COVID-19 Next Day Trend Forecast

Historically, weather conditions are depicted as an essential factor to be considered in predicting variation infections due to respiratory diseases, including influenza and Severe Acute Respiratory Syndrome SARS-CoV-2, best known as COVID-19. Predicting the number of cases will contribute to plan human and non-human resources in hospital facilities, including beds, ventilators, and support policy decisions on ...

Competition among rare earth elements on sorption onto six seaweeds

Sorption has been proposed as a promising approach towards a sustainable water decontamination and recently to the recycling of rare earth elements (REE). Although living seaweed have been shown to be capable of removing REE from contaminated solutions, no studies have yet compared the effects of REE competition on sorption onto different groups of seaweed. These effects were analysed in the present study by ex...

Does salinity variation increase synergistic effects of triclosan and carbon na...

The use of carbon nanotubes (CNTs) is rapidly increasing and several scientific studies have addressed their toxicological properties. However, only a very small number of publications have deal with the interaction between CNTs and other molecules. Triclosan (TCS) is an antibacterial agent used in personal care and household products. Commonly detected in aquatic ecosystems, there is a strong evidence that aqu...

Ecotoxicological effects of lanthanum in Mytilus galloprovincialis: biochemical...

Inappropriate processing and disposal of electronic waste contributes to the contamination of aquatic systems by various types of pollutants such as the rare-earth elements (REE) in which lanthanum (La) is included. Knowledge on the toxicity of these elements in marine organisms is still scarce when compared to other metals such as mercury (Hg) and arsenic (As). Therefore, this study aims to assess the toxicity...

The influence of temperature and salinity on the impacts of lead in Mytilus gal...

Mussels, such as the marine bivalve Mytilus galloprovincialis are sentinels for marine pollution but they are also excellent bioindicators under laboratory conditions. For that, in this study we tested the modulation of biochemical responses under realistic concentrations of the toxic metal Lead (Pb) in water for 28 days under different conditions of salinity and temperature, including control condition (temper...

PHYSICAL EDUCATION AND THE “CULTURALIST TURNAROUND” OF THE FIELD: A VIEW BASED ...

This paper discusses the “culturalist dilemma” in the field of Physical Education in Brazil under the perspective of two important authors: Mauro Betti and Valter Bracht. Propositions of culturalist nature were very important for the field because, in addition to providing various epistemological advances, they supported the construction of several curriculum guidelines in Brazil. After characterizing the dilem...

Custos ecológicos e sustentabilidade em recursos hídricos na indústria têxtil

Methodology of a nationwide cross-sectional survey of prevalence and epidemiolo...

Um inquérito de base populacional foi conduzido na população urbana de todas as capitais e do Distrito Federal no Brasil para fornecer informações sobre a prevalência de hepatites virais e fatores de risco, entre 2005 e 2009. Este artigo descreve o delineamento e a metodologia do estudo que envolveu a população com idade entre 5 e 19 anos para hepatite A e 10 a 69 anos para hepatite B e C. As entrevistas e amos...
