Breve reflexão sobre a mídia televisiva
Authors: Alves Fábio Carlos Rodrigues , Andreatta Dulce Whitaker Consuello 
Published: April 2019

O presente artigo trata-se de uma análise sucinta sobre a mídia televisiva e sua cota de responsabilidade na perseguição política seletiva. Este artigo fora elaborado com base em pesquisa anterior denominada “Jornal Nacional um Caso de Amor com o Poder: Estudo de Adesão e Resistência à Ideologia do Grupo Globo em uma Cidade do Interior do Estado de São Paulo”, dos mesmos autores. Nesta pesquisa mais ampla, foram analisadas algumas reportagens do Jornal Nacional, como por exemplo as reportagens do Jornal Nacional sobre a substância fosfoetanolamina, e as matérias jornalísticas deste telejornal em relação aos ex-presidentes Luiz Inácio Lula da Silva e Dilma Vana Rousseff, sendo que concluímos por uma certa parcialidade do Jornal Nacional, seja para defender interesses de grandes anunciantes (corporações farmacêuticas, no caso das reportagens sobre a fosfoetanolamina), seja na perseguição política seletiva contra políticos do Partido dos Trabalhadores. Ademais, conforme os dados e entrevistas citados no bojo deste artigo (oriundos da análise de 300 questionários aplicados em 06 bairros da cidade de Araraquara/SP), chegamos a conclusões não terminativas, pois notamos que há um processo dialético: emissão hegemônica versus submissão/resistência da população.

Investigation of Gas Foil Bearings With an Adaptive and Non-Linear Structure
Authors: Żywica Grzegorz , Bagiński Paweł 
Published: April 2019

Abstract
The article discusses the results of simulation-based and experimental research carried out on gas foil bearings. Owing to the use of a set of flexible thin foils in such bearings, they exhibit certain beneficial features that cannot be found in other types of bearings. They have nonlinear operational characteristics and allow the dissipation of excess energy, thus reducing the vibration level. Moreover, gas foil bearings can self-adapt themselves to the current operating conditions by changing the shape of the lubrication gap. Therefore, they can be used to improve the dynamic performance of rotors, in particular, those operating at very high rotational speeds. This article explains the mechanisms for changes of stiffness and vibration damping in compliant components of a foil bearing. The results of the analysis of the bearing’s subassemblies using advanced numerical models are presented. They are followed by conclusions that were drawn not only from these results but also from the results of the experimental research. It has been proven that the rotor supported on carefully designed foil bearings is capable of maintaining a low vibration level, even if it operates at a high rotational speed.
Experimental Investigations of Elimination The Stick-Slip Phenomenon in The Presence of Longitudinal Tangential Vibration
Authors: Leus Mariusz , Abrahamowicz Marta 
Published: April 2019

Abstract
The article presents a scheme and description of the test stand as well as selected experimental results of the influence of longitudinal tangential vibrations on the stick-slip phenomenon. The tests were carried out at a constant forced vibration frequency f = 2000 Hz, as a function of the amplitude of the vibration velocity va
. The position of the sliding body and the drive force necessary to make the body slip and maintain this motion were measured. The measurements were made in two successive stages. In the first stage, when the substrate on which the sliding occurred was stationary. In the second one, the substrate is in a vibrating motion in the direction parallel to the slip. The conducted experimental analyses have shown that longitudinal tangential vibrations can contribute to the reduction or even complete elimination of the stick-slip phenomenon.

Published: April 2019

Abstract
By changing the air and water flow relative rates in the two-phase (air-water) flow through a minichannel, we observe aggregation and partitioning of air bubbles and slugs of different sizes. An air bubble arrangement, which show non-periodic and periodic patterns. The spatiotemporal behaviour was recorded by a digital camera. Multiscale entropy analysis is a method of measuring the time series complexity. The main aim of the paper was testing the possibility of implementation of multiscale entropy for two-phase flow patterns classification. For better understanding, the dynamics of the two-phase flow patterns inside the minichannel histograms and wavelet methods were also used. In particular, we found a clear distinction between bubbles and slugs formations in terms of multiscale entropy. On the other hand, the intermediate region was effected by appearance of both forms in non-periodic and periodic sequences. The preliminary results were confirmed by using histograms and wavelets.

Published: April 2019

Abstract
Three types of sintered alloys were fabricated based on cobalt, nickel and high-temperature alloy ZhS32-VI matrix with titanium carbide strengthening phase. TiC content was in a range of 30–50 vol. %. The melting temperatures of alloys are higher than 1320°C, and they may undergo undamaged through all technological procedures together with turbine blades, including soldering and outgassing. DSC analyses indicates no additional thermal effects until melting, which confirms their structural stability. The examinations of microstructure revealed three types of constituents – TiC particles, matrix solid solution and blow outs – structural defects having negative effects on all the studied properties. It was found that heat resistance of nickel based sintered alloys at the temperature of 1100°C is superior as compared with the alloys based on cobalt and alloy ZhS32-VI. It has been established that wear resistance in conditions of fretting wear at temperatures of 20, 850, 950 and 1050°C of sintered alloy with ZhS32-VI matrix is mostly superior as compared with the other alloys. The properties of produced alloys allow to use them for manufacturing of components of friction couples operating in conditions of high temperature fretting wear, including protective pads of turbine blades top shrouds contact faces.

Authors: Kukuła Karol 
Published: April 2019

Summary

Subject and purpose of work: The article presents research aimed at creating the ranking of provinces due to the degree of environmental pollution. The presentation of the spatial distribution of pollutants should result in taking appropriate pro-ecological actions in the provinces.

Materials and methods: Secondary material included in the research was the publication entitled “Environmental Protection – Environment 2017” by the Central Statistical Office. The method of ranking diagnostic variables was applied and then a synthetic variable determining the level of pollution in individual provinces was constructed, which made it possible to create their ranking. In the final stage, the author’s own method was implemented in order to divide the provinces into 3 groups.

Results: The provinces were ranked from a relatively little to very polluted ones. Three groups of provinces were distinguished according to the criterion discussed. It has been revealed that the third group with the highest degree of environmental contamination includes as many as 8 provinces, that is half of them.

Conclusions: The author believes that in order to prepare a more precise spatial diagnosis of the state of the natural environment in Poland, research has to be extended by including adequate information at the county level.

Authors: Kościk Bogdan , Kowalczyk-Juśko Alina , Borecka Renata , Kielmas Krzysztof 
Published: April 2019

Summary

Subject and purpose of work: The work concerns the reduction of greenhouse gas emission thanks to renewable energy sources (RES) utilized in selected municipalities of the Lubelskie Province. The aim of the study was to assess the consistency between the tasks provided in low-emission economy plans (LEEP) and the strategic documents on RES, especially biomass. The investment priorities of municipalities regarding RES and the impact of these investments on the emission of CO2 have been presented.

Materials and methods: The analysis covered 8 LEEPs and programming documents: EU, national and regional ones concerning RES.

Results: EU and Polish policy contribute to the development of RES, including biomass, under the condition that their negative effect on the environment, resulting especially from biomass burning, is limited. Municipalities intend mainly to use solar energy, yet the technologies of biomass they suggest are not always in line with new trends.

Conclusions: Measures limiting the emission of greenhouse gases, including the use of RES, are provided in the analysed LEEPs. However, some municipalities intend to produce energy from biomass, mainly in the process of combustion. As this is not in line with the latest EU recommendations, such plans should then be verified.

The Fall of the Queen of Nordic Skiing: A comparative analysis of the Swedish and Norwegian media coverage of the Therese Johaug scandal
Authors: Wagner Ulrik , Kristiansen Elsa 
Published: April 2019

Abstract
In 2016, Norwegian cross-country skier Therese Johaug made her positive doping test public. We compare how the Norwegian and Swedish media covered the ensuing scandal with the aim of discovering how constructions of subjectivity, national identity, anti-doping policy and the role of cross-country skiing are interrelated. Drawing on a critical discourse analytical research design, we identify significant differences: the Norwegian media hesitated to call it a doping scandal and occasionally portrayed Johaug as a victim, whereas the Swedish media provided a platform for harsh criticism of the Norwegian’s use of medicine and emphasised the individual responsibility of the athlete. Thus, this study elucidates how sport is mediated as part of a national rivalry between two Scandinavian countries that are both heavily engaged in cross-country skiing.

Descolonizar e interculturalizar el saber: el reto de la universidad latinoamericana.
Authors: Galarza López C. Gabriel , Salazar Alba 
Published: April 2019

Varios intelectuales latinoamericanos, en los últimos años, vienen reflexionando acerca de lo que ha significado y lo que aún significa en la actualidad, para América Latina y el Caribe la modernidad generada en Occidente y la cara oculta de la colonialidad. Entre ellos, consideramos que Aníbal Quijano constituye un referente que vigoriza el pensamiento crítico latinoamericano, a partir de la teoría de la colonialidad del poder. Mediante la deconstrucción histórica devela la existencia de un patrón de poder de dominación social que se engendra en el siglo XVI con la conquista y colonización, cuyas ideas se han prolongado hasta nuestros días. La idea de raza es un constructo mental que viene operando eficazmente como mecanismo de subalternidad y exclusión de grupos humanos, así como el patriarcado, la hegemonía cultural y el uso indiscriminado de la naturaleza para sobreexplotarla y degradarla. Todo ello para saciar la voracidad del capitalismo.

Cuestionamientos y alternativas de respuesta al desarrollo y su expresión local
Authors: Riera Vázquez C. Celia M , Fabré Machado Idalsis 
Published: April 2019

Repasando los asideros conceptuales y metodológicos de las diversas adjetivaciones dadas al desarrollo, es ostensible la ausencia de una formulación conceptual que denote y connote el carácter esencialmente contradictorio del proceso mismo. Se pasa por alto que dicha contradicción, es condición necesaria para la existencia, movimiento y transformación de cualquier sistema y, por tanto, cuando se habla de desarrollo se impone destacar que su contradictoriedad se ancla en el proceso de enajenación social y la potencialidad de este estado para transformarse en su contrario. Trabajo vs capital media la comprensión y las apuestas por el desarrollo. Tal reconocimiento sitúa al desarrollo y su expresión localen la concepción que centra y enfatiza la idea de autodesarrollo articulado con lo comunitario, núcleo de la comprensión marxista de la sociedad y la historia. Co-responsablesde diseminartal reconocimiento son los intelectuales y profesores desde las cátedras, los espacios de asesoramiento, de monitoreo y decisores.
THE EFFECT OF FINANCIAL LEVERAGE ON DEBT REPAYMENT CAPACITY : EVIDENCE FROM LISTED SHIPPING COMPANY IN INDONESIA
Authors: Setiawan Danu Ade 
Published: April 2019

Contrast with its potentiality in the largest Archipelago country on the world, shipping industry in Indonesia show unsatisfactory condition whereas its industry’s national growth is below the overall industries growth and industry’s non-performing loan (NPL) rate is higher than national NPL. This condition is caused by the nature of the shipping industry with a high level of business uncertainty and their liability’s structure are dominated by banks and other financial institutions’ long-term debts. This research examines the relationship between financial leverage variable on the debt repayment capacity variable specifically to the banks and other financial institutions. The research population is shipping companies listed in Indonesia stock exchange with a number of samples is 12 companies. The consolidated financial statements in the period between 2014 and 2015 from the selected sample are used in this research. Based on literature review, the variable of company’s leverage is represented by a debt-equity ratio (DER). On the debt repayment capacity variable, the qualitative research method that is Delphi method is applied to define the ratio represented the variable. As the result, the debt repayment capacity variable is represented by Debt Security Coverage Ratio (DSCR). The statistical method that is used in this research is correlation analysis. Correlation analysis is a group of techniques to measure the relationship between two variables that are financial leverage represented by DER and debt repayment capacity represented by DSCR. The result shows that there is a negative correlation between financial leverage that is represented by DER and debt repayment capacity that is represented by DSCR. However, the correlation between them is considered weak with Pearson correlation coefficient less than 0,5 in absolute value or the influence of DER to the DSCR is insignificant.
