for the study of deixis. The study yields four influencing factors of anti-preemptive usages of person deixis: lack of deictic context, pragmatic intention of the speaker, social factors and register factors. This paper bears both theoretical and practical values. Theoretically, it is an empirical attempt to the study on anti-preemptive usages of person deixis in the field of computer-mediated communication. From a practical point of view, the findings of the study are conductive to provide interlocutors with guidance on the use of person deixis whether in virtual context or real life communication.
The evaluation of corrosion rate of steel during chemical cleaning of steam boilers
Authors: Fedorova А.Yu. , Bushuev Е.N.
Published: December 2019

Traditional and new washing acid reagents are used for chemical cleaning of internal surfaces of steam-water pipes of boilers. In previous studies, the rate of removal of lumpy and uniform deposits in the evaporative pipes of high-pressure steam boilers depending on the type of cleaning solution and the duration of cleaning was obtained. However, during chemical cleaning, removing deposits is accompanied by corrosion processes of the metal pipes, which leads to their loss. In the scientific and technical literature there are practically no data characterizing this process when using new detergent reagents. The aim of the study is to obtain experimental data on the corrosion rate of steels during the acid stage of chemical cleaning with the use of new cleaning reagents such as Antirzhavin, Deskam and Auge Pro AC 60. The gravimetric method of determination of metal corrosion rate of evaporative pipes is used. The samples of corrosion in cold and heated washing solutions during chemical cleaning from deposits by etching are employed. The laboratory testing has revealed the dependences of corrosion rate of carbon steel of boiler evaporative pipes and corrosion indicating plates in heated and not heated washing solutions of the inhibited hydrochloric acid and acid reagents on cleaning duration. It has been found that the corrosion rates of carbon steel are reduced during the cleaning process and at the end of the acid stage in solutions of inhibited hydrochloric acid and reagent solutions have values exceeding the maximum permissible corrosion rate in a cold inhibited technical solution of hydrochloric acid. However, they are less than those for pure metal and metal with scale. The experimental data obtained can be used in the selection of a chemical reagent for acid cleaning and its optimal duration, as well as in the selection of the method of steel corrosion control during cleaning.

Apparatuses with fluidized bed are widely used in the solid fuel energetic, chemical and other industries. In particular, fluidized bed furnaces play the increasing role for thermo-chemical treatment and burning the solid fuels including bio-fuels. The use of pulsating gas flows is one of the possible ways to intensify the process of gas-particle interaction. However, the efficiency of the way is not always obvious, and new approaches are needed for preliminary estimation of its advantages. The method of mathematical modeling is used to solve the above problem. The model is based on the set of differential equations of a single particle motion in the upstream gas flow with variable with time velocity, and with variable with time particle properties due to this or that thermo-physical or chemical process of gas-particle interaction. The study of influence of the process parameters on its efficiency is done by numerical methods. The model of the effect of oscillations in the gas flow on the efficiency of particle processing in a circulating fluidized bed has been developed. The necessary time for enough particle treatment is compared for different amplitude and frequency of gas flow oscillation. The most considerable gain in time is being reached for the strong dependence of the reaction rate constant on the velocity of flow around the particle. In this case the optimum frequency of oscillations exists that give the maximum gain in time. The growth of the amplitude leads to the monotonic increase of the gain in time, or gives the optimum amplitude. Transition to the pulsating gas flow in a circulating fluidized bed reactor leads to considerable gain in time of particle treatment only in the case of strong dependence of the reaction rate constant on the velocity of flow around the particle. In this case the optimum frequency and amplitude of oscillation exist that gives the maximum gain in time.
Analytical solution to the problem of heat transfer using boundary conditions of the third kind
Authors: Eremin A.V. , Gubareva K.V.
Published: December 2019

Non-stationary heat transmission within solid bodies is described using parabolic and hyperbolic equations. Currently, numerical methods for studying the processes of heat and mass transfer in the flows of liquids and gases have disseminated. Modern programs allow the automatic construction of computational grids, solutions to the systems of equations and offer a wide range of tools for analysis. Approximate analytical solutions have significant advantages compared to numerical ones. In particular, the solutions obtained in an analytical form allow performing parametric analysis of the system under study, configuration and programming of measurement devices, etc. Based on the joint use of additional desired function and additional boundary conditions in the integral method of heat balance, a method of mathematical modeling for the heat transfer process in a plate under symmetric boundary conditions of the third kind has been developed. Using the heat flux density as a new desired function, the method for solving heat conduction problems with boundary conditions of the third kind has been proposed. Finding a solution to the partial differential equation with respect to the temperature function presents integrating an ordinary differential equation with respect to the heat flux density on the surface of the studied zone. It has been shown that isotherms appear on the surface of the plate with a certain initial velocity which depends on the heat transfer intensity. The calculation results have been compared to the exact solution. The presented method can be used in determining the heat flux density of buildings and heating devices, finding heat losses during convective heat transfer and designing heat transfer equipment. The results can be applied to increase the validity and reliability of the calculation of actual losses and balance of thermal energy. The method reliability, validity and a high degree of approximation with about 3% inaccuracy have been demonstrated. The accuracy of the solution depends on the number of approximations performed and is determined by the degree of the approximating polynomial.
Russian painting of the 19th century in the context of the projective aesthetics of N.F. Fyodorov
Authors: Titarenko E.M.
Published: December 2019

The article is dedicated to the insufficiently studied problem of N.F. Fyodorov’s projective aesthetics research connected to his interpretation of Russian painting of the 19th century. The objects of the analysis are such works of the philosopher as “The Question of Restoration of Kinship among Mankind. The Means for the Restoration of Kinship (Sobor)” (1880s), “About the Kremlin Walls Paintings” (1893), “Kremlin Walls” (1893), “The brilliant robber. (About Ge’s Painting “The Crucifixion”)” (1894), “Moscow Rumyantsev’s Museum by the Kremlin and the Monument to the Founder of this Museum in the Kremlin” (1898) and other works. The article considers N.F. Fyodorov’s analysis of paintings by A.A. Ivanov, N.N. Ge, V.V. Vereschagin, and I.E. Repin. The comparative investigation of the aesthetic program and artistic ideas of Ivanov and Fyodorov is based on the analysis of the painting “The Apparition of Christ before the People” (1858). The article traces the influence of the artist’s works on the conceptual and compositional creation of the “pictorial demonstration” of Fyodorov’s aesthetic supramoralism. It uncovers the specificity of the philosopher’s religious-philosophical discourse, defined by the iconographic traditions and imaginary system of Christian art. The analysis of Fyodorov’s texts dedicated to the paintings by Ge and Repin, reveals that he does not accept the aesthetic program of realism. The article defines the meaning of projective ecphrasis in Fyodorov’s critical account of Ge’s “Biblical cycle” as a theurgical project. The reception of Vereschagin’s painting is considered in the context of the historiosophical ideas of Fyodorov, based on the principles of Christian eschatology.
(A)morally Demanding Game? An Exploration of Moral Decision-Making in a Purpose-Made Video Game
Authors: Hodge Sarah E. , Taylor Jacqui , McAlaney John
Published: December 2019

A purpose-made video game was used to measure response time and moral alignment of in-game moral decisions, which were made by 115 undergraduate students. Overall, moral decisions took between 4–6 seconds and were mostly pro-social. Previous gameplay, in-game, and post-game experiences predicted in-game moral alignment. Real-life moral salience was not related to in-game decision-making. The implications of these results are discussed in the context of the demands of video games and in-game moral decision-making models.
Practices in Progress: The State of Reappraisal and Deaccessioning in Archives
Authors: Huggard Marcella , Jackson Laura Uglean
Published: December 2019

In the spring of 2017, the article authors conducted a survey of archival institutions in the United States and Canada regarding current reappraisal and deaccessioning practices. The first of its kind in the United States, the survey gathered quantitative data regarding how, why, and which archival repositories reappraise and deaccession. This article describes the survey method, questions asked, and data collected, and provides an analysis of the results. The authors sought to learn if resources influence these practices; what, if any, policies and guidelines exist locally; how the processes are carried out; how archivists perceive ethical concerns commonly associated with these practices; and what benefits and consequences result from reappraising and deaccessioning. They found that reappraising and deaccessioning are common practices throughout a variety of institutions and result in positive outcomes. However, misunderstanding remains about these practices, and institutions may not always be conducting these practices in an ethical and responsible manner.
