Pleistocene-Holocene tectonic reconstruction of the Ballık travertine (Denizli Graben, SW Turkey): (De)formation of large travertine geobodies at intersecting grabens
Authors: Van Noten Koen , Topal Savaş , BAYKARA M. , Özkul Mehmet , Claes Hannes , Aratman Cihan , Swennen Rudy
Published: September 2018

Travertine geobodies have been identified as potential reservoir analogues to carbonate build-ups in pre-salt hydrocarbon systems. To investigate travertine geobody deformation, faults were mapped in 35 travertine quarries that excavate the Ballık travertine, i.e. a c. 12.5 km2 large travertine geobody that precipitated at the intersection of the NE margin of the Denizli Basin and neighbouring Baklan Graben (SW Turkey). This travertine precipitated from cooling carbonate-saturated thermal spring waters that resurfaced along the margin fracture/fault network and through Neogene unconsolidated underlying sediments. From the Denizli basin floor to the uplifted graben shoulders, fault orientation is dominantly WNW-ESE oriented with major basin faults showing a left-stepping trend. Along the upper Denizli margin, travertine is only deformed by extensional normal faults. Along the lower margin, travertine starts with a subhorizontal facies but evolves to a travertine facies formed by a sloping topography with a domal architecture. Paleostress inversion of fault-slip data reveals that an Early Pleistocene NNE-SSW extensional-transtensional phase initiated the WNW-ESE oriented, graben-facing normal fault network. In the Middle Pleistocene, the Ballık fault network was left-lateral strike-slip reactivated because it acted as a transfer zone between the NW-SE extending neighbouring Baklan Basin and NW-SE extension along NE-SW oriented margin faults of the DGHS. In this stress configuration, travertine precipitated along the SW margin fault of the Baklan Graben. After strike-slip reactivation, a Late Pleistocene-to-current NNE-SSW extensional stress regime reinstalled during which margin faults widened and active travertine precipitation moved to more central parts of the DGHS. As different tectonic regimes affect graben intersections, reservoir analogues can have a complex deformation history driven by fault reactivation and recurrent stress permutations. This study concludes that large travertine geobodies can form at graben intersections because of their susceptibility to enhanced fluid flow through the complex fault-fracture network.
Exploring marine spatial planning education: Challenges in structuring transdisciplinarity
Authors: GISSI ELENA , de Vivero Juan Luis Suarez
Published: September 2018

Marine Spatial Planning (MSP) has experienced vigorous growth on the international scale in recent years, and several practices has emerged from different countries. The demand for specific training in the preparation and implementation of marine planning has therefore already shown itself to be quite relevant on a global scale. Educational initiatives related to MSP have to respond to the increased complexity of MSP, which integrates environmental and economic perspectives on marine resources and maritime sectors, considering governance framework as well as maritime affairs and legislation.This paper aims at addressing the educational and training needs for the development of both academic education and professional training in MSP. Learning skills, contents and methods of an ‘ideal’ MSP course are depicted from widely accepted operative guides on MSP and from the EU Framework Directive on MSP (2014/89/EU). They are considered for the analysis of the current educational offer around MSP, performed in a sample of countries that have already undergone a process of implementation of MSP by Law. As result, beside the great variety of courses, it emerges that MSP education seems to be often regarded from an environmental perspective – in continuity with Integrated Coastal Management education – while planning theory and experiences in MSP are the least represented contents. Results are discussed in relation to three major challenges: i) how educational offer reflects on transdisciplinarity, ii) the role of theory in MSP courses, and iii) the enforceability of Plans as major concern in MSP.
Un-gendering the ocean: Why women matter in ocean governance for sustainability
Authors: GISSI ELENA , Michelle Portman , Hornidge Anna-Katharina
Published: September 2018

This viewpoint emphasizes gendered perspectives and reflects on gender roles for sustainability-focused governance. It argues that when considering gender in this context, not only equity, or power-plays between genders are at stake; in addition, for effective ocean governance, an irreducible contribution of female voices is necessary. Some key contributions of women in the field of ocean governance-related research are described as examples. If women, for instance, are not included in fisheries management, we miss the complete picture of social-ecological linkages of marine ecosystems. Overall, women are often regarded as major actors driving sustainable development because of their inclusiveness and collaborative roles. Similarly, women have advocated for the common good in marine conservation, raising important (and often neglected) concerns. In maritime industries, women enlarge the talent pool for innovation and smart growth. Besides the manifold possibilities for promoting the involvement of women in ocean governance and policy-making, this viewpoint highlights how gendered biases still influence our interactions with the ocean. It is necessary to reduce the structural, and systemically-embedded hurdles that continue to lead to gendered decision-taking with regard to the ocean.
Identity concerns drive belief: The impact of partisan identity on the belief and dissemination of true and false news
Authors: Pereira Andrea , Harris Elizabeth Ann , Van Bavel Jay Joseph
Published: September 2018

We test three competing theoretical accounts invoked to explain the rise and spread of political (mis)information. We compare the ideological values hypothesis—people prefer news that bolsters their values and worldviews; the confirmation bias hypothesis—people prefer news that fits their pre-existing stereotypical knowledge; and the political identity hypothesis—people prefer news that allows them to believe positive things about political in-group members and negative things about political out-group members. In three experiments (N = 1420), participants from the United States read news describing actions perpetrated by their political in-group or out-group. Consistent with the political identity hypothesis, Democrats and Republicans were both more likely to believe news about the value-upholding behavior of their in-group or the value-undermining behavior of their out-group. Belief was positively correlated with willingness to share on social media in all conditions, but Republicans were more likely to believe and want to share apolitical fake news.
Links between behaviour change techniques and mechanisms of action: an expert consensus study
Authors: Connell Bohlen Lauren , Carey Rachel Naomi , de Bruin Marijn , Rothman Alexander , Johnston Marie , Kelly Michael P , Michie Susan
Published: September 2018

BACKGROUND: Understanding the mechanisms through which behaviour change techniques (BCTs) can modify behaviour is important for the development and evaluation of effective behavioural interventions. To advance the field, we require a shared knowledge of the mechanisms of action (MoAs) through which BCTs may operate when influencing behaviour. PURPOSE: To elicit expert consensus on links between BCTs and MoAs. METHODS: In a modified Nominal Group Technique study, 105 international behaviour change experts rated, discussed, and re-rated links between 61 frequently used BCTs and 26 MoAs. The criterion for consensus was that at least 80% of experts reached agreement about a link. Heat maps were used to present the data relating to all possible links. RESULTS: Of 1,586 possible links (61 BCTs × 26 MoAs), 51 of 61 (83.6%) BCTs had a definite link to one or more MoAs (mean (SD) = 1.44 (0.96), range= 1-4), and 20 of 26 (76.9%) MoAs had a definite link to one or more BCTs (mean (SD) = 3.27 (2.91), range=9). Ninety (5.7%) were identified as ‘definite’ links, 464 (29.2%) as ‘definitely not’ links, and 1032 (65.1%) as ‘possible’ or ‘unsure’ links. No ‘definite’ links were identified for 10 BCTs (e.g. ‘Action Planning’ and ‘Behavioural Substitution’) and for six MoAs (e.g. ‘Needs’ and ‘Optimism’).CONCLUSIONS: The matrix of links between BCTs and MoAs provides a basis for those developing and synthesizing behavioural interventions. These links also provide a framework for specifying empirical tests in future studies. Note: This article has been accepted for publication in Annals of Behavioral Medicine.

Screening word usage in people affected by PTSD: an unbiased, cost effective, and novel screening method?
Authors: Todorov German I. , Mayilvahanan Karthikeyan , Cain Christopher K , Cunha Catarina
Published: September 2018

According to the World Health Organization, mental illness is the leading cause of disability worldwide accounting for 37% of years of healthy life lost. Prevention and early detection of mental health disorders is important for social stability and economic prosperity of every country and the world at large. Posttraumatic Stress Disorder (PTSD) is a very common condition with more than 3 million cases per year in the US alone. PTSD symptoms usually start soon after a traumatic event. The right diagnosis in a timely manner is key to ensuring prompt treatment that could lead to a full recovery. Unfortunately, social stigma as well as self-presentation and self-assessment biases often prevent individuals from seeking timely evaluation, leading to delays in treatment and suboptimal outcomes. Previous studies show that various mental health conditions are associated with distinct patterns of language use. Analyzing language use may also help to avoid response bias in self-reports. In this study we show a number of language use differences between PTSD sufferers and controls. Our data also suggest that subgroups of people with the same mental health disorder (PTSD in this study) may have salient differences in their language use, particularly in word usage frequencies. Additionally, we show that word usage patterns may vary depending on the type of the text being analyzed. These factors need to be accounted for when creating screening tools based on language analysis. If properly developed, such tools may facilitate earlier PTSD diagnosis, leading to timely support and treatment, which are associated with better outcomes.

Property Rights that 'Work' in the Face of Disaster: Per Share Joint Ownership of Arable in Early Modern and Modern Japan
Authors: Brown Philip C.
Published: September 2018

Early Modern and early Modern Japanese certainly attempted to control floods, landslides and water insufficiency/drought via direct manipulation of land. In addition, about one third of pre-modern Japanese villages were subject to joint land ownership regimes, the most common of which distributed risks and benefits of natural characteristics proportionally among landholders and tenants alike. It represents one very sophisticated anticipatory form of sharing the risks and advantages associated with arable land. It maximised the potential for all to continue as agriculturalists and contributors to community labors (irrigation maintenance, dike maintenance, shrines, and more) as well as to continue as tenants. The landholding system also dictated the response to the loss of land from floods or landslides. Begun by the early seventeenth century, a reduced number of hamlets continued this practice down to the 1970s. The long history of joint ownership across multiple political regimes - Early Modern, pre-World War II modern, and post-war modern Japan begs us to embrace a broader conception of landed property rights than the ideal types of 'fee simple/private' and 'commons', and the relationship between rights in practice and those embodied in law. A review of the most widely used form of joint ownership suggests the potential power for local organisations using local knowledge of a resource to create effective property rights that help address challenges presented by catastrophic natural events.
Reforming Mineral Ownership and Ensuring Surface Owners' Rights: The Gosselies Disaster
Authors: Troch Kevin
Published: September 2018

In interwar Belgium, coal mining suffered a double, socioeconomic and environmental, crisis. The rise in coal production went along with increased mining damage. The cost of the damage became so high that mining companies were unable to bear it. In 1934, a disaster in the town of Gosselies revealed the weakness of the Belgian mining industry. The town was disfigured by the effects of surface subsidence caused by the Grand Conty and Spinois mining company. Unable to make compensation to victimised surface owners, the company declared itself bankrupt. The Belgian state was then faced with an unprecedented environmental crisis threatening to jeopardise the future of coal extraction in the country. The disaster was an opportunity to reconsider the mineral ownership regime and ensure better compensation for surface owners by placing the regulation of mining damage under administrative oversight.
Mitigating Disaster: The Aral Sea and (Post-)Soviet Property
Authors: Wheeler William
Published: September 2018

The Aral Sea regression, the outcome of Soviet irrigation practices in Central Asia, is famous as one of the most serious ecological disasters of the twentieth century. This article examines Soviet policies to mitigate the sea's regression, in particular efforts to keep people in employment. I argue that property relations are intimately connected not only with the causes of environmental change but also with its effects, and explore this proposition through three case studies. First, I use archival materials to show how late Soviet bureaucrats framed the regression not as an environmental disaster but as a problem of living standards and employment, which shaped measures to address it. Secondly, I examine memories of the late Soviet period among fishermen in Aral villages, arguing that their experiences of the sea's regression were shaped both by their position within the Soviet fishery and by local understandings of property. Finally, I explore nostalgic narratives in the town of Aral'sk today, arguing that the history of environmental change is re-read through post-Soviet changes in property relations.

Per-session security: Password-based cryptography revisited
Authors: Demay Grégory , Gaži Peter , Maurer Ueli , Tackmann Björn
Published: September 2018

Cryptographic security is usually defined as a guarantee that holds except when a bad event with negligible probability occurs, and nothing is guaranteed in that bad case. However, in settings where such failure can happen with substantial probability, one needs to provide guarantees even for the bad case. A typical example is where a (possibly weak) password is used instead of a secure cryptographic key to protect a session, the bad event being that the adversary correctly guesses the password. In a situation with multiple such sessions, a per-session guarantee is desired: any session for which the password has not been guessed remains secure, independently of whether other sessions have been compromised. A new formalism for stating such gracefully degrading security guarantees is introduced and applied to analyze the examples of password-based message authentication and password-based encryption. While a natural per-message guarantee is achieved for authentication, the situation of password-based encryption is more delicate: a per-session confidentiality guarantee only holds against attackers for which the distribution of password-guessing effort over the sessions is known in advance. In contrast, for more general attackers without such a restriction, a strong, composable notion of security cannot be achieved.
Towards a visuo-dynamic interface for disability self-assessment
Authors: Rybarczyk Yves Philippe , Vernay Didier
Published: September 2018

BACKGROUND:

The Therapeutic Patient Education (TPE) aims to help patients to understand diseases and treatments, and collaborate in healthcare by taking an active role in the management of a chronic disease. This transition from the classical patient compliance to empowerment is a revolutionary concept in medicine. However, this consensual idea is not easy to implement because of the complexity of medical records, which are designed for health professionals only.

OBJECTIVE:

In order to enhance the TPE, an intuitive tool based on a visuo-dynamic interface was developed to facilitate the self-evaluation of disability situations.

METHODS:

The paper describes the whole implementation process to implement such a user interface, from the development of an innovative low cost markerless motion capture to the 3D modeling of everyday life activities.

RESULTS:

A usability test carried out on twenty disabled people shows that participants are more at ease to perform a self-assessment of their motor disabilities through an animated stickman-based interface than a classical static interface.

CONCLUSIONS:

Considering the promising results of this study, the next step of this project will consist of integrating the visuo-dynamic interface into an existing platform (e-ESPOIRS-Handi) dedicated to information sharing between health professional and disabled people.
Automation of audio descriptions of large bar charts for persons with visual impairment: Prototyping and proof of concept
Authors: Gunnarsson Celie , Hammenberg Julia , Bornemalm Karolina , Rassmus-Gröhn Kirsten
Published: September 2018

BACKGROUND:

Current guidelines for accessing graphs non-visually are based on giving access to underlying tabular data and reading the values one by one. When data sets are large, it becomes impossible to get an overview.

OBJECTIVE:

This work presents a proof-of-concept of automated audio description of data sets up to 100 data points that can be used by persons with visual impairment or persons who for other reasons are unable to use their visual attention for data access.

METHODS:

A pilot study was conducted to elicit guidelines for oral chart descriptions, after which lo-fi and hi-fi prototypes were designed. Visually impaired and sighted users were involved throughout the process.

RESULTS:

The pilot study pinpointed important issues of oral chart descriptions and provided input for a lo-fi-prototype with three variants. The lo-fi-prototype singled out the most successful way of describing the charts based on which a hi-fi prototype for large data sets was created and tested.

CONCLUSIONS:

The results of the hi-fi tests are promising. Participants listened 1–2 times to the descriptions and were able to discuss details in the data. Thus, the initial guidelines and the following design process provided the necessary information to create a successful proof-of-concept.

Authors: Tay Ee Lin , Lee Shaun Wen Huey , Yong Geok Har , Wong Chee Piau
Published: September 2018

BACKGROUND:

There have been several reviews examining the effectiveness of VR in rehabilitation. However, its effectiveness remains inconclusive in most review articles.

OBJECTIVE:

To explore the effectiveness of customized game based virtual rehabilitation on the physical recovery of patients with acquired brain injury.

METHOD:

We searched PubMed, MEDLINE, EMBASE, CINAHL, CENTRAL, PsycINFO and AMED for articles published until 30[Formula: see text] June 2017. Articles that met the study’s inclusion/exclusion criteria were included in the review.

RESULTS:

A total of 31 studies were selected for review. Pooled analysis showed that customized game-based virtual rehabilitation was effective in improving balance, gait and upper limb functioning as assessed via Berg Balance Scale (BBS) (WMD: 3.31, 95% CI 0.79 to 5.82); Timed Up and Go test (WMD: [Formula: see text]4.48, 95% CI [Formula: see text]5.43 to [Formula: see text]3.52); walk tests (SMD: 0.47, 95% CI 0.05 to 0.89), and Fugl-Meyer Assessment (SMD 0.46, 95% CI 0.20 to 0.72; [Formula: see text] 0.01). Generally, most studies reported that participants were more motivated and enjoyed the game based intervention although there were some mixed results.

CONCLUSION:

Customized game based virtual rehabilitation has potential to complement current rehabilitation programs. Participants’ subjective reports of well-being, motivation and acceptance towards this intervention were generally positive.
INTERAÇÃO DE TARTARUGAS MARINHAS E A PESCA NO BRASIL: UMA REVISÃO DA LITERATURA
Authors: Gagliardi Talita Ribeiro , Lopes Thaís Cândido , Serafini Thiago Zagonel
Published: September 2018

A pesca no Brasil é bastante diversificada, abrangendo comunidades pesqueiras artesanais distribuídas ao longo da costa, além de frotas industriais. Das sete espécies de tartarugas marinhas que ocorrem ao redor do mundo, cinco são encontradas no Brasil e todas interagem com a pesca. Esforços de pesquisa e conservação visando mitigar a captura incidental (bycatch) das tartarugas vem sendo realizados, sendo considerada uma linha de ação prioritária para a pesquisa, manejo e conservação. Com o objetivo de compreender de que maneira a pesquisa vem lidando com a questão da interação das tartarugas marinhas com a pesca no Brasil, no presente trabalho realizamos uma revisão da literatura visando identificar os avanços e as lacunas do conhecimento sobre a temática no país. Foi identificada uma literatura crescente desde os anos de 1960, com um aumento mais expressivo a partir dos anos 2000. Apesar do aumento das pesquisas, observamos um predomínio da literatura sobre a interação com a pesca industrial, em especial o espinhel pelágico, em detrimento de pescarias artesanais, a qual ainda carece de estudos, principalmente nas regiões norte e nordeste. Ainda, se faz necessário um melhor dimensionamento da mortalidade ocasionada pela captura na pesca e seu impacto nas populações, assim como na ampliação das estratégias de conservação.

A eficiência técnica na carcinicultura depende cada vez mais da qualidade dos insumos empregados na produção e das práticas de manejo realizado na fazenda. Esta pesquisa teve como objetivo descrever as boas práticas, produtivas e ambientais, adotadas pela carcinicultura, no estado do Ceará, e avaliar a relação entre essas práticas e a produtividade de camarão cultivado neste estado. Para efetuar os testes de significância das práticas adotadas, uma amostra de 60 fazendas de engorda de camarão foi coletada e utilizada para estimar um modelo de regressão semi-logarítmica. Os resultados mostraram que as fazendas amostradas possuíam nível médio de adoção das boas práticas e que aquelas voltadas para a melhoria da qualidade ambiental na fazenda não afetaram significativamente a produtividade média, evidenciando que a busca da eficiência técnica produtiva tem sido a prioridade nas fazendas.
THE IMPORTANCE OF CEARÁ STATE TO THE BRAZILIAN MARINE ORNAMENTAL FISH EXPORTS
Authors: De Gurjão Lívio Moreira , Lotufo Tito Monteiro da Cruz
Published: September 2018

O Brasil é um dos principais fornecedores mundiais de peixes ornamentais marinhos e Ceará é o estado exportador de maior relevância no país. Entretanto, existe uma carência de informações atualizadas sobre a atividade, o que é crucial para a explotação sustentável desses organismos. Assim, o presente trabalho fornece os dados mais recentes em relação às exportações brasileiras e, mais especificamente, cearenses de peixes ornamentais marinhos, por meio da análise de informações contidas em 420.871 autorizações de exportação emitidas pelas autoridades ambientais brasileiras nos últimos 10 anos. Os resultados corroboram a relevante paraticipação do estado do Ceará nas exportações nacionais de peixes ornamentais marinhos, mas também mostram um declínio substancial dessa atividade ao longo da última década. Dezesseis espécies foram as mais abundantes e frequentes tanto nas exportações brasileiras quanto nas cearenses. Não surpreendentemente, os pomacantídeos foram os peixes mais importantes comercializados, e provavelmente mais de 283.525 indivíduos foram capturados na natureza em um intervalo de aproximadamente 10 anos. Atualmente as exportações brasileiras são direcionadas principalmente para os países asiáticos e deslocamentos sazonais da Zona de Convergência Intertropical (ZCIT) parecem interferir na coleta de peixes ornamentais no Ceará, impactando
Peranan Komunikasi Dakwah dalam Meluruskan Metode Dakwah Islam Radikal di Indonesia
Authors: Prianto Agung Teguh
Published: September 2018

Radical Islam movements in Indonesia have different historical roots but have some similarities on their methods of dakwah movement, which are both rigid and strict in implementing their teachings, such as imposing people’s will, enforcing Islamic law and easily setting the fellow Moslems up as disbelievers. These teachings frequently experience clashes with the country and society when they are implemented in Indonesia, both among Moslems and with non-Moslems. Therefore, It is necessary to have the right way for communicating dakwah; how to convey dakwah messages in Islamic teachings to be well accepted in society. This research uses literature study method and is approached by theories of dakwah communication. By this approach, we can identify the weakness of radical Islam movements related to their dakwah in society. We can also find out that messages in Islam are the ones which bring peace, justice and tolerance; not ones which deprive people’s rights and impose people’s will.

Authors: Nguyen Thuan Thi Thanh , Cao Anh Thuy , Le Huy Quang , Nguyen Dung Thi Bao
Published: September 2018

Applying the methodology of the Intergovernmental Panel on Climate Change (IPCC) in calculating the greenhouse gas emission from pig farming operations at Lam Dong province in 2015, calculated results show that the application of swine manure management solutions can significantly reduce emissions of greenhouse gases into the environment. Using of energy in pig farming operations around 0.0007 tCO2 emissions/ head/ month, the digestion of pig feed create a greenhouse gas emission at around 152.96 tCO2/month with emission factor of 0.0029 tCO2/head / month. Greenhouse gases emitted from the current manure management system (manure are treated by various forms and the rest will directly disposed into the environment) into the atmosphere is around 400.08tCO2/month, respectively a pig emitted about 0.0076 tCO2/head/month. The total emission factor during pig production under the scenarios: (1) manure are directly discharged into the environment, (2) manure are managed by current management system, (3) manure are managed by current management systems with the gas generated from biogas recovery is converted into electrical energy and (4) manure are managed by Biogas recovery system, respectively 0.0593; 0.0112; 0.0101; 0.0077 tCO2/ head/month.
High-energy electroproduction in an atomic field
Authors: Krachkov P A , Milstein A I
Published: September 2018

We discuss the most recent results in studies of high-energy electroproduction in an atomic field. Production of an e+e− pair by a relativistic electron, relativistic muon, or light nucleus and production of a μ
+
μ
− pair by a relativistic electron are reviewed. We focus on an accurate account of the interaction of the incoming particle and produced pair with the atomic field (Coulomb corrections). In all the considered cases, interaction of the particle that produces a virtual photon with the atomic field is shown to significantly change the differential cross section of the process (differential with respect to the momentum of the photon-emitting particle), in disagreement with the generally accepted opinion. However, the process cross section integrated over that momentum is only weakly affected by the interaction. Pair production in an unbound or bound state (positronium, muonium, and dimuonium) is discussed.

Diabetes mellitus (DM) often causes chronic inflammation, hypertrophy, apoptosis and fibrosis in the heart and subsequently leads to myocardial remodeling, deteriorated cardiac function and heart failure. However, the etiology of the cardiac disease is unknown. Therefore, we assessed the gene expression in the left ventricle of diabetic and non-diabetic mice using Affymetrix microarray analysis. Allograft inflammatory factor-1 (AIF-1), one of the top downregulated B cell inflammatory genes, is associated with B cell functions in inflammatory responses. Real-time reverse transcriptase-polymerase chain reaction confirmed the Affymetrix data. The expression of CD19 and AIF-1 were downregulated in diabetic hearts as compared to control hearts. Using in vitro migration assay, we showed for the first time that AIF-1 is responsible for B cell migration as B cells migrated to GFP-AIF-1-transfected H9C2 cells compared to empty vector-transfected cells. Interestingly, overexpression of AIF-1 in diabetic mice prevented streptozotocin-induced cardiac dysfunction, inflammation and promoted B cell homing into the heart. Our results suggest that AIF-1 downregulation inhibited B cell homing into diabetic hearts, thus promoting inflammation that leads to the development of diabetic cardiomyopathy, and that overexpression of AIF-1 could be a novel treatment for this condition.
Measurements versus Numerical Simulations for Slotted Synthetic Jet Actuator

In many studies concerning synthetic jet flow fields the analysis is usually restricted to simple configurations, such as a single diaphragm oscillating in a cylindrical cavity, which is linked to the external environment with only one orifice/slot. Nonetheless, in many applications the requirement of small sizes and weights leads to many implementation issues, such as asymmetric actuator geometries, presence of several slots and diaphragms and irregular cavity shapes. Therefore, the design of a synthetic jet actuator for a specific flow control problem requires a dedicated study in order to characterize its behavior even in quiescent conditions. The aim of this work is to investigate the behavior of a novel synthetic jet actuator, composed of three independent diaphragms, acting on a single cavity, and linked to the external environment through four slots per diaphragm. The device has been studied in quiescent conditions, both numerically and experimentally. The experimental investigation has been carried out by means of hot-wire measurements. In particular, the distribution of the phase-averaged streamwise velocity along the slot spanwise direction has been detected near the slot exit plane. From the computational side, incompressible direct numerical simulations have been carried out using the open-source OpenFOAM code. The diaphragm motion is mimicked by a inhomogeneous inlet boundary condition, whose amplitude is chosen to match the experimental velocity at the exit plane. A fair agreement between the numerical and the experimental results is achieved for both the velocity field at the slot exit and the main non-dimensional parameters of the synthetic jet. After the validation, the numerical results are finally processed, to obtain information about the vortex motion in the external environment.

Published: September 2018

Stresses in structures are usually converted by measured strains based on corresponding constitutive relations of materials. However, it is difficult to determine the constitutive relation of the material accurately, which leads to significant uncertainty of the converted stresses. This paper proposed a method to estimate the stresses in concrete by using the coda wave interference technique and established a model to describe the relation between the deformation of microcracks and the sound velocity. Based on the experiments, the development law of the coda waves with different frequencies of sound signal propagating in concrete was verified and discussed, and the change of the coda wave velocity during the loading and unloading of the specimen was tested. Parameters involved in the established model were regressed according to the experimental data. The analysis results show that the method can be used to test concrete stress and has a desirable accuracy.
Towards Online Estimation of Human Joint Muscular Torque with a Lower Limb Exoskeleton Robot

Exoskeleton robots demonstrate promise in their application in assisting or enhancing human physical capacity. Joint muscular torques (JMT) reflect human effort, which can be applied on an exoskeleton robot to realize an active power-assist function. The estimation of human JMT with a wearable exoskeleton is challenging. This paper proposed a novel human lower limb JMT estimation method based on the inverse dynamics of the human body. The method has two main parts: the inverse dynamic approach (IDA) and the sensing system. We solve the inverse dynamics of each human leg separately to shorten the serial chain and reduce computational complexity, and divide the JMT into the mass-induced one and the foot-contact-force (FCF)-induced one to avoid switching the dynamic equation due to different contact states of the feet. An exoskeleton embedded sensing system is designed to obtain the user’s motion data and FCF required by the IDA by mapping motion information from the exoskeleton to the human body. Compared with the popular electromyography (EMG) and wearable sensor based solutions, electrodes, sensors, and complex wiring on the human body are eliminated to improve wearing convenience. A comparison experiment shows that this method produces close output to a motion analysis system with different subjects in different motion.

Ionic liquids (ILs) have been reported to be good process aids for enhanced bitumen recovery from oil sands. However, after the extraction, some ionic liquids are left in the residual solids or solutions. Herein, a washing–ion exchange combined method has been designed for the removal of two imidazolium-based ILs, ([Bmim][BF4] and [Emim][BF4]), from residual sands after ILs-enhanced solvent extraction of oil sands. This process was conducted as two steps: water washing of the residual solids to remove ILs into aqueous solution; adsorption and desorption of ILs from the solution by the sulfonic acid cation-exchange resin (Amberlite IR 120Na). Surface characterization showed that the hydrophilic ionic liquids could be completely removed from the solid surfaces by 3 times of water washing. The ionic liquids solution was treated by the ion-exchange resin. Results showed that more than 95% of [Bmim][BF4] and 90% of [Emim][BF4] could be adsorbed by the resins at 20 °C with contact time of 30 min. The effects of some typical coexisted chemicals and minerals, such as salinity, kaolinite (Al4[Si4O10](OH)8), and silica (SiO2), in the solution on the adsorption of ionic liquids have also been investigated. Results showed that both kaolinite and SiO2 exerted a slight effect on the uptake of [Bmim][BF4]. However, it was observed that increasing the ionic strength of the solution by adding salts would deteriorate the adsorption of [Bmim]+ on the resin. The adsorption behaviors of two ILs fit well with the Sips model, suggesting the heterogeneous adsorption of ionic liquids onto resin. The adsorption of ionic liquids onto Amberlite IR 120Na resin was found to be pseudo-second-order adsorption. The regeneration tests showed stable performance of ion-exchange resins over three adsorption–desorption cycles.
An Ant-Lion Optimizer-Trained Artificial Neural Network System for Chaotic Electroencephalogram (EEG) Prediction
Authors: Kose Utku
Published: September 2018

The prediction of future events based on available time series measurements is a relevant research area specifically for healthcare, such as prognostics and assessments of intervention applications. A measure of brain dynamics, electroencephalogram time series, are routinely analyzed to obtain information about current, as well as future, mental states, and to detect and diagnose diseases or environmental factors. Due to their chaotic nature, electroencephalogram time series require specialized techniques for effective prediction. The objective of this study was to introduce a hybrid system developed by artificial intelligence techniques to deal with electroencephalogram time series. Both artificial neural networks and the ant-lion optimizer, which is a recent intelligent optimization technique, were employed to comprehend the related system and perform some prediction applications over electroencephalogram time series. According to the obtained findings, the system can successfully predict the future states of target time series and it even outperforms some other hybrid artificial neural network-based systems and alternative time series prediction approaches from the literature.

Published: September 2018

The very high cycle fatigue (VHCF) property of TC21 titanium alloy blunt-notched specimens were investigated by using an ultrasonic fatigue test machine with a frequency of 20 kHz. S–N of blunt-notched specimens illustrated a continuous decrease characteristic with a horizontal line over the 105–109 cycle regimes. However, the fatigue life showed a large scatter for blunt-notched specimens. Blunt-notch significantly reduced the fatigue property in the high cycle and very high cycle regimes compared with that of smooth specimens. The crack initiation modes for blunt-notched specimens in the very high cycle regime can be divided into three types: (i) surface initiation, (ii) subsurface with flat facet, and (iii) subsurface with “facet + fine granular area”. The crack initiation mechanism of blunt-notched specimens is discussed in view of the interaction of notch stress gradient distribution and heterogeneous microstructure. Furthermore, the fatigue limit model based on the theory of critical distance (TCD) was modified for the very high cycle regime, and the scatter of the fatigue property of the blunt-notched specimens were well predicted by using this model.

Aqueous zinc ion batteries are considered to be one of the most promising battery types for stationary energy storage applications. Due to their aqueous electrolyte, they are inherently safe concerning flammability and environmentally friendly. In this work, the strong influence of the particle size of manganese sesquioxide on the performance of the battery is investigated. Ball milling was used to decrease the particle diameter. The resulting powders were used as active material for the cathodes, which were assembled in coin cells as full cells together with zinc foil anodes and aqueous electrolyte. It was shown that about one third of the original particle size can nearly triple the initial capacity when charged with constant current and constant end-of-charge voltage. Additionally, smaller particles were found to be responsible for the collapse of capacity at high current densities. By means of electrochemical impedance spectroscopy, it was shown that particle size also has a large impact on the internal resistance. Initially, the internal resistance of the cells with small particles was about half that of those with big particles, but became larger during cycling. This reveals accelerated aging processes when the reactive surface of the active material is increased by smaller particles.
