Subsoil Compaction: A hidden form of Soil Sealing in Europe [PDF]
, 2001 There are two definitions of ‘soil sealing’: (I) ‘covering (sealing) the soil surface by impervious materials, e.g. concrete, metal, glass, tarmac and plastic’; and (II) ‘changing the nature of the soil such that it behaves as an impermeable medium, e ...

The effects of tyre systems on the depth and severity of compaction [PDF]
, 2006 High value crops such as peas for the frozen vegetable market have to be harvested at the optimum point for quality, regardless of field conditions. Six wheeled pea harvesters with a gross weight of 27 t, giving a wheel load of 4.5 t are required to move

Reducing deep soil compaction through strain modification under different wheel arrangements
, 2002 New mechanisation methods associated with increasing loads have the potential to cause undesirable deep compaction, which is difficult, expensive and in some cases impossible to alleviate.

Shear Strength Characteristics of Cemented Clayey Sand Soil [PDF]
Journal of Engineering Research - Egypt, 2021 Several techniques of soil stabilization are available to improve the behavior of many types of soil. The addition of cement to soils have proved a significant effect on the geotechnical properties of treated soils.

Combined sensor of dielectric constant and visible and near infrared spectroscopy to measure soil compaction using artificial neural networks [PDF]
, 2014 Soil compaction is a widely spread problem in agricultural soils that has negative agronomic and environmental impacts. The former may lead to poor crop growth and yield, whereas the latter may lead to poor hydraulic properties of soils, and high risk to

Building Principles for Constructing a Mammalian Blastocyst Embryo
Biology, 2018 The self-organisation of a fertilised egg to form a blastocyst structure, which consists of three distinct cell lineages (trophoblast, epiblast and hypoblast) arranged around an off-centre cavity, is unique to mammals.

Efficient Static Compaction Techniques for Sequential Circuits Based on Reverse-Order Restoration and Test Relaxation [PDF]
, 2005 The paper present efficient reverse-order-restoration (ROR)-based static test compaction techniques for synchronous sequential circuits. Unlike previous ROR techniques that rely on vector-by-vector fault-simulation-based restoration of test subsequences,

Disappearance rate of a peatland in Dublany near Lviv (Ukraine) drained in 19th century [PDF]
Mires and Peat, 2017 We aimed to determine the rate of subsidence of a peatland over 133 years since its drainage, and to evaluate the relative contributions of compaction and oxidation to this process. Reliable determination of this proportion is problematic. The results of
