Water Quality Impacts From Agricultural Land-Use In The Karst Groundwater Basin Of Qingmuguan, Chongqing, China, Ted W. Baker Dec 2008

Water Quality Impacts From Agricultural Land-Use In The Karst Groundwater Basin Of Qingmuguan, Chongqing, China, Ted W. Baker

Masters Theses & Specialist Projects

Karst regions are composed of soluble rock, often limestone, which leads to the formation of fissures, sinkholes and water flow conduits such as caves. Pollutants in karst waters tend to be quickly directed and concentrated into these subsurface conduits. As a result of this and other factors, water resources are especially sensitive to contamination and pollution in karst areas. Pollutant concentrations going into fluvial systems travelling through the subsurface in karst areas are often very similar to the concentrations arriving at outlets such as springs. Areas connected by karst conduit flows must be distinctly determined and special attention should be …

Simulation Modeling Of Karst Aquifer Conduit Evolution And Relations To Climate, John D. Broome Dec 2008

Simulation Modeling Of Karst Aquifer Conduit Evolution And Relations To Climate, John D. Broome

Masters Theses & Specialist Projects

ABSTRACT Karst regions of the world that receive relatively similar amounts of precipitation display a wide variety of landscapes. It has been suggested (Groves and Meiman, 2005) that climates exhibiting larger discrete storm events have more dissolving power and consequently higher rates of conduit growth than climates with more uniform precipitation distributions. To study this concept, a computer program “Cave Growth” was developed that modeled the growth of a cross-section of a cave passage under dynamic flow and chemical conditions. A series of 46 simulation datasets were created to represent different climatic conditions. These simulations had the same total annual …

Kernel Density Estimation Of Traffic Accidents In A Network Space, Zhixiao Xie, Jun Yan Sep 2008

Kernel Density Estimation Of Traffic Accidents In A Network Space, Zhixiao Xie, Jun Yan

Earth, Environmental, and Atmospheric Sciences Faculty Publications

A standard planar Kernel Density Estimation (KDE) aims to produce a smooth density surface of spatial point events over a 2-D geographic space. However, the planar KDE may not be suited for characterizing certain point events, such as traffic accidents, which usually occur inside a 1-D linear space, the roadway network. This paper presents a novel network KDE approach to estimating the density of such spatial point events. One key feature of the new approach is that the network space is represented with basic linear units of equal network length, termed lixel (linear pixel), and related network topology. The use …

Searching For Binding Partners For The Novel Phkg1 Variant, Phkγ 181, Kishore Polireddy Apr 2008

Searching For Binding Partners For The Novel Phkg1 Variant, Phkγ 181, Kishore Polireddy

Student Research Conference Select Presentations

Phopshorylase kinase (PhK) is a hexadecameric holoenzyme made up of four different subunits in the arrangement (αβγδ)4 and has total molecular mass of 1.3MDa. Alpha and β are regulatory subunits, γ is catalytic, and δ is an intrinsic molecule of calmodulin. PhK is a serine threonine kinase with glycogenolytic regulatory functions. Our lab has recently discovered that the γ subunit can be alternatively processed to produce a truncated form of 181 residues (γ-181). This variant of γ contains a phosphorylation site for PK-C, and its activity is influenced by this phosphorylation. We are using a LexA based yeast two hybrid …
