Lithostratigraphic and structural controls of uranium mineralization in the Kiggavik East Zone, Centre Zone, and Main Zone deposits, Thelon Basin, Nunavut
… the Thelon Fault. Detailed study at the Centre Zone deposit revealed that during Phase 1 mineralization steeply dipping D- and P-shears served as conduits for fluids to move through and penetrate earlier-formed ductile structures. The fluids preferentially infiltrated through, and precipitated …

Exploring the Shivwits production zone
The Shivwits Plateau is situated on the Arizona Strip in the northwest corner of Arizona. It is a relatively unexplored area rich in archaeological resources. This study provides three areas of exploration of the prehistoric Virgin Anasazi Pueblo period. Three research questions are posed. Are …

The Grey Zone in Doping
… these facts, it can be concluded that a zone can be situated between uncontested doping products, such as injectable anabolic steroids, diuretics and growth hormone, and products with doubtful effects on the performance or products not listed on the WADA list of prohibited substances. …

Fukushima Exclusion Zone Survival Handbook
… Survival Handbook of the Fukushima Exclusion Zone” is a fiction and an imaginative guide that describes how to coexist in a future radioactive world. It is designed for humans -- residents and visitors returning to the site--and nonhumans--flora and fauna and nuclear waste itself. Based on an …

New Dilemma Zone Mitigation Strategies
… right decision and can place them in the dilemma zone. Advance warning systems (AWS) have been used to provide information about the downstream traffic signal change prior to approaching the intersection. On the other hand, advance warning systems increase drivers approach speed according to the …

Advances in Subduction Zone Processes
Subduction zones are an important recycling center at which material from the exterior of the Earth is transported to Earth's interior. The processes that occur along subduction zones have important implications for elemental cycles, geodynamics, and material mass transport. The cold, dense …

Subduction zone wave guides : deciphering slab structure using intraslab seismicity at the Chile-Peru subduction zone
Subduction zones are regions of intense earthquake activity up to great depth. Sources are located inside the subducting lithosphere and, as a consequence, seismic radiation from subduction zone earthquakes is strongly affected by the interior slab structure. The wave field of these intraslab …

Computer aided floating zone growth of Germanium-Silicon crystals in a resistance heated multi-zone furnace
… growth furnace <br>-- the FMF-module (Floating Zone Furnace with Rotating Magnetic <br>Field) -- is under development for crystal growth experiments on <br>the International Space Station. By using global simulations and <br>the inverse modeling method, its optimal design and its <br>performance …

Oceanic mixed layer entrainment zone dynamics
… model is augmented to include an entrainment zone with finite thickness. The role of entrainment shear production of turbulent kinetic energy is investigated by comparing model results that include the new entrainment zone with observations at Ocean Weather Station Papa in the North Pacific …

Work Zone Analysis Under Detour Settings
A new approach of work zone delay cost analysis is developed to understand the implications of detours. This method, unlike any of the previous methods, is based on the impacts within the transportation network and let users find the shortest paths which will eventually come to equilibrium. The …

A Near-Zone to Far-Zone Transformation Process Utilizing a Formulated Eigenfunction Expansion of Spheroidal Wave-Harmonics
… need arises to numerically extrapolate the far-zone performance of a radiating structure from its known (or assumed known) near-zone electromagnetic field. Mathematical processes developed to accomplish such a task are known in the literature as near-zone to far-zone transformations (NZ-FZTs) as …

The Development of a Hydrological Buffer Zone Strategy for Designating the Mesotope Protection Zone of Raised Mire Systems
The overall aim of this thesis has been to develop a pragmatic strategy to aid decisionmaking concerning the management of raised bogs for future sustainability, and specifically to provide a tool to identify the extents and locations of those areas around the bog margins within which water tables …

In the Zone: the Effects of Soil Pipes and Dunes on Hyporheic and Riparian Zone Hydraulics and Biogeochemistry
… in stream corridors. The focus is hyporheic zones which form the interface between surface water and groundwater below and adjacent to stream channels, and riparian zones which form the interface between channels and adjacent uplands, both of which can attenuate pollutants. In this context, …

Comparison of concentrations in the breathing zone
The concentrations in the "breathing zone" were analyzed on three human subjects in simulating work conditions. The experiments were carried out in a wind tunnel having 40&feet; x 12&feet; x 9&feet; dimensions. Ethanol vapor mixed with nitrogen was used as a tracer gas. Samples were taken at the …

Getting comfortable in the zone with S3DComfortZone
This thesis explains the creation of S3DComfortZone; a visualization tool integrated into the development pipeline displaying the virtual comfort zones of stereoscopic 3D devices. This tool addresses the need for visualization information of unique comfort zones across multiple stereoscopic 3D …

Dynamic vegetation Roughness in the riparian zone
Vegetation in the floodplain plays an important role in dictating the hydraulics of an open channel river system. While vegetation is beneficial to the biological productivity of the river system, it can also increase flood risk due to increased channel roughness. Traditional means of predicting …
