Published: November 2018

O aproveitamento da semente de açaí em bebida à base de café é uma alternativa para a redução do impacto ambiental e para a agregação de valor ao resíduo da agroindústria de açaí. Objetivou–se com a condução do presente trabalho avaliar o aproveitamento da semente de açaí, subproduto do beneficiamento dos frutos, para a produção de uma bebida
à base de café e semente de açaí. Foram feitas a torrefação e moagem da semente de açaí e de grãos de café, tendo sido analisada sensorialmente a bebida nas concentrações (0, 25, 50, 75 e 100%) de semente de açaí, foram feitas ainda análises de polifenóis da amostra da bebida de maior aceitação sensorial e das amostras controles (0 e 100% de semente de açaí) e de minerais da amostra da bebida de maior aceitação sensorial e das amostras controles. A análise sensorial mostrou que a amostra contendo 25% de sementes de açaí foi a de maior aceitação, mas apresentou baixos teores de polifenóis totais quando comparada com a bebida 100% café. Alguns minerais não diferiram estatisticamente
em nível de 1% de probabilidade. A adição de sementes de açaí, em baixas concentrações, na bebida à base de café
mostrou ser uma alternativa viável para aproveitamento desse resíduo.

Published: November 2018

Dentre os sistemas de irrigação existentes, o pivô central merece destaque por ocupar grandes áreas e consumir um grande
volume de água. Diante disso, a utilização de equipamentos mais eficientes é uma busca constante, havendo necessidade
de melhoria das metodologias existentes para sua avaliação. A presente pesquisa busca propor uma nova metodologia para
determinar a uniformidade de distribuição de água por pivôs centrais. Foram utilizadas áreas irrigadas de 40, 60, 80, 100 e
120 ha, e em cada uma delas, avaliados dez pivôs centrais. Os tratamentos foram compostos de: pluviômetros equidistantes
com o coeficiente de uniformidade de Christiansen (CUC) calculado conforme Christiansen (1942), modificado por
Heermann e Hein (1968) (Método 1); pluviômetros instalados de forma que cada um representasse uma área amostral de
0,5 ha com o CUC calculado conforme Christiansen (1942) (Método 2); e (Métodos 3, 4, 5, 6 e 7): idem método 2, porém
com coletores instalados, de forma que cada um representasse área amostral de 1, 2, 3, 4 e 5 ha, respectivamente. Obteve-se
a área adequadamente irrigada (AAI) para obtenção do coeficiente de regressão da reta para cada avaliação. A determinação
da uniformidade de pivôs centrais pelo método 2 foi a metodologia que mais se relacionou com o conceito de AAI, seguida
das metodologias 1 e 3. Para pivôs centrais de tamanhos de 40, 60, 80, 100 e 120 ha, recomendam-se testes de uniformidade
com coletores representando áreas amostrais máximas de até 1,0; 1,1; 1,3; 1,4 e 1,6 ha, respectivamente.

Authors: Matos Mateus Pimentel de , Matos Antonio Teixeira de 
Published: November 2018

O lodo de esgoto doméstico, após ter sido higienizado com a adição de cal, pode ter aproveitamento agrícola efetuado como corretivo de acidez e de fertilidade. Entretanto, pouco se conhece das características do lodo de esgoto após ter sido submetido à caleação. Por esta razão, objetivou-se, com a realização deste trabalho, definir as doses de cal para higienização de um lodo gerado no tratamento primário de esgoto doméstico, apresentar suas características químicas, após executada a caleação, além de obter as doses para aplicação em áreas de parques e jardins. O lodo analisado foi coletado no leito de secagem da ETE José Cirilo, Muriaé, MG, e após ser peneirado (malha 2 mm), foi obtida a sua curva de incubação, adicionando-se diferentes doses (0, 25, 50, 100, 150, 200 e 250 kg m-3) de cal hidratada, Ca(OH)2. Para se manter o pH ligeiramente superior a 12, por mais de 2 h após ter sido realizada a mistura, a dose de cal a ser aplicada deve ser de 43,2 kg m-3, e por 72 h deve ser de 71,2 kg m-3. Aplicada a dose de 71,2 kg m-3 no lodo, o material
foi submetido à digestão nítrico-perclórico para quantificação das concentrações totais de N, P, K, Ca, Fe, Na, Mg, Cr, Ni, Cd, Pb, Cu, Mn e Zn. Os valores obtidos, em g kg-1, foram de 10,08 de N; 3,63 de P; 2,80 de K; 3,16 de Ca; e 52,53 de Fe, enquanto que, em mg kg-1, foram de 268,75 de Mg; 33,50 de Ni; 2,25 de Pb; 119,75 de Cu; 499,00 de Mn; e 395,50 de Zn. O Cd e o Cr não foram detectados.

O desenvolvimento da cultura do algodoeiro é diretamente influenciado pela nutrição nitrogenada, a qual é dependente da fertilização mineral. No entanto, o manejo do nitrogênio nesta cultura é complexo, uma vez que doses elevadas também podem provocar efeitos negativos na produtividade da cultura. Nesse contexto, o ajuste fino na dosagem de N fertilizante, de acordo com a demanda da cultura, é essencial para a obtenção de elevadas produtividades. O presente trabalho teve como objetivos: I - estabelecer a curva de resposta de produtividade do algodoeiro ao N fertilizante; II – avaliar a capacidade do sensor óptico em estimar o potencial produtivo. O experimento foi conduzido no ano agrícola de 2012/13 em um Latossolo Vermelho Amarelo, no oeste do estado da Bahia, em três áreas sob clima tropical, com precipitação anual de 1600 mm ano-1 e temperatura média anual em torno de 21 oC. O delineamento experimental foi em blocos ao acaso, com sete tratamentos e três repetições. Os tratamentos consistiram nas seguintes doses de N: 0, 45, 90, 130, 150, 180 e 220 kg ha-1 , aplicadas aos 43 dias após a semeadura (DAS) na área 1 e aos 32 DAS nas áreas 2 e 3. As leituras de IV foram realizadas em três épocas, correspondentes aos 63, 75 e 97 DAS na área 1 e aos 45, 57
e 80 DAS nas áreas 2 e 3, utilizando o sensor óptico N-Sensor LS® (YARA). Adjacente aos estádios e pontos de leitura de IV, foi realizada a determinação de produtividade do algodoeiro. A produtividade da cultura do algodoeiro apresentou um ajuste quadrático com as doses de N nos três experimentos estudados e a dose que atingiu a máxima eficiência econômica foi a de 164, 139 e 167 kg ha-1 de N para as áreas 1, 2 e 3, respectivamente.
Defunct Satellites in Nearly Polar Orbits: Long-term Evolution of Attitude Motion
Authors: Pritykin Dmitry , Efimov Sergey , Sidorenko Vladislav 
Published: November 2018

Abstract
Low Earth orbits (LEO) are known as a region of high space activity and, consequently, space debris highest density. Launcher upper stages and defunct satellites are the largest space debris objects, whose collisions can result in still greater pollution, rendering further space missions in LEO impossible. Thus, space debris remediation is necessary, and the LEO region is a primary target of active debris removal (ADR) projects. However, ADR planning requires at least an approximate idea of the candidate objects’ attitude dynamics, which is one of the incentives for our study. This paper is mainly focused on modeling and simulating the attitude dynamics of defunct satellites. We consider a “boxwing” configuration satellite with an ellipsoid of inertia close to an oblate ellipsoid of revolution. The dynamical model takes into account the gravity-gradient torque, the torque due to the residual magnetic moment, and the torque due to eddy currents induced by the interaction of conductive materials with the geomagnetic field. A better understanding of the intermediate phase of the exponential deceleration and existing final regimes is achieved owing to a more accurate model of the eddy-current torque than in most prior research.We also show the importance of orbital precession, which contributes to the overall attitude motion evolution.

Abstract

Background
Hepcidin concentrations measured by various methods differ considerably, complicating interpretation. Here, a previously identified plasma-based candidate secondary reference material (csRM) was modified into a serum-based two-leveled sRM. We validated its functionality to increase the equivalence between methods for international standardization.

Methods
We applied technical procedures developed by the International Consortium for Harmonization of Clinical Laboratory Results. The sRM, consisting of lyophilized serum with cryolyoprotectant, appeared commutable among nine different measurement procedures using 16 native human serum samples in a first round robin (RR1). Harmonization potential of the sRM was simulated in RR1 and evaluated in practice in RR2 among 11 measurement procedures using three native human plasma samples. Comprehensive purity analysis of a candidate primary RM (cpRM) was performed by state of the art procedures. The sRM was value assigned with an isotope dilution mass spectrometry-based candidate reference method calibrated using the certified pRM.

Results
The inter-assay CV without harmonization was 42.1% and 52.8% in RR1 and RR2, respectively. In RR1, simulation of harmonization with sRM resulted in an inter-assay CV of 11.0%, whereas in RR2 calibration with the material resulted in an inter-assay CV of 19.1%. Both the sRM and pRM passed international homogeneity criteria and showed long-term stability. We assigned values to the low (0.95±0.11 nmol/L) and middle concentration (3.75±0.17 nmol/L) calibrators of the sRM.

Conclusions
Standardization of hepcidin is possible with our sRM, which value is assigned by a pRM. We propose the implementation of this material as an international calibrator for hepcidin.

Abstract
In this article, free vibration of SingleWalled Carbon Nanotube (SWCNT) resting on exponentially varying Winkler elastic foundation is investigated by using Differential Quadrature Method (DQM). Euler-Bernoulli beam theory is considered in conjunction with the nonlocal elasticity theory of Eringen. Step by step procedure is included and MATLAB code has been developed to obtain the numerical results for different scaling parameters as well as for four types of edge conditions. Obtained results are validated with known results in special cases showing good agreement. Further, numerical as well as graphical results are illustrated to show the effects of nonuniform parameter, nonlocal parameter, aspect ratio,Winkler modulus parameter and edge conditions on the frequency parameters.
Pointing and placing: Nominal grounding in Argentine Sign Language
Authors: Martínez Rocío , Wilcox Sherman 
Published: November 2018

AbstractGrounding refers to expressions that establish a connection between the ground and the content evoked by a nominal or finite clause. In this paper we report on two grammatical implementations of nominal grounding in Argentine Sign Language: pointing and placing. For pointing constructions, we also examine distal-proximal pointing and directive force. We introduce the concept of placing, in which a sign is produced at a specific meaningful location in space. Two types of placing are discussed: Placing-for-Creating, in which a new meaningful location is created, and Placing-by-Recruiting, which recruits an existing meaningful location. We suggest that our analysis of pointing and placing provides an account of nominal grounding unified by general cognitive principles as described within the theory of Cognitive Grammar. Pointing is known to occur in all signed languages studied to date. Although previously undocumented, we suggest that placing is also common to many, perhaps all, signed languages.
Disposal and Reinvention: Citizenship in an Era of Electronic Capitalism
Authors: García Canclini Néstor 
Published: November 2018

Abstract
Ever since the expansion of video-politics, television canalises citizens' criticism and demands regarding political authorities, conceiving of citizens as spectators. Social networks magnify this type of involvement, promising horizontality and social cohesion. Political parties have become reduced to elites that distribute power and benefits among themselves, disengaging from voters, except during electoral periods. Our opinions and behaviours are captured by algorithms and subject to globalised forces. The public space where citizenship should be exercised is becoming opaque and distant. Citizenship is radically diminishing while some social movements are reinventing themselves and winning sectorial battles: for human rights, for gender equality, against authoritarianism. Yet the neoliberal approach to technology maintains and deepens greater inequalities. What are the alternatives to this dispossession? Hackers and dissenters? What is the role of the vote in a State-society relationship reprogrammed by technologies and the market?
Electronic health records, communication, and data sharing: challenges and opportunities for improving the diagnostic process

Published: November 2018

Abstract

Background
Diagnosis requires that clinicians communicate and share patient information in an efficient manner. Advances in electronic health records (EHRs) and health information technologies have created both challenges and opportunities for such communication.

Methods
We conducted a multi-method, focused ethnographic study of physicians on general medicine inpatient units in two teaching hospitals. Physician teams were observed during and after morning rounds to understand workflow, data sharing and communication during diagnosis. To validate findings, interviews and focus groups were conducted with physicians. Field notes and interview/focus group transcripts were reviewed and themes identified using content analysis.

Results
Existing communication technologies and EHR-based data sharing processes were perceived as barriers to diagnosis. In particular, reliance on paging systems and lack of face-to-face communication among clinicians created obstacles to sustained thinking and discussion of diagnostic decision-making. Further, the EHR created data overload and data fragmentation, making integration for diagnosis difficult. To improve diagnosis, physicians recommended replacing pagers with two-way communication devices, restructuring the EHR to facilitate access to key information and improving training on EHR systems.

Conclusions
As advances in health information technology evolve, challenges in the way clinicians share information during the diagnostic process will rise. To improve diagnosis, changes to both the technology and the way in which we use it may be necessary.
“The new geography,” material science, and narratology’s space-time dichotomy: Notes toward a geographical narratology
Authors: Easterlin Nancy 
Published: November 2018

AbstractThis essay places narratology’s emphasis on space-time within the emergence of the discipline of geography and the rise of a materialist, hard science orientation in US institutions after WWII, ultimately arguing that a nascent geographical narratology should aspire to the broad intellectual scope of geography’s origins. “The new geography,” which emerged in 1887 and focused comprehensively on the relation of humans to the earth’s surface, subsequently contracted and fragmented with the post-war emphasis on material science. Likewise expanding in the rationalist post-war climate, classical narratology emphasized logical categories, especially the space-time dichotomy, divorced from human meanings. Today, cognitive research suggests that narratology’s enduring space-time paradigm occludes the constructive realities of both human relations to physical locations and reader processes. Drawing on discussions of space in narrative theory and in current cognitive research on navigation, Easterlin demonstrates that readers and viewers, rather than building spatialized storyworlds, construe space in a functional, piecemeal manner. Finally, maintaining that the area ofplace studiesand an ecological approach to reading are two components of a broadly interdisciplinary geographical narratology providing a nuanced, psychologically contextualized approach to human-environment relations and narrative, Easterlin demonstrates their utility in readings of stories by Raymond Carver and Lydia Davis.
Toward a geographical socionarratology
Authors: Hyvärinen Matti 
Published: November 2018

AbstractNarrative space has attracted increasing attention in recent years, yet this attention only sporadically falls on narrative geography. In this article, I consider the possibility of geographical socionarratology and suggest that a geographical approach is able to enrich the perspective of socionarratology. Correspondingly, a social perspective can enhance the interpretative power of geography. Drawing from Jerome Bruner’s (1990, 1991) narrative theory, “canonicity and breach” as well as Reinhart Kosellek’s (2004) theory on the “existential pair” of expectation and experience, I argue that different geographical locations embody different expectations, emotions, and perspectives of action for characters and storytellers. The contradictory play of contested and conflicting expectations is analyzed more closely by reading Ian McEwan’sThe Children Act(2014), a novel portraying competing family cultures and ethical principles. By connecting geography to expectations, I argue, the interpretative advantages of geography in narratology increase substantially.
Mapped stories: Cartography, history, and the representation of time in space
Authors: Carrard Philippe 
Published: November 2018

AbstractAs novels can be mapped, maps in return can be shown to have a narrative dimension. Maps referring to historical events, for instance those of the invasion of the USSR in June 1941, obviously tell a story. Recounted through graphic means, that story has specific aspects in the areas of order, duration, frequency, authorship, and perspective. Yet, similar in this respect to the descriptions that historians provide, narrative maps are neither neutral, nor whole. Grounded in selection, they necessarily develop an argument, are incomplete, and rely on symbols that are both conventional and arbitrary.
Affording innerscapes: Dreams, introspective imagery and the narrative exploration of personal geographies
Authors: Bernini Marco 
Published: November 2018

AbstractThe essay presents an interdisciplinary theory of what it will call “innerscapes”: artefactual representations of the mind as a spatially extended world. By bringing examples of innerscapes from literature (Kafka’s short storyThe Bridge), radio plays (Samuel Beckett’sEmbers), and a creative documentary about auditory-verbal hallucinations (a voice-hearer’s short film,Adam + 1), it suggests that these spatial renditions of the mind are constructed by transforming the quasi-perceptual elements of inner experience into affording ecologies. In so doing, they enable an enactive exploration of inner worlds as navigable environments. The resulting storyworlds display features that resemble the logic and ontology of dreams. Cognitive research on dreams and cartographical studies of the personal geographies of dreamscapes will thus inform the understanding of what innerscapes are, do and can do if used, as the essay argues they should be, as enhancing devices for what Jesse Butler has called ‘extended introspection” (2013: 95).
The middle, the east, the west of Erin: Narrative disorientation and the production of space
Authors: McAllister Brian J. 
Published: November 2018

AbstractThis essay extends political and aesthetic implications in relationships between space and narrative by investigating narrative strategies that displace or disrupt access to narrative setting, spatiotemporal movement, or the space of narration. I fuse Henri Lefebvre’s work on the social production of space to Gabriel Zoran’s systems of narrative space in order to propose a spatial critique that describes and categorizes ways that narrative is central to the politics of spatial practice. I then apply that spatial critique to Flann O’Brien’s prototypically disorienting novelAt Swim-Two-Birds(1939). In that intersection between critical geography and narrative theory,At Swim-Two-Birdsbecomes a narrative about the complicated interplay between creation and control of space – the way that space is configured and reconfigured through spatial practice.
Narrative space in Ian McEwan’sSaturday: A narratological perspective
Authors: Koron Alenka 
Published: November 2018

AbstractAlthough the work of Ian McEwan, one of the most important modern British writers, has been quite thoroughly researched, the narrative space was rarely the subject of narratological treatment. This article tackles a close reading of McEwan’s novelSaturdayfrom a narratological perspective testing the applicability of a series of spatial categories systematized by Marie-Laure Ryan in the already existing narratological tradition and in her own research in narrative space. At the macro level of the story, the circular structure of the novel and the concepts of space as a container and space as a network are being shown and so is the use of local names. In the foreground there is a discussion of the five fundamental levels of narrative space (spatial frames, setting, story space and spaces of intertextuality, storyworld, narrative universe), followed by the treatment of textualization at the micro level (perspectivism and aperspectivism, map, and tour, and the lived experience of space). The analysis of space representation inSaturdayeventually makes it possible to conclude that McEwan promotes the conception of space that became prominent within the spatial turn in postmodern humanities.
