Numerical simulation of a submerged circular turbulent jet impinging on flat and eroded boundaries
(CRC PRESS/BALKEMA, 2016-07-11)
Soil erosion may degrade water quality, cause riverbank instability, and damage infrastructure. Cohesive soil erosion is a complex process that depends on the physical, chemical and biological properties of soil as well ...
Analysis of the bond interface between self-adhesive resin cement to eroded dentin in vitro
(2018-11-01)
The purpose of this study was to evaluate the bonding interface between a self-adhesive resin cement to in vitro eroded dentin. Seventy-two third molars were used and divided into two groups: sound dentin and in vitro ...
DETERMINATION OF SOIL ERODIBILITY BY MEANS OF TWO INDIRECT METHODS IN A WATERSHED IN THE SOUTHERN REGION OF THE STATE OF AMAZONAS, BRAZIL
(Uniao Geomorfologia Brasileira, 2020-04-01)
Water erosion is one of the main problems facing agriculture worldwide. It is responsible for the transport of sediments that compromise the quality and quantity of water in rivers and reservoirs, as well as for the loss ...
Changes in soil organic matter associated with afforestation affect erosion processes: The case of erodible volcanic soils from Patagonia
(Elsevier Science, 2021-12)
Large areas of the Patagonian Andean Region with high potential for planting fast-growing exotic conifers, based on the volcanic nature of its soils, are affected by erosion processes. This study aimed to analyse the effects ...
Changing mountain farmscapes: vulnerability and migration drivers in the Paute River watershed, Southern Ecuador
(2021)
Abrupt changes in land use/land cover have often characterized Andean rural landscapes. This is particularly notorious in the Paute River watershed in southern Ecuador. We seek to show how, under tenets of the global ...
Enzymatic, morphological, and genotoxic effects of benzo[a]pyrene in rainbow trout (Oncorhynchus mykiss)
(2021-01-01)
Fish have defense systems that are capable of repairing damages caused by xenobiotics like benzo[a]pyrene (BaP), so the aims of this study were to identify BaP toxicity in melanomacrophages (MMs) cytoskeleton, evaluate the ...
Soil erodibility assessment in a pasture and forest remnant using the inderbitzen device
(2013-05-28)
Brazil has the largest cattle herd in the world with approximately 200 million head. An important feature of the Brazilian cattle industry is that most of its herd is raised on pasture, which constitutes one of the most ...
