13. Lago Guaíba: uma análise histórico-cultural da poluição hídrica em Porto Alegre, RS, Brasil
RESUMO A qualidade de vida é intrinsecamente ligada à disponibilidade de água, e a poluição desse recurso afeta diretamente as populações. O Lago Guaíba possui importância histórica, econômica e cultural para Porto Alegre (RS) e região metropolitana. Este trabalho discute o contexto histórico-cultural da poluição do Lago Guaíba. Com grande re

14. FOTOCATÁLISE MEDIADA POR TiO2 NO ESTADO NANOPARTICULADO: REVISÃO DA REATIVIDADE PELO CONCEITO DE TRAPS E ALGUMAS APLICAÇÕES EM QUÍMICA ANALÍTICA
TiO2 has been used as a white pigment and studied since the first decades of the XX century for the undesirable chalking of outdoor paintings exposed to sunlight. Since the first report of Honda and Fujishima (1972) of the water splitting by the harvesting of sunlight on a n-type single crystal TiO2 electrode, the engagement of researchers with the field has

15. Biomass smoke COPD has less tomographic abnormalities but worse hypoxemia compared with tobacco COPD
Special attention has emerged towards biomass smoke-induced chronic obstructive pulmonary disease (COPD), providing new knowledge for prevention and therapeutic approach of non-smoker COPD patients. However, the understanding of biomass smoke COPD is still limited and somewhat controversial. The aim of the present study was to compare COPD exclusively caused

16. Stream macroalgal flora from Parnaíba River Basin, Brazil: reducing Wallacean shortfall
Resumo: A perda de biodiversidade é um consenso. Os déficits de conservação tornam a conservação da diversidade biológica ainda mais desafiadora. Para muitos táxons, o conhecimento sobre suas distribuições é escasso, o que é chamado de Déficit Wallaceano. Essa situação não é diferente quando tratamos da biodiversidade de algas, especialmente

17. Nyssorhynchus dunhami: bionomics and natural infection by Plasmodium falciparum and P. vivax in the Peruvian Amazon
BACKGROUND Nyssorhynchus dunhami, a member of the Nuneztovari Complex, has been collected in Brazil, Colombia, and Peru and described as zoophilic. Although to date Ny. dunhami has not been documented to be naturally infected by Plasmodium, it is frequently misidentified as other Oswaldoi subgroup species that are local or regional malaria vectors. OBJECTIVE

18. Occurrence of Yeast Species in Soils under Native and Modified Vegetation in an Iron Mining Area
ABSTRACT Soils of the Quadrilátero Ferrífero are rich in mineral resources, especially gold and iron. Soil management and mining activities greatly impact soil biology. However, studies addressed to the diversity of microorganisms and their ecological role in the recovery of these areas are scarce. This study aimed to assess the yeast occurrence in soils w

19. ÉTERES DIFENÍLICOS POLIBROMADOS (PBDE) COMO CONTAMINANTES PERSISTENTES: OCORRÊNCIA, COMPORTAMENTO NO AMBIENTE E ESTRATÉGIAS ANALÍTICAS
Flame retardants are substances mixed with numerous materials to inhibit the combustion process, reducing risks and damages caused by fires. Among these substances, polybrominated diphenyl ethers (PBDEs) have been widely used for decades due to their low cost and high efficiency. However, since they are mixed and not chemically bonded to the materials, PBDEs

20. Evaluation of the Sustainability of Integrated Hydrothermal Synthesis of Zeolites Obtained from Waste
The high Si and Al contents in the amorphous phase of coal fly ash have been used for its conversion into zeolites. This process converts a toxic low-value by-product into a product used in a number of environmental applications, but has the disadvantage of introducing contaminants. Despite the large number of studies on the conversion of fly ash into zeolit

21. Molecular screening of blue mussels indicated high mid-summer prevalence of human genogroup II Noroviruses, including the pandemic "GII.4 2012" variants in UK coastal waters during 2013
Abstract This molecular study is the first report, to the best of our knowledge, on identification of norovirus, NoV GII.4 Sydney 2012 variants, from blue mussels collected from UK coastal waters. Blue mussels (three pooled samples from twelve mussels) collected during the 2013 summer months from UK coastal sites were screened by RT-PCR assays. PCR products

22. Leaf-associated bacterial microbiota of coffee and its correlation with manganese and calcium levels on leaves
Abstract Coffee is one of the most valuable agricultural commodities and the plants’ leaves are the primary site of infection for most coffee diseases, such as the devastating coffee leaf rust. Therefore, the use of bacterial microbiota that inhabits coffee leaves to fight infections could be an alternative agricultural method to protect against coffee dis

23. Range extension to Santo Domingo de los Tsáchilas province and revised distribution of Platyrrhinus chocoensis (Phyllostomidae: Chiroptera) in western Ecuador
Abstract We report the first record of the Choco broad-nosed bat (Plathyrrhinus chocoensis Alberico & Velazco, 1991) in Santo Domingo de los Tsáchilas province in northwestern Ecuador. This voucher specimen represents the southernmost record of the species and expands its distribution ca. 120 km south. The animal was caught at a farm, specifically in a live

24. Draft genome sequence of Exiguobacterium aurantiacum strain PN47 isolate from saline ponds, known as “Salar del Huasco”, located in the Altiplano in the North of Chile
ABSTRACT In this report, we present a draft genome of 2,886,173 bp of an Exiguobacterium aurantiacum strain PN47 isolate from the sediment of a saline pond named “Salar del Huasco” in the Altiplano in the North of Chile. Strain PN47 encodes adaptive characteristics enabling survival in extreme environmental conditions of high heavy metal and salt concent
