The spatiotemporal variability in precipitation could have a significant impact on ground subsidence. In this paper, we utilize previously developed one-dimensional theory of consolidation for two-fluid system, the generalization Biot's theory, to investigate time-dependent fluid flux across surface an unsaturated soil solid deformation and pore pressure responses. We consider three prescribed ...

This paper presents 2,000 years of settlement and land use within the Lake Pátzcuaro Basin, Mexico. Three findings challenge the conclusions of previous research. We show (i) that initial land degradation was caused by settlement, not by agriculture; (ii) that population density inversely correlates with erosion; and (iii) that land degradation was associated with European Conquest but not from...

Rats can learn to forage among olfactory cues to associate one with reward in only 3 massed trials. The learning is achieved in less than 10 min and results in a memory trace lasting at least 1wk week. To study the neuro-anatomical circuits involved in the memory formation we used immunoreactivity to the immediate early gene c-fos as a marker for neuronal activity induced by the learning. The p...

In practical engineering projects, overconsolidation plays an irreplaceable role in the calculation of silt consolidation settlement. Based on a series systematic tests conducted reconstituted soft clay different cities Guangdong-Hong Kong-Macao Greater Bay Area, behavior under depths was studied. According to these tests, shape curves ratio with depth similar that compression curves. Moreover,...

Software development can be characterized in terms of prototype (or initial design) phases, expansion phases and consolidation phases. During a consolidation phase, some relationships, initially modeled using inheritance, may be evolved to aggregations. Also, during consolidation, abstrasct classes are sometimes de ned to capture behavior common to two or more existing classes. In this paper, w...

Sleep-dependent memory consolidation is observed following motor skill learning: Performance improvements are greater over a 12-h period containing sleep relative to an equivalent interval without sleep. Here we examined whether older adults exhibit sleep-dependent consolidation on a sequence learning task. Participants were trained on one of two sequence learning tasks. Performance was assesse...

Negative skin friction occurs when concrete piles are situated in soft soils, consolidating soilmass, etc., resulting in a downward force that increases loading on shaft piles and reduces the bearing capacity of the piles. A new concept based on the shifting rate of piles, and the settlement rate of the surrounding soils has been suggested far the study of negative skin friction. Negative skin ...

This paper describes an innovative design of a newly developed large test setup for testing the performance of footings supported on soft clay reinforced with granular columns. This advanced testing method is used to examine the settlement of footings supported on granular columns. Two important features of the equipment are a the axial loading system which allows samples to be consolidated und...
