1. MICROPLÁSTICOS: USO NA INDÚSTRIA COSMÉTICA E IMPACTOS NO AMBIENTE AQUÁTICO
Environmental pollution from plastics and microplastics is currently one of the most relevant issues of the scientific community and cosmetic industry. In particular, microplastics are referred to as small pieces of plastic less than five millimeters (<5mm) and do not dissolve in water, can be harmful to the ocean and aquatic life. Microplastics can be desig

2. Vestibular System Eletrophysiology: An Analysis of the Relationship between Hearing and Movement
Abstract Introduction Knowledge about the positive effects that music and dance bring, in its various forms, to the healthy human brain, is important not only in the context of basic neuroscience but may also strongly affect practices in neurorehabilitation. Objective To verify the relationship between hearing and movement and, specifically, to analyze the

3. Characterization of Sobradinho landslide in fluvial valley using MASW and ERT methods
Abstract Landslides can substantially impact the fluvial systems, which is why the continuous mapping of their extent, evolution and stability assessment is crucial. However, in such environments, material identification (e.g. colluvium) and subsurface characterization by the methods used for geologic mapping and geotechnical investigation is often a challen

4. Error Analysis of the Numerical Method for Correcting the Propagation of EM waves in the Troposphere
Abstract Electromagnetic (EM) waves do not travel in straight lines in the troposphere due to refraction. This leads to errors in many engineering applications. In order to correct these errors, a numerical solution based on the difference method has been proposed, which can reveal the degree of EM wave bending owing to atmospheric refraction, moreover, it c

5. Seismic signature of mudflow tremor resulted from Brumadinho (Brazil) tailings dam failure
Abstract Mudflow is often associated with seismic activities. The present study applied a seismic based detection of the surface waves generated by the mudflow of Brumadinho dam collapse using records of Brazilian Seismographic Network. The signal envelope and time-frequency spectrograms of the mudflow signals were used in the analysis. As a result, the mudf

6. Geospatial analysis of the effects of tsunami on coral and mangrove ecosystems of Mayabunder in Andaman Islands, India
Abstract Mangroves and coral reefs are among the major ecosystems of tropical and subtropical coastlines. The Andaman group of islands, situated at the juncture of Bay of Bengal and Indian Ocean, are one of the richest coastal ecosystems of India in terms of biodiversity. Since the tsunami waves of 2004 affected this region severely, the outer fringes as wel

7. Frequency-Following Response with Speech Stimulus: Comparison between Two Methods of Stimulation
Abstract Introduction Frequency-following response with speech stimulus (FFR-speech) is a subcortical potential that satisfactorily evaluates the processing of verbal information. However, there still are differences in the literature regarding its analysis and stimulation protocol. Objective To compare two stimulation protocols for the capture of FFR-sp

8. Analysis of physical mechanisms of human body instability for the definition of hazard zones present in emergency action plans of dams. Case study: Santa Helena Dam, Bahia
RESUMO Os impactos produzidos pelas ondas de cheias decorrentes de ruptura de barragens geralmente causam danos irreversíveis à população residente e a perda do equilíbrio do corpo nas inundações contribui para o agravamento desse cenário. Nesse contexto, esse trabalho teve como objetivo analisar a influência da consideração dos mecanismos físico

9. Evaluación del entendimiento de ondas mecánicas utilizando un test de opción múltiple en español
Abstract The “Mechanical Waves Conceptual Survey (MWCS)”, is the most important multiple-choice test designed to date to evaluate the understanding of university students in four themes of mechanical waves: propagation, superposition, reflection, and standing waves. In this study, we present a significant modification of this test in Spanish. We administ

10. Simulador didático para análise dos transientes de ondas de tensão em uma linha de transmissão similar à transmissão e reflexão de ondas eletromagnéticas
Abstract O modelo de educação nas últimas décadas passou por mudanças consideráveis do ponto de vista didático. Com o avanço da tecnologia, a velocidade de obtenção de informações aumenta e o uso de ferramentas que permitem a visualização dinâmica de conteúdos torna-se um forte aliado ao processo de ensino-aprendizagem. Este trabalho trata da

11. Salud pública, espacio urbano y exclusión social en la España de posguerra: la epidemia de tifus exantemático en la ciudad de Valencia, 1941-1943
Abstract After the Spanish Civil War, poor hygiene and nutritional deficiencies among a large part of Spain’s population contributed to the rise of epidemic diseases. Exanthematic typhus posed a challenge to the health authorities, especially during the spring of 1941, when the epidemiological cycle of the disease and the lack of infrastructures combined t

12. Leitura do institucionalismo organizacional a partir da teoria do organizar de Karl Weick
Resumo O objetivo central deste artigo é evidenciar as possibilidades de uso da teoria do organizar de Karl Weick como microfundamento para o institucionalismo organizacional, considerando que essa abordagem da ação se mostra mais adequada do que aquelas predominantes nos estudos institucionalistas. Partindo do pressuposto de que a ação em organizaçõe
