Optimal PWM in Three-Level Inverter for THD Minimization with Quarter
Wave Symmetry Relaxed
Authors: Rai Neerparaj , Chakravorty Sandeep 
Published: April 2022

Background:
Previous works on total harmonic distortion (THD) minimization for multilevel inverters (MLI’s) has made a symmetrical approach that imposes Quarter Wave Symmetry (QWS) and Half Wave Symmetry (HWS) with the aim to restrict the computational difficulties to solve the finalized non-linear expressions.

Objective:
However, QWS constraint can be abolished, which leads to more generalized formulations and multiple solutions corresponding to minimum THD for complete modulation index-range.

Methods:
A systematic search approach using MATLAB in-build function is adopted to investigate ideal angles of switching related to three-level, three-phase inverter restricted to only HWS as a constraint for two and three (i.e., N= 2 and 3) switching transitions per quarter cycle.

Results:
On account of the effective minimization of the dominant low-order odd line voltage harmonics, the proposed pulse-width-modulation (PWM) scheme proved its superiority based on minimum THD% performance compared to the previously reported PWM techniques with both HWS and QWS being retained.

Conclusion:
The simulation, as well as experimental results to confirm the efficacy of the proposed non-symmetrical PWM scheme over the traditional PWM method restricted to QWS and HWS symmetries over the entire modulation-index range with added advantage of general formulation and multiple solutions.

Background:
Cervix preparation is one of the main steps in the onset of labor and is
very important for success in initiating or inducing labor.

Objective:
The present study aimed at investigating the effect of evening primrose vaginal capsule
on the preparation of cervix and the consequences of labor in nulliparous women.

Methods:
This randomized clinical trial study was conducted in 2018 on 100 nulliparous women
referred to Fatemieh Hospital in Hamadan. In intervention group (50 people), one evening primrose
capsule (500 mg) was used vaginally and then two hours later, another capsule was used, and
placebo was used in the control group (50 people). Then, the dilatation, effacement, Bishop scores
and duration of the first stage of the labor were compared in two groups after 4 hours. Statistical
analysis was performed with SPSS 21. The significance level was considered to be 0.05.

Results:
There was a statistically significant difference in the mean score and standard deviation of
dilatation, effacement of cervix, bi-shop scores and duration of the first stage of labor four hours
after the intervention in the intervention and Placebo groups by controlling the effect of potential
confounding factors (P <0.001).

Conclusion:
The results showed that the use of evening primrose vaginal capsules can reduce the
length of the first stage of labor, improve Bishop score, and soften and ripen the cervix.

The estimation of yield component genetic parameters is an important step towards plant breeding activities. This research aims to obtain information about yield components that can be used to increase yield of yardlong bean and accessions of yardlong bean for direct use or breeding materials. The research was conducted at Agrotechnology Innovation centre of Universitas Gadjah Mada, located in Kalitirto, Berbah, Sleman, Yogyakarta. The research materials consist of 29 accessions and 5 high yielding varieties as controls arranged in completely randomized design. Each accession was observed morphologically including days to 75% of ﬂowering, days to ﬁrst harvest, pod length, pod diameter, number of pods per cluster, number of pods per plant, number of seeds per pod, weight of 100 seeds, seed length, the diameter of seed, potential yield pods per hectare. Observed data were analyzed with ANOVA followed by the estimation of genetic parameters and principal component analysis. The results showed that almost all traits had a high heritability value, except seed length which had a moderate heritability value. Accessions 113, 134, 135, dan 137 could be considered as the promising candidates based on the earliest days to ﬁrst harvest and highest potential yield.

Introduction. The article examines peculiarities of missionary activities performed by the Russian Orthodox Church among Buddhists of Eastern Siberia in the mid-to-late 19th century. Goals. The paper aims to analyze — in social and archaeographic perspectives — a Tibetan manuscript collection at the Institute for Mongolian, Buddhist and Tibetan Studies (SB RAS) compiled through efforts of the Orthodox Christian missionary Konstantin K. Stukov (1809–1883). Materials and methods. The so called ‘cognitive history’ and certain elements of historical phenomenology serve as a methodological basis of the research. The structure of the Stukov Collection contributes to further understanding of both functioning patterns inherent to mid-to-late 19th century Buddhist communities of Eastern Siberia — and essentials of concurrent Orthodox Christian missionary endeavors across the region. The main research problem is to determine the substantial specifics of this collection for subsequent reconstruction of certain aspects in missionary activities of the priest. Conclusions. Ven. Stukov was interested in exploring worldviews and ritual practices of lay Buddhists for the cause of his missionary work. Those to be learnt knowledge areas (besides fundamental Buddhist doctrines proper) were to include visions of life characteristic of native inhabitants and largely rooted in pre-Buddhist culture of Siberia, South and Inner Asia. And the paper suggests that very interest proved crucial to the success of Ven. Stukov’s missionary deeds. The analysis claims personal initiative was an important factor of missionary work in mid-to-late 19th century Eastern Siberia integral to the then (and there) government policies at large. The article also introduces some newly discovered episodes from the biography of Konstantin K. Stukov — an Orthodox Christian priest, ethnographer, and social activist.

Introduction. The article presents insufficiently studied aspects of endeavors tackled by V. N. Tatishchev (1786–1750). His contribution to the study of antiquities in the Urals and Siberia is commonly accepted but his efforts on the research of Golden Horde monuments in the Lower Volga and North Caucasus were never decently appreciated. A prominent government official to have held different positions, he had been collecting materials for works on Russia’s history and geography since 1720. He made the preparation of maps (‘Landkarten’) and drawings to be a prerequisite for any historical research. Materials and methods. The study analyzes works by Vasily N. Tatishchev, his epistolary heritage, maps — both published and archival ones. The employed research methods include historical systemic, comparative and cartographic ones. Results. When holding the office of Astrakhan Governor from 1741 to 1745, he initiated a mapping of ruins of Golden Horde towns in the Lower Volga. In July of 1742, he arranged an expedition to Majar in the North Caucasus. The latter included engineering corps conductor A. Golokhvostov, painting apprentice M. Nekrasov, and twenty Cossacks. The participants made three drawings of Majar, several townscapes of Kizlyar and Braguny village which were sent by V. N. Tatishchev to Petersburg. In 1743, he requested the Senate to dispatch two land surveyors. S. Chichagov and S. Shchelkov arrived in the summer of 1744 to further prepare about seventy five maps including those of Greater and Minor Kabardia which were found and published in 2009 by E. Gusarova. The research materials of 1742 and 1744 were presented by Vasily N. Tatishchev in his Russian History that mentions the towns of Majar, Tatartup, and ‘Yulat’ (i.e. Julat located on the ancient site referred to as Nizhny Julat). Conclusions. The works of 1742 were pursuing purely scientific goals, while those of 1744 were to meet mainly operative needs. So, the available materials make it possible to recognize Vasily N. Tatishchev as an organizer of earliest explorations of Golden Horde monuments in the North Caucasus, such as sites of ancient Majar, Nizhny Julat, and Verkhny Dzhulat (Tatartup). Vasily N. Tatishchev’s resignation from the office of Astrakhan Governor in 1745 suspended academic investigation of monuments in the Lower Volga and North Caucasus. It is necessary to continue the search of archival materials dealing with the topic.

Published: April 2022

Este estudo analisa as causas da mortalidade e a distribuição espacial dos óbitos ocorridos por doença falciforme (DF) no estado do Espírito Santo (ES), Brasil, entre os nascidos vivos (NV) durante o período de 2001 a 2013. Trata-se de um estudo epidemiológico de análise de dados secundários, extraídos do Sistema de Informação de Mortalidade (SIM), do Programa de Triagem Neonatal do ES (PTN-ES) e do Sistema de Informação sobre Nascidos Vivos (SINASC). No período, foram registrados 649.187 NV, dos quais 86,3% foram testados pelo PTN. Dentre esses, 339 foram positivos para DF, com um coeficiente de incidência de 60,5/100 mil NV. Desses, 59,3% apresentaram genótipo HbFS, e 29,2% HbFSC. Foram identificados 31 óbitos no SIM, sendo 83,9% por DF e agravos relacionados e 16,1% sem DF declarada como causa de morte, porém ocorridos em crianças que haviam sido diagnosticadas com DF pelo PTN. A taxa de mortalidade total por DF foi de 4,8/100 mil NV, sendo 4,6 vezes maior entre as crianças não testadas pelo PTN em comparação àquelas que foram testadas, com taxas de 14,6/100 mil e 3,2/100 mil, respectivamente. Os maiores índices de óbito foram registrados nas áreas metropolitanas e litorânea do estado, sendo 64,5% do sexo masculino e 58,1% com idade entre 1 e 5 anos. Apesar da cobertura do PTN-ES estar acima da média nacional, houve uma lacuna de cerca de 14% na triagem dos NV, com taxas mais elevadas de óbito entre as crianças que não foram testadas. Tais achados enfatizam a importância da triagem neonatal para melhor sobrevida dos afetados pela DF.

O objetivo deste estudo é fornecer informações sociodemográficas e de características individuais de adultos, relacionados à participação de atividade física (AF) da população residente na cidade de Salvador, Bahia, na expectativa de gerar informações que auxiliem a elaboração de políticas públicas direcionadas à promoção da saúde da população soteropolitana. Foram analisados dados de 2.030 adultos (≥ 18 anos de idade) de ambos os sexos, participantes do sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (Vigitel) de 2018. Os homens estavam fisicamente mais ativos do que as mulheres no lazer e no trabalho, enquanto as mulheres estavam mais ativas nas atividades domiciliares. Ser solteiro e/ou divorciado e ter maior escolaridade parece favorecer a participação em AF. Entre os cinco tipos AF recreativa mais praticados, a caminhada foi a atividade mais prevalente em ambos os sexos, com 24,7% e 21,3% da população feminina e masculina, respectivamente, seguida de musculação (7,2%), ginástica geral (5,0%), futebol/futsal (4,0%) e corrida (3,0%). A participação de musculação, futebol/futsal e corrida foi mais frequente na parcela masculina da população, enquanto a participação de ginástica geral foi alavancada pela atuação feminina. A persistência dos estereótipos de gênero pode explicar, em partes, a diversidade e a prevalência em certas modalidades de AF entre homens e mulheres. A continuidade e a periodicidade do monitoramento da AF pelo Vigitel permitirão o acompanhamento das tendências comportamentais da população de Salvador em relação à participação de AF, enquanto estudos futuros, com metodologias apropriadas, poderão explicar as diferenças dos padrões de AF entre os sexos.

O funcionamento das organizações de forma fragmentada tem interferido na resolutividade do cuidado. Por isso, como estratégia da Política Nacional de Saúde Bucal para garantia da atenção secundária em saúde estão os Centros de Especialidades Odontológicas (CEO). Este estudo, de caráter exploratório transversal retrospectivo e abordagem quantitativa, objetivou analisar a organização dos serviços de atenção secundária em saúde bucal em um município do Nordeste brasileiro. Para tal, apoiou-se no fluxo de usuários e utilização desse nível de atenção e buscou o número de especialistas e usuários atendidos no ano de 2017 nos seis CEO existentes no território. Quanto à utilização dos serviços prestados pelos CEO, foi considerada a produção referente ao ano de 2017, disponível no Sistema de Informações Ambulatoriais (SIA). A pesquisa constatou que a oferta de atendimento disponibilizada foi menor do que a potencial nos seis CEO estudados. Identificou-se a falta de parâmetros de vinculação para referência de usuários aos CEO por meio da representação do fluxo de usuários em um mapa.

Hyperbaric oxygenation (HBO2) is a successful treatment of diabetic foot ulcerations. Research on the characterization of tissue by ultrasonography (CATUS) or by imaging (CATIM) has grown. We investigated the photographic pCATIM feasibility to quantitate HBO2 effects. Besides, we analyzed pre and post HBO2 treatment photographs quantitatively based on pixel brightnesses of gray-scale imaging versions. Grayscale Medians (GSM) for (1) entire ulceration, (2) inner core, (3) ulceration border, and (4) adjacent skin decreased from 92 to 77, 60 to 56, 105 to 101, and 105 to 90. Entire ulceration post-HBO2 pixel percentages were lower in the 112-153 intervals, 11% vs 29% (p = .0013 by Chi-square), and higher in the 41-111 brightness range, 87% vs 68% (p = .0008). A case report showed quantifiable relative changes detected by pCATIM post HBO2 treatment of diabetic foot ulceration. Further investigation may quantify brightness variabilities and/or specific GSM for ulceration and skin regions.
Common femoral artery doppler findings pre and post hyperbaric oxygen therapy for leg ulceration
Authors: Maran Cristiane Antequeira , Salles-Cunha Sergio Xavier 
Published: April 2022

Hyperbaric Oxygen Therapy (HBOT) assumes that high pressure hyperoxygenation causes faster tissue recovery and wound healing. Lower extremity flow rates are affected by leg ulcers that change vasodilation, microcirculation resistance, and local tissue demands; how blood hyper oxygenation influences these factors is still unclear. Peripheral arterial occlusive disease (PAOD) has been mostly associated with HBOT results in the femoral artery than in other arteries. Common femoral artery (CFA) peak systolic velocities (PSV), measured pre and post HBOT, were analyzed to research HBOT hemodynamics. Sixteen patients with leg ulcers who were 65 ± 11 (SD) (38-87) years-old, had HBOT of 90 minutes at 2.6 ATA. Bilateral CFA Doppler velocity waveforms were recorded immediately pre and post HBOT. Ulcerated vs non-ulcerated peak systolic velocity (PSV) data were compared using paired t-test. CFA PSV were significantly equal in the ulcerated and non-ulcerated extremities before HBOT: 114 ± 35 (SD) cm/s vs 116 ± 41 cm/s (p = 0.87 by paired t-test). CFA PSV in the ulcerated extremity increased to 122 ± 35 cm/s after HBOT but were statistically insignificant (p =.19 by one-tailed paired t-test). On the other hand, CFA PSV decreased to 103 ± 28 cm/s (p =.049 by one-tailed paired t-test) in the non-ulcerated extremity and were significantly lower after HBOT, with 103 ± 28 cm/s vs 122 ± 35 cm/s for the ulcerated limb (p =.02 by paired t-test). Blood velocity responses post HBOT showed differences between ulcerated vs non-ulcerated extremities. The non-ulcerated extremity apparently responded to oxygenation more than the ulcerated extremity. Such observation suggests further research on hemodynamic reactions caused by HBOT.
