Cyanogenic Compounds, Physicochemical Parameters and Metals in Water From Cassava Processing Areas: A Study in the Brazilian Amazon, Using Multivariate Analysis

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT This study evaluated the water quality of artesian wells and effluents generated in cassava processing in a rural area of Bragança, Pará, with emphasis on physicochemical parameters, multielement composition, and cyanogenic compounds. The well water presented specific nonconformities, highlighting pH values below the recommended level and high

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...

Coarse‐Grained Molecular Dynamics Simulations of Oxidative Aging and Stabilization in Polymer Melts With Primary Antioxidants: Effects of Antioxidant Concentration and Molecular Architecture

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
Antioxidant type and concentration govern both the rate and spatial heterogeneity of oxidative aging in polymer melts. Higher antioxidant‐group concentration prolongs the induction and reaction time scales, while the BHT‐type antioxidant provides stronger and more homogeneous stabilization than the Irganox1010‐type antioxidant because of its more ...

Integration of Micro‐CT and XRF Mapping for Multimodal 3D Analysis of Polychrome Wooden Artifacts

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT Over the past 5 years, computer applications have become crucial to archeological research. Since the 1990s, the focus has transitioned from data management tools to the development of virtual models. Recently, digital documentation of cultural heritage has gained considerable focus, with 3D modeling of objects.

The industrial and cultural heritage in landscape: Industrial Heritage, Landscape, Intelligent Territory

open access: yes, 2010
Scenic values, industrial traces and artistic heritage are intertwined in a continuous space. IndustrialHeritage has acquired a meaning beyond the aesthetic or testimonial to become a spatial or temporalcore face of forgetfulness and loss of place memory. The “smartplaces”, where active communitieslive, are or were able to organize themselves to design
