Development of a Numerical Model for a Compact Intensified Heat-Exchanger/Reactor
Authors: He Menglin , Li Zetao , Han Xue , Cabassud Michel , Dahhou Boutaib
Published: July 2019

A heat-exchanger/reactor (HEX reactor) is a kind of plug-flow chemical reactor which combines high heat transfer ability and chemical performance. It is a compact reactor designed under the popular trend of process intensification in chemical engineering. Previous studies have investigated its characteristics experimentally. This paper aimed to develop a general numerical model of the HEX reactor for further control and diagnostic use. To achieve this, physical structure and hydrodynamic and thermal performance were studied. A typical exothermic reaction, which was used in experiments, is modeled in detail. Some of the experimental data without reaction were used for estimating the heat transfer coefficient by genetic algorithm. Finally, a non-linear numerical model of 255 calculating modules was developed on the Matlab/Simulink platform. Simulations of this model were done under conditions with and without chemical reactions. Results were compared with reserved experimental data to show its validity and accuracy. Thus, further research such as fault diagnosis and fault-tolerant control of this HEX reactor could be carried out based on this model. The modeling methodology specified in this paper is not restricted, and could also be used for other reactions and other sizes of HEX reactors.

Authors: de Gosson Maurice , Luef Franz
Published: July 2019

The usual Poisson bracket { A , B } can be identified with the so-called Moyal bracket { A , B } M for larger classes of symbols than was previously thought, provided that one uses the Born–Jordan quantization rule instead of the better known Weyl correspondence. We apply our results to a generalized version of Ehrenfest’s theorem on the time evolution of averages of operators.
An Analog Interface Circuit for Capacitive Angle Encoder Based on a Capacitance Elimination Array and Synchronous Switch Demodulation Method
Authors: Hou Bo , Zhou Bin , Li Xiang , Gao Zhenyi , Wei Qi , Zhang Rong
Published: July 2019

This paper presents an analog interface application-specific integrated circuit (ASIC) for a capacitive angle encoder, which is widely used in control machine systems. The encoder consists of two parts: a sensitive structure and analog readout circuit. To realize miniaturization, low power consumption, and easy integration, an analog interface circuit including a DC capacitance elimination array and switch synchronous demodulation module was designed. The DC capacitance elimination array allows the measurement circuit to achieve a very high capacitance to voltage conversion ratio at a low supply voltage. Further, the switch synchronous demodulation module effectively removes the carrier signal and greatly reduces the sampling rate requirement of the analog-to-digital converter (ADC). The ASIC was designed and fabricated with standard 0.18 µm CMOS processing technology and integrated with the sensitive structure. An experiment was conducted to test and characterize the performance of the proposed analog interface circuit. The encoder measurement results showed a resolution of 0.01°, power consumption of 20 mW, and accuracy over the full absolute range of 0.1°, which indicates the great potential of the encoder for application in control machine systems.

Authors: Zhang Zequn , Fu Kun , Sun Xian , Ren Wenjuan
Published: July 2019

In multi-sensor fusion (MSF), the integration of multi-sensor observation data with different observation errors to achieve more accurate positioning of the target has always been a research focus. In this study, a modified ensemble Kalman filter (EnKF) is presented to substitute the traditional Kalman filter (KF) in the multiple hypotheses tracking (MHT) to deal with the high nonlinearity that always shows up in multiple target tracking (MTT) problems. In addition, the multi-source observation data fusion is also realized by using the modified EnKF, which enables the low-precision observation data to be corrected by high-precision observation data, and the accuracy of the corrected data can be calibrated by the statistical information provided by the EnKF. Numerical studies are given to demonstrate the effectiveness of our proposed method and the results show that the MHT-EnKF method can achieve remarkable enhancement in dealing with nonlinear movement variation and positioning accuracy for MTT problems in MSF scenario.

Authors: Zhang Zhe , Shang Huiqing , Wang Huaiwen , Zhang Qiumei , Yu Susu , Wu Qiaoyan , Tian Jinjin
Published: July 2019

Firmness changes in Nanguo pears under different freezing/thawing conditions have been characterized by hyperspectral imaging (HSI). Four different freezing/thawing conditions (the critical temperatures, numbers of cycles, holding time and cooling rates) were set in this experiment. Four different pretreatment methods were used: multivariate scattering correction (MSC), standard normal variate (SNV), Savitzky-Golay standard normal variate (S-G-SNV) and Savitzky-Golay multiplicative scattering correction (S-G-MSC). Combined with competitive adaptive reweighted sampling (CARS) to identify characteristic wavelengths, firmness prediction models of Nanguo pears under different freezing/thawing conditions were established by partial least squares (PLS) regression. The performance of the firmness model was analyzed quantitatively by the correlation coefficient (R), the root mean square error of calibration (RMSEC), the root mean square error of prediction (RMSEP) and the root mean square error of cross validation (RMSECV). The results showed that the MSC-PLS model has the highest accuracy at different cooling rates and holding times; the correlation coefficients of the calibration set (Rc) were 0.899 and 0.927, respectively, and the correlation coefficients of the validation set (Rp) were 0.911 and 0.948, respectively. The accuracy of the SNV-PLS model was the highest at different numbers of cycles, and the Rc and the Rp were 0.861 and 0.848, respectively. The RMSEC was 65.189, and the RMSEP was 65.404. The accuracy of the S-G-SNV-PLS model was the highest at different critical temperatures, with Rc and Rp values of 0.854 and 0.819, respectively, and RMSEC and RMSEP values of 74.567 and 79.158, respectively.
A Framework for an Intelligent and Personalized Fire Evacuation Management System
Authors: Zhang Jinyue , Guo Jianing , Xiong Haiming , Liu Xiangchi , Zhang Daxin
Published: July 2019

Many research studies have focused on fire evacuation planning. However, because of the uncertainties in fire development, there is no perfect solution. This research proposes a fire evacuation management framework which takes advantage of an information-rich building information modeling (BIM) model and a Bluetooth low energy (BLE)-based indoor real-time location system (RTLS) to dynamically push personalized evacuation route recommendations and turn-by-turn guidance to the smartphone of a building occupant. The risk score (RS) for each possible route is evaluated as a weighted summation of risk level index values of all risk factors for all segments along the route, and the route with the lowest RS is recommended to the evacuee. The system will automatically re-evaluate all routes every 2 s based on the most updated information, and the evacuee will be notified if a new and safer route becomes available. A case study with two testing scenarios was conducted for a commercial office building in Tianjin, China, in order to verify this framework.
Not a Security Issue: How Policy Experts De-Politicize the Climate Change–Migration Nexus
Authors: Honarmand Ebrahimi Sanaz , Ossewaarde Marinus
Published: July 2019

Policy experts play an important role in coping with the climate change–human migration nexus. They offer expert solutions to decision makers, and thus, they contribute to de-politicizing the issue. The aim of this paper is to find out how different policy experts envision the climate change–human migration nexus. The Netherlands has been nominated as the seat of a Global Center of Excellence for climate Adaptation and aims to become a Global Center of Excellence in the water safety and security domain. Policy experts were selected based on a structured nominee process. We conducted semistructured interviews with policy experts and analyzed policy expert documentation. Interview transcripts and documents were examined via a coding frame. Unlike policymakers who link climate change and conflict, policy experts stress the economic and political factors of migration in which climate change issues happen. The major difference between the view of policymakers and policy experts on the link between climate change and human migration emerges from the frame of the climate refugee. In the context of the climate change–human migration nexus, policy experts act as a countervailing power that prevents the political exploitation of the nexus into a security issue.
Stories of Favourite Places in Public Spaces: Emotional Responses to Landscape Change
Authors: Riechers Maraja , Henkel Werner , Engbers Moritz , Fischer Joern
Published: July 2019

Understanding emotions is necessary to analyse underlying motivations, values and drivers for behaviours. In landscapes that are rapidly changing, for example, due to land conversion for intensive agriculture, a sense of powerlessness of the inhabitants can be common, which may negatively influence their emotional bond to the landscape they are living in. To uncover varied emotional responses towards landscape change we used an innovative approach that combined transdisciplinary and artistic research in an intensively farmed landscape in Germany. In this project, we focused on the topic of favourite places in public spaces, and how change in such places was experienced. Drawing on workshops and interviews, we identified themes of externally driven societal and internal personal influences on the public favourite places. “Resilient” emotional responses towards landscape change showed a will to integrate the modifications, while “non-resilient” responses were characterised by frustration and despair. We argue that identifying emotions towards change can be valuable to strengthen adaptive capacity and to foster sustainability.
Etch Characteristics and Morphology of Al2O3/TiO2 Stacks for Silicon Surface Passivation
Authors: Suh Dongchul
Published: July 2019

Chemical processes are very important for the development of high-efficiency crystalline solar cells, mainly for surface texturing to improve light absorption and cleaning processes to reduce surface recombination. Recently, research has been focusing on the impact of chemical polishing on the performance of a passivated emitter and rear cells (PERC), with particular emphasis on the dielectric passivation layers on the front side. This study examined the influence of etching on the passivation of Al2O3/TiO2 stacks, where the films may each be deposited using a range of deposition and post-annealing parameters. Most TiO2 films deposited at 300 °C were resistant to chemical etching, and higher temperature deposition and annealing produced more chemical-resistant films. TiO2 films deposited at 100 °C were etched slightly by SC1 and SC2 solutions at room temperature, whereas they were etched at a relatively high rate in an HF solution, even when capped with a thick TiO2 layer (up to 50 nm in thickness); blistering occurred in 20-nm-thick Al2O3 films. In contrast to the as-deposited films, the annealed films showed a lower level of passivation as 1% HF etching proceeded. The implied open circuit voltage of the samples annealed at 300 °C after HF etching decreased more than those annealed at 400 °C. The dark area in the photoluminescence images was not resistant to the HF solution and showed more etch pits. The etching strategies developed in this study are expected to help setup integration processes and increase the applicability of this stack to solar cells.
Tight Bounds on 1-Harmonious Coloring of Certain Graphs
Authors: Liu Jia-Bao , Arockiaraj Micheal , Nelson Antony
Published: July 2019

Graph coloring is one of the most studied problems in graph theory due to its important applications in task scheduling and pattern recognition. The main aim of the problem is to assign colors to the elements of a graph such as vertices and/or edges subject to certain constraints. The 1-harmonious coloring is a kind of vertex coloring such that the color pairs of end vertices of every edge are different only for adjacent edges and the optimal constraint that the least number of colors is to be used. In this paper, we investigate the graphs in which we attain the sharp bound on 1-harmonious coloring. Our investigation consists of a collection of basic graphs like a complete graph, wheel, star, tree, fan, and interconnection networks such as a mesh-derived network, generalized honeycomb network, complete multipartite graph, butterfly, and Benes networks. We also give a systematic and elegant way of coloring for these structures.
Topologically Protected Duality on The Boundary of Maxwell-BF Theory
Authors: Blasi Alberto , Maggiore Nicola
Published: July 2019

The Maxwell-BF theory with a single-sided planar boundary is considered in Euclidean four-dimensional spacetime. The presence of a boundary breaks the Ward identities, which describe the gauge symmetries of the theory, and, using standard methods of quantum field theory, the most general boundary conditions and a nontrivial current algebra on the boundary are derived. The electromagnetic structure, which characterizes the boundary, is used to identify the three-dimensional degrees of freedom, which turn out to be formed by a scalar field and a vector field, related by a duality relation. The induced three-dimensional theory shows a strong–weak coupling duality, which separates different regimes described by different covariant actions. The role of the Maxwell term in the bulk action is discussed, together with the relevance of the topological nature of the bulk action for the boundary physics.
Hysteretically Symmetrical Evolution of Elastomers-Based Vibration Isolators within α-Fractional Nonlinear Computational Dynamics
Authors: Nastac Silviu , Debeleac Carmen , Vlase Sorin
Published: July 2019

This study deals with computational analysis of vibration isolators’ behavior, using the fractional-order differential equations (FDE). Numerical investigations regarding the influences of α-fractional derivatives have been mainly focused on the dissipative component within the differential constitutive equation of rheological model. Two classical models were considered, Voigt-Kelvin and Van der Pol, in order to develop analyses both on linear and nonlinear formulations. The aim of this research is to evaluate the operational capability, provided by the α-fractional derivatives within the viscous component of certain rheological model, to enable an accurate response regarding the realistic behavior of elastomeric-based vibration isolators. The hysteretic response followed, which has to be able to assure the symmetry of dynamic evolution under external loads, and at the same time, properly providing dissipative and conservative characteristics in respect of the results of experimental investigations. Computational analysis was performed for different values of α-fractional order, also taking into account the integer value, in order to facilitate the comparison between the responses. The results have shown the serviceable capability of the α-fractional damping component to emulate, both a real dissipative behavior, and a virtual conservative characteristic, into a unitary way, only by tuning the α-order. At the same time, the fractional derivative models are able to preserve the symmetry of hysteretic behavior, comparatively, e.g., with rational-power nonlinear models. Thereby, the proposed models are accurately able to simulate specific behavioral aspects of rubber-like elastomers-based vibration isolators, to the experiments.
Phobalysin: Fisheye View of Membrane Perforation, Repair, Chemotaxis and Adhesion
Authors: von Hoven Gisela , Rivas Amable J. , Husmann Matthias
Published: July 2019

Phobalysin P (PhlyP, for photobacterial lysin encoded on a plasmid) is a recently described small β-pore forming toxin of Photobacterium damselae subsp. damselae (Pdd). This organism, belonging to the family of Vibrionaceae, is an emerging pathogen of fish and various marine animals, which occasionally causes life-threatening soft tissue infections and septicemia in humans. By using genetically modified Pdd strains, PhlyP was found to be an important virulence factor. More recently, in vitro studies with purified PhlyP elucidated some basic consequences of pore formation. Being the first bacterial small β-pore forming toxin shown to trigger calcium-influx dependent membrane repair, PhlyP has advanced to a revealing model toxin to study this important cellular function. Further, results from co-culture experiments employing various Pdd strains and epithelial cells together with data on other bacterial toxins indicate that limited membrane damage may generally enhance the association of bacteria with target cells. Thereby, remodeling of plasma membrane and cytoskeleton during membrane repair could be involved. In addition, a chemotaxis-dependent attack-and track mechanism influenced by environmental factors like salinity may contribute to PhlyP-dependent association of Pdd with cells. Obviously, a synoptic approach is required to capture the regulatory links governing the interaction of Pdd with target cells. The characterization of Pdd’s secretome may hold additional clues because it may lead to the identification of proteases activating PhlyP’s pro-form. Current findings on PhlyP support the notion that pore forming toxins are not just killer proteins but serve bacteria to fulfill more subtle functions, like accessing their host.
Compact Star Properties from an Extended Linear Sigma Model
Authors: Takátsy János , Kovács Péter , Szép Zsolt , Wolf György
Published: July 2019

The equation of state provided by effective models of strongly interacting matter should comply with the restrictions imposed by current astrophysical observations of compact stars. Using the equation of state given by the (axial-)vector meson extended linear sigma model, we determine the mass–radius relation and study whether these restrictions are satisfied under the assumption that most of the star is filled with quark matter. We also compare the mass–radius sequence with those given by the equations of state of somewhat simpler models.

Authors: Santos Regina Maria Bessa , Sanches Fernandes Luís Filipe , Vitor Cortes Rui Manuel , Leal Pacheco Fernando António
Published: July 2019

The study area used for this study was the Sabor river basin (located in the Northeast of Portugal), which is composed mostly for agroforestry. The objectives were to analyze the spatiotemporal dynamics of hydrological services that occurred due to land use changes between 1990 and 2008 and to consider two scenarios for the year 2045. The scenarios were, firstly, afforestation projection, proposed by the Regional Plan for Forest Management, and secondly, wildfires that will affect 32% of the basin area. In this work, SWAT (Soil and Water Assessment Tool) was used to simulate the provision of hydrological services, namely water quantity, being calibrated for daily discharge. The calibration and validation showed a good agreement for discharge with coefficients of determination of 0.63 and 0.8 respectively. The land use changes and the afforestation scenario showed decreases in water yield, surface flow, and groundwater flow and increases in evapotranspiration and lateral flow. The wildfire scenario, contrary to the afforestation scenario, showed an increase in surface flow and a decrease in lateral flow. The Land Use and Land Cover (LULC) changes in 2000 and 2006 showed average decreases in the water yield of 91 and 52 mm·year−1, respectively. The decrease in water yield was greater in the afforestation scenario than in the wildfires scenario mainly in winter months. In the afforestation scenario, the large decrease varied between 28 hm3·year−1 in October and 62 hm3·year−1 in January, while in the wildfires scenario, the decrease was somewhat smaller, varying between 15 hm3·year−1 in October and 49 hm3·year−1 in January.

Published: July 2019

Large amounts of microplastics (MPs) enter our environment through runoff from urban areas. This study presents results for MPs in stormwater from a wet retention pond in terms of its water, sediments, and vertebrate fauna. The analysis was done for the size range 10–500 μm, applying a focal-plane array-based µFourier transform infrared (FPA-µFTIR) imaging technique with automated data analysis. Sample preparation protocols were optimized towards this analytical method. The study revealed 270 item L−1 in the pond water, corresponding to 4.2 µg L−1. The MPs in the pond were highly concentrated in its sediments, reaching 0.4 g kg−1, corresponding to nearly 106 item kg−1. MPs also accumulated in vertebrates from the pond—three-spined sticklebacks and young newts. In terms of particle numbers, this accumulation reached levels nearly as high as in the sediments. The size of the MPs in the pond water and its fauna was quite similar and significantly smaller than the MPs in the sediments. A rough estimate on MPs retention in the pond indicated that MPs were retained at efficiencies similar to that of other particulate materials occurring in the stormwater runoff.

Published: July 2019

Agricultural drainage plays an effective role in preventing waterlogging and salinity disasters and also is the main transport pathway for agricultural non-point source pollutants into rivers and lakes. Hence, the water quality of agricultural drainage should be a point of focus. In this paper, nitrogen and phosphorus loss under improved subsurface drainage with different filter materials (gravel, layered sand-gravel, mixed sand-gravel, straw) were studied by a three-year field experiment (2016–2018) compared with the conventional subsurface drainage. The pH values, total nitrogen, ammonia nitrogen, nitrate nitrogen, total phosphorus and soluble reactive phosphate were considered. The results showed that the nitrogen and phosphorus concentrations of drain outflow under improved subsurface drainage with gravel filter were larger than that with layered sand-gravel filter and mixed sand-gravel filter. The improved subsurface drainages with layered sand-gravel filter and mixed sand-gravel filter had an effect on reducing the ammonia nitrogen, total phosphorus and soluble reactive phosphate concentrations of the outflow. Meanwhile, the characteristics of nitrogen and phosphorus loss under the improved subsurface drainage with straw filter were different from that with layered sand-gravel filter and mixed sand-gravel filter. For the improved subsurface drainage with layered sand-gravel filter outflow, the ammonia nitrogen, total phosphorus, and soluble reactive phosphate concentrations were about 13%–78%, 38%–63%, 40%–68% less, and total nitrogen, nitrate nitrogen concentrations were 24%–80%,18%–96% more than that under conventional subsurface drainage. Meanwhile, for the improved subsurface drainage with straw filter outflow, compared with conventional subsurface drainage outflow, the percentage changes of the total nitrogen, nitrate nitrogen, ammonia nitrogen, total phosphorus and the soluble reactive phosphate concentrations were about −76%–62%, −77%–78%, −152%–−274%, −103%–−400% and −221%–−291%, respectively. Additionally, in the outflow of all subsurface drainage patterns, there were much higher total nitrogen and nitrate nitrogen concentrations which should be focused on and the agricultural water management should be adopted.
Monitoring Coastal Lagoon Water Quality through Remote Sensing: The Mar Menor as a Case Study
Authors: Erena Manuel , Domínguez José , Aguado-Giménez Felipe , Soria Juan , García-Galiano Sandra
Published: July 2019

The Mar Menor is a hypersaline coastal lagoon located in the southeast of Spain. This fragile ecosystem is suffering several human pressures, such as nutrient and sediment inputs from agriculture and other activities and decreases in salinity. Therefore, the development of an operational system to monitor its evolution is crucial to know the cause-effect relationships and preserve the natural system. The evolution and variability of the turbidity and chlorophyll-a levels in the Mar Menor water body were studied here through the joint use of remote sensing techniques and in situ data. The research was undertaken using Operational Land Imager (OLI) images on Landsat 8 and two SPOT images, because cloudy weather prevented the use of OLI images alone. This provided the information needed to perform a time series analysis of the lagoon. We also analyzed the processes that occur in the salt lagoon, characterizing the different spatio-temporal patterns of biophysical parameters. Special attention was given to the role of turbidity and chlorophyll-a levels in the Mar Menor ecosystem with regard to the programs of integral management of this natural space that receives maximum environmental protection. The objective of the work has been fulfilled by answering the questions of the managers: when did the water quality in the Mar Menor begin to change? What is happening in the lagoon? Is remote sensing useful for monitoring the water quality in the Mar Menor? The answers to these questions have allowed the generation of a methodology and monitoring system to track the water quality in the Mar Menor in real-time and space. The tracking system using satellite images is open to the incorporation of images provided by new multispectral sensors.
Provision and accessibility of primary healthcare services for people who are homeless: a qualitative study of patient perspectives in the UK
Authors: Gunner Ellie , Chandan Sat Kartar , Marwick Sarah , Saunders Karen , Burwood Sarah , Yahyouche Asma , Paudyal Vibhu
Published: July 2019

Background

Anecdotal reports of people who are homeless being denied access and facing negative experiences of primary health care have often emerged. However, there is a dearth of research exploring this population’s views and experiences of such services.

Aim

To explore the perspectives of individuals who are homeless on the provision and accessibility of primary healthcare services.

Design and setting

A qualitative study with individuals who are homeless recruited from three homeless shelters and a specialist primary healthcare centre for the homeless in the West Midlands, England.

Method

Semi-structured interviews were audiorecorded, transcribed verbatim, and analysed using a thematic framework approach. The Theoretical Domains Framework (TDF) was used to map the identified barriers in framework analysis.

Results

A total of 22 people who were homeless were recruited. Although some participants described facing no barriers, accounts of being denied registration at general practices and being discharged from hospital onto the streets with no access or referral to primary care providers were described. Services offering support to those with substance misuse issues and mental health problems were deemed to be excluding those with the greatest need. A participant described committing crimes with the intention of going to prison to access health care. High satisfaction was expressed by participants about their experiences at the specialist primary healthcare centre for people who are homeless (SPHCPH).

Conclusion

Participants perceived inequality in access, and mostly faced negative experiences, in their use of mainstream services. Changes are imperative to facilitate access to primary health care, improve patient experiences of mainstream services, and to share best practices identified by participants at the SPHCPH.
Prevalence, characteristics, and patterns of patients with multimorbidity in primary care: a retrospective cohort analysis in Canada
Authors: Nicholson Kathryn , Terry Amanda L , Fortin Martin , Williamson Tyler , Bauer Michael , Thind Amardeep
Published: July 2019

Background

Multimorbidity is a complex issue in modern medicine and a more nuanced understanding of how this phenomenon occurs over time is needed.

Aim

To determine the prevalence, characteristics, and patterns of patients living with multimorbidity, specifically the unique combinations (unordered patterns) and unique permutations (ordered patterns) of multimorbidity in primary care.

Design and setting

A retrospective cohort analysis of the prospectively collected data from 1990 to 2013 from the Canadian Primary Care Sentinel Surveillance Network electronic medical record database.

Method

Adult primary care patients who were aged ≥18 years at their first recorded encounter were followed over time. A list of 20 chronic condition categories was used to detect multimorbidity. Computational analyses were conducted using the Multimorbidity Cluster Analysis Tool to identify all combinations and permutations.

Results

Multimorbidity, defined as two or more and three or more chronic conditions, was prevalent among adult primary care patients and most of these patients were aged <65 years. Among female patients with two or more chronic conditions, 6075 combinations and 14 891 permutations were detected. Among male patients with three or more chronic conditions, 4296 combinations and 9716 permutations were detected. While specific patterns were identified, combinations and permutations became increasingly rare as the total number of chronic conditions and patient age increased.

Conclusion

This research confirms that multimorbidity is common in primary care and provides empirical evidence that clinical management requires a tailored, patient-centred approach. While the prevalence of multimorbidity was found to increase with increasing patient age, the largest proportion of patients with multimorbidity in this study were aged <65 years.

Authors: Prisco Thiago
Published: July 2019

O presente artigo propõe uma análise sobre um conjunto de saberes, no contexto nacional, acerca do fenômeno da violência contra mulheres praticada no ambiente doméstico e familiar. Adotou-se a pesquisa qualitativa para a análise bibliográfica de produções que envolvem o fenômeno. Concluiu-se que a violência contra a mulher é uma das expressões da violência de gênero, tendo como um dos espaços de “materialização” desse fenômeno o ambiente doméstico e familiar. E que ainda há demanda de maior efetivação de políticas públicas nesse enfrentamento, com intervenções a partir das narrativas de gênero legitimadas no imaginário social brasileiro, para uma cultura de igualdade de direitos, condições sociais dignas e de respeito às mulheres.

A “questão ambiental” é uma das principais expressões contemporâneas da crise do capital. Traz consigo o debate dos rumos do crescimento econômico, desenvolvimento social e preservação do meio ambiente. Dentre os graves problemas ambientais considera-se os resíduos sólidos, que tornaram-se essenciais em virtude dos agravos e impactos que sua má destinação ocasiona ao meio ambiente. Dá-se uma movimentação buscando estratégias de gestão desses resíduos sólidos. A Política Nacional de Resíduos Sólidos é parte constituinte dessa movimentação no Brasil. Neste artigo procura-se mostrar sua construção no bojo da Política Nacional de Meio Ambiente e apontar aspectos problemáticos de sua implantação.

O artigo aborda o trabalho na produção do espaço urbano por meio da compreensão das relações na construção civil no Rio de Janeiro. Estrutura-se em três momentos que trazem o debate da construção e colapso da sociedade do trabalho, tendo como referência o conceito de condição análoga à de escravo no Brasil. Desta forma, apresenta a discussão teórica a respeito dos limites da forma trabalho e da própria conceituação de escravidão hoje, a partir da análise dos relatórios de fiscalização do trabalho escravo na construção civil, de 2013 a 2015, da Superintendência Regional do Trabalho e Emprego no Rio de Janeiro (SRTE/RJ), do Ministério de Trabalho. Números que dão visibilidade à participação dos seres humanos nos escombros do mundo do trabalho.
La Littérature Comparée: Une Voix Qui Se Soulève Dans Le Contexte De La Globalisation
Authors: Barcelos Bettiol Maria Regina
Published: July 2019

A Literatura Comparada ao confrontar diferentes literaturas, disciplinas, em colocar em perspetiva o local e o nacional, tem nos mostrado que a literatura, ainda que em contexto de globalização/mundialização, continua a ser um espaço de resistência, ou seja, o texto literário não é totalmente subserviente aos modelos impostos pela globalização/mundialização, o texto literário tem sempre um olhar crítico e deformador em relação a esses modelos.
A literatura em movimento: desterro na literatura de Herta Müller
Authors: Neumann Gerson , Cunha de Araújo Monique
Published: July 2019

Este artigo debruça-se sobre a escrita da autora romeno-alemã Herta Müller, particularmente na temática do desterro. O termo sinônimo para exílio relaciona-se diretamente com os dias atuais, quando milhares de pessoas são obrigadas a se deslocar de seus territórios de origem para outros, onde procuram, sobretudo, segurança. Explorar a obra de Herta Müller não se trata somente de verificar sua escrita a partir de teorias específicas, como as propostas por Ette, Said, Arendt e Greverus, significa, antes de tudo, investigar uma escrita de resistência, em que o uso da língua é o principal instrumento de combate.
“EU SOU NO NORTE, HOJE CANTO A MINHA SORTE*”: OS FLUXOS, MOVIMENTOS E SOCIABILIDADES JUVENIS NA QUADRILHA JUNINA EM SOBRAL/CE
Authors: Castro Thiago Silva de , Oliveira Wenderson Silva
Published: July 2019

Com olhos voltados aos fluxos culturais das/nas quadrilhas juninas em Sobral/CE, espaço de aprendizagens não formalizados e complementares à escola, este artigo procura discutir os processos de socialização da juventude participante do movimento quadrilheiro. Amparados pela literatura que pesquisa com/nos cotidianos, tentamos captar as mais fugazes situações de sociabilidades e como lócus para nossa observação e conversas, acompanhamos os encontros-partilhas na/da Quadrilha Estrela do Luar, na mesma cidade citada acima. Nosso objetivo é, portanto, tentar estruturar e descrever uma identidade específica, não estanque, aquela que se refere à juventude quadrilheira de um modo geral.
EDUCAÇÃO FINANCEIRA NAS ESCOLAS: UMA DISCUSSÃO FEITA A PARTIR DE EXPERIÊNCIAS VIVENCIADAS PELO PROGRAMA DE EDUCAÇÃO FINANCEIRA NAS ESCOLAS – ENSINO MÉDIO

Published: July 2019

No Brasil, a discussão sobre educação financeira foi impulsionada pela Estratégia Nacional de Educação Financeira, que propôs o Programa de Educação Financeira nas Escolas – Ensino Médio. Em Pernambuco, implantou-se educação financeira em 89 escolas públicas de Ensino Médio em 2015. Neste artigo, apresentamos a análise de rodas de conversas com professores e alunos de duas escolas. Alunos e professores consideraram válida a proposta de educação financeira a partir do material sugerido para as escolas. Destacaram a estreita relação entre educação financeira e Matemática, ressaltando o uso de conhecimentos matemáticos para a realização das atividades propostas. Apontaram ainda para a necessidade de formação do professor para atuar com educação financeira nas escolas.
O USO DA ESTIMATIVA EM TAREFAS NUMÉRICAS COM ALUNOS DO 3º ANO DO ENSINO FUNDAMENTAL NA PERSPECTIVA DO SENTIDO DE NÚMERO
Authors: Sander Giovana Pereira , Pirola Nelson Antônio , Brocardo Joana
Published: July 2019

A estimativa é um aspecto de sentido de número utilizado na resolução de tarefas numéricas em que se busca a relação entre o contexto do problema e o cálculo necessário para resolvê-lo, considerando valores exatos e globais. O objetivo da pesquisa foi investigar se os alunos do 3º ano do Ensino Fundamental realizavam cálculo por estimativa e de que modo realizavam ao resolverem tarefas numéricas. Participaram da investigação 351 alunos de 12 escolas públicas de uma cidade do interior do Estado de São Paulo. Foram utilizadas duas tarefas numéricas que poderiam ser resolvidas por meio de estimativa. A análise dos dados mostrou que a estimativa foi pouco utilizada, predominando o uso de algoritmos, o que prejudica o desenvolvimento do sentido de número e do cálculo mental.

EDUCAÇÃO FINANCEIRA NOS ANOS INICIAIS DO ENSINO FUNDAMENTAL: UM OLHAR PARA A FORMAÇÃO DOCENTE
Authors: Oliveira Anaelize dos Anjos , Pessoa Cristiane Azevêdo dos Santos
Published: July 2019

O presente artigo, tratando-se do recorte de um estudo maior, propõe-se a analisar o processo de formação continuada acerca da Educação Financeira (EF) ofertada aos professores dos anos iniciais do Ensino Fundamental. O método consistiu em entrevistas semiestruturadas com duas professoras que participaram da formação. Os resultados evidenciam limitações no processo de formação continuada, baseando-se apenas na discussão de orçamentos e na apresentação de livros didáticos e paradidáticos de EF. A ênfase do trabalho girou em torno do ensino de conhecimentos econômico-financeiros com orientações sobre como obter, usar e poupar dinheiro. Ressaltamos a necessidade de ampliação das discussões referentes à EF no âmbito dos processos de formação de professores, não restringindo o processo a finanças pessoais, muito menos direcionando a prática docente ao ensino de como os alunos devem agir.
La lasergrammétrie aéroportée, approches théoriques, concepts, méthodes
Authors: Vallet Julien
Published: July 2019

Depuis une dizaine d'années, la lasergrammétrie ou LiDAR aéroporté est une technique reconnue et quasi classique pour détermi¬ ner la topographie de notre environnement. L 'article suivant aborde d 'abord les aspects théoriques de cette technique au travers de ses composants (LiDAR, techniques de balayage, technique de géoréférencement direct) et de leurs sources d 'erreurs. Les aspects liés à la performance du système, telles que la précision et la densité des informations, sont présentés. Les grandes quantités de données acquises par cette technique nécessitent un traitement spécifique pour les rendre utilisables. Les phases d 'acquisition et de traitement, du calcul de trajectoire au produit final, sont décrites. Finalement, quelques exemples pratiques de relevés héliportés obliques en terrain montagneux viennent illustrer les capacités de cette technologie.
Quatre années de suivi de la morphodynamique des parois rocheuses du massif du Mont Blanc par laserscanning terrestre

Published: July 2019

L'étude des écroulements rocheux en haute montagne est indispensable pour comprendre l'évolution des paysages et évaluer un risque naturel important. Alors que la vulnérabilité s 'accroît tant en haute altitude que dans les fonds de vallée, la recrudescence actuelle des écroulements dans les Alpes est sans doute à mettre en rapport avec le réchauffement climatique au travers de la dégradation du permafrost de paroi. Toutefois, en raison d 'un manque d'observations systématiques, la fréquence, le volume et les facteurs de déclenchement des écroulements restent mal connus.

Cet article présente et analyse un inventaire de 66 détachements rocheux (là 426 m3) obtenu par comparaison diachronique de modèles 3D à haute résolution issus de campagnes de laserscanning terrestre répétées annuellement entre 2005 et 2009 sur 9 parois rocheuses du massif du Mont Blanc. Ces parois sont situées entre 3000 et 4500 m d'altitude. Elles présentent une grande diversité de pente, d 'orientation et de densité de fracturation, et ont connu des évolutions très variés. Le paramètre permafrost semble expliquer la plupart de ces évolutions.
