Voorbeelden van compaction

• The increased size and use of machinery introduced soil problems, such as compaction, and required greater management skill.

• Explosives are now used in such diverse fields as welding, bulk cladding of plates, forming, sizing, powder compaction, hardening, and cutting.

• The system is expensive of time and energy but produces fine soil aggregates to planting depth with serious risks of compaction deeper in the profile.

• With continuing subduction the pelagic sediments might have been dragged beneath the accretionary prism leading to compaction and expulsion of large amounts of pore fluids.

• Many structural events are associated with compaction, including blastomere polarisation, blastomere flattening and gap junction formation.

• This is really not surprising, given that the compaction method pays no attention to the probabilities that play a crucial role in evaluation.

• However, minimum or zero tillage would not be suitable for soils that are susceptible to compaction, and for highly degraded soils.

• Here we examine the expression profile of uvomorulin at the cellular level, in oocytes and embryos up to and during compaction.
