A Two-Stage Fourth-Order Gas-Kinetic Scheme for Compressible Multicomponent Flows
Authors: Pan Liang , Cheng Junxia , Wang Shuanghu , Xu Kun 
Published: July 2017

AbstractWith the use of temporal derivative of flux function, a two-stage temporal discretization has been recently proposed in the design of fourth-order schemes based on the generalized Riemann problem (GRP) [21] and gas-kinetic scheme (GKS) [28]. In this paper, the fourth-order gas-kinetic scheme will be extended to solve the compressible multicomponent flow equations, where the two-stage temporal discretization and fifth-order WENO reconstruction will be used in the construction of the scheme. Based on the simplified two-species BGK model [41], the coupled Euler equations for individual species will be solved. Each component has its individual gas distribution function and the equilibrium states for each component are coupled by the physical requirements of total momentum and energy conservation in particle collisions. The second-order flux function is used to achieve the fourth-order temporal accuracy, and the robustness is as good as the second-order schemes. At the same time, the source terms, such as the gravitational force and the chemical reaction, will be explicitly included in the two-stage temporal discretization through their temporal derivatives. Many numerical tests from the shock-bubble interaction to ZND detonative waves are presented to validate the current approach.
A High-Order Method for Weakly Compressible Flows
Authors: Kaiser Klaus , Schütz Jochen 
Published: July 2017

AbstractIn this work, we introduce an IMEX discontinuous Galerkin solver for the weakly compressible isentropic Euler equations. The splitting needed for the IMEX temporal integration is based on the recently introducedreference solutionsplitting [32, 52], which makes use of theincompressiblesolution. We show that the overall method isasymptotic preserving. Numerical results show the performance of the algorithm which is stable under a convective CFL condition and does not show any order degradation.
Vehicle Routing and Scheduling Problem for a multi-period, multi-perishable product system with time window: A Case study
Authors: Rashidi Komijan Alireza , Delavari Danial 
Published: July 2017

<div data-canvas-width="542.172"><p>The well-known Vehicle Routing Problem (VRP) is to find proper sequence of routes in order to minimize transportation costs. In this paper, a mixed-integer programming model is presented for a food distributer company and the model outputs are to determine the optimal routes and amount of pickup and delivery. In the objective function, the costs of transportation, holding, tardiness and earliness are considered simultaneously. The proposed model with respect to real conditions is multi-period and has two different time periods: one for dispatching vehicles to customers and suppliers and the other for receiving customers’ orders. Time window and split pickup and delivery are considered for perishable products. The proposed model is nonlinear and will be linearized using exact techniques. At the end, model is solved using GAMS and the sensitivity analysis is performed. The results indicate that the trend of changes in holding and transportation costs in compared to tardiness and earliness costs are closed together and are not so sensitive to demand changes.</p></div>

Abstract
OBJECTIVE. We compared performance on a cognitively demanding task, the Weekly Calendar Planning Activity, of participants in three age groups and two countries (United States and Israel).
METHOD. A sample of 375 U.S. and 433 Israeli healthy adults participated. During the activity, participants were observed for speed, accuracy, strategy use, and efficiency.
RESULTS. Accuracy scores were similar in both countries; however, Israeli participants were slower and less efficient (p &lt; .05). The younger and middle-aged Israeli groups were more strategic and the older Israeli group followed fewer rules than the corresponding U.S. groups (p &lt; .05). Older participants in both countries were less accurate, efficient, and strategic than younger participants (p &lt; .05).
CONCLUSION. Limited strategy use and poor time allocation may contribute to difficulty managing cognitively demanding activities for older adults and may also be influenced by culture. Practitioners should consider these factors when screening people for occupational performance difficulties.

AbstractOBJECTIVE. The purpose of this study was to examine the effectiveness of the Family Caregiver Training Program (FCTP) for caregivers of people with dementia.METHOD. A random assignment control group research design with a 3-mo follow-up was implemented.RESULTS. Thirty-six family caregivers of people with dementia demonstrated an increase in activity of daily living (ADL) knowledge (p &lt; .001) and maintenance of that knowledge 3 mo posttest. Caregiver confidence, regardless of group assignment, improved; however, it was not maintained. Burden, depression, and occupational performance and satisfaction remained unchanged for the intervention group; however, physical health as it pertained to quality of life improved 3 mo posttest (p &lt; .001).CONCLUSION. Findings demonstrate that the FCTP can effectively provide knowledge to family caregivers on how to assist people with dementia with ADLs. Even when standard care was provided, there was limited information on ADLs that family caregivers faced daily.

Published: July 2017

AbstractSafety is an issue for older adults with dementia because they are at risk for various incidents. Intelligent assistive technology (IAT) may mitigate risks while promoting independence and reducing the impact on the caregiver of supporting a relative with dementia. The aim of this scoping review was to describe IATs and to identify factors to consider when selecting one. A systematic search was performed of the scientific and gray literature published between 2000 and 2015. A total of 31 sources were included. Four types of IATs were identified as addressing safety issues in dementia: monitoring technologies, tracking and tagging technologies, smart homes, and cognitive orthoses. Characteristics of the device and ethical considerations emerged as key factors to consider when selecting one. IATs yield promising results but pose various challenges, such as adapting to the evolution of dementia. Further research on their actual impact is needed.
Steel
Authors: Fry Tony , Willis Anne-Marie 
Published: July 2017

Steel has, over centuries, played a crucial role in shaping our material, and in particular, urban landscapes. This books undertakes a cultural and ecological history of the material, examining the relationship between steel and design at a micro and macro level – in terms of both what it has been used to design and how it has functioned as a ‘world-making force’, necessary to the development of technologies and ideas.
The research for the book is informed by diverse fields of literature including industry journals, contemporary accounts and technical literature – all framed by rich, early accounts of iron and steel making from the middle ages to the opening of the industrial age, and most notably, the crucial works of Vannoccio Biringuccio, Georgius Agricola, Andrew Ure and Harry Scrivenor.
In contrast, trans-cultural accounts of the history of metallurgy from eminent sinologists and cultural historians like Joseph Neeham and G.E.R. Lloyd are used. Readings on the pre-history and history of science, as well as histories and philosophies technology from scholars such as Siegfried Giedion, Merritt Roe Smith, L.T.C Rolt, Robert B. Gordon inform the analysis. Social and economic history from historians such as Eric Hobsbawn, William T. Hogan and David Brody are consulted; labour process theory is also examined, particularly the influential writings of F.W. Taylor in the late 19th and early 20th centuries and his contemporary critics, like David Nobel and Harry Braverman. Many other disciples also inform the account: histories of urban design and architecture, transport and military history, environmental history and geography.
Verbalising the Visual

Published: July 2017

Verbalising the Visual: Translating Art and Design into Words by Michael Clarke introduces readers to a broad range of language and terminology: formal and informal, academic and colloquial, global and local, all of which can be found in current art and design discourse.
Exploring the complex relationship between language, objects and meaning, Verbalising the Visual shows students how to select and effectively employ language to present oral and written critical assessments of visual culture.
It includes a variety of examples and case studies that explore the many ways in which language is used to discuss, describe, analyze and critically evaluate art and design.
Design By Ikea
Authors: Kristoffersson Sara 
Published: July 2017

Sara Kristoffersson's compelling study provides the first sustained critical history of IKEA. Kristoffersson argues that the company's commercial success has been founded on a neat alignment of the brand with a particular image of Swedish national identity – one that is bound up with ideas of social democracy and egalitarianism - and its material expression in a pared-down, functional design aesthetic. Employing slogans such as “Design for everyone” and “Democratic design”, IKEA signals a rejection of the stuffy, the 'chintzy', and the traditional in both design practices and social structures.
Drawing on original research in the IKEA company archive and interviews with IKEA personnel, Design by IKEA traces IKEA's symbolic connection to Sweden, through its design output and its promotional materials, to examine how the company both promoted and profited from the concept of Scandinavian Design.
Engaging professional staff in the discourse of engagement
Authors: Leece Rhonda , Jaquet Alison 
Published: July 2017

The shift in higher education away from traditional, transactional service models and toward innovative, transformational approaches, has led to a reframing of professional identities. At the University of the Sunshine Coast (USC), the creation of the Student Engagement team in 2015 took a learner-centred, theory-driven and evidence-based approach. However, the new team has been drawn from diverse backgrounds and is building a new, shared identity. To create a common language and understanding of practice in the team, the theory and scholarship of higher education was integrated into team leader discussions. These staff participated in a series of discussions, were encouraged to apply this learning to their daily practice in work with students and in communicating and contextualising their work among staff. The participants have shared their perspective on this new approach and results indicate that, while we are successfully achieving some objectives, the initiative can be adapted to become more effective.
A INFLUÊNCIA DOS PROFISSIONAIS DE SAÚDE SOBRE A PRÁTICA DE ATIVIDADE FÍSICA NO LAZER EM GESTANTES
Authors: Romero Simone Cristina Scarpa , Kurashima Carolina Harumi , Romero Alexandre , Takito Monica Yuri 
Published: July 2017

O objetivo do presente estudo é analisar a associação entre as recomendações recebidas durante o atendimento pré-natal com a prática de atividade física na gestação. Trata-se de um estudo transversal com 290 puérperas. Apenas 9% das mulheres atingiam a recomendação (?150 minutos) de atividade física semanal para manutenção da saúde e 18% praticaram alguma atividade física no lazer (AFL)/exercício físico na gestação. A prática de atividade física anterior à gestação estava associada ao nível de AFL. Adicionalmente, a percepção da presença de recomendação do profissional para a prática de AFL no pré-natal triplicou a chance da mulher ser ativa, ainda que não suficientemente ativa. Ações junto aos profissionais de saúde podem promover modificações no nível de AFL durante a gestação.

La gestión de la terminología en interpretación social a través de dispositivos móviles
Authors: Ortego Antón María Teresa 
Published: July 2017

Los traductores tienen a su disposición una gran cantidad de herramientas y aplicaciones para gestionar la terminología. Sin embargo, los intérpretes sociales, cuya función es permitir a la población que no domina la lengua oficial del país acceder a los servicios básicos y comunicarse con los proveedores de dichos servicios (Shlessinger, 2011: 6), no se han beneficiado del mismo nivel de innovación y su metodología de trabajo todavía sigue siendo rudimentaria y manual. En consecuencia, en este trabajo pretendemos establecer una serie de parámetros basándonos en la literatura precedente para evaluar varias herramientas de gestión terminológica teniendo en cuenta las necesidades de los intérpretes sociales. Con los resultados que obtengamos extraeremos las conclusiones, que señalarán la necesidad de tener en cuenta nuevas propuestas para implementar las herramientas de gestión terminológica para la interpretación social así como de ofrecer nuevos procedimientos de búsqueda a intérpretes sociales tanto profesionales como en formación.

Contemporaneous EMIC and whistler mode waves: Observations and consequences for MeV electron loss
Authors: Zhang X.‐J. , Mourenas D. , Artemyev A. V. , Angelopoulos V. , Thorne R. M. 
Published: July 2017

AbstractThe high variability of relativistic (MeV) electron fluxes in the Earth's radiation belts is partly controlled by loss processes involving resonant interactions with electromagnetic ion cyclotron (EMIC) and whistler mode waves. But as previous statistical models were generated independently for each wave mode, whether simultaneous electron scattering by the two wave types has global importance remains an open question. Using >3 years of simultaneous Van Allen Probes and THEMIS measurements, we explore the contemporaneous presence of EMIC and whistler mode waves in the same L shell, albeit at different local times, determining the distribution of wave and plasma parameters as a function of L, Kp, and AE. We derive electron lifetimes from observations and provide the first statistics of combined effects of EMIC and whistler mode wave scattering on MeV electrons as a function of L and geomagnetic activity. We show that MeV electron lifetimes are often strongly reduced by such combined scattering.
The postearthquake stress state on the Tohoku megathrust as constrained by reanalysis of the JFAST breakout data

Published: July 2017

AbstractThe Japan Trench Fast Drilling Project (JFAST) endeavored to establish the stress state on the shallow subduction megathrust that slipped during the M9 Tohoku earthquake. Borehole breakout data from the drill hole can constrain both the orientation and magnitude of the principal stresses. Here we reanalyze those data to refine our understanding of the stress state on the fault. In particular, we (1) improve the identification of breakouts, (2) consider a fuller range of stress states consistent with the data, and (3) incorporate new and more robust laboratory constraints on rock strength. The original conclusion that the region is in a normal faulting regime after the earthquake is strengthened by the new analysis. The combined analysis suggests that the earthquake released sufficient elastic strain energy to reset the local stress field.
Dependence of nitrite oxidation on nitrite and oxygen in low‐oxygen seawater
Authors: Sun Xin , Ji Qixing , Jayakumar Amal , Ward Bess B. 
Published: July 2017

AbstractNitrite oxidation is an essential step in transformations of fixed nitrogen. The physiology of nitrite oxidizing bacteria (NOB) implies that the rates of nitrite oxidation should be controlled by concentration of their substrate, nitrite, and the terminal electron acceptor, oxygen. The sensitivities of nitrite oxidation to oxygen and nitrite concentrations were investigated using 15N tracer incubations in the Eastern Tropical North Pacific. Nitrite stimulated nitrite oxidation under low in situ nitrite conditions, following Michaelis‐Menten kinetics, indicating that nitrite was the limiting substrate. The nitrite half‐saturation constant (Ks = 0.254 ± 0.161 μM) was 1–3 orders of magnitude lower than in cultivated NOB, indicating higher affinity of marine NOB for nitrite. The highest rates of nitrite oxidation were measured in the oxygen depleted zone (ODZ), and were partially inhibited by additions of oxygen. This oxygen sensitivity suggests that ODZ specialist NOB, adapted to low‐oxygen conditions, are responsible for apparently anaerobic nitrite oxidation.
Nonuniform ocean acidification and attenuation of the ocean carbon sink
Authors: Fassbender Andrea J. , Sabine Christopher L. , Palevsky Hilary I. 
Published: July 2017

AbstractSurface ocean carbon chemistry is changing rapidly. Partial pressures of carbon dioxide gas (pCO2) are rising, pH levels are declining, and the ocean's buffer capacity is eroding. Regional differences in short‐term pH trends primarily have been attributed to physical and biological processes; however, heterogeneous seawater carbonate chemistry may also be playing an important role. Here we use Surface Ocean CO2 Atlas Version 4 data to develop 12 month gridded climatologies of carbonate system variables and explore the coherent spatial patterns of ocean acidification and attenuation in the ocean carbon sink caused by rising atmospheric pCO2. High‐latitude regions exhibit the highest pH and buffer capacity sensitivities to pCO2 increases, while the equatorial Pacific is uniquely insensitive due to a newly defined aqueous CO2 concentration effect. Importantly, dissimilar regional pH trends do not necessarily equate to dissimilar acidity ([H+]) trends, indicating that [H+] is a more useful metric of acidification.

AbstractThe Amundsen Sea polynya (ASP) is reportedly the most productive among the coastal polynyas around Antarctica. However, observational constraints limit our understanding of the biological pump and carbon cycle in the ASP. We measured various carbon‐related parameters such as primary production, bacterial production, sinking flux of particulate organic carbon (POC), and accumulation of organic carbon in the sediment as well as hydrographic parameters during field observations and by instrument moorings. Over 95% of the photosynthetically produced POC was converted to suspended POC and/or dissolved carbon forms in the upper ~400 m layer. We postulate that most of the carbon transported to the water column by the biological pump in the ASP was flushed out of the shelf without being sequestered for long‐term storage in sediments. Lack of bottom water formation due to intrusion of Circumpolar Deep Water in the lower layer reduces carbon sequestration efficiency.

Published: July 2017

AbstractCoronal mass ejections (CMEs), a kind of energetic solar eruptions, are an integral subject of space weather research. Numerical magnetohydrodynamic (MHD) modeling, which requires powerful computational resources, is one of the primary means of studying the phenomenon. With increasing accessibility of such resources, grows the demand for user‐friendly tools that would facilitate the process of simulating CMEs for scientific and operational purposes. The Eruptive Event Generator based on Gibson‐Low flux rope (EEGGL), a new publicly available computational model presented in this paper, is an effort to meet this demand. EEGGL allows one to compute the parameters of a model flux rope driving a CME via an intuitive graphical user interface. We provide a brief overview of the physical principles behind EEGGL and its functionality. Ways toward future improvements of the tool are outlined.
