Published: July 2020

Introdução: A Eletroestimulação Neuromuscular é uma técnica de contração involuntária da musculatura esquelética. Uma vez sobreposta a contração voluntária no treinamento de força, poderá potencializar os efeitos fisiológicos decorrente do treinamento, portanto, essas adaptações ainda não estão totalmente elucidadas na literatura.Objetivo: O objetivo do estudo foi verificar a influência da eletroestimulação neuromuscular concomitante ao treinamento de força sobre os níveis de lactato sanguíneo. Métodos: Participaram do estudo 20 indivíduos do sexo masculino com idade entre 20 e 30 anos. Todos os indivíduos participaram dos 3 protocolos de treinamento de forma aleatória, sendo: cadeira extensora (CE), eletroestimulação (EE) e cadeira extensora com eletroestimulação sobreposta (CE+EE). O lactato foi dosado via sangue venoso e analisado com técnica de espectrofotometria. Os dados estatísticos foram obtidos com auxílio do SPSS 19.0. Resultados: Todos os protocolos de treinamento induziram aumento significativo nos níveis de lactato sanguíneo quando comparado ao repouso (p≤0,05), porém quando feito a comparação entre métodos, o protocolo CE+EE (5,9mmol/L) comparado ao CE (5,6mmol/L) não apresentou diferença estatística significativa (p= 0,433). Conclusão: A eletroestimulação induz aumento nos níveis de lactato, porém quando combinada aos protocolos de treinamento de força, esse aumento não ocorre de forma significativa.
Development of a Mobile Inter-Vehicular Communication System Based on Gossip Algorithm

Published: July 2020

<h1>Mobile Inter-vehicular communication network is an ad hoc network that allows peer vehicles to share and receive data. The existing inter-vehicular communication approach uses data from a limited number of data sources located in distant areas. This leads to high latency caused by the short-range antennas used to connect the peers. Inter-vehicular networks are dynamic and self-organized networks that do not use any external infrastructure to send and receive data. Currently, inter-vehicular networks only exist as part of a hybrid system and hence there is a need for a faster inter-vehicular network which can function independently. In this study, we developed a model which uses the gossip algorithm to send and receive data. The results show that over time, in a peer-to-peer network, the distance to be covered and the delay time are reduced. In the current models, however, the delay and distance covered remain constant. The results show that a peer-to-peer model is faster.</h1><p> </p>
Think Piece: Working for Living - Popular Education as/at Work for Social-ecological Justice
Authors: Burt Jane , James Anna Katharine , Walters Shirley , Von Kotze Astrid 
Published: July 2020

Drawing on the working lives of popular educators who are striving for socioeconomic and socio-ecological justice, we demonstrate how popular education is a form of care work which is feminised, often undervalued and unrecognised as highly skilled work. It is relational work that aims to forge solidarity with communities and the environment. Given the state of the planet, the radical transformations that are needed, and the future projection of ‘work’ as including the care economy in large measure, we argue that popular education is a generative site for further exploration of research into work and learning. However, to move popular education as work from the margins means to rethink the current economic system of value. Addressing the contradiction that undervalues work for life/living, popular education engages transformative action motivated by a deep sense of solidarity and a focus on imagining alternatives as an act of hope.Keywords: work and learning, popular education, care work, solidarity
Challenges of Teaching Akans (Ghana) Culturally-Specific Environmental Ethics in Senior High Schools: Voices of Akans and Biology Teachers
Authors: Opoku Maxwell Jnr , James Angela 
Published: July 2020

Indigenous cultural groups have lived sustainably with their natural resources (land, water bodies, forests, wildlife animals and plants) by employing particular culturallyspecific environmental ethics. These include spiritual perceptions about natural environmental resources, totemic beliefs and taboos. Consequently, many scholars in the country have recommended the integration of these culturally-specific environmental ethics in environmental policies and formal school curricula. The purpose of this research was to explore the views of Akan indigenous knowledge (IK) holders and senior high school Biology teachers on challenges they predicted could confront the teaching of Akan culturally-specific environmental ethics in the senior high school Biology curriculum. An interpretivist paradigm with an ethnographic, naturalistic research style, using in-depth conversational interviews was employed to explore the views of research participants. The perceived challenges included stigma attached to culturally-specific environmental ethics; requirement of proof and experimentation; the use of a foreign language in schools; formal education; loss of the fear for the gods and spirits in nature; centralised curriculum; democracy and political biases. The research concluded that being aware of the possible challenges to the teaching of the Akan culturally-specific environmental ethics can influence policies related to these ethics as well as guide Biology curriculum developers and stakeholders.

When Faulkner Was in Vogue: The American Women's Magazine Fashioning a Modernist Icon
Authors: Yamamoto Yuko 
Published: July 2020

ABSTRACT
This article tracks how American Vogue mediated William Faulkner and his works to its readers from 1927 to 1962, under the editorship of Edna Woolman Chase and Jessica Daves. In so doing this study sheds light on the hitherto overlooked role of American Vogue in promoting, popularizing, and publicizing modernist literature. Using the intersection of Faulkner and Vogue as an exemplary case of the affiliation between literary modernism and popular magazines, this study demonstrates that the postwar canonization of modernism was a joint product of cultural intermediaries choreographed by the New York-based print industry.
Closing the Gap: Examining how the problem of Aboriginal and Torres Strait Islander disadvantage is represented in policy

Published: July 2020

AbstractPolicymaking is increasingly being recognised as a value‐laden process in which social problems are not simply identified and measured, but discursively produced. The current study examined how the problem of Indigenous disadvantage is produced within the original Closing the Gap policy framework, to identify underlying assumptions and problem representations. Bacchi's “What's the Problem Represented to be?” approach was used as the analytic framework, with critical discursive analysis used for a fine‐grained discourse analysis. Findings indicate that the problem of Indigenous disadvantage is produced in culturally limited terms, demonstrates lifestyle drift and relies on deficit‐based narratives of Aboriginal and Torres Strait Islander Australians, which collectively work to produce disadvantage as a product of individual behaviours, and problematises Aboriginal and Torres Strait Islander people as inherently dysfunctional. Potential lived effects of these discourses are discussed, and future areas of research are identified.

Published: July 2020

SummaryThe discrimination of exons from introns in the DNA sequence of a eukaryotic gene is important to understand the functionality of protein formation inside a living organism. Several signal processing techniques involving transforms and filtering have been used to identify the exon regions by exploring the periodicity‐3 property. Fast processing of massive DNA sequences is desirable to detect the disease‐causing mechanism, which is helpful to prepare individual‐centric drugs. In this manuscript, a hardware implementation is carried out for the direct form‐II structure of the infinite impulse response anti‐notch filter to achieve the fast processing of the DNA sequence. Implementation result on Zynq‐series (Zybo board) Field Programmable Gate Array (FPGA) reveals that the proposed implementation is capable to identify the exon regions of five benchmark eukaryotic genes. The FPGA implementation has achieved a maximum clock frequency of 34.629 MHz, which is further improved to 54.41 MHz using the retiming concept. Compared with MATLAB 2014a simulation, the proposed FPGA implementation has achieved similar accuracy with 39 to 43 times faster computing time for the five benchmark data sets. Further, an Application Specific Integrated Circuit (ASIC) implementation is carried out in the CADENCE Register Transfer Level (RTL) compiler tool with GPDK 90‐nm technology, due to which the hardware anti‐notch filter is 120 to 133 times faster compared with its MATLAB counterpart while maintaining the comparable accuracy.
The effect of Biot coefficient and elastic moduli stress–pore pressure dependency on poroelastic response to fluid injection: laboratory experiments and geomechanical modeling
Authors: Raziperchikolaee Samin , Singh Vivek , Kelley Mark 
Published: July 2020

AbstractBiot coefficient and elastic moduli are typically assumed to have a constant value for analyzing poroelastic effects of fluid injection. To investigate the stress–pore pressure dependency of Biot coefficient and elastic moduli, we conducted a series of laboratory experiments on a porous dolomite core sample from a reef in Michigan basin. We varied the confining stress as well as the pore pressure in the experiments. Then, modeling was performed using analytical poroelastic solutions and a coupled two‐phase flow‐geomechanical numerical simulation (for CO2 injection). The modeling results show that the variability of Biot coefficient and elastic moduli should be included in the geomechanical modeling to accurately predict the poroelastic responses of injection (i.e., stress changes and surface uplift). Using a constant stress‐independent Biot coefficient elastic moduli, which is the assumption in poroelastic modeling, leads to underestimation of the stress change and surface uplift due to injection compared to a realistic stress–pore pressure dependent Biot coefficient, which is updated at each time step of injection modeling. Modeling results indicate that decreasing elastic modulus combined with Biot coefficient increase due to the fluid injection could lead to a larger surface uplift and stress changes in the reservoir. In addition, the stress changes and uplift due to injection are a function of initial in situ stress due to Biot coefficient and elastic modulus stress–pore pressure dependency. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd.
Loss of Offsite Power Recovery Modeling in United States Nuclear Power Plants
Authors: Ma Zhegang , Smith Curtis L. , Johnson Nancy E. 
Published: July 2020

ABSTRACTLoss of offsite power (LOOP) can have a major, adverse impact on a nuclear power plant's (NPP) ability to achieve and maintain safe shutdown conditions. The time required for subsequent restoration of offsite power after a LOOP event occurred and the probabilities of LOOP events exceeding various durations (or LOOP non‐recovery probabilities) are important inputs to NPP probabilistic risk assessments (PRA). This paper reviews the analysis of LOOP events at United States commercial NPPs conducted by Idaho National Laboratory (INL) for the US Nuclear Regulatory Commission (NRC). This paper presents the current LOOP recovery modeling that estimates probabilities of LOOP events exceeding various durations (or LOOP non‐recovery probabilities) based on operating experience. NPPs use these LOOP results in PRA models for various risk‐informed activities. Finally, this paper provides the LOOP non‐recovery probability results for the four LOOP categories: plant‐centered, switchyard‐centered, grid‐related, and weather‐related with LOOP recovery data from 1988 to 2018.

BackgroundIn vivo imaging of oxidative stress can facilitate the understanding and treatment of cardiovascular diseases. We evaluated nitroxide‐enhanced MRI with 3‐carbamoyl‐proxyl (3CP) for the detection of myocardial oxidative stress.MethodsThree mouse models of cardiac oxidative stress were imaged, namely angiotensin II (Ang II) infusion, myocardial infarction (MI), and high‐fat high‐sucrose (HFHS) diet‐induced obesity (DIO). For the Ang II model, mice underwent MRI at baseline and after 7 days of Ang II (n = 8) or saline infusion (n = 8). For the MI model, mice underwent MRI at baseline (n = 10) and at 1 (n = 8), 4 (n = 9), and 21 (n = 8) days after MI. For the HFHS‐DIO model, mice underwent MRI at baseline (n = 20) and 18 weeks (n = 13) after diet initiation. The 3CP reduction rate, Kred, computed using a tracer kinetic model, was used as a metric of oxidative stress. Dihydroethidium (DHE) staining of tissue sections was performed on Day 1 after MI.ResultsFor the Ang II model, Kred was higher after 7 days of Ang II versus other groups (p < 0.05). For the MI model, Kred, in the infarct region was significantly elevated on Days 1 and 4 after MI (p < 0.05), whereas Kred in the noninfarcted region did not change after MI. DHE confirmed elevated oxidative stress in the infarct zone on Day 1 after MI. After 18 weeks of HFHS diet, Kred was higher in mice after diet versus baseline (p < 0.05).ConclusionsNitroxide‐enhanced MRI noninvasively quantifies tissue oxidative stress as one component of a multiparametric preclinical MRI examination. These methods may facilitate investigations of oxidative stress in cardiovascular disease and related therapies.

AdS2 type-IIA solutions and scale separation
Authors: Lüst Dieter , Tsimpis Dimitrios 
Published: July 2020

Abstract
In this note we examine certain classes of solutions of IIA theory without sources, of the form AdS2× ℳ(1) × ⋯ × ℳ(n), where ℳ(i) are Riemannian spaces. We show that large hierarchies of curvatures can be obtained between the different factors, however the absolute value of the scalar curvature of AdS2 must be of the same order or larger than the absolute values of the scalar curvatures of all the other factors.
Revolutionary poetry and liquid crystal chemistry: Herman Gorter, Ada Prins and the interface between literature and science
Authors: Zwart Hub 
Published: July 2020

AbstractIn the Netherlands, the poet Herman Gorter (1864–1927) is mostly known as the author of the neo-romantic poem May and the “sensitivistic” Poems, but internationally he became famous as a propagandist of radical Marxism: the author of influential brochures and of an “open letter” to comrade W.I. Lenin in 1920. During the 1890s, Gorter became increasingly dissatisfied with his poetry, considering it as ego-centric, disinterested and “bourgeois”, unconnected with what was happening in the real (material-political) world. He wanted to put his poetry on a scientific footing, notably by endorsing a dialectical materialist worldview. In the communist society he envisioned, science would become poetry and poetry would become science. In his opus magnum Pan (11,000 lines of verse, published in 1916), two terms are rather prominent, namely heelal (“universe”) and kristal (“crystal”). These signifiers not only reflect important themes, but also two friendships which began around 1900, namely with prominent astronomer and marxist Anton Pannekoek (who studied the universe) and with Ada Prins, the first woman in the Netherlands who acquired a PhD in chemistry, specialised in liquid crystal research. Whereas Ada Prins is mostly remembered as one of Gorter’s secret lovers, she was first and foremost his educated guide into the complex and enigmatic world of twentieth-century chemistry research. Liquid crystal chemistry became an important source of inspiration for Gorter’s work and the main objective of this paper is to demonstrate her influence on Gorter’s Pan as a scientific poem After presenting the two heroes of this paper, and their work in poetry and chemistry respectively, I will analyse the role of liquid crystals in Herman Gorter’s Pan, highlighting important connections with Ada Prins’ research into liquid crystal chemistry.
New alliances in global environmental governance: how intergovernmental treaty secretariats interact with non-state actors to address transboundary environmental problems
Authors: Hickmann Thomas , Elsässer Joshua Philipp 
Published: July 2020

AbstractThe past few years have witnessed a growing interest among scholars and policy-makers in the interplay of international bureaucracies with civil society organizations, non-profit entities, and the private sector. Authors concerned with global environmental politics have made considerable progress in capturing this phenomenon. Nevertheless, we still lack in-depth empirical knowledge on the precise nature of such institutional interlinkages across governance levels and scales. Building upon the concept oforchestration, this article focuses on the relationship between specific types of international bureaucracies and actors other than the nation-state. In particular, we investigate how the secretariats of the three Rio Conventions reach out to non-state actors in order to exert influence on the outcome of international environmental negotiations. Our analysis demonstrates that the three intergovernmental treaty secretariats utilize various styles of orchestration in their relation to non-state actors and seek to push the global responses to the respective transboundary environmental problems forward. This article points to a recent trend towards a direct collaboration between these secretariats and non-state actors which gives rise to the idea that new alliances between these actors are emerging in global environmental governance.
Green building in China
Authors: Shen Yayun , Faure Michael 
Published: July 2020

AbstractGreen buildings can play a role in helping countries meet their commitments under the Paris Agreement on Climate Change. Green building can provide an important contribution to sustainability, for example, by improving energy efficiency, by improving indoor air quality, and by effective waste treatment. In practice, we see that there is an increasing interest in various forms of green building. However, the existing literature has not identified the role of law in promoting green building. It is, moreover, striking that green building has taken off in a rather impressive manner in China. Although generally there are still huge environmental problems with which China is confronted, for many years already China has been engaged in green building. This paper wants to examine what explains the relative success of green building in China; What specific legal instruments can be used to promote green building; and what lessons can be drawn more generally from experience in China? The paper uses the theory of smart regulation (Gunningham/Grabosky) and the economic analysis of law to examine the importance of different instruments in promoting green building. The paper comes to two key results, being that no single instrument in itself is optimal to promote green building as a result of which a smart mix needs to be designed to promote green building; moreover, for the specific case of China, it is the large government involvement in the economy that has been able to jump-start green building. The Chinese government has, on the one hand, mandated green building in government projects, but on the other hand, also used market-based instruments (like subsidies and public procurement) to promote green building.
An extended energy balance method for resonance prediction in forced response of systems with non-conservative nonlinearities using damped nonlinear normal mode
Authors: Sun Yekai , Vizzaccaro Alessandra , Yuan Jie , Salles Loïc 
Published: July 2020

AbstractThe dynamic analysis of systems with nonlinearities has become an important topic in many engineering fields. Apart from the forced response analyses, nonlinear modal analysis has been successfully extended to such non-conservative systems thanks to the definition of damped nonlinear normal modes. The energy balance method is a tool that permits to directly predict resonances for a conservative system with nonlinearities from its nonlinear modes. In this work, the energy balance method is extended to systems with non-conservative nonlinearities using the concept of the damped nonlinear normal mode and its application in a full-scale engineering structure. This extended method consists of a balance between the energy loss from the internal damping, the energy transferred from the external excitation and the energy exchanged with the non-conservative nonlinear force. The method assumes that the solution of the forced response at resonance bears resemblance to that of the damped nonlinear normal mode. A simplistic model and full-scale structure with dissipative nonlinearities and a simplistic model showing self-excited vibration are tested using the method. In each test case, resonances are predicted efficiently and the computed force–amplitude curves show a great agreement with the forced responses. In addition, the self-excited solutions and isolas in forced responses can be effectively detected and identified. The accuracy and limitations of the method have been critically discussed in this work.

Published: July 2020

AbstractThe atomic distribution in amorphous FeZr alloys is found to be close to random, nevertheless, the composition can not be viewed as being homogenous at the nm-scale. The spatial variation of the local composition is identified as the root of the unusual magnetic properties in amorphous $$\hbox {Fe}_{1-x}\hbox {Zr}_{x}$$Fe1-xZrx alloys. The findings are discussed and generalised with respect to the physical properties of amorphous and crystalline materials.
