Structural sustainability of cambisol under different land use system Sustentabilidade estrutural de um cambissolo sob diferentes sistemas de uso

Revista Brasileira de Ciência do Solo, 2012
Incongruous management techniques have been associated with some significant loss of agricultural land to degradation in many parts of the world. Land degradation results in the alteration of physical, chemical and biological properties of the soil ...

An Experimental and Numerical Investigation on Compression-resilience Responses of Membrane Materials in Spiral Case Structures

工程科学与技术, 2018
Membranes play load-transferring roles between steel spiral cases and surrounding concrete in hydroelectric power plants. However, membranes are routinely recognized as linear-elastic materials in current engineering practices. The two most commonly-used

Evaluation of Soil Compaction of Calcimagnesic and Vertisol notill fields at the Chaouia Arid Land Context of Morocco

African and Mediterranean Agricultural Journal - Al Awamia
Soil compaction induced by agricultural machinery is widely recognized as a significant challenge in agricultural fields. This study evaluated soil compaction in six no-till vertisol and calcimagnesic field crops at the Chaouia region.

Deformation, fracture, and energy evolution characteristics of coal‐rock under dynamic–static combined loading

Energy Science & Engineering
Deep coal‐rock formations are subjected to complex stress environments characterized by high static stresses and dynamic disturbances. To study the damage, fracture, and energy evolution characteristics of coal‐rock under dynamic–static combined loading,

Soil susceptibility to compaction under use conditions in southern Brazil

Ciência e Agrotecnologia
The degree of soil compaction is intensified by its inadequate management, compaction being variable depending on soil type since even under identical management conditions, different types have different abilities to withstand load.

Compressive behaviour of the soil in buffer zones under different management practices in Finland

Agricultural and Food Science, 2008
Soil structure that favours infiltration is essential for successful functioning of vegetated buffer zones. We measured bulk density, air permeability and precompression stress in a clay soil (Vertic Cambisol) and a sandy loam (Haplic Regosol) in Finland,

Modelagem e determinação do estado crítico de consolidação a partir da relação massa e volume em solos canavieiros Modeling and determination of critical state of consolidation from mass-volume ratio in farmland

Revista de Ciências Agrárias, 2010
O trabalho teve por objetivo sugerir equações, as quais permitam estimar a densidade do solo (ρσp) e o volume total de poros (nσp), ambos referentes à pressão de preconsolidação (σp), propondo-os como indicadores físicos na avaliação ...
