Authors: Kravchuk Yu. , Tatarchuk Т. 
Published: March 2021

The purpose of the work. Statistical and experimental analysis of coating methods on the turbine nozzle apparatus to increase the temperature regime.
Research methods. Calculation method of finite elements, experimental.
The results obtained. Studies have shown that the use of thermally protective coatings TZP thickness of 250 мm with a thermal conductivity of 1 W / mK on the two steps of the turbine can implement one of two possibilities:
- at constant operating temperature of the blade material to increase the temperature of the gas in front of the turbine by about 100 °C, which will increase efficiency and fuel savings by more than 13 %;- without changing the temperature of the gas in front of the turbine - to increase the durability of the blades by about 4 times, due to a decrease in their operating temperature. The analysis of two methods of drawing TZP was carried out, in the work the estimation of a temperature condition of the nozzle device (CA) of the turbine of a high pressure of the engine, decrease in its temperature due to drawing TZP and increase of its resource is carried out. The problem was solved by applying TZP on the blades of the nozzle apparatus. The analysis of two methods of drawing TZP was carried out, the estimation of a temperature condition of the nozzle device (CA) of the turbine of high pressure of the engine, decrease in its temperature due to drawing TZP and increase of its resource is carried out.
Scientific novelty. The problem of creating efficient, economical and reliable gas turbines is the most difficult among the many problems that arise in the development of gas turbine construction. Important elements of turbines are working and nozzle blades, the material and design of which determine the allowable gas temperature in front of the turbine and thus directly affect the technical and economic performance of the gas turbine engine.
Practical value. The obtained results are important for the further development of aircraft engine construction, due to the application of TZP achieved an increase in the resource of CA from 40,000 hours to 67,000 hours.

AbstractSettingThe Canadian Community Health Survey (CCHS) is one of the world’s largest ongoing cross-sectional population health surveys, with over 130,000 respondents every two years or over 1.1 million respondents since its inception in 2001. While the survey remains relatively consistent over the years, there are differences between cycles that pose a challenge to analyze the survey over time.InterventionA program package calledcchsflowwas developed to transform and harmonize CCHS variables to consistent formats across multiple survey cycles. An open science approach was used to maintain transparency, reproducibility and collaboration.OutcomesThecchsflowR package uses CCHS survey data between 2001 and 2014. Worksheets were created that identify variables, their names in previous cycles, their category structure, and their final variable names. These worksheets were then used to recode variables in each CCHS cycle into consistently named and labelled variables. Following, survey cycles can be combined. The package was then added as a GitHub repository to encourage collaboration with other researchers.ImplicationThecchsflowpackage has been added to the Comprehensive R Archive Network (CRAN) and contains support for over 160 CCHS variables, generating a combined data set of over 1 million respondents. By implementing open science practices,cchsflowaims to minimize the amount of time needed to clean and prepare data for the many CCHS users across Canada.

Abstract
Objectives
The effectiveness of public health interventions for mitigation of the COVID-19 pandemic depends on individual attitudes, compliance, and the level of support available to allow for compliance with these measures. The aim of this study was to describe attitudes and behaviours towards the Canadian COVID-19 public health response, and identify risk-modifying behaviours based on socio-demographic characteristics.

Methods
A cross-sectional online survey was administered in May 2020 to members of a paid panel representative of the Canadian population by age, gender, official language, and region of residence. A total of 4981 respondents provided responses for indicators of self-reported risk perceptions, attitudes, and behaviours towards COVID-19 public health measures.

Results
More than 90% of respondents reported confidence in the ability to comply with a variety of public health measures. However, only 51% reported preparedness for illness in terms of expectation to work if sick or access to paid sick days. Risk perceptions, attitudes, and behaviours varied by demographic variables. Men, younger age groups, and those in the paid workforce were less likely to consider public health measures to be effective, and had less confidence in their ability to comply. Approximately 80% of respondents reported that parents provided childcare and 52% reported that parents in the workforce provided childcare while schools were closed.

Conclusion
Policies to help address issues of public adherence include targeted messaging for men and younger age groups, social supports for those who need to self-isolate, changes in workplace policies to discourage presenteeism, and provincially co-ordinated masking and safe school policies.

Published: March 2021

Objective. To understand changes in daily life emerging from the COVID-19 Pandemic in people with visual impairment from four cities of Colombia.
Methods. Exploratory-type, descriptive qualitative study. The study conducted 26 semi-structured interviews via telephone. The analysis process used the methodological design from the approach proposed by Taylor and Bogdan: following the discovery process, coding and relativizing of data.
Results. Three categories emerge: 1) Transformations in daily dynamics, 2) Barriers to mobility, and 3) Use of technology.
Conclusion. People with visual impairment report barriers to mobility to take public transportation, which can affect maintenance of their autonomy and independence. Using technological tools is identified as facilitators for the continuity of educational and work activities; however, some did not have computer literacy or the basic inputs for connectivity. Difficulties were identified to continue work activities and maintain income.
Seismically Derived Ground Tilts Related to the 2010 Chilean Tsunami

Published: March 2021

AbstractDeveloping new ways to observe tsunami contributes to tsunami research. Tidal and deep-ocean gauges are typically used for coastal and offshore observations. Recently, tsunami-induced ground tilts offer a new possibility. The ground tilt signal accompanied by 2010 Mw 8.8 Chilean earthquake were observed at a tiltmeter network in Japan. However, tiltmeter stations are usually not as widely installed as broadband seismometers in other countries. Here, we studied broadband seismic records from Japan’s F-net and found ground tilt signals consistent with previously published tiltmeter dataset for this particular tsunamic event. Similar waveforms can also be found in broadband seismic networks in other countries, such as Taiwan, as well as an ocean-bottom seismometer. We documented a consistent time sequence of evolving back-azimuth directions of the tsunami waves at different stages of tsunami propagation through beamforming-frequency–wavenumber analysis and particle-motion analysis; the outcomes are consistent with the tsunami propagation model provided by the Pacific Tsunami Warning Center. These results shown that dense broadband seismic networks can provide a useful complementary dataset, in addition to tiltmeter arrays and other networks, to study or even monitor tsunami propagation using arrayed methods.

Background: Convalescent plasma is considered a promising therapy for severe COVID-19 disease. It is collected from the voluntary donors. Measurement of the antibody titer is necessary before transfusion to predict the outcome in the recipients. Characteristics of the convalescent plasma donors in Bangladesh and their antibody titers are not known.Methods: Convalescent plasma was collected from the voluntary donors who survived the COVID-19 disease to transfuse to the severe COVID-19 patients under a randomized control trial. Total IgG antibody titer was measured in the donor plasma by indirect enzyme-linked immunosorbent assay. Data was collected in a preformed questionnaire before donor plasma collection.Results: The median age is 32 (18-55) years. Fever, cough, sore throat, diarrhea was most common among 68.3% of the symptomatic participants and the remaining 31.7% were asymptomatic at the time when they were RT-PCR positive. Overall, 57.1% of participants had mild symptoms, 11.1% had moderate symptoms and none had severe symptoms. Participants’ antibody titers were measured 41.68±14.072SD days after the RT-PCR positive date. Rapid qualitative test could not detect antibody in 11 (17.5%) potential donors. Of the remaining 52 (82.5%) antibody positive participants titer was measured in 43 participants and found 1:320 in 17 (27.0%) (n=63), 1:160 in another 17 (27.0%) (n=63) and 1:80 in rest of the 9 (14.28%) (n=63) Participants. The mean titer of the donors who were hospitalized during their illness (1:274.29) was statistically significantly higher (p=0.043, CI>95%). The mean titer was also higher in female than in male, symptomatic than asymptomatic participants and in donors of A positive blood group. However, these finding are not statistically significant. Antibody titer does not correlate with time of RT-PCR negativity from initial RT-PCR positivity, time from RT-PCR positivity to titer date, age and body mass index.Conclusions: All RT-PCR positive COVID-19 patients subsequently may not develop antibody. Although antibody titer among hospitalized symptomatic patients was significantly higher, further study is needed to recommend optimal convalescent plasma donor criteria.

Background: Fatigue and sleepiness experienced by nurses can put them at risk of making mistakes in medication administration and clinical judgment. In addition, fatigue and sleepiness can also lead to increased emotions towards co-workers, jeopardize their own safety, especially on the way home from work, and can reduce patient care.Methods: This study used an analytical research method with a cross-sectional study, involving 91 shift nurses. It was carried out by conducting interviews during the first break of the first morning cycle after holiday.Results: Results of this study indicated that all sociodemographic variables did not show significant differences with sleep quality variable with a significance level of p>0.05. There was also no relationship between physical activity and caffeine intake and sleep quality. Moreover, there was no significant difference between physical illness and sleep quality. Sleep quality (Pittsburgh sleep quality index/PSQI) and sleepiness level score (Karolinska sleepiness scale/KSS) showed no significant relationship with p<0.05. KSS was divided into 2 including non-sleepy state (1-6) and sleepy state (7-9).4 Insignificant relationship was also shown between sleep quality score (PSQI) and fatigue level score (fatigue severity scale/FSS). Importantly, insignificant relationship was shown between sleep quality score and hospital anxiety and depression scale. In addition, there was only work unit in COVID-19 isolation room which had a significant relationship to sleep quality compared to non-isolation room with a significance level of p<0.05. Conclusions: Based on results of this study, it can be concluded that work unit in COVID-19 isolation room had a relationship with sleep quality of shift nurses who work in the unit.

Este artigo pretende realizar uma análise sobre a relação entre a condição periférica latino-americana e o presente momento de retrocesso social vivenciado na região. Isto é, busca compreender o que há de específico na América Latina, enquanto periferia do sistema-mundo, que possibilita o avanço do autoritarismo e a redução de direitos. Para isso, utiliza a obra do teórico descolonial Aníbal Quijano para investigar as especificidades da democracia e dos Estados modernos latinoamericanos. É possível concluir, então, que referidas mazelas presentes na região estão correlacionadas tanto com a localização geopolítica quanto com o papel desempenhado pelas elites nacionais.Palavras-chave: América-Latina. Giro-decolonial. Colonialidade. Retrocesso social. Crise.ANÍBAL QUIJANO, SOCIAL REGRESSION AND CRISIS: the peripheral condition and the ailments of the present timeAbstractThis article intends to carry out an analysis of the relationship between the Latin American peripheral condition and the present moment of social regression experienced in the region.

PLURALISMO JURÍDICO COMO ALTERNATIVA EPISTEMOLÓGICA PARA A CULTURA DE DIREITOS HUMANOS DESDE O CONTEXTO LATINO-AMERICANO
Authors: Spinieli André Luiz Pereira 
Published: March 2021

O debate sobre o pluralismo jurídico no contexto político e social latino-americano não é recente, de modo que suas percepções foram renovadas a partir do movimento neoconstitucionalista operado no continente, responsável por desencadear alternativas epistêmicas para se pensar a efetividade dos direitos humanos e dos direitos de cidadania, tudo a partir da lógica de emancipação social e descolonialidade, como possibilidade de rompimento com o constitucionalismo tradicional, de cunho conservador, hegemônico e colonialista. Em termos gerais, como uma das respostas à concepção juspositivista, o pluralismo jurídico surge como modelo de pensamento para a práxis dos direitos humanos, em face de uma sociedade na qual impera a lógica das exclusões concretas em contrariedade às inclusões abstratas. Dessa forma, tomando por base a abordagem bibliográfica, este trabalho propõe oferecer reflexões a respeito do atual estado da cultura de direitos humanos instalada na América Latina, com enfoque nas contribuições epistemológicas advindas da teoria críticados direitos humanos e do pluralismo jurídico wolkmeriano.Palavras-chave: Pluralismo jurídico. Direitos humanos. Cultura constitucional. América Latina. Teoria crítica dos direitos humanos.LEGAL PLURALISM AS AN EPISTEMOLOGICAL ALTERNATIVE FOR THE CULTURE OF HUMAN RIGHTS SINCE THE LATIN AMERICAN CONTEXTAbstractThe debate on legal pluralism in the Latin American political and social context is not recent, so that their perceptions were renewed from the neo-constitutionalist movement operated on the continent, responsible for triggering epistemic alternatives to think about the effectiveness of human rights and human rights of citizenship, all based on the logic of social emancipation and decoloniality, as a possibility of breaking with traditional constitutionalism, of a conservative, hegemonic and colonialist nature. In general terms, as one of the answers to the juspositivist conception, legal pluralism emerges as a model of thoughtfor the practice of human rights, in the face of a society in which the logic of concrete exclusions prevails in opposition to abstract inclusions. Thus, based on the bibliographic approach, this work proposes to offer reflections on the current state of human rights culture in Latin America, focusing on the epistemological contributions arising from the critical theory of human rights and legal Wolkmer’s pluralism.Keywords: Legal Pluralism.
