Published: August 2022

Edaravone (EDV, 3-methyl-1-phenyl-2-pyrazolin-5-one) is a neuroprotective drug that has been used to treat acute stroke caused by cerebral thrombosis and embolism. Studies showed that EDV could be used to treat diseases related to oxidizing agents; however, the activity has not been fully studied yet. In this study, the free radical scavenging activity of EDV was investigated by thermodynamic and kinetic calculations. The results showed that EDV exhibited good HOO• radical scavenging activity in an aqueous medium at pH = 7.40 (koverall(HOO) = 8.58´107 M-1 s-1) through the electron transfer mechanism of the anion state. In contrast, this activity was insignificant in non-polar environments. EDV also exhibited excellent antiradical activity against HO·, CH3O·, CH3OO·, O2·-, NO2, SO4·-, N3· and DPPH radicals in the aqueous solution. Thus, it appears to suggest that EDV is a promising radical scavenger in polar environments.

Authors: Tesaev Zelimkhan Adamovich , Suleimanov Zelimkhan Zhalaudinovich
Published: August 2022

The article discusses the abstract compiled by the Jordanian military and researcher – Abd-ul-Ghani Hassan al-Shiishani (1924-2001) – to the manuscript of the medieval theologian and preacher Azdi Wazar, kept in the archive of Sheikh Bahal Tolmirzi az-Zandaki (1784-1884). The text of the Arabic-language document was sent in 1990 by letter to the Chechen ethnographer and writer A. S. Suleymanov, stored in the manuscript fund of the museum of the same name. According to the contents of the document, Azdi Vazar (1395-1460) was born in the family of the Tatar officer Vazar Andarbi, studied in the countries of the East and visited Chechnya with a preaching purpose.   The text lists forty-eight sub-ethnonyms, declared as a list of tribes known to Azdi Vazar at the time of his arrival in his homeland. A number of toponyms are given, as well as brief background information on the religious picture and geographical boundaries of the region. The document is being introduced into scientific circulation for the first time. The article is divided into three parts and represents the history of the document, the comments of the author of the publication regarding certain points from the annotation and the actual text of the translation of the annotation by A.-G. H. Ash-Shiyshani. Some points reflect additional information gleaned from his own (Al-Shiishani) Chechen-language translation of the Arabic annotation.
Ethnic minorities in the Middle East: realities and prospects of status transformation in the Geopolitical system
Authors: Malov Maksim Anatolyevich
Published: August 2022

The subject of the study is the direction and nature of the change in the status of small ethnic groups and ethnic confessions stationed in the Middle East for a long time. The article analyzes the development of the political and legal situation of small ethnic groups of Middle Eastern countries, affecting international relations, reveals the main positions of preservation and development of small peoples of Turkey, Iran, Iraq, Syria, Israel, which is relevant due to the artificial creation of most states of the Middle East and the ethnic diversity of this region. The author separately examines such aspects of the topic as the interference of external actors in the politics of the Middle East countries with the help of ethnic groups and diasporas. The novelty of the study lies in the comprehensive consideration of a wide range of factors affecting the relationship of small ethnic groups and states of the Middle East. The main conclusions of the study are that now, when the North-South dichotomy and the division into developed and developing countries is blurring, and outside actors cannot fully influence the situation with their authority, the states of the Middle East themselves need to choose a strategy for modernizing and transforming the status of their small ethnic groups in accordance with both their requirements and the general socio-cultural situation in this country and the requirements of the international agenda.
Improving Access and Health Outcomes in Palliative Care through Cultural Competence: An exploration of opportunities and challenges in India
Authors: Kashyap Komal , Gielen Joris
Published: August 2022

People who belong to ethnic, racial and cultural minorities often have less access to healthcare and have poorer health outcomes when compared to the majority population. In the COVID pandemic, too, health disparities have been observed. Similar disparities have been noted in patients with advanced disease and suffering from pain, with minority patients having less access to or making less use of palliative care. In the US, a range of solutions has been proposed to address the issue of inequality in access to healthcare, with cultural competence figuring prominently among them. This study explores whether and how cultural competence may be applied to palliative care in India to improve access and health outcomes. In the literature, it is argued that, in diverse societies, cultural competence is an essential part of the solution towards equitable healthcare systems. Solutions to problems of healthcare disparities must go beyond an increase in financial resources as more financial resources will not necessarily make the healthcare system more equitable. A culturally competent system recognises and integrates at all levels the culture as a significant component of care, which is particularly relevant at the end of life. If efficiently implemented, cultural competence will lead to higher patient satisfaction, better follow-up and patient compliance and an improved reputation of palliative care among minorities. This may help to reduce inequalities in access and health outcomes in palliative care.

Published: August 2022

The aim of this report is to describe our experience in endovascular treatment of May–Thurner syndrome. We report three cases of iliocaval stenosis treated endovascularly at our institution. We included three patients age range from 41 to 85 years with two presenting with acute deep vein thrombosis and associated limb swelling and one with chronic lower limb symptoms. We reviewed the technical success, complications, and stent patency on follow-up, latter was monitored be serial imaging. The three cases of iliocaval stenosis were treated with endovascular stenting with follow-up imaging follow-up period ranged from 6 to 13 months (mean 5.6 months) with two out of the three cases maintaining stent patency. One case was complicated by intraprocedural reopening of previously venous bleed. Clinical symptoms resolved with no recurrence in two out of three cases. One case experienced symptomatic in-stent thrombosis following endovascular treatment. Endovascular treatment of iliocaval stenosis appears effective in immediate technical success. Periprocedural attention to anticoagulation and stent position are important in preventing in-stent restenosis.

Authors: Ilham Firman Ashari  , Idri Mohamad , Nasrulah M. Anas
Published: August 2022

Security is very important everywhere, including in the campus environment. To provide security and comfort for those who park their vehicles, a parking application is needed that can provide vehicle security while undergoing academic activities on campus. QR code (Quick Response Code) is a technology for converting written data into a two-dimensional code, which is printed on a more compact medium capable of storing various types of data. The most common individual part used to identify a person is the face because it has the unique characteristics of everyone. Histogram of Oriented Gradient (HOG) is a feature extraction used for face identification based on histogram of gradient orientation and gradient magnitude. This application is implemented using the Dlib library for facial recognition. The implementation of this method is expected to improve parking security and provide a record of parked vehicles. The results of testing the implementation of facial recognition methods into android applications show very satisfactory results. With the results of testing the QR code scanning accuracy of 100% and an accuracy of 90% for a 7% damage rate and an accuracy of 85% for a 15% damage rate, and the results of facial recognition testing of 90% on face photos wearing helmets and an accuracy of 92% on photo of face without helmet.

The chemical industry is a major source of economic productivity and employment globally and among the top 3 industrial sources of greenhouse gas (GHG) emissions, along with steel and cement. As global demand for chemical products continues to grow, there is an urgency to develop and deploy sustainable chemical production pathways and re-consider continued investment in current emissionintensive production technologies. This Perspective describes the challenges and opportunities to decarbonize the chemical industry via electrification powered by the low-emission electric power sector, both in the near-term and long-term, and discusses four technological pathways ranging from the more mature direct substitution of heat with electricity and use of hydrogen to technologically less mature, yet potentially more selective approaches based on electrochemistry and plasma. Finally, we highlight the key elements of integrating an electrified industrial process with the power sector to leverage process flexibility to reduce energy costs of chemical production and provide valuable power grid support services. Unlocking such plant-to-grid coordination and the four electrification pathways has significant potential to facilitate rapid and deep decarbonization of the chemical industry sector.
Evaluation and optimization of electrocoagulation process parameters for the treatment of oil drill site wastewater
Authors: Kumar Pramod , Nawaz Tabish , Singh Swatantra Pratap
Published: August 2022

The effluent from the oil drilling site is a complex mixture of harmful chemicals that causes environmental impacts on its disposal. The treatment of oil drilling site wastewater has not been explored in-depth in the available literature and requires understanding about its characteristics and optimization of the treatment process. In the present study, we have optimized the electrocoagulation process with aluminum electrodes for the drill site wastewater treatment. A multi-level factorial center composite design using response surface methodology (RSM) is applied to quantify the individual and combined effect of the current density, pH and inter-electrode distance (IED) on the COD removal from the drill site wastewater and the energy consumption of the electrocoagulation process. The increasing current density shows significant increase in COD removal. A similar trend was observed with decrease in pH on COD removal. The model obtained from RSM study predicted the optimum current density, pH, and IED within the experimental range of the study. It was found that the optimum condition for DSW-1 samples for 78% COD removal is at 4.76 mA/cm2 and 4 pH, and for DSW-2, we get the COD removal of 64% at 19.04 mA/cm2 and 1.2 cm IED. The study shows that the current density is the dominant factor for the process's energy consumption and operating cost as compared to the pH and IED. The study demonstrated optimization of the electrocoagulation process in drill site wastewater treatment and could be effectively used for large-scale treatment through the electrocoagulation process.
Biased quartz crystal microbalance method for studies of CVD surface chemistry induced by plasma electrons
Authors: Niiranen Pentti , Nadhom Hama , Zanaska Michal , Boyd Robert , Sortica Mauricio , Primetzhofer Daniel , Lundin Daniel , Pedersen Henrik
Published: August 2022

In a recently presented chemical vapor deposition (CVD) method, plasma electrons are used as reducing agents for deposition of metals. The plasma electrons are attracted to the substrate surface by a positive substrate bias. Here, we present how a standard quartz crystal microbalance (QCM) system can be modified to allow applying a DC bias to the QCM sensor to attract plasma electrons to it and thereby also enable in situ growth monitoring during the electron-assisted CVD method. We show initial results from mass gain evolution over time during deposition of iron films using the biased QCM and how the biased QCM can be used for process development and provide insight to the surface chemistry by time-resolving the CVD method. Post deposition analyzes of the QCM crystals by cross-section electron microscopy and high-resolution X-ray photoelectron spectroscopy, show that the QCM crystals are coated by an iron-containing film and thus function as substrates in the CVD process. A comparison of the areal mass density given by the QCM crystal and the areal mass density from elastic recoil detection analysis and Rutherford backscattering spectrometry was done to verify the function of the QCM setup. Time-resolved CVD experiments show that this biased QCM method holds great promise as one of the tools for understanding the surface chemistry of the newly developed CVD method.

Objectives.

To determine changes to income and livelihood, food consumption, and hunger due to coronavirus disease 2019 (COVID-19) in three Small Island Developing States (SIDS) in the Caribbean: Jamaica, St Kitts and Nevis, and St Vincent and the Grenadines.

Methods.

This was a cross-sectional study conducted in July 2020. Participants were selected using telephone directories and lists of mobile numbers. Data were collected through face-to-face and telephone interviews. Participants rated the impact of COVID-19 on their livelihoods and the Adult Food Security Module was used to assess hunger. To examine how these outcomes varied by sociodemographic group, multivariable logistic regression analysis was used, with odds ratios (OR) and 95% confidence intervals (CI) reported.

Results.

The analysis included 880 participants. Of these, 40% (344/871) reported some form of hunger, with 18% (153/871) classed as moderate-to-severe hunger. Almost three quarters of households reported some impact on their livelihood (640/880), with 28% (243/880) classifying this impact as moderate to severe. Women were 60% more likely to report that their livelihoods were moderately to severely affected by COVID-19 (OR 1.59; 95% CI 1.09, 2.31) and 70% more likely to experience moderate-to-severe hunger (OR 1.70; 95% CI 1.37, 2.09). The effects of COVID-19 on livelihood and hunger were greater in those with secondary-school and primary-school education compared with tertiary education.

Conclusion.

The COVID-19 pandemic is disproportionately affecting the most vulnerable segments of the population. Social protection programmes are a key component of efforts to alleviate the pandemic’s consequences; however, equitable access must be ensured.
Cordéis de Pedro Macambira: comunicação popular e alternativa no contexto do movimento sindicalo do movimento sindical
Authors: Miani Rozinaldo Antonio
Published: August 2022

O movimento sindical brasileiro, especialmente durante a vigência do “novo sindicalismo”, se constituiu em um ambiente fértil para a produção de experiências comunicativas alternativas. Além de jornais, boletins, revistas e cartazes, outras produções impressas também circularam entre trabalhadores de várias categorias levando informações e discussões sobre o contexto da luta sindical e sobre temas da conjuntura social e política pela ótica da classe trabalhadora. Dentre essas experiências, a literatura de cordel também teve o seu espaço e importância. Nesse sentido, o objetivo deste artigo é apresentar e analisar a obra de Pedro Macambira que, além de operário metalúrgico e liderança sindical, foi produtor de diversos cordéis que pautaram temas sindicais como greves, eleições sindicais e comissão de fábrica, bem como temas políticos como a eleição presidencial de 1989. A análise aponta para o reconhecimento dos cordéis de Pedro Macambira como prática política discursiva e como expressão singular de comunicação popular e alternativa no contexto do movimento sindical brasileiro.
Mídia regional e produção científica no Norte do Brasil
Authors: Silva Lucas Braga da , Meneses Verônica Dantas
Published: August 2022

Este artigo se propõe a analisar as publicações sobre mídia regional em seções de temas livres de periódicos ligados aos cursos de jornalismo de universidades públicas do Norte do Brasil em 2017 e 2018. Trata-se de uma revisão sistemática nos periódicos abertos da área de comunicação a partir de descritores relacionados ao tema. Os resultados demonstram que, dos sete estados situados na região, dois publicam periódicos na área de comunicação. Observou-se também que há poucos estudos relacionados com a mídia regional: de um total de 170 trabalhos publicados em 2017, apenas 17,64% (30) estavam relacionados a essa temática e, no ano de 2018, de 140 pesquisas divulgadas, cerca de 18,57% representam a pesquisa do campo. Outro dado importante é que a referida região possui somente quatro periódicos com enfoque em comunicação. Conclui-se que o espaço destinado pelas revistas aos temas livres recebeu poucos artigos relacionados à mídia regional. Contudo, é importante destacar o potencial de contribuição dos veículos de comunicação regionais para o desenvolvimento local e para o fortalecimento das identidades.
Entre votos e concessões: o telejornal Diário da Constituinte e o tema da comunicação social em 1987
Authors: Dos Santos Teixeira Carla Drielly
Published: August 2022

Este trabalho trata sobre o tema da comunicação social e o conteúdo veiculado no telejornal Diário da Constituinte, lançado em abril de 1987. O noticioso oficial foi responsável por divulgar, em rede nacional de televisão, os trabalhos da Assembleia Nacional Constituinte (ANC). As análises das edições de estreia tomam o DC como fonte e objeto de pesquisa com o intuito de mostrar como o debate sobre a comunicação social divulgado pelo telejornal se desenrolou ao longo de 1987. Percebe-se que a despeito de suscitar valores republicanos e democráticos em suas edições, as práticas do patrimonialismo, clientelismo e da acomodação/conciliação, predominaram na distribuição de concessões de radiodifusão e foram decisivas para o resultado final da ANC. O texto está dividido em duas partes: a primeira se ocupa de analisar as edições de estreia do DC e a segunda cuida dos interesses e conflitos em torno do tema da comunicação social na ANC.
Antes do cabo: as agências de notícias na imprensa brasileira no período pré-telegráfico (1851-1874)
Authors: Aguiar Pedro
Published: August 2022

O artigo resgata a história do uso do material de agências de notícias na imprensa brasileira antes da instalação do cabo telegráfico submarino de 1874, que frequentemente é tomada como marco inicial para a atuação dessas empresas no país. Recorrendo a buscas textuais no acervo da Hemeroteca Digital Brasileira, da Biblioteca Nacional, o levantamento propõe uma nova datação para a relação entre jornais e agências no Brasil, retrocedendo a 1851, com as primeiras menções a uma agência de notícias na imprensa brasileira (a austríaca KKTK), e intensificando-se em 1854, na cobertura da Guerra da Crimeia. No intervalo desde então até a instalação do cabo, foram identificadas mais de 500 citações a despachos de agências de notícias europeias (Havas, Reuters, Stefani, Fabra, Lejolivet) e uma norte-americana (Associated Press) nos jornais digitalizados. A pesquisa, assim, contesta a datação convencionada na historiografia canônica da imprensa no Brasil e propõe uma perspectiva de evolução gradual, e não repentina, da influência das agências sobre os jornais brasileiros.

Authors: Moura Flavia De Almeida , Ferreira Júnior José , Santos Jeyciane Elizabeth Sá
Published: August 2022

O objetivo deste artigo é contribuir para a análise do contexto em que se desenvolveram as ações dos movimentos sociais a partir da visibilidade midiática da luta contra o trabalho escravo contemporâneo no Brasil, por meio da apresentação de fatos que marcaram a trajetória de combate à escravidão moderna a partir de uma linha do tempo relacionada com a cobertura midiática. Os estudos tomam como ponto de partida os motivos que levaram ao reconhecimento de escravidão contemporânea no Brasil em 1995, além de recuperar a atuação da mídia brasileira para dar visibilidade às publicações sobre a temática. Também destaca os principais avanços, como a PEC do Trabalho Escravo (PEC 438/2001), uma medida aprovada pelo Congresso Nacional em 2014. A discussão centra-se, sobretudo, na necessidade de despertar o interesse em assuntos relacionados aos estudos da mídia com olhar voltado à participação dos movimentos sociais na produção de conteúdo.

A Nonlinear Autoregressive Distributed Lag (NARDL) Approach for U.S. Climate Policy Uncertainty Index, Renewable Energy Consumption, and Oil Prices
Authors: DİNC CAVLAK Ozge
Published: August 2022

This study aims to reveal the asymmetric relationship among climate policy uncertainty, oil prices, and renewable energy consumption for January 2000-March 2021 in the U.S. The long- and short-run dynamic impacts of oil prices and renewable energy consumption on climate policy uncertainty are mainly examined utilizing a nonlinear autoregressive distributed lag (NARDL) approach. The findings of the study depict that there exists an asymmetric cointegrating relationship between climate policy uncertainty, renewable energy consumption, and crude oil prices in the long run. Climate policy uncertainty is affected by both negative and positive variations in renewable energy consumption and oil prices in the long-run period. The presence of asymmetric relations is an indicator of the data is suitable for the NARDL model. The NARDL estimation results reveal that an increment in renewable energy consumption causes an increase in climate policy uncertainty while a decrease in renewable energy consumption also causes an increase in climate policy uncertainty in the long-run period. Further, an increase in oil prices causes an increase in climate policy uncertainty while a reduction in oil prices results in a decrease in the climate policy uncertainty for a long-run period.

The empowerment of MSMEs is an important thing. MSMEs empowerment aims to enable MSMEs to continue, develop and create employment opportunities for the surrounding population. Empowering MSMEs includes improving management and implementing appropriate strategies so that MSMEs can continue to survive in the future. MSMEs Go Nads, which engaged in fashion making of clothes made from traditional Indonesian fabrics, face the same problems as other MSMEs. This problem is an obstacle in developing Go Nads MSMEs. Internal and external factors from MSMEs are a constraint for MSMEs' growth. Internal factors include limited competency in human resources, capital, a simple business network, and limited ability to penetrate the market. External factors include limited facilities and infrastructure, free competition, and a business climate that does not support MSME activities. Therefore, the Untar team carried out community service activities by providing training on business management and development by making the IFE-EFE matrix. Matrix Internal Factor Evaluation (IFE) and External Factor Evaluation (EFE) is a tool to formulate a strategy consisting of internal and external factors. Internal factors are strengths, weaknesses, and external factors in the form of opportunities and threats that can occur in a business venture. The internal and external data is collected to analyze, identify and evaluate the relationship between the two so that it can implement business strategies, especially for MSMEs. The IFE and EFE matrices determine the position of MSMEs and the preparation of business strategies. The results of this PKM activity are that Go Nads MSMEs are in Quadrant I in the IE matrix. The position of the 1st Quadrant in the IE (Internal External) matrix shows the Go Nads SMEs position is in the growth and development stage. The right strategy is to penetrate the market and develop the market.
