Disappearance rate of a peatland in Dublany near Lviv (Ukraine) drained in 19th century [PDF]

open access: yesMires 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

Groundwater Level Change Management on Control of Land Subsidence Supported by Borehole Extensometer Compaction Measurements in the Houston-Galveston Region, Texas

open access: yesGeosciences, 2019
As much as 3.05 m of land subsidence was observed in 1979 in the Houston-Galveston region as a result primarily of inelastic compaction of aquitards in the Chicot and Evangeline aquifers between 1937 and 1979.

Rheological model parameters determination based on laboratory studies [PDF]

open access: yesНаучно-технический вестник Брянского государственного университета
Different types of models are used to study the stress-strain behavior of asphalt concrete mixture during compaction. For modeling it is necessary to know the values of model parameters in the whole range of changes in the characteristics of the ...

On Countable Compactness and Sequential Compactness [PDF]

open access: yesProceedings of the American Mathematical Society, 1984
If a countably compact T 3 {T_3} space X X can be expressed as a union of less then c c many first countable subspaces, then MA implies that X X is sequentially compact.

TREM2 haplodeficiency in mice and humans impairs the microglia barrier function leading to decreased amyloid compaction and severe axonal dystrophy

open access: yesNeuron, 2016
Summary Haplodeficiency of the microglia gene TREM2 increases risk for late-onset Alzheimer’s disease (AD) but the mechanisms remain uncertain. To investigate this, we used high-resolution confocal and super-resolution (STORM) microscopy in AD-like mice ...

Hot-Mix Asphalt Compaction Evaluation With Field Tests

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2014
The objective of this study is to determine the influence of field compaction conditions on hot-mix asphalt layers compaction. A large field test was carried out to assess the compaction degree variation under field conditions such as the type of layer ...

Compaction and quenching of high-z galaxies in cosmological simulations: blue and red nuggets [PDF]

open access: yes, 2014
We use cosmological simulations to study a characteristic evolution pattern of high redshift galaxies. Early, stream-fed, highly perturbed, gas-rich discs undergo phases of dissipative contraction into compact, star-forming systems (blue nuggets) at z~4 ...
