Authors: Danupat Duangmalai  , Thosapol Manasri  , Adisorn Kwawsibsam  , Winai Jaikla
Published: March 2023

The multiphase sinusoidal oscillator (MSO) is useful for various electrical and electronic applications. This study aims to design an MSO employing voltage differencing differential input buffered amplifiers (VD-DIBAs). The design procedure is based on cascading the first-order low-pass filter. Each phase consists of a VD-DIBA, two resistors, and a grounded capacitor. An odd-phase system without requiring an additional amplifier. The frequency is electronically controlled through the bias current without affecting the condition. The sinewave amplitudes and the phase difference between each waveform are identical. The proposed MSO is designed to obtain three-phase waveforms (n = 3). PSPICE simulation demonstrates the performance of the proposed oscillator with 0.18 μm TSMC CMOS parameters with ±0.9 V power supply. The feasibility of the proposed MSO is also verified with experiments using the VD-DIBA constructed from commercial integrated circuits (ICs) with a ±5 V power supply. The simulated and experimental results align with theoretical predictions.
A Study on the Risk Probability of Risk Mitigation Alternatives at Non-Compliance Airport with Runway Strip Criteria
Authors: Do-Hyun Kim  , Hyo-Seok Chang  , Woong-Yi Kim
Published: March 2023

A runway strip is defined as the surface surrounding a runway established or suitable for reducing the risk of damage to aircraft in the event of a runway excursion. This study aims to implement the RSARA and LRSARA models at an airport not meeting the runway strip dimension criteria required by standards for aerodrome physical characteristics. The airport is considering alternatives to secure the runway strip criteria such as the displaced threshold and runway length extension, which is predicted to reduce the runway excursion probability. As the results of this study, it was discovered that the risk probability increases with the increases of the displaced runway distance due to relatively reduced runway length. Therefore, a reduced runway length to meet runway strip criteria may not be the most effective risk mitigation alternative, and it should be acknowledged that such a strategy can harm aviation Safety.

Published: March 2023

The electric field strength in the positive column of dc and bipolar pulsed discharges in carbon dioxide was determined by the method of moving electrodes. It is shown that an increase in the frequency of the pulse voltage leads to the electric field strength increase. The following values of the reduced electric field E/p for a gas pressure of 0.5 Torr were obtained: 22.5 V/(cmTorr) for dc discharge, 30 V/(cmTorr) for pulsed discharge at 20 kHz for lowcurrent mode and 32 V/(cmTorr) for high-current mode, and 36.6 V/(cmTorr) for 75 kHz. We see that in the dc discharge, the reduced electric field is weak, due to which the exchange of vibrational energy between CO2 molecules dominates the conversion process. The increase of the electric field strength in the positive column of a pulsed
discharge, especially under conditions of gas heating, allows obtaining E/N > 100 Td when the process of direct dissociation of CO2 molecules by fast electrons makes the main contribution to the conversion process.

Authors: Nedybaliuk O.A. , Fedirchyk I.I. , Maruschak M.S. , Chernolutsky D.L.
Published: March 2023

The effect of dielectric barrier discharge (DBD) treatment on the germination of beet seeds under different conditions was investigated. The emission spectra of the DBD plasma were measured under various operating conditions. It is shown that the main components of the emission spectra are nitrogen (N2) bands. The rotational (Tr) and vibrational (Tv) temperatures of the DBD plasma are determined from the N2 bands under different operating conditions. The dependences of the germination percentage of beet seeds at different time intervals of DBD treatment were obtained. The optimal time for treating beet seeds was determined.

Intra-limb Coordination and Control in Individuals with Stroke: Conceptual and Methodological Considerations
Authors: Przysucha Eryk
Published: March 2023

Background: A substantial amount of descriptive, rehabilitation and review research examined the behavioral (kinematic) nature of intra-limb organization in reaching and grasping actions in individuals who suffered a stroke. However, the majority of this work failed to explicitly address the level of movement organization affected, the conceptual relevance to existing theories of motor control, and the impact of different constraints on the emerging actions. Thus, the purpose was to examine whether the selected studies examined the issue in coordination and/or control, in the context of the existing conceptual frameworks. The second purpose was to delineate which individual and task constraints have been examined in previous work, and infer the degree to which these factors affected the nature of the emerging movement patterns.

Methods: The search of four databases (PubMed, Embase, Web of Science and CINAHL), including published work between January 2019 and March 2022, yielded twenty studies.

Results: Despite the fact that stroke substantially alters the emerging movement patterns majority of the studies examined issues in control, not coordination. In term of spatial and temporal control, the actions of individuals with stroke were slower and involved minimal use of the shoulder and elbow joints, as compared to their healthy counterparts. The analysis of emerging movement patterns, via inverse kinematics, showed that stroke resulted in segmented coordination between shoulder and elbow, while no studies examined the relations between distal anatomical structures (e.g., elbow and wrist). In terms of specific theories or models of motor control, most research was data-driven as only three studies made inferences to existing motor control theories (e.g., Equilibrium Point Hypothesis). In regards to the second purpose, time after stroke was the most impactful individual constraint which differentiated the nature of movement organization exhibited by those with and without stroke. The impact of variables such as gender and age, on performance of individuals with stroke, was not examined. From the methodological standpoint, lack of measures of intra-individual variability represents an important limitation in rehabilitation research reviewed.

Conclusion: Collectively, the understanding of how individuals with stroke organize their actions remains equivocal. This is due to a variety of different methodological approaches used (e.g., forward vs. inverse kinematics), limited insight into critical aspects of movement organization (e.g., coordination) and the effects of key individual constraints (e.g., age/gender) on the nature of emerging movements. Also, the fact that data driven research still represents the primary impetus in this clinical field undermines the validity of the emerging inferences.
Correlation Between Contrast Variability and Refractive Error
Authors: Thatte Shreya
Published: March 2023

Background: Contrast sensitivity, is defined as the ability to detect the lowest lumination difference between an object and the background. It is one of the main requisites for good quality vision as the eye works by perceiving an object by comparing the difference between the target and the background contrast difference.

Aims and Objectives: To assess patterns of contrast sensitivity functions in patients in different types of refractive errors using Pelli Robson chart and also to measure the severity of refractive error within each group and compared the contrast sensitivity function with severity in different types of refractive errors.

Material and Method: This cross-sectional study was conducted on 500 patients (Age range from 10 to 80 years) who presented with chief complaint of refractive errors mainly myopia and hypermetropia. Patients who had previous history of ocular surgery and other ocular co- morbidity were excluded from study. Selected patients were enrolled for the study after taking a written informed consent. The patterns of contrast sensitivity function in different types of refractive errors were recorded on a prescribed proforma with respect to: Visual acuity, type of refractive error, severity of refractive error, duration of refractive error, age of the patient, fundus examination and Contrast sensitivity. Statistical analysis was undertaken with P<0.05 significant.

Results: A mild decrease in contrast sensitivity was recorded in majority of patients i.e 250 patients (50%). Maximum decrease in contrast sensitivity was seen in 31-60 years age group. A statistically significant direct correlation (P<0.05) was observed between duration and variation in contrast sensitivity. Both the refractive error showed definite decrease in contrast sensitivity and compound astigmatism showed severe decrease in contrast sensitivity.

Conclusion: Despite having BCVA of 6/6, patients showed reduced contrast sensitivity, even without any retinal pathology, making it an essential part of a routine ophthalmic examination.
Accommodative Stimulus Response Curve of Emmetropes and Myopes
Authors: Yeo Anna CH , Kang Kok Kai , Tang Wilfred
Published: March 2023

Introduction: Myopes are suspected to be poorer at responding to accommodative stimuli than emmetropes, and this may worsen the degree of their myopia. The study aims to compare the abilities of young adult emmetropes and myopes in responding to accommodative stimuli, as indicated by their Accommodation Stimulus Response Curves (ASRCs) in a predominantly Chinese population.

Materials and Methods: Seventeen emmetropes and 33 myopes aged between 16 and 23 years (mean, 18.6 ± 1.2) were recruited, of whom 11 were progressing and 22 were non-progressing myopes. The ASRC gradients of subjects were measured using the methods of decreasing distance series (DDS), positive (PLS) and negative lens series (NLS).
Results: The ASRC is method dependent. The gradients of the curves are significantly different among 3 methods of measurement using single-factor ANOVA (F3.057 = 44.815, P<0.01). The slopes of the accommodative errors of all subjects were steeper using the NLS method, and the lags of accommodation increased with elevated demands. No significant differences in ASRC gradients were found between emmetropes, non-progressing myopes and progressing myopes for the range of accommodative demands for each method. Progressing myopes showed the highest error towards the higher demand compared with the emmetropes and non-progressing myopes.
Conclusion: Accommodative responses of myopes were more sluggish though there were no statistical differences in ASRC gradients between emmetropes and myopes. It is not certain if the poorer accommodative responses were a cause, or a consequence, of myopia.

Economia do crime: efeito deterrence para municípios de Minas Gerais no período de 2009 a 2019
Authors:   , Murta Sobrinho Arthur Bernardes Alves
Published: March 2023

O presente trabalho faz uma avaliação do efeito do aumento do efetivo policial e do encarceramento, consideradas variáveis de dissuasão, sobre a taxa de homicídios nos municípios do estado de Minas Gerais. Para tanto, optou-se pela abordagem econométrica que considera o uso de Variáveis Instrumentais, uma vez que esse tipo de abordagem usualmente inclui problemas econométricos que envolvem a endogeneidade. Nessa pesquisa, as variáveis ‘número de bombeiros por cidade’ ‘movimentação bancária per capita’ e ‘número de faltas disciplinares cometidas por custodiados do sistema prisional’ foram testadas como instrumentos. Para proceder ao estudo, foi construído um modelo utilizando um painel de dados, o que permitiu explorar tanto a dimensão temporal quanto a espacial, oferecendo, adicionalmente, a possibilidade de controle da heterogeneidade não observável entre as cidades. Além disso, foi considerada a presença de spatial displacement of crime (deslocamento espacial do crime). De modo geral os resultados indicam que no contexto empírico das cidades mineiras no período de 2009 até 2019 os instrumentos testados são fortes e relevantes, além disso é encontrado fortes indícios do efeito do espaço nas taxas de crime, mas quando adicionado nos modelos de Variáveis Instrumentais não foi possível retirar a endogeneidade para a variável “taxa de polícia” em nenhum dos modelos, enquanto que quando se utiliza uma matriz de distância geográfica é encontrado indícios do efeito do espaço na taxa de crimes, mas o R2 das estimações apresenta-se abaixo de 1%. Uma explicação é que o método de MQ2E possui um problema de eficiência em amostras pequenas. Idealmente, o método de VI deve ser usado com grandes amostras. Palavras-chave: Dissuasão.

Família ou famílias, eis a questão: debates sobre família no Congresso Nacional a partir da análise do PL 6583/2013 (Estatuto da Família) e do PLS 470/2013 (Estatuto das Famílias)
Authors:   , Alves Weverton Fernandes Bento
Published: March 2023

As disputas mais intensas no mundo atual estão diretamente relacionadas à família, notadamente, nas tentativas de sua definição, uma vez que implica em aspectos como a divisão sexual do trabalho e a reprodução social. Nesse contexto, as tensões acerca dessas disputas perpassam pelo debate político e vêm sendo incorporadas como agenda de governo, inclusive, na formulação e execução de políticas públicas. Dessa forma, identificados o Projeto de Lei nº 6583 de 2013 (PL 6583/13 – Estatuto da Família) que tramita na Câmara dos Deputados e o Projeto de Lei do Senado (PLS 470/2013 – Estatuto das Famílias) que tramitou no Senado Federal, cujo objetivo é de estatuir as relações familiares em um texto legal, a presente dissertação, a partir de uma pesquisa com abordagem quanti-qualitativa, por meio da análise estatística descritiva e da análise de conteúdo, analisa as definições de família no processo de tramitação das duas proposições legislativas no Congresso Nacional. Assim, constatou-se que a definição de família no PL 6583/213 consiste na família tradicional e está relacionada às racionalidades neoliberais e neoconservadoras com vistas à implantação do familismo no ordenamento jurídico brasileiro; no PLS 470/213 diz respeito à pluralidade familiar, uma vez que contempla as transformações sociais e não diferencia as várias estruturações familiares possíveis.

Australia's Sustainability: A New Policy Front for Rural Education?
Authors: Halsey R. John
Published: March 2023

Rural education and its policy agenda has for many decades primarily focussed upon responding to decline to keep things going; keep things open‘. While this has been understandable and much has been achieved, it is now opportune—essential?—that rural education and its leaders embrace a new  challenge, sustainability, and use it to pursue new policy fronts. The 25th anniversary of the Society for the Provision of Education in Rural Australia is a timely occasion to consider this. Five issues critical to national sustainability, and a program to engage city and urban youth in living and learning in rural communities, are presented to stimulate new policy and operational possibilities for rural education under the umbrella of sustainability.
Aboriginal Practical Experience and its Impact on Pre-service Teachers' Decisions About Living and Working in Remote Indigenous Communities in Australia
Authors: Jay Jenny , Moss Lynette , Cherednichenko Brenda
Published: March 2023

In June 2008, 10 pre-service teachers and 2 teacher educators from Edith Cowan University (ECU) participated in an existing community education program in rural and remote Indigenous communities in central Australia. From an intrepid start with a mountain of overloaded baggage and camping cutlery; setting off the scanning machine at the airport, these educational risk takers trekked off into the desert. Our explorers joined 60 pre-service teachers and several teacher educators from the Victoria University (VU) Story Writing in Rural Locations (SWIRL) project. This project has been operating annually for 14 years in communities around Alice Springs, some up to 400 km of dirt track away. This paper reports the powerful effect of a short lived experience on pre-service teachers' attitudes and experience of living and teaching in a remote community. The experience described here represents the beginning of an authentic approach to giving experiences to pre-service teachers which may support them to consider teaching in remote Indigenous communities as part of their teaching career.

Published: March 2023

Calculating nonlinear optical phenomena in a barium-strontium niobate photorefractive crystal we constructed a mathematical model of the two-dimensional linearly polarized Gaussian light beams propagation taking into account all components of the linear electrooptic tensor. We investigated the dependence of the light beam intensity on the polarization azimuth at the entrance of the crystal and on the direction of the external electric field applied to a photorefractive crystal. We determined the conditions under which the focusing of two-dimensional Gaussian light beams at the exit of the crystal is maximal.

O severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), responsável pela coronavírus disease 2019 (COVID-19), causa uma doença com apresentação clínica variável desde pacientes assintomáticos até quadros infecciosos respiratórios graves. Estudos recentes demonstraram que uma parcela de pacientes pediátricos apresenta semanas após o contato com o vírus uma resposta imunológica exacerbada, conhecida como Síndrome Inflamatória Multissistêmica Pediátrica (SIM-P). Objetivo: Conhecer as características da SIM-P no contexto da pandemia do COVID-19 em crianças. Metodologia: Revisão integrativa da literatura realizada nas bases de dados: PUBMED/Medline, Periódicos/CAPES e SciELO, utilizando-se os termos “Síndrome Inflamatória Multissistêmica Pediátrica” e “COVID-19”. Critérios de inclusão: estudos publicados entre março de 2020 e outubro de 2021, sem restrição de idioma, excluindo-se notícias, notificações, comentários ou cartas de apresentação. Resultados: Os pacientes costumam ser mais velhos predominando em hispânicos, latinos e afrodescendentes. Entre os sintomas destacam-se: febre, lesões cutâneo-mucosas, fadiga, mialgia, sintomas gastrointestinais, respiratórios, cardiovasculares e neurológicos e clinicamente possui similaridades com a doença de Kawasaki. Acredita-se que a doença é desencadeada por processo mediado por anticorpos e/ou imunocomplexos em resposta à infecção prévia, resultando em uma resposta inflamatória sistêmica intensa com aumento de citocinas pró-inflamatórias tais como: IL-1, IL-6, TNF-α. Os pacientes foram tratatos com imunomoduladores e esteróides e a maioria apresentou melhora dos sintomas em poucos dias. Conclusão: o SARS-CoV-2 possui papel central no desenvolvimento da SIM-P e, portanto, sendo importante identificação e diagnóstico precoce da SIM-P para tratar os pacientes e previnir complicações de maneira efetiva.

Published: March 2023

Increasing transport demand necessitates higher oil consumption, resulting in an increase in carbon dioxide (CO2) emissions, which is a major cause of air pollution. The use of electric vehicles (EVs) is becoming more common around the world. Recent advancements in lithium-ion battery technology have increased the improvement of EVs. In this work, a solar photovoltaic (PV) battery-based EV charging station is designed. Meanwhile, the overall system comprises a battery energy storage system (BESS), solar PV module, grid and EV charging station. Thus, the primary source for the charging station is the PV source but due to less power during the night, we included battery storage as a backup. Grid source is also recommendable for an uninterruptable power supply. An artificial neural network strategy is developed in MATLAB/Simulink for proper power management of the solar PV-battery based EV charging station connected to the AC grid. Moreover, by employing an adaptive neuro-fuzzy inference system (ANFIS) and PI controller-based MPPT, the grid voltage and current, real/reactive grid power and the maximum output power are obtained. The overall system is evaluated under different scenarios of irradiance level and temperature with a state of charge (SOC) greater than 10 % for simulation purposes. The result shows that during the night hour due to less power from the PV source, an artificial neural network begins to regulate the grid power so that it supplies power to the stationary storage and EV battery.

A territorialização do capital monopolista nem sempre se dá sob os cânones do mercado capitalista de terras, pois, muitas das vezes, a apropriação indevida está na base da formação fundiária. Trata-se da grilagem de terras como sustentáculo para o latifúndio, ação denunciada pelos camponeses. Neste contexto, o objetivo desta pesquisa foi compreender a luta pela terra no Território da Cidadania Cantuquiriguaçu, localizado no estado do Paraná. Nessa região existem históricos conflitos fundiários, resultado da luta camponesa contra a territorialização do latifúndio. A metodologia da pesquisa se consistiu no estudo bibliográfico e na observação assistemática desenvolvida durante os trabalhos de campo. É uma pesquisa de caráter exploratório e de base analítica qualitativa. O resultado foi a apreensão do movimento de produção do território, marcado pelo enfrentamento dos camponeses ao latifúndio. Deste processo derivou a conquista de vários assentamentos, os quais somente foram possíveis a partir da organização dos camponeses em movimentos socioterritoriais.

RwandaMAP
Authors: Robinet François
Published: March 2023

Le projet international et interdisciplinaire RwandaMAP a, depuis 2018, l’ambition de constituer un réseau de recherche international sur les traces mémorielles, archivistiques et patrimoniales du génocide des Tutsi. Il s’agissait de relever une série de défis (pertes ou destructions de certaines traces ; profusion d’archives, de données et de travaux scientifiques ; abondance de récits de natures diverses et de témoignages) rendant indispensable la création de dynamiques collectives d’enrichissement des savoirs. Cet article se propose de dresser un premier bilan du projet en présentant ses objectifs et sa philosophie, les réalisations déjà concrétisées ainsi que les questionnements soulevés par cette première phase de développement.

Low-Delay Video Communication System over Wireless Channels Based on HEVC and OFDM
Authors: Samayoa Paredes Yasser Estuardo
Published: March 2023

This thesis provides an analysis of the entire video communication system assuming a wireless, frequency- and time-selective channel under low-delay constraints. The whole system consists of a standard-compliant video codec (HEVC), a channel codec and a modem (OFDM). A design methodology in terms of the rate-distortion optimization and a suitable framework to asses the entire system is proposed. It has synchronization capabilities and a suitable metric that turns out to be a key component of the rate-distortion based optimization procedure.

The trade-offs and interrelations of the parameters that have the most significant impact in the total distortion and robustness of the video signal are investigated. By means of intensive and sufficient simulations of an entire video transmission chain, it has been shown that the multiple techniques introduced and described in this thesis are viable tools for the design and optimization of specific video communication systems and its components.
