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

Environmental aspects of soil phosphorus testing [PDF]

open access: yes, 2005
peer-reviewedSoil phosphorus testing in Ireland uses Morgan’s reagent from samples taken to 10 cm depth for agronomic recommendations. However, its suitability as an environmental indicator has been questioned in terms of sample depth and extraction ...

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Pyramidal Structures on Yttria‐Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material

open access: yesAdvanced Engineering Materials, EarlyView.
New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Nitrogen and Phosphorous Loss as Affected by Plough Direction in Rainfed Wheat Land of a Semi- Arid Region

open access: yesعلوم آب و خاک, 2020
Sloping farmlands are the major sources of soil, water and nutrient losses in arid and semi-arid regions. Information about the impacts of different tillage practices on soil erosion, nutrient loss and crop nutrient uptake on the sloping farmland of semi-

Impacts of climate change on erosion of a watershed: Simulation of scenarios

open access: yesRevista Ambiente & Água, 2011
Climate change set to occur in the coming years should have severe effects on erosion process, as factors leading to intensification of the peaks of rainfall and increasing temperature on the entire planet. Several studies have been performed to estimate
