Analysis of amorphous regions in severely marformed NiTi shape memory alloy
Authors: Świec Paweł , Zubko Maciej , Stróż Danuta , Lekston Zdzisław
Published: May 2018

In this work Ni-rich NiTi alloy subjected to 35 % cold-rolling in the martensitic state followed by annealing at 450 °C for 15 min has been studied by transmission electron microscopy observations. It has been found that the material after thermo-mechanical treatment has a non-uniform nanostructure with canal-like shaped amorphous areas containing crystallites of R and B19′ phases. Zones surrounding these regions contain grains elongated in different directions in different areas. They are identified to be a mixture of B2 parent, R rhombohedral and B19′ martensitic phases. Selected area electron diffraction as well as transmission electron microscope orientation maps taken from these zones exhibit differences in their crystallographic orientations. It is proposed that the amorphous areas form along grain boundaries during severe plastic deformation.
Binary diffusion behaviour in Ti–X (X = Al, Mo, V, Cr, Fe) alloys
Authors: Chen Yi , Cheng Liang , Tang Bin
Published: May 2018

Interdiffusion coefficients of the β single-phase in the Ti-rich portion of the binary Ti–X (X = Al, Mo, V, Cr, Fe) systems at 1 523 K were determined by annealing infinite diffusion couples between appropriate pairs of alloys. The values were derived from the concentration profiles by electron probe microanalysis coupled with the Boltzmann–Matano method. The comparison of the interdiffusion coefficients in these binary Ti–X (X = Al, Mo, V, Cr, Fe) systems show that the Mo diffuses the least while the Fe diffuses fastest in titanium alloys. Furthermore, the values of the interdiffusion coefficients of the Ti–Al, Ti–V and Ti–Cr binary systems were similar.
Two-Step Sintering of Alumina/Zirconia Functionally Graded Materials
Authors: Arantes V. L. , Neto A. L. P. , Silveira S.
Published: May 2018

The interest for functionally graded materials (FGM) has grown up during the last 2 decades owing to the possibility of developing pieces and devices with gradual variation of properties along one or more dimensions. This allows for an optimum performance as a function of the intended use. On the other hand, two stage sintering is a relative new sintering technique, where the shaped pieces are heated up to a relative density of 75–92 % of theoretical density, followed by a fast cooling step to an inferior temperature, where the piece in maintained up to the end of the densification process. This results in the development of finer microstructures, responsible for better mechanical properties. In this work, we characterized alumina-ytria-stabilized zirconia composites, with different amounts of 3Y-ZrO2 by dilatometry. After fitting thermal behavior of the different composites during sintering and determining temperature of maximum densification rate, co-pressed FGMs were produced. Then the samples were sintered by pressureless traditional technique and two stage sintering, with a peak temperature of 1450 °C and holding temperature of 1350 °C. Microstructure was studied by SEM and mechanical properties (microhardness and indentation toughness) were determined in order to compare pressureless sintered FGMs at 1500 °C and two-stage sintered FGMs.
Congestion from a Multimodal Perspective
Authors: Rudolph Frederic , Mátrai Tamás
Published: May 2018

This paper investigates the multimodal nature of urban congestion and network performance, with the aim of developing practice ready policy tools to alleviate the adverse effects of excess demand, no matter in which mode it realizes. As part of the efforts to get an overall understanding of how congestion is defined in various disciplines, we conduct a literature review of relevant engineering and microeconomics studies. The investigation reveals the main areas where contradiction can be identified between engineering and economics approaches. In a second step, we investigate the results of an expert survey about the principles of congestion analysis from a multimodal perspective. The main contribution of the paper is twofold. First, we draw attention to the pitfalls of oversimplified and narrow viewpoints on congestion. Second, we operationalize these principles in order to enable decision makers to assess the impact of urban transport measures on congestion.
Reading Now and Again: Hyperarchivalism and Democracy in Ranjan Ghosh and J. Hillis Miller's Thinking Literature across Continents
Authors: Fest Bradley J.
Published: May 2018

This review essay approaches Ranjan Ghosh and J. Hillis Miller's Thinking Literature across Continents (2016) from a set of questions about what it means to read in the age of hyperarchival accumulation. Written against the background of events in the United States and elsewhere during the fall of 2017, the essay tracks and assesses Ghosh and Miller's differing methods for approaching literary study in the twenty-first century: undiscriminating catholicity and rhetorical reading, respectively. Through emblematic readings of David Foster Wallace's novel The Pale King ( 2011 ), the videogame Katamari Damacy ( 2004 ), and Amy Hungerford's Making Literature Now ( 2016 ), this essay argues that Thinking Literature across Continents self-reflexively models and performs the interested, situated reading practices necessary for continuing the never-ending project of encountering, sharing, accounting for, learning from, and contending with others and their divergent readings, practices that, though many may have lost sight of them today, are fundamental to the project of democracy itself.
Quantification of the Central Cardiovascular Network Applying the Normalized Short-time Partial Directed Coherence Approach in Healthy Subjects
Authors: Schulz Steffen , Bolz Mathias , Bär Karl-Jürgen , Voss Andreas
Published: May 2018

Background: The central control of the autonomic nervous system (ANS) and the complex interplay of its components can be described by a functional integrated mode – the central autonomic network (CAN). CAN represents the integrated functioning and interaction between the central nervous system (CNS) and ANS (parasympathetic and sympathetic activity).

Objective: This study investigates the central cardiovascular network (CCVN) as a part of the CAN, during which heart rate (HR), systolic blood pressure (SYS) and frontal EEG activity in 21 healthy subjects (CON) will be analysed. The objective of this study is to determine how these couplings (central-cardiovascular) are composed by the different regulatory aspects of the CNS-ANS interaction.

Methods: To quantify the short-term instantaneous causal couplings within the CCVN, the normalized short time partial directed coherence (NSTPDC) approach was applied. It is based on an m-dimensional MAR process to determine Granger causality in the frequency domain.

Results: We found that CCVN were of bidirectional character, and that the causal influences of central activity towards HR were stronger than those towards systolic blood pressure. This suggests that the central-cardiac closed-loop regulation process in CON focuses mainly on adapting the heart rate via the sinoatrial node rather than focusing on SYS. The CNS-ANS coupling directions with respect to central spectral power bands were characterized as mostly bidirectional, where HR and SYS acted as drivers in nearly every frequency band (unidirectional for α, α1 and α2).

Conclusion: This study provides a more indepth understanding of the interplay of neuronal and autonomic cardiovascular regulatory processes in healthy subjects, as well as a greater insight into the complex CAN.
Application of Empirical Mode Decomposition to Mother and Infant Physical Activity
Authors: Shimizu Etsuko , Kim Jinhyuk , Yoshiuchi Kazuhiro , Yamamoto Yoshiharu , Nakamura Toru
Published: May 2018

Background: The mutual dependencies between mother and infant circadian rhythms are important for examining disturbances of maternal circadian rhythms, which are considered substantial risk factors for the development of maternal depression during childrearing periods.

Objectives: We characterized the mutual dependencies of maternal–infant circadian rhythms by an index of synchronization properties and then tested the hypothesis that such an index, specifically the instantaneous phase differences between their rhythms, is associated with maternal mental health.

Methods: We performed longitudinal recordings of maternal symptoms of fatigue, stress, and mood states by ecological momentary assessment, together with simultaneous measurements of mother and infant physical activity data in daily life, on 20 mother–infant pairs for a period of >1 week. The circadian components in their physical activity data were extracted by ensembled bivariate empirical mode decomposition, and the corresponding instantaneous phases were then obtained based on the Hilbert transformation. The associations between diurnal maternal symptoms and absolute phase differences between mother and infant circadian rhythms were tested by multilevel models.

Results: Diurnal fatigue and depressive mood scores showed positive and significant correlations (p < 0.05) with the increase in instantaneous mother–infant phase differences, indicating the significant role of synchronization of mother–infant circadian rhythms for maintaining maternal mental health.

Conclusions: These findings suggest that modifications of maternal and/or infant circadian rhythms may lead to the improvement of maternal mental health during child-rearing periods.
Correlation effects and many-body interactions in water clusters
Authors: Heßelmann Andreas
Published: May 2018

Background: The quantum-chemical description of the interactions in water clusters is an essential basis for deriving accurate and physically sound models of the interaction potential for water to be used in molecular simulations. In particular, the role of many-body interactions beyond the two-body interactions, which are often not explicitly taken into account by empirical force fields, can be accurately described by quantum chemistry methods on an adequate level, e.g., random-phase approximation electron correlation methods. The relative magnitudes of the different interaction energy contributions obtained by accurate ab initio calculations can therefore provide useful insights that can be exploited to develop enhanced force field methods.

Results: In line with earlier theoretical studies of the interactions in water clusters, it has been found that the main contribution to the many-body interactions in clusters with a size of up to N = 13 molecules are higher-order polarisation interaction terms. Compared to this, many-body dispersion interactions are practically negligible for all studied sytems. The two-body dispersion interaction, however, plays a significant role in the formation of the structures of the water clusters and their stability, since it leads to a distinct compression of the cluster sizes compared to the structures optimized on an uncorrelated level. Overall, the many-body interactions amount to about 13% of the total interaction energy, irrespective of the cluster size. The electron correlation contribution to these, however, amounts to only about 30% to the total many-body interactions for the largest clusters studied and is repulsive for all structures considered in this work.

Conclusion: While this shows that three- and higher-body interactions can not be neglected in the description of water complexes, the electron correlation contributions to these are much smaller in comparison to the two-body electron correlation effects. Efficient quantum chemistry approaches for describing intermolecular interactions between water molecules may therefore describe higher-body interactions on an uncorrelated Hartree–Fock level without a serious loss in accuracy.

Authors: Treiber Linda A. , Jones Jackie H.
Published: May 2018

Background:

The purpose of this study was to better understand individual- and system-level factors surrounding making a medication error from the perspective of recent Bachelor of Science in Nursing graduates.

Method:

Online survey mixed-methods items included perceptions of adequacy of preparatory nursing education, contributory variables, emotional responses, and treatment by employer following the error.

Results:

Of the 168 respondents, 55% had made a medication error. Errors resulted from inexperience, rushing, technology, staffing, and patient acuity. Twenty-four percent did not report their errors. Key themes for improving education included more practice in varied clinical areas, intensive pharmacological preparation, practical instruction in functioning within the health care environment, and coping after making medication errors.

Conclusion:

Errors generally caused emotional distress in the error maker. Overall, perceived treatment after the error reflected supportive environments, where nurses were generally treated with respect, fair treatment, and understanding. Opportunities for nursing education include second victim awareness and reinforcing professional practice standards. [

Authors: Fesakis Georgios , Karta Pascalina , Kozas Kontantinos
Published: May 2018

Seeking a systematic combination of the pedagogical model of m-learning with the Realistic Mathematics Education (RME) approach, this study concerns the use of math trail as a learning activity model that can take the advantages of mobile computing devices for the design of effective learning experiences in an authentic context. The paper presents the design and the case study of the first pilot implementation of a math trail, using mobile devices for primary school students. In this math trail, the students are guided, through a digital map, to a sequence of preselected sites of a park where they solve specially designed math problems using data from the environmental context. The students measure real objects’ dimensions either with conventional instruments or by measurement applications of their tablet. According to the findings of the study, students solved the puzzles by applying mathematical knowledge, discussion and collaboration. The students applied and reinforced their knowledge through an effective and engaging learning activity. Moreover, the students were puzzled about the differences of the measurements by conventional and digital instruments and this confusion triggered social negotiation. Further research is needed for a grounded theory development about m-learning design for RME.

Examples of the developed training courses for the engineering disciplines are presented. Examples include the use of the proposed approach for "Machine Parts" and "Theory of Machines and Mechanisms" technical training courses in terms of practice-based learning. Problems of application of various systems of e-learning and technologies of development of the courses for e-learning are discussed.
Cutting Edge: The Histone Methyltransferase G9a Is Required for Silencing of Helper T Lineage–Associated Genes in Proliferating CD8 T Cells

Helper versus cytotoxic T lineage decision in the thymus has been studied as a model for silencing of alternative lineage genes. Although the transcription factor RUNX3 is required for the initiation of Cd4 silencing in developing CD8 T cells, it is unknown how silencing of Cd4 and other helper T lineage genes is maintained. We show that the histone methyltransferase G9a is necessary for silencing helper T lineage genes in proliferating mouse CD8 T cells. Despite normal initial Cd4 downregulation, G9a-deficient CD8 T cells derepress Cd4 and other helper lineage genes during repeated division in lymphopenia or in response to tumor Ag. However, G9a was dispensable for continued silencing of those genes in CD8 T cells that respond to infection by Listeria monocytogenes. These results demonstrate that G9a facilitates maintenance of cellular identity of CD8 T cells during cell division, which is further reinforced by inflammatory signals.
La trama en la Ciudad Artesanal de Sèvres: síntesis de las aspiraciones de una generación.
Authors: Martín Domínguez Guiomar , De Esteban Garbayo Javier
Published: May 2018

Aunque solían firmar los proyectos bajo un nombre común, los tres miembros del equipo Candilis-Josic-Woods también desarrollaron trabajos de forma independiente. Así sucede en la Ciudad Artesanal de Sèvres realizada por Alexis Josic entre 1961 y 1965. Concebida tan solo un año antes que la Universidad Libre de Berlín, en paralelo al concurso para la reconstrucción de Frankfurt y mientras Woods publicaba en Le Carré Bleu su teoría sobre el concepto de “web”, esta propuesta supuso un avance decisivo en el uso de patrones geométricos de repetición como método de proyecto por parte del equipo, y permitió fijar algunos temas característicos de trabajos posteriores, todo ello, desde una manifiesta sencillez formal. La definición de un sistema de proyecto abierto y evolutivo, la búsqueda de una renovada identidad espacial alternativa a los cánones del estilo internacional o la reinterpretación del esqueleto arquitectónico desde sus posibilidades de negociación creativa con el usuario fundamentan una “idea de trama”, que también supone la síntesis de muchas de las aspiraciones del Team X. El objetivo de este artículo no es otro que contribuir a una mejor comprensión de las connotaciones estéticas, culturales y sociales que los mecanismos de crecimiento modular adquirieron en ese particular contexto de la revisión moderna.

Published: May 2018

Hackney Marshes es una gran área de pastizales en el este de Londres, una zona adyacente al Parque Olímpico. Siendo en origen un pantano, fue drenado en la época medieval y utilizado para la recreación y el deporte desde el siglo XVIII. Más tarde fue cubierto con escombros de edificios dañados durante la Segunda Guerra Mundial. Hoy en día, el lugar es conocido por su extensión, a través de la cual existen campos de fútbol, rugby y cricket, siendo considerado el hogar del fútbol de la Liga Dominical.
Central Saint Martins, London.
Authors: Architects Stanton Willimas
Published: May 2018

Central Saint Martins es una institución líder en la educación de arte y diseño, con raíces en el movimiento Arts and Crafts de finales del siglo XIX. El nuevo edificio reúne, por primera vez, en una entidad cohesiva, distintas disciplinas que anteriormente estaban ubicadas en diferentes partes del centro de Londres.

El proyecto para el nuevo campus de Central Saint Martins fue la clave para la regeneración de King's Cross. El proyecto inició la transformación del que fue uno de los principales centros de transporte del Londres Victoriano, un área que estaba en estado casi delictivo. La reurbanización de esta parte de la ciudad es uno de los proyectos de regeneración urbana más grandes y ambiciosos de Europa.

Simon Sainsbury Centre, Cambridge Judge Business School.
Authors: Architects Stanton Willimas
Published: May 2018

El Simon Sainsbury Centre es una extensión del Cambridge Judge Business School, perteneciente a la Universidad de Cambridge en Inglaterra. El proyecto se origina a partir de un plan director para complementar y actualizar un escenario arquitectónico complejo, creado por la yuxtaposición y combinación de edificios e intervenciones arquitectónicas de diferentes períodos, algunos de los cuales tienen un carácter arquitectónico particular.

El sitio fue originalmente ocupado por el Hospital Addenbrooke, cuyas estructuras principales han sufrido varias transformaciones desde su construcción. Los cambios más notables del edificio han sido, en primer lugar, la adaptación de su fachada en la década de 1860, ejemplo del característico resurgimiento ecléctico victoriano de Matthew Digby Wyatt, y, en segundo lugar, la ampliación para alojar el Cambridge Judge Business School en la década de 1990, a partir de un estilo inglés postmoderno y extravagante propio de John Outram. 
Occupational Therapy Interventions Supporting Social Participation and Leisure Engagement for Community-Dwelling Older Adults: A Systematic Review
Authors: Smallfield Stacy , Molitor Whitney Lucas
Published: May 2018

This systematic review examines the evidence for the effectiveness of interventions within the scope of occupational therapy that address leisure engagement and social participation among community-dwelling older adults. Eleven Level I, 1 Level II, 1 Level III, and 1 Level IV studies met inclusion criteria. Included articles addressed two themes: interventions supporting social participation and interventions supporting leisure engagement. Strong evidence supports leisure education interventions to enhance leisure engagement, and moderate evidence supports chronic disease self-management programs to support leisure engagement. Mixed evidence exists for community-based group interventions and electronic gaming to support social participation. Routine use of leisure education and chronic disease self-management programs to enhance leisure engagement and selective use of community-based groups and electronic gaming to support social participation are recommended.

Published: May 2018

OBJECTIVE. We investigated associations among activity engagement (AE), number of available and relevant everyday technologies, ability to use everyday technologies, and cognitive status among older adults in an urban area.

METHOD. This cross-sectional study included 110 participants and used three assessments: the Frenchay Activities Index to measure AE, the Everyday Technology Use Questionnaire to measure the number of and ability to use available and relevant everyday technologies, and the Montreal Cognitive Assessment to measure cognitive status. Data analyses used a one-way analysis of variance and a multiple linear regression model.

RESULTS. The number of available and relevant everyday technologies was significantly different (p < .001) among groups that varied in level of AE. Ability to use everyday technologies did not significantly differ among groups. Cognitive status did not explain level of AE when the number of available and relevant everyday technologies was considered.

CONCLUSION. Increasing the accessibility of available and relevant everyday technologies among older adults in an urban area may increase AE.

Published: May 2018

Se hace una aproximación al posible vínculo entre los incendios forestales y los cultivos ilícitos, para ello se revisan datos y estadísticas sobre los incendios forestales y las áreas geográficas, fechas en que se presentan; se realiza un traslape entre dicha información y la referida a los municipios, donde de acuerdo a información oficial se producen marihuana y amapola; el trabajo se centra en un análisis de los municipios que se localizan en el llamado triángulo dorado. Como conclusión preliminar se puede suponer que se presenta una posible línea de causalidad entre la producción de cultivos ilícitos y los incendios forestales.
Marine biogeochemical cycling and climate-carbon cycle feedback simulated by
the NUIST Earth System Model: NESM-2.0.1
Authors: Dai Yifei , Cao Long , Wang Bin
Published: May 2018

Abstract. In this study, we evaluate the performance of Nanjing University of Information Science & Technology Earth System Model, version 2.0.1 (hereafter NESM-2.0.1). We focus on model simulated historical and future oceanic CO2 uptake, and analyze the effect of global warming on model-simulated oceanic CO2 uptake. Compared with available observations and data-based estimates, NESM-2.0.1 reproduces reasonably well large-scale ocean carbon-related fields, including nutrients (phosphate, nitrite and silicate), chlorophyll, and net primary production. However, some noticeable discrepancies between model simulations and observations are found in the deep ocean and coastal regions. Model-simulated current-day oceanic CO2 uptake compares well with data-based estimate. From pre-industrial time to 2011, modeled cumulative CO2 uptake is 144 PgC, compared with data-based estimates of 155 ± 30 PgC. Diagnosed from the end of the benchmark 1 % per year CO2 increase simulations, carbon-climate feedback parameter, which represents the sensitivity of ocean CO2 uptake to climate change, is −7.1 PgC/K; Carbon-concentration feedback parameter, which represents the sensitivity of ocean CO2 uptake to increase in atmospheric CO2 is 0.81 PgC/ppm. These two feedback parameters diagnosed from model simulations are consistent with the mean value diagnosed from the CMIP5 (Coupled Model Intercomparison Project phase 5) model simulations under the same 1 % per year CO2 simulations (−7.8 PgC/K and 0.80 PgC/ppm, respectively). Our results demonstrate that NESM-2.0.1 can be used as a useful tool in the investigation of feedback interactions between the ocean carbon cycle, atmospheric CO2, and climate change.

Authors: Wei Y. , Lu M. , Wu W.
Published: May 2018

Abstract. The food security, particularly in Africa, is a challenge to be resolved. The cropland area and spatial distribution obtained from remote sensing imagery are vital information. In this paper, according to cropland area and spatial location, we compare five global cropland datasets including CCI Land Cover, GlobCover, MODIS Collection 5, GlobeLand30 and Unified Cropland in circa 2010 of Africa in terms of cropland area and spatial location. The accuracy of cropland area calculated from five datasets was analyzed compared with statistic data. Based on validation samples, the accuracies of spatial location for the five cropland products were assessed by error matrix. The results show that GlobeLand30 has the best fitness with the statistics, followed by MODIS Collection 5 and Unified Cropland, GlobCover and CCI Land Cover have the lower accuracies. For the accuracy of spatial location of cropland, GlobeLand30 reaches the highest accuracy, followed by Unified Cropland, MODIS Collection 5 and GlobCover, CCI Land Cover has the lowest accuracy. The spatial location accuracy of five datasets in the Csa with suitable farming condition is generally higher than in the Bsk.
