Abstract Latin America and Caribbean (LAC) regions were an important epicenter of the COVID-19 pandemic SARS-CoV-2 evolution. Through Genomic Surveillance Regional Network (COVIGEN), LAC countries produced number genomic sequencing data that made possible enhanced surveillance capacity in Americas, paving way for characterization emerging variants helping to guide public health response. In this study we analyzed approximately 300,000 sequences generated between February 2020 March 2022 by...
Abstract The lichen, Punclelia subrudecta (Ny1.) Krog., was transplanted to 10 biomonitoring sites during the period December 1990-March 1991. total amounts of metals (Mn, Cu, Pb, Zn, Fe and A1) detected in lichen thalli after exposure, were compared with chlorophyll degradation, sulphur, MDA concentrations soluble protein same material. content directly related amount sulphur A contamination index (C.I.) calculated from chlorophyll-α, phaeophytin-α, MDA.
Ramalina celastri was used as a passive biomonitor to study the relationship between elemental accumulation, emission sources and physiochemical parameters air pollution biomarkers in Argentina. The concentration of 27 elements determined thalli by Neutron Activation Analysis (NAA). content photosynthetic pigments, peroxidation products, water sulphur Pollution Index (PI) calculated. Factor analysis locate possible elements. Overall, concentrations were similar other biomonitoring studies....
The lichen Ramalina celastri was employed as an in situ biomonitor for the study of air quality and heavy metal distribution central region Argentine Republic. thallus content copper, iron, manganese, cobalt, zinc, nickel lead determined by atomic absorption spectrophotometry. Pigments, hydroperoxy conjugated dienes, malondialdehyde sulfur were also measured. Some these parameters used to calculate a pollution index. Geographical patterns obtained different metals mapping. Thus, zinc shows...
Lichen Ramalina ecklonii (Spreng.) Mey. & Flot. was transplanted to 20 biomonitoring sites in an urban‐industrial region including a power station. Pigments, hydroperoxy conjugated dienes, malondialdehyde, soluble protein and sulphur were quantified the lichen samples. A pollution index calculated, based on certain chemical parameters. The established according environmental conditions, such as traffic, industries distance from Chemical responses associated with street traffic changes...
Abstract The placement of multiple fractures in horizontal, deviated wells is usually more difficult than vertical wells. When completed with uncemented preperforated liners, such treatments become much and often are ineffective using conventional stimulation methods. found offshore locations, these present even problems. Recently, the shallow waters Brazil, a relatively new hydrajetting technology was used great success. However, additional complications arose when hydrajet fracturing...
