Fluorescent Photoinduced Electron Transfer (Pet) Cation Sensors Derived From Natural Products, Kenny Loo

Theses, Dissertations and Culminating Projects

Two new second generation fluorescent switches that are based on the chromophore-spacer-receptor architecture are reported in this thesis. The fluorescence modulation of these switches is a result of quenching or initiating photoinduced electron transfer (PET) between the chromophore and the receptors due to cation binding. These two molecules utilize an alkaloid, anabasine, as the proton receptor, and function as fluorescent off-on-off switches with decreasing pH. One of these molecules also utilizes a coumarin as the chromophore, making it the first rationally designed fluorescent PET system based on natural products. Further studies of two well-known first generation fluorescent switches to achieve …

Disease Outbreaks In Coupled Populations : An Application To Measles Spread In Cameroon, Kirsten Maggie Viz

Theses, Dissertations and Culminating Projects

Many childhood diseases can be modeled mathematically using a system of differential equations that group the overall population into compartments. Much research has been done to understand and control the spread of these diseases within a single population and between coupled populations with constant parameters. In this thesis, we are concerned with how a disease is spread through and between coupled populations using models with time-varying parameters and asymmetric coupling.

Measles outbreaks in the West African country of Cameroon present a good example of disease spread with seasonality. By dividing Cameroon into two subpopulations and using parameters that reflect recent …

Quantifying Atmospheric Nitrogen Deposition As A Nonpoint Source Pollution And Its Potential Effects On The Mullica River-Great Bay Ecosystem, Jennifer Haag

Theses, Dissertations and Culminating Projects

To characterize atmospheric nitrogen deposition and its potential impact on the Mullica River-Great Bay Estuary, atmospheric sampling was conducted at Rutgers University Marine Field Station in Tuckerton, New Jersey from March 2004 to March 2005. A total of 52 precipitation samples were collected on an event basis using a MIC wet-only automatic precipitation sampler. A total of 23 aerosol samples were also taken during this period of time with a high-volume aerosol sampler. Chemical analysis was performed using a Dionex Ion Chromatograph to determine the concentrations of nitrate and ammonium in precipitation and associated with aerosols. Nitrate concentrations for precipitation …

Effects Of Pre- And Post-Trip Activities Associated With A Residential Environmental Education Experience At The New Jersey School Of Conservation On Students’ Attitudes Toward The Environment, Lisa Cavern

Theses, Dissertations and Culminating Projects

Scholars of both general education and environmental education (EE) have suggested using targeted activities before and after field experiences may increase the assimilation of desired concepts by students (Ballantyne & Packer, 1996; Bogner, 1998; Dettmann- Easler & Pease, 1999; Flavell, 1979; Knapp & Poff, 2001; Marzano, Gaddy, & Dean, 2000). A search of the EE literature using the ERIC database for the years 1967-present found two studies that explored the use of additional activities to prepare for or reinforce concepts from zoo and garden programs (Farmer & Wott, 1995; Gutierrez de White & Jacobson, 1994), but none related to residential …

Environmental Restoration : The Catalyst Of A City's Successful Revitalization, A Potential Application Example, City Of Camden, New Jersey, Maria Del Rocio Bosch Clark

Theses, Dissertations and Culminating Projects

This thesis aims to concisely emphasize and demonstrate the importance of the connection between urban and natural environments, towards fostering a strong and healthy quality of life for its citizens.

The notion of applying an integrated comprehensive approach to city planning and environmental restoration (such as brownfields redevelopment) is lacking throughout many communities. On the other hand, "success stories" exist around the world that link a comprehensive city plan and environmental restoration to their successes. These attestations of accomplishments demonstrate that regardless of the geographical or economic circumstances, this thesis concept might be applied.

This thesis concept is simplified by …

Semantic Parsing Of Java I/O In Novice Programs For An Online Grading System, William Madden

Theses, Dissertations and Culminating Projects

Beginning programming students have access to sophisticated development tools that enable them to write syntactically correct code in a straightforward manner. However, code that compiles and runs can still execute poorly, or with unintended results. We present a tool, based on an open-source parser-generation product written in Java, that performs semantic analysis of novice Java code. Specifically, the present investigation concerns the semantics of Java output methods, particularly when they are enclosed within iterative structures in the language. The effort will be to guard against threats that such methods pose to system integrity and performance, intercepting them prior to runtime. …

Short-Term And Long-Term Effects Of High Intensity Forest Fires On Soil Phyllosilicates, Jennifer Rose Reynard

Theses, Dissertations and Culminating Projects

High intensity forest fires can alter the clay minerals found in soils. These minerals can be degraded, collapsed, as well as completely destroyed. Signatures of these fires may remain for years after the bums. To ascertain the impact of high intensity fire on soil physical properties, samples were collected from the area in and around the 2002 Hayman, Colorado, fire. These included burned samples from several areas within the perimeter of the fire (taken one to four months following the fire), unburned samples near the origin of the fire, as well as samples from areas of historic burns nearby. This …
