Parâmetros de compressibilidade e permeabilidade ao ar de solos sob plantio direto
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2014-10-24)
The compaction process can be evaluated by soil compression curve. The curved segment of the compression curve shows the elastic deformation, while the linear segment represents the elastic deformation. The soil capacity ...
Espaço poroso avaliado por tomografia e propriedades hídricas e mecânicas em solos argilosos sob culturas anuais e campo natural
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em Ciência do SoloCentro de Ciências Rurais, 2020-07-16)
The growing demand for food and energy causes an intensification in agriculture, which uses
larger machines and results in high pressures applied to the soil. As the pressures increases there
are changes in the soil ...
Mapeamento do solo da sede Ecoville da UTFPR com relação à concentração de radônio 222Rn
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia CivilUTFPR, 2016-11-23)
Radon (222Rn) is the second most common cause of the world of lung cancer, behind cigarette, and, in non-smoking, is the main cause. Resulting from the uranium decay, element that is very much present in the soil, radon ...
Determinação da resistência mecânica e da permeabilidade de concreto permeável: comparação entre concretos usinado e moldado em laboratório
(Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de Tecnologia, 2020-03-04)
Faced with the soil sealing caused by urbanization and the inefficiency of drainage systems, heavy or
lasting rainfall causes disruption to the population, as precipitated water generates runoff that forms
floods. To ...
Estudo da permeabilidade de meios porosos com solução polimérica
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Química, 2015-12)
The permeability of material is a relevant characteristic of porous media that can be applied on several science and engineering fields. Polymers are chemical compounds of high molecular weight and those which are water ...
O solo e sua permeabilização
(Universidade Tecnológica Federal do ParanáMedianeiraBrasilEspecialização em ensino de CiênciasUTFPR, 2018-08-20)
This work had as its theme the permeability of the soil and its relevant variations and coverages. Being analyzed the consequences of an unplanned landfill
and the result within a public organization fostering for future ...
Root volume and dry matter of peanut plants as a function of soil bulk density and soil water stress
(2008-04-01)
Soil compaction may be defined as the pressing of soil to make it denser. Soil compaction makes the soil denser, decreases permeability of gas and water exchange as well as alterations in thermal relations, and increases ...
