Produção de sedimentos pela erosão em entressulcos em três Latossolos do Rio Grande do Sul Interrill soil erosion sediment yield on three Oxisols from Rio Grande do Sul state, Brazil

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental, 2011
A distribuição de diâmetro do sedimento produzido pela erosão hídrica dependerá do tipo e da textura do solo. Este trabalho foi desenvolvido com o objetivo de avaliar a distribuição de tamanho de sedimentos produzidos por erosão em entressulcos, em três ...

Dripping Rainfall Simulators for Soil Research—Design Review

open access: yesWater, 2022
Dripping rainfall simulators are important instruments in soil research. However, a large number of non-standardized simulators have been developed, making it difficult to combine and compare the results of different studies in which they were used. To overcome this problem, it is necessary to become familiar with the design and performances of the ...

Biobased Bionic Spider Silk via Electrostatic Complexation for Simultaneously Harvesting Atmospheric Water and Triboelectric Energy

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐based bionic spider silk and spider web are first prepared using polyelectrolyte complexation technique for the simultaneous harvesting of water and triboelectric energy. The advantage of this process lies on entirely bio‐based materials, fully green water‐processable procedures, extremely high production rate (99.36%), excellent fog harvesting ...

Were rivers flowing across the Sahara during the last interglacial? Implications for human migration through Africa. [PDF]

open access: yes, 2013
Human migration north through Africa is contentious. This paper uses a novel palaeohydrological and hydraulic modelling approach to test the hypothesis that under wetter climates c.100,000 years ago major river systems ran north across the Sahara to the ...

Metal–Organic Frameworks for Gaseous Pollutant Management: From Capture to Neutralization and Reutilization

open access: yesAdvanced Functional Materials, EarlyView.
This review maps how MOFs can manage hazardous gases by combining adsorption, neutralization, and reutilization, enabling sustainable air‐pollution control. Covering chemical warfare agent simulants, SO2, NOx, NH3, H2S, and volatile organic compounds, it highlights structure‐guided strategies that boost selectivity, water tolerance, and cycling ...

Efeito de escarificação e da erosividade de chuvas sobre algumas variáveis de valores de erosão hídrica em sistemas de manejo de um nitossolo háplico Effect of chiseling and rainfall erosivity on some characteristics of water erosion in a nitosol under distinct management systems

open access: yesRevista Brasileira de Ciência do Solo, 2008
O preparo do solo altera as suas condições físicas de superfície e subsuperfície e, conseqüentemente, influencia os valores de propriedades que se relacionam com a erosão hídrica.

Automated rainfall simulator for variable rainfall on urban green areas [PDF]

open access: yesHydrological Processes, 2019
AbstractRainfall simulators can enhance our understanding of the hydrologic processes affecting the total runoff to urban drainage systems. This knowledge can be used to improve urban drainage designs. In this study, a rainfall simulator is developed to simulate rainfall on urban green surfaces.

Predicting floods in a large karst river basin by coupling PERSIANN-CCS QPEs with a physically based distributed hydrological model [PDF]

open access: yes, 2019
In general, there are no long-term meteorological or hydrological data available for karst river basins. The lack of rainfall data is a great challenge that hinders the development of hydrological models. Quantitative precipitation estimates (QPEs) based

Compression‐Tension‐Asymmetry and Stiffness Nonlinearity of Collagen‐Matrigel Composite Hydrogels

open access: yesAdvanced Healthcare Materials, EarlyView.
Self‐assembled collagen hydrogel matrices are widely used in tissue engineering applications. These matrices stiffen and contract laterally under tension due to fiber alignment and soften and collapse under compression due to fiber buckling. It is demonstrated that filler materials, such as Matrigel, linearize the mechanical behavior of collagen ...

Restauração da estrutura do solo por sequências culturais implantadas em semeadura direta, e sua relação com a erosão hídrica em distintas condições físicas de superfície Restoration of the soil structure by crop sequences established in no-till, as related to water erosion in distinct surface physical conditions

open access: yesRevista Brasileira de Ciência do Solo, 2010
A estrutura do solo desempenha papel de destaque no crescimento de plantas e no controle da erosão e, por conseguinte, na produção de alimentos e na conservação do solo e da água. Considerando isso, realizou-se este trabalho com o objetivo de implementar
