A High-Lift Optimization Methodology for the Design of Leading and Trailing Edges on Morphing Wings

Morphing offers an attractive alternative compared to conventional hinged, multi-element high lift devices. In the present work, morphed shapes of a NACA 64A010 airfoil are optimized for maximum lift characteristics. Deformed shapes of the leading and trailing edge are represented through Bezier curves derived from locally defined control points. The optimization process employs the fast Foil2w in-house viscous-inviscid interaction solver for the calculation of aerodynamic characteristics. Transitional flow results indicate that combined leading and trailing edge morphing may increase maximum lift in the order of 100%. A 60–80% increase is achieved when morphing is applied to leading edge only—the so-called droop nose—while a 45% increase is obtained with trailing edge morphing. Out of the stochastic optimization algorithms tested, the Genetic Algorithm, the Evolution Strategies, and the Particle Swarm Optimizer, the latter performs best. It produces the designs of maximum lift increase with the lowest computational cost. For the optimum morphed designs, verification simulations using the high fidelity MaPFlow CFD solver ensure that the high lift requirements set by the optimization process are met. Although the deformed droop nose increases drag, the aerodynamic performance is improved ensuring the overall effectiveness of the airfoil design during take-off and landing.
Synthesis of a Fe3O4 Nanosphere@Mg–Al Layered-Double-Hydroxide Hybrid and Application in the Fabrication of Multifunctional Epoxy Nanocomposites

Layered double hydroxide (LDH) is regarded as a prominent flame-retardant nanoadditive for polymers. However, the flame-retardant efficiency of a LDH depends strongly on its dispersion state and composition. Usually, modification or functionalization of a LDH is crucial to obtaining high-performance polymer nanocomposites. In order to develop multifunctional epoxy nanocomposites, in this study a LDH was first modified by biobased flame-retardant species, phytic acid (Ph) and (hydroxypropyl)sulfobutyl-β-cyclodextrin sodium (CDBS), and subsequently decorated by Fe3O4 nanoparticles to obtain a Fe3O4 nanosphere@LDH hybrid. Results obtained from size distribution and transmission electron microscopy revealed that the Fe3O4 nanoparticles with an average size of 8 nm were well decorated on the LDH platelet. The Fe3O4-decorated LDH hybrids facilitated their dispersion within an epoxy matrix, as indicated in X-ray diffraction. The incorporation of an as-prepared Fe3O4@Ph-CDBS-LDH hybrid into epoxy resin (EP) not o.
Developing a Business Case for a Renewable Energy Community in a Public Housing Settlement in Greece—The Case of a Student Housing and Its Challenges, Prospects and Barriers

Democritus University of Thrace (DUTh) has formed, under the European Project Renaissance (Renewable Integration & Sustainability in Energy Communities, HORIZON 2020, GA 824342), a virtual Renewable Energy Community (REC) in Greece located nearby Kimmeria at the northeast of the city of Xanthi, at the North-eastern Greece. The REC formed is the first energy community designed in a public housing settlement in Greece and its members are: (a) the Democritus University of Thrace, (b) the Municipality of Xanthi and (c) a local industry. DUTh’s main objective is to explore, leverage and mobilize stakeholders to apply schemes for a social group of end users (i.e., students from low-income families) in order to participate in the operation and management of a local renewable energy community, gaining also non-financial benefits. This paper presents the business case scenario and the market players evolving at an Energy Community which includes a public establishment of student residences in Greece.
Dynamics of Soil Nutrients, Microbial Community Structure, Enzymatic Activity, and Their Relationships along a Chronosequence of Pinus massoniana Plantations

Pinus massoniana is the major afforestation and vegetation restoration tree in southern China, and it plays an important role in the sustainable development of plantations. However, long-term single planting of P. massoniana has resulted in the decline of soil quality and forest productivity, and a soil fertility assessment is urgently needed. We selected P. massoniana plantations of four age stages for plot investigation and sampling to determine the soil physicochemical properties, microbial diversity and composition, and enzyme activities at different soil depths. The results showed that soil total phosphorus (TP) and available phosphorus (AP) decreased with the increase of age, especially low C/N ratio and high C/P and N/P ratio in the 30-year and 36-year stands, leading to P limitation. Meanwhile, the bacterial Shannon index also decreased with the increase of age and was positively correlated with AP, NO3−-N, and pH. However, the fungal Shannon index decreased first and then increased with the increase of age; soil acid phosphatase (S-ACP) and urease activities showed a similar trend. Correlation analysis demonstrated that the increase of total organic carbon (TOC) and total nitrogen (TN) promoted the increase of fungal Shannon index, which was beneficial to the secretion of more enzymes. We found that soil physicochemical properties, microbial diversity, and enzyme activity decreased simultaneously when soil depths increased. Moreover, Acidobacteria and Basidiomycota were the most abundant bacterial and fungal communities, respectively, followed by Proteobacteria and Actinobacteria for bacteria and Ascomycota for fungi, and these microbial taxa were significantly affected by soil water content (SWC), TOC, AP, and C/P. In conclusion, this work reveals the potential correlation among soil physicochemical properties, microbial diversity and composition, and enzyme activities, and revealed potential correlations among them which will help to improve understanding of soil conditions and provide a reference for rational management of soil resources.
Adopting a socio-technical perspective to rethink the use of ICT in VNFIL

Purpose This paper aims to draw on a socio-technical perspective to explore how information and communication technology (ICT) supports the validation of non-formal and informal learning (VNFIL) in specific practices and arrangements. Design/methodology/approach The authors use qualitative content analysis to analyse 43 country reports of the “European inventory on validation” published by the European Centre for the Development of Vocational Training (Cedefop) in 2019. Findings This study conceptualises ICT supported VNFIL practices and arrangements from a socio-technical perspective. Given this, the paper finds that ICT is used mainly to provide information on validation practices and arrangements, store qualification registers online and identify and document learning outcomes. The use of ICT to assess and certify learning outcomes remains limited. Originality/value VNFIL is very rarely seen in a technical context. This paper contributes to a theoretical perspective and highlights the mutual interdependence of social and technical components. Furthermore, this study provides an overview of inasmuch ICT is currently used to support VNFIL practices and arrangements. Based on the results, validation researchers and practitioners can get inspiration on how to develop ICT supported VNFIL practices and arrangements further.
Uropathogens and antimicrobial susceptibility profiles of asymptomatic bacteriuria among pregnant women receiving antenatal care in traditional birth attendants homes in Ikono, Akwa- Ibom State, Nigeria

Background: Asymptomatic bacteriuria (ASB) in pregnancy is associated with adverse maternal and obstetric outcomes if untreated. The aim of this study was to determine the prevalence and susceptibility profile of ASB among pregnant women attending antenatal clinics in traditional birth attendant homes in Ikono, Akwa-Ibom State.Methods: The study was a cross sectional survey using 350 pregnant women with ASB. Mid-stream clean catch urine samples were collected from the women using sterile containers. The urine samples were cultured, bacterial colonies were identified and antibiotic sensitivity was done. Data was analyzed using SPSS version 20.0 and significant was set at ≤0.05. Results: The overall prevalence was 33.4% using 350 asymptomatic pregnant women. The mean age was 26.21±3.6 years and aged 27-32 have the highest prevalence (13.4) of ASB. 55.1% attained primary school, while 33.4% had informal education, monoparous (54%), 3rd trimester was 44.6% with 15.8% positive cases. Multigravidae was 71.1% with 19.4% positive cases. There was significant association of age, education, parity, occupation, monthly income, etc with ASB. The most common isolates were Escherichia coli (29.9%), then Klebsiella pneumonia (19.7%). Pseudomonas aeruginosa was susceptible to gentamicin (92%), Ciprofloxacin (83%) imipenam (83%) and azetronam (75%), while Staphylococcus saprophyticus was susceptible to imipenam (90%), then gentamicin at 80%. Multi-drug resistant were widespread in most of the isolates.Conclusions: Multi-drug resistant were observed in most of the isolates. Continuous and collaborative surveillance of ASB and antimicrobial resistance pattern are essential to reduce the consequence of asymptomatic bacteriuria in pregnant women.
What Is the Experience of Companies in Accounting for Impairment of Receivables?

Account receivables constitute a significant portion of current assets, and the issue of receivables management is studied from many aspects and in many different contexts and levels. The purpose of this paper is to analyse the use of the prudence principle in the account’s receivables area in Czech companies. This research paper aims to evaluate the view of enterprises whether they are willing to make impairment of receivables, what types of impairment they prefer, and how they assess the impairment of receivables. The research was done through a questionnaire survey. We received a total of 185 completed questionnaires. The research was done in 2019 in enterprises from the Czech Republic. Our results show that the enterprises make the impairment of receivables regardless of their sector. The impairment of receivables is more preferred in the medium-sized and large enterprises. The medium sized and large enterprises prefer a combination of tax and non-tax impairment of receivables. At the same time, the medium-sized and large enterprises more appreciate the impairment of receivables as a percentage of the value of particular receivable.
Improving source code suggestion with code embedding and enhanced convolutional long short-term memory

Source code suggestion is the utmost helpful feature in the integrated development environments that helps to quicken software development by suggesting the next possible source code tokens. The source code contains useful semantic information but is ignored or not utilised to its full potential by existing approaches. To improve the performance of source code suggestion, the authors propose a deep semantic net (DeepSN) that makes use of semantic information of the source code. First, DeepSN uses an enhanced hierarchical convolutional neural network combined with code ‐ embedding to automatically extract the top ‐ notch features of the source code and to learn useful semantic information. Next, the source code's long and short ‐ term context dependencies are captured by using long short ‐ term memory. We extensively evaluated the proposed approach with three baselines on ten real ‐ world projects and the results are suggesting that the proposed approach surpasses state ‐ of ‐ the ‐ art approaches. On average, DeepSN achieves 7.6% higher accuracy than the best baseline.
Chemiluminescence-based quantification of the colonization rates of Lotus japonicus roots by arbuscular mycorrhizal fungi

ABSTRACT Simple evaluation of the levels of root colonization by arbuscular mycorrhizal (AM) fungi is challenging for conventional histochemical staining because most roots show an endogenous background signal. Herein, we report a chemiluminescence-based novel method for the quantification of the relative colonization rates of AM fungi. Lotus japonicus seedlings were grown in two types of soils with different inoculum potential [i.e., the former vegetation was maize (host) or buckwheat (non-host)]. Indigenous AM fungi colonizing roots were labelled with wheat germ agglutinin-conjugated horseradish peroxidase (WGA-HRP), which specifically targets the N-acetylglucosamine polymers of fungal cell walls. After the roots were removed from the soil and rinsed with water, all procedures were conducted in 24-well plates. AM fungi were detected by chemiluminescence in the presence of enhanced chemiluminescence (ECL) reagents, and the signal strengths were measured by image analyses. Post-staining of AM fungal structures in the presence of 3,3ʹ-diaminobenzidine (DAB) and H2O2 (DAB staining) revealed that even small colonization events (e.g., hyphopodia) could be detected, whereas the background signals observed in DAB staining were eliminated in the chemiluminescence method. Chemiluminescence thus provides both high sensitivity and high specificity. The chemiluminescence-based colonization levels of roots grown in maize soil were significantly higher than those of roots grown in buckwheat soil, demonstrating the feasibility for high-throughput quantification of the relative colonization rates of L. japonicus seedlings by AM fungi.

The reflective journey: A practitioner’s guide to the low arousal approach

All behaviours occur within a relational and circumstantial context (Milton, Mills, and Jones 2016), and from time to time everyone behaves in ways that are difficult to understand and respond to. This book is described as ‘an honest framework for supporting people’ (9) to be used as a guide by anyone working with or caring for people who can become distressed and overwhelmed. Andrew McDonnell tells us that he named the book The Reflective Journey because it is ‘so important to be aware of our own behaviour in order to truly support people in crisis’ (9). In the 24 years I have been working as a researcher alongside people with learning disabilities and/or autism, I have heard many tropes about ‘challenging behaviour’, as well as individualising ways of referring to people and their ‘management’. I know that ‘challenging behaviour’ can be reduced even eliminated by recognising the contextual requirements of the person and making accommodations for them, so I welcome the principles featured in this book. McDonnell describes his approach as ‘eclectic’ (11), combining parts of many different models and strategies. The book offers practical advice about how to build alliances and good relationships with people we support, peppered with examples and case studies throughout, that are real-life experiences of McDonnell and his colleagues. Chapters have exercises and activities to appeal to different learning styles, and the end of each chapter features key learning questions for reflection. Chapter 1 ‘Understanding distressed behaviours’ asks us to look within and consider our own behaviours, demonstrating how we struggle to explain our actions on a day-to-day basis (especially if we are stressed), and therefore ‘[u]nderstanding the behaviour of someone you are supporting can also be very confusing’ (11). McDonnell asks us to think about the way we characterise and stereotype people – for example describing a person as manipulative will only provide a negative view of the person and individualise or decontextualise the issue at hand. What I really like is that the titles of chapters such as ‘Coping with anger’ really mean coping with our own anger in ways to improve how we work with people, reflecting back on our own behaviour and responses. This is so important when you consider examples of the escalation of violence and provocation that we have seen in the recent exposés of residential units. One of the striking and important questions McDonnell asks here is ‘do all behaviours need to be changed? ’
Exploring the Association and Dissociation Between Lectures and Practicums in the Process of Learning Experience in Psychiatric and Mental Health Nursing Education: a Qualitative Study in Japan

Objective: This study aimed to clarify the process of students’ experience of learning to identify association and dissociation between lectures and practicums in psychiatric and mental health nursing (PMHN) education at a university.Methods: An interview survey of 21 students from a regional national university in Japan was conducted, and the interview data were analyzed with a modified grounded theory approach.Results: The analysis identified 12 categories and 32 concepts regarding the process of learning experience in PMHN among university nursing students. Through lectures, the students accomplished “self-developmental knowledge retention” or “acquisition of superficial knowledge about PMHN” toward “formation of learning attitude based on life experience. ” The outcomes of lectures significantly affected practicums; the former possibly resulted in “non-discovery of significance of practicums;” however, the latter possibly approached “developmental self-learning. ”Discussion: The association between students’ interests based on life experience and contents of lectures affected practicums, and the lecture design readily imaginable from students’ experience was desirable. Practicums must be built on teaching strategies that make students aware of the particularity of communication.
A cross-sectional study on resilience, depression, anxiety, and stress among exam going students

Background: Adolescent age is a stage of several types of changes that affect all the domains such as physical, psychological, and social. At this age, every individual has to face several types of psycho-social stressors including academic pressure and examination stresses. The present study was planned to find two objectives; (i) to assess and compare the level of resilience and the prevalence of psychiatric distress between male and female exam going adolescents, and (ii) to assess the correlation between resilience and psychiatric distress. Material and Methods: It was based on a cross-sectional research design. A total of 100 respondents fulfilling inclusion and exclusion criteria were randomly selected from some selected schools in Varanasi district. All the selected respondents were interviewed using a semi-structured questionnaire including socio-demographic proforma, DASS-21, and Brief Resilience Scale. Results: Out of a total of 100 respondents 63 were male and the rests were female. The gender of the respondents was found significantly associated (p
Benchmarking Unmanned Aerial Systems-Assisted Inspection of Steel Bridges for Fatigue Cracks

Inspection agencies have been increasingly implementing unmanned aerial systems (UAS) for bridge inspections. Currently, UAS are typically used for long-range monitoring and surveillance tasks, but bridge managers are hopeful that they may be utilized for detailed inspection, such as condition assessments and the inspection of fracture critical members (FCMs) in the near future. As an assistive tool for visual inspections, the accuracy of UAS-assisted inspections is unknown. This study investigates the relationship between the characteristics of the individual inspectors and a set of performance metrics associated with UAS-assisted FCM inspections. Four bridge inspectors used a UAS to inspect a series of full-sized bridge specimens with known fatigue cracks. The inspection videos were later shared with 19 bridge inspectors for a desk review. The performance of each inspector was evaluated and compared with the results from 30 hands-on inspections of the same specimens. The results showed that an inspector’s past experience with UAS, licensure, and academic degree could have a significant influence on one or more of the three defined performance metrics. The comparison between the results of the UAS-assisted inspections and the hands-on inspections revealed that crack detection was comparable. However, the hands-on inspections were more accurate.
Development of a Parent-Reported Outcome Measure for Febrile Infants ≤60 Days Old

Supplemental digital content is available in the text. Objective We aimed to develop a parent-reported outcome measure for febrile infants 60 days or younger evaluated in the emergency department. Methods We conducted a 3-part study: (1) individual, semistructured interviews with parents of febrile infants 60 days or younger to generate potential items for the measure; (2) expert review with pediatric emergency medicine physicians and member checking with parents, who rated each item's clarity and relevance using 4-point scales; and (3) cognitive interviews with a new sample of parents, who gave feedback and rated the measure's ease of use on a 4-point scale. The measure was iteratively revised during each part of the development process. Results In part 1, we interviewed 24 parents of 21 infants. Interviews revealed several themes: parents' experiences with medical care, communication, and decision making; parents' emotions, particularly worry, fear, and stress; the infant's outcomes valued by parents; and the impact of the infant's illness on the family. From these themes, we identified 22 potential items for inclusion in the measure. In part 2, 10 items were revised for clarity based on feedback from physicians and parents, primarily under the domains of parents' emotions and the infant's outcomes. In part 3, we further revised the measure for clarity and added an item. The final measure included 23 items and was rated as excellent in its ease of use. Conclusions The 23-item parent-reported outcome measure includes the experiences and outcomes important to parents. Further studies are needed to evaluate the measure's psychometric properties.
