Estrutura e compactação na permeabilidade de solos do Rio Grande do Sul
(1981) [Artículo de periódico]Os trabalhos de preparo do solo destroem a estrutura natural da camada arável e, se realizados sob condições de excesso de umidade, provocam compactação, que reduz as taxas de infiltração e aumentam o volume de escoamento ... -
Determination and characterization of the junction angles in river channels in Brazil with Google Earth Pro images
(2024) [Artículo de periódico]The determination of the junction angles and the river dynamics that form them have been studied since the 1930s. These studies normally have three approaches: reduced models, field investigation, and numerical simulation. ... -
Degradation of ampicillin by combined process : adsorption and Fenton reaction
(2022) [Artículo de periódico]When disposed incorrectly, antibiotics can cause complex effects on environmental matrices, such as bacterial resistance. In this context, the present work investigated the degradation and mineralization of the β-lactam ... -
Effect of chemical treatments on the mechanical properties of jute/polyester composites
(2024) [Artículo de periódico]Natural fiber composites have been extensively studied for structural applications, with recent exploration into their potential for various uses. This study investigates the impact of chemical treatments on the properties ... -
Integration of ozonation with water treatment for pharmaceuticals removal from Arroio Diluvio in southern Brazil
(2023) [Artículo de periódico]Pharmaceutical compounds can reach water bodies through sewage systems. The process of water treatment is insufficient for the removal of these contaminants. The ozonation has great potential to be integrated into the ... -
Effect of hybridization of carbon fibers on mechanical properties of cellulose fiber-cement composites : a response surface methodology study
(2024) [Artículo de periódico]Fiber-reinforced cement composites, particularly those incorporating natural fibers like cellulose, have gained attention for their potential towards more sustainable construction. However, natural fibers present inherent ... -
Avaliação de modelos de energia para simulação numérica do comportamento mecânico de multifilamentos de poliéster
(2023) [Artículo de periódico]Os sistemas de amarração feitos de cordas de fibra sintética e, em particular, os de poliéster, ganharam destaque nas últimas décadas. Porém o comportamento mecânico de tais fibras tem suas complexidades para simulação em ... -
Evaluation of residual strength of polymeric yarns subjected to previous impact loads
(2022) [Artículo de periódico]The discovery of oil fields in deep and ultra-deep waters provided an opportunity to evaluate theuse of synthetic ropes, complementarily or alternatively to traditional steel-based mooring lines inoffshore units, mainly ... -
Dynamic behavior and permanent indentation in S2-glass woven fabric reinforced polymer composites under impact : experimentation and high-fidelity modeling
(2024) [Artículo de periódico]This paper studies the behavior of S2-glass woven fabric reinforced polymer composite under low-velocity impact at 18–110 J energy. A macro-homogeneous finite element model for the prediction of their response is implemented, ... -
Impact of water absorption on the creep performance of epoxy/microcrystalline cellulose composites
(2024) [Artículo de periódico]Recently, considerable effort has been made to study cellulose/epoxy compos-ites. However, there is a gap when it comes to understanding the post-conditioning anomalous effect of moisture uptake on their mechanical ...
