Carbon Nanotube-Poly(Vinylidene Fluoride) Composite Films for Strain-Sensing Applications
Authors: Kumar Gundati Sudheer , Vishnupriya D. , Antao Ralph , Patro T. Umasankar
Published: November 2017

Acid-functionalized carbon nanotube (fCNT)-poly (vinylidene fluoride) (PVDF) composite films with different CNT contents (0-0.5wt%) were prepared by melt-blending followed by compression molding. The electrical resistance (R) of the composite films under tensile loading was measured by a two-probe method using a custom made equipment connected to digital multimeter. The films (0.35 and 0.5wt% fCNT composites) showed exponential increases in R with displacement after attaining the elastic strain. Further, the change in resistance divided by resistance (ΔR/R) showed a linear increase with strain (ε). The slope of the linear region is found to be higher for 0.35wt% fCNT composite (5.4) as compared to 0.5wt% fCNT composite (3.4), indicating a better sensitivity in the former case. This may be due to less number of electrical conducting paths in case of 0.35fCNT composite. On account of the results obtained, the composites promise as potential candidates for strain sensing in health monitoring.

Published: November 2017

Hydrophobic textile is a type of smart fabrics. Some of it are commonly coated with small particles and finally treated by water repellent agent in terms of acquiring its hydrophobic property. This research describes how hydrophobic textile are formed from its initial form of fabrics and even yarn, which are fibers. Synthesis process was commenced through wet spinning of viscose rayon mixed with nanorod silica which has been formerly produced with sol gel method. These fibers were then coated with chitosan and dried out by vacuum instrument. Scanning Electron Microscopy (SEM) results showed that nanorod silica were well attached on the fibers. Followed by Energy Dispersive Spectroscopy (EDS) mapping characterization, silica particles were moderately dispersed on its surface, performing roughness and creating hydrophobic effect. In addition, several characterization methods correlated to water absorption of the fibers were conducted. Fibers swelling percentage decreased from 50.2% to 17.13%, while moisture regain (MR) number also decreased from 14.28 to 10.72.

Published: November 2017

In this paper, a series of milling tests were carried out in order to identify the effects of variable pitch on cutting temperature, cutting force and surface roughness while end milling the stainless steel 316L using Nitico30 and conventional cutting tools. Slot-milling operations were conducted. The value of feed rate were choose between the range recommended by the manufactured for the both conventional and Nitico30 cutting tool. The effect of variable pitch on cutting temperature, cutting forces and surface roughness were discussed. Results showed that the cutting temperature increase with the increase of feed rate for both cutting tool. Further increasing the speed of feed rate, the cutting forces also gradually increase for both cutting tool. However, the comparison between both cutting tools, it was found that the cutting temperature, cutting force and surface roughness improve about 47.8%, 37.5% and 17.6% respectively for Nitico30 cutting tool.

Published: November 2017

The substances move in conductors owing to drift of ions that occurs due to momentum exchange at collisions between the conductive carriers and atomic lattice. This effect is substantial at high-density direct currents, e.g., in power electronics. Therefore, the assigned subject matter is topical. The aim of this work is investigation of the effect of magnetic fields on electromigration processes of liquid inclusions in aluminum. We performed an analysis of formation and electromigration of molten Al-Si inclusions in silicon and aluminum crystals. It was found that molten inclusions 50-800 μm in size are formed in the studied system by contact melting in the 850-920 K temperature range. The electro-stimulated migration of inclusions along the electric lines of force at current densities j  4106 A/m2 was also established. From the dimensional dependence of specific velocity of travel w/j of molten Al-Si regions in silicon and aluminum, we made a conclusion concerning mechanisms of molten regions travelling. These are melting and crystallization at interphase boundaries due to thermoelectric phenomena and electromigration of atoms in the inclusion bulk. The numerical values of effective charges of Al and Si atoms in Al-Si melts as well as Peltier coefficients of the crystal-melt system were determined experimentally. It was found that preexposure of aluminum alloy (with iron concentration of ~0.6%) in a static magnetic field (В = 0.7 T) leads to changing of dimensional dependence of migration velocity of inclusions (i.e., it is magneto-sensing).
Psychosomatic Liaison Service in Cardiology
Authors: Fritzsche Kurt
Published: November 2017

Between 30 and 50% of inpatients treated in cardiology departments have emotional or psychosomatic problems that require psychotherapeutic information, consultation, as well as emotional support. This requirement can be effectively met by a liaison service with psychotherapists who are present on a regular basis and are integrated into the ward team. The psychotherapeutic interventions applied are focused on immediate solutions, the main goal of which is an improvement of the patient's capacity to cope emotionally with heart disease and the interpersonal problems arising from it. Important components of these interventions include the therapeutic relationship, active support in coping with problems, and resource activation. Evaluation of the psychosomatic liaison service by the cardiology nursing staff and doctors reveals a high degree of satisfaction with and acceptance of the liaison service.

Authors: Rodríguez-Blanco T. , Sarabia D. , De Prada C.
Published: November 2017

La gestión óptima de las plantas de proceso normalmente se lleva a cabo en una capa de optimización en tiempo real (Real Time Optimization, RTO) que actúa sobre la capa de control y que toma decisiones considerando objetivos económicos en base a un  modelo del proceso, normalmente estacionario. Sin embargo, dicha operación óptima no está garantizada debido a la presencia de incertidumbre entre el modelo usado para la toma de decisiones y el proceso real. Con la idea de conducir el proceso a su punto de operación óptimo usando un modelo que se sabe incierto o erróneo, surge la metodología de adaptación de modificadores (Modifier Adaptation o MA). En dicha metodología, el problema de optimización económica de la capa RTO es modificado mediante unos términos correctores, conocidos como modificadores, estimados a partir de medidas de la planta, con el objetivo de conducir el proceso a su punto de operación óptimo. El presente artículo hace una revisión de las técnicas desarrolladas hasta el momento dentro de la metodología MA analizando sus características y modos de implementación.

Published: November 2017

Los sistemas holónicos de manufactura son integrados por holones capaces de comportarse de una manera autónoma, cooperativa, auto-organizada y reconfigurable para adoptar estructuras distintas en condiciones de operación normales y de emergencia. Dichos holones cuentan con: (1) una representación del conocimiento, (2) una unidad de control distribuido y descentralizado, y (3) un módulo de coordinación. El objeto de interés de la presente investigación es la concepción de una ontología unificada en el dominio de manufactura, que garantice los requisitos en el formalismo del modelo de conocimiento de un sistema holónico. A diferencia de los modelos ontológicos encontrados en la literatura, el esquema de representación del conocimiento propuesto integra roles y comportamientos, mismos que son validados mediante un caso de estudio de una celda de manufactura de un laboratorio universitario. Los resultados muestran que al hacer uso de un vocabulario común, es posible representar coherentemente el conocimiento para que toda clase de holones en una holarquía puedan intercambiar, compartir y recuperar información.

Published: November 2017

Abstract. Rangelands which consist of grasslands, shrublands and savannahs are used by wildlife for habitat and are the main source of forage for livestock. The assessment and monitoring of rangeland condition is one of the most important factors for rangeland scientists in order to calculate the carrying capacity of livestock with consideration for coexisting wildlife. This study assessed the potential of Landsat 8 multispectral bands and broadband vegetation indices to model woody vegetation parameters such as tree equivalents (TE) and total leaf mass (LMASS) for the Thanda Private Game Reserve using partial least squares regression (PLSR). The PLSR model predicted TE with an R2 value of 0.76 and a root mean square error (RMSE) of 1411 TE/ha using an independent test dataset. LMASS was predicted with an R2 value of 0.67 and a RMSE of 853 kg/ha on an independent test dataset. The predictive models were then inverted to map TE and LMASS over the study area. The modelled TE and LMASS layers were integrated with conventional grazing and browse capacity models to map carrying capacity for the Game Reserve. The study indicates the potential of Landsat 8 multispectral data in carrying capacity modelling. The result is significant for rangeland monitoring in Southern Africa using remote sensing technologies.
HIGH RESOLUTION LANDCOVER MODELLING WITH PLÉIADES IMAGERY AND DEM DATA IN SUPPORT OF FINE SCALE LANDSCAPE THERMAL MODELLING

Abstract. In the evaluation of air-borne thermal infrared imaging sensors, the use of simulated spectral infrared scenery is a cost-effective way to provide input to the sensor. The benefit of simulated scenes includes control over parameters governing the spectral and related thermal behaviour of the terrain as well as atmospheric conditions. Such scenes need to have a high degree of radiometric and geometric accuracy, as well as high resolution to account for small objects having different spectral and associated thermal properties. In support of this, innovative use of tri-stereo, ultra-high resolution Pléiades satellite imagery is being used to generated high detail, small scale quantitative terrain surface data to compliment comparable optical data in order to produce detailed urban and rural landscape datasets representative of different landscape features, within which spectrally defined characteristics can be subsequently matched to thermal signatures. Pléiades tri-stereo mode, acquired from the same orbit during the same pass, is particularly favourable for reaching the required metric accuracy because images are radiometrically and geometrically very homogeneous, which allows a very good radiometric matching for relief computation. The tri-stereo approach reduces noise and allows significantly enhanced relief description in landscapes where simple stereo imaging cannot see features, such as in dense urban areas or valley bottoms in steep, mountainous areas. This paper describes the datasets that have been generated for DENEL over the Hartebeespoort Dam region, west of Pretoria, South Africa. The final terrain datasets are generated by integrated modelling of both height and spectral surface characteristics within an object-based modelling environment. This approach provides an operational framework for rapid and highly accurate mapping of building and vegetation structure of wide areas, as is required in support of the evaluation of thermal imaging sensors.
MOBILE ATMOSPHERIC SENSING
Authors: Wang L. , Huang Y.
Published: November 2017

Abstract. Atmospheric quality dramatically deteriorates over the past decades around themetropolitan areas of China. Due to the coal combustion, industrial air pollution, vehicle waste emission, etc., the public health suffers from exposure to such air pollution as fine particles of particulates, sulfur and carbon dioxide, etc. Many meteorological stations have been built to monitor the condition of air quality over the city. However, they are installed at fixed sites and cover quite a small region. The monitoring results of these stations usually do NOT coincide with the public perception of the air quality. This paper is motivated to mimic the human breathing along the citys transportation network by the mobile sensing vehicle of atmospheric quality. To obtain the quantitative perception of air quality, the Environmental Monitoring Vehicle of Wuhan University (EMV-WHU) has been developed to automatically collect the data of air pollutants. The EMV-WHU is equipped with GPS/IMU, sensors of PM2.5, carbon dioxide, anemometer, temperature, humidity, noise, and illumination, as well as the visual and infrared camera. All the devices and sensors are well collaborated with the customized synchronization mechanism. Each sort of atmospheric data is accompanied with the uniform spatial and temporal label of high precision. Different spatial and data-mining techniques, such as spatial correlation analysis, logistic regression, spatial clustering, are employed to provide the periodic report of the roadside air quality. With the EMV-WHU, constant collection of the atmospheric data along the Luoyu Road of Wuhan city has been conducted at the daily peak and non-peak time for half a year. Experimental results demonstrated that the EMV is very efficient and accurate for the perception of air quality. Comparative findings with the meteorological stations also show the intelligence of big data analysis and mining of all sorts of EMV measurement of air quality. It is promising for the aerial and emergent air quality monitoring over the sky of big cities, if EMV-WHU be miniaturized for the unmanned aerial vehicles(UAV) in the future.
MULTI-TEMPORAL SPATIAL DATA AFRICA
Authors: Becker R.
Published: November 2017

Abstract. To plan for the future, it is essential to understand the present as well as the past. Hindsight is the most valuable asset when examining how to proceed. Apart from natural catastrophes, conditions do not happen, they develop! This paper proposes that in order to change or influence conditions, not only must their present state be considered, but it is essential to investigate what triggered them in the first place. This requires access to records that might have to reach back for as much as many years. In Africa, such records are hard, if not impossible, to retrieve. Moreover, whatever records can be located are likely to have been compiled by a variety of different agencies, each presenting their own versions of events and consequently, often contradictory. To overcome such problems, it is proposed to use aerial photography that has been taken and hopefully archived over the past decades. Such aerial imagery can provide temporal geospatial data to trace the course, interaction and consequences of events. Combined with more recent satellite imagery, they provide unbiased evidence of past developments that can now be analyzed and assessed based on our awareness of today. This presentation deals with advanced data conversion and automated processing procedures conceived for convenient and user-friendly information access, as well as data mining and bigdata processing.
WETLAND HYDROLOGICAL INTEGRITY ASSESSMENT WITH UNMANNED AERIAL SYSTEMS (UAS)
Authors: Boon M. A. , Tesfamichael S.
Published: November 2017

Abstract. A key component of the health status of a wetland ecosystem is the present hydrological integrity. The analysis of on-site activities that impact on the hydrology of a particular wetland was undertaken using an Unmanned Aerial System (UAS) in combination with field studies. The WET-Health methodology was followed for the hydrological assessment, where wetland health is a measure of the deviation of a wetland’s structure and function from its natural reference condition. The extent and nature of activities within the wetland such as impoundments, excavations and indicators of visible damage such as erosion gullies was determined through high resolution UAS mapping using a commercial off-the-shelf digital camera. Structure from Motion (SfM) computer vision techniques were used to derive ultra-high resolution point clouds, orthophotos, digital elevation models (DEMs) and digital terrain models (DTMs). Visual and statistical analyses of the point clouds and surface models were used to derive detailed information useful for enhanced hydrological health assessment of the wetland. The WET-Health hydrology module completed with the aid of the UAS products still indicated that the hydrology of the wetland is completely modified as indicated by the “F” Present Ecological State (PES) category and that the hydrological state of the wetland will deteriorate (change score). However a higher impact score was determined through the enhanced visualisation and completion of scale-appropriate measurements of hydrological features. In conclusion, the use of UAS can significantly enhance the assessment of surface hydrology of wetlands and thereby allow for more effective management, decision making and conservation of wetland ecosystems.
DETERMINATION OF THE PRESENT VEGETATION STATE OF A WETLAND WITH UAV RGB IMAGERY
Authors: Boon M. A. , Tesfamichael S.
Published: November 2017

Abstract. The compositional and structural characteristics of wetland vegetation play a vital role in the services that a wetland supplies. Apart from being important habitats, wetland vegetation also provide services such as flood attenuation and nutrient retention. South Africa is known to be a water scarce country. The protection and continuous monitoring of wetland ecosystems is therefore important. Factors such as site transformation and disturbance may completely change the vegetation of a wetland and the use of Unmanned Aerial Vehicle (UAV) imagery can play a valuable role in high-resolution monitoring and mapping. This study assessed if the use of UAV RGB imagery can enhance the determination of the present vegetation state of a wetland. The WET-Health level two (detailed on-site evaluation) methodology was followed for the vegetation assessment, where wetland health is a measure of the deviation of a wetland’s structure and function from its natural reference condition. The mapping of the disturbances classes was then undertaken using ultra-high resolution orthophotos, point clouds and digital surface models (DSM). The WET-Health vegetation module completed with the aid of the UAV products still indicates that the vegetation of the wetland is largely modified (“D” PES Category) and that the vegetation of the wetland will further deteriorate (change score). These results are the same as determined in the baseline study. However a higher impact (activities taking place within the wetland) score were determined. The assessment of various WET-Health vegetation indicators were significantly enhanced using the UAV imagery and derived products. The UAV products provided an accurate vantage point over the wetland and surroundings, and assisted to easily refine the assessment of the disturbance classes and disturbance units.
Concept for a MEMS-type vacuum sensor based on electrical conductivity measurements
Authors: Giebel Friederike Julia , Köhle Marcel , Stramm Till , Kallis Klaus T. , Fiedler Horst L.
Published: November 2017

Abstract. The concept of the micro-structured vacuum sensor presented in this article is the measurement of the electrical conductivity of thinned gases in order to develop a small, economical and quite a simple type of vacuum sensor. There are already some approaches for small vacuum sensors. Most of them are based on conservative measurement principles similar to those used in macroscopic vacuum gauges. Ionization gauges use additional sources of energy, like hot cathodes, ultraviolet radiation or high voltage for example, for ionizing gas molecules and thereby increasing the number of charge carriers for measuring low pressures. In contrast, the concept discussed here cannot be found in macroscopic sensor systems because it depends on the microscopic dimension of a gas volume defined by two electrodes. Here we present the concept and the production of a micro-structured vacuum sensor chip, followed by the electrical characterization. Reference measurements with electrodes at a distance of about 1 mm showed currents in the size of picoampere and a conductivity depending on ambient pressure. In comparison with these preliminary measurements, fundamental differences regarding pressure dependence of the conductivity are monitored in the electrical characterization of the micro-structured sensor chip. Finally the future perspectives of this sensor concept are discussed.
Quasi static ensemble variational data assimilation
Authors: Fillion Anthony , Bocquet Marc , Gratton Serge
Published: November 2017

Abstract. The analysis in nonlinear variational data assimilation is the solution of a non-quadratic minimization. Thus, the analysis efficiency relies on its ability to locate a global minimum of the cost function. If this minimization uses a Gauss-Newton (GN) method, it is critical for the starting point to be in the attraction basin of a global minimum. Otherwise the method may converge to a local extremum, which degrades the analysis. With chaotic models, the number of local extrema often increases with the temporal extent of the data assimilation window, making the former condition harder to satisfy. This is unfortunate because the assimilation performance also increases with this temporal extent. However, a quasi-static (QS) minimization may overcome these local extrema. It consists in gradually injecting the observations in the cost function. This method was introduced by Pires et al. (1996) in a 4D-Var context. We generalize this approach to four-dimensional nonlinear EnVar methods, which are based on both a nonlinear variational analysis and the propagation of dynamical error statistics via an ensemble. This forces to consider the cost function minimizations in the broader context of cycled data assimilation algorithms. We adapt this QS approach to the iterative ensemble Kalman smoother (IEnKS), an exemplar of nonlinear deterministic 4D EnVar methods. Using low-order models, we quantify the positive impact of the QS approach on the IEnKS, especially for long data assimilation windows. We also examine the computational cost of QS implementations and suggest cheaper algorithms.
Characteristics of high monsoon wind-waves observed at multiple stations in the eastern Arabian Sea
Authors: Amrutha M. M. , Sanil Kumar V.
Published: November 2017

Abstract. The growth and decay of surface wind-waves during one-month period in a typical Indian summer monsoon is investigated based on the data collected at 9 to 15 m water depth at 4 locations in the nearshore waters of the eastern Arabian Sea covering a spatial distance of ~ 350 km. The significant wave height varied from 0.7 to 5.5 m during the data collection considered in the analysis. The heights of waves during the measurement period often exceed 3 m. The most extreme wave height is 1.50 to 1.62 times the significant wave height and the most extreme crest height of the wave is 1.23 to 1.35 times the significant wave height of the same 30-minutes record. The average ratio of crest height of the wave to the height of the same wave is 0.58 to 0.67. The height of waves having maximum crest height is smaller than the maximum wave height during 30 minutes period. Measured waves are predominantly swell, but since the majority of wave generation during the monsoon is adjacent to the study area and the wind–wave coupling is strong, wave periods are rarely above 15 s. The numerical wave model could estimate the wave height reasonably well during the wave growth compared to the wave decay period. Hovmöller diagrams show a considerable spatial variability in the wave and wind pattern in the Indian Ocean during the high wave event at the eastern Arabian Sea.

Published: November 2017

The goal of this research was to investigate children’s recall of optional and obligatory elements of a script-based story as the retention period increased. Typically developing children, 20 kindergarteners and 20 second graders, participated. Children were asked to retell a story immediately after exposure to it, as well as one week post-, and two weeks post-exposure. Findings provide evidence that children of both age groups were able to marshal their script knowledge to recall stories over time. Older children were able to recall more elements and more of both, obligatory and optional elements, than younger children across all recall attempts.

This research empirically examines the mediating role of organizational trust on human resource management, and affective commitment. An independent variable may not provide the significant effect on a dependable variable whereas, the effect may be found significant through a third variable or indirect relationship. Thus, the research paradigm is determining the function of indirect variable whether it role as a full mediator or a partial mediator in the relationship analysis. The study is based on human resource management, employee psychology and organizational behavior literature, hypotheses were tested by using Baron and Kenny’s mediating analysis. The study reported mixed results on research key variables. Theoretically, the study contributes to conceptualized human resource management practices affective commitment and organizational trust theory. It also provides practitioners’ implications and awareness that lack of organizational trust, employee affective commitment might be reduced and management can be failure to accomplish organizational success and managerial acumen.

Published: November 2017

The sugarcane sector has been gaining more importance in both Brazilian and World economies, even though it has had a lack of agricultural investments and climate issues has generated questionings about the future of the sector. To analyse this trend, the present work was based on the following growth strategies: internal growth, horizontal integration, diversification, and vertical integration. The objective of the present research is to assess the relationship between these types of strategies and macro-environmental variables in order to determine any possible correlation. Bibliographic and documental survey on the behaviour of macro-environment variables was carried out. The Pearson’s correlation test was used to identify the relationship between these variables and growth strategies. It was possible to observe that each type of growth strategy is related to one specific type of variable, which is exclusive to each strategy, except in the case of diversification. That is, electric energy prices have a correlation with internal growth and the real growth rate is correlated with horizontal growth. None of these macro-environmental variables repeated in other growth strategies. The only exception was the diversification strategy, which was correlated with eight variables, with five of these being exclusive to this type of strategy.

Authors: Chow Yee Peng , Muhammad Junaina , Amin Noordin Bany Ariffin , Cheng Fan Fah
Published: November 2017

This paper examines the historical pattern of macroeconomic uncertainty of two developing countries in the South East Asia, namely Malaysia and Indonesia. Comparisons of macroeconomic uncertainty are also made between both countries using a selected number of indicators for macroeconomic volatility. We find that while both countries were affected by similar external sources of macroeconomic uncertainty, these countries were also subject to domestic sources of macroeconomic uncertainty which were confined to the particular country. The analyses also reveal that Indonesia experienced more fluctuations compared to Malaysia when macroeconomic uncertainty is measured by volatility as a macroeconomic outcome and domestic sources of macroeconomic volatility. Contrarily, Malaysia displayed greater fluctuations than Indonesia when macroeconomic uncertainty is measured by external sources of macroeconomic volatility. Policy implications are drawn from the findings.

As an example, we demonstrate the exact math and Matlab methodology to match a Taxpayer and money beneficiary with scoreboard 65 non-zero diagram points. The working system could be useful for Financial Intelligent Units, Economic Law enforcement agencies and Immigration Authorities.
Will Inequality Affect Growth?: Evidence from USA and China since 1980
Authors: Wang Yongqing
Published: November 2017

Income inequality may hinder economic growth is a widespread concern. The results from previous literature are mixed. Although both USA and China is an excellent case study by itself, it is even interesting to compare them given they are the two largest economies in the world, and yet completely different from each other. We employ annual data from 1980 to 2012 and apply cointegration to study the effects of income inequality on real GDP per capita and real GDP of both USA and China. We also include the exchange rate into the model to examine possible effects of depreciation on growth. The main findings are: first, depreciation does not affect the growth of USA. Second, depreciation promotes growth of China in the short-run, but may hurt its growth in the long-run. Third, income inequality will hurt growth of USA in the short-run, while it encourages its growth in the long-run. Finally, income inequality may promote growth of China in both short-run and long-run.
Consequences of Seed Priming with Salicylic Acid and Hydro Priming on Smooth Vetch Seedling Growth under Water Deficiency
Authors: Namdari Amin , Baghbani Abolfazl
Published: November 2017

Due to low rainfall at early autumn, smooth vetch seedling growth in rain-fed lands often is limited by water deficit stress yet the data regarding the reactions of smooth vetch to water deficit at early growth stages are pretty rare. The objective of current study was to examine possibility of using priming treatments (hydro priming and priming salicylic acid) to alleviate the inhibitory effect of water deficiency during early growth of Smooth Vetch. In this respect, seeds were soaked in distilled water (hydro priming) or 0.5 mM solution of SA for 36 h at 10 °C then dried back to original moisture content. Pots were irrigated for 25 days at four levels of available water containing field capacity (FC), 75% FC, 50% FC and 25% FC. In general, seedling emergence and early growth were markedly limited by increasing water deficiency. However, priming treatments particularly with SA caused considerable improvement in either emergence or growth of seedlings (dry weight, length). The obtained results showed that primed samples exhibited higher accumulation of proline, glycine betaine (GB) under all levels of available water except 100% FC and also higher total soluble sugars (TSS) and trehalose under severe water deficit (25% FC). SA primed samples had higher relative water content especially under higher levels of water deficiency. The more balanced water status within SA primed samples also was accompanied with higher accumulation of proline and glycine betaine. There were significant differences between two priming treatments in terms of proline and GB content within seedlings and SA priming considerably increased proline and GB accumulation. In contrast to proline and GB, TSS and trehalose content wasn’t influenced by SA treatment and both hydro and SA primed samples showed statistically similar quantities.

Resumo

O artigo examina os romances A chave de casa, de Tatiana Salem Levy e Opisanie Swiata, de Veronica Stigger, duas obras recentes da Literatura Brasileira cujo foco é o deslocamento de protagonistas que previamente já passaram pela experiência de desenraizamento. As narrativas salientam a necessidade de uma nova viagem para os dois personagens. No primeiro romance o avô da protagonista sugere a ela que vá até a sua casa em Esmirna, Turquia, entregando-lhe a chave da porta da frente da residência. Na segunda obra, Natanael, filho brasileiro do protagonista polonês solicita a ele, através de carta, uma visita em seu leito de morte, o que faz o pai, Opalka, vir de navio da Europa até a América do Sul. No entanto o propósito das viagens é alterado ainda antes do destino final. Os protagonistas têm seus objetivos iniciais frustrados, mas também experimentam uma epifania causada pelo próprio ato de se deslocar. Descobrem-se pessoas diferentes daquelas que iniciaram a viagem. Essa experiência é uma clara ilustração do que defende Michel Onfray no seu Teoria da viagem:  “a viagem nos faz saber de nós mesmos”. (p. 75).  Ir à Esmirna e à Amazônia brasileira é uma forma tanto de intensificar quanto de amenizar as feridas do exílio anterior que nunca poderão ser, de fato, esquecidas. É, acima de tudo, uma tentativa de reconexão, de profunda ligação consigo mesmo, com a família e a sociedade ao redor. 
O romance A casa da água e a representação dos afro-brasileiros na África em finais do século XIX
Authors: Pereira Édimo De Almeida
Published: November 2017

RESUMO:  No ano de [1889]1900 ocorreu a viagem de retorno da ex-escravizada africana Catarina Pereira Chaves, e de seus familiares brasileiros à cidade nigeriana de Lagos. Esta viagem foi recriada pelo escritor Antonio Olinto, nas linhas do romance A casa da água (1988).  Nesta obra, a narrativa da experiência de brasileiros descendentes de ex-escravizados, na condição de estrangeiros na África, envolve temáticas como a estranheza, a hospitalidade e os conflitos decorrentes do ingresso desses indivíduos na ordem social, política e econômica das cidades da Costa dos Escravos, de onde anteriormente haviam sido trasladados, durante a diáspora, os seus ascendentes. Em Lagos, a comunidade brasileira organizou-se em torno dos seus grandes homens, negociantes ricos com quem se abasteciam e de quem dependiam as famílias mais desfavorecidas, constituindo uma rede de clientela, cujo sentido de unidade veio a resultar na organização e na ocupação de um bairro brasileiro denominado Brazilian Quarter. Nesse sentido, abordamos  a relação entre os afro-brasileiros e os africanos que os receberam, sob o ponto de vista do binômio estranheza/hospitalidade. Tal abordagem se dá com base nos apontamentos de Jacques Derrida, a partir das noções de hospitalidade e de “hos-ti-pitalidade”, termo criado pelo filósofo para se referir às circunstâncias em que a hospitalidade é pervertida pela hostilidade. Com base nesses elementos, a partir da narrativa da mencionada obra olintiana, discorremos sobre os percursos de brasileiros na cidade de Lagos.
Trânsitos e vivências nos romances de Mia Couto
Authors: De Brito Daniela
Published: November 2017

O que caracteriza o lugar da identidade na obra de Mia Couto é a viagem, visto que seus romances, geralmente, encenam a pluralidade de etnias, crenças, idiomas, devido à multiplicidade decorrente de trocas contínuas, realizadas ao longo do período de colonização e descolonização de Moçambique. A proposta deste artigo é investigar três romances desse autor, com a finalidade de verificar como os deslocamentos se interligam à questão da identidade, atentando para a configuração da personagem estrangeira como viajante, cujo deslocamento espacial e contato com o outro promovem trânsitos que podem, ou não, desalojá-lo da posição de estrangeiro, e também para as que são originárias do país, mas vistas como estrangeiras por seus conterrâneos.
THERMAL EXPANSION AND ELECTRICAL PROPERTIES OF Bi2Ca2O5, Bi2CaO4 AND Bi24Co2O39 DOUBLE OXIDES
Authors: Klyndyuk Andrey I. , Krasutskaya Natalie S.

Bi2Ca2O5, Bi2CaO4 and Bi24Co2O39 double oxides are of interest as intermediate phases at preparation of Bi2Ca2Co1,7Oy and (Ca,Bi)3Co4O9+d oxide thermoelectrics and as admixtures to the heterogeneous ceramics based on these layered oxides. In this work Bi2Ca2O5, Bi2CaO4, and Bi24Co2O39 ceramic samples were prepared using solid-state reactions method from Bi2O3, CaCO3, and Co3O4 in air within the temperature range of 923–1143 K. The crystal structure of the samples was studied by X-ray diffraction (XRD) analysis using Bruker D8 XRD Advance with monochromatic CuKa radiation (l = 1.5406 Å). Thermal expansion, electrical conductivity (s), dielectric permittivity (e) and dielectric losses (tgd) of ceramics were studied in air in the temperature range of 290–1070 K. Bi2Ca2O5 crystallizes in the triclinic system (a = 1.01(2) nm, b = 1.01(5) nm, c = 1.05 nm, a = 116.9(1)°, b = 107.14(3)°, g = 92.89°, V = 0.890 nm3, ρXRD = 6.47 g/cm3), Bi2CaO4 - in the monoclinic one (a = 1.664(7) nm, b = 1.162(1) nm, c = 1.402(7) nm, b = 134.17(2)°, V = 1.945(26) nm3, ρXRD = 7.13 g/cm3), and Bi24Co2O39 - in the cubic one (a = 1.021(1) nm, V = 1.063(16) nm3, ρXRD = 9.00 g/cm3). Apparent density values of the sintered ceramics are 5.78, 4.82, and 7.42 g/cm3 for Bi2Ca2O5, Bi2CaO4, and Bi24Co2O39 compounds, respectively. It was found that electrical conductivity of the materials studied had semiconducting character, and increasing in the bismuth oxide content in ceramics leads to the increasing its electrical conductivity, dielectric permittivity, and dielectric losses values. The values of average linear thermal expansion coeffient are equal to 12.9×10–6, 14.7×10–6, and 16.0×10–6 K–1. Activation energy of electrical conductivity are equal to 1.393, 1.159, and 0.499 eV, and temperature of maximum of dielectric losses due to dipole polarization are equal to 923, 780, and 681 К for the Bi2Ca2O5, Bi2CaO4, and Bi24Co2O39 ceramics, respectively. On the temperature dependence of dielectric permittivity of Bi24Co2O39 phase the local maximum at 845 K was detected, which is connnected, obviously, to the partial disordering of dipoles in its crystal structure.Forcitation:Klyndyuk A.I., Krasutskaya N.S.

INFLUENCE OF HEXAMETHYLPHOSPHOTRIAMIDE MOLECULES ON WATER STRUCTURE
Authors: Zheleznyak Nikolay I.
Published: November 2017

The volume-manometric method was used to measure the solubility of noble gases: helium, argon, and krypton in mixtures of water with HMPA in the region of small additions of the organic component at temperatures of 283.15; 298.15 and 313.15 K. The maximum on the solubility curves is explained by the competing effect of the hydrophobic and hydrophilic hydration of the corresponding fragments of HMPA molecules. The "bond-breaking" model of water was used in the present work. According to this model the possible deformations of the hydrogen bonds are neglected. It makes possible to calculate the fractions of water molecules participating in any number of hydrogen bonds at the specified temperature. The phenomenological model of the structure of HMPA aqueous solutions is presented. On the base of experimental solubility of gases and the permittivity of solutions, it is possible to calculate the structural characteristics of diluted aqueous solutions. In the frame of the model one can determine the contribution of the effects of hydrophobic hydration to the total energy of interactions in the water-non-electrolyte system and describe the changes in water structure in aqueous solutions. It was found that at x = 0.0035 mole fraction of HMPA, there is an increase in the number of water molecules participating in four hydrogen bonds without changing the average number of hydrogen bonds per water molecule. At x = 0.005 the properties of the system are already largely determined by the influence of the polar group (P = O) of the HMPA molecule. At x = 0.0101 additions of the organic component to water lead to the redistribution of H-bonds and have to the same consequences as the increase in temperature from 298.15 to 313.15 K.Forcitation:Zheleznyak N.I.
