Computational study of hydro-environmental processes of Poyang Lake, China
… representative evaluation of the hydraulic and environmental challenges is vital. In this research, a numerical model is developed and utilized to simulate the hydrodynamics and water quality of Poyang Lake and its surrounding river networks. The study couples an in-house 1-D river network …

Development of remote sensing tools and use of sensors onboard uavs for the study of coastal environmental processes
Los ecosistemas costeros constituyen una de las regiones más diversas y productivas globalmente y, al mismo tiempo, figuran entre las más vulnerables ante los efectos del cambio climático y la acción de otros factores antropogénicos. Sus consecuencias se están acrecentando y evolucionan a un ritmo …

Environmental drivers of coastal evolution
Coastal evolution is shaped by the processes that influence sediment transport at coastlines. The present morphology, sedimentology, and distribution of modern coastal landforms reflect the influence of Holocene environmental processes that have altered the availability and movement of sediment at …

Determination of the far-infrared properties of galaxies in the Coma cluster
… field in order to ascertain the extent to which environmental processes affect galaxy evolution. A comparison of the luminosity functions at 100 and 160 _m and the equivalent functions from the Herschel Virgo cluster survey Auld et al. (2013) showed similarities in both the functional form and …

Insights from spectral stacking on the Hi content of cluster galaxies in various environments: a tale of two clusters
… a unique opportunity to study the ongoing environmental processes influencing galaxy evolution. Optical studies have shown that galaxy clusters are typically home to a higher fraction of older elliptical, bulgedominated galaxies than the field which has a higher fraction of younger, …

Volatiles as a link between planetary interiors and the environment
… interiors influence magma evolution and environmental processes. Over appropriate timescales, Earth's mantle, crust, ocean, and atmosphere constitute coupled systems. The apparently synchronous Siberian Traps eruption and end-Permian mass extinction offer an ideal test case to study the …

MICROBIAL CONTROLS ON THE ENVIRONMENTAL FATE OF CARBON NANOMATERIALS
… their growing prevalence, the properties and processes controlling the degradation of CNM in the environment remain poorly understood. The primary purpose of this dissertation is to examine the role of environmental microorganisms in degrading CNM and to elucidate which CNM properties and …

Temporal playscape design within an existing landscape dynamic
… and responsibly. Taking cues from natural environmental processes, the design for a contemporary playscape within existing environmental conditions provides a refuge from city life for Boston area children. The design balances between the designed landscape and the natural landscape. …

Water and Power: The Environmental Politics of a Virginia Reservoir
… attempts to problematize the power relations in environmental administration and decision making through the analytical lens of environmental discourse and ethics. It argues that developments in environmental politics reveal a marked increase in democratic involvement through an emerging …

EMBODIED POLITICAL ECOLOGIES OF HEALTH: A CASE STUDY OF ALCOHOL AND INFECTIOUS DISEASE IN THE UPPER WEST REGION OF GHANA
… the spread of hepatitis b, including the social environmental processes that underwrite these links. Thematic analysis of nine focus groups with residents (n=88) and seven key informant interviews indicate that the relationship between alcohol misuse and hepatitis is underwritten by several …

INFORMATION BASED ADAPTIVE PATH PLANNING AND SAMPLING FOR ENVIRONMENT MONITORING
… physical sample collection for understanding the environmental processes. We first explain the two adaptive planning algorithms for estimating scalar environmental fields with bounds on the mission time. These algorithms adapt the path during the mission based on the recently collected …

The Morphology-Density Relation of Galaxies at z~1.6
… relation may be driven by mass-dependent environmental processes.

Environmentally-Driven Variation in the Population Dynamics of Gulf Menhaden (<i>Brevoortia patronus</i>)
… ontogeny and how such variation relates to environmental processes. We utilized a suite of fishery-dependent and –independent, remote sensing, modeled, and <em>in situ</em> data to explicitly model the relationship between the condition, distribution, and growth of Gulf Menhaden and river …

Fish Community Assembly At Multiple Spatial Scales In East Texas Streams
<p>Stream communities are structured by environmental processes that vary in strength across different spatiotemporal scales. Therefore, revealing how stream fish communities are influenced by environmental gradients may clarify how communities respond to disturbance associated with anthropogenic …

Functional data methods for climatological processes
Many climatological and environmental processes take the form of trajectories or surfaces. In the language of Statistics, these observations can be considered as functional data and the tools for studying the behavior of functional data define a framework known as Functional Data Analysis (FDA). In …

Modelling of environmental parameters in lake environmnets using neural networks
Aquatic pollution is one of the most serious environmental issues that the human kind has to deal, especially the last decades. Therefore, the aquatic environments are suffering a great environmental pressure as well. Since the lakes are having about the 90% of the Earth’s liquid freshwater, their …

Recognition of Cations and Anions by Lanthanide Complexes
… oxoanions are involved in many biological and environmental processes. Biologically, these ions have roles in aging and in the pathogenesis of a wide variety of disorders including neurodegenerative diseases such as Alzheimer’s and Parkinson’s, inflammation, reperfusion injury, bacterial …

Phosphorus in the Environment and its Role in Anaerobic Iron Corrosion
… microbial nutrition, corrosion and other environmental processes. It is commonly assumed that phosphorus occurs exclusively as phosphate (+5) in nature. In fact, although phosphate is undoubtedly dominant in many systems, phosphorus compounds with lower oxidation states (reduced …

The Influence of Heterogeneous Landscapes on Banded Mongoose (Mungos mungo) Behavior in Northern Botswana: Inferences about Infectious Disease Transmission
… did natural dens which became unsuitable through environmental processes (e.g., collapse). We also document the occurrence of nighttime activity for this species, perceived to be strictly diurnal. These data provide information critical to the development of robust computational models and …
