Defining metabolic zonation as a determinant of hepatocyte plasticity
Liver regeneration following injury occurs through several well-defined mechanisms, including the hypertrophy or hyperplasia (proliferation) of epithelial cells and the recruitment and differentiation of hepatic progenitor cells. In specific contexts, experimental evidence suggests that mature …

Predicting Plant Zonation in the Salt and Brackish Marshes of Georgia
<p>Tidal marshes provide important economic and environmental functions. There are 1,745 km<sup>2</sup> of tidal marsh habitat along the Georgia coast that can be separated into three distinct marsh types based on salinity levels. Tidal fresh, brackish, and salt marshes occur along a gradient that …

Microbial and Chemical Zonation and Mineral Weathering in the Middendorf Aquifer, South Carolina
… and origin of the chemical and microbiological zonation of the Cretaceous Middendorf aquifer, in the Coastal Plain of South Carolina, in light of the chemical evolution of groundwater along a flow path there. Some types of microbial activity, most notably aerobic respiration and iron reduction, …

Vertical zonation of three species of California limpets (Acmaeidae) as a function of predation
<p>Various studies indicate the acmaeid limpet species Collisella digitalis, Collisella pelta and Notoacmea scutum inhabit different vertical zones in the rocky-intertidal region. At Sunset Bay, Oregon, Shotwell (1950) found that C. digitalis was situated in the upper intertidal C. pelta inhabited …

Reliability Analysis of Tailings Storage Facility Embankments: Investigating the Effect of Zonation on Slope Stability
The stratified nature of tailings storage facilities (TSFs) remains a major stratigraphic or transformation uncertainty in slope stability assessment. Unlike natural soils, tailings are hydraulically deposited and develop alternating layers of coarse, dilative sands and fine, contractive slimes …

A study of the relationship between environmental conditions and salt marsh zonation at Langebaan Lagoon
… hydrological and ecological context. The zonation of the plant communities is a distinctive feature of the salt marshes at Langebaan. To establish the nature of this zonation and to achieve the stated objectives, transects were established at three sites around the lagoon. Tue vegetation …

The Efficacy of Immunotherapy in Preventing Liver Cancer and the Role of Metabolic Zonation in Its Development
In order to study the development and progression of liver cancer, as well as the efficacy of novel therapeutic strategies, accurate models of human disease are needed. In particular, in vivo mouse models capture critical characteristics that are relevant to human hepatocellular carcinoma (HCC). …

A Comparison of GIS Approaches to Slope Instability Zonation in the Central Blue Ridge Mountains of Virginia
To aid in forest management, various approaches using Geographic Information Systems (GIS) have been used to identify the spatial distributions of relative slope instability. This study presents a systematic evaluation of three common slope instability modeling approaches applied in the Blue Ridge …

Pluton Zonation Unveiled by Gamma-ray Spectrometry and Magnetic Susceptibility; A Case Study of the Sheeprock Granite, Western, Utah
… processes related to its chemical and physical zonation. Uranium ranges from 3.9 to 26.9 ppm (mean 12.7) and thorium from 1.7 to 125.7 ppm (mean 45.5). Similarities in spatial patterns and near normal distributions of U and Th imply minimal remobilization and secondary equilibrium of U.<p> …

Information extraction and integration in mineral exploration.
… most of the possible local lineament types. A zonation detector (a non-linear logic operator) indicates the presence or absence of lithologic zonation, the number and the types of zones using a series of automatically expanding moving windows. The ultimate window size represents the zonation …

Albian microbiostratigraphy (foraminifera and Ostracoda) of S.E. England and adjacent areas
… This project attempts to refine the existing zonation based on foraminifera, to correlate it with the existing Ammonite zonal scheme, and propose a detailed zonation based on Ostracoda which have been integrated with both the zonal schemes mentioned above. To achieve this, the …
