Conducting fabric

Field: Materials Science (Physical Sciences)

Electrochemical characterization a b s t r a c t Polyaniline coated conducting fabrics have been obtained by chemical oxidation of aniline by potassium peroxydisulfate on polyester fabrics. Two different acids have been employed to carry out the synthesis (HCl and H2SO4), obtaining the best results of conductivity with the latter one. The conducting fabrics have been characterized chemically by means of Fourier transform infrared spectroscopy with attenuated total reflection (FTIR-ATR), energy dispersive X-Ray (EDX) and X-ray photoelectron spectroscopy (XPS). The morphology of the coatings has been observed by means of scanning electron microscopy (SEM). The conducting properties of the fabrics have been measured by means of electrochemical impedance spectroscopy (EIS). The electrochemical characterization has been carried out by means of cyclic voltammetry (CV) and scanning electrochemical microscopy (SECM). The conducting fabrics have also shown electrochromic properties, changing its color from green yellowish at!1 V to dark green at +2 V. The durability of the coating has been eval-uated by means of washing and rubbing fastness tests.! 2011 Elsevier Ltd. All rights reserved. 1.
Chelating agent differences in ferrous iron determinations

Field: Chemistry (Physical Sciences)

Abstract Experiments were conducted to test the ability of ferrous iron (Fe2+) chelating agents to discriminate between Fe2+ and ferric iron (Fe3+), to determine ranges of Fe2+ detection in reactions, to determine interactions of chelating agents with phosphorus (P) which is common in plant tissue, and to evaluate some of the complexities of methodology for Fe2+ determinations. PDTS [ferrozine; 3‐(2 pyridyl)‐5,6‐bis (4‐phenyl‐sulfonic acid)‐l,2,4‐triazine] reacted with only small amounts of Fe3+, had a fairly wide range of Fe2+ detection (0–200 μg), P did not interfere with the reaction, and methodology was relatively simple. TPTZ [2,4,6‐tripyridyl‐s‐triazine] was very specific for Fe2+, did not react with Fe3+, had a relatively narrow range of Fe2+ detection (0–40 μg), P did not interfere with the reaction, and methodology was relatively simple. BPDS [4,7‐diphenyl 1.10‐phenanthrolinedisulfonic acid] reacted with a small amount of Fe3+, had a fairly wide range of Fe2+ detection (40–200 μg), did not react with low levels of Fe2+ (<40 μg), P did not interfere with the reaction, and the methodology was relatively simple. OPh [1,10‐o‐phenanthroline] reacted extensively with Fe3+, had a wide range of Fe2+ detection (0–200 μg), P did not interfere with the reaction, and methodology was relatively simple. BDTPS [2,4‐bis(5,6‐diphenyl‐1,2,4‐triazine‐3‐yl)‐pyridinetetrasulfonic acid], BPT [4,7‐diphenyl‐1,10‐phenanthroline], and PDT [3‐(2pyridyl)‐5,6‐diphenly‐1,2,4‐triazine] were considered, but the literature indicated that P interferred with BDTPS and BPT reactions, citrate interferred with the BPT reactions, and the methodologies for PDT and BPT were relatively complex (required special separations and extractions). PDTS was the best of the chelating agents tested for Fe2+ determinations. OPh plus hydroxylamine (OPhH) was the best of the chelating agents for the determination of total Fe.
Intelligent Tunable Wave-Absorbing CNTs/VO2/ANF Composite Aerogels Based on Temperature-Driving

Field: Materials Science (Physical Sciences)

The development of new electromagnetic absorbing materials is the main strategy to address electromagnetic radiation. Once traditional electromagnetic wave-absorbing materials are prepared, it is difficult to dynamically change their electromagnetic wave-absorbing performance. Facing the complexity of the information age and the rapid development of modern radar, it is significant to develop intelligent modulation of electromagnetic wave-absorbing materials. Here, CNTs/VO2/ANF composite aerogels with dynamic frequency tunability and switchable absorption on/off were synthesized. Based on the phase change behavior of VO2, the degree of polarization and interfacial effects of multiple heterogeneous interfaces between VO2 and CNTs and aramid nanofibers (ANFs) were modulated at different temperatures. With the increase in temperature (from 25 to 200 °C), the maximum absorption frequency of the frequency tunable aerogel is modulated from 12.24 to 8.56 GHz in the X-band, and the absorption intensity remains stable. The maximum effective switching bandwidth (ΔEAB) of the wave-absorbing switchable aerogel is 3.70 GHz. This study provides insights into intelligent electromagnetic wave absorption performance and paves the way for temperature-driven application of intelligent modulation of electromagnetic absorbers.
Textual Biography: Writing the Lives of Books

Field: Arts and Humanities (Social Sciences)

Most discussions of literary property amongst biographers are concerned with practical questions, such as how to gain access to people, manuscripts, and letters, and the legal status of such activities and materials. Biographers routinely compare themselves to burglars, detectives, explorers, or authorised guests touring a stately home (even if with burglary secretly in mind). All of these metaphors assume that an analogy can be drawn between books, someone's personality or reputation, and various kinds of property — land, housing, or other artefacts — which can be owned by individuals and institutions, and are subject to a nation's laws and statutes (the laws of libel, trespass, patent, copyright, and so on). At the same time, most biographers are aware that the notion of a fixed identity 'out there', to be explored, transgressed, protected, or owned, is at best a convenient shorthand. It is certainly economical with the truth, for one of the key fascinations of biography lies in the interplay it offers between the continuity of its subject's individual body and his or her personal identity, that same individual's knowledge and experience of continual change and adaptation, and the efforts of the biographer, through research and narrative, to re-imagine and interpret this experience afresh.
Mood Disorders

Field: Psychology (Social Sciences)

Abstract Mood disorders are psychological disturbances characterized by intense emotional experiences of depression, mania, or both depression and mania. Mood disorders are remarkably diverse in their features but they share a focus on an excessive mood that colors and distorts the way the person thinks and views the world, accompanied by marked changes in movement, activity, energy, sleep, appetite, and motivation for engagement in the world. Depressive disorders are so frequent that they have been called the common cold of psychological disorders but, unlike the common cold, their consequences can be profoundly distressing, disruptive, and impairing. Included within this chapter will be current research and the prevailing theories regarding the phenomenology, etiology, and pathology of unipolar depressive disorders (e.g., major depressive disorder and dysthymia) and bipolar mood disorders (e.g., bipolar I, bipolar II, and cyclothymia).
Unsteady dynamo effects at large magnetic reynolds number

Field: Physics and Astronomy (Physical Sciences)

Abstract In this paper we show that the adjoint formulation of the Stretch-Fold-Shear (SFS) fast dynamo model has smooth eigenfunctions at zero diffusivity. We thus compute fast dynamo action with smooth fields. We note that the adjoint problem is equivalent to use of a vector potential in reversed flow. We compare this behavior with analogous results for general pulsed-flow models. Some calculations using pulsed Beltrami waves are described. Key Words: Fast dynamosBeltrami flows

Extinction-Optimized Volume Illumination

Field: Computer Science (Physical Sciences)

We present a novel method to optimize the attenuation of light for the single scattering model in direct volume rendering. A common problem of single scattering is the high dynamic range between lit and shadowed regions due to the exponential attenuation of light along a ray. Moreover, light is often attenuated too strong between a sample point and the camera, hampering the visibility of important features. Our algorithm employs an importance function to selectively illuminate important structures and make them visible from the camera. With the importance function, more light can be transmitted to the features of interest, while contextual structures cast shadows which provide visual cues for perception of depth. At the same time, more scattered light is transmitted from the sample point to the camera to improve the primary visibility of important features. We formulate a minimization problem that automatically determines the extinction along a view or shadow ray to obtain a good balance between sufficient transmittance and attenuation. In contrast to previous approaches, we do not require a computationally expensive solution of a global optimization, but instead provide a closed-form solution for each sampled extinction value along a view or shadow ray and thus achieve interactive performance.
Reduction and Null Space Algorithms for the Subspace Clustering Problem

Field: Computer Science (Physical Sciences)

This paper presents two algorithms for clustering high-dimensional data points that are drawn from a union of lower dimensional subspaces. The first algorithm is based on binary reduced row echelon form of a data matrix. It can solve the subspace segmentation problem perfectly for noise free data, however, it is not reliable for noisy cases. The second algorithm is based on Null Space representation of data. It is devised for the cases when the subspace dimensions are equal. Such cases occur in applications such as motion segmentation and face recognition. This algorithm is reliable in the presence of noise, and applied to the Hopkins 155 Dataset it generates the best results to date for motion segmentation. The recognition rates for two and three motion video sequences are 99.15% and 98.85%, respectively.
Pengukuran Dan Sosialisasi Terkait Pengetahuan Masyarakat Dalam Penanganan Infeksi Awal Influenza Melalui Media Sosial

Field: Health Professions (Health Sciences)

Recently, the world has been hit by a pandemic caused by a virus of the type of influenza that spreads very quickly, called COVID-19. It is named that cause of the disease from this type of influenza virus is relatively new and has not been widely known and began to spread at the end of 2019. Influenza itself is an acute respiratory tract infection (ARTI) caused by an influenza virus from the Orthomyxoviridae family, which can cause mild to severe symptoms. To avoid the occurrence of more severe or recurrent infections requires prevention and proper handling of the influenza disease. But in fact, there are still many Indonesian people who underestimate this and think that the flu is an ordinary disease because this disease actually can heal on its own. To reduce the spread or break the chain of transmission of the influenza virus, the community needs to adequate awareness and knowledge given. Through virtual KKN-PPMD activities, we want to learn the extent of public knowledge about how to prevent and treat early influenza infection. In this activity, an assessment will be given at the beginning and end of providing education related to knowledge for the prevention and handling of early influenza infections. The provision of virtual education was distributed through social media (Youtube, Whatsapp, Instagram, Facebook). The activity results from the category of random respondents in which the majority were women by 73%, with ages ranging from 15-35 years and status as students, it was found that a significant increase in knowledge showed that from each groups as like age group, education level, and type of work, namely 3,495 (sig. 0.062), 5.017 (sig. 0.025), and 1.140 (sig. 0.286).
Simulation of a Pulsating Air Pocket in a Sloshing Tank Using Unified Conservation Laws and HCIB Method

Field: Engineering (Physical Sciences)

The code developed using a pressure-based method for unified conservation laws of incompressible/compressible fluids is expanded to handle moving or deforming body boundaries using the hybrid Cartesian/immersed boundary method. An instantaneous pressure field is calculated from a pressure Poisson equation for the whole fluid domain, including the compressible gas region. The polytropic gas is assumed for the compressible fluid so that the energy equation is decoupled. Immersed boundary nodes are identified based on edges crossing body boundaries. The velocity vector is reconstructed at the immersed boundary node using an interpolation along the assigned local normal line. The developed code is validated by comparing the time histories of pressure and wave elevation for sloshing in a rectangular and a membrane-type tank. The validated code is applied to simulate air cushion effects in a rectangular tank under sway motion. Time variations of pressure fields are analyzed in detail as the air pocket pulsates. It is shown that the contraction and expansion of the air pocket dominate the pressure loads on the wall of the tank. The present results are in good agreement with other experimental and computational results for the amplitude and the decay of the pressure oscillations measured at the pressure gauges.

Field: Social Sciences (Social Sciences)

Food insecurity is a global phenomenon which impacts a variety of social, economic, and life-stage groups. One such group affected by food insecurity is college students, who tend to experience food insecurity at a prevalence which exceeds the average of their local communities. The impacts of food insecurity in this population are multifaceted and have implications for their college experience and beyond. Food insecurity has been observed to have negative effects on college student academic performance, physical health, and mental health. This review explores the impacts of and solutions for food insecurity in this population globally, with particular emphasis on the United States, and specifically California.
Using Theory in Social Marketing to Predict Waste Disposal Behaviour among Households in Ghana

Field: Social Sciences (Social Sciences)

The study sought to examine how a behavioral change theory (theory of planned behavior) could be used in social marketing to predict households’ waste disposal behavior in Ghana. A quantitative approach using self-administered questionnaires was used for this study. Empirical data was drawn from 343 respondents in the Greater Accra Region. Structural Equation Modelling was used to analyze the hypothesized paths/relationships. The study found that attitude was the strongest predictor of behavior, followed by subjective norm and then intention. In relation to waste disposal behavior, this paper provides evidence for issues of potential research and managerial interest. Practically, the study findings will help social marketing implementers and policy-makers to develop effective waste disposal intervention programs using variables that are applicable in our context. This study appears to be the first to systematically and quantitatively apply the Theory of Planned Behavior (TPB) in social marketing to investigate waste disposal behavior in an emerging economy context, thus providing empirical evidence for academics, practitioners and public service practises.
Bio-based senior chemical engineering laboratory course

Field: Chemical Engineering (Physical Sciences)

In the senior chemical engineering laboratory course, chemical engineering principles are applied to the evaluation and reporting of the performance of bench scale and pilot scale process equipment. Over the past two years the experiments have been revamped to reflect the emphasis on biological engineering in the workplace of many of the recent chemical engineering graduates. Such emphasis is also reflected in current ABET guidelines. The new experiments are thematic based and use the protein processing techniques that are part of the authorspsila individual collagen research programs. This thematic approach is all within the context of the fluid, heat and mass transfer content of the coursework. The key experiments that are performed include: drying, calorimetry (DSC), milling, centrifugation, dispersion, blending, vacuum systems (ovens and lyophilizers), convective heat transfer (for heating and freezing), viscometry, particle settling, microscopy, protein kinetics (crosslinking, denaturing, and modification), controlled release diffusion studies, and gel extraction. Several of the experiments are grouped as a modular approach to the manufacture of a bio-based product. As an example, artificial tissue for direct application or as a coating is produced in a process that covers several weeks and requires many different unit operations. Experimental data as well as pedagogical data is presented from the initial two years of the offering of modification of this course.
Determinants of Poor Mental Health of Medical Students in Portugal—A Nationwide Study

Field: Psychology (Social Sciences)

Medical students are a population that is vulnerable to the development of anxiety, depression, and burnout. This observational cross-sectional study sought to assess the levels of distress and identify precipitating factors in all students enrolled in a Portuguese medical school during the academic year of 2022/23. Students (n = 768) were surveyed via validated instruments to measure anxiety, depression, and burnout. Sociodemographic information was also collected through a questionnaire. The study indicated that almost half of this population had depressive symptoms. No differences were found in distress levels between medical schools, and when comparing curricular years, higher levels of distress were found in the pre-clinical years in comparison to the clinical ones. Burnout, being a woman, the existence of physical health problems, homo- and bisexual orientations, affective family problems, problems with relationships in the academic community, difficulties in academic performance, and daily organization were identified as predictors of distress. On the other hand, satisfaction with the social support received and with academic ratings were identified as protective factors. In conclusion, there is a high prevalence of distress in medical students, which is associated with personal, physical, social, economic, and academic factors. The identification of predictive factors of distress may allow for the early identification of vulnerable students and for intervention and prevention strategies to be defined.
Simulation of the ionizing radiation effects induced on an ideal NPN vertical BIMOS transistor

Field: Engineering (Physical Sciences)

This paper is related to the study of the ionizing radiation effects induced on an ideal NPN vertical BIMOS transistor. The electrical performances of the vertical BIMOS transistor have already been analysed through simulation, theoretical study and confirmed by an experimental prototype. Thus it is of interest to simulate ionizing radiation effects by introducing /spl Delta/Q/sub ox/, and /spl Delta/D/sub it/. Moreover, through electrical characterization we can separate the two types of defect, /spl Delta/Q/sub ox/, and /spl Delta/D/sub it/ to understand their different effects on device performance and support process qualification.
Issues and Prospects in Continuing Education for Skills Development of Automobile Technicians in Nigeria

Field: Social Sciences (Social Sciences)

The automobile technicians are catalytic to the industrial revolution, employment generation, human capital development, and economic growth in the automotive industry in Nigeria. There is, however, a lack of competencies among them that has generated concerns in the community of practice. The study explored challenges of skills development among automobile technicians and examined the prospects of continuing education to enhance their skills development in the automotive industry. The study adopted a qualitative research method and reviewed journals, books, news reports, and official publications to discuss the key concepts of continuing education, skills development, and mainstreaming of automobile technicians in the informal sector to the national policy framework to transform the automotive industry for human capital development and economic growth in Nigeria. The absence of continuing education in the occupational practices of automobile technicians has created skills development crises in the automotive industry and is evidenced by a shortage of skilled labour, aging demographics, the prevalence of quackery, lack of requisite work knowledge, non-availability of sustainable continuing education programmes, lack of opportunities for continuing professional development, sectoral policy disconnect with human capital development practice in the industry, and funding. The implementation of continuing education programmes for the skills development of automobile technicians can create opportunities to enhance improved competencies, transform human capital development, and engender value creation and exceptional service delivery in the automotive industry through the transformative work environment and delivery of collaborative skills development programmes. The government should mainstream and implement grassroots policies for inclusive collaboratives to certify automobile technicians through continuing educational development programmes in the automotive industry.
