EFFECTS OF DC-BIAS CONDITIONS ON LOW-LOSS THIN FILM MICROSTRIP LINE

This paper presents the microwave characteristics of thin fllm microstrip line (TFML) under dc-bias conditions. The proposed TFML with 20"m thick polyimide layer is used as a thin dielectric supporter on low-resistivity silicon (LRS) substrate. Measured frequency-dependent microwave characteristics and equivalent lumped elements are evaluated for the dc-biased TFML over 1{50GHz. This work presents acceptable attenuation of 0.561, 0.563 and 0.565dB/mm at 50GHz with dc-bias conditions, showing that the TFML can be used for high frequency interconnects for any 3D-based microwave devices and monolithic microwave integrated circuits (MMICs).

The Other Great Migration: Southern Whites and the New Right

This paper shows how the migration of millions of Southern whites in the 20th century shaped the cultural and political landscape across America. Racially and religiously conservative, Southern white migrants created new electoral possibilities for a broad-based coalition with economic conservatives. With their considerable geographic scope, these migrants hastened partisan realignment and helped to catalyze and bolster a New Right movement with national influence over the long run. More than just augmenting the conservative voter base outside the South, they influenced non-Southerners by building evangelical churches, diffusing right-wing media, and mixing through intermarriage and residential integration. Tracking non-Southern households, we show that exposure to Southern white neighbors increased adoption of conservative religious norms. Overall, our findings suggest that this mass migration blurred the North–South cultural divide and reshaped the geography of conservatism in the U.S.
A Second Chance at Success? Effects of College Grade Forgiveness Policies on Student Outcomes

The increased popularity of college grade forgiveness policies, allowing students to substitute the new for the previous grades for repeated classes in their GPA calculations, is controversial yet under-studied. Using students’ transcript data from a four-year public institution that abolished and reintroduced grade forgiveness, we find that, grade forgiveness increases the probability of repeating by 68%. The policy benefits the students by incentivizing them to take more STEM courses and graduate with STEM degrees. We show that the concerns about students’ slacking-off when grades can be forgiven is trivial. However, the policy increases time-to-graduation and widening the existing gaps between demographic groups.
Leveraging Big Data for the Development of Transport Sustainability Indicators

Abstract While increasing transportation sustainability is an ongoing effort, measuring the results of these efforts is not a trivial task. Not only is indicator selection challenging, but efforts made to design useful indicators are often hampered by the presence of erroneous or incomplete data. Nevertheless, in this era of Big Data, the significant penetration of new technologies such as smartphones and smart infrastructure could hold the key to developing more relevant and comprehensive indicators. Here, we recall commonly used indicators and discuss the limitations of the data upon which they are built. We then describe several new technologies that hold promise for collection of more pertinent and accurate data sets for indicator development. Finally, we illustrate potential benefits and concerns of these approaches via discussion of possible indicator development from a one-day GPS trace. While the first and obvious application of new technologies will be to improve much needed accuracy, successfully combining different sources together could hold much potential from model calibration to real-time operations.

O teletrabalho na pandemia da covid-19: uma nova armadilha do capital?

Resumo Este artigo tem por escopo discutir o fenômeno do teletrabalho, que foi impulsionado em razão do contexto da pandemia do Covid-19 em 2020. Destaca-se a nova narrativa do capital, que, ao tempo que exalta seus benefícios, tende a ocultar os riscos, bem como as possibilidades de reformulação dos ganhos empresariais na exploração do trabalho humano. Para tanto, revisa-se o novo cenário do trabalho, a partir do contexto da denominada “modernização” das relações laborais, considerando os processos de intensificação das jornadas, de apropriação do espaço privado da residência dos trabalhadores, de compatibilização entre trabalho produtivo e reprodutivo, sobretudo por mulheres, de isolamento em relação aos coletivos de trabalho e suas articulações políticas, bem como de sofrimento e adoecimento psíquico. A partir de bibliografia pertinente e da análise de dados secundários sobre o teletrabalho na atualidade, é problematizada a regulação incidente sobre esses trabalhadores como elemento conformador do fenômeno.
FDTD analysis with modified matrix pencil method for the UC‐EBG low‐pass filters

In this paper, a low‐pass filter (LPF) with a uniplanar compact electromagnetic band‐gap (UC‐EBG) structure in the ground plane is investigated. The finite‐difference time‐domain (FDTD) method combined with the modified matrix pencil (MMP) method is applied to analyze this complicated structure. A short segment of an FDTD record is used to train the MMP predictor, and an accurate future realization can be obtained. The numerical simulation for low‐pass filters with UC‐EBG demonstrates that the efficiency of the FDTD method can be improved by up to 70%. © 2004 Wiley Periodicals, Inc.

ITO/Poly-3-Methylaniline/Au Electrode for Electrochemical Water Splitting and Dye Removal

Application of aniline derivative semiconductor nanopolymer and its Au composite for H2 generation and dye removal were investigated. Electrochemical polymerization of poly-3-methylaniline (P3MA) on ITO glass was carried out for acid medium. Au nanoparticles with crystal sizes of 15 and 30 nm were sputter coated on the surface. Chemical structure of the polymer and its composite was characterized using FTIR, XRD, 1HNMR, SEM, and UV-Vis. All function groups were confirmed using FTIR analyses. XRD confirmed the formation of nanopolymer with a crystal size of ~15 nm. SEM confirmed the formation of smooth lamellar surface feature with a <20 nm nanoporous structure. Porosity and particle sizes increases with Au coating, confirmed using the modeling Image J program. Optical analysis also demonstrated that the strength of P3MA absorption peaks increases with rising Au coating time, in which the bandgap values changed from 1.64 to 1.63 eV for 15 and 30 nm Au, respectively. The photoelectrode ITO/PMT/30 nm Au was applied for H2 generation and dye removal. The current density (Jph) values were -0.3 and -1.6 mA.cm-2 in the absence and presence of the Congo red dye, respectively. The incident photon-to-current conversion efficiency (IPCE%) for the electrode was 2.3 at 390 nm. The activation energy (Ea) was 31.49 KJ mol-1. The enthalpy (∆H*) and entropy (∆S*) values were 114.49 and 160.46 JK-1 mol-1, respectively. A simple mechanism for the H2 generation and dye removal is mentioned
System Architecture-based Design Methodology for Monitoring the Ground-based Augmentation System: Category I - Integrity Risk

This paper has described a method to accomplish the Ground-Based Augmentation System signal-in-space integrity risk monitoring for a ground station specified by ICAO, Annex 10, Vol.1 and RTCA DO-245-A, wich is a mandatory requirement to meet the certification aspects for a Ground-Based Augmentation System station. The proposed methodology was based on the Risk Tree Analysis technique, which is an optional way to design and develop an engineering solution named as integrity risk monitor that assures the integrity risk requirement for standard system architecture. The achieved results concern the qualitative and quantitative aspects of solution, which are met throught the system architecture and the system safety assessment process, in special by risk assessment concepts. Finally, the integrity risk monitor is an optional architectural solution (a practical way) that has demonstrated a satisfactory result to meet the certification basis of the Brazilian Aeronautical Authorities.
Cognitive maps for expert analysis of interrelations between the risk factors and their role in fire safety evaluation

DEMATEL. Рассмататриваемый подход позволяет подробно проанализировать важность отношений причина-последствие между сравниваемыми факторами. This paper presents and discusses the application of original qualitative and quantitative techniques for evaluating interrelations between factors identified as a priori and determining safety levels for building users in case of a fire, A recurrent numerical process, typical for cognitive map application, is normally used in such an evaluation. The authors suggest an alternative to the classic algorithm, by harnessing the DEMATEL method. The discussed approach appears easier to cope with and allows for a specific analysis of cause and effect relations between factors under consideration. The starting point for this approach is expert opinion applied on a multi-level evaluation scale. The algorithm can be easily adapted to examine uncertain or incomplete information e.g. application of fuzzy numbers [8] [9]. The cognitive process is represented by an impact-relations-map, whose vertices represent comparable factors and arcs reflect direct relationships between factors. Such relationships need not be one directional, they can mirror potential feedback to be incorporated in the analysis. The final evaluation sums up direct influences and the more difficult emerging indirect influences. For easier interpretation of data it is suggested that a threshold value is determined to limit superfluous information and therefore exclude factors with relationships not considered sufficiently intensive to afford clear and unequivocal deductions. The proposed maps are represented mathematically by relative matrices of direct, indirect and total influence. Moreover it is also possible to establish the net total matrix. The idea proposed by the authors is illustrated in this paper with the aid of a simple numerical example, dealing with a single expert opinion, in which the assumed influence structure between considered factors does not include feedback. Furthermore, only one deterministic data set is applied to express levels of direct influence. More advanced and complex examples are presented and discussed by the authors in other papers. Interested readers will find relevant details in the bibliography.
UNBEARABLE TRAUMA AND IRREPARABLE DAMAGE: MATERNAL DEATH BY SUICIDE RAISES SERIOUS PERPLEXITIES

INTRODUCTION: Maternal death by suicide raises serious perplexities. The ICD-10 classifies maternal suicide as an indirect form of maternal death. Due to this current misclassification, a classificatory consensus of maternal suicide as a direct form of maternal death is urgent. OBJECTIVE: Analyze the psychological that permeate the phenomenon of maternal suicide, to define the profile of mothers in the postpartum period and pregnant women who commit suicide, with the purpose of elucidating ways of preventing maternal suicide. METHOD: A systematic review was made following the PRISMA protocol (Preferred Reporting Items for Systematic Reviews and Meta-Analysis). RESULTS: Twenty-one studies reported the urgent need to implement interventions in order to prevent or reduce mental health problems caused by mothers and pregnant women who commit suicide. Twenty studies demonstrate the need for interventions to organizational adjustments, especially related to the emotional conflicts involved suicide and maternity. CONCLUSION: Maternal suicide is mainly caused by severe psychiatric disorders, however, higher suicide rates are seen due to psychosocial factors, such as poor familial support and domestic violence, illegal substance abuse and alcoholism, history of sexual or physical violence, racial oppression, economic instability, unwanted pregnancy, difficulty in accessing intentional abortion, and trauma related to past maternity experiences.
Micromachined silicon accelerometer with fiber optic interrogation

Silicon micromechanics technology has formed the basis of a range of compact and reliable sensors, measuring variables such as pressure, force and acceleration. Most micromechanical sensors require some form of electrical read-out. Therefore, these sensors are classified as electrically active. Electrically passive sensors also have many applications, and the best examples of such sensors are those based on fiber optic technology. In this paper, we describe a sensor which combines the advantages of both silicon micromechanics and fiber optics. Specifically, an accelerometer has been fabricated, and initial results on the performance of this device are presented.
Anti-windup schemes for uncertain nonlinear systems

Several processes are nonlinear and operate under input constraints. Their effective control requires model-based techniques whose performance is often affected by modelling uncertainties. The paper addresses the control of single-input single-output nonlinear systems with input constraints in the presence of modelling errors. A nonlinear internal model control based on input output linearisation is designed, and an internal model control with antiwindup which removes the nonlinear mismatch due to input constraints is given. An adaptive internal model control with anti-windup to account for parameter uncertainty and an augmented internal model control with anti-windup to attenuate the effect of modelling errors, are proposed and analysed theoretically. Simulation results on temperature control of a continuous stirred tank reactor demonstrate the benefits of the proposed anti-windup schemes.
Purification trials of Tamanu (Calophyllum inophyllum L.) oil

Tamanu (Calophyllum inophyllum L.) oil is a non-food oil used in traditional medicine, and with potential applications in the pharmaceutical and cosmetic industry. However, this oil, obtained by pressing the nuts, is being used as crude oil, in spite of a variable but large amount of non-lipids (called resin) being entrained. Although these should not be seen as impurities owing to their known bioactivity in many fields, not only they are responsible for the poisonous nature impeding human consumption in addition to bad smell, but they contribute to the poor oil quality, especially low stability and associated short shelf life. The present study aimed at purifying a crude tamanu oil sample through a combination of simple steps: deresination with ethanol, degumming using hot water, neutralization (KOH), bleaching with activated carbon, and deodorization. Ethanol 96% was more efficient for deresinating, compared to methanol, resulting in the extraction of 44–46% w/w of resin within 10 min (temperature 40 °C; oil:ethanol 1:1.5 w/v). Oil quality was checked in the industrial crude sample and in the fully refined product. The applied process strongly improved the color from dark brown to light golden yellow, decreased the acid value (62 down to 0.11 mgKOH/g of oil), and the viscosity (181 to 130 mPa.s). The saponification value was lowered from 206 to 180 mgKOH/g oil. The peroxide value was only slightly lowered from 85 to 55 mgO2/kg oil, thus pointing out the peculiar chemical nature of tamanu oil. Improving this important quality parameter would require additional research work, together with fine-tuned optimization of experimental conditions for a panel of crude oil samples; this was out of the scope of present work. This preliminary study shows that refining steps widely applied at industrial scale could help improving the quality of tamanu oil – an underused natural feedstock – for enhanced application in health and cosmetic fields.
Bifurcation behavior of the buck converter

The DC-DC buck power converter, a widely used chopper circuit, exhibits subharmonics and chaos if current feedback is used. This paper investigates the dependence of the system behavior on its parameters. The bifurcation phenomena and a mapping of the parameter space have been presented. This knowledge is vital for designing practical circuits.
A Review of Experiential School-Based Culinary Interventions for 5–12-Year-Old Children

Cooking is an essential skill and the acquisition of cooking skills at an early age is associated with higher diet quality. This review aimed to describe the characteristics of school-based experiential culinary interventions and to determine the value of these to child (5–12 years) health outcomes. Interventions were eligible for inclusion if they took place in school during school hours, included ≥3 classes, and had a control group. Interventions published up to May 2021 were included. The databases searched were PubMed, CINAHL, and EMBASE, and the grey literature was searched for published reports. The search strategy yielded 7222 articles. After screening, five published studies remained for analysis. Four studies targeted children aged 7–11 years, and one targeted children aged 5–12 years. The interventions included food tasting, food gardening, and/or nutrition education alongside experiential cooking opportunities. Improvements were evident in self-reported attitudes toward vegetables, fruits, and cooking, and two studies reported small objective increases in vegetable intake. School-based experiential cookery interventions have the potential to positively impact health-related aspects of the relationship children develop with food. However, a greater number of long-term methodologically rigorous interventions are needed to definitively quantify the benefits of such interventions.
