1. SIMULATING THE EFFECT OF PERMANENT PRESERVATION AREAS ON SOIL EROSION RATES
ABSTRACT Water erosion is one of the main problems faced by the Furnas Lake Surrounding Watershed, located in southeast Brazil. The erosive process is intensified by inadequate land occupation of the lake margins where should be riparian forests, or permanent preservation areas (APP), in order to protect water resources. In this context, our work aimed to es

2. Erosion of the nocturnal boundary layer in the central Amazon during the dry season
RESUMO Este estudo teve como objetivo analisar a erosão da camada limite noturna (CLN) na Amazônia central durante a estação seca de 2014, usando dados do Projeto GoAmazon 2014/5 e saídas do modelo de alta resolução (PArallelized Les Model - PALM). O conjunto de dados consistiu de medidas por instrumentos in situ (radiossonda) e sensoriamento remoto (

3. Numerical Simulation of Debris Flows of the Catastrophic Event of February 2019 in Mirave - Peru
Resumo Os fluxos de detritos são fenômenos geofísicos provocados por chuvas torrenciais, que ocorrem em áreas montanhosas, e se caracterizam pelo desprendimento de materiais de declives e de leitos de rios e seu consequente arraste água abaixo através de bacias e córregos. Os fluxos de detritos carregam consigo, em geral, lodo, água e rochas, e podem

4. Developing a Mathematical Model for the Controlled Release Over Time of Sulfentrazone Herbicide from Biodegradable Polymer
In our research group, controlled release systems for the sulfentrazone herbicide has been accomplished by encapsulating this bioactive compound into calcium alginate (Ca-ALG) biodegradable polymer fashion and the release mechanisms were verified by using Korsmeyer-Peppas model (KP). However, the KP model does not allow to evaluate all the phenomena involved

5. Assessing Water Erosion Processes in Degraded Area Using Unmanned Aerial Vehicle Imagery
ABSTRACT The use of Unmanned Aerial Vehicles (UAVs) and Structure from Motion (SfM) techniques can contribute to increase the accessibility, accuracy, and resolution of Digital Elevation Models (DEMs) used for soil erosion monitoring. This study aimed to evaluate the use of four DEMs obtained over a year to monitor erosion processes in an erosion-degraded ar

6. Effect of Incudostapedial Reconstruction Using Conchal Cartilage Interposition Graft on Hearing Outcome
Abstract Introduction Chronic otitis media is a widely prevalent condition in developing countries and is a cause of correctable hearing loss. The most frequent ossicular chain defect found during surgery for chronic otitis media has been a discontinuity of the incudostapedial joint. This study observes the effect of incudostapedial reconstruction using co

7. Surface sealing and water erosion of soils with mulching in the semi-arid region of Brazil
RESUMO A avaliação do processo de selamento superficial em solos da região semiárida Brasileira é de grande relevância para compreensão do processo e tomada de medidas mitigatórias. Objetivou-se avaliar o selamento superficial e características físico-hídricas dos principais solos da Bacia Representativa do Alto Ipanema, Pesqueira-PE, sob influên

8. Mass balances of major solutes, nutrients and particulate matter as water moves through the floodplains of the Pantanal (Paraguay River, Brazil)
RESUMO Na Bacia do Alto Paraguai, formadora do Pantanal Mato-grossense, uma das maiores áreas úmidas do mundo, os rios fazem a conexão entre o planalto e a extensa planície de inundação. Agropecuária, potencial erosivo associado a desmatamento elevado, efluentes urbanos e dezenas de barramentos hidrelétricos no planalto podem alterar o transporte de

9. Losses of soil, water, organic carbon and nutrients caused by water erosion in different crops and natural savannah in the northern Amazon
Resumo Atualmente no Brasil a principal forma de erosão é causada pelo impacto das gotas de chuva na superfície do solo, desencadeando o processo de erosão hídrica e causando sérios danos às áreas agrícolas. Este trabalho foi realizado com o objetivo de avaliar perdas de solo, água, nutrientes e carbono orgânico em diferentes culturas, solo descob

10. Forage sorghum-legumes intercropping: effect on growth, yields, nutritional quality and economic returns
ABSTRACT Cereal-legumes intercropping is among the most economical and effective agronomic strategies to boost forage biomass production, nutritional quality and monetary returns. This review synthesizes the research findings on how intercropping affects productivity, quality, competitiveness and economic viability of sorghum-legumes mixed, row and strip int

11. Numerical Studies of Penetration in Light Armor, Concrete and Brick-Wall Targets
ABSTRACT The accurate numerical simulation of projectile penetration process is a complex challenge. Experimental investigation of these time-dependent non-linear events is expensive and time-consuming. In this paper, 3-D numerical simulations are carried out to estimate the penetration performance of designed penetrators against the double and triple brick-

12. Morphology and morphometry of upland lakes over lateritic crust, Serra dos Carajás, southeastern Amazon region
ABSTRACT High-resolution satellite images, digital elevation models, bathymetric and sedimentological surveys coupled with statistical analysis were used to understand the physical environment and discuss their influence on water quality of the five upland lakes of Serra Sul dos Carajás, southeast Amazonia. The lakes have mid-altitude ranges (elevation), ve
