EMI Shielding and Absorption of Electroconductive Textiles with PANI and PPy Conductive Polymers and Numerical Model Approach

The paper presents the results and analysis of interdisciplinary research concerning electromagnetic field shielding, conductive polymers printed on textiles and numerical simulation using the finite element method (FEM). The use of conductive, layered textiles for shielding electromagnetic interference (EMI) has been proposed. After establishing the optimal conditions for deposition of polyaniline (PANI) and polypyrrole (PPy) on polyacrylonitrile (PAN) fabric, conductive composites were made by means of reactive inkjet printing. For this purpose, polyacrylonitrile (PAN) fabrics were coated with polyaniline or polypyrrole, obtained by chemical oxidation of aniline hydrochloride and pyrrole by ammonium peroxydisulfate. The morphology of the obtained coatings was observed using a scanning electron microscope (SEM). The conductive properties (surface resistance) of the fabrics were measured using the four-wire method, and the tests of the effectiveness of electromagnetic shielding were carried out using the waveguide method in the frequency range from 2.5 to 18 GHz. The results of experimental shielding effectiveness (SE) tests and numerical simulation showed that the composites of polyacrylonitrile with polyaniline PAN/PANI and polyacrylonitrile with polypyrrole PAN/PPy achieved very good and good EMI shielding efficiency, respectively. Moreover, the obtained measurement results were verified by numerical modeling with the use of FEM–ANSYS HFFS software.
Adaptive Water Management-land Use Practice for Improving Ecosystem Services – a Hungarian Modelling Case Study

During the 20th century in the Hungarian lowlands the emphasis was put on maximizing provisioning ecosystem services (ES), which caused the weakening of regulating and other services. With the growing environmental pressures, it is crucial to apply a more adaptive landscape management. This, however, leads to territorial conflicts, as large areas with water-tolerant land cover (i.e., wetlands, meadows, riparian forests) are needed to buffer extreme hydrological events.We present some findings of the WateRisk project, a research that focused on the possible solutions of these conflicts. In a scenario-based case study, we analyze the outlined issue for the Szamos-Kraszna Interfluve, a 510 km2 lowland catchment heavily affected by excess water. Scenarios were evaluated with an integrated methodology that focuses on the water budget and the total values of ES. The efficiency of the drainage network was found to be minor/moderate as it provided only -1–5% reduction in the spatial extents of inundations, and it contributed only ~20% to the elimination of water coverage. Furthermore, comparing the present (defense-focused) and the alternative (water retention focused) scenarios, the latter turned out to provide higher monetary value for the summed individual and social benefits of ES. This underlines the need for extensive adaptive measures in both water management and landscape planning to create resilience and the ability to cope with contemporary environmental challenges.
Simulation comparison of wake mitigation control strategies for a two‐turbine case

Wind turbines arranged in a wind plant impact each other through their wakes. Wind plant control is an active research field that attempts to improve wind plant performance by coordinating control of individual turbines to take into account these turbine–wake interactions. In this paper, high-fidelity simulations of a two-turbine fully waked scenario are used to investigate several wake mitigation strategies, including modification of yaw and tilt angles of an upstream turbine to induce wake skew, as well as repositioning of the downstream turbine. The simulation results are compared through change relative to a baseline operation in terms of overall power capture and loading on the upstream and downstream turbine. Results demonstrated improved power production for all methods. Analysis of control options, including individual pitch control, shows potential to minimize the increase of, or even reduce, turbine loads.Copyright © 2014 John Wiley & Sons, Ltd.
On the Lingual Articulation in Vowel Production: Case Study from

Lingual articulation is of particular importance to understand both physiological and acoustic aspects of speech production. This paper presents a PARAFAC modeling of lingual articulation in vowel production in Ningbo Chinese. The lingual articulatory data were acquired from seven Ningbo speakers using Carstens's Eelectromagnetic Articulograph (EMA). Results show that a two-factor model best captures the tongue movement of vowel production, and the model explains about 90% of variance. The PARAFAC modeling of vowels is a speaker-independent generalization concerning the sampled tongue positions and the inferred lingual gestures. The results from Ningbo Chinese are consistent with those from English and other European languages. The fact that the extracted lingual movement mechanisms are comparable to the functional representation of tongue muscle forces from the EMG study (Maeda & Honda, 1994; Honda, 2000) suggests that the PARAFAC model of lingual articulation has physiological implications and reflexes speech motor organization for vowel articulation.
Complementary Currencies for Humanitarian Aid

The humanitarian sector has gone through a major shift toward injection of cash into vulnerable communities as its core modality. On this trajectory toward direct currency injection, something new has happened: namely the empowerment of communities to create their own local currencies, a tool known as Complementary Currency systems. This study mobilizes the concepts of endogenous regional development, import substitution and local market linkages as elaborated by Albert Hirschman and Jane Jacobs, to analyze the impact of a group of Complementary Currencies instituted by Grassroots Economics Foundation and the Red Cross in Kenya. The paper discusses humanitarian Cash and Voucher Assistance programs and compares them to a Complementary Currency system using Grassroots Economics as a case study. Transaction histories recorded on a blockchain and network visualizations show the ability of these Complementary Currencies to create diverse production capacity, dense local supply chains, and data for measuring the impact of humanitarian currency transfers. Since Complementary Currency systems prioritize both cooperation and localization, the paper argues that Complementary Currencies should become one of the tools in the Cash and Voucher Assistance toolbox.
The Six-Phase Comprehensive Project Life Cycle Model Including the Project Incubation/Feasibility Phase and the Post-Project Evaluation Phase

A holistic systems perspective of projects and programs is required today to achieve the full benefits of systems thinking 4 in project management. To achieve this perspective, the need to establish a Comprehensive Project Life Cycle definition and to promote its application on all important projects is first presented. This Comprehensive Project Life Cycle Model recognizes that there is always a Project Incubation/Feasibility Phase prior to the currently existing Project Starting Phase of most project management (PM) standards, and also recognizes that there must be an additional Post-Project Evaluation Phase after the standard Project Close-out Phase. These phases are defined and discussed for two basic types of projects: 1) delivery or commercial projects and 2) transformational projects. It is recommended that this Comprehensive Project Life Cycle Model be considered for adoption as a standard for important projects. While many PM practitioners and authorities limit the scope of ‘project management’ to the traditional start-plan-execute-closeout phases, projects begin their existence before the traditional start phase and their products or results continue to exist and must be evaluated after the projects are closed out. The authors assert that these before and after phases must be recognized as belonging within the domain of project management. Regarding the Post-Project Evaluation Phase the need to differentiate between ‘project success’ and ‘project value’ is discussed.
The effect of anxiety on foreign language academic achievement

Anxiety has commonly been regarded as one of the most significant affective obstacles in language learning achievement, and has been the subject matter of many second language researches (MacIntyre & Gregersen, 2012; Huang, 2012; Hewitt & Stefenson, 2011; Riasati, 2011; Horwitz, 2001). The primary purpose of the present study is to explore the anxiety levels of a class of students studying at the University of Dunaújváros and to investigate their attitude towards acquiring a second/foreign language. On the basis of the information gained the study is aiming at revealing some degree of correlation between students’ anxiety and their academic achievement. Responses to the Foreign Language Anxiety Scale show that the relatively high levels of anxiety among these participants are related to the worry about (1) the consequences of failing their foreign language class, (2) thinking that the others are better at languages and (3) communication with native speakers of the foreign language. However, the results on the relationship between anxiety levels and academic achievements show no significant correlation between these two variables, which leads us to the conclusion that the participants’ anxiety levels do not exceed the level which would have a negative impact on their academic results.
The effect of probiotic supplementation on systemic inflammation in dialysis patients

Background Emerging evidence suggests that intestinal dysbiosis contributes to systemic inflammation and cardiovascular diseases in dialysis patients. The purpose of this study was to evaluate the effects of probiotic supplementation on various inflammatory parameters in hemodialysis (HD) patients. Methods Twenty-two patients with maintenance HD were enrolled. These patients were treated twice a day with 2.0 ×1010 colony forming units of a combination of Bifidobacterium bifidum BGN4 and Bifidobacterium longum BORI for 3 months. The microbiome and fecal short-chain fatty acids (SCFAs) were analyzed. The percentages of CD14+ CD16+ proinflammatory monocytes and CD4+ CD25+ regulatory T-cells (Tregs) before and after probiotic supplementation were determined by flow cytometry. Serum levels of calprotectin and cytokine responses upon lipopolysaccharide (LPS) challenge were compared before and after probiotic supplementation. Results Fecal SCFAs increased significantly after probiotic supplementation. Serum levels of calprotectin and interleukin 6 upon LPS stimulation significantly decreased. The anti-inflammatory effects of probiotics were associated with a significant increase in the percentage of CD4+ CD25+ Tregs (3.5% vs. 8.6%, p < 0.05) and also with a decrease of CD14+ CD16+ proinflammatory monocytes (310/mm2 vs. 194/mm2, p < 0.05). Conclusion Probiotic supplementation reduced systemic inflammatory responses in HD patients and this effect was associated with an increase in Tregs and a decrease in proinflammatory monocytes. Hence, targeting intestinal dysbiosis might be a novel strategy for decreasing inflammation and cardiovascular risks in HD patients.
An averaged estimation of field strength into an enclosed large cavity with PCB board

In this article, two analysis methods, which are called as one is the combination of coplanar strip line analysis and Baum–Liu–Tesche (BLT) equation and the other combination of PoWer Balance (PWB) method and BLT equation, are used to predict the field strength level from the plane wave outside into an large enclosure with aperture and PCB boards inside. In realistic situations, an electrically large enclosure with an aperture has a drawback in calculating the field distribution inside the cavity precisely because of multiple reflections and resonance phenomena. Commercially available software based on the previously well‐established algorithms such as finite difference time domain (FDTD), finite element method (FEM), method of moment (MOM), and so on require much time consumption to carry out the field analysis within a limitation of accuracy, especially in the regime of high frequency. However, to overcome these resource and time‐consumption problem, PWB method based on statistical theory and BLT equation applying topological method are introduced and combined to give a reasonably good field estimation result. © 2015 Wiley Periodicals, Inc.

Effect of Head Groups in Self-Assembled Monolayer Passivation on Properties of InSnZnO Thin-Film Transistors

Self-assembled monolayers (SAMs) with three different head functional groups are prepared as passivation layers (PVLs) for amorphous InSnZnO (ITZO) thin-film transistors (TFTs). Head groups exhibit considerable modulation of surface topography and surface energy, leading to a difference in the passivation effect. This variation is attributed to the discrepancy of the binding methods determined by the head groups. Additionally, the head groups also modulate the relative direction and strength properties of dipoles at ITZO surface, which affects the surface potential and carrier density in ITZO films. As a consequence, the electric performance and stability of devices can be modulated by head groups in SAMs. These results provide a likely and low-cost method to ameliorate the capability of TFTs.
Normalized Dryness Built-up Index (NDBI) to Detect Settlement Change In Buleleng Sub-District

This research aims to find out the development of settlements that occur over the next 20 years. Monitoring the development of settlements is carried out by remote sensing methods using Landsat 7 ETM+ imagery and Landsat 8 OLI imagery. Landsat 7 ETM+ used in 2000, and Landsat 8 OLI used in 2019. The algorithm is used to identify settlement development using the Normalized Dryness Built-up Index (NDBI). This algorithm uses two bands, such as Near-infrared and shortwave infrared, to calculate. The results showed that the growth of settlements occurred very significant because, in 2000, the number of settlements amounted to 628.2 hectares and in 2019 amounted to 1891.8 hectares. The increase in settlements occurred throughout the region in the Buleleng sub-district. Therefore, it can be concluded that NDBI can be used to monitor the development of settlements and the increase in settlements occurring as much as 28 % over 20 years.
Pharmacological inhibition of Carbonic Anhydrase IX and XII to enhance targeting of acute myeloid leukaemia cells under hypoxic conditions

Acute myeloid leukaemia (AML) is an aggressive form of blood cancer that carries a dismal prognosis. Several studies suggest that the poor outcome is due to a small fraction of leukaemic cells that elude treatment and survive in specialised, oxygen (O2)‐deprived niches of the bone marrow. Although several AML drug targets such as FLT3, IDH1/2 and CD33 have been established in recent years, survival rates remain unsatisfactory, which indicates that other, yet unrecognized, mechanisms influence the ability of AML cells to escape cell death and to proliferate in hypoxic environments. Our data illustrates that Carbonic Anhydrases IX and XII (CA IX/XII) are critical for leukaemic cell survival in the O2‐deprived milieu. CA IX and XII function as transmembrane proteins that mediate intracellular pH under low O2 conditions. Because maintaining a neutral pH represents a key survival mechanism for tumour cells in O2‐deprived settings, we sought to elucidate the role of dual CA IX/XII inhibition as a novel strategy to eliminate AML cells under hypoxic conditions. Our findings demonstrate that the dual CA IX/XII inhibitor FC531 may prove to be of value as an adjunct to chemotherapy for the treatment of AML.
In Situ Printing and Functionalization of Hybrid Polymer-Ceramic Composites Using a Commercial 3D Printer and Dielectrophoresis—A Novel Conceptual Design

Three-dimensional printing-based additive manufacturing has emerged as a new frontier in materials science, with applications in the production of functionalized polymeric-based hybrid composites for various applications. In this work, a novel conceptual design was conceived in which an AC electric field was integrated into a commercial 3D printer (-based fused filament fabrication (FFF) working principle) to in situ manufacture hybrid composites having aligned ceramic filler particles. For this work, the thermoplastic poly lactic acid (PLA) was used as a polymer matrix while 10 vol% KNLN (K0.485Na0.485Li0.03NbO3) ceramic particles were chosen as a filler material. The degree of alignment of the ceramic powders depended upon print speed, printing temperature and distance between electrodes. At 210 °C and a 1 kV/mm applied electric field, printed samples showed nearly complete alignment of ceramic particles in the PLA matrix. This research shows that incorporating electric field sources into 3D printing processes would result in in situ ceramic particle alignment while preserving the other benefits of 3D printing.
NEW OPTICS FOR THE SOLEIL STORAGE RING

SOLEIL, the French 2.75 GeV synchrotron light source is delivering photons to 24 beamlines and is presently equipped with 24 insertion devices (ID) including a high field and small gap in-vacuum wiggler [1]. This paper presents the continuous work performed to reduce the strong non-linear effects of several IDs. On one side, the ID defaults have been accurately identified using on-beam measurements, and magnetic correction developments are going on and on the other side, a new optics has been optimised in terms of beta-functions (at the ID location) and non-linear dynamics in order to improve the injection efficiency and the beam lifetime in the presence of IDs. In parallel, an extensive experimental optimization has been performed to prepare the operation with an additional quadrupole triplet that provides double low vertical beta functions in one long straight section that will accommodate two canted in-vacuum undulators [2]. The paper presents also the dedicated "low-" optics that has been optimised for short bunch production.
Wide area voltage protection

Two very promising wide-area voltage protection (V-WAP) solutions, able to face stability and security problems in the transmission grid, are presented. Both require real-time effective risk indicators whose timely computing is a crucial issue. The first method makes use of a voltage instability index based on real-time computing of the Thevenin equivalent circuit seen by a given high voltage (HV) bus. The innovating algorithm utilised for the real-time adaptive identification of the Thevenin voltage and impedance equivalent values requires local phasor measurements at fast sampling rate. The unique ability of the second method is mainly because of an effective coordination with a supposed operating wide-area voltage regulation (V-WAR) modern system where the secondary and tertiary voltage regulations (SVR and TVR, respectively) operate according to their hierarchies. Evidence for the feasibility and simplicity in defining and developing an effective V-WAP solution once reliable real-time risk indicators are available is provided. The feasibility of the first method comes from the high computing speed of the local risk indicator at each area bus where a phasor measurement unit (PMU) is installed. The main simplification of the second method comes from the already existing and appropriate subdivision of the network into areas provided by the operating SVR, the same areas as those of the protection scheme intervention. From this starting point, a voltage stability index is proposed operating the area load shedding (LS) according to a simple and incontrovertible logic based on the real-time area control effort. Dynamic simulation results on the North Italy power system show the proposed protection scheme's effectiveness and ability to achieve the continuity and stability of the controlled power system in front of a ramping load increase, by also containing the LS amount.
How Language Learners Can Benefit From Corpora, Or Not

This paper discusses how learners can come into contact with corpora and the different ways in which corpora can be useful to them. There are three main ways in which this can be done, and rather than competing against each other, I see these three different gateways to corpora as being complementary. I also wish to show that, as with any kind of materials and activities developed under the aegis of a particular methodology and approach to learning, some uses of corpora in the classroom can be very effective, while others may not work at all.
A two-dimensional finite-element analysis of reverberation chambers

A two-dimensional (2-D) analysis of reverberation chambers is performed at cutoff. The structure considered is lossless and corresponds to an infinite quality factor (Q) chamber. The concept of frequency stirring is used to generate field data for a discrete set of modes and the resulting statistics are analyzed. The field statistics are examined for TE and TM modes. This analysis yields statistics similar to the expected reverberation chamber statistics for the fields. Mechanical stirring is also examined and a connection to the peak-frequency deviation is presented.
Building Value through Sustainable Project Management Offices

Organizations’ attempts to implement and gain value from investments in project management have resulted in the rapid growth and, in some cases, demise of project management offices (PMOs). The recent research literature on PMOs provides an ambiguous picture of the value case for PMOs and suggests the tenuous nature of their current position in many organizations. In studying project management implementations for the Value of Project Management project, we chose to use three detailed cases and comparisons with the remaining 62 organizations in the value project to study how PMOs are connected to value realization for organizations investing in project management. Specifically, we sought to understand how PMOs deliver sustained value to organizations. Using the theories of Jim Collins (Collins, 2001; Collins & Porras, 1994) as an interpretive framework, we explore these cases to understand how to create and sustain project management value through investment in PMOs.
Simulation Design of Transmission Module of Coal Mine Roadway Advanced Detector

An advanced detector based on the dual frequency IP method was designed to solve the speed unmatched problem between the detection and excavation. The detector consists of the transmission module and the receiving module. This paper designed the circuit of the transmission module with the Proteus software and completed the control program with the Keil software. Through the co-simulation of the circuit and the control program, the transmission waveforms designed were obtained and the system proved available, which laid the foundation for the development of the transmission module of the detector.
